Furthermore, the hollowed-out structure is two mutually crossed support ribs, and the thickness of each support rib is half of the wall thickness.

Further, the inside honeycomb holes structure that is equipped with of lower plate, a plurality of honeycomb holes run through in both sides around the lower plate.

Further, the lower end of the lower clamping plate is also provided with a groove for limiting the rotation of the bolt head of the fastening bolt.

Furthermore, metal reinforcing sheets are arranged on two side walls of the groove.

Furthermore, a gasket strip is arranged between the fastening bolt and the upper clamping plate, a gasket strip hole is formed in the gasket strip, and the fastening bolt penetrates through the gasket strip hole to enter the long hole.

Furthermore, the upper clamping plate and the lower clamping plate are made of rubber materials.

The utility model discloses an useful part lies in:

the deformable structure is arranged in the upper clamp plate and the lower clamp plate, the deformable structure of the upper clamp plate is a hollow structure inside the upper clamp plate, the deformation amount of the hollow structure can change along with the change of the diameter of a cable, the deformable structure of the lower clamp plate is a honeycomb hole structure inside the lower clamp plate, the strength of the lower clamp plate can be guaranteed by the honeycomb hole structure, and the lower clamp plate can have the deformation amount. The upper and lower splint centre gripping to the cable each other, and in the use, the cable diameter changes, perhaps the fastener itself takes place to shrink, and upper and lower splint can both the automatic adjustment adaptation to ensure the effective centre gripping to the cable.

Drawings

Fig. 1 is a schematic structural view of the clamping portion of the elastic wire clamp of the present invention.

Reference numerals: the clamping device comprises an upper clamping plate 1, a lower clamping plate 2, a hollow structure 3, a supporting rib 4, a honeycomb hole structure 5, a fastening bolt head 6, a metal reinforcing sheet 7 and a filler strip 8.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to fig. 1 in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

The utility model provides an elastic wire clamp, includes punch holder, lower plate and fastening bolt, the both sides of punch holder are equipped with the last clamping part that is used for the centre gripping cable, be equipped with the slot hole in the middle of two punch holders, the both sides of lower plate are equipped with the lower clamping part that is used for the centre gripping cable, be mounting plane in the middle of two lower clamping parts, the last bolt mounting hole that is equipped with of mounting plane, fastening bolt passes the slot hole of punch holder and the bolt mounting hole and the nut cooperation of lower plate and compresses tightly punch holder and lower plate, the inside hollow out construction that is of punch holder.

The supporting ribs are arranged in the hollow structure, the two supporting ribs are mutually crossed, one end of each supporting rib is connected to the upper inner wall of the hollow structure, and the other end of each supporting rib is connected to the lower inner wall of the hollow structure. When the fastening bolt is fastened downwards, the hollow structure has certain deformation amount while maintaining the firmness.

The lower plate is inside to be honeycomb holes structure, and honeycomb holes structure includes the tiny through-hole of a plurality of, and these through-holes run through both ends around the lower plate, and under the normal condition, the lower plate size is less than the punch holder size, receiving the condition of equal pressure, and the firmness that just requires lower plate is higher than the punch holder more, but will keep the lower plate to have certain deformation volume, consequently adopts honeycomb holes structure, is applicable to the lower plate more.

The preferred material of punch holder and lower plate is the rubber material, and rubber is more operable to the moulding plastics of various shapes, and rubber self is the insulator moreover, can be applicable to high tension cable.

The lower extreme of lower plate is equipped with the pivoted recess of restriction fastening bolt head, and fastening bolt passes the fastening hole of punch holder and lower plate, and the bolt head card is in the recess, and the bolt head is regular hexagon usually, and its two parallel face cards no longer rotate in the recess, because in the installation, the fastening force of bolt is great, for avoiding the bolt head to damage the recess, consequently, has still set up the metal on the both sides plane of recess and has strengthened the piece.

It is obvious to a person skilled in the art that the invention is not limited to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention, and that the embodiments are therefore to be considered in all respects as exemplary and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
