Description

Technical Field

[0001] This invention relates to the field of logistics equipment technology, specifically to a stackable logistics equipment designed to prevent collapse. Background Technology

[0002] This logistics equipment is used to secure and fix workpieces during logistics, preventing displacement during transportation and facilitating loading and unloading. Chinese Patent Application No.: CN202310411028.3. Title: A Stackable Anti-Collapse Logistics Equipment. It discloses a panel manufactured using double-sided vacuum forming or blow molding, with a reinforcing bracket encased within the panel to form a panel assembly. The built-in reinforcing bracket helps prevent moisture and rust, extending its service life and preventing operators from being scratched by exposed brackets. The top and bottom surfaces of the panel have inwardly recessed fitting grooves, bonding the upper and lower structural layers together, enhancing the overall integrity of the panel assembly and preventing the internal reinforcing bracket from wobbling. When the logistics equipment is bundled and packaged, the packing grooves limit the strapping, preventing slippage. Due to the structural support of the frame and beams, even with prolonged tight binding of the packing straps, panel collapse and damage can still be effectively prevented.

[0003] While the aforementioned inventions can strengthen the individual structure of logistics equipment, the weight borne by the bottom layer during stacking is often greater, while the pressure decreases towards the top. In existing technology, wooden blocks are placed inside the logistics equipment after stacking to enhance its support. However, this method requires hammering the wooden blocks into the equipment, which can damage the equipment and is time-consuming. Furthermore, during disassembly, the equipment is subjected to significant compressive forces, resulting in substantial clamping forces at the contact points between the equipment and the workpiece. Disassembly by workers requires two workers to lift the cover plate upwards, and another worker must tap the top of the cover plate to vibrate and separate the connection. Moreover, workers cannot distinguish whether the cover plate is clamped to the workpiece, making it unclear whether to lift the cover plate quickly or slowly. Rapidly lifting a clamped cover plate may cause it to break (because the cover plate is intended for repeated use and is made of plastic).

[0004] Therefore, it is necessary to design a stackable, anti-collapse logistics device that will not be damaged during the installation of reinforced support structures, and will not take much time. Furthermore, during disassembly, it should automatically determine whether the workpiece is jammed with the cover plate; if jamming occurs, it should not require three workers to disassemble the cover plate. Summary of the Invention

[0005] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a stackable, anti-collapse logistics device. This device will not be damaged during the installation of reinforced support structures, and the process will not take excessive time. Furthermore, during disassembly, the device can automatically determine whether the workpiece is jammed with the cover plate; if jamming occurs, three workers are not required to disassemble the cover plate.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: The present invention provides a stackable anti-collapse logistics device, including a cover plate, a base support, a bottom plate, and a top plate. The bottom plate is secured to the top of the base support. The bottom plate has multiple recessed grooves for embedding the legs of multiple compressors. Each recessed groove has multiple locking posts at its bottom. The bottom mounting holes of the compressors are secured within the locking posts. The cover plate has multiple sleeves that press against the multiple compressors. The top plate is fixedly installed on the top of the cover plate. The invention is characterized by further including an auxiliary pressing mechanism and... Multiple elastic support mechanisms are provided, and a connecting mechanism is provided between the auxiliary pressing mechanism and the cover plate. The connecting mechanism is used to suspend the auxiliary pressing mechanism at the bottom of the cover plate. When the sleeve is pressed against the top of the compressor, the connecting mechanism is in a retracted state, and the auxiliary pressing mechanism is pressed against the legs of multiple compressors. The top of the base plate has a locking hole for the elastic support mechanism to be inserted, and the cover plate has a T-shaped locking groove for the top of the elastic support mechanism to be inserted. When the base plate is installed between the cover plate and the base plate, one side of the outer edge of the elastic support mechanism abuts against the top of the auxiliary pressing mechanism.

