[0031] The adjusting mechanism 3 includes a limiting tube 31, an airbag 32, a silicone hose 33 and an inflation tube 34. The silicone hose 33 is fixedly connected to the right side of the connecting tube 2. The airbag 32 is fixedly connected to the surface of the silicone hose 33.

[0032] In this embodiment: by setting the test fixture body 1 as the core infrastructure of the entire device, a stable operating platform is provided for the cable terminal pressure test. By setting the connecting pipe 2 to connect the test fixture body 1 and the adjustment mechanism 3, the cable terminal can enter the inner side of the test fixture body 1. By setting the limiting pipe 31, the airbag 32 is provided with external support and protection to prevent the airbag 32 from being excessively deformed or damaged when affected by external pressure or other factors. At the same time, it also fixes and limits the internal silicone hose 33 and the inflation tube 34 and other components, ensuring that the entire adjustment mechanism 3 The structural stability is ensured. The airbag 32 is one of the key components of the adjustment mechanism 3. Its volume can be flexibly changed by inflation and deflation to adapt to cables of different diameters. The silicone hose 33 has good flexibility and sealing performance. It can be shrunk along with the airbag 32 when the airbag 32 changes its volume, thereby adapting to and fitting cables of different diameters. The inflation tube 34 is a channel connecting the airbag 32 and the inflation mechanism 4, which is responsible for delivering the gas generated by the inflation mechanism 4 to the airbag 32, ensuring that the gas can be accurately and quickly filled into the airbag 32, thereby achieving tight fixation of the cable.

[0033] Specifically, such as Figure 3 、 Figure 4 As shown, the inflation mechanism 4 includes an air delivery pipe 41 , a solenoid valve 42 , an air intake pipe 43 and a mini air pump 44 , and the air delivery pipe 41 is fixedly connected to the top of the inflation pipe 34 .

[0034] Specifically, such as Figure 3 、 Figure 4 As shown, the solenoid valve 42 is fixedly connected to the left side of the air delivery pipe 41 , and the air intake pipe 43 is fixedly connected to the left side of the solenoid valve 42 .

[0035] Specifically, such as Figure 3 、 Figure 4 As shown, the mini air pump 44 is fixedly connected to the left side of the top of the limiting tube 31, the left side of the air intake pipe 43 is fixedly connected to the right side of the mini air pump 44, and the air supply pipe 41, the solenoid valve 42, the air intake pipe 43, the mini air pump 44 and the air pipe 34 are connected.

[0036] In this embodiment: by setting up an air supply pipe 41, gas is transmitted from the inflation mechanism 4 to the inflation pipe 34, providing a channel for the inflation of the airbag 32, and by setting up an electromagnetic valve 42, the on and off of the gas can be precisely controlled to realize automatic control of the inflation and deflation of the airbag 32. During the cable terminal pressure test, the pressure of the airbag 32 can be adjusted at any time as needed to improve the fixation of cables of different sizes.

[0037] Specifically, such as Figure 4 As shown, a sealing ring 5 is bolted to one side of the gas pipe 41 close to the solenoid valve 42 , and a side of the sealing ring 5 away from the gas pipe 41 is fixedly connected to the right side of the solenoid valve 42 .

[0038] Specifically, such as Figure 4 As shown, the air-sealing cushion 6 is bolted to one side of the air inlet pipe 43 close to the mini air pump 44 , and the air-sealing cushion 6 is bolted to the right side of the mini air pump 44 away from the air inlet pipe 43 .

[0039] In this embodiment: by providing a sealing ring 5, it is possible to prevent gas from leaking from the connection between the gas pipe 41 and the solenoid valve 42 during transmission, ensuring that the inflation mechanism 4 can stably provide gas to the airbag 32, thereby ensuring the normal operation of the entire cable terminal pressure test fixture, and improving the accuracy and reliability of the test; by providing an air-sealing cushion 6, it is possible to effectively prevent external air or impurities from entering the air inlet pipe 43, ensuring the purity of the gas entering the inflation mechanism 4, and avoiding damage to the internal structure of the test fixture.

[0040] Specifically, such as Figure 5 As shown, a support bracket 7 is fixedly connected to the bottom of the test fixture body 1, and the surface of the support bracket 7 is coated with anti-static paint.

[0041] Specifically, such as Figure 5 As shown, a universal wheel 8 is fixedly connected to the bottom of the support bracket 7, and the surface of the universal wheel 8 is engraved with anti-slip patterns.

[0042] In this embodiment: by providing a support frame 7, a stable support is provided for the test tool body 1, which can ensure that the test tool remains stable during use and prevent the test results from being affected by shaking or tilting. By providing an anti-static coating, the generation of static electricity can be prevented, and static electricity can be avoided from interfering with the cable terminal withstand voltage test, thereby ensuring the accuracy of the test data. By providing a universal wheel 8, the entire cable terminal withstand voltage test tool has good mobility.

[0043] Specifically, such as Figure 5 As shown, a handle 9 is fixedly connected to the left side of the support bracket 7, and the surface of the handle 9 is coated with anti-corrosion paint.

[0044] Specifically, such as Figure 5 As shown, the surface of the handle 9 is covered with a protective cover 10 , and the surface of the protective cover 10 is engraved with anti-slip lines.

[0045] In this embodiment: by providing a handle 9, a convenient gripping position is provided for the operator, which is convenient for pushing and controlling the movement of the test tooling; by providing an anti-corrosion coating, the handle 9 can be prevented from being corroded during long-term use, thereby extending its service life; by providing a protective cover 10, the friction of the handle 9 is further increased, preventing the operator's hands from slipping when holding the handle 9; by providing anti-slip patterns, the anti-slip effect is enhanced, and the safety and stability of the operation are improved; even when the hands are sweaty or wet, the anti-slip cover can ensure that the operator can firmly hold the handle 9 and smoothly move the test tooling.

[0046] Working principle: First, the user places the test fixture body 1 in a suitable working position. Then, when it is necessary to carry out a pressure test on cables of different diameters, the staff holds the handle 9 and pushes the handle 9 to move the universal wheel 8 at the bottom of the support frame 7, thereby moving the test fixture body 1 to the required position. After that, if the cable needs to be fixed, the user turns on the power and starts the mini air pump 44, and the gas flows into the solenoid valve 42 through the air inlet pipe 43. The solenoid valve 42 can accurately control the on and off of the gas. When the solenoid valve 42 is opened, the gas is transmitted to the inflation pipe 34 through the gas pipe 41, and the inflation pipe 34 then transmits the gas to the airbag 32. The airbag 32 can change its own The silicone hose 33 has a small size and good flexibility and sealing performance. It can closely follow the airbag 32 when the volume of the airbag 32 changes, and adapt to cables of different diameters. The connecting pipe 2 connects the test fixture body 1 and the adjustment mechanism 3, so that the cable terminal can smoothly enter the inner side of the test fixture body 1. Finally, when the test fixture needs to be transferred to a different location, the user energizes the solenoid valve 42 and discharges the gas in the airbag 32. When the airbag 32 shrinks, it will drive the silicone hose 33 to expand. When the silicone hose 33 expands, it will loosen the cable. At this time, the user pushes the test fixture body 1 to move it to the next work location.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
