Description

Technical Field

[0001] This application relates to the field of water tank storage pipe connection technology, and in particular to a high-sealing water tank storage pipe connection structure. Background Technology

[0002] A water tank is a container used to store water. It consists of a tank body, inlet and outlet, and drain, and serves functions such as water storage, pressure stabilization, and water supply. In daily life, water tanks are used in residential building water supply, fire protection systems, and industrial cooling. The water tank's storage pipe is used to connect the water tank to other equipment or pipelines to achieve material transfer and distribution. Its connection structure mainly includes connectors, sealing rings, and fasteners.

[0003] When connecting the water tank and the storage pipe, first align the connector with the water tank interface and the pipe interface, place the sealing ring to ensure the seal, and then use fasteners to tighten the connection of the components. After checking that all components are installed in place and there is no looseness, open the valve to test the connection seal and water flow to ensure that the storage pipe connection structure is operating normally and realizes the material transfer between the water tank and external equipment.

[0004] In existing technologies, the connection structure of water tank storage pipes lacks a quick-locking component in terms of docking and locking. It requires multiple manual tightenings of components, which reduces work efficiency. Furthermore, the locking method is laborious, and the connection is unstable and unreliable. It also lacks an automatic reset and locking structure, making it prone to loosening and falling off under material transmission vibration. This makes it difficult to ensure a stable connection, resulting in reduced sealing performance and easy leakage, which affects the stability and safety of material transmission. Therefore, a high-sealing water tank storage pipe connection structure is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a high-sealing water tank storage pipe connection structure, which aims to improve the problems of low operation efficiency, laborious locking process, poor connection stability, and easy loosening under vibration due to the lack of an automatic locking structure, which leads to poor sealing and leakage risk in material transmission.

[0006] The high-sealing water tank storage pipe connection structure provided in this application adopts the following technical solution:

[0007] A high-sealing water tank storage pipe connection structure includes a water tank pipe, a connecting pipe slidably connected to the inner side of the water tank pipe, a locking connecting block fixedly connected to the outer side of the water tank pipe and the connecting pipe, a mating protrusion fixedly connected to the outer side of the locking connecting block, an outer side of one mating protrusion slidably connected to the inner side of another locking connecting block, a connecting locking mechanism rotatably connected to the inner side of the mating protrusion, and a quick-release leak-proof mechanism slidably connected to the outer side of the water tank pipe and the connecting pipe.

[0008] The connection locking mechanism includes a semi-circular locking block, the outer side of which is slidably connected to the connection point of the two locking connecting blocks. An unlocking lever is fixedly connected to the outer side of the semi-circular locking block, and a reset locking component is rotatably connected to the inner side of the middle section of the unlocking lever.

[0009] Through the above technical solution: the water tank pipe and the connecting pipe are tightly connected through a double locking structure. When the semi-circular locking block is tilted, it can effectively prevent loosening. The quick-release leak-proof mechanism, together with the sealing ring, forms a multi-layer seal. It is easy to disassemble and assemble and has good sealing performance, making it suitable for material conveying under various working conditions.

[0010] As a further description of the above technical solution:

[0011] The reset locking assembly includes a fixed shaft, the outer side of which is fixedly connected to the inner side of the locking connecting block. A locking tube is rotatably connected to the outer side of the fixed shaft. A locking slide rod is slidably connected to the inner side of the locking tube. One end of the locking slide rod is rotatably connected to the inner side of the middle section of the unlocking lever. A limit slide plate is fixedly connected to the end of the locking slide rod away from the unlocking lever. The outer side of the limit slide plate is slidably connected to the inner side of the locking tube.

[0012] Through the above technical solution: in the reset locking assembly, the fixed shaft provides stable support for the locking tube. When the locking slide rod slides inside the locking tube, the semi-circular block automatically maintains the locked state through the cooperation of the limiting slide plate and the reset locking spring. The operation is convenient and the locking is firm, ensuring the connection structure is stable and reliable.

