Especially in recent years, affected by the epidemic, many people have been exercising indoors for safety reasons. Door-mounted horizontal bars with simple structure, small footprint and convenient use are used by many people. Common door-mounted horizontal bars mostly include a gripping rod and telescopic rods arranged on both sides of the gripping rod. A screw is fixedly provided in the gripping rod, and a first screw portion and a second screw portion are provided on the screw portion, which respectively cooperate with the two telescopic rods. The first screw portion and the second screw portion have a rotating The threads are in opposite directions. When installing this horizontal bar on the door, it is necessary to first control the rotation of the telescopic rods on both sides so that the telescopic rods extend toward the two sides of the gripping rod until the two ends of the horizontal bar on the door are respectively against the wall. Only when the two ends of the horizontal bar on the door are against the wall can the telescopic rod be prevented from rotating relative to the wall, and the user can control the rotation of the gripping rod and make the two ends of the horizontal bar on the door respectively press against the wall.

[0031] To facilitate understanding by those skilled in the art, the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 8 As shown, a bidirectional structure horizontal bar body includes a gripping rod 1 and a telescopic rod that is telescopically arranged in the gripping rod 1, wherein the telescopic rod includes a first telescopic rod 2 and a second telescopic rod 3 that extend to both sides of the gripping rod 1 respectively, a first screw portion 21 is provided on the first telescopic rod 2, and a second screw portion 31 is provided on the second telescopic rod 3. The gripping rod 1 is provided with a first threaded portion 16 and a second threaded portion 18 that respectively cooperate with the first screw portion 21 and the second screw portion 31, the first threaded portion 16 and the second threaded portion 18 rotate in opposite directions, and a positioning portion 22 is provided on the first screw portion 21, and a positioning groove 32 that cooperates with the positioning portion 22 is provided on the second screw portion 31. The portion 22 can slide relatively in the positioning groove 32, and the positioning portion 22 cooperates with the positioning groove 32 to make the first telescopic rod 2 and the second telescopic rod 3 rotate synchronously. In this structure, the positioning portion 22 and the positioning groove 32 make the first telescopic rod 2 and the second telescopic rod 3 rotate synchronously. The user only needs to control the rotation of a certain telescopic rod to simultaneously control the extension and retraction of the first telescopic rod 2 and the second telescopic rod 3, which is convenient for the user to quickly install the horizontal bar on the door. In this structure, the first telescopic rod 2 and the second telescopic rod 3 are extended and retracted synchronously, so that the length of the extension or shortening of the telescopic rod and the second telescopic rod 3 is the same, which is beneficial to avoid a short service life of a certain telescopic rod due to a long extension length, thereby extending the service life of the horizontal bar on the door.

[0033] The positioning groove 32 of the present invention is provided with a pressing wall 34 on one side, and the positioning portion 22 is provided on the side of the first screw portion 21 and abuts against the pressing wall 34. This structure is conducive to reducing the length of the first telescopic rod 2 and increasing the contact area between the positioning portion 22 and the positioning groove 32, thereby avoiding damage to the positioning portion 22 and the positioning groove 32, and is conducive to extending the service life of the horizontal bar on the door. The positioning portion 22 and the pressing wall 34 in this embodiment can be a plane as shown in the accompanying drawings of the specification, or can be other shapes. It is only necessary for the positioning portion 22 and the pressing wall 34 to cooperate to make the first telescopic rod 2 and the second telescopic rod 3 rotate synchronously.

[0034] The positioning groove 32 is provided in the second screw portion 31, and the first telescopic rod 2 is passed through the positioning groove 32 and can be retracted into the positioning groove 32. Since the first telescopic rod 2 can be retracted into the second threaded portion 18, it is beneficial to avoid interference between the first telescopic rod 2 and the second telescopic rod 3, which is beneficial to increase the telescopic range of the horizontal bar on the door and facilitate the installation of the horizontal bar on the door.

[0035] Since the positioning groove 32 is provided in the second screw portion 31, the strength of the second screw portion 31 will be reduced.