[0007] Preferably, the top of the base plate is provided with two rows of locking holes, each row of locking holes having multiple holes; the bottom of the cover plate is provided with two rows of T-shaped slots, each row of T-shaped slots having multiple slots; the multiple locking holes correspond one-to-one with the multiple T-shaped slots; the top of each elastic support mechanism is locked onto the T-shaped slot; and the bottom of each elastic support mechanism is locked onto the locking hole.

[0008] Preferably, the elastic support mechanism includes a locking plate, a lifting spring, an elastic adjustment mechanism, a sliding sleeve, a locking base, and a sliding column. The top of the sliding column is fixedly connected to the locking plate, the locking plate is locked in the T-shaped slot, the sliding column is slidably connected to the sliding sleeve, the lifting spring is inserted into the sliding sleeve, the top of the lifting spring abuts against the bottom of the sliding column, the bottom of the lifting spring abuts against the elastic adjustment mechanism, the elastic adjustment mechanism is installed in the sliding sleeve, and the elastic adjustment mechanism is used to adjust the elastic force of the lifting spring on the sliding column. The locking base is fixedly installed at the bottom of the sliding sleeve and is inserted into the locking hole.

[0009] Preferably, the outer edge of the sliding sleeve is provided with multiple strip grooves, and the lifting plate can be vertically slidably installed in the strip grooves. The outer edge of the lifting plate is fixedly provided with strip grooves inserted into the strip grooves. The outer edge of the lifting plate is provided with external threads. The screw sleeve is sleeved on the outer edge of the lifting plate and is rotatably connected to the 3D. The inner edge of the screw sleeve is provided with internal threads that connect with the external threads of the lifting plate. The outer edge of the screw sleeve is hexagonal.

[0010] Preferably, the auxiliary pressing mechanism includes multiple crossbars that press against the legs of the compressor. The multiple crossbars are fixedly connected by longitudinal bars. Each crossbar has multiple locking holes, and at least one locking post in each recessed groove engages with the locking hole.

[0011] Preferably, the snap-fit ​​base includes a pin, a mounting base, a pressure plate, and a flip plate. The mounting base is fixedly installed at the bottom of the strip groove, the pressure plate is fixedly installed on the outer edge of the mounting base and presses against the top of the crossbar, and the flip plate is fixedly installed at the end of the pressure plate, with one side of the flip plate fitting against the crossbar.

[0012] Preferably, the connecting mechanism includes four upper hinge rods and four lower hinge rods. The tops of the four upper hinge rods are hinged to the top of the cover plate, one end of each of the four lower hinge rods is hinged to the bottom of the four upper hinge rods, and the bottom of the four lower hinge rods is hinged to the top of the auxiliary pressing mechanism.

[0013] Preferably, an auxiliary support mechanism is fixedly installed on the auxiliary pressing mechanism. The auxiliary support mechanism is used to support the middle part of the cover plate. The auxiliary support mechanism includes a lifting slide rod, a second sliding sleeve, a hinge rod, and a linear pushing mechanism. The second sliding sleeve is fixedly installed on the top of the auxiliary pressing mechanism. The lifting slide rod is slidably connected to the second sliding sleeve. A hinge plate is provided on one side of the lifting slide rod. A vertical sliding groove is opened on the second sliding sleeve for the hinge plate to pass through. One end of the hinge rod is hinged to the hinge plate, and the other end of the hinge rod is hinged to the linear pushing mechanism. The linear pushing mechanism is fixedly installed on the top of the auxiliary pressing mechanism and is used to horizontally push one end of the hinge rod.

[0014] Preferably, the linear push mechanism includes a screw, a screw plate, a baffle, a displacement plate, a guide post, and a guide seat. The screw plate and the guide seat are both fixedly installed on the auxiliary pressing mechanism. The screw is engaged with the screw plate, the displacement plate is engaged with the screw, the guide post is fixedly installed at one end of the screw, the guide post is slidably connected to the guide seat, and the baffle is fixedly installed at the other end of the screw. When the top of the lifting slide bar contacts the bottom of the cover plate, the baffle abuts against one side of the elastic support mechanism.

