Description

Technical Field

[0001] This utility model relates to the field of sheet metal connection technology, specifically to a precision sheet metal part connection and reinforcement structure. Background Technology

[0002] Sheet metal parts are characterized by their light weight, high strength, electrical conductivity, low cost, and good mass production performance. They are widely used in fields such as electronics, communications, automotive, and medical devices. Currently, the connection between sheet metal parts is usually installed using two bolts. After being shaken, the bolts connecting the parts are prone to loosening, resulting in unstable connections between the sheet metal parts, which requires reinforcement.

[0003] A search revealed that patent application CN219587918U discloses a precision sheet metal connection reinforcement structure, comprising a symmetrically distributed first sheet metal part and a second sheet metal part. A reinforcement frame is fixedly provided on one end of the first sheet metal part facing the second sheet metal part. A connecting component is provided between the reinforcement frame and the second sheet metal part. A locking block is inserted into a locking groove, thereby completing the first layer of connection between the first sheet metal part and the second sheet metal part. A rotating wheel drives a screw to rotate, causing a push plate threaded onto the screw to push a stop rod into the first stop groove on the locking block. The installation is simple and convenient, facilitating the connection of sheet metal parts.

[0004] However, for thin sheet metal, the use of slots at the joints and plug-in connections can easily lead to breakage at the joints, resulting in low connection strength. Additionally, the use of a set of screws for connection results in low stability and an unstable connection.

[0005] Therefore, we propose a precision sheet metal connection reinforcement structure. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a precision sheet metal connection reinforcement structure, which solves the problems of low connection strength and low stability in existing devices.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a precision sheet metal connection and reinforcement structure, comprising sheet metal A and sheet metal B;

[0008] The connection between sheet metal A and sheet metal B is equipped with two sets of matching connectors. The top surfaces of sheet metal A and sheet metal B are respectively provided with two sets of through holes in opposite positions. The inner side of the connector is provided with a groove in matching size. The outer side of the connector is provided with two sets of mounting holes B in opposite positions and penetrating through. The mounting holes B are equipped with matching limiting threaded anchor rods.

[0009] The top surface of the connector has two sets of mounting holes A that are opposite to the through holes and are of the same size. A limiting screw of the same size is installed in the mounting hole A. A nut A is fixedly installed at the top of the limiting screw. A nut A of the same size is installed on the outer wall of the limiting screw. A nut B of the same size is fixedly installed at the right end of the limiting threaded anchor rod. A nut B of the same size is installed on the outer wall of the limiting threaded anchor rod.

[0010] Preferably, the top and bottom surfaces of the connector are provided with two sets of placement holes B that are opposite in position and matched in size, so that the nut A and the bolt A can be hidden in the placement holes B.

[0011] Preferably, the top surface of the nut A has a hexagonal hole B, which facilitates the tightening of the nut A.

[0012] Preferably, the outer side of the connector has two sets of placement holes A that are opposite in position and matched in size, which makes it easy to hide the nut B and the bolt B in the placement holes A.

[0013] Preferably, a hexagonal hole A is provided on the outer side of the nut B, which facilitates the locking of the nut B.

[0014] Preferably, the mounting hole B is positioned diagonally, which ensures the connectivity and firmness of the two sets of connectors, and also saves on the number of limiting threaded anchor rods, thus saving materials.

[0015] 1. This precision sheet metal connection reinforcement structure, through the setting of connectors and limiting threaded anchor rods, installs two sets of connectors at the sheet metal connection. The two sets of limiting threaded anchor rods can improve the stability and strength of the connection between the two sets of connectors, reinforce the connection of the sheet metal, improve the strength of the connection, and prevent breakage.

[0016] 2. By using through holes and limiting screws, the two sets of connectors are secured at the connection point. First, the limiting screw is inserted into the mounting hole A and the through hole, then the limiting threaded anchor is inserted into the mounting hole B, and finally, nuts A and B are used to lock them in place. This allows the sheet metal and connectors to be connected and fixed first, and then the two sets of connectors to be connected and fixed, resulting in high connection stability.
