[0044] Example 1

[0045] This embodiment provides a specific implementation of the installation device. The installation device is used to install electrical appliances such as air purifiers and disinfection machines 3 on the elevator. The installation device includes an installation bracket 2, and the installation bracket 2 includes a first load-bearing structure and a second load-bearing structure.

[0046] Among them, the first load-bearing structure is adapted to be connected to the load-bearing structure of the elevator; the second load-bearing structure is adapted to be connected to the electrical appliance 3. The second load-bearing structure is lower than the first load-bearing structure, and the electrical appliance 3 is adapted to be installed above the second load-bearing structure. In this embodiment, the first load-bearing structure is adapted to be fixedly connected to the load-bearing structure of the elevator by means of bolts and nuts. Specifically, bolt holes are provided on the first load-bearing structure and the load-bearing structure. After the bolts pass through the bolt holes on the first load-bearing structure and the load-bearing structure, the nuts are tightened. In other alternative embodiments, the first load-bearing structure and the load-bearing structure are welded.

[0047] For the installation device provided in this embodiment, by setting the first load-bearing structure and the second load-bearing structure, the first load-bearing structure can be fixed on the load-bearing structure of the elevator, so that the entire installation bracket 2 is fixed on the load-bearing structure of the elevator. The second load-bearing structure is lower than the first load-bearing structure, thus providing sufficient installation space for the electrical appliance 3. This installation device can install electrical appliances such as air purifiers or disinfection machines 3 on the elevator.

[0048] Based on the above embodiment, in one embodiment, as Figures 1 to 5 shown, the installation device further includes a self-locking structure, and the electrical appliance 3 is adapted to be connected to the second load-bearing structure through the self-locking structure. It is convenient to fix the electrical appliance 3 to the second load-bearing structure, which is convenient for operation. At the same time, the number of fastening bolts used can be reduced, and the electrical appliance 3 can be easily installed on the installation bracket 2. In other alternative embodiments, the electrical appliance 3 is fixedly connected to the second load-bearing structure by bolts and nuts.

[0049] Based on the above embodiments, in one embodiment, the self-locking structure includes a connection hole structure and a connector 4. The connection hole structure is provided on the second bearing structure and includes a first through hole 221. The connector 4 is adapted to be provided on the electrical device 3. The connector 4 includes a first part 41 and a second part 42. On a projection plane perpendicular to the length extension direction of the connector 4, the projection of the second part 42 covers the projection of the first part 41, and the outer diameter of the second part 42 or the maximum distance between two side walls is greater than the aperture of the first through hole 221 or the minimum distance between two opposite hole walls. During installation, first fix the connector 4 on the electrical device 3 or the second bearing structure, insert the connector 4 into the first through hole 221. Since the outer diameter of the second part 42 or the maximum distance between two side walls is greater than the aperture of the first through hole 221 or the minimum distance between two opposite hole walls, then move the electrical device so that the second part 42 of the connector 4 is restricted at the lower end of the first through hole 221, and the connector 4 will not come out of the first through hole 221. Specifically, when the first through hole 221 is a round hole, the first part 41 of the connector 4 can be made of a rigid material, and the second part 42 can be made of an elastic material. During installation, by squeezing the second part 42 to make it pass through the first through hole 221, when the second part 42 passes through the first through hole 221, it returns to its original size under the action of elastic force, locking the connector 4 in the hole. When the first through hole 221 is a rectangular hole, the maximum distance between two opposite hole walls of the first through hole 221 can be greater than the maximum distance between two side walls of the second part 42, so that the second part 42 can be easily passed through the first through hole 221. Then, by rotating the electrical device 3, the connector 4 is driven to rotate in the first through hole 221, so that the positions of the two side walls with the maximum distance of the second part 42 correspond to the positions of the two hole walls with the minimum distance of the first through hole 221, so that the second part 42 of the connector 4 is restricted at the lower end of the first through hole 221. In other alternative embodiments, the connection hole structure can be provided on the electrical device 3, and the connector 4 can be fixedly provided on the second bearing structure.

[0050] As Figure 6 shown, the first through hole 221 is a strip-shaped hole, and the minimum distance between two hole walls of the first through hole 221 is the width of the strip-shaped hole.

[0051] On the basis of the above - mentioned embodiments, in one embodiment, the connection hole structure further includes a second through - hole 222 that is in through - connection with the first through - hole 221. The aperture of the second through - hole 222 or the minimum distance between two opposite hole walls is greater than the aperture of the first through - hole 221 or the minimum distance between two opposite hole walls, and the cross - sectional area of the second through - hole 222 is greater than the cross - sectional area of the second part 42. During installation, first fix the connecting member 4 on the electrical device 3 or the second bearing structure. First, make the connecting member 4 easily pass through the second through - hole 222, and then move the electrical device 3 to move the connecting member 4 into the first through - hole 221, so that the second part 42 of the connecting member 4 is restricted at the lower end of the first through - hole 221, and the connecting member 4 will not fall out of the first through - hole 221. In this embodiment, the connecting member 4 can be entirely made of a rigid material.

Specifically, rivet or weld the riveting nut to the bottom of the electrical device 3. The leg structure 6 is provided with a bolt through - hole for the bolt to pass through. The leg structure 6 and the electrical device 3 can also be fixedly connected by welding. In other alternative embodiments, when the connecting member 4 is fixedly connected to the second bearing structure, the connection hole structure is provided on the leg structure 6. The setting of the leg structure 6 does not require adding a connection hole structure or a connecting member 4 at the bottom of the air purifier or disinfection machine, which is convenient for setting the connection hole structure or the connecting member 4.

[0053] On the basis of the above - mentioned embodiments, in one embodiment, the leg structure 6 is made of U - shaped steel and includes a first side wall and a second side wall that are oppositely arranged.

The connecting member 4 further includes a third part 43 adapted to be fixedly connected in the installation hole. One end of the connecting member 4 is restricted in the installation hole, and one end is restricted outside the first through - hole 221, so the fixation of the connecting member 4 is relatively reliable.

[0055] Based on the above embodiments, in one embodiment, the inner diameter of the mounting hole gradually decreases from the end far from the connection hole structure to the end close to the connection hole structure, and the shape of the third part 43 is adapted to the mounting hole. The mating surface of the third part 43 and the mounting hole is a conical surface, and the frictional force of the conical surface where the third part 43 and the mounting hole cooperate locks the connecting member 4 in the shaft seat 5. The shaft seat 5, the connecting member 4, and the first through hole 221 cooperate with each other to lock the connecting member 4 in the first through hole 221. In other alternative embodiments, the diameter of the mounting hole is slightly larger than the outer diameter of the third part 43. After the third part 43 is installed in the mounting hole, a filling member is filled in the gap to firmly position the third part 43 in the mounting hole, where the filling member can be made of a flexible material or have a structure similar to a pin.
