Description

Technical Field

[0001] This utility model belongs to the field of power communication, and specifically relates to a cable locking structure for a cable tower pole. Background Technology

[0002] A utility pole is a vertical pole-shaped structure that stands on the ground. It uses insulators, hardware and other accessories to fix conductors and form an overhead power line network. Its design must meet requirements such as mechanical strength, corrosion resistance and insulation performance to ensure stable operation of the line in complex environments.

[0003] Traditional cable locking structures typically rely on a single clamping method (such as direct clamping or single-time fixing). This design has obvious drawbacks: on the one hand, when subjected to external force or long-term vibration, the cable is prone to loosening or even falling off due to insecure fixing; on the other hand, the contact area between the flat clamping method and the curved outer wall of the cable is small, which can easily lead to local stress concentration and damage to the cable surface.

[0004] Therefore, existing cable locking structures suffer from problems such as easy loosening of single-layer fixing, insufficient locking strength, and small contact area that easily damages the cable. Utility Model Content

[0005] To overcome the problems of existing cable locking structures, such as easy loosening of single-layer fixing, insufficient locking strength, and easy damage to cables due to small contact area, a cable locking structure for cable stringing poles is proposed.

[0006] The technical solution of this utility model is as follows: a cable locking structure for a cable rack pole, including a fixed sleeve; and a rotating frame and a second sliding clamping block. A first sliding clamping block is slidably arranged inside the fixed sleeve. Two insertion slots are opened through the first sliding clamping block, and cables are wound in the two insertion slots. A first limiting rod is fixedly connected to the outer walls of the left and right ends of the first sliding clamping block. A rotating frame is rotatably arranged on the outer walls of the two ends of the fixed sleeve. An arc-shaped sliding groove is opened on the rotating frame, and the first limiting rod is placed in the arc-shaped sliding groove. A screw clamping component is arranged inside the first sliding clamping block.

[0007] Preferably, the upper and lower ends of the inner wall of the fixed sleeve are fixedly connected to limit strips, and the upper and lower ends of the outer wall of the first sliding clamping block are provided with limit grooves. The limit grooves and limit strips are adapted to each other, and the rear end of the fixed sleeve is provided with two arc-shaped clamping grooves.

[0008] Preferably, the outer wall of the fixed sleeve is fixedly connected to the left and right ends of the fixed column, and the rotating frame is rotatably mounted on the fixed column.

[0009] Preferably, the upper end of the rotating frame is provided with two bolts, and the bolts pass through the upper end of the rotating frame and the fixed sleeve and are threaded with nuts.

[0010] Preferably, an inner clamping block is fixedly connected to the rear end of the inner wall of the first sliding clamping block, and a fixing block is fixedly connected to the rear end of the first sliding clamping block. A first groove is opened through both the front and rear ends of the fixing block, and a fourth groove is opened through both the front and rear ends of the inner clamping block. A knob is rotatably provided on the inner clamping block, and a limiting block is fixedly connected to the outer wall of the fourth groove after the knob passes through the first limiting rod.

[0011] Preferably, the lead screw clamping component includes a second sliding clamping block and a second limiting rod. Two second limiting rods are fixedly connected to the front end of the inner clamping block. The second limiting rods are provided with second sliding clamping blocks. Second grooves are opened at the front and rear ends of the second sliding clamping block, and the second limiting rods are located in the second grooves.

[0012] Preferably, the front and rear ends of the second sliding clamping block are provided with threaded grooves, the rear end of the second sliding clamping block is provided with a third groove, the outer wall of the third groove fits with the arc-shaped outer wall of the cable, and the front end of the knob is fixedly connected with a threaded rod, the threaded rod and the threaded groove are threadedly connected.

[0013] The beneficial effects of this utility model are as follows: When the cable is passed through the two insertion slots, it is first initially clamped in the first sliding clamping block by the lead screw clamping component. Then, the rotating frame on the fixed sleeve is rotated, and the arc-shaped sliding groove rotates, thereby moving the two first limiting rods and the first sliding clamping block forward on the fixed sleeve. Then the rotating frame is fixed, thereby the cable is secondarily fixed and clamped by the fixed sleeve and the rear end groove of the insertion slot, which improves the clamping, fixing and locking strength of the cable.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-5 This utility model provides an embodiment of a cable locking structure for a cable rack pole, including a fixed sleeve 1; it also includes a rotating frame 103 and a second sliding clamping block 302. A first sliding clamping block 2 is slidably disposed within the fixed sleeve 1, and two insertion slots 202 are formed through the first sliding clamping block 2. Cables 6 are wound within the two insertion slots 202. First limiting rods 204 are fixedly connected to the outer walls of the left and right ends of the first sliding clamping block 2. The rotating frame 103 is rotatably disposed on the outer walls of both ends of the fixed sleeve 1, and an arc-shaped sliding groove 104 is formed on the rotating frame 103. The first limiting rods 204 are placed... Inside the arc-shaped groove 104, a screw clamping member is provided in the first sliding clamping block 2. When the cable 6 is passed through the two insertion slots 202, it is initially clamped in the first sliding clamping block 2 by the screw clamping member. Then, the rotating frame 103 on the fixed sleeve 1 is rotated, and the arc-shaped groove 104 rotates, thereby moving the two first limiting rods 204 to move the first sliding clamping block 2 forward on the fixed sleeve 1. Then, the rotating frame 103 is fixed, thereby the cable 6 is fixed and clamped a second time through the fixed sleeve 1 and the rear end groove of the insertion slot 202, which improves the clamping and locking strength of the cable 6.

