Description

Technical Field

[0001] This utility model relates to the field of logistics and transportation, specifically to a transportation device adapted to the placement of different logistics packaging boxes. Background Technology

[0002] Packaging box transport devices are lightweight and flexible logistics handling equipment, typically featuring a metal frame with casters. The load-bearing panel can hold various packaging boxes or goods. Features include: lightweight body (usually made of steel / aluminum alloy), four-wheel braking system, foldable handle or adjustable height structure. Some models are equipped with anti-slip rubber pads or strap fixing devices. They are suitable for short-distance transportation in warehouses, workshops, express delivery and other scenarios, effectively reducing the intensity of manual handling and improving turnover efficiency. Some high-end models also integrate electronic scale or barcode scanner functions.

[0003] Existing packaging box transportation devices sometimes use a four-corner positioning mechanism to fix the packaging box, achieving box positioning by simultaneously contracting the four clamping points. However, this design can only adapt to packaging boxes within a specific size range. When the length and width ratio of the packaging box varies greatly, diagonal clamping may fail or uneven force may occur, causing the box to shake or even fall off during transportation. This lack of flexibility in meeting diverse logistics packaging needs restricts the scope of use and work efficiency of the equipment.

[0004] In summary, to improve the versatility and operational efficiency of packaging box transportation devices, it is necessary to address the issue of poor adaptability of the four-corner synchronous positioning mechanism to packaging box dimensions. This would enable the device to flexibly meet the clamping requirements of packaging boxes with different length-to-width ratios, thereby preventing box shaking or detachment during transportation and significantly expanding the application range of the equipment in diverse logistics scenarios. Utility Model Content

[0005] The purpose of this utility model is to provide a transportation device that can adapt to the placement of different logistics packaging boxes. By adding clamping components that can move according to the size of the packaging box to the four corner positioning structure of the transport vehicle, it can flexibly meet the clamping needs of packaging boxes with different length and width ratios, and solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a transport device adaptable to the placement of different logistics packaging boxes, including a mobile cart. Four sliding rods are slidably connected to the mobile cart, each of the four sliding rods having a groove. A slider is slidably connected inside the groove, and a rubber column is installed on the slider. A rack is fixed to the side of the slider, and the rack is slidably connected to the groove.

[0022] The present invention will be further described below with reference to specific embodiments.

[0023] Refer to the instruction manual appendix Figures 1 to 5A transport device adaptable to the placement of different logistics packaging boxes includes a mobile cart 1. Four sliding rods 2 are slidably connected to the mobile cart 1. Each of the four sliding rods 2 has a sliding groove 3. A slider 4 is slidably connected inside the sliding groove 3. A rubber column 5 is installed on the slider 4. A rack 6 is fixed to the side of the slider 4. The rack 6 is slidably connected to the sliding groove 3. Two positioning seats 7 are installed at the bottom of the sliding rods 2. A transmission gear 8 is rotatably connected between the positioning seats 7. A ratchet 9 is provided on one side of the positioning seat 7. The ratchet 9 is fixed to the transmission gear 8 through a connecting shaft. A lifting assembly is provided on the sliding rod 2. The lifting assembly is provided with ratchet teeth 11. An adjustment mechanism for moving the sliding rods 2 is provided inside the mobile cart 1. A positioning assembly is provided on the mobile cart 1. A support assembly is provided on the side of the mobile cart 1.

[0024] It should be noted that when the adjusting mechanism drives the four sliding rods 2 to retract synchronously, the rubber column 5 will contact the logistics packaging box. After the rubber column 5 contacts the logistics packaging box, the sliding rod 2 continues to move, while the slider 4 will remain relatively stationary under the restriction of the rubber column 5. At this time, the rack 6 will passively slide inside the slide groove 3. The transmission gear 8 meshes with the rack 6 and is driven to rotate by the rack 6. The transmission gear 8 drives the ratchet 9 to rotate synchronously. The ratchet 11 will engage with the tooth groove of the ratchet 9 in sequence, thereby preventing the ratchet 9 and the gear from rotating back. This is to prevent the rubber column 5 from moving back and causing the positioning to become loose. When it is necessary to release the positioning, the ratchet 11 can be moved upward by the lifting component to release the engagement.

[0025] Refer to the instruction manual appendix Figure 1 and Figure 4 The adjustment mechanism includes a rotating component installed inside the mobile vehicle 1, a linkage component fixed inside the mobile vehicle 1, and a drive component installed on the side of the mobile vehicle 1. The drive component drives the rotating component to rotate through the linkage component.

