Description

Technical Field

[0001] This utility model relates to the field of transportation technology, specifically to a handcart that facilitates adjustment of the size of the placement cavity space. Background Technology

[0002] To address issues such as chaotic management of consumables, untimely recycling, and a messy environment at cigarette sorting sites, and to improve the overall efficiency and management level of sorting operations in logistics and distribution centers, it is necessary to use handcarts for placing and transporting cigarette films, cores, and label rolls.

[0003] The existing handcart has multiple placement chambers for storing the roll cores after the roll film has been used up. The roll cores are placed in the placement chambers, but the fixed size of the placement chambers cannot accommodate all types of roll cores. During the movement of the handcart, the roll cores placed in the placement chambers are prone to shaking, which makes the handcart unstable. Excessive shaking of the roll cores can cause the handcart to tilt, which can cause the roll film in the handcart to tilt and fall off. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a handcart that facilitates adjustment of the size of the space between the placement chambers to overcome the problems of the existing technology. Because the existing handcarts have multiple placement chambers for placing the roll cores after the roll film has been used, and the placement chambers are of a fixed size, they cannot accommodate all types of roll cores. During the movement of the handcart, the roll cores placed in the placement chambers are prone to shaking, which makes the handcart unstable. Excessive shaking of the roll cores can cause the handcart to tilt, resulting in the roll film in the handcart tilting and falling off.

[0005] This utility model is implemented by the following technical solution:

[0006] A handcart with adjustable placement cavity spacing includes a handcart with multiple placement cavities on its top surface. Multiple partitions are slidably fitted within each placement cavity, dividing it into multiple empty placement chambers. Each partition has an internal cavity containing two rotating shafts rotatably connected to the partitions. Multiple rubber wheels are fixedly fitted onto each rotating shaft from bottom to top. One end of each rubber wheel passes through a slot and into a slide rail, pressing against the side wall of the slide rail. The slot is located on the side wall of the partition, and the slide rail is located on the side wall of the handcart and communicates with the placement cavities. A braking mechanism is located within each cavity, with its output end fitting against the top surface of the two rotating shafts. A round-headed bolt is threaded onto the top surface of each partition; rotating the downward-moving round-headed bolt pushes the braking mechanism to brake the rotating shafts.

[0007] Preferably, the height of the rubber wheel is equal to the height of the slide rail, and the top and bottom ends of the rubber wheel are respectively in contact with the surface of the slide rail.

[0008] Preferably, the braking mechanism includes a connecting rod disposed in the cavity. The connecting rod is in the shape of a "mountain", and there are two pairs of brake pads on the bottom surface of the connecting rod. Each pair of brake pads is composed of two brake pads stacked together. The top surface of the top brake pad is fixedly connected to the bottom surface of the connecting rod, and the bottom surface of the bottom brake pad is fixedly connected to the top surface of the rotating shaft. A plurality of guide rods are slidably disposed through the cross bar of the connecting rod, and the top ends of the guide rods all penetrate through the cross bar of the connecting rod and are fixedly connected to the surface of the partition plate. The bottom end of the round head bolt abuts against the top surface of the vertical rod in the middle of the connecting rod.

[0009] Preferably, tension springs are fixedly connected between the top surfaces of the vertical rods on both sides of the connecting rod and the partition plate.

[0010] Preferably, a cover plate is fitted on the top surface of the trolley. One side wall of the cover plate is hinged to the side wall of the trolley through a plurality of hinges, and the other side of the cover plate is connected to the side wall of the trolley through a buckle.

[0011] Preferably, a groove is formed on the top surface of the partition plate, and the screw head of the round head bolt is disposed in the groove and the top surface of the round head bolt is flush with the top surface of the partition plate.

[0022] To make the objectives and advantages of this utility model clearer, the utility model will be further described below with reference to the embodiments; it should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0023] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0024] It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0025] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] like Figures 1-7As shown, this utility model provides the following technical solution: a handcart that facilitates adjustment of the size of the placement cavity spacing, comprising a handcart 1, with multiple placement cavities 2 on the top surface of the handcart 1, and multiple partitions 3 slidably disposed within the placement cavities 2, the partitions 3 dividing the placement cavities 2 into multiple placement chambers, the size of the placement chambers being adjusted by sliding the partitions 3 to accommodate cores of different diameters, and cavities 4 being provided inside the partitions 3, with two rotating shafts 5 rotatably connected to the partitions 3. Multiple rubber wheels 6 are fixedly fitted on the rotating shaft 5 from bottom to top. One end of the rubber wheel 6 passes through the through groove 7 and into the slide rail 8 and is pressed against the side wall of the slide rail 8. The through groove 7 is opened on the side wall of the partition 3, and the slide rail 8 is opened on the side wall of the handcart 1 and communicates with the placement cavity 2. A braking mechanism is provided in the cavity 4, and the output end of the braking mechanism is in contact with the top surface of the two rotating shafts 5. A round head bolt 12 is threaded on the top surface of the partition 3. Rotating the downward moving round head bolt 12 can push the braking mechanism to brake the rotating shaft 5.

