Description

Technical Field

[0001] The utility model relates to a sealing member and an installation structure thereof, in particular to a sealing member with multiple waterproof functions and an installation structure thereof. Background Art

[0002] The outlet valve in a water supply system, such as a washbasin faucet or a kitchen faucet, etc., is usually installed on the countertop of a bathroom cabinet. During daily use, residual water will be left on the countertop after using the outlet valve. This residual water will gather towards the bottom of the outlet valve, that is, at the joint between the outlet valve and the countertop. Since the installation of the outlet valve on the countertop is a single-sided force installation relying on only one installation stud, and then the bottom surface of the outlet valve presses a sealing gasket to form an installation seal. The single-sided force installation is likely to cause uneven stress on the bottom surface of the outlet valve. As a result, the sealing gasket cannot be evenly pressed by the bottom surface of the outlet valve on the countertop, which makes the sealing gasket unable to effectively seal the joint between the outlet valve and the countertop. Therefore, the residual water often leaks from this joint, affecting the use of the bathroom cabinet. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a sealing member with multiple waterproof functions and an installation structure thereof for an outlet valve installed on a countertop with single-sided force.

[0004] The technical problem of the utility model is realized through the following technical solutions:

[0005] A sealing member with multiple waterproof functions includes a body. A plurality of sealing ring sheets arranged vertically are provided on the outer circumferential surface of the body, and a supporting pad is provided above the plurality of sealing ring sheets. A sealing convex ring is provided on the supporting pad. An inner ring sheet is reserved between the sealing convex ring and the inner edge of the supporting pad, and an outer ring sheet is reserved between the sealing convex ring and the outer edge of the supporting pad.

[0006] Each of the sealing ring sheets is an elastic thin sheet circumferentially surrounding the outer circumferential surface of the body.

[0007] The lower surface of the outer edge of each of the sealing ring sheets is provided with a sealing inclined surface.

[0008] The supporting pad is formed by turning up and circumferentially surrounding from the top of the body.

[0009] The body, the sealing ring sheets, the supporting pad, the sealing convex ring, the inner ring sheet and the outer ring sheet are all of an integrally formed structure.

[0010] The body is a cylindrical tube with a middle hole inside.

[0011] A sealing element installation structure with multiple waterproof functions. The sealing element is used for the installation and sealing of a water outlet valve on a tabletop. There is a through installation hole on the tabletop. The main body is fitted in the installation hole, and multiple seals are formed by several sealing ring pieces contacting the hole wall of the installation hole. The cushion is exposed from the top of the installation hole and fits on the tabletop. The water outlet valve presses the cushion and is installed on the tabletop, and the installation seal between the water outlet valve and the tabletop is formed by the cushion.

[0012] A sealing ring groove is provided on the bottom surface of the water outlet valve. The water outlet valve presses the cushion and is installed on the tabletop, and the sealing convex ring is fitted into the sealing ring groove.

[0013] The bottom surface of the water outlet valve presses the inner ring piece and the outer ring piece at the same time, and then an installation seal is formed between the bottom surface of the water outlet valve and the tabletop.

[0014] An installation stud is provided in the water outlet valve. The installation stud passes downward through the middle hole of the main body and the installation hole on the tabletop to form a locking connection.

[0015] Compared with the prior art, the present utility model mainly provides a sealing element with a novel structure. There are several sealing ring pieces arranged vertically on the outer circumferential surface of the main body of the sealing element and a cushion arranged above the several sealing ring pieces. The top surface of the cushion is provided with a sealing convex ring, and an inner ring piece is reserved between the sealing convex ring and the inner edge of the cushion, and an outer ring piece is reserved between the sealing convex ring and the outer edge of the cushion. In this way, only by fitting the main body in the installation hole on the tabletop and then contacting the several sealing ring pieces with the hole wall of the installation hole, multiple seals can be formed. At the same time, the cushion is exposed from the top of the installation hole and fits on the tabletop, and the water outlet valve only needs to press the cushion and be installed on the tabletop. Specifically, the water outlet valve forms a fitting installation with the sealing convex ring through the sealing ring groove on the bottom surface, and the bottom surface of the water outlet valve presses the inner ring piece and the outer ring piece at the same time. At this time, the installation seal between the water outlet valve and the tabletop is formed by the cushion. Obviously, this first waterproof structure formed by pressing the bottom surface of the water outlet valve in cooperation with the cushion, the sealing convex ring, the inner ring piece and the outer ring piece, combined with the second waterproof structure formed by the several sealing ring pieces contacting in the installation hole, enables the water outlet valve to have multiple waterproof functions even when it is installed on the tabletop by a single installation stud with unilateral force, thereby improving the sealing performance and multiple waterproof and leak-proof functions of the joint between the bottom surface of the water outlet valve and the tabletop, and effectively preventing the residual water on the tabletop from leaking from this joint and affecting the use of the bathroom cabinet.

[0021] The embodiments of the present invention will be further described in detail below with reference to the above drawings.

