Description
Technical Field
[0001] The utility model relates to the technical field of folding tables, and particularly relates to a high-stability folding table. Background Art
[0002] A folding table is a table that can reduce its volume by folding. The design of the folding table enables it to reduce its volume by folding when not in use, thus facilitating storage and carrying. It not only saves space but also is convenient to move, so it is very suitable for use in families, offices, and public places.
[0003] However, when the existing high-stability folding table is in use, usually when opening the folding table, the extension board inside the folding table needs to be taken out from the table board, and then the legs of the folding table are adjusted to make the folding table in an open state. At the same time, when folding the folding table, the extension board needs to be put into the table board in sequence, and then the position of the legs is adjusted to make the folding table in a folded state. The operation steps are cumbersome, and it is impossible to operate the legs of the folding table while operating the extension board of the folding table. The opening and folding time of the folding table is relatively long, and there is no limit between the legs, which has a certain impact on the stability of the folding table. Therefore, a high-stability folding table is provided. Content of the Utility Model
[0004] The main purpose of the utility model is to provide a high-stability folding table. By setting the driving block A, driving block B, bidirectional threaded rod, fixed frame, transmission frame A, transmission frame B, threaded sleeve A, and threaded sleeve B, the utility model solves the problem that when the existing high-stability folding table is in use, it is impossible to operate the legs of the folding table while operating the extension board of the folding table, and the opening and folding operation time of the folding table is relatively long.
[0005] The technical solution adopted by the present utility model to solve its technical problems is a highly stable folding table, including a tabletop and a fixed block. The bottom of the tabletop is fixed with a fixing frame that supports the tabletop by screws. A handle is inserted outside the fixing frame, and a bidirectional threaded rod is fixed by screws on one side of the handle. Threaded sleeve A and threaded sleeve B are threadedly connected to the outside of the bidirectional threaded rod, and threaded sleeve A is located on the left side of threaded sleeve B. A transmission frame A that moves horizontally is welded to the outside of threaded sleeve A. A driving block A is fixed by screws on the top outside the transmission frame A, and an extension plate A that extends the length of the tabletop is welded to the outside of the driving block A. A transmission frame B that moves horizontally is welded to the outside of threaded sleeve B. A driving block B is fixed by screws on the top end outside the transmission frame B, and an extension plate B that extends the length of the tabletop is welded to the outside of the driving block B. A support plate A is fixed by screws on the bottom outside the transmission frame A, and a bracket that supports the fixing frame is rotatably connected inside the support plate A. The extension of the bracket away from the support plate A extends into the fixed block. A support plate B is fixed by screws on the bottom end outside the transmission frame B, and a telescopic frame is rotatably connected inside the inner side of the support plate B. One end of the telescopic frame away from the support plate B extends into the fixed block, and both the bracket and the telescopic frame are rotatably connected to the inner side of the fixed block. Leg A and leg B that support the tabletop are symmetrically rotatably connected to the outside of the fixed block, and leg A is located on the left side of leg B. A rope chain is fixed by screws on the outside of leg B, and a limit hook connected to leg A is welded to one end of the rope chain away from leg B. A ring block that fixes the limit hook is welded to the outside of leg A. Rubber sleeves that increase the friction with the ground are adhered to the bottom ends of both leg A and leg B.
[0006] By adopting the above technical solution, when the folding table needs to be opened, rotate the handle on the fixing frame at the bottom of the tabletop. The handle drives the bidirectional threaded rod inside the fixing frame to rotate. Threaded sleeve A and threaded sleeve B outside the bidirectional threaded rod move horizontally outside the bidirectional threaded rod. Then, the transmission frame A outside threaded sleeve A drives the external driving block A and support plate A to move. Subsequently, the driving block A drives the extension plate A to move, and the bracket inside the support plate A rotates inside the support plate A and the fixed block. At the same time, threaded sleeve B drives the driving block B and support plate B outside the transmission frame B to move. Subsequently, the driving block B drives the extension plate B to move, and the bracket inside the support plate B rotates inside the support plate B and the fixed block. Then, pull leg A and leg B to rotate inside the fixed block to support the tabletop, so as to support the tabletop while unfolding the tabletop, which is convenient for operation and achieves the purpose of saving time.
