[0008] By adopting the above technical scheme, the pull rod is used to pull out the two inner tubes from the two outer tubes, and the locking mechanism needs to be removed to limit the sliding of the inner tube. Therefore, the user needs to hold the rotating pipe and rotate it to rotate the two second connecting blocks. When the rotating pipe rotates, the two first tube bodies are limited by the two accommodating grooves, so the two first tube bodies and the two second tube bodies do not rotate together. When the two second connecting blocks rotate, they press the two first inclined planes to make the two first connecting blocks descend. When the two first connecting blocks descend, they pull the two control rods down, which removes the sliding restriction of the two locking mechanisms on the inner tube. At this time, the rotating pipe can be pulled out to pull out the two inner tubes from the two outer tubes, thereby facilitating the dragging of the luggage. The unlocking method of holding and rotating the rotating pipe can better exert force when the locking mechanism is unlocked, so it can more easily unlock the locking mechanism.

[0020] By adopting the technical scheme, the limiting plate plays a limiting prompting role on the insertion depth of the rotating pipe when the rotating pipe is inserted into the second pipe body.

[0021] Preferably, second limiting ring grooves are formed in the outer walls of the two end portions of the rotating pipe, mounting ring grooves are formed in the end faces of the two ends of the two second pipe bodies away from each other, the two limiting plates are respectively arranged in the two mounting ring grooves, a plurality of arc-shaped pressing plates are circumferentially arranged in the two mounting ring grooves, one end of each of the plurality of pressing plates is connected with the bottom wall of the corresponding mounting ring groove, and the other end of each of the plurality of pressing plates extends into the adjacent second limiting ring groove and abuts against the side wall of the adjacent second limiting ring groove, so that the end portion of the rotating pipe is pressed against the limiting plate.

The two bolts for fixing the two inner tubes 13 to the two first tube bodies 21 are threadedly connected to the bottom end of each of the two cylindrical members.

[0042] With reference to Figures 1-5 , the middle part of the mounting block 141 is provided with a first matching inclined surface 61, and the distance from the first matching inclined surface 61 to the first limiting hole 142 gradually decreases from the top end of the first matching inclined surface 61 to the bottom end of the first matching inclined surface 61. A control rod 23 is slidably connected to each of the two cylindrical members 22 along the length direction of the outer tube 12, and the bottom end of each of the two control rods 23 extends into the inner cavity of each of the two inner tubes 13 through the two cylindrical members 22. A second matching inclined surface 62 is arranged on the bottom end of each of the two control rods 23, and the two second matching inclined surfaces 62 respectively abut the two first matching inclined surfaces 61. A first connecting block 24 is arranged on the top end of each of the two control rods 23, and a first inclined surface 25 with an inclination angle opposite to that of the same side second matching inclined surface 62 is arranged on the top end of each of the two first connecting blocks 24.

[0043] With reference to Figure 1 , Figure 2 and Figure 4 , the top end of each of the two first tube bodies 21 extends out of the corresponding accommodating groove 111 and is connected to a second tube body 26. The inner cavities of the two second tube bodies 26 respectively communicate with the inner cavities of the two first tube bodies 21. A rotating tube 3 is arranged between the two second tube bodies 26, and the two ends of the rotating tube 3 are respectively inserted into and rotatably connected to the two second tube bodies 26. The rotating axis of the rotating tube 3 coincides with its own axis.

[0044] Referring to Figure 1 , Figure 2 , Figure 4 , the second connecting blocks 31 are fixed on both ends of the rotating pipe 3 by bolts, the two second connecting blocks 31 are located in the two first pipe bodies 21 respectively, the second inclined surfaces 36 are arranged on the bottom ends of the two second connecting blocks 31 respectively, the two second inclined surfaces 36 are fitted with the two first inclined surfaces 25 respectively, and the two second connecting blocks 31 are used to drive the two first connecting blocks 24 to move downward when the rotating pipe 3 rotates.

[0045] Referring to Figure 1 , Figure 2 and Figure 4 , the first springs 27 are arranged in the two cylindrical members 22 and used to press the first connecting blocks 24 on the second connecting blocks 31, the two first springs 27 are sleeved on the two control rods 23 respectively, one ends of the two first springs 27 are in abutment with the inner walls of the two cylindrical members 22 respectively, and the other ends of the two first springs 27 are in abutment with the bottom ends of the two second connecting blocks 31 respectively. The two first springs 27 press the two first connecting blocks 24 on the two second connecting blocks 31 respectively when no external force acts.

[0046] Referring to Figure 1 , Figures 6-8 , the sleeve pipe 4 is further sleeved on the rotating pipe 3. The sleeve pipe 4 comprises two arc-shaped fixing plates 42 and a handle pipe 43, the sliding grooves 32 are arranged on the outer wall of the rotating pipe 3, the sliding blocks 41 are fixedly connected on the two arc-shaped fixing plates 42 respectively, the two sliding blocks 41 are slidably connected in the two sliding grooves 32 along the length direction of the rotating pipe 3 respectively, and the two arc-shaped fixing plates 42 are fitted on the surface of the rotating pipe 3. The first limiting ring grooves 51 are arranged on the side end faces of the two second pipe bodies 26 which are close to each other respectively, the arc-shaped insertion blocks 52 are arranged on the two ends of the two arc-shaped fixing plates 42 respectively, and the four arc-shaped insertion blocks 52 are inserted and rotatably connected in the adjacent first limiting ring grooves 51.

