Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-4, the present embodiment provides a damping device for doors and windows, including a door and window frame 1, wherein a yarn box shell 2 is fixedly installed on one side of the door and window frame 1, a yarn winding shaft 3 is arranged in the yarn box shell 2, and a clamping groove for installing a damping device body is formed in one end of the yarn winding shaft 3;
The damping device body comprises a damping piece 4, a first connecting piece 5, a second connecting piece 6 and a short-distance torsion spring 7, wherein end covers 8 are detachably and fixedly connected to two sides of the yarn box shell 2, the first connecting piece 5 and the second connecting piece 6 are respectively and fixedly connected with two ends of the short-distance torsion spring 7, the other end of the first connecting piece 5 is fixedly connected with the outer wall of one end cover 8, the other end of the second connecting piece 6 is fixedly connected with the damping piece 4, and the other end of the damping piece 4 is fixedly connected with the inner wall of the clamping groove;
Wherein the other end of the yarn winding shaft 3 is rotatably connected with the other end cover 8.
The working principle is as follows: when the screen window (door) is reset, the winding reel 3 rotates and drives the damping piece 4 to rotate and deform with the short-shaft torsion spring, the damping piece 4 is indirectly connected with the yarn box shell 2 through the short-distance torsion spring 7 and the end cover 8, when the winding reel 3 rotates and returns, the front-stage torque of the return stroke is high, the damping piece 4 is high in speed, the short-distance torsion spring 7 is forced to work, when the winding reel 3 returns to the middle position, the short-distance torsion spring 7 is locked, the damping piece 4 starts to slowly rotate at the moment, the return stroke speed of the winding reel 3 is slowed down, the latter half section is slowly closed due to the speed reduction of the screen window (door), the mute effect is generated, the door and window frame 1 is prevented from being deformed due to collision, the return stroke speed of the front-stage short-distance torsion spring 7 is not too slow, the waiting time is reduced, and the practicality of the screen window (door) is ensured.
In order to facilitate the normal use of the rolling screen window, the surface of the rolling screen shaft 3 is provided with a screen 9, one end of the screen 9 is fixedly connected with the outer wall of the rolling screen shaft 3, and the other end of the screen 9 is fixedly connected with a handle 10;
The yarn case shell 2 is close to the reservation groove that supplies yarn net 9 activity has been seted up to one side outer wall of door and window frame 1, pulls handle 10 during the use, can make yarn net 9 come out from in the yarn case shell 2 to accomplish to seal to cover door and window frame 1, and can drive the reel 3 and rotate when yarn net 9 comes out from in the yarn case shell 2, make things convenient for the normal use of rolling up curtain screen window.
Considering the stability that needs to guarantee when handle 10 drives the screen window to seal door and window frame 1, so door and window frame 1's both sides inner wall has all been seted up and has been supplied the gliding spout of handle 10, when pulling handle 10 and remove, the spout can make the restriction to the removal of handle 10, guarantees the stability when handle 10 drives the screen window and removes.
In order to ensure the return speed of the yarn winding shaft 3, the other end of the yarn winding shaft 3 is provided with a reserved groove for installing the yarn winding shaft torsion spring 11, two ends of the yarn winding shaft torsion spring 11 are fixedly connected with the inner wall of the reserved groove and the outer wall of the other end cover 8 respectively, and when the yarn winding shaft is used, the yarn winding shaft 3 is driven to rotate and return at the initial stage by the yarn winding shaft torsion spring 11, and is blocked by the short-distance torsion spring 7 to be quickly recovered, at the moment, the damping piece 4 does not play a buffering role, and the rotating speed of the yarn winding shaft 3 at the initial stage of the return can be ensured.
The effect of screen 9 rolling is guaranteed in the operation, so damping piece 4 cooperatees with the minor axis torsional spring, accomplishes the secondary buffering when screen 9 rolling, and when carrying out screen 9's rolling, damping piece 4 cooperatees with the minor axis torsional spring, can make when reel 3 carries out the rolling, carries out twice different buffering for reel 3 rolling early speed is fast, and the rolling later speed is slow, guarantees the effect of screen 9 rolling.
In a specific use, a damping device for a door or window of the present embodiment is first: the user pulls handle 10 for reel 3 rotates, and drive damping piece 4 and reel torsional spring 11 rotation deformation, and make gauze 9 shelter from door and window frame 1, when needs gauze 9 reset, drive reel 3 return stroke under the elasticity effect of reel torsional spring 11, when the high speed fast damping piece 4 damping of return stroke early moment, force short-distance torsional spring 7 work, when reel 3 return stroke to intermediate position, short-distance torsional spring 7 locking, reel torsional spring 11 continues to drive reel 3 and carries out the return stroke, simultaneously damping piece 4 begins to work, make the return stroke speed of reel 3 slow down, the latter half of return stroke is because reel 3 rotation speed descends, screen window (door) slowly closes, produce the silence effect, and screen window (door) quick closure produces great collision when can not, influence the life of screen window (door).
The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be understood by those skilled in the art that the present utility model is not limited to the above-described embodiments, and that the above-described embodiments and descriptions are only preferred embodiments of the present utility model, and are not intended to limit the utility model, and that various changes and modifications may be made therein without departing from the spirit and scope of the utility model as claimed.
