A magnetic tabletop structure made of enameled steel plate

Abstract

This utility model specifically relates to a magnetic tabletop structure made of enameled steel plate, comprising an enameled tabletop hinged to a wall and legs. The top of each leg is rotatably connected to a flip-plate via a pivot. One end of the flip-plate has a magnetic suction end with a magnet, and the other end serves as a support end. The side of each leg has a movable limiting block driven by a knob, gear, and rack, which can extend and retract synchronously to lock the support end. This utility model employs a "first suction, then support" workflow: the magnetic suction end temporarily fixes the legs to the upper surface of the tabletop to bear weight; after all legs are in place, the flip-plate is flipped to make the support end press against the bottom surface of the tabletop, and finally, the movable limiting block locks it in place, allowing for convenient and safe installation and storage by a single person. Simultaneously, the flip-plate and the limiting block form a statically indeterminate triangular support structure, transforming the force on the long connecting rod into compressive stress on the short rod, resulting in significantly better load-bearing stability and bending resistance than traditional connecting rod supports.

Description

Technical Field

[0001] This utility model relates to the field of folding table technology, specifically a magnetic table structure made of enameled steel plate. Background Technology

[0002] Enameled steel sheets, with their excellent wear resistance, corrosion resistance, easy cleaning, and beautiful texture, are increasingly becoming the ideal tabletop material for folding tables in modern homes and commercial spaces. However, because the base material is steel, the finished tabletop is much heavier than those made of wood or composite boards, which brings unique technical challenges to its application as a folding tabletop.

[0003] Currently, the structures used to support heavy-duty folding tables on the market mainly suffer from two types of problems. The first type uses a simple linkage brace structure. This type of structure often lacks sufficient mechanical strength and rigidity when dealing with the large mass of the enameled steel plate. Under long-term heavy pressure or dynamic loads, it is prone to plastic bending or even breakage, posing significant safety hazards and failing to meet the requirements for durable and reliable use. The second type is a more stable non-linkage vertical support structure. Although its load-bearing capacity is improved, it presents significant inconveniences in installation and use. Specifically, when unfolding the table, one person must continuously lift and maintain the heavy table while another person installs and secures the support structure. Conversely, folding it up also requires two people working together. This process is not only time-consuming and labor-intensive but also places excessive demands on the user's cooperation and physical strength, essentially leading to a situation where "one person cannot operate independently," greatly limiting the applicable scenarios and user experience of this type of product. Utility Model Content

[0004] The purpose of this invention is to provide a magnetic tabletop structure for enameled steel plates to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is: a magnetic tabletop structure for an enamel steel plate, comprising an enamel tabletop and legs. The enamel tabletop is hinged to a vertical wall. The top of the legs is rotatably connected to a flip plate via a pivot. One end of the flip plate has a magnetic end, on which a magnet is fixedly mounted. The other end of the flip plate has a support end. Movable limiting blocks are respectively provided on two sides of the top of the legs. The movable limiting blocks are slidably disposed in pre-reserved holes at the top of the legs and located on the side relatively away from the enamel tabletop, used to limit the flip angle of the support end. A rack is fixedly connected to the inward side of the movable limiting blocks. A gear is meshed between the racks of the two movable limiting blocks. A knob is rotatably disposed on the top surface of the legs at the position corresponding to the gear. The gear and the knob are coaxially fixedly connected. The knob can control the movable limiting blocks to extend outward or retract inward.

[0006] Preferably, the number of legs is greater than two, and they are arranged in two groups on both sides of the enamel tabletop; wherein the legs closest to the wall are connected to each other by a telescopic structure, and are also connected to the legs on the other side by the telescopic structure.

[0007] Preferably, a fixing limit block is provided on each of the two sides of the top of the support leg. The fixing limit block is fixedly installed on the side near the enamel tabletop to limit the flipping angle of the magnetic end.

[0008] Preferably, the enamel tabletop is rotatably connected to the wall via a damping hinge.

[0009] Preferably, the magnet is a neodymium iron boron strong magnet.

