Description

Technical Field

[0001] The present invention relates to the technical field of shelves, in particular to a bolt-free shelf. Background Art

[0002] Shelves generally refer to racks for storing goods. They are storage equipment used to store finished items and are important tools for warehouse modernization and efficiency improvement. With the rapid economic development, a large number of foreign-funded enterprises have poured into the Yangtze River Delta and Pearl River Delta areas of my country, which not only promoted the development of the local economy, but also brought new management concepts and management technologies. Therefore, the demand for shelves used in corporate warehouses is also increasing.

[0003] For example, an existing patent (publication number: CN220529549U) discloses an adjustable shelf, in which an adjustment mechanism is provided. Through the mutual cooperation between the various structures in the adjustment mechanism, by setting a positioning plate, an adjustment screw, an adjustment handle, a transmission rod, an active bevel gear, a driven bevel gear, a threaded sleeve, a moving block and a limit rod, the combination and separation of the storage partition and the support plate are realized, thereby facilitating the subsequent adjustment of the position of the storage partition according to the size of the goods, and at the same time facilitating the increase or decrease of the number of storage partitions, thereby improving the space utilization rate of the shelf and facilitating the placement of e-commerce goods.

[0004] However, the adjustable shelf designed above still has some disadvantages in actual use: although the adjustable shelf can be inserted into the limit slots of different heights by adjusting the telescopic movement of the limit rod, the distance between two adjacent storage partitions can be adjusted, thereby being suitable for placing goods of different heights. However, since the goods will generate an instantaneous impact force when placed on the storage partition, this impact force will be absorbed by the limit rod, and the limit rod is prone to deformation, which will affect the subsequent adjustment of the storage partition.

[0005] To this end, we designed a boltless shelf to solve the above problems. Summary of the Invention

[0006] The object of the present invention is to provide a boltless shelf to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the present invention provides a boltless shelf, including a frame with fixing openings on both sides, columns fixedly installed in the fixing openings along the vertical direction, multiple positioning openings on one side of the columns, multiple placement plates slidingly arranged in the frame, positioning members on both sides of the placement plates, the positioning members movably sleeved on the columns, a card block slidingly inserted in the positioning member, the other end of the card block slidingly inserted in one of the positioning openings, two sliders symmetrically slidingly arranged in the card block, a back plate provided below the card block, the back plate abutting against the bottom wall in the positioning opening, a rotating member rotatably arranged between the slider and the back plate, a buffer member provided on one side of the slider, the other end of the buffer member provided in the card block.

[0013] Furthermore, a limit seat is fixedly installed between the two rotating parts, a telescopic rod is rotatably arranged between the two limit seats, a third pin is arranged in the limit seat, and the end of the telescopic rod is rotatably sleeved on the third pin.

[0014] Furthermore, an electromagnet is provided on one side of the bottom of the clamping block, and an iron block is provided on one side of the top of the abutment plate. The iron block and the electromagnet cooperate with each other and are magnetically connected.

[0015] Furthermore, it also includes a driving component for driving the card block to move, the driving component includes a slide plate, a fixed cavity and a limiting opening are opened inside the positioning member, the fixed cavity, the limiting opening and the sliding hole are all connected, the slide plate is slidably set in the fixed cavity, the end of the card block away from the positioning opening is slidably inserted in the limiting opening and is fixedly connected to one side of the slide plate, a pull rod is provided on the other side of the slide plate, the other end of the pull rod slides through the positioning member and is provided with a pull block, a support spring is provided between the slide plate and the inner side wall of the fixed cavity, and the support spring is movably sleeved on the pull rod.

[0016] Furthermore, an iron sheet is fixedly mounted on one side of the slide, and a permanent magnet is fixedly mounted on the inner side wall of the fixed cavity. The permanent magnet and the iron sheet cooperate with each other and are magnetically connected.

[0017] Compared with the prior art, the beneficial effect of the present invention is that when the goods are placed on the top of the placement plate, the placement plate will drive the positioning part and the card block to move downward in the positioning port, and at the same time, the two rotating parts will push the sliders away from each other in the installation cavity and compress the buffer spring to absorb the impact force.

[0019] Compared with the prior art, the beneficial effect of the present invention is: by pulling the pull block, the pull block can drive the pull rod and the card block to slide into the interior of the fixed cavity until the card block and the abutment plate slide out of the positioning port at the same time, and the limit on the placement plate can be released. According to the above principle, the card block can be inserted into the appropriate positioning port to adjust the distance between two adjacent placement plates, so that goods of different volumes can be placed conveniently.

[0020] Compared with the prior art, the beneficial effect of the present invention is that the slide plate can be simply limited by the cooperation of the iron sheet and the permanent magnet, which makes it convenient for personnel to operate the block on the other side and improves the convenience during use.

