Abstract

This utility model aims to provide a screw-on plug for a water tank, comprising a base and a sealing assembly. The base has a first through hole and is used to mount on an inflatable water tank. The sealing assembly includes a screw cap, a connecting band, and an adapter cylinder. The adapter cylinder has a second and a third through hole that communicate with each other, and the inner diameter of the third through hole is smaller than that of the second through hole. The inner wall of the second through hole is screwed to the outer wall of the base, and the inner wall of the screw cap is screwed to the outer wall of the adapter cylinder near the third through hole. The connecting band is rotatably connected to the base, the adapter cylinder, and the screw cap. Thus, when the inflatable water tank needs to release water at its maximum speed, the adapter cylinder is removed from the base. When it is necessary to reduce the water release speed of the inflatable water tank, the screw cap is unscrewed, and the relatively small diameter of the third through hole can reduce the water release speed. Furthermore, the inner diameters of the first and third through holes are different, thus better adapting to pipes of different diameters.

Description

Technical Field

[0001] This utility model relates to the technical field of water tank accessories, and in particular to a screw cap plug for water tanks. Background Technology

[0002] In order to make it easier for family members to play in the water, European and American families usually place inflatable pools in their yards. By filling the inflatable pools with water, they can temporarily form swimming pools.

[0003] When finished using the inflatable pool, the water needs to be drained, which is currently done by removing the plug at the bottom of the inflatable pool.

[0004] However, existing plugging structures have the following shortcomings in practical use: because the size of the plug and the drain hole is fixed, the draining speed of the aerated water tank is constant and cannot be adjusted according to actual needs; moreover, when users need to reuse the water in the tank, a pipe needs to be connected to the drain hole, but because the drain hole size is fixed, it is difficult to effectively adapt to pipes of various diameters. Therefore, to solve the above shortcomings, the screw-on plug for water tanks proposed in this application is proposed. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a screw cap plug that can change the water discharge speed as needed and can be adapted to water tanks of various diameters.

[0006] The objective of this utility model is achieved through the following technical solution: A screw-on plug for a water tank, comprising: A base, having a first through hole, is used for mounting on an inflatable water tank; and A sealing assembly includes a cap, a connecting band, and an adapter cylinder. The adapter cylinder has a second through hole and a third through hole that communicate with each other. The inner diameter of the third through hole is smaller than the inner diameter of the second through hole. The inner sidewall of the second through hole is screwed to the outer sidewall of the base. The inner sidewall of the cap is screwed to the outer sidewall of the adapter cylinder near the third through hole. The connecting band is rotatably connected to the base, the adapter cylinder, and the cap.

[0007] Optionally, the adapter tube includes a first tube and a second tube, the second tube being coaxially disposed on one end of the first tube, the second through hole being located inside the first tube, and the third through hole being located inside the second tube.

[0008] Optionally, the third through hole extends in the direction of the second through hole to form an internal ring.

[0009] Optionally, the base is provided with an embedded tube.

[0010] Optionally, the bottom of the base is provided with an outward-extending piece for fixing to the inflatable water tank.

[0011] Optionally, a first annular groove is formed between the base and the outwardly extending piece, and one end of the connecting piece is fitted into the first annular groove.

[0012] Optionally, a second annular groove is provided between the first cylinder and the second cylinder, and the middle part of the connecting strip is sleeved in the second annular groove.

[0013] Optionally, the top of the screw cap is provided with a third annular groove, and the end of the connector away from the first annular groove is fitted into the third annular groove.

[0014] Optionally, anti-slip parts are provided on the outer wall of the screw cap and the outer wall of the first cylinder.

