Description

Technical Field

[0001] This utility model relates to the technical field of bathtub accessories, and in particular to a multi-directional adjustable base. Background Technology

[0002] In bathtub systems, to achieve "omnidirectional and concealed" installation of accessories such as waterfall spray, colored lights, sound systems, and massage nozzles, as well as support for the overall bathtub base, a ball-head-ball-nest structure omnidirectional base is commonly used. Designers hope that the showerhead or light head can be bent to any angle by hand and remain smooth, leak-proof, and rust-free in environments with long-term immersion in water, foaming agents, and high temperature and humidity. However, traditional bathroom omnidirectional brackets directly adopt industrial ball joint solutions, which expose the following typical pain points in the special microenvironment of a bathtub, characterized by "long-term immersion in water + temperature difference circulation + chemical corrosion".

[0003] The gap between the ball head and the socket is originally at the micrometer level. When the hot water cools down or the bathtub is drained, the air inside the cavity contracts to form a negative pressure, which draws the residual water containing shower gel and disinfectant into the socket. When the temperature is raised again, the internal expansion "pumps" the sewage out, forming visible yellow rust or white soap scum. A customer complained, "My bathtub, which I just bought two months ago, has a ring of mold around the base of the shower head."

[0004] To prevent the shower head from being pulled out, existing designs often have a flexible retaining ring at the nozzle opening. This retaining ring groove is located on a visible surface, which not only affects the minimalist appearance but, more importantly, requires maintenance personnel to crawl entirely into the tub and use specialized pliers to remove the retaining ring if the bathtub is already sealed with sealant. This can easily result in repair costs of several thousand yuan.

[0005] When the base is fixed to the mounting surface with countersunk bolts, the bolt heads sink into the ball socket base plate, occupying the space that could have been used to arrange the O-rings. If the sealing ring is moved to the outside of the bolt, the sealing diameter increases, the compression is difficult to control, and the function of the shock-absorbing pad cannot be taken into account. As a result, the sealing and shock absorption must be designed separately, increasing the number of parts. Utility Model Content

[0006] Purpose of the invention: The purpose of this utility model is to provide a multi-directional adjustable base to solve the problems of intermittent drainage / venting, complex assembly, and conflict between sealing and shock absorption in existing bases.

[0007] Technical solution:

[0008] A multi-directional adjustable base includes a mounting base and a connecting column. The mounting base is provided with a ball socket, and an omnidirectional ball is connected to the end of the connecting column. The omnidirectional ball is embedded in the ball socket, and the connecting column extends out of the ball socket.

[0009] The mounting base has a through cross hole at the bottom of the ball socket, and the universal ball has an air groove corresponding to the position of the cross hole, with the opening of the air groove always facing the cross hole.

[0010] Preferably, the opening of the ball socket is chamfered.

[0011] In this embodiment, the universal ball can slide in along the chamfer during assembly without the need for special pressing tools, thus avoiding chipping at the aluminum alloy ball socket opening; at the same time, the chamfer removes sharp edges, so users will not cut their fingers when adjusting the shower head by hand, improving the safety of using the bathtub.

[0012] Preferably, the mounting base has a retaining ring embedded in the ball socket, and the retaining ring is located on one side of the chamfer.

[0013] Preferably, the connecting post has a threaded hole along its axial direction.

[0014] Preferably, the side wall of the connecting column is provided with a plurality of positioning grooves, which extend along the axial direction of the connecting column.

[0015] In this embodiment, the additional accessories can be screwed in by hand, and no additional adapters are required for on-site installation; the bottom of the threaded hole is connected to the ball head body to form a rigid load-bearing path, avoiding the problem of breakage at the root of the plastic nozzle thread.

[0016] Preferably, the bottom surface of the mounting base has a groove around the periphery of the cross hole.

[0017] In this embodiment, an O-ring or silicone shock-absorbing pad can be embedded in the groove to form the "first waterproof wall," preventing water seepage from the bathtub wall into the wooden joists. The groove is a recessed design, so the O-ring does not take up installation height after compression, ensuring zero step difference between the base and the tile surface, and preventing dirt and grime from accumulating.

