Abstract
Description
Technical Field
[0001] This utility model relates to the field of sheet metal water tank technology, and more specifically, it relates to a snap ring connection structure for sheet metal water tanks. Background Technology
[0002] Currently, the bottom of sheet metal water tanks is mounted on retaining rings, with multiple arc-shaped retaining rings joined together to form a circle. Adjacent retaining rings are connected by connectors, with the ends of the retaining rings supported by the connectors. The middle part of the retaining ring is in direct contact with the ground, creating a height difference between the two ends and the middle part. This causes the outer surface of the sheet metal water tank at the connector to appear concave. For example, Chinese patent application number 2023228286004 discloses a steel-walled water tank where the two ends of the bottom retaining rings are supported by connectors, while the middle part of the retaining ring is in direct contact with the ground. This concave phenomenon is prone to occur on the outer surface of the sheet metal water tank at the connector. Utility Model Content
[0003] To overcome the above shortcomings, this utility model provides a snap ring connection structure for sheet metal water tanks. After the snap ring is installed, all positions are on the same horizontal plane, making it less likely for the outer surface of the sheet metal water tank to become concave, making the pressure inside the water tank more stable, and extending the life of the water tank.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a snap ring connection structure for a sheet metal water tank, including a connecting seat and a connecting member. Both ends of the snap ring are provided with insertion holes. Both ends of the connecting member are respectively inserted into the insertion holes of two adjacent snap rings. The connecting member and the connecting seat are connected together, and the bottom surface of the snap ring and the bottom surface of the connecting seat are on the same plane.
[0005] The retaining rings installed on the sheet metal water tank provide support for the entire tank. The insertion holes at both ends of the retaining rings connect to the connectors, with the connector ends placed in the insertion holes, allowing the retaining ring ends to rest on the ground. The bottom surface of the retaining ring and the bottom surface of the connector are on the same plane, ensuring reliable ground support for both. This increases the support area at the connector location, improving stability and preventing concavity on the outer surface of the sheet metal water tank at that location. After installation, all positions of the retaining rings are on the same horizontal plane, forming surface support rather than point support. This ensures balanced stress on all parts of the tank sidewall, preventing excessive localized stress that could cause localized concavity.
[0006] The snap-ring connection structure of the sheet metal water tank in this patent application ensures that all positions are on the same horizontal plane after the snap-ring is installed, making it less likely for the outer surface of the sheet metal water tank to become concave, resulting in more stable pressure inside the water tank and extending its lifespan.
[0007] Preferably, the connector is provided with a T-shaped slot and the connector is provided with a snap-fit connector, which is fitted and inserted into the T-shaped slot for connection.
[0008] The connector is connected to the T-shaped slot on the connector seat via a snap-fit connector, which is convenient and reliable.
[0009] Preferably, a connecting post is provided at the bottom of the T-shaped slot, and a locking screw is connected between the card connector and the connecting post.
[0010] The locking screw secures the connection between the clamp and the connecting post, fixing the connector in place and ensuring a convenient and reliable connection.
[0011] Preferably, the inner and outer edges of the retaining ring are bent toward each other to form an inner flange and an outer flange, a positioning groove is formed between the inner flange and the outer flange, and an insertion hole is formed between the outer flange and the retaining ring.
[0012] The inward and outward flanges increase the structural strength of the retaining ring, making it less prone to deformation. Simultaneously, the inward and outward flanges facilitate the formation of a positioning groove, which clamps and positions the lower end of the pool wall, ensuring reliable installation. An insertion hole is formed between the outward flange and the retaining ring, facilitating the connection of the connectors. This insertion hole is located outside the positioning groove to prevent interference between the connectors and the pool wall.
[0013] Preferably, the connecting seat is provided with an installation groove, and the sheet metal water tank is provided with a vertical plate, with the lower end of the vertical plate installed in the installation groove.
[0014] The mounting slots facilitate the installation and securing of the uprights.
[0015] Preferably, a drainage hole is provided at the bottom of the mounting groove.
[0016] The drainage holes serve to drain water and prevent water from remaining in the mounting groove and corroding the uprights.
[0017] Preferably, a fastening block is installed on the connecting seat, and a fastening screw is connected between the upright plate and the fastening block.
[0018] Fastening screws connect the upright plate and the fastening block, thereby securing the upright plate to the connecting seat and ensuring a reliable connection.
[0019] Preferably, the connector is provided with a fastening slot, and the fastening block is locked in the fastening slot.
[0020] The fastening block is installed in the fastening slot, ensuring reliable installation and preventing it from easily coming off.