[0013] As a further description of the above technical solution:

[0014] A reset locking spring is sleeved on the outer side of the locking slide rod. One end of the reset locking spring is fixedly connected to the outer side of the limiting slide plate, and the other end of the reset locking spring is fixedly connected to the inner side of the locking tube.

[0015] The above technical solution involves a reset locking spring on the outside of the locking slide, with one end connected to the limiting slide plate and the other end connected to the locking tube. The elastic reset force keeps the semi-circular block in an inclined locking state, which can automatically compensate for component wear and ensure the sealing and stability of the connection structure during long-term use. It also makes unlocking easier and reset quick during operation.

[0016] As a further description of the above technical solution:

[0017] The quick-release leak-proof mechanism includes a locking sleeve, the inner side of which is slidably connected to the outer side of the water tank pipe. A groove is provided on the outer side of the water tank pipe, and a locking bead is provided on the inner side of the groove. A hemispherical groove is provided on the outer side of the connecting pipe. The bottom of the locking bead contacts the hemispherical groove of the connecting pipe, and the inner side of the locking sleeve contacts the top of the locking bead.

[0018] Through the above technical solution: in the quick-release leak-proof mechanism, the locking sleeve slides and squeezes the locking bead into the hemispherical groove of the connecting pipe to form an axial locking force, which, together with the sealing ring, achieves radial sealing. It can be operated with one hand to complete quick connection and quick disconnection. In the locked state, the vibration resistance is improved, effectively preventing connection loosening and media leakage caused by vibration.

[0019] As a further description of the above technical solution:

[0020] A locking spring is fitted inside the space between the water tank pipe and the locking bead. One end of the locking spring is fixedly connected to the inside of the locking sleeve, and the other end of the locking spring is fixedly connected to the outside of the water tank pipe. A mating sealing ring is fixedly connected to the outside of the locking sleeve, and the outside of the mating sealing ring is in contact with the outside of the connecting pipe.

[0021] Through the above technical solution: the locking spring provides outward elastic force to the locking sleeve, pushing the locking bead into the hemispherical groove of the connecting tube to form a self-holding lock. The mating sealing ring is tightly fitted to the outside of the connecting tube under the spring pressure. The dual structure realizes quick connection and efficient leak prevention, improving sealing reliability and connection stability.

[0022] As a further description of the above technical solution:

[0023] A disconnection and leak prevention assembly is fixedly connected to the inner side of the water tank pipe and the connecting pipe. The disconnection and leak prevention assembly includes a fixing ring. The outer side of the fixing ring is fixedly connected to the inner side of the water tank pipe. A leak prevention sliding rod is slidably connected to the inner side of the fixing ring. A conical plug is fixedly connected to one end of the leak prevention sliding rod, and a limit block is fixedly connected to the other end of the leak prevention sliding rod.

[0024] The above technical solution involves a locking spring that pushes a locking sleeve to compress a locking bead, causing it to fit tightly into the hemispherical groove of the connecting pipe, thus creating a self-holding locking force. Under spring pressure, the mating sealing ring forms an annular sealing band with the outside of the connecting pipe. This dual structure enables rapid connection and leak prevention, and is resistant to high-pressure impact and aging.

[0025] As a further description of the above technical solution:

[0026] An anti-leakage reset spring is fitted on the outer side of the anti-leakage sliding rod. One end of the anti-leakage reset spring is fixedly connected to the outer side of the conical plug, and the other end of the anti-leakage reset spring is fixedly connected to the outer side of the fixing ring.

[0027] Through the above technical solution: the anti-leakage reset spring uses elastic pre-tightening force to make the conical plug fit tightly against the pipe opening, forming the first sealing barrier; when the connecting pipe is inserted, the spring is compressed to open the channel and allow the medium to flow smoothly; after disconnection, the spring immediately resets and pushes the plug to close the pipe opening, realizing automatic anti-leakage and avoiding medium dripping and environmental pollution.

