High-strength G-shaped fastening piece and fastening structure

Abstract

The invention relates to a high-strength G-shaped fastening piece and a fastening structure. The G-shaped fastening piece comprises a locking edge fastening piece and a locking tongue-and-groove fastening piece, and the locking edge fastening piece and the locking tongue-and-groove fastening piece are all equal to the length of a connecting face; one side of the locking edge fastening piece is provided with a locking edge connecting part connected with an object I, the other side of the locking edge fastening piece is provided with a G-shaped locking edge buckling part, one side of the lockingtongue-and-groove fastening piece is provided with a locking tongue-and-groove connecting part connected with an object II, the other side of the locking tongue-and-groove fastening piece is providedwith a G-shaped locking tongue-and-groove fastening part, and the G-shaped locking edge buckling part and the G-shaped locking tongue-and-groove fastening part are relatively rotated by buckling. According to the high-strength G-shaped fastening piece and the fastening structure, the fastening piece can replace a traditional hinge to realize the rotating connection of the door and window, the fastening piece are equal to the length of the connecting face, the fastening piece and the connecting face can be integrally formed, the stress at the joint is evenly distributed along the connecting face, the structural strength is high, and breakage is not easy; the G-shaped structure is specially designed with three cable points for forming a triangular structure, the fastening piece does not break, the G-shaped design also has a waterproof effect, and the rainwater is prevented from entering the room from the connection.

Description

technical field [0001] The invention relates to a fastening piece for realizing rotational connection between objects, in particular to a high-strength G-shaped fastening piece and a fastening structure. Background technique [0002] Fasteners are usually used to realize the movable connection between objects. The structural design of the fastener directly affects the stability of the connection between objects, because the place where the fastener is located is the concentrated point of stress. If the structural design is unreasonable, it is easy to It causes stress concentration at the stress point, which reduces the connection strength between objects, and there is a risk of detachment. Especially the hinges that play a connecting role at the joints of doors and windows, once they break or fall off, it will directly affect personal safety.

Problems solved by technology

[0002] Fasteners are usually used to realize the movable connection between objects. The structural design of the fastener directly affects the stability of the connection between objects, because the place where the fastener is located is the concentrated point of stress. If the structural design is unreasonable, it is easy to Cause stress concentration at the stress point, reduce the connection strength between objects, and cause the risk of detachment

Especially the hinges that play a connecting role at the joints of doors and windows, once they break or fall off, it will directly affect personal safety.

[0003] The traditional hinge is fixed with the connecting object through the lug plate, and the two lug plates are connected by the rotation shaft. Due to the limited length of the lug plate of the traditional hinge, it is usually necessary to install multiple hinges on the connecting surface, such as on the upper part of the door panel The traditional hinge structure can only realize the local area connection of doors and windows, so that the stress point is concentrated on the hinge shaft. If the strength of the hinge is not enough, it is easy to cause the problem of doors and windows falling off.

Moreover, due to the existence of the rotating shaft in the traditional hinge connection structure, there is a gap at the joint between the door and the window, and rainwater easily enters the room along the gap. The traditional hinge does not have the function of waterproofing, nor does it have sound insulation effect. It will also enter the room through the gap at the connection
