Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 4, the present invention provides a folding table, which comprises a table top 1 and a supporting structure located under the table top 1, wherein the supporting structure comprises a supporting frame 2 and a turning frame 3. The turnover frame 3 and the support frame 2 support the table top 1 during folding or unfolding after being turned along the turning central shaft.

The supporting frame 2 is an I-shaped structure and comprises a central rod 201 parallel to the central axis of the turnover, and the central rod 201 is tightly attached to the tabletop 1. Two parallel horizontal support rods 202 which are also tightly attached to the tabletop 1 are arranged on the left side and the right side perpendicular to the central rod 201. All articulated on two horizontal support rods 202 that are located well core rod 201 one side have first leg support rod 4, and the lower extreme of first leg support rod 4 is provided with gyro wheel 5. The rollers 5 can make the desktop move anywhere whether the desktop is unfolded or folded. And a first cross bar 6 is connected between the two first leg support bars 4.

The roll-over stand 3 is hinged to one side of the central rod 201 and comprises a roll-over rod 301 parallel to the central rod 201, two roll-over support rods 302 parallel to each other are arranged on one side perpendicular to the roll-over rod 301, and the roll-over support rods 302 are locked with the adjacent horizontal support rods 202 which are positioned on the same side of the central rod 201 through locking pieces 14 after being unfolded. All articulated on two upset bracing pieces 302 have second shank bracing piece 7, and are connected with second horizontal pole 8 between two second shank bracing pieces 7. Two groups of connecting rod assemblies 9 used for opening or closing the first cross rod 6 and the second cross rod 8 are further arranged below the table top 1. A jacking mechanism 10 for lifting the table top 1 is also arranged below the table top 1.

The table is unfolded and folded in the following manner: when the table needs to be unfolded, the two first leg support rods 4 at the two ends of the first cross rod 6 are firstly spread on the ground, the two mutually parallel turnover support rods 302 are turned over to the lower part of the table top 1 along the turnover rod 301, and the turnover support rod 302 at one side is locked with the horizontal support rod 202 adjacent to the turnover support rod 302 through the locking piece 14. Then the second leg support rods 7 at the two ends of the second cross rod 8 are spread to support the table top 1 together with the first leg support rods 4. Because two sets of link assembly 9 are intercrossing's structure, at the in-process that desktop 1 rises gradually, provide horizontal holding power to first horizontal pole 6 and second horizontal pole 8, improve desktop horizontal direction's stability. Due to the jacking function of the jacking mechanism 10 on the table top 1, the longitudinal direction of the table is kept stable, so that the stability of the whole table after being unfolded is improved;

when the table needs to be folded, the steps are reversed, and finally the turning support bar 302 is turned downwards along the turning bar 301. Compare in the shank bracing piece support ground of one side in the past, the utility model discloses a first shank bracing piece 4 and second shank bracing piece 7 support in ground simultaneously, have improved the stability of folding whole desk.

As a preferred embodiment: the connecting rod assembly 9 comprises a first connecting rod 901 and a second connecting rod 902, and two ends of the first connecting rod 901 are respectively hinged on the first cross rod 6 and the turnover rod 301; the two ends of the second connecting rod 902 are respectively hinged on the second cross rod 8 and the central rod 201. The first connecting rod 901 and the second connecting rod 902 which are arranged in a crossed manner can enable the table to be unfolded and have a transverse supporting force between the first cross rod 6 and the second cross rod 8, and enable the overturning supporting rod 302 to stably overturn downwards when the table is folded, so that the table top 1 cannot rapidly fall back under the action of gravity, an arm cannot be inadvertently clamped, or a table component cannot be damaged.

Preferably, the jacking mechanism 10 comprises a jacking sleeve 102 crosswise hinged to the lower ends of the central rod 201 and the turning rod 301 through a third connecting rod 101, a jacking rod 103 is sleeved inside the jacking sleeve 102, a fourth connecting rod 104 and a fifth connecting rod 105 are hinged to the bottom of the jacking rod 103, and the top ends of the fourth connecting rod 104 and the fifth connecting rod 105 are respectively hinged to the side edges of the central rod 201 and the turning rod 301. When the table needs to be unfolded, the hinged positions of the central rod 201 and the turnover rod 301 and the fourth connecting rod 104 and the fifth connecting rod 105 are gradually far away, so that the top rod 103 hinged to the bottom ends of the fourth connecting rod 104 and the fifth connecting rod 105 rises inside the jacking sleeve 102 to support the lower part of the table top 1, and the longitudinal direction of the table is kept stable.

To further improve the stability of the table, the first leg support bar 4 and the second leg support bar 7 each include a vertical bar 11. The vertical rod 11 is inclined outward gradually from top to bottom. A horizontal supporting leg 12 is arranged above the bottom of the vertical rod 11, and the horizontal supporting leg 12 can increase the bearing area of the leg supporting rod. While the roller 5 is mounted below the horizontal leg 12, the vertical rod 11 and the bottom end of the roller 5 are located on the same horizontal support surface. The vertical rod 11 and the bottom ends of the rollers 5 are in contact with the ground together, so that the stability of the table is improved.

The two turning support rods 302 and the two horizontal support rods 202 on one side of the central rod 201 are positioned on the same straight line, so that the bottom of the table top 1 is uniformly stressed. And are connected by a hinge 13. The hinge 13 includes two hinge plates (not shown in the drawings) hinged to each other and capable of being turned to a horizontal position, and the two hinge plates are respectively mounted on the turning support bar 302 and the horizontal support bar 202 which are located in the same line after being unfolded. The hinge 13 may allow the flipping of the flipping bar 301 relative to the central bar 201 to be more gradual. The two horizontal support bars 202 on the other side of the center bar 201 are located outside the turning support bars 302.

The four leg supporting rods below the folded seat surface of the utility model simultaneously support the table top 1, and the table can be freely moved according to the requirement, thereby improving the stability of the folded table; the table legs are transversely pulled up by the aid of the connecting rod assemblies 9 arranged in a crossed mode, the table top 1 is longitudinally pulled up by the aid of the jacking mechanisms 10, and stability of the unfolded table is improved.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
