Description

Technical Field

[0001] This utility model relates to the field of wire fixing technology, specifically a wire restraint device. Background Technology

[0002] A wire restraint device is a device used to fix wires to a set position. It is widely used in the field of wire fixing technology. In the use of existing wire restraint devices, the covering half-ring is fixed to the laying position by the limiting pin. The covering half-ring clamps and fixes the wire to the laying position. However, since the slack of the wire on the device needs to be adjusted manually during the laying process, the slack of the wire between devices is difficult to control. This increases the probability of deformation and damage of the wire during thermal expansion and contraction, thus affecting the practicality of the device.

[0003] Based on this, the present invention designs a wire restrainer to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, this utility model provides a wire restraint device, which solves the problems mentioned in the background art.

[0012] Preferably, each set of limiting brackets has two sets of reinforcing ribs on its outer surface, and each set of reinforcing ribs has a weight reduction hole at its top.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a wire restraint device, which has the following beneficial effects:

[0015] 1. This wire restraint device moves the limiting component along the guide rail, causing the tension spring to elastically deform under the action of the limiting nut. After the tension spring is fully compressed, the wire is placed on the top of the limiting bracket in a slightly loose state. Then, the clamping arc plate fixes the wire with the cooperation of the limiting bracket. Next, the tension spring restores its deformation, causing the limiting component to move along the guide rail. The limiting component straightens the slightly loose wire, improving the convenience of controlling the wire slack between devices and reducing the probability of wire deformation and damage during thermal expansion and contraction.

[0016] 2. This conductor restraint device, through the adjusting screw and adjusting nut, allows the installer to determine the tension force according to the type of conductor. After the tension force is determined, rotating the adjusting nut causes it to move along the adjusting screw under the engagement of the thread. The adjusting nut changes the pre-compression stress of the tension spring, effectively improving the device's adaptability to different types of conductors, greatly enhancing the device's versatility, and thus increasing its practicality.

[0017] 3. This wire restraint device, through the tension spring, causes the limiting bracket to form a tight hoop structure with the cooperation of the clamping arc plate. Under the cooperation of the tight hoop structure, the wire drives the limiting component to move along the guide circular rail. During this process, the tortuous wire between the two sets of limiting components is tightened. At the same time, the limiting component causes the tension spring to elastically deform, and the impact stress is converted into the deformation stress of the tension spring. The deformed tension spring reduces the deformation stress by driving the limiting component to reciprocate along the guide circular rail, which effectively improves the impact resistance of the device and thus enhances the practicality of the device.

[0022] 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.

[0023] Please see Figure 1-3This utility model provides a technical solution: a wire restraint device, including a support bracket 1. The top of the support bracket 1 has two sets of support holes, and a guide rail 2 is inserted into the inner wall of each set of support holes. Limiting components 3 are provided on both the upper and lower sides of the support bracket 1. By moving the limiting components 3 along the guide rails 2, the tension spring 10 elastically deforms under the cooperation of the limiting nut 6. After the tension spring 10 is fully compressed, the wire is placed in a slightly loose state on the top of the limiting bracket 4. Then, the clamping arc plate 7 fixes the wire under the cooperation of the limiting bracket 4. Then, the tension spring 10... The limiting component 3 moves along the guide rail 2 due to the deformation recovery, straightening the slightly loose wire. This improves the convenience of controlling the wire slack between devices and reduces the probability of wire deformation damage during thermal expansion and contraction. Each limiting component 3 includes a limiting bracket 4. The top of each limiting bracket 4 has two sets of guide holes for sliding insertion into the guide rail 2. The front of each limiting bracket 4 is fixedly mounted with a clamping arc plate 7 by limiting bolts 5 and limiting nuts 6. Each guide rail 2 has a pressure adjusting screw 8 at both the top and bottom. The outer surface of each of the devices is screwed with adjusting nuts 9. Through the adjusting screw 8 and adjusting nuts 9, the installer determines the tension force according to the type of conductor. After the tension force is determined, rotating the adjusting nuts 9 causes them to move along the adjusting screw 8 with the help of the threads. This changes the pre-compression stress of the tension springs 10, effectively improving the adaptability of the device to different types of conductors and greatly enhancing its versatility and practicality. Each set of adjusting nuts 9 has a tension spring 10 at its inner end, and the inner end of each set of tension springs 10 is connected to a corresponding limiting bracket 4. The surface is bonded together, and through the tension spring 10, the limiting bracket 4 forms a tight hoop structure with the cooperation of the clamping arc plate 7. The wire drives the limiting component 3 to move along the guide rail 2 under the cooperation of the tight hoop structure. During this process, the tortuous wire between the two sets of limiting components 3 is tightened. At the same time, the limiting component 3 drives the tension spring 10 to elastically deform. The impact stress is converted into the deformation stress of the tension spring 10. The deformed tension spring 10 reduces the deformation stress by driving the limiting component 3 to move back and forth along the guide rail 2, which effectively improves the impact resistance of the device and thus enhances the practicality of the device.

