Description
Technical field
The present invention relates to window breaker technical fields, and in particular to a kind of stationary type multidirectional window breaking device.
Background technique
Bus, car tourist communications common tool.Present bus and bus automobile, in order to more
It runs quickly on expressway fastly, mostly uses the toughened glazing panes of monolith.Vehicle is during long-distance running, inevitably
Some contingencies occur.This kind of vehicle is occurring to burn in railway carriage or in the case where automobile overturning, the passenger in railway carriage is often
It needs to implement within first time to save oneself, breaks glass for vehicle window, get through outside escape route.In order to be easy in emergency event
It escapes, is provided with window breaker on present car, can be used to smash glass pane realization escape when encountering emergency situation.Going out
When now unexpected, passenger first has to find window breaker, also to have correct broken window method that could break automobile window, in anxiety
In the case where flurried, passenger will not only take rapidly window breaker, and also wanting can be proper use of, this often has a certain difficulty, and one
Window breaker falls off in denier percussion, and consequence is hardly imaginable, can not only delay valuable time in this way, and passenger possibly even loses escape
Chance.There is the insufficient defect of operation ease in the window breaker of existing car.For the deficiency for solving existing window breaker, Zhong Duozhuan
Benefit provides miscellaneous window breaker scheme.If Authorization Notice No. is a kind of CN105999572A " multifunctional steam vehicle window breaking
Device ", CN206566367U " a kind of window breaking device and use the window breaking device " etc., these window breakers are all that bus is anticipated
Emergency escape is to provide beneficial tool, but they have a common defect when outer, carrys out temporary needs in danger and finds
Window breaking tool, and because the window breaker provided is more small and exquisite, the hardness for launching spring is very strong, and the old and the weak and child are difficult to normal use,
Even adult, if strength is not enough or application method does not realize that escape is saved oneself to being all difficult to break into pieces tempered glass；Especially vehicle
When 90 degree of tippings, passenger is difficult to get window breaker, even if getting window breaker, can not also use window breaker at all
The tempered glass for being placed in top is tapped.And the patent of CN206644777U " slidingtype public transport vehicle window breaking device ", although
Compared with common window breaker, maximum difference is that vehicle window two sides are respectively arranged row's sliding rail, makes to consolidate originally
Being scheduled on one jiao of vehicle window of window breaker can slide in sliding rail, increase to make window breaker that can break window position, when generation fire
When, driver can control window breaker and strike vehicle window respectively in the different parts of vehicle window, accelerates vehicle window broken and disintegrates.The patent without
Need manpower to break window, easy to control, high degree of automation, but structure is complicated, it is with high costs, and if the first time of traffic accident will
Automatic control system is destroyed, then all passengers will be unable to self-help escape.
" a kind of fast window breaker and its application method for being fixed on car glass window edge " (CN2018108010692's)
Patented technology is fixed on the method on vehicle window using by window breaker, can not find the danger of window breaker when capable of preventing from needing
Danger, also can Reusability achieve the purpose that brokenly window；Also the glass on top can be crushed when vehicle rollover；But
Movement is not quick when the device uses, and broken window effect can have a greatly reduced quality, and the above design works as vehicle since positioning head is not able to rotate
When overturning makes the handle of window breaker be not in lower section, user has can not normal use window breaker.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of stationary type multidirectional window breaking devices, can be fine
Ground overcomes drawbacks described above.
The technical solution adopted by the invention is as follows: a kind of stationary type multidirectional window breaking device, including it is positioning head, rotary head, short
Bar, stock, clamp, ejector；It is characterized in that, being provided with newel and internal screw thread on the positioning head；Newel, which passes through, to be turned
Hole and cover board are fixed together, in rotation connection between positioning head and rotary head；Major part screw passes through on washer and tempered glass
Preformed hole screws in the internal screw thread of positioning head, and tempered glass and positioning head are fixed together；Quarter butt is provided on the quarter butt
Plug, first rotating shaft, the second shaft and ejector；First rotating shaft is hinged by quarter butt plug and rotary head；Second shaft will
Quarter butt is hinged with stock；Handle, handle gum cover and the first high magnetic steel are provided on the stock；The both ends of the clamp
It is provided with clamp baffle, centre is provided with raised line；It is opened up at the interior angle at both ends fluted；Second high magnetic steel is fixed in cushion block
Between, cushion block bonds together with clamp, and double-sided adhesive bonds together cushion block and tempered glass；The ejector is towards tempered glass
Be provided on one side steel pricker compression head；First high magnetic steel can be attracted across clamp by the second high magnetic steel；First high magnetic steel

The rotary head can be rotated by the center of circle of positioning head central axis A；When tempered glass is in vertical installation, stock
When there is no external force constraint, can naturally droop.
First high magnetic steel is attractive across clamp the second high magnetic steel within 10mm of adjusting the distance；The last the first magnetic
After steel is attached together across clamp and the second high magnetic steel, the first high magnetic steel is greater than kilogram the pressure that clamp is formed；By first
High magnetic steel is placed between two raised lines, and after being attached together across clamp and the second high magnetic steel, raised line can stop the last the first magnetic
Steel is mobile by the center of circle of positioning head central axis A；Pressure is applied for the center of circle along positioning head central axis A to stock, when the pressure
Greater than after the resistance of magnetic force and raised line, stock can be detached from the constraint of the second high magnetic steel, shift to clamp baffle；When the pressure of application is big
After the ability to bear of clamp baffle, clamp baffle can be deformed and be stretched, and can not stop the movement of stock again.
The quarter butt is towards the direction rotation for leaving tempered glass, and quarter butt is under the constraint of cover board, the shape between tempered glass
At angle be not more than 10 degree；By stock towards the direction rotation for leaving tempered glass, formed between stock and quarter butt extended line
At about 45 degree, the steel tongue being arranged in stock can eject angle, by the angle locking between stock and quarter butt.
By stock towards the pressuring direction of tempered glass, the steel pricker on quarter butt can be forced to compress head retraction, and trigger ejector
Interior steel pricker is shot towards the direction of tempered glass.
Using technical solution of the present invention, have the following beneficial effects:
1) present invention be fixedly mounted on tempered glass, and design have can 360 degree rotation rotary head, can be realized multiple spot when needing
Position rapid window-breaking；
2) present invention is fixed the lower end of stock using high magnetic steel, and whole device will not be with when can either guarantee normally to drive a vehicle
Any whipping of vehicle, and can guarantee use of in emergency circumstances taking；
3) when vehicle is excessive by external impact force, inertia can make the constraint of stock disengaging high magnetic steel, when accident makes inclination of vehicle
When the present invention can naturally droop, user can conveniently grab take use.