[0015] The beneficial effects of this invention are as follows: This stackable anti-collapse logistics device compresses the elastic support mechanism and engages its top with a T-shaped slot on the cover plate. After engagement, releasing the elastic support mechanism allows its bottom to engage with a locking hole, thus strengthening the support structure between the cover plate and the base plate. Furthermore, the number of elastic support mechanisms required for structural reinforcement can be determined independently. Compared to the existing method of adding wooden blocks, this structure does not require significantly more time and does not damage the logistics device.

[0016] The top of the top plate is no longer compressed by heavy objects, allowing the elastic support mechanism to push the top plate upwards through elastic force. If the top plate can be pushed upwards, it means that there is no jamming between the sleeve and the compressor. If the top plate cannot be pushed upwards, it means that there is jamming between the two. In this case, workers need to tap the jamming point to separate the top plate upwards. This solves the problem of automatically determining whether there is jamming between the workpiece and the cover plate when disassembling the equipment. If jamming occurs, it is not necessary for three workers to disassemble the cover plate.

[0017] When the elastic support mechanism is engaged between the cover plate and the base plate, rotating the elastic force adjustment mechanism compresses the lifting spring upwards, increasing the elastic force exerted by the lifting spring on the sliding column and thus strengthening the support. This allows workers to reduce the number of elastic support mechanisms needed by adjusting the elastic force through the elastic force adjustment mechanism when it is not possible to add more.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example: This invention provides a stackable, anti-collapse logistics device, such as... Figure 1-4As shown, the system includes a cover plate 1, a base support 10, a bottom plate 11, and a top plate 12. The bottom plate 11 is fitted onto the top of the base support 10. The bottom plate 11 has multiple recessed grooves for embedding the legs of multiple compressors 2. Each recessed groove has multiple locking posts 11a at its bottom. The bottom mounting holes of the compressors 2 are fitted into the locking posts 11a. The cover plate 1 has multiple sleeves 1a, which are pressed onto the multiple compressors 2 respectively. The top plate 12 is fixedly installed on the top of the cover plate 1. The system also includes an auxiliary pressing mechanism 4 and multiple elastic support mechanisms 3. A connecting mechanism 5 is provided between the auxiliary pressing mechanism 4 and the cover plate 1. The connecting mechanism 5 is used to... The auxiliary pressing mechanism 4 is suspended at the bottom of the cover plate 1. When the sleeve 1a is pressed against the top of the compressor 2, the connecting mechanism 5 is in a retracted state, and the auxiliary pressing mechanism 4 presses against the legs of the multiple compressors 2. The top of the base plate 11 has a locking hole 11b for the insertion of the elastic support mechanism 3, and the cover plate 1 has a T-shaped locking groove 1b for the top of the elastic support mechanism 3 to be inserted. When the base plate 11 is installed between the cover plate 1 and the base plate 11, one side of the outer edge of the elastic support mechanism 3 abuts against the top of the auxiliary pressing mechanism 4, thus fixing the auxiliary pressing mechanism 4 and enabling it to press against the legs of the compressors 2. First, the auxiliary pressing mechanism 4 is inserted into the locking posts 11a on the multiple base plates 11. Then, multiple logistics devices are stacked, and after stacking, the multiple logistics devices are tied together with straps. Finally, the elastic support mechanism 3 is installed. When installing the elastic support mechanism 3, it is first compressed, and then its top is engaged with the T-shaped slot 1b on the cover plate 1. After engagement, the elastic support mechanism 3 is released, causing its bottom to engage with the slot 11b, thus strengthening the support structure between the cover plate 1 and the base plate 11. The number of elastic support mechanisms 3 required can be determined based on the structural reinforcement needs. Compared to the existing method of adding wooden blocks, this structure does not take much time and will not damage the logistics equipment.

