Abstract
The utility model discloses a pneumatic safety hammer which is mounted on a vehicle body (9) around vehicle window glass (1) and is used for breaking the glass (1) in an emergency. The pneumatic safety hammer comprises a bracket (8), a cylinder (16), a crank-slide block linkage mechanism and a breaking hammer, wherein the bracket (8) is fixed on the vehicle body (9); the crank-slide block linkage mechanism comprises a guide rail (11) fixed on the bracket (8), a slide block (13) sliding on the guide rail (11) and a crank link (4); one end of the crank link (4) is hinged with the slide block (13); the cylinder (16) is fixed on the bracket (8); the front end of a piston rod (15) is connected with the slide block (13) so as to drive the slide block (13) to slide on the guide rail (11); the breaking hammer comprises a hammer handle (6) and a hammer head (7) which are connected with each other; the other end of the crank link (4) is hinged with the hammer handle (6) through a pin (2); and the hammer handle (6) is hinged with the bracket (8) through a pin shaft (3) arranged near the tail end of the hammer handle (6). Toughened glass can be broken through a mechanical manner, and the pneumatic safety hammer is not prone to lose.
Description
Technical field
The utility model relates to the Design of Mechanical Structure technical field, relates in particular to a kind of pneumatic safety hammer that is used in case of emergency breaking glass that is installed on the public transport meanss such as city motor bus.
Background technology
Bus is that a kind of personnel highly assemble, and the space is the osed top transportation means comparatively, and these two characteristics have determined it to have the characteristic of big potential safety hazard inevitably.Because air-conditioned bus all uses the incorporate case hardened glass of window frame, in case of emergency can only smash with safety hammer by hand, and when crowded and situation take place in the compartment of confusion, want easily to smash the thick case hardened glass of 5mm and be not easy.The lawless person's of many evil minds frequent stealing safety hammer is more arranged, and public transport company also is difficult to timely replacement, therefore stays very big potential safety hazard.
The utility model content
The purpose of this utility model provides a kind of mechanical system and smashes case hardened glass, the pneumatic safety hammer that is difficult for losing.
The purpose of this utility model is achieved through the following technical solutions:
A kind of pneumatic safety hammer is installed on the car body 9 of glass for vehicle window 1 periphery, in case of emergency breaks glass 1, comprising: support 8, cylinder 16, crank-sliding block connecting rod mechanism and quartering hammer;
Support 8 is fixed on the car body 9;
The crank-sliding block connecting rod mechanism comprises the guide rail 11 that is fixed on the support 8, the slide block 13 and an end and the slide block 13 pivotally attached crank connecting links 4 that slide on guide rail 11;
Quartering hammer comprises interconnected hammer handle 6 and tup 7, and the other end of crank connecting link 4 is hinged by pin 2 and hammer handle 6;
Described hammer handle 6 is hinged with support 8 by being located near the bearing pin 3 of the end of hammer handle 6.
Described tup 7 front ends are taper.
Described pneumatic safety hammer connects the source of the gas of pneumatic system on the car by starting switch.
The technical scheme that provides by above-mentioned the utility model as can be seen, pneumatic safety hammer described in the utility model can mechanically be smashed case hardened glass, and be difficult for losing.
Description of drawings
Fig. 1 is the front view of the structural representation of pneumatic safety hammer described in the utility model;
Fig. 2 is the left view of the structural representation of pneumatic safety hammer described in the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on embodiment of the present utility model, those of ordinary skills belong to protection domain of the present utility model not making the every other embodiment that is obtained under the creative work prerequisite.
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail.
Embodiment one
As Fig. 1 and shown in Figure 2, a kind of pneumatic safety hammer is installed on the car body 9 of glass for vehicle window 1 periphery, in case of emergency breaks glass 1, comprising: support 8, cylinder 16, crank-sliding block connecting rod mechanism and quartering hammer;
Support 8 is fixed on the car body 9 by screw 10; Support also comprises a riser 5 simultaneously;
The crank-sliding block connecting rod mechanism comprises guide rail 11, is fixed in the slide block 13 and an end and the slide block 13 pivotally attached crank connecting links 4 that slide on the riser 5 of support 8, on guide rail 11;
Quartering hammer comprises interconnected hammer handle 6 and tup 7, and the other end of crank connecting link 4 is hinged by pin 2 and hammer handle 6;
Described hammer handle 6 is hinged with the riser 5 of support 8 by being located near the bearing pin 3 of the end of hammer handle 6.
Described tup 7 front ends are taper.
Described pneumatic safety hammer connects the source of the gas of pneumatic system on the car by starting switch.During use, open starting switch, pressure gas is filled in the suction casig 16 by admission port, store enough pressure, promote piston 17, by piston 17 thrust is passed to piston rod 14, piston rod 14 promotes slide block 13 ahead running in track 11, slide block 13 drivening rod cranks 4 motions then, connecting rod crank 4 motion in a single day, hammer handle 6 will be a center of turn with bearing pin 3, hammer handle 6 drives tups 7 along movement in a curve then, tup 7 will produce very big impulsive force, and the cone by front end smashes glass 1.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
