Description

Technical Field

[0001] This application relates to the field of commodity distribution, and more particularly, to a device for logistics distribution. Background Art

[0002] Commodity distribution refers to a series of activities in which a large number of multi-variety commodities received from suppliers are stored as necessary, and after sorting, selecting, sorting, processing, packaging and other distribution activities according to the order requirements of users, the sorted commodities are safely and accurately delivered to users within the specified time.

[0003] For example, the Chinese patent publication number is CN113577745A, and the technical solution disclosed in this patent document is as follows: A sports equipment transportation device for physical education teaching with a classification function. The technical problem to be solved by the present invention is that it is difficult to clean and classify different-sized balls by itself, and can only store them quantitatively. It is difficult to carry and use the stored balls as a single category as a whole, and it is difficult to automatically clean and store rod-shaped sports equipment. To solve the above technical problems, the present invention provides a sports equipment transportation device for physical education teaching with a classification function. The present invention is composed of a sub-storage mechanism and a self-care mechanism, which can quickly clean the mixed balls and classify and store them according to size, reducing the collection difficulty for users and making it more convenient to use. It can work continuously by replacing the storage cylinder, and there is no need to move the whole device when taking balls, making it more flexible to use. It can automatically clean rod-shaped sports equipment and store them in the placement slots in sequence, greatly improving the overall collection, transportation and storage efficiency.

[0004] The following problems exist in the prior art: Although the classification and cleaning functions of sports equipment are realized, due to the different types, shapes and weights of the equipment, it may lead to unstable storage of the equipment during storage and handling. Especially when dealing with heavier or irregular equipment, problems such as large differences in weight or volume may be encountered during the classified storage of the equipment. Especially when the device needs to store various types of sports equipment, it may lead to inconvenient or unstable storage. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a device for logistics distribution, which solves the problems raised in the above background art.

[0006] To achieve the above object, the present application provides a logistics distribution device, including a base. The upper end of the base is fixedly connected with a box body. The bottom of the base is provided with a moving component. The moving component includes a fixed block. The fixed block is fixedly connected to the bottom of the base. A transmission rod is rotatably connected between every two fixed blocks. The two ends of the transmission rod are fixedly connected with moving wheels. The upper end of the base is fixedly connected with a push handle. The inside of the box body is provided with a storage device. The storage device includes a support seat. The support seat is fixedly connected to the bottom end inside the box body. An arc-shaped groove A is opened at the upper end of the support seat. An arc-shaped groove B and an arc-shaped groove C are opened inside the support seat. A rubber plate is arranged inside the arc-shaped groove C. A sliding shaft is slidably connected inside the arc-shaped groove B. The upper end of the sliding shaft is fixedly connected with a connecting plate. The upper end of the connecting plate is fixedly connected with a storage box. The arc-shaped groove B is located at the lower end of the arc-shaped groove A. The arc-shaped groove C is located at the lower end of the arc-shaped groove B. An adjusting device is arranged at the bottom of the base and inside the box body. The main function of the adjusting device is to change the friction force between the rubber plate and the sliding shaft by adjusting the position of the lifting plate, so as to adjust the position of the storage box to adapt to the storage of commodities of different weights. When storing heavier items, the gravity inside the storage box may cause insufficient friction force between the sliding shaft and the rubber plate, unable to effectively support the items. At this time, the adjusting device operates through the foot pedal, so that the telescopic rod drives the lifting plate to rise, and then pushes the rubber plate to rise, increasing the friction force between the sliding shaft and the rubber plate, ensuring the stability of the storage box and preventing the items from sliding. When storing commodities of different weights, the height change of the lifting plate can automatically adjust the position of the storage box. If the load of the storage box is heavier, after the friction force increases, the sliding shaft will slide along the arc-shaped groove, pushing the storage box to move closer to the center position of the box body, so as to ensure the stable storage of the commodities. If the commodities are lighter, the friction force is smaller, and the sliding shaft is not easy to slide, and the storage box remains in the original position. When manual pushing is required, the adjusting device allows the operator to easily adjust the position of the rubber plate through the foot pedal, thereby affecting the friction force of the sliding shaft and further affecting the stability of the storage box.For the stability of the device movement, the adjusting device ensures that the movement of the trolley remains smooth and reliable even under load changes. The adjusting device includes two mounting blocks, the two mounting blocks are fixedly connected to the bottom of the base, a rotating shaft is rotatably connected between the two mounting blocks, a telescopic rod is fixedly sleeved on the outer wall of the rotating shaft, one end of the telescopic rod is fixedly connected to a foot pedal, the other end of the telescopic rod is hinged to a lifting plate, the bottom of the base is fixedly connected to an L-shaped plate, a spring A is fixedly connected to the upper end of the L-shaped plate, the upper end of the spring A is fixedly connected to the bottom of the lifting plate, an installation groove is formed in the outer wall of the lifting plate, a spring B is fixedly connected to the inside of the installation groove, the other end of the spring B is fixedly connected to a moving block, an active block is fixedly connected to the outer side end of the moving block, the bottom of the base is fixedly connected to a fixing plate, a clamping block is fixedly connected to the outer wall of the fixing plate, a spring C is fixedly connected to the upper end of the clamping block, and a slider is fixedly connected to the upper end of the spring C.

