Description

Technical Field

[0001] The utility model relates to a pre-buried box body, in particular to a highly sealed waterproof and drainage pre-buried box body. Background Art

[0002] A pre-embedded faucet is a faucet installed in the wall. When the faucet is installed, the main body of the faucet is not installed directly on the wall. Instead, the faucet body is first placed in a box, and then the box is buried in the wall. This installation method enables the box to effectively protect the faucet body. Therefore, the pre-embedded box actually refers to a box that is convenient for the faucet to be installed in the wall.

[0003] In order to facilitate the installation of the faucet body in the box body, the box body is divided into a box body and a box cover, and the box body and the box cover are fixed by screws to form a complete box body. Although this split box body can facilitate the disassembly and assembly of the faucet body, it cannot ensure that the wall surfaces of the box body and the box cover are in close contact with each other, and the sealing cannot be guaranteed. The connection position between the joint on the faucet body and the water pipe is in the box body. If a water leak occurs, the water flow will easily leak out of the box body through the gap between the box body and the box cover, and finally penetrate into the wall, causing water seepage in the wall. In order to facilitate the connection between the joint of the faucet body and the water pipe, a number of connecting holes corresponding to the joint positions of the faucet body are provided on the inner and outer walls of the faucet body, and the connecting holes are connected to the internal space of the box body. The water pipe penetrates into the box body through the connecting holes and is connected to the joint of the faucet body. Therefore, once the box body leaks, the water flow will easily leak out of the box body through the gap between the outer wall of the water pipe and the inner wall of the connecting hole, causing water seepage in the wall and affecting the life of the wall. Summary of the invention

[0004] The utility model aims to solve the existing technical problem and provide a high-sealing waterproof drainage pre-buried box body, which can effectively prevent water in the box body from leaking out of the box body, thereby preventing water seepage in the wall and ensuring the service life of the wall.

[0020] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0021] See also Figures 1 to 6, the present utility model provides a high-sealing waterproof and drainage embedded box body, which includes a box body 1, an opening 2 provided at the center of the front side of the box body 1, the opening 2 is in communication with the internal space of the box body 1, the front side side wall of the box body 1 is provided with a box cover 3 that fits thereto, the box cover 3 shields and seals the opening 2, and the outer edge of the box cover 3 is fixed to the box body 1 by a number of evenly distributed screws 4. The outer wall of the box body 1 is provided with a number of connection holes 5 that are in communication with its internal space. The rear side side wall of the box cover 3 is provided with a sealing edge 6 located inside the opening 2, and the sealing edge 6 is in an "O" shape. A sealing sleeve 7 sleeved outside the sealing edge 6 is provided between the outer wall of the sealing edge 6 and the inner wall of the opening 2, and the sealing sleeve 7 is made of rubber material. A sealing ring 8 that matches it is provided in the connection hole 5. An inner limiting portion 9 that fits the inner wall of the box body 1 is provided on the outer peripheral surface of the inner end of the sealing ring 8. An outer limiting portion 10 that fits the outer wall of the box body 1 is provided on the outer peripheral surface of the outer end of the sealing ring 8. A drainage structure that is in communication with the internal space of the box body 1 is provided on the lower side outer wall of the box body 1.

[0022] A number of sealing protrusions 11 that are evenly distributed axially are provided on the inner wall of the sealing ring 8, and the sealing protrusions 11 are in a ring shape. There is an annular water storage groove 12 between adjacent sealing protrusions 11.

[0023] The drainage structure includes a convex platform 13 provided in the middle of the lower side outer wall of the box body 1. A groove 14 corresponding to the position of the convex platform 13 is provided on the lower side inner wall of the box body 1. A through hole 15 that communicates with the groove 14 is provided at the center of the lower surface of the convex platform 13, and the diameter of the through hole 15 is smaller than the diameter of the groove 14. A water diversion plate 16 that matches it is provided in the groove 14. A drainage joint 17 in a tubular shape is provided at the center of the lower surface of the water diversion plate 16. A water diversion groove 18 that communicates with the drainage joint 17 is provided on the upper surface of the water diversion plate 16. The upper surface of the water diversion plate 16 is flush with or lower than the lower side inner wall of the box body 1. The lower end of the drainage joint 17 passes downward through the through hole 15, and an adapter joint 19 located below the convex platform 13 is externally screwed to the lower end of the drainage joint 17.

[0024] The diameter of the water diversion groove 18 gradually decreases from top to bottom.

[0025] A sealing gasket 20 made of rubber material is provided between the lower surface of the water diversion plate 16 and the bottom of the groove 14. The sealing gasket 20 is in a ring shape and is sleeved outside the drainage joint 17.

[0026] An auxiliary gasket 21 made of rubber material is provided between the lower surface of the convex platform 13 and the upper end surface of the adapter joint 19, and the auxiliary gasket 21 is sleeved outside the upper end of the adapter joint 19.