[0021] Compared with the prior art, the beneficial effect of the present invention is that by energizing the iron block, the iron block can absorb the electromagnet, which can reduce the distance between the card block and the abutment plate, avoiding the card block and the abutment plate from having a large distance that makes it inconvenient to insert into the positioning port.

DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0026] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," "connect," and "disposed" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0027] See also Figure 1-6 The present invention provides a technical solution: a boltless shelf, comprising a frame 1 with fixing openings 2 on both sides, a column 3 fixedly installed in the fixing openings 2 along the vertical direction, a plurality of positioning openings 4 on one side of the column 3, a plurality of placement plates 5 slidably arranged in the frame 1, a positioning member 6 is provided on both sides of the placement plate 5, and the positioning member 6 is movably sleeved on the column 3; A card block 8 is slidably inserted in the positioning member 6, and the other end of the card block 8 is slidably inserted in one of the positioning ports 4. Two sliders 9 are symmetrically slidably arranged in the card block 8. A back plate 10 is provided below the card block 8, and the back plate 10 is against the bottom wall of the positioning port 4. A rotating member 11 is rotatably arranged between the slider 9 and the back plate 10. A buffer member is provided on one side of the slider 9, and the other end of the buffer member is provided in the card block 8. A sliding hole 7 is provided in the positioning member 6, and the positioning member 6 is slidably sleeved on the column 3 through the sliding hole 7. The buffer member includes a buffer spring 12 and a damping cylinder 13. One end of the buffer spring 12 and the damping cylinder 13 are fixedly mounted on one side of the slider 9, and the other end of the buffer spring 12 and the damping cylinder 13 are provided in the card block 8, and the buffer spring 12 is movably sleeved on the damping cylinder 13.

[0028] During specific implementation, when the goods are placed on the top of the placement plate 5, the impact force generated by the gravity potential energy of the goods may impact the placement plate 5. At this time, the placement plate 5 will drive the positioning member 6 and the clamping block 8 to move downward in the positioning port 4. During this process, the two rotating members 11 will push the slider 9 away from each other in the installation cavity 16, so that the slider 9 compresses the buffer spring 12 to absorb the impact force. After the impact force is completely absorbed, the buffer spring 12 can slowly rebound in conjunction with the damping cylinder 13, which can avoid the problem of deformation and damage of the clamping block 8 caused by the instantaneous impact of the goods, thereby effectively extending the service life of the clamping block 8.

[0029] See Figure 1-6The bottom of the slider 9 is fixedly installed with a mounting seat 14, and the center of the top of the back plate 10 is fixedly installed with a fixing seat 15. The two ends of the rotating member 11 are respectively rotatably set in the mounting seat 14 and the fixing seat 15. A first pin is provided in the mounting seat 14, and a second pin is provided in the fixing seat 15. The two ends of the rotating member 11 are respectively rotatably sleeved on the first pin and the second pin. The interior and bottom of the block 8 are respectively provided with a mounting cavity 16 and a sliding port 17. The mounting cavity 16 is communicated with the sliding port 17. The slider 9 is slidably connected in the mounting cavity 16. The end of the buffer spring 12 and the damping cylinder 13 away from the slider 9 are both provided on the inner side wall of the mounting cavity 16, and one end of the rotating member 11 is slidably inserted in the sliding port 17.

[0030] During specific implementation, based on the above implementation, the internal components of the card block 8 can be conveniently installed reasonably to ensure normal movement and avoid the problem of movement interference. In addition, for the installation of internal components such as the card block 8 and the positioning member 6, we can divide it into two halves, and open a cavity on it to facilitate the installation of components. Finally, the two halves of the shell can be assembled. Since the division of the card block 8 and the positioning member 6 into two halves and the installation of components are both existing technologies and are not problems that need to be solved in the background technology of this application, they will not be elaborated in detail.

[0031] See Figure 1-6 A limit seat 18 is fixedly installed between the two rotating members 11, and a telescopic rod 19 is rotatably arranged between the two limit seats 18. A third pin is arranged in the limit seat 18, and the end of the telescopic rod 19 is rotatably sleeved on the third pin.

[0032] In a specific implementation, based on the above implementation, when the two rotating members 11 rotate slightly and move away from each other, the telescopic end of the telescopic rod 19 can be extended, and the two rotating members 11 are connected in parallel, which can effectively improve the stability between the two rotating members 11 during use and greatly reduce the probability of the rotating members 11 breaking.

[0033] See Figure 1-6 An electromagnet 20 is provided on one side of the bottom of the clamping block 8, and an iron block 21 is provided on one side of the top of the abutment plate 10. The iron block 21 cooperates with the electromagnet 20 and abuts against it, and is magnetically connected. When the clamping block 8 and the abutment plate 10 need to be inserted into the positioning port 4, the iron block 21 can be energized so that the iron block 21 can attract the electromagnet 20, thereby reducing the distance between the clamping block 8 and the abutment plate 10, thereby preventing the clamping block 8 and the abutment plate 10 from being too far apart and making it difficult to insert into the positioning port 4.