[0034] When the logistics equipment needs to be disassembled, since the top of the top plate 12 is no longer compressed by heavy objects, the elastic support mechanism 3 can push the top plate 12 upward through elastic force. If the top plate 12 can be pushed upward, it means that there is no jamming between the sleeve 1a and the compressor 2. If the top plate 12 cannot be pushed upward, it means that there is jamming between the two. In this case, workers need to tap the jamming point so that the top plate 12 can be separated upward. This solves the problem of automatically judging whether there is jamming between the workpiece and the cover plate when disassembling the equipment. If there is jamming, three workers are not needed to disassemble the cover plate.

[0035] The key structure for separating the sleeve 1a from the top of the compressor 2 is that when the elastic support mechanism 3 lifts the sleeve 1a upward, the elastic support mechanism 3 presses the compressor 2 onto the base plate 11 through the auxiliary pressing mechanism 4, so as to prevent the sleeve 1a from pulling the compressor 2 upward, thus realizing the separation between the sleeve 1a and the compressor 2.

[0036] During the separation process, the sleeve 1a can be vibrated by tapping the side of the cover plate 1. Initially, a wooden stick is used for tapping, followed by an iron stick, in order to protect the outer periphery of the cover plate 1 from damage.

[0037] In order to enable the installation of a corresponding number of flexible support mechanisms 3 as needed, therefore, as follows Figure 3 and Figure 4 As shown, the top of the base plate 11 has two rows of locking holes 11b, with multiple locking holes in each row. The bottom of the cover plate 1 has two rows of T-shaped slots 1b, with multiple slots in each row. The multiple locking holes 11b correspond one-to-one with the multiple T-shaped slots 1b. The top of each elastic support mechanism 3 is locked onto the T-shaped slot 1b, and the bottom of each elastic support mechanism 3 is locked onto the locking hole 11b. By setting multiple locking holes 11b and multiple T-shaped slots 1b, multiple elastic support mechanisms 3 can be set as needed. When no elastic support mechanism 3 is needed, the locking holes 11b and T-shaped slots 1b can be left unused.

[0038] If the elastic support mechanism 3 is fixed by workers using tools to squeeze it between the cover plate 1 and the base plate 11, and then releasing it, the process is too cumbersome. Workers could be injured by the elastic force of the mechanism if they are not careful. Furthermore, if the elastic force of the elastic support mechanism 3 is constant, changing the number of mechanisms to alter the support force would require a large number of underlying elastic support mechanisms 3. Figure 5 and Figure 6As shown, the elastic support mechanism 3 includes a locking plate 3a, a lifting spring 3b, an elastic adjustment mechanism 3c, a sliding sleeve 3d, a locking base 3e, and a sliding column 3f. The top of the sliding column 3f is fixedly connected to the locking plate 3a. The locking plate 3a is locked in the T-shaped slot 1b. The connection between the top of the elastic support mechanism 3 and the cover plate 1 is achieved by locking the locking plate 3a and the cover plate 1. The sliding column 3f is slidably connected to the sliding sleeve 3d. The lifting spring 3b is inserted into the sliding sleeve 3d. The top of the lifting spring 3b... The bottom of the lifting spring 3b abuts against the bottom of the sliding column 3f, and the bottom of the lifting spring 3b abuts against the elastic adjustment mechanism 3c. The elastic adjustment mechanism 3c is installed inside the sliding sleeve 3d and is used to adjust the elastic force of the lifting spring 3b on the sliding column 3f. When the elastic support mechanism 3 is engaged between the cover plate 1 and the base plate 11, rotating the elastic adjustment mechanism 3c compresses the lifting spring 3b upward, thereby increasing the elastic force applied by the lifting spring 3b to the sliding column 3f and strengthening the support force. This allows workers to adjust the elastic force by adjusting the elastic adjustment mechanism 3c when it is not possible to add more elastic support mechanisms 3, thus reducing the number of elastic support mechanisms 3. The snap-fit ​​base 3e is fixedly installed at the bottom of the sliding sleeve 3d and is inserted into the snap-fit ​​hole 11b. Instead of snapping, the base 3e is inserted into the base plate 11, allowing the elastic support mechanism 3 to be removed when the cover plate 1 is lifted. This enables workers to remove the compressor 2 more quickly. Furthermore, the elastic support mechanism 3 supports the bottom of the cover plate 1 when it is placed, preventing the sleeve 1a from contacting and wearing with the ground.

