Description

Technical Field

[0001] This utility model relates to the field of pull rod technology, and more specifically to a luggage pull rod. Background Technology

[0002] The pull rod is installed on the bottom or back of the bag with screws or bolts. When the bag needs to be transported, press the pull rod to extend it onto the bag. By holding the pull rod, the bag can be tilted and moved, which saves effort and reduces friction with the bottom. Users can ensure that the bag can be moved smoothly with a small amount of pulling force.

[0003] To ensure smooth and easy sliding of the pull rod, there is a certain gap between each section. The pull rod includes a handle, a sleeve, and a sliding rod. The sliding rod slides on the sleeve to adjust the height of the handle. However, during use, the pull rod is a support component used to support the weight of the suitcase and withstand vibrations and impacts during movement. When the load or impact is too great, the gap between the sleeve and the sliding rod will increase, resulting in significant shaking during use and affecting normal operation. If the pull rod is damaged, it would be a waste to scrap the suitcase. However, removing and replacing the pull rod requires certain tools and involves disassembling it from the inside of the suitcase, which is a cumbersome process and can easily damage the suitcase's shell.

[0029] Sleeve 5, extension rod 3 is slidably provided inside sleeve 5, handle 4 is provided on extension rod 3, handle 4 controls extension rod 3 to slide inside sleeve 5;

[0030] Clamping block 1 is located at one end of sleeve 5. A support base 11 is provided on clamping block 1. A pressing block 17 is slidably provided on support base 11. An inclined slide groove 171 is provided on pressing block 17. A locking strip 16 that engages with sleeve 5 is provided on inclined slide groove 171. A spring 13 that pushes the pressing block 17 is provided on support base 11.

[0031] Reinforcing block 2 is located at the other end of sleeve 5, and reinforcing block 2 has a stabilizing block 26 that engages with the outer wall of sleeve 5. One end of sleeve 5 refers to the first connecting end 51, and the other end refers to the second connecting end 53 (e.g., Figure 1 (As shown).

[0032] Specifically, the sleeve 5 is the fixing part of the pull rod, and the extension rod 3 is the sliding part of the pull rod. During installation, the clamping block 1 and the reinforcing block 2 are fixed to the outer wall of the bag as supporting fixing parts. Then, the sleeve 5 is inserted through the reinforcing block 2 and inserted into the guide groove 111. As the sleeve 5 gradually slides in, the locking strip 16 is inserted into the groove 52 to fix the sleeve 5. Then, the screw 22 is rotated to make the stabilizing block 26 fit against the outer wall of the sleeve 5, thus fixing the sleeve 5 a second time and improving the stability of the pull rod during use. When the pull rod shakes or is damaged, the pressing block 17 can be squeezed and slid down along the guide post 14. At this time, the locking strip 16 will gradually move away from the groove 52 on the sleeve 5 under the guidance of the inclined slide groove 171, and then the stabilizing block 26 will move away from the sleeve 5, thus quickly removing the pull rod part. This improves the efficiency of pull rod replacement without the need for other external tools.

[0033] Preferably, a protective cover 12 is provided on the support base 11, and a guide block 162 that cooperates with the retaining strip 16 is provided on the protective cover 12. One end of the retaining strip 16 has a triangular portion 163 that engages with the sleeve 5, and the other end has a sliding portion 161. A guide rod 15 is provided on the sliding portion 161, and the guide rod 15 slides within the inclined groove 171.

The retaining strip 16 is located within the protective cover 162. 2. The guide block 162 restricts the sliding direction of the locking strip 16, so that it can only slide towards the groove 52 of the first connecting end 51. The sliding part 161 of the locking strip 16 is U-shaped. The width of the pressing block 17 is smaller than the groove width of the sliding part 161. When the locking strip 16 slides, the locking strip 16 will slide away from the sleeve 5 under the action of the pressing block 17 until it is disengaged from the sleeve 5. At this time, the sleeve 5 can be removed and replaced on the support base 11. Compared with the bolt fixing method, this method improves the removal and replacement effect of the pull rod.
