Bounce formula escape glass breaker
Technical field
The invention belongs to the safe escape technical field, relate to the safe escape device in the space that glass component is installed.
Background technology
In the space that modern vehicle and some building spaces or other supply people to shelter oneself glass, case hardened glass are installed mostly; When emergency situation takes place,, want free-hand it is broken hardly maybe no matter wherein whether contain the PVB tough film; And safety hammer now commonly used exist be prone to lose, operational hazards, shortcoming that reliability is not high; Especially when situation was abnormally dangerous, it was bigger to want to break the glass difficulty into pieces with hammer by easy stages, and passengers also lack the guidance of correct method of application.
Design and a kind ofly can avoid above shortcoming, be fixed in escape glass breaker on glass and easy to use and become demand objectively.
Summary of the invention
The object of the present invention is to provide a kind of formula escape glass breaker that bounces, can easily break glass with manpower, and convenient and reliable, stability and safety.
For reaching above purpose, the solution that the present invention adopted is:
A kind of escape glass breaker comprises fixed cover, bounces body, and this fixed cover comprises that at least one holds the passage that this bounces body, and this passage is a free-running fit with bouncing body; This bounces body has an impact end and and bounces end.
Further, also comprise a safety plug, this safety plug passes and holds on the passage that bounces body and bounce the through hole that is provided with on the body, this is bounced body fix.
This impact end is provided with the thimble that impacts glass.
The travel range of this thimble is that 5mm is to 20mm.
This thimble employing hardness is higher than the material of HRC60, like 45 case-hardening steels.
This passage adopts H7/g6 or H7/f6 with the free-running fit of bouncing body.
The main body of bouncing body adopts the cylinder of diameter 50mm, bounces end and adopts diameter 60mm ball-crown body; The pitch of enters of the impact glass that is provided with on the impact end is 10mm, and coning angle is the 50-70 degree, preferred 60 degree.
This fixed cover has base, and fixed cover base thickness is 2mm, and shape is that the length of side is the square of 100mm.
Owing to adopted such scheme, the present invention to have following characteristics: 1. simple, operation does not easily have dangerous; 2. just existing window is transformed, can't be done very big change,, can popularize rapidly so should use practical basis to the automobile miscellaneous part.Safety plug on the similar fire extinguisher of safety plug used in the present invention more has application foundation; 3. be pure physical structure basically, security of system is stable, can change to bounce through telescopic adjustment to receive force-stroke, and it is wide to be suitable for the crowd; 4. easy to installation and maintenance, be fixed on car wall or the wall, be difficult for losing; 5. cost is compared with original window does not increase what, and the cycle of designing and developing and manufacturing is short.
Description of drawings
Fig. 1 is the generalized section of embodiment of the invention structure.
Fig. 2 is the side cut away view that the present invention is installed on embodiment on glass.
Fig. 3 is a front schematic view embodiment illustrated in fig. 2.
The specific embodiment
Below in conjunction with the accompanying drawing illustrated embodiment the present invention is further described.
See also Fig. 1-3, a kind of formula escape glass breaker that bounces of the present invention comprises fixed cover 1, bounces body 2, and this fixed cover 1 comprises that also one holds this passage that bounces body 23, and this passage 3 is a free-running fit with bouncing body 2; For example adopt H7/g6 or H7/f6.
This bounces body 2 has an impact end 21 and and bounces end 22, and this impact end 21 is provided with the thimble 23 that impacts glass.
Also comprise a safety plug 4, this safety plug 4 passes and holds on the passage that bounces body 2 and bounce the through hole that is provided with on the body, this is bounced body 2 fix.
The main body of bouncing body 2 adopts the cylinder of diameter 50mm, bounces end 22 and adopts diameter 60mm ball-crown body; The thimble 23 of the impact glass that is provided with on the impact end 21 highly is 10mm, and the cone angle alpha of axle section is 60 degree.
The initial stroke of thimble is about 5mm, but when bouncing, can pass through telescopic adjustment, and whole travel range is that 5mm is to 20mm.
Bouncing the body diameter is 50mm, and an end end impacts head, diameter 60mm, and thimble is arranged at other end top, and coning angle is 60 degree, and feasible region is the 50-70 degree, and thimble adopts hardness such as 45 case-hardening steels to be higher than the material of HRC60.Other part of device can adopt common plastics to process.
Install when of the present invention, can with the base of fixed cover 1 one ends through three screw retention on car wall or wall 1.Fixed cover base thickness is 2mm, and shape is that the length of side is the square of 100mm.Whole device can be installed in the upper left corner or the place, the upper right corner of window.
When emergency situation takes place when, pull out safety plug 4, the stroke of body 2 is bounced in flexible adjustment (or not adjusting); Firmly impact with hand subsequently and bounce end 22, thimble 23 just will be answered back to rapidly on (tempering) glass 5, under impact pressure effect greatly; 5 fragmentations of (tempering) glass help people's escape.
The above-mentioned description to embodiment is can understand and use the present invention for ease of the those of ordinary skill of this technical field.The personnel of skilled obviously can easily make various modifications to these embodiment, and needn't pass through performing creative labour being applied in the General Principle of this explanation among other embodiment.Therefore, the invention is not restricted to the embodiment here, those skilled in the art should be within protection scope of the present invention for improvement and modification that the present invention makes according to announcement of the present invention.
