Abstract
The utility model discloses an adsorption-type protection door for a construction elevator entrance, comprising a doorframe, a frame-shaped door leaf hinged on the doorframe via a hinge, wherein a door latch is not arranged on the door leaf; and a first magnet is arranged on the frame side of the door leaf and corresponding to the doorframe or the frame side of another door leaf hinged on the doorframe. According to the utility model, the magnet is arranged instead of the door latch, so that the inconvenience of opening and closing the door latch is omitted during opening and closing for the door leaf, the door leaf can be fixed on the doorframe by virtue of the magnetic force of the magnet, or two doors are mutually fixed during closing to prevent the door leaf from being automatically opened, and the door leaf can be opened in the case that a certain external force is applied. The adsorption-type protection door disclosed by the utility model is good in protection performance, convenient in use, capable of solving the safety accidents caused by that the door latch of the present protection door for a construction elevator entrance is not closed, and widely suitable for storey protection for construction elevator entrances, storey protection for material hoister entrances (gantry cranes), and protection for some large edge-approaching holes with special requirements.
Description
Technical field
The utility model belongs to door, is specifically related to a kind of absorption type construction elevator mouth protective door.
Background technology
High-story architecture construction all will use construction elevator to transport material and workman.For security needs, require protective door to be set at the place, gangway of elevator.Traditional construction elevator mouth protective door adopts metal pipe material to make, the specification disunity, and form is varied, and quality is uneven, complicacy is installed, and adopts fixedly door leaf of keeper mostly.When the protective door of this structure opened and closed, all necessary at every turn switch keeper not only bothered but also inconvenient.Some workmans usually do not use keeper that door leaf is fixed in order to follow the line of least resistance, and make protective door lose protective action.In the construction safety accident, because of the construction elevator mouth protective door protection safety misadventure that causes not in place happens occasionally.Therefore be necessary existing construction elevator mouth protective door is improved.
The utility model content
The purpose of the utility model provides that a kind of door leaf can be fixed automatically, absorption type construction elevator mouth protective door easy to use, safe.
The technical scheme that realizes the employing of the utility model purpose is following:
Absorption type construction elevator mouth protective door comprises doorframe, is hinged on the shaped as frame door leaf on the doorframe through hinge, does not establish keeper on the door leaf; The edge of said door leaf is provided with first magnet and doorframe or is hinged on the edge of another door leaf on the doorframe corresponding.
The edge of said doorframe or another door leaf is provided with corresponding second magnet of first magnet on the edge with said door leaf.
Said hinge adopts hinge of spring or common hinge.
The utility model for it, has saved the trouble of switch keeper with magnet owing to do not establish keeper during the door leaf switch; The magnetic force of magnet capable of using is fixed on door leaf on the doorframe; Two fan doors are interfixed when closing, prevent that door leaf from opening automatically, when imposing certain external force, can door leaf be opened again.The utlity model has barrier propterty preferably; Easy to use; Can solve existing construction elevator mouth protective door because of having nothing to do with the safety misadventure that keeper causes, protect adaptable across the protection of construction elevator mouth floor, the protection of material elevator mouth (gauntry crane) floor, some holes, limit of facing large-scale, specific (special) requirements.
Further specify the technical scheme of the utility model below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2, Fig. 3 are respectively the different structure scheme drawings of the utility model.
The specific embodiment
Embodiment 1
Referring to Fig. 1, the absorption type construction elevator mouth protective door of the utility model comprises metal door frame 1, is hinged on the shaped as frame single page door leaf 2 on the doorframe 1 through common hinge 4, does not establish keeper on the door leaf 2; It is corresponding with doorframe 1 that the edge of door leaf 2 is provided with first magnet 3.
Door leaf is when cutting out, and first magnet 3 on it is corresponding with doorframe 1, utilizes the magnetic force of first magnet 3 can door leaf be fixed on the doorframe 1, and the dynamics that door leaf 2 is fixed on the doorframe 1 is decided according to the magnetic intensity of magnet.When the door leaf externally applied forces is surpassed the magnetic force of magnet, can door leaf be opened.
Referring to Fig. 2, different with embodiment 1 is, the doorframe 1 of present embodiment is provided with first magnet, 3 cooresponding second magnet 5 on the edge with said door leaf 2.When door leaf 2 cuts out, second magnet, the 5 mutual adhesives on first magnet 3 on it and the doorframe 1, thereby door leaf 2 more firm the is fixed on the doorframe 1.
As shown in Figure 2, in the present embodiment, door leaf 2 adopts the double doors fan, is respectively equipped with cooresponding first magnet 3 and second magnet 5 on the relative edge of two fan door leafs 2.At closing time, two fan door leafs are fixed under the mutual adhesive effect of first magnet 3 and second magnet 5.Hinge 4 between door leaf 2 and the doorframe 1 adopts hinge of spring, after door leaf 2 is open, but door leaf 2 SELF CL under the effect of hinge of spring.
Claims (3)
1. an absorption type construction elevator mouth protective door comprises doorframe, is hinged on the shaped as frame door leaf on the doorframe through hinge, it is characterized in that not establishing on the door leaf keeper; The edge of said door leaf is provided with first magnet and doorframe or is hinged on the edge of another door leaf on the doorframe corresponding.
2. absorption type construction elevator mouth protective door according to claim 1, the edge that it is characterized in that said doorframe or another door leaf are provided with corresponding second magnet of first magnet on the edge with said door leaf.
