Description

Technical Field

[0001] This utility model relates to the field of furniture technology, specifically to a folding table. Background Technology

[0002] Traditional tables have a fixed size, occupy a lot of space, and are not easy to transport and use. The emergence of folding tables has alleviated the space occupation problem to some extent, but the folding tables on the market still have many defects in terms of function and performance. For example, Chinese utility model patent application number 201920825272.3 discloses a folding table, including a middle sub-table and outer sub-tables rotatably connected to both sides of the middle sub-table. A first leg is fixedly connected to the bottom of the middle sub-table, and a second leg and a third leg are rotatably connected to both sides of the first leg. The outer sub-table can be unfolded and folded by the rotation support of the second and third legs. This folding table has a simple structure, is easy to unfold and fold, and is not easily damaged; at the same time, the support plate located at the lower end of the first leg makes the folding table of this utility model easy to place.

[0003] However, during use, it was found that when the folding table is unfolded, if the second and third legs are not positioned in the center of the outer sub-tablet, heavy items placed on the outer sub-tablet can easily cause it to fold automatically, potentially injuring the user. Even if the second and third legs are correctly positioned, the user may still accidentally kick one or both legs. Since there is no corresponding restraint structure between the second and third legs and the outer sub-tablet, this can also cause the folding table to fold, resulting in injury to the user.

[0004] In addition, when folding tables are used for a long time, the outer side panels on both sides tend to sag, causing the outer side panels to form a slope away from the middle side panel. When items are placed on the table, they will slide along the slope, which can easily cause the items to fall off the table and break, or even pose a safety hazard of injuring the user. Utility Model Content

[0005] This utility model provides a folding table with a simple structure, convenient operation and not easy to damage. It can not only prevent accidental folding and injury through the positioning part, but also the height of the support is adjustable, which can prevent the secondary table board from tilting away from the main table board during long-term use.

[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] like Figures 1 to 11As shown in the figure, a folding table includes a tabletop and table legs. The tabletop is circular. The circular tabletop includes a main tabletop 1 and auxiliary tabletops located on both sides of the main tabletop 1. The auxiliary tabletops include a first auxiliary tabletop 2 located to the left of the main tabletop 1 and a second auxiliary tabletop 21 located to the right of the main tabletop 1. Both the first auxiliary tabletop 2 and the second auxiliary tabletop 21 have an arc-shaped structure, and both are rotatably connected to the main tabletop 1 via hinges 22. The rotation axes of both the first auxiliary tabletop 2 and the second auxiliary tabletop 21 extend along the length direction of the main tabletop 1, so that both the first auxiliary tabletop 2 and the second auxiliary tabletop 21 can be flipped downwards from the main tabletop 1.

[0032] The table legs include vertically arranged main legs 3 and secondary legs, both formed by welding together several rectangular tubes. The length direction of the main legs 3 is the same as that of the main tabletop 1. The main legs 3 include two vertically symmetrical main leg units 31. Each main leg unit 31 includes an upper edge 311 and a lower edge 313, which are welded together. One end of the upper edge 311 is welded to a crossbeam 312, which is bolted to both ends of the main tabletop 1. The upper edge 311 is inclined towards the center of the main tabletop 1, and the upper edge 311 and the lower edge 313 are symmetrical about the horizontal direction. To strengthen the two main leg units 31, a first reinforcing rib 317 is welded between them.

[0033] The secondary table legs include a first secondary table leg 41 and a second secondary table leg 42. The first secondary table leg 41 and the second secondary table leg 42 are rotatably connected to both sides of the main table leg 3 along its length, and the rotation axes of the first secondary table leg 41 and the second secondary table leg 42 both extend in the vertical direction. In this embodiment, the first secondary table leg 41 and the second secondary table leg 42 have the same structure and are symmetrically distributed about the main table leg 3. Both the first secondary table leg 41 and the second secondary table leg 42 include a secondary table leg unit 421, which includes an upper secondary ridge 422 and a lower secondary ridge 423. The upper secondary ridge 422 and the lower secondary ridge 423 are welded together, and a first connecting part 424 is connected between the upper secondary ridge 422 and the lower secondary ridge 423. The first connecting part 424 is a horizontally arranged rectangular tube, one end of which is welded between the upper secondary ridge 422 and the lower secondary ridge 423, and the other end is rotatably connected to the middle position of the first reinforcing rib 317. Specifically, a first rotating plate 318 is welded perpendicularly to the upper and lower surfaces of the first reinforcing rib 317 at the middle position. Both ends of the first rotating plate 318 extend beyond the sides of the first reinforcing rib 317 and are provided with first mounting through holes 319 at both ends. A first connecting part 424 is sandwiched between the two first rotating plates 318 and is provided with a first connecting hole 425 at the position corresponding to the first mounting through hole 319. A shaft pin passes through the first mounting through hole 319 and the first connecting hole 425 to realize the rotational connection between the first connecting part 424 and the first reinforcing rib 317, that is, to realize the rotational connection between the first secondary table leg 41 and the second secondary table leg 42 and the main table leg 3.