[0047] Referring to Figure 1 , Figures 6-8 , the handle pipe 43 is sleeved on the two arc-shaped fixing plates 42, the two sliding grooves 44 are formed between the two arc-shaped fixing plates 42, and the sliding blocks 45 are arranged on the inner wall of the handle pipe 43.

[0048] Referring to Figure 1 , Figures 6-8 , the end faces of the two arc-shaped fixing plates 42 and the end faces of the handle pipe 43 are fitted with the end faces of the two second pipe bodies 26, and the diameter of the handle pipe 43 is equal to the diameter of the two second pipe bodies 26. In this way, the end portions of the two second pipe bodies 26 will not scratch the hands of the user when the user grips the handle pipe 43, and the overall appearance of the pull rod is also improved.

[0049] Referring to Figure 1 , Figures 6-9 , the two second pipe bodies 26 are provided with mounting ring grooves 54 on the end faces away from each other, and the two mounting ring grooves 54 are fixed with limiting plates 53, and the two end faces of the rotating pipe 3 abut against the two limiting plates 53. The outer walls of the two side end portions of the rotating pipe 3 are provided with second limiting ring grooves 34, and the two mounting ring grooves 54 are circumferentially provided with a plurality of arc-shaped pressing plates 55, one end of the plurality of pressing plates 55 is connected with the bottom wall of the corresponding mounting ring groove 54, and the other end of the plurality of pressing plates 55 extends into the adjacent second limiting ring groove 34 and abuts against the side wall of the adjacent second limiting ring groove 34, so as to press the end portion of the rotating pipe 3 against the limiting plate 53.

[0050] Referring to Figure 1 , Figures 6-9 , the distance from the plurality of pressing plates 55 to the adjacent limiting plate 53 gradually increases from the end where the plurality of pressing plates 55 abut against the side wall of the adjacent second limiting ring groove 34 to the end where the plurality of pressing plates 55 are connected with the bottom wall of the corresponding mounting ring groove 54. Meanwhile, the two end faces of the rotating pipe 3 are provided with guide inclined surfaces 35. The inclined arrangement of the plurality of pressing plates and the provision of the guide inclined surfaces 35 on the rotating pipe 3 can make the end of the plurality of pressing plates not connected with the second pipe body 26 more easily enter the mounting ring groove 54 when the rotating pipe 3 is inserted into the second pipe body 26, thereby reducing the assembly difficulty of the second pipe body 26 and the rotating pipe 3.

[0051] Referring to Figures 1-9 , the specific unlocking operation of the pull rod is as follows:

[0052] When it is needed to release the locking of the inner pipe 13 by the lock catch mechanism 14, the user holds the handle, and then rotates the handle tube 43, which will rotate the two arc-shaped fixed plates 42, and the two arc-shaped fixed plates 42 will rotate the rotating pipe 3. The rotating pipe 3 will rotate the two second connecting blocks 31, and the two second connecting blocks 31 will press the two first inclined surfaces 25 to make the two first connecting blocks 24 move downward, and the two first connecting blocks 24 will move the two control rods 23 downward and compress the two first springs 27 under stress, and the two control rods 23 will move the two mounting blocks 141 away from the adjacent first limiting grooves through the cooperation of the first and second cooperation inclined surfaces 61 and 62, so that the two insertion rods 144 are separated from the two second limiting holes 143, and at this time, the two inner pipes 13 can be pulled out of the two outer pipes 12 by pulling the rotating pipe 3, thereby facilitating the dragging of the luggage. When the rotating pipe 3 rotates, the two first pipe bodies 21 and the two second pipe bodies 26 will not rotate with the rotating pipe 3 because of the limitation of the two accommodating grooves 111 to the two first pipe bodies 21.

[0053] After the inner tube 13 is pulled up, the user of the pull rod releases the rotation of the handle 43, and the two first springs 27 rebound to push the two first connecting blocks 24 and the two control rods 23 to move upward. When the two first connecting blocks 24 move upward, they push the two second connecting blocks 31 to rotate and reset. When the two connecting blocks rotate and reset, they take the rotating tube 3, the two arc-shaped fixed plates 42 and the handle 43 to rotate and reset.

[0054] The unlocking mode of gripping and rotating the rotating tube 3 can better apply force relative to pressing the button when the locking mechanism 14 releases the locking of the inner tube 13, and thus can more easily release the locking of the inner tube 13 by the locking mechanism 14.

[0055] Of course, the above is only a typical example of the present application, and in addition, the present application can have other various specific embodiments, and any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of the present application.
