[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for testing the tensile strength of electrical wires.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for testing the tensile strength of electrical wires includes a protective assembly.

[0008] As a further embodiment of this utility model: the fixing component includes a mounting base, which is fixed to the end of the hydraulic telescopic rod. A fixing shaft is provided on one side of the mounting base, and a winding wheel is rotatably mounted through the fixing shaft. The winding wheel is arranged in a circle and has multiple sets of positioning holes. The mounting base has multiple sets of limiting holes whose positions and sizes are adapted to the positioning holes, and a second fixing pin is installed through the limiting holes.

Detailed Implementation

[0023] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] Example 1

[0026] A device for testing the tensile strength of electrical wires, such as Figures 1-4 As shown, the protective assembly includes a workbench 1. A protective box 9 is bolted to the top outer wall of the workbench 1. A fixing frame 10 is installed on the outer wall of the protective box 9. Two sets of fixing frames 10 are provided and installed on both sides of the protective box 9. An adjusting motor 11 is bolted to one side of the fixing frame 10. An installation shaft 8 is connected to one side of the adjusting motor 11. One end of the installation shaft 8 is rotatably inserted through the fixing frame 10. A protective door 15 is installed at one end of the installation shaft 8. The protective door 15 has two sets of slots. Two sets of locking blocks 14 are installed on one side of the protective box 9. The position and size of the locking blocks 14 are adapted to the slots of the protective door 15. A fixing hole is provided on one side of the locking block 14, and a first fixing pin 13 is provided through the fixing hole. A testing component for testing tensile properties is provided on one side of the protective box 9.

[0027] During use, the tensile strength of the wire can be tested using the testing component. Before the test begins, the installation shaft 8 is rotated by adjusting the motor 11. The installation shaft 8 drives the protective door 15 to rotate. The rotation of the protective door 15 can close the protective box 9. After closing, the locking block 14 passes through the slot of the protective door 15. After passing through, the first fixing pin 13 is inserted through the fixing hole of the locking block 14 to further restrict the protective door 15 and keep it closed. This can provide effective protection during testing and prevent the wire from injuring the surrounding staff when it breaks. By effectively restricting the protective door 15, it can prevent the protective door 15 and the protective box 9 from not closing securely, which could cause debris to splash out and injure the staff.

[0028] The detection component includes a hydraulic telescopic rod 12, which is fixed to the outer wall of one side of the protective box 9 by bolts. The telescopic end of one side of the hydraulic telescopic rod 12 is slidably connected to the inside of the protective box 9. A fixing component for fixing wires is provided at the end of the hydraulic telescopic rod 12. A tension gauge 21 is provided on the inner wall of one side of the protective box 9, and a fixing ring is provided on one side of the tension gauge 21.

[0029] In use, one end of the wire to be tested can be fixed by the fixing ring of the tension gauge 21, and the other end of the cable can be fixed to the fixing component. After the fixing is completed, the fixed wire is moved away from the tension gauge 21 by the hydraulic telescopic rod 12 to pull the wire. The tension sensor of the tension gauge 21 can detect the tension, thereby testing the tensile performance of the wire and testing whether its quality meets the standard.

[0030] The fixing component includes a mounting base 17, which is fixed to the end of the hydraulic telescopic rod 12 by bolts. A fixing shaft 20 is provided on one side of the mounting base 17, and a winding wheel 18 is rotatably mounted through the fixing shaft 20. The winding wheel 18 is arranged in a circle and has multiple sets of positioning holes. The mounting base 17 has multiple sets of limiting holes whose positions and sizes are adapted to the positioning holes. A second fixing pin 19 is installed through the limiting holes.

[0031] When in use, after fixing one end of the wire to the pull ring of the tension gauge 21, the other end can be wound up and fixed to the winding wheel 18. The end can be knotted to prevent the wire from loosening after fixing. By controlling the rotation of the winding wheel 18, the wire can be wound up to keep it tight, which facilitates tensile testing. This avoids the wire being too loose after fixing, which would reduce the stroke of the hydraulic telescopic rod 12 and the mounting base 17 and prevent the wire from being unable to apply a large tensile force. After adjusting the tightness by winding, align the positioning hole of the winding wheel 18 with the limiting hole of the mounting base 17. After alignment, insert the second fixing pin 19 to restrict the winding wheel 18 and prevent it from rotating during testing, which would affect the tensile performance test.

[0032] To support the device, such as Figure 2 As shown, the bottom outer wall of the workbench 1 is fixed with support legs 4 by bolts, and foot pads 3 are provided at the bottom of the support legs 4;

[0033] During use, the support legs 4 and foot pads 3 work together to support the device, thereby maintaining its stability during use.

[0034] To facilitate observation during testing, such as Figure 1 As shown, a transparent observation window 16 is provided on one side of the protective door 15, and the observation window 16 is covered with an explosion-proof film;

[0035] During use, the testing situation inside the protective box 9 can be observed through the transparent observation window 16. The explosion-proof film can provide protection and prevent the observation window 16 from being broken by debris or broken wires, causing fragments to fly.

[0036] To facilitate the inspection of the wires, such as Figure 1 , 2As shown, a support frame 7 is fixed to the top outer wall of the workbench 1 by bolts, a camera 6 is fixed to one side of the support frame 7 by bolts, and a fill light is installed on one side of the camera 6.

[0037] When in use, the wire can be placed under the camera 6, and the wire can be photographed through the camera 6. By magnifying the photographed image, the wire can be observed in detail to check for any defects. A supplementary light can be used to provide supplementary lighting in low light conditions, making it easier to photograph the wire.

[0038] For ease of control of the device, such as Figure 1 As shown, a control panel 5 is fixed to the top outer wall of the workbench 1 by bolts, and the control panel 5 is covered with a protective film.

[0039] In use, the control panel 5 is connected to the various components of the device via wiring. The device can be easily controlled through the control panel 5, and the image captured by the camera 6 can be displayed through the control panel 5, thereby allowing for the inspection of the wiring.

[0040] Example 2

[0041] To prevent displacement of the device, refer to Figure 2 A device for testing the tensile strength of electrical wires. This embodiment makes the following improvements compared to embodiment 1: a pad 2 is installed at the bottom of the foot pad 3. The pad 2 is made of rubber material and has annular patterns at the bottom.

[0042] When in use, the rubber pad 2, in conjunction with the annular pattern on its bottom, can effectively increase the friction when in contact with the ground, thereby increasing anti-slip properties and preventing unnecessary sliding displacement of the device.

[0043] The above description is only a preferred embodiment of the present utility model. For parts that do not require creative effort in circuit control, signal control and transmission, please refer to the prior art. However, the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
