Description

Technical Field

[0001] This utility model relates to the field of shelving platforms, and in particular to a shelving platform with a pull-out layer. Background Technology

[0002] A shelving platform uses shelving as floor support and can be designed as a multi-level structure, equipped with stairs, railings, etc. It's a simple shelving system that makes full use of space. Existing mezzanine platforms are composed of simple grid-like steel frames with no equipment at the bottom, facilitating pedestrian access and not obstructing workers from pulling goods. Therefore, shelving used for loading various goods is generally placed on the second floor or higher of the platform. However, there are still inconveniences for factory operations. For example, because the shelving needs frequent replenishment, and goods are generally transported by truck or handcart, workers need to frequently go up and down the platform to replenish stock, which is inconvenient and time-consuming. Meanwhile, the space at the bottom is completely unused during replenishment, resulting in significant space waste. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a platform that can utilize the bottom space of the shelving platform to move the shelving from the second floor to the bottom floor for replenishment. The platform has a structure that allows the shelving to move smoothly and provides shock absorption and cushioning, making it convenient for workers to operate.

[0004] To achieve the above objectives, this utility model provides the following solution:

[0005] A pull-out, layer-changing shelving platform includes a platform base plate, a ladder on one side of the platform base plate, several cabinet shelves on the platform base plate, several through slots on the platform base plate, the cabinet shelves being positioned within the through slots and movable up and down, several hangers on one side of the platform base plate, a lifting structure on the hangers allowing the cabinet shelves to move at a uniform speed, magnetic connection components on the lifting structure and the cabinet shelves, and a damper on the platform base plate to buffer the downward force of the cabinet shelves.

[0006] Furthermore, the cabinet shelf in this utility model has an outer edge at the top and bottom that is wider than the groove rim.

[0007] Furthermore, the cabinet shelf in this invention is provided with a hanging ring at the center of the top and a pull handle at the center of the bottom.

[0008] Furthermore, the hanger in this utility model includes an upright rod installed on the platform base plate and located on one side of the cabinet shelf, and a horizontal bar at the top of the upright rod.

[0009] Furthermore, the lifting structure of this utility model includes a pulley 1 set at the extended end of the crossbar, and a pulley 2 set at the connection between the upright and the crossbar. A coil wheel is set on one side of the bottom of the upright, and a coil spring is set on one side of the coil wheel connected to the rotating end. A lifting rope is tied to the coil wheel, and the lifting rope passes through the pulley 2 and the pulley 1 in sequence and is finally tied to the lifting ring.

[0010] Furthermore, the magnetic connection component in this utility model includes a sub-magnet disposed on one side of the top of the cabinet shelf and a mother magnet disposed at the bottom of the crossbar. The sub-magnet and the mother magnet attract each other, causing the cabinet shelf to be positioned above the through slot.

[0011] Furthermore, the damper in this utility model is mounted on the platform base plate and located on the left and right sides of the cabinet shelf, and touch plates for contacting the moving end of the damper are provided on the left and right sides of the top of the cabinet shelf.

[0012] In summary, the advantages of this utility model over the prior art are:

[0013] This invention provides a platform that utilizes the bottom space of a shelving unit, allowing shelves to be moved from the second floor to the bottom for replenishment. Replenishment is conveniently achieved by taking advantage of the unobstructed nature of the bottom space. After replenishment, the shelves can be moved back to the second floor, restoring the bottom space to its original unobstructed state. The platform features structures that facilitate smooth shelf movement and provide shock absorption. The shelves slide smoothly up and down, and dampers further cushion the impact as they descend, reducing vibration and allowing for a slow, controlled descent that is easy for workers to operate.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] like Figures 1 to 4The present invention preferably provides a pull-type shelf platform, including a platform base plate 1, a ladder 11 on one side of the platform base plate 1, a plurality of cabinet shelves 12 on the platform base plate 1, a plurality of through slots 2 on the platform base plate 1, the cabinet shelves 12 being disposed in the through slots 2 and movable up and down, a plurality of hangers 3 on one side of the platform base plate 1, a lifting structure 4 on the hangers 3 to allow the cabinet shelves 12 to move at a uniform speed, magnetic connection components 5 on the lifting structure 4 and the cabinet shelves 12, and a damper 6 on the platform base plate 1 to buffer the downward force of the cabinet shelves 12.