[0018] Preferably, the mounting base has several fixing holes on its side wall, and the fixing holes are arranged through the mounting base along its axial direction.

[0019] Preferably, the mounting base is a frustum.

[0020] Beneficial effects: The through-type breathing structure of "cross-shaped through hole + blind air groove" achieves real-time balance of air pressure inside and outside the ball socket and zero backflow of bath water;

[0021] The ball socket opening is chamfered and the elastic retaining ring is fitted together to achieve the effect of locking the omnidirectional ball after pressing it in 3 seconds and quick disassembly by hand without tools.

[0022] The structure, which utilizes the recessed grooves around the cross-shaped hole and the stepped fixing holes arranged in layers, ensures that the sealing ring and the countersunk bolt do not interfere with each other. Attached Figure Description

[0027] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] like Figure 1-3 As shown, a multi-directional adjustable base includes a mounting base 1 and a connecting column 2. The mounting base 1 is frustum-shaped, with a recessed ball socket 11 at the center of its large end. A universal ball 21 is embedded in the ball socket 11. The universal ball 21 is detachable from the ball socket 11. The universal ball 21 is connected to the end of the connecting column 2 to form a structure that can rotate in all directions.

[0030] Mounting base 1 has a through cross hole 12 at the bottom of ball socket 11 for ventilation or drainage. The lower surface of universal ball 21 has an air groove 22 corresponding to the position of cross hole 12. The air groove 22 is a blind hole, and its opening always faces the cross hole 12 to ensure that the air groove 22 and the cross hole 12 remain connected during the rotation of universal ball 21, so as to avoid increased rotational resistance or sealing failure due to changes in air pressure.

[0031] Preferably, the universal ball 21 and the ball socket 11 are in clearance fit, with the clearance controlled between 0.02mm and 0.1mm, which can ensure flexible rotation and avoid excessive wobbling.

[0032] The opening of the ball socket 11 is chamfered 13 to facilitate the assembly of the universal ball 21 and reduce edge stress concentration. To prevent the universal ball 21 from coming out, the mounting base 1 has a retaining ring 3 embedded in the ball socket 11. The retaining ring 3 is located on one side of the chamfer 13. The retaining ring 3 is an elastic open ring with an inner diameter slightly smaller than the ball diameter of the universal ball 21. During assembly, it is elastically deformed and locked into the ball socket 11 to play a limiting role.

[0033] The connecting column 2 is provided with a threaded hole 23 along its axial direction for threaded connection with external equipment. The opening of the threaded hole 23 faces away from the base 1. The side wall of the connecting column 2 is provided with a number of positioning grooves 24. The positioning grooves 24 extend along the axial direction and are evenly distributed on the outer circumferential surface of the connecting column 2 for circumferential positioning with the external structure to prevent relative rotation. In this embodiment, there are three positioning grooves 24.

[0034] The bottom surface of the mounting base 1 has a groove 14 around the cross hole 12. The groove 14 is a recessed groove that can be used to install a sealing ring or a buffer pad to improve the sealing or shock absorption performance between the base and the mounting surface.

[0035] The mounting base 1 has several fixing holes 15 on its side wall. The fixing holes 15 penetrate the mounting base 1 along the axial direction and are used to fix the mounting base 1 to the external structure by bolts. In this application, there are three fixing holes 15. The fixing holes 15 are stepped holes. One end near the bottom surface is provided with a countersunk structure to accommodate the bolt head and avoid the bolt protruding and affecting the flatness of the installation.

[0036] Furthermore, the groove 14 is an arc-shaped recessed groove, and there are several grooves 14. The grooves 14 are spaced apart from the fixing holes 15, and the bolts in the fixing holes 15 further provide sealing.

[0037] In this embodiment, both the mounting base 1 and the connecting column 2 are made of aluminum alloy or resin material. The surface is anodized to improve corrosion resistance and surface hardness. The universal ball 21 and the connecting column 2 can be an integral structure or a separate structure, assembled by threaded connection, which is convenient for processing and maintenance.

[0038] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
