Abstract

The invention discloses a novel toggle clamp, which belongs to the field of machinery. The novel toggle clamp comprises a base, an operating lever, a linkage rod, a push rod, and a copper bush, wherein a bending part of the operating lever is pin-jointed with one end of the linkage rod, and the other end of the operating lever is pin-jointed with the push rod; the push rod runs through the base; the copper bush is arranged at the front end inside the base and is contacted with the push rod; the inner edge of the copper bush is provided with a groove; and the outer edge of the front end of the base is provided with an external thread and a nut matched with the external thread. The novel toggle clamp has the advantages that: the phenomenon that molten slag is formed on the push rod due to the spark produced by short circuit caused by careless operation when a user performs electric welding can be prevented, the service life of a toggle clamp structure is prolonged, the situation that the precision of the conventional toggle clamp structure is reduced because the molten slag is formed on the push rod is improved, and lubricating oil is easy to stay in the groove of the copper bush.

Description

A kind of novel toggle clamp

Technical field

The present invention relates to a kind of toggle clamp, specifically is a kind of novel toggle clamp, belongs to mechanical field.

Background technology

When people use toggle clamp, earlier each working substance on the platform will be fixed with the toggle clamp structure, electric welding in addition again, if accidentally electrode holder is touched mutually with clamp, promptly can pass through fast because of short circuit causes big electric current, and on the push rod of closely spaced position such as toggle clamp, produce spark, this existing picture easily causes spark place generation melting slag, and cause the push rod of toggle clamp can't be movable, needing that this is melted slag this moment removes, in the course of time not only can cause the clamping precision of toggle clamp to descend, and bring great inconvenience for people's use.

Summary of the invention

Problem at above-mentioned prior art exists the invention provides a kind of novel toggle clamp, is provided with copper sheathing, prevents that the user from forming on push rod and melt slag because of short circuit produces spark accidentally when electric welding.

To achieve these goals, the technical solution used in the present invention is: a kind of novel toggle clamp, comprise pedestal, action bars, trace and push rod, one end of the kink of described action bars and trace is articulated, and the other end then articulates push rod, and described push rod runs through pedestal, also comprise copper sheathing, the inboard front end of described pedestal is provided with copper sheathing and contacts with push rod, and described copper sheathing inner edge is provided with groove, the nut that described pedestal front outer is provided with external screw thread and matches.

As preferably, short end place of described action bars and pedestal are articulated.

As preferably, described pedestal rear end is provided with lug, and the place is articulated with the short end of action bars.

The invention has the beneficial effects as follows: can prevent that the user from forming and melt slag because of short circuit produces spark accidentally when electric welding on push rod, increase the service life of toggle clamp structure, improved existing toggle clamp structure and melted slag and cause toggle clamp precise structure degree to subtract poor situation because of forming on the push rod, lubricating oil easily is detained in the copper sheathing groove.

The specific embodiment

The invention will be further described below in conjunction with accompanying drawing.

As depicted in figs. 1 and 2, the present invention includes hollow base 10 and action bars 20, one end of the kink of described action bars 20 and trace 30 is articulated, the other end then articulates push rod 40, described push rod 40 runs through pedestal 10, described pedestal 10 inboard front ends are provided with copper sheathing 50 and contact with push rod 40, described copper sheathing 50 inner edges are provided with groove 51, the nut 15 that described pedestal 10 front outers are provided with external screw thread 14 and match, described action bars 20 short end places and pedestal 10 are articulated, described pedestal 10 rear ends are provided with a

lug

60, and 20 short end places are articulated with action bars.

Described pedestal 10 rear ends are provided with two cross-sectional grooves 11, can for action bars 20 ccontaining with stir, the front outer of pedestal is provided with an external screw thread 14 and a nut 15, pedestal is fixed on the pedestal, copper sheathing 50 is located at pedestal 10 inboard front ends, the inner edge of this copper sheathing is provided with groove 51, the place, two ends of the rear side of this pedestal 10 is provided with perforation 12, be pivoted with a L shaped action bars 20, hold perforation 23 21 on to be pivoted through the perforation 12 of pedestal 10 with the short of this action bars 20 with latch 13, the kink of this action bars 20 is provided with a perforation 24 and is provided with an inside groove 26, can supply the end institute of trace 30 ccontaining, the perforation 24 of kink is articulated with latch 25 with the perforation 31 of trace 30, the perforation 41 that the other end of trace 30 is provided with on another perforation 32 and the push rod 40 is articulated with latch 43, push rod also is provided with a profile groove 42, can be ccontaining for the other end of trace 30, and push rod 40 passes pedestal 10.

When the user operates, when action bars 20 is stirred, can spur trace 20 forward, along pedestal 10 direction displacements, push rod 40 is pushed against forward push rod 40, clip working substance; When the user needs the electric welder crop, utilize each target of each toggle clamp structure clamping desire welding of being fixed on the workbench earlier, negative pole with electric welding machine connects mutually with workbench earlier, positive pole then is connected on the electrode holder and welds, if during user's electric welding, accidentally electrode holder is contacted with workbench, then can be because of short circuit, and less gap location produces spark between workpiece and anchor clamps, contact with push rod 40 because of being equipped with a copper sheathing 50 in the pedestal 10, can utilize the preferable characteristic of electric conductivity of copper, just can be on push rod 40 and pedestal 10 or target form and not melt slag because of short circuit produces spark, can prevent that throw-out lever 40 surfaces melt the smooth and easy situation that slag hinders displacement because of formation and produce, the inner edge of copper sheathing 50 be provided with groove 51, lubricating oil easily is detained in groove 51, makes quiet and smooth-going more the moving of push rod 40.

As shown in Figure 3,, can be provided with a lug 60 at the rear of pedestal 10 and hold 21 to be articulated, and install a copper sheathing 50, can reach identical functions with pedestal 10 front end inboards with the short of action bars 20 as another kind of embodiment; Copper sheathing 50 can substitute by a plastic-steel material in addition, utilizes the insulation of plastic-steel material and heat-resisting characteristic, also can prevent forming on the throw-out lever melting slag.
