The other end of the support column is fixed to the outer side surface of the inner sleeve tube, and the inner sleeve tube is fitted over the rear connecting end.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The two sets of front explosion-proof mesh covers fixed on the upper and lower sides of the front pipe section and the front connecting end of this utility model can not only strengthen the reinforcement and fixation of the front part of the hose joint, but also provide explosion protection for the installation of the front connecting end and the front connecting pipe end, making it more stable and firm; at the same time, the fastening bolts are convenient to install or disassemble, making it more convenient and practical.

[0013] 2. The addition of a reinforcing hoop in this utility model helps to strengthen the fixation of the middle part of the inner joint, enhances the explosion-proof strength of the medium being transported inside the middle part of the inner joint, and makes it more pressure-resistant and durable.

[0014] 3.
