Abstract
The utility model relates to a round-head lever. The round-head lever comprises a lever body which comprises a connecting part, a driving end and a driven end, wherein the connecting part is arranged close to the middle part of the lever body, the driving end and the driven end are arranged at the two ends of the lever body, a connecting hole is formed in the connecting part, and the sections of the driving end and driven end are circular arc-shaped. According to the round-head lever disclosed by the utility model, the sections of the driving end and driven end are circular arc-shaped, so that during work of the round-head lever, the contact area between the driving end and a driving piece, and the contact area between the driven end and a driven piece are small, the friction is slight, and thus the lever cannot be broken, the overall strength is high, the structure is simple and the cost is low.
Description
Technical field
The utility model relates to a kind of control lever of needle, particularly a kind of simple in structure, intensity is high, the round end lever of long service life, belongs to TOP-TIP component technology field.
Background technology
The drive end of the control lever of existing needle and driven end are forked, and drive end is connected with driving link by pin, and driven end is connected with needle by straight pin; The lever of this structure, the intensity of the equal bifurcation structure of drive end and driven end is lower, lever in the time of work, end easy fracture, and bifurcation structure is comparatively complicated, processing cost is high.
Utility model content
The utility model object be provide in order to overcome the deficiencies in the prior art a kind of simple in structure, intensity is high, the round end lever of long service life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of round end lever, comprises lever body; Described lever body comprises the connecting portion and the drive end and the driven end that are arranged on lever body two ends that are arranged near lever body middle part; On described connecting portion, be provided with connecting hole; The cross section of described drive end and driven end is circular-arc.
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 round end lever of the utility model scheme, drive end and driven end cross section are circular-arc, therefore,, in the time of work, the contact-making surface between drive end and driven end and driving link and driven member is little, friction is few, can not fracture, bulk strength is high, simple in structure, cost is low, can further reduce contact area if drive end and driven end are designed to spherical shape.
Brief description of the drawings
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the schematic diagram of round end lever described in the utility model;
Accompanying drawing 2 is the schematic diagram of a kind of embodiment of round end lever described in the utility model;
Wherein: 1, lever body; 2, drive end; 3, driven end; 4, connecting hole; 5, driving link; 6, driven member; 7, needle.
Detailed description of the invention
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 round end lever described in the utility model, comprises lever body 1; Described lever body 1 comprises the connecting portion and the drive end 2 and the driven end 3 that are arranged on lever body 1 two ends that are arranged near lever body 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.
As shown in Figure 2, described drive end 2 places are provided with driving link 5, and driven end 3 places are provided with driven member 6; Described driving link 5 is a piston, and drive end 2 is arranged in the link slot of driving link 5; Described driven member 6 is a piston component, and driven end 3 is arranged in the link slot of driven member 6; The front end of described driven member 6 is provided with needle 7; In the time that driving link 5 moves, lever body 1 utilizes lever principle to drive driven member 6 to move, and then makes driven member 6 drive valve needle movements.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The round end lever of present embodiment, drive end 2 and driven end 3 are designed to spherical shape, and therefore, in the time of work, the contact-making surface between drive end 2 and driven end 3 and driving link 5 and driven member 6 is little, and friction is few, can not 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.
