[0002] During the production and use of cables, various performance tests are frequently required, such as tensile strength tests, conductivity tests, and insulation tests. During these tests, limiting structures are needed to securely fix the cables to the testing equipment to ensure the accuracy and reliability of the tests.

[0003] In terms of structure, the limiting structure of existing testing equipment mostly adopts a clamp-type working structure, which often has the following problems: If the cable is not securely fixed, it is prone to displacement during testing, which will affect the test results. The operation is inconvenient, and the fixing and disassembly process is cumbersome, which reduces testing efficiency. It has poor adaptability to different cable specifications and cannot meet diverse testing needs.

[0004] To address the aforementioned issues, an auxiliary fastening fixture for testing cables is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary fastening fixture for testing cables, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary fastening fixture for testing cables, comprising a mounting support and a clamping mechanism for clamping and limiting the testing cables, wherein a limiting sleeve is provided on the upper part of the mounting support, and the clamping mechanism is installed on the inner side of the limiting sleeve. The clamping mechanism includes a conical clamping block and a limiting ring seat. Multiple conical clamping blocks are provided. After several conical clamping blocks are assembled, they are fitted into the conical groove cavity provided in the middle of the limiting ring seat. The cable clamping groove is provided in the middle of the conical clamping block. The limiting ring seat is ring-shaped and is threadedly installed on the rear opening side of the limiting cylinder seat. After installation, the front part of the limiting ring seat pushes against and supports the rear part of the conical clamping block.

The conical clamping block is connected and installed using a limiting cylinder seat installed on the upper part of the mounting support. The split conical clamping block is fitted into the conical groove cavity in the middle of the limiting cylinder seat. Through the fitting and pushing of the conical groove cavity, the cable can be clamped and limited from the periphery. The structure is simple and the operation is reliable.

Example

[0021] Please see Figure 1-6 This utility model provides a technical solution: an auxiliary fastening fixture for testing cables, including a mounting support 1 for clamping and limiting the test cables and a clamping mechanism. The mounting support 1 is used for mounting support of the clamping mechanism, as shown in the attached figure. Figure 2 As shown, in order to facilitate positioning and installation with the traction platform of the test equipment, mounting positioning blocks 6 are fixed on both sides of the lower part of the mounting support 1. The mounting positioning blocks 6 protrude from the bottom of the mounting support 1 and are installed and positioned by fitting with the upper groove of the traction platform. The mounting positioning blocks 6 can also improve the tensile strength of the mounting support 1. In order to facilitate the installation limit of the mounting support 1, bolt mounting holes 5 are opened through the four corners of the upper part of the mounting support 1. Fastening bolts are installed inside the bolt mounting holes 5. The mounting support 1 is fixedly installed with the platform of the test equipment by fastening bolts.

[0022] To facilitate the installation and operation of the clamping mechanism, a limiting sleeve 2 is provided on the upper part of the mounting support 1, as shown in the attached figure. Figure 3 As shown, the limiting sleeve seat 2 is fixedly installed on the upper front side of the mounting support 1, and the clamping mechanism is installed on the inner side of the limiting sleeve seat 2. The clamping mechanism includes a conical clamping block 3 and a limiting ring seat 4, as detailed in the attached diagram. Figure 5 As shown, to facilitate the connection and installation of the conical clamping block 3, a conical groove 7 is provided in the middle of the limiting cylinder seat 2. The conical groove 7 is opened through the middle of the limiting cylinder seat 2. The conical clamping block 3 is used for the limiting clamping and installation of the test cable, as shown in the attached figure. Figure 3As shown, three conical clamping blocks 3 are provided. After the three conical clamping blocks 3 are assembled, they are fitted into the conical groove 7 in the middle of the limiting cylinder seat 2. Specifically, the three conical clamping blocks 3 are arranged in a circumferential distribution and assembled. After assembly, the conical clamping blocks 3 slide into the groove side of the conical groove 7. A conical block clamping and limiting working structure is adopted. The conical clamping blocks 3 are connected and installed by the limiting cylinder seat 2 installed on the upper part of the mounting support 1. The separate conical clamping blocks 3 are fitted into the conical groove 7 in the middle of the limiting cylinder seat 2. The engagement guide of cavity 7 can clamp and limit the cable from the periphery. The structure is simple and the operation is reliable. The conical clamping block 3 provides clamping force by pulling the cable. With the support of the conical groove cavity 7, the cable can be stably clamped and limited. The greater the pulling force, the more stable the clamping. It can effectively improve the clamping and limiting stability of the test cable. The conical clamping block 3 is positioned by the engagement support of the conical groove cavity 7 in the middle of the limiting cylinder seat 2. There is no need for complicated fastening and locking operations. The cable clamping and installation can be completed conveniently and quickly. Compared with the traditional clamp-type installation structure, it has better installation and operation convenience.