[0024] In this utility model, in order to reduce the probability of damage to the wires during the operation of the device, buffer pads 11 are provided on the inner side of each set of limiting brackets 4 and clamping arc plates 7 to reduce the hardness of the contact surface between the device and the wires. Multiple anti-slip grooves are provided on the inner side of each set of buffer pads 11, thereby reducing the probability of damage to the wires during the operation of the device.

[0025] In this utility model, in order to improve the stability of the device during operation, anti-loosening nuts 12 for applying preload to the pressure adjusting nut 9 are screwed onto the outer surface of each set of pressure adjusting screws 8. The inner end of each set of anti-loosening nuts 12 is pressed against the outer end of the corresponding pressure adjusting nut 9, thereby improving the stability of the device during operation.

[0026] In this utility model, in order to extend the effective service life of the guide rail 2, a self-lubricating guide sleeve 13 is installed on the inner wall of each group of guide holes to reduce the friction between them and the guide rail 2. The inner wall of each group of self-lubricating guide sleeve 13 is slidably fitted with the outer surface of the corresponding guide rail 2, thereby extending the effective service life of the guide rail 2.

[0027] In this utility model, in order to improve the convenience of the device installation process, compensation slots 14 are provided at the four corners of the back of the support bracket 1 to compensate for the preset hole position error. The length of each set of compensation slots 14 is 2.5 times its width, thereby improving the convenience of the device installation process.

[0028] In this utility model, in order to reduce the probability of deformation failure of the limiting bracket 4, two sets of reinforcing ribs 15 are provided on the outer surface of each set of limiting brackets 4 to improve its structural strength. Each set of reinforcing ribs 15 has a weight reduction hole at the top, thereby reducing the probability of deformation failure of the limiting bracket 4.

[0029] In use, the device is first fixed to the installation location using the support bracket 1. After installation, the tension is determined according to the type of wire. Once the tension is determined, the adjusting nut 9 is rotated. The adjusting nut 9 moves along the adjusting screw 8 with the threaded engagement, changing the pre-compression stress of the tension spring 10. This causes the limiting bracket 4 to move along the guide rail 2. With the cooperation of the limiting nut 6, the limiting bracket 4 causes the tension spring 10 to elastically deform. After the tension spring 10 is fully compressed, the wire is placed on top of the limiting bracket 4 in a slightly loose state. Then, the clamping arc plate 7 is fixed to the limiting bracket 4 using the limiting bolt 5 and the limiting nut 6. The clamping arc plate 7 fixes the wire with the cooperation of the limiting bracket 4. The tension spring 10, through its restoring deformation, drives the limiting bracket 4 to move along the guide rail 2. With the cooperation of the clamping arc plate 7, the limiting bracket 4 straightens the slightly loose wire. At this time, there is a partially bent wire between the two sets of limiting components 3. When the wire is subjected to external impact, the limiting bracket 4, with the cooperation of the clamping arc plate 7, forms a clamping structure. With the cooperation of the clamping structure, the wire drives the limiting component 3 to move along the guide rail 2. During this process, the bent wire between the two sets of limiting components 3 is tightened. At the same time, the limiting component 3 drives the tension spring 10 to elastically deform. The impact stress is converted into the deformation stress of the tension spring 10. The deformed tension spring 10 reduces the deformation stress by driving the limiting component 3 to reciprocate along the guide rail 2.

[0030] In summary, this wire restraint device, by moving the limiting component 3 along the guide rail 2, causes the tension spring 10 to elastically deform under the cooperation of the limiting nut 6. After the tension spring 10 is fully compressed, the wire is placed on the top of the limiting bracket 4 in a slightly loose state. Then, the clamping arc plate 7 fixes the wire in cooperation with the limiting bracket 4. Then, the tension spring 10 restores its deformation and moves the limiting component 3 along the guide rail 2. The limiting component 3 straightens the slightly loose wire, which improves the convenience of controlling the wire slack between devices and reduces the probability of wire deformation and damage during thermal expansion and contraction.

[0031] This wire restraint device, through the adjusting screw 8 and adjusting nut 9, allows the installer to determine the tension force according to the type of wire. After the tension force is determined, the adjusting nut 9 is rotated, and the adjusting nut 9 moves along the adjusting screw 8 under the engagement of the thread. The adjusting nut 9 drives the change of the pre-compression stress of the tension spring 10, which effectively improves the adaptability of the device to different types of wires, greatly enhances the versatility of the device, and thus enhances the practicality of the device.

[0032] This wire restraint device, through the tension spring 10, causes the limiting bracket 4 to form a tight hoop structure with the cooperation of the clamping arc plate 7. Under the cooperation of the tight hoop structure, the wire drives the limiting component 3 to move along the guide circular rail 2. During this process, the tortuous wire between the two sets of limiting components 3 is tightened. At the same time, the limiting component 3 drives the tension spring 10 to elastically deform. The impact stress is converted into the deformation stress of the tension spring 10. The deformed tension spring 10 reduces the deformation stress by driving the limiting component 3 to reciprocate along the guide circular rail 2, which effectively improves the impact resistance of the device and thus enhances the practicality of the device.
