As an improvement of the above solution, the surface of the telescopic plate is provided with a plurality of protrusions.

A dust-proof elevator includes the above-mentioned elevator dust-proof device, a car and a shaft, and a dust-proof button is arranged in the car, and the dust-proof button is connected with a controller of the elevator. Implementing the utility model has the following beneficial effects:

1. An elevator dust-proof device provided by the utility model includes a telescopic plate, a motor, and two sets of slide rail assemblies. The two sets of slide rail assemblies are respectively arranged on both sides of the bottom of the car. Between the two groups of slide rail assemblies, the two groups of slide rail assemblies are connected to the motor, and the motor is connected to the controller of the elevator. The distance between the two groups of slide rail assemblies is less than or equal to the opening width of the landing door. The motor-driven slide rail assembly precesses and slides linearly, so that the telescopic plate protrudes from the bottom of the car and covers the first and second gaps, thereby preventing dust and sand from falling into the first and second gaps , reduce elevator failure.

2. The utility model provides a dust-proof device for elevators. The surface of the telescopic plate is provided with a plurality of protrusions to increase the anti-skid property of the telescopic plate and avoid slipping of passengers or goods transported.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings.

As shown in FIG. 1 to FIG. 2 , an elevator dustproof device provided in this embodiment includes a telescopic plate 3 , a motor 4 , and two sets of slide rail assemblies 5 . The two sets of slide rail assemblies 5 are respectively arranged on both sides of the bottom of the car 2 , and the telescopic plate 3 is installed between the two sets of slide rail assemblies 5 . Specifically, the slide rail assembly 5 includes a linear slide rail 51 and a slider 52 . The linear slide rail 51 is installed on the bottom of the car 2 through screw connection, and the telescopic plate 3 is installed on the slider 52 through screw connection. In other embodiments of the present application, the connection method between the linear slide rail and the bottom of the car, and the connection method between the telescopic plate and the slider may also be welding, but is not limited thereto.

The two groups of slide rail assemblies 5 are connected to the motor 4, and the motor 4 is connected to a controller (not shown in the figure) of the elevator. Specifically, there is an electrical connection between the slide rail assembly and the motor, and a signal connection between the motor and the controller of the elevator. The motor 4 drives the slider 52 to precess and linearly slide along the linear slide rail 51, so that the telescopic plate 3 protrudes from the bottom of the car 2 and covers the first gap 11 and the second gap 12, thereby preventing dust and sand Stones fall in the first and second cracks, reducing elevator breakdowns. Preferably, the distance between the two sets of slide rail assemblies is less than or equal to the opening width of the landing door.

Specifically, the expansion plate is a steel plate, which has strong rigidity and can be made into a thin plate with a small thickness. Since the expansion plate needs to be installed at the bottom of the car, the steel plate is beneficial to save space and reduce the overall gravity of the car. In other embodiments of the present application, the telescopic board may also be a PVC board, a carbon fiber board, or the like. The thickness of the telescopic plate is 0.1-1 cm. The longitudinal length of the telescopic plate is smaller than the longitudinal length of the car. More preferably, the surface of the telescopic board is provided with a plurality of protrusions to increase the anti-skid property of the telescopic board and prevent people or goods being transported from slipping.

The utility model also provides a dust-proof elevator, which comprises the above-mentioned elevator dust-proof device, a car and a shaft. The car is provided with a dust-proof button, and the dust-proof button is connected with the controller of the elevator.

As shown in Figure 3, described elevator dust-proof device 3 is arranged on the bottom of car 2, and described dust-proof button 6 is arranged on the top of the floor button of car 2, and described dust-proof button 6 is connected with the controller of elevator ( not shown) have signal connections.

The working principle of the dust-proof elevator described in the utility model: when a passenger needs to transport sand, gravel, soil and other items, the passenger presses the dust-proof button, and the controller with signal connection with the dust-proof button is electrically connected with the motor, and the motor Working, drive the slider to precess and slide linearly along the linear slide rail, so that the telescopic plate protrudes from the bottom of the car and covers the first gap and the second gap, thereby preventing dust, sand and gravel from falling in the first gap and the second gap In the second gap, reduce elevator failure.

The above is a preferred embodiment of the present utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, some improvements and modifications can also be made, these improvements and modifications It is also regarded as the protection scope of the present utility model.
