[0002] The clothes drying racks used in households are generally composed of a support rod part, a hook vertical part, and a hook bent part connected in sequence. There are two problems when using them. First, the opening of the hook bent part is relatively large. When it is hung on a clothesline or clothesline, the clothes are easily blown by the wind and the clothes drying rack is easy to fall off the clothesline / rope; second, the clothes are supported on the support rod part and are also easy to slip off and fall off with the wind. However, the clothes drying racks in the prior art are generally not equipped with a self-locking device that is easy to disassemble, suitable for different clothes hangers, and can press and fix clothes and seal the opening of the hook bent part. In order to solve the above technical problems, the present application provides a clothes drying rack self-locking device based on the lever principle. Utility Model Content

DETAILED DESCRIPTION

[0023] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] like Figure 1-5 As shown, a clothes drying rack self-locking device based on the lever principle, the clothes drying rack includes a support rod portion, a hook vertical portion, and a hook curved portion connected in sequence; the self-locking device includes a mounting frame 1 detachably connected to the clothes hanger hook vertical portion, at least one connecting seat 2 provided on one side of the mounting frame 1, two rotating rods 3 rotatably connected to the connecting seat 2 via a rotating shaft, a hook head pressing seat 5 provided at the movable end of the two rotating rods 3 near the hook curved portion, a telescopic rotating member provided at one end of the rotating rod 3 away from the hook head pressing seat 5, and an elastic pressing block 12 connected to the telescopic rotating member;

[0025] A torsion spring 4 is provided between the connecting seat 2 and the rotating rod 3. The hook head pressing seat 5 is pressed on the movable end of the hook bending part under the torsion force of the torsion spring 4, and the elastic pressing block 12 is pressed on the surface of the support rod part under the torsion force of the torsion spring 4 to form a locking state.

[0026] It should be noted that, in this embodiment, the torsion spring 4 is sleeved outside the rotating shaft;

[0027] In this embodiment, taking the rotation connection position of the rotating rod 3 and the connecting seat 2 as a reference point, the total weight of the end of the connecting seat 2 connected to the hook head pressing seat 5 is less than the total weight of the end of the connecting seat 2 connected to the elastic pressing block 12. Under the action of its own weight, the hook head pressing seat 5 will also move up and press on the movable end of the hook bending part, and the elastic pressing block 12 will also press down on the surface of the support rod part. When clothes are hung on the support rod part, the elastic pressing block 12 will press the clothes on the support rod part to reduce or prevent the problem of clothes falling off. By pressing the hook head pressing seat 5 on the movable end of the hook bending part, a self-locking state is formed, which can reduce or prevent the situation where the clothes drying rack is blown off by the wind.

[0028] And under the torsion of the torsion spring 4, the hook head pressing seat 5 can be pressed more tightly and stably on the movable end of the hook bending part, and the elastic pressing block 12 can be pressed more tightly and stably on the surface of the support rod part, further increasing stability.

[0029] Preferably, the telescopic rotating member includes a moving rod 8 slidingly connected to the rotating rod 3, a fixing member 9 for fixing the moving rod 8 and the rotating rod 3, a rotating seat 10 rotatably connected to the fixing member 9 at one end away from the rotating rod 3, and a fixing member 2 11 for fixing the moving rod 8 and the rotating seat 10, and the elastic pressing block 12 is fixedly connected to the rotating seat 10.

[0030] When in use, the length of the elastic pressing block 12 from the connecting seat 2 and the angle of the elastic pressing block 12 relative to the connecting seat 2 can be adjusted, so that the position of the elastic pressing block 12 can be easily adjusted to suit clothes drying racks of different shapes or lengths. It has a wide range of applications and is easy to use.

[0031] Preferably, the mounting frame 1 includes two detachably connected frames 101, a plurality of clamping tubes 104 and clamping rods 105 arranged inside the two frames 101, the clamping rods 105 are clamped inside the clamping tubes 104, and the upper and lower end surfaces of the two frames 101 are provided with through holes 102 for the vertical part of the hook to pass through.

[0032] It should be noted that the connecting socket 2 in the present application is arranged on one side of one of the frames 101 .

[0033] Furthermore, a sealing gasket 103 is provided on the inner wall of the through hole 102 and is in contact with the vertical portion of the hook. The outer walls of the two frames 101 extend to form a connecting portion, and the connecting portion is provided with a fixing member 3.

[0034] It should be noted that, in this embodiment, the fixing member 1 9 , the fixing member 2 11 and the fixing member 3 are all fixing bolts.

[0035] During installation, the frame 101 can be fixed on the vertical part of the hook by correspondingly connecting the clamping tubes 104 and the clamping rods 105 on the two frames 101. In order to increase the connection stability of the two installation frames 1 on the vertical part of the hook, the present application also connects and fixes the two frames 101 together through fixing bolts, and presses the sealing gasket 103 against the surface of the vertical part of the hook. After the two frames 101 are fixed, the hook head pressing seat 5, telescopic rotating part and elastic pressing block 12 connected to the frame 101 are all fixed on the vertical part of the hook, which is convenient for disassembly and installation, and also convenient for installation and replacement on different clothes drying racks, and easy to use.

[0036] Preferably, a hook head clamping groove 6 is provided on one side of the hook head pressing seat 5 close to the movable end of the hook bending portion, and the hook head clamping groove 6 is used to clamp the movable end of the hook bending portion.

[0037] Furthermore, a magnet block 7 is provided inside the hook head clamping groove 6. The vertical part and the curved part of the hook of the clothes drying rack used in general households are made of metal materials such as iron that can be attracted by the magnet block 7. The magnet block 7 can adsorb and fix the movable end of the curved part of the hook made of metal materials such as iron on the magnet block 7, so that the movable end of the curved part of the hook is tightly connected and fits on the magnet block 7, which can further improve the stability of the hook head pressing seat 5 pressing on the movable end of the curved part of the hook.

[0038] Preferably, a hanging ring 13 is provided at the top of the two rotating rods 3 on one side of the movable rod 8, which is convenient for carrying by hand or supporting the hanging ring 13 through the clothesline, and then pulling up to move the hook head pressing seat 5 down, that is, the hook head pressing seat 5 no longer presses the movable end of the hook bending part, and the elastic pressing block 12 no longer presses the support rod part, that is, the locking state is released, which is convenient for hanging clothes, taking off clothes, hanging clothes racks and taking off clothes racks.

[0039] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
