Description

Technical Field

[0001] This invention relates to the field of logistics transportation technology, and in particular to a roller for logistics transportation tracks that is easy to assemble and disassemble. Background Technology

[0002] With the rapid development of e-commerce and IoT technology, logistics plays a very important role, and more and more people are getting involved in it. Logistics transportation technology mainly includes two categories: transportation facilities and transportation operations. The former belongs to transportation hard technology, while the latter belongs to transportation soft technology. Transportation hard technology mainly includes transportation infrastructure, including logistics transmission tracks, which require the use of rollers.

[0003] A search revealed that Chinese patent number CN113044469A discloses an intelligent logistics transmission mechanism. Although it enables the sorting and classification of goods based on information content, reducing manpower consumption and damage to goods during the sorting process, the rollers on its logistics transmission track are difficult to disassemble and assemble, making it impossible to quickly repair or reassemble the logistics transmission track. This not only affects the efficiency of logistics transmission but also increases unnecessary manpower consumption, resulting in device defects. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a roller for logistics transport tracks that is easy to assemble and disassemble.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A detachable and assembleable roller for a logistics transport track includes a first roller and a second roller. A rotating shaft is slidably sleeved on the end face of the first roller and the second roller, and a retaining strip is fixed to the outer surface of the rotating shaft. A cavity 2 is opened on the end face of the first roller and the second roller, and a pull rod is slidably sleeved on the top wall of the cavity 2. A spring is installed between the pull rod and the side wall of the cavity 2, and a retaining rod is fixed to the other side of the pull rod. A retaining groove 2 is opened on the outer surface of the rotating shaft, and a movable disk is fixed to the end face of the rotating shaft.

[0007] Furthermore, the movable disk is slidably sleeved with the inner cavities of the first and second dividing rollers respectively, and the end face of the locking rod is an inclined arc surface, and the locking rod is engaged with the second locking groove.

[0008] Furthermore, the pull rod is T-shaped, and both the first and second sub-rollers are driven by the pull rod and spring to move the locking rod. The locking strips are respectively fitted and connected to the end faces of the first and second sub-rollers, and the locking strips are evenly distributed about the central axis of the rotating shaft. The second locking groove is located between the locking strips.

[0009] Furthermore, a guide rod is provided between the corresponding surfaces of the first and second rollers. Grooves are respectively formed on the outer surfaces of the first and second rollers. Limiting grooves are formed on the side walls of the grooves. Telescopic plates are respectively fixed to the corresponding surfaces of the first and second rollers. A cavity is formed inside the telescopic plate. A rotating block is rotatably sleeved on the top wall of the cavity. A slot is formed at one end of the rotating block. A bidirectional screw is fixed to the other end of the rotating block. Moving blocks one and two are respectively engaged at both ends of the bidirectional screw. A slider is fixed to one side of each of the moving blocks one and two. A top rod is hinged to the other side of each of the moving blocks one and two. A limiting block is hinged to the other end of the top rod. Scale lines are engraved on the outer surface of the telescopic plate.

[0010] Furthermore, the telescopic plate is slidably sleeved with the groove, the limiting block penetrates the side wall of cavity one, and the limiting block is slidably sleeved with the limiting groove, and the side wall of the limiting block facing the corresponding surfaces of the first and second rollers is flush with the scale on the scale line.

[0011] Furthermore, the central axis of the rotating block is flush with the scale on the scale line, the cross-section of the first slot is rectangular, the guide rod is fixedly connected to the first sub-roller, and the guide rod is slidably connected to the second sub-roller.

[0012] Furthermore, the telescopic plates are provided in two sets, and the two sets of telescopic plates are symmetrically arranged about the central axes of the first and second sub-rollers, respectively.

[0013] Furthermore, the slider is slidably sleeved with the side wall of cavity one, the telescopic plate restricts the rotation of moving block one and moving block two through cavity one and slider, and the bidirectional screw is rotatably connected to the side wall of cavity one.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. This invention uses the locking rod and the second locking groove to fix the extension length of the rotating shaft, thereby completing the installation of the roller. When it is necessary to disassemble the roller, simply pull the lever and slide it along the second cavity, so that the lever drives the locking rod to separate from the rotating shaft again, releasing the fixing of the rotating shaft, and retracting the rotating shaft to complete the disassembly of the roller. This makes the disassembly and assembly of the roller simple, so that the logistics transmission track can be quickly inspected or assembled, which not only ensures the efficiency of logistics transmission, but also reduces unnecessary manpower consumption.

