Abstract
The utility model relates to an automatic door-closing device. The utility model is provided with an air barrel and a piston which can slide in he air barrel, wherein, a return spring is arranged between the piston and the front end plug of the air barrel, and the rear end plug of the air barrel is provided with an adjustable air lock; furthermore, energy is consumed through utilizing compressed air so as to realize the purpose of deceleration. The utility model has the advantages of lower speed and safe use; noise is not generated when a door is closed; besides, because the utility model has a positioning device, the open position of the door can be adjusted, and people who push cycles, the handicapped, etc. conveniently enter and go out from a room through the door.
Description
The utility model relates to a kind of closing device, particularly a kind of door engine.
Existing closing device, general all by the spring realization, camber of spring when promptly opening the door utilizes the elastic force of spring that door is closed automatically after loosing one's grip.But this mode general speed of closing the door is very fast, not only loud, and restoring force is also big, hurts sb.'s feelings easily, particularly child.
The purpose of this utility model is the above-mentioned shortcoming that will overcome the conventional springs door closer, and a kind of door engine that damping is arranged is provided, and makes safer, the convenience of closing the door.
Solution of the present utility model is: the piston that can slide relatively is set in an inflator, and the front end of pitch brace is connected with door, and the rear end of inflator is connected with doorframe.Between the preceding plug of piston and inflator, back-moving spring is housed, on the back plug of inflator, adjustable vapour lock is housed.
Adjustable vapour lock on the back plug can be the air gap between screw, the nut.
The set screw that a control gate opening angle is arranged on the preceding plug.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the longitudinal sectional view of door check.
Fig. 2 is the user mode figure of door check.
Referring to Fig. 1, a piston 6 is arranged in inflator 2, piston 6 links to each other by hold-down nut 13 with pull bar 3.The other end of pull bar 3 has front rotary shaft hole 5, and it is connected with the front axle stator 14 usefulness screws of door on 17, thereby the front end of pull bar 3 is linked to each other with door 17.
Back-moving spring 1 is housed between the plug 10 before piston 6 and inflator.One back shaft hole 4 is arranged on the rear axle stator 5, link to each other with doorframe 16 by screw.Adjustable vapour lock 8 is arranged on the back plug 9, and adjustable vapour lock 8 is to regulate vapour lock by the air gap between screw, nut among the figure.A set screw 7 is arranged on the preceding in addition plug 10, can be used to the angle that adjustment doors is opened.Preceding plug 10 is fixing by fixed screw 11.
Referring to Fig. 2, this device adopts the flexible member energy storage, and compressed air consumes energy, and reaches the purpose of deceleration.When opening the door, pull bar 3 is pulled out in cylindrical shell 2, and air is inhaled into air storage chamber 12, and spring 1 is compressed.As door being located, can finish by screwing set screw 7.At closing time, under the effect of spring force, pull bar 3 is return, and the air in the cylindrical shell 2 is compressed, and discharges gradually by adjustable vapour lock 8, forms damping, the kinetic energy of door 17 is reduced, thereby play cushioning effect.The depth-adjustment solar term resistance that set screw screws in, thus the speed of closing the door changed.
This door closer is owing to there is adjustable vapour lock, so the speed of closing the door is slower, do not hit the person, tong, safe in utilization not, and do not have the big sound, and is easy for installation.Because positioning equipment is arranged, be fit to take thing and trammer, disabled person's inlet/outlet in addition.In a single day reserve the position that door is opened, and mechanical forces such as natural wind all can not make the enable possition of door change, and are safe and reliable.
