[0002] A tensile tester is an instrument for testing tensile strength. It is mainly used for tensile, compression, bending, peeling, shearing, and tearing tests on non-metallic materials such as tapes, rubber, plastics, foam, waterproof materials, wires and cables, textiles, ropes, and non-woven fabrics, as well as metal wires, foils, sheets, and rods. It is a powerful tool to help the industry improve quality.

[0003] The existing Chinese patent with publication number CN219625220U discloses a yarn tensile strength tester, including a base plate, a control box and a tension box fixedly installed at both ends of the top surface of the base plate, and two yarn clamping frames provided on the front surface of the tension box; a protective component, including a fixing frame, which is fixedly installed on the front surface of the tension box, and a protective plate is provided inside the fixing frame; and an auxiliary illumination component, including a lamp plate, with a mounting groove on one side surface of the lamp plate, and a first illumination bulb and a second illumination bulb arranged inside the mounting groove, and the lamp plate is electrically connected to the control box.

[0004] Regarding the aforementioned technologies, the inventors have discovered at least the following problems: In the aforementioned technologies, the use of a sliding protective plate to protect the test wires can prevent broken wires from injuring the test personnel. However, since the protective plate needs to slide upwards when opening, space needs to be reserved above the device during installation for the protective plate to slide up and down. This results in the device occupying a large space, making it difficult to use in situations where ample space is not available, thus reducing the device's versatility. Utility Model Content

[0005] The purpose of this invention is to provide a wire harness tensile testing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wire harness tensile testing machine, comprising a main body and a protective component, wherein the protective component is disposed on the front of the main body, a sliding groove is provided inside the main body, a hydraulic press is fixedly installed on the inner top wall of the sliding groove, a slider is fixedly connected to the lower end of the hydraulic press, and wire harness clamps are fixedly installed on the bottom of the main body and one side of the slider.

[0007] The protective assembly includes vertical plates fixedly connected to both sides of the main body of the equipment. A drum is rotatably mounted on the upper end of the vertical plate. A spiral spring is installed inside the drum. A transparent protective film is wound around the surface of the drum. A connecting rod is fixedly connected to the end of the transparent protective film. One end of the connecting rod is threaded to a screw. The screw is rotatably mounted on the outside of one of the vertical plates. A motor for driving the screw to rotate is fixedly mounted on the vertical plate.

[0011] In a preferred embodiment, the other end of the connecting rod is slidably sleeved on the guide rod, and the guide rod is fixedly installed on the outside of another vertical plate.

[0012] In a preferred embodiment, a plurality of vertically distributed lighting lamps are fixedly connected to the inner side of the vertical plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This wire harness tensile testing machine, through the inclusion of protective components, allows for the following features: During testing, a motor can be started to rotate the screw, which in turn drives the connecting rod to slide downwards along the guide rod. This causes the connecting rod to pull the transparent protective film on the drum, covering the outside of the main body of the equipment and protecting the yarn area during testing. This prevents broken yarn from injuring the testing personnel. After testing, the motor can be started to raise the connecting rod, and the drum automatically rewinds the transparent protective film under the action of the spiral spring. This design does not occupy extra space and improves the versatility of the equipment.

[0015] This wire harness tensile testing machine, through the setting of a lighting lamp, can illuminate the yarn during testing, making it easier to observe the yarn. Attached Figure Description

[0020] The present invention will be further described below with reference to the embodiments.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figure 1-3 This utility model provides a wire harness tensile testing machine, including a main body 1 and a protective component 2. The protective component 2 is disposed on the front of the main body 1. A slide groove 11 is formed inside the main body 1. A hydraulic press 12 is fixedly installed on the inner top wall of the slide groove 11. A slider 13 is fixedly connected to the lower end of the hydraulic press 12. Wire harness clamps 14 are fixedly installed on the bottom of the main body 1 and on one side of the slider 13. A scale 15 is provided on one side of the main body 1 located in the slide groove 11. The machine is equipped with the slide groove 11, hydraulic press 12, slider 13, wire harness clamp 14, and scale 15. When performing a tensile test on the yarn, both ends of the yarn can be clamped and fixed by two wire harness clamps 14. Then, the hydraulic press 12 is started to drive the slider 13 to slide upward along the slide groove 11, so that the slider 13 drives the wire harness clamps 14 above to rise. The two wire harness clamps 14 gradually move away from each other, thereby stretching the yarn. Observe the scale corresponding to the wire harness clamps 14 above on the scale 15 to determine the stretching length of the yarn. When the yarn reaches the preset scale, if the yarn has broken, it means that the yarn tensile strength is poor. If the yarn has not broken, it means that the yarn tensile strength meets the standard.