[0023] To facilitate the clamping and installation of test cables, see attached... Figure 6 As shown, a cable clamping groove is provided in the middle of the conical clamping block 3. The cable clamping groove is opened on the inner circumference of the conical clamping block 3. By combining the separately set conical clamping blocks 3, the stable clamping support of cables of different specifications can be achieved, so that the tooling can meet the clamping and installation requirements of cables of different specifications. In order to improve the clamping stability of the test cable, anti-slip grooves 8 are evenly and equidistantly opened on the inner groove surface of the cable clamping groove. Limiting toothed nails 9 are evenly and equidistantly fixed on the inner groove surface of the cable clamping groove. After clamping, the clamping support of the anti-slip grooves 8 and the piercing support of the limiting toothed nails 9 can effectively improve the clamping support stability of the test cable.

[0024] The limiting ring seat 4 is a ring-shaped seat used for pressing and locking the conical clamping block 3 after installation, as shown in the attached figure. Figure 3As shown, to facilitate the connection and installation of the limiting ring seat 4, a mounting screw 10 is provided at the rear of the conical groove cavity 7. The limiting ring seat 4 is installed with the rear open side thread of the limiting cylinder seat 2 through the mounting screw 10. After installation, the front of the limiting ring seat 4 is pushed and supported by the rear of the conical clamping block 3. The rear push of the limiting ring seat 4 can achieve pre-tightening of the cable clamping after installation, preventing the cable from coming out due to excessive clamping. Furthermore, the limiting support of the limiting ring seat 4 can prevent... During testing, the conical clamping block 3 is ejected due to the rebound of the broken cable. This not only improves the convenience of cable clamping operations but also effectively enhances the stability of cable clamping and installation and testing safety. To facilitate the tightening operation of the limiting ring seat 4, four circular slots 11 are provided at the rear of the limiting ring seat 4. These four circular slots 11 are circumferentially located at the rear of the limiting ring seat 4. By cooperating with a special wrench, the limiting sleeve seat 2 can be quickly tightened.

[0025] Working principle or structural principle: During operation, the fixture is installed on the upper part of the traction platform of the testing equipment using the mounting bracket 1. During testing, a conical clamping block 3 compatible with the test cable is selected. Then, the cable end is inserted into the groove in the middle of the limiting sleeve 2. Next, three sets of conical clamping blocks 3 are sequentially connected and installed on the outside of the cable. After completion, the assembled conical clamping blocks 3 are moved and fitted into the inner side of the conical groove 7 in the middle of the limiting sleeve 2. The conical clamping blocks 3 are initially tightened and limited by pulling the cable. Then, the limiting ring seat 4 is screwed into the inner side of the mounting screw hole 10 at the rear of the limiting sleeve 2. Finally, a special wrench with a protruding fastening part is used in conjunction with the circular slot 11 at the rear of the limiting ring seat 4. After installation, the limiting ring seat 4 is tightened and locked. The limiting ring seat 4 pushes against the rear of the conical clamping block 3 to achieve pre-tight clamping of the clamped cable. Then, the pulling platform drives the limiting cylinder seat 2 to move and pull the cable to tension. During the pulling process, the conical clamping block 3 relies on the pulling of the clamping cable to provide clamping force. With the guide support of the conical groove cavity 7, the cable can be stably clamped and limited. The greater the pulling force, the more stable the clamping, which can achieve the stable clamping and limiting of the cable. When the test cable breaks due to force, the conical clamping block 3 rebounds and moves backward due to the rebound force of the breakage. During the process, the limiting ring seat 4 limits and supports, which can prevent the conical clamping block 3 from flying out due to the rebound of the broken cable during the test, which greatly improves the safety of the cable testing work.

[0026] In summary, this fastening fixture adopts a conical block clamping and limiting working structure. The conical clamping block 3 is connected and installed using a limiting sleeve 2 mounted on the upper part of the mounting support 1. The separate conical clamping block 3 is fitted into the conical groove 7 in the middle of the limiting sleeve 2. The fitting and guiding action of the conical groove 7 allows for clamping and limiting of the cable from the periphery. The structure is simple and the operation is reliable. The conical clamping block 3 relies on the tension of the clamping cable to provide clamping force. Combined with the guiding support of the conical groove 7, it achieves stable clamping and limiting of the cable. The greater the tension, the more stable the clamping, effectively improving the clamping and limiting stability of the test cable. Furthermore, through the combined clamping of the separately set conical clamping blocks 3, it can achieve stable clamping and support of cables of different specifications, allowing the fixture to meet the needs of different specifications. For cable clamping and installation, the conical clamping block 3 is positioned and supported by the conical groove 7 in the middle of the limiting cylinder seat 2. This eliminates the need for complex tightening and locking operations, allowing for convenient and quick cable clamping and installation. Compared to traditional clamp-type installation structures, this offers better installation convenience. A limiting ring seat 4 is installed at the rear of the limiting cylinder seat 2 via the mounting screw 10. The rear of the limiting ring seat 4 pushes against the cable, pre-tightening the clamped cable after installation to prevent it from coming loose. Furthermore, the limiting ring seat 4's limiting support prevents the conical clamping block 3 from flying out due to cable breakage and rebound during testing. This improves both the convenience of cable clamping operations and the stability and safety of cable clamping and installation during testing.
