Abstract
The utility model belongs to a speed adjusting device for opening or closing a door, a window or a wing, particularly a door or window damper which can reduce the speed when the door or window is opened or closed. The utility model comprises a movable part and a fixed part. The utility model is characterized in that the movable part comprises a piston cylinder body, a piston and a piston rod, the end part of the piston cylinder body is provided with a small air gate, the fixed part comprises two rotatable fixed heads which are respectively installed on the door or window and a door or window frame, wherein a door rotatable fixed head which is fixed on the upper edge of the door or window is connected with the piston rod and a frame rotatable fixed head which is fixed on the upper edge of the door or window frame is connected with the piston cylinder body. The utility model can reduce the speed for opening or closing the door or window, violent impact can not happen under heavy wind and the door can not be destroyed. The utility model has the advantages of simple structure and convenient installation and operation. The utility model can be widely used for various wings, doors and windows.
Description
Technical field
The utility model belongs to the speed adjusting device of door, window or wing closure or openness, particularly relates to a kind of door and window snubber.
Background technology
Strong wind or human factor all may be opened door and window fiercely or shut, and send huge sound, influence that people have a rest even door is broken, though existing various door holders, if but strength is excessive or excessive velocities, then door holder can't be fixed door and window, still can cause noise or infringement.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the utility model provides a kind of door and window reducer that can reduce its speed when Switch for door and window.
The technical solution of the utility model is as follows: the door and window reducer, comprise movable and fixing two parts, feature is that its movable part comprises that the end is provided with piston/cylinder and the piston and the piston rod of a little valve, standing part comprises that two of being installed in respectively on door and window and the doorframe and window frame can be rotated with and decides head that the door that wherein is fixed on the door and window upper edge can be rotated with fixed head and be connected with piston rod; The frame that is fixed on the doorframe and window frame upper edge can be rotated with fixed head and be connected with piston/cylinder.
Said being rotated with of installing respectively decided head, respectively is provided with an axle, and the one end is fixed on door and window or the doorframe and window frame, and the other end is separately fixed on piston rod or the piston/cylinder.
Said cylinder body length be bar wide 1/2nd, its length and cylinder body equal in length when piston rod stretches out fully.
Operating principle is: piston rod is fully in the cylinder body the inside when door is closed, and piston rod will be drawn out when door is opened fast, and the cylinder body internal gas pressure is reduced, and air will enter cylinder body by little valve; When door during by quick closedown piston rod want retract cylinder, the cylinder body internal gas pressure is increased, gas will be got rid of from stingy door; Because little valve is very little, so, all can reduce the speed of door, thereby reach the purpose that door and window changes down the pass slowly by piston, piston rod no matter be to close door and window or door window; And, the speed that the size by regulating little valve can indirect regulation switch door and window.
Can the slow down speed of switch door and window of the utility model door and window reducer even wind greatly can not clash yet, more can not break door.The utility model is simple in structure, and is easy to install and use, can be widely used in various fan door and windows.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model standing part scheme of installation;
Among the figure: 1. piston rod, 2. piston, 3. piston/cylinder, 4. little valve, 5. frame can be rotated with fixed head, 6. can be rotated with fixed head, 7., 8. doorframe.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Structure as depicted in figs. 1 and 2, present embodiment is used for the switch of door, by movable and fixedly two parts form, movable part comprises that the end is provided with piston/cylinder 3 and the piston 2 and the piston rod 1 of a stingy door 4, standing part comprises that two of being installed in respectively on door and the doorframe can be rotated with fixed head (pivoting), wherein is fixed on a door at middle part, upper edge and can be rotated with and decides 6 and be connected with piston rod 1; Be fixed on the doorframe upper edge, can be rotated with fixed 5 near the frame of door hinge and be connected with piston/cylinder 3, be fixed on piston/cylinder 3 close ends above.
Two install respectively be rotated with fixed 5,6, respectively be provided with an axle, axle one end that its center can be rotated with fixed 5 is fixed on the doorframe 8, the other end is fixed on the piston/cylinder 3; Axle one end that door can be rotated with fixed 6 is fixed on the door 7, and the other end is fixed on the head of piston rod 1.Fixed head can be rotated with and also other rotation and fixed form can be adopted.
Present embodiment piston/cylinder 3 length are 45 centimetres, and diameter is 3.5 centimetres, length and cylinder body equal in length when piston rod 1 stretches out fully.
Claims (3)
