Abstract
The invention discloses a lifting clamp, which comprises a square open frame. The lifting clamp is characterized in that a connecting shaft is arranged in the center of the sealed end of the frame, and is connected with the frame through a thread, wherein a disk is arranged at the lower end of the connecting shaft; an elastic rod is connected to the lower end of the disk. The lifting clamp further comprises a frame pressure rod connected with the connecting shaft, wherein the frame pressure rod penetrates through the sealed end of the frame; the open end of the frame pressure rod is propped against the elastic rod; the distance of the open end of the frame pressure rod is smaller than the distance between the frame pressure rod and the connecting end of the connecting shaft. According to the lifting clamp, a function of self-locking during lifting is realized, and locking force in a locking process can be strengthened to prevent loosening.
Description
Technical field
The present invention relates to workpiece accessory field, point out a kind of hanging clamp especially.
Background technology
The fixture being conventionally used to lifting is generally unidirectional self-lock or adopts motor assist locking, easily cause coupling mechanism force inadequate by unidirectional self-lock, the situation that workpiece comes off may be there is, and although motor assist locking can provide actv. coupling mechanism force, but add more operation in operation, operation becomes trouble, therefore needs a kind of hanging clamp, namely realize self-locking, ensure that again it has enough coupling mechanism forces.
Summary of the invention
The object of the invention is to propose a kind of hanging clamp, achieve the function of self-locking in lifting on the one hand, the coupling mechanism force in locking process can be increased on the other hand, prevent to loosen.
The technical scheme realizing the object of the invention is as follows:
Hanging clamp, comprise square aperture framework, the closed end center of described framework is provided with adapter shaft, described adapter shaft is connected with framework by screw thread, and the lower end of adapter shaft is provided with disk, and described disk lower end connects elastic rod, also comprise the framework depression bar be connected with adapter shaft, described framework depression bar penetrates the closed end of framework, and open end and elastic rod offset, and the spacing of described framework depression bar open end is less than the distance of itself and adapter shaft coupling end.
Further, described framework both sides are also provided with live splint, and described live splint is connected with framework by bearing, are connected inside it by the bottom of pipe link with framework depression bar.
Further, bottom formation and the live splint body of described live splint are the clip of 90 °.
After adopting said structure, the invention has the beneficial effects as follows: the structure of described framework depression bar is the distance that the spacing of open end is less than itself and adapter shaft coupling end, rotating frame depression bar, when framework depression bar moves up, press elastic rod on the one hand close in opposite directions, make elastic rod form coupling mechanism force to the upper end of workpiece, drive live splint close in opposite directions on the other hand, make live splint form coupling mechanism force to the side of workpiece;
Be rotationally connected axle, move on elastic rod, make live splint and framework depression bar form coupling mechanism force to workpiece;
Two kinds of different occupation modes, can form the coupling mechanism force of diverse location, have practicality to workpiece.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in Figure 1, hanging clamp, comprise square aperture framework 1, the closed end center of described framework 1 is provided with adapter shaft 2, and described adapter shaft 2 is connected with framework 1 by screw thread, the lower end of adapter shaft 2 is provided with disk 3, described disk 3 lower end connects elastic rod 4, and also comprise the framework depression bar 5 be connected with adapter shaft 2, described framework depression bar 5 penetrates the closed end of framework 1, and open end and elastic rod 4 offset, the spacing of described framework depression bar 5 open end is less than the distance of itself and adapter shaft 2 coupling end.
Described framework 1 both sides are also provided with live splint 6, and described live splint 6 is connected with framework 1 by bearing 7, are connected inside it by pipe link 8 with the bottom of framework depression bar 5.
Bottom formation and live splint 6 body of described live splint 6 are the clip 8 of 90 °.
Occupation mode one:
Rotating frame depression bar, the structure of described framework depression bar is the spacing of the open end distance that is less than itself and adapter shaft coupling end when framework depression bar moves up, press elastic rod on the one hand close in opposite directions, elastic rod is made to form coupling mechanism force to the upper end of workpiece, drive live splint close in opposite directions on the other hand, make live splint form coupling mechanism force to the side of workpiece;
Occupation mode two:
Be rotationally connected axle, move on elastic rod, make live splint and framework depression bar form coupling mechanism force to workpiece.
