Description

Technical Field

[0001] This utility model belongs to the technical field of metal opening mesh cover, and particularly relates to high-strength metal opening mesh cover. Background Technology

[0002] In the field of warehousing and logistics and cargo storage, racks are commonly used equipment for carrying and placing goods. In order to achieve orderly management of goods and avoid confusion between different types or specifications of goods, it is usually necessary to set up partition structures inside the racks to classify and isolate the goods. Metal mesh covers have become a common choice for rack partitions due to their good air permeability, visibility and certain structural stability.

[0003] However, existing metal mesh covers are mostly connected to the shelves by direct fixed installation, resulting in a fixed spacing between two adjacent metal mesh partitions. This makes it impossible to flexibly adjust the spacing according to changes in the size and quantity of stored goods. When storing large items, the fixed spacing of the mesh covers can become an obstacle. Most existing metal mesh covers adopt a single-layer metal mesh structure design. In order to control production costs and reduce the overall weight of the mesh cover, the thickness of the single-layer metal mesh and the diameter of the mesh wires are usually small, resulting in low overall structural strength of the mesh cover. During warehousing operations, goods are prone to collision with the mesh cover during handling, and the mesh cover is very prone to local deformation, dents, or even mesh wire breakage. This not only affects the appearance and service life of the mesh cover, but also causes other problems. Therefore, we propose a high-strength metal open mesh cover. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength metal open mesh cover to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a high-strength metal open mesh cover, comprising:

[0006] A rectangular frame is provided, in which two metal meshes are fixedly installed, and several connecting rods are fixedly installed between the two metal meshes. A lifting rod is provided at the top of the rectangular frame, and a rubber pad is fixedly installed at the top of the lifting rod. A rubber pad is fixedly installed at the bottom of the rectangular frame. Two movable slots are opened at the top of the rectangular frame, and sliding blocks are slidably installed in the movable slots. Support rods are rotatably installed at the top of the sliding blocks. Two through slots are opened at the bottom of the lifting rod, and the tops of the two support rods extend into the two through slots respectively.

[0007] A driving component, located within a rectangular frame, is used to drive two sliding blocks to move closer or further apart.

[0008] Two slots are symmetrically opened on one side of the rectangular frame, and plugs are symmetrically fixedly installed on the other side of the rectangular frame;

[0009] A limiting component, which is located within a rectangular frame and is used to limit the rectangular frame.

[0010] In this technical solution, during use, personnel can place the entire device in a suitable position on the shelf. Then, the drive assembly moves two sliding blocks, which in turn press against the support rod, causing it to rotate. Simultaneously, the top of the support rod rotates within the through slot. This rotation of the two support rods lifts the lifting rod, causing it to move upwards until the rubber pad at the top of the lifting rod touches the shelf. At this point, both rubber pads deform. Under the pressure of the lifting rod and the friction between the rubber pads, the rectangular frame... Fixed in a suitable position on the shelf, the rectangular frames can be easily fixed in any position on the shelf by personnel. The installation position of the rectangular frames on the shelf can be disassembled and adjusted at any time according to the actual size and quantity requirements of the goods, thereby flexibly changing the spacing between adjacent rectangular frames. When storing large-volume goods, the number of rectangular frames can be reduced or the spacing can be increased to avoid obstruction; when storing small-volume goods, the number of rectangular frames can be increased or the spacing can be reduced to achieve classified storage, effectively avoiding waste of shelf space, significantly improving the adaptability and utilization of warehouse space, and eliminating the need for repeated disassembly and reassembly of rectangular frames, reducing the tedium of operation.

[0011] When the metal mesh is impacted, the presence of two metal meshes connected by several connecting rods gives the mesh high strength. Upon impact, the two meshes can share the impact force, thereby reducing the probability of damage and significantly improving the overall structural strength and impact resistance of the metal mesh. During cargo handling, even if the metal mesh is hit by a collision or lateral pressure is generated by stacked goods, the multi-mesh combination structure can disperse the force, effectively preventing local deformation, dents, or wire breakage of the metal mesh, thus ensuring the integrity of the metal mesh's appearance and its service life.

