Glass door floor spring capable of being opened and closed by 360 degrees

Abstract

The invention belongs to the technical field of glass door floor springs, and particularly relates to a glass door floor spring capable of being opened and closed by 360 degrees. The glass door floorspring comprises a door frame and a glass door. In the opening process of the glass door, under the action of a gear and a rack, the glass door can slide relative to the door frame to move inwards oroutwards and finally is attached to the side face of the door frame, the occupied space of the glass door after being opened is reduced, especially for a door close to a street, after the door is opened, the potential safety hazards of the glass door to passing pedestrians and vehicles are reduced, and meanwhile the glass door is protected. According to the glass door floor spring, the minimum section of internal circulation of a flow guide groove is adjusted by adjusting the length of a damping screw rod in the flow guide groove, then the resistance in the sliding process of a piston is adjusted, the rotating resistance of a cam can be adjusted by adjusting the damping screw rod, then the resistance of the glass door in the opening and closing process is adjusted, and the longer the length of the damping screw rod in the flow guide groove is, the larger the damping force is.

Description

[0001] Technical field [0002] The invention belongs to the technical field of glass door floor springs, in particular to a 360-degree switchable glass door floor spring. Background technique [0003] The floor spring is a hydraulic door closer, except that the device that compresses the spring is a cam instead of a rack and pinion. Because the cam can rotate forward and reverse, the floor spring can be used for doors that open in both directions. [0004] At present, the opening angle of the floor spring is about ±110 degrees instead of ±180 degrees; there are two main reasons for this: [0005] First, the design of the floor spring itself does not consider reaching ±180 degrees. [0006] Second, because the door frame has a certain thickness, after the door is opened to approximately ±180 degrees, the door will collide with the door frame and interfere, and the door frame restricts the opening of the door. [0007] Doors installed through existing floor springs have the ...

Problems solved by technology

[0005] First, the design of the floor spring itself does not consider reaching ±180 degrees

[0006] Second, because the door frame has a certain thickness, when the door is opened to close to ±180 degrees, the door will collide with the door frame, and the door frame will limit the opening of the door

[0008] First, after the door is opened, whether it is opened inward or outward, it needs to occupy a certain amount of space

[0009] Second, for doors close to the street, after opening, there are certain safety hazards for passing pedestrians and vehicles, and it is easy to hurt passing pedestrians or vehicles, and the door will also be damaged after being hit.
