The invention discloses a circuit board installing and clamping device, and belongs to the technical field of circuit boards. The circuit board installing and clamping device solves the technical problems that a circuit board installing and clamping mode in the prior art is inconvenient to use, large in occupied space and not suitable for occasions with seriously-limited space. The circuit board installing and clamping device comprises a base board, a left stand board, a right stand board, a top board, a floating pressing board and elastic mechanisms, wherein the base board is provided with first board clamping grooves, the lower end of the left stand board and the lower end of the right stand plate are both fixedly connected with the base board, the top board is provided with floating pressing board guide grooves and fixedly connected with the upper end of the left stand board and the upper end of the right stand board, the floating pressing plate is arranged in the floating pressing board guide grooves and connected with the top board through adjustment mechanisms, the elastic mechanisms are arranged between the floating pressing plate and the top board, the floating pressing board is provided with second board clamping grooves, the first board clamping grooves and the second board clamping grooves are symmetrically arranged to be used for containing the circuit boards, and the adjustment mechanisms are used for adjusting the pre-tightening force of the elastic mechanisms and controlling the floating pressing board to ascend and descend. The circuit board installing and clamping device is reliable in fixing, convenient to assemble and disassemble, small in space size and free of influences on the fixing effects on the circuit boards.
Description
technical field [0001] The invention relates to a circuit board clamping device, which belongs to the technical field of circuit boards. Background technique [0002] In the prior art, there are mainly two methods for mounting the circuit board. One is to directly fix with screws. Although this fixing method is simple, reliable, economical and practical, it needs to open corresponding mounting holes on the circuit board, and when the circuit board When the board needs to be plugged and pulled out before use or during use, all mounting screws must be removed, which is very inconvenient to operate; another method is to use guide grooves and pullers to fix and plug in and out. The advantages of this installation method are The card installation is reliable and easy to plug and unplug, but the structure is relatively complicated. Not only does it need to drill mounting holes on the circuit board, but it also occupies a large volume in the direction of plugging and unplugging the...
