Abstract

The invention provides a window breaking device for bus window breaking and escaping, which is characterized in that: the lever principle is utilized to reduce the force value required by a user to break the window, the best position of a broken glass point of the broken window is ensured through axial positioning, and the 45-degree included angle designed by the lever is utilized to ensure that the hammering direction of a firing pin is vertical to the surface of the glass window to be broken when the window is broken, so that the window breaking efficiency is improved. The invention comprises a cross bar fixed on a car window and a lever-shaped window breaker, wherein the lever-shaped window breaker is fixed on the cross bar through a broken-corner circular lantern ring, and the lantern ring is connected with a stress rod with a handle through a rotating shaft, so that the stress rod can rotate by taking the rotating shaft as a center and is changed from a contraction state parallel to the cross bar into a use state vertical to the cross bar. When the handle of the stress rod is pulled down, the firing direction of the firing pin at the head of the window breaker is vertical to the window surface, so that the window is broken. Meanwhile, the cross rod has a special section, so that the window breaking device can be taken down through translation after the window breaking step is completed and used for other purposes. The invention has the main characteristics of easy realization of the structure and low cost. Compared with the traditional window breaking mode, the window breaking efficiency, safety and reliability are higher.

Description

Window breaking device for bus escape

Technical Field

The invention relates to a window breaking device for bus escape, and belongs to the field of public traffic safety.

Background

The public transportation safety significance is great. In the face of sudden accidents of buses, particularly, the problem that the doors cannot be normally opened due to fire, dense smoke, mechanical deformation and the like is a primary task of how to ensure that passengers safely and quickly escape from the site. At present, a safety hammer with a configured foundation is taken as a main countermeasure on a bus, but the bus still has a plurality of problems in design and use, including confirmation of a correct hammering point position, a hammering direction, reasonable hammering force, a use mode and the like. The above problems all cause great potential safety hazards, and it cannot be guaranteed that the passengers can have enough strength and skill to successfully escape from the scene within a limited time to avoid danger when an accident occurs. As a public transportation safety facility, all possible user conditions must be considered so as to temporarily minimize casualties at risk.

Disclosure of Invention

The invention aims to provide a bus window breaking device which can automatically hammer, position, hammer and break a window and assist in escape.

In order to solve the technical problem, the invention provides a window breaking device for bus window breaking and escaping, which is characterized by comprising a cross rod assembly and a lever-shaped window breaker, wherein the cross rod assembly is connected with a frame; the transverse rod assembly is fixed on the window frame of the vehicle window and comprises a transverse rod main body, a transverse rod fixing piece and a fixing bolt, a notch is formed in one side of the rotary sleeve, the cross section of the transverse rod main body is matched with the notch of the rotary sleeve, the rotary sleeve can be detached through the notch when rotating to the short edge of the transverse rod main body, and meanwhile the lever-shaped window breaking device is relatively fixed in the length direction of the transverse rod main body.

Preferably, when the rotation angle of the rotary sleeve around the cross rod main body is 135 degrees, the direction of the pressing opening is vertical to the glass window.

Preferably, under the non-working state, the handle stress rod is parallel to the cross rod main body, the window breaker fixing piece is arranged on the cross rod main body and comprises a short bolt and a pushing piece, and under the working state, the pushing piece is pushed, the small bolt slides out of the cross rod main body, so that the handle stress rod can rotate to be vertical.

The invention has the advantages that:

1. the force required for breaking the window is saved by utilizing the lever principle, and the passenger with small force in the vehicle can also successfully and quickly break the window;

2. the lever-shaped window breaker is fixed at the position of the cross rod in the horizontal direction, so that the low window breaking efficiency caused by the deviation of a hammering position is avoided, and meanwhile, the lever-shaped window breaker can be detached for independent use after the window is successfully broken;

3. the window glass is broken after being used and then taken down for other purposes;

4. convenient to use, it is efficient. .

Detailed Description

In order to make the invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

Examples

As shown in fig. 1, the device is an overall schematic view at a head-up view, and comprises a cross bar assembly connected to a vehicle frame and a lever-shaped window breaker, wherein the lever-shaped window breaker is provided with a handle stress bar 106 and a handle fixing member 105, the handle stress bar 106 is connected to a rotating sleeve 108 through a rotating shaft, the front end of the handle stress bar 106 is a pressing opening 107, and a window breaking spring firing pin 109 is arranged in the pressing opening 107; the rail assembly is fixed to the window sash and includes a rail body 101, a rail mount 102, a fixing bolt 103, and a window breaker mount 104.

The device is directly installed on the bus body and is assembled with the bus body to leave a factory simultaneously, namely the rotary sleeve 108 is directly fixed on a window together with the cross rod assembly after being installed, and then the device is integrally put into use with the bus. The specific structure is explained below by way of explanation of the manner of use in practice.

First, as shown in fig. 1, the device is in the state under non-escape condition, i.e. the handle force-bearing rod 106 with handle is parallel to the cross-bar body 101 and fixed by the latch in the window breaker fixing member 104. In case of emergency escape, as shown in fig. 2, the window breaker fixing member 104 is pressed to push out the edges of the two small segments of the latches from the cross bar main body 101, so that the window breaker handle fixing member 105 can be separated from the latches and rotated to be perpendicular to the cross bar main body 101, as shown in fig. 5.

When the lever-shaped window breaker is rotated to be vertical to the cross bar main body 101, the lever-shaped window breaker can be used, passengers hold the handle of the lever-shaped window breaker to rotate around the cross bar main body 101 by taking the rotating sleeve 108 with the rotating shaft as a center, when the handle is rotated to 45 degrees, as shown in fig. 7, the pressing opening 107 is tightly attached to the window glass, and the window glass can be broken by ejecting the window breaking spring striker 109 under the pressure of the pressing opening 107.

After the glass is broken, the window breaker is continuously rotated, when the glass is rotated for 45 degrees again, the straight line where the handle stress rod 106 is located is parallel to the horizontal plane, and by means of the notch of the rotating sleeve 108 with the rotating shaft and the section shape of the cross rod main body 101, as shown in fig. 5 and 6, the lever-shaped window breaker can be horizontally moved and taken out, and the taken-out lever-shaped window breaker can be used as a hammer and is also a powerful tool for assisting escape.