[0016] 2. This invention uses an external wrench to rotate a rotating block, causing the bidirectional screw on the rotating block to rotate. The two movable blocks on the bidirectional screw, being restricted by the slider, cannot rotate, causing them to move in opposite directions. This causes one end of the push rod to move in opposite directions, resulting in the other end of the push rod pressing against the limiting block. This causes the limiting block to extend out of cavity one and engage with the limiting groove. Then, the two sub-rollers are pulled in opposite directions, causing the telescopic plates on them to extend out of the grooves until the limiting block contacts the sidewall of the limiting groove. This extends the length of the roller, making it suitable for the needs of logistics transport tracks, thus expanding the application range and improving the roller's applicability. It eliminates the need for custom-made rollers, reducing costs and preventing delays in logistics transport. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

Therefore, they should not be construed as limitations on this invention.

[0027] Example 1:

[0028] Please see Figure 1 , 3 -4 and Figure 6 This invention provides a technical solution: a roller for easy assembly and disassembly of a logistics transport track, comprising a first roller 1 and a second roller 3. A rotating shaft 17 is slidably sleeved on the end faces of the first roller 1 and the second roller 3, respectively. A retaining strip 18 is fixedly connected to the outer surface of the rotating shaft 17. A second cavity 19 is formed on the end faces of the first roller 1 and the second roller 3, respectively. A pull rod 20 is slidably sleeved on the top wall of the second cavity 19. A spring 21 is installed between the pull rod 20 and the side wall of the second cavity 19, and a retaining rod 22 is fixedly connected to the other side of the pull rod 20. The outer surface of the rotating shaft 17 is provided with… There is a second slot 23, and a movable disk 24 is fixedly connected to the end face of the rotating shaft 17. The movable disk 24 is slidably sleeved with the inner cavity of the first roller 1 and the second roller 3 respectively. The end face of the locking rod 22 is an inclined arc surface, and the locking rod 22 is engaged with the second slot 23. The pull rod 20 is T-shaped. The first roller 1 and the second roller 3 are both driven by the pull rod 20 and the spring 21 to move the locking rod 22. The locking strips 18 are respectively fitted and connected to the end faces of the first roller 1 and the second roller 3, and the locking strips 18 are evenly distributed about the central axis of the rotating shaft 17. The second slot 23 is located between the locking strips 18.

[0029] Specifically, during the process of disassembling and assembling the rollers on the logistics conveyor track, the rollers are placed between the logistics conveyor tracks, and one end of the rotating shaft 17 is pulled, causing the rotating shaft 17 to extend out from the first roller 1 and the second roller 3, and engage with the inner wall of the logistics conveyor track. During this process, the rotating shaft 17 always restricts the locking rod 22, causing the locking rod 22 to always retract into the second cavity 19 and compress the spring 21, until the second slot 23 on the rotating shaft 17 moves to the locking rod 22, thereby releasing the restraint of the locking rod 22 and compressing the spring 21. The roller springs back and engages with the second slot 23 to fix the rotating shaft 17, thus completing the installation of the roller. When it is necessary to disassemble the roller, simply pull the pull rod 20 and slide it along the second cavity 19, so that the pull rod 20 drives the locking rod 22 to separate from the rotating shaft 17 again, releasing the fixing of the rotating shaft 17, and retracting the rotating shaft 17 to complete the disassembly of the roller. This makes the disassembly and assembly of the roller simple, so that the logistics transmission track can be quickly inspected or assembled, which not only ensures the efficiency of logistics transmission, but also reduces unnecessary manpower consumption.

[0030] Example 2:

[0031] Please see Figure 1-2 and Figure 5 This invention provides a technical solution: a roller for easy assembly and disassembly of a logistics transport track. A guide rod 2 is provided between the corresponding surfaces of roller 1 and roller 2. Grooves 5 are respectively formed on the outer surfaces of roller 1 and roller 2. Limiting grooves 6 are formed on the sidewalls of the grooves 5. Telescopic plates 4 are fixedly connected to the corresponding surfaces of roller 1 and roller 2. A cavity 7 is formed inside the telescopic plate 4. A rotating block 8 is rotatably sleeved on the top wall of the cavity 7. A slot 9 is formed at one end of the rotating block 8. A bidirectional screw 10 is fixedly connected to the other end of the rotating block 8. Moving blocks 11 and 2 are respectively engaged and sleeved at both ends of the bidirectional screw 10. A slider 13 is fixedly connected to one side of each moving block 11 and moving block 2. A top rod 14 is hinged to the other side of each moving block 11 and moving block 2. The other end of the top rod 14 is hinged to a limiting groove. Block 15, and the outer surface of the telescopic plate 4 is engraved with scale lines 16. The telescopic plate 4 is slidably sleeved with the groove 5. The limiting block 15 penetrates the side wall of cavity 1 7 and is slidably sleeved with the limiting groove 6. The side wall of the limiting block 15 facing the corresponding surfaces of the first and second rollers 3 is flush with the scale on the scale line 16. The central axis of the rotating block 8 is flush with the scale on the scale line 16. The cross-section of the slot 1 9 is rectangular. The guide rod 2 is fixed to the first roller 1 and slidably sleeved with the second roller 3. Two sets of telescopic plates 4 are provided, and the two sets of telescopic plates 4 are symmetrically arranged about the central axes of the first and second rollers 3, respectively. The slider 13 is slidably sleeved with the side wall of cavity 1 7. The telescopic plate 4 restricts the rotation of the first moving block 11 and the second moving block 12 through cavity 1 7 and slider 13. The bidirectional screw 10 is rotatably connected to the side wall of cavity 1 7.

