Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage technology, specifically to a sealing structure for a water supply and drainage connecting pipe. Background Technology

[0002] Currently, when using water in RVs, we generally use water pumps to extract water. A water pump is a machine that transports or pressurizes liquids. It transfers the mechanical energy of a prime mover or other external energy to the liquid, increasing its energy. It is mainly used to transport liquids including water, oil, acids and alkalis, emulsions, suspensions, and liquid metals. It can also transport liquid-gas mixtures and liquids containing suspended solids. In water supply and drainage systems, if the drainage point is lower than the outdoor drainage network, or if sewage needs to be discharged from internal drainage ditches or collection tanks, a drainage pump is required.

[0003] For example, according to authorization announcement number CN202223191475.2, this utility model discloses a water pump sealing device, relating to the field of water pump equipment. The device includes a water pump, with a fixed flange fixedly connected to one side of its surface. A first sealing ring is provided between the fixed flange and the water pump. A connecting flange is fixedly connected to one side of the fixed flange via multiple connecting bolts. A sealing cover is fixedly connected to the inner wall of the connecting flange. A second sealing ring is provided between the sealing cover and the connecting flange. A connecting pipe is fixedly connected to the inner wall of the sealing cover. A fixed ring is fixedly connected to one side of the connecting pipe wall, and a third sealing ring is fixedly connected to one side of the fixed ring. This utility model can further reinforce and seal the connection between the water pump's output end and the connecting pipe when the water pump is connected to an external pipeline, effectively preventing leakage due to gaps between the water pump and the connecting pipe, thus improving the water pump's performance.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem that water pumps generally need to be connected to external pipes during use, and that excessive water pump pressure often causes gaps to form between the pump and the connecting pipe due to impact forces, leading to water leakage and reduced pump performance, the sealing device between the pump and the pipe, while supporting the delivery pipe near the pump, does not allow users to easily adjust the spacing of the support device. This significantly limits the use of the pipe support device and makes it inconvenient for users to support pipes with different spacing. Utility Model Content

[0008] As a preferred embodiment of this utility model, the reinforcement mechanism includes a reinforcement plate, the bottom of which is movably connected to both sides of the top of the lifting plate, a reinforcement rod is threadedly connected to the inner wall of the reinforcement plate, a pressure block is movably connected to the inner side of the reinforcement rod via a pin, and a handwheel is fixedly connected to the outer side of the reinforcement rod.

[0009] As a preferred embodiment of this utility model, a transmission groove is provided on the front side of the base plate, and a transmission rod is movably connected to the inner side of the inner wall of the transmission groove through a shaft pin.

[0010] In a preferred embodiment of this utility model, sliding grooves are provided on both sides of the top of the lifting plate, and an adjustment groove is provided at the bottom of the inner wall of the sliding groove. The adjustment groove extends to the front of the lifting plate, and a bidirectional lead screw is movably connected to the rear side of the inner wall of the adjustment groove via a shaft pin. Sliding blocks are threaded to both sides of the surface of the bidirectional lead screw. The top of the surface of the sliding block is slidably connected to the inner wall of the sliding groove, and the bottom of the reinforcing plate is fixedly connected to the top of the sliding block.

[0011] As a preferred embodiment of this utility model, displacement grooves are provided on both sides of the rear side of the bottom of the lifting plate, and an adjusting block is slidably connected to the inner wall of the displacement groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting a first movable rod, a second movable rod, and a lifting plate, allows the first movable rod to move back and forth on the top of the base plate, reducing the distance between the first and second movable rods. This allows the lifting height to support the delivery pipe, solving the problem that while the sealing device between the water pump and the pipeline can support the delivery pipe near the water pump, it is inconvenient for the user to adjust the fixed distance of the support device, thus greatly limiting the use of the pipeline support device and making it inconvenient for the user to support pipelines with different distances.

