Description

Technical Field

[0001] This utility model relates to the field of cable protection technology, and in particular to a high-toughness, impact-resistant cable protection pipe. Background Technology

[0002] Cable protection pipes are metal protective pipes with a certain mechanical strength that are laid on the outer layer of cables to prevent them from being damaged.

[0003] Cable protection pipes are mainly installed at the intersection of communication cables and power lines to prevent short circuit accidents caused by power line breakage, which could cause the communication cables and steel wire ropes to become energized, thus protecting the cables, switches, core boards, and even the entire machine from being burned out. They also play a certain role in isolating the magnetic field interference of power lines.

[0004] Most existing cable protection pipes are integrally formed pipes. When protecting cables, the cable needs to be inserted from one end of the protection pipe and pulled out from the other end to achieve the normal protection effect. The whole process is time-consuming and laborious, which is not conducive to improving work efficiency. At the same time, when the cable needs to be replaced or maintained, the integrally formed protection pipe is even more inconvenient. In order to solve the above problems and defects, there is an urgent need for a high-toughness and impact-resistant cable protection pipe. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a high-toughness and impact-resistant cable protection pipe to solve the problem that most existing cable protection pipes are one-piece molded pipes. When protecting cables, it is necessary to insert the cable from one end of the protection pipe and pull it out from the other end in order to achieve a normal protective effect on the cable. The whole process is time-consuming and laborious, which is not conducive to improving work efficiency. At the same time, the one-piece molded protection pipe is even more inconvenient when the cable needs to be replaced or maintained.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A high-toughness, impact-resistant cable protection tube includes: a first protection tube and a second protection tube; the first protection tube has a square groove at its bottom, a circular groove on the inner wall of the square groove, a spring fixedly mounted on the inner wall of the circular groove, a connecting block fixedly mounted on the end of the spring away from the circular groove, a locking block fixedly mounted on the end of the connecting block away from the spring, a fixing pin engaged on the side of the locking block away from the connecting block, the bottom of the fixing pin being fixedly connected to the second protection tube, a rotating shaft rotatably connected to the top of the first protection tube, a connecting rope fixedly connected to the outer wall of the rotating shaft, and a connecting rope fixedly connected to the end of the connecting rope away from the rotating shaft being fixedly connected to the connecting block.

[0008] Preferably, a knob is fixedly mounted on the top of the rotating shaft.

[0009] Preferably, both the outer walls of the first protective tube and the second protective tube are fixedly fitted with stabilizing supports, and the cross-sectional shape of the stabilizing supports is "L".

[0010] Preferably, the inner walls of both the first and second protective tubes are fixedly fitted with a second spring, and the end of the second spring is fixedly fitted with a protective ring.

[0011] Preferably, the number of spring 1, connecting block, locking block, fixing pin and connecting rope is two sets, and the two sets of spring 1, connecting block, locking block, fixing pin and connecting rope are symmetrically distributed on both sides of the rotating shaft.

[0012] Preferably, the cross-sectional shape of the card block is a right trapezoid, and the hypotenuse of the card block is located on the side closer to the fixing pin.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects:

[0014] 1. In the above scheme, the cable is placed on the top of the inner wall of the second protective tube, and then the first protective tube and the second protective tube are connected. When the fixing pin at the top of the second protective tube is inserted into the square groove, the locking block is squeezed by the fixing pin. The locking block and the connecting block move into the depth of the round groove. When the fixing pin is fully inserted into the square groove, the locking block is no longer squeezed. The connecting block and the locking block are pushed to the position of the fixing pin by the first spring until they are locked and fixed with the fixing pin. When the cable needs to be maintained, it is only necessary to rotate the shaft. The rotation of the shaft drives the connecting rope to wrap around the outer wall of the shaft. Then, the connecting rope pulls the connecting block and the locking block into the depth of the round groove, so that the locking block separates from the fixing pin. This can separate the first protective tube and the second protective tube, which is conducive to improving the convenience of disassembling and assembling the first protective tube and the second protective tube, and ensuring the protection and maintenance effect of the cable.

