Abstract
Description
Technical Field
[0001] This invention relates to the field of safety protection technology for shelving units, specifically to a safety locking component for a shelving unit's load-bearing platform and the shelving unit itself. Background Technology
[0002] In existing shelving systems, the load-bearing platform is typically installed horizontally within the crossbeam track groove via a sliding plug-in connection for easy position adjustment. However, this structure presents a safety hazard: when the load-bearing platform is under heavy load or subjected to external impact, it is prone to accidental dislodgement due to a gap between the track groove and the locking components, leading to a safety accident. To address this issue, existing technologies often employ methods such as increasing friction or using auxiliary fasteners, but these methods suffer from complex operation and low locking reliability. Therefore, there is an urgent need for a locking mechanism that combines convenient assembly and disassembly with high safety. Utility Model Content
[0003] To address the aforementioned issues, this invention provides a safety locking component and shelf structure for a load-bearing platform, aiming to improve the stability of the connection between the load-bearing platform and the crossbeam through a mechanical locking structure, and to prevent the risk of accidental detachment.
[0004] A safety locking assembly for a shelf platform includes a mounting plate fixedly connected to an external platform, a hook fixedly connected to one side of the mounting plate, a locking member that is movably hinged to the mounting plate or the hook, and fasteners for controlling the locking member to flip and lock. The hook has an upwardly curved hook-shaped portion at its outer end, which is fitted into an external upper slot. The locking member can flip relative to the hook. When one end of the locking member is tilted upward, the other end of the locking member is tilted downward and forms a locking and opening structure with the hook-shaped portion, which abuts against the upper and lower surfaces of the slot.
[0005] Preferably, the locking member has a Z-shaped structure, and the locking member has a pivot for a movable hinged mounting plate or a hook in the middle. The locking member includes a locking top plate, a longitudinal connecting plate and a locking bottom plate that are integrally connected in sequence. The locking bottom plate is adapted to be installed in a receiving groove provided at the bottom of the mounting plate. When the locking top plate is not flipped open relative to the hook, there is a flipping gap between the upper surface of the locking bottom plate and the bottom surface of the receiving groove. When the locking member is flipped open relative to the hook, the locking bottom plate tilts upward and is limited to abut against the bottom surface of the receiving groove.
[0006] Preferably, the flipping gap is provided with an elastic element for supporting the locking base plate and the bottom surface of the receiving groove.
[0007] Preferably, the bottom of the receiving groove is provided with an upper through hole, and the locking base plate is provided with a lower through hole corresponding to the upper through hole. The fastener is provided in the upper through hole and the lower through hole, and the fastener is used to control the relative position of the locking base plate and the mounting plate.
[0008] Preferably, the elastic element is an elastic sponge or a spring that fits into a fastener.
[0009] Preferably, the fastener is a screw or bolt fastening assembly, wherein the screw is threadedly connected to the upper through hole, and the bolt fastening assembly consists of a bolt passing through the upper and lower through holes and a nut located above the mounting plate.
[0010] A storage rack includes a load-bearing unit and a horizontally arranged crossbeam. The load-bearing unit includes a load platform and a safety locking assembly. The mounting plate of the safety locking assembly is fixedly connected to the bottom of the load platform. The crossbeam has a track groove extending along the length of the crossbeam. The opening of the track groove is located on the side. The track groove is fitted with a hook. The upper end of the track groove has an upper slot that forms a locking connection with the hook-shaped part.
[0011] Preferably, the bottom outer side of the track groove is provided with a lower locking groove, the load platform includes a horizontal load plate, the lower end of the horizontal load plate is fixedly connected to an installation plate, and the lower end face of the hook member is provided with a locking flange that is adapted to the lower locking groove to form a buckle. When the user flips the locking bottom plate of the locking member upward, the entire locking member uses the lever principle to make the locking top plate of the locking member flip down and abut against the bottom inner side of the track groove, so that the two ends of the hook member and the locking member are in a staggered open state, and the hook member and the locking member are respectively locked in the inner end of the track groove, so that the locking component and the track groove are locked.
[0012] Preferably, the latching component includes two symmetrically arranged latching modules, with an installation gap between the two latching modules for hinged installation of the locking component. Each latching module includes a transverse latch and a longitudinal baffle arranged perpendicularly to each other. The transverse latch and the track groove form a latching insertion fit. The upper part of the outer end of the transverse latch is provided with the hook-shaped part, and the lower end face of the transverse latch is provided with the latching flange. The lower part of the longitudinal baffle is fixedly connected to the mounting plate, and the longitudinal baffle and the outer end of the track groove form a latching abutment fit.