[0015] 2. This utility model, by setting a movable component, allows the user to move the bottom of the first movable rod towards the second movable rod when the user needs to move the bottom of the first movable rod. Since the movable block is fixedly connected to the bottom of the first movable rod, the movement of the first movable rod will drive the movable block to move towards the second movable rod. The movable component can restrict the movement direction of the movable block, making the movement of the movable block more stable, thereby making the movement of the first movable rod more stable, thus achieving the effect of assisting the movement of the first movable rod.

[0016] 3. This utility model, by setting up a reinforcement mechanism, allows the user to support the conveying pipe with the lifting plate and then rotate the reinforcement rod. Since the reinforcement rod is threadedly connected to the inner wall of the reinforcement plate, the reinforcement rod can move back and forth on the reinforcement plate. The reinforcement rod can drive the pressure block to move towards the conveying pipe, and the pressure block can press the conveying pipe tightly, making it unable to move, thereby achieving the effect of assisting in the reinforcement of the conveying pipe.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4As shown, this utility model provides a sealing structure for a water supply and drainage connecting pipe, including a base plate 1, a support plate 2, a water pump 3, a connecting flange 4, a sealer 5, and a connecting pipe 6. The top left side of the base plate 1 is fixedly connected to the bottom of the support plate 2, the top of the support plate 2 is fixedly connected to the bottom of the water pump 3, the right side of the surface of the water pump 3 is fixedly connected to the left side of the connecting flange 4, the right side of the connecting flange 4 is fixedly connected to the left side of the sealer 5, the left side of the connecting pipe 6 is fixedly connected to the right side of the sealer 5, a first fixing plate 7 is movably connected to the front side of the top of the base plate 1, and the rear side of the top of the base plate 1 is fixedly connected to... There is a second fixed plate 8. The top of the first fixed plate 7 is fixedly connected to the first movable rod 9. The top of the second fixed plate 8 is movably connected to the second movable rod 10 through a pivot pin. The top of the bottom plate 1 is movably connected to the lifting plate 11. The two sides of the bottom front side of the lifting plate 11 are fixedly connected to the top of the second movable rod 10 through pivot pins. The top of the first movable rod 9 is movably connected to the two sides of the bottom rear side of the lifting plate 11. The top of the lifting plate 11 is fixedly connected to the support block 12. The top of the bottom plate 1 is provided with a moving groove (131). The two sides of the top of the lifting plate 11 are fixedly connected to the reinforcing mechanism 14.

[0024] refer to Figure 3 The movable component 13 includes a movable groove 131, and two movable grooves 131 are provided. A movable block 132 is slidably connected to the inner wall of the movable groove 131, and the top of the movable block 132 is fixedly connected to the bottom of the first fixed plate 7.

[0025] As a technical optimization of this utility model, by setting the moving groove 131, when the user needs to move the bottom of the first movable rod 9, the first movable rod 9 is moved towards the second movable rod 10. Since the moving block 132 is fixedly connected to the bottom of the first movable rod 9, the movement of the first movable rod 9 will drive the moving block 132 to move towards the second movable rod 10. The moving groove 131 can restrict the movement direction of the moving block 132, making the movement of the moving block 132 more stable, thereby making the movement of the first movable rod 9 more stable, thus achieving the effect of assisting the movement of the first movable rod 9.

[0026] refer to Figure 4 The reinforcement mechanism 14 includes a reinforcement plate 141. The bottom of the reinforcement plate 141 is movably connected to both sides of the top of the lifting plate 11. A reinforcement rod 142 is threadedly connected to the inner wall of the reinforcement plate 141. A pressure block 143 is movably connected to the inner side of the reinforcement rod 142 through a shaft pin. A handwheel 144 is fixedly connected to the outer side of the reinforcement rod 142.

