DETAILED DESCRIPTION

[0028] The embodiments of the utility model will be described in detail below with reference to the drawings.

[0029] As Figures 1-9 shown, a micro switch installation structure comprises a box body 1 and a box cover 2 installed at the opening of the box body 1, and a micro switch 3 for sensing the opening and closing state of the box cover 2 is installed at the opening of the box body 1; the top of the micro switch 3 is provided with a push piece 31 for sensing the micro motion, and the bottom of the box cover 2 is formed with a forward support 21 for pressing down the push piece 31 installed in the forward direction and a reverse support 22 for pressing down the push piece 31 installed in the reverse direction; the box body 1 is formed with an installation site 4 for installing the micro switch 3, and the bottom of the micro switch 3 is provided with a support frame 44 for supporting the height of the micro switch 3.

[0030] The micro switch 3 is in contact with the box cover 2, and the micro switch 3 is triggered under the opening action of the box cover 2, so that the micro switch 3 can detect and identify the opening and closing state of the box cover 2.

[0031] The bottom of the forward support 21 is used for abutting with the push piece 31 installed in the forward direction, and when the box cover 2 is opened, the upward opening of the box cover 2 drives the synchronous movement of the forward support 21, so that the bottom of the forward support 21 is separated from the push piece 31, and the push piece 31 is triggered under the action of its own elastic force.

[0032] The bottom of the reverse bracket 22 is used to abut the forwardly installed push piece 31. When the box cover 2 is opened, the upward opening of the box cover 2 drives the synchronous movement of the reverse bracket 22, so that the bottom of the reverse bracket 22 is separated from the push piece 31, and the push piece 31 is triggered under the action of its own elastic force.

[0033] The forward bracket 21 and the reverse bracket 22 are located above the installation position 4, and the bottom of the forward bracket 21 and the reverse bracket 22 abuts the push piece 31. The forward bracket 21 and the reverse bracket 22 are arranged in parallel, and the spacing between the forward bracket 21 and the reverse bracket 22 is less than the length of the push piece 31.

[0034] So that no matter whether the micro switch 3 is forwardly installed or reversely installed, the forward bracket 21 and the reverse bracket 22 are abutted with the push piece 31 at the same time, and the forward bracket 21 and the reverse bracket 22 are arranged in the range of the push piece 31. During installation, the installation direction of the micro switch 3 does not need to be considered.

[0035] The installation position 4 includes at least two positioning ribs 41 formed on the box body 1, and the micro switch 3 is formed with positioning holes 32 corresponding to the positioning ribs 41. The number of the positioning holes 32 is consistent with the number of the positioning ribs 41.

[0036] The at least two positioning holes 32 are arranged in a center of the micro switch 3, which ensures that the at least two positioning holes 32 are always located at the same position when the micro switch 3 is forwardly installed or reversely installed, so as to facilitate the installation of the micro switch 3 to the same position when the micro switch 3 is forwardly installed or reversely installed.

[0037] The installation position 4 further includes an abutment edge 42 formed on the box body 1. The abutment edge 42 is formed on opposite sides of the micro switch 3, and the abutment edge 42 abuts the side edges of the micro switch 3.

[0038] The abutment edge 42 abuts the side edges of the micro switch 3 to limit the horizontal transverse direction freedom of the micro switch 3, so as to ensure the stable installation of the micro switch 3 in the box body 1.

[0039] The end of the abutment edge 42 is formed with a buckle member 43 for buckling the micro switch 3. The buckle member 43 is buckled with the opposite sides of the micro switch 3.

[0040] The buckle member 43 is buckled with the side edges of the micro switch 3 to limit the horizontal longitudinal direction freedom of the micro switch 3, so as to ensure the stable installation of the micro switch 3 in the box body 1 in combination with the abutment edge 42 abutting the side edges of the micro switch 3.

[0041] The support frame 44 is located at the bottom of the micro switch 3, and the bottom of the support frame 44 abuts against the bottom of the micro switch 3. The support frame 44 is used to support the height of the micro switch 3, so as to ensure that the micro switch 3 is arranged at the opening of the box body 1. Meanwhile, the support frame 44 limits the vertical direction freedom of the micro switch 3, so as to ensure the stable installation of the micro switch 3 in the box body 1.

[0042] The top of the support frame 44 is formed with a guide round corner 45 which is convenient for installing the micro switch 3. The guide round corner 45 can play a certain guiding role in the installation of the micro switch 3, so as to facilitate the installation of the micro switch 3.

[0043] The micro switch 3 is installed on the inner wall of the box body 1, and the toggle 31 is arranged flush with the opening of the box body 1, so as to facilitate the accurate identification of the opening and closing of the box cover 2 by the micro switch 3.

[0044] The box body 1 is provided with a hinge 11 connected with the box cover 2 and a locking piece 12 used for locking the box cover 2. The box cover 2 is rotationally connected with the box body 1 under the action of the hinge 11, so as to realize the opening and closing of the box cover 2. The locking piece 12 is used for locking the box cover 2 and the box body 1 in the closed state.

[0045] In actual use, the position of the installation site 4 is observed, and the toggle of the micro switch 3 is installed towards the opening of the box body 1, without considering the forward installation or reverse installation of the micro switch 3. Under the action of the guide round corner 45, the installation position of the micro switch 3 is guided, and the micro switch 3 is clampedly installed in the box body 1 under the action of the buckle piece 43, so as to ensure the stable installation of the micro switch 3.

[0046] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application; therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.

[0047] Although the terms such as box body 1, hinge 11, locking piece 12, box cover 2, forward support frame 21, reverse support frame 22, micro switch 3, toggle 31, positioning hole 32, installation site 4, positioning rib 41, abutting edge 42, buckle piece 43, support frame 44, guide round corner 45, etc. are used more frequently in the drawings, but the possibility of using other terms is not excluded.