[0027] The usage method of the present utility model is as follows:

[0028] The presence of the sealing rib 6 can effectively increase the sealing area between the box cover 3 and the box body 1, thereby effectively improving the sealing effect, and the sealing sleeve 7 arranged between the inner wall of the opening 2 and the sealing rib 6 can be effectively filled in the gap between the inner wall of the opening 2 and the sealing rib 6 by deformation when the sealing rib 6 is squeezed into the opening 2, thereby further ensuring the sealing performance of the box cover 3 when covering the opening 2 on the box body 1. Therefore, when the water flow of the box body 1 attempts to leak to the outside through the gap between the rear side wall of the box cover 3 and the front side wall of the box body 1, it will be blocked by the sealing sleeve 7. At this moment, the sealing sleeve 7 can effectively prevent water leakage and prevent the water flow of the box body 1 from leaking to the outside through the gap between the rear side wall of the box cover 3 and the front side wall of the box body 1.

[0029] When the water pipe is inserted into the box body 1 through the connecting hole 5 to be connected with the faucet body, the water pipe actually passes through the inner hole of the sealing ring 8 to enter the box body 1. Therefore, when the water pipe is connected to the faucet body, the sealing ring 8 is in the gap between the outer wall of the water pipe and the inner wall of the connecting hole 5. The inner wall of the sealing ring 8 is tightly fitted with the outer wall of the water pipe, and the outer peripheral surface of the sealing ring 8 is tightly fitted with the inner wall of the connecting hole 5, thereby effectively ensuring the sealing between the outer wall of the water pipe and the inner wall of the connecting hole 5, and preventing the water flow in the box body 1 from leaking to the outside through the gap between the outer wall of the water pipe and the inner wall of the connecting hole 5.

[0030] The existence of the adapter joint 19 can be used to connect an external pipe, and the external pipe can be used for drainage, guiding the water flow to the actual drainage position instead of directly discharging it into the wall, effectively avoiding water seepage in the wall. When water leakage occurs in the box body, the water flow will fall to the lower inner wall of the box body under the influence of gravity, and the upper surface of the water guide plate 16 is flush with or lower than the lower inner wall of the box body 1. The water flow in the box body will directly flow into the water guide groove 18, and then flow into the adapter joint 19 through the drainage joint 17, and finally be discharged to the actual required drainage position through the pipe connected to the adapter joint 19.

[0031] In summary, the utility model can effectively improve the sealing performance when the box cover 3 covers and seals the opening 2 through the sealing sleeve 7, and can effectively ensure the sealing performance when the water pipe passes through the connecting hole 5 through the sealing ring 8, thereby effectively preventing the water flow in the box body from leaking to the outside of the box body through the gap between the rear side wall of the box cover 3 and the front side wall of the box body 1, and the gap between the outer wall of the water pipe and the inner wall of the connecting hole 5, causing water seepage in the wall, thereby achieving the effect of preventing water seepage, and can discharge the water flow in the box body to the outside of the wall through the drainage structure. This drainage method can not only prevent water seepage in the wall, but also effectively prevent the faucet body from being eroded by water accumulated in the box body, thereby effectively ensuring the life of the faucet body and the wall.

[0032] The inner wall of the sealing ring 8 is provided with a plurality of sealing protrusions 11 which are evenly distributed axially. The sealing protrusions 11 are annular, and an annular water storage groove 12 is provided between adjacent sealing protrusions 11. The existence of the sealing protrusions 11 can further improve the sealing effect of the sealing ring 8, and the existence of the water storage groove 12 can delay the time of water leakage, thereby improving the sealing effect of the sealing ring 8 in disguise. When the water flow in the box body leaks outward through the gap between the inner wall of the sealing ring 8 and the outer wall of the water pipe, the water flow will continue in the water storage groove 12, thereby effectively preventing the water flow from continuing to leak outward.

[0033] The diameter of the water diversion groove 18 gradually decreases from top to bottom. This structural design enables the water diversion groove 18 to quickly guide the water flow into the drainage joint 17 to ensure drainage efficiency.

[0034] A sealing gasket 20 is provided between the lower surface of the water guide plate 16 and the bottom of the groove 14. The sealing gasket 20 is made of rubber and is annular. The sealing gasket 20 is sleeved on the outside of the drainage joint 17. The presence of the sealing gasket 20 can effectively ensure the sealing between the lower surface of the water guide plate 16 and the bottom of the groove 14, thereby preventing the water flow in the box from leaking outward through the gap between the lower surface of the water guide plate 16 and the bottom of the groove 14.

[0035] A set of auxiliary gaskets 21 are provided between the lower surface of the boss 13 and the upper end surface of the adapter joint 19. The auxiliary gasket 21 is made of rubber. The adapter joint 19 can effectively fix the position of the drain joint 17 by pressing the auxiliary gasket 21 tightly against the lower surface of the boss 13. The existence of the auxiliary gasket 21 can not only effectively ensure the sealing between the lower surface of the boss 13 and the upper end surface of the adapter joint 19, but also prevent the water in the box from leaking out through the gap between the outer wall of the drain joint 17 and the inner wall of the perforation 15, and can also play an anti-wear effect, avoiding the situation where the lower surface of the boss 13 and the upper end surface of the adapter joint 19 are frequently in contact with each other and cause wear.
