[0010] According to the above technical solution, a side of the sliding block close to the contact block is fixedly connected to a fixed block, and a side of the fixed block away from the sliding block is fixedly connected to a load-bearing rod.

[0011] According to the above technical solution, a load-bearing plate is fixedly connected to the bottom side of the support block close to the sliding block, a load-bearing rod is fixedly connected to the bottom of the load-bearing plate, and two groups of support mechanisms are arranged symmetrically with the middle of the partition as the center.

[0017] Compared with the prior art, the present invention provides a classification storage device for wholesale of computer hardware, which has the following beneficial effects:

[0018] 1. The present invention can provide strong support for one side of the support block by setting the first spring. When the top of the first spring is under pressure, its strong rebound force can prop up the support block. In this way, the first spring can efficiently support the top of the support block, thereby effectively preventing the support block from deflecting and ensuring the stability and reliability of the entire device.

[0019] 2. The present invention can effectively perform the pulling operation on the pull rope by setting the first rotating block. The hook plate can be pulled with the help of the pull rope, thereby preventing the pushing block from directly contacting the moving block during the downward movement. This means that when the pushing block needs to move downward, the restriction on the pull rope must be released. Such a design can protect the pushing block from accelerating downward when moving downward, thereby ensuring the stability and safety of the entire device operation.

[0020] 3. The present invention can play an important role in the downward movement of the push rod by arranging a clamp. When the driving force of the push rod is large, the clamp can release the connection with the block, so that the push rod can move further downward. When the driving force of the push rod is insufficient, the clamp can support the push rod by relying on the connection with the block. In this way, the space created by the moving distance of the push rod can be protected and the space can be effectively supported and limited.

[0021] 4. The second movable ring provided in the present invention can effectively limit the downward pushing distance of the curved rod. When the curved rod is moving downward, the third spring will contact the third movable ring, so that the third spring can support the parts driven by the curved rod by its own elastic strength, making it more difficult for the curved rod to move downward. When the third spring is compressed, the second movable ring will support the third spring, causing the third movable ring to be unable to move any further, thereby realizing overload protection for the downward moving distance of the curved rod.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] Example 1: See Figure 1-Figure 4 The present invention provides a technical solution: a classification storage device for wholesale computer hardware, comprising a base 1 and four groups of support legs 2, the four groups of support legs 2 are fixedly connected to the four corners of the top of the base 1, the tops of the four groups of support legs 2 are respectively fixedly connected to a placement cabinet 3, the inner wall of the placement cabinet 3 is provided with a partition 4, the upper and lower ends of the partition 4 are fixedly connected to the inner wall of the placement cabinet 3, and the left and right ends of the partition 4 are provided with a sliding groove 8, and also includes:

[0035] The supporting mechanism 5 comprises a sliding block 501, a side of the sliding block 501 close to the partition 4 is slidably connected thereto, a side of the sliding block 501 away from the partition 4 is fixedly connected with a cross bar 509, a side of the cross bar 509 away from the sliding block 501 is fixedly connected with a contact block 504, and two groups of first springs 503 are fixedly connected to the top of the contact block 504. By setting the first springs 503, strong support on one side can be provided for the supporting block 502. When the top of the first spring 503 is under pressure, its strong resilience can prop up the supporting block 502. In this way, the first spring 503 can efficiently support the top of the supporting block 502, thereby effectively preventing the supporting block 502 from being blocked. The support block 502 is offset, and the tops of the two groups of first springs 503 are fixedly connected to the support blocks 502. The outer walls of the support blocks 502 are in contact with the inner walls of the placement cabinet 3. The side of the support block 502 away from the placement cabinet 3 is fixedly connected to the curved rod 505, the side of the sliding block 501 close to the contact block 504 is fixedly connected to the fixed block 506, the side of the fixed block 506 away from the sliding block 501 is fixedly connected to the load-bearing rod 507, the bottom side of the support block 502 close to the sliding block 501 is fixedly connected to the load-bearing plate 508, and the bottom of the load-bearing plate 508 is fixedly connected to the load-bearing rod 507. There are two groups of support mechanisms 5, and they are symmetrically arranged with the middle of the partition 4 as the center.

