Description

Technical Field

[0001] This invention relates to the technical field of shelving connectors, and more particularly to a shelving connector reinforcement structure. Background Technology

[0002] Shelving, especially adjustable-height warehouse shelving or commercial display shelving, relies heavily on the reliability of the connection between the beams and uprights for its load-bearing capacity and overall stability. Currently, the common connection method involves installing hooks or protrusions on the ends of the beams or on individual connectors, which are then directly hooked into holes or slots on the uprights. While this method is simple to install, it has significant drawbacks: Low connection strength and easy to fall off: Traditional hooks rely solely on gravity and simple geometric shapes for connection. When subjected to impacts, vibrations, or long-term uneven loads perpendicular to the connection surface, they are prone to shaking or even falling out of the post hole, posing a safety hazard.

[0003] Lack of active locking mechanism: After installation, there is a lack of effective secondary locking or anti-detachment mechanism. Once the connection is completed, its connection state is static and passive, unable to cope with dynamic load changes, and the load-bearing capacity has a clear upper limit, limiting the overall load-bearing performance of the rack.

[0004] Installation and disassembly are inconvenient: Some solutions that use additional pins or bolts for reinforcement, while increasing strength, increase the number of installation steps and parts, require tools, are cumbersome to operate, and are inefficient.

[0005] Therefore, there is an urgent need in the existing technology for a rack connector reinforcement solution that can significantly improve connection strength, prevent accidental detachment, and facilitate operation while maintaining convenient installation. This invention aims to solve the above problems through a safety buckle structure that integrates automatic locking and manual unlocking functions. Summary of the Invention

[0006] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0007] In view of the problems existing in the above-mentioned existing shelf connection reinforcement structures, the present invention is proposed.

[0008] Therefore, the purpose of this invention is to provide a reinforcement structure for shelf connectors, which greatly simplifies the installation process and provides an active locking force that traditional hooks do not have, fundamentally preventing accidental detachment in the vertical direction and significantly improving the reliability and safety of the connection.

[0009] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a shelf connector reinforcement structure, comprising: The rack upright and the main body of the connector are provided with a hook-on part for connecting to the rack upright; An automatic locking safety buckle is provided on the main body of the connector and includes a locking component that can extend and retract along its axial direction, a spring reset mechanism that drives the locking component to return to its extended position, and a manual operation part for manual unlocking. The extended end of the locking component has a guide slope. When the main body of the connector is attached to the shelf upright through the hook part, the shelf upright contacts the guide slope and forces the locking component to retract. When the hook part reaches the installation position, the locking component automatically extends under the action of the spring reset mechanism and inserts into the corresponding locking hole on the shelf upright to achieve locking.

[0010] As a preferred embodiment of the shelf connector reinforcement structure of the present invention, the automatic locking safety buckle further includes a housing, which is fixedly connected to or integrally formed on the connector body, and the locking component and spring reset mechanism are disposed inside the housing; the housing has a guide hole for the locking component to pass through, and the inner wall of the guide hole is clearance-fitted with the outer wall of the locking component to restrict the locking component to move only along its axial direction.

[0011] As a preferred embodiment of the shelf connector reinforcement structure of the present invention, the locking component has a radial flange at one end inside the housing, and the spring reset mechanism is sleeved on the locking component and abuts against the radial flange and the inner wall of the housing.

[0012] As a preferred embodiment of the shelf connector reinforcement structure of the present invention, the protruding end of the locking component is spherical, conical, or wedge-shaped to facilitate insertion into the locking hole on the shelf upright.

[0013] As a preferred embodiment of the shelf connector reinforcement structure of the present invention, the hook portion on the main body of the connector is at least one upwardly protruding hook, and the opening direction of the hook is perpendicular to or at an acute angle to the extension and retraction direction of the locking component.

[0014] As a preferred embodiment of the shelf connector reinforcement structure of the present invention, the automatic locking safety buckle is located in the middle of the connector body or near the hook-up part, and the extension direction of the locking component forms an angle of 45° to 90° with the force direction of the hook-up part to optimize the load distribution.

[0015] As a preferred embodiment of the shelf connector reinforcement structure of the present invention, the spring reset mechanism includes a connecting rod connected to the radial flange sidewall, a reset spring sleeved on the outer side of the connecting rod, and the two ends of the reset spring are fixedly connected to the radial flange and the manual operation part, respectively.

[0016] As a preferred embodiment of the shelf connector reinforcement structure of the present invention, the manual operation part is connected to the locking component, and the manual operation part is circular and correspondingly disposed on the outer side of the housing. When a pulling force is applied to the manual operation part, the locking component retracts against the elastic force of the spring reset mechanism, thereby unlocking.

[0017] The beneficial effects of this invention are as follows: By setting a locking component with a guide slope and a spring reset mechanism, one-click automatic locking of the connection is achieved. During installation, simply hang the connector, and the locking component will automatically retract after contacting the column, and automatically pop out to lock after being in place. This greatly simplifies the installation process and provides an active locking force that traditional hooks do not have, fundamentally preventing accidental disengagement in the vertical direction and significantly improving the reliability and safety of the connection. The extension direction of the locking component is at an angle of 45° to 90° with the direction of the hanging force. This angle design allows the locking force to most effectively counteract the main component force that causes the connector to disengage, and distributes the load more scientifically to different parts of the connection system, thereby maximizing the overall load-bearing capacity.

