Abstract
The invention discloses a valve needle fixing component which comprises a piston fixing sleeve, a piston and a valve needle. The piston is arranged in the piston fixing sleeve in a sliding manner; the valve needle is arranged at the front end of the piston; center lines of the piston fixing sleeve, the piston and the valve needle are parallel to one another; a driven lever port is formed in a side part of the fixing sleeve; a lever groove is formed in a position, which is close to the driven lever port, of the piston. According to the valve needle fixing component, the movement of the valve needle is driven by the piston, and the center lines of the piston and the valve needle are parallel to each other, so when the valve needle fixing component works, the valve needle does not generate offset. Moreover, the driven lever port in the fixing sleeve and the lever groove in the piston can be matched with a round head lever, the piston is driven to move through the round head lever, and the valve needle fixing component is simple and stable in structure, small in service wear and long in service life.
Description
Technical field
The present invention relates to the needle fixation kit of a kind of needle assembly of TOP-TIP, particularly a kind of Stability Analysis of Structures, long service life, belong to TOP-TIP component technology field.
Background technology
Existing needle is fixed on one end of lever by a straight pin, lever is when motion, lever can drive straight pin and needle to move toward a lateral deviation, therefore, when needle moves reciprocatingly for a long time, easy stress deformation, even fractures, and two fixed cylinder diameter of straight pin is less, insufficient strength, easily weares and teares during work, and service life is short.
Summary of the invention
Technical problem for above-mentioned existence, the object of the invention is: the needle fixation kit that has proposed a kind of Stability Analysis of Structures, long service life.
Technical solution of the present invention is achieved in that a kind of needle fixation kit, comprises piston fixed cover, piston and needle; Described piston is slidably disposed in piston fixed cover; Described needle is arranged on the front end of piston; The center line of described piston fixed cover, piston and needle is parallel to each other; The sidepiece of described fixed cover is provided with driven lever mouth; On described piston, near driven lever Kou position, be provided with lever slot.
Preferably, the sidepiece of described piston is provided with seal groove.
Preferably, described seal groove has two, and two seal grooves are separately positioned on the both sides of lever slot.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Needle fixation kit of the present invention, needle move through piston driving, piston is parallel with the center line of needle, while therefore working, needle can not be offset; Driven lever mouth and lever slot on fixed cover and piston can coordinate round end lever, and by round end lever drives piston movement, simple in structure, stable, service wear is little, long service life.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the schematic diagram of needle fixation kit of the present invention;
Accompanying drawing 2 is the schematic diagram of a kind of embodiment of needle fixation kit of the present invention;
Wherein: 1, fixed cover; 2, piston; 3, needle; 4, driven lever mouth; 5, lever slot; 6, seal groove; 7, round end lever.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described.
As shown in Figure 1, a kind of needle fixation kit of the present invention, comprises piston fixed cover 1, piston 2 and needle 3; Described piston 2 is slidably disposed in piston fixed cover 1; Described needle 3 is arranged on the front end of piston 2; The center line of described piston fixed cover 1, piston 2 and needle 3 is on same straight line; The sidepiece of described fixed cover 1 is provided with driven lever mouth 4; On described piston 2, near on the position of driven lever mouth 4, be provided with lever slot 5; The sidepiece of described piston 2 is provided with the both sides, front and back that 6, two seal grooves 6 of two seal grooves are separately positioned on lever slot 5.
As shown in Figure 2, piston fixed cover 1 is fixed on a side of a round end lever 7, and the driven end of round end lever 7 enters in lever slot 5 through driven lever mouth 4, and round end lever 7 utilizes lever principle to drive piston 2 motions, and then drives needle 3 motions.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Needle fixation kit of the present invention, the piston 2 that moves through of needle 3 drives, the centerline collineation of piston 2 and needle 3, while therefore working, needle 3 can not be offset; Driven lever mouth 4 and lever slot 5 on fixed cover 1 and piston 2 can coordinate round end lever 7, by round end lever 7, drive piston movement, and simple in structure, stable, service wear is little, long service life.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
