Abstract
The utility model discloses a door for a public place, belongs to the technical field of furniture and mainly solves the problem that the door for the public place springs back too strongly and is prone to hurting people. The door for the public place comprises a door sheet and a door frame. The upper surface of the door sheet is provided with a groove; an inflation device is arranged inside the groove and comprises an inflation pipe, a piston and an air inlet, wherein the piston and the air inlet are arranged inside the inflation pipe, and the air inlet is arranged at the bottom of the inflation pipe; the outward end of the piston is hinge to a drawbar, the other end of the drawbar is hinged to a position of the door frame, which is close to the pivot, and the bottom end of the inflation pipe is connected to the end portion inside the groove, which is close to the vertical edge of the door sheet. According to the door for the public place, the door sheet can be slowly closed under the action of the inflation device, avoid strong springback and further avoid hurting people.
Description
Technical field
The utility model relates to the furniture technical field, specifically a kind of door for the public arena.
Background technology
A kind of door for the public arena is arranged, and it realizes the automatic folding of door by the rotating shaft of stretching into upper door frame ground, and people need not take any operation just can shut automatically by this behind the door, have made things convenient for going out into of people.But this shortcoming is also apparent in view, and its screen resilience is very strong, and rebound velocity is very fast, if this person back somebody will enter or go out, the door of resilience just may hindered the people of back so.
The utility model content
The purpose of this utility model is to provide a kind of door for the public arena, and the door that this kind is used for the public arena has slow resilience, inoffensive characteristics.
The technical scheme in the invention for solving the technical problem is: a kind of door for the public arena, it comprises door-plate and doorframe, described door-plate upper surface is provided with groove, be provided with an aerating device in the described groove, described aerating device comprises gas tube, is positioned at piston and the air inlet port of gas tube, and described air inlet port is positioned at the bottom of described gas tube; The hinged pull bar of a described piston end outwardly, the other end of described pull bar are hinged on the place of close rotating shaft on the described doorframe, and the bottom of described gas tube is connected in the described groove near on the end of door-plate stile.
The beneficial effects of the utility model are: when door is drawn back, piston in the gas tube outwards moves, space in the gas tube increases, air enters from air inlet port, and when door during to resilience, piston moves in gas tube, air in the gas tube is compressed, and slowly send along air inlet port, door also will slowly be shut like this, can the situation of fierce resilience not occur again.
Description of drawings
Fig. 1 is main TV structure schematic diagram of the present utility model.
Among the figure: 1 doorframe, 2 door-plates, 3 grooves, 4 gas tubes, 5 pistons, 6 air inlet ports, 7 pull bars.
The specific embodiment
As shown in Figure 1, door for the public arena of the present utility model, it realizes the folding of door by the rotating shaft of stretching into upper door frame and ground, it comprises door-plate 2 and doorframe 1, upper surface at door-plate 2 is provided with groove 3, is provided with an aerating device in the groove 3: it comprises gas tube 4, is positioned at piston 5 and the air inlet port 6 of gas tube 4, and air inlet port 6 is very little, it is positioned at the bottom of gas tube 4, also can play the effect of exhaust; The hinged pull bar 7 of an end outwardly of piston 5, the other end of pull bar 7 are hinged on the place of close rotating shaft on the doorframe 1, and the bottom of gas tube 4 is connected on the end of the stile of close door-plates 2 in the groove 3.
When door was drawn back, gas tube 4 was gradually away from the fixed end of pull bar 7 on doorframe 1, because the length of pull bar 7 can not change, so piston 5 pulled out in gas tube 4, and the spaces in the gas tube 4 increase, and air enters from air inlet port 6; When the door resilience, pull bar 7 drives piston 5 and slowly advances in gas tube 4, and the air in the gas tube 4 is compressed, slowly discharges from air inlet port 6 simultaneously, and door has also just slowly been shut.
Except the described technical characterictic of manual, be the known technology of those skilled in the art.