[0036] The working principle of this embodiment is as follows: when the user needs to classify and store the parts, the larger parts are placed on the support block 502 first. At this time, when the user places the parts on the side close to the placement cabinet 3, the support block 502 will be pressed down by the pressing force, causing the first spring 503 to receive the pressing force and start to shrink, but the first spring 503 will lift the support block 502 again through its own resilience, and the first spring 503 will also transfer a part of the pressing force to the contact plate 5904. The resilience of the first spring 503 can ensure that the support block 502 will not tilt toward the side of the placement cabinet 3, so that the support block 502 will not be hindered when moving downward, and when the sliding block 501 slides in the sliding groove 8, it is supported by the load-bearing rod 507 and the load-bearing plate 508. When the sliding block 501 slides, it has the driving force of the weight of the parts to slide better in the sliding groove 8, and when the sliding block 501 slides downward, it will drive the curved rod 505 to slide downward synchronously through the support block 502.

[0037] Example 2: Please refer to Figure 5-Figure 6 On the basis of the first embodiment, the present invention provides a technical solution: a moving mechanism 6, the moving mechanism 6 includes a top plate 601, the top plate 601 is fixedly connected to the side of the placement cabinet 3, the top plate 601 is fixedly connected to the first sliding rod 602 at the bottom, the first sliding rod 602 is fixedly connected to the bottom of the bottom plate 603, the side of the bottom plate 603 close to the placement cabinet 3 is fixedly connected to the first sliding rod 602, the first sliding rod 602 passes through the curved rod 505 and is slidably connected to it, the top of the bottom plate 603 is fixedly connected to the side away from the first sliding rod 602, the top of the telescopic rod 611 is fixedly connected to the moving block 604, the top of the moving block 604 is fixedly connected to the second spring 605, the left and right sides of the top of the moving block 604 are rotatably connected to the first rotating block 606 through the rotating shaft, and the two groups of first rotating blocks 606 The bottom is fixedly connected with a pull rope 607, and the pull rope 607 can be effectively pulled by setting a first rotating block 606. The pull rope 607 can be used to pull the hook plate 610, thereby preventing the pushing block 608 from directly contacting the moving block 604 during the downward movement, so that when the pushing block 608 needs to move downward, the restriction on the pull rope 607 must be released, which can protect the pushing block 608 from accelerating downward during the downward movement. The top of the second spring 605 is fixedly connected with a pressing block 612, and the bottom of the pressing block 612 is fixedly connected with two groups of arc blocks 609, and the left and right sides of the pressing block 612 are fixedly connected with pushing blocks 608, and the bottoms of the two groups of pushing blocks 608 are rotatably connected with hook plates 610 through rotating shafts. The moving mechanism 6 is provided with two groups and is symmetrically arranged with the middle of the partition 4 as the center.

[0038] The working principle of this embodiment is as follows: when the curved rod 505 moves downward, it will slide on the first sliding rod 602. At this time, the curved rod 505 will drive the pressing block 612 to move downward, so that the pressing block 612 will drive the pushing block 608 to move downward synchronously when moving downward, so that the pushing block 608 will drive the hook plate 610 to move downward. At this time, the hook plate 610 will be restricted by the pull rope 607, resulting in the pushing block 608 being unable to contact the moving block 604, thereby pressing it. When there are more parts on the support block 502, a heavier pressing force will be applied to the curved rod 505. At this time, the pressing block 612 will press the second spring 605, causing the second spring 605 to begin to contract, so that the arc block 609 will contact the first rotating block 606, and will continue to apply a driving force, causing the first rotating block 606 to rotate downward, causing the pull rope 607 to begin to relax, causing the hook plate 610 to lose the pulling force and begin to rotate downward due to gravity, causing the hook plate 610 to contact the inner wall of the moving block 604, and under the push of the pushing block 608, the moving block 604 moves downward, causing the telescopic rod 611 to begin to contract.

