DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0021] Reference Figure 1 and Figure 2 A PCB board turnover material box includes a combined material frame 1 and a movable frame 2. The combined material frame 1 is provided with a plurality of storage support strips 11 evenly arranged in the vertical direction on opposite sides thereof. The combined material frame 1 includes a top plate 12 and a bottom plate 13 symmetrically arranged up and down and two groups of support plate groups located between the top plate 12 and the bottom plate 13. The two groups of support plate groups are respectively located on opposite sides of the top plate 12 and the bottom plate 13 and are fixedly connected to the top plate 12 and the bottom plate 13. The two groups of support plate groups each include three support plates 14 arranged at intervals along the width direction of the top plate 12 and the bottom plate 13. The storage support strips 11 on each side are arranged on the three support plates 14. To support, the number of movable frames 2 is two, which are respectively arranged on the outer sides of the two groups of support plate groups, and the two movable frames 2 are each provided with a plurality of downward pressing clamping strips 21 evenly arranged in the vertical direction, the number of the downward pressing clamping strips 21 is consistent with the number of the storage support strips 11 and each downward pressing clamping strip 21 is located above a corresponding storage support strip 11, and two lifting and adjusting components 15 are provided on the top plate 12, and each lifting and adjusting component 15 is correspondingly connected to a movable frame 2 for adjusting the upper and lower positions of the movable frame 2 so that the downward pressing clamping strip 21 will be pressed toward the storage support strip 11 or the distance between the downward pressing clamping strip 21 and the storage support strip 11 will be enlarged. When in use, the PCB board is inserted into the storage support strips 11 aligned on both sides of the combined material frame 1, and the movable frame 2 is adjusted to descend by the lifting and adjusting component 15, so that the downward pressing clamping strip 21 descends to press the PCB board tightly against the storage support strip 11 to fix the PCB board, so that the PCB board is not easy to shake or fall during transportation, thereby avoiding damage to the PCB board. The movable frame 2 is adjusted to rise by the lifting and adjusting component 15 to increase the distance between the downward pressing clamping strip 21 and the storage support strip 11 to facilitate the removal of the PCB board.
[0022] Reference Figure 2 , Figure 3 and Figure 4The movable frame 2 includes a middle plate 22, side plates 23 arranged on opposite sides of the middle plate 22, and two fixed plates 24 respectively arranged on the sides of the two side plates 23. The two fixed plates 24 are parallel to the middle plate 22. The middle plate 22, the two side plates 23 and the two fixed plates 24 are integrally formed. During installation, the middle plate 22 corresponds to the middle support plate 14 on the combined material frame 1. A groove is formed between the two side plates 23 to accommodate the middle support plate 14 on the combined material frame 1 to avoid the support plate 14. The two side plates 23 and the fixed plates 24 thereon are respectively inserted from the two gaps of the support plate group. The downward pressing clamping strip 21 is arranged on the two fixed plates 24, so that each downward pressing clamping strip 21 and a storage support strip 11 are installed in an upper and lower alignment manner.
[0023] Reference Figure 1 The cross section of the storage support bar 11 is L-shaped, which is convenient for installing and fixing the storage support bar and supporting the PCB board.
[0024] Reference Figure 5 A protrusion 211 is protruded at the bottom of the downward pressing card strip 21, and the protrusion 211 matches the card slot formed at the edge of the PCB board, and the height of the protrusion 211 matches the thickness of the PCB board. When the downward pressing card strip 21 is pressed down, the protrusion 211 is inserted into the card slot, and the bottom surface of the downward pressing card strip 21 presses against the PCB board, thereby pressing and limiting the PCB board, and the PCB board is less likely to shake or fall.
[0025] Reference Figure 6 The top plate 12 is provided with a carrying hole 121, and two carrying holes 121 are arranged at intervals. The top plate 12 forms a handle between the two carrying holes 121, and the handle is convenient for lifting the material box for transportation.
[0026] Reference Figure 1 The lifting and adjusting assembly 15 includes a screw 151 and a connecting piece 152. The screw 151 is rotatably connected to the top plate 12. The screw 151 is threadedly connected to the connecting piece 152. The connecting piece 152 is fixedly connected to the middle plate 22. The lifting and adjusting of the movable frame 2 can be achieved by twisting the screw 151 forward or backward to make the movable frame 2 rise or fall.
[0027] Reference Figure 1 and Figure 2 The middle support plate 14 of the two support plate groups is provided with a slide rail 16 and a slider 17 slidably connected to the slide rail 16 on a side away from the storage support bar 11. The middle plate 22 is fixedly connected to the slider 17. The slide rail 16 guides the movement of the movable frame 2 to make the movement of the movable frame 2 more stable.
[0028] Reference Figure 1 and Figure 2Tension springs 18 are provided on opposite sides of the bottom plate 13, and each intermediate plate 22 is connected to the tension spring 18 on the same side thereof, so that when the lifting adjustment assembly 15 adjusts the movable frame 2, the load is balanced by the tension spring 18 to facilitate the control of the lifting stroke of the movable frame 2.