[0022] As Figures 1 to 5 shown, 1. Body, 2. Sealing ring piece, 21. Sealing inclined surface, 3. Support pad, 31. Sealing convex ring, 32. Inner ring piece, 33. Outer ring piece, 4. Middle hole, 5. Water outlet valve, 51. Sealing ring groove, 52. Stud hole, 6. Tabletop, 61. Installation hole, 7. Installation stud, 8. Nut, 9. Double gasket.

[0023] A seal with multiple waterproof functions and its installation structure, as Figure 3 shown, is mainly applicable to the water outlet valve 5 in the water supply system, such as the sealing installation of a washbasin faucet or a kitchen faucet on the tabletop 6 of a bathroom cabinet.

[0024] Among them, the seal includes a body 1 made of a soft material such as silica gel or rubber. The body is a cylindrical structure with a middle hole 4 inside, that is, the middle hole 4 penetrates axially along the body 1. A number of sealing ring pieces 2 arranged vertically and a support pad 3 arranged above the number of sealing ring pieces 2 are provided on the outer circumferential surface of the body 1. In fact, the more the number of sealing ring pieces, the more the number of waterproof layers. However, in this embodiment, as Figure 1 shown, only two sealing ring pieces 2 need to be provided to meet better waterproof requirements. The outer diameter dimensions of the two sealing ring pieces are exactly the same. Each sealing ring piece 2 is an elastic thin sheet circumferentially surrounding the outer circumferential surface of the body. And a sealing inclined surface 21 is provided on the lower surface of the outer edge of each sealing ring piece 2. Since the sealing ring piece 2 in this embodiment is a circular sheet following the shape of the body 1, the sealing inclined surface 21 on the lower surface of the outer edge of each sealing ring piece 2 exactly forms a conical surface.

[0025] The support pad 3 is formed by turning outwards from the top of the body 1 and circumferentially surrounding it. The support pad is a circular gasket. A circular sealing convex ring 31 is provided on the top surface of the support pad, and an inner ring piece 32 is reserved between the sealing convex ring and the inner edge of the support pad, and an outer ring piece 33 is reserved between the sealing convex ring and the outer edge of the support pad.

[0026] At the same time, the body 1, the two sealing ring pieces 2, the support pad 3, the sealing convex ring 31, the inner ring piece 32 and the outer ring piece 33 are all integrally formed structures.

[0027] The described seal is used for the installation and sealing of the water outlet valve 5 on the tabletop 6, and a through circular installation hole 61 needs to be preset on this tabletop; in this way, the body 1 of the seal can be directly fitted into the installation hole 61, and two seal ring pieces 2 contact the hole wall of the installation hole 61 to form multiple seals; of course, the outer diameter dimension of the two seal ring pieces 2 needs to be slightly larger than the aperture of the installation hole 61 to ensure that there is a certain pressing amount between the two seal ring pieces 2 and the installation hole 61, so that each seal ring piece 2 can closely fit against the hole wall of the installation hole 61 through the sealing inclined surface 21.

[0028] The described cushion 3 is exposed from the top of the installation hole 61 and fits on the tabletop 6, then the water outlet valve 5 only needs to be pressed against the cushion 3 and installed on the tabletop 6. Specifically, the water outlet valve 5 forms a matching fit with the sealing convex ring 31 through the sealing ring groove 51 on the bottom surface, and the bottom surface of the water outlet valve 5 simultaneously presses against the inner ring piece 32 and the outer ring piece 33. At this time, the cushion 3 can constitute the installation seal between the water outlet valve 5 and the tabletop 6.

[0029] In addition, the matching fit between the sealing convex ring 31 and the sealing ring groove 51 can also limit the position movement of the seal in the horizontal direction after being installed in place.

[0030] Then, an installation stud 7 is provided in the water outlet valve 5 through the stud hole 52 provided on one side. After the installation stud passes downward through the middle hole 4 in the body 1 and the installation hole 61 on the tabletop 6, it is threadedly locked and connected by a nut 8 at the bottom of the tabletop, and a double-layer gasket 9 can be provided between the nut 8 and the tabletop 6 to assist in locking. The double-layer gasket 9 is a horseshoe gasket and a horseshoe steel gasket.

[0031] Obviously, this first waterproof structure formed by pressing the bottom surface of the water outlet valve 5 in a common cooperation of the cushion 3, the sealing convex ring 31, the inner ring piece 32 and the outer ring piece 33, combined with the second waterproof structure formed by the contact of several seal ring pieces 2 in the installation hole 61, enables the water outlet valve 5 to have multiple waterproof functions even when it is installed on the tabletop 6 by only one installation stud 7 with unilateral force. Thus, it improves the sealing performance and multiple waterproof and leak-proof functions of the joint between the bottom surface of the water outlet valve 5 and the tabletop 6, effectively preventing the residual water on the tabletop 6 from leaking through this joint and affecting the use of the bathroom cabinet, and ensuring the user's water use experience and the cleaning requirements of the tabletop.

[0032] The above description is only a specific embodiment of the present invention. Those skilled in the art should understand that any structural design equivalent to this embodiment should be included within the protection scope of the present invention.