[0039] Example 3: Please refer to Figure 7-Figure 8On the basis of the first and second embodiments, the present invention provides a technical solution: a protection mechanism 7, the protection mechanism 7 includes a protection shell 701, the side of the protection shell 701 close to the placement cabinet 3 is fixedly connected thereto, the inner wall of the protection shell 701 is provided with two groups of second sliding rods 704, the upper and lower ends of the two groups of second sliding rods 704 are fixedly connected to the inner wall of the protection shell 701, the upper outer walls of the two groups of second sliding rods 704 are provided with a first moving ring 702, the bottoms of the two groups of first moving rings 702 are fixedly connected with a top rod 703, the lower outer walls of the two groups of second sliding rods 704 are slidably connected with a second moving ring 705, the middle ends of the two groups of second sliding rods 704 are slidably connected with a third moving ring 707, and the tops of the two groups of second moving rings 705 are fixed A third spring 706 is fixedly connected, and the tops of the two groups of third springs 706 are fixedly connected to the bottom of the third movable ring 707. The second movable ring 705 is set to effectively limit the downward pushing distance of the curved rod 505. When the curved rod 505 moves downward and causes the third spring 706 to contact the third movable ring 707, the third spring 706 supports the parts driven by the curved rod 505 by its own elastic strength, making it more difficult for the curved rod 505 to move downward. When the third spring 706 is compressed, the second movable ring 705 supports the third spring 706, causing the third movable ring 707 to be unable to move any further, thereby realizing overload protection for the downward moving distance of the curved rod 505. Four groups of fixed seats 709 are provided on the inner wall of the protective shell 701. The four groups of fixed seats 709 are rotatably connected with rotating blocks 708 through rotating shafts. The tops of the four groups of rotating blocks 708 are in contact with the bottom of the second moving ring 705. The rotating block 708 on the side close to the placement cabinet 3 is fixedly connected with a clamp 711, and the rotating block 708 on the side away from the placement cabinet 3 is fixedly connected with a clamp 710. The two groups of clamps 710 are clamped with the two groups of clamps 711. By setting the clamp 710, the process of the push rod 703 moving downward can be detected. When the driving force when the push rod 703 moves downward is large, the clamp 710 can release the connection with the clamp 711, so that the push rod 703 can move further downward; and when the driving force of the push rod 703 is insufficient, the clamp 710 can support the push rod 703 by virtue of the connection with the clamp 711. In this way, the space created by the moving distance of the push rod 703 can be protected, and the space can be effectively supported and limited.

[0040] The working principle of this embodiment is as follows: when the curved rod 505 moves downward, it will also drive the first moving ring 702 to move downward, so that the first moving ring 702 will slide downward on the second sliding rod 704 under the push of the curved rod 505. When the first moving ring 702 slides downward to a certain distance, the push rod 703 will be inserted into the inner wall of the third moving ring 707. At this time, if the push rod 703 continues to move, it will contact the rotating block 708, so that the rotating block 708 will support the push rod 703. When the downward movement force of the push rod 703 is unable to push the rotating block 708 open, the curved rod 505 cannot move. At this time, the moving distance of the support block 502 has reached the required space. When the push rod 703 continues to move downward to push the rotating block 708 open, the clamp 710 will move out from the clamping block 711, causing the push rod 703 to pass through the third moving ring 707, causing the first moving ring 702 to contact the third moving ring 707, and will push the third moving ring 707 to move downward. At this time, the third moving ring 707 will contact the third spring 706, causing the third spring 706 to support the third moving ring 707. Since the space of the support block 502 is already very large at this time, if it continues to expand, it will occupy the space of other parts, resulting in the inability to achieve the conditions for classified storage of parts.