[0007] Preferably, the moving block is slidably connected to the inside of the installation groove, and the slider is slidably connected to the outer wall of the fixing plate.

[0008] Preferably, the top of the lifting plate slidably penetrates through the base, the box body and the support seat, and rubber plates are fixedly connected to both sides of the lifting plate.

[0009] Preferably, two connecting plates and sliding shafts are provided at the bottom of each storage box.

[0010] Preferably, a buffer assembly is provided inside the box body. The design of the buffer assembly is mainly to slow down the impact force that may be generated during the descent of the storage box, avoiding damage to the storage box or the internal goods. When the storage box is in a descending state, the buffer assembly will play a role in slowing down the descent speed. Especially after heavy objects are placed, the storage box may fall too fast due to gravity. At this time, the spring of the buffer assembly will gradually slow down the movement speed of the storage box through the restoring force, reducing the impact force and preventing the storage box from colliding violently with the bottom. Through the design of the spring and the sliding part, the buffer assembly can effectively absorb the impact force generated during the fall of the storage box. When the storage box falls, the buffer plate will be squeezed, driving the sliding part to slide on the fixed rod, thereby generating an elastic reaction force. This reaction force helps to slow down the falling speed and finally absorbs the impact force of the storage box, avoiding damage, effectively preventing the violent vibration of the storage box caused by falling too fast, contributing to maintaining the stability of the equipment, and improving the safety of commodity storage. Especially when storing fragile items, the buffer system can greatly reduce the risk of breakage. The buffer assembly includes a receiving groove, which is opened on the outer wall of the lifting plate. A fixed rod is fixedly connected inside the receiving groove. A sliding part is slidably connected to the outer wall of the fixed rod. A spring D is movably sleeved on the outer wall of the fixed rod. The two ends of the spring D are respectively fixedly connected to the inner wall of the receiving groove and the sliding part. A connecting rod is hinged to the outer wall of the sliding part, and the other end of the connecting rod is hinged to the buffer plate.

[0011] Preferably, a retaining rod is fixedly connected to the inner wall of the box body, and the retaining rod is in close contact with the outer wall of the buffer plate.

[0012] Preferably, a braking assembly is provided at the bottom of the base. The function of the braking assembly is to ensure that the transmission rod remains stable and does not rotate accidentally when it does not need to move. When it is necessary to fix the device in a position, the braking assembly makes the transmission rod stationary through the friction between the braking block and the transmission rod, preventing unnecessary rotation during operation. Especially when the cart is moving, if it is necessary to fix the device in a certain position, the braking assembly can provide a strong blocking effect to ensure the stability of the device. The anti-slip pattern design at the bottom of the braking block increases the friction between the braking block and the transmission rod, thereby improving the braking effect. Especially when the device has a heavy load, the braking effect can effectively avoid accidental rotation of the transmission rod, ensuring that the entire device does not slide or tilt in a stationary state. The braking assembly is started by stepping on the foot pedal and can automatically adjust the position of the braking block through the cooperation of the roller and the cam. The braking effect can be started quickly, and when the foot pedal is released, the system will automatically release the brake through the restoring action of the spring to ensure the flexibility of the device. The braking assembly includes a cam, the cam is fixedly sleeved on the outer wall of the rotating shaft, the bottom of the base is fixedly connected with an L-shaped rod, the upper end of the L-shaped rod is provided with a moving rod and the bottom of the moving rod slides through the L-shaped rod, both ends of the moving rod are respectively fixedly connected with a circular block and a braking block, the outer wall of the circular block is fixedly sleeved with a spring E, both ends of the spring E are respectively fixedly connected with the circular block and the L-shaped rod, and a roller is provided at the upper end of the circular block.

