Description

Technical Field

[0001] This utility model relates to the field of power engineering, and in particular to a cable anti-loosening fastening and adjustment clamp for power distribution cabinets. Background Technology

[0002] Distribution cabinets are core equipment for power transmission and distribution. The reliability of their internal cable connections directly affects operational safety. Loose cables can easily lead to risks such as poor contact, overheating, or even fire. Moreover, distribution cabinets are often in complex environments with vibration and temperature changes. They need to be compatible with multiple cable specifications and adapt to compact spaces. Traditional fixing methods such as nylon cable ties and metal wire clips have problems such as inconvenient adjustment, easy damage to cables, and poor adaptability. With the development of smart grids, the application scenarios of distribution cabinets are increasing, which puts forward higher requirements for the reliability and convenience of cable fixing. As a result, cable anti-loosening fastening and adjustment clamps for distribution cabinets have emerged.

[0003] The cable anti-loosening fastening adjustment clamp of the power distribution cabinet achieves reliable fixation through the cooperation of multiple structures. The elastic clamping structure uses stainless steel spring sheets with an arc design that deforms with the diameter of the cable. The anti-slip texture on the inner side enhances friction. Combined with rubber and silicone pads, it avoids damage to the cable through elastic buffering, while compensating for gaps caused by vibration and thermal expansion and contraction, and providing continuous clamping force. The anti-loosening limit structure enhances reliability through axial constraint. The barbed protrusion clamps the cable at an angle of ≤45°. The greater the pulling force, the stronger the clamping force. The U-shaped limit baffle rotates to lock the cable inlet and outlet. The inner rubber pad provides flexible constraint. The elastic locking ring is installed at the outlet and uses the radial contraction force of the metal spring sheet or elastic rubber to prevent the cable from coming out.

[0004] Current cable anti-loosening fastening and adjustment clamps for distribution cabinets play a positive role in improving the reliability of cable fixing and the level of operation and maintenance in the industry. However, the high temperature environment generated by the long-term operation of electrical components inside the cabinet poses a challenge to the performance of the clamps. Elastic materials such as spring sheets will experience a decrease or failure in clamping force due to thermal expansion and contraction at high temperatures. Metals will soften and rubber pads will age and harden. Therefore, a cable anti-loosening fastening and adjustment clamp for distribution cabinets is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cable anti-loosening fastening adjustment clamp for power distribution cabinets, which aims to improve the problem of clamping force attenuation caused by thermal expansion and contraction of elastic materials in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cable anti-loosening fastening and adjusting clamp for a power distribution cabinet includes a housing. Two base blocks are fixedly connected to the outer wall of the housing. A shell is provided on one side of the housing. Two support blocks are fixedly connected to the outer wall of the shell. An adjusting column is threaded inside the housing. A clamping block is rotatably connected to one side of the adjusting column. An anti-slip groove is provided on the other side of the clamping block. An anti-vibration component is fixedly connected to the outer wall of the shell.

[0008] As a further description of the above technical solution:

[0009] The shock-absorbing component includes a connecting block, one side of which is fixedly connected to the outer wall of the housing, and the other side of which is fixedly connected to a connecting plate. Each of the four corners of one side of the connecting plate is fixedly connected to a telescopic column, and the other side of the four telescopic columns is fixedly connected to a base plate. The outer walls of the four base plates are all fitted with springs.

[0010] As a further description of the above technical solution:

[0011] The base block is internally threaded with a screw, and the outer wall of the screw is threaded into the inside of the support block.

[0012] As a further description of the above technical solution:

[0013] The base plate is internally threaded with a fixing post, and the outer wall of the fixing post is threadedly connected to the inside of the connecting plate.

[0014] As a further description of the above technical solution:

[0015] A groove is provided on one side of the fixing column, and the groove is cross-shaped;

[0016] As a further description of the above technical solution:

[0017] The anti-slip groove has a circular arc shape in cross-section, and the screw has a T-shaped cross-section.

[0018] As a further description of the above technical solution:

[0019] One side of the base block is in contact with one side of the support block, and the cross-sectional shape of the adjusting column is T-shaped;

[0020] As a further description of the above technical solution:

[0021] One side of the spring is fixedly connected to one side of the connecting plate, and the other side of the spring is fixedly connected to one side of the base plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the base block and the bearing block are tightly fixed by screws to form a stable mechanical structure, which avoids displacement of the outer shell and ensures the stability of the clamp. By rotating the internal adjusting column, the movement of the clamping block is precisely controlled by the threaded transmission, and the distance between its anti-slip groove and the shell can be flexibly adjusted to adapt to cables of different thicknesses, thereby improving versatility and utilization. The clamp is made of high-temperature resistant materials and has an optimized structure. Even if the power distribution cabinet operates under high load for a long time and heats up, it can maintain stable performance and continuously provide reliable clamping force. The anti-slip groove of the clamping block increases friction and fit. Combined with the shell's ring-shaped clamping, it resists the risk of loosening of cables caused by vibration and pulling, and ensures the safe operation of the power system.

