[0032] Some existing electrical switches include a base box and a panel 100. The base box can be pre-installed on the wall in an open or concealed manner, and then the panel 100 is locked to the base box by means of screws and washers 220. Usually, the panel 100 is provided with a mounting hole 110, and a countersunk groove 120 is provided at the hole end of the mounting hole 110. The countersunk groove 120 is used to accommodate the screw head 211 and the washer 220. In the process of the panel 100 being locked to the base box by screws and washers 220, the washer 220 and the screw are in a clearance fit, which is easy to cause deviation and is difficult to slide directly into and flatten to the bottom of the countersunk groove 120. It is necessary to manually align the washer 220 and place it into the countersunk groove 120, which affects the installation efficiency of the panel 100.

[0033] Reference Figures 1 to 6 , is a panel mounting structure of an embodiment of the utility model, comprising a panel 100 and a locking assembly 200. The panel 100 is provided with a mounting hole 110, and a countersunk groove 120 is provided at the hole end of the mounting hole 110; the locking assembly 200 comprises a threaded fastener 210 and a washer 220, the washer 220 is sleeved on the threaded fastener 210, the threaded fastener 210 is passed through the mounting hole 110, and the washer 220 and the screw head 211 of the threaded fastener 210 are accommodated in the countersunk groove 120; wherein the countersunk groove 120 is provided with a positioning portion 130 at a part of the notch periphery, and the positioning portion 130 is used to guide the washer 220 into a position aligned with the countersunk groove 120 when the threaded fastener 210 is rotated and fastened.

[0034] During the process of installing the panel 100 to the bottom box through the locking assembly 200, the threaded fastener 210 is first inserted into the mounting hole 110, and then the threaded fastener 210 is rotated and tightened. If the washer 220 is not aligned and slides into the countersunk groove 120, the threaded fastener 210 drives the washer 220 to rotate, and the washer 220 can rotate and press against the alignment part 130. The alignment part 130 pushes the washer 220 to displace, and guides the washer 220 to align with the countersunk groove 120. Then, the washer 220 can slide into the countersunk groove 120. There is no need to manually align the washer 220 with the countersunk groove 120, so that the washer 220 can be more easily aligned and slide into the bottom of the countersunk groove 120, thereby improving the installation efficiency of the panel 100.

[0035] In the embodiment, an alignment block 140 is disposed at the periphery of the slot opening of the countersunk slot 120, and the side wall of the alignment block 140 close to the central axis of the mounting hole 110 is aligned with the slot wall of the countersunk slot 120, and the side of the alignment block 140 close to the central axis of the mounting hole 110 forms an alignment portion 130. When the washer 220 does not slide into the countersunk slot 120, the washer 220 is in a biased state and the threaded fastener 210 can drive the washer 220 to rotate. When the washer 220 rotates to contact the alignment block 140 on the side close to the central axis of the mounting hole 110, since the alignment block 140 is fixed on the panel 100, the washer 220 continues to rotate and is pushed and displaced until the washer 220 is aligned with the countersunk groove 120, so that the washer 220 can slide into and lie flat on the bottom of the countersunk groove 120; the alignment block 140 is used to achieve the gradual alignment of the washer 220 with the countersunk groove 120 during the rotation process, the structure is simple, and the processing is relatively convenient, and no additional process is required to align the washer 220 with the countersunk groove 120.

[0036] In the embodiment, the radial dimension of the alignment block 140 along the central axis of the mounting hole 110 increases first and then decreases along the central axis direction surrounding the mounting hole 110. The above structure makes the structural strength of the alignment block 140 higher and facilitates the processing and forming of the alignment block 140. It is conceivable that the alignment block 140 can also be in other shapes, for example, the alignment block 140 is in the shape of a rib, and the washer 220 can be pushed to align with the countersunk groove 120 when the washer 220 rotates.

[0037] In other embodiments, the alignment portion 130 is a default recess 150 provided on a part of the groove wall of the countersunk groove 120. With the default recess 150 as the alignment portion 130, when the locking assembly 200 rotates, the washer 220 can be easily placed in the default recess 150, and then the washer 220 rotates with the threaded fastener 210 until the washer 220 is pushed by the periphery of the default recess 150, that is, the alignment portion 130 pushes the washer 220 to align with the countersunk groove 120, and then the washer 220 slides into the bottom of the countersunk groove 120. The alignment portion 130 is formed by the periphery of the default recess 150, the structure is simple, and the structural strength of the panel 100 is high.

[0038] In the embodiment, two default recesses 150 are provided and distributed around the central axis of the mounting hole 110. With the above structure, the washer 220 can be more easily pushed and displaced by the periphery of the default recess 150 when rotating, so that the washer 220 is aligned with the countersunk groove 120.

[0039] In the embodiment, the washer 220 is provided with a clearance through hole 221, and the washer 220 is sleeved on the threaded fastener 210 through the clearance through hole 221, and the mounting hole 110 and the clearance through hole 221 are both bar-shaped holes. The mounting hole 110 and the clearance through hole 221 are both bar-shaped holes. If the panel 100 is installed on the bottom box through the threaded fastener 210 and there is a slight misalignment, the position of the panel 100 relative to the bottom box can be fine-tuned along the length direction of the bar hole, so that the position of the panel 100 installed on the bottom box is more accurate, and there is no need to repeatedly disassemble and assemble the panel 100 to make the installation position accurate.

[0040] In the embodiment, the distance between the outer peripheral wall of the gasket 220 and the hole wall of the clearance through hole 221 is uniformly set along the central axis direction of the clearance through hole 221, and the countersunk groove 120 is a strip groove. With the above structure, the strength of the gasket 220 along the central axis direction of the clearance through hole 221 is basically the same, and after the gasket 220 enters the countersunk groove 120, since both the gasket 220 and the countersunk groove 120 are non-circular structures, the gasket 220 cannot rotate in the countersunk groove 120, thereby reducing the wear of the gasket 220 and the bottom of the countersunk groove 120.

[0041] It is conceivable that the outer peripheral wall of the gasket 220 may also be circular, and similarly, the countersunk groove 120 may also be a circular groove. Those skilled in the art may make specific configurations according to actual needs.

[0042] Specifically, a strip-shaped hole or a strip-shaped groove refers to a shape in which the length in the cross section is greater than the width.

[0043] In the embodiment, the cross section of the mounting hole 110 is the same as the cross section of the clearance through hole 221 , so that the panel 100 can be fine-tuned relative to the threaded fastener 210 . The structure is simple and easy to implement.

[0044] In the embodiment, the threaded fastener 210 further includes a column, which is provided with a stud section 212 and a light column section 213, the screw head 211 is connected to the light column section 213, and the washer 220 is sleeved on the light column section 213. The above structure makes it difficult for the washer 220 to be separated from the light column section 213, so that the screw and the washer 220 can be used together.

[0045] It is conceivable that the threaded fastener 210 may also be a bolt or a screw of other structures, and those skilled in the art may configure the specific configuration according to actual needs.

[0046] The utility model also discloses a switch, which adopts the panel installation structure. By adopting the panel installation structure, the assembly efficiency of the switch can be improved.