[0013] Preferably, the braking block and the transmission rod are located in the same vertical plane and the bottom of the braking block is provided with an anti-slip pattern.

[0014] The advantages of this application are as follows: (1) The main function of the adjustment device in this application is to change the friction between the rubber plate and the sliding shaft by adjusting the position of the lifting plate, thereby adjusting the position of the storage box to accommodate the storage of goods of different weights. When storing heavier items, the gravity inside the storage box may cause insufficient friction between the sliding shaft and the rubber plate, unable to effectively support the items. At this time, the adjustment device operates through the foot pedal, causing the telescopic rod to drive the lifting plate to rise, and then pushing the rubber plate upward to increase the friction between the sliding shaft and the rubber plate, ensuring the stability of the storage box and preventing the items from sliding. When storing goods of different weights, the height change of the lifting plate can automatically adjust the position of the storage box. If the load of the storage box is heavy, after the friction increases, the sliding shaft will slide along the arc-shaped groove, pushing the storage box towards the center position of the box body, thus ensuring the stable storage of goods. If the goods are light, the friction is small, and the sliding shaft is not easy to slide, and the storage box remains in its original position. When manual pushing is required, the adjustment device allows the operator to easily adjust the position of the rubber plate through the foot pedal, thereby affecting the friction of the sliding shaft and further affecting the stability of the storage box. For the stability of the device movement, the adjustment device ensures that even under load changes, the movement of the cart remains stable and reliable.

[0015] (2) The design of the buffer component in this application is mainly to reduce the impact force that may be generated during the descent of the storage box, preventing damage to the storage box or the internal goods. When the storage box is in the descending state, the buffer component will come into play and slow down the descending speed. Especially after placing heavy objects, the storage box may fall too fast due to gravity. At this time, the spring of the buffer component will gradually slow down the movement speed of the storage box through the restoring force, reducing the impact force and preventing the storage box from colliding violently with the bottom. Through the design of the spring and the sliding part, the buffer component can effectively absorb the impact force generated during the descent of the storage box. When the storage box falls, the buffer plate will be squeezed, driving the sliding part to slide on the fixed rod, thereby generating an elastic reaction force. This reaction force helps to slow down the falling speed and finally absorbs the impact force of the storage box, preventing damage, effectively preventing the violent vibration caused by the storage box falling too fast, helping to maintain the stability of the equipment, and enhancing the safety of commodity storage. Especially when storing fragile items, the buffer system can greatly reduce the risk of breakage.

[0016] (3) The function of setting the brake assembly in this application is to ensure that the transmission rod remains stable and does not rotate accidentally when it does not need to move. When it is necessary to fix the device in a position, the brake assembly makes the transmission rod stay stationary through the friction between the braking block and the transmission rod, preventing unnecessary rotation during operation. Especially when the cart is moving, if it is necessary to fix the device in a certain position, the brake assembly can provide a strong blocking effect to ensure the stability of the device. The anti-slip pattern design at the bottom of the braking block increases the friction between the braking block and the transmission rod, thereby improving the braking effect. Especially when the device has a heavy load, the braking effect can effectively prevent the accidental rotation of the transmission rod, ensuring that the entire device does not slide or tilt in the stationary state. The brake assembly is started by stepping on the foot pedal and can automatically adjust the position of the braking block through the cooperation of the roller and the cam. The braking effect can be started quickly, and when the foot pedal is released, the system will automatically release the brake through the restoring action of the spring to ensure the flexibility of the equipment.