[0010] This utility model provides an improved magnetic tabletop structure for enameled steel plates, which has the following improvements and advantages compared with the prior art: Firstly, this utility model utilizes a flap structure at the top of the support leg. In the supported state, the flap acts as a single lever, with its supporting end pressing against the bottom of the tabletop. Together with the movable limiting block, these components form a statically indeterminate, stable triangular support structure, transforming the easily bent long connecting rod into a shorter, more resistant rod composed of the flap. This structure effectively converts the vertical load of the tabletop into pressure within the flap and reaction force from the support leg, thereby significantly improving the support rigidity and bending resistance, sufficient to stably support heavy enamel tabletops over a long period. Secondly, the key to this invention is its pre-attachment, post-support workflow: the user can first lift each tabletop individually and immediately use the strong magnets at the flip-up magnetic ends to temporarily fix it to the surface of the enamel tabletop. During this process, the magnetic force reliably bears the entire weight of the tabletop, freeing the user's hands and allowing them to easily perform subsequent operations. After all the legs are temporarily fixed by magnetic attraction, each flip-up panel is rotated 180° to put the support end into a supporting state. Finally, the knobs are tightened sequentially to lock the movable limit blocks. The entire process is clear and labor-saving, requiring only one person to safely and conveniently complete the installation and disassembly of the tabletop. Attached Figure Description

[0013] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0014] This utility model provides an improved magnetic tabletop structure for an enameled steel plate. The technical solution of this utility model is as follows: like Figures 1-7 As shown, a magnetic tabletop structure made of enamel steel plate includes a flip plate 5 at the top of the support leg 3 and its adjustment and locking mechanism.

[0015] The flip panel 5 is rotatably connected to the top of the support leg 3 via a pivot 14, allowing the flip panel 5 to rotate 180° around the pivot 14. One end of the flip panel 5 is a magnetic end 6, on which a magnet 7 is fixedly mounted. The other end of the flip panel 5 is a support end 8, which contacts the lower surface of the enamel tabletop 1 when in a supported state.

[0016] When the table needs to be unfolded, the user first aligns the support leg 3 in the corresponding position so that the magnet 7 of the magnetic end 6 of the flip panel 5 at its top faces downwards. Then, the enamel table panel 1 is lifted from the wall 2 to a near-horizontal position. At this time, the magnetic end 6 will automatically attach to the upper surface of the enamel table panel 1. The strong magnetic force will immediately and temporarily fix the enamel table panel 1 to the support leg 3, fully supporting the weight of the enamel table panel 1 at that position, thus freeing the user's hands.

[0017] After all the support legs 3 are temporarily secured magnetically, the user flips each flap 5 180° in sequence, so that the supporting end 8 rotates to the bottom of the enamel tabletop 1 and contacts it. At this time, rotating the knob 13 drives the gear 12, which is fixed coaxially with it, to rotate. The gear 12 drives the racks 11 on both sides and the movable limiting blocks 10 fixed with them to extend outward synchronously from the holes on the side of the support leg 3, thereby locking the supporting end 8 of the flap 5, restricting its rotation, and locking the flap 5 in the support position.

[0018] In this supported state, the flap 5 acts as a single lever, with its supporting end 8, the supporting point on the lower surface of the table, and the fulcrum formed by the movable limiting block 10, together forming a statically indeterminate stable triangular support structure. This structure transforms the force on the traditional long connecting rod into the compressive stress on the flap 5 rod, greatly improving its bending resistance and support rigidity.

[0019] Furthermore, to ensure the stability and coordination of the multiple support legs 3, the number of support legs 3 is greater than two, and they are arranged in two groups on both sides of the enamel tabletop 1. Support legs 3 located on the same side, as well as those closer to the wall 2 and those farther from the wall 2, are interconnected via a telescopic structure 4. This telescopic structure 4 is a telescopic sleeve rod, whose function is to form a stable overall frame with all support legs 3, preventing individual support legs 3 from swaying or tilting inward, thus further enhancing the stability and reliability of the entire support system.

[0020] Furthermore, fixing limit blocks 9 are fixedly installed on the two sides of the top of the support leg 3, and are positioned close to the enamel tabletop 1. The function of the fixing limit block 9 is that when the flip plate 5 is in a temporarily fixed state (i.e., when the magnetic end 6 is attached to the upper surface of the tabletop), the support end 8 will abut against the fixing limit block 9, thereby limiting the flip angle of the flip plate 5 and keeping it in an optimal position that facilitates subsequent operations, ensuring smooth and precise operation.

[0021] Furthermore, the enamel tabletop 1 is rotatably connected to the vertical wall 2 via a damping hinge. The damping hinge provides uniform cushioning force, ensuring that when the user lifts or lowers the heavy enamel tabletop 1, the tabletop will not fall rapidly or impact the wall 2 due to its own weight, making the operation process smoother, safer, and less strenuous.

[0022] Furthermore, to ensure sufficient magnetic attraction for reliable temporary fixation, the magnet 7 is preferably a neodymium iron boron strong magnet. This type of magnet has an extremely high magnetic energy product, enabling it to generate extremely strong attraction in a small volume, sufficient to withstand the partial weight of the heavy enamel tabletop 1, and is a key component for realizing the "single-person operation" process.

[0023] The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
