[0015] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] Embodiment 1

[0017] Please refer to Figure 1 、 2 A circuit board storage and transportation vehicle includes a frame 1 and a plurality of brackets 2 rotatably connected to the frame 1; the plurality of brackets 2 are stacked from top to bottom; a spring 3 is connected between the frame 1 and the bracket 2;

[0018] The bracket 2 includes telescopic modules 21 symmetrically arranged on both sides of the vehicle frame 1. The telescopic module 21 includes a guide block 211 rotatably connected to the vehicle frame 1 and a movable block 212 slidably connected to the guide block 211. A tray 22 for placing a circuit board is provided between the movable blocks 212 of the two telescopic modules 21. The spring 3 is connected to the guide block 211;

[0019] The movable block 212 is provided with a bayonet 2121, and at least two elastic limit members 2111 are arranged at intervals along the sliding direction of the guide block 211; when the bayonet 2121 is stuck on the elastic limit member 2111, the movable block 212 cannot slide.

[0020] The bracket 2 of this embodiment can be adjusted and maintained at a certain inclination angle for the staff to pick up and place the circuit board. At the same time, by telescoping the bracket 2 back and forth, the position of the bracket 2 can be changed, so that the bracket 2 can carry special circuit boards, and the larger electronic components on the circuit board can be suspended, avoiding accidental damage to the electronic components on the circuit board during the transfer process by the staff;

[0021] Refer to Figure 2 , in actual application, when the staff retracts the bracket 2 of a certain layer into the interior, the distance between the upper bracket 2 and the lower bracket 2 of the bracket 2 can be increased. The larger electronic components on the circuit board can be located between the upper bracket 2 and the lower bracket 2 of the bracket 2, avoiding the larger electronic components on the circuit board being directly supported on the tray 22. In this way, the circuit board does not need to be tilted, and the electronic components are not easily loosened during the transfer process.

[0022] In actual application, when the movable block 212 slides to a certain position, the elastic limit member 2111 on the guide block 211 will pop up and be clamped on the bayonet 2121, thereby restricting the movable block 212 from continuing to slide. This design can keep the movable block 212 stably supporting the circuit board;

[0023] As for the structure of the elastic limit member 2111, the positioning elastic piece of an umbrella can be referred to, such as a V-shaped elastic piece, which will not be elaborated in this embodiment. It should be noted that, for the convenience of the staff to adjust its telescoping, in actual application, the elastic limit member 2111 can be provided only on one side of the guide block 211. In addition, the action mode of the spring 3 is briefly described in this embodiment. When the bracket 2 is laid flat, the spring 3 is in a straightened (loaded) state and provides a supporting force so that the bracket 2 can maintain an angle; when the bracket 2 is lifted, since the bracket 2 is lifted manually, the stroke of the spring 3 does not decrease, so the spring 3 is still in a straightened (loaded) state, only the force direction of the spring 3 has changed. Therefore, when the bracket 2 is lifted, the spring 3 is still in a straightened (loaded) state, and the bracket 2 will not fall due to gravity.

[0024] In this embodiment, more preferably, in order to enable the bracket 2 to work stably, a plurality of connecting columns 23 are arranged on the vehicle frame 1 at intervals from bottom to top, and two guide blocks 211 of the telescopic module 21 are rotatably connected to the same connecting column 23 so that the two rotate synchronously.

[0025] In this embodiment, a limiting block 2122 is provided at the bottom of the movable block 212; the limiting block 2122 abuts against the bracket 2 in the lower layer to place the circuit board in parallel.

[0026] In this embodiment, specifically, the vehicle frame 1 includes a base 11 and two columns 12 symmetrically arranged on both sides; the columns 12 are arranged on the base 11 and are provided with 13 mounting positions from top to bottom; 13 brackets 2 are sequentially rotatably connected to the mounting positions; one end of the spring 3 is arranged on the column 12 through a pin, and the other end of the spring 3 is arranged on the guide block 211.

[0027] In order to facilitate the staff to push and pull the storage and transportation vehicle, as a preference of this embodiment, the vehicle frame 1 further includes a handle 13; both ends of the handle 13 are respectively arranged on the columns 12 on both sides.

[0028] As a further preference of this embodiment, pulleys 14 are provided at the bottom of the base 11.

[0029] In this embodiment, a protective layer 24 made of a flexible material is provided on the upper surface of the pallet 22. Preferably, the protective layer 24 of this embodiment is non-woven fabric and extends to the guide block 211 all the time, so as to prevent the circuit board from accidentally falling from the rear end. It should be noted that when the movable block 212 contracts, the non-woven fabric can be folded up without affecting the normal contraction of the movable block 212.

[0030] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention, and the scope of the present invention is defined by the claims and their equivalents.
