Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and particularly to a structure for improving the maintenance efficiency of elevator light-transmitting plates. Background Art

[0002] With the diversity of ceiling lamp types, the light-emitting surface is getting larger and larger. With the popularization of the styles of large-sized surface light sources, a large amount of time-consuming problems have emerged. Therefore, the design requirements for the light-transmitting plate structure are getting higher and higher. A series of problems such as safety, fire resistance, maintenance and cleaning, and lamp replacement need to be solved and optimized.

[0003] There are two traditional maintenance methods for large-area light-transmitting plates: The first method is to remove the entire lower ceiling inside the car. The light-transmitting plate can be directly cleaned without being removed, and the lamps are generally locked on the upper ceiling and can also be directly replaced. This maintenance method is time-consuming and laborious, and cannot be operated by a single maintenance personnel. The second method is to lift and tilt the light-transmitting plate inside the car and then take it out. After the light-transmitting plate is taken out, it can be cleaned, and the lamps fixed on the top can be replaced. The disadvantage of this method is that the fixing method of the light-transmitting plate is defective. First of all, the conventional double-sided adhesive fixing method can only solve the fixing during new product shipment. Once maintained multiple times, the double-sided adhesive fails, which is likely to cause safety risks. Using the gourd hole buckle method, it is very difficult to take out the light-transmitting plate and align the holes, and both the disassembly and restoration are extremely time-consuming. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a structure for improving the maintenance efficiency of elevator light-transmitting plates in view of the above technical problems existing in the traditional maintenance methods for large-area light-transmitting plates. It can realize the function of switching between the fixing and opening of the light-transmitting plate, and enable the maintenance personnel to open the auxiliary structure with one hand and without tools inside the car, so as to realize the cleaning of the light-transmitting plate and the maintenance of the lamps.

[0005] The technical problem to be solved by the present invention can be achieved through the following technical solutions:

[0006] A structure for improving the maintenance efficiency of elevator light-transmitting plates, including a car upper ceiling and a light-transmitting plate, characterized in that it further includes: a plurality of sets of elastic magnetic adsorption units. The light-transmitting plate is installed on the car upper ceiling through a plurality of sets of elastic magnetic adsorption units. After the plurality of sets of elastic magnetic adsorption units are magnetically adsorbed, the light-transmitting plate is adsorbed on the car upper ceiling. After the plurality of sets of elastic magnetic adsorption units are magnetically desorbed, the light-transmitting plate can be removed from the car upper ceiling.

[0007] In a preferred embodiment of the present invention, there are two sets of the elastic magnetic adsorption units, which are respectively arranged at the ends of the opposite ends of the light-transmitting plate.

[0008] In a preferred embodiment of the present invention, each set of elastic magnetic adsorption units includes:

[0009] A first magnet mounted on the back of the light-transmitting plate;

[0010] A sliding plate slidably arranged on the ceiling of the car, wherein the sliding plate can reciprocate between an adsorption position and a desorption position in a direction parallel to the plate surface of the light-transmitting plate under the action of an external force;

[0011] A second magnet is mounted on the sliding plate, and the second magnet has opposite magnetic properties to the first magnet; when the sliding plate moves to an adsorption position, the second magnet is adsorbed together with the first magnet, so that the light-transmitting plate is adsorbed on the ceiling of the car; when the sliding plate moves to a desorption position, the second magnet is offset from the first magnet by one position and is desorbed;

[0012] A spring is arranged between the light-transmitting plate and the sliding plate. When the sliding plate moves to an adsorption position, the spring is compressed so that the second magnet is adsorbed together with the first magnet, and the light-transmitting plate is adsorbed on the ceiling of the car. When the sliding plate moves to a desorption position, the spring is released to push the light-transmitting plate away from the adsorption position.

[0013] In a preferred embodiment of the present invention, each set of elastic magnetic adsorption units also includes a spring seat fixed to the end of the light-transmitting plate, the lower part of the spring is installed on the spring seat, and the upper part of the spring acts on the sliding plate.

[0014] In a preferred embodiment of the present invention, a space for inserting the spring seat is provided at the end of the sliding plate away from the end of the light-transmitting plate; when the sliding plate moves to the adsorption position, after the spring seat is inserted into the space, the spring seat is placed on the sliding plate and cooperates with the sliding plate to compress the spring; when the sliding plate moves to the desorption position, the spring seat withdraws from the space, the spring is released, and the light-transmitting plate is pushed away from the adsorption position.

[0015] In a preferred embodiment of the present invention, the second magnet is mounted on a limit baffle, and the limit baffle is mounted on the sliding plate, so that the second magnet and the limit baffle move together with the sliding plate.

[0016] In a preferred embodiment of the present invention, a retreat space is provided between the upper ceiling and the light-transmitting plate and the limit baffle and the second magnet. When the sliding plate moves to the desorption position, the limit baffle and the second magnet enter the retreat space, so that the second magnet is desorbed from the first magnet.

[0017] In a preferred embodiment of the present invention, a rubber pressing head is installed at one end of the sliding plate close to the end of the light-transmitting plate, and the rubber pressing head plays a buffering role in adsorbing the light-transmitting plate to the upper ceiling of the car.