[0012] When the entire device is not in use, personnel can insert the two inserts on one of the rectangular frames from top to bottom into the two slots on the other rectangular frame until the inserts are fully inserted into the slots. The limiting component can then fix the two rectangular frames together. Through this operation, multiple rectangular frames can be combined together for storage and transportation, significantly reducing the storage space occupied by a single rectangular frame, avoiding damage to the rectangular frames caused by stacking and squeezing, and reducing the risk of damage to the rectangular frames caused by collisions and squeezing during transportation. This reduces the overall cost of using the device from both storage and transportation perspectives and improves the management convenience of warehousing auxiliary equipment.

[0013] In the above technical solution, the driving component further includes:

[0014] Two threaded rods are rotatably installed in two movable slots. One end of each threaded rod passes through two sliding blocks. The other end of one of the threaded rods passes through one side of the movable slot, extends to the outside, and is fixedly fitted with a knob.

[0015] In this technical solution, rotating the knob causes two threaded rods to rotate. Under the action of the threads, the rotation of the two threaded rods drives two sliding blocks to move. The movement of the sliding blocks compresses the support rod, causing it to rotate on the sliding blocks. Simultaneously, the top of the support rod rotates within the through groove. The rotation of the two support rods lifts the lifting rod, causing it to move upwards until the rubber pad at the top of the lifting rod touches the shelf. At this point, both rubber pads deform. Under the pressure of the lifting rod and the friction between rubber pads, the shelf is lifted... The rectangular frames are fixed in suitable positions on the shelves, ensuring that personnel can easily fix the frames in any position on the shelves. Personnel can disassemble and adjust the installation position of the rectangular frames on the shelves at any time according to the actual size and quantity requirements of the goods, thereby flexibly changing the spacing between adjacent rectangular frames. When storing large-volume goods, the number of rectangular frames can be reduced or the spacing can be increased to avoid obstruction; when storing small-volume goods, the number of rectangular frames can be increased or the spacing can be reduced to achieve classified storage, effectively avoiding waste of shelf space, significantly improving the adaptability and utilization of warehouse space, and eliminating the need for repeated disassembly and reassembly of rectangular frames, reducing the tedium of operations.

[0016] In the above technical solution, the two threaded rods are coaxially connected, the threaded rods are rotatably connected to the rectangular frame, and the sliding block is threadedly connected to the threaded rods.

[0017] In this technical solution, it is ensured that the two threaded rods can rotate simultaneously, that the threaded rods can rotate normally within the rectangular frame, and that the rotation of the threaded rods can drive the sliding block to move.

[0018] In the above technical solution, the limiting component further includes:

[0019] A sliding groove is formed within a rectangular frame and located below one of the slots. A limiting block is slidably installed within the sliding groove. One end of the limiting block passes through one side of the sliding groove and extends to the outside. The other end of the limiting block is fixedly installed with a spring that is fixed to the inner wall of the sliding groove. One side of the limiting block passes through the sliding groove and is fixedly installed with a pressing plate. A limiting hole is formed on the other side of the rectangular frame and on one side of the sliding groove.

[0020] In this technical solution, when the entire device is not in use, personnel can insert two blocks from one rectangular frame into two slots on another rectangular frame from top to bottom. Simultaneously, one rectangular frame will press against a limiting block on the other rectangular frame, causing the limiting block to move and compress a spring until the blocks are fully inserted into the slots. At this point, under the action of the spring's rebound force, the spring will compress the limiting block to reset, causing one end of the limiting block to insert into the corresponding limiting hole, thereby fixing the two rectangular frames together. Through the above operation, multiple rectangular frames can be combined together for storage and transportation, significantly reducing the storage space occupied by a single rectangular frame, avoiding damage to the rectangular frames caused by stacking and compression, and reducing the risk of damage to the rectangular frames due to collisions and compression during transportation. This reduces the overall operating cost of the device from both storage and transportation perspectives and improves the management convenience of the warehousing auxiliary equipment.

[0021] In the above technical solution, one end of the limiting block is inclined, and one end of the limiting block is inserted into the limiting hole.

[0022] In this technical solution, it is ensured that the downward movement of the other rectangular frame can squeeze the limiting block to move, and that one end of the limiting block can be inserted into the limiting hole.

[0023] In the above technical solution, the top end of the support rod is rotatably connected to the through groove, the support rod has an inclined structure, and the support rod is movably connected to the movable groove and the through groove.

