It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.

As shown in fig. 1 to 4, an adjustable horizontal bar comprises a first side upright 1, a second side upright 2 and a movable bar 3, wherein the top of the first side upright 1 is connected with the top of the second side upright 2 through a push rod 8, a plurality of first limit grooves 11 are formed in the first side upright 1, a plurality of second limit grooves 21 opposite to the first limit grooves 11 are formed in the second side upright 2, and the first limit grooves 11 and the second limit grooves 21 are in one-to-one correspondence. The first side upright post 1 is of a hollowed sandwich structure and comprises two first side upright plates 12 which are distributed oppositely, a plurality of first sandwich crosspieces 13 are connected between the two first side upright plates 12, and any two adjacent first limit grooves 11 are separated by the first sandwich crosspieces 13; the second side upright post 2 is also of a hollowed sandwich structure and comprises two second side upright plates 22 which are distributed oppositely, a plurality of second sandwich crosspieces 23 are connected between the two second side upright plates 22, and any two adjacent second limiting grooves 21 are separated by the second sandwich crosspieces 23.

One end of the movable bar 3 is provided with a first tenon 31, the other end is provided with a second tenon 32, the first tenon 31 and the second tenon 32 are flat heads, and the length of the first tenon 31 is larger than that of the second tenon 32. After the first tenon 31 is inserted into the first limit groove 11, the movable bar 3 is moved, the second tenon 32 can be inserted into the corresponding second limit groove 21, and the second tenon 32 can be moved from the upper portion to the bottom portion of the corresponding second limit groove 21. In order to prevent the movable bar 3 from rotating when in use, the movable bar 3 has the biggest characteristics that two ends are made into flat tenons, and the movable bar 3 can be prevented from rotating after the first tenons 31 and the second tenons 32 are inserted into corresponding limit grooves.

A first avoiding inclined plane 14 is arranged on the inner side of the first sandwich crosspiece 13, so that the first tenon 31 is convenient to install; the second avoidance inclined plane 24 is arranged on one side, which is close to the inner side, of the second sandwich crosspiece 23, and in the installation process, the second tenon 32 can be avoided, so that the installation of the movable bar 3 is facilitated.

The first sandwich crosspiece 13 top is equipped with first spacing nail 4, and second sandwich crosspiece 23 top is equipped with second spacing nail 5, and first spacing nail 4 and second spacing nail 5 are used for restricting the left and right movement of movable bar 3. In addition, the second tenon 32 may be further provided with a limiting portion 33 for limiting the depth of the second limiting groove 21, and both the limiting portion 33 and the second limiting nail 5 may be used for limiting the position of the second tenon 32, and in this embodiment, the limiting portion 33 is disposed at a position where the first tenon 31 is connected to the main body of the movable bar 3, as shown in fig. 3, and the cross-sectional area of the main body portion of the movable bar 3 is larger than that of the second tenon 32. When the first tenon 31 is inserted into the bottom of the first limit groove 11, the second tenon 32 is inserted into the bottom of the second limit groove 21, the first side upright 1 is provided with the first limit pin 6, the second side upright 2 is provided with the second limit pin 8, and the first limit pin 6 and the second limit pin 8 are used for limiting the up-and-down movement of the movable bar 3.
