Description

Magnetic protective device and elevator door using the magnetic protective device

The invention relates to the surrounding structure of an automatic door of an elevator system, especially a magnetic protection device that can make the closing action of the door panels have a safety gap when the automatic door of the elevator system is closed, and the elevator door using the magnetic protection device.

Car cage elevator system is the most common vertical lift system at present. It is equipped with various safety protection facilities and devices for carrying people, such as anti-pinch devices, elevator air-conditioning devices and emergency call devices, etc., which have been widely developed and applied. .

Because the components of the traditional cage-type elevator system are quite complex, elevator developers must conduct elevator operation tests to ensure that the elevator system is normal before the elevator system is assembled and put into operation, or when the elevator is running for a long time for maintenance. During the elevator operation test mentioned above, it is often necessary to adjust the closing action of the elevator door to ensure that the gap when the elevator door is closed is within a certain standard. Otherwise, if the gap is too large, the closure will be incomplete and prone to danger. Mechanical damage will reduce the life of the elevator system. However, due to the complex components of the traditional elevator system, it often takes a lot of manpower and time to adjust the clearance of the elevator door. In other words, there is still room for improvement in the conventional way of adjusting the closing gap of the elevator door.

The purpose of this creation is to provide a magnetic protection device for the elevator door, which helps to adjust the closing gap of the elevator door.

In order to achieve the above creation purpose, this creation provides a magnetic protection device for elevator doors. The elevator door includes a frame, a left door panel and a right door panel. The left and right door panels are slidably set on the frame, and The magnetic protection device is used to be fixed between the tops of the left and right door panels and includes a left magnetic component and a right magnetic component. The left magnetic component has a first fixing part and a first magnetic part fixed on the first fixing part, and the first fixing part is used to be slidably fixed on the top of the left door panel; the right magnetic component has A second fixing part and a second magnetic part fixed on the second fixing part and magnetically attracting or repelling the first magnetic part, the second fixing part is used to be slidably fixed on the right door panel The top of the second magnetic piece is spaced opposite to the first magnetic piece.

With the above-mentioned technical features, when the elevator door test machine is tested, the positions of the first and second fixing parts of the magnetic protection device can be adjusted according to the gap between the door panels, and the first magnetic part and the second magnetic part can be arranged. components to make them magnetically attract or magnetically repel each other, and then control the closed gap between the left and right door panels in detail, so that there is no need to additionally replace the elevator door or use other more complicated components to control the left and right doors of the elevator The closing gap between the panels can be adjusted quickly to achieve the purpose of quickly adjusting the closing gap of the door panels.

Preferably, the first and second fixing parts have a first and a second elongated slot respectively, and the first fixing part is fixed on the first elongated slot by a first fixing bolt passing through the first elongated slot The top of the left door panel, and the second fixing part is fixed on the top of the right door panel through the second elongated slot hole by a second fixing bolt. Through the cooperation of the first and second fixing bolts with the first and second slotted holes, the position of the first and second fixing parts locked on the top of the left and right door panels can be easily slid and adjusted, thereby adjusting the second 1. The distance between the two magnetic parts. In this way, only by adjusting the first and second The position of the fixing part can be adjusted in a relatively simple way to control the closing gap of the elevator door without additionally adjusting other more complex components of the elevator door.

Preferably, the first fixing part includes a first base plate fixed on the top of the left door panel and a first side plate vertically connected to the first base plate, and the second fixing part includes a first side plate fixed on the right door A second base plate on the top of the plate and a second side plate vertically connected to the second base plate. Wherein the first and second substrates respectively have the first elongated slot and the second elongated slot, the first magnetic part is fixed on the first side plate, and the second magnetic part is fixed on the second side panels. In this way, the magnetic protection device can be easily replaced and the gap between the first and second magnetic elements can be adjusted.

Another purpose of this creation is to provide an elevator door using the above-mentioned magnetic protection device, which can be adjusted by adjusting the relative position between the first and second fixing parts (that is, adjusting the gap between the first and second magnetic elements). Easily adjust the closing gap between the left and right door panels of the elevator door.

Preferably, the elevator door has a first guide pin and a second guide pin, the first guide pin passes through the first elongated slot hole of the first fixing member, and the second guide pin passing through the second elongated slot of the second fixing member. Through the cooperation of the first and second fixing bolts with the first and second slotted holes and the guiding and positioning of the first and second guide pins, the first and second fixing parts can be easily slid and adjusted to be locked on the The position of the top of the left and right door panels, and when the first and second fixing parts slide, the first and second magnetic parts can still be kept aligned with each other to ensure that the first and second magnetic parts can function normally. In this way, it can be ensured that the closing gap of the elevator door can be adjusted correctly, and the efficiency of test run and maintenance of the elevator system can be greatly improved.
