Description

Press type spring window breaking device

Technical Field

The utility model relates to a car safety auxiliary device especially relates to a broken window ware of push type spring.

Background

The safety hammer commonly used is the metal hammer of tip usually, hits garrulous toughened glass through waving the safety hammer, and this type of safety hammer often need beat the toughened glass edge vigorously and just can effectively hit garrulous toughened glass, and the toughened glass who hits commonly used on the car is very difficult to hit fast to the strength such as old man child, especially in the environment under water, the resistance of water has restricted the speed that the people swung the safety hammer greatly for people are more difficult to hit garrulous window glass.

SUMMERY OF THE UTILITY MODEL

In order to overcome the not enough of above-mentioned prior art, the utility model provides a broken window ware of push type spring, this broken window ware not only old man child etc. can both easily use it to break door window glass under emergency, also have fine broken window effect under water moreover.

The utility model adopts the technical proposal that:

a press type spring window breaker comprises a button, a main spring, a hammer, a return spring and a hammer tip which are sequentially arranged in a shell from top to bottom; button and drive hammer on be equipped with the direction inclined plane that the direction is the same, the button only can be followed shell longitudinal motion, is equipped with on the drive hammer and runs through the radial card needle of drive hammer, card needle both ends inlay in establishing the draw-in groove at the shell inner wall, the button downstream can rely on the inclined plane of direction to make the drive hammer rotatory to make card needle slide along the draw-in groove, reset spring upper end offsets with the drive hammer, the lower extreme is connected with the shell, the shell lower extreme is located to the hammer point, the hammer point both ends all are equipped with spacing boss, main spring's stiffness coefficient be greater than reset spring.

In the technical scheme, the clamping groove comprises three sections of a vertical groove, a transverse groove and a chute, one end of the transverse groove is connected with the lower end of the vertical groove, and the other end of the transverse groove is connected with the upper end of the chute.

The guiding bevel on the button and the guiding bevel on the hammer are not completely projected in the longitudinal direction and are offset by an angle.

The stiffness coefficient of the main spring is preferably 3-6 times of that of the return spring.

The hammer is preferably made of high-speed steel.

The hammer tip is preferably made of tungsten steel and other hard alloys.

Preferably, a vertical guide groove is formed in the housing, and the button is inserted into the guide groove and can only vertically move along the guide groove.

In this push type spring breaks window ware, the coefficient of stiffness of main spring is reset spring's several times, support this broken window ware hammer point on window glass, press the button, because the hammer is blocked on the shell by the card needle, the main spring is compressed, when the button pushes down when exceeding the certain distance, direction inclined plane on the button makes the hammer take place rotatoryly with the direction inclined plane interact on the hammer, the card needle follows rotatory and can slide along the draw-in groove of shell, at this moment, the hammer can axial displacement, thereby compress reset spring and hit the hammer striking to the hammer point simultaneously under the effect of the main spring that compresses tightly, realize broken window, loosen the button, the button returns the normal position under reset spring's effect with the hammer, the draw-in groove on the shell is drawn back again to the card needle, accomplish a broken window process.

Compared with the prior art, the beneficial effects of the utility model are that:

the window breaking device does not need to be swung forcefully by a large margin, the purpose of breaking the window glass can be achieved only by abutting the hammer tip of the window breaking device on the glass and pressing the button, so that a good window breaking effect is achieved underwater, people with small strength can use the window breaking device easily, and the window breaking device also has a good effect on the window glass pasted with the explosion-proof film.

Detailed Description

The structure and the working principle of the pressing type spring window breaking device of the present invention are explained below with a specific example, but the present invention is not limited to the pressing type spring window breaking device of the present invention.

In the shell 3 in fig. 1, a hammer tip 1, a reset spring 2, a hammer 5 and a main spring 7 are sequentially arranged from bottom to top, a button 6 is slightly longer than the maximum diameter of the hammer and penetrates through the hammer, the bottom of the button 6 and the top of the hammer 5 are provided with guide inclined planes in the same direction, the reset spring has clockwise pretightening force, a guide groove is formed between the shell 3 and the button 6, the shell 3 and the button 6 cannot relatively rotate, and clamping grooves are symmetrically carved on the shell 3 by taking a shell shaft as a center.

In the embodiment shown in fig. 2, the latch 4 and the hammer 5 are combined as shown in the figure, and both ends protrude by 1 mm.

The guiding bevel on the button and the guiding bevel on the hammer are not completely projected in the longitudinal direction and are offset by an angle. Thus, after the two guide slopes are contacted, the hammer can be driven to rotate by the button moving downwards.

The draw-in groove is including erecting groove, horizontal groove and chute three-section, and horizontal groove one end links to each other with erecting the groove lower extreme, and the horizontal groove other end links to each other with the chute upper end.

In fig. 3, the moving track of the card pin 4 in the card slot of the housing, when not pressed, the card pin is at the top of the card slot 4, in the process of pressing force application, the card pin 4 is held by the horizontal part (i.e. the transverse slot) of the card slot, and then pressure is continuously applied, the hammer 5 is rotated by the button 6 in the counterclockwise direction, the card pin 4 is separated from the transverse slot of the card slot and slides to the inclined slot section, the compressed main spring 7 works to push the hammer, the hammer compresses the return spring and hammers the hammer tip, thereby breaking the window, and after the hand is loosened, the return spring 2 pushes the hammer 5 and the card pin 4 to reset.

In the above examples, the hammer material may be high-speed steel to improve the impact force when striking the hammer head. The stiffness coefficient of the main spring is 600N/m, and the extreme coefficient of the return spring is 100N/m.