[0028] As a further description of the above technical solution:

[0029] A leak-proof rubber ring is fixedly connected to the outer side of the leak-proof reset spring. When the leak-proof rubber ring is not connected, it is in contact with the plug of the water tank pipe. A front top unsealing protrusion is fixedly connected to the outer side of the leak-proof reset spring. The outer side of the front top unsealing protrusion is in contact with the outer side of another conical plug.

[0030] The above technical solution utilizes a leak-proof rubber ring on the outside of the leak-proof reset spring to tightly seal the water tank pipe plug when not connected, enhancing the seal. The front unsealing protrusion pushes the conical plug during connection, clearing the passage. Together, these two elements achieve a tight seal when not connected and rapid unsealing when connected, effectively preventing material leakage.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. In this utility model, the connecting locking mechanism drives the semi-circular locking block to rotate by pulling the unlocking lever. When unlocking, the semi-circular locking block rotates to the horizontal position. When locking, it returns to the tilt position under the action of the reset locking spring. In the reset locking assembly, the locking slide rod slides inside the locking tube. The limiting slide plate cooperates with the reset locking spring to keep the semi-circular locking block in the locked state automatically. This achieves quick docking and reliable locking of the water tank pipe and the connecting pipe. The operation is convenient and the locking is firm, ensuring the stability and reliability of the connection structure, effectively preventing loosening and falling off, and ensuring the sealing and stability during material transmission.

[0033] 2. In this utility model, the quick-release leak-proof mechanism pushes the locking sleeve, and uses its inner protrusion to squeeze the locking bead into the hemispherical groove of the connecting pipe. With the help of the locking spring, it achieves automatic locking. When the locking sleeve slides, it drives the mating sealing ring to adhere to the outside of the connecting pipe to form a seal. Pulling the locking sleeve outward will release the locking bead and achieve quick disassembly. This enables quick connection and leak prevention between the water tank pipe and the connecting pipe. It can be operated with one hand. The locked state has good vibration resistance and can effectively prevent loosening and media leakage caused by vibration. It is also resistant to high pressure impact and aging. Attached Figure Description

[0040] The following combination Figures 1-5 This application will be described in further detail below.

[0041] Example: High-sealing water tank storage pipe connection structure, refer to Figures 1 to 3 The system includes a water tank pipe 1, which provides space for material storage and conveying. It works with connecting pipe 2 to achieve connection, sealing and leak prevention functions. The inner side of the water tank pipe 1 is slidably connected to the connecting pipe 2. Through the slidable connection with the water tank pipe 1, it works with various mechanisms to achieve flexible docking, reliable locking and efficient sealing, ensuring smooth material transmission and preventing leakage. The outer sides of the water tank pipe 1 and the connecting pipe 2 are fixedly connected to a locking connecting block 4. The locking connecting block 4 works with the docking protrusion 5 to achieve a stable connection and precise positioning between the two, preventing the water pipe connection from loosening and falling off or rotating relative to each other during pressurization, which could lead to breakage and leakage. The outer side of the locking connecting block 4 is fixedly connected to the docking protrusion 5. The docking protrusion 5 can be precisely inserted into the inner side of the locking connecting block 4. Working together with the connection locking mechanism 6, it enables the water tank pipe 1 and the connecting pipe 2 to quickly dock and reliably lock. The outer side of one docking protrusion 5 is slidably connected to the inner side of another locking connecting block 4. The inner side of the docking protrusion 5 is rotatably connected to the connection locking mechanism 6. The outer sides of the water tank pipe 1 and the connecting pipe 2 are slidably connected to a quick-release leak prevention mechanism 3.

[0042] The connecting locking mechanism 6 includes a semi-circular locking block 61. After the two semi-circular locking blocks 61 are docked, they remain tilted in the groove of the locking connecting block 4 under normal conditions, so that the two locking connecting blocks 4 cannot be pulled apart, thus achieving locking. When the two semi-circular locking blocks 61 are rotated to a horizontal state, the blocking state is released, and the locking connecting blocks 4 can be pulled apart to both sides to achieve quick separation. The outer side of the semi-circular locking block 61 is slidably connected to the connection point of the two locking connecting blocks 4. The outer side of the semi-circular locking block 61 is fixedly connected to an unlocking lever 62. The unlocking lever 62 allows the operator to unlock by turning it. The middle inner side of the unlocking lever 62 is rotatably connected to a reset locking component 63.

