Description
Technical field
The utility model relates to a kind of civil air defense constructions and installations device, is specifically related to a kind of Electric Explosion-proof door.
Background technology
The access of civil air defense constructions and installations is generally the weakest position of whole Civil Air Defense Facilities, generally arranges explosion proof door at the access place of civil air defense constructions and installations, and the shock wave produced that explodes to defend wartime destroys.Explosion proof door generally comprises doorframe, door leaf, hinge (having another name called hinge) and locking.For improving the keying efficiency of explosion proof door, existing explosion proof door adopts motor to drive locking mostly, if but motor shortage safeguards easy damage, and easily malfunctioning after suffering shock wave, reliability is lower.If particularly shock wave causes explosion proof door doorframe or door leaf distortion, then locking needs to apply larger strength and just can reopen, and the constant motor of existing power output cannot provide larger power to open locking.
Utility model content
In view of this, the utility model discloses the high Electric Explosion-proof door of a kind of operation stability.
The purpose of this utility model is achieved through the following technical solutions: a kind of Electric Explosion-proof door, comprise doorframe, door leaf and the hinge both connection, also comprise locking, described locking comprises one and is fixed on the first drive plate in door leaf, first drive plate is provided with two with the centrosymmetric fixed leg of the first drive plate, two fixed legs is respectively equipped with a level and mutually reverse transmission arm; The end of transmission arm is provided with latch segment, is provided with the locking slot corresponding with latch segment inside doorframe; Described locking also comprises the drive motors that driving first drive plate rotates; Described locking also comprises the first hand wheel arranged on door leaf, is provided with the second drive plate bottom the first hand wheel, and the first drive plate and the second drive plate are connected by a driving belt.
Drive motors can drive the first drive plate to rotate, thus drives transmission arm to move horizontally, and finally realizes the closed of latch segment and locking slot and is separated.Described drive motors can select the motor of any one prior art to realize.The utility model arranges the first hand wheel especially, when motor is malfunctioning or be short of power locking cannot be driven to open and close time, by manual rotation first hand wheel, just can drive first drive plate rotate, guarantee the reliability that explosion proof door opens and closes.In addition, be connected by belt between second drive plate with the first drive plate, relative to the drive mechanism of other rigidity such as gear, belt has stronger toughness and ductility, effectively can avoid being out of shape because of impact, damaging, make the utility model explosion proof door have higher reliability.In drive plate the utility model, the structure that motor, doorframe, door leaf, hinge etc. are not described in detail, all can adopt any one existing techniques in realizing.
Further, described transmission arm is provided with the stress fracture groove of multiple tracks longitudinal direction; The bottom of described transmission arm is provided with sawtooth, and the below of transmission arm is provided with the travelling gear of multiple and described engagement, and the center of travelling gear is connected with the second hand wheel.
As the first drive plate damages, also by the second hand wheel, locking is controlled.For avoiding the work affecting locking because of transmission arm distortion, the utility model arranges longitudinal stress fracture groove especially on transmission arm, and when transmission arm local distortion is excessive, the stress because of transmission arm ruptures by the stress fracture groove of this position vicinity.Now still can continue through the second hand wheel, drive that a part of linking arm be connected with latch segment to control locking, improve the reliability of the utility model explosion proof door further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of the utility model travelling gear.
Detailed description of the invention
The utility model to be described in further detail below in conjunction with accompanying drawing and embodiment for the ease of it will be appreciated by those skilled in the art that:
Embodiment 1
The present embodiment provides a kind of Electric Explosion-proof door, comprise doorframe 1, door leaf 2 and the hinge 3 both connection, also comprise locking, described locking comprises one and is fixed on the first drive plate 4 in door leaf, first drive plate is provided with two so that the centrosymmetric fixed leg of the first drive plate 41, two fixed legs to be respectively equipped with a level and mutually reverse transmission arm 5; The end of transmission arm is provided with telescopic latch segment 51, is provided with the locking slot 11 corresponding with latch segment inside doorframe; Described locking also comprises the drive motors (not show) driving drive plate to rotate; Described locking also comprises and is provided with the second drive plate 7, first drive plate 4 bottom the first hand wheel 6, first hand wheel of arranging on door leaf and the second drive plate 7 is connected by a driving belt 71.
Further, described transmission arm 5 is provided with the stress fracture groove 52 of multiple tracks longitudinal direction; The bottom of described transmission arm is provided with sawtooth 53, the below of transmission arm be provided with 6 with the travelling gear 81 of described engagement, the center of travelling gear is connected with the second hand wheel 82.
In the utility model, motor and mounting means thereof can select any one existing techniques in realizing.Existing brushless electric machine such as can be selected to be connected with the first drive plate by existing reducing gear.
Be more than wherein specific implementation of the present utility model, it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these apparent replacement forms all belong to protection domain of the present utility model.Unspecified part, all can select any one existing techniques in realizing.
