The sealing ring is made of rubber, and the groove includes an upper groove and a lower groove. The upper groove is a groove located above the portion where the root of the bird thorn strip and the mounting hole are combined, and the lower groove is a groove located below the portion where the root of the bird thorn strip and the mounting hole are combined. The sealing ring is in an extruded state.

[0009] Furthermore, the expansion block is provided with longitudinal convex ridges around it, and the mounting hole is provided with concave strips matching with the convex ridges around it.

[0010] Furthermore, the bird thorn strip also includes a steel wire strip in the middle, and the expansion block has a middle hole in the middle for inserting the steel wire strip, and the steel wire strip is inserted into the middle hole for connection, and the steel wire strip and the middle hole are interference fit.

[0011] The beneficial effect of the utility model is that the bird thorn for the power system has the advantages that the bird thorn strip will not loosen after long-term use and the use effect is guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described below in conjunction with the embodiments.

[0017] like Figure 1 , 2 As shown in , 3, a bird thorn for electric power equipment comprises a buckle 1, a mounting seat 2 and a plurality of bird thorn strips 3, wherein the buckle is a fixture mounted on the electrical equipment, the mounting seat is mounted on the buckle, the mounting seat is a hemispherical shell, the mounting seat has a mounting hole 21 for plugging the root of the bird thorn strip; the roots of the plurality of bird thorn strips are mounted in the mounting holes of the mounting seat; the characteristic is that the root of the bird thorn strip has an expansion block 31, the expansion block has a thicker structure close to the bottom surface of the root of the bird thorn strip, and the expansion block and the mounting hole are interference fit.

[0018] Due to the above arrangement, the utility model can install the bird thorn strip more firmly, thereby achieving the purpose of the utility model.

[0019] During installation, the bird thorn strip can be passed through the mounting hole from below, and the bottom of the bird thorn strip can be hit upward with a hammer to make the expansion block and the mounting hole interference fit, so that the bird thorn strip can be installed more firmly.

[0020] In one embodiment, the expansion block is a terrace-shaped structure.

[0021] In another embodiment, the trapezoidal structure includes a truncated cone-shaped structure and a prism-shaped structure.

[0022] Furthermore, the portion where the root of the bird thorn strip and the mounting hole are combined has a groove 4 for accommodating a sealing ring, and a sealing ring 5 is installed in the groove. The sealing ring is made of rubber, and the groove includes an upper groove 41 and a lower groove 42. The upper groove is a groove located above the portion where the root of the bird thorn strip and the mounting hole are combined, and the lower groove is a groove located below the portion where the root of the bird thorn strip and the mounting hole are combined. The sealing ring is in an extruded state.

[0023] Of course, the upper groove 41 and the lower groove 42 are respectively installed with sealing rings.

[0024] The utility model is arranged in this way, and rainwater can be reduced between the root of the bird thorn strip and the joint of the mounting hole, so the utility model is safer to use and has the advantages of extending the service life.

[0025] Furthermore, there are longitudinal convex ridges 311 around the expansion block, and there are concave strips 211 matching the convex ridges around the mounting hole.

[0026] The utility model is arranged in this way, and the rotation of the bird thorn strip can also be prevented.

[0027] Furthermore, the bird thorn strip also includes a steel wire strip 32 in the middle, and the expansion block has a middle hole in the middle for inserting the steel wire strip. The steel wire strip is inserted into the middle hole for connection, and the steel wire strip and the middle hole are interference fit.

[0028] The utility model is arranged in this way, and can also save costs, because the manufacturing cost is lower, and it also has the advantage that the bird thorn strips are installed more firmly.
