Technical Field

[0001] This utility model relates to the field of concrete pipe technology, specifically a reinforced concrete spigot and socket pipe. Background Technology

[0002] Concrete pipes are pipes made of concrete or reinforced concrete, used to transport fluids such as water, oil, and gas. They can be divided into four types: plain concrete pipes, ordinary reinforced concrete pipes, self-stressed reinforced concrete pipes, and prestressed concrete pipes.

[0003] Currently available reinforced concrete spigot and socket pipes require cement for sealing during use, and leakage can occur over long periods of use. Therefore, there is an urgent need for a new type of reinforced concrete spigot and socket pipe to improve these problems. Utility Model Content

[0012] By adopting the above technical solution, the fixing ring is fixedly connected to the outside of the pipe body, which facilitates the splicing of the pipe body.

[0013] The present invention is further configured such that: the positioning shaft is fixedly connected to one side of the sealing plate, the positioning hole is adapted to the positioning shaft, and the fixing bolt is engaged inside the through hole.

[0014] By adopting the above technical solution, the fixing bolts are snapped into the inside of the through hole, which serves to fix the sealing plate.

[0015] In summary, the beneficial technical effects of this utility model are as follows:

[0016] This reinforced concrete spigot and socket pipe uses screw holes and fixing screws to connect the support ring and support frame.

Example

[0025] Reference Figures 1 to 4 This utility model discloses a reinforced concrete socket pipe, comprising a pipe body 1, a support frame 2 inside the pipe body 1, screw holes 3 inside the support frame 2, fixing screws 4 inside the screw holes 3, and a support ring 5 outside the fixing screws 4. Inclined surfaces A6 and B7 are formed at both ends of the pipe body 1. A sealing groove 8 is formed on the surface of the inclined surface A6, and a sealing ring 9 is formed inside the sealing groove 8. A fixing ring 10 is formed on the outside of the pipe body 1, and a sealing plate 11 is formed on the outside of the fixing ring 10. A positioning hole 12 and a through hole 13 are formed inside the sealing plate 11. A positioning shaft 14 is formed inside the positioning hole 12, and a fixing bolt 15 is formed inside the through hole 13. In this embodiment, the support frame 2 serves to increase the strength of the pipe body 1, the screw holes 3 facilitate the installation of the fixing screws 3, and the fixing screws 3 connect the support ring 5 and the support frame 12.

[0026] Reference Figure 2 The support ring 5 and the support frame 2 are both snapped into the inside of the pipe body 1. The fixing screw 4 is matched with the screw hole 3. The support ring 5 is snapped into both ends of the support frame 2. In this embodiment, the support ring 5 plays the role of restricting the support frame 2.

[0027] Reference Figure 2 , Figure 3 and Figure 4 A sealing groove 8 is provided on the surface of the inclined surface B7. The inclined surface A6 is adapted to the inclined surface B7. The sealing ring 9 is snapped into the inside of the sealing groove 8. In this embodiment, both the inclined surface A6 and the inclined surface B7 play the role of increasing the sealing performance. The sealing groove 8 plays the role of facilitating the installation of the sealing ring 9. The sealing ring 9 plays the role of preventing water leakage.

[0028] Reference Figure 1The fixing ring 10 is fixedly connected to the outside of the pipe body 1, and the sealing plate 11 is snapped onto the outside of the fixing ring 10. In this embodiment, the fixing ring 10 facilitates the connection of the sealing plate 11, and the sealing plate 11 facilitates the splicing of the pipe body 1.

[0029] Reference Figure 1 The positioning shaft 14 is fixedly connected to one side of the sealing plate 11. The positioning hole 12 is adapted to the positioning shaft 14. The fixing bolt 15 is snapped into the inside of the through hole 13. In this embodiment, the positioning shaft 14 facilitates the splicing of the sealing plate 11, the positioning hole 12 facilitates the connection of the positioning shaft 14, and the fixing bolt 15 facilitates the fixed connection of the sealing plate 11.

[0030] The implementation principle of this embodiment is as follows:

[0031] When splicing the pipe body 1, the inclined surface A6 and the inclined surface B7 need to be aligned. The sealing ring 9 is installed inside the sealing groove 8. Then, the pipe body 1 is pushed to move until the inclined surface A6 and the inclined surface B7 are in contact. At this time, the sealing ring 9 is completely engaged inside the sealing groove 8. Finally, the sealing plate 11 is engaged outside the fixing ring 10. The edge of the fixing ring 10 is tapered, and the sealing plate 11 is provided with a corresponding cone plate inside to engage the fixing ring 10. During the splicing of the sealing plate 11, the positioning shaft 14 needs to be aligned with the positioning hole 12 and inserted into the positioning hole 12. When the positioning shaft 14 is fully inserted into the positioning hole 12, the through holes 13 are concentric. At this time, the fixing bolt 15 is installed inside the through hole 13 and the fixing bolt 15 is tightened with a tool. Thus, the splicing of the pipe body 1 is completed.

[0032] Before the pipe body 1 is spliced, the sealing ring 9 can be installed inside the sealing groove 8 in advance. The support frame 2 will also be placed inside the pipe body 1 before splicing. Then, the support ring 5 is connected to the support by using the cooperation of the fixing screw 4 and the screw hole 3. Since the outer diameter of the support ring 5 is larger than the inner diameter of the pipe body 1, the support ring 5 can be restricted to both ends of the pipe body 1 to fix the support frame 2.

[0033] Compared with the prior art, the present invention has the following advantages:

[0034] The screw hole 3, in conjunction with the fixing screw 4, connects the support ring 5 and the support frame 2. The inclined surfaces A6 and B7, in conjunction with the sealing groove 8, facilitate the installation of the sealing ring 9. The addition of the sealing ring 9 prevents water leakage. The fixing ring 10, in conjunction with the sealing plate 11, connects the pipe body 1. The positioning hole 12, in conjunction with the positioning shaft 14, facilitates the splicing of the sealing plate 11. The through hole 13, in conjunction with the fixing bolt 15, secures the sealing plate 11. By using the above structure, the pipe body 1 can be spliced ​​without the use of cement, and no water leakage will occur during use.

[0035] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