[0022] Please see Figures 1-3In this embodiment, limiting strips 101 are fixedly connected to the upper and lower ends of the inner wall of the fixed sleeve 1, and limiting grooves 201 are formed on the outer walls of the upper and lower ends of the first sliding clamping block 2. The limiting grooves 201 and the limiting strips 101 are adapted to each other. Two arc-shaped clamping grooves 105 are formed at the rear end of the fixed sleeve 1, and the limiting strips 101 and the limiting grooves 201 are adapted to each other, which can improve the stability of the first sliding clamping block 2 sliding in the fixed sleeve 1. Fixed posts 102 are fixedly connected to the left and right ends of the outer wall of the fixed sleeve 1, and the rotating frame 103 is rotatably mounted on the fixed posts 102. During rotation, the rotating frame 103 moves around the axis of the fixed column 102. When the rotating frame 103 is pushed backward, the first sliding clamping block 2 will be displaced backward on the fixed sleeve 1. When the rotating frame 103 is pushed forward, the first sliding clamping block 2 will be displaced forward on the fixed sleeve 1. Two bolts 5 are provided at the upper end of the rotating frame 103. After the bolts 5 pass through the upper end of the rotating frame 103 and the fixed sleeve 1, a nut 501 is threaded on them. The rotation angle of the rotating frame 103 can be fixed by the bolts 5 and the nut 501.

[0023] Please see Figures 4-5 In this embodiment, an inner clamping block 3 is fixedly connected to the rear end of the inner wall of the first sliding clamping block 2, and a fixing block 203 is fixedly connected to the rear end of the first sliding clamping block 2. A first groove 205 is provided through both the front and rear ends of the fixing block 203. A fourth groove 306 is provided through both the front and rear ends of the inner clamping block 3. A knob 4 is rotatably mounted on the inner clamping block 3. After passing through the first limiting rod 204, the knob 4 is fixedly connected to the outer wall of the fourth groove 306 by a limiting block 401. The screw clamping component includes a second sliding clamping block 302 and a second limiting rod 301. Two second limiting rods 301 are fixedly connected to the front end of the inner clamping block 3. A second sliding clamping block 302 is provided on the second limiting rod 301. The front and rear ends of the second sliding clamping block 302 are provided with second grooves 303, and the second limiting rod 301 is located in the second groove 303. The front and rear ends of the second sliding clamping block 302 are provided with threaded grooves 304, and the rear end of the second sliding clamping block 302 is provided with a third groove 305. The outer wall of the third groove 305 fits against the arc-shaped outer wall of the cable 6. The front end of the knob 4 is fixed with a threaded rod 402. The threaded rod 402 and the threaded groove 304 are threadedly connected. By rotating the knob 4, the threaded rod 402 and the threaded groove 304 are threadedly connected, thereby driving the second sliding clamping block 302 to move backward under the limitation of the two second limiting rods 301, so that the two cables 6 are clamped by the third groove 305 in conjunction with the inner clamping block 3.

[0024] In use, firstly, pull the first sliding clamping block 2 on the fixing block 203 backward from the fixing sleeve 1 to expose the two insertion slots 202. Then, pass the cable 6 through the two insertion slots 202. Next, by rotating the knob 4, the threaded rod 402 and the threaded groove 304 are threadedly connected, thereby driving the second sliding clamping block 302 to move backward under the limitation of the two second limit rods 301. Thus, the two cables 6 are clamped by the third groove 305 in conjunction with the inner clamping block 3. Then, by flipping the rotating frame 103 forward, the arc-shaped sliding... The groove 104 drives the first limiting rod 204 to move forward to limit the movement, thereby causing the two first limiting rods 204 to drive the first sliding clamping block 2 to move forward. This causes the two cables 6 on the first sliding clamping block 2 to be secondary fixed by the clamping of the arc-shaped clamping groove 105 on the fixed sleeve 1 and the fixed block 203. Then, the bolt 5 is threaded through the rotating frame 103 and the fixed sleeve 1 and connected by the nut 501. The double-layer fixing method strengthens the locking structure of the cables 6 and can effectively prevent the cables 6 from falling off after fixing.
