Abstract

The utility model relates to an automatic door closing apparatus for windows and doors, which comprises a torsion spring, a support frame and a pin shaft; both ends of the torsion spring are provided with two support legs respectively extending out of a spring body; the support frame forms a U-shaped support frame on which installation holes are arranged; both end of a U-shaped slot of the support frame are respectively provided with a pin shaft insertion base with a pin hole; the pin shaft positions the torsion spring in the U-shaped slot by the pin shaft insertion base on the support frame; two support legs of the torsion spring are respectively inserted in both sides of the support frame. The utility model has the advantages of simple structure, convenient installation, convenient maintenance, stable operation, no noise, etc., without changing the structures and connection modes of the doors and the windows.

Description

Door check

The utility model relates to the annex that uses on a kind of door and window, particularly a kind of door check.

At present, the door engine that people use is of a great variety, as swinging door hinge, tension spring, Pneumatic spring type door check and ditch spring assembly or the like, but, more than several door engines, have because structure is comparatively complicated, fragile, maintenance difficulty is big, and cost is higher, as swinging door hinge, Pneumatic spring type door check etc.; The volume that has is big, noise is bigger in the running, and easily causes damage to door, as tension spring etc.

The purpose of this utility model be to provide a kind of simple in structure, volume is little, easy to maintenance, with low cost, operate steadily muting door check.

The purpose of this utility model is achieved in that a kind of door check, comprises torque spring, support, bearing pin, and the two ends of torque spring have two supporting legs that stretch out the spring body respectively; Support is a U-shaped support, have installing hole thereon, respectively be provided with a bearing pin socket that has a pin-and-hole at the U-lag two ends of support: bearing pin is positioned at torque spring in the U-lag by the bearing pin socket on the support, and makes two supporting legs of torque spring, places the both sides of support respectively.

During use, be fixed on the utility model on the doorframe or door body of the side that the Men Tiyu doorframe is connected by support, and two supporting legs of torque spring are withstood on a body and the doorframe respectively, like this when pushing, supporting leg by torque spring makes torque spring store spring-go tension force, when the strength that pushes disappeared, torque spring discharged its spring-go tension force of storing, and by its supporting leg with door shutting slowly; Have simple in structure, easy for installation, structure and the connected mode that need not change a body and doorframe, stable, characteristics such as noiseless.And work as the utility model and use, when torque spring aging forfeiture elastic force or generation corrosion, only need to take out bearing pin because of long-term, promptly replaceable new torque spring, easy to maintenance.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described: a kind of door check, comprise torque spring 6, support 2, bearing pin 7, wherein the two ends of torque spring 6 have two supporting

legs

4,8 that stretch out the spring body respectively, respectively there is a folding leg 1 that increases Area of bearing on the top of two supporting

legs

4,8 of torque spring 6, it can play the effect of protection supporting surface, certainly, folding leg 1 also can change the back-up block that has the sheet bottom surface into; The effect of the supporting

leg

4,8 of torque spring 6 is effects of playing load, have an effect and locating; Support 2 is a U-shaped support, has installing hole 3 thereon, respectively is provided with a bearing pin socket 5 that has a pin-and-hole at the U-lag two ends of support 2; Bearing pin 7 is positioned at torque spring 6 in the U-lag by the bearing pin socket 5 on the support 2, and makes two supporting

legs

4,8 of torque spring 6 place the both sides of support 2 respectively.

During use, as Fig. 2, Fig. 3, shown in Figure 4, the utility model is fixed on the doorframe 9 or door body 10 of the side that a body 10 is connected with doorframe 9 by support 2, and two supporting

legs

8,4 that make torque spring 6 withstand on respectively on a body 10 and the doorframe 9, like this when pushing, supporting

leg

8,4 by torque spring 6 makes torque spring 6 store spring-go tension force, when the strength that pushes disappears, torque spring 6 discharges its spring-go tension force of storing, and the synergy by supporting

leg

4,8 is with door shutting slowly; As shown in Figure 3, when being installed in the utility model on the timber, available screw is installed in the utility model on the surface of the doorframe 9 between a body 10 and the doorframe 9 by the installing hole on the support 23, and supporting

leg

8,4 withstood on respectively on a body 10 and the doorframe 9: as Fig. 4, shown in Figure 5, in the time the utility model will being installed on the steel casement door window, can be with support 2 by welding or riveted way, be fixed on the external surface of the surface of a body 10 or doorframe 9, supporting

leg

8,4 withstood on respectively on a body 10 and the doorframe 9 get final product then.In addition, if the door body is heavier, when the resistance of closing the door is big, a plurality of the utility model can be installed between a body and the doorframe in uniform mode and gets final product.
