A chute 5 is formed at the bottom of the opening 4, a locking hole 6 is formed on one side of the chute 5, and an elastic locking rod 8 is provided on one side of the slider 7.

[0034] By adopting the above technical solution, the device can quickly fix the pneumatic pipe joint body 2 and the mounting base 1 through the locking mechanism, thus greatly facilitating the installation and disassembly of the pneumatic pipe joint body 2 by the operator, and further greatly improving the maintenance and replacement efficiency of the pneumatic pipe joint body 2 by the maintenance personnel.

[0035] In the embodiment of the present application, as Figure 1 shown, the sealing mechanism includes a sealing airbag 9 provided on the inner wall of the sealing cylinder 3. The other side of the sealing airbag 9 is fixedly connected with an elastic ring 10. A nozzle 11 is provided on the outer surface of the sealing cylinder 3, and the other end of the nozzle 11 is fixedly connected with the sealing airbag 9.

[0036] By adopting the above technical solution, the device can seal the connecting pipe through the sealing mechanism, thereby avoiding air leakage of the pneumatic pipe joint body 2, and further greatly improving the connection stability and sealing performance of the device.

[0037] In the embodiment of the present application, as Figure 4 shown, the elastic locking rod 8 includes a locking outer rod 801. A locking spring 802 is fixedly connected to the inner wall of the locking outer rod 801. A locking inner rod 803 is fixedly connected to one side of the locking spring 802, and the other end of the locking inner rod 803 extends to the outside of the mounting base 1 through the locking hole 6.

[0038] By adopting the above technical solution, by utilizing the elastic action of the locking spring 802, the locking effect of the device is better.
