AI Technical Summary
Existing telescopic pole mechanisms are too long after being shortened, occupy a lot of space, and the wires are prone to motion interference or crushing damage.
The design employs a first and second locking assembly in conjunction with a pusher and a transfer member. The transfer member transmits thrust after shortening to unlock the locking assembly, enabling relative movement of the tube. Combined with the elastic layered arrangement of the wires, it avoids interference and compression by avoiding the wires.
This technology improves space utilization after the telescopic rod mechanism is shortened, avoids damage to the wires, and allows for flexible length adjustment.

Abstract
Claims
1. A telescopic rod mechanism, characterized in that: It includes a tubular structure, which includes a first tube body, a second tube body, and a third tube body, wherein the second tube body is sleeved on the first tube body, and the third tube body is sleeved on the second tube body; The telescopic rod mechanism also includes: A first locking assembly is disposed on the first tube body; the first locking assembly is configured to lock the second tube body and unlock the second tube body when pressure is applied, so as to move with the first tube body within the second tube body; A second locking assembly is disposed in the second tube body; the second locking assembly is configured to lock the third tube body and unlock the third tube body when compressed, so as to move with the second tube body within the third tube body; A pusher is disposed within the first tube and configured to push against the first locking assembly; A transfer member is telescopically connected between the first locking assembly and the second locking assembly; the transfer member is configured to transfer the pushing force of the pusher on the first locking assembly to the second locking assembly after being shortened; the transfer member has a cavity; A wire passes through the tubular structure and is at least partially disposed within the cavity. The wire is at least partially bent continuously in three-dimensional space to form an elastically deformable stacked arrangement structure, which can be elastically straightened or elastically bent.
2. The retractable lever mechanism of claim 1, wherein: The transmission component includes at least two sleeves that are fitted one on top of the other, and the at least two sleeves are movable relative to each other. The first locking assembly and the second locking assembly are each connected to the corresponding sleeve. After the transmission member is shortened, each of the sleeves abuts against the first locking assembly and the second locking assembly respectively, so as to transmit the thrust to the second locking assembly.
3. The retractable lever mechanism of claim 2, wherein: The transmission component includes two cylindrical sleeves, with the longer sleeve fixed to the second locking assembly and the shorter sleeve fixed to the first locking assembly.
4. A telescopic pole arrangement according to any one of claims 1 to 3, wherein: The conductor includes two stacked arrangement structures, which are spaced apart and respectively constructed on opposite sides of the second latching assembly.
5. The retractable rod mechanism of claim 4, wherein: The layered arrangement structure is spiral.
6. The retractable lever mechanism of claim 1, wherein: The second tube body is provided with two first positioning parts at intervals; the third tube body is provided with two second positioning parts at intervals. Both the first locking assembly and the second locking assembly include a fixed part, an elastic part, and a movable part. The fixed part is fixed to the first tube or the second tube, and the elastic part is disposed between the fixed part and the movable part. The movable part can move horizontally relative to the fixed part to cause the elastic part to elastically deform, and the elastic part can rebound to connect the movable part to the corresponding first positioning part or the second positioning part.
7. A telescopic linkage as claimed in claim 6 wherein: The moving part has an inclined surface; The pusher or the transfer member has a mating surface, which is configured to push against the inclined surface, causing the moving part to move horizontally.
8. The retractable lever mechanism of claim 1, wherein: The length of the first tube is less than the length of the second tube, and the length of the second tube is less than the length of the third tube.
9. A tie rod characterized in that, include: The telescopic rod mechanism as described in any one of claims 1 to 8; The grip is connected to the telescopic rod mechanism and is configured to drive the telescopic rod mechanism to extend or retract.
10. A luggage case characterized by, include: The pull rod as described in claim 9; The housing is connected to the pull rod; A driven wheel is rotatably provided in the box body.
