A magnetic fixing structure

Abstract

This invention provides a magnetic fixing structure, including a fixing base, a hanging component, and a docking assembly. The docking assembly includes a first magnetic component, a second magnetic component, a first support component, and a second support component. The first support component is installed on the hanging component and has an insertion protrusion. The second support component is installed on the fixing base and has a docking groove with elastic peripheral walls. The second magnetic component is positioned near the bottom of the groove. When suspended, the insertion protrusion is inserted into the docking groove, and the peripheral walls of the docking groove expand and then retract to form a close-fitting clamp. Simultaneously, the two magnetic components magnetically attract each other, achieving dual fixing through "magnetic force + elastic clamping," significantly enhancing the stability of the attraction, providing reliable connection, convenient placement and removal, and a long service life.

Description

Technical Field

[0001] This invention relates to the field of hanging structure technology, and in particular to a magnetic fixing structure. Background Technology

[0002] Typically, handheld hanging devices (such as razors, cleaning tools, hair dryers, shower heads, and even some tools used in workshops) are used. When not in use, they can be hung on a fixed base on a wall or stand to avoid loss and space occupation. Currently, structures that use magnetic adsorption to fix the hanging devices to the base have appeared on the market. This structure usually uses magnets on both the hanging device and the base to achieve magnetic attraction and fixation, making it convenient for users to pick up and put away with one hand.

[0003] However, existing magnetic mounting structures have some shortcomings. They typically rely solely on the interaction of two magnets—either a flat surface or a simple uneven surface—for attraction, resulting in limited magnetic force. During use, when the item is subjected to slight external force (such as pulling or accidental impact) or when the magnetic force weakens after prolonged use, the item can easily detach from the mounting, causing damage or impact noise, thus affecting the user experience. Therefore, a magnetic mounting structure with stronger attraction and more reliable fixation is needed. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention proposes a magnetic fixing structure with strong adsorption force, stable connection, and convenient placement and removal, thereby solving the problems of insufficient adsorption force and easy detachment of existing magnetic field fixing seats.

[0005] A magnetic fixing structure includes a fixing base, a hanging component, and a docking assembly, wherein, The docking assembly includes a first magnetic component, a second magnetic component, a first support component, and a second support component.

[0006] The first support member is mounted on the suspension mounting base of the hanger and is provided with a plug-in protrusion. The first magnetic member is installed inside the plug-in protrusion. The second support member is mounted on the fixed base and is provided with a mating groove. The peripheral wall of the mating groove is elastic. The second magnetic member is installed inside the second support member and is positioned near the bottom of the mating groove.

[0007] The pendant is suspended on the fixed base by the docking assembly. The plug-in protrusion is inserted into the docking groove. The docking groove forms a close-fitting clamping state for the plug-in protrusion through elastic expansion and contraction. The first magnetic component and the second magnetic component are attracted to each other by magnetic force.

[0008] The magnetic fixing structure provided by this invention achieves dual fixing through "magnetic force + elastic clamping", which significantly enhances the adsorption stability and has the advantages of reliable connection, convenient loading and unloading, and long service life.

[0009] Furthermore, the peripheral wall of the docking groove is spherical, while the bottom of the groove is flat. The outline of the insertion protrusion is the same as that of the mounting groove, and its end is also flat. When the hanger is suspended, the insertion protrusion is enclosed within the docking groove, and both the end face and peripheral face of the insertion protrusion are in contact with the bottom and peripheral wall of the docking groove. This not only ensures a tight fit and secure clamping but also allows the hanger to rotate. The hanger is installed by rotating around the central axis of the docking groove.

[0010] Furthermore, both the docking groove and the insertion protrusion are spherical, and the hanger is installed by swinging at any angle through the ball head structure between the docking groove and the insertion protrusion; the first magnetic component is spherical and installed at the end of the insertion protrusion, and the second magnetic component is installed at the bottom of the docking groove. The side of the second magnetic component facing the opening of the docking groove is an arc surface. When the hanger is swinging, the first magnetic component is in contact with the arc surface of the second magnetic component, or the side of the second magnetic component facing the opening of the docking groove is a flat surface, and when the insertion protrusion and the second magnetic component are coaxial or parallel, the flat surface of the first magnetic component is in contact with the second magnetic component.

[0011] Furthermore, the peripheral wall of the docking groove is composed of at least two barriers, which are elastic and expand first and then contract during the insertion or withdrawal of the insertion protrusion. The structure is simple and easy to form.

[0012] Furthermore, to avoid excessive impact force during docking, the docking assembly also includes a buffer pad, which is installed on the fixed base or the hanging component, and in the suspended state, the buffer pad is clamped between the fixed base and the hanging component.

