DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] Embodiment one: please refer to Figure 1 - Figure 6The utility model provides following technical scheme: A power distribution network equipment connecting hardware intelligent detector, including mounting seat 1, mounting seat 1 top middle fixedly connected with handle 2, and handle 2 middle installation has controller, mounting seat 1 inside middle fixedly connected with sleeve 5, and sleeve 5 is hollow structure, sleeve 5 middle is equipped with air supply chamber 6, and air supply chamber 6 both sides are equipped with the symmetric distribution of installation sliding hole 7, and installation sliding hole 7 inside fixedly connected with bellows 8, and bellows 8 is installed in air supply chamber 6 both sides, and bellows 8 far from air supply chamber 6 one end fixedly connected with drive block 9, mounting seat 1 inside both sides are fixedly connected with the symmetric distribution of installation sliding rod 3, and installation sliding rod 3 outside installation has the clamping structure that carries out the fixed of cable, and installation sliding rod 3 both ends are equipped with the buffer structure that carries out the buffer of clamping structure, mounting seat 1 inside fixedly connected with air pump 4, and air pump 4 output and air supply chamber 6 inside are connected with each other, and air pump 4 is controlled by the controller of handle 2 top, air supply chamber 6 and bellows 8 connecting place and bellows 8 and drive block 9 connecting place form sealed structure, and drive block 9 slidingly connects in installation sliding hole 7 inside, and drive block 9 far from bellows 8 one end and clamping structure mutual contact.

[0027] The operator first passes two cables to be tested through the fixed region of the clamping structure, ensuring that the hardware is correctly connected and located between the two clamping structures. By adjusting the clamping structure, the cables are kept in a stable state, avoiding loosening or deviation, providing accurate initial conditions for subsequent testing.

[0028] When the cable fixing is completed, the operator starts the air pump 4 through the controller on the handle 2, and the air pump 4 begins to fill the air into the air supply chamber 6, causing the internal pressure of the air supply chamber 6 to rise. Since the air supply chamber 6 is connected to the bellows 8, the bellows 8 is also affected by the internal gas pressure and expands, causing the bellows 8 to elongate along its axial direction. The extension of the bellows 8 further pushes the drive block 9 to slide along the installation sliding hole 7, ultimately driving the drive block 9 into contact with the clamping structure.

[0029] When the drive block 9 comes into contact with the clamping structure, as the internal pressure of the air supply chamber 6 continues to rise, the drive block 9 continues to push the clamping structure outward. Under the action of the drive block 9, the clamping structure moves in opposite directions, i.e., expands away from each other. This applies a pulling force to the clamped cables, indirectly testing the pulling force of the connected hardware.

[0030] The air pump 4 continuously inflates, increasing the pressure inside the bellows 8 and the air supply chamber 6. This pressure data is displayed in real time on the handle 2, allowing the operator to observe the current pulling force at any time. When the air pressure reaches the set value, but the hardware has not broken or fallen off, it indicates that the hardware connection is firm and meets the use requirements.

[0031] When the test is over, the operator controls the air pump 4 to release air through handle 2. The air pressure inside the air supply chamber 6 decreases, the bellows 8 contracts, and the drive block 9 returns to its initial position. At the same time, the clamping structure returns to its original position, and the cable is released, making it easy to remove the hardware and cable. If the hardware is subjected to a tensile force exceeding the limit value during the test and breaks or separates, the clamping structure will quickly slide to both sides. To prevent the equipment from being damaged by impact due to the sudden loss of tensile force, the buffer structure will play a shock absorption role and prevent the clamping structure from being subjected to excessive impact.

[0032] Example 2: Based on Example 1, a clamping structure is also disclosed, the specific structure of which is as follows: Preferably, the clamping structure includes a slider 10 slidably connected to the outside of the mounting slider 3, and a lower fixing plate 11 is fixedly connected to the top of the slider 10. Both ends of the lower fixing plate 11 are fixedly connected to the top of the lower fixing plate 11, and a fixing beam 13 is fixedly connected to the top of the connecting rod 12. An upper fixing plate 14 is slidably connected between the two connecting rods 12, and a self-tightening screw 15 is threadedly connected to the middle of the fixing beam 13. The lower end of the self-tightening screw 15 and the top of the upper fixing plate 14 are in contact with each other. A first spring 16 is fixedly connected between the bottom of the upper fixing plate 14 and the lower fixing plate 11, and the first spring 16 is installed on the outside of the connecting rod 12.