[0027] As a technical optimization of this utility model, by setting up a reinforcement mechanism 14, when the user supports the conveying pipe with the lifting plate 11, the reinforcement rod 142 is rotated. Since the reinforcement rod 142 is threadedly connected to the inner wall of the reinforcement plate 141, the reinforcement rod 142 can move back and forth on the reinforcement plate 141. The reinforcement rod 142 can drive the pressure block 143 to move towards the conveying pipe. The pressure block 143 can press the conveying pipe tightly, making it unable to move, thereby achieving the effect of assisting in the reinforcement of the conveying pipe.

[0028] refer to Figure 3 The base plate 1 has a transmission groove 15 on its front side. The inner side of the inner wall of the transmission groove 15 is movably connected to the transmission rod 16 by a shaft pin. The surface of the transmission rod 16 is threaded with a connecting block 29. Both sides of the inner wall of the transmission groove 15 have sliding grooves 17. The sliding grooves 17 are connected to the bottom of the inner side of the inner wall of the moving groove 131. The inner wall of the sliding groove 17 is slidably connected to the sliding rod 18. The inner side of the sliding rod 18 is fixedly connected to both sides of the moving block 132.

[0029] As a technical optimization of this utility model, by setting up a transmission groove 15, a transmission rod 16, a moving block 132, a sliding groove 17, and a sliding rod 18, when the user needs to move the first movable rod 9, the transmission rod 16 is rotated first. The transmission groove 15 can restrict the movement direction of the transmission rod 16, making the movement of the transmission rod 16 more stable. When the transmission rod 16 rotates, since the moving block 132 is fixedly connected to the sliding rod 18, and the sliding groove 17 restricts the movement direction of the sliding rod 18, the connecting block 29 will not rotate with the transmission rod 16. As a result, the connecting block 29 can move back and forth inside the transmission groove 15. Since the sliding rod 18 is fixedly connected to the moving block 132, the movement of the connecting block 29 will drive the moving block 132 to move back and forth, thereby achieving the effect of moving the first movable rod 9.

[0030] refer to Figure 4 The top of the lifting plate 11 has sliding grooves 19 on both sides. The bottom of the inner wall of the sliding groove 19 has an adjustment groove 20. The adjustment groove 20 extends to the front of the lifting plate 11. The rear side of the inner wall of the adjustment groove 20 is movably connected to a double-acting screw 21 by a shaft pin. The two sides of the surface of the double-acting screw 21 are threaded with sliding blocks 22. The top of the surface of the sliding block 22 is slidably connected to the inner wall of the sliding groove 19. The bottom of the reinforcing plate 141 is fixedly connected to the top of the sliding block 22.

[0031] As a technical optimization of this utility model, by setting a sliding groove 19, an adjusting groove 20, a bidirectional lead screw 21, and a sliding block 22, when the user needs the reinforcing plate 141 to move towards each other, the bidirectional lead screw 21 is rotated first. Since the sliding groove 19 can restrict the movement direction of the sliding block 22, the sliding block 22 can move towards each other inside the adjusting groove 20. Since the top of the sliding block 22 is fixedly connected to the bottom of the reinforcing plate 141, the reinforcing plate 141 can move on the top of the lifting plate 11. The adjusting groove 20 can restrict the movement direction of the bidirectional lead screw 21, thereby achieving the effect of adjusting the position of the fixed plate.

[0032] refer to Figure 2 The lifting plate 11 has displacement grooves 23 on both sides of the bottom rear side. The inner wall of the displacement groove 23 is slidably connected to the adjusting block 24. The bottom of the adjusting block 24 is fixedly connected to the top of the first movable rod 9.

[0033] As a technical optimization of this utility model, by setting a displacement groove 23 and an adjusting block 24, when the moving block 132 drives the first movable rod 9 to move back and forth, the first movable rod 9 will drive the adjusting block 24 to move back and forth inside the displacement groove 23, so that the lifting plate 11 always remains in a horizontal state. The displacement groove 23 can restrict the movement direction of the adjusting block 24, making the movement of the adjusting block 24 more stable, thereby achieving the effect of assisting the movement of the first movable rod 9.

