Detailed Description

For the purpose of further illustrating the various embodiments, the present utility model provides the accompanying drawings, which are a part of the disclosure of the present utility model, and which are mainly used to illustrate the embodiments and, together with the description, serve to explain the principles of the embodiments, and with reference to these descriptions, one skilled in the art will recognize other possible implementations and advantages of the present utility model, wherein elements are not drawn to scale, and like reference numerals are generally used to designate like elements.

According to an embodiment of the utility model, an improved bolt-type strain clamp is provided.

Embodiment one:

as shown in fig. 1-2, an improved bolt type strain clamp comprises a clamp body 1 and a hanging ring 2 arranged on the clamp body 1, wherein a jacket 3 with an arc semicircular structure is arranged at the inner upper part of the clamp body 1, a fastening pad 4 is attached to the inner wall of the jacket 3, elastic connecting rods 5 are fixedly connected to the middle parts of two inner cambered surfaces of the jacket 3, through grooves 6 are formed in the bent walls in the upper part of the clamp body 1, the other ends of the two elastic connecting rods 5 penetrate through the through grooves 6 and are fixedly connected with clamping rods 7, hooks 8 with arc structures are arranged in the hanging ring 2, and the clamping rods 7 are clamped into the hooks 8;

embodiment two:

the wire inlet and outlet notch of the wire clamp body 1 is of an arc-shaped structure, and the wall surfaces of the wire inlet and outlet notch of the existing bolt type strain clamp are all plane, so that the surface of a wire can be scratched with the right angle of the wire inlet and outlet notch of the bolt type strain clamp, and damage occurs;

the fastening pad 4 is made of rubber;

the diameter of the clamping rod 7 is larger than the width of the through groove 6, so that the clamping rod 7 cannot penetrate through the through groove 6;

the working principle of the utility model is as follows:

after the wire clamp body 1 passes through the wire, the U-shaped bolt is firstly screwed, and then the clamping rod 7 is pulled, so that the clamping sleeve 3 compresses the wire until the clamping rod 7 is clamped on the hook 8 in the hanging ring 2, at the moment, the clamping sleeve 3 and the fastening pad 4 fasten the wire at the wire outlet notch of the wire clamp body 1 together, the U-shaped bolt fastens the wire at the wire inlet notch of the wire clamp body 1, and the clamping sleeve 3 and the fastening pad 4 fasten the wire at the wire outlet notch of the wire clamp body 1, so that the tightness of the wire is enhanced;

therefore, after the U-shaped bolt is screwed, the clamping rod 7 is pulled, so that the clamping sleeve 3 compresses the wire, and then the clamping rod 7 is clamped into the hook 8 to fasten the wire of the wire outlet notch of the wire clamp body 1, thereby achieving the effect of auxiliary fastening, and further improving the tightness of the wire in the bolt-type strain clamp.