[0013] Preferably, the load-bearing platform further includes a drawer fixedly connected to the lower end of the horizontal load-bearing plate or a model fixedly connected to the upper end of the horizontal load-bearing plate.
[0014] Beneficial effects: The safety locking component described in this application enables the detachable installation of the load platform through the hook and latch. The corresponding safety locking function is achieved by the contraction and misalignment of the locking component and the hook and latch, thus preventing the load platform from falling off during accidental contact.

[0024] The following is in conjunction with the appendix Figure 1-7 The present invention will be further described with reference to Example 1.
[0025] Example 1: As Figure 1-7 As shown, a storage rack includes a load-bearing unit and a horizontally arranged crossbeam 14. The load-bearing unit includes a load platform and a safety locking assembly. The load platform includes a horizontal load plate 15, the lower end of which is fixedly connected to a mounting plate 1. The load platform also includes a drawer fixedly connected to the lower end of the horizontal load plate 15 or a model fixedly connected to the upper end of the horizontal load plate 15. The crossbeam 14 has a track groove 19 extending along its length. The opening of the track groove 19 is located on the side. The upper end of the track groove 19 has an upper locking groove, and the lower outer side of the track groove 19 has a lower locking groove 16.
[0026] The safety locking assembly includes a mounting plate 1 fixedly connected to an external load-bearing platform, a hook 2 fixedly connected to one side of the mounting plate 1, a locking component 3 that movably hinges the mounting plate 1 or the hook 2, and a fastener 4 for controlling the locking component 3 to flip and lock. The hook 2 includes two symmetrically arranged locking modules, with an installation gap between the two locking modules for hinged installation of the locking component 3. Each locking module includes a transverse locking tongue 17 and a longitudinal baffle 18 arranged perpendicularly to each other. The transverse locking tongue 17 and the track groove 19 form a locking insertion fit. The upper part of the outer end of the transverse locking tongue 17 is provided with a hook-shaped part 5 that fits the upper locking groove. The lower end face of the transverse locking tongue 17 is provided with a locking flange 20 that fits the lower locking groove 16. The lower part of the longitudinal baffle 18 is fixedly connected to the mounting plate 1, and the longitudinal baffle 18 and the outer end of the track groove 19 form a locking abutment fit.
[0027] like Figure 3-8 As shown, the locking component 3 has a Z-shaped structure. The locking component 3 has a pivot 6 in its middle that allows for the movable hinge of the mounting plate 1 or the hook component 2. The locking component 3 includes a locking top plate 7, a longitudinal connecting plate 8, and a locking bottom plate 9 connected sequentially and integrally. The locking bottom plate 9 is fitted into a receiving groove 10 at the bottom of the mounting plate 1. When the locking top plate 7 is not flipped open relative to the hook component 2, there is a flipping gap between the upper surface of the locking bottom plate 9 and the bottom surface of the receiving groove 10. When the locking component 3 is flipped open relative to the hook component 2, the locking bottom plate 9 tilts upwards and abuts against the bottom surface of the receiving groove 10. The bottom of the receiving groove 10 has an upper through hole 12, and the locking bottom plate 9 has a lower through hole 13 corresponding to the upper through hole 12. Fasteners 4 are installed in the upper through hole 12 and the lower through hole 13. The fasteners 4 are used to control and fix the relative position of the locking bottom plate 9 and the mounting plate 1. The flipping gap is provided with an elastic element 11 for supporting the bottom surface of the locking base plate 9 and the receiving groove 10. The elastic element 11 is an elastic sponge or a spring that fits onto the fastener 4. The fastener 4 is a screw that is threadedly connected to the through hole 12.
[0028] like Figure 8 As shown, when the locking element 3 is in the unlocked state, the locking base plate 9 is pre-tightened by the elastic element 11 to maintain the gap with the bottom surface of the receiving groove 10, and the locking top plate 7 is parallel to the hook element 2. At this time, it is convenient for the user to insert the hook element 2 and the locking element 3 into the track groove 19. Figure 7 As shown, when locking is required, the locking base plate 9 is flipped upward by tools or manually, such as by rotating the screws to make the locking base plate 9 flip upward and tilt up. Using the lever principle, the locking top plate 7 is flipped down and pressed against the bottom inner side of the track groove 19. At the same time, the hook-shaped part 5 of the hook 2 engages with the upper slot and the locking flange 20 engages with the lower slot 16, forming a double-point misaligned locking, completely eliminating the risk of the load platform falling off.
[0029] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
