[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 5 This utility model provides a technical solution: a vehicle collision deformation measuring device, including a base 1 and a measuring instrument 3. A lifting assembly is provided at the top of the base 1, and a frame 2 is provided at the front end of the lifting assembly. A sliding assembly is provided inside the frame 2, and two sliding plates 7 are provided on the sliding assembly. A fixing rod 8 is provided on the side of each sliding plate 7 that is close to each other. A fixing block 5 is provided on the rear side of the measuring instrument 3, and fixing holes 6 are provided on both sides of the outer wall of the fixing block 5. Wheels 4 are provided at the four corners of the bottom of the base 1. The sliding assembly drives the two sliding plates 7 and the two fixing rods 8 simultaneously towards the frame. The inner cavity of the 2 slides, thereby allowing the two fixing rods 8 to be detachably inserted into the inner cavities of the two fixing holes 6, thus fixing the fixing block 5 and completing the installation of the measuring instrument 3. This facilitates the assembly and disassembly of the measuring instrument 3. Through the setting of the lifting component, the lifting plate 19 can drive the frame 2, the fixing block 5 and the measuring instrument 3 to slide up and down, thereby realizing the height adjustment of the measuring instrument 3. It does not require the user to hold it, which solves the problem that the existing automobile collision deformation measuring device requires the user to hold it when using it, and is complicated and inconvenient to operate.

[0022] In this embodiment, wheel 4 is a self-locking omnidirectional wheel, which facilitates the movement and positioning of the device.

[0023] In this embodiment, the lifting assembly includes a guide rod 14, a top plate 15, a motor 16, a screw 17, and a lifting plate 19. The guide rod 14 is located at the top of the base 1, the top plate 15 is located at the top of the guide rod 14, the motor 16 is located at the top of the top plate 15, one end of the screw 17 is rotatably connected to the top of the base 1 via a bearing, and the other end of the screw 17 is fixedly connected to the output end of the motor 16. The lifting plate 19 is screwed onto the outer wall of the screw 17 and slidably sleeved onto the outer wall of the guide rod 14. The lifting plate 19 is fixedly connected to the frame 2. The motor is started. 16. The motor 16 drives the screw 17 to rotate. Under the action of the rotational force of the screw 17's outer thread, when the screw 17 rotates, the lifting plate 19 can slide up and down under the limiting action of the guide rod 14. The lifting plate 19 can drive the frame 2, the fixed block 5, and the measuring instrument 3 to slide up and down, thereby realizing the height adjustment of the measuring instrument 3. It does not require the user to hold it, which solves the problem that the existing automobile collision deformation measuring device requires the user to hold it when using it, and the operation is complicated and inconvenient.

[0024] In this embodiment, a spring 18 is sleeved on the outer wall of the screw 17. The upper and lower ends of the spring 18 are fixedly connected to the lifting plate 19 and the base 1, respectively. By setting the spring 18, the mechanical gap between the inner wall thread of the lifting plate 19 and the outer wall thread of the screw 17 can be eliminated, thereby improving the stability of the lifting assembly operation.

[0025] In this embodiment, the sliding assembly includes a lead screw 9, a knob 10, sliders 11, and a limiting assembly. One end of the lead screw 9 is rotatably connected to the left side of the inner cavity of the frame 2 via a bearing, and the other end of the lead screw 9 extends to the right end of the frame 2 and is fixedly connected to the knob 10. Two sliders 11 are screwed onto the left and right sides of the outer wall of the lead screw 9, respectively. The limiting assembly is located on the rear side of the inner cavity of the frame 2 and is fixedly connected to the two sliders 11. The two sliders 11 are fixedly connected to the two slide plates 7, respectively. Rotating the knob 10 causes the knob 10 to drive the lead screw 9 to rotate, thereby causing the threads on the left and right sides of the outer wall of the lead screw 9 to generate relative thread rotation force. Under the limiting action of the limiting groove 12 and the limiting block 13, the two sliders 11 slide relative to each other simultaneously, causing the two slide plates 7 to drive the two fixed rods 8 to slide simultaneously toward the middle of the inner cavity of the frame 2, so that the two fixed rods 8 can be detachably inserted into the inner cavity of the two fixed holes 6, thereby fixing the fixed block 5 and completing the installation of the measuring instrument 3, which facilitates the assembly and disassembly of the measuring instrument 3.

[0026] In this embodiment, the threads on the left and right sides of the outer wall of the lead screw 9 are arranged opposite to each other, so that when the lead screw 9 rotates, the left and right sides of its outer wall generate relative thread rotation force, so that the two sliders 11 slide relative to each other simultaneously under the limiting action of the limiting groove 12 and the limiting block 13.

[0027] In this embodiment, the limiting component includes a limiting groove 12 and limiting blocks 13. The limiting groove 12 is opened on the rear side of the inner cavity of the frame 2. Both limiting blocks 13 are slidably embedded in the inner cavity of the limiting groove 12 and are fixedly connected to two sliders 11 respectively. Under the joint action of the limiting groove 12 and the limiting blocks 13, the sliders 11 can be prevented from rotating with the lead screw 9 when the lead screw 9 rotates, which improves the stability of the sliding component during use. The inner cavity of the limiting groove 12 and the outer wall of the limiting block 13 are adapted to each other and are both in the shape of "T", which can keep one end of the limiting block 13 embedded in the inner cavity of the limiting groove 12, which improves the stability of the limiting component during use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
