Abstract

A double-face insection lock washer for a dropper wire clamp comprises a bowl-shaped body, the periphery of the bowl-shaped body is connected with a fixing double-lug and a locking single-lug, the end of the fixing double-lug is bent by 90 degrees towards the concave side of the bowl-shaped body, and the width of an opening formed after the fixing double-lug is bent is slightly larger than that of a dropper wire clamp body used in cooperation with the fixing double-lug. The single stop lug is perpendicular to the double fixed lugs and is bent towards the convex side of the bowl-shaped body, and insections are arranged on the upper surface and the lower surface of the bowl-shaped body. Technical characteristics of an existing lock washer and an existing insection disc spring washer are integrated into a whole, the number of parts is reduced, installation steps are simplified, production, use and maintenance cost is reduced, and meanwhile the requirement for the length of a bolt is lowered.

Description

TECHNICAL FIELD

[0001] The utility model relates to fastener technical field especially relates to a double -sided tooth pattern stop washer for pendant wire clamp. BACKGROUND

[0002] In the existing simplified overhead contact system parts, the contact line pendant wire clamp uses bolt, nut, stop washer to connect and assemble, in order to solve the problem of unqualified sliding load of contact line pendant wire clamp, the existing technology adopts the installation tooth pattern disc spring washer between stop washer and mounting nut to solve the above problem, but after increasing tooth pattern disc spring washer, the problem of insufficient bolt head appears again, at the same time, the increase of fastener types and quantity not only increases cost, but also makes operation more complicated when installing and disassembling, and is more likely to be lost. SUMMARY

[0003] In order to solve the above problems in the prior art, the utility model provides a double -sided tooth pattern stop washer for pendant wire clamp.

[0004] The utility model discloses a double -sided tooth pattern stop washer for pendant wire clamp, characterized by including bowl -shaped body, the bowl -shaped body periphery is connected with fixed double -ear and stop single -ear, the fixed double -ear end department is towards the bowl -shaped body concave side bending 90 degrees, and the opening width after bending is slightly greater than the width of the pendant wire clamp body matched with it, the stop single -ear is perpendicular to the fixed double -ear arrangement and is bent towards the bowl -shaped body convex side, and the upper and lower surfaces of the bowl -shaped body all have tooth pattern.

[0005] Further, the cross section of the tooth pattern is triangular and uniformly distributed radially.

[0006] Further, the fixed double -ear is radially symmetric, and the stop single -ear is located at the middle position of the fixed double -ear.

[0007] Further, the stop single -ear is symmetrically provided with an arc-shaped notch on both sides of the connection with the bowl -shaped body.

[0008] The utility model has the advantages of:

[0009] 1, the washer body is bowl -shaped, and elastic deformation is generated after compression, so that the axial force of the nut and bolt fastening can be increased, the bowl -shaped concave surface and convex surface are provided with tooth pattern, and the friction of the contact surface is increased, the technical characteristics of the existing stop washer and the existing tooth pattern disc spring washer are integrated, the number of parts is reduced, the installation steps are simplified, and the production, use and maintenance cost is reduced, at the same time, the reduction of the number of fasteners also reduces the length requirement of the bolt, so that the bolt used in the prior art can meet the length requirement of the head, and the bolt specification does not need to be replaced.

[0010] 2, the utility model discloses fixed double-ear end opening width and the matching use of hanging string line clamp body width adaptation, need not on -the -spot bending, improve the overhead contact system high altitude operation efficiency and security.

[0011] 3, the utility model discloses the stop single ear towards bowl body convex side bending, and its root both sides symmetrical arrangement has the arc gap, makes stop single ear in high altitude bending more convenient and fast, more suitable for overhead contact system high altitude operation.
