Description

[Technical field]

[0001] The invention relates to the field of circuit boards, and in particular to a telescopic plug-in board rack. [Background technology]

[0002] The names of circuit boards include: ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, PCBs, ultra-thin circuit boards, ultra-thin circuit boards, printed (copper etching technology) circuit boards, etc. Circuit boards miniaturize and visualize circuits, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layouts.

[0003] During the manufacturing process of circuit boards, a plug-in board frame is required to load the circuit boards. The plug-in board frame is provided with a plurality of plug-in board slots, so that the circuit boards can be inserted into the plug-in board frame along the plug-in board slots, thereby separating the plurality of circuit boards. For example, patent application number: CN201220382892.2 discloses a circuit board plug-in board rack, a rectangular frame, a slot board for inserting circuit boards, the slot board includes a first slot board and a second slot board, and a bottom plate for supporting the circuit board, the first slot board and the second slot board are parallel, and the slot board is provided with a slot for inserting the circuit board, when the circuit board is fixed, the position of the second slot board is adjusted and the two ends of the circuit board are respectively inserted between the second slot board and the first slot board, but this type of plug-in board rack can only fix one size of circuit board at a time, and when two circuit boards need to be fixed at the same time, two correspondingly adapted plug-in board racks are required to hold them, which will lead to tight turnover of the plug-in board rack, seriously affecting production capacity and work efficiency.

[0004] The present invention is proposed in view of the deficiencies in the prior art. [Summary of the invention]

[0005] The purpose of the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a telescopic plug-in board rack.

[0006] The present invention can be implemented by the following technical solutions:

[0007] The present invention discloses a telescopic plug-in plate rack, comprising a symmetrically arranged left frame and a right frame, wherein support tubes are symmetrically fixed on both sides of the left frame, support rods are fixed on positions corresponding to the support tubes on the right frame, ends of the support rods are arranged in the support tubes at corresponding positions and are slidably connected to the support tubes, a limiting block is also fixed on the support tube, a bolt threadedly connected to the limiting block is arranged on the limiting block, a partition is also arranged between the left frame and the right frame, limiting tubes are fixed on both ends of the partition, the support tube passes through the limiting tube and is slidably connected to the limiting tube, a screw threadedly connected to the limiting tube is also arranged on the limiting tube, positioning slots are fixed on the left frame and the right frame, and limiting slots are fixed on both sides of the partition. Adjust the position of the partition according to the size of the circuit board to be fixed, so that the distance between the partition and the left frame is adapted to the size of the circuit board. After adjusting the distance of the partition, turn the screw. Since the screw is threadedly connected to the limit tube, when the screw is rotated, the screw moves close to the support tube, and the bottom of the screw is squeezed with the support tube, and then the limit tube is fixed to the support tube. After the partition is fixed, adjust the position of the right frame according to the size of another circuit board. After adjusting the right frame to a suitable position, turn the bolt. Since the bolt is threadedly connected to the limit block, when the bolt is rotated, the bolt moves close to the support rod, and the bottom of the bolt passes through the limit block and the support tube and is squeezed with the support rod. The right frame is fixed. After the right frame is fixed, the distance between the right frame and the partition is adapted to the size of another circuit board. After the right frame is fixed, one circuit board is inserted between the left frame and the partition, and the bottom of the circuit board is inserted between the positioning card slot and the limit card slot, and separated by the positioning card slot and the limit card slot, and another circuit board is inserted between the right frame and the partition, and the circuit boards are separated and fixed by the positioning card slot and the limit card slot. This device can meet the fixing needs of two circuit boards of different sizes by adjusting the position of the partition and the position of the right frame, which greatly improves the turnover efficiency of the circuit boards and improves the production capacity and production efficiency of the circuit boards.

[0008] Preferably, the support rod is evenly fixed with a limiting ring. After the bottom of the bolt is inserted between the two limiting rings, it is squeezed with the support rod, which can effectively prevent the support rod and the support tube from sliding relative to each other after the circuit board is fixed.

[0009] Preferably, a plurality of separation tubes are fixed on the left frame and the right frame, and separation tubes are also fixed on the partition plate at positions corresponding to the separation tubes, and the upper ends of the separation tubes are conical. When the circuit boards are inserted into the board rack, the separation tubes separate the adjacent circuit boards to avoid collisions between the circuit boards during transportation.

[0010] Preferably, handles are fixed on the left frame and the right frame, so that the plug-in board rack can be carried more conveniently through the handles.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] This device can meet the fixing requirements of two circuit boards of different sizes by adjusting the position of the partition and the position of the right frame, greatly improving the turnover efficiency of the circuit boards and improving the production capacity and production efficiency of the circuit boards.

After adjusting the distance of the partition 12, rotate the screw 14. Since the screw 14 is threadedly connected to the limiting tube 13, when the screw 14 is rotated, the screw 14 moves close to the support tube 7, and the limiting tube 13 is fixed to the support tube 7 after the bottom of the screw 14 is squeezed with the support tube 7. After the partition 12 is fixed, adjust the position of the right frame 2 according to the size of another circuit board 17.
