Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 A high-pressure quick-connect coupling includes an upper connecting pipe 100 and a lower connecting pipe 200. A first fixing plate 110 is fixedly connected to the inner wall of the upper connecting pipe 100. A first spring 120 is fixedly connected to the lower side of the first fixing plate 110. A stop block 130 is fixedly connected to the lower side of the first spring 120. A discharge pipe 140 is fixedly connected to the lower side of the first fixing plate 110. A first rubber layer 141 is fixedly connected to the upper side of the discharge pipe 140. By setting the first rubber layer 141, the tightness of the contact between the stop block 130 and the discharge pipe 140 is improved, so that the upper... When the connecting pipe 100 is disconnected from the lower connecting pipe 200, and the material pressure inside the upper connecting pipe 100 is too high, causing the stop block 130 to be squeezed, the stop block 130 is tightly connected to the discharge pipe 140, improving the ease of use of this device. This allows the connection and disconnection of the upper connecting pipe 100 and the lower connecting pipe 200 to be completed without additional operation. Discharge holes are evenly distributed on the outer side of the discharge pipe 140. A second fixing plate 210 is fixedly connected to the inner wall of the lower connecting pipe 200, and a second rubber layer 211 is fixedly connected to the upper side of the second fixing plate 210. By setting... The second rubber layer 211 improves the tightness of contact between the upper connecting pipe 100 and the lower connecting pipe 200, enhancing the stability of the device. A feed pipe 220 is fixedly connected to the inner wall of the second fixing plate 210. As the lower connecting pipe 200 moves upward, it can drive the second fixing plate 210 and the feed pipe 220 upward. During this upward movement, the feed pipe 220 presses against the stop block 130 and inserts into the interior of the upper connecting pipe 100. The feed pipe 220 is fitted over the outside of the discharge pipe 140. The upper connecting pipe 100 is inserted into the interior of the lower connecting pipe 200, and then... The limit device 300 completes the connection between the upper connecting pipe 100 and the lower connecting pipe 200. By setting the first spring 120, the first fixing plate 110, the stop block 130, the discharge pipe 140, the first rubber layer 141, the second fixing plate 210, and the second rubber layer 211 to cooperate with the lower connecting pipe 200, the upper connecting pipe 100 and the lower connecting pipe 200 can be connected to seal the raw material, so that the upper connecting pipe 100 and the lower connecting pipe 200 can be quickly connected without leakage. At the same time, it allows the staff to quickly change different workpieces as needed.

[0022] A limiting device 300 is provided on the outer side of the upper connecting pipe 100 and the lower connecting pipe 200. The limiting device 300 includes a moving pipe 310, and a third rubber layer 311 is fixedly connected to the inner wall of the moving pipe 310. By setting the third rubber layer 311, the moving pipe 310 and the lower connecting pipe 200 are in closer contact, which makes the material more stable when the upper connecting pipe 100 and the lower connecting pipe 200 are connected. Four sets of second springs 320 are fixedly connected to the lower side of the moving pipe 310. A locking block 330 is fixedly connected to the side of the second spring 320 away from the moving pipe 310. Grooves are opened on the lower sides of the moving pipe 310 and the second springs 320. Spring 320 and locking block 330 are both located inside the groove of moving tube 310. Moving tube 310 is located outside the upper connecting tube 100. A locking groove matching locking block 330 is provided on the outer side of the lower connecting tube 200. During use, moving tube 310 is fitted onto the outer side of lower connecting tube 200. Then, lower connecting tube 200 presses against locking block 330, causing locking block 330 to be forced into moving tube 310. Moving tube 310 then continues to move downwards until it reaches a predetermined position. Subsequently, locking block 330 moves and presses against the second spring 320, causing the elastic force generated by the deformation of the second spring 320 to drive locking block 330 back to its original position and lock into lower connecting tube 200. The slot completes the connection between the upper connecting pipe 100 and the lower connecting pipe 200. The limiting device 300 allows for quick connection between the upper connecting pipe 100 and the lower connecting pipe 200, improving the efficiency and speed of the device's use, as well as its convenience and practicality. Two sets of limiting blocks 400 are fixedly connected to the outer side of the upper connecting pipe 100. A limiting groove matching the limiting block 400 is opened on the upper side of the moving pipe 310. The limiting block 400 limits the position of the moving pipe 310. When needed, the moving pipe 310 is moved to the lower side of the limiting block 400, and rotated to pass through the limiting block. The limiting block 400 limits the movement tube 310, improving the stability of the device. When the movement tube 310 needs to be disassembled, it is rotated, and then the limiting block 400 is located in the limiting groove. The limiting block 400 is fixedly connected to the inside of the limiting block 400. Two sets of first magnetic blocks 312 and two sets of third magnetic blocks 313 are fixedly connected to the upper side of the movement tube 310. By setting the first magnetic blocks 312, third magnetic blocks 313 and second magnetic blocks 410, the movement tube 310 is effectively limited in disassembly or fixing mode, improving the stability and safety of the device.