[0025] Embodiment 1

[0026] See Figures 1 - 4, this embodiment provides a logistics distribution device, including a base 1. The base 1 is the foundation of the entire distribution device, providing a stable support platform for the box body 2 and other components, offering stable support to ensure that the working environment of the entire system is not interfered by the outside world. The upper end of the base 1 is fixedly connected with a box body 2. The box body 2 is the main space for storing goods, accommodating the storage device 5, storing goods, and adjusting the friction of the storage device 5 through cooperation with the adjustment device 6 to ensure that goods of different weights can be effectively stored. It is fixed at the upper end of the base 1 to ensure the safe storage of goods. A moving component 3 is arranged at the bottom of the base 1. Its main function is to enable the base 1 to move on a horizontal plane, facilitating the flexible scheduling of the device in the sports field. The moving component 3 includes a fixed block 31, providing a fixed point for the transmission rod 32. The fixed block 31 is fixedly connected to the bottom of the base 1. A transmission rod 32 is rotatably connected between every two fixed blocks 31, connecting the moving wheels 33 to transmit power and make the wheels rotate. The two ends of the transmission rod 32 are fixedly connected with the moving wheels 33. A push handle 4 is fixedly connected to the upper end of the base 1, used to push the device to move, especially when not relying on automatic control, facilitating manual operation. A storage device 5 is arranged inside the box body 2. The storage device 5 is the core part inside the box body 2, used to actually store sports goods. The storage device 5 includes a support base 51. The support base 51 is fixedly connected to the inner bottom end of the box body 2. An arc-shaped groove A52 is opened at the upper end of the support base 51. An arc-shaped groove B53 and an arc-shaped groove C58 are opened inside the support base 51. A rubber plate 54 is arranged inside the arc-shaped groove C58. A sliding shaft 55 is slidably connected inside the arc-shaped groove B53. The upper end of the sliding shaft 55 is fixedly connected with a connecting plate 56. The upper end of the connecting plate 56 is fixedly connected with a storage box 57. The arc-shaped groove B53 is located at the lower end of the arc-shaped groove A52, and the arc-shaped groove C58 is located at the lower end of the arc-shaped groove B53. An adjustment device 6 is arranged at the bottom of the base 1 and inside the box body 2. The function of the adjustment device 6 is to change the friction between the rubber plate 54 and the sliding shaft 55 by adjusting the position of the lifting plate 67, thereby controlling the position of the storage box 57 to adapt to the storage of goods of different weights. The adjustment device 6 includes two mounting blocks 61. The two mounting blocks 61 are fixedly connected to the bottom of the base 1. A rotating shaft 62 is rotatably connected between the two mounting blocks 61. An expansion link 63 is fixedly sleeved on the outer wall of the rotating shaft 62. One end of the expansion link 63 is fixedly connected with a foot pedal 64. The other end of the expansion link 63 is hinged with a lifting plate 67. An L-shaped plate 65 is fixedly connected to the bottom of the base 1. A spring A66 is fixedly connected to the upper end of the L-shaped plate 65. The upper end of the spring A66 is fixedly connected with the bottom of the lifting plate 67. An installation groove 68 is opened on the outer wall of the lifting plate 67. A spring B610 is fixedly connected inside the installation groove 68. The other end of the spring B610 is fixedly connected with a moving block 69. The outer end of the moving block 69 is fixedly connected with a movable block 611. A fixed plate 612 is fixedly connected to the bottom of the base 1. A clamping block 613 is fixedly connected to the outer wall of the fixed plate 612.The upper end of the clamping block 613 is fixedly connected to spring C 615, and spring C 615 assists the slider 614 to reset. The upper end of spring C 615 is fixedly connected to the slider 614. The moving block 69 is slidably connected inside the installation groove 68, and the slider 614 is slidably connected to the outer wall of the fixing plate 612. The top of the lifting plate 67 slidably penetrates through the base 1, the box body 2 and the support seat 51, and rubber plates 54 are fixedly connected to both sides of the lifting plate 67. Two connecting plates 56 and sliding shafts 55 are arranged at the bottom of each storage box 57.,