[0024] In this technical solution, it is ensured that the top of the support rod can rotate normally within the through groove, thus ensuring the structural stability of the support rod and allowing it to rotate and move within the movable groove and the through groove.

[0025] In the above technical solution, the insert block is further configured to engage with the slot, and the slot has a T-shaped cross-section.

[0026] In this technical solution, it is ensured that the plug can be inserted into the slot and that the plug will not fall out of the slot.

[0027] The beneficial effects of this utility model are:

[0028] 1. This high-strength metal open mesh cover allows personnel to disassemble and adjust the installation position of the rectangular frames on the shelf at any time according to the actual size and quantity requirements of the goods. This enables flexible changes in the spacing between adjacent rectangular frames. When storing larger goods, the number of rectangular frames can be reduced or the spacing increased to avoid obstruction; when storing smaller goods, the number of rectangular frames can be increased or the spacing reduced to achieve classified storage. This effectively avoids wasting shelf space, significantly improves the adaptability and utilization of warehouse space, and eliminates the need for repeated disassembly and reassembly of rectangular frames, reducing operational complexity.

[0029] 2. This high-strength metal open mesh cover can distribute the force even if the metal mesh is hit during cargo handling or if the stacked goods generate lateral pressure. This effectively prevents the metal mesh from being deformed, dented, or broken, thus ensuring the integrity of the metal mesh's appearance and its service life.

[0030] 3. This high-strength metal open mesh cover can combine multiple rectangular frames together for storage and transportation through the above operations, which greatly reduces the storage space occupied by a single rectangular frame, avoids damage to the rectangular frames caused by stacking and squeezing, and reduces the risk of damage to the rectangular frames caused by collisions and squeezing during transportation. It reduces the overall cost of using the device from both storage and transportation perspectives and improves the management convenience of warehousing auxiliary equipment.

[0047] Example 1:

[0048] Please see Figure 1 - Figure 9 As shown, this embodiment provides a high-strength metal opening mesh cover, including:

[0049] A rectangular frame 1 has two metal meshes 2 fixedly installed inside it. Several connecting rods 3 are fixedly installed between the two metal meshes 2. A lifting rod 4 is provided at the top of the rectangular frame 1. A rubber pad 5 is fixedly installed at the top of the lifting rod 4. A rubber pad 6 is fixedly installed at the bottom of the rectangular frame 1. Two movable slots 7 are opened at the top of the rectangular frame 1. A sliding block 8 is slidably installed in the movable slot 7. A support rod 9 is rotatably installed at the top of the sliding block 8. Two through slots 10 are opened at the bottom of the lifting rod 4. The tops of the two support rods 9 extend into the two through slots 10 respectively.

[0052] A limiting component is located within rectangle 1 and is used to limit rectangle 1.

[0053] In operation, the entire device can be placed in a suitable position on the shelf. The drive assembly then moves the two sliding blocks 8. The movement of the sliding blocks 8 compresses the support rod 9, causing it to rotate. Simultaneously, the top of the support rod 9 rotates within the through groove 10. This rotation of the two support rods 9 lifts the lifting rod 4, causing it to move upwards until the rubber pad 5 at the top of the lifting rod 4 touches the shelf. At this point, both rubber pads 5 and 6 deform. Under the pressure of the lifting rod 4 and the friction between the rubber pads 5 and 6, the device can... Rectangular frame 1 is fixed in a suitable position on the shelf, ensuring that personnel can easily fix rectangular frame 1 in any position on the shelf. Personnel can disassemble and adjust the installation position of rectangular frame 1 on the shelf at any time according to the actual size and quantity requirements of the goods, thereby flexibly changing the spacing between adjacent rectangular frames 1. When storing large-volume goods, the number of rectangular frames 1 can be reduced or the spacing can be increased to avoid obstruction; when storing small-volume goods, the number of rectangular frames 1 can be increased or the spacing can be reduced to achieve classified storage, effectively avoiding waste of shelf space, significantly improving the adaptability and utilization of warehouse space, and eliminating the need for repeated disassembly and reassembly of rectangular frames 1, reducing the tedium of operations.

