DETAILED DESCRIPTION

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0013] like Figure 1 , Figure 2 As shown, the pressure-resistant hose comprises a left hose body 1 and a right hose body 2, both of which are provided with a fixing protrusion 3, and the fixing protrusion 3 and the corresponding hose body are provided with an integrally formed structure, and a positioning rod 4 is provided on the fixing protrusion 3 of the right hose body 2, and the positioning rod 4 can rotate on its fixing protrusion 3, and the two ends of the fixing protrusion 3 of the left hose body 1 are respectively provided with a positioning assembly 5 that fits with the positioning rod 4, and the positioning assembly 5 is composed of a positioning portion 6 and a reset spring 7, and a positioning rod 4 is provided at a position relative to the positioning assembly 5 and is provided with a positioning assembly 5 that fits with the positioning portion 6 The fixing protrusion 3 is provided with a mounting groove 9 for installing the positioning component 5, one end of the positioning portion 6 extends out of the mounting groove 9 and matches the positioning hole 8 of the positioning rod 4, the other end of the positioning portion 6 extends into the mounting groove 9, and the return spring 7 is sleeved on the positioning portion 6 at this end and arranged in the mounting groove 9, a clamping rod 10 is also provided at one end of the positioning rod 4, and a clamping groove 11 for clamping the clamping rod 10 is provided on the left hose main body 1, and the two hose main bodies are detachably fixedly connected to each other by the positioning portion 6 being matched with the positioning hole 8 and the clamping rod 10 being matched with the clamping groove 11.

[0014] To explain in further detail, when the two hose bodies are fixedly connected, first pull the pull rod 13 to retract one end of the positioning part 6 into the mounting groove 9. The reset spring 7 is in a compressed state and the positioning rod 4 is rotated to make the clamping rod 10 of the positioning rod 4 correspond to the clamping groove 11 of the left hose body 1. Then release the pull rod 13, the reset spring 7 rebounds, and one end of the positioning part 6 extends out of the mounting groove 9 and connects with the positioning hole 8 of the positioning rod 4. The two hose bodies can be fixedly connected. When the two hose bodies need to be separated, pull the pull rod 13 to retract one end of the positioning part 6 into the mounting groove 9. The positioning of the positioning rod 4 can be released, thereby canceling the fixed connection between the two hose bodies.

[0015] In further detail, the positioning portion 6 is further provided with a sliding portion 12 in the mounting groove 9, and the sliding portion 12 can slide back and forth in the mounting groove 9, and the other end of the positioning portion 6 extending out of the fixing protrusion 3 is further provided with a pulling rod 13 that can be pulled.

[0016] In further detail, the fixing protrusions 3 are arranged in pairs on the corresponding left hose body 1 and right hose body 2, and two positioning components 5 are arranged on each fixing protrusion 3 of the left hose body 1.
