Abstract
The utility model provides a device which utilizes compressed air to prevent a house door from opening and closing quickly and fiercely. The utility model is mainly composed of an air pump, a front cover, a rear cover, a valve cover, a piston, etc. The utility model can effectively resist the impact generated due to air convection to the house door in the building and ensure the personal safety and ensure that the object is free from being broken. The utility model avoids the unexpected accidents and the unnecessary troubles appearing in the people's daily life and can not affect the normal opening and closing of the door for the people.
Description
The utility model relates to a kind of device that prevents quick, the fierce switch of door.
In building, open door and window, cross-ventilation and produce air stream, door is impacted, make its fast, switch fiercely, except sending the very big sound, damaging the building, for putting the object and the person that is held in (or hiding behind the door) between door and the doorframe accidentally, will damage and wound.For fear of these unsafe factors, need constantly switch door and window modestly, way control gate such as adopt that rope draws, do not make its fast, switch fiercely.
Task of the present utility model provides a kind of snubber, prevent door fast, switch fiercely, but for the normal switch door of people, then unaffected.
Structure of the present utility model is such.As shown in drawings, inflator (1), be threaded between protecgulum (2) and the bonnet (3) and be integral, be fixed on the doorframe and (do not draw among the figure), be drilled with several apertures around protecgulum (2) centre bore, piston (4) is positioned at inflator (1), be embedded with apron (5) on the head end disk, its centre bore that passes protecgulum (2) stretches out with door (not drawing among the figure) and links to each other, Pi Huan (6) is fixed on around bonnet (3) aperture and the shoulder hole, valve gap (7) is connected on the bonnet (3) with the hinge form, the other end is supported by the fore-set (8) that is through in bonnet (7) shoulder hole, and little spring (9) is enclosed within on the fore-set (8).
Task of the present utility model is finished like this.When air-flow produce to impact door, force its fast, switch fiercely.When door was closed, door promoted piston and advances fast, the air in the extruding inflator, air produces extruding to valve gap, when its power during greater than the power of compression little spring, and valve gap compression little spring, depress pillar, and be close to the skin ring, form sealing, along with the continuation propelling of piston, extruded air increases in the inflator, when its power equals the thrust of piston, just stop piston to advance, thereby door is stopped operating.Like this, leave certain distance between door and the doorframe, played the safeguard protection effect.When people normally at closing time because speed is slow, piston advances slow, the extruding force that air produces in the inflator is less than the power of compression little spring, makes valve gap can not depress pillar and forms sealing with the skin ring, like this, air is then discharged from the aperture of bonnet.Make door when opening, a door body spurs piston fast, makes the air between piston and the protecgulum form extruding, and the air of extruding appears from the aperture of protecgulum, forces piston slowly to move, like this, just stoped door fast, open fiercely.When people's normal door, piston traveling speed is slow, the air between piston and the protecgulum is released from the aperture of protecgulum and is not produced extruding, therefore, does not influence people's normal door.
Claims (1)
- A kind of door snubber is made up of inflator (1), protecgulum (2), bonnet (3), piston (4) and valve gap (7) etc., it is characterized in that:Be drilled with several apertures around the centre bore of a, protecgulum (2),B, piston (4) are positioned at inflator (1), are embedded with apron (5) on the head end disk, and its centre bore that passes protecgulum (2) stretches out,C, valve gap (7) hinge form are connected on the bonnet (3),D, skin ring (6) are fixed on around the aperture and shoulder hole of bonnet (3),E, fore-set (8) are through in the shoulder hole of bonnet (3), and head end is supporting an end of valve gap (7),F, little spring (9) are enclosed within on the fore-set (8).