[0013] Preferably, the buffer pad is annular and is fitted around the outer periphery of the docking groove to further enhance the elasticity of the docking groove. At the same time, it can prevent the enclosure of the docking groove from expanding excessively and being damaged.

[0014] Furthermore, the magnetic fixing structure also includes a swing assembly, through which the second support member is swing-mounted on the fixed base.

[0015] Preferably, the swing assembly includes a swing ball head, a swing body, and a swing limiting ring. The swing ball head is locked into a pre-reserved mounting hole on the fixed base by screws. One end of the swing body is swing-mounted to the swing ball head. The swing limiting ring is installed in the mounting hole and sleeved around the swing docking part of the swing ball head and the swing body to limit the swing angle of the swing body. The second support member is installed at the outward-facing end of the swing body. That is, after the hanger is suspended, it has the flexibility to swing and rotate.

[0016] Furthermore, to prevent damage to the magnetic components, both the first and second magnetic components include a magnetic core, a protective cover, and a soft pad. The magnetic core is installed inside the protective cover and is sealed by the soft pad.

[0017] Furthermore, the hanging end of the pendant is provided with a hanging mounting seat on its back, and the first support member is mounted on the hanging mounting seat.

[0018] Furthermore, the hanging device is a shower head, the fixing base is a shower head seat, or the fixing base is a shower head seat with water outlet function, which is provided with an inlet channel, an outlet channel, an installation cavity and a switching valve. There are at least two outlet channels, and both of them are connected to the inlet channel through the installation cavity. The switching valve is installed in the installation cavity to switch the connection between any outlet channel and the inlet channel.

[0019] The water outlet end of the water outlet channel forms a water outlet connector around the periphery of the fixed base.

[0020] As can be seen from the above description of the present invention, the present invention has the following beneficial effects: Strong adsorption and stable connection: By embedding the magnetic component in the pluggable protrusion and elastic groove structure, a dual fixation of magnetic adsorption and mechanical engagement is achieved. In addition, the tight fit between the pluggable protrusion and the elastic groove greatly increases the contact area and friction. Together with the magnetic force, it forms a double insurance of "magnetic force + elastic clamping", which significantly improves the stability of the suspension and effectively prevents accidental drop due to external force or weakening of magnetic force. Adaptive and buffer protection: The elastic peripheral wall of the docking groove can adapt to the insertion of the plug protrusion and provide continuous elastic clamping force during clamping. It has a certain tolerance for manufacturing tolerances and slight misalignment. In addition, the addition of the buffer pad further absorbs the impact force when hanging the hanger, reduces collision noise, protects the elastic enclosure, and extends its service life. Adjustable angle and easy to use: By adding a swing component or directly equipping the docking component with a ball head swing mechanism, the hanging part can swing freely within a certain angle and the angle can be flexibly adjusted.

[0023] To make the technical problems, technical solutions, and beneficial effects of this invention clearer and more understandable, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0024] Please see Figures 1 to 15 A magnetic fixing structure mainly includes a fixing base 1, a hanging part 2 and a docking component 3.

[0025] The fixing base 1 is used to fix it to the wall or bracket, and it is provided with the installation interface of the docking component 3. The hanging end of the hanging piece 2 is provided with a hanging mounting base 21 for installing another part of the docking component 3.

[0026] Optionally, the hanging part 2 can be a razor, cleaning tool, hair dryer, shower head, or even some tools in a processing workshop (clamps, pliers, wrenches, etc.).

[0027] For example, in one specific embodiment, the hanging accessory 2 is a shower head, and the fixing base 1 itself is a shower head base with multiple water outlet functions, which internally has a water inlet channel 11, at least two water outlet channels 12, a mounting cavity 13, and a switching valve 14. Each of the water outlet channels 12 is connected to the water inlet channel 11 through the mounting cavity 13, and the switching valve 14 is installed in the mounting cavity 13 to switch the connection between the water inlet channel 11 and any one of the water outlet channels 12. The water outlet end of each water outlet channel 12 forms a water outlet connector 15 on the periphery of the fixing base 1, which can be connected to a top spray, handheld accessory, or other water outlet device.

[0028] The docking assembly 3 is the component that enables the suspension of the hanging part 2, and includes a first magnetic component 31, a second magnetic component 32, a first support component 33, and a second support component 34, wherein... The first support member 33 is fixedly installed on the suspension mounting base 21 of the hanger 2, and has a plug-in protrusion 331 on the side facing the fixed base 1. The first magnetic member 31 is embedded and fixed inside the plug-in protrusion 331.

[0029] The second support member 34 is mounted on the fixed base 1. The second support member 34 has a docking groove 341. Preferably, the peripheral wall of the docking groove 341 is spherical and has a flat bottom. The outer contour of the insertion protrusion 331 preferably matches the inner contour of the docking groove 341. After the hanging member 2 is suspended, the hanging member 2 can rotate around the central axis of the docking groove 341.

