[0018] The present invention is further described in detail below by means of specific embodiments in combination with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. 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 conflict with each other.

[0019] See also Figures 1 to 6 , the figure shows a front-mounted quick installation structure for a control panel. The installation structure is mainly composed of a panel body 1, a housing body 22 and a positioning assembly 33.

[0020] The panel body 1 is provided with a mounting square hole 11 and a semicircular slot 12 which are vertically penetrated downward from the top surface of the panel body 1 to the bottom surface of the panel body 1. There are two semicircular slots 12 which are arranged opposite to each other. The inner circumference of the mounting square hole 11 has four square hole side surfaces.

[0021] The housing body 2 is composed of a circular upper portion 21 located above the mounting square hole 11, a special-shaped middle portion 22 located inside the mounting square hole 11, and a square lower portion 23 located below the mounting square hole 11. The circular upper portion 21 is larger than the mounting square hole 11, so that the bottom surface of the circular upper portion 21 is in surface contact with the top surface of the panel body 1. An upper notch 210 is formed on the circular upper portion 21 at the semicircular slot 12. The square lower portion 23 has the same shape and size as the mounting square hole 11. The square lower portion 23 has four lower side surfaces, the square lower portion 23 and the mounting square hole 11 have a common vertical center line and the square lower portion 23 and the mounting square hole 11 intersect at 45° in the horizontal direction, the square lower portion 23 is formed with a receiving hole at the semicircular slot 12, the special-shaped middle portion 22 is surrounded by four special-shaped side surfaces in a clockwise direction, the special-shaped side surfaces are a fold line segment surface 221, an arc segment surface 222 and a tangent segment surface 223 connected in sequence in a clockwise direction, wherein the fold line segment surface is in surface contact with the corresponding side surface of the square hole, the tangent segment surface is overlapped with the corresponding side surface of the lower portion in the vertical direction, and the arc segment surface is a transition surface connecting the fold line segment surface and the tangent segment surface. The shell is composed of a circular outer circle, a polygonal outer circle and a square outer circle. After installation, the circular outer circle and the square outer circle limit the axial freedom of the shell relative to the panel body; the polygonal outer circle on the shell is a shape surrounded by four groups of "arc-tangent-45° broken line". After the square outer circle of the shell passes through the square hole of the panel body, it continues to rotate 45° clockwise. At this time, the 45° broken line outer circle and the mounting hole are offset, and the clockwise rotation freedom of the shell is limited; the circular outer circle on the shell has two notches, and the shape and position of the notches correspond to the shape and position of the circular hole on the square outer circle and the shape and position of the semicircular notch of the upper hole of the panel body. After installation, the positioning pin passes through the above three corresponding slots to limit the counterclockwise rotation freedom of the shell; the mounting hole on the panel body is A square hole with the same size as the square outer circle of the shell. During installation, the square outer circle of the shell can directly pass through the square hole, while the round head of the shell cannot pass through, ensuring that the sensor can be front-mounted; two arc slots are provided on a set of opposite sides of the square hole of the panel body, and the shape and position of the slots correspond to the shape and position of the two slots on the circular outer circle of the shell. After the installation is completed, the positioning pin passes through the above three corresponding slots to limit the counterclockwise rotation freedom of the shell; the position locking mechanism composed of the positioning pin, pin spring, spring guide rod and back cover presses the positioning pin to below the lower end face of the panel body before installation, and the rear shell can rotate 45° clockwise, and then releases the positioning pin, and the pin passes through the corresponding slots on the panel body and the circular outer circle of the shell to limit the counterclockwise rotation freedom of the shell.

[0022] The positioning assembly 3 is accommodated in the accommodation hole 230. The positioning assembly 3 comprises a spring guide rod 31, a pin spring 32 and a positioning pin 33 located above the pin spring. The positioning pin passes through the accommodation hole and extends into the upper notch.

[0023] The special-shaped side surface is provided with an avoidance portion to avoid the positioning pin.

[0024] The shell is composed of a circular outer circle, a polygonal outer circle and a square outer circle. After installation, the circular outer circle and the square outer circle limit the axial freedom of the shell relative to the panel body.

[0025] The polygonal outer circle on the shell is a shape surrounded by four groups of "arc - tangent - 45° fold line". After the square outer circle of the shell passes through the square hole of the panel body, it continues to rotate 45° clockwise. At this time, the 45° fold line outer circle is against the mounting hole, and the clockwise rotation freedom of the shell is restricted.

[0026] The circular outer circle on the shell has two notches, and the shape and position of the notches correspond to the shape and position of the circular hole on the square outer circle and the shape and position of the semicircular notch of the hole above the panel body. After installation is completed, the positioning pin passes through the above three corresponding slots to limit the counterclockwise rotation freedom of the shell.

[0027] The mounting hole on the panel body is a square hole with the same size as the square outer circle of the shell. During installation, the square outer circle of the shell can directly pass through the square hole, while the round head of the shell cannot pass through, ensuring that the sensor can be front-mounted.

[0028] There are two arc slots on a set of opposite sides of the hole above the panel body. The shape and position of the slots correspond to the shape and position of the two slots on the circular outer circle of the shell. After installation is completed, the positioning pin passes through the above three corresponding slots to limit the counterclockwise rotation freedom of the shell.

[0029] The position locking mechanism composed of the positioning pin, pin spring, spring guide rod and back cover shown in the figure is that the positioning pin is pressed to below the lower end surface of the panel body before installation, and the rear shell can be rotated 45° clockwise. Then the positioning pin is released, and the pin passes through the corresponding notches on the circular outer circle of the panel body and the shell, limiting the counterclockwise rotation freedom of the shell.

[0030] The above only expresses the implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
