Description

Technical Field

[0001] This utility model belongs to the field of plastic steel pipe technology, and specifically relates to an assembled plastic steel pipe structure. Background Technology

[0002] Plastic-coated steel pipe, also known as plastic-coated pipe, steel-plastic composite pipe, or plastic-coated composite steel pipe, is a steel-plastic composite steel pipe with a steel pipe as the base material. A layer of plastic anti-corrosion coating is fused to the inner surface of the steel pipe (base pipe) or to both the inner and outer surfaces through spraying, rolling, dipping, or suction processes. Plastic-coated steel pipe has excellent corrosion resistance and relatively low frictional resistance. Furthermore, its coating itself has good electrical insulation properties and will not cause electrolytic corrosion. Currently, plastic-coated steel pipes require butt joint installation during construction to ensure they form a complete, integrated pipe structure for use.

[0003] Chinese patent with announcement number "CN222503027U" discloses a plastic-coated steel pipe socket connection structure, including a first plastic-coated steel pipe, a second plastic-coated steel pipe, and a socket pipe. The inner wall of the socket pipe is provided with guide plates arranged in an annular pattern at equal intervals. The guide plates have a U-shaped structure design and the opening faces downward. A forward serrated plate is fixedly provided at the top of the inner wall of the guide plate. A fixing ring is detachably installed on the outer wall of the second plastic-coated steel pipe. A movable ring is provided on the outer wall of the fixing ring. The inner wall of the fixing ring is provided with insert plates arranged in an annular pattern at equal intervals.

[0004] However, the above structure still has some shortcomings. When using a corresponding pipe fitting structure for connection and installation, since the pipe fitting structure is a whole, the user needs to pre-fit it onto a plastic steel pipe for positioning and installation. At the same time, the inner width of the pipe fitting is fixed and can only be used with a matching plastic steel pipe. Because it is pre-fitted for installation, the practicality of the structure is reduced, and its installation range is also reduced. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an assembled plastic steel pipe structure to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An assembled plastic-steel pipe structure includes a first plastic-steel pipe and a second plastic-steel pipe. The top end of the first plastic-steel pipe is inserted into the second plastic-steel pipe. A first assembly sleeve is provided on the outer wall of the first plastic-steel pipe. A second assembly sleeve is threaded to one side of the first assembly sleeve. A positioning block is fixedly connected to the outer wall of the second assembly sleeve. A connecting plate is snapped onto the other side of the positioning block. Connecting blocks are fixedly connected to the outer walls of both the first and second assembly sleeves. A screw hole is opened on one side of the connecting block. The position of the connecting block corresponds to the position of the positioning block. A rotating shaft is rotatably connected to the other side of the connecting plate. A screw is fixedly connected to the other side of the rotating shaft. The screw is threaded into the inner side of the screw hole. The first and second plastic-steel pipes are both located inside the first assembly sleeve.

[0008] As a preferred technical solution, a first slot is provided on the other side of the positioning block, a second slot is provided on the inner wall of the first slot, a circular groove is provided on the inner side of the first slot, a first locking block that matches the first slot is fixedly connected to one side of the connecting plate, a second locking block that matches the second slot is fixedly connected to the outer side of the first locking block, and the second locking block is engaged with the inner side of the circular groove.

[0009] As a preferred technical solution, a retaining spring that matches the second retaining block is installed on the inner side of the circular groove. One side of the second retaining block is engaged with the other side of the retaining spring. The second retaining block is engaged with the inner side of the circular groove by the retaining spring. A second rubber pad is fixedly connected to one side of the connecting plate. One side of the second rubber pad is in contact with the other side of the positioning block. The first retaining block is located on the inner side close to the second rubber pad.

[0010] As a preferred technical solution, a limiting block is fixedly connected to the other side of the connecting block on the outer wall of the second assembly sleeve, and a limiting groove matching the limiting block is opened on one side of the connecting block on the outer wall of the first assembly sleeve, and the position of the limiting block and the position of the limiting groove correspond to each other.

[0011] As a preferred technical solution, a second sealing ring is fixedly connected to the other side of the connecting block on the outer wall of the second assembly sleeve. The second sealing ring is located on the inner side of the limiting block, and a sealing groove matching the second sealing ring is opened on one side of the connecting block on the outer wall of the first assembly sleeve. The second sealing ring covers the inner side of the sealing groove.

[0012] As a preferred technical solution, the top end of the first plastic steel pipe is provided with a slot, and the bottom end of the second plastic steel pipe is fixedly connected with an insert plate that matches the slot. The insert plate is inserted into the inside of the slot. The top end of the first plastic steel pipe is fixedly connected with a first sealing ring, which is located on the inside of the insert plate. The position of the first sealing ring corresponds to the position of the bottom end of the second plastic steel pipe.

[0013] As a preferred technical solution, a first rubber pad is fixedly connected to the inner wall of both the first assembly sleeve and the second assembly sleeve. The thickness of the first rubber pad is five millimeters, and the inner side of the first rubber pad is in contact with the outer wall of the first plastic steel pipe.

