Abstract
The utility model relates to a power component for a valve needle. The power component comprises a lever and a power piston, wherein the lever comprises a connecting part which is near the middle part of the lever, a driving end and a driven end, the driving end and the driven end are arranged at the two ends of the lever, a connecting hole is formed in the connecting part, the cross sections of the driving end and the driven end are in an arc shape, a lever groove is formed in the side part of the power piston, and the driving end is arranged in the lever groove. When the power component for the valve needle works, as the cross sections of the driving end and the driven end are in the arc shape, 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.
Description
Technical field
The utility model relates to the assembly of the needle in a kind of TOP-TIP, and particularly the Power Component 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 Power Component of existing needle is comprised of lever and power piston, and the drive end of lever and driven end are forked, and drive end is connected with driving link by pin; The Power Component of this structure, the intensity of the bifurcation structure that the drive end of lever and driven end are equal is lower, and lever is when work, end easy fracture, the contact-making surface between drive end, pin and power piston 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 Power Component 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 Power Component of needle, comprises lever and power piston; 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; The sidepiece of described power piston is provided with lever slot; Described drive end is arranged 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 Power Component of the needle of the utility model scheme, the drive end of lever and driven end cross section are circular-arc, therefore,, when work, the contact-making surface between drive end and power piston is little, friction is few, not easy to wear, fracture, bulk strength is high, simple in structure, cost is low, if drive end and driven end are designed to spherical shape, can further reduce contact area.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
The schematic diagram of the Power Component that accompanying drawing 1 is needle described in the utility model;
Wherein: 1, lever; 2, drive end; 3, driven end; 4, connecting hole; 11, power piston; 12, lever 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 Power Component of a kind of needle described in the utility model, comprises lever 1 and power piston 11; 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; The sidepiece of described power piston 11 is provided with lever slot 12; Described drive end 2 is arranged in lever slot 12.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The Power Component 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 drive end 2 and power piston 11 is little, and friction is not lacked, easy to wear, fracture, and bulk strength is high, simple in structure, and cost is low.
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.
