1-3, the present utility model provides a technical solution: a liftable table tennis table, including a table top 1, the top of the table top 1 is welded with uprights 2 at the center positions of the front and rear ends, and the right side of the bottom end of the table top 1 is welded. The rectangular box 3 is welded, the top of the inner cavity of the column 2 is axially connected with a screw 4 along the up-down direction, and the bottom end of the screw 4 extends to the inner cavity of the rectangular box 3, the inner side of the column 2 is provided with a through hole 5, and the outer wall of the screw 4 A threaded barrel 6 is threadedly connected, and the threaded barrel 6 is located at the bottom end of the inner cavity of the column 2. The threaded barrel 6 can move up and down on the outer top of the screw 4. The outer side of the inner cavity of the column 2 is provided with a chute 7 along the upper and lower directions. The bottom end of the inner cavity of 7 is clamped with a matching sliding block 8. The sliding block 8 can slide up and down in the inner cavity of the chute 7. The inner side of the sliding block 8 is welded with the threaded barrel 6, and the upward movement of the threaded barrel 6 can drive the sliding block. The block 8 moves upward at the same time, the inner side of the threaded barrel 6 is welded with a connecting rod 9, and the inner side of the connecting rod 9 extends out of the through hole 5. The upward movement of the connecting rod 9 can drive the ball net 10 to move upward, and the inner side of the connecting rod 9 is welded with a ball. The net 10, the bottom end of the screw 4 is welded with a first gear 11, the clockwise rotation of the second gear 13 can drive the first gear 11 to rotate counterclockwise, the inner cavity of the rectangular box 3 is axially connected with a first circular shaft 12 along the front and rear directions, The front and rear ends of the outer wall of the first round shaft 12 are interference-fitted with a second gear 13 that meshes with the first gear 11 . The clockwise rotation of the third gear 15 can drive the second gear 13 to rotate clockwise. The front side of the cavity is axially connected with a second round shaft 14 along the left and right direction, and the second round shaft 14 is located at the bottom end of the first round shaft 12, the right side of the second round shaft 14 extends out of the rectangular box 3, and the second round shaft 14 Clockwise rotation can drive the third gear 15 to rotate clockwise, the left side of the outer wall of the second round shaft 14 is fitted with a third gear 15 that meshes with the second gear 13, and the right side of the second round shaft 14 is welded with a handle 16. Table legs 17 are welded on the left and right sides of the bottom end of the desktop 1 .

As a preferred solution, further, the upper half of the outer wall of the screw 4 is provided with threads, and the lower half of the screw 4 has no threads. When the slider 8 moves to the bottom end of the inner cavity of the chute 7, the threaded barrel 6 is urged to move to the screw. 4. The bottom end of the outer wall thread to prevent the threaded barrel 6 from continuing to move.

As a preferred solution, further, the distance that the connecting rod 9 extends out of the through hole 5 is 1 cm, which reduces the space occupied by the connecting rod 9 and prevents the ball net from colliding with the column 2 when moving.

As a preferred solution, further, the diameter of the third gear 15 is smaller than the diameter of the second gear 13, which saves more effort when driving the second gear 13 to rotate, because the lever arm of the third gear 15 is smaller than the lever arm of the second gear 13, As a result, the power of the power point of the second and third gears 15 is greater than the resistance of the resistance point of the second gear 13, so labor is saved.

As a preferred solution, further, the height of the thread on the outer wall of the screw 4 is the same as the height of the inner side of the through hole 5 to ensure that when the threaded barrel 6 moves to the outer wall of the screw 4 and moves upward, the connecting rod 9 can normally move upward on the inner side of the through hole 5 .

The detailed connection means are known in the art. The following mainly introduces the working principle and process, and the specific work is as follows.

When in use, rotate the handle 16 clockwise by hand to make the second round shaft 14 rotate clockwise, and the third gear 15 rotates clockwise, driving the second gear 13 to rotate clockwise, and urges the first round shaft 12 to rotate clockwise to ensure The two second gears 13 rotate synchronously at the same time. The clockwise rotation of the second gear 13 drives the first gear 11 to rotate counterclockwise, which causes the screw 4 to rotate counterclockwise, which drives the threaded barrel 6 to move upward on the outer wall of the screw 4, while the slider 8 is at the same time. The inner cavity of the chute 7 slides upward, driving the connecting rod 9 to move upward at the same time on the inside of the through hole 5, prompting the ball net 10 to move upward, raising the ball net 10, and rotating the handle 16 counterclockwise by hand to promote the second round shaft 14 rotates counterclockwise, the third gear 15 rotates counterclockwise, drives the second gear 13 to rotate counterclockwise, and drives the first circular shaft 12 to rotate counterclockwise to ensure that the two second gears 13 rotate synchronously at the same time, and the second gear 13 rotates counterclockwise The rotation drives the first gear 11 to rotate clockwise, which drives the screw 4 to rotate clockwise, which drives the threaded barrel 6 to move down on the outer wall of the screw 4, and at the same time, the slider 8 slides down in the inner cavity of the chute 7, which drives the connecting rod 9 to move downward. The inner side of the through hole 5 moves downward at the same time, which urges the net 10 to move downward, lowers the net 10, is convenient to use, can quickly change the height of the net 10, does not need to replace the net 10, reduces the production cost, and is beneficial to the device promotion and use.
