Therefore, the elevator operation box is a very important part for users. The elevator operation box generally includes various buttons and emergency call buttons, etc.

[0003] The elevator operation box includes a panel assembly and a bottom box. Most of the traditional panel assemblies and bottom boxes adopt a snap connection structure. Due to multiple disassembly and assembly, the problem of panel flatness deformation will occur; moreover, the existing elevator operation box is cumbersome to assemble and troublesome to maintain later.

[0022] The following further elaborates on the present utility model in combination with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by the appended claims of this application.

[0023] The implementation mode of the present utility model relates to a peripheral type up and down magnetic adsorption elevator operation box, as Figures 1-6 shown, including a panel assembly 1 and a bottom box 2. The panel assembly 1 includes an adsorption frame 7 and a panel 8 installed in the adsorption frame 7. On both sides of the rear end of the adsorption frame 7, a plurality of sucking and guiding columns 9 are arranged side by side along the edge. The panel 8 is provided with a control button 5 and a display screen 6. A circuit board 3 connected to the control button 5 and the display screen 6 is installed inside the bottom box 2. A plurality of magnets 4 are evenly installed at the inner wall of the front end opening of the bottom box 2. The plurality of sucking and guiding columns 9 at the rear end of the adsorption frame 7 are inserted along the inner wall of the bottom box 2 and the adsorption frame 7 is sucked by the plurality of magnets 4, and the adsorption frame 7 is closely attached to the front end opening of the bottom box 2.

[0024] The present utility model designs a plurality of sucking and guiding columns 9 on both side edges of the adsorption frame 7. The sucking and guiding columns 9 can play a role in accurate assembly positioning during product assembly, and the length of the sucking and guiding columns 9 also solves the problem of free sucking at the end of magnetic adsorption; a plurality of magnets 4 are evenly installed at the inner wall of the bottom box 2, and the front end face of the magnet 4 is flush with the front end face of the front end opening of the bottom box 2, which can effectively avoid the phenomenon of the magnet being broken when being impacted by positive sucking; the distribution design of the magnets 4 adopts a marginalized design, which effectively solves the phenomenon of uneven sucking surface after the product is sucked. The present utility model adopts an up and down magnetic adsorption structure to achieve rapid assembly and facilitate later maintenance.

[0025] The length and width dimensions of the adsorption frame 7 are larger than the length and width dimensions of the inner wall of the bottom box 2. Therefore, the adsorption frame 7 cannot be installed into the bottom box 2, and the adsorption frame 7 can only be attached to the opening of the bottom box 2.

[0026] As the material description of the bottom box 2 and the adsorption frame 7, both the bottom box 2 and the adsorption frame 7 are made of galvanized steel plates; the adsorption frame 7 can also be made of other metals or alloys that can be adsorbed by the magnet 4, as long as the required rigidity is satisfied.

[0027] As an explanation of the mounting structure of the magnet 4, two threaded studs 10 are arranged side by side at the inner wall of the bottom box 2 corresponding to the position of each magnet 4. The two threaded studs 10 pass through the corresponding magnet 4 and are each screwed with a locking nut 11. The magnet 4 is convenient to install. When replacing, just unscrew the locking nut 11, take out the damaged magnet 4, reinstall the good magnet 4, and screw in the locking nut 11 for fixation.

[0028] Both between the threaded stud 10 and the inner wall of the bottom box 2 and between the adsorption frame 7 and the suction guiding column 9 are fixed by welding.

[0029] The magnet 4 has a rectangular block structure.

[0030] As an explanation of the mounting structure of the circuit board 3, four mounting posts 12 arranged in a rectangle are provided on the front end face inside the bottom box 2. Threaded protrusions 13 are axially provided on the mounting posts 12. Hole positions matching the threaded protrusions 13 are provided at the four corners of the circuit board 3. Locking nuts 11 are screwed on the threaded protrusions 13; the circuit board 3 is lifted by the mounting posts 12 to avoid direct contact with the bottom box 2, which has a good heat dissipation effect. The hole positions at the four corners of the circuit board 3 are buckled with the corresponding threaded protrusions 13, and the locking nuts 11 are screwed in for fixation, and the operation is convenient.

[0031] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation to the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0032] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. can be used here to describe the spatial positional relationship of a device or feature shown in the figure with other devices or features. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figure for the device. For example, if the device in the attached drawing is inverted, the device described as "above" or "over" other devices or structures will then be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0033] In addition, it should be noted that the use of terms such as "first", "second" etc. to define components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, so they should not be construed as limiting the protection scope of the present utility model.

[0034] The above has introduced in detail a peripheral type up and down magnetic attraction elevator control box provided by the present application. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, based on the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
