Four vertical rods are welded on the bottom frame, multiple long rods are arranged between each pair of vertical rods on the same side, multiple placing plates are arranged on each pair of long rods, there is an angle between the length direction of placing plate and horizontal direction, end baffle is formed at one end of placing plate, placing groove is formed in the upper wall of placing plate and the inner wall of end baffle. End baffle plays a limiting role on the inner side end of circuit board, so that the circuit board is limited by the obliquely arranged placing plate. And this way can avoid the circuit board from falling, and this design can reduce the weight of the entire turnover vehicle.

[0006] Further, L-shaped plate is welded on the bottom plate, and the L-shaped plate is installed on the inner side of the bottom frame by screws. The L-shaped plate can strengthen the structural strength of the bottom frame.

[0007] Further, in order to improve the structural strength between the vertical rods, multiple connecting cross rods are arranged between each pair of vertical rods on the same end.

[0008] Further, in order to avoid the wear of the inner wall of the placing groove to the circuit board, the cross section of the placing groove is in V-shaped structure.

[0009] Furthermore, although the above structure basically achieves the goal of preventing the circuit board from falling, the problem of falling still occurs during transfer. To solve this problem, a protrusion is welded to the upper end of the end baffle, and a pair of pull rods are threaded through the protrusion. The lower end of the pull rod is equipped with an end cap, and a spring is fitted onto the lower end of the pull rod. The spring is located between the end cap and the protrusion. An upper plate is provided at the upper end of the pull rod, and a hanging plate is welded to the upper plate. An oblong hole is opened on the hanging plate, and a bayonet is opened at the front end of the hanging plate. A rotating shaft passes through the oblong hole, and rotating side plates are connected to both ends of the rotating shaft. A lower pressure plate is provided at the other end of the rotating side plate. A limit groove is formed in the lower wall of the lower pressure plate, and a locking block is provided between the rotating side plates. The locking block passes through the bayonet so that the length direction of the lower pressure plate is parallel to the length direction of the placement plate. By limiting the upper end of the circuit board through the lower pressure plate, the safety of the circuit board during transfer is improved.

[0010] Furthermore, the limiting groove has a V-shaped cross-section to prevent damage to the circuit board during positioning.

[0011] The advantages of the above technical solution are:

[0012] This invention ensures that the circuit board will not fall during transfer and avoids damage to the circuit board due to shaking or other reasons during transfer. Attached Figure Description
