Description

Technical Field

[0001] This utility model relates to the field of modular wooden crates, and more specifically, to stackable modular wooden crates that can avoid displacement due to bumps. Background Technology

[0002] In the logistics, transportation and warehousing sector, stackable wooden crates are widely used due to their ability to make full use of space and facilitate bulk transportation.

[0003] Traditional stackable wooden crates have certain drawbacks. During transportation, uneven road surfaces, sudden braking, and turning can cause horizontal sliding and vertical displacement of the crates between layers. This can lead to collisions and crushing damage to goods, and in severe cases, it can cause the stack to collapse, creating safety hazards. At the same time, traditional wooden crates lack flexibility in movement. If ease of movement is prioritized, they are prone to shaking when stacked, which reduces logistics turnover efficiency to some extent and makes it difficult to meet the high-efficiency requirements of modern logistics.

[0004] Therefore, it is necessary to redesign a stackable modular wooden crate to avoid the above problems and prevent it from shifting due to bumps. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, embodiments of the present invention provide stackable modular wooden crates that can avoid displacement due to bumps.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A stackable modular wooden crate designed to prevent shifting due to bumps includes a base and a crate body, with the crate body fixedly mounted on the upper surface of the base. Multiple support columns are symmetrically fixedly mounted on the bottom of the base. Each support column has a fixed groove at its bottom end, and a moving device is installed within each fixed groove. A sliding groove is provided on one side of each support column, and an installation groove and a locking groove are respectively provided on the inner walls of both sides of each sliding groove. A limiting device is provided within each installation groove, with the output end of the limiting device abutting against the output end of the moving device, and the output end of the limiting device connecting to the corresponding locking groove. Multiple limiting grooves are symmetrically provided on the bottom of the base.

[0007] In a preferred embodiment, each of the moving devices includes a second spring, which is fixedly installed on the inner top wall of the fixed groove. A connecting rod is fixedly installed at one end of the second spring and is slidably connected in the fixed groove. A connecting block is fixedly installed on the outer wall of the connecting rod and is slidably connected in the groove. The output end of the moving device abuts against the upper end face of the connecting block. A rotating ball is rotatably installed at the bottom end of the connecting rod.

[0008] In a preferred embodiment, the limiting device includes a first spring, which is fixedly connected to the inner wall of the mounting groove. A blocking block is fixedly installed at one end of the first spring and is slidably connected in the mounting groove. One end of the blocking block is inserted into a corresponding slot, and the bottom end of the blocking block abuts against the upper surface of the connecting block. A movable block is fixedly installed on one side of the blocking block.

[0009] In a preferred embodiment, each of the support columns has a movable groove on one side, and a movable block is slidably connected in the movable groove.

[0010] In a preferred embodiment, a plurality of second locking blocks are fixedly installed at equal intervals on the inner top wall of each of the limiting grooves.

[0011] In a preferred embodiment, the upper end face of the box is provided with a cover plate, and a plurality of limiting blocks are symmetrically and fixedly installed on the upper end face of the cover plate, and the positions of the plurality of limiting blocks correspond to the positions of the plurality of limiting grooves respectively. A plurality of first locking teeth are fixedly installed at equal intervals on the upper end face of each limiting block.

[0012] In a preferred embodiment, a rubber pad is fixedly installed at the bottom end of each of the support columns.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up limiting grooves, limiting blocks, first locking teeth, second locking blocks and other devices, effectively prevents the wooden box from sliding horizontally and shifting vertically during transportation by setting up limiting grooves, limiting blocks and limiting blocks of the upper and lower box bodies nesting together, first locking teeth and second locking blocks engaging, and limiting devices of the support columns limiting the movement of the moving device. This reduces the possibility of damage to goods due to box shaking.

[0014] 2. This utility model incorporates a moving device and a limiting device. The rotating ball in the moving device allows the wooden crates to move flexibly when placed and adjusted, saving labor costs. The limiting device can lock the moving parts when needed, ensuring that the rotating ball does not extend or retract arbitrarily during stacking. Combined with the nested structure of the upper and lower layers, the stacking state is stable and firm. This not only facilitates the handling of individual crates but also ensures the safety of multi-layer stacking, thus helping to improve the overall logistics turnover efficiency.

[0015] In summary, this utility model is simple to operate. By nesting the upper and lower limiting blocks and limiting grooves, engaging the first locking tooth and the second locking block, and limiting the moving device on the support column, it effectively prevents horizontal sliding and vertical displacement during transportation bumps, reducing the possibility of damage to goods due to shaking. The rotating ball of the moving device facilitates the flexible movement of wooden boxes, saving manpower. The limiting device can lock the moving parts, ensuring that the rotating ball does not extend or retract arbitrarily when stacked. Combined with the nesting structure, it makes the stacking stable, which is convenient for individual handling and ensures the safety of multi-layer stacking. Attached Figure Description

[0018] 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.

[0019] Reference Figure 1-5The stackable combination wooden crate, which can avoid bumps and displacement, includes a base 1 and a box body 2. The box body 2 is fixedly installed on the upper surface of the base 1. Multiple support columns 8 are symmetrically fixedly installed on the bottom end of the base 1. The symmetrical distribution of the support columns 8 makes the wooden crate more stable, distributes the weight of the box body, avoids excessive force on a single point and deformation, and provides a mounting carrier for the moving device and the limiting device.