[0043] Specifically, during installation, slide the connecting pipe 2 along the inside of the water tank pipe 1. The locking bead 32 of the quick-release leak-proof mechanism 3 is engaged in the hemispherical groove of the connecting pipe 2 under the action of the spring. Then, insert the mating protrusion 5 into the locking connecting block 4, and pull the unlocking lever 62 to make the semi-circular block 61 horizontal. After releasing, the semi-circular block 61 returns to its tilted position, completing the locking connection.

[0044] The reset locking assembly 63 includes a fixed shaft 631, which provides stable rotational support for the locking tube 632. The outer side of the fixed shaft 631 is fixedly connected to the inner side of the locking connecting block 4. The outer side of the fixed shaft 631 is rotatably connected to the locking tube 632, which is used to accommodate the internal reset structure and provide protection and guidance. The inner side of the locking tube 632 is slidably connected to a locking slide rod 633. Under the action of the reset locking spring 635, the locking slide rod 633 can achieve telescopic movement to complete the locking and unlocking actions. One end of the locking slide rod 633 is rotatably connected to the inner side of the middle section of the unlocking pull rod 62. The end of the locking slide rod 633 away from the unlocking pull rod 62 is fixedly connected to a limiting slide plate 634. The limiting slide plate 634 can ensure that the locking slide rod 633 will not come out during the sliding process and can effectively transmit the elastic force of the reset locking spring 635. The outer side of the limiting slide plate 634 is slidably connected to the inner side of the locking tube 632.

[0045] Specifically, when the unlocking lever 62 is pulled, the locking slide 633 slides within the locking tube 632, compressing the reset locking spring 635, causing the semi-circular block 61 to rotate to a horizontal unlock position. After the unlocking lever is released, the reset locking spring 635 pushes the limit slide plate 634, causing the locking slide 633 to reset, thus restoring the semi-circular block 61 to its tilted locking state.

[0046] A reset locking spring 635 is sleeved on the outside of the locking slide 633. The reset locking spring 635 can provide sufficient elastic force to reset the locking slide 633, so that the semi-circular block 61 always remains tilted, maintaining a stable and sealed connection between the two pipes, and maintaining stable elastic performance during long-term use. One end of the reset locking spring 635 is fixedly connected to the outside of the limiting slide 634, and the other end of the reset locking spring 635 is fixedly connected to the inside of the locking tube 632.

[0047] Specifically, when the unlocking lever 62 is pulled, the locking slide 633 is driven to compress the reset locking spring 635, causing the semi-circular block 61 to change from tilted to horizontal, thus releasing the lock on the locking connecting block 4. When the unlocking lever 62 is released, the reset locking spring 635 releases its elasticity, pushing the limit slide 634 and the locking slide 633 to reset, and the semi-circular block 61 returns to its tilt, relocking the two connecting blocks.

[0048] Reference Figure 1 , Figure 4 and Figure 5 The quick-release leak-proof mechanism 3 includes a locking sleeve 31. The inner side of the locking sleeve 31 is provided with a groove and a boss, which are used to cooperate with the locking bead 32 and the locking engagement spring 33 to realize the operation of locking when released and unlocking when pulled out. The inner side of the locking sleeve 31 is slidably connected to the outer side of the water tank pipe 1. The outer side of the water tank pipe 1 is provided with a groove. The inner side of the groove of the water tank pipe 1 is provided with a locking bead 32. Under the action of the locking engagement spring 33 and the locking sleeve 31, the locking bead 32 stably squeezes the hemispherical groove of the connecting pipe 2, realizing the quick locking of the water tank pipe 1 and the connecting pipe 2, preventing the connecting pipe 2 from loosening and falling off and the connection from being unstable. At the same time, it assists in docking the sealing ring 34 to enhance the sealing of the connection part. The outer side of the connecting pipe 2 is provided with a hemispherical groove. The bottom of the locking bead 32 contacts the hemispherical groove of the connecting pipe 2, and the inner side of the locking sleeve 31 contacts the top of the locking bead 32.