[0054] When the metal mesh 2 is impacted, the presence of two metal meshes 2 connected by several connecting rods 3 gives the metal mesh 2 high strength. Upon impact, the two metal meshes 2 can share the impact force, thereby reducing the probability of damage to the metal mesh 2 and significantly improving the overall structural strength and impact resistance of the metal mesh 2. During cargo handling, even if the metal mesh 2 is collided or lateral pressure is generated by the stacking of goods, the multi-metal mesh 2 combination structure can disperse the force, effectively preventing the metal mesh 2 from undergoing local deformation, dents, or wire breakage, thus ensuring the appearance integrity and service life of the metal mesh 2.

The limiting component can then fix the two rectangular frames 1 together. Through the above operation, multiple rectangular frames 1 can be combined together for storage and transportation, which greatly reduces the storage space occupied by a single rectangular frame 1, avoids damage to the rectangular frames 1 caused by stacking and squeezing, and reduces the risk of damage to the rectangular frames 1 caused by collisions and squeezing during transportation.

[0058] Two threaded rods 11 are rotatably installed in two movable slots 7. One end of each threaded rod 11 passes through two sliding blocks 8. The other end of one of the threaded rods 11 passes through one side of the movable slot 7 and extends to the outside, where a knob 12 is fixedly installed.

[0059] Rotating knob 12 causes two threaded rods 11 to rotate. Under the action of the threads, the rotation of the two threaded rods 11 causes two sliding blocks 8 to move. The movement of the sliding blocks 8 compresses the support rod 9, causing it to rotate. Simultaneously, the top of the support rod 9 rotates within the through groove 10. The rotation of the two support rods 9 lifts the lifting rod 4, causing it to move upwards until the rubber pad 5 at the top of the lifting rod 4 touches the shelf. At this point, both rubber pad 5 and rubber pad 6 deform. Under the compression of the lifting rod 4 and the friction between rubber pad 5 and rubber pad 6... Under its function, the rectangular frame 1 can be fixed in a suitable position on the shelf, ensuring that personnel can easily fix the rectangular frame 1 in any position on the shelf.

[0062] Specifically, it is ensured that the two threaded rods 11 can rotate simultaneously, that the threaded rods 11 can rotate normally within the rectangular frame 1, and that the rotation of the threaded rods 11 can drive the sliding block 8 to move.

[0063] Example 4:

[0064] This embodiment provides a high-strength metal open mesh cover, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a limiting component:

[0065] A sliding groove 15 is formed inside a rectangular frame 1 and located below one of the slots 13. A limiting block 16 is slidably installed inside the sliding groove 15. One end of the limiting block 16 passes through one side of the sliding groove 15 and extends to the outside. A spring 17, which is fixed to the inner wall of the sliding groove 15, is fixedly installed at the other end of the limiting block 16. A pressing plate 18 is fixedly installed on one side of the limiting block 16, which passes through the sliding groove 15. A limiting hole 19 is formed on the other side of the rectangular frame 1 and on one side of the sliding groove 15.

[0066] When the entire device is not in use, personnel can insert two inserts 14 on one rectangular frame 1 from top to bottom into two slots 13 on another rectangular frame 1. At the same time, one rectangular frame 1 will press the limiting block 16 on the other rectangular frame 1 to move, causing the limiting block 16 to move and compress the spring 17 to retract until the insert 14 is fully inserted into the slot 13. At this time, under the action of the spring 17's rebound force, the spring 17 will compress the limiting block 16 to reset, so that one end of the limiting block 16 is inserted into the corresponding limiting hole 19, thereby fixing the two rectangular frames 1 together. Through the above operation, multiple rectangular frames 1 can be combined together for storage and transportation, greatly reducing the storage space occupied by a single rectangular frame 1, avoiding damage to the rectangular frames 1 caused by stacking and compression, and reducing the risk of damage to the rectangular frames 1 caused by collisions and compression during transportation. This reduces the overall usage cost of the device from both storage and transportation perspectives and improves the management convenience of the warehousing auxiliary equipment.

[0067] Example 5:

[0068] This embodiment provides a high-strength metal open mesh cover. In addition to the technical solutions of the above embodiments, it also has the following technical features: one end of the limiting block 16 is inclined, and one end of the limiting block 16 is inserted into the limiting hole 19.

[0069] Specifically, it is ensured that the downward movement of the other rectangular frame 1 can squeeze the limiting block 16 to move, and that one end of the limiting block 16 can be inserted into the limiting hole 19.