[0020] Each support column 8 has a fixed groove 18 at its bottom end, and a moving device is provided in each fixed groove 18. Each support column 8 has a sliding groove 14 on one side, and an installation groove 15 and a locking groove 16 are respectively provided on the inner walls of both sides of each sliding groove 14. Each installation groove 15 is provided with a limiting device, and the output end of the limiting device abuts against the output end of the moving device. The output end of the limiting device is connected to the locking groove 16 with the corresponding position. Multiple limiting grooves 6 are symmetrically provided at the bottom end of the base 1.

[0021] Each moving device includes a second spring 17, which is fixedly installed on the inner top wall of the fixing groove 18. A connecting rod 19 is fixedly installed on one end of the second spring 17 and is slidably connected in the fixing groove 18. A connecting block 13 is fixedly installed on the outer wall of the connecting rod 19 and is slidably connected in the slide groove 14. The output end of the moving device abuts against the upper end face of the connecting block 13. A rotating ball 20 is rotatably installed on the bottom end of the connecting rod 19. The rotating ball 20 reduces the friction between the wooden box and the contact surface when the box moves, making it easier to adjust the position flexibly.

[0022] The limiting device includes a first spring 10, which is fixedly connected to the inner wall of the mounting groove 15. A blocking block 12 is fixedly installed at one end of the first spring 10, and the blocking block 12 is slidably connected in the mounting groove 15. One end of the blocking block 12 is inserted into the corresponding slot 16, and the bottom end of the blocking block 12 abuts against the upper end face of the connecting block 13. A movable block 11 is fixedly installed on one side of the blocking block 12. A movable slot 9 is opened on one side of each support column 8, and the movable block 11 is slidably connected in the movable slot 9. The movable block 11 facilitates manual operation of the blocking block 12 and flexibly switches the limiting state.

[0023] Multiple second locking blocks 7 are fixedly installed at equal intervals on the inner top wall of each limiting groove 6. A cover plate 3 is provided on the upper end face of the box body 2. Multiple limiting blocks 4 are fixedly installed symmetrically on the upper end face of the cover plate 3, and the positions of the multiple limiting blocks 4 correspond to the positions of the multiple limiting grooves 6. Multiple first locking teeth 5 are fixedly installed at equal intervals on the upper end face of each limiting block 4. The nesting of the limiting blocks 4 and the limiting grooves 6 realizes the initial positioning of the upper and lower wooden boxes. The engagement of the first locking teeth 5 and the second locking blocks 7 further enhances the tightness of the connection, effectively preventing horizontal sliding and vertical displacement, reducing the risk of damage to goods. At the same time, the operator can more conveniently lift the box body 2 through the limiting grooves 6.

[0024] Each support column 8 has a rubber pad 21 fixedly installed at its bottom end to increase the friction between the support column 8 and the contact surface, reduce the sliding of the wooden box, and also play a role in cushioning and shock absorption, further improving the anti-bump performance.

[0025] In use, the core of this invention is the nesting and positioning of the upper and lower boxes. Multiple symmetrically positioned grooves 6 on the bottom of the lower wooden box base 1 correspond one-to-one with multiple positioning blocks 4 on the upper surface of the upper wooden box cover 3. When stacked, the positioning blocks 4 of the upper wooden box embed into the positioning grooves 6 of the lower wooden box, forming initial horizontal positioning. Simultaneously, multiple second locking blocks 7 on the top wall of the positioning groove 6 engage with multiple first locking teeth 5 on the upper surface of the positioning blocks 4, further enhancing the tightness of the connection between the upper and lower layers and effectively preventing relative horizontal sliding. Secondly, the limiting device precisely restricts the movement range of the moving device, further ensuring the stability of the wooden box. One end of the first spring 10 in the mounting groove 15 is connected to the blocking block 12. In its natural state, the elastic force of the first spring 10 will push the blocking block 12, so that one end of it is inserted into the slot 16, while the bottom end of the blocking block 12 abuts against the upper end face of the connecting block 13. When the moving device is needed, this opposing state can effectively prevent the rotating ball 20 from retracting into the fixed groove 18 under the elastic action of the second spring 17, ensuring that the rotating ball 20 can normally play the function of assisting movement and fine adjustment. When stacking, the moving block 11 slides in the moving groove 9, driving the blocking block 12 to compress the first spring 10 and disengage it from the slot 16. At this time, the connecting block 13 can move freely. After the adjustment is completed, the moving block 11 is released, and the blocking block 12 re-enters the slot 16 under the action of the first spring 10, realizing the limit again. The limiting device also limits the moving device through the cooperation of the blocking block 12 and the connecting block 13, preventing the rotating ball 20 from moving out of the fixed groove 18 and ensuring the structural stability of the support column 8. Finally, the rubber pad 21 fixedly installed at the bottom of the support column 8 can increase the friction between the support and the contact surface, reduce the sliding of the wooden box on the plane, and also play a certain role in buffering and shock absorption, further improving the overall anti-bump performance.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
