Description

Technical Field

[0001] The present invention relates to an installation and fixing device for a curtain track, and particularly to a magnetic curtain track fixing hook. Background Art

[0002] As Figures 1 to 3 Shown is a commonly available magnetic curtain track fixing hook on the market currently. Its structure includes: an adsorption base 1, which is generally a cuboid, having a top surface 2, a bottom surface 3, and side edges 4 connecting the top surface and the bottom surface. A plurality of magnets are provided inside the adsorption base 1, and a plurality of magnetic conduction sheets 5 are provided on both sides and gaps of the magnet group formed by the plurality of magnets. A coupling portion 6 is provided on the top surface 2 of the adsorption base, and a track clamping seat 7 is provided at the coupling portion 6 for clamping the curtain track thereon. When this magnetic curtain track fixing hook is in use, its bottom surface 3 is adsorbed on a ferromagnetic metal plane capable of sensing magnetism to be installed, such as a window frame or a door panel, and then the curtain track is clamped on the track clamping seat 7.

[0003] Although this structure is very convenient for installation and use, it is not easy to disassemble. The main reason is that when the adsorption base 1 is adsorbed on a ferromagnetic metal plane capable of sensing magnetism, the bottom surface 3 of the adsorption base will completely adhere to the plane. In addition, in order to prevent the curtain track from falling, the magnetic force F of the generally used magnets is relatively strong. In this case, we define the suction force of the magnets and the magnetic conduction sheets on the ferromagnetic metal plane as F1 + F2 + F3 + F4. At the same time, the side edges 4 of the adsorption base are all vertical wall surfaces. Taking Figure 2 the direction as an example for explanation, when the user disassembles the adsorption base 1, there is no force application point on the adsorption base and it is not easy to grasp. Coupled with the strong magnetic suction force of the bottom surface 3, so as shown in Figure 2 the lower left corner, the adsorption base is removed by flipping in the way with a fulcrum O. A simple explanation and estimation are made for the resistance moment L2 of the existing product. Assuming the distance between each magnetic conduction sheet is D, the magnetic suction force formed by the bottom surface of the adsorption base is roughly estimated as D*F1 + 2D*F2 + 3D*F3 + 4D*F4 = L2 from left to right with the fulcrum O. And the force application moment L1 for the user to apply force to flip and remove the adsorption base must be greater than the resistance moment L2 formed by the bottom surface. Therefore, unless a tool is used, it is not easy to remove the adsorption base. Summary of the Invention

[0004] In view of the above problems, the present invention discloses a magnetic curtain track fixing hook, aiming to provide a magnetic curtain track fixing hook with a simple structure, convenient, labor-saving disassembly and assembly.

[0005] The specific technical solutions are as follows:

Detailed implementation manners

[0026] To make the technical solution of the present invention clearer and more definite, the present invention will be further described below with reference to the accompanying drawings. Any solution obtained by equivalent replacement of the technical features of the technical solution of the present invention and through conventional reasoning falls within the protection scope of the present invention.

[0027] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0028] Please refer to the attached Figures 4 to 8 As shown, this embodiment provides a magnetic curtain track fixing hook, which includes: an adsorption seat 10, the adsorption seat has a top surface 11, a bottom surface 12 and a side 13 connecting the top surface and the bottom surface. The top surface 11 is provided with a joint 14, and the joint 14 is provided with a track clamping seat 15, and the track clamping seat can be used for clamping the curtain track. A plurality of magnets and iron sheets 16 are arranged in the adsorption seat 10, and the iron sheets 16 are exposed on the surface of the bottom surface 12. In this embodiment, the adsorption seat 10 is a rectangular body, so it has two long sides 131 and two short sides 132, but it is not limited thereto. The adsorption seat can also be in other forms such as a cylinder, a hexagonal prism or a triangular prism, etc., and the distance between the outermost iron sheet and the long side is less than or equal to the distance that the iron sheet protrudes from the bottom surface.

[0029] The bottom surface 12 of the adsorption seat is provided with at least one gradually expanding inclined side wall 17 towards the top surface 11, so that the width of the adsorption seat 10 in an axial direction gradually expands from the bottom surface 12 towards the top surface 11, so that the width of the adsorption seat 10 in this axial direction gradually increases and becomes wider from the bottom surface 12 towards the top surface ********** Figure 8 Taking the schematic direction of Figure 8 as an example for further explanation, at both ends of the bottom surface in the short axis direction, that is, on the two long side edges 131 of the bottom surface 12, an inclined side wall 17 is provided and extends towards the top surface 11. Therefore, the bottom surface 12 has a width, and the width will increase as the two inclined side walls 17 gradually expand outwards. The width of the bottom surface 12 is preferably less than or equal to the width of the track clamping seat 15 in the same axial direction.

[0030] In this embodiment, the bottom surface of the adsorption seat is provided with an inclined side wall 17 on both the two long side edges 131 and the two short side edges 132, and gradually expands towards the top surface 11. However, this is not a limitation. It is also possible to only provide inclined side walls 17 on the two long side edges 131 and gradually expand towards the top surface 11, while not providing inclined side walls on the two short side edges 132. However, when the adsorption seat 10 is a cylinder, the inclined side wall 17 will become an annular inclined side wall. The inclined side wall 17 can extend from the bottom surface 12 to the top surface 11, thus forming a shape that is wider at the top and narrower at the bottom, or as shown in this embodiment, it extends to a certain height and then no longer expands outwards but is changed to be connected to the vertical side edge 13. Each of the two long side edges 131 of the adsorption seat is provided with a recess 18 to facilitate the user to have a force application point when flipping the adsorption seat.

[0031] By adopting the above structure of the present invention, the installation and use method of the adsorption seat 10 is the same as that of existing products. It also uses the magnetic force of the magnet of the adsorption seat to adsorb the adsorption seat at the position to be installed, so a suction force of the same magnitude F1 + F2 + F********** Figure 8 Please refer to Figure 8 . Taking the schematic direction as an example for explanation, when the user holds the recess 18 of the adsorption seat and rotates the adsorption seat counterclockwise with the lower left corner of the adsorption seat as the rotation fulcrum O, assuming the same rough calculation method, because the bottom surface of the present invention is reduced, the distance between the outermost iron sheet and the long side edge will be very small, which can be regarded as the fulcrum O being at the position of F1. Therefore, the resistance moment formed by the bottom surface of the present invention from left to right is D*F2 + 2D*F3 + 3D*F4 = L4, which is significantly less than the resistance moment formed by existing products.

[0032] The force applied by the user will form a turning moment L3, and the adsorption seat will have a resistance moment L4 due to the suction force of the magnet to counter it. However, from the perspective of the structure, it can be clearly seen that the length of the turning moment L3 is much longer than that of the adsorption moment L4. According to the principle of the lever, the larger the moment, the more labor-saving. Coupled with the fact that the resistance moment formed by the present invention is already smaller than that of the existing products, the user can easily turn the adsorption seat, so that the bottom surface of the adsorption seat no longer adheres to the plane, thereby achieving the purpose of being able to remove the adsorption seat very labor-savingly.

[0033] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
