Detailed implementation manners

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1

[0032] Please refer to Figures 1 to 5 , the present invention is a charging cable testing device, including a test bench 1 and a detection table arranged above the front end face thereof. An adjustment groove 102 is provided on one side of the upper surface of the test bench 1, and a slot 103 is provided at the central position of the inner side wall of the test bench 1. A pulling assembly 2 is arranged inside the adjustment groove 102; the pulling assembly 2 includes an adjustment motor 201 and a threaded rod 201a installed on its output shaft through a coupling. The other end of the threaded rod 201a sequentially passes through the threaded holes on the front moving block 202 and the rear moving block 203 and is connected to the bearing on the rear end face inside the adjustment groove 102.

[0033] Specifically, a surface survey mechanism 105 is slidably arranged directly above the test bench 1. A clamping mechanism 104 is arranged at one edge of the upper surface of the test bench 1. A charging wire body 106 is inserted into the slot 103. Support plates 204 are fixedly connected to the upper surfaces of the front moving block 202 and the rear moving block 203. A limiting plate 205 is arranged with a gap above the outer wall of the support plate 204. A connecting rod 206 is fixedly connected to the central position of the inner wall of the limiting plate 205. The other end of the connecting rod 206 passes through the through hole on the outer wall of the support plate 204 and is connected to the outer wall of the U-shaped frame 208. A spring 207 is sleeved on the outer side of the outer wall of the connecting rod 206. The spring 207 is located between the inner wall of the support plate 204 and the outer wall of the U-shaped frame 208. A rotating motor 209 is installed at the bottom of the U-shaped frame 208. The output shaft of the rotating motor 209 is connected to the rotating shaft 209a through a coupling. The other end of the rotating shaft 209a passes through the bearing at the bottom of the U-shaped frame 208 and is connected to the bearing at the top end inside the U-shaped frame 208. A roller 2010 is sleeved on the outer side of the outer wall of the rotating shaft 209a.

[0034] Furthermore, the detection table 101, the clamping mechanism 104, the surface survey mechanism 105, the charging wire body 106, etc. are all prior arts, so no more elaboration will be made here. When the adjustment motor 201 operates, it can drive the threaded rod 201a to rotate. Among them, positive threads and reverse threads are respectively arranged on both sides of the outer wall of the threaded rod 201a, and the positive threads and reverse threads are respectively meshed with the internal threads in the threaded holes on the front moving block 202 and the rear moving block 203. Therefore, when the threaded rod 201a rotates, it can drive the front moving block 202 and the rear moving block 203 to move in opposite and reverse directions. The cross-section of the support plate 204 is L-shaped. The limiting plate 205 and the U-shaped frame 208 are connected through the connecting rod 206, playing a role of connection and transmission. Under the elastic performance of the spring 207, the force exerted by the roller 2010 on the outer wall of the charging wire body 106 can be increased. When the rotating motor 209 operates, it can drive the rotating shaft 209a and the roller 2010 on its outer wall to rotate, so as to achieve the purpose of conveying the charging wire body 106.

[0035] The operation process of this embodiment is as follows: After the charging cable body 106 is plugged in, the clamping mechanism 104 is used to clamp and limit the tail end of the charging cable body 106. Then, the sliding surface survey mechanism 105 is slid to detect the wear condition of the outer wall of the charging cable body 106 between the inner wall of the test bench 1 and the clamping mechanism 104. Then, the surface survey mechanism 105 is slid close to the clamping mechanism 104. Then, the adjustment motor 201 is started, and the output shaft of the adjustment motor 201 rotates to drive the threaded rod 201a to rotate under the action of the coupling. Among them, positive threads and reverse threads are respectively arranged on both sides of the outer wall of the threaded rod 201a, and the positive threads and reverse threads are respectively engaged with the internal threads in the threaded holes on the front moving block 202 and the rear moving block 203. Therefore, when the threaded rod 201a rotates, it will drive the front moving block 202 and the rear moving block 203 to move in opposite or reverse directions, so as to adjust the distance between the front and rear support plates 204 through the front moving block 202 and the rear moving block 203, and make the front and rear rollers 2010 press on the outer side of the outer wall of the charging cable body 106. Among them, when the adjacent front and rear rollers 2010 apply force, the spring 207 will be compressed under the guiding action of the connecting rod 206, increasing the force applied by the front and rear rollers 2010 to the charging cable body 106. Then, the rotation motor 209 is started, and the output shaft of the rotation motor 209 rotates to drive the rotating shaft 209a to rotate through the coupling, and the rollers 2010 on its outer wall are used to rotate the rollers 2010 on its outer wall. The charging cable body 106 at the center position can be continuously conveyed inward through the front and rear rotating rollers 2010, and cooperate with the surface survey mechanism 105 to detect the entire charging cable body 106, which can be applicable to charging cable bodies 106 of various different lengths, and has a wide application range.