[0027] During use, when no sports goods are placed in the storage box 57, the sliding shaft 55, the connecting plate 56 and the storage box 57 will be located on both sides inside the box body 2. After placing heavier sports goods inside the storage box 57, the frictional force between the sliding shaft 55 and the rubber plate 54 is not sufficient to keep the sliding shaft 55 stationary. Then, the sliding shaft 55 will slide towards the middle inside the arc-shaped groove B 53, thereby driving the connecting plate 56 and the upper storage box 57 to move towards the middle of the box body 2. When it is necessary to adjust the position of the rubber plate 54 and the frictional force between the rubber plate 54 and the sliding shaft 55, by stepping on the foot pedal 64 downward, the foot pedal 64 will drive the telescopic rod 63 to rotate through the rotating shaft 62. Then, the lifting plate 67 at the other end of the telescopic rod 63 will move upward accordingly. At the same time, the movable block 611 on the side of the lifting plate 67 will contact the clamping block 613. Then, the movable block 611 will push the moving block 69 to squeeze the spring B 610 and move into the installation groove 68. When the movable block 611 moves upward to not contact the moving block 69, the spring B 610 will push the moving block 69 and the movable block 611 to move outward. Then, the bottom of the movable block 611 will contact the upper end of the clamping block 613, thereby realizing the limit of the movable block 611 and the lifting plate 67. Then, the lifting plate 67 can drive the rubber plate 54 to rise, thereby increasing the frictional force between the sliding shaft 55 and the rubber plate 54, so that more sports goods can be placed inside the storage box 57 before displacement occurs. When it is necessary to reset the lifting plate 67, continue to step on the foot pedal 64 downward. Then, the foot pedal 64 will drive the telescopic rod 63 to continue to rotate through the rotating shaft 62. Then, the lifting plate 67 at the other end of the telescopic rod 63 will continue to move upward. Then, the movable block 611 will contact the slider 614. After that, the movable block 611 will continue to drive the moving block 69 to squeeze the spring B 610 and enter the installation groove 68 again. When the movable block 611 moves to the upper end of the slider 614, release the foot pedal 64. Under the action of spring A 66, it will pull the lifting plate 67 to reset. Then, the movable block 611 will drive the slider 614 to squeeze the spring C 615 and slide downward. When the slider 614 is close to contacting the clamping block 613, the movable block 611 will slide downward from the outer wall of the slider 614 to the outer wall of the clamping block 613. Then, the movable block 611 will reset to the bottom of the clamping block 613, thereby making the lifting plate 67 reset.,

[0028] Example 2

[0029] Refer to Figures 1 - 5 , a buffer assembly 7 is arranged inside the box body 2. The addition of the buffer assembly 7 is to prevent the storage box 57 from being damaged or affecting normal operation due to excessive impact during the descending process. The buffer assembly 7 includes a receiving groove 71, which is opened on the outer wall of the lifting plate 67. A fixing rod 72 is fixedly connected inside the receiving groove 71. A sliding member 73 is slidably connected to the outer wall of the fixing rod 72. A spring D74 is movably sleeved on the outer wall of the fixing rod 72. Two ends of the spring D74 are respectively fixedly connected to the inner wall of the receiving groove 71 and the sliding member 73. A connecting rod 75 is hinged to the outer wall of the sliding member 73. The other end of the connecting rod 75 is hinged to a buffer plate 76. A stop rod 77 is fixedly connected to the inner wall of the box body 2, and the stop rod 77 is in close fit with the outer wall of the buffer plate 76.

