[0042] For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0043] Please refer to Figure 1 A clamping structure for a PPR pipe according to a preferred embodiment of the utility model includes a first pipe 100 , a second pipe 200 and an adjusting ring 220 .

[0044] A first clamping member 110 is fixedly disposed on one end of the first tube 100 , and a clamping groove 120 is disposed on the first clamping member 110 . The clamping groove 120 has an unlocking section 121 and a locking section 122 that are connected to each other. The unlocking section 121 extends to an edge of the first clamping member 110 that is away from the first tube 100 .

[0045] The second tube 200 is coaxially arranged with the first tube 100. A second clamping member 210 is movably arranged on the end of the second tube 200 opposite to the first clamping member 110. The movement path of the second clamping member 210 has an unlocking position and a locking position. When the second clamping member 210 is in the unlocking position, the second clamping member 210 is in the unlocking section 121. When the second clamping member 210 is in the locking position, the second clamping member 210 is in the locking section 122, and the second clamping member 210 is in a clamping state with the clamping groove 120.

[0046] The adjusting ring 220 is rotatably arranged on the second tube 200, and the adjusting ring 220 is connected to the second clamping member 210. The adjusting ring 220 drives the second clamping member 210 to move between the unlocking position and the locking position, so that the second clamping member 210 can enter the locking section 122 from the unlocking section 121 and enter the unlocking section 121 from the locking section 122.

[0047] The first tube 100 and the second tube 200 are two pipes that are intended to be connected. To facilitate connecting multiple pipes together, a first clamping piece 110 and a second clamping piece 210 may be provided at both ends of the same pipe, respectively, so that multiple pipes can be connected end to end.

[0048] Please refer to Figure 2 and Figure 3 When the second clamping member 210 is in the locking position and the second clamping member 210 is located in the locking section 122 , the first tube 100 and the second tube 200 are clamped together.

[0049] During docking, the staff rotates the adjustment ring 220 to drive the second clamping member 210 to move. The second clamping member 210 first moves from the unlocking position to the locking position. During this process, the second clamping member 210 moves in the unlocking section 121 until it enters the locking section 122, and the second clamping member 210 also moves to the locking position.

[0050] When the second clamping member 210 is in the unlocking position and the second clamping member 210 is located in the unlocking section 121 , the clamping connection between the first tube 100 and the second tube 200 is released.

[0051] When separating the first tube 100 and the second tube 200, the staff rotates the adjusting ring 220, thereby driving the second clamping member 210 to move. The second clamping member 210 first moves from the moving position to the unlocking position. During this process, the second clamping member 210 moves in the locking section 122 until it enters the unlocking section 121, and the second clamping member 210 also moves to the unlocking position.

[0052] The clamping structure for the PPR pipe of this embodiment can realize the rapid docking of the first pipe 100 and the second pipe 200 through such a structure, and the disassembly and assembly efficiency is high, and the installation efficiency is also improved accordingly.

[0053] In this embodiment, the first clamping member 110 is in sheet shape and is provided in plurality, and the plurality of first clamping members 110 are uniformly surrounded on the outer wall of the first tube 100. The number and position of the second clamping members 210 match those of the first clamping members 110.

[0054] In some embodiments, please refer to Figure 4 The clamping structure for the PPR pipe also includes an elastic member 230, which is sleeved on the second pipe 200, and the adjusting ring 220 is sleeved on the second pipe 200 through the elastic member 230; when the external force drives the adjusting ring 220 to drive the second clamping member 210 to move to the unlocking position, the elastic member 230 accumulates elastic force, and when the external force is removed, the elastic member 230 drives the adjusting ring 220 to reset, and the adjusting ring 220 drives the second clamping member 210 to move to the locking position.

[0055] In this embodiment, the elastic member 230 is a spiral spring.

[0056] When an external force is applied to the adjusting ring 220, the elastic force of the elastic member 230 needs to be overcome so that the second clamping member 210 moves from the locking position to the unlocking position. When the external force is removed, the elastic force of the elastic member 230 resets the second clamping member 210, and the second clamping member 210 remains in the locking position. In other words, when there is no external force, the first tube 100 and the second tube 200 can maintain a connected state. When the first tube 100 and the second tube 200 are connected, an external force needs to be applied to overcome the elastic force of the elastic member 230 so that the second clamping member 210 can first align with the unlocking section 121 and enter the unlocking section 121. After the second clamping member 210 enters the locking section 122, the external force is removed, and the elastic force of the elastic member 230 keeps the second clamping member 210 in the state of the locking section 122, completing the clamping of the first tube 100 and the second tube 200. When separating the first tube 100 and the second tube 200 in the clamped state, it is also necessary to first apply an external force to make the second clamping member 210 leave the locking section 122, and then after leaving the unlocking section 121, the external force can be removed. At this time, the first tube 100 and the second tube 200 have been separated.

