Board-to-board quick positioning device and its matching components

The present invention provides a board-to-board quick positioning device and a matching component thereof, in particular, a push rod that can be pressed into a butt sleeve, and the elastic positioning member that is sleeved on the fixing seat is used to resist the displacement of the floating body. The second plate body and the first plate body are locked or disengaged on the clamping portion of the push rod, thereby achieving the advantages of simple operation, firm assembly and accurate positioning.

When the general panel (board-to-board) is combined, it is locked by a positioning screw equipped with a knob, a collar and a screw, and the screw and the collar are fixed on the first panel, and the knob is rotated. The screw is locked in the second panel to form a preset position, and then the hand tool is used to lock the screw, so that the first panel and the second panel are locked and fixed into one body, and can be used in a telecom cabinet, an industrial computer, and a work. The mother machine or the like uses a device composed of a plurality of devices and a mechanism to perform a board-to-board connection.

Furthermore, please refer to the ninth figure, as can be clearly seen from the figure, wherein the cap A is embedded with a screw A1 having a nut A11, and the elastic body B is sleeved on the screw A1. The cap A and the elastic body B are assembled on the joint C, and the inner hook A2 at the lower side of the cap A is engaged with the flange C1 at the top end of the joint C, thereby the cap A and the elastic body B can be And the connecting seat C is formed into a positioning device D, and then the locking device C2 of the positioning device D at the bottom end of the connecting base C is embedded and fixed in the positioning plate body E, and then the cap A can be used by using a hand tool. The screw A1 is locked in the fixed plate body E1, thereby achieving the purpose of locking the fixed plate body E and the fixed plate body E1, and after the user removes the fixed plate body E1, the positioning device D can still utilize the link. The seat C is fixed in the positioning plate body E without being lost.

However, in the case of the increasing popularity of equipment such as cabinets, industrial computers, and work machines, the use of the screw A1 to lock the positioning plate E and the fixed plate E1 is easy to be operated and used. The limitation allows the user to spend more time and manpower on the disassembly and assembly work, which is not convenient for quick disassembly and assembly, and the screw A1 in the cap A also needs to be locked into the fixed plate body E1 by using a hand tool. If the user neglects to carry the adapted hand tools, it will seriously affect the overall disassembly and assembly work. Not only is it time-consuming and inconvenient, but also the cost of working hours will increase, and those who have yet to work in this industry will redesign them. Effectively solved.

Therefore, the inventors have drawn up the relevant problems and defects in the use of the positioning device, and collected relevant data through multi-party evaluation and consideration, and used the years of experience in the industry to continuously design and modify the board-to-board.