[0015] Compared with the prior art, the present invention has at least the following advantages: This utility model relates to a screw-on cap type plug for water tanks, comprising a base and a sealing assembly. The base has a first through hole and is used to mount on an inflatable water tank. The sealing assembly includes a cap, a connecting band, and an adapter cylinder. The adapter cylinder has a second and a third through hole that communicate with each other, with the inner diameter of the third through hole being smaller than that of the second through hole. The inner wall of the second through hole is screwed to the outer wall of the base, and the inner wall of the cap is screwed to the outer wall of the adapter cylinder near the third through hole. The connecting band is rotatably connected to the base, the adapter cylinder, and the cap. Thus, when the inflatable water tank needs to release water at its maximum speed, the adapter cylinder is removed from the base. When it is necessary to reduce the water release speed of the inflatable water tank, the cap is unscrewed, and the relatively small diameter of the third through hole can reduce the water release speed. Furthermore, the inner diameters of the first and third through holes are different, thus better adapting to pipes of different diameters. Attached Figure Description

[0019] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0020] like Figures 1 to 3 As shown, a screw-on plug 10 for a water tank includes a base 100 and a sealing assembly 200. The base 100 has a first through hole 110 and is used to be installed on an inflatable water tank. The sealing assembly 200 includes a screw cap 210, a connecting strip 220, and an adapter cylinder 230. The adapter cylinder 230 has a second through hole 2311 and a third through hole 2321 that are interconnected. The inner diameter of the third through hole 2321 is smaller than the inner diameter of the second through hole 2311. The inner sidewall of the second through hole 2311 is screwed to the outer sidewall of the base 100. The inner sidewall of the screw cap 210 is screwed to the outer sidewall of the adapter cylinder 230 near the third through hole 2321. The connecting strip 220 is rotatably connected to the base 100, the adapter cylinder 230, and the screw cap 210.

[0021] It should be noted that the base 100 is installed on the outer wall of the inflatable water tank by welding, sewing, heat sealing, etc., so that the water storage chamber of the inflatable water tank is connected to the outside through the first through hole 110. Furthermore, the second through hole 2311 and the third through hole 2321 are interconnected, and the inner diameter of the third through hole 2321 is smaller than the inner diameter of the second through hole 2311. An internal thread is formed on the inner wall of the second through hole 2311, and an external thread is formed on the outer wall of the base 100, so that the internal thread of the second through hole 2311 can mate with the external thread of the base 100, allowing the adapter cylinder 230 to be screwed onto the base 100, thus connecting the third through hole 2321 with the first through hole 110. Furthermore, an external thread is provided on the outer wall of the adapter cylinder 230 near the third through hole 2321, and an internal thread is provided on the inner wall of the cap 210. Thus, the cap 210 can be screwed and fixed to the end of the adapter cylinder 230 near the third through hole 2321, thereby blocking the third through hole 2321 and, consequently, the water storage chamber of the inflatable water tank. Furthermore, the cap 210, the adapter cylinder 230, and the base 100 are rotatably connected by a connecting cable 220. Thus, when the inflatable pool needs to release water at maximum speed, the adapter tube 230 is removed from the base 100. When the water release speed needs to be reduced, the cap 210 is unscrewed, and the relatively small diameter of the third through hole 2321 reduces the water release speed. Furthermore, the inner diameter of the first through hole 110 is different from that of the third through hole 2321, thus better accommodating pipes of different diameters. After the user has finished playing in the inflatable pool, the pipe is inserted into the first through hole 110 or the third through hole 2321, allowing the water from the inflatable pool to be diverted for watering plants, effectively improving water utilization and reducing waste.

[0022] like Figure 1 As shown, in one embodiment, the adapter cylinder 230 includes a first cylinder 231 and a second cylinder 232. The second cylinder 232 is coaxially disposed on one end of the first cylinder 231. A second through hole 2311 is located inside the first cylinder 231, and a third through hole 2321 is located inside the second cylinder 232.

[0023] It should be noted that the second cylindrical body 232 and the first cylindrical body 231 are integrally molded plastic structures, and the second cylindrical body 232 and the first cylindrical body 231 are coaxially distributed. The outer diameter of the second cylindrical body 232 is smaller than the outer diameter of the first cylindrical body 231. The second through hole 2311 is located inside the first cylindrical body 231, and the third through hole 2321 is located inside the second cylindrical body 232. External threads are formed on the outer side wall of the second cylindrical body 232, and internal threads are formed on the inner side wall of the first cylindrical body 231.

