Description

Technical Field

[0001] The utility model relates to the technical field of folding tables, in particular to a four-legged folding table. Background Art

[0002] A folding table is a table with a folding function. It is generally made of steel and wood and is easy to fold and transport. However, since the four-legged folding table itself is a square structure, and the size of the tabletop can only be expanded after it is opened, and the expanded tabletop is fixed, it is not convenient to adjust according to needs, resulting in a relatively single functionality of the four-legged folding table. To this end, we propose a four-legged folding table. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a four-legged folding table.

[0004] The technical solution adopted by the utility model to solve the technical problem is a four-legged folding table, comprising a folding table body, a support is assembled in the folding table body, and a vertical cylinder is slidably installed in the support, a screw connected with the vertical cylinder is rotatably installed in the support, and a worm wheel is sleeved and installed on the outer periphery of the screw, a worm connected with the worm wheel is rotatably installed in the support, a groove is opened on the top surface of the folding table body, and a table board matching the groove is rotatably installed on the top surface of the vertical cylinder, and a rotating seat connected with the worm is rotatably installed on the outer wall surface of the support;

[0005] A frame is installed on one side of the table top close to the groove, and there are two groups of frames. A slide is slidably installed in the frame, and a spring hinge is installed on the outer wall surface of the slide, and there are multiple groups of spring hinges. The end of the spring hinge away from the slide is equipped with a sub-table top located at the bottom of the table top, and the bottom end surface of the table top is equipped with bull's eye wheels that abut against the sub-table top, and there are multiple groups of bull's eye wheels.

[0006] By adopting the above technical scheme, when the four-legged folding table is in use, the tabletop of the folding table body can be expanded by utilizing its own telescopic structure, and at the same time, the rotating seat on the surface of the support inside the folding table body can be rotated, and the rotating seat is convenient for driving the worm inside the support to rotate, so that the worm and the worm wheel disc are meshed with each other and drive the worm wheel disc to rotate, and then the worm wheel disc conveniently drives the screw to rotate, so that the vertical cylinder slidably installed in the support can be screwed with the screw rod and the vertical cylinder is extended from the top of the support, and at the same time, it is convenient to drive the table plate and the groove on the surface of the folding table body to separate from each other, and the reverse operation is convenient for storing the table plate, so that the tabletop of the four-legged folding table is convenient for adjusting;

[0007] When the tabletop is separated from the groove, two sets of auxiliary tableboards at the bottom of the tabletop can be pulled, so that the auxiliary tableboards pull the sliding plates in the frame through the spring hinges, and with the sliding support of the bull's-eye wheels at the bottom of the tabletop, the auxiliary tableboards can extend more smoothly. Subsequently, under the action of the spring hinges between the sliding plates and the auxiliary tableboards, the auxiliary tableboards can swing and displace, and one end of the auxiliary tableboards can abut and fit against the outer wall surface of the tabletop, making the structure of the tabletop circular and convenient for use. Thus, the tabletop of the four-legged folding table can not only be expanded, but also has the effect of a circular tabletop, and the circular tabletop is convenient for telescopic storage and use.

[0008] Specifically, a ring groove is formed on the top surface of the support, and a ring body that fits with the ring groove is integrally formed on the outer peripheral surface of the vertical cylinder. An arc groove is formed on the inner peripheral surface of the ring body, and there are multiple groups of arc grooves. An arc block that fits with the arc groove is integrally formed on the inner peripheral surface of the ring groove, and there are multiple groups of arc blocks. A ring body for limiting is assembled at one end of the ring body located in the ring groove.

[0009] By adopting the above technical solution, the ring body and the ring groove fit with each other. At the same time, the arc block in the ring groove and the arc groove on the inner periphery of the ring body fit with each other, and with the blocking of the ring body, it is convenient for limiting, so that when the vertical cylinder extends out of the support, the situation of separation will not occur.

[0010] Specifically, glue blocks that abut against the auxiliary tableboards are bonded to the bottom surface of the tabletop, and there are multiple groups of glue blocks.

[0011] By adopting the above technical solution, the glue blocks have good elasticity, which is convenient for reducing the abrasion damage caused by scratches on the bottom of the auxiliary tableboard and the tabletop, and can assist in supporting the retracted auxiliary tableboard.

[0012] Specifically, two sliding holes are formed on the inner wall surface of the frame, and sliding blocks that are slidably connected to the sliding holes are assembled on the bottom surface of the sliding plate.

[0013] By adopting the above technical solution, the sliding blocks and the sliding holes are slidably connected to each other, which is convenient for limiting the sliding of the sliding plate in the frame, thereby reducing the situation of separation between the sliding plate and the frame.

[0014] Specifically, a screw hole is formed on the top surface of the vertical cylinder, and an inner hexagon screw column that is screwed and connected to the screw hole is screwed and installed on the top surface of the tabletop.

[0015] By adopting the above technical solution, rotate the inner hexagon screw column on the surface of the tabletop, so that the part at the bottom of the inner hexagon screw column is screwed and separated from the screw hole at the top of the vertical cylinder, thereby releasing the lock on the tabletop rotatably installed at the top of the vertical cylinder. Subsequently, the tabletop can be rotated for convenient use.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application, through the design of the support, vertical cylinder, worm gear, worm, screw, groove, table top and swivel seat, can expand the table top of the folding table body by utilizing its own telescopic structure when the four-legged folding table is in use, and can also rotate the swivel seat on the surface of the support inside the folding table body, so that the swivel seat can easily drive the worm inside the support to rotate, so that the worm and the worm gear disc mesh with each other and drive the worm gear disc to rotate, and then the worm gear disc can easily drive the screw to rotate, so that the vertical cylinder slidably installed in the support can be screwed with the screw rod and the vertical cylinder can extend from the top of the support, and at the same time, it is convenient to drive the table top and the groove on the surface of the folding table body to separate from each other, and the reverse operation is convenient for storing the table top, thereby facilitating the adjustment of the table top of the four-legged folding table.

[0018] 2. The technical solution of the present application is designed with a frame, a slide plate, a spring hinge, a sub-table plate and a bull's eye wheel. When the table top and the groove are separated from each other, the two groups of sub-table plates at the bottom of the table top can be pulled, so that the sub-table plate pulls the slide plate in the frame through the spring hinge, and the sub-table plate can be extended more smoothly under the sliding support of the bull's eye wheel at the bottom of the table top. Then, under the action of the spring hinge between the slide plate and the sub-table plate, the sub-table plate can be swung and displaced, and one end of the sub-table plate can be abutted and fit against the outer wall surface of the table top, so that the structure of the table top becomes round, which is convenient for its use. Therefore, the table top of the four-legged folding table can not only be expanded, but also has the effect of a round table top, and the round table top is convenient for telescopic storage and easy to use.