[0021] Preferably, snap-fit ribs are provided on the surface of the connector.
[0022] The snap-fit ribs make the connection between the connector and the retaining ring more stable. On the other hand, the deformation of the outward-facing edge can reduce the width of the positioning groove, further pressing the pool wall.
[0023] As a preferred option, protective covers are installed at the locations of two adjacent retaining rings, and the protective covers cover the gap between the two adjacent retaining rings.
[0024] The protective cover protects the inner tank of the pool, preventing it from getting stuck in the gap between two adjacent retaining rings and causing damage.
[0025] Compared with the prior art, the beneficial effects of this utility model are: (1) The snap ring connection structure of the iron sheet water tank in this patent application ensures that all positions are on the same horizontal plane after the snap ring is installed, making it less likely for the outer surface of the iron sheet water tank to have an inward concavity, making the pressure inside the water tank more stable and extending the life of the water tank; (2) The snap ring protrusion is provided on the surface of the connector, which makes the fixing of the connector and the snap ring more stable on the one hand, and on the other hand, the width of the positioning groove can be reduced by the deformation of the outward flange, further pressing the water tank wall.

[0031] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:
[0032] Example 1: A snap-ring connection structure for a sheet metal water tank (see...) Figure 1 , Figure 2 , Figure 3The device includes a connecting base 1 and a connecting piece 2, which are connected together. The connecting piece 2 is located inside the connecting base 1. Each end of a retaining ring 3 has a insertion hole 4. The two ends of the connecting piece 2 are inserted into the insertion holes 4 of two adjacent retaining rings 3, with a gap 25 between adjacent retaining rings 3. The bottom surface of the retaining ring 3 and the bottom surface of the connecting base 1 are on the same plane. The bottom surfaces of the retaining rings 3 are supported on the ground, and all the bottom surfaces of the retaining rings 3 are on the same supporting plane. The retaining rings 3 have an arc-shaped structure, and all the retaining rings 3 are connected end-to-end through the connecting piece 2 to form a ring.
[0033] A T-shaped slot 5 is provided on the connector 1, and a T-shaped snap-fit connector 6 is provided on the connector 2. The snap-fit connector 6 is fitted and inserted into the T-shaped slot 5. The T-shaped slot 5 is located on the inner edge of the connector 1 and on the bottom surface of the connector 1, extending through to the inner wall of the connector 1. A connecting post 7 is provided at the bottom of the T-shaped slot 5. The side wall of the connecting post 7 and the inner wall of the T-shaped slot 5 are connected by a connecting rib 8 to improve the structural strength of the connecting post 7. A locking screw 9 is connected between the snap-fit connector 6 and the connecting post 7. A countersunk hole 10 is provided on the end face of the snap-fit connector 6, and the nut end of the locking screw 9 is placed in the countersunk hole 10.
[0034] The connector 2 has a long strip structure. A snap-fit rib 11 is provided on the surface of the connector 2. The snap-fit rib 11 and the snap-fit connector 6 are integral with the connector 2. The snap-fit rib 11 is snapped onto the inner wall of the insertion hole 4. The inner and outer edges of the retaining ring 3 are bent towards each other to form an inner flange 12 and an outer flange 13. Both the inner flange 12 and the outer flange 13 have an inverted U-shaped structure. The edges of the inner flange 12 and the outer flange 13 are bent inward to form a snap-fit edge 14. A positioning groove 15 is formed between the inner flange 12 and the outer flange 13, with the opening of the positioning groove 15 facing upward. The insertion hole 4 is formed between the outer flange 13 and the retaining ring 3. The snap-fit edge 14 serves as a limiting element. When the end of the connector 2 is inserted into the insertion hole 4, the snap-fit edge 14 is snapped onto the side wall of the connector 2, preventing the connector 2 from moving vertically.
[0035] The inner flange 12 and outer flange 13 help increase the structural strength of the retaining ring 3, making it less prone to deformation. Simultaneously, the inner flange 12 and outer flange 13 facilitate the formation of the positioning groove 15, which clamps and positions the lower end of the pool wall, ensuring reliable installation of the pool. An insertion hole 4 is formed between the outer flange 13 and the retaining ring 3, facilitating the connection of the connector 2. The insertion hole 4 is located around the positioning groove 15 to prevent interference between the connector 2 and the pool wall.
[0036] The connector 2 has snap-fit ribs 11 on its surface. This makes the connection between the connector 2 and the retaining ring 3 more stable. On the other hand, the deformation of the outward flange 13 can reduce the width of the positioning groove 15, further pressing the pool wall. The width of the connector 2 gradually decreases towards the pointed end, making it easier to insert the connector 2 into the insertion hole 4.
