Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] Terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and clarity, and are not used to limit the scope of implementation of the present utility model. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of implementation of the present utility model.

[0025] Refer to Figures 1-4 , in order to achieve the above object, the present utility model adopts the following technical solution: a multi-layer rack for PCBA circuit boards, including a bottom plate 1, two rectangular enclosing plates are fixedly installed on the upper end surface of the bottom plate 1, and a rotating plate 2 is rotatably connected to both sides of each rectangular enclosing plate. A fixed platform 5 is fixedly installed on the upper end surface of the bottom plate 1, and multiple groups of equally spaced racks 8 are symmetrically fixedly installed on both sides of the fixed platform 5. The cross section of the rack 8 is L-shaped, and multiple equally spaced partition plates 9 are fixedly installed on the upper plane of the rack 8;

[0026] Groove plates 13 are fixedly installed at both end faces of multiple racks 8 on the same side of the fixed platform 5. Multiple parallel inclined sliding grooves 14 are opened on the surface of each groove plate 13, and the same horizontal top rod 15 is slidably connected in two inclined sliding grooves 14 at the same height.

[0027] A plurality of rotating rods 6 are rotatably connected between the two rectangular enclosing plates. A plurality of push plates 7 are fixedly installed on the circular surface of each rotating rod 6. Rocking rods 10 are fixedly installed on the circular surfaces of the same ends of the plurality of rotating rods 6 on the same side of the fixed table 5. The ends of each rocking rod 10 are rotatably connected to a total control bar 11. Through a control board 11, the rotating rods 6 on one side can be controlled.

[0028] The distance between every two partition plates 9 is equal to half of the distance between every two push plates 7. At the same time, in the vertical direction, the recess between every two partition plates 9 faces the push plate 7. The arrangement of the circuit boards in the placement rack 8 is relatively dense, so it is not very easy to take. The purpose of this setting is to enable the push plate 7 to push out every other circuit board.

[0029] A gear 17 is rotatably connected to the upper plane of the fixed table 5. The gear 17 is simultaneously meshed with an active rack and a passive rack. A slider 18 is fixedly connected to the plane of the active rack. The slider 18 is slidably connected to the upper end surface of the fixed table 5. A pull plate 19 is rotatably connected to the upper end surface of the slider 18. The other end of the pull plate 19 is rotatably connected to the side of the rotating plate 2 close to the fixed table 5.

[0030] A clamping block 12 is fixedly installed on the plane of the passive rack. The clamping block 12 is simultaneously slidably connected to the upper end surface of the fixed table 5. The inside of the clamping block 12 is simultaneously slidably connected to the lower half section of the total control bar 11.

[0031] A pull rod 3 is fixedly installed on the outer surface of each rotating plate 2. The shape of the pull rod 3 is set as a T shape.

[0032] Four through openings 16 are formed in the upper end surface of the fixed table 5. Each through opening 16 is respectively arranged directly below the total control bar 11.

[0033] Four moving wheels are rotatably connected to the lower end surface of the bottom plate 1. Each moving wheel is respectively adjacent to the four corners of the lower end surface of the bottom plate 1.

[0034] In the present utility model, when in use, the rotating plate 2 is rotated outwards through the pull rod 3. While the rotating plate 2 rotates outwards, it drives the vertical top rod 4 away from the horizontal top rod 15. Then, the horizontal top rod 15 slides down along the inclined chute 14 under the action of gravity. At this time, the circuit board placed on the placement rack 8 is released from the restriction. At the same time as this process occurs, the rotating plate 2 pulls the slider 18 outwards through the pull plate 19. The slider 18 pulls the driving rack, and through the meshing action of the driving rack and the gear 17, the driven rack drives the clamping block 12 to move. The clamping block 12 drives the total control bar 11 to move towards the fixed table 5. At the same time, in the vertical direction, there is no restriction on the total control bar 11. Thus, the total control bar 11 drives a plurality of rotating rods 6 to rotate. The rotating rods 6 drive the push plate 7 to rotate, and the push plate 7 thus pushes out the circuit board inside the placement rack 8.

[0035] After the circuit board is taken out, the rotating plate 2 is pushed back to its original position. During this process, the rotating plate 2 drives the vertical top rod 4 to move and pushes a plurality of horizontal top rods 15, so that the horizontal top rods 15 push the protruding circuit board back. At the same time as this process occurs, the rotating plate 2 pushes the slider 18 inwards through the pull plate 19. The slider 18 pulls the driving rack, and through the meshing action of the driving rack and the gear 17, the driven rack drives the clamping block 12 to move. The clamping block 12 drives the total control bar 11 to move away from the fixed table 5. At the same time, in the vertical direction, there is no restriction on the total control bar 11. Thus, the total control bar 11 drives a plurality of rotating rods 6 to rotate. The rotating rods 6 drive the push plate 7 to rotate, so that the push plate 7 returns to the vertical state and does not restrict the operation of "the horizontal top rod 15 pushing the protruding circuit board back".

[0036] In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "linkage", "fixation" and the like shall be understood in a broad sense.

[0037] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
