[0013] Beneficial effects

[0014] The utility model provides a turnover vehicle with adjustable built-in space. Compared with the existing technology, it has the following advantages:

[0015] (1) The turnover vehicle with adjustable built-in space drives the adjustment plate to rotate by turning the adjustment hand wheel clockwise. The rotation of the adjustment plate causes the transmission block to slide on the inner surface of the adjustment groove, thereby causing the transmission rods on both sides to slide to the opposite side synchronously. The transmission rods slide inside the transmission plate, thereby causing the transmission spring to be compressed. The sliding of the transmission rod drives the sliding plate and the positioning rod to slide synchronously, causing the positioning rod to slide out of the positioning groove. Subsequently, the height of the upper and lower sets of moving racks is adjusted according to the items to be transported. After the moving rack is adjusted to the specified position, the adjustment hand wheel is released. The transmission spring begins to reset without being affected by external forces, thereby causing the sliding plates and the positioning rods on both sides to slide to the opposite side synchronously. The positioning rods slide to the inside of the positioning groove to achieve snap-on fixation. By providing an adjustment mechanism, the height of the moving rack can be quickly adjusted. By adjusting the height of the moving rack, the size of the built-in space of the vehicle body can be freely adjusted, so that when transporting items of different sizes, the built-in space of the vehicle body can be maximized.

[0016] (2) The turnover vehicle with adjustable built-in space drives the control gear to rotate by starting the fixed motor. The rotation of the control gear drives the linkage tooth plates and linkage plates on both sides to slide synchronously to the opposite sides, so that the linkage plates slide on the surface of the linkage rods. The sliding of the linkage plates drives the slider and the fixed plate to slide synchronously to the opposite sides. The fixed plates clamp and fix fragile objects to keep them stable during transportation. By providing a fixing mechanism and using the fixed motor to drive, the distance between the fixed plates on both sides can be flexibly adjusted. The fixed plates clamp and fix fragile objects and objects that are easy to tip over placed on the top of the fixed frame, thereby keeping the objects stable during transportation and improving the safety of fragile objects and objects that are easy to tip over during transportation.

[0040] When working, first turn the adjusting hand wheel 511 clockwise to drive the adjusting plate 512 to rotate. The rotation of the adjusting plate 512 causes the transmission block 63 to slide on the inner surface of the adjusting groove 513, so that the transmission rods 62 on both sides slide to the opposite side synchronously. The transmission rods 62 slide inside the transmission plate 61, thereby compressing the transmission spring 64. The sliding of the transmission rod 62 drives the sliding plate 514 and the positioning rod 515 to slide synchronously, so that the positioning rod 515 slides out of the positioning groove 522.

The sliding plates 514 and the positioning rods 515 on both sides slide synchronously to opposite sides, and the positioning rods 515 slide to the inside of the positioning grooves 522 to achieve clamping and fixing, so as to maintain the height of the mobile rack 4. Subsequently, fragile objects are placed on the fixed rack 2, and then the fixed motor 31 is started to drive the control gear 32 to rotate. The rotation of the control gear 32 drives the linkage tooth plates 333 and the linkage plates 332 on both sides to slide synchronously to the opposite sides, so that the linkage plates 332 slide on the surface of the linkage rods 331. The sliding of the linkage plates 332 drives the slider and the fixed plate 34 to slide synchronously to the opposite sides, and the fragile objects are clamped and fixed by the fixed plate 34 to keep the fragile objects stable during the transportation process.
