DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Example 1

[0026] In one embodiment, Figure 1-Figure 5 As shown, a PVC fiber reinforced hose comprises a PVC reinforced tube 1. A tightening mechanism is arranged inside the two connected PVC reinforced tubes 1. The tightening mechanism is used to connect the two PVC reinforced tubes 1 together. A leak-proof mechanism and a limiting mechanism are arranged at the connecting position of the two PVC reinforced tubes 1. The leak-proof mechanism is used to prevent water leakage due to aging of the water pipe. The limiting mechanism is used to limit the leak-proof mechanism to prevent the leak-proof mechanism from moving.

[0027] In one embodiment, Figure 3 As shown, the tightening mechanism includes a threaded pipe 4, wherein one PVC reinforced pipe 1 is provided with a threaded pipe 4, and another PVC reinforced pipe 1 is provided with a threaded sleeve corresponding to the threaded pipe 4, and the two PVC reinforced pipes 1 are tightened by rotating the threads to complete the connection of the two PVC reinforced pipes 1.

[0028] In one embodiment, Figure 4 As shown, the leakage prevention mechanism includes a first waterproof block 5, a second waterproof block 6, and a waterproof rubber ring 7. Waterproof grooves are provided in the first waterproof block 5 and the second waterproof block 6. A waterproof rubber ring is fixedly connected to the inner wall of the waterproof groove. The waterproof rubber ring 7 can protect the aging water pipe from water leakage. An installation structure and a disassembly structure are provided at the connection between the first waterproof block 5 and the second waterproof block 6.

[0029] In one embodiment, Figure 5 As shown, the installation structure includes a limiting groove 8, a limiting block 10, a snap hole 9, a snap groove 11, and a spring 3. The two raised parts of the first waterproof block 5 are both provided with a limiting groove 8. The two raised parts of the first waterproof block 5 are arcuate structures, which are convenient for squeezing the limiting block 10. The second waterproof block 6 is provided with a snap hole 9 corresponding to the raised part of the first waterproof block 5. The side wall of the second waterproof block 6 is provided with two snap grooves 11 corresponding to the limiting groove 8. The inner walls of the two snap grooves 11 are both slidably connected to the limiting block 10. The part of the limiting block 10 located in the snap hole 9 is an arc surface, which is convenient for matching with the raised part. The spring 3 is fixedly connected between the limiting block 10 and the inner wall of the snap groove 11. Insert the raised part of the first waterproof block 5 into the buckle hole 9 of the second waterproof block 6. At this time, the spring 3 cooperates with the limit block 10. When the limit groove 8 slides to the position of the buckle groove 11, the limit block 10 is pushed into the limit groove 8 under the pressure of the spring 3 to limit the first waterproof block 5, completing the installation of the first waterproof block 5 and the second waterproof block 6. The installation is quick and convenient.

[0030] In one embodiment, Figure 5 As shown, the disassembly structure includes a rotating shaft 12, a clamping block 13, and a pull ring 14. A clamping block groove is provided in the second waterproof block 6, and the clamping block 13 is slidably connected to the inner side wall of the clamping block groove. The side wall of the limit block 10 is rotatably connected to the rotating shaft 12 through a bearing. The rotating shaft 12 passes through the second waterproof block 6 and extends into the clamping block groove. The end of the rotating shaft 12 away from the limit block 10 is fixedly connected to the side wall of the clamping block 13, and the side wall of the clamping block 13 away from the rotating shaft 12 is fixedly connected to the pull ring 14. When disassembly is required, the clamping block 13 is pulled out of the clamping block groove through the pull rings 14 on both sides, and rotated 90 degrees to be clamped outside the clamping block groove. The clamping block drives the rotating shaft 12 to move, and the rotating shaft 12 drives the limit block 10 to move. The limit block 10 is first pulled out of the limit groove 8 and then the first waterproof block 5 is taken out, so that the disassembly of the first waterproof block 5 and the second waterproof block 6 can be completed, and the disassembly is quick and convenient.

[0031] Example 2

[0032] In one embodiment, Figure 5 As shown, the pull ring 14 is engraved with anti-skid lines to increase the friction between the pull ring and the palm to prevent the hand from slipping.

[0033] In one embodiment, Figure 1 As shown, the limiting mechanism includes a limiting ring 2, and the two connected PVC reinforced pipes are fixedly connected with the limiting ring 2. The leak-proof mechanism is limited to prevent the leak-proof mechanism from moving.

[0034] In one embodiment, Figure 4 and Figure 5As shown, the portion of the limit block 10 located in the buckle hole 9 and the raised portion of the first waterproof block 5 are both arc surfaces, so that the raised portion cooperates with the limit block 10 and squeezes the limit block 10 into the buckle groove 11.

[0035] The above embodiment discloses a PVC fiber reinforced hose. First, two PVC reinforced pipes 1 are tightened through the threaded pipe 4 and the corresponding threaded sleeves, and then the convex part of the first waterproof block 5 is inserted into the buckle hole 9 of the second waterproof block 6 in the two limiting rings 2. At this time, the spring 3 cooperates with the limiting block 10. When the limiting groove 8 slides to the position of the buckle groove 11, the limiting block 10 is pushed into the limiting groove 8 under the pressure of the spring 3 to limit the first waterproof block 5, completing the installation of the first waterproof block 5 and the second waterproof block 6. When it needs to be disassembled, the Through the pull rings 14 on both sides, the card block 13 is pulled out of the card block groove and rotated ninety degrees to be stuck outside the card block groove. The card block drives the rotating shaft 12 to move, and the rotating shaft 12 drives the limit block 10 to move. The limit block 10 is pulled out of the limit groove 8 and then the first waterproof block 5 is taken out, and the disassembly of the first waterproof block 5 and the second waterproof block 6 can be completed. The installation and disassembly operations are simple and convenient, and do not require reinforcement by various bolts, which saves installation and disassembly time. In addition, the waterproof rubber ring 7 between the first waterproof block 5 and the second waterproof block 6 can protect the aging water pipe from leakage.

[0036] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