[0057] In some embodiments, the clamping structure for the PPR pipe also includes a first ring 130 and a second ring 240, the first ring 130 is fixedly mounted on one end of the first pipe 100, and the first clamping member 110 is arranged on the first ring 130; the second ring 240 is fixedly mounted on one end of the second pipe 200, and the second clamping member 210 and the adjustment ring 220 are both movably arranged on the second ring 240.

[0058] By providing the first sleeve ring 130 , the first clamping member 110 can be provided on the first tube 100 , and by providing the second sleeve ring 240 , the second clamping member 210 and the adjusting ring 220 can be provided on the second tube 200 .

[0059] In some embodiments, a surface of the second ring 240 further forms an avoidance groove 241 , which is located on the side of the adjustment ring 220 facing the first ring 130 , and at least a portion of the second clip 210 is located in the avoidance groove 241 , which matches the first clip 110 .

[0060] In this embodiment, in order to form the unlocking section 121 , after the first clamping member 110 is clamped, a portion of the first clamping member 110 will exist on both sides of the second clamping member 210 .

[0061] The avoidance portion is provided to avoid the first clamping member 110 , thereby preventing the first clamping member 110 from interfering with the structures on the second ring 240 , thereby affecting the cooperation between the first clamping member 110 and the second clamping member 210 .

[0062] In some embodiments, a sliding groove 242 is provided on the groove wall of the avoidance groove 241 , one end of the second clamping member 210 is fixedly connected to the adjustment ring 220 , and the other end of the second clamping member 210 is slidably connected to the sliding groove 242 .

[0063] When the adjusting ring 220 rotates, the second clamping member 210 slides in the sliding groove 242 , and the sliding groove 242 of the second clamping member 210 limits the sliding path of the second clamping member 210 .

[0064] In some embodiments, please refer to Figure 5 and Figure 6 A guide rail 243 and a slider 244 are provided in the slide groove 242 . The slider 244 can be slidably connected to the guide rail 243 , and the second clamping member 210 is fixedly connected to the slider 244 .

[0065] When the adjusting ring 220 rotates, the second clamping member 210 and the slider 244 move, and the slider 244 slides on the guide rail 243. The arrangement of the guide rail 243 and the slider 244 can make the movement of the second clamping member 210 more stable.

[0066] In some embodiments, the extending direction of the unlocking section 121 is parallel to the docking direction of the first tube 100 and the second tube 200 .

[0067] With such a structure, during docking, the second clamping member 210 can enter the unlocking section 121 and move in the unlocking section 121 until entering the locking section 122, which is convenient for the operator to operate.

[0068] In some embodiments, the extending direction of the locking segment 122 matches the moving direction of the second clamping member 210 .

[0069] In this way, when the adjusting ring 220 rotates, the second clamping member 210 can move directly in the locking section 122. In other embodiments, the locking section 122 can also be arranged to be slightly inclined.

[0070] In some embodiments, a sealing gasket 140 is disposed on the end surface of the first ring 130 facing the second ring 240 .

[0071] After the first tube 100 and the second tube 200 are connected, the sealing gasket 140 can seal the gap between the first tube 100 and the second tube 200 to prevent water leakage at the connection between the first tube 100 and the second tube 200.

[0072] In some embodiments, the second clamping member 210 includes a connecting portion 211 and a matching portion 212 connected to each other, the connecting portion 211 and the matching portion 212 together form a right angle, the connecting portion 211 is also connected to the adjustment ring 220, and the matching portion 212 is movably arranged on the second tube 200, and the matching portion 212 can move within the unlocking section 121 and the locking section 122.

[0073] The shape of the second clamping member 210 can, on the one hand, help it connect the adjusting ring 220 and the slider 244 , and on the other hand, facilitate it to enter the unlocking section 121 and move within the unlocking section 121 and the locking section 122 .

[0074] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
