Abstract

The utility model relates to a broken window ware, mainly for a broken window sword that has the long arm, broken window sword include the pin joint on the window frame the cutter body and by the motion arm of the afterbody epitaxy play of cutter body, the cutter body uses the pin joint axle to extend to window glass orientation as the benchmark, the operation end of motion arm is retrained near the window frame by extension spring, this broken window ware theftproof function is strong, can relax, break fast the window when emergency appearing.

Description

Window breaker

Technical field

The utility model relates to a kind of window breaker, belongs to security against fire resist technology field.

Background technology

Along with the progress of industry and the development in city, the quantity of automobile also grows with each passing day, but the safety problem of automobile also happens occasionally.Once presence of fire, often because break window not in time, and cause casualties, though have safety hammer in current automobile, existing safety hammer has following shortcoming: structural limitations, is easy to be taken away by people, does not have anti-theft feature; Compact structure is convenient, but its knock strength also can be very little, need glass for vehicle window to be smashed with the long period, this has just delayed best escape time; Electronic warning safety hammer structure is complicated, manufacturing cost is higher.

Utility model content

Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides a kind of anti-theft feature strong, when being in an emergency can easily, the window breaker of broken window fast.

In order to solve above technical matters, the utility model provides a kind of window breaker, be mainly one and have long-armed broken window cutter, broken window cutter comprises and is articulated in cutter hub on window frame and by the motion arm extended outside the afterbody of cutter hub, the point of a knife of cutter hub is that benchmark extends to wind glass direction with drive-connecting shaft; The operating side of motion arm constrains near window frame by extension spring; .

The technical scheme that the utility model limits further is:

Further, also comprise remote control handle, remote control handle is fixedly connected with the operating side of motion arm by steel rope, and this can realize driver directly can abolish tailstock glass at operator's compartment.

Further, be also provided with surface of a wound expansion instrument in the end of cutter hub, surface of a wound expansion instrument is with the knife face of cutter head for benchmark extends to its outside, and this is the expansion in order to realize damaged mouth, and the cut preventing sharp-pointed cutter head from being formed is less.

Further, surface of a wound expansion instrument forms primarily of screw bolt and nut, has carry out for bolt, nut the through hole that assembles in the end of cutter hub.

Further, remote control handle comprises a support and is erected at the lever that support also can carry out closing around it nodular rotation, and the operating side of lever is provided with handle, one end of the coupling end connecting steel wire ropes of lever.

Further, the rope body of steel rope, through some swivel bearings, is provided with protective cover at swivel bearing and rope body contact side, and protective cover both can carry out one constraint to steel rope, also can prevent foreign material from falling in bearing simultaneously and cause obstruction to the movement of steel rope.

Further, the point of a knife of broken window cutter can design mix forked, the point of a knife of forked can stretch to the glass of the window frame left and right sides respectively, and such a set of equipment can realize the function simultaneously abolishing two sides window, greatly can shorten passenger like this and escape the required time.

The beneficial effects of the utility model are: window breaker is directly installed on window frame, have stopped stolen possibility; Utilize lever principle, only need to apply less rotational force, larger impulsive force can be produced to glass, make brokenly window become very light, convenient; Add remote operation handle, facilitate driver directly to carry out brokenly window action; The cutter head of broken window cutter can design mix forked, the cutter head of forked can stretch to the glass of the window frame left and right sides respectively.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

embodiment 1

The window breaker that the present embodiment provides, as shown in Figure 1, the broken window cutter 1 of F type is articulated on window frame 2 by bearing pin 13, the point of a knife of broken window cutter 1 with the S. A. of himself for benchmark extends to wind glass 3 direction, the motion arm 4 of broken window cutter 1 constrains near window frame 2 by extension spring 5, remote control handle comprises a support 6 and sets up the lever 7 that also can carry out closing around it nodular rotation on the frame 6, the operating side of lever 7 is provided with handle 8, one end of the coupling end connecting steel wire ropes 9 of lever 7, the rope body of steel rope 9 is connected with the operating side of motion arm 4 through some swivel bearings 10, protective cover 11 is provided with at swivel bearing 10 and rope body contact side, surface of a wound expansion instrument is bolt 12, and bolt 12 is fixed in the through hole of cutter hub end by nut.

During manual operation, only need hold motion arm 4 outwards (in compartment direction) wrench, F shape cutter head can directly form an impulsive force to glass thus crush glass for vehicle window, and then passenger kicks glass suddenly, can break window; During remote control, driver holds handle 8 and upwards wrenches, and can drive F shape cutter head same with the steel rope 9 that remote control handle is connected forms an impulsive force to glass thus crush glass for vehicle window, and then passenger kicks glass suddenly, can break window.

In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
