[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] like Figure 1-2 As shown, a drying rod assembly with synchronous extension and retraction at both ends includes a support tube 1, a first slide bar 2 and a second slide bar 3. The support tube 1, the first slide bar 2 and the second slide bar 3 are all horizontally arranged, the first slide bar 2 and the second slide bar 3 are symmetrically arranged at the two ends of the support tube 1 and matched with the support tube 1, the inner ends of the first slide bar 2 and the second slide bar 3 are respectively inserted into the support tube 1 from the two ends of the support tube 1 and slidably arranged, and the first slide bar 2 and the second slide bar 3 are driven by a synchronous moving structure to perform synchronous extension and retraction movements.

[0022] The first slide bar 2 and the second slide bar 3 are connected by a synchronous moving structure. When telescoping, only one of the first slide bar 2 and the second slide bar 3 needs to be extended or retracted, and the other one will also be extended or retracted synchronously, thereby improving the convenience of use.

[0023] like Figure 3 to Figure 5 As shown, the preferred technical solution, the synchronous moving structure includes a first pull rope 5, a second pull rope 7, a first roller 4 and a second roller 6, the first roller 4 and the second roller 6 are symmetrically arranged at both ends of the support tube 1 and are respectively located at the same end of the first slide bar 2 and the second slide bar 3, the first roller 4 and the first slide bar 2 are located at the same end of the support tube 1, the second roller 6 and the second slide bar 3 are located at the other end of the support tube 1, one end of the first pull rope 5 is connected to the inner end of the first slide bar 2, the other end of the first pull rope 5 extends toward the outward direction, then passes around the first roller 4 and then extends toward the inward direction and is connected to the inner end of the second slide bar 3, one end of the second pull rope 7 is connected to the inner end of the second slide bar 3, the other end of the second pull rope 7 extends toward the outward direction, then passes around the second roller 6 and then extends toward the inward direction and is connected to the inner end of the first slide bar 2.

[0024] The directions of the two ends of the first pull rope 5 and the second pull rope 7 are changed respectively by the first roller 4 and the second roller 6, so that the two ends of the first pull rope 5 and the second pull rope 7 move in opposite directions. Therefore, when extending, the first slide bar 2 is pulled outward, and the end of the second pull rope 7 connected to the first slide bar 2 moves outward. Due to the setting of the second roller 6, the end of the second pull rope 7 connected to the second slide bar 3 moves from the other end toward the outside, so that the second slide bar 3 is pulled outward, so that the first slide bar 2 and the second slide bar 3 are extended synchronously;

[0025] Similarly, when retracting, the first slide bar 2 is moved inward, and due to the connection of the first pull rope 5 and the setting of the first roller 4, the second slide bar 3 will be driven to retract synchronously;

[0026] Conversely, only extending or retracting the second slide bar 3 can also drive the first slide bar 2 to extend or retract synchronously.

[0027] like Figure 6 As shown, in a preferred technical solution, the inner wall of the support tube 1 is recessed toward the outside to form a groove 8 extending along the length of the support tube 1 , and the first pull rope 5 , the second pull rope 7 , the first roller 4 and the second roller 6 are all arranged in the groove 8 .

[0028] Through this solution, a groove 8 is formed to facilitate the installation of the first pull rope 5, the second pull rope 7, the first roller 4 and the second roller 6.

[0029] According to a preferred technical solution, the surfaces of the first slide bar 2 and the second slide bar 3 are provided with limiting convex marks arranged along the length direction of the support tube 1, and the inner wall of the support tube 1 is provided with limiting grooves adapted to the limiting convex marks.

[0030] By embedding the limiting convex mark into the limiting groove for sliding, the first sliding rod 2 and the second sliding rod 3 can be prevented from rotating in the support tube 1 .

[0031] like Figure 7 As shown, a preferred technical solution is provided, wherein four supporting protrusions 9 are protruded on the inner wall of the support tube 1, two of the four supporting protrusions 9 are located above the first slide bar 2 and the second slide bar 3, and the remaining two are located below the first slide bar 2 and the second slide bar 3, the outer walls of the first slide bar 2 and the second slide bar 3 slide against the four supporting protrusions 9 and form a gap between the interior of the support tube 1 and the first slide bar 2 and the second slide bar 3, and the first pull rope 5, the second pull rope 7, the first roller 4 and the second roller 6 are all arranged in the gap.

[0032] A gap is formed by the support of the supporting protrusion 9, which facilitates the installation of the first pull rope 5, the second pull rope 7, the first roller 4 and the second roller 6.