[0027] Please combine Figure 1 As shown, after the roll film in the handcart 1 is used up, the roll core is removed from the handcart 1 and placed in the placement cavity 2. Multiple partitions 3 divide the placement cavity 2 into multiple small placement cavities of different sizes. Then, the round-head bolt 12 is turned up, and the round-head bolt 12 moves upward, removing the limit on the brake mechanism and thus removing the limit on the rotating shaft 5. This allows the rotating shaft 5 to rotate in the through groove 7. Then, the partitions 3 are slid laterally to change the size of the placement cavities. The partitions 3 drive the rotating shaft 5 to move, and the rotating shaft 5 drives the rubber wheel 6 to roll in the slide rail 8. The slide rail 8 drives the rotating shaft 5 to rotate. The sliding partitions 3 and the roll core side... The wall-fitting mechanism clamps the core, preventing it from shaking during the movement of the handcart 1 and improving its stability. Then, the round-head bolt 12 is tightened to limit the braking mechanism, causing it to brake the rotating shaft 5. This prevents the shaft 5 from rotating, thus preventing the rubber wheel 6 from rotating. Consequently, the rubber wheel 6 cannot rotate within the slide rail 8, changing the friction between it and the slide rail 8 from rolling friction to sliding friction. This increases the friction between the rubber wheel 6 and the slide rail 8, preventing the rubber wheel 6 from sliding and thus limiting its movement. This effectively fixes the rubber wheel 6 to the slide rail 8.

[0028] The height of the rubber wheel 6 is equal to the height of the slide rail 8. The top and bottom ends of the rubber wheel 6 are respectively in contact with the surface of the slide rail 8. The slide rail 8 limits the rubber wheel 6 to prevent it from moving longitudinally. The inability of the rubber wheel 6 to move longitudinally prevents the rotating shaft 5 from moving longitudinally, thereby effectively preventing the partition 3 from moving longitudinally and indirectly preventing the partition 3 from sliding out of the placement cavity 2, making it convenient for the partition 3 to clamp the core.

[0029] Please combine Figures 3-5As shown in the figure, an embodiment of the braking mechanism. The braking mechanism includes a connecting rod 10 disposed in a cavity 4. The shape of the connecting rod 10 is like a Chinese character 'Shan' (mountain). There are two pairs of brake pads 9 provided on the bottom surface of the connecting rod 10. Each pair of brake pads 9 is composed of two brake pads 9 stacked together. The top surface of the top brake pad 9 is fixedly connected to the bottom surface of the connecting rod 10, and the bottom surface of the bottom brake pad 9 is fixedly connected to the top surface of a rotating shaft 5. A plurality of guide rods 13 are slidably disposed through the cross bar of the connecting rod 10. The top ends of the guide rods 13 all pass through the cross bar of the connecting rod 10 and are fixedly connected to the surface of a partition plate 3. The bottom end of a round head bolt 12 abuts against the top surface of the vertical rod in the middle of the connecting rod 10.

[0030] Please refer to Figure 3 As shown in the figure, when it is necessary to release the brake on the rotating shaft 5, turn the round head bolt 12 to gradually move upward. The bottom end of the round head bolt 12 cancels the extrusion on the connecting rod 10. The frictional force between the brake pads 9 fixed to the connecting rod 10 and the brake pads 9 fixed to the rotating shaft 5 becomes smaller. Then slide the partition plate 3. The partition plate 3 drives the rotating shaft 5 to slide. The rotating shaft 5 drives the rubber wheel 6 to roll in the slide rail 8. The rubber wheel 6 drives the rotating shaft 5 to rotate. The rotating shaft 5 drives the brake pads 9 fixed to it to rotate. When the partition plate 3 abuts against the side wall of the core, turn the round head bolt 12 to move downward. The bottom end of the round head bolt 12 presses the connecting rod 10. The connecting rod 10 drives the brake pads 9 fixed to it to press the brake pads 9 fixed to the rotating shaft 5, making the brake pads 9 fixed to the rotating shaft 5 unable to rotate. Thus, the rotating shaft 5 cannot rotate. The rotating shaft 5 cannot rotate, making the rubber wheel 6 fixed to it unable to rotate. The guide rods 13 play a guiding role in the movement of the connecting rod 10.

[0031] Tensile springs 11 are fixedly connected between the top surfaces of the vertical rods on both sides of the connecting rod 10 and the partition plate 3. When the round head bolt 12 rotates upward to move and cancels the extrusion on the connecting rod 10, at this time, the tensile spring 11 pulls the connecting rod 10 to move upward. The connecting rod 10 drives the brake pads 9 fixed to it to move upward to cancel the limit on the brake pads 9 fixed to the rotating shaft 5. The connecting rod 10 slides on the guide rods 13. When the round head bolt 12 rotates downward to push the connecting rod 10 to move downward, the connecting rod 10 drives the brake pads 9 fixed to it to move downward to abut against and press the brake pads 9 fixed to the rotating shaft 5, making the brake pads 9 fixed to the rotating shaft 5 unable to rotate. The brake pads 9 fixed to the rotating shaft 5 being unable to rotate makes the rotating shaft 5 unable to rotate. The rotating shaft 5 being unable to rotate makes the rubber wheel 6 unable to rotate.

[0032] A cover plate 15 is fitted to the top surface of the handcart 1. One side wall of the cover plate 15 is hinged to the side wall of the handcart 1 by multiple hinges, and the other side of the cover plate 15 is connected to the side wall of the handcart 1 by a buckle. When the core needs to be placed in the placement cavity 2, the cover plate 15 hinged to the top of the placement cavity 2 is opened, and then the core is placed in the placement cavity 2. The core is positioned by the sliding partition 3 so that the core cannot shake. The cover plate 15 covers the core placed in the placement cavity 2, which increases the aesthetics of the handcart 1.

[0033] The top surface of the partition 3 has a groove 14, and the head of the round-head bolt 12 is set in the groove 14, with the top surface of the round-head bolt 12 and the top surface of the partition 3 on the same plane. Figure 7 As shown, the cover plate 15 can cover the placement cavity 2 to prevent the top of the round head bolt 12 from lifting the cover plate 15.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
