Description
Technical Field
[0001] This utility model relates to the field of logistics and transportation technology, specifically a safety protection device for logistics and transportation. Background Technology
[0002] With the rapid development of the economy, logistics has become an important part of the production process. Logistics transportation refers to the activities of transporting goods from the origin to the destination using various transportation tools and equipment. It is a core link in the logistics process. In logistics transportation, some bulk goods are packaged in square wooden boxes. To ensure their stability during transportation, protective devices are usually used for protection.
[0003] Existing logistics packaging protection devices have the problem of not being able to adapt to the size of the cargo packaging box. Traditional protection devices often adopt a fixed size design, which makes it difficult to flexibly cope with square cargo packaging boxes of different sizes, resulting in poor protection effect. In addition, traditional protection devices do not provide comprehensive protection for the corners of the packaging box during transportation, and lack special protection measures for the bottom and top corners of the packaging box, thereby reducing the safety of the packaging box in logistics transportation.
[0004] Therefore, there is a need for a safety protection device for logistics transportation to solve the problems of existing protective devices that are not easily adaptable to the size of the cargo packaging box and provide poor protection for the corners of the cargo packaging box. Utility Model Content
[0005] The purpose of this utility model is to provide a safety protection device for logistics transportation, so as to solve the problems of existing protective devices being difficult to adapt to the size of the cargo packaging box and providing poor protection for the corners of the cargo packaging box.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a safety protection device for logistics transportation, including a pallet, a drive mechanism inside the pallet, four circumferentially distributed movable slots on the top surface of the pallet, a lead screw rotatably connected between the two inner side walls of the movable slots, a guide rod fixedly connected between the two inner side walls of the movable slots, a movable block threadedly connected to the outer surface of the lead screw, a first protective angle fixedly connected to the top surface of the movable block, and an adjustment component provided on the top surface of each of the four first protective angles;
[0007] The drive mechanism includes a mounting cavity, which is located at the center of the tray. Four circumferentially distributed rotating shafts are rotatably connected to the bottom surface of the mounting cavity. A driven gear is fastened to the middle of the outer surface of each rotating shaft. A driving bevel gear is coaxially fixedly connected to the top of each rotating shaft. All four driving bevel gears are meshed with driven bevel gears.
[0008] The adjustment assembly includes a sleeve, which is fixedly connected to the top surface of the first protective corner. An extension rod is slidably connected inside the sleeve. A fixing screw hole is provided on one side of the top of the outer surface of the sleeve. Multiple adjustment screw holes that are adapted to the fixing screw holes are evenly provided on the outer surface of the extension rod. The same screw is threaded into the fixing screw hole and one of the adjustment screw holes.
[0009] A servo motor is installed at the center of the bottom surface of the tray. The output end of the servo motor rotates through the inner bottom surface of the mounting cavity and is coaxially fixedly connected to a drive gear. Support feet are fixedly connected at the four corners of the bottom surface of the tray. Anti-collision sleeves are fixedly connected to the outer surface of each sleeve and the outer surface of the extension rod located outside the sleeve. A second protective corner is fixedly connected to the top of each extension rod. One side of the outer wall of each of the four lead screws rotates through the inner side wall of the mounting cavity and is coaxially fixedly connected to four driven bevel gears. All four driven gears are meshed with the drive gear.
[0010] In a preferred embodiment, each of the moving blocks is slidably engaged with a corresponding guide rod, each of the first protective angles is coaxially arranged with a corresponding second protective angle, and the height of the support foot is greater than the height of the servo motor.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. The length of the extension rod extending beyond the sleeve is adjusted by rotating the screw, thereby adjusting the height of the second protective angle. The servo motor drives the drive gear to rotate, which in turn drives the drive bevel gear to rotate, which in turn drives the lead screw to rotate. The four lead screws drive the four first protective angles to move towards the center of the pallet. This method is suitable for goods packaging boxes of different sizes, effectively avoiding the problem that the protective device is not easy to adapt to the size of the goods packaging box.
[0013] 2. By setting the first and second protective corners, the eight outer corners of the cargo packaging box are protected. The anti-collision sleeves further enhance the protection effect of the packaging box, improve the safety of the packaging box in logistics transportation, and thus improve the protection of the goods. This effectively avoids the problem of poor corner protection of the cargo packaging box by the protective device. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example: Figures 1-4 As shown, this utility model provides a technical solution, including a tray 1, a drive mechanism 2 is provided inside the tray 1, four circumferentially distributed movable grooves 3 are opened on the top surface of the tray 1, a lead screw 4 is rotatably connected between the two inner side walls of the movable groove 3, a guide rod 5 is fixedly connected between the two inner side walls of the movable groove 3, a moving block 6 is threadedly connected to the outer surface of the lead screw 4, a first protective angle 7 is fixedly connected to the top surface of the moving block 6, and an adjustment component 8 is provided on the top surface of each of the four first protective angles 7.
