Description

Technical Field

[0001] This utility model relates to the field of mobile shelving technology, and in particular to a fully sealed manual mobile shelving unit. Background Technology

[0002] Manual mobile shelving mainly consists of three parts: rails, shelves, and chassis. It features high load capacity and ease of use, and is primarily used for storing archives, securities, and other documents. Manual mobile shelving includes semi-enclosed and fully enclosed types. Fully enclosed mobile shelving allows each shelf to be completely closed, providing secure storage for documents and equipment. It offers multiple protective functions, including dustproofing, rodent protection, light protection, and tipping prevention. However, existing mobile shelving systems often have multiple storage areas, with the upper areas being quite tall, requiring tools of equal height to access items, which is time-consuming and laborious.

[0003] The technical solution disclosed in Chinese Patent No. CN214048069U uses a rotating device to embed a rotating wheel into the inside of a circular groove. Since the rotating wheel, which is fixed to the left side of the locking block, is slidably connected to the inside of the inner cylinder, when the rotating wheel is pulled, the locking post, which is fixed to the left side of the locking block, is connected to the inside of the locking groove, and the outer cylinder can be rotated, which enhances safety and practicality. By installing a lifting device, the top layer space inside the second mobile shelving unit can be adjusted. The height of the inner sliding post can be adjusted by the distance that the surface of the inner sliding post moves up and down inside the outer sliding cylinder.

[0004] However, the device still has shortcomings: although it can change the size of the upper and lower spaces inside the mobile shelving unit, if the mobile shelving unit is tall, it is still difficult to retrieve or place items in the upper space, and the process is relatively dangerous. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a fully sealed manual mobile shelving unit.

[0006] The technical solution of this utility model is: a fully sealed manual mobile shelving unit, including a chassis, with a set of doors rotatably connected to the openings on both sides of the chassis.

[0007] Support assembly, which is located inside the chassis and rotatably connected to it.

[0008] Two sets of shelves are symmetrically arranged on the support assembly and are rotatably connected to it.

[0009] The transmission assembly is connected to the chassis and drives the support assembly and the shelf.

[0010] Drive component A connects the chassis and the support component. When drive component A drives the support component to rotate, the two sets of shelves rotate relative to the support component in the opposite direction of the support component's rotation, so that the shelves always remain vertical while the support component is rotating.

[0011] And an auxiliary moving mechanism, which drives the chassis to move when in operation.

[0012] Preferably, the support assembly includes side plate A and side plate B, which are symmetrically arranged inside the chassis, and both side plate A and side plate B are provided with support shaft A, which is rotatably connected to the inner wall of the corresponding side of the chassis.

[0013] Preferably, the transmission assembly includes pulley A, pulley B, and toothed belt A, with pulley A and pulley B having the same specifications. A splined shaft is fixedly mounted on the chassis, passing through and coaxially rotating with support shaft A on side plate A. Pulley A is sleeved on the outside of the splined shaft and coaxially connected to it. Two rotating shafts symmetrically arranged about the axis of the splined shaft on side plate A and rotatably connected to it are arranged. Pulley B is sleeved on the rotating shafts and coaxially connected to them. The pulleys B on both sides are respectively connected to pulley A via a toothed belt A. The ends of the two rotating shafts away from side plate A are fixedly connected to the corresponding shelves. Support shafts B are arranged on the side of the shelves away from side plate A, and each support shaft B is rotatably connected to side plate B.

[0014] Preferably, the drive assembly A includes a handwheel A, the mounting shaft A of the handwheel A is rotatably connected to the chassis, and the mounting shaft is coaxial with the spline shaft.

[0015] Preferably, the auxiliary moving mechanism includes a drive assembly B and a drive wheel. The drive assembly B includes a handwheel B and a toothed belt B. A drive shaft is rotatably connected to the bottom of the chassis, and the drive wheel is coaxially connected to the drive shaft. The mounting shaft B of the handwheel B is rotatably connected to the chassis, and the mounting shaft B is coaxially connected to pulley C. The drive shaft is coaxially connected to pulley D, and pulley C and pulley D are connected by a toothed belt B.

[0016] Preferably, the bottom of the chassis is symmetrically connected to several support wheels.

[0017] Preferably, it also includes a slide rail, with the bottom of the chassis slidably connected to the slide rail.

[0018] Compared with the prior art, the present invention has the following beneficial technical effects:

[0019] By setting up a support component, which rotates with the chassis, both sets of shelves can rotate freely on the support component. The transmission component limits the rotation of the shelves, so that as the support component rotates, the shelves themselves adaptively rotate in the opposite direction at the same angle, thus keeping the shelves in a vertical and very stable state. This structure allows the upper and lower shelves to be switched stably and quickly, making it easy for staff to pick up and put down items on the upper shelf, and ensuring safe operation.