[0014] In summary, the present invention has the following main advantages:

[0015] Firstly, during use, the first and second plastic steel pipes are assembled using the plug-in principle. After assembly, the user can place the first and second assembly sleeves on the connection point between the two, and then screw the screw into the screw hole. The rotating shaft can make the end of the screw rotate in place, and the first and second assembly sleeves will clamp inward accordingly, thereby effectively protecting and reinforcing the connection point between the first and second plastic steel pipes. It also facilitates the user to fix and assemble plastic steel pipe structures of different widths. When disassembly and maintenance are required later, the screw can be unscrewed. This also solves the inconvenience caused by the previous method of pre-installation.

[0016] Secondly, the presence of the first locking block facilitates the insertion of the second locking block into the circular groove. By adjusting the second locking block to a position that does not correspond to the second locking groove, and then using a retaining spring for secondary locking, displacement of the connecting plate structure can be effectively prevented. The second rubber pad has good anti-slip ability and elasticity. The rebound of the second rubber pad can further improve the stability of the locking point of the second locking block. When it is necessary to disassemble it later, the second locking block is adjusted to a position corresponding to the second locking groove, and then the first locking block can be pulled out directly. This also facilitates the user to disassemble and assemble the connecting plate structure separately, and also facilitates the maintenance of the relative structure on the connecting plate later.

[0024] Example

[0025] refer to Figures 1 to 6 This embodiment of an assembled plastic steel pipe structure includes a first plastic steel pipe 1 and a second plastic steel pipe 2. The top end of the first plastic steel pipe 1 is inserted into the second plastic steel pipe 2. A first assembly sleeve 6 is provided on the outer wall of the first plastic steel pipe 1. A second assembly sleeve 7 is threadedly connected to one side of the first assembly sleeve 6. A positioning block 9 is fixedly connected to the outer wall of the second assembly sleeve 7. A connecting plate 16 is snapped onto the other side of the positioning block 9. Connecting blocks 10 are fixedly connected to the outer walls of both the first assembly sleeve 6 and the second assembly sleeve 7. A screw hole 15 is provided on one side of the connecting block 10. The position of the connecting block 10 corresponds to the position of the positioning block 9. A rotating shaft 20 is rotatably connected to the other side of the connecting plate 16. A screw 21 is fixedly connected to the other side of the rotating shaft 20 and threaded into the screw hole. Inside the first assembly sleeve 6, the first plastic steel pipe 1 and the second plastic steel pipe 2 are both located inside the first assembly sleeve 6. In use, the first plastic steel pipe 1 and the second plastic steel pipe 2 are first assembled by plugging in. After assembly, since the first assembly sleeve 6 and the second assembly sleeve 7 are individual units, it is easier to fit them on the outer wall of the first plastic steel pipe 1. Then, the screw 21 is screwed into the screw hole 15. The rotating shaft 20 can make the end of the screw 21 rotate in place, and the first assembly sleeve 6 and the second assembly sleeve 7 will clamp inward accordingly. This can effectively protect and reinforce the connection point between the first plastic steel pipe 1 and the second plastic steel pipe 2. It also makes it easier for users to fix and assemble plastic steel pipe structures of different widths. When it is necessary to disassemble and maintain them later, the screw 21 can be unscrewed.

[0026] refer to Figures 3 to 5A first slot 11 is provided on the other side of the positioning block 9. A second slot 12 is provided on the inner wall of the first slot 11. A circular groove 13 is provided on the inner side of the first slot 11. A first locking block 17 matching the first slot 11 is fixedly connected to one side of the connecting plate 16. A second locking block 18 matching the second slot 12 is fixedly connected to the outer side of the first locking block 17. The second locking block 18 is engaged with the inner side of the circular groove 13. A retaining spring 14 matching the second locking block 18 is installed on the inner side of the circular groove 13. One side of the second locking block 18 is engaged with the other side of the retaining spring 14. The second locking block 18 is engaged with the inner side of the circular groove 13 through the retaining spring 14. A second rubber pad 19 is fixedly connected to one side of the connecting plate 16. One side of the second rubber pad 19 is in contact with the other side of the positioning block 9. The first locking block 17 is located in contact with the first locking block 17. Near the inner side of the second rubber pad 19, the presence of the first locking block 17 facilitates the insertion of the second locking block 18 into the circular groove 13. The second locking block 18 is adjusted to a position that does not correspond to the second locking groove 12, and then a secondary locking is achieved through the snap ring 14. This effectively prevents displacement of the connecting plate 16 structure. The second rubber pad 19 has good anti-slip ability and elasticity. The rebound of the second rubber pad 19 further improves the stability of the locking point of the second locking block 18. When it needs to be disassembled later, the second locking block 18 is adjusted to a position corresponding to the second locking groove 12, and then the first locking block 17 can be directly pulled out. This also facilitates the user to disassemble and assemble the connecting plate 16 structure separately, and also facilitates the maintenance of the relative structure on the connecting plate 16 later.