[0039] In order to compress the lifting spring 3b, as Figure 6 and Figure 7 As shown, the outer edge of the sliding sleeve 3d has multiple strip grooves 3d1. The lifting plate 3c1 is vertically slidably installed in the strip grooves 3d1. The outer edge of the lifting plate 3c1 has strip grooves inserted into the strip grooves 3d1. The outer edge of the lifting plate 3c1 has external threads. A threaded sleeve 3c2 is fitted onto the outer edge of the lifting plate 3c1 and is rotatably connected to 3d. The inner edge of the threaded sleeve 3c2 has internal threads that connect with the external threads of the lifting plate 3c1. The outer edge of the threaded sleeve 3c2 is hexagonal. By rotating the threaded sleeve 3c2, it can engage and push the lifting plate 3c1 to verify the vertical sliding of the strip grooves 3d1. When the lifting plate 3c1 slides vertically upwards, it applies an upward compressive force to the lifting spring 3b. Since the sliding column 3f cannot be pushed further upwards, the lifting spring 3b is compressed.

[0040] like Figure 8As shown, the auxiliary pressing mechanism 4 includes multiple crossbars 4b, which press against the legs of the compressor 2. The multiple crossbars 4b can press and fix the multiple compressors 2 to prevent the compressors 2 from sliding upward. The multiple crossbars 4b are fixedly connected by longitudinal bars 4c. Each crossbar 4b has multiple locking holes 4a. In each recessed groove, at least one locking post 11a engages with the locking hole 4a. The auxiliary pressing mechanism 4 engages with the locking post 11a to limit the position of the auxiliary pressing mechanism 4, preventing the auxiliary pressing mechanism 4 from swaying left and right during transportation, and also providing a better pressing effect on the legs of the compressor 2.

[0041] like Figure 10 As shown, the snap-fit ​​base 3e includes a pin 3e1, a mounting base 3e2, a pressure plate 3e3, and a flip plate 3e4. The mounting base 3e2 is fixedly installed at the bottom of the strip groove 3d1, the pressure plate 3e3 is fixedly installed on the outer edge of the mounting base 3e2, and the pressure plate 3e3 presses against the top of the crossbar 4b. The flip plate 3e4 is fixedly installed at the end of the pressure plate 3e3, and one side of the flip plate 3e4 is in contact with the crossbar 4b. When the elastic support mechanism 3 is installed on the top of the base plate 11, the pressure plate 3e3 can press and fix the crossbar 4b, thus fixing the auxiliary pressing mechanism 4. Because the flip plate 3e4 contacts the crossbar 4b, the mounting base 3e2 will not rotate when the elastic support mechanism 3 rotates, thus preventing the crossbar 4b from rotating. Rotation of the mounting base 3e2 can vertically push the lifting plate 3c1 upward. Furthermore, the pressure plate 3e3 and the flip plate 3e4 also serve as rotation indicators, allowing workers to know which direction to rotate.