[0036] Embodiment 2

[0037] Please refer to Figure 2 and Figure 6 , on the basis of Embodiment 1, different from the first embodiment: A stable component 3 is provided. The stable component 3 includes a fixed shell 301 and a telescopic rod 302 fixedly connected to the center position at the top inside it. The telescopic end of the telescopic rod 302 is provided with a sliding plate 304, and the outer wall of the sliding plate 304 is slidably connected to the inner wall of the fixed shell 301, which solves the problem that the existing charging cable detection device limits the charging cable body through a screw and a limiting part during use, and this method is more cumbersome and time-consuming and laborious during the operation of the staff, resulting in low work efficiency.

[0038] Specifically, a tension spring 303 is sleeved outside the outer wall of the telescopic rod 302. The top and bottom ends of the tension spring 303 are respectively fixed to the inner top end of the fixed shell 301 and the upper surface of the sliding plate 304. A toothed plate 304a is fixedly connected to the center position of the bottom of the sliding plate 304. The bottom end of the toothed plate 304a penetrates through the through hole at the bottom of the fixed shell 301. Tooth discs 305 are arranged on both sides of the outer wall of the toothed plate 304a. A rotating rod 305a is fixedly connected to the center position of the inner wall of the tooth disc 305. The other end of the rotating rod 305a penetrates through the upper part of the outer wall of the clamping plate 306 and is connected to the bearing on the inner wall of the test bench 1. An arc groove is arranged at the center position of the inner wall of the clamping plate 306.

[0039] Furthermore, the telescopic rod 302 plays a role in limiting the tension spring 303. The sliding plate 304 can slide on the inner wall of the fixed shell 301 with high stability. Under the elastic performance of the tension spring 303, a force can be applied to the sliding plate 304. Gears are arranged on both sides of the outer wall of the toothed plate 304a and are meshed with the gears on the outer walls of the corresponding tooth discs 305 on both sides, playing a role in transmission. The tooth discs 305 and the clamping plate 306 are both located on the rotating rod 305a, and the three can rotate synchronously. When the tooth disc 305 rotates, it will drive the tooth disc 305 to rotate under the action of the rotating rod 305a, achieving the functions of opening and closing. The diameter of the arc groove on the inner wall of the clamping plate 306 is larger than the diameter of the charging wire body 106.

[0040] The operation process of this embodiment is as follows: When the staff needs to test the charging wire body 106, first push the toothed plate 304a downward. The downward movement of the toothed plate 304a will drive the sliding plate 304 to slide on the inner wall of the fixed shell 301, and pull the telescopic rod 302 and the tension spring 303. At the same time, the gears on the outer wall of the toothed plate 304a are meshed with the gears on the outer walls of the tooth discs 305 on both sides. Therefore, when the toothed plate 304a moves downward, a force will be applied to the tooth discs 305 on both sides, and the tooth discs 305 on both sides will rotate around the corresponding rotating rod 305a as the center, thereby rotating the clamping plate 306 on the outer wall of the rotating rod 305a outward to open. Then, the plug at one end of the charging wire body 106 can be inserted into the slot 103. Then, stop applying force to the toothed plate 304a. At this time, under the elastic performance of the tension spring 303, the sliding plate 304 can be pulled back to the upper part inside the fixed shell 301, and drive the toothed plate 304a to move upward, so that the tooth discs 305 on both sides rotate to the initial position, and the charging wire body 106 can be clamped outside through the arc grooves on the inner sides of the clamping plates 306 on both sides, and play a role in limiting it, increasing its stability during the test process, facilitating the staff to quickly limit and fix the charging wire body 106, saving time and effort, and having high work efficiency.

Obviously, many modifications and variations can be made according to the content of this specification.
