Detailed ways

The utility model will be described in further detail below through specific embodiments in conjunction with the accompanying drawings. It should be noted here that the descriptions of these implementations are used to help understand the utility model, but are not intended to limit the utility model. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute conflicts with each other.

Please refer to Figures 1 to 6, which show a front-mounted quick installation structure used on the control panel. The front-mounted quick installation structure is mainly composed of a panel body 1 , a threaded casing 3 and a threaded bushing 2 and other components.

The panel body is formed with a square-shaped installation hole 10 penetrating vertically downward from the top surface of the panel body to the bottom surface of the panel body. The inner peripheral surface of the installation square hole has four sides of the square hole. Furthermore, rounded corners make a smooth transition between the sides of two adjacent square holes.

The threaded casing is composed of an upper part 31 and a lower part 32 of the casing. The upper part of the shell is a circular head. The outer diameter of the upper part of the housing is larger than the side length of the mounting square hole, so as to limit the downward movement of the threaded housing. An anti-skid portion is provided on the upper part of the housing. The anti-skid portion is formed on the upper part of the casing and is arranged in a polygonal structure on the side of straight segments. In this embodiment, the polygonal structure is a hexagon. The function of the anti-slip part is to prevent the operator's fingers from sliding on the outer circle of the upper part of the housing during installation or disassembly. The upper part of the housing is above the panel body, and the bottom surface of the upper part of the housing is in surface contact with the top surface of the panel body. The lower part of the casing extends downwards from the bottom surface of the upper part of the casing. The lower part of the shell is a circular cylinder. External threads are formed on the outer peripheral surface of the lower part of the housing.

The threaded bushing consists of a bushing upper part 21 and a bushing lower part 22 . The lower part of the bush is a square structure. The lower part of the bushing corresponds to the installation square hole, that is, the outer peripheral surface of the lower part of the bushing is the same as the inner peripheral surface of the installation square hole (that is, the same shape and/or size), so that the bushing The lower part of the sleeve can enter the bottom of the panel body from above the panel body through the installation square hole. The outer peripheral surface of the lower part of the bushing has four lower side faces of the bushing. The lower part of the bush is below the panel body. The top surface of the lower part of the bush is in surface contact with the bottom surface of the panel body. The outer peripheral surface of the lower part of the bushing and the inner peripheral surface of the installation square hole have a common vertical centerline, and the outer peripheral surface of the lower part of the bushing and the inner peripheral surface of the installation square hole intersect each other in a horizontal direction. 45° to limit the upward movement of the threaded bushing. The upper part of the bush extends vertically upward from the top surface of the lower part of the bush. The bushing upper portion is confined within an area bounded by the outer peripheral surface of the bushing lower portion. The outer peripheral surface of the upper part of the bush is surrounded by four identical shaped side faces in a clockwise direction. The special-shaped side faces are a broken line section surface 213 , an arc line section surface 211 and a tangent line section surface 212 which are sequentially connected clockwise. Wherein, each profiled side corresponds to a lower side of the bushing. The tangent segment surface coincides with the corresponding lower side surface of the bush in the vertical direction. The surface of the broken line section forms an included angle of 45° with the corresponding lower side of the bush. The upper part of the bush is accommodated in the installation square hole. The four broken-line segment surfaces on the upper part of the bush are respectively in surface contact with the four square hole sides of the inner peripheral surface of the installation square hole. The arc line section surface is a transition surface connecting the broken line section surface and the tangent line section surface, and is used to avoid jamming during the clockwise rotation of the upper part of the bush in the installation square hole.

The threaded bushing is provided with a threaded through hole extending vertically downward from the top surface of the upper part of the bushing to the bottom surface of the lower part of the bushing. Internal threads corresponding to the external threads are formed on the inner peripheral surface of the threaded through hole. The lower part of the shell passes through the threaded through hole, and the threaded shell is fixedly combined with the threaded bushing through the cooperation of the external thread and the internal thread.

Installation method: provide the panel body, the threaded shell and the threaded bushing. Assembling said threaded housing and said threaded bushing constitutes an integral part. Align the threaded bushing with the installation square hole of the panel body (at this time, the tangent section surface of the lower part of the bushing corresponds to the straight section surface of the installation square hole). The lower part of the bushing passes through the square installation hole downwards from above the square hole until the top surface of the lower part of the bushing is flush with the bottom surface of the panel body. Rotate the threaded bush clockwise, after turning 45°, the broken line section surface on the upper part of the bush just corresponds to the straight line section surface of the installation square hole, so as to limit the smoothness of the threaded bushing degrees of freedom in the circumferential direction of the hour hand. Through the upper part of the housing, the upper positioning of the integral part is carried out. Through the lower part of the bushing, the lower positioning of the integral part is carried out.

The above only expresses the embodiment of the utility model, and its description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the scope of protection of the utility model patent should be based on the appended claims.
