Detailed Description of the Preferred Embodiments

[0034] Hereinafter, exemplary embodiments of the present utility model will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present utility model can be more thoroughly understood and the scope of the present utility model can be completely conveyed to those skilled in the art.

[0035] As Figures 1 to 5 shown, an embodiment of the present utility model provides an elevator car lighting device that is easy to disassemble and assemble, including: a car top 1; a mounting mechanism 2 provided on the surface of the car top 1 for disassembling and installing lighting equipment; and a cleaning mechanism 3 provided on the lower surface of the car top 1 for cleaning the surface of the lighting equipment.

[0036] As Figures 1 to 4As shown in the figure, the installation mechanism 2 includes four limiting slots 201 which are opened on the surface of the car top 1. The four limiting slots 201 are divided into two groups in pairs. The inner wall of the limiting slot 201 is provided with a limiting hole 202. A hanging ear 205 is slidably connected to the inner wall of the limiting slot 201. A lighting fixture 204 is fixedly connected to the surface of the hanging ear 205. Two rectangular slots 203 are opened on the surface of the car top 1. Two limiting rods 206 are slidably connected to the inner wall of the rectangular slot 203. The size of the limiting rod 206 is adapted to the size of the limiting hole 202. When it is necessary to disassemble and assemble the lighting fixture 204, the four hanging ears 205 fixedly connected to the lighting fixture 204 are engaged with the limiting slots 201, and then the four limiting rods 206 in the two rectangular slots 203 of the car top 1 are slid so that they are engaged with the corresponding four limiting holes 202, thereby achieving the effect of fixing the lighting fixture 204 to the car top 1. When it is necessary to disassemble, separate the four limiting rods 206 from the four limiting holes 202, and the lighting fixture 204 can be removed.

[0037] As Figures 1 to 4 shown, one end of each of the two limiting rods 206 is fixedly connected with a vertical plate 207. When the limiting rod 206 is slid, the presence of the vertical plate 207 facilitates pushing and pulling the limiting rod 206 to be engaged with the limiting hole 202.

[0038] As Figures 1 to 4 shown, a spring 208 is fixedly connected to the surfaces of the two vertical plates 207 close to each other. The setting of the spring 208 increases the stability between the lighting fixture 204 and the car top 1.

[0039] As Figures 1 to 4 shown, a square slot 209 is opened on the surface of the vertical plate 207. A rotating rod 210 is rotatably connected to the inner wall of the square slot 209. A magnet 211 is fixedly connected to the surface of the rotating rod 210. When the limiting rod 206 is engaged with the limiting hole 202 under the action of the spring 208, the cooperation of the two rotating rods 210 and the two magnets 211 avoids the situation that the spring 208 is squeezed by an external force and the limiting rod 206 is disengaged from the limiting hole 202.

[0040] In the embodiment of the present utility model (working principle), by providing the installation mechanism 2, when it is necessary to install the lighting fixture 204, the two groups of vertical plates 207 are used to squeeze the spring 208. At this time, the four hanging ears 205 around the lighting fixture 204 are engaged with the limiting slots 201 of the car top 1. Release the two groups of vertical plates 207, and the limiting rods 206 are engaged into the limiting holes 202. Subsequently, rotate the rotating rods 210 on the surfaces of the vertical plates 207. Under the action of the magnets 211 on their surfaces, the magnetic attraction causes the four rotating rods 210 to be connected in pairs, achieving the effect of quickly installing the lighting equipment.

[0041] As Figure 1 and Figure 5As shown in the figure, the cleaning mechanism 3 includes two fixing plates 31 which are fixedly connected to the surface of the car top 1. A screw 32 is rotatably connected to the surface of the fixing plate 31. A motor 33 is fixedly connected to the surface of the fixing plate 31. The output end of the motor 33 is fixedly connected to the screw 32. A cleaning block 34 is threadedly connected to the arc surface of the screw 32. When the lower surface of the lighting fixture 204 needs to be cleaned, the motor 33 is started, and the cleaning block 34 is driven by the screw 32 to perform a reciprocating rotational motion, thereby achieving the effect of scraping the dust on the lower surface of the lighting fixture 204. After the cleaning is completed, the motor 33 is turned off. Since the cleaning is more convenient, the cleaning efficiency is indirectly improved.

[0042] As Figure 1 and Figure 5 shown in the figure, a rectangular plate 35 is fixedly connected to the surface of the car top 1. A chute 36 is formed on the surface of the rectangular plate 35. A slider 37 is slidably connected to the inner wall of the chute 36. The slider 37 is fixedly connected to the cleaning block 34. When the screw 32 drives the cleaning block 34 to perform a reciprocating rotational motion, the slider 37 in the chute 36 on the surface of the rectangular plate 35 also moves accordingly. With the cooperation of the slider 37 and the chute 36, the moving direction of the cleaning block 34 is restricted.

[0043] As Figure 1 and Figure 5 shown in the figure, several rollers 38 are rotatably connected to the inner wall of the chute 36. When the slider 37 slides in the chute 36, the existence of the rollers 38 greatly reduces the friction between the slider 37 and the inner wall of the chute 36, making the movement of the slider 37 easier and smoother, and at the same time reducing the wear of the parts.

[0044] In the embodiment of the present utility model, by setting the cleaning mechanism 3, when the lower surface of the lighting fixture 204 needs to be cleaned, the motor 33 is started, and the screw 32 drives the cleaning block 34 on its arc surface to move. At this time, the slider 37 also moves in the chute 36 on the surface of the rectangular plate 35. With the cooperation of the rollers 38, the friction between the slider 37 and the chute 36 is reduced, the service life of the parts is extended, and the effect of quickly cleaning the lower surface of the lighting fixture 204 is achieved.

[0045] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle described in the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