[0027] refer to Figures 1 to 6 On the other side of the connecting block 10 on the outer wall of the second assembly sleeve 7, a limiting block 22 is fixedly connected. On one side of the connecting block 10 on the outer wall of the first assembly sleeve 6, a limiting groove 24 matching the limiting block 22 is provided. The positions of the limiting block 22 and the limiting groove 24 correspond to each other. On the other side of the connecting block 10 on the outer wall of the second assembly sleeve 7, a second sealing ring 23 is fixedly connected. The second sealing ring 23 is located on the inner side close to the limiting block 22. On one side of the connecting block 10 on the outer wall of the first assembly sleeve 6, a sealing groove 25 matching the second sealing ring 23 is provided. The second sealing ring 23 covers the inner side of the sealing groove 25. Due to the presence of the limiting block 22, the insertion of the limiting block 22 can effectively improve the stability of the connection between the first assembly sleeve 6 and the second assembly sleeve 7, and can play a good fixing and strengthening effect. The second sealing ring 23 can effectively seal the connection point between the two, thereby playing a good sealing and waterproof effect.

[0028] refer to Figure 2The top end of the first plastic steel pipe 1 is provided with a slot 3, and the bottom end of the second plastic steel pipe 2 is fixedly connected with an insert plate 4 that matches the slot 3. The insert plate 4 is inserted into the inside of the slot 3. The top end of the first plastic steel pipe 1 is fixedly connected with a first sealing ring 5, which is located on the inside of the insert plate 4. The position of the first sealing ring 5 corresponds to the position of the bottom end of the second plastic steel pipe 2. Due to the presence of the insert plate 4, the insertion of the insert plate 4 can effectively assemble the second plastic steel pipe 2 to prevent it from shifting. It also facilitates the user to disassemble the two later for individual maintenance. The first sealing ring 5 can effectively seal the joint between the two, thereby improving the overall sealing performance of the assembled plastic steel pipe.

[0029] refer to Figure 3 and Figure 6 A first rubber pad 8 is fixedly connected to the inner wall of both the first assembly sleeve 6 and the second assembly sleeve 7. The thickness of the first rubber pad 8 is five millimeters. The inner side of the first rubber pad 8 is in contact with the outer wall of the first plastic steel pipe 1. Due to the presence of the first rubber pad 8, which is a rubber product, it has good anti-slip ability and rubber sealing effect. While improving the tighter fit between the first assembly sleeve 6 and the first plastic steel pipe 1, it can also further improve the sealing effect of the joint point of the first plastic steel pipe 1.

[0030] Operating principle and advantages: In use, the first plastic steel pipe 1 and the second plastic steel pipe 2 are first assembled using a plug-in principle. After assembly, because the first assembly sleeve 6 and the second assembly sleeve 7 are individual units, they are more easily fitted onto the outer wall of the first plastic steel pipe 1. Then, the screw 21 is screwed into the screw hole 15. The rotating shaft 20 allows the end of the screw 21 to rotate in place, causing the first assembly sleeve 6 and the second assembly sleeve 7 to clamp inwards. This effectively protects and reinforces the connection point between the first plastic steel pipe 1 and the second plastic steel pipe 2, and also facilitates the user's use of plastic steel pipe structures of different widths. When the assembly is complete and disassembly and maintenance are required later, simply unscrew the screw 21. Due to the presence of the first locking block 17, it is easy for the second locking block 18 to insert into the circular groove 13. Adjust the second locking block 18 so that it does not correspond to the second locking groove 12, and then use the retaining spring 14 for secondary locking. This effectively prevents displacement of the connecting plate 16 structure. The second rubber pad 19 has good anti-slip ability and elasticity. The rebound of the second rubber pad 19 further improves the stability of the locking point of the second locking block 18. When disassembly is required later, simply unscrew the second locking block 17. Adjust block 18 to correspond to the position of the second slot 12, and then directly pull out the first locking block 17. This facilitates the user's later individual disassembly and assembly of the connecting plate 16 structure, and also facilitates the later maintenance of the relative structure on the connecting plate 16. Due to the presence of the limiting block 22, the insertion of the limiting block 22 can effectively improve the stability of the connection between the first assembly sleeve 6 and the second assembly sleeve 7, and can play a good fixing and strengthening role. Its second sealing ring 23 can effectively seal the connection point between the two, thereby playing a good sealing and waterproof role. Due to the presence of the insert plate 4, The insertion of the insert plate 4 can effectively assemble the second plastic steel pipe 2 to prevent it from shifting. It also facilitates the user to disassemble the two parts later for individual maintenance. The first sealing ring 5 can effectively seal the joint point between the two parts, thereby improving the overall sealing performance of the assembled plastic steel pipe. Due to the presence of the first rubber pad 8, which is a rubber product, it has good anti-slip ability and rubber sealing effect. While improving the tighter fit between the first assembly sleeve 6 and the first plastic steel pipe 1, it can also further improve the sealing effect of the joint point of the first plastic steel pipe 1.
