Description

Technical Field

[0001] This utility model relates to the field of cable support crossarm technology, specifically a cable support crossarm. Background Technology

[0002] A crossarm is generally an angle iron fixed horizontally at the top of a utility pole. It has porcelain insulators on it and is used to support overhead power lines. The installation of crossarms is carried out along with the installation of the utility pole. One or more crossarms can be installed on the same utility pole as needed.

[0003] The existing crossarm has a fixed length and cannot be changed according to the number of cables. Therefore, it is inconvenient to add cable locking devices to fix the cables, which reduces its practicality.

[0004] Therefore, it is particularly important to design a cable support crossarm to overcome the above-mentioned technical defects and improve overall practicality. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cable support crossarm includes a main crossbar. The main crossbar has grooves extending along its length on both its upper and lower sides. Support crossbars are slidably connected to the left and right ends of the main crossbar. Locking screws, which engage with the grooves, are provided on the upper and lower ends of the support crossbars facing the main crossbar. A wing nut is threaded onto the outer side of the locking screw, which passes through one end of the groove. Multiple sets of equally spaced positioning screw holes are provided on the top of both the main crossbar and the support crossbars. A clamp is installed on the rear side of the main crossbar. A positioning plate is provided on the top of both the main crossbar and the support crossbars. Assembly screws are provided on both the left and right sides of the positioning plate. A cable holder is provided on the top of the positioning plate, and a cable retainer is connected to the top of the cable holder.

[0008] As a preferred embodiment of this utility model, the internal structure size of the main crossbar is adapted to the external structure size of the support crossbar.

[0009] As a preferred embodiment of this utility model, the connection between the sliding groove and the locking screw is a sliding connection.

[0010] As a preferred embodiment of this utility model, the connection between the assembly screw and the positioning screw hole is a threaded connection.

[0011] As a preferred embodiment of this utility model, both ends of the cable retainer penetrate the bottom of the cable holder and are connected with nuts.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this utility model, a cable support crossarm is provided. The length of the crossarm can be adjusted according to the number of cables and installation requirements. The support crossarms on both sides inside the main crossarm are slid out. When the required length is reached, the locking screw is fixed inside the sliding groove using a wing nut. Then, multiple sets of positioning plates are installed on the positioning screw holes with assembly screws. Finally, the cable is placed in the cable holder and locked with cable clips and nuts, which increases the practicality and applicability of the crossarm. Attached Figure Description

[0023] A cable support crossarm includes a main crossbar 1. The main crossbar 1 has grooves 101 extending along its length on both the upper and lower sides of its front. Support crossbars 2 are slidably connected to both the left and right ends inside the main crossbar 1. Locking screws 201, which cooperate with the grooves 101, are provided on both the upper and lower ends of the support crossbar 2 and on the side facing the main crossbar 1. A wing nut 202 is threaded onto the outer side of one end of the locking screw 201, penetrating the groove 101. Multiple sets of equally spaced positioning screw holes 3 are provided at the top of both the main crossbar 1 and the support crossbar 2. A clamp 4 is installed on the rear side of the main crossbar 1. A positioning plate 5 is provided at the top of both the main crossbar 1 and the support crossbar 2. Assembly screws 501 are provided on both the left and right sides inside the positioning plate 5.