[0049] Specifically, the connecting pipe 2 is inserted into the water tank pipe 1. The locking bead 32 is pressed against the outside of the connecting pipe 2 by the locking spring 33. The locking sleeve 31 is pushed, and its inner boss squeezes the locking bead 32 into the hemispherical groove of the connecting pipe 2. At this time, the mating sealing ring 34 is attached to the connecting pipe 2. The locking sleeve 31 is pulled outward, and the boss releases the locking bead 32, thus releasing the lock.

[0050] A locking spring 33 is fitted inside the space between the water tank pipe 1 and the locking bead 32. The locking spring 33 provides outward elastic force to the locking sleeve 31. Under the pressure of the protrusion of the locking sleeve 31, the locking bead 32 can automatically lock into the hemispherical groove when the connecting pipe 2 is inserted, thus achieving quick locking. One end of the locking spring 33 is fixedly connected to the inner side of the locking sleeve 31, and the other end of the locking spring 33 is fixedly connected to the outer side of the water tank pipe 1. A mating sealing ring 34 is fixedly connected to the outer side of the locking sleeve 31. When the locking sleeve 31 slides to the designated position, the mating sealing ring 34 can tightly fit the outer side of the connecting pipe 2 to form a sealing barrier to prevent material leakage. The outer side of the mating sealing ring 34 is in contact with the outer side of the connecting pipe 2.

[0051] Specifically, during connection, the connecting pipe 2 is inserted into the water tank pipe 1. The locking spring 33 pushes the locking sleeve 31 to make the locking bead 32 press against the connecting pipe 2. Continue to push the connecting pipe 2 in. After the hemispherical groove is aligned with the locking bead 32, the boss of the locking sleeve 31 squeezes the locking bead 32 into the groove. At the same time, it drives the mating sealing ring 34 to fit against the outside of the connecting pipe 2, thus completing the locking and sealing.

[0052] A leak-proof assembly 35 is fixedly connected to the inner side of the water tank pipe 1 and the connecting pipe 2. The leak-proof assembly 35 includes a fixing ring 351, which provides a stable sliding guide for the leak-proof sliding rod 352. The outer side of the fixing ring 351 is fixedly connected to the inner side of the water tank pipe 1, and the inner side of the fixing ring 351 is slidably connected to the leak-proof sliding rod 352. Under the action of the leak-proof reset spring 356, the leak-proof sliding rod 352 drives the conical plug 353 to seal the opening of the water tank pipe 1 to prevent material leakage. During connection, it can be released by the front unsealing protrusion 357. To ensure smooth material conveying, a conical plug 353 is fixedly connected to one end of the anti-leakage slide rod 352. The conical plug 353 can fit tightly with the pipe opening of the water tank pipe 1. Under the action of the anti-leakage reset spring 356, it can effectively seal the pipe opening and prevent material leakage. A limit block 355 is fixedly connected to the other end of the anti-leakage slide rod 352. The limit block 355 limits the sliding stroke of the anti-leakage slide rod 352. Together with the anti-leakage reset spring 356 and the conical plug 353, it ensures that the anti-leakage component 35 works normally and achieves reliable leak prevention.

[0053] Specifically, when not connected, the anti-leakage reset spring 356 pushes the anti-leakage slide bar 352, causing the conical block 353 to tightly seal the water tank pipe 1 opening. During the insertion of the connecting pipe 2, its end pushes the front unsealing protrusion 357, causing the anti-leakage slide bar 352 to compress the spring and retract, the conical block 353 to retract, releasing the seal and allowing the material to pass through. The limit block 355 restricts the slide bar's stroke.

