Abstract

The utility model discloses a security window of elevator, which comprises a sliding guide mounted on the top of the carcase and a slide on the security window. The slide is arranged on the sliding guide and can sling on the sliding guide. The security window is a side-open type window, which does not need extra room on the top of the carcase to open the window. At the same time, a lock hook and a fixed hooker are one part of the electric inter-locking loop. The electric safe inter-locking loop is turned on just after the security window is closed and the lock hoop is connected with the fixed hooker. If the security window is opened, the electric safe inter-locking loop is turned off. All the above mentioned avoids the security window being crushed, when opening the window, and makes the electric inter-locking loop being safety and reliable.

Description

A kind of elevator safety window

(1) technical field

The utility model relates to a kind of elevator parts, particularly a kind of elevator safety window that is used for lift car.

(2) background technology

The security window that is used for lift car at present all adopts eversion type or turns up collapsiblely, and when this security window was opened, it was big to take up room, and exceeds the car top board easily, dangerous, or is damaged by pressure in use, and its electrical interlocks is also unreliable.

(3) summary of the invention

The technical problems to be solved in the utility model is: a kind of elevator safety window is provided, makes it not take sedan-chair top exceptional space fully when opening, damaged by pressure when avoiding using.

In order to solve the problems of the technologies described above, the utility model comprises and slides guide rail and security window slide plate, slides guide rail and is fixed on the car top board, and the security window slide plate slidably is provided with and slides on the guide rail.

In order to improve safety, include the locking device of security window slide plate and car locking, described locking device comprises fixed hook, latch hook and lock, fixed hook is fixed on the car top board, lock is arranged on the security window slide plate, latch hook is connected with the lock core of lock, and the rotation of lock core can make latch hook and fixed hook closing.

In order to make electrical interlocks safer, described latch hook and fixed hook are connected in the electrical interlocks loop.

The beneficial effects of the utility model are: the security window device in the utility model adopts laterally opened, does not take the car roof exceptional space when opening fully; Simultaneously, latch hook and fixed hook are the part in electrical interlocks loop, have only security window to close, and latch hook and fixed hook could be connected the chain loop of security window electrical safety fully after closing, and open security window, and the chain loop of this electrical safety also disconnects thereupon.Like this, both made to make it be difficult for being damaged by pressure when security window is opened, made again that electrical interlocks was more safe and reliable simultaneously.
