DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A vehicle harness tensile test tool comprises a base 1, a fixing plate 2 fixedly mounted at one end of the base 1, and a stretching seat 3 arranged at one end of the base 1 away from the fixing plate 2. An operation panel 11 is fixedly mounted at the end of the base 1 away from the fixing plate 2. A fixing mechanism 5 is arranged on the fixing plate 2. A slot 31 is provided on the stretching seat 3. A slide plate 4 is symmetrically arranged in the slot 31. A clamping seat 41 is fixedly mounted on the slide plate 4. A driving mechanism 32 corresponding to the slide plate 4 is arranged in the slot 31. The slide plate 4 and the clamping seat 41 can be controlled by the driving mechanism 32, so that the end of the harness can be fixed between the clamping seats 41, ensuring that the end of the harness is fixed more simply and firmly.

[0023] Reference Figure 2 The driving mechanism 32 includes a gear 321 rotatably mounted in the slot 31, a rack 322 fixedly mounted at the end of the slide plate 4 away from the clamping seat 41 and meshing with the gear 321, and a driving screw 323 fixedly mounted at the end of the rack 322 away from the gear 321. The end of the driving screw 323 away from the rack 322 axially penetrates the stretching seat 3 and is threadedly connected to the penetration. The rotation of the driving screw 323 can drive the rack 322 to slide, thereby driving the two slide plates 4 and the clamping seat 41 to slide in opposite directions through the gear 321.

[0024] Reference Figure 2 A rotating handle 3231 is fixedly installed on one end of the driving screw rod 323 located outside the stretching seat 3. The driving screw rod 323 can be operated by the rotating handle 3231.

[0025] Reference Figure 1 The opposite sides of the two clamping seats 41 are arranged in a corresponding S-shape, and the opposite sides of the two clamping seats 41 are provided with a plurality of evenly distributed convex hulls. The clamping surface of the clamping seat 41 is arranged in an S-shape and the convex hulls are provided so that the end of the wire harness is clamped more firmly.

[0026] Reference Figure 3The fixing mechanism 5 includes a rotating disk 51 mounted on the fixing disk 2 and a plurality of slots 52 of different sizes arranged in a circular array on the rotating disk 51. The rotating disk 51 can be rotated on the fixing disk 2 to adjust the positions of the slots 52 of different sizes so as to fix wire harnesses of different sizes.

[0027] Reference Figure 3 A plurality of vertical plates 21 distributed in a linear array are fixedly mounted on the fixed plate 2, and a bayonet 211 is provided on the vertical plate 21. The bayonet 211 on the vertical plate 21 can be engaged with the connector at the end of the wire harness, and different vertical plates 21 can be selected to adjust the test length of the wire harness, which is more convenient to use.

[0028] The specific working principle of the utility model is as follows:

[0029] First, the tested wire harness needs to be fixed. When fixing one end, the turntable 51 can be rotated so that the slot 52 of the corresponding size can be flush with the slot 211 on the vertical plate 21. The vertical plate 21 can be selected according to the length of the wire harness test, and the connector at the end of the wire harness is snapped into the slot 211 at the corresponding position. The wire harness can pass through the slot 52 to fix one end. When fixing the other end, the end of the wire harness can be placed between the two clamping seats 41. When the handle 3231 is rotated, the drive screw 323 is driven to rotate, and the drive screw 323 and the penetration screw 323 are connected. It is threadedly connected, so when it rotates, it can drive the rack 322 to slide. When the rack 322 slides, it can drive the two slides 4 and the clamping seat 41 to slide in opposite directions through the gear 321, so as to clamp the end of the wire harness. The clamping surface of the clamping seat 41 is S-shaped, which ensures that the wire harness is clamped more firmly. At the same time, the convex bump can increase the friction and further improve the stability. After the wire harness is fixed, the stretching seat 3 can be opened to test the stretching performance of the wire harness. The working principle and connection method of the stretching seat 3 are existing mature technologies and will not be elaborated here.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