[0054] An anti-leakage reset spring 356 is sleeved on the outside of the anti-leakage slide rod 352. The anti-leakage reset spring 356 can provide sufficient elastic force to keep the conical plug 353 in the position of sealing the pipe opening. At the same time, it can be compressed when the connecting pipe 2 is inserted, so that the conical plug 353 can retract. One end of the anti-leakage reset spring 356 is fixedly connected to the outside of the conical plug 353, and the other end of the anti-leakage reset spring 356 is fixedly connected to the outside of the fixing ring 351.

[0055] Specifically, when not connected, the anti-leakage reset spring 356 pushes the conical plug 353 to seal the opening of the water tank pipe 1. When the connecting pipe 2 is inserted, its end pushes the front unsealing protrusion 357, which drives the anti-leakage sliding rod 352 to compress the spring, causing the conical plug 353 to retract and release the seal. After the connecting pipe 2 is pulled out, the spring resets and pushes the conical plug 353 to reseal the pipe opening.

[0056] A leak-proof rubber ring 354 is fixedly connected to the outside of the leak-proof reset spring 356. When not connected, the leak-proof rubber ring 354 further enhances the sealing effect between the conical plug 353 and the water tank pipe 1 plug, preventing minor leaks. When not connected, the leak-proof rubber ring 354 is in contact with the water tank pipe 1 plug. A front top unsealing protrusion 357 is fixedly connected to the outside of the leak-proof reset spring 356. When the connecting pipe 2 is inserted, it can contact the outside of another conical plug 353 and push it to move, realizing the unsealing action, so that the material can pass smoothly through the connection part. The outside of the front top unsealing protrusion 357 is in contact with the outside of another conical plug 353.

[0057] Specifically, when not connected, the leak-proof rubber ring 354 is tightly attached to the plug of the water tank pipe 1, and works with the conical plug 353 to enhance the seal. When the connecting pipe 2 is inserted, its end pushes the front unsealing protrusion 357, which drives the leak-proof reset spring 356 to compress, causing the conical plug 353 to retract, and the leak-proof rubber ring 354 moves forward to release the seal, allowing materials to pass through the connection point.

[0058] The implementation principle of this application embodiment is as follows: When in use, the connecting pipe 2 is first slowly slid into the inner side of the water tank pipe 1. At this time, the locking bead 32 in the groove of the water tank pipe 1 is slightly popped out under the initial elastic force of the locking spring 33. When the connecting pipe 2 is continuously pushed in and its outer hemispherical groove is precisely aligned with the locking bead 32, the operator holds the locking sleeve 31 with his hand and pushes it in the connection direction. The groove and boss structure on the inner side of the locking sleeve 31 squeeze the locking bead 32, so that it is completely inserted into the hemispherical groove of the connecting pipe 2, and the initial positioning is achieved. At the same time, the mating sealing ring 34 on the outer side of the locking sleeve 31 is tightly attached to the outer side of the connecting pipe 2, forming the first sealing barrier.

[0059] Then, align the two mating protrusions 5 and insert them into the corresponding sliding grooves inside the locking connecting block 4. At this time, pull the unlocking lever 62 to drive the semi-circular locking block 61 fixedly connected to it to rotate synchronously, so that the two semi-circular locking blocks 61, which were originally in an inclined state, gradually turn to horizontal. When the semi-circular locking blocks 61 are horizontal, release the unlocking lever 62, and the reset locking spring 635 immediately releases its elastic force, pushing the locking slide bar 633 to drive the semi-circular locking blocks 61 back to the inclined state, firmly locking the locking connecting block 4, and completing the stable locking.

[0060] During the process of inserting the connecting pipe 2 into the water tank pipe 1, the end of the connecting pipe 2 first contacts the front top unsealing protrusion 357. As the insertion depth increases, the front top unsealing protrusion 357 is pushed to move the anti-leakage sliding rod 352 backward, compressing the anti-leakage reset spring 356, causing the conical block 353 that originally blocked the opening of the water tank pipe 1 to gradually retract, releasing the blockage on the opening, and allowing the material to be smoothly transferred through the connection part.

[0061] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