[0034] In a preferred embodiment, the main table leg unit 31 further includes a first vertical rod 316 vertically welded between the upper edge 311 and the lower edge 313, and a first reinforcing rib 317 welded between the top ends of the two first vertical rods 316. The first reinforcing rib 317 is horizontally arranged to enhance the strength between the two main table leg units 31. A second reinforcing rib 320 is welded between the bottom ends of the two first vertical rods 316, and the second reinforcing rib 320 is parallel to the first reinforcing rib 317. The secondary table leg unit 421 further includes a second vertical rod 428 welded between the upper secondary edge 422 and the lower secondary edge 423. A first connecting portion 424 is disposed at the top end of the second vertical rod 428, and a second connecting portion 426 is welded to the bottom end of the second vertical rod 428. The second connecting portion 426 is also a horizontally arranged rectangular tube. One end of the rectangular tube is welded between the second vertical rod 428 and the lower secondary edge 423, and the other end is rotatably connected to the middle position of the second reinforcing rib 320. The upper and lower surfaces of the second reinforcing rib 320 are welded perpendicularly to the second reinforcing rib 320. The two ends of the second rotating plate 321 extend beyond the two sides of the second reinforcing rib 320 and are provided with second mounting through holes 322 at both ends. The second connecting part 426 is sandwiched between the two second rotating plates 321 and is provided with a second connecting hole 427 at the position corresponding to the second mounting through hole 322. The shaft pin passes through the second mounting through hole 322 and the second connecting hole 427 to realize the rotational connection between the second connecting part 426 and the second reinforcing rib 320, that is, to realize the rotational connection between the first secondary table leg 41 and the second secondary table leg 42 and the main table leg 3.

[0035] A placement hole 11 is provided in the middle of the main table panel 1. The placement hole 11 is used to place a heating device, which can be a steam pot, a charcoal grill, an electric ceramic stove or an induction cooker, to facilitate heating the hot pot and make this folding table more practical.

[0036] This utility model's folding table has two states: an unfolded state and a folded state. When the folding table is in the folded state, the first auxiliary table leg 41 and the second auxiliary table leg 42 rotate to a position parallel to the main table leg 3. The first auxiliary tabletop 2 and the second auxiliary tabletop 21 disengage from their supports and flip downwards to a position perpendicular to the main tabletop 1. At this time, a receiving groove is formed between the first auxiliary tabletop 2, the second auxiliary tabletop 21, and the main tabletop 1, with the lower wall surface of the main tabletop as the groove bottom. The first auxiliary table leg 41, the second auxiliary table leg 42, and the main table leg 3 are all located within the receiving groove. When the folding table is in the unfolded state, the first auxiliary tabletop 2 and the second auxiliary tabletop 21 are joined with the main tabletop 1 to form a circular tabletop. The first auxiliary table leg 41 and the second auxiliary table leg 42 unfold to a position perpendicular to the main table leg 3. The first auxiliary leg supports the first auxiliary tabletop 2, and the second auxiliary leg supports the second auxiliary tabletop 21.

[0037] Positioning parts are provided between the first table leg 41 and the first tabletop 2, and between the second table leg 42 and the second tabletop 21. When the folding table is unfolded, the positioning parts can lock the positions of the first tabletop 2 and the first table leg 41, and the second tabletop 21 and the second table leg 42, to prevent the folding table from accidentally folding and causing injury to the user due to placing heavy objects on the first tabletop 2 or the second tabletop 21, or if the user accidentally kicks the first table leg 41 or the second table leg 42, thus improving the safety of use.