[0034] refer to Figure 3 A rotating block 25 is fixedly connected to the front of both the bidirectional lead screw 21 and the front of the transmission rod 16. A slot 26 is opened on the front of the rotating block 25. A locking block 27 is slidably connected to the inner wall of the slot 26. An auxiliary block 28 is fixedly connected to the front of the locking block 27.

[0035] As a technical optimization of this utility model, by setting up a rotating block 25, a slot 26, a locking block 27, and an auxiliary block 28, when the user needs to rotate the transmission rod 16 or the bidirectional lead screw 21, the auxiliary block 28 is taken out, the end of the auxiliary block 28 with the locking block 27 is aligned with the slot 26, and then the auxiliary block 28 is moved towards the rotating block 25, so that the locking block 27 is completely moved into the slot 26. The slot 26 can restrict the movement direction of the locking block 27, so that the rotation of the locking block 27 can drive the rotating block 25 to rotate. Since the rotating block 25 is fixedly connected to the bidirectional lead screw 21 and the transmission rod 16, the rotation of the rotating block 25 can drive the bidirectional lead screw 21 and the transmission rod 16 to rotate, thereby achieving the effect of assisting the rotation of the bidirectional lead screw 21 and the transmission rod 16.

[0036] The working principle and usage process of this utility model are as follows: During use, the first movable rod 9 can move back and forth on the top of the base plate 1, reducing the distance between the first movable rod 9 and the second movable rod 10, thus increasing the lifting height and supporting the conveying pipe. When the user needs to move the bottom of the first movable rod 9, it moves towards the second movable rod 10. Since the moving block 132 is fixedly connected to the bottom of the first movable rod 9, the movement of the first movable rod 9 will drive the moving block 132 towards the second movable rod 10. The moving groove 131 restricts the movement direction of the moving block 132, making its movement more stable, and consequently, making the movement of the first movable rod 9 more stable. When the moving block 132 drives the first movable rod 9 to move back and forth, the first movable rod 9 will drive the adjusting block 24 to move back and forth inside the displacement groove 23, keeping the lifting plate 11 horizontal. The displacement groove 23 restricts the movement direction of the adjusting block 24, allowing the adjusting block 24 to move... More stable, when the user needs to move the first movable rod 9, first rotate the transmission rod 16. The transmission groove 15 can restrict the movement direction of the transmission rod 16, making the movement of the transmission rod 16 more stable. When the transmission rod 16 rotates, since the moving block 132 is fixedly connected to the slide rod 18 and the slide groove 17 restricts the movement direction of the slide rod 18, the connecting block 29 will not rotate with the transmission rod 16. Thus, the connecting block 29 can move back and forth inside the transmission groove 15. Since the slide rod 18 is fixedly connected to the moving block 132, the movement of the connecting block 29 will drive the moving block 132 to move back and forth. When the user uses the lifting plate 11 to support the conveying pipe, then rotate the reinforcing rod 142. Since the reinforcing rod 142 is threadedly connected to the inner wall of the reinforcing plate 141, the reinforcing rod 142 can move back and forth on the reinforcing plate 141. The reinforcing rod 142 can drive the pressure block 143 to move towards the conveying pipe. The pressure block 143 can press the conveying pipe tightly, making it unable to move, thereby achieving the effect of auxiliary adjustment.

[0037] In summary, this sealing structure for water supply and drainage connecting pipes, by setting a first movable rod 9, a second movable rod 10, and a lifting plate 11, allows the first movable rod 9 to move back and forth on the top of the base plate 1. This reduces the distance between the first movable rod 9 and the second movable rod 10, allowing the lifting height to support the conveying pipe. This solves the problem that while the sealing device between the water pump and the pipeline can support the conveying pipe near the water pump, it is inconvenient for the user to adjust the fixed spacing of the support device, thus greatly limiting the use of the pipeline support device and making it inconvenient for the user to support pipelines with different spacing.
