Abstract
The present invention relates to an opening and closing device for a wing sash, which comprises an oscillating rod, a front supporting base and a back supporting base thereof, wherein the oscillating rod is composed of a pipe body, a regulating rod, a tension spring and a buffer; the regulating rod is positioned in the pipe body and connected with the front cover of the pipe body by screw nails; the tension spring is connected with the regulating rod, and the back end of the tension spring is provided with back hooks; the oscillating rod is fastened with the back supporting base by the hooks arranged at the back part of the tension spring; the front supporting base is provided with a fixed slide rail which can be regulated in a vertical direction and a transverse direction; the front end of the oscillating rod is movably fixed in the slide rail of the front supporting base by screw bolts. The present invention has the advantages of compact structure, small size and no noises; the present invention can be fixed above the root of a door, so the other space is not occupied; the present invention can not cause damage to the door for long-term use.
Description
The present invention relates to unlatching, the closer of wing.
In people's daily life,, usually wish that the automatic device that produces effect can help it to close the door automatically especially in winter.Entered epoch of average family at current air-conditioner, automatic door closer shows especially and needs, and it can be closed the door with the epoch people, stops the indoor and outdoor cross-ventilation, and it is constant not only can to keep indoor air temperature, but also can play dustproof, noiseproof, antitheft effect.
Just, present existing piston type door closer, as shown in Figure 1, connecting forward and backward holder 1-5,1-1 by swing arm forms, swing arm comprises that one places stage clip, the piston in the body and stretches out the body head and piston rod 1-4 that holder joins, be located at body afterbody and the adjusting lever that the back holder joins, the powerful elastic force that relies on stage clip promotes piston rod closes door.Also have a kind of mouse tail formula door closer, also connect forward and backward holder and form by a swing arm, its action of closing door be by place the button of torsion spring in the holder of back try hard to recommend moving join with it swing arm realize.Described two kinds of door closers, its of its existence with weak point is: 1, when installing and using, the back holder of door closer is fixed on the doorframe, front end can only be fixed on the middle part of door, because existing office, residential occupancy mostly are the timbers of being made by three-ply board, pushed by the brute force of the preceding holder of door closer, damage easily; 2, because back holder volume is bigger, be difficult to install for the other less house of leaving a blank of doorframe; 3, because the long-term switch of door, hinge suffers big twisting force, causes distortion easily.
The object of the present invention is to provide that a kind of compact conformation volume is little, elegant in appearance, noise is little, easy to install, the lamp tube type noiseless door closer of fragile door-plate not.
The present invention realizes like this, lamp tube type noiseless door closer, comprise swing arm and forward and backward bearing thereof, swing arm by body, place in the body adjusting rod that the protecgulum by screw and body joins, the extension spring snubber that joins with adjusting rod, the extension spring of rear end band aft hook form, swing arm is by the hook and the rear support snapping at extension spring rear portion, before bearing be provided with can upper and lower left and right adjusting fixed rack, the front end of swing arm is active be fixed on before in the slide rail of bearing.
Advantage of the present invention is: compact conformation, draw bullet owing to adopt, cause volume less, but, realizes the fixed rack that the pass closed system of door is regulated by the upper and lower, left and right of preceding bearing setting because reaching a swing arm that is connected with door, reduced the friction between parts, reduced noise, because its forward and backward bearing is fixed in a upper end and doorframe top, do not take up space in addition, and long-term use can not damage door-plate; After door closer of the present invention is installed on the door, far see the 8W fluorescence lamp of a flash of light of picture, give indoor modish decoration result and the natural and unrestrained elegance of having increased simultaneously.
The following drawings and embodiment will be described further technical characterictic of the present invention:
Fig. 1 is the structure chart of existing piston type door closer.
Fig. 2 is the structure chart of existing mouse tail formula door closer.