[0070] Example 6:

[0071] This embodiment provides a high-strength metal open mesh cover. In addition to the technical solutions of the above embodiments, it also has the following technical features: the top end of the support rod 9 is rotatably connected to the through groove 10, the support rod 9 has an inclined structure, and the support rod 9 is movably connected to the movable groove 7 and the through groove 10.

[0072] Specifically, it ensures that the top of the support rod 9 can rotate normally within the through groove 10, guarantees the structural stability of the support rod 9, and ensures that the support rod 9 can rotate and move within the movable groove 7 and the through groove 10.

[0073] Example 7:

[0074] This embodiment provides a high-strength metal open mesh cover. In addition to the technical solutions of the above embodiments, it also has the following technical features: the insert block 14 is inserted into the slot 13, and the cross-section of the slot 13 is T-shaped.

[0075] Specifically, it is ensured that the plug 14 can be inserted into the slot 13 and that the plug 14 will not fall out of the slot 13.

[0076] Working Principle: During use, the operator can place the entire device in a suitable position on the shelf. Then, simply turn knob 12. Turning knob 12 will drive the two threaded rods 11 to rotate. Under the action of the threads, the rotation of the two threaded rods 11 will drive the two sliding blocks 8 to move respectively. The movement of the sliding blocks 8 will compress the support rod 9, causing the support rod 9 to rotate on the sliding blocks 8. Simultaneously, the top of the support rod 9 will rotate within the through groove 10. The rotation of the two support rods 9 can lift the lifting rod 4, causing the lifting rod 4 to move upwards until the rubber pad 5 at the top of the lifting rod 4 touches the shelf. At this point, both rubber pad 5 and rubber pad 6 will deform under the pressure of the lifting rod 4. Under the friction of rubber pad 5 and rubber pad 6, the rectangular frame 1 can be fixed in a suitable position on the shelf, ensuring that personnel can easily fix the rectangular frame 1 in any position on the shelf. Personnel can disassemble and adjust the installation position of the rectangular frame 1 on the shelf at any time according to the actual size and quantity requirements of the goods, thereby flexibly changing the spacing between adjacent rectangular frames 1. When storing large-volume goods, the number of rectangular frames 1 can be reduced or the spacing can be increased to avoid obstruction; when storing small-volume goods, the number of rectangular frames 1 can be increased or the spacing can be reduced to achieve classified storage, effectively avoiding waste of shelf space, significantly improving the adaptability and utilization of warehouse space, and eliminating the need for repeated disassembly and reassembly of the rectangular frame 1, reducing the tedium of operation.

[0077] When the metal mesh 2 is impacted, the presence of two metal meshes 2 connected by several connecting rods 3 gives the metal mesh 2 high strength. Upon impact, the two metal meshes 2 can share the impact force, thereby reducing the probability of damage to the metal mesh 2 and significantly improving the overall structural strength and impact resistance of the metal mesh 2. During cargo handling, even if the metal mesh 2 is collided or lateral pressure is generated by the stacking of goods, the multi-metal mesh 2 combination structure can disperse the force, effectively preventing the metal mesh 2 from undergoing local deformation, dents, or wire breakage, thus ensuring the appearance integrity and service life of the metal mesh 2.

[0078] When the entire device is not in use, personnel can insert the two inserts 14 on one of the rectangular frames 1 from top to bottom into the two slots 13 on the other rectangular frame 1. At the same time, one of the rectangular frames 1 will press the limiting block 16 on the other rectangular frame 1 to move, causing the limiting block 16 to move and compress the spring 17 to retract until the insert 14 is fully inserted into the slot 13. At this time, under the action of the spring 17's rebound force, the spring 17 will compress the limiting block 16 to reset, so that one end of the limiting block 16 is inserted into the corresponding limiting hole 19, thereby fixing the two rectangular frames 1 together. Through the above operation, multiple rectangular frames 1 can be combined together for storage and transportation, greatly reducing the storage space occupied by a single rectangular frame 1, avoiding damage to the rectangular frames 1 caused by stacking and compression, and reducing the risk of damage to the rectangular frames 1 caused by collision and compression during transportation. This reduces the overall usage cost of the device from both storage and transportation perspectives and improves the management convenience of the warehousing auxiliary equipment.
