[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0026] like Figures 1-3 As shown, a power cord tension and torsion tester comprises a frame 1, a body 2 is arranged on the frame 1, a slide rail 4 is fixedly connected to the frame 1, a connecting plate 5 is slidably connected to the slide rail 4, a fixing plate 6 is fixedly connected to the connecting plate 5, a clamping assembly 7 is arranged on the fixing plate 6, the clamping assembly 7 comprises a sliding frame 71, an elastic member 72, a partition plate 73 and a slot 74, the sliding frame 71 is slidably connected to the connecting plate 5, the cross section of the sliding frame 71 is in a "U" shape, and the bottom of the sliding frame 71 is lower than the bottom of the fixing plate 6. The two elastic members 72 are fixedly connected to the fixed plate 6, the partition 73 is fixedly connected to the sliding frame 71, the partition 73 is located at the top of the sliding frame 71, the length of the partition 73 is equal to the inner wall width of the sliding frame 71, the two elastic members 72 are fixedly connected to the partition 73, the two elastic members 72 are symmetrical with the bidirectional screw 82 as the axis, the slot 74 is opened on the sliding frame 71, the slot 74 is located between the inner bottom wall of the sliding frame 71 and the bottom of the fixed plate 6, and a fixing component 8 is provided on the fixed plate 6.

[0027] The partition 73 is pressed down, and the sliding frame 71 moves downward accordingly, squeezing the elastic member 72. The slot 74 becomes larger as the sliding frame 71 moves downward, and the power cord is passed through the slot 74. When the connection between the power cord and the plug reaches the slot 74, the partition 73 is then released. Under the action of the elastic member 72, the sliding frame 71 is reset, and the slot 74 becomes smaller as the sliding frame 71 moves upward. The sliding frame 71 cooperates with the fixing plate 6 to clamp one end of the power cord connected to the plug, and then the other end of the power cord is connected to the body 2, so that the power cord is in a taut state.

[0028] The partition 73 not only strengthens the structural strength of the sliding frame 71, but also enables the user to apply pressure more evenly when pressing the partition 73 to release the power cord, avoiding damage caused by local stress concentration. In addition, the design of the partition 73 being the same length as the inner wall of the sliding frame 71 ensures that both sides of the sliding frame 71 can move synchronously when pressed, thus quickly and smoothly releasing or clamping the power cord.

[0029] Furthermore, as Figures 1-3 shown, the fixing component 8 includes a fixing block 81 and a bidirectional screw 82. The fixing block 81 is fixedly connected to the fixing plate 6. The height of the fixing block 81 is equal to the sum of the height of the rack 84 and the height of the threaded block 83. The bidirectional screw 82 is rotatably connected to the fixing block 81.

[0030] By precisely controlling the height of the fixing block 81, the rack 84 can stably maintain its connection with the threaded block 83 during movement, avoiding shaking or misalignment caused by height mismatch, thereby enhancing the stability and reliability of the entire fixing component 8.

[0031] Furthermore, as Figures 1-3 shown, the fixing component 8 further includes threaded blocks 83 and a knob 86. The two threaded blocks 83 are respectively threadedly connected to both ends of the bidirectional screw 82. The two threaded blocks 83 are symmetrical about the partition 73. The knob 86 is fixedly connected to the bidirectional screw 82. The knob 86 is located at one end of the bidirectional screw 82 close to the fixing block 81.

[0032] The threaded blocks 83 are respectively threadedly connected to both ends of the bidirectional screw 82. When the bidirectional screw 82 rotates, due to the locking effect of the thread, the two threaded blocks 83 will move towards or away from each other along the axis of the screw. This linear motion mode ensures the stability and accuracy of the movement, thereby further enhancing the stability of the power cord during the test.

[0033] Furthermore, as Figures 1-3 shown, the fixing component 8 further includes racks 84. The two racks 84 are slidably connected to the fixing plate 6. The lengths of the two racks 84 are equal to the width of the fixing plate 6. The two racks 84 are symmetrical about the partition 73. The two racks 84 are respectively fixedly connected to the two threaded blocks 83.

[0034] Furthermore, as Figures 1-3 shown, the fixing component 8 further includes tooth blocks 85. A plurality of tooth blocks 85 are fixedly connected to the sliding frame 71. The tooth blocks 85 are linearly arrayed on the sliding frame 71. When the rack 84 meets the sliding frame 71, the rack 84 meshes with the tooth blocks 85.

[0035] Rotate the bidirectional screw 82. Since the two threaded blocks 83 are respectively threadedly connected to both ends of the bidirectional screw 82, the two threaded blocks 83 move towards each other, driving the two racks 84 to move towards each other. The racks 84 move and mesh with the tooth block 85 during the movement. The sliding frame 71 is fixed. At this time, the clamping assembly 7 firmly clamps the power cord, preventing the power cord from falling off due to the shaking of the machine during the test, thus affecting the test process.

[0036] Since the lengths of the two racks 84 match the width of the fixed plate 6 and are symmetrical about the partition plate 73, the stability of the racks 84 during the movement is ensured. When the bidirectional screw rotates, the two racks 84 can move towards the center synchronously and smoothly, meshing tightly with the tooth block 85, thereby fixing the power cord more firmly and improving the overall stability during the test.

[0037] The symmetrical layout of the two racks 84 enables uniform force application to the sliding frame 71 when they mesh with the tooth block 85. This uniform force not only helps prevent the power cord from shifting or being damaged due to uneven force during the test, but also ensures the accuracy and reliability of the test results.

[0038] Furthermore, as Figure 1 shown, the frame 1 is provided with universal wheels 3. The four universal wheels 3 are fixedly connected to the bottom of the frame 1. The universal wheels 3 are linearly arrayed at the bottom of the frame 1. Clips are provided on all four universal wheels 3 for the movement and fixation of the device.

[0039] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacements of the above technical features. Matters not covered in the present utility model belong to the common general knowledge of those skilled in the art.