[0042] like Figure 9 As shown, the connecting mechanism 5 includes four upper hinge rods 5a and four lower hinge rods 5b. The tops of the four upper hinge rods 5a are hinged to the top of the cover plate 1, one end of each of the four lower hinge rods 5b is hinged to the bottom of the four upper hinge rods 5a, and the bottom of each of the four lower hinge rods 5b is hinged to the top of the auxiliary pressing mechanism 4. By setting the four upper hinge rods 5a and the lower hinge rods 5b, the auxiliary pressing mechanism 4 can be suspended. After the auxiliary pressing mechanism 4 contacts the top of the base plate 11, the upper hinge rods 5a and the lower hinge rods 5b will be in contact. Figure 9 The bending state is shown. The auxiliary pressing mechanism 4 is engaged with the locking post 11a to prevent the auxiliary pressing mechanism 4 from wobbling laterally.

[0043] In order to increase the support for the middle part of the cover plate 1, therefore, as Figure 11As shown, an auxiliary support mechanism 7 is fixedly installed on the auxiliary pressing mechanism 4. The auxiliary support mechanism 7 is used to support the middle part of the cover plate 1. The auxiliary support mechanism 7 includes a lifting slide rod 7a, a sliding sleeve 7b, a hinge rod 7c, and a linear pushing mechanism 7d. The sliding sleeve 7b is fixedly installed on the top of the auxiliary pressing mechanism 4. The lifting slide rod 7a is slidably connected to the sliding sleeve 7b. A hinge plate is provided on one side of the lifting slide rod 7a. A vertical sliding groove for the hinge plate to pass through is opened on the sliding sleeve 7b. The hinge rod 7c... One end of the hinge rod 7c is hinged to the hinge plate, and the other end of the hinge rod 7c is hinged to the linear push mechanism 7d. The linear push mechanism 7d is fixedly installed on the top of the auxiliary pressing mechanism 4. The linear push mechanism 7d is used to horizontally push one end of the hinge rod 7c. After the linear push mechanism 7d pushes one end of the hinge rod 7c to move, the hinge rod 7c pushes the hinge plate upward to slide the lifting slide rod 7a vertically, so that the top of the lifting slide rod 7a contacts the bottom of the cover plate 1, thereby achieving support for the cover plate 1.

[0044] To prevent the linear drive mechanism 7d from loosening due to vibration during transportation, such as... Figure 12 As shown, the linear push mechanism 7d includes a screw 7d1, a screw plate 7d2, a baffle 7d3, a displacement plate 7d4, a guide post 7d5, and a guide seat 7d6. The screw plate 7d2 and guide seat 7d6 are both fixedly mounted on the auxiliary pressing mechanism 4. The screw 7d1 is meshed with the screw plate 7d2, and the displacement plate 7d4 is meshed with the screw 7d1. The guide post 7d5 is fixedly mounted on one end of the screw 7d1 and slidably connected to the guide seat 7d6. The baffle 7d3 is fixedly mounted on the other end of the screw 7d1. When the top of the lifting slide rod 7a contacts the bottom of the cover plate 1, the baffle 7d3 abuts against one side of the elastic support mechanism 3. By rotating the baffle 7d3, the displacement plate 7d4 can push the hinge rod 7c to move horizontally, thereby vertically lifting the clamping plate 3a. After the above installation is completed, the elastic support mechanism 3 is inserted between the cover plate 1 and the base plate 11, so that the elastic support mechanism 3 limits the baffle 7d3 and prevents the baffle 7d3 from moving backward during transportation. Alternatively, as needed, a number of auxiliary support mechanisms 7 can be set, and the positions of multiple auxiliary support mechanisms 7 can all be blocked by the elastic support mechanism 3.

[0045] In use, the compressor 2 is inserted into the bottom plate 11, and then the cover plate 1 and the top plate 12 are placed on top of the multiple compressors 2. Then, the multiple logistics devices are stacked and then tied together. Depending on the height of each layer of logistics devices, a different number of elastic support mechanisms 3 are installed. If the number of elastic support mechanisms 3 cannot be increased, the support force can be strengthened by adjusting the support elasticity of the elastic support mechanisms 3.

[0046] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
