Description

Fix quick broken window device on passenger train glass window

Technical Field

The utility model relates to a broken window ware technical field, concretely relates to fix quick broken window device on passenger train glass window.

Background

Common tools for bus and passenger train tourism traffic. In order to enable the existing buses and buses to run on highways more quickly, a whole piece of toughened window glass is mostly adopted. During the long-distance running process of the vehicle, some accidents inevitably happen. Under the condition that the vehicle burns in the carriage or the vehicle overturns, passengers in the carriage often need to save themselves in the first time, break window glass and open an outward escape passage. In order to facilitate escape in emergency, the existing passenger car is provided with a window breaker, and the window breaker can be used for breaking window glass to realize escape in emergency. When an accident occurs, a passenger firstly needs to find the window breaker and can break the automobile window only by a correct window breaking method, under the condition of nervousness, the passenger not only needs to quickly take the window breaker but also needs to be correctly used, certain difficulty exists, once the window breaker falls off in knocking, the consequence is unimaginable, precious time is delayed, and the passenger even possibly loses the escape opportunity. The window breaker of the existing passenger car has the defect of insufficient operation convenience. In order to overcome the defects of the conventional window breaking device, various window breaking device schemes are provided for numerous patents. For example, the authorized bulletin numbers CN105999572A "a multifunctional automobile window breaker", CN206566367U "a window breaker and a window breaker using the window breaker" and the like, these window breakers provide beneficial tools for emergency escape when a bus is in an accident, but they have a common defect that a window breaker needs to be found when a danger comes, and because the provided window breaker is small and exquisite, if the force is insufficient or the method is not enough, it is difficult to break the toughened glass to realize escape and self rescue, especially when the vehicle is turned over at ninety degrees, passengers are difficult to take the window breaker, and even if the window breaker is taken, the toughened glass on the top cannot be knocked by the window breaker at all.

However, in the patent of CN206644777U "sliding type bus window breaking device", although compared with the common window breaking device, the biggest difference is that a row of sliding rails is respectively arranged on both sides of the window, so that the window breaking device which can be originally fixed on one corner of the window can slide in the sliding rails, thereby the position of the window breaking device for breaking the window is greatly increased, when a fire occurs, a driver can control the window breaking device to respectively hit the window at different positions of the window, and the window breaking and the disintegration are accelerated. This patent need not the broken window of manpower, and control is convenient, and degree of automation is high, but the structure is complicated, and is with high costs, and if the very first time of car accident destroys automatic control system, then all passengers can't save oneself and flee.