[0030] The peripheral wall of the docking groove 341 is elastic. Specifically, it can be formed by two or more elastic barriers 341a, with elastic gaps between each barrier 341a. The second magnetic element 32 is installed inside the second support member 34 and is disposed adjacent to the bottom of the docking groove 341.

[0031] When the pendant 2 needs to be suspended, the user aligns the insertion protrusion 331 on the back of the pendant 2 with the mating groove 341 on the fixing base 1 and pushes it in. During insertion, the end of the insertion protrusion 331 abuts against and expands the periphery of the mating groove 341 formed by the elastic retainer 341a, causing it to expand elastically. When the insertion protrusion 331 is fully inserted until its end face contacts the bottom of the mating groove 341, the first magnetic element 31 and the second magnetic element 32 approach each other, and the strong magnetic force causes them to quickly attract each other together. At the same time, the elastic retainer 341a retracts under its own elastic force, tightly fitting and wrapping around the periphery of the insertion protrusion 331, forming a "wrapping" mechanical clamping state. This dual effect of "magnetic attraction" and "elastic clamping" makes the pendant 2 very securely suspended on the fixing base 1, greatly enhancing its resistance to falling off.

[0032] To further enhance stability and protection, the docking assembly 3 also includes an annular buffer pad 35, which can be made of elastic materials such as rubber or silicone and is fitted around the outer periphery of the docking groove 341. When the hanger 2 is suspended in place, the hanging mounting base 21 or the flat surface on the back of the hanging end of the hanger 2 will press against this buffer pad 35. The buffer pad 35 serves multiple functions: first, it acts as a final limit to prevent the hanger 2 from being over-inserted; second, through its own elastic deformation, it absorbs the impact force when the hanger 2 is hung, reducing noise; and third, its annular structure provides external support for the internal elastic barrier 341a, preventing the barrier 341a from excessively expanding and deforming or being damaged during insertion and removal.

[0033] To facilitate user access, this embodiment adds a swing assembly 4 between the fixed base 1 and the second support member 34. The swing assembly 4 includes a swing ball head 41, a swing body 42, and a swing limiting ring 43. The swing ball head 41 is locked into a pre-reserved mounting opening on the fixed base 1 by screws. One end of the swing body 42 forms a ball joint with the swing ball head 41, allowing the swing body 42 to swing in multiple directions relative to the fixed base 1 within a certain angle. The swing limiting ring 43 is installed in the mounting opening and fits around the outer periphery of the ball joint, its inner diameter limiting the maximum swing angle of the swing body 42 to prevent excessive swinging. The second support member 34 is fixedly installed on the outward-facing end of the swing body 42. At this time, the second support member 34, which carries the docking groove 341, has the ability to swing flexibly.

[0034] Alternatively, in another embodiment, a ball-head docking structure can be directly formed between the first support member 33 and the second support member 34. Specifically, both the docking groove 341 and the insertion protrusion 331 are spherical, and the hanger 2 is installed by swinging at any angle through the ball-head structure between the docking groove 341 and the insertion protrusion 331. In this embodiment, the first magnetic member 31 is spherical and installed at the end of the insertion protrusion 331, and the second magnetic member 32 is installed at the bottom of the docking groove 341. The side of the second magnetic member 32 facing the opening of the docking groove 341 is an arc surface. When the hanger 2 is swinging, the first magnetic member 31 is in contact with the arc surface of the second magnetic member 32. Or, in another embodiment, the side of the second magnetic member 32 facing the opening of the docking groove 341 is a flat surface, and when the insertion protrusion 331 and the second magnetic member 32 are coaxial or parallel, the first magnetic member 31 is in contact with the flat surface of the second magnetic member 32.

[0035] To protect the magnetic components and extend their service life, both the first magnetic component 31 and the second magnetic component 32 include a magnetic core, a protective cover, and a soft pad. The magnetic core is installed inside the protective cover, which is then sealed by the soft pad within a metal or plastic protective cover 5. The open end of the protective cover 5 is sealed with a soft pad 6 that has a certain elasticity and sealing properties. The soft pad 6 not only prevents moisture and impurities from directly contacting the magnet, avoiding corrosion, but also ensures, due to its flexibility, that the end face of the insertion protrusion 331 and the bottom of the mating groove 341 can fit tightly together without affecting the transmission of magnetic force.

[0036] This invention creatively combines magnetic adsorption with elastic mechanical clamping through the above structure, and supplements it with buffering, swing adjustment and sealing protection, to provide a magnetic fixing structure with adsorption force far exceeding that of traditional designs. It is stable, reliable and user-friendly, and effectively solves the core problem of insufficient adsorption force of existing magnetic field fixing seats.
