DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 2In this embodiment, a material storage mechanism for road freight transportation includes two connecting frames 1. The top and bottom of the outer surfaces of the two connecting frames 1 are provided with the same connecting plate 2. The inner cavities of the two connecting frames 1 are provided with two load-bearing plates 3. The outer surfaces of the two load-bearing plates 3 are provided with the same adjusting plate 4. An adjusting mechanism 5 for adjusting the positions of the two load-bearing plates 3 is provided at the center between the inner top wall and the inner bottom wall of the adjusting plate 4 on the opposite side. The inner walls on the opposite sides of the two connecting frames 1 are provided with a locking mechanism 6 for adjusting the distance between the upper and lower load-bearing plates 3.

[0023] Among them, the cross-sectional shape of the connecting frame 1 is an inverted U shape, and sliders are fixed on the opposite sides of the two connecting frames 1. The inner top wall and the inner bottom wall of the connecting plate 2 are provided with sliding grooves, and the sliders are slidingly connected to the sliding grooves. Guide holes matching the size of the connecting frame 1 are provided on the left and right sides of the connecting plate 2.

[0024] In addition, a groove is provided on the upper surface of the connecting frame 1, and a protrusion is fixed on the lower surface of the connecting frame 1. The size of the protrusion is adapted to the size of the inner cavity of the groove, which can facilitate the user to stack the storage mechanism.

[0025] See also Figure 3 In order to adjust the length of the two bearing plates 3 extending out of the adjustment plate 4, the adjustment mechanism 5 in this embodiment includes a rotating rod 501 rotatably connected to the center between the inner top wall and the inner bottom wall of the adjustment plate 4 through a bearing, a rotating gear 502 is fixed to the outer surface of the rotating rod 501, and a driving plate 503 is fixed to the side of the bearing plate 3 facing the rotating rod 501. The rotating rod 501 is rotated, and the rotation of the rotating rod 501 causes the rotating gear 502 fixed on its surface to rotate. The rotation of the rotating gear 502 drives the two racks 504 to move in opposite directions, thereby causing the two driving plates 503 to move. They move in opposite directions, and a rack 504 is fixed to the side of the driving plate 503 facing the rotating gear 502. Through holes 505 are provided on the left and right sides of the adjusting plate 4. A card slot 506 is provided on the upper surface of the rotating rod 501, and a card block 507 is inserted into the inner cavity of the card slot 506. The movement of the driving plate 503 causes the two load-bearing plates 3 to move out from the inner cavity of the through hole 505, and drives the distance between the two connecting frames 1 to increase, thereby increasing the storage space. Then the card block 507 is inserted into the inner cavity of the card slot 506, so that the storage space of the material can be adjusted, thereby improving the adjustment efficiency of the user.

[0026] Among them, the lower surface of the rotating rod 501 passes through the load-bearing plate 3 and extends to the lower side of the load-bearing plate 3, the rotating gear 502 is meshed with the rack 504, and the left and right ends of the inner top wall and the inner bottom wall of the load-bearing plate 3 on the opposite side are provided with limit grooves, and the upper and lower ends of the driving plate 503 are fixed with limit blocks, and the limit blocks are slidably connected with the limit grooves. When the two driving plates 503 move, the limit blocks fixed on the upper and lower sides move in the inner cavity of the limit grooves, which can limit the movement of the driving plates 503. The cross-sectional shape of the clamping block 507 is a cross, and a cross hole is provided on the upper surface of the load-bearing plate 3. The clamping block 507 is pulled out from the inner cavity of the clamping slot 506 and the cross hole, so as to release the limit on the rotating rod 501.

[0027] See also Figure 4 In order to adjust the distance between the upper and lower load-bearing plates 3, the engaging mechanism 6 in this embodiment includes a slot 601 provided on the inner wall of the two connecting frames 1 on the opposite side, and the left end of the left load-bearing plate 3 and the right end of the right load-bearing plate 3 are both provided with an empty slot, and a telescopic rod 602 is fixed on the opposite side of the empty slots at the left and right ends, and a spring 603 is movably sleeved on the outer surface of the telescopic rod 602, and a movable plate 604 is fixed on the other side of the telescopic rod 602, and the two ends of the spring 603 are respectively fixedly connected to the side of the movable plate 604 opposite to the empty slot, and the movable plate 604 is moved toward the vertical center axis of the adjusting plate 4. The two movable plates 604 are moved on one side, and the movement of the movable plates 604 shortens the telescopic rod 602, causing the spring 603 to deform. Insert blocks 605 are fixed on the opposite sides of the movable plates 604 at the left and right ends, so that the two insert blocks 605 are moved to the inner cavity of the empty slot, and then the left and right load-bearing plates 3 are moved to a suitable position, and the two movable plates 604 are released. The spring 603 rebounds and drives the telescopic rod 602 to extend, and then pushes the movable plate 604 to move, so that the insert block 605 enters the inner cavity of the slot 601, and the left and right load-bearing plates 3 can be fixed in the inner cavity of the two connecting frames 1.

[0028] Among them, the size of the plug block 605 is compatible with the size of the slot 601, and fixing holes compatible with the size of the plug block 605 are opened on the left and right sides of the load-bearing plate 3. The number of slots 601 is multiple and evenly distributed on the opposite side of the two connecting frames 1.

[0029] It should be noted that the distance between the upper and lower load-bearing plates 3 can be adjusted by the provided engaging mechanism 6, so as to be adaptable to materials of different sizes.

[0030] The working principle of the above embodiment is:

[0031] (1) When adjusting the length of the two load-bearing plates 3 extending out of the adjustment plate 4, first pull the block 507 out of the inner cavity of the slot 506 and the cross hole, so as to release the limit on the rotating rod 501, and then rotate the rotating rod 501. The rotation of the rotating rod 501 causes the rotating gear 502 fixed on its surface to rotate. The rotation of the rotating gear 502 drives the two racks 504 to move in opposite directions, thereby causing the two driving plates 503 to move in opposite directions. When the two driving plates 503 move, the limit blocks fixed on the upper and lower sides thereof move in the inner cavity of the limit slot, which can limit the movement of the driving plates 503. The movement of the driving plates 503 causes the two load-bearing plates 3 to move out of the inner cavity of the through hole 505, and drives the distance between the two connecting frames 1 to increase, thereby increasing the storage space, and then the block 507 is inserted into the inner cavity of the slot 506.

[0032] (2) If the volume of the transported material is large and the distance between the upper and lower load-bearing plates 3 needs to be adjusted, first move the two movable plates 604 to the side close to the vertical center axis of the adjustment plate 4. The movement of the movable plates 604 shortens the telescopic rod 602 and deforms the spring 603, thereby enabling the two plug blocks 605 to move to the inner cavity of the empty slot. Then move the left and right load-bearing plates 3 to appropriate positions, release the two movable plates 604, and the spring 603 rebounds and drives the telescopic rod 602 to extend. Then push the movable plates 604 to move, so that the plug blocks 605 enter the inner cavity of the slot 601, and the left and right load-bearing plates 3 can be fixed in the inner cavity of the two connecting frames 1.
