Gate closing device lockable mechanism
[technical field]
The present invention relates to the gate closing apparatus of intelligent clearance technical field, design a kind of lockable mechanism of gate closing device of traveler self-help transit particularly.
[background technology]
Chinese utility model patent (CN202689782U) discloses a kind of gate closing device with auto-lock function, its concrete technical scheme is: be provided with an electromagnetic lock fixed pole in the framework of gate closing device, this securing rod can eject and insert in the U-shaped groove of clamping block, when revolving door rotates to assigned address, if have external force to push, then revolving door just can self-locking, now, extraneous thrust can not promote revolving door rotation and the thrust in the external world also can not cause any harm to drive motors.The shortcoming of this technical scheme is that electromagnetic locking lever lock stops precision and stressed insufficient strength.
In view of this, the invention provides a kind of lockable mechanism of new gate closing device to solve the problems of the technologies described above.
[summary of the invention]
The object of the invention is to: provide one to have auto-lock function more accurately and firmly gate closing device.
A kind of gate closing device lockable mechanism, this lockable mechanism comprises lock plate and coordinates the fastener playing locking effect with lock plate, described lock plate comprises upper and lower two dishes, upper lock plate is the first lock plate, lower lock plate is the second lock plate, first lock plate diameter is less than the second lock plate diameter, described fastener is divided into upper and lower two parts, upper fastener is the first fastener, lower fastener is the second fastener, first fastener comprises an arc structure, the length of arc is identical with space width on the first lock plate, second fastener is the elastic plate that is flexibly connected with fastener and the fixed structure for fixing the second fastener and elastic plate, described fixed structure is fixed thereon the soffit of portion's braced structures by upper surface, the second described fastener comprises a U-shaped body, one cell body and elastomeric element, U-shaped body is positioned at cell body, described elastomeric element is between U-shaped body afterbody and cell body inwall.
Described tooth body afterbody is provided with a circular port, described elastic plate is provided with tooth body junction the ball bumps coordinated with circular port, this ball bumps coordinates active link activity more flexible with circular port, this cell body and elastic plate can both adapt to the activity in all directions.
The distance of two ports of described U-shaped body is equal with space width on lock plate.
The interposition that described cell body coordinates with U-shaped body is equipped with a projection, and this projection is provided with a dentation tooth body structure
Relative to prior art, gate closing device of the present invention has the following advantages:
1) more stable, the safety of this gate closing device lockable mechanism function;
2) this gate closing device lockable mechanism controlling angle scope is larger.
3) after gear teeth and tooth shape structure are mediated, mechanical locking very tight, not easily slippage.
