[0024] For examples, please refer to Figure 1-4 This utility model provides a technical solution:

[0025] A high-pressure resin hose assembly that is easy to connect includes a resin hose body 1. A connecting component 2 is provided at one end of the resin hose body 1. A mating plug 3 is provided on the side of the connecting component 2 away from the resin hose body 1. The connecting component 2 includes a connector 201 fixedly connected to one end of the resin hose body 1. Anti-backflow plates 202 are rotatably connected to both the upper and lower sides of the inner cavity of the connector 201. Return springs 203 are fixedly connected to the ends of the upper and lower sides of the inner cavity of the connector 201 near the resin hose body 1. Installation cavities 204 are formed in the inner walls of both the upper and lower sides of the connector 201. Each of the two mounting cavities 204 has a movable plate 205 inside. Both ends of the movable plates 205 are connected by vertical rods 206. The outer walls of the two vertical rods 206 are fitted with telescopic springs 207. One end of each of the four telescopic springs 207 is fixedly connected to the inner wall of the two mounting cavities 204, and the other end of each of the four telescopic springs 207 is fixedly connected to the surface of the two movable plates 205. A connecting rod 208 is fixedly connected to the middle of the opposite side of each of the two movable plates 205. The ends of the two connecting rods 208 away from the movable plates 205 extend into the inner cavity of the connector 201.

[0026] like Figure 2 , Figure 3 , Figure 4 As shown, the other ends of the two return springs 203 are fixedly connected to the surfaces of the two anti-backflow plates 202 that are far apart from each other. The opposite ends of the two anti-backflow plates 202 are tightly pressed against each other. The two ends of the four vertical rods 206 are fixedly connected to the inner walls of the upper and lower sides of the two mounting cavities 204. The surfaces of the four vertical rods 206 are slidably connected to the inner walls of the two sides of the two moving plates 205. The ends of the two connecting rods 208 that are close to each other are inclined and symmetrical. The sides of the two moving plates 205 that are far away from the connecting rods 208 are fixedly connected to pull rods 209. The ends of the two pull rods 209 that are far away from the moving plates 205 extend to the outside of the two mounting cavities 204. One end of the docking plug 3 is inserted into the inner cavity of the connector 201. The upper and lower sides of the docking plug 3 are symmetrically provided with connecting slots 4. The two connecting slots 4 are adapted to the shapes of the two connecting rods 208. The two connecting rods 208 are respectively locked into the inner cavities of the two connecting slots 4.

[0027] like Figure 1 , Figure 2 As shown, the resin hose body 1 includes a hose inner core 101, and a reinforcing braided layer 102 is provided on the outer wall of the hose inner core 101. The reinforcing braided layer 102 is made of aluminum wire braiding, and a textured outer tube 103 is provided on the outer wall of the reinforcing braided layer 102. The outer wall of the textured outer tube 103 is textured.

[0028] The working process of this utility model is as follows: During use, the connector 201 is inserted into the outside of the docking plug 3. The docking plug 3 presses against the connecting rods 208 on both sides, causing them to move. The connector 201 then continues to move closer to the docking plug 3. When the connecting rods 208 reach the connecting slot 4, they are pushed and engaged inside the connecting slot 4 by the moving plate 205 under the elastic force of the telescopic spring 207, thus completing the connection between the docking plug 3 and the resin hose body 1. One end of the docking plug 3 connects to the two anti-backflow plates 2. When the 02 is in an open state and needs to be separated, the pull rod 209 is used to pull the two moving plates 205 to move, and the two connecting rods 208 leave the inside of the connecting slot 4, so that the resin hose body 1 and the docking plug 3 can be separated. At the same time, under the action of the return spring 203, the two anti-backflow plates 202 are in a closed state to prevent the medium remaining on the inner wall of the resin hose body 1 from flowing out. The reinforcing braided layer 102 and the textured outer tube 103 provided on the outside of the resin hose body 1 can enhance the strength and tensile strength of the resin hose body 1.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
