Description

The pen that has standby ink cartridge

Technical field

The utility model relates to a kind of pen, relates in particular to a kind of pen that has standby ink cartridge.

Background technology

In the penholder of tradition pen; the thin-walled rubber bag tank that a splendid attire ink is arranged; the outside of rubber bag tank also has a metal protection protector and setting-out reed, is outside its deficiency: rubber bag tank insecurely leaked easily with being connected of nib, and the time has been grown; rubber bag tank is easily aging; even can be sticked together with protective sleeve, cause breakage to leak, and the rubber bag tank volume is limited; ink inventory is few, and writing time is shorter.

Summary of the invention

The purpose of this utility model is to provide a kind of pen that has standby ink cartridge, and it need not rubber bag tank and its outer metal protection protector, and a standby ink cartridge is arranged, and stores more ink, and writing time is longer, to overcome above-mentioned deficiency.

For realizing above-mentioned purpose; technical solution of the present utility model is: remove the original rubber bag tank of traditional pen and its outer metal protection protector; adopt spring-piston structure and main parts size with being threaded or welding; increase a standby ink cartridge; to avoid the aging trouble of bringing of capsule can increase the reserves of ink again, prolong writing time.

The utility model comprises nib, penholder and a chamber, it is characterized in that: in described the chamber 4, be provided with a spring 2, one end of this spring links to each other with spring base 1, the other end links to each other with the non-return valve 5 of standby ink cartridge 8 ends, the center of spring 2 is provided with a capillary 3, and its end passes spring base 1 and is connected with penholder 12; The outside of standby ink cartridge 8 also is provided with piston 7 and protective sleeve 9, and this protective sleeve links to each other with a chamber 4 with ink cartridge switch 10 by screw thread 13,13 ' respectively.

The connected mode of described chamber 4 and penholder 12 is to be spirally connected or to weld.

The utility model has the advantages that: the rubber bag tank and its outer metal protection protector that do not need ink reservoir; adopt screw thread to add the mode that is tightly connected of packing ring or welding between each main parts size; this had both been avoided rubber bag tank to be connected firm leaking and the capsule breakage that the brings trouble of leaking that wears out of causing with nib; increased the volume space in a chamber again; set up a standby ink cartridge and can store more inks, prolong writing time.

The specific embodiment

Below in conjunction with accompanying drawing the utility model and the specific embodiment thereof are described in further detail.

Referring to accompanying drawing, the utility model comprises nib, penholder and a chamber, it is characterized in that: in described the chamber 4, be provided with a spring 2, one end of this spring links to each other with spring base 1, and the other end links to each other the center of spring 2 with the non-return valve 5 of standby ink cartridge 8 ends, be provided with a capillary 3, its end passes spring base 1 and is connected with penholder 12; The outside of standby ink cartridge 8 also is provided with piston 7 and protective sleeve 9, and this protective sleeve links to each other with a chamber 4 with ink cartridge switch 10 by screw thread 13,13 ' respectively.

The pen suction; earlier with screw thread 13 ' unscrew; protective sleeve 9; ink cartridge switch 10 and switch fixator 11 are removed simultaneously; then nib 6 is inserted in the ink bottle; compress the upper end of standby ink cartridge 8 repeatedly with finger; the upper end of springs 2 is just compressed in its lower end by non-return valve 5; piston 7 also can be with standby ink cartridge 8 to moving down; the upper end of capillary 3 is passed non-return valve 5 and is entered in the standby ink cartridge 8; when finger unclamps; spring 2 will reset; at this moment; piston 7 and against current valve 5 also can with on move; upper end capillaceous then breaks away from standby ink cartridge 8; in the process that spring 2 stretches repeatedly; piston 7 is drawn into ink in the chamber 4 by capillary 3 and hollow penholder 12; after the ink in a chamber 4 is filled with; ink will be inhaled in the standby ink cartridge 8 and store; at last protective sleeve 9 is tightened by screw thread 13 ' reduction; after the ink in the chamber 4 is used up; can ink cartridge switch 10 be screwed by screw thread 13; make its lower end oppress standby ink cartridge 8; make standby ink cartridge 8 together with piston 7; non-return valve 5 together moves down; the upper end of capillary 3 will be passed non-return valve 5 and enter in the standby ink cartridge 8, thereby can continue to have ink to write usefulness by capillary 3 for nib 6, and switch fixator 11 can prevent to deviate from when ink cartridge switch 10 from unscrewing; non-return valve 5 is except that export the inks ink only import but no export by capillary 3.Connected mode between chamber 4 and the penholder 12 is not limited to be spirally connected or weld, and other connected modes are also at the row of this patent protection.