[0024] 2. In this utility model, by using a Phillips screwdriver to press against the groove of the fixing column and screwing, the base plate and the connecting plate can be quickly and tightly connected. Then, the other side of the base plate is fixed to the distribution cabinet. This installation method is simple to operate and effectively improves assembly efficiency. When the distribution cabinet is running, vibration is unavoidable. The cooperation between the telescopic column and the spring in the fixture forms a highly efficient shock absorption system. When the vibration is transmitted from the base plate to the connecting plate, the spring absorbs the vibration energy through elastic deformation and converts it into elastic potential energy, effectively offsetting most of the external vibration force, greatly reducing the impact of vibration on the main structure of the fixture, significantly extending the service life of the fixture, and ensuring its long-term stable operation.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a cable anti-loosening fastening and adjusting clamp for a power distribution cabinet, comprising a housing 1. The housing 1 serves as the main load-bearing structure of the clamp, providing a stable installation base for the internal components. Two base blocks 9 are fixedly connected to the outer wall of the housing 1. The base blocks 9 are used for connection with other components and are one of the key parts for achieving overall clamp fixation. A housing 2 is provided on one side of the housing 1. The housing 2 cooperates with the housing 1 to form a clamping space, providing an installation area for the cable. Two bearing blocks 10 are fixedly connected to the outer wall of the housing 2. The bearing blocks 10 correspond to the base blocks 9, and the two cooperate to achieve a reliable connection between the housing 1 and the housing 2. An adjusting column 12 is threadedly connected inside the housing 1. The adjusting column 12 can achieve precise position adjustment through threaded transmission. A clamping block 13 is rotatably connected to one side of the adjusting column 12. The clamping block 13 can move under the drive of the adjusting column 12, thereby changing the distance between it and the housing 2. The other side of the clamping block 13... The clamp is provided with anti-slip grooves 14, which increase the contact friction with the cable and effectively prevent the cable from sliding during clamping, ensuring stable clamping effect. The outer wall of the housing 2 is fixedly connected with a shock-absorbing component, which is used to reduce the impact of vibration generated by the power distribution cabinet during operation on the clamp. The shock-absorbing component includes a connecting block 3, which serves as a bridge between the shock-absorbing component and the housing 2, ensuring that vibration can be effectively transmitted to the subsequent structure. One side of the connecting block 3 is fixedly connected to the outer wall of the housing 2, and the other side of the connecting block 3 is fixedly connected to a connecting plate 4, making the entire clamp more stable. Each of the four corners of one side of the connecting plate 4 is fixedly connected with a telescopic column 5, and the other side of the four telescopic columns 5 is fixedly connected to a base plate 15. The base plate 15 is the connecting part between the entire clamp and the power distribution cabinet, used to fix the clamp on the power distribution cabinet. The outer walls of the four base plates 15 are fitted with springs 6, which are the core components of shock absorption and can absorb vibration energy through elastic deformation.

[0033] Reference Figures 2 to 4The base block 9 has internal threads for screws 11, which pass through the base block 9 and the support block 10, tightly fixing the outer shell 1 and the housing 2 together, ensuring the overall stability of the fixture structure. The outer threads of the screws 11 are connected to the inside of the support block 10, ensuring the reliability of the connection. The base plate 15 has internal threads for fixing posts 7, which are used to connect the base plate 15 to the connecting plate 4, and also facilitate the installation and fixing of the fixture to the distribution cabinet. The outer threads of the fixing posts 7 are connected to the inside of the connecting plate 4, achieving reliable assembly of the base plate 15 and the connecting plate 4. A groove 8 is provided on one side of the fixing post 7, and the groove 8 is cross-shaped, which facilitates the use of a Phillips screwdriver to tighten the fixing post 7, improving installation efficiency. The anti-slip groove 14 has a circular arc cross-section, which can better fit the outer surface of the cable, increase the contact area, and further improve the anti-slip effect. The screw 11 has a T-shaped cross-section, which can effectively prevent the screw 11 from slipping out during installation and ensure the stability of the connection. One side of the base block 9 and one side of the support block 10 are in contact to ensure the uniform transmission of force when the screw 11 is connected. The adjusting column 12 has a T-shaped cross-section, which is convenient for manual operation to rotate the adjusting column 12 to adjust the position of the clamping block 13. One side of the spring 6 is fixedly connected to one side of the connecting plate 4, and the other side is fixedly connected to one side of the base plate 15, so that the spring 6 can play the role of elastic deformation when vibrating.

[0034] Working principle: A Phillips screwdriver is used to press against the groove 8, causing the fixing post 7 to connect one side of the base plate 15 to the connecting plate 4, and the other side of the base plate 15 to the distribution cabinet. Due to the cooperation of the four telescopic posts 5 and four springs 6, the vibration generated by the distribution cabinet is transmitted through the base plate 15 to the connecting plate 4, first passing through the springs 6. The elastic potential energy generated when the external force compresses the springs 6 cancels out most of the external force, significantly extending the service life of the entire fixture. The base block 9 and the bearing block 10 are fixed together by screws 11, thus firmly fixing the outer shell 1 and the housing 2. Then, the position is rotated... The adjustable column 12 inside the outer casing 1 allows the distance between the anti-slip groove 14 and the casing 2 to be adjusted by rotating the adjustable column 12. This makes the entire clamp adaptable to clamping various specifications of cables, greatly improving the utilization rate of the entire clamp. Moreover, the increased temperature inside the distribution cabinet after long-term clamping will not affect the clamp's working ability, greatly improving the clamping stability of the entire clamp. Furthermore, due to the presence of the anti-slip groove 14 on the clamping block 13, the clamping effect is more stable when the clamping block 13 cooperates with the casing 2 to clamp cables, greatly improving the safety of the entire operation.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
