[0036] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0037] Example 1: An air-conditioning compressor cylinder body detection fixture, see Figures 1 to 4 , comprising a base 1, an adjustment structure 2 and a positioning rod 4;

[0038] The four corners of the base 1 are respectively positioned on the operating table by bolts; the three adjustment structures 2 are respectively arranged on the three sides of the top side of the base 1; the bottom end of the positioning rod 4 is arranged on the sliding part of the adjustment structure 2 through the connecting structure 3;

[0039] The adjusting structure 2 includes a slider 201, a threaded rod 202 and a handle 203;

[0040] The slider 201 is slidably disposed in the slide groove A101 opened on the top side of the base 1; the threaded rod 202 is threadedly penetrated on the slider 201; wherein, the inner end of the threaded rod 202 is rotatably connected to the inner bottom wall of the slide groove A101; the rotating handle 203 is fixedly disposed at the outer end of the threaded rod 202.

[0041] The utility model has the advantage of being highly applicable, and solves the problem that there are differences in the sizes of compressor cylinders of the same category, the columns on the same jig cannot be adjusted, and the jig is not fully applicable to compressor cylinders of the same category.

[0042] Specifically, two inner side walls of the slide groove A101 are respectively provided with slide grooves B102 , and two sides of the slider 201 are respectively fixed with limit blocks 204 , and the limit blocks 204 are slidably matched with the slide grooves B102 .

[0043] The utility model has the advantage of limiting the moving slider 201 by setting the limiting block 204 and the slide groove B102, so that the slider 201 can move stably in the slide groove A101.

[0044] Furthermore, the contact side of the limit block 204 adopts an arc-shaped structure design, and the limit block 204 is adapted to the slide groove B102; the sliding resistance between the contact side of the arc-shaped limit block 204 and the slide groove B102 is smaller.

[0045] Furthermore, the connection structure 3 includes an insert block 301, a connection sleeve 302 and an abutment spring sheet 303;

[0046] The plug block 301 is fixed at the bottom end of the positioning rod 4; the connecting sleeve 302 is fixed at the top side of the slider 201; wherein the plug block 301 and the connecting sleeve 302 are plugged together; four abutting spring sheets 303 are arranged in a circular array on the outer wall of the plug block 301; wherein the four abutting spring sheets 303 are respectively plugged together with four slots 304 opened in a circular array on the inner wall of the connecting sleeve 302.

[0047] The utility model has the advantages that the positioning rod 4 can be quickly installed or disassembled with the slider 201 by arranging the insert block 301, the slot 304, the connecting sleeve 302 and the abutting spring piece 303, and the positioning rod 4 that is excessively worn can be quickly replaced.

[0048] It is worth noting that the abutting spring piece 303 adopts an arc-shaped structural design, and the arched end of the abutting spring piece 303 is adapted to the slot 304; the arc-shaped abutting spring piece 303 is easier to bend when squeezed, and is also easier to rebound after being squeezed.

[0049] It is worth noting that a gap is left between the outer wall of the insert block 301 and the inner wall of the connecting sleeve 302, providing enough space for the abutting spring sheet 303 to be squeezed and bent.

[0050] Working principle: Using the device of the utility model, the position of the positioning rod 4 is adjusted according to the position of the mounting holes on the compressor cylinder bodies of the same category and different sizes. The handle 203 is turned, and the threaded rod 202 rotates relative to the base 1. The slider 201 slides in the slide groove A101 along the threaded rod 202, and the limit block 204 slides in the slide groove B102 to limit the slider 201 until the positioning rod 4 is adjusted to the position corresponding to the mounting hole on the corresponding compressor cylinder body, and the mounting hole on the compressor cylinder body is mounted corresponding to the positioning rod 4, and the compressor cylinder body is positioned on the base 1.

[0051] When replacing the excessively worn positioning rod 4, directly pull the positioning rod 4 upwards, and the arc-shaped abutting spring piece 303 will be squeezed out from the slot 304, and the new positioning rod 4 will be installed on the slider 201, and the plug block 301 will be inserted into the connecting sleeve 302. The arc-shaped abutting spring piece 303 is inserted into the connecting sleeve 302 and is squeezed and bent by the inner wall of the connecting sleeve 302. Wait until the plug block 301 is completely inserted into the connecting sleeve 302. If the arched end of the abutting spring piece 303 is not engaged with the slot 304, rotate the positioning rod 4, and the bent abutting spring piece 303 will rotate accordingly until the arched end of the abutting spring piece 303 corresponds to the slot 304, and the abutting spring piece 303 rebounds and engages with the slot 304 to fix the new positioning rod 4.

[0052] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
