Door closer or temperature control slide rail of door closer

Abstract

The invention relates to a door closer or a temperature control slide rail of the door closer. A slide rail body and a sliding block assembly are included; the sliding block assembly is arranged in the slide rail body in a sliding manner; a temperature control unlocking stopping and fixing device is further arranged in the slide rail body, and comprises a fixed base, a rocking rod, an unlocking sliding base, a temperature controller and an elastic piece; the fixed base is fixedly arranged in the slide rail body; the rocking rod is arranged on the fixed base in a swinging manner; one end of therocking rod is provided with a lock hook used for being matched with the sliding block assembly; the other end of the rocking rod is matched with a bevel of the unlocking sliding base; the unlockingsliding base is arranged in the slide rail body; and the temperature controller and the elastic piece are arranged between the fixed base and the unlocking sliding base. The temperature control unlocking stopping and fixing device has the effect of locking the sliding block assembly; meanwhile, the temperature control unlocking stopping and fixing device has the effect of performing automatic unlocking on the sliding block assembly when a fire disaster happens; the temperature controller of the temperature control unlocking stopping and fixing device is arranged between the fixed base and theunlocking sliding base due to elastic force of the elastic piece, so that the volume and the length of the temperature control unlocking stopping and fixing device are small, and the temperature control unlocking stopping and fixing device is suitable for being used on a small-width door window.

Description

technical field [0001] The invention relates to a slide rail for a door closer or a window closer, in particular to a temperature control slide rail for a door closer or a window closer.

Problems solved by technology

In this structure, the locking mechanism and the unlocking mechanism are set separately, and its length is relatively large, which is not conducive to the use of windows with narrow width.

Moreover, the structure of the unlocking mechanism is complicated and the cost is relatively high