[0026] It should be noted that the power is input through the drive component, transmitted to the rotating component through the linkage component, and finally synchronously controls the four slide bars 2 to move radially along the moving vehicle 1, thereby achieving adaptive adjustment of the clamping range.

[0027] Refer to the instruction manual appendix Figure 4 The rotating assembly includes a four-corner turntable 121 rotatably connected inside the mobile vehicle 1, a slot 122 opened on the four-corner turntable 121, and a guide post 123 fixed on the slide bar 2. The guide post 123 is adapted to the slot 122.

[0028] It should be noted that when the four corner turntables 121 rotate, their slots 122 move the guide posts 123, forcing the four slide rods 2 to move towards or away from the center of the moving vehicle 1 with exactly the same stroke, thus ensuring the symmetry of the clamping and positioning.

[0029] Refer to the instruction manual appendix Figure 4The linkage component includes a support 124 fixed inside the mobile vehicle 1, a rotating shaft 125 rotatably connected to the support 124, a first bevel gear 126 fixed to the end of the rotating shaft 125, and a second bevel gear 127 fixed to the bottom of the four corner turntables 121. The first bevel gear 126 meshes with the second bevel gear 127.

[0030] It should be noted that the vertical rotational motion of the drive component is converted into the horizontal rotational motion required by the rotating component through the vertical meshing transmission of the first bevel gear 126 and the second bevel gear 127.

[0031] Refer to the instruction manual appendix Figure 1 and Figure 4 The drive assembly includes a bushing 128 fixed to the side of the mobile vehicle 1 and a handle 129 rotatably connected to the bushing 128. The handle 129 is fixedly connected to the rotating shaft 125.

[0032] It should be noted that the operating power is provided by rotating the handle 129, which directly drives the linkage component to operate via the rotating shaft 125, providing a manual input source for the entire adjustment mechanism.

[0033] Refer to the instruction manual appendix Figure 2 and Figure 3 The lifting assembly includes a lead screw 101 threaded onto the slide bar 2 and a knob 102 fixed onto the lead screw 101. The lead screw 101 is rotatably connected to a corresponding ratchet 11, and the ratchet 11 is slidably connected to the slide bar 2.

[0034] It should be noted that by rotating the lead screw 101, the ratchet 11 is driven to move vertically up and down along the slide bar 2, thereby engaging or disengaging the ratchet 11 into or out of the tooth groove of the ratchet 9.

[0035] Refer to the instruction manual appendix Figure 1 The positioning component includes multiple fixing plates 131 fixed on the mobile vehicle 1, fixing screws 132 threaded to the four corners of the fixing plates 131, and a bracket 133 fixed on the fixing plates 131. The bracket 133 is used to connect the elastic strap.

[0036] It should be noted that the elastic straps connected to the card holder 133 are used to assist in securing and fixing high or easily tipped packaging boxes, thereby enhancing transportation stability.

[0037] Refer to the instruction manual appendix Figure 1 and Figure 5 The support assembly includes multiple mounting plates 141 fixed to the side of the mobile vehicle 1, screws 142 threaded to the mounting plates 141, and a washer 143 disposed at the bottom of the screws 142, the washer 143 being rotatably connected to the screws 142.

[0038] It should be noted that by adjusting the height of the shim 143 by turning the screw 142, adjustable horizontal support is provided for the mobile vehicle 1 to prevent the vehicle body from shaking when loading and unloading goods.

[0039] Working principle: The operator turns the handle 129, which drives the first bevel gear 126 to rotate via the fixed shaft 125. The first bevel gear 126 meshes with the second bevel gear 127 fixed at the bottom of the four corner turntables 121, driving the four corner turntables 121 to rotate horizontally. The slots 122 on the four corner turntables 121 actuate the guide posts 123 fixed on the slide rods 2, causing the four slide rods 2 to retract and move synchronously towards the center of the moving vehicle 1. When the slide rods 2 move, the sliders 4 on them contact the side of the packaging box through the rubber posts 5. When the rubber posts 5 abut against the box body, As the slide bar 2 continues to move, the rubber column 5 forces the slider 4 to remain relatively stationary within the groove 3. At this time, the rack 6 on the side of the slider 4 slides within the groove 3, causing the transmission gear 8 meshing with it to rotate. The transmission gear 8 drives the ratchet 9 to rotate via the connecting shaft. The ratchet 11 on the slide bar 2 then engages in the tooth groove of the ratchet 9, effectively preventing the ratchet 9 and the transmission gear 8 from rotating back, thereby avoiding the rubber column 5 from shifting back and causing the positioning to loosen. When it is necessary to release the positioning, rotate the knob 102 to drive the lead screw 101 to rotate, and lift the ratchet 11 upward to disengage it from the tooth groove of the ratchet 9.
