Abstract
The utility model relates to a driven component for a valve needle. The driven component comprises a lever, a piston fixed sleeve, a driven piston and the valve needle, wherein the lever comprises a connecting part, a driving end and a driven end, the connecting part is provided with a connecting hole, the cross sections of the driving end and the driven end are in an arc shape, the driven piston is arranged in the piston fixed sleeve in a sliding way, the valve needle is arranged at the front end of the driven piston, a lever mouth is formed in the side part of the piston fixed sleeve, a driven groove is formed in the side part of the driven piston and near the lever mouth, and the driven end penetrates through the lever mouth and enters a lever groove. With the driven component for the valve needle works, as the contact surface between the driven end and the driven piston is small, the friction between the driven end and the driven piston is little, and the driven end and the driven piston are difficult to wear and fracture, the whole strength is strong, the structure is simple, and the cost is low; and as the driven end of the lever drives the driven piston to slide along the piston fixed sleeve, the valve needle does reciprocating motion along with the driven piston and can not deviate, and the service life is long.
Description
Technical field
The utility model relates to the assembly of the needle in a kind of TOP-TIP, and particularly the driven subassembly of a kind of Stability Analysis of Structures, frictional resistance is little, cost is low needle, belongs to TOP-TIP component technology field.
Background technology
The driven subassembly of existing needle is comprised of lever and needle, and the drive end of lever and driven end are forked, and needle is connected with the driven end of lever by straight pin; The driven subassembly of this structure, the intensity of the bifurcation structure that the driven end of lever is equal is lower, and lever is when work, end easy fracture, the contact-making surface between driven end and straight pin is larger, and frictional resistance is high, easily impaired, and bifurcation structure is comparatively complicated, and processing cost is high.
Utility model content
The utility model object is the driven subassembly that a kind of Stability Analysis of Structures, frictional resistance is little, cost is low needle 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 driven subassembly of needle, comprises lever, piston fixed cover, relay piston and needle; Described lever comprises the connecting portion and the drive end and the driven end that are arranged on lever two ends being arranged near lever middle part; On described connecting portion, be provided with connecting hole; The cross section of described drive end and driven end is circular-arc; Described relay piston is slidably disposed in piston fixed cover; Described needle is arranged on the front end of relay piston; The center line of described piston fixed cover, relay piston and needle is parallel to each other; The sidepiece of described piston fixed cover is provided with lever mouth; The sidepiece of described relay piston is provided with driven slot, and driven slot is arranged near on the position of lever mouth; Described driven end passes lever mouth, and enters in lever slot.
Preferably, described drive end and driven end are all spherical shape.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The driven subassembly of the needle of the utility model scheme, the drive end of lever and driven end cross section are circular-arc, and therefore, in when work, the contact-making surface between driven end and relay piston is little, and friction is not few, easy to wear, fracture, and bulk strength is high, simple in structure, and cost is low; The driven end of lever drives relay piston to slide along piston fixed cover, and needle is followed relay piston and moved reciprocatingly, and needle can not produce skew, high life.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
The schematic diagram of the driven subassembly that accompanying drawing 1 is needle described in the utility model;
Wherein: 1, lever; 2, drive end; 3, driven end; 4, connecting hole; 5, piston fixed cover; 6, relay piston; 7, needle; 8, lever mouth; 9, driven slot.
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, the driven subassembly of a kind of needle described in the utility model, comprises lever 1, piston fixed cover 5, relay piston 6 and needle 7; Described lever 1 comprises the connecting portion and the drive end 2 and the driven end 3 that are arranged on lever 1 two ends being arranged near lever 1 middle part; On described connecting portion, be provided with connecting hole 4; Described drive end 2 and driven end 3 are all spherical shape; Described relay piston 6 is slidably disposed in piston fixed cover 5; Described needle 7 is arranged on the front end of relay piston 6; The center line of described piston fixed cover 5, relay piston 6 and needle 7 is on same straight line; The sidepiece of described piston fixed cover 5 is provided with lever mouth 8; The sidepiece of described relay piston 6 is provided with driven slot 9, and driven slot 9 is arranged near on the position of lever mouth 8; Described driven end 3 passes lever mouth 8, and enters in lever slot 12.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The driven subassembly of the needle of present embodiment, drive end 2 and the driven end 3 of lever 1 are spherical shape, and therefore, in when work, the contact-making surface between driven end 3 and relay piston 6 is little, and friction is not lacked, easy to wear, fracture, and bulk strength is high, simple in structure, and cost is low; The driven end 3 of lever 1 drives relay piston 6 to slide along piston fixed cover 5, and needle 7 is followed relay piston 6 and moved reciprocatingly, and needle 7 can not produce skew, high 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.
