Description

Press arm vehicle glass destroyer

Technical field

This utility model relates to fire-fighting equipment field, particularly relates to a kind of Press arm vehicle glass destroyer.

Background technology

In automobile breaking out of fire or when falling into the water, the occupant in automobile needs broken vehicle glass fast-escape, but vehicle glass mostly is safety glass, it is difficult to free-hand broken, needs to crush by glass breaker.

But conventional glass breaking hammer mostly is tip iron hammer, and hangs in automobile bodies by tip iron hammer, easily occurs stealing and lose, or drop because of collision when traffic accident occurs, lose, cause quartering hammer be difficult to found and use.

Utility model content

This utility model is intended to provide a kind of Press arm vehicle glass destroyer, in order to crushes vehicle glass and is difficult to lose.

Press arm vehicle glass destroyer in this programme, including bearing, rotating shaft it is hinged with on bearing, being fixed with handle on the side of rotating shaft one end, the axis of handle is perpendicular to shaft axis, and the side of the other end relative with handle in rotating shaft is fixed with pressure arm, the axis of pressure arm is perpendicular to shaft axis, the free end of pressure arm is perpendicular on the axis direction of pressure arm be fixed with conical indenter, and the axis of conical indenter is perpendicular to the axis of rotating shaft, and rest base is covered with adhesion layer.

The know-why of this programme and have the beneficial effect that Press arm vehicle glass destroyer is sticked on vehicle glass by the adhesion layer of rest base, promote handle, make axis of rotation, rotating shaft drives pressure arm to rotate, pressure head on pressure arm is offseted with glass, owing to the big multipotency in safety glass surface bears the pressure of tens of MPa, pressure head is set to taper, makes pressure head control at 0.5mm with the contact area of glass surface²Below, the direction promoting handle to rotate applies ever-increasing pressure, and then the conical indenter on drive pressure arm applies pressure to glass and produces pressure, when the maximum pressure that pressure can bear more than glass, glass breaking with pressure head contact position, owing to glass enbrittles, make monolithic glass fragmentation after the some fragmentation on glass, thus monoblock vehicle glass crushes.Rest base adhesion layer is easy to be fixed on glass Press arm vehicle glass destroyer, and adhesion layer adheres to the most firm, and Press arm vehicle glass destroyer is less susceptible to lose.

Next adult of ordinary circumstance can apply the power of more than 1000N, can make pressure head that glass is produced more than 200MPa pressure, and therefore this programme can easily crush tempered glass of automobile.

Prioritization scheme one based on such scheme: the length of described handle is more than the length of pressure arm, when the stress point of handle and pressure arm is all at the end of handle and pressure arm, according to lever principle, the pressure that pressure arm produces is more than thrust suffered on handle, thus play the effect amplifying thrust, and then more laborsaving.

Prioritization scheme two based on scheme one: the angle of described handle and pressure arm is 90 °, when the pressure head on pressure arm offsets with glass, handle turns to be perpendicular to glass direction, now applies the space maximum of thrust, convenient applying thrust to handle.

Prioritization scheme three based on scheme two: described handle length is less than 20cm, it is to avoid handle length is long and too much takies interior space and is not easy to apply thrust to handle.

Prioritization scheme four based on scheme three: described handle and described pressure arm are the metallic rod that diameter is more than 10mm, it is ensured that handle and pressure arm have some strength, it is to avoid handle and pressure arm fracture during broken glass, thus avoid glass breaker to lose efficacy.

Accompanying drawing explanation

Fig. 1 is the structural representation of this utility model embodiment Press arm vehicle glass destroyer.

Detailed description of the invention

Below by detailed description of the invention, this utility model is described in further detail:

Reference in Figure of description includes: bearing 1, rotating shaft 2, handle 3, pressure arm 4, conical indenter 5, adhesion layer 6, glass 7.

Embodiment Press arm vehicle glass destroyer is the most as shown in Figure 1: include bearing 1, rotating shaft 2 it is hinged with on bearing 1, it is fixed with handle 3 on the side of rotating shaft 2 one end, the a length of 8cm of handle 3, the axis of handle 3 is perpendicular to rotating shaft 2 axis, pressure arm 4 it is fixed with on the side of the other end relative with handle 3 in rotating shaft 2, the a length of 16cm of pressure arm 4, the axis of pressure arm 4 is perpendicular to rotating shaft 2 axis, the angle of handle 3 and pressure arm 4 is 90 °, handle 3 and pressure arm 4 are the aluminium alloy rod of a diameter of 12mm, the free end of pressure arm 4 is perpendicular on the axis direction of pressure arm 4 be fixed with conical indenter 5, the axis of conical indenter 5 is perpendicular to the axis of rotating shaft 2, adhesion layer 6 it is covered with bottom bearing 1.

Sticking on vehicle glass 7 by vehicle glass 7 destroyer by the adhesion layer 6 bottom bearing 1, promote handle 3, make rotating shaft 2 rotate, rotating shaft 2 drives pressure arm 4 to rotate, and is offseted with glass 7 by the pressure head 5 on pressure arm 4, and pressure head 5 is 0.4mm with the contact area on glass 7 surface²The direction promoting handle 3 to rotate applies ever-increasing pressure, conical indenter 5 on pressure arm 4 applies ever-increasing pressure to glass 7, when pressure reaches more than 200N, pressure head 5 produces more than 100MPa pressure to glass 7, the pressure that can bear more than safety glass 7, crush with the glass 7 of pressure head 5 contact position, owing to glass 7 enbrittles, make monolithic glass 7 fragmentation after the some fragmentation on glass 7, thus monoblock vehicle glass 7 crushes.

Above-described is only embodiment of the present utility model, and in scheme, the known general knowledge such as concrete structure and characteristic too much describes at this.Should be understood that; for a person skilled in the art, on the premise of without departing from this utility model structure, it is also possible to make some deformation and improvement; these also should be considered as protection domain of the present utility model, and these are all without affecting effect and the practical applicability that this utility model is implemented.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. records the content that may be used for explaining claim.
