Abstract

A door closer with a damper is composed of a movable fixed seat (1), a static fixed seat (2), a tension spring (3), a sliding rod (4) and an air damper. One end of each of the two sliding rods is riveted with the fixed fixing seat and can rotate, the other end of each of the two sliding rods is fixed with an upper cover (5) of the damper through a screw, a sliding groove is formed in the middle of each of the two sliding rods and can be clamped on the flat tenons at the two ends of the rotating shaft (7) to slide back and forth, the elastic force of the spring is applied to the door, and partial power of the door is converted into the pulling pressure on the damper along with the opening and closing of the door. The air in the telescopic cavity is blocked when being pressed to pass through the air nozzle (8), so that the damper generates a force opposite to the power direction of closing the door to reduce the rotating speed of the door, and the aim of gently and slowly closing the door is fulfilled.

Description

Damping device for closing door

The utility model relates to a kind of accessories for windows and doors, particularly a kind of door closer with damper.

The door of hotel and family can not be closed automatically at present, and it is not too convenient to close with hand, runs into strong wind weather, and wind-force can make the door quick closedown of holding and produce very big sound, also can reduce the application life of door simultaneously.

The damping door closer that the purpose of this utility model is to provide a kind of installs easily, effort to close can be regulated, the sound of closing the door is very little.

The purpose of this utility model realizes by following technical proposal: door closer is made up of moving holder (1), quiet holder (2), tension spring (3), slide bar (4), air damper.Sound two holders can be respectively with on the screw on door and doorframe.One end of slide bar and quiet holder riveted joint and rotatable, the loam cake of the other end and damper (5) is fixed with screw, a chute is opened at the middle part of slide bar, may be stuck on the flat tenon at rotating shaft (7) two ends and slidably reciprocate, the elastic force of spring is applied on the door, Sui the switch of door, and the part power of door is converted into pressure to damping cavity, the velocity of rotation of limiting door.Damper bottom (6) is connected with rotating shaft, and the flat tenon of rotating shaft slides in the chute of slide bar and guaranteed the parallel of two lids of damper.The main body of damper is a software telescopic cavity (9), has covered a gas on it and has chewed (8), the size in the screw that gas is chewed is adjustable solar term hole.Because pore is smaller, the air in the air chamber can be hindered when extruding, and reduces the velocity of rotation of door so damper can produce a power opposite with the power direction of closing the door, the purpose that reaching closes the door treats without proper respect.On covered a breather cheek valve (cover out a hole, valve is exactly the soft limit of rubber of damping cavity), do not produce resistance when opening the door.The axis that the stress point of quiet holder upper spring is positioned at rivet is outer slightly, like this, the stressed dead point of door is positioned at the position less than 90 degree, so door reached by the position of wall just crossed the dead point, elastic force then forwards on the direction of opening the door, door just can not closed, and promptly door reaches maximum position and just can not close automatically.Like this, remove when what thing is want Men Kaida is not related to and just seem very convenient.

Fig. 1 is a vertical view of the present utility model.

Fig. 2 is a front view of the present utility model.

Fig. 3 is that gas is chewed the sectional view with breather cheek valve

Fig. 4 is the front view and the vertical view of rotating shaft.

That this utility model has is simple in structure, easy for installation, close the door and treat, have during Men Kaida the characteristics such as stable state without proper respect.

The stressed member of this utility model all is rolled-up stock, and the steel plate compacting of available 2mm forms, and damping cavity is made with rubber, handling ease, and cost is low.

Claims
