Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. 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.

Referring to fig. 1 to 6, in an embodiment of the present invention, a foldable home desk comprises a support 1, a desk plate 6 is disposed above the support 1, the bottom of the desk plate 6 is hinged to the top of the support 1 through a hinge, a plurality of second rotating members 61 are uniformly disposed at the bottom of the desk plate 6, two first movable grooves 11 are symmetrically disposed on outer walls on both sides of the support 1, two penetrating second movable grooves 12 are symmetrically disposed on the top of the support 1, a penetrating third movable groove 13 is disposed on the top of the support 1, first support legs 2 are rotatably connected to outer walls on both sides of the support 1 at one side of the first movable grooves 11, second support legs 3 are disposed in the second movable grooves 12, a threaded rod 4 is disposed on a side wall of the support 1, two ball bearings 41 are fixedly sleeved on outer walls of the threaded rod 4, the two ball bearings 41 are disposed inside the support 1 and fixedly connected to the support 1, two slide bars 43 of symmetry fixedly connected with in the third movable groove 13, the common sliding connection of outer wall of two slide bars 43 has slip table 5, the outer wall center department of slip table 5 runs through and is provided with threaded sleeve 51, threaded sleeve 51 passes through screw-thread fit with the screw thread portion of threaded rod 4 and is connected, the even fixedly connected with a plurality of first rotations 52 in top of slip table 5, the outer wall of first rotation 52 rotates and is connected with connecting rod 53, the one end of a plurality of connecting rods 53 rotates with the second rotation 61 that corresponds and is connected.

The threads of the threaded sleeve 51 and the threaded rod 4 are both trapezoidal threads, and the lead angle of the threads is smaller than the equivalent friction angle, so that the threaded rod 4 and the threaded sleeve 51 have self-locking performance.

The common fixedly connected with pivot 21 in outer wall middle part of two first landing legs 2, pivot 21 run through the outer wall middle part of two second landing legs 3, and two second landing legs 3 rotate with pivot 21 to be connected, but make first landing leg 2 and second landing leg 3 relative rotation through setting up of pivot 21, and cooperation second movable groove 12 has realized the folding of house table.

The outer wall of second landing leg 3 is close to top fixedly connected with gyro wheel 31, and two gyro wheels 31 are located the first movable groove 11 that corresponds, through the cooperation of gyro wheel 31 with first movable groove 11, can reduce the frictional force of house table when folding or expansion, make the operation laborsaving smooth more.

The end of the threaded rod 4, which is positioned outside the support 1, is fixedly sleeved with a plum blossom handle 42, and the plum blossom handle 42 is arranged to facilitate the rotation of the threaded rod 4.

In order to guarantee that there is good support to support 1 and table 6, a plurality of strengthening ribs 33 of the common even fixedly connected with of outer wall of two second landing legs 3, a plurality of strengthening ribs 33 can be with 3 fixed connection of two second landing legs, have promoted the stability of house table.

The utility model discloses a theory of operation is:

when the household table needs to be unfolded for use, the table board 6 is lifted upwards, the second supporting legs 3 are pulled at the same time, the rollers 31 fixedly connected with the two second supporting legs 3 are rolled to one end, far away from the first supporting leg 2, in the first movable groove 11, the first supporting leg 2 and the second supporting leg 3 are in an X shape, and due to the limitation of the rollers 31 and the first movable groove 11, the distance between the bottom ends of the first supporting leg 2 and the second supporting leg 3 reaches the maximum distance, so that the support 1 and the table board 6 can be stably and reliably supported (as shown in fig. 1); when the household table needs to be folded, the second supporting leg 3 is pushed to enable the roller 31 to move to one end, close to the first supporting leg 2, in the first movable groove 11, and at the moment, the first supporting leg 2 and the second supporting leg 3 are located on the same plane (as shown in fig. 6) with the support 1, so that the occupied space is small.

When the angle of the table plate 6 needs to be adjusted after the household table is placed, the quincuncial handle 42 is rotated to drive the threaded rod 4 to rotate, the sliding table 5 slides along the direction of the sliding rod 43 through the matching of the threaded rod 4 and the threaded sleeve 51 and the limiting effect of the sliding rod 43, then the table plate 6 starts to rotate by taking the hinged position of the table plate 6 and the support 1 as the circle center through the matching of the connecting rod 53, the first rotating piece 52 and the second rotating piece 61, and when the table plate 6 reaches a proper angle, the quincuncial handle 42 is stopped to rotate.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
