Novel door and window damping limiting wind brace

Abstract

The invention relates to a novel door and window damping limiting wind brace which is equipped with a fan fixing part, a frame fixing part and a wind brace main body, wherein the wind brace main body is equipped with a wind brace outer pipe; one end in the wind brace outer pipe is equipped with a damping fixing part; an inner cavity is arranged in the middle of the damping fixing part; a cone-shaped damper is arranged in the inner cavity; an expanding-shrinking cavity is arranged in the damper body; a drawbar is arranged at the inner end of the damper; a damping gear block is arranged between the drawbar and the wind brace outer pipe; one end, connected with the damper, of the drawbar is equipped with a damping pressure spring which is tightened between the damping gear block and the damper; the other end of the drawbar is connected with the fan fixing part; and the outer end of the damping fixing part is connected with the frame fixing part. The novel door and window damping limiting wind brace is suitable for being used as the damping limiting wind brace of doors and windows as well as other wind-driving opening-closing equipment, can generate very gentle buffer effect to prevent doors and windows from being fiercely opened, closed and collided; doors and windows can be stabilized on each position, so that the doors and windows are protected very well; and the novel door and window damping limiting wind brace is convenient to use, is convenient and flexible to mount, and can greatly prolong the service lives of the doors and windows.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a damping limit wind brace used on doors, windows or other equipment. Safety features of other devices. The invention is suitable for doors, windows or other switchgears that may be blown by wind, and has novel structure, firm installation, good performance and wide application range. Background technique [0002] Doors, windows and other devices that are easily blown by the wind often produce excessive switching action due to excessive wind force or artificial switching force, which is prone to loud noises, violent collisions, and even damage to doors and windows or damaged. Existing doors and windows are all provided with a connection structure that connects the door and window sash and the door and window frame, but few doors and windows are connected by a damping structure, and most of the existing damping structures are more complicated, larger in size, and ...

Problems solved by technology

[0002] Doors, windows and other devices that are easily blown by the wind often produce excessive switching action due to excessive wind force or artificial switching force, which is prone to loud noises, violent collisions, and even damage to doors and windows or damaged

Existing doors and windows are equipped with connection structures that connect the door and window sash and the door and window frame, but few doors and windows are connected by damping structures, and most of the existing damping structures are more complicated, larger in size, and the effect is often not ideal

In particular, the existing common damping structure generates damping force through slide rails and sliders, and the doors and windows are fixed by hand-tightened screws. The damping structure is very easy to wear and needs to be replaced frequently, resulting in high cost of use.
