[0036] Example:
[0037] See also Figure 1 - Figure 8 A twisting and bending resistant power cord stretching device includes a power cord stretching test frame 101 set on a twisting and bending resistant machine 1, and a wire interface 102 with wires is evenly arranged at one end of the twisting and bending resistant machine 1. The outside of the wire of the wire interface 102 is provided with a positioning wire sleeve 2 and a wire clamp frame 201 for fixing and pulling the wire.
[0038] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6The twisting and bending resistant power cord stretching device of the present application is mainly composed of a twisting and bending resistant machine 1, a power cord stretching test stand 101 and a power cord stretching test stand 101, etc., so that the produced wires can pass through the performance test surface under various conditions to ensure the stability and reliability of the product in actual use. The wire performance is tested on the power cord stretching test stand 101 in combination with other accessories for different performance tests. Before the test, the power supply must be turned on. In actual applications, if all the wires are connected, a positioning wire sleeve 2 is provided in front of each wire interface 102. And it matches the wire clamp frame 201, wherein the positioning wire sleeve 2 is used to fix the wire inserted in the wire interface 102 on the outer wall of the anti-twisting bending machine 1. After the wire is fixed, the wire clamp frame 201 is used to allow the wire to be inside it, and then to pull the wire horizontally along the anti-twisting bending machine 1, so that the wire can be led out along the base of the anti-twisting bending machine 1. After combing, it is convenient to organize and save space. When the number of wires is large and long, the wires inserted into the output ports of each wire interface 102 are fixed and pulled separately to avoid problems such as damage caused by pulling after entanglement.
[0039] In some embodiments, the positioning wire sleeve 2 and the wire clamp frame 201 are configured to be elastic so that the wire can be better fixed after entering through the opening. The opening of the positioning wire sleeve 2 is configured to have an arc to facilitate the entry of the wire. The positioning wire sleeve 2 and the wire clamp frame 201 corresponding to the interface of the wire interface 102 are both configured on the same plane as the wire interface 102.
[0040] See also Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 In the present application, a mounting plate 3, a movable clamping frame 301 and a limiting plate 302 are provided to cooperate with each other to adjust the upper and lower positions of the positioning wire sleeve 2, wherein the limiting plate 302 is arranged directly below the wire interface 102 and is installed on the outer wall of the anti-twisting bending machine 1, and the mounting plate 3 is installed on the back of the positioning wire sleeve 2 and connected through the positioning structure, and the end of the mounting plate 3 facing the limiting plate 302 is fixedly connected with the movable clamping frame 301, and the limiting plate 302 is clamped on the movable clamping frame 301, and the movable clamping frame 301 is elastic, so that When clamping, the inner wall of the movable clamp frame 301 is tightly fitted with the outer surface of the limit plate 302. The anti-slip grooves are arranged inside the movable clamp frame 301, which can further increase the friction of the contact surface, making the connection between the movable clamp frame 301 and the limit plate 302 more stable. At the same time, after the movable clamp frame 301 is separated from the mounting plate 3, the movable clamp frame 301 can be clamped at different upper and lower positions of the limit plate 302 according to needs, so as to adjust the upper and lower heights of the positioning wire sleeve 2 arranged in the front to meet the usage requirements.
[0041] Among them, the positioning structure set in the present application is mainly composed of an inner clamping plate 4, a card plug-in unit 401 and a card socket 402 in combination, wherein the inner clamping plate 4 is installed at one end of the inner convex strip 202 facing the opening of the mounting plate 3, and it is elastic. When a force is applied to the inner clamping plate 4, the two ends of the inner clamping plate 4 are squeezed and deformed and fixed inside the mounting plate 3, and the card plug-in unit 401 is driven to be correspondingly inserted into the inside of the card socket 402 to ensure a stable connection, so that the positioning wire sleeve 2 can be installed on the mounting plate 3. At the same time, when the positioning wire sleeve 2 is damaged, the positioning wire sleeve 2 at that location can be replaced alone.
[0042] It should also be noted that positioning blocks 403 for limiting the upper and lower positions of the inner splint 4 on the mounting plate 3 are symmetrically installed on both sides of the upper and lower ends of the inner splint 4. The positioning blocks 403 are arranged in a circular shape. When the inner splint 4 is in the opening of the mounting plate 3, they are respectively located at the upper and lower ends of the mounting plate 3 for limiting the position. The positioning blocks 403 are designed to be made of rubber material. When the inner splint 4 is limited, a greater friction force can be generated between the upper and lower surfaces of the mounting plate 3 and the positioning blocks 403 to improve the stability of the connection.
[0043] The present application also provides an inner convex strip 202, which is evenly glued to the inner wall of the positioning wire sleeve 2, and is used to increase the friction of the contact surface when fixing the wire to prevent the wire contact surface from slipping.
[0044] See also Figure 2 , Figure 3 , Figure 4 and Figure 7 In the present application, a card slot 5 is also provided for separately fixing the wire clamp frame 201 provided on the torsion-resistant bending machine 1, wherein the number of the card slots 5 is not less than the wire clamp frame 201, which are respectively opened at the corresponding positions of the base of the torsion-resistant bending machine 1, and then the wire clamp frame 201 can be inserted into the card slot 5. This method facilitates the subsequent operations such as individual replacement of the wire clamp frame 201.
[0045] The present application also provides a positioning plate 501 and a clamping plate 502, wherein the positioning plate 501 is located below the front end of the wire clamping frame 201, and after the wire clamping frame 201 is inserted into the clamping slot 5, the positioning plate 501 can fit with the outer wall of the anti-twisting bending machine 1, wherein the clamping plate 502 and the positioning plate 501 are an integrated structural design with a certain degree of elasticity, and the positioning plate 501 can be fixed at the edge of the base of the anti-twisting bending machine 1, so as to further limit the wire clamping frame 201 during installation.
[0046] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments. Without departing from the principles, the embodiments of the present invention may be deformed or modified in any way.