[0026] Reference Figures 1-4 A shelving connector reinforcement structure is provided, comprising: The shelf upright 100 and the connector body 200 are provided with a hook part 201 for connecting with the shelf upright 100. An automatic locking safety buckle 300 is provided on the connector body 200 and includes a locking component 301 that can extend and retract along its axial direction, a spring reset mechanism that drives the locking component 301 to return to its extension direction, and a manual operation part 302 for manual unlocking. The extended end of the locking component 301 has a guide slope. When the connector body 200 is attached to the shelf column 100 through the hook part 201, the shelf column 100 contacts the guide slope and forces the locking component 301 to retract. When the hook part 201 reaches the installation position, the locking component 301 automatically extends under the action of the spring reset mechanism and inserts into the corresponding locking hole 303 on the shelf column 100 to achieve locking. Specifically, the hook part 201 on the connector body 200 is at least one upward protruding hook, and the opening direction of the hook is perpendicular to or at an acute angle to the extension and retraction direction of the locking component 301.

[0027] The automatic locking safety buckle also includes a housing 304, which is fixedly connected to or integrally formed on the connector body 200. The locking component 301 and the spring reset mechanism are located inside the housing 304. The housing 304 has a guide hole for the locking component 301 to pass through. The inner wall of the guide hole is clearance-fitted with the outer wall of the locking component 301 to limit the locking component 301 to move only along its axial direction.

[0028] Specifically, the locking component 301 has a radial flange 305 at one end inside the housing 304. The spring reset mechanism is sleeved on the locking component 301 and abuts against the radial flange 305 and the inner wall of the housing 304. The protruding end of the locking component 301 is spherical, conical, or wedge-shaped to facilitate insertion into the locking hole 303 on the shelf column 100.

[0029] The automatic locking safety buckle 300 is located in the middle of the connector body 200 or near the hook part 201, and the extension direction of the locking component 301 forms an angle of 45° to 90° with the force direction of the hook part 201 to optimize the load distribution.

[0030] The spring reset mechanism includes a connecting rod 306 connected to the side wall of the radial flange 305. A reset spring 307 is sleeved on the outside of the connecting rod 306. The two ends of the reset spring 307 are fixedly connected to the radial flange 305 and the manual operation part 302, respectively. The manual operation part 302 is connected to the locking member 301. The manual operation part 302 is circular and is correspondingly arranged on the outside of the housing 304. When a pulling force is applied to the manual operation part 302, the locking member 301 overcomes the elastic force of the spring reset mechanism and retracts, thereby unlocking.

[0031] The shelf connector reinforcement structure in this embodiment mainly consists of three parts working together: shelf uprights 100, connector body 200, and automatic locking safety buckle 300.

[0032] The main body 200 of the connector is roughly plate-shaped, with one end bent upwards to form two parallel hooks as the hanging part 201. The shelf upright 100 is a square steel pipe with multiple locking holes 303 arranged regularly on its front.

[0033] The automatic locking safety buckle 300 is fixed to the upper middle part of the connector body 200 by welding. It includes a cylindrical housing 304, one end of which is closed and connected to the connector body 200, and the other end has a guide hole.

[0034] The locking component 301 is a cylindrical pin, part of which is located inside the housing, and the other part (the protruding end) can extend through a guide hole. The end of the pin located inside the housing has a disc-shaped radial flange 305. Two parallel connecting rods 306 extend from the side wall of the radial flange 305, and the connecting rods 306 extend outward through corresponding holes in the side wall of the housing. The ends of the two connecting rods 306 located on the outside of the housing are connected to a circular manual operating part 302. Inside the housing, a return spring 307 is sleeved on the locking component 301, with its two ends abutting against the radial flange 305 and the inner wall of the housing, respectively.

[0035] The end of the locking component 301 is machined into a wedge-shaped guide slope, and its side surface is machined with two symmetrical planes.

[0036] Installation and operation process: Installation and Automatic Locking: The installer holds the connector body 200, aligns the two hooks with the two pre-set hanging holes on the shelf upright 100, and hooks them in. During the hook descent, the wedge-shaped guide ramp of the locking component 301 first contacts the surface of the shelf upright 100. As the connector continues to descend, the pressure of the upright surface on the ramp forces the entire locking component 301 to overcome the elastic force of the return spring 307 and retract into the housing. When the hook is fully in place and reaches the designed installation position, the axis of the locking component 301 is precisely aligned with a locking hole 303 on the shelf upright 100. At this point, due to the disappearance of the pressure from the upright surface, the locking component 301, under the strong elastic force of the return spring 307, rapidly and automatically extends, precisely inserting into the locking hole 303, and emitting a "click" confirmation sound. After insertion, the flat side of the locking component engages with the inner wall of the locking hole to prevent rotation. Thus, the main body 200 of the connector not only achieves initial suspension through the hook, but also achieves reliable secondary mechanical locking through the locking component 301 inserted into the column.

[0037] Load-bearing optimization: In this embodiment, the hook mainly bears the downward vertical force (i.e., the direction of force) generated by the weight of the shelf and goods. The extension direction (i.e., the locking direction) of the locking component 301 forms an angle of approximately 75° with the vertical direction (falling within the range of 45°-90°). This design allows the locking component 301 to transfer the pull-out force to the solid material of the shelf upright 100 in the most direct and effective way when the connector tends to come off upwards, rather than the thin edge of the hole wall, thereby greatly improving the pull-out resistance and the load-bearing limit of the overall connection.

[0038] Manual unlocking: When the shelf needs to be disassembled, the operator simply hooks or pinches the circular edge of the manual operating part 302 with their fingers and pulls it outward along the connecting rod 306. Pulling the operating part 302 will cause the radial flange 305 and the locking component 301 to compress the return spring 307 through the connecting rod 306, causing the locking component 301 to fully retract from the locking hole 303 into the housing 304. At this time, the connecting body 200 can be safely lifted upward, allowing the hook to disengage from the upright and completing the disassembly. The entire unlocking process can be completed with one hand without any tools.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