[0015] 2. In the above scheme, by setting spring two and protective ring, it is beneficial for spring two to reduce the pressure when protective tube one and protective tube two are subjected to pressure, thereby improving the protection effect on the cable. Attached Figure Description

[0024] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of this utility model. However, this is only for illustrative purposes and is not intended to limit this utility model to the specific structure, device and environment. According to specific needs, those skilled in the art can adjust or modify these devices and environments, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0025] The high-toughness, impact-resistant cable protection pipe provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are listed as best and preferred embodiments; other alternative methods may be used by those skilled in the art. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0026] like Figure 1 , Figure 2 and Figure 4As shown, an embodiment of this utility model provides a high-toughness, impact-resistant cable protection tube, including: a first protection tube 1 and a second protection tube 2, both of which are semi-circular tubes; a square groove 101 is formed at the bottom of the first protection tube 1, and a circular groove 102 is formed on the inner wall of the square groove 101. A spring 103 providing elastic force is fixedly installed on the inner wall of the circular groove 102. A connecting block 104 is fixedly installed at the end of the spring 103 away from the circular groove 102, and a locking block 105 is fixedly installed at the end of the connecting block 104 away from the spring 103. A fixing pin 106 is snapped onto one side of the connecting block 104. The bottom of the fixing pin 106 is fixedly connected to the second protective tube 2. A rotating shaft 107 is rotatably connected to the top of the first protective tube 1. A connecting rope 108 is fixedly connected to the outer wall of the rotating shaft 107. The end of the connecting rope 108 away from the rotating shaft 107 is fixedly connected to the connecting block 104. The cross-sectional shape of the locking block 105 is a right trapezoid. The hypotenuse of the locking block 105 is located on the side close to the fixing pin 106. By limiting the locking block 105, it is beneficial to improve the smoothness of the connection and fixation between the fixing pin 106 and the locking block 105.

[0027] like Figure 2 and Figure 4 As shown, a knob 109 is fixedly mounted on the top of the rotating shaft 107. By setting the knob 109, it is convenient to drive the rotating shaft 107 to rotate by rotating the knob 109, thereby improving the convenience of rotating the rotating shaft 107.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, both the outer walls of the first protective tube 1 and the second protective tube 2 are fixedly equipped with stabilizing supports 110. The cross-sectional shape of the stabilizing supports 110 is "L". By setting the stabilizing supports 110, the stability of the device during protection is improved, and the device is prevented from rolling during protection, which could cause the cable to twist and damage the cable.

[0029] like Figure 3 As shown, spring 111 is fixedly installed on the inner wall of both protective tube 1 and protective tube 2. A protective ring 112 is fixedly installed at the end of spring 111. By setting spring 111 and protective ring 112, it is beneficial to reduce the pressure by the contraction and rebound of spring 111 when protective tube 1 and protective tube 2 are subjected to pressure, thereby improving the protection effect on the cable.

[0030] like Figure 2 and Figure 4As shown, there are two sets of spring 103, connecting block 104, locking block 105, fixing pin 106 and connecting rope 108. The two sets of spring 103, connecting block 104, locking block 105, fixing pin 106 and connecting rope 108 are symmetrically distributed on both sides of the rotating shaft 107. By limiting the number and position of spring 103, connecting block 104, locking block 105, fixing pin 106 and connecting rope 108, it is beneficial to improve the stability and firmness of the connection and fixation of protective tube 1 and protective tube 2, and ensure the normal protective effect of the device.

[0031] The technical solution provided by this utility model, during operation, involves placing the cable on the top of the inner wall of the second protective tube 2, and then connecting the first protective tube 1 to the second protective tube 2. When the fixing pin 106 at the top of the second protective tube 2 is inserted into the square groove 101, the locking block 105 is pressed by the fixing pin 106, causing the locking block 105 and the connecting block 104 to move deeper into the circular groove 102. When the fixing pin 106 is fully inserted into the square groove 101, the locking block 105 loses its pressing force, and the spring 103... Push the connecting block 104 and the locking block 105 towards the position of the fixing pin 106 until they are locked in place. When the cable needs maintenance, simply rotate the shaft 107. The rotation of the shaft 107 will cause the connecting rope 108 to wrap around the outer wall of the shaft 107. Then, the connecting rope 108 will pull the connecting block 104 and the locking block 105 into the depth of the circular groove 102, so that the locking block 105 can be separated from the fixing pin 106, and the protective tube 1 and the protective tube 2 can be separated.

[0032] By setting spring 111 and protective ring 112, the contraction and rebound of spring 111 can weaken the pressure when protective tube 1 and protective tube 2 are subjected to pressure, thereby improving the protection effect on the cable.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