[0038] The positioning part includes a positioning hole 51 formed on the lower surface of the first sub-tabletop 2 or the second sub-tabletop 21, and a positioning element 52 located at the top of the first sub-table leg 41 or the second sub-table leg 42 and corresponding to the positioning hole 51. The positioning hole 51 is a blind hole. The positioning element 52 includes a first mounting sleeve 53 and a second mounting sleeve 54 fixedly connected to the top of the first sub-table leg 41 or the second sub-table leg 42. The first mounting sleeve 53 and the second mounting sleeve 54 are vertically arranged and spaced apart. A locking rod 55 is inserted inside the first mounting sleeve 53 and the second mounting sleeve 54. The outer diameter of the locking rod 55 matches the inner diameter of the first mounting sleeve 53 and the second mounting sleeve 54. The locking rod 55 is provided with a blocking part 56, which is located between the first mounting sleeve 53 and the second mounting sleeve 54. When the top of the blocking part 56 abuts against the lower surface of the first mounting sleeve 53, the locking rod 55 can protrude from the upper surface of the first mounting sleeve 53 and be inserted into the positioning hole 51. A return spring 57 is sleeved around the locking rod 55, and a blocking part 56 is positioned above the return spring 57. Under the action of the return spring 57, the blocking part 56 always abuts against the first mounting sleeve 53, so that the locking rod 55 is inserted into the positioning hole 51, thereby fixing the unfolded position of the folding table. At this time, the positions of the first tabletop 2 and the first table leg 41, and the second tabletop 21 and the second table leg 42 are locked.

[0039] When using the table, users simply need to rotate the first and second legs 41 and 42 normally. When the first and second legs 41 and 42 are rotated to the unfolded position perpendicular to the main leg 3, the locking rod 55 will automatically and accurately insert into the positioning hole 51 under the elastic force of the return spring 57, quickly completing the fixation without any complicated operation by the user. When the table needs to be folded, the user only needs to push the locking rod 55 downwards to allow it to smoothly disengage from the positioning hole 51, thus achieving the folding operation. This not only improves the convenience of using the folding table but also makes daily use and storage easier and more efficient, bringing a better user experience.

[0040] In a preferred embodiment, a support member 6 is provided at the top of both the first auxiliary table leg 41 and the second auxiliary table leg 42. The support member 6 includes a support screw 61 and a support block 62 fixedly connected to the top of the support screw 61. Bolt mounting holes are provided at the top of both the first auxiliary table leg 41 and the second auxiliary table leg 42, and the support screw 61 is screwed into the bolt mounting holes to adjust the height of the support member 6. The user can raise the height of the support member 6 as needed to prevent the first auxiliary tabletop 2 and the second auxiliary tabletop 21 of the folding table from tilting away from the main tabletop 1 during prolonged use of the folding table, thereby preventing items on the table from slipping off.

[0041] In a preferred embodiment, a support plate 314 is welded to the bottom of the lower edge 313. The support plate 314 extends along the width direction of the main table leg 3 to both sides of the main table leg 3 to support the folding table. Two casters 315 are connected to the bottom of the support plate 314, and the two casters 315 are located at both ends of the support plate 314 to facilitate the movement of the folding table. Casters 315 are also fixedly connected to the bottom of the lower secondary edge 423 to facilitate the folding and unfolding of the first secondary table leg 41 and the second table leg. The casters 315 can be casters with a brake structure to prevent the folding table from moving during use.

[0042] When this folding table is unfolded: First, unlock the brake mechanism of caster 315, move the folding table to a suitable position, and rotate the first auxiliary table leg 41 and the second auxiliary table leg 42 to be perpendicular to the main table leg 3. When both the first auxiliary table leg 41 and the second auxiliary table leg 42 are rotated to be perpendicular to the main table leg 3, the locking rod 55 is aligned with the positioning hole 51. At this time, the locking rod 55 is inserted into the positioning hole 51 under the elastic force of the return spring 57, realizing the locking of the first auxiliary table leg 41 with the first auxiliary table board 2, and the locking of the second auxiliary table leg 42 with the second auxiliary table board 21. At this time, rotate the support member 6 as needed to adjust the height of the support member 6 to prevent the first auxiliary table board 2 and the second auxiliary table board 21 from tilting away from the main table board 1 after long-term use. Finally, use the brake mechanism to fix the caster 315 to prevent the folding table from moving.

[0043] When folding this folding table after use: First, push the latching lever 55 downwards to disengage it from the positioning hole 51. Then, rotate the first table leg 41 and the second table leg 42 until they are parallel to the main table leg 3. At this time, the first tabletop 2 and the second tabletop 21 lose their support and flip downwards to a position perpendicular to the main tabletop 1. This completes the folding and storage of the table. Finally, unlock the brake mechanism of the caster 315 and move the folding table to a convenient location.

[0044] This embodiment is merely an illustration of the concept and implementation of this utility model, and is not intended to limit it. Under the concept of this utility model, the technical solution without substantial changes is still within the protection scope.
