Description
Technical field
The present invention relates to unblock to set technical field, more particularly to a kind of auto-unlocking device of push type lock.
Background technology
With the continuous improvement of people's awareness of safety, various security protection products arise at the historic moment, and auto-unlocking device is
It is one kind of.Existing lock, have and greatly unlocked using pressure by structure, such as the lock of car belt, pass through pressing
Lock can open safety belt.This pressing type lock, drives also easily usually, once running into emergency, such as intakes,
Pyrotechnics etc. is met, then unlocking just turns into a very difficult thing, therefore a large amount of auto-unlocking devices occurs in market, but existing automatic
Tripper, the defects of complicated, sensitivity is not high and deficiency be present, be still improved space more.
The content of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of compact-sized, setting rationally, spirit
The auto-unlocking device of the high push type lock of sensitivity.
To achieve the above object, the present invention uses following technical scheme：
A kind of auto-unlocking device of push type lock of the present invention, including main cavity and it is connected to main cavity upper end
Depression bar chamber, the depression bar intracavitary is hinged with arc depression bar, and depression bar chamber side wall is provided with outlet, the main body cavity wall pars intermedia
Position is provided with annular card convex, and piston is longitudinally provided with main cavity, compression spring, institute are provided between the piston upper end and annular card convex
State piston and be coated with retainer ring, the retainer ring upper surface is supported and is located at annular snap convex bottom face, the piston upper surface and arc
Shape depression bar lower surface offsets setting.
Further, the piston is fixed with expansion loop, and the retainer ring is coated on expansion loop.
Further, the retainer ring is water-soluble ring, cigarette fusibleness ring or hot melt ring.
Further, piston upper end outer wall is provided with slipping ring.
Further, the main body cavity outer wall upper end is provided with fixed support, and the fixed support is provided with fixing band.
The present invention has the beneficial effect that：Arc depression bar of the present invention, piston, compression spring and retainer ring are equipped with,
After retainer ring chance water, cigarette or heat, rapid fracture, piston is rapidly moving upward in the presence of compression spring, promotes arc
Depression bar rotates, and arc depression bar upper end is stretched out outside outlet, pressing type lock is extruded, effective auto-unlocking.Structure of the present invention
Simply, it is reasonable to set, high sensitivity.

Embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, the auto-unlocking device of a kind of push type lock of the present invention, including the He of main cavity 4
The depression bar chamber 3 of the upper end of main cavity 4 is connected to, above-mentioned two part forms body exterior structure of the present invention.
Arc depression bar 6 is hinged with the depression bar chamber 3, arc depression bar 6 is rotatably disposed within depression bar chamber 3, the side of depression bar chamber 3
Wall is provided with outlet 13, and so that the one end of arc depression bar 6 is stretched out outside outlet 13, push type lock is extruded.
The inwall middle part of main cavity 4 is provided with annular card convex 9, and piston 7, the piston 7 are longitudinally provided with main cavity 4
Compression spring 8 is provided between upper end and annular card convex 9, the lower end of piston 7 is coated with retainer ring 10, the upper end of retainer ring 10
Face is supported and be located at the annular bottom surface of card convex 9, and the upper surface of piston 7 and the lower surface of arc depression bar 6 offset setting.
The retainer ring 10 is water-soluble ring, cigarette fusibleness ring or hot melt ring, that is, meets water, fixed when meeting cigarette or heat
Ring 10 will be broken rapidly.
The preferably lower end of piston 7 of the invention is fixed with expansion loop 5, and the retainer ring 10 is coated on expansion loop 5, swollen
The effect of tensioner ring 5 is exactly to be stuck in when retainer ring 10 is unbroken using it in the groove of piston 7 so as to seized piston 7, prevent its from
It is mobile；After the fracture of retainer ring 10, the lower end of expansion loop 5 can open, and be skidded off from the groove of piston 7, so as to which piston 7 can
Moved up under the impetus of compression spring 8.
The upper end outer wall of piston 7 is provided with slipping ring 12, is mainly used in reducing rubbing between piston 7 and the inwall of main cavity 4
Power is wiped, further improves the sensitivity of the present invention, while plays sealing function, can prevent liquid from surprisingly entering from upper end of the present invention
Entering main cavity 4 causes the present invention surprisingly to be triggered.
The outer wall upper end of main cavity 4 is provided with fixed support 2, and the fixed support 2 is provided with fixing band 1, and fixing band 1 is led
It is used to the present invention being fixed on related push type lock body.
The lower end of piston 7 is connected with notice plate 11, and when piston 7 moves down, notice plate 11 comes off, and indicates progress of the present invention
Work is completed, push type lock has been switched on.
Described above is only the better embodiment of the present invention, therefore all constructions according to described in present patent application scope,
The equivalent change or modification that feature and principle are done, is included in the range of present patent application.
