Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a circuit board storage box. Background Art

[0002] After production and quality inspection, circuit boards need to be stored in a moisture-proof environment and wait for bulk packaging and shipment. Existing storage equipment is mostly rough placement racks and carton sealing. On the one hand, it is not conducive to the moisture-proof and humidity-proof storage of circuit boards. On the other hand, the carton size cannot effectively match circuit boards of different specifications, resulting in the inability to fully utilize the carton space. Therefore, it is necessary to provide a new circuit board storage box to solve the above technical problems. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a circuit board storage box. The utility model has a simple structure and can be adjusted and stored according to the size of the circuit board. At the same time, the circuit board is not damaged by friction during the entire storage and retrieval process and the operation is convenient.

[0004] The circuit board storage box provided by the utility model comprises a box body with a sealing door, a box frame is further provided in the box body, two vertically arranged support plates are horizontally slidably provided in the box frame, a group of support channel steels are provided at the same height on the opposite side walls of the two support plates and the box frame, an L-shaped placement plate is slidably inserted in the support channel steel, a limiting hole is provided at one end of the support channel steel facing the sealing door, the placement plates corresponding to the same group of support channel steels are bent oppositely towards one end of the sealing door and fixed with mounting plates, and a limiting rod for matching the limiting hole is slidably inserted on the mounting plate. When placing the circuit board, the placement plate can be moved out from the inside of the support channel steel, and the staff can quickly stack the circuit boards in sequence between the two placement plates, and then slide the placement plate filled with circuit boards along the support channel steel to enter the box frame to complete the storage of the circuit board, and the entire circuit board is not damaged by friction.

[0005] Preferably, the limiting rod is provided with a support sheet, the support sheet is connected to the mounting sheet via a second spring, and a gripping rod is vertically fixed to the end of the limiting rod away from the limiting hole. When the placement plate needs to be pulled out, it is only necessary to pinch the two limiting rods at the same time and move them in opposite directions, so as to overcome the elastic force of the second spring and separate the limiting rod from the limiting hole, and then the placement plate can be pulled out. After the circuit board is placed, the second spring can drive the limiting rod to move toward the supporting channel steel through its own elastic force, and as the placement plate continues to slide into the box frame, when the limiting rod moves to the limiting hole, it can be inserted into the limiting hole, thereby limiting the placement plate.

[0006] Preferably, a top plate is slidably provided at one end of the placement plate away from the limiting hole, a baffle is provided at one end of the support channel steel away from the sealing door, and a first spring is provided between the top plate and the baffle. In the process of placing the circuit board and pushing the placement plate into the box frame, the first spring continuously applies a force to the top plate toward the sealing door, and enables the top plate to effectively resist the circuit board on the placement plate, preventing the circuit board from falling from the gap in the placement plate. Similarly, when the placement plate is pulled out, the first spring will continue to squeeze the circuit board until the placement plate moves to the first spring to restore its original state, so that the staff can smoothly take out the circuit board for packing and shipment.

[0007] Preferably, the top and bottom of the box frame are provided with sliding grooves, and the sliding grooves are slidably matched with the protrusions arranged on the two support plates, and the protrusions located on the top of the support plate pass through the box frame and are connected to the bottom of the connecting plate, and the connecting plate is screwed with the rotating rod through a preset screw hole.

[0008] Preferably, two support blocks are fixedly provided on the top of the box frame and the two support blocks are rotatably connected to the two ends of the rotating rod respectively. The two ends of the rotating rod are provided with threaded sections with opposite rotation directions and are respectively threadedly engaged with corresponding connecting pieces.

[0009] By rotating the rotating rod with threaded sections rotating in opposite directions at both ends, the corresponding support plates can be driven to move relative to or away from each other through the connecting piece when the rotating rod is rotated, thereby adjusting the distance between the two support plates and the corresponding side walls of the box frame, and then adjusting the distance between two equal-height support channel steels and the placement plate to adapt to the size specifications of the circuit boards to be accommodated.