[0024] like Figure 2As shown, in one embodiment, the third through hole 2321 extends toward the second through hole 2311 to form an inner ring 233.

[0025] It should be noted that when the first cylinder 231 is screwed onto the base 100, the inner ring 233 will be partially inserted into the first through hole 110. In this way, when water flows out of the inflatable pool, it can flow out more effectively from the third through hole 2321.

[0026] like Figure 2 As shown, in one embodiment, a tube 120 is provided inside the base 100.

[0027] It should be noted that the insert 120 is located inside the base 100, and the insert 120 is made of PC material, which is relatively hard, thus providing a certain degree of support strength for the base 100. Furthermore, the base 100 is made of a soft rubber material, such as silicone, so that when the adapter 230 is screwed onto the base 100, the sealing between the adapter 230 and the base 100 can be ensured. In one embodiment, the base 100 is integrally molded onto the outer wall of the insert 120 by injection molding.

[0028] like Figures 1 to 3 As shown, in one embodiment, the bottom of the base 100 is provided with an outwardly extending piece 130, which is used to fix it to the inflatable water tank.

[0029] It should be noted that, in order to reliably mount the base 100 onto the inflatable pool, an integrally molded outward-extending piece 130 is formed on the outer wall of the bottom end of the base 100. The thickness of the outward-extending piece 130 gradually decreases towards the direction away from the base 100. Furthermore, the outward-extending piece 130 has a circular structure. In one embodiment, the outward-extending piece 130 is also made of silicone. Thus, the outward-extending piece 130 can be better welded, sewn, or heat-fused onto the inflatable product.

[0030] like Figure 2 and Figure 3 As shown, in one embodiment, a first annular groove 140 is provided between the base 100 and the outer extension piece 130, and one end of the 220 is fitted into the first annular groove 140.

[0031] It should be noted that one end of the connecting belt 220 is provided with a ring, which fits inside the first annular groove 140. This allows the connecting belt 220 to rotate relative to the first annular groove 140.

[0032] like Figure 2 and Figure 3 As shown, in one embodiment, a second annular groove 234 is provided between the first cylinder 231 and the second cylinder 232, and the middle part of the connecting 220 is sleeved in the second annular groove 234.

[0033] It should be noted that a ring is provided in the middle of the connecting belt 220, which fits into the second ring groove 234, so that the connecting belt 220 can rotate relative to the second ring groove 234.

[0034] like Figure 2 and Figure 3 As shown, in one embodiment, the top of the screw cap 210 is provided with a third annular groove 211, and the end of the 220 away from the first annular groove 140 is fitted into the third annular groove 211.

[0035] It should be noted that a ring is also provided on the other end of the connecting belt 220, which fits snugly into the third annular groove 211. Therefore, the connecting belt 220 has rings at its head and both ends, so that the rings at each position can fit into the corresponding first annular groove 140, second annular groove 234, and third annular groove 211 respectively. In this way, the connecting belt 220 connects the base 100, the adapter cylinder 230, and the cap 210 into a whole structure, which facilitates use and avoids the easy loss of parts.

[0036] like Figure 1 and Figure 3 As shown, in one embodiment, anti-slip parts 201 are provided on the outer side wall of the screw cap 210 and the outer side wall of the first cylinder 231.

[0037] It should be noted that, for example, the anti-slip portion 201 of the screw cap 210 is a plurality of protruding ridges integrally formed on the outer side wall of the screw cap 210. The protruding ridges increase the surface area of ​​the screw cap 210, thereby increasing the friction force for the user to rotate the screw cap 210. Furthermore, for example, the anti-slip portion 201 on the outer side wall of the first cylinder 231 is a plurality of grooves. The grooves increase the contact area, thereby improving the friction force between the user's fingers and the adapter cylinder 230.

[0038] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood as including, but not limited to, locking and fixing with screws / bolts, welding, or bonding with adhesives, wherein the adhesives used can be commercially available finished products. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