[0023] Specifically, the wire harness clamp 14 includes a fixed frame 141, a first clamping plate 142 fixedly connected to the inner wall of the fixed frame 141, a clamping rod 143 threadedly connected to one side of the fixed frame 141, a second clamping plate 144 rotatably connected to one end of the clamping rod 143, and anti-slip pads 145 fixedly connected to the sides of the first clamping plate 142 and the second clamping plate 144 that are close to each other. With the wire harness clamp 14, the wire harness can be placed in the fixed frame 141, and the clamping rod 143 can be rotated to bring the second clamping plate 144 closer to the first clamping plate 142. The anti-slip pads 145 on the surfaces of the first clamping plate 142 and the second clamping plate 144 are used to clamp and fix the wire harness.

[0024] Specifically, the protective component 2 includes vertical plates 21 fixedly connected to both sides of the main body 1. A drum 22 is rotatably mounted on the upper end of the vertical plates 21. A spiral spring is installed inside the drum 22. A transparent protective film 23 is wound around the surface of the drum 22. A connecting rod 24 is fixedly connected to the end of the transparent protective film 23. One end of the connecting rod 24 is threadedly connected to a screw 25. The screw 25 is rotatably mounted on the outside of one of the vertical plates 21. A motor 26 for driving the screw 25 to rotate is fixedly mounted on the vertical plate 21. The other end of the connecting rod 24 is slidably sleeved on a guide rod 27. The guide rod 27 is fixedly mounted on the other vertical plate 21. On the outside, through the setting of protective component 2, during testing, motor 26 can be started to drive screw 25 to rotate. Screw 25 drives connecting rod 24 to slide downward along guide rod 27, so that connecting rod 24 pulls transparent protective film 23 on drum 22, so that transparent protective film 23 covers the outside of the main body of equipment 1, protecting the yarn area during testing and preventing broken yarn from injuring the test personnel. After the test, motor 26 can be started to drive connecting rod 24 to rise. Drum 22 automatically winds up transparent protective film 23 under the action of spiral spring, without occupying extra space and improving the versatility of equipment.

[0025] Furthermore, several vertically distributed lighting lamps 28 are fixedly connected to the inner side of the vertical plate 21. The lighting lamps 28 can illuminate the yarn under test, making it easier to observe the yarn.

[0026] The working principle and usage process of this utility model are as follows: First, when conducting a tensile test on the yarn, the two ends of the yarn can be clamped and fixed by two wire harness clamps 14 respectively. Then, the motor 26 can be started to drive the screw 25 to rotate. The screw 25 drives the connecting rod 24 to slide downward along the guide rod 27, so that the connecting rod 24 pulls the transparent protective film 23 on the drum 22, so that the transparent protective film 23 covers the outside of the main body 1 of the equipment and protects the yarn area under test.

[0027] Then, the hydraulic press 12 is started to drive the slider 13 to slide upward along the slide groove 11, so that the slider 13 drives the upper wire harness clamp 14 to rise. The two wire harness clamps 14 gradually move away from each other, so that the yarn can be stretched. Observe the scale corresponding to the upper wire harness clamp 14 on the scale 15 to judge the stretching length of the yarn. When the yarn reaches the preset scale, if the yarn has broken, it means that the yarn tension is poor. If the yarn has not broken, it means that the yarn tension meets the standard. After the test, the motor 26 can be started to drive the connecting rod 24 to rise. The drum 22 automatically winds up the transparent protective film 23 under the action of the spiral spring, without occupying extra space and improving the versatility of the equipment.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
