Example 1

A household horizontal bar locking structure comprises a central tube 1, outer sleeves 2 rotatably arranged on two sides of the central tube 1, inner sleeves 5 slidably arranged in the outer sleeves 2, clamping feet 5 fixedly connected with the inner sleeves 5 and locking tubes 6 arranged in the central tube 1, wherein the locking tubes 6 are positioned in the outer sleeves 2;

the locking device comprises a central pipe 1, a locking bolt 3, a threaded pipe 7 and a locking pipe 6, wherein the central pipe 1 is provided with the locking bolt 3, the locking pipe 6 is fixedly provided with the threaded pipe 7, and the locking bolt 3 penetrates through the central pipe 1 to be in threaded connection with the threaded pipe 7 and is used for enabling the locking pipe 6 to be close to or far away from the locking bolt 3.

And the outer wall of the outer sleeve 2 is provided with threads, the screwing directions of the threads on the outer sleeve 2 are opposite, and the inner wall of the central tube 1 is also provided with threads matched with the threads on the inner sleeve 5. The user rotates the central tube 1, and the outer sleeves 2 on both sides of the central tube 1 can move away from or close to the central tube 1, so that the length of the horizontal bar can be adjusted.

The length of the locking pipe 6 is longer than that of the threads on the inner wall of the central pipe 1. In order to enable the locking pipe 6 to compress the outer sleeve 2, the length of the locking pipe 6 is longer than that of the thread on the inner wall of the central pipe 1, and the thread on the inner wall of the central pipe 1 is connected with the thread on the outer sleeve 2, so that the locking pipe 6 can compress the outer sleeve 2 only by enabling the length of the locking pipe 6 to be longer than that of the thread on the central pipe 1.

The locking bolt 3 is T-shaped, a plane 9 is arranged on the central tube 1, and the plane 9 is attached to one end face of the locking bolt 3. The T-shaped locking bolt 3 can be pressed against the flat surface 9, so that a movement of the locking tube 6 towards or away from the locking bolt 3 is achieved.

The central tube 1 is provided with a mounting hole 10, and the locking bolt 3 penetrates through the mounting hole 10 to be connected with the threaded tube 7. The surface of the locking bolt 3 is provided with anti-skid grains 8. The anti-slip threads 8 prevent slipping when the locking bolt 3 is rotated.

The working principle is as follows: when the length of the horizontal bar needs to be adjusted, the locking bolt 3 is rotated, so that a certain gap is formed between the end face of the locking bolt 3 and the plane 9 on the central tube 1. Then the central tube 1 is rotated, and the outer sleeve 2 extends out of or retracts into the central tube 1 by rotating in the same direction because the outer walls of the outer sleeve 2 on the two sides of the central tube 1 are provided with threads with opposite rotating directions. After the adjustment is completed, the locking bolt 3 is rotated, the locking pipe 6 is moved towards the locking bolt 3 until the locking bolt 3 cannot be rotated, at the moment, the locking pipe 6 tightly attaches the outer sleeve 2 to the inner wall of the central pipe 1, and finally the outer sleeve 2 cannot be rotated.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
