Enhanced buckle

Abstract

The invention provides an enhanced buckle, and relates to the field of sheet metal connection. The enhanced buckle comprises a V-shaped top plate, wherein vertical buckle plates are connected to two sides of the top plate, the bottoms of the two buckle plates are connected through a horizontal transverse plate, the transverse plate is connected to the lower parts of the buckle plates, and outer buckle elastic sheets are connected to the side surfaces, far away from each other, of the two buckle plates. When the buckle is designed, a wide and thick design structure of the main body part is canceled, so that the shrinkage risk in the buckle injection molding process is reduced; an elastic design scheme of a buckle blade is canceled and is embodied by the outer buckle elastic sheets perpendicular to the assembling direction, so that the requirement on the height of a metal plate in the buckle mounting process is reduced; in order to guarantee structural implementation, the transverse andlongitudinal size design needs to be matched with the size of the buckle hole, on the premise that the insertion and extraction force of the buckle is guaranteed, the use amount of nylon materials isreduced, and meanwhile the anti-rotation requirement of parts is met.

Description

technical field [0001] The invention relates to the field of sheet metal connection, in particular to a reinforced buckle. Background technique [0002] Existing buckle design patterns, such as figure 1 As mentioned above, relying on the main part matching the buckle size, the buckle blades are extended on both sides to facilitate the connection of the part assembly and the sheet metal. [0003] However, during the processing and use of this structural buckle, there are the following risks: 1. During the injection molding process, the buckle is prone to shrink in size due to the excessive amount of material used in the main part, and cannot match the sheet metal hole normally, resulting in buckle 2. In the process of matching and installing this type of buckle with the sheet metal hole, the height of the sheet metal gap required is relatively large, and the requirements for the application environment are high, and it cannot be matched in many places where the gap between t...

[0003] However, during the processing and use of this structural buckle, there are the following risks: 1. During the injection molding process, the buckle is prone to shrink in size due to the excessive amount of material used in the main part, and cannot match the sheet metal hole normally, resulting in buckle 2. In the process of matching and installing this type of buckle with the sheet metal hole, the height of the sheet metal gap required is relatively large, and the requirements for the application environment are high, and it cannot be matched in many places where the gap between the outer plate and the reinforced version is small Use; 3. This kind of buckle blade, due to the elastic requirements of installation, the thickness of the blade is limited
