DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0026] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0027] The directions and positions mentioned in the present invention, such as "upper", "lower", "front", "back", "left", "right", "inside", "outside", "top", "bottom", "side", etc., are only for reference to the directions or positions of the drawings. Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.

[0028] like Figures 1 to 5 As shown in the figure, in an embodiment of the utility model, a hook storage structure of a wall switch comprises a base 1, a fixing frame 2 and a hook 3. The hook 3 is swingably arranged on the base 1 or the fixing frame 2, with one end thereof facing the base 1 as an operating end 31 for controlling its swing. The base 1 or the fixing frame 2 is provided with a swing opening 11, and the operating end 31 is inserted into the base 1 or the fixing frame 2 through the swing opening 11.

[0029] The base 1 or the fixing frame 2 extends a first channel 12 in a first direction A above the operating end 31 and communicates with the swing opening 11. A mounting block 5 is fixed at a position of the first channel 12 in the first direction A.

[0030] The operating end 31 is penetrated by an adjusting screw 4 , the diameter of the first channel 12 is larger than the diameter of the threaded rod of the adjusting screw 4 , and the tail of the adjusting screw 4 penetrates into the first channel 12 from bottom to top and forms a threaded fit with the mounting block 5 .

[0031] Through this arrangement, a threaded connection is formed between the mounting block fixed in the base or the fixing frame and the adjusting threaded member, thereby improving the stability of the connection between the adjusting threaded member and the base or the fixing frame. At the same time, in this embodiment, threaded holes can be processed on the mounting block in advance. Compared with forming threaded holes on the base or the fixing frame, threaded holes formed on the mounting block reduce the processing difficulty.

[0032] The base 1 or the fixing frame 2 is horizontally provided with a first mounting groove 13 at a position on the first direction A of the first channel 12. The end of the first mounting groove 13 away from the horizontal center of the base 1 penetrates the base 1 or the fixing frame 2 and forms a first through opening 131. The mounting block 5 passes through the first through opening 131 and is limitedly installed in the first mounting groove 13.

[0033] Through this arrangement, the convenience of installing the mounting block is improved.

[0034] The first mounting groove 13 has a first limiting surface 132 that forms a limiting fit with the upper end surface of the mounting block 5 and a second limiting surface 133 that forms a limiting fit with the lower end surface of the mounting block 5. The distance between the first limiting surface 132 and the second limiting surface 133 gradually decreases from the first opening 131 to the end of the first mounting groove 13 away from the first opening 131.

[0035] The diameter of the first through opening is greater than the height of the mounting block, and the height of the first mounting groove away from one end of the first through opening is less than the height of the mounting block. Through this arrangement, the convenience of installing the mounting block into the first mounting groove and the stability of the mounting block being limited in the first mounting groove are improved, while the requirements for the processing accuracy of the mounting block are reduced.

[0036] The first limiting surface 132 is an inclined surface, and the second limiting surface 133 is a horizontal surface.

[0037] This arrangement ensures that the bottom surface of the mounting block is perpendicular to the rod of the adjusting screw when the mounting block is installed in the first mounting groove, thereby improving the convenience of installing the adjusting screw into the mounting block and the stability of its connection with the mounting block. In this embodiment, the inclined surface and the horizontal surface are relative to the first direction A, and the horizontal surface specifically refers to a plane perpendicular to the first direction A.

[0038] The upper end surface and / or lower end surface of the first mounting groove 13 is provided with a limiting convex strip 14 extending in the same direction as the first mounting groove 13, and the end surface of the limiting convex strip 14 close to the center of the first mounting groove 13 in the first direction A forms a first limiting surface 132 and / or a second limiting surface 133.

[0039] Through this arrangement, the convenience of installing the mounting block into the first mounting groove is further improved. In this embodiment, a limiting convex strip is specifically selected to be arranged on the upper end surface of the first mounting groove, and two of them are arranged in parallel to keep the bottom surface of the mounting block perpendicular to the rod of the adjusting screw member during the process of installing the mounting block into the first mounting groove, while improving the stability of the cooperation between the first mounting groove and the mounting block.

[0040] One end of the limiting convex strip 14 close to the first through opening 131 is in smooth transition with the upper end surface and / or the lower end surface of the first installation groove 13 .

[0041] Through this arrangement, the wear on the mounting block during the process of installing the mounting block into the first mounting groove is reduced.

[0042] The hook body 3 includes a swinging piece 311 and two limiting pieces 321 arranged in parallel and connected on both sides of the swinging direction of the swinging piece 311. The bottom of the swinging piece 311 forms an operating end 31. The limiting piece 321 extends to the outside of the base 1 to form a limiting end 32 that cooperates with the inner wall of the junction box. The base 1 is provided with a storage groove 15 that cooperates with the limiting piece 321. The side walls of the storage groove 15 are respectively provided with limiting blocks 16. When the limiting piece 321 is pressed into the storage cavity 151, the limiting block 16 abuts against the edge of the limiting piece 321 to prevent the limiting piece 321 from flipping to the outside of the base 1.

[0043] The operating end 31 has a limit protrusion 312 extending upward from one end close to the horizontal center of the base 1 . When the limit end 32 forms a limit fit with the inner wall of the junction box, the limit protrusion 312 abuts against the cavity wall of the base 1 .

[0044] Through this arrangement, the limiting protrusion further improves the stability of the cooperation between the hook body and the junction box.

[0045] The surface of the limiting block 16 is a hemispherical surface.

[0046] With this arrangement, when the limiting piece needs to be stored in the storage slot or flipped out of the storage slot, the operation is more labor-saving and it is not easy to cause damage to the limiting piece.

[0047] The hook body 3 is swingably disposed on the base 1 , a swing opening 11 is located on the base 1 , and the operating end 31 penetrates into the base 1 or the fixing frame 2 through the swing opening 11 .

[0048] Through this arrangement, the hook structure is arranged on the base, so that the structure can be applied to European standard switches with a higher overall structure.

[0049] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