[0020] The platform base has several legs supporting the bottom, forming the lower space. Several cabinet shelves are located on the upper level of the platform base. Because they are mounted on a through-slot, they can move up and down. When the cabinet shelves are on the upper level, they are suspended by a hanging structure and fixed to the hanging structure by magnetic connections. Manually, the cabinet shelves can be moved downwards through the through-slot. At this point, the magnetic connections disengage, and the cabinet shelves are pulled by the hanging structure, ensuring smooth movement. Therefore, the downward movement is very stable. During the downward movement, dampers further slow down the downward speed of the cabinet shelves, enhancing stability and preventing excessive impact from rapid descent. When manually pushing the cabinet shelves upwards, the hanging structure allows the user to move them upwards without expending excessive force until the magnetic connections re-engage.

[0021] The cabinet shelf 12 described in this utility model has an outer edge 71 at the top and bottom that is wider than the perimeter of the through groove 2. The outer edge prevents the cabinet shelf from detaching from the through groove.

[0022] The cabinet shelf 12 of this utility model has a hanging ring 72 at the top center and a pull handle 73 at the bottom center. The hanging ring is used to connect the lifting structure, and the pull handle is used for easy manual pulling.

[0023] The hanging bracket 3 described in this utility model includes an upright 31 mounted on the platform base plate 1 and located on one side of the cabinet shelf 12, and a horizontal bar 32 located at the top of the upright 31. The connection between the upright and the horizontal bar forms an inverted L-shape, and the bottom of the upright is fixedly connected to the platform base plate.

[0024] The lifting structure 4 described in this utility model includes a pulley 41 at the extended end of the horizontal bar 32 and a pulley 42 at the connection between the vertical bar 31 and the horizontal bar 32. A coiling wheel 43 is provided on one side of the bottom of the vertical bar 31, and a coil spring 44 is provided on one side of the coiling wheel 43 connected to the rotating end. A lifting rope 45 is tied to the coiling wheel 43. The lifting rope 45 passes through the pulley 42 and the pulley 42 in sequence and is finally tied to the lifting ring 72. The pulleys 41 and 42 allow the lifting rope to move smoothly, and the lifting rope is tied to the lifting ring to connect to the cabinet shelf. When the cabinet shelf moves up and down, the coiling wheel will rotate, releasing or rewinding the lifting rope. When the cabinet shelf moves down, the lifting rope is released and the coil spring tightens to reduce the downward force; when the cabinet shelf moves up, the lifting rope is rewinded and the coil spring provides an auxiliary upward force.

[0025] The magnetic connection component 5 described in this invention includes a sub-magnet 51 disposed on one side of the top of the cabinet shelf 12, and a female magnet 52 disposed at the bottom of the crossbar 32. The sub-magnet 51 and the female magnet 52 attract each other, causing the cabinet shelf 12 to be positioned above the slot 2. The magnetic connection between the sub-magnet and the female magnet allows the cabinet shelf to be stably positioned on the upper level of the platform. The magnetic connection component can only be disconnected and the cabinet shelf lowered by the user pulling the handle.

[0026] The damper 6 described in this invention is mounted on the platform base plate 1 and located on the left and right sides of the cabinet shelf 12. Touch plates 61 for contacting the movable ends of the damper 6 are provided on the top left and right sides of the cabinet shelf 12. The damper uses an existing rod-type damper, which can reduce the pressure on the touch plates of the descending cabinet shelf, providing a damping sensation before the cabinet shelf reaches the bottom.
