Abstract

The invention relates to a window breaker, and belongs to the technical field of escape tools. The window breaker comprises a straight pipe with a closed end, an inner pipe sleeved in the straight pipe, and a spring and a firing pin which are arranged in the inner pipe; and a latch is hinged on the side wall of the inner pipe, one end of the latch is matched with the shaft shoulder of the firing pin, and the other end of the latch is matched with the inclined plane of the inner wall of the straight pipe. The window breaker has the advantages of high window breaking efficiency, convenience in use and carrying and the like.

Description

Window breaker

Technical field

The present invention relates to a kind of window breaker, belong to the escaping tool technical field.

Background technology

At present, the best approach of saving oneself of land craft passenger when accident occurring is broken the window escape, equal supporting window breaker when safety hammer is arranged as emergency escape on the passenger vehicle, existing safety hammer has the small-sized hand hammer of handle and crushing head usually, brandishing behind user's gripping handle that safety hammer needs repeatedly to knock glass could be with glass breaking, the energy that knocks is less, runs into the very easily broken window failure of the less passenger of strength.Can increase brokenly window efficient by weight and the handle that strengthens safety hammer, but public transport means consider the safety when moving and can't adopt, the passenger is that this type of safety hammer of Portable belt is self-defence also can't be by safety check.And car is not equipped with the window breakers such as safety hammer usually, and because the interior space of car is little, and the window breaker of large volume such as safety hammer are difficult to be placed on position within reach, even if use the broken window of safety hammer, the scope of arm motion also limited the energy that knocks glass, broken window efficient is extremely low.

Summary of the invention

The technical problem to be solved in the present invention is to propose little, the broken high window breaker of window efficient of a kind of volume.

The present invention is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of window breaker, the straight tube that comprises end sealing, be placed in the inner tube in the straight tube, and be located at spring and striker in the inner tube, be hinged with tenon on the sidewall of inner tube, one end of tenon cooperates with the shaft shoulder of striker, and the other end of tenon cooperates with the inclined-plane of straight tube inwall.

Preferably, straight tube is externally connected with link plate, has hanging hole on the link plate.

Preferably, have groove on the link plate, an end of groove has opening, and the other end is provided with blade.

Preferably, the closed end of straight tube is outward extended with whistle.

Window breaker of the present invention is compared the broken window instruments such as existing safety hammer owing to having adopted spring to add the structure of striker, and the beneficial effect that has is:

1, volume is small and exquisite, is easy to carry, and especially can directly hang on the key after setting up hanging hole.

2, rely on the elastic force of spring to give the strength that striker breaks window, broken window efficient is high, simple to operation, is not subjected to the restriction of operator's muscle power.

The function that 3, can realize cutting safety strap and emergency by the blade set up and whistle, one-object-many-purposes.

Description of drawings

The invention will be further described below in conjunction with accompanying drawing.

Fig. 1 is the structural representation of the embodiment of the invention one.

Fig. 2 is the use constitution diagram of Fig. 1.

Fig. 3 is the structural representation of the embodiment of the invention two.

The specific embodiment

Embodiment one

The window breaker of the present embodiment as shown in Figure 1, the straight tube 1 that comprises end sealing, be placed in the inner tube 2 in the straight tube 1, and be located at spring 4 and striker 3 in the inner tube 2, be hinged with tenon 5 on the sidewall of inner tube 2, one end of tenon 5 cooperates with the shaft shoulder of striker 3, and the other end of tenon 5 cooperates with the inclined-plane 6 of straight tube 1 inwall.

During use, as shown in Figure 2, with inner tube 2 openings of the window breaker of the present embodiment towards glass for vehicle window, with the afterbody extruding of hand at window breaker, so that straight tube 1 moves to inner tube 2, the inclined-plane 6 of straight tube 1 inwall promotes an end of tenons 5, it is rotated around hinge, the other end of tenon 5 is away from the shaft shoulder of striker 3, and striker 3 to the glass for vehicle window motion, smashes glass for vehicle window under the promotion of spring 4.

Embodiment two

The window breaker of the present embodiment is the improvement on embodiment one basis, and as shown in Figure 3, its improvements are: straight tube 1 is externally connected with link plate 7, have hanging hole 8 on the link plate 7, also have groove 9 on the link plate 7, an end of groove 9 has opening, and the other end is provided with blade 10.

Above-mentioned improvement, can be used to be difficult for losing as hanging hole 8 is hung on the car key on the one hand so that the window breaker of the present embodiment is easy to carry at any time.Can fast and effeciently cut off safety strap with its all-in-one-piece groove 9 with blade 10 on the other hand, realize fast-escape.

Embodiment three

The window breaker of the present embodiment is the improvement on embodiment two bases, and as shown in Figure 4, its improvements are: the closed end of straight tube 1 is outward extended with whistle 11, can be used for sending calling help signal after escape.

The above only is preferred embodiment of the present invention, as long as adopt technical scheme of the present invention, perhaps modification or the equivalent variations made based on conventional means on it of those skilled in the art all drops in the protection domain of requirement of the present invention.

Claims
