[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0019] like Figure 1-6As shown, a wall-mounted pull rod for a suitcase includes two arc-shaped fixed cavities 1. A through groove 2 is formed on the inner side of each fixed cavity 1. At least two sets of limiting parts are formed on the side of the through groove 2, and limiting parts are provided at both ends of the through groove 2. Each set of limiting parts includes limiting grooves 3 arranged on both sides of the through groove 2 and communicating with the through groove 2. A movable cavity 4 is slidably connected inside the fixed cavity 1. The upper end of the movable cavity 4 is open, and an adjustment groove 5 is formed on the side of the movable cavity 4. A fixed block 6 is provided inside the movable cavity 4. Two inclined elastic rods 7 are symmetrically arranged on the fixed block 6. A positioning rod 8 is provided at the upper end of the elastic rod 7. The positioning rod 8 extends out of the movable cavity 4 through the adjustment groove 5. A limiting frame 9 is also included, with both elastic rods 7 located inside the limiting frame 9. A fixing rod 10 is provided on the fixed block 6 and slidably connected to the limiting frame 9. The upper end of the fixing rod 10... The system includes a stop block 11, a spring 12 fitted on a fixed rod 10, the spring 12 being located between the limiting frame 9 and the stop block 11, a crossbar 13, a hollow crossbar 13, two movable cavities 4 fixed at both ends of the crossbar 13 and communicating with the interior of the crossbar 13, an installation groove on the lower surface of the crossbar 13, a pressure block 14 inside the installation groove, a retaining ring 15 on the upper surface of the pressure block 14, a groove on the pressure block 14, a second spring 16 located inside the groove and abutting against the inner top wall of the crossbar 13, and guide mechanisms located inside the crossbar 13 and on both sides of the retaining ring 15, the guide mechanisms including two pulleys 17 and a pull rope 18, one end of the pull rope 18 being fixedly connected to the limiting frame 9, and the other end of the pull rope 18 passing over the two pulleys 17 and being fixedly connected to the retaining ring 15.

[0020] Both fixed cavities 1 are installed at the two corners inside the suitcase, giving both fixed cavity 1 and movable cavity 4 a certain curvature, which can improve the bending resistance of fixed cavity 1 and movable cavity 4. Furthermore, the thickness of fixed cavity 1 is only 1 / 2 to 1 / 3 of the thickness of a single pull rod of the existing suitcase, which can make fixed cavity 1 fit more closely to the inner wall of the suitcase and reduce the protruding thickness.

[0021] When the movable cavity 4 is housed in the fixed cavity 1, both positioning rods 8 are located in the limiting grooves 3 on both sides of the bottom of the through groove 2 on the fixed cavity 1. Since the positioning rods 8 abut against the limiting grooves 3, the movable cavity 4 cannot move freely, thus effectively housing the movable cavity 4 in the fixed cavity 1.

[0022] When it is necessary to pull the movable cavity 4 out of the fixed cavity 1, the pressure block 14 needs to be pressed down towards the crossbar 13 first, so that the pressure block 14 enters the interior of the crossbar 13. When the pressure block 14 moves upward inside the crossbar 13, it will drive one end of the pull rope 18 to move upward through the retaining ring 15. One of the pulleys 17 is located on one side of the retaining ring 15. Therefore, when one end of the pull rope 18 moves upward, the other end of the pull rope 18 will also respond quickly and move upward with the cooperation of the two pulleys 17. When the pull rope 18 moves upward, it will pull the limiting frame 9 to move upward. When the limiting frame 9 moves upward, under the compression of the limiting frame 9, the inclined elastic rod 7 will tilt towards the center of the limiting frame 9, so that the positioning rod 8 moves from the limiting groove 3 into the through groove 2. When the two positioning rods move upward, the limiting frame 9 will cause the inclined elastic rod 7 to tilt towards the center of the limiting frame 9, so that the positioning rod 8 moves from the limiting groove 3 into the through groove 2. When all rods 8 are located within the through groove 2, the movable cavity 4 can be pulled upward by the crossbar 13. When it moves upward more than 2cm, the pressure block 14 can be released. Under the action of spring 12 and spring 26, the pressure block 14 tends to return to its original state. At the same time, the limiting frame 9 also tends to move downward. Both positioning rods 8 are in contact with the inner wall of the through groove 2. As the movable cavity 4 moves upward, when it reaches a certain height, the positioning rod 8 will encounter the limiting groove 3 set at a higher position on the through groove 2. Under the action of the elastic rod 7, the positioning rod 8 will enter the limiting groove 3. At this time, the positioning rod 8 will be stuck in the limiting groove 3, and the movable cavity 4 cannot move upward or downward. At this time, the movable cavity 4 can stably extend out of the fixed cavity 1.

[0023] When it is necessary to retract the movable cavity 4, simply press down the pressure block 14 again to allow the two positioning rods 8 to re-enter the through groove 2. Then, by moving the movable cavity 4, the two positioning rods 8 can be moved into the two lower limiting grooves 3.

[0024] When the positioning rod 8 is located in the limiting groove 3, the positioning rod 8 can move within a small range and a small amplitude within the limiting groove 3, thereby ensuring that the positioning rod 8 can move from the through groove 2 to the limiting groove 3, and also ensuring that the positioning rod 8 can move from the limiting groove 3 to the through groove 2.

[0025] Furthermore, both the fixed cavity 1 and the movable cavity 4 are made of aluminum alloy.

[0026] Furthermore, the pull rope 18 is a steel wire rope.

[0027] Furthermore, the width at the entrance of the limiting groove 3 is greater than the diameter of the positioning rod 8, which facilitates the positioning rod 8 to enter the limiting groove 3 from the through groove 2.

[0028] Furthermore, both the limiting frame 9 and the elastic rod 7 are made of metal to improve wear resistance.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
