Background technology
Classroom's door is for the specific a kind of convenient and practical entering house door of School Buildings structure, its feature is: daylighting multiple faults problem that is good, that frequently generally adopt simple and easy latch reduce engine tool to lock due to switch, door is generally opened towards indoor, causes potential safety hazard because have a meeting outside classroom to the student run in passageway.
But when a lot of appearance burst emergency episode, large quantities of students pours into doorway, classroom, and at this moment classroom door can be blocked, and cannot inwardly open, and result in formation of the obstruction of an escape.The design school fast-escape door is that the structure design of this situation to classroom's door has done special change: can open rotary shaft hinge (world rotary hinges) inside and outside the backflap hinge of first wife is changed into, thus realize door and can inside and outside open, and normally do not needing external-open situation Xiamen body will block a body toward external-open from a shelves bar, and shelves bar is controlled by guide rod device, pull bar design is above the pin of classroom, in case of burst dangerous situation needs emergency evacuation, student can pull pull bar that a shelves bar is backed out to reach door can toward the effect of extrapolation, can pull open latch when running into urgent dangerous situation push with regard to race, improve the time efficiency of emergency evacuation greatly.The design aims at classroom's door dangerous situation escape design, rationally reduces egress time.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of school braking bidirectional gate.
The utility model is achieved through the following technical solutions: a kind of school braking bidirectional gate, comprise a body and doorframe, door body is connected with doorframe by world rotary hinges, it is characterized in that: a grade bar is installed inside doorframe, shelves bar is arranged on a body and rotates on the doorframe of side, doorframe is hollow-core construction, doorframe offers driving hole on the side of indoor, braking bidirectional gate also comprises pushing mechanism, pushing mechanism comprises pull bar, drive link, push rod and push rod, drive link stretches in the inner chamber of doorframe by driving hole, pull bar is vertically arranged, one end that bottom and the drive link of pull bar stretch out doorframe is connected, one end that drive link stretches into doorframe is connected with push rod top, push rod is vertically arranged in the inner chamber of doorframe, a horizontally disposed push rod is connected bottom push rod, drive link and push rod connecting portion are fixed by the rotating shaft of inserting body of wall, and pushing mechanism can rotate around the shaft, the end of push rod arranges push shaft, and push shaft is connected with promotion bar, and the side sidewall being provided with grade bar at doorframe is provided with sliding tray, and promote bar is provided with connecting rod, connecting rod passes sliding tray and is connected with shelves bar.
As further improvement of these options, promote bar and be connected by three connecting rods with shelves bar, sliding tray is provided with three.
As further improvement of these options, sliding tray is curved, and the track when shape of sliding tray is moved with push shaft is identical.
The utility model has the following advantages compared to existing technology: structure is reliable, rationally reducing egress time, can improve the efficiency of emergency evacuation when running into urgent dangerous situation greatly.

Detailed description of the invention
Below embodiment of the present utility model is elaborated; the present embodiment is implemented under premised on technical solutions of the utility model; give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figures 1 to 7, a kind of school braking bidirectional gate, comprise a body 1 and doorframe 2, door body 1 is connected with doorframe 2 by world rotating shaft 46 hinge 3, it is characterized in that: inside doorframe 2, grade bar 5 is installed, shelves bar 5 is arranged on a body 1 and rotates on the doorframe 2 of side, doorframe 2 is hollow-core constructions, doorframe 2 offers driving hole 21 on the side of indoor, braking bidirectional gate also comprises pushing mechanism, pushing mechanism comprises pull bar 41, drive link 42, push rod 43 and push rod 44, drive link 42 stretches in the inner chamber of doorframe 2 by driving hole 21, pull bar 41 is vertically arranged, one end that bottom and the drive link 42 of pull bar 41 stretch out doorframe 2 is connected, one end that drive link 42 stretches into doorframe 2 is connected with push rod 43 top, push rod 43 is vertically arranged in the inner chamber of doorframe 2, a horizontally disposed push rod 44 is connected bottom push rod 43, drive link 42 is fixed by the rotating shaft 46 of inserting body of wall 7 with push rod 43 connecting portion, and pushing mechanism can 46 rotations around the shaft, the end of push rod 44 arranges push shaft 441, and push shaft 441 is connected with promotion bar 45, and the side sidewall being provided with grade bar 5 at doorframe 2 is provided with sliding tray 6, and promote bar 45 is provided with connecting rod 51, connecting rod 51 is connected with shelves bar 5 through sliding tray 6.During operation, pull back pull bar 41, drive transmission mechanism 46 to rotate around the shaft, thus promote push rod 44 and travel forward, push rod 44 by push shaft 441 promote bar 45 move forward realize grade bar 5 inside doorframe 2 on movable; The design of push shaft 441 can realize promoting bar 45 and can rotate around it, thus counteracting thrust unit rotates the rotation brought to promotion bar 45, ensures that promoting bar 45 is in vertical state all the time, thus ensures the vertical form of shelves bar 5.Under normal circumstances, in order to ensure safety, the position of shelves bar 5, by inner, blocked a body 1, a body 1 can only be opened to indoor side; When generation emergency case, when door chokes by crowd indoor, pull pull bar 41, moved by shelves bar 5 to outdoor side, thus realize door body 1 to open to outdoor side, it is unobstructed that guarantee in emergency circumstances exports.
Promote bar 45 to be connected by three connecting rods 51 with shelves bar 5, sliding tray 6 is provided with three.In order to ensure that grade bar 5 is connected with to promote between bar 45 firm, grade bar 5 can be born and clash into frequently, impact to be transferred to by the mode of connecting rod being arranged to many and to promote bar 45 by we, ensures the application life of equipment.
Sliding tray 6 is curved, and the track when shape of sliding tray 6 is moved with push shaft 441 is identical.The sliding tray 6 of arc is just in time arranged along the movement locus of connecting rod 51, and when can ensure like this to pull pull bar 41, shelves bar 5 can smooth and easyly move, and ensures the validity of emergency lower device.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
