DETAILED DESCRIPTION
[0024] The embodiments of the present application will be described in detail below with the accompanying drawings and examples, so that the realization process of how to apply technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.
[0025] Please refer to Figures 1 to 5 The embodiments of the present application provide a telescopic reference device for automobile gauge, which comprises a fixing structure, a supporting structure and an adjusting structure. The supporting structure for supporting the parts to be detected is installed on the fixing structure, and the adjusting structure can switch the supporting structure between the working state and the non-working state.
[0026] Among them, the fixing structure provides the installation basis for the whole device, and fixes the device on the detection tool. The supporting structure is responsible for supporting the parts to be detected, and ensures the stability of the parts during the detection process. The adjusting structure changes the position or state of the supporting structure through specific operation, so as to switch between the working state and the non-working state, and adapt to different detection requirements.
[0027] In the embodiments, the fixing structure comprises a mounting seat 1, the top of the mounting seat 1 is provided with a U-shaped groove 102 for installing the adjusting structure, and the upper end of the mounting seat 1 is provided with a mounting hole. A bushing 2 can be detachably installed in the mounting hole. The mounting seat 1 is the main body of the fixing structure, which provides installation space and movement range for the adjusting structure through the U-shaped groove 102, so that the adjusting structure can perform corresponding operation therein. The mounting hole is used for installing the bushing 2, and the bushing 2 can be detachably installed, which is convenient for replacement or maintenance when needed. Meanwhile, the bushing 2 also provides a guiding function for the guide pin 3 of the supporting structure.
[0028] In the embodiments, the supporting structure comprises a guide pin 3, a locking screw 4 and a support pad 5. One end of the guide pin 3 penetrates through the bushing 2 and can extend into the U-shaped groove 102, and the support pad 5 is fixedly installed on the end of the guide pin 3 away from the U-shaped groove 102 through the locking screw 4. Under the guiding action of the bushing 2, the guide pin 3 can move along a certain direction. When the guide pin 3 moves, the support pad 5 fixed on one end of the guide pin 3 also moves. The locking screw 4 is used to firmly fix the support pad 5 on the guide pin 3, so as to ensure that the support pad 5 will not loosen when supporting the parts to be detected.
[0029] In this embodiment, the adjusting structure includes an adjusting pad 6, a compression spring 7, a gasket 8, and an internal hexagonal screw 9. One end of the internal hexagonal screw 9 is slidably inserted into the U-shaped groove 102 from the side of the mounting base 1 away from the bushing 2 and is fixedly connected with the guide pin 3. The compression spring 7 and the gasket 8 are both sleeved on the internal hexagonal screw 9. One end of the compression spring 7 abuts against the side of the mounting base 1 away from the bushing 2, and the other end of the compression spring 7 abuts against one side of the gasket 8. The adjusting pad 6 is slidably arranged in the U-shaped groove 102. One side of the adjusting pad 6 is in sliding contact with the end of the guide pin 3 away from the bushing 2. The side of the adjusting pad 6 in contact with the guide pin 3 is provided with a guide inclined surface 602.
[0030] When an external force is applied to the adjusting structure, the compression spring 7 will be compressed or stretched. The adjusting pad 6 slides in the U-shaped groove 102, and the guide inclined surface 602 is in contact with the guide pin 3. When the adjusting pad 6 slides, the guide inclined surface 602 pushes the guide pin 3 to move in the bushing 2 in a direction away from or close to the adjusting pad 6, thereby realizing the switching of the working state and the non-working state of the supporting structure.
[0031] In this embodiment, a waist hole 601 is formed in the adjusting pad 6, and the end of the internal hexagonal screw 9 close to the guide pin 3 penetrates through the waist hole 601.
[0032] Working principle: The waist hole 601 provides a certain movement space for the internal hexagonal screw 9, so that the adjusting pad 6 is more stable and smooth during sliding, and the normal operation of the adjusting structure is ensured.
[0033] In this embodiment, one end of the adjusting pad 6 is fixedly installed with a handle 10. The handle 10 provides an easy-to-operate part for the operator. By pulling or pushing the handle 10, the adjusting pad 6 can be conveniently slid in the U-shaped groove 102, thereby driving the guide pin 3 and the supporting pad 5 to move and realizing the switching of the working state of the supporting structure.
[0034] In this embodiment, the upper end of the mounting base 1 is provided with a threaded hole 101 in communication with a mounting hole. An internal hexagonal flat-end set screw 11 for fixing the bushing 2 in the mounting hole is screwedly installed in the threaded hole 101. The internal hexagonal flat-end set screw 11 is screwedly installed in the threaded hole 101. When the internal hexagonal flat-end set screw 11 is tightened, the end thereof abuts against the bushing 2, thereby firmly fixing the bushing 2 in the mounting hole of the mounting base 1 and preventing the bushing 2 from loosening or shifting during use.
[0035] Working principle:
[0036] When the support structure needs to be in working state, the operator pulls the handle 10, and the adjusting pad 6 slides in the U-shaped groove 102. The guide slope 602 of the adjusting pad 6 pushes the guide pin 3 to move upward in the bushing 2, the compression spring 7 is compressed, the guide pin 3 drives the support pad 5 to move away from the adjusting pad 6, and the support pad 5 reaches the working position and can be used to support the part to be detected.
[0037] When the support structure needs to be in non-working state, the operator pulls the handle 10, and the adjusting pad 6 slides reversely, and the guide pin 3 and the support pad 5 move toward the adjusting pad 6 under the elastic force of the compression spring 7.
[0038] The above description shows and describes several preferred embodiments of the utility model, but as before, it should be understood that the utility model is not limited to the form disclosed herein, and should not be considered as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept disclosed herein by the above teaching or related technical or knowledge. The modification and change made by the person skilled in the art without departing from the spirit and scope of the utility model should be within the protection scope of the claims attached to the utility model.