[0032] Specifically, in adjusting the roller length, the spacing between the logistics conveying tracks is first determined to determine the required roller length. If the roller length cannot meet the requirements of the logistics conveying tracks, the required extension length of the roller is determined, and then divided by 2 to obtain the required extension lengths of sub-rollers 1 and 3. Next, the rotating block 8 is determined according to the scale line 16. Then, the external wrench is engaged with the slot 9, and the rotating block 8 is rotated using the external wrench, causing the bidirectional screw 10 on the rotating block 8 to rotate. The moving blocks 11 and 12 on the bidirectional screw 10 are restricted by the slider 13 and cannot rotate, thus preventing the moving blocks 11 and 12 from rotating. 2. The opposing movement causes one end of the top rod 14 to move in opposite directions, causing the other end of the top rod 14 to press against the limiting block 15. This causes the limiting block 15 to extend out of the cavity 7 and engage with the limiting groove 6. At this point, the first and second sub-rollers 1 and 2 are pulled to both ends, causing the telescopic plates 4 on the first and second sub-rollers 1 and 2 3 to extend out of the grooves 5 until the limiting block 15 contacts the side wall of the limiting groove 6. This achieves the purpose of extending the roller, making the length of the roller meet the needs of the logistics transmission track, thereby expanding the application range of the roller and improving its applicability. There is no need to customize the roller, which not only reduces the cost input but also avoids delaying the logistics transmission.

[0033] The working principle and usage process of this invention are as follows: When rollers need to be installed on the logistics conveyor track, the spacing between the logistics conveyor tracks is first determined to determine the required length of the rollers. If the length of the rollers cannot meet the requirements of the logistics conveyor track, the length that the rollers need to be extended is determined, and then divided by 2 to obtain the length that sub-rollers 1 and 2 need to be extended. Then, the rotating block 8 that needs to be rotated is determined according to the scale line 16. Then, the external wrench is engaged with the slot 19, and the rotating block 8 is rotated by the external wrench, so that the bidirectional screw 10 on the rotating block 8 rotates. The moving blocks 11 and 2 on the bidirectional screw 10 are restricted by the slider 13 and cannot rotate, so that the moving blocks 11, 12 and 13 cannot rotate. 1 and 2 moving blocks 12 move in opposite directions, thereby driving one end of the top rod 14 to move in opposite directions, causing the other end of the top rod 14 to press against the limiting block 15, which in turn causes the limiting block 15 to extend out of the cavity 7 and engage with the limiting groove 6. At this time, the first roller 1 and the second roller 3 are pulled to both ends, causing the telescopic plates 4 on the first roller 1 and the second roller 3 to extend out of the grooves 5 respectively, until the limiting block 15 contacts the side wall of the limiting groove 6, thereby extending the roller and making the length of the roller meet the needs of the logistics transmission track, thus expanding the application range of the roller and improving the applicability of the roller. There is no need to re-customize the roller, which not only reduces the cost input, but also avoids delaying the logistics transmission.

[0034] After the above steps are completed, the rotating block 8 is rotated further, indirectly causing the moving block 11 and the moving block 2 12 to fit together, thereby causing the limiting block 15 to extend further out of the cavity 1 7, so that the limiting block 15 engages with the limiting groove 6, achieving the purpose of fixing the roller 1 and the roller 2 3. Then, the rollers are placed between the logistics transmission tracks, and one end of the rotating shaft 17 is pulled, causing the rotating shaft 17 to extend out of the roller 1 and the roller 2 3 and engage with the inner wall of the logistics transmission track. During this process, the rotating shaft 17 always restricts the locking rod 22, so that the locking rod 22 always retracts into the cavity 2 19 and compresses the spring 21 until the locking groove on the rotating shaft 17 is engaged. The second 23 moves to the locking rod 22, releasing the restraint of the locking rod 22. Under the rebound of the spring 21, it engages with the second 23 of the locking groove, thus fixing the rotating shaft 17 and completing the installation of the roller. When it is necessary to disassemble the roller, simply pull the pull rod 20 along the cavity 19, causing the pull rod 20 to drive the locking rod 22 to separate from the rotating shaft 17 again, releasing the fixing of the rotating shaft 17. Then, retract the rotating shaft 17 to complete the disassembly of the roller. This makes the disassembly and assembly of the roller simple, allowing for quick inspection or assembly of the logistics transmission track. This not only ensures the efficiency of logistics transmission but also reduces unnecessary manpower consumption and completes the operation.

[0035] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