[0007] When leg A and leg B come into contact with the ground, pull the rope chain on leg B so that the limit hook at one end of the rope chain is connected to the ring block on leg A, so as to limit leg A and leg B. At the same time, the rubber sleeves at the bottoms of leg A and leg B increase the friction with the ground, thereby improving the stability of the folding table.
[0008] A bearing sleeve is provided at the connection between the handle and the fixed frame, making the rotation of the handle driving the bidirectional threaded rod stable. And a bearing seat is provided at the connection between the bidirectional threaded rod and the fixed frame, making the rotation of the bidirectional threaded rod stable.
[0009] When the folding table needs to be folded, rotate the handle outside the fixed frame. The handle drives the bidirectional threaded rod to rotate. The thread sleeves A and B outside the bidirectional threaded rod drive the transmission frames A and B to move respectively. The transmission block A drives the support plate A and the drive block A to move. The drive block A drives the extension plate A into the tabletop. The bracket in the support plate A rotates. The transmission block B drives the support plate B and the drive block B to move. The drive block B drives the extension plate B into the tabletop. The telescopic frame in the support plate B rotates. Then pull the bracket and the telescopic frame to rotate to the left. The telescopic frame starts to extend. The telescopic frame and the bracket move into the tabletop. Subsequently, pull the legs A and B in the fixed frame to rotate, thus facilitating the folding process of the folding table.
[0010] Specifically, ball bearings are provided inside both the drive block A and the drive block B, and sliding grooves for the ball bearings to roll are provided on the inner side of the tabletop.
[0011] By adopting the above technical solution, when the drive block A drives the extension plate A and the drive block B drives the extension plate B to move, the ball bearings on the drive block A and the drive block B roll in the sliding grooves opened in the tabletop respectively, thereby improving the stability of the movement of the extension plate A and the extension plate B in the tabletop.
[0012] Specifically, slider sleeves for limiting the thread sleeves A and B are symmetrically welded outside both the thread sleeve A and the thread sleeve B, and slide bars for the slider sleeves to slide are welded inside the fixed frame.
[0013] By adopting the above technical solution, when the thread sleeves A and B move outside the bidirectional threaded rod, the slider sleeves outside the thread sleeves A and B slide outside the slide bars respectively, limiting the thread sleeves A and B and improving the stability of the lateral movement of the thread sleeves A and B outside the bidirectional threaded rod.
[0014] Specifically, fixed sleeves are symmetrically welded outside both the transmission frame A and the transmission frame B, and support rods for making the movement of the transmission frames A and B stable are slidably connected inside the fixed sleeves.
[0015] By adopting the above technical solution, when the transmission frames A and B move inside the fixed frame, the fixed sleeves outside the transmission frames A and B slide outside the support rods respectively, improving the stability of the movement of the transmission frames A and B.
[0016] Specifically, lubricating oil for making the legs A, legs B, bracket and telescopic frame rotate flexibly is applied inside the fixed block.
[0017] By adopting the above technical solution, a protective film is formed on one side inside the fixed block by applying lubricating oil inside the fixed block, preventing the inside of the fixed block from rusting and facilitating the flexible rotation of leg A, leg B, the bracket, and the telescopic frame.

Then, the transmission frame A outside the threaded sleeve A drives the external drive block A and the support plate A to move. Subsequently, the drive block A drives the extension plate A to move.

At the same time, the threaded sleeve B drives the drive block B and the support plate B outside the transmission frame B to move. Subsequently, the drive block B drives the extension plate B to move. The bracket inside the support plate B rotates inside the support plate B and the fixed block.

Subsequently, the drive block B17 drives the extension plate B2 to move. The bracket 5 inside the support plate B25 rotates inside the support plate B25 and the fixing block 11. Then the legs A7 and the legs B12 are pulled to rotate inside the fixing block 11 to support the table top plate 3, thereby supporting the table top plate 3 while unfolding the table top plate 3, which is convenient for operation and achieves the purpose of saving time;
[0042] When the outrigger A7 and the outrigger B12 are in contact with the ground, pull the chain 9 on the outrigger B12, so that the limit hook 8 at one end of the chain 9 is connected to the ring block 6 on the outrigger A7, so as to limit the outrigger A7 and the outrigger B12.
