Abstract

The utility model relates to a striker impact type window breaking device, which is characterized in that: it comprises a column, a spring is set outside the column, a hollow shell is set outside the spring, the end of the spring is fixedly connected with the inner wall of the shell, and the top of the shell A striker is provided, a card slot is provided on the shell, and a hook switch is provided on the column. The hook switch includes an engaging part matched with the card slot and an operating part for operation. There is a pre-tightening device for pulling down the shell. After the shell is pulled down to the position, the spring is compressed and the engaging part is stuck in the slot. The column is also provided with a fixing device for detachable installation on the window. The utility model has the advantages of: simple and compact structure, light volume, easy to carry; convenient and labor-saving, a relatively small force can generate a large pre-tightening force, so that the window can be easily broken; reliable performance, suitable for use in a narrow space environment Still works reliably; works with a wide variety of forms, regardless of form shape.

Description

A kind of striker impact type is broken the window device

Technical field

The utility model relates to the device that a kind of forms of the vehicle for having closed in spaces break up.

Background technology

In today that the vehicle with closed in spaces develop rapidly, although it is comfortable and convenient to have brought for people's life, in a single day this vehicle are immersed in the water or during accident, tend to cause car door to open.And the forms of the vehicle generally all are the glass through strengthening, and conventional means is difficult to break, and therefore, people tend to miss brokenly the chance of window escape.Although the vehicle window next door at closed in spaces often is placed with brokenly the devices such as safety hammer that window is used.Although this device can play brokenly the effect of window, when in a single day the passenger runs into drowned or traffic accident, often nervous, be difficult for putting to good use arm space, also should not use strength, use traditional broken window instrument not too easily to break glass into pieces, thereby miss the escape best opportunity.

Summary of the invention

The purpose of this utility model provides the broken window device that a kind of user of allowing can smash vehicle forms easily.

In order to achieve the above object, the technical solution of the utility model has provided the broken window device of a kind of striker impact type, it is characterized in that: comprise column, outside column, be arranged with spring, the casing of hollow is located at outside the spring, captive joint with outer casing inner wall in the end of spring, top at shell is provided with striker, be provided with draw-in groove at shell, be provided with the snap fit switch at column, the snap fit switch comprises the engagement section that cooperates with draw-in groove and the operating portion that is used for operation, part below column is positioned at shell is provided with for the pre-tightening apparatus that shell is drop-down, shell is drop-down put in place after, the compressed while engagement section of spring is stuck in the draw-in groove, at the anchor fitting that also is provided with on the column to be removably mounted on the forms.

Preferably, described pre-tightening apparatus comprises the first fixed mount that is positioned at described shell below, the first fixed mount is located on the described column, uniform at least two handles around the first fixed mount, one end and first fixed mount of handle are hinged, the other end is hinged on the middle part of connecting rod separately, and the end of connecting rod and described shell are hinged, and the two ends of pull back spring connect respectively each self-corresponding handle and the first fixed mount links to each other.

Preferably, described anchor fitting comprises at least two supports that are distributed on around the described column, and the bottom of support and the second fixed mount are hinged, are provided be used to the rubber pad that is adsorbed on the forms on the top of support.

Preferably, outside described striker, be arranged with safety cap.

Compared with prior art, the utlity model has following beneficial effect:

1, simple and compact for structure, lightweight and portable in volume is easy to carry;

2, convenient and strength-saving, less power can produce larger predetermincd tension, thereby can break up easily forms;

3, dependable performance still can be worked under the space-constrained environment reliably;

4, be applicable to various forms, be not subjected to the restriction of forms shape.

Description of drawings

A kind of striker impact type that Fig. 1 provides for the utility model is broken the structural representation of window device.

The specific embodiment

For the utility model is become apparent, hereby with preferred embodiment, and cooperate accompanying drawing to be described in detail below.

As shown in Figure 1, be the broken window apparatus structure schematic diagram of a kind of striker impact type, the broken window device of described striker impact type comprises a column 2, and spring 10 is enclosed within on the column 1, and the shell 7 of hollow is enclosed within outside the spring 10 again, and shell 7 bottoms are top circle platform 5.One end and the column 1 of spring 10 are fixed, and the top inner wall of the other end and shell 7 is fixed.The fixed striker 8 in shell 7 tops, safety cap 9 of striker 8 overcoats.The draw-in groove 6 that a rectangle is arranged at shell 7 then has a snap fit switch 3 on column 1, snap fit switch 3 comprises the engagement section that cooperates with draw-in groove 6 and the operating portion that is used for operation.Below the circle platform 5 of top middle circle platform 4 is arranged, middle circle platform 4 is fixed on the column 1, circumferentially has been arranged symmetrically with three groups of pre-tightening apparatus assemblies at middle circle platform 4.Every group of pre-tightening apparatus assembly comprises handle 14, connecting rod 13, pull back spring 15, handle 14 is hinged with middle circle platform 4, links to each other with pull back spring 15 again, and is hinged with connecting rod 13 again, pull back spring 15 other ends link to each other with middle circle platform 4, and connecting rod 13 other ends and shell 7 are hinged.Bottom circle platform 2 is arranged below middle circle platform 4, and bottom circle platform 2 is fixed on the column 1.Three groups of fixing device components circumferentially have been arranged symmetrically with along bottom circle platform 2.Every group of fixing device component comprises support 11 and rubber pad 12, and support 11 1 ends and bottom circle platform 2 are hinged, and the other end and rubber pad 12 are hinged.

When needing broken window, first anchor fitting is scattered, press the handle 14 that is arranged symmetrically with along middle circle platform 4, utilize lever principle, only need less power with connecting rod 13 along column 1 to pressing down, to move downward with spring 10 thereby drive shell 7, treat that the draw-in groove 6 on the shell 7 moves along snap fit switch 3, engagement section distortion and the return of snap fit switch 3 catch on draw-in groove 6, can loose one's grip.Pull down safety cap 9, expose striker 8.At this moment, three rubber pads 12 by being pressed on the forms, are extruded inner air, owing to support 11 can rotate around bottom circle platform 2, thereby can not be subjected to the restriction of forms shape, and can fix whole device.Under the scantling of structure appropriate design, after fixing, then distance presses the operating portion of snap fit switch 3 a suitable scope between striker 8 and the forms, when separating with draw-in groove 6, under the rebound effect of spring 10, drives shell 7 and striker 8 rapid directive forms.Striker 8 tops are sharp, and under powerful impact, forms can be broken, thereby reach the purpose of escape.

Behind the broken window, put safety cap 9, extract rubber pad 12, the utility model is kept well, in order to use next time.
