Abstract
The invention discloses a pair of calipers for assembly and disassembly of M-shaped snap springs. The pair of calipers for assembly and disassembly of the M-shaped snap springs comprises a first caliper body and a second caliper body, wherein the first caliper body and the second caliper body are hinged to each other through a pin roll, one end of the first caliper body and a caliper head of the second caliper body are flat, the direction, parallel to the pin roll, of the caliper head is the height direction of the caliper head, the height of the caliper head is smaller than or equal to 8mm, and the thickness of the caliper head is smaller than or equal to 2mm. The pair of calipers for assembly and disassembly of the M-shaped snap springs has the advantages that the caliper head can be directly inserted into a hole of a socket of a suspension insulator, compression can be carried out on an M-shaped snap spring by clamping and compressing two elastic feet of the M-shaped snap spring, assembly and disassembly can be smoothly achieved, the speed is high, and the M-shaped snap spring cannot be damaged.
Description
Technical field
The present invention relates to a kind of specific purpose tool, be specially a kind of clamp of the M of loading and unloading shape jump ring.
Background technology
As shown in Figure 1, the shape of M shape jump ring 1 comprises main part 10, two elastic foots 12 and is positioned at elastic foot 12 free-ended crotches 11 as letter ' M '.As shown in Figure 2, M shape jump ring 1 is put into the hole 21 of the bowl 2 of suspension insulator, M shape jump ring 1 is squeezed, can be with producing corresponding elastic force, and two crotches 11 stretch out hole 21, be stuck on the wall of bowl 2.In the suspension insulator string of present 0.4kV-10kV transmission line of electricity, the such M shape jump ring 1 of a large amount of uses, when loading and unloading, just look for some article conveniently, for example bamboo chip, screwdriver, spanner etc., one people sets upright suspension insulator during operation, and another human bamboo chip etc. are aimed at M shape jump ring, and it is knocked.Its process wastes time and energy and is difficult for extracing.Article such as bamboo chip fracture easily, cause accidental injury; Screwdriver, spanner etc. are harder in addition, can make the distortion of M shape jump ring as misoperation, can't load and unload.The defective of prior art is, can not pluck quickly and unload M shape jump ring, needs two people operation, if misoperation can make the distortion of M shape jump ring use, causes waste.
Summary of the invention
At the above-mentioned defective that prior art exists, the problem to be solved in the present invention is, a kind of clamp of the M of loading and unloading shape jump ring are provided, and can load and unload M shape jump ring quickly and easily.
For addressing the above problem, the invention provides a kind of clamp of the M of loading and unloading shape jump ring, comprise first caliper and second caliper that are hinged by bearing pin, one end of described first caliper and the binding clip of second caliper are flat, the direction that described binding clip is parallel to described bearing pin is the short transverse of described binding clip, the height of described binding clip is less than or equal to 8mm, and the thickness of described binding clip is less than or equal to 2mm.
As preferably, described first caliper and second caliper are respectively equipped with relative catch surface at described binding clip with part between the described bearing pin, are formed for holding the hole clipping of hex bolts.
As preferably, the front end of described binding clip is provided with chamfering.
As preferably, described first caliper and second caliper are ferrous materials and make.
The clamp of loading and unloading of the present invention M shape jump ring have following beneficial effect: its binding clip can directly insert in the hole of bowl head of suspension insulator, by holding and compressing two elastic foots of M shape jump ring, make its compression, thereby realize loading and unloading smoothly, speed can be damaged M shape jump ring soon and not.
Description of drawings
Fig. 1 is the perspective view of M shape jump ring.
Fig. 2 for M shape jump ring pack into suspension insulator the bowl the time structural representation.
Fig. 3 is the perspective view of the clamp of loading and unloading M shape jump ring of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail, but not as a limitation of the invention.It is pointed out that following " front end ", with respect to the user, the end that caliper is used for holding articles is its front end.
As shown in Figure 3, the clamp 100 of the loading and unloading M shape jump ring of present embodiment, comprise first caliper 5 and second caliper 6 that are hinged by bearing pin 7, the front end of first caliper 5 is first binding clip 51, the front end of second caliper 6 is provided with second binding clip 61 corresponding with first binding clip 51, first binding clip 51 and second binding clip 61 are flat, as shown in Figure 3, the direction that is parallel to bearing pin 7 is the short transverse of first binding clip 51 and second binding clip 61, the height h of first binding clip 51 is less than or equal to 8mm, and thickness b is less than or equal to 2mm.Second binding clip 61 has the shape and size identical with first binding clip 51.The size design of first binding clip 51 and second binding clip 61 guarantees that it can insert in as shown in Figure 2 the M shape jump ring 1 and the slit 24 between the hole 21.
The use of clamp 100 of loading and unloading M shape jump ring of explanation present embodiment sees figures.1.and.2, first binding clip 51 of clamp 100 and second binding clip 61 are inserted respectively in as shown in Figure 2 the M shape jump ring 1 and the slit 24 between the hole 21, first binding clip 51 and second binding clip 61 compress M shape jump ring 1 respectively, make its compression, its crotch 11 is close mutually, break away from the state hold bowl 2, mobile clamp 100 can take out M shape jump ring 1.The process that M shape jump ring 1 is fit in the bowl 2 is similar with it, repeats no more.
By foregoing description as can be seen, use the clamp of the loading and unloading M shape jump ring of present embodiment a people to load and unload M shape jump ring rapidly, save time and manpower, can not economize on resources and fund as because prize M shape jump ring being damaged in the prior art during use.First caliper 5 and second caliper 6 of this bow compass can adopt ferrous materials to make, and be sturdy and durable, be difficult for being out of shape because external force is excessive, and with low cost, the scope of application is extensive.
As shown in Figure 3, as preferred version, in the present embodiment, the part of first caliper 5 between first binding clip 51 and bearing pin 7 is provided with first catch surface 41, similarly, second binding clip 62 of second caliper 6 and the part between the bearing pin 7 are provided with the second catch surface (not shown) relative with first catch surface 41, to be formed for holding the hole clipping 4 of hex bolts (not shown), are convenient to load and unload some little hex bolts.
As shown in Figure 3, the front end of first binding clip 51 and second binding clip 62 is provided with chamfering in the present embodiment, is convenient to insert in the hole 21 of bowl 2.
Certainly, the above is preferred embodiment of the present invention, should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also are considered as protection scope of the present invention.