[0010] Compared with the related art, the circuit board storage box provided by the utility model has a simple structure and can be adjusted and stored according to the size of the circuit boards. At the same time, the circuit boards are not damaged by friction during the entire storage and retrieval process and the operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0016] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0017] See also Figures 1 to 4 , a circuit board storage box, comprising a box body 1 with a sealing door, a box frame 2 is also provided in the box body 1, two vertically arranged support plates 3 are horizontally slidably provided in the box frame 2, and a slide groove 23 is opened at the top and bottom of the box frame 2, and the slide groove 23 is slidably matched with the protrusions 31 arranged on the two support plates 3, and the protrusion 31 located at the top of the support plate 3 passes through the box frame 2 and is connected to the bottom of the connecting piece 32, and the connecting piece 32 is screwed with a rotating rod 33 through a preset screw hole; two support blocks 34 are fixedly provided on the top of the box frame 2 and the two support blocks 34 are rotatably connected to the two ends of the rotating rod 33 respectively, and the two ends of the rotating rod 33 are provided with threaded sections with opposite rotation directions and are respectively screwed with the corresponding connecting pieces 32.

[0018] An array of support channel steels 4 are provided at the same height on the opposite side walls of the two support plates 3 and the box frame 2, an L-shaped placement plate 51 is slidably inserted into the support channel steel 4, a limiting hole 41 is provided at one end of the support channel steel 4 facing the sealing door, a top plate 52 is slidably provided at the end of the placement plate 51 away from the limiting hole 41, a baffle plate 522 is provided at the end of the support channel steel 4 away from the sealing door, and a first spring 521 is provided between the top plate 52 and the baffle plate 522.

[0019] The placement plate 51 corresponding to the same group of supporting channel steels is bent toward one end of the closing door and fixed with a mounting plate 53, on which a limiting rod 531 for cooperating with the limiting hole 41 is slidably inserted, and a supporting plate 532 is provided on the limiting rod 531, and the supporting plate 532 is connected to the mounting plate 53 by a second spring 533, and a gripping rod 54 is vertically fixed to the end of the limiting rod 531 away from the limiting hole 41.

[0020] First, adjust the storage space according to the size of the current batch of circuit boards:

[0021] By rotating the rotating rod 33, the two connecting pieces 32 can drive the corresponding support plates 3 to move relative to or away from each other through the threaded sections at both ends of the rotating rod 33 rotating in opposite directions, and then the distance between the two support plates 3 and the corresponding side walls of the box frame 2 can be adjusted, thereby adjusting the distance between the two equal-height support channel steels 4 and the placement plate 5 to adapt to the size specifications of the circuit boards to be accommodated.

[0022] Next, place the circuit board:

[0023] By pinching the limiting rods 531 of the two equal-height placement plates 5 at the same time and moving them toward each other, the elastic force of the second spring 533 can be overcome to separate the limiting rods 531 from the limiting holes 41, and then the placement plates 51 can be moved out from the inside of the supporting channel steel 4. The staff can quickly stack the circuit boards between the two placement plates 51 in sequence, and then slide the placement plates 51 filled with circuit boards along the supporting channel steel 4 to enter the box frame 2 to complete the storage of the circuit boards.

[0024] In the above process, the first spring 521 continuously applies a force to the top plate 52 toward the closing door, and enables the top plate 52 to effectively resist the circuit board on the placement plate 51, preventing the circuit board from falling from the gap of the placement plate 51. Similarly, when the placement plate 51 is pulled out, the first spring 521 will continue to squeeze the circuit board until the placement plate 51 moves to the first spring 521 to restore to its original state, so that the staff can smoothly take out the circuit board for packaging and delivery;

[0025] At the same time, the second spring 533 can drive the limiting rod 531 to move toward the supporting channel steel 4 through its own elastic force, and as the placement plate 51 continues to slide into the box frame 2, when the limiting rod 531 moves to the limiting hole 41, it can be inserted into the limiting hole 41, thereby limiting the placement plate 51.

[0026] Finally, close the sealing door to effectively preserve the circuit board.

Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
