Fixed type toughened glass crushing escape apparatus

Abstract

The invention discloses a fixed type toughened glass crushing escape apparatus which is fixed on a base on toughened glass and is provided with a through hole which is perpendicular to the surface ofthe toughened glass; a hard impact rod with a pointed end is arranged in the through hole; the tail end of the impact rod, which is far away from the surface of the toughened glass, is connected witha strike cap; a resetting mechanism is arranged between the base and the strike cap; and a protective sleeve is arranged outside the cylinder of the base. The invention provides the fixed escape apparatus which can quickly crush the toughened glass without finding in the process of escape, thereby greatly shortening the escape time; because a beating mode is adopted and the impact rod is perpendicular to the surface of the toughened glass, the impact force required for crushing the toughened glass is effectively reduced, the slipping phenomenon in the process of use is avoided, and the successratio of crushing the toughened glass by weak people in the process of escape is ensured; and the design of the protective sleeve can effectively avoid the deadweight loss caused by wrongly beating.The fixed toughened glass crushing escape apparatus is suitable for quick escape by crushing the toughened glass under the emergency condition.

Description

technical field [0001] The invention relates to an emergency escape device, in particular to a fixed tempered glass broken escape device which can conveniently break toughened glass in an emergency. Background technique [0002] At present, various types of safety hammers that can be used to break tempered glass windows for escape emerge in an endless stream. In addition to breaking glass to escape, many safety hammers also have functions such as lighting and cutting knives. For example: a utility model safety hammer whose notification number is CN201077443Y has the functions of hitting and cutting. It is difficult to find the safety hammer quickly, thus missing the short first escape time. Although the safety hammer is placed on the fixed frame on some buses, the safety hammer placed on the fixed frame is easy to lose, and people are in extreme situations. When tense and flustered, it is also difficult to quickly remove the safety hammer from the fixed frame, and because t...

For example: a utility model safety hammer whose notification number is CN201077443Y has the functions of hitting and cutting. It is difficult to find the safety hammer quickly, thus missing the short first escape time. Although the safety hammer is placed on the fixed frame on some buses, the safety hammer placed on the fixed frame is easy to lose, and people are in extreme situations. When tense and flustered, it is also difficult to quickly remove the safety hammer from the fixed frame, and because the existing safety hammers are all swung in use, the striking part of the safety hammer may hit the glass surface. Because the hitting direction is not perpendicular to the glass surface, slipping occurs, which delays precious escape time. In addition, because the quality of the safety hammer is not large, the force required for swinging is relatively large, and it is difficult for the elderly, children and other infirm shatter the glass quickly

Although some energy storage type safety hammer escape devices have also been reported, because the probability of using the escape device is very low, after long-term storage, the escape device may fail due to the gradual loss of stored energy. It is usually triggered once, so once it is invalid, it cannot be used again
