Detailed Implementation

[0023] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 The present invention will be further described in detail below:

[0024] This utility model discloses a quick-release interchangeable device for high-efficiency measurement of automotive inspection tools, such as... Figure 1 , Figure 2 As shown, this utility model discloses a quick-release interchangeable device for high-efficiency measurement of automotive inspection tools, comprising a first mounting base 1 installed on an inspection platform and a second mounting base 2 for mounting a dial indicator. A fixing hole 11 is provided through the top of the first mounting base 1, and a fixing protrusion 12 that mates with the fixing hole 11 is welded to the bottom of the second mounting base 2. A fixing assembly for clamping the fixing protrusion 12 is provided inside the first mounting base 1. In this embodiment, the specific shapes and structures of the first mounting base 1 and the second mounting base 2 are as follows: Figure 1 , Figure 2As shown. The top of the first mounting base 1 has four threaded holes, which allow it to be fixed to the top of the testing platform. The top of the second mounting base 2 has four countersunk threaded holes, which, along with bolts, secure the detachable block with the dial indicator to the second mounting base 2. In use, the fixing protrusion 12 at the bottom of the second mounting base 2 with the dial indicator installed is inserted into the fixing hole 11 at the top of the first mounting base 1. The fixing assembly is then used to secure the second mounting base 2 for the first test. After the test, the fixing assembly is used to remove the second mounting base 2 and the dial indicator. The second mounting base 2, equipped with another angle dial indicator, is then fixed to the top of the first mounting base 1 for another test.

[0025] like Figure 3 , Figure 4 As shown, the fixing assembly includes a ring gear ring 31, a rotating block 33, a gear 32, and a handle 34. The first mounting base 1 has an internal accommodating chamber 35. A sliding groove 36 is formed on the outer wall of the first mounting base 1, communicating with the accommodating chamber 35. The ring gear ring 31 is disposed inside the accommodating chamber 35. A handle 34 is integrally formed on the outer wall of the ring gear ring 31, passing through and sliding within the sliding groove 36. The gear 32 is rotatably connected inside the accommodating chamber 35. A rotating block 33 is integrally formed on the top of the gear 32, meshing with the ring gear ring 31. A locking component for locking the handle 34 is disposed inside the handle 34. In this embodiment, the specific shapes and positions of the ring gear ring 31, rotating block 33, gear 32, and handle 34 are as follows: Figure 3 , Figure 4 As shown, the receiving chamber 35 is circular in shape, and its inner diameter is slightly larger than that of the ring gear ring 31. The ring gear ring 31 is an annular ring with teeth on the inner ring and a smooth outer ring. By rotating the handle 34, the ring gear ring 31 can be rotated within the receiving chamber 35. The rotating block 33 is integrally formed with the gear 32, and the rotating block 33 rotates around the axis of the gear 32. Preferably, the side wall of the fixing protrusion 12 is chamfered, and the side wall of the rotating block 33 that contacts the fixing protrusion 12 is rounded. By setting up the ring gear ring 31, the rotating block 33, the gear 32, and the handle 34, the clamping and loosening of the fixing protrusion 12 can be easily achieved by rotating the handle 34. The operation is simple and convenient, greatly shortening the measurement preparation time and improving the overall measurement efficiency. By setting up a locking component, the stability of the handle 34 in the locked state is ensured, preventing the dial indicator from loosening or falling off due to misoperation. When in use, rotating the handle 34 causes the ring gear ring 31 to rotate within the accommodating chamber 35, thereby causing the gear 32 meshing with it to rotate. At this time, the rotating block 33 will clamp the fixing protrusion 12 from different directions.

[0026] like Figure 2 , Figure 5 As shown, the locking assembly includes a locking pin 41, a spring 42, and several locking prisms 43. The inner wall of the slide groove 36 is provided with several locking prisms 43. The handle 34 has an internal receiving groove 44. One end of the spring 42 is fixedly connected to the inner wall of the receiving groove 44, and the other end of the spring 42 is fixedly connected to the locking pin 41. The locking pin 41 is L-shaped. A sliding groove 45 is formed at the top of the receiving groove 44, and the top of the locking pin 41 passes through the sliding groove 45 and extends beyond it. In this embodiment, by providing the locking pin 41, spring 42, and locking prisms 43, the end of the locking pin 41 can be engaged with the surface of the locking prism 43, thereby fixing the angle of the handle 34. Preferably, the cross-section of the locking prism 43 is triangular, and the end of the locking pin 41 that contacts the locking prism 43 forms a driving inclined surface 411. The cross-section of the driving inclined surface 411 at the end of the locking pin 41 is a triangle that matches the locking prism 43. When locked, rotating the handle 34 causes the locking pin 41 to slide on the surface of the locking prism 43 and compress the spring 42. When the locking pin 41 reaches the next locking prism 43, it will pop out under the action of the spring 42 and lock onto the next locking prism 43, allowing the handle 34 to be adjusted step by step, thereby fixing the rotation angle of the rotating block 33 step by step. When unlocking, driving the locking pin 41 along the sliding groove 45 into the receiving groove 44 allows the handle 34 to be rotated to release the lock on the fixed protrusion 12.

[0027] like Figure 1 , Figure 2 As shown, the top of the first mounting base 1 is provided with a positioning groove 13, and the bottom of the second mounting base 2 is integrally formed with a positioning protrusion 14 that cooperates with the positioning groove 13. In this embodiment, by setting the positioning groove 13 and the positioning protrusion 14, the positioning accuracy of the second mounting base 2 is enhanced and the installation efficiency is improved.

[0028] The implementation principle of this utility model embodiment is as follows:

[0029] First, insert the fixing protrusion 12 at the bottom of the second mounting base 2 with the dial indicator installed into the fixing hole 11 at the top of the first mounting base 1. Rotate the handle 34 to make the rotating block 33 clamp the fixing protrusion 12 from different directions to complete the fixing of the second mounting base 2. Use the dial indicator to perform the first test.

[0030] Secondly, after the first test is completed, the finger drives the locking pin 41 to enter the receiving groove 44 along the sliding groove 45 and rotates the handle 34 in the opposite direction, so that the rotating block 33 releases the lock on the fixed protrusion 12, thereby removing the second mounting base 2 and the dial indicator.

[0031] Finally, insert the fixing protrusion 12 at the bottom of the second mounting base 2, which is equipped with another angle dial indicator, into the fixing hole 11 at the top of the first mounting base 1, turn the handle 34 to fix the second mounting base 2, and use the dial indicator to perform a second test.
