Description
Technical field
The present invention relates to desk, more particularly to a kind of brake apparatus for same table movable axis.
Background technology
Now, same table with its can carry out according to actual needs the characteristics of height of table top regulation in live and work further
Widely it is employed, such as lifts computer desk, lifting dais, self-powered platform.Wherein mainly divide by the control mode of lifting
For electric up-down and hand-operated lifting, electric elevatable table control and operation relative ease, can preferably be started by motor control
Lifting and braking stop, but electric elevatable table is comparatively expensive, and weight is also larger, while need to expend electric power, are
Although this hand-operated lifting table is not so good as electric elevatable table in manipulation, in general user does not require that very for manipulation precision
Height, so hand-operated lifting table is still widely used in each occasion.
The lifting implementation of hand-operated lifting table is also more, and main is such as drawn using gas bar, screw mandrel, spring, together
Sample also has corresponding mode of braking to realize that the lifting of same table positions.It can be set in many hand-operated lifting tables moveable
Axle or wire, such as by spring draw axle or wire, drive desk to lift by spring force, when need keep same table
Height when, only the axle or wire that are connected with spring need to be braked.It can be seen that the quality of brake apparatus directly influences liter
The lifting effect of table drops.

Embodiment
Fig. 1 is the structural representation of a preferred embodiment of the brake apparatus of the present invention, and Fig. 2 is brake apparatus in Fig. 1
Element exploded view.Wherein brake apparatus include end cap 1, spring 2, mandrel 3, roller 4, shift fork 5, mounting bracket 6, brake cable 7,
Housing 8, pin 9 and extended stabilizer 10, and also show the movable axis 11 being installed in brake apparatus.
The brake apparatus of the present embodiment uses a pair of mandrels 3, is oppositely arranged, and each mandrel 3 is configured with accordingly respectively
End cap 1, spring 2 and roller 4.Spring 2 is installed on mandrel 3, and movable axis 11 is each passed through end cap 1, mandrel 3 and housing 8, and
It can move or rotate axially therein, i.e., end cap 1, mandrel 3 and housing 8 are respectively provided with the hole or axially logical for being available for installing movable axis 11
Road.The part of mandrel 3 is arranged in housing 8, and is maintained at spring 2 and mandrel 3 by the threaded connection of end cap 1 and housing 8
The inside of housing 8, roller 4 are arranged in the hole on mandrel 3.When spring 2 is not acted on by external force, spring 2 is acted on mandrel 3
Spring force, mandrel 3 is pushed in housing 8, i.e. a pair of mandrels 3 by spring 2 spring-force driven dual, it is close to each other.Pass through pulling
Part of the mandrel 3 outside housing 8, the spring force of spring 2 can be overcome and part mandrel 3 is pulled out into housing 8.
Mounting bracket 6 is fixedly mounted on housing 8, and such as using the similar connected mode of welding, both can also integration
Make.Include hole 12 in mounting bracket 6, so as to be fixed to the installation site of needs by hole 12.In mounting bracket 6
Also including a pair of extended stabilizers 10, each extended stabilizer 10 is pivotally connected by pin 9 with a shift fork 5 respectively, and the one of a pair of shift forks 5
End is separately positioned on a pair of mandrels 3 and is located in the recess outside housing 8, and is provided with brake cable 7 in the other end of shift fork 5, from
And when pulling brake cable 7, the lever that is formed by shift fork 5, pin 9, the spring-force driven dual of spring 2 can be overcome, by part core
Axle 3 pulls out from housing 8.
The working method of the brake apparatus of this implementation is described further below by way of Fig. 3 and Fig. 4.
Fig. 3 and Fig. 4 be in Fig. 1 along A-A to sectional view, the brake apparatus for respectively illustrating this implementation is in locking state
And releasing orientation.
As shown in figure 3, one end that mandrel 3 enters housing 8 has wedge structure, and enclosure interior has and mandrel 3
The wedge space that wedge structure is engaged, both are engaged the depth capacity for defining that mandrel 3 enters housing 8.Simultaneously from Fig. 3 and
Fig. 4 is visible, during mandrel 3 enters housing 8, is arranged on wedge structure of the roller 4 in the hole of mandrel 3 prior to mandrel 3
Contacted with the inwall of housing 8, and roller 4 is also in contact with movable axis 11 simultaneously, so that under the spring-force driven dual of spring 2,
Mandrel 3 and its interior roller 4 are maintained at a fixed position, and the inwall of housing 8 is applied with along the radial direction of movable axis 11 simultaneously to roller 4
The component of movable axis 11 is pointed to, is transmitted by roller 4 and puts on movable axis 11, clamping force is formd to movable axis 11, reaches limitation
The purpose that movable axis 11 is moved axially or rotated.It is its locking position by the position restriction that mandrel 3 enters depth capacity in housing 8
Put, when mandrel 3 is in locked position, the brake apparatus of the present embodiment is in locking state, and movable axis 11 is by limitation activity.From
Operation principle above can also be easy to think of, and by selecting the spring of different coefficient of elasticity, can obtain different clampings
Power, can accordingly it be selected according to being actually needed.
As shown in figure 4, when pulling brake cable 7, one end that a pair of shift forks 5 are located at brake cable 7 is close to each other, passes through shift fork
5 and the lever system that is formed of pin 9, shift fork 5 be arranged on the other end of the indent of mandrel 3, resist the spring force of spring 2 by part core
Axle 3 pulls out housing 8, and now mandrel 3 have left locked position, and inwall of housing 8 hardly provides folder to roller 4 during this
Clamp force, so as to which movable axis 11 can be moved axially or rotated.Mandrel 3 is left into residing other positions after locked position to limit
For its released position, when mandrel 3 is in released position, the brake apparatus of the present embodiment is in releasing orientation, and movable axis 11 can
Activity.
It is visible by the description of the present embodiment, brake apparatus of the invention have it is simple in construction, it is easy to operate；Wearing terrain
(roller) is smaller and is conveniently replaceable, and saves spare parts cost；The advantages that adjusting clamping force easy (being adjusted by spring).And this reality
Apply the roller of example setting and on-fixed or be limited in mandrel, it is to have certain activity space in the radial direction movable axis
, so as to which when the diameter of movable axis changes within the specific limits, brake apparatus can be equally applicable, widen being applicable for product
Scope.
Preferred embodiment of the invention described in detail above.It should be appreciated that one of ordinary skill in the art without
Creative work can is needed to make many modifications and variations according to the design of the present invention.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical scheme, all should be in the protection domain being defined in the patent claims.