[0033] In the initial state, the self-tightening screw 15 is in a loose state, causing its lower end to separate from the upper fixing plate 14. Under the elastic force of the first spring 16, the upper fixing plate 14 slides upward between the connecting rods 12, increasing the distance between it and the lower fixing plate 11 so that the cable can smoothly enter the clamping area.

[0034] After the cable passes through the gap between the upper fixing plate 14 and the lower fixing plate 11, adjust the position of the cable to place it at a suitable center point to ensure uniform force. Rotate the self-tightening screw 15 so that its lower end gradually contacts the upper fixing plate 14. Continue to rotate the self-tightening screw 15 to force the upper fixing plate 14 to move downward, thereby gradually clamping the cable and achieving a stable fixation. Since the distance between the upper fixing plate 14 and the lower fixing plate 11 is adjustable, it can be used for cables of different diameters, thus improving the applicability of the equipment.

[0035] Example 3: Based on Examples 1 and 2, a buffer structure is also disclosed, the specific structure of which is as follows: The buffer structure includes a buffer block 17 slidably connected between two mounting slide rods 3, and the two ends of the buffer block 17 are aligned with the two ends of the slider 10; a second spring 18 is fixedly connected between the two ends of the buffer block 17 and the two ends inside the mounting base 1, and the second spring 18 is installed on the outside of the mounting slide rod 3; an airbag 19 is fixedly connected between the buffer block 17 and the two ends inside the mounting base 1, and the opening of the airbag 19 extends to the outside of the end of the mounting base 1.

[0036] When the two clamping structures suddenly lose the tension between the cable and the fitting, at this time the slider 10 will slide on the installation slide rod 3 until the slider 10 and the buffer block 17 are in contact with each other, when the buffer block 17 and the slider 10 are in contact with each other, the slider 10 will drive the second spring 18 and the air bag 19 to compress at the same time, and the gas in the air bag 19 will be discharged outward through the opening, since the opening is limited in size, the speed of the air bag 19 discharging gas is limited, thereby controlling the speed of the air bag 19 and the second spring 18 shrinking, preventing the impact force of the slider 10 on the buffer block 17 from being too large to cause the buffer block 17 to lose the buffering effect, and after the buffering, the second spring 18 drives the buffer block 17 to reset, which can drive the air bag 19 to reset.

[0037] In the normal test process, after the clamping structure applies tension, if the fitting is not damaged, it will not affect the buffering system of the equipment, but if the fitting suddenly breaks or falls off, the clamping structure will quickly slide outward due to the loss of the reverse tension, and may hit the mounting seat 1.

[0038] When the clamping structure loses the resistance of the cable, the slider 10 will quickly slide along the installation slide rod 3 and finally contact the buffer block 17, after the buffer block 17 is hit by the slider 10, the second spring 18 will be deformed, and at the same time the air bag 19 will be compressed, the air in the air bag 19 will be slowly discharged through the opening, since the opening is small, the exhaust speed is limited, therefore the air bag 19 will not be compressed completely at once, but will slowly release the internal gas, thereby effectively reducing the impact force.

[0039] After being compressed, the second spring 18 will also store part of the potential energy and then gradually release it, so that the buffer block 17 returns to the original position, this double buffering mechanism ensures that the slider 10 will not be damaged due to excessive impact force, and also protects the entire clamping structure, after buffering, the rebounding action of the second spring 18 makes the buffer block 17 return to the original position, since the buffer block 17 is connected with the air bag 19, the resetting of the buffer block 17 will also drive the air bag 19 to return to the original state, ready for the next test.

[0040] In the description of the utility model, it should be explained that, unless there is clear provision and limitation, the terms "connected" and "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be indirectly connected through an intermediate medium. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0041] Although the utility model has been explained in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
