[0029] A power cord bending test device, comprising:

[0030] The frame 1 has a motor 9 fixedly mounted on the top of one side of the frame 1, and the driving end of the motor 9 passes through one side of the frame 1 and extends to the top of the inside of the frame 1. The driving end of the motor 9 is fixedly mounted with a drum 2. Circular baffles 3 are fixedly mounted on both ends of the drum 2. A plurality of movable plates 8 are arranged between the two circular baffles 3. An adjusting screw 15 is rotatably mounted inside the drum 2. Left-handed and right-handed threads are symmetrically distributed on both sides of the outer wall of the adjusting screw 15. Symmetrically distributed adjusting blocks 14 are sleeved on both sides of the outer wall of the adjusting screw 15.

[0031] The outer wall of the drum 2 is provided with a plurality of through slots 6 corresponding in position and number to the movable plates 8. Connecting rods 7 are hingedly connected to the four surfaces of the adjusting block 14. The ends of the connecting rods 7 away from the adjusting block 14 pass through the through slots 6 at corresponding positions and are hingedly connected to the inner surfaces of the corresponding movable plates 8. The connecting rods 7 are slidably connected to the through slots 6.

[0032] One end of the adjusting screw rod 15 passes through the inner wall of the rotating drum 2 and extends to one side of a circular baffle 3. One end of the adjusting screw rod 15 is fixedly installed with a rotating plate 4. Several fixing cylinders 10 are fixedly installed on the bottom of the inside of the frame 1 and the outer wall of the rotating drum 2. The fixing cylinders 10 are threadedly connected with bolts 16 through threaded holes opened on their outer walls.

[0033] The rotating plate 4 is threadedly connected to a threaded column 11 through a threaded hole formed thereon, and a handle 5 is fixedly mounted on one end of the threaded column 11 . A plurality of positioning grooves 17 are formed on one side of a circular baffle 3 , and the positioning grooves 17 are threadedly connected to the threaded column 11 .

[0034] In one embodiment, limiting blocks 12 are fixedly installed on both sides of the movable plate 8, and limiting grooves 13 corresponding to the position and number of the movable plate 8 are opened on the opposite surfaces of the two circular baffles 3, and the limiting grooves 13 are slidably connected to the limiting blocks 12 to achieve stable position adjustment of the movable plate 8.

[0035] In one preferred embodiment, a threaded hole adapted to the adjusting screw rod 15 is provided on one side of the adjusting block 14 , and the adjusting block 14 is threadedly connected to the adjusting screw rod 15 through the threaded hole provided on one side of the adjusting block 14 .

[0036] In one embodiment, there are two bolts 16 on the fixing tube 10 , and the positions of the two bolts 16 are asymmetrically arranged, which can fix the power cord in the fixing tube 10 in a bite state, making the power cord more firmly fixed.

[0037] In one preferred embodiment, the movable plate 8 is in the shape of an arc plate, so that the movable plate 8 can better fit the shape of the power cord, thereby providing uniform and stable support during the bending test.

[0038] The working principle of the present invention is as follows: the electrical components appearing in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for controlling a computer, etc., and the existing disclosed power connection technology will not be repeated in this article. When in use, first fix one end of the power cord on the fixed cylinder 10 at the bottom inside the frame 1. The specific operation steps are to directly insert one end of the power cord into the inside of the fixed cylinder 10, and then tighten the bolt 16 on the fixed cylinder 10 to firmly fix the power cord inside the fixed cylinder 10. In the same way, fix the other end of the power cord on the fixed cylinder 10 on the outer wall of the rotating cylinder 2, and then according to the specifications of the power cord, first drive the adjusting screw 15 to rotate through the rotating plate 4, and through the thread transmission of the left-handed thread and the right-handed thread on the adjusting screw 15, the two groups of adjusting blocks 14 on the outer wall of the adjusting screw 15 are simultaneously moved relative to or oppositely. When the adjusting blocks 14 move relative to each other, the two connected The angle between the rods 7 is reduced, and the four movable plates 8 are pushed to expand outward at the same time to adjust the position of the movable plate 8. After the position is adjusted, the drum 2 can be driven to rotate by the driving end of the motor 9. The rotation of the drum 2 will reel the power cord into the outer wall of the movable plate 8 through the fixed cylinder 10 on its outer wall and perform a tensile test on the power cord at the same time. After the test is completed, the direction of the driving end of the motor 9 is changed to drive the drum 2 to flip, and the power cord wrapped around the outer wall of the movable plate 8 is removed. Finally, the bolts 16 on the fixed cylinder 10 are loosened to complete the disassembly of the power cord on the device, and the bending tensile test of the next batch of power cords can be carried out. The device can arbitrarily change the position of the movable plate 8 through the adjustability of the four movable plates 8 on the outside of the drum 2, and the adjustment method for the movable plate 8 is simple, which is convenient for people to use, so that the curvature of the power cord can be adjusted according to the different specifications of the power cord, and the applicability is wider.

[0039] In the process of adjusting the position of the movable plate 8, it is achieved by rotating the rotating plate 4. Before rotating the rotating plate 4, the handle 5 is rotated first. The rotation of the handle 5 drives the threaded column 11 to rotate. The threaded column 11 is threadedly connected with the rotating plate 4 and the positioning groove 17, and the threaded column 11 is screwed out from the inside of the corresponding positioning groove 17. At this time, the rotating plate 4 will lose the limit of the threaded column 11 and the positioning groove 17, and the rotating plate 4 can be freely rotated to complete the position adjustment of the movable plate 8. After the position is adjusted, the threaded column 11 is screwed into the inside of the corresponding positioning groove 17 to lock the position of the rotating plate 4, so as to avoid the reversal of the adjusting screw rod 15 during the power cord experiment, which causes the movable plate 8 to be displaced, thereby affecting the accuracy of the experimental results.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