[0018] Due to the above technical solution, the present invention adopts the principle methods of spring pressing, sliding and magnetic adsorption to realize the function of switching between the fixation and opening of the light-transmitting plate. This structure allows maintenance personnel to open the elastic magnetic adsorption unit with one hand inside the car without tools, thereby realizing the cleaning of the light-transmitting plate and the maintenance of the lamps. The specific method is to slide the sliding plate towards the side plate by pressing the sliding plate. When the sliding plate cannot slide anymore, it means that the clamping part has completely detached from the adsorption of the light-transmitting plate. At this time, the light-transmitting plate can be opened and maintained. After the maintenance is completed, press the sliding plate and push it towards the ceiling. When the hand feels the suction force, the first magnet and the second magnet will automatically adsorb, thus realizing the restoration work of the light-transmitting plate, and the light-transmitting plate is fixed again.

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Refer to Figures 1 to 4 , a structure for improving the maintenance efficiency of the elevator light-transmitting plate shown in the figure, includes the upper ceiling 100 of the car and the light-transmitting plate 200.

[0025] The characteristics of the present invention are: it further includes several sets of elastic magnetic adsorption units 300, and the light-transmitting plate 200 is adsorbed and installed on the upper ceiling 300 of the car through several sets of elastic magnetic adsorption units 300. After several sets of elastic magnetic adsorption units 300 are magnetically adsorbed, the light-transmitting plate 200 is adsorbed on the upper ceiling 100 of the car. After several sets of elastic magnetic adsorption units 300 are magnetically desorbed, the light-transmitting plate 200 can be removed from the upper ceiling 100 of the car.

[0026] Generally speaking, there are two sets of elastic magnetic adsorption units 300, which are respectively arranged at the ends of the opposite ends of the light-transmitting plate 200. However, it is not limited to two sets, and there can be multiple sets according to needs, which are installed at different ends of the light-transmitting plate 200.

[0027] Each set of elastic magnetic adsorption units 300 includes: a magnet 310 (the aforementioned first magnet), a magnet 320 (the aforementioned second magnet), a sliding plate 330, a spring 340, a spring seat 350, a limit baffle 360, and a rubber pressing head 370. The magnet 320 has the opposite magnetism to the magnet 310.

[0028] The magnet 310 is installed at the end position of the light-transmitting plate 200. The sliding plate 330 is slidably arranged on the upper ceiling 100 of the car and can reciprocate between the adsorption position and the desorption position in a direction parallel to the plate surface of the light-transmitting plate 200 under the action of an external force.

[0029] The limit baffle 360 is installed on the sliding plate 330, and the magnet 320 is installed on the limit baffle 360 so that the magnet 320 and the limit baffle 360 move together with the sliding plate 330. In this way, when the sliding plate 330 moves to the adsorption position (the right side of the drawing paper), the magnet 320 adsorbs together with the magnet 310, so that the light-transmitting plate 200 is adsorbed on the upper ceiling 100 of the car; when the sliding plate 330 moves to the desorption position (the left side of the drawing paper), the magnet 320 and the magnet 310 are staggered by a position and the adsorption is released.

[0030] The shape of the spring seat 350 is L-shaped. The vertical side of the spring seat 350 is fixedly installed at the end position of the light-transmitting plate 200, and the bottom of the spring 340 is installed on the horizontal side of the spring seat 350.

[0031] A space 331 for inserting the horizontal side of the spring seat 350 and the spring 340 is provided at the end of the sliding plate 330 far from the end of the light-transmitting plate 200. The space 331 has a top edge 331a, a bottom edge 331b, and an end edge 221a. The opening of the space 331 faces the horizontal side of the spring seat 350. In addition, a handle 332 is provided at the end of the sliding plate 330 far from the end of the light-transmitting plate 200. By pulling the handle 332 by hand, the sliding plate 330 can be driven to slide.

[0032] When the sliding plate 330 is pushed to the adsorption position through the handle 332, the horizontal side of the spring seat 350 is inserted into the space 331. The horizontal side of the spring seat 350 is placed on the bottom edge 331b and cooperates with the top edge 331a to compress the spring 340; when the sliding plate 330 is pushed to the desorption position through the handle 332, the horizontal side of the spring seat 350 withdraws from the space 331, and the spring 340 loses the restriction of the top edge 331a and is released. The released spring 340 pushes the light-transmitting plate 200 away from the adsorption position through the horizontal side of the spring seat 350.

[0033] In addition, in order to enable the limit baffle 360 and the magnet 320 to yield relative to the upper ceiling 100 of the car, a yielding space 400 is provided between the upper ceiling 100 and the light-transmitting plate 200 and the limit baffle 360 and the magnet 320. When the sliding plate 330 moves to the desorption position, the limit baffle 360 and the magnet 320 enter the yielding space 400, so that the magnet 320 is desorbed from the magnet 310.

[0034] In order to enable the light-transmitting plate 200 to have a buffering effect during adsorption to prevent it from being damaged by impact, a rubber pressing head 370 is installed at one end of the sliding plate 330 close to the end of the light-transmitting plate 200. The rubber pressing head 370 plays a buffering role in adsorbing the light-transmitting plate 200 to the upper ceiling 100 of the car, and it is not easy for the edge to break due to over-tight locking or impact on the light-transmitting plate 200.

[0035] A light-transmitting blank surface 210 is provided on the plate surface of the light-transmitting plate 200 to allow light to pass through.