[0037] A mounting groove 16 is provided on the connecting seat 1, and a vertical plate 17 is provided on the sheet metal water tank. The lower end of the vertical plate 17 is installed in the mounting groove 16. A drain hole 18 is provided at the bottom of the mounting groove 16. The drain hole 18 serves to drain water and prevent water from remaining in the mounting groove 16 and thus corroding the vertical plate 17. A bearing plane is provided on the bottom surface of the connecting seat 1, which corresponds to the mounting groove 16. The lower end of the vertical plate 17 is installed in the mounting groove 16, and the bearing plane supports the ground to bear the pressure of the vertical plate 17, ensuring the stability of the connecting seat 1.
[0038] A fastening block 19 is installed on the connecting seat 1, and a fastening screw 20 connects the upright plate 17 and the fastening block 19. The fastening block 19 is a metal part with good structural strength, reliable connection, and long service life. A fastening slot 21 is provided on the connecting seat 1, and the fastening block 19 is locked in the fastening slot 21. The fastening slot 21 is located on the bottom surface of the connecting seat 1, and the fastening block 19 is tightly inserted into the fastening slot 21. A threaded hole 22 is provided on the fastening block 1. An avoidance notch 23 is provided on the upper surface of the connecting seat 1, and a connecting hole 24 is provided on the side wall of the avoidance notch 23. A fastening hole is provided at the bottom of the upright plate 17. The connecting hole 24, the fastening hole, and the threaded hole 22 are correspondingly arranged. The fastening screw 20 passes through the connecting hole 24 and the fastening hole and is threadedly connected and fastened to the threaded hole 22 on the fastening block 19. A protrusion 26 is provided on the upper surface of the connecting seat 1. The protrusion 26 is correspondingly arranged with the fastening slot 21 to ensure the structural strength of the fastening slot 21.
[0039] The bottom surface of the connecting seat 1 is provided with several horizontally and vertically arranged reinforcing ribs 27, which are staggered. The arrangement of the reinforcing ribs 27 helps to improve the structural strength of the entire connecting seat 1. Protective cover plates 28 are arranged at the two adjacent retaining rings 3. The protective cover plates 28 are arc-shaped and cover the gap 25 between the two adjacent retaining rings 3. The protective cover plates 28 protect the inner tank of the pool and prevent the inner tank from getting stuck in the gap 25 between the two adjacent retaining rings 3 and causing damage.
[0040] The retaining ring 3 installed on the sheet metal water tank supports the entire tank. The insertion holes 4 at both ends of the retaining ring 3 are inserted into the connector 2, with the end of the connector 2 placed in the insertion hole 4, allowing the end of the retaining ring 3 to be supported on the ground. The bottom surface of the retaining ring 3 and the bottom surface of the connector 1 are on the same plane, ensuring that both the connector 1 and the retaining ring 3 are reliably supported on the ground. This increases the support area at the connector 2 position, thereby improving the stability of the support and preventing indentation of the outer surface of the sheet metal water tank at this location. After installation, all positions of the retaining ring 3 are on the same horizontal plane, forming surface support rather than point support. This ensures balanced force on all parts of the tank sidewall, preventing excessive localized stress that could cause localized indentation of the tank sidewall.
[0041] The retaining ring 3 connection structure of the sheet metal water tank in this patent application ensures that all positions are on the same horizontal plane after the retaining ring 3 is installed, making it less likely for the outer surface of the sheet metal water tank to become concave, resulting in more stable pressure inside the water tank and extending the life of the water tank.

The retaining rings 3 have an arc-shaped structure, and all the retaining rings 3 are connected end-to-end through the connecting piece 2 to form a ring.
[0043] A T-shaped slot 5 is provided on the connector 1, and a T-shaped snap-fit connector 6 is provided on the connector 2. The snap-fit connector 6 is fitted into the T-shaped slot 5 for insertion. A pad 29 is provided at the bottom of the snap-fit connector 6. The height of the connector 2 can be adjusted by replacing the pads 29 with different thicknesses to accommodate the installation of snap rings 3 of different sizes, ensuring that the bottom surface of the snap ring 3 and the bottom surface of the connector 1 are on the same plane. The T-shaped slot 5 is located at the inner edge of the connector 1 and is located on the bottom surface of the connector 1, extending through to the inner wall of the connector 1. A connecting post 7 is provided at the bottom of the T-shaped slot 5. The side wall of the connecting post 7 and the inner wall of the T-shaped slot 5 are connected by a connecting rib 8 to improve the structural strength of the connecting post 7.