[0026] Example 1

[0027] like Figures 1-5As shown, this utility model proposes a fully sealed manual mobile shelving unit, including a housing 1, a support assembly, shelves 11, a transmission assembly, a drive assembly A, an auxiliary moving mechanism, and a slide rail 12. A set of doors 2 are rotatably connected to the openings on both sides of the housing 1. The support assembly is located inside the housing 1 and rotatably connected to it. The support assembly includes side plates A4 and B5, which are symmetrically arranged inside the housing 1, and each side plate A4 and B5 has a support shaft A at its center, which is rotatably connected to the inner wall of the corresponding side of the housing 1. Two sets of shelves 11 are symmetrically arranged on the support assembly and rotatably connected to it. The transmission assembly is connected to the housing 1 and drives the support assembly and shelves 11. The transmission assembly includes pulleys A7 and B9, and a toothed belt A10, where pulleys A7 and B9 are of the same specifications. A splined shaft 3 is fixedly mounted on the chassis 1. The splined shaft 3 passes through the support shaft A on the side plate A4 and rotates coaxially with it. A pulley A7 is sleeved on the outside of the splined shaft 3 and coaxially connected with it. Two rotating shafts 8 are symmetrically arranged on the side plate A4 about the axis of the splined shaft 3 and are rotatably connected to the side plate A4. A pulley B9 is sleeved on the rotating shaft 8 and coaxially connected with it. The pulleys B9 on both sides are respectively connected to the pulley A7 through a toothed belt A10. The ends of the two rotating shafts 8 away from the side plate A4 are fixedly connected to the center of the corresponding shelf 11. A support shaft B is set at the center of the side of the shelf 11 away from the side plate A4. Each support shaft B is rotatably connected to the side plate B5. The drive assembly A includes a handwheel A6, whose mounting shaft A is rotatably connected to the housing 1. The mounting shaft is coaxial with the spline shaft 3. When the drive assembly A drives the support assembly to rotate, the two sets of shelves 11 rotate relative to the support assembly in the opposite direction of rotation, ensuring that the shelves 11 remain vertical while the support assembly is rotating. The auxiliary moving mechanism moves the housing 1 during operation. Several support wheels 19 are symmetrically and rotatably connected to the bottom of the housing 1. The bottom of the housing 1 is slidably connected to the slide rail 12.

[0028] In this embodiment, when it is necessary to retrieve or place items in the upper storage compartment of the upper shelf 11 inside one of the mobile shelving units, the auxiliary moving mechanism is first used to move the cabinet 1 away from the cabinets 1 on both sides, so that there is enough operating space on both sides of the cabinet 1 for retrieving and placing items. Then, the cabinet doors 2 on both sides are opened, and the handwheel A6 is turned. The handwheel A6 drives the side plates A4 and B5 to rotate, thereby causing the shelf 11 to rotate synchronously with the side plates A4 and B5. At this time, since the pulley B9 rotates in the opposite direction under the pull of the pulley A7 and the toothed belt A10, the two sets of shelves 11 rotate synchronously in the opposite direction to the side plates A4 and B5, and the shelf 11, side plates A4, and side plates B5 rotate at the same speed, so that the shelf 11 always remains in a vertical state, thereby realizing the stable repositioning of the upper and lower shelves 11, which makes it convenient for staff to retrieve and place items.

[0029] Example 2

[0030] like Figure 5 As shown, this utility model proposes a fully sealed manual mobile shelving unit. Compared to Embodiment 1, this embodiment further discloses the structure of an auxiliary moving mechanism. The auxiliary moving mechanism includes a drive assembly B and a drive wheel 14. The drive assembly B includes a handwheel B15 and a toothed belt B18. The bottom of the housing 1 is rotatably connected to a transmission shaft 13, and the drive wheel 14 is coaxially connected to the transmission shaft 13. The mounting shaft B of the handwheel B15 is rotatably connected to the housing 1, and the mounting shaft B is coaxially connected to a pulley C16. The transmission shaft 13 is coaxially connected to a pulley D17, and pulleys C16 and D17 are connected by a toothed belt B18.

[0031] In this embodiment, rotating the handwheel B15 causes the pulley C16 to rotate, which in turn drives the pulley D17, the drive shaft 13, and the drive wheel 14 to rotate via the toothed belt B18. The rotation of the drive wheel 14 causes the entire independent mobile shelving unit to slide along the slide rail 12.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
