Description

Technical Field

[0001] The utility model relates to the technical field of luggage drawbars, in particular to an aluminum alloy drawbar structure. Background Art

[0002] Luggage trolleys (also called luggage trolleys or zipper rods) are an important part of travel luggage, mainly used to improve the convenience of carrying and save effort for travelers when moving luggage. Trolleys are usually made of materials such as metal, plastic or aluminum alloy, which can withstand large pulling forces and help luggage to move smoothly in different environments.

[0003] Currently, existing luggage trolleys on the market only have a simple height adjustment function. People usually place additional items on top of the luggage, such as handbags, but since there is no cross bar structure in the middle of the trolley, the placed items are easy to fall from the gap in the middle of the trolley.

Detailed implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] As Figures 1-5 shown, a technical solution provided by the present invention:

[0025] An aluminum alloy pull rod structure includes a grip 1. Movable sleeves 2 are fixedly connected to both sides of the bottom end of the grip 1. A fixed sleeve 3 is movably connected below the movable sleeve 2. A pulling mechanism is arranged between the inside of the grip 1, the movable sleeve 2 and the fixed sleeve 3. The pulling mechanism includes a button 5. The button 5 is movably installed below the middle of the grip 1. Both ends of the button 5 are movably connected to the grip 1 through a first spring 6. A support rod 7 is arranged at the top end of the button 5. The pulling mechanism further includes a first fixed rod 8. The first fixed rod 8 is arranged at the upper sides of the grip 1 close to the support rod 7. A second fixed rod 9 is arranged outside the first fixed rod 8. A pulling rope 10 is movably arranged between the upper end of the support rod 7, the lower end of the first fixed rod 8 and the upper end of the second fixed rod 9. The pulling mechanism further includes a second spring 11. The second spring 11 is arranged inside the lower sides of both sides of the movable sleeve 2. A plurality of positioning holes 12 are sequentially arranged from top to bottom on the outer walls of both sides of the fixed sleeve 3. A positioning block 13 is arranged at one end of the second spring 11 close to the positioning hole 12. A third fixed rod 14 and a fourth fixed rod 15 are sequentially arranged in a staggered manner at the upper part of the movable sleeve 2 close to the second spring 11. Fixed rods 16 are arranged at the upper and lower ends of the side of the fixed sleeve 3 away from the positioning block 13. The other end of the pulling rope 10 sequentially passes below the third fixed rod 14, above the fourth fixed rod 15 and through the middle parts of the two fixed rods 16 to connect the positioning block 13;

[0026] In this embodiment, when it is necessary to stretch the movable sleeve 2 and the fixed sleeve 3, hold the grip 1 and press the button 5. The button 5 controls the strut 7 to lift and support the pull rope 10. After the pull rope 10 is lifted, it stretches the positioning block 13, pulls the end of the positioning block 13 out of the inside of the positioning hole 12, and then lift the movable sleeve 2. The movable sleeve 2 rises along the fixed sleeve 3 until it stops after being stretched to an appropriate position, and then release the button 5. At this time, the first spring 6 controls the button 5 to reset, and the second spring 11 controls the positioning block 13 to reset and insert into the positioning hole 12 at the current position, making it more convenient to adjust the length.

[0027] As Figure 2 and Figure 5 shown, receiving grooves 4 are provided on the inner walls of both the movable sleeve 2 and the fixed sleeve 3, and crossbar mechanisms are provided inside the receiving grooves 4. The crossbar mechanism includes a support frame 17. The support frame 17 is movably installed inside the receiving groove 4. Nuts sleeves 18 and threaded heads 19 are respectively provided at the ends of the two support frames 17. The nuts sleeve 18 is internally threaded with the end of the support frame 17.

[0028] In this embodiment, when it is necessary to set a crossbar structure between the movable sleeve 2 or the fixed sleeve 3, pull the support frame 17 in the receiving groove 4 at the corresponding position outward until the two support frames 17 are horizontally angled, and then twist the nuts sleeve 18. The nuts sleeve 18 rotates and extends along the end of the left support frame 17 and is threadedly connected to the threaded head 19 on the right, so that a crossbar structure can be set at this position to facilitate placing other items.

[0029] Working principle: When it is necessary to stretch the movable sleeve 2 and the fixed sleeve 3, hold the grip 1 and press the button 5. The button 5 controls the strut 7 to lift and support the pull rope 10. After the pull rope 10 is lifted, it stretches the positioning block 13, pulls the end of the positioning block 13 out of the inside of the positioning hole 12, and then lift the movable sleeve 2. The movable sleeve 2 rises along the fixed sleeve 3 until it stops after being stretched to an appropriate position, and then release the button 5. At this time, the first spring 6 controls the button 5 to reset, and the second spring 11 controls the positioning block 13 to reset and insert into the positioning hole 12 at the current position; when it is necessary to set a crossbar structure between the movable sleeve 2 or the fixed sleeve 3, pull the support frame 17 in the receiving groove 4 at the corresponding position outward until the two support frames 17 are horizontally angled, and then twist the nuts sleeve 18. The nuts sleeve 18 rotates and extends along the end of the left support frame 17 and is threadedly connected to the threaded head 19 on the right.

[0030] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present utility model, and are not used to limit the present utility model.