[0030] During use, when the lifting plate 67 rises, the buffer assembly 7 also rises as a whole. The rise of the lifting plate 67 triggers the activity of the entire buffer system, causing the buffer plate 76 to gradually rise. As the buffer assembly 7 rises, the buffer plate 76 also moves upward. At this time, the buffer plate 76 will separate from the stop lever 77, releasing its original contact state. The stop lever 77 usually plays a restrictive role to ensure that the buffer plate 76 is in a certain specific position. When the buffer plate 76 rises and separates from the stop lever 77, the restrictive effect on the spring D74 also disappears. The spring D74 was originally in a compressed state, restricting the movement of the sliding member 73. When the buffer plate 76 separates from the stop lever 77, the spring D74 will quickly return to its original state, pushing the sliding member 73 to slide towards the middle on the outer wall of the fixed rod 72. The movement of the sliding member 73 is crucial in the system because it drives a series of subsequent actions. The bottom of the connecting rod 75 hinged to the outer wall of the sliding member 73 will approach each other when the sliding member 73 moves towards the middle. The other end of the connecting rod 75 will push the buffer plate 76 to move outward. The design of the connecting rod 75 is to convert the movement of the sliding member 73 into the lateral displacement of the buffer plate 76, thereby adjusting the relative position of the buffer plate 76. The storage box 57 is connected to the sliding shaft 55 through the connecting plate 56 and slides along the middle direction under the guidance of the arc-shaped groove B53. When the storage box 57 descends too fast, it may impact with the buffer plate 76. At this time, the gravity or kinetic energy of the storage box 57 will be transmitted to the buffer plate 76, causing the buffer plate 76 to be impacted by an external force. After being impacted, the buffer plate 76 transmits the impact force to the sliding member 73 through the connecting rod 75. After being acted upon by an external force, the sliding member 73 will move towards both sides along the outer wall of the fixed rod 72 and compress the spring D74. The compression of the spring D74 is the core of the buffer system. It gradually slows down the movement speed of the storage box 57 through the restoring force, thereby playing an effective shock absorption and buffering role. Due to the compression of the spring D74, frictional force and elastic reaction force are generated during the movement of the sliding member 73, so that the falling speed of the storage box 57 is slowed down and the impact force is gradually absorbed. In this way, the entire system can effectively control the descending speed of the storage box 57 and prevent it from colliding or being damaged too quickly.

The brake assembly 8 is used to fix the transmission rod 32 to prevent it from rotating and ensure the stability of the device when needed. The brake assembly 8 includes a cam 81. The cam 81 is fixedly sleeved on the outer wall of the rotating shaft 62. An L-shaped rod 82 is fixedly connected to the bottom of the base 1. A moving rod 83 is provided at the upper end of the L-shaped rod 82, and the bottom of the moving rod 83 slidably penetrates through the L-shaped rod 82.

Both ends of the spring E86 are fixedly connected to the circular block 84 and the L-shaped rod 82 respectively. A roller 87 is provided at the upper end of the circular block 84, which contacts the cam 81 to control the position of the braking block 85. The braking block 85 and the transmission rod 32 are in the same vertical plane, and anti-slip lines 88 are provided at the bottom of the braking block 85 to increase the friction between the braking block 85 and the transmission rod 32 and ensure the braking effect.

[0033] During use, when the foot pedal 64 is stepped on, it will drive the rotating shaft 62 to rotate through the telescopic rod 63. Then, the rotating shaft 62 will drive the cam 81 to rotate. When the contact part between the cam 81 and the lower roller 87 changes from a concave part to a convex part, it will push the roller 87 downward, thereby driving the moving rod 83 downward. Then, the circular block 84 and the braking block 85 at the bottom of the moving rod 83 will move downward, and the bottom of the braking block 85 will abut against the outer wall of the transmission rod 32. Thus, when the adjusting device 6 operates, the transmission rod 32 can be prevented from rotating. At the same time, the anti-slip lines 88 can increase the friction between the braking block 85 and the transmission rod 32, thereby ensuring the braking effect. When the foot pedal 64 is continuously stepped on, the rotating shaft 62 will still continue to rotate. At this time, the contact part between the roller 87 and the cam 81 is still a convex part. Therefore, the braking block 85 will continue to abut against the transmission rod 32. When the foot pedal 64 is released and the lifting plate 67 is reset, the rotating shaft 62 will rotate in the reverse direction. Then, when the lifting plate 67 is reset, the contact part between the roller 87 and the cam 81 will change back to a concave part. Then, under the action of the spring E86, it will push the circular block 84 and the moving rod 83 itself upward, and then the braking block 85 will also move away from the transmission rod 32.
