Abstract
The utility model relates to a valve needle fixing assembly which comprises a piston fixing sleeve, a piston and a valve needle, wherein the piston is arranged in the piston fixing sleeve in a slideable 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 mutually parallel; a driven lever hole is formed in the side part of the fixing sleeve; a lever groove is arranged in a position of the piston, which is close to the driven lever hole. According to the valve needle fixing assembly disclosed by the utility model, the valve needle is driven by the piston to move, and the center lines of the piston and the valve needle are parallel, thus during working, the valve needle can not be deviate; the driven lever hole and the lever groove in the fixing sleeve and the piston can be matched with a round-head lever, and the piston is driven by the round-head lever to move, thus the valve needle fixing assembly is simple and stable in structure, small in working abrasion and long in service life.
Description
Technical field
The utility model 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, belongs to TOP-TIP component technology field.
Background technology
Existing needle is fixed on one end of lever by a straight pin, lever is in the time of 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 when work, and service life is short.
Utility model content
The utility model object is the needle fixation kit that a kind of Stability Analysis of Structures, long service life are provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: 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, be provided with lever slot near on the position of driven lever mouth.
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 utility model compared with prior art has following advantages:
The needle fixation kit of the utility model scheme, needle move through piston driving, piston is parallel with the center line of needle, while therefore work, 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 solutions of the utility model are described further:
Accompanying drawing 1 is the schematic diagram of needle fixation kit described in the utility model;
Accompanying drawing 2 is the schematic diagram of a kind of embodiment of needle fixation kit described in the utility model;
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 drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of needle fixation kit described in the utility model, 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, be provided with lever slot 5 near on the position of driven lever mouth 4; The sidepiece of described piston 2 is provided with 6, two seal grooves 6 of two seal grooves and is separately positioned on the both sides, front and back of 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 to move, and then drives needle 3 to move.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The needle fixation kit of the utility model scheme, the piston 2 that moves through of needle 3 drives, the centerline collineation of piston 2 and needle 3, while therefore work, 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, drive piston movement by round end lever 7, and simple in structure, stable, service wear is little, long service life.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
