Description
Technical field
The utility model belongs to construction elevator door guard technology field, is specifically related to a kind of locking construction elevator door gear.
Background technology
Due to construction safety requirement, construction elevator door (forming primarily of door leaf and doorframe) must by people's (direction of elevator door unlatching is outside) start or stop (close and open) from the outside.Conventional method carries out the start or stop of elevator door at limit pin lock outdoors, and each workman's turnover, uses the start or stop of pin lock also cumbersome.Due to can only from start or stop elevator door outdoors, so as the elevator personnel that take or the negligence of elevator operation personnel is not timely shuts elevator door, and elevator door also cannot be fastened by the workmen in door, opening wide of elevator door, defines great potential safety hazard.If notify that other personnel go out elevator to get on to close the door again, also form the wastings of resources such as manpower, be unfavorable for energy-conservation.
Summary of the invention
For above-mentioned technical matters, the purpose of this utility model is to provide a kind of locking construction elevator door gear, and this device not only can closed outdoors and open construction elevator door, can also close in door and open construction elevator door.
For achieving the above object, technical solution adopted in the utility model is:
A kind of locking construction elevator door gear, it is characterized in that: it comprises snap close, the rearward end of described snap close is provided with hand draw ring; Described snap close bottom is provided with groove, during installation: described groove is stuck on doorframe, hinged inside the rear wall of groove and doorframe; The leading section of described snap close is inclined-plane, when closing door leaf: inclined-plane is pushed in the upper end inside door leaf, and by inclined-plane jack-up; When door leaf cuts out completely, inclined-plane falls after rise, and lower end, inclined-plane fastens the outside of door leaf upper end.
Described snap close rear end is provided with circular hole, is inserted with rotating shaft in circular hole; In described rotating shaft, cover has two collars, and two collars lay respectively at the both sides of snap close, and the described collar is fixedly connected with doorframe by pipe link; Described rotating shaft two ends are equipped with outside thread, and outside thread place is screwed with nut.
The angle of described inclined-plane and horizontal surface is between 15 ° to 45 °.
The angle of described inclined-plane and horizontal surface is 30 °.
The beneficial effects of the utility model are mainly: device of the present utility model not only can closed outdoors and open construction elevator door, can also close in door and open construction elevator door; And simple to operate, safety is secure.

Detailed description of the invention
In order to understand the utility model better, below in conjunction with embodiment and accompanying drawing, the technical solution of the utility model is described further (shown in Fig. 1-5).
A kind of locking construction elevator door gear, it comprises snap close 3, and the rearward end of described snap close 3 is provided with hand draw ring 4; Described snap close 3 bottom is provided with ("door" type) groove 8, during installation: described groove 8 is stuck in (its diapire drops on doorframe 2 upper surface) on doorframe 2, and inside the rear wall of groove 8 and doorframe 2, (i.e. elevator door close side, direction) is hinged; The leading section of described snap close 3 is inclined-plane 9, when closing door leaf 1: inclined-plane 9 is pushed in the upper end inside door leaf 1, and by inclined-plane 9 jack-up (the front end jack-up by snap close 3); When door leaf 1 cuts out completely, inclined-plane 9 falls after rise, and lower end, inclined-plane 9 (i.e. the antetheca lower end of groove 8) fastens the outside of door leaf 1 upper end.Described snap close 3 is taken the cutting of scalene square tube or is processed the shape be welded into as shown in Figure 2 with steel plate.
Described snap close 3 rear end is provided with circular hole, is inserted with rotating shaft 5 in circular hole; In described rotating shaft 5, cover has two collars, and two collars lay respectively at the both sides of snap close 3, and the described collar is fixedly connected with doorframe 2 (first by pipe link 6 and collar weld together, then being welded with doorframe 2 by pipe link 6) by pipe link 6; Described rotating shaft 5 two ends are equipped with outside thread, and outside thread place is screwed with the collar described in nut 7(between snap close 3 and nut 7, and it is too tight that nut 7 can not be twisted, and requires that snap close 3 can rotate).
The angle of described inclined-plane 9 and horizontal surface is between 15 ° to 45 °.
Described inclined-plane 9 is 30 ° with the angle of horizontal surface.Require simultaneously the hinge-point of snap close 3 and doorframe 2 (i.e. snap close 3 rotate fulcrum) to be positioned at door leaf 1 flush with inclined-plane 9 contact point or under, be preferred version.The angle changing rate that the dynamics of now closing the door and inclined-plane make is suitable.
As shown in Figure 4, when workman at closing time, snap close 3 is slowly boosted by inclined-plane 9 by door leaf 1, door leaf 1 and doorframe 2 by time (closing completely), snap close 3 i.e. reliable self gravitation effect falls automatically, by door leaf 1 fastening.When workman opens the door, draw ring 4 of shaking hands gently, snap close 3 is that is liftable, and conveniently namely the fan 1 that pushes is opened.
More than illustrate and be only Application Example of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalence change that the utility model claim is done, still belong to protection domain of the present utility model.