[0034] See Figure 1-6, and also includes a driving component for driving the card block 8 to move, the driving component includes a slide plate 22, a fixed cavity 26 and a limit opening 27 are opened inside the positioning member 6, the fixed cavity 26, the limit opening 27 and the sliding hole 7 are all connected, the slide plate 22 is slidably set in the fixed cavity 26, and the end of the card block 8 away from the positioning opening 4 is slidably inserted in the limit opening 27 and fixedly connected to one side of the slide plate 22, and a pull rod 23 is provided on the other side of the slide plate 22, the other end of the pull rod 23 slides through the positioning member 6, and is provided with a pull block 25, and a support spring 24 is provided between the slide plate 22 and the inner side wall of the fixed cavity 26, and the support spring 24 is movably sleeved on the pull rod 23.

[0035] During specific implementation, based on the above implementation, when it is necessary to adjust the position of the placement plate 5 on the frame 1, the pull block 25 can be pulled horizontally to make the pull block 25 drive the pull rod 23, the slide plate 22 and the card block 8 to slide toward the inside of the fixed cavity 26. At the same time, the slide plate 22 will compress the support spring 24 until the card block 8 and the support plate 10 slide out of the positioning port 4 at the same time. The limit on the placement plate 5 can be released. According to the above principle, the card block 8 can be inserted into the appropriate positioning port 4 to adjust the distance between two adjacent placement plates 5, so that goods of different volumes can be placed conveniently.

[0036] See Figure 1-6 An iron sheet 28 is fixedly mounted on one side of the slide 22, and a permanent magnet 29 is fixedly mounted on the inner wall of the fixed cavity 26. The permanent magnet 29 and the iron sheet 28 are in contact with each other and are magnetically connected. When the iron sheet 28 and the permanent magnet 29 contact each other, the permanent magnet 29 and the iron sheet 28 attract each other, which can easily limit the position of the slide 22, making it easier for personnel to operate the clamping block 8 on the other side, and improving convenience during use.

[0037] In order to protect the goods, we can install an anti-slip member 30 on the top of the placement plate 5, and set the anti-slip member 30 to rubber. Since rubber has a soft texture, it can ensure that the appearance of the goods is not scratched.

[0038] Working principle: When in use, by placing the goods on the top of the placement board 5, they can be stored conveniently. By setting up multiple placement boards 5, the number of stored goods can be increased and their sorting can be facilitated. In addition, the shelf does not require the use of bolts for fixing and motors and other devices, which not only makes the shelf lighter, but also reduces production costs.

[0039] During the above operation, when it is necessary to adjust the position of the placement plate 5 on the frame 1, the pull block 25 can be pulled horizontally so that the pull block 25 drives the pull rod 23, the slide plate 22 and the card block 8 to slide into the interior of the fixed cavity 26. At the same time, the slide plate 22 will compress the support spring 24 until the card block 8 and the support plate 10 slide out of the positioning port 4 at the same time. The limit on the placement plate 5 can be released. According to the above principle, the card block 8 can be inserted into the appropriate positioning port 4 to adjust the distance between two adjacent placement plates 5, so that goods of different volumes can be placed conveniently.

[0040] When the iron sheet 28 and the permanent magnet 29 are against each other, the permanent magnet 29 and the iron sheet 28 will attract each other, which can simply limit the slide plate 22, making it convenient for personnel to operate the block 8 on the other side, thereby improving convenience during use. In addition, when the block 8 and the plate 10 need to be inserted into the positioning port 4, the iron block 21 can be energized so that the iron block 21 can attract the electromagnet 20, thereby reducing the distance between the block 8 and the plate 10, and avoiding the block 8 and the plate 10 from being too large to be convenient for insertion into the positioning port 4.

[0041] In addition, when the goods are placed on the top of the placement plate 5, the impact force generated by the gravity potential energy of the goods may impact the placement plate 5. At this time, the placement plate 5 will drive the positioning member 6 and the card block 8 to move downward in the positioning port 4. During this process, the two rotating members 11 will push the slider 9 away from each other in the installation cavity 16, so that the slider 9 compresses the buffer spring 12 to absorb the impact force. After the impact force is completely absorbed, the buffer spring 12 can slowly rebound in conjunction with the damping cylinder 13, which can avoid the problem of deformation and damage of the card block 8 caused by the instantaneous impact of the goods, thereby effectively extending the service life of the card block 8.

[0042] When the two rotating members 11 rotate slightly and move away from each other, the telescopic end of the telescopic rod 19 will extend. Connecting the two rotating members 11 in parallel can effectively improve the stability between the two rotating members 11 during use and greatly reduce the probability of the rotating members 11 breaking.