[0021] The drive mechanism 2 includes a mounting cavity 21, which is located at the center of the tray 1. Four circumferentially distributed rotating shafts 22 are rotatably connected to the bottom surface of the mounting cavity 21. A driven gear 23 is fastened to the middle of the outer surface of the rotating shaft 22. A driving bevel gear 24 is coaxially fixedly connected to the top of the rotating shaft 22. All four driving bevel gears 24 are meshed with driven bevel gears 25.
[0022] The adjusting component 8 includes a sleeve 81, which is fixedly connected to the top surface of the first protective corner 7. An extension rod 82 is slidably connected inside the sleeve 81. A fixing screw hole 83 is opened on one side of the top surface of the outer surface of the sleeve 81. A plurality of adjusting screw holes 84 that are adapted to the fixing screw holes 83 are evenly opened on the outer surface of the extension rod 82. The same screw 85 is threaded into the fixing screw hole 83 and one of the adjusting screw holes 84.
[0023] A servo motor 9 is installed at the center of the bottom surface of tray 1. The output end of the servo motor 9 rotates through the inner bottom surface of the mounting cavity 21 and is coaxially fixedly connected to a drive gear 10. Support feet 11 are fixedly connected to the four corners of the bottom surface of tray 1. It should be noted that a switch for controlling the start of the servo motor 9 is provided at the front end of tray 1, and a plug for providing power to the servo motor 9 is stored on one side of tray 1. The aforementioned switch and plug are not shown in the attached drawings. The outer surface of each sleeve 81 and the outer surface of the extension rod 82 located outside the sleeve 81 are fixedly connected to... The anti-collision sleeve 12 has a second protective angle 13 fixedly connected to the top of each extension rod 82. The outer wall of one side of each of the four lead screws 4 rotates through the inner side wall of the mounting cavity 21 and is coaxially fixedly connected to the four driven bevel gears 25 respectively. The four driven gears 23 are meshed with the driving gear 10. When the driving gear 10 drives the four driven gears 23 to rotate, the four driven gears 23 drive the four driving bevel gears 24 to rotate synchronously. Through the meshing connection between the driving bevel gears 24 and the driven bevel gears 25, the synchronous rotation of the four lead screws 4 is achieved.
[0024] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that each moving block 6 is slidably engaged with the corresponding guide rod 5 to guide the movement direction of the moving block 6 and improve the stability of the moving block 6 during movement. Each first protective angle 7 is coaxially set with the corresponding second protective angle 13 to ensure that each first protective angle 7 and second protective angle 13 can act on the packaging box. The height of the support foot 11 is greater than the height of the servo motor 9 to avoid direct contact between the servo motor 9 and the ground, thus protecting the servo motor 9.
[0025] In summary: When using this protective device, first place the logistics packaging box at the center of the top surface of the pallet 1. Depending on the height of the packaging box, rotate the screw 85 to disengage it from the sleeve 81 and the extension rod 82, thereby releasing the locking limit on the extension rod 82. Then, push the extension rod 82 upward so that its bottom end gradually slides out of the sleeve 81, thereby adjusting the height of the second protective angle 13. When the second protective angle 13 moves to the same level as the top surface of the packaging box, screw the screw 85 back into the fixing screw hole 83 and the adjusted adjusting screw hole 84 to relock and limit the extension rod 82.
[0026] After adjusting the four second protective angles 13 in sequence, the servo motor 9 is powered on using the plug. The servo motor 9 is turned on by the switch, which drives the drive gear 10 to rotate. Under meshing action, the drive gear 10 drives the four driven gears 23 to rotate simultaneously. The four driven gears 23 drive the four drive bevel gears 24 to rotate synchronously. The four drive bevel gears 24 drive the four driven bevel gears 25 to rotate synchronously, thereby causing the four lead screws 4 to rotate synchronously. Under the action of the threads, the four lead screws 4 drive the four moving blocks 6 to move towards the center of the pallet 1, thereby causing the four first protective angles 7 and the second protective angles 13 to fit against the eight outer corners and outer walls of the packaging box. It has high adjustability and can be used for packaging boxes of different sizes.
[0027] During transportation, the four first protective corners 7 protect the four bottom corners of the packaging box, and the four second protective corners 13 protect the four top corners of the packaging box, improving the safety of the packaging box in logistics transportation and thus enhancing the protection of the goods. At the same time, the anti-collision sleeves 12 further strengthen the protection effect of the packaging box, making the protective device more effective in protecting the packaging box and effectively avoiding the problems that the protective device is not easy to adapt to the size of the packaging box and has poor protection of the corners of the packaging box.
[0028] The servo motor 9 can be purchased from the market and is a mature technology in this field, which has been fully disclosed. Therefore, it will not be described again in the specification.
[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
