[0002] In the process of bellows production and processing, in order to detect the quality of the produced bellows, it is necessary to test the pressure resistance of the bellows. The main way to test is to inject air into the bellows and observe the deformation of the bellows under a certain air pressure. Figure 4 This is a physical picture of the compression test of the bellows. However, the disadvantage of this testing equipment during use is that it can only test one type of bellows, and cannot test bellows with larger diameters, mainly because the capacity of the baffle is limited.

[0008] A plurality of threaded rods are rotatably arranged on the bottom plate, and the plurality of threaded rods surround the lower positioning groove. The cover plate has sliding holes at positions corresponding to the threaded rods, and the threaded rods slide through the sliding holes and are threadedly connected to the threaded sleeves.

[0009] The air nozzle pipe is arranged at the center of the cover plate and passes through the cover plate;

[0010] The retaining sleeve has one end extending into the lower positioning groove and the other end extending into the upper positioning groove, so that the bottom plate and the cover plate clamp the retaining sleeve.

[0011] Preferably, a rotating handle is fixedly connected to the outer side wall of the threaded sleeve.

[0012] Preferably, a fixing groove is provided at a position on the bottom plate corresponding to the threaded rod, and the threaded rod extends into the fixing groove and is fixedly connected to the inner wall of the fixing groove.

[0013] The beneficial effects of adopting the above technical solution are:

[0014] The present application can position retaining sleeves of different diameters by setting up different lower positioning grooves and upper positioning grooves, and can be suitable for the pressure resistance test of corrugated pipes of different sizes. Therefore, the present application can be adaptively adjusted according to the sizes of different corrugated pipes, thereby increasing the flexibility of use of the present application.

DETAILED DESCRIPTION

[0020] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-3 In the first embodiment, a bellows detection tool includes:

[0022] The bottom plate 10 has a plurality of lower positioning grooves 41 on its upper surface, and the plurality of lower positioning grooves 41 are arranged in a concentric circle.

[0023] The cover plate 20 has an upper positioning groove 42 at a position on the lower surface corresponding to the lower positioning groove 41;

[0024] A plurality of lower thread grooves 60 are disposed at positions on the inner side of each lower positioning groove 41 corresponding to the upper surface of the bottom plate 10, and a plurality of upper thread grooves 70 are disposed at positions on the inner side of each upper positioning groove 42 corresponding to the upper surface of the cover plate 20;

[0025] A plurality of threaded rods 30 are rotatably disposed on the bottom plate 10, and the plurality of threaded rods 30 surround the lower positioning groove 41. The cover plate 20 has a sliding hole 32 at a position corresponding to the threaded rod 30. The threaded rod 30 slides through the sliding hole 32 and is threadedly connected to the threaded sleeve 33.

[0026] The air nozzle tube 50 is disposed at the center of the cover plate 20 and penetrates the cover plate 20;

[0027] One end of the stopper sleeve 40 extends into the lower positioning groove 41 , and the other end extends into the upper positioning groove 42 , so that the bottom plate 10 and the cover plate 20 clamp the stopper sleeve 40 .

[0028] This embodiment is implemented as follows:

[0029] When the present application is in use, when a large-sized corrugated pipe is to be inspected, a large-diameter stopper sleeve 40 can be selected, and the two ends of the large-diameter stopper sleeve 40 can be inserted into the large-diameter lower positioning groove 41 and the upper positioning groove 70. By rotating the threaded sleeve 33, the cover plate 20 can apply pressure to the stopper sleeve 40, so that the stopper sleeve 40 can be clamped by the base plate 10 and the cover plate 20; the upper threaded groove 70 and the lower threaded groove 60 in the present application can be used to install the two ends of the corrugated pipe.

[0030] Compared with the prior art, the present application has the advantage that it can clamp retaining sleeves of different sizes, thereby adapting to corrugated pipes of different sizes.

[0031] See also Figure 1 A rotating handle 34 is fixedly connected to the outer wall of the threaded sleeve 33 .

[0032] The threaded sleeve 33 can be easily rotated by the provided rotating handle 34 , which eliminates the need to use a wrench to rotate the threaded sleeve 33 .

[0033] See also Figure 2 A fixing groove 31 is provided on the bottom plate 10 at a position corresponding to the threaded rod 30, and the threaded rod 30 extends into the fixing groove 31 and is fixedly connected to the inner wall of the fixing groove 31;

[0034] The threaded rod 30 is installed through the fixing groove 31 so that the end of the threaded rod 30 extends into the fixing groove 31 for greater stability.

[0035] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
