Summary of the invention
To overcome above-mentioned the deficiencies in the prior art, the purpose of the present invention is to provide a kind of multi-functional case drawbars, not only
Convenient for users to pushing and pulling luggage, and it can disassemble and be used as walking stick with free extension, vdiverse in function, user
Just.
To achieve the goals above, the technical solution adopted by the present invention is that:
A kind of multi-functional case drawbar, including tubular sleeve 3 open at one end, 3 opening of sleeve is tapped with convex thread 8,
3 opening of sleeve is furnished with the end cap 4 being mutually threadedly engaged, and running through at 4 center of end cap has a telescopic rod 2, and telescopic rod 2 is located at set
3 inside one end of cylinder are equipped with piston 5, and piston 5 and sleeve 3 are mutually interference fitted, and telescopic rod 2 is located at 3 outside one end of sleeve and vertically sets
There is the handle 1 of direct rod shape, 3 external vertical of sleeve is equipped with the installation sheet 7 of several tabular apertures, and 3 closed end of sleeve is provided with one
Venthole 9.
5 end of piston is equipped with wear-resistant pad 6.
The sleeve 3 and installation sheet 7 are manufactured from aluminum alloy, and sleeve 3 and installation sheet 7 pass through welded connecting.
The telescopic rod 2 and handle 1 are manufactured from aluminum alloy, and telescopic rod 2 and handle 1 pass through welded connecting.
The piston 5 is manufactured in a tubular form by rubber material, and 5 sets of piston are fixed on telescopic rod 2 and through screw.
The wear-resistant pad 6 is manufactured from aluminum alloy, and wear-resistant pad 6 is connect by welding with telescopic rod 2.
The end cap 4 is manufactured from aluminum alloy, the relief hole on end cap 4 and 2 clearance fit of telescopic rod.
Beneficial effects of the present invention:
The multi-functional case drawbar can pass through the back side that sleeve is fixed on luggage by installation sheet by screw during installation
Suitable position.Handle can be held when use and pulls telescopic rod, allow piston to move in sleeve, so that freely telescopic rod exist
It extracts or is inserted into sleeve.Since piston and sleeve are interference fitted, the position of moving telescopic bar that can be stable.And user
End cap can also be screwed off from sleeve, telescopic rod is extracted out of sleeve, and telescopic rod and handle are made as walking stick or shoulder pole
With.
The multi-functional case drawbar convenient for users to pushing and pulling luggage, and can not only be disassembled with free extension
It is used as walking stick, it is vdiverse in function, it is easy to use.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the multi-functional case drawbar of the present invention.
Fig. 2 is the structure broken away view of the multi-functional case drawbar of the present invention.
Wherein, 1-handle, 2-telescopic rods, 3-sleeves, 4-end caps, 5-pistons, 6-wear-resistant pads, 7-installation sheets,
8-convex threads, 9-ventholes.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
The multi-functional case drawbar includes tubular sleeve 3 open at one end combined with Figure 1 and Figure 2, and 3 opening of sleeve is attacked
There is convex thread 8,3 opening of sleeve is furnished with the end cap 4 being mutually threadedly engaged, and running through at 4 center of end cap has a telescopic rod 2, stretches
Contracting bar 2 is located at 3 inside one end of sleeve and is mutually interference fitted equipped with piston 5, piston 5 and sleeve 3, and 5 end of piston is equipped with wear-resistant pad
6, telescopic rod 2 is located at the handle 1 that 3 outside one end of sleeve is vertically equipped with direct rod shape, and 3 external vertical of sleeve is equipped with several tabulars and opens
The installation sheet 7 in hole, 3 closed end of sleeve are provided with a venthole 9.When venthole 9 can allow piston 5 movable in sleeve 3, air
It can be freely accessible to sleeve 3 or the air in sleeve 3 is discharged.
Sleeve 3 and installation sheet 7 are manufactured from aluminum alloy, sturdy and durable, and corrosion resistance is good, sleeve 3 and installation sheet 7
Pass through welded connecting.Telescopic rod 2 and handle 1 are manufactured from aluminum alloy, sturdy and durable, and corrosion resistance is good, telescopic rod 2
Pass through welded connecting with handle 1.Piston 5 is manufactured in a tubular form by rubber material, and elasticity is good, and coefficient of friction is big, and stability is good, living
5 sets of plug is fixed on telescopic rod 2 and through screw.Wear-resistant pad 6 is manufactured from aluminum alloy, sturdy and durable, and corrosion resistance is good
Good, wear-resistant pad 6 is connect by welding with telescopic rod 2.End cap 4 is manufactured from aluminum alloy, sturdy and durable, and corrosion resistance is good,
Relief hole and 2 clearance fit of telescopic rod on end cap 4, piston 5 can not pass through the relief hole of end cap 4.
The working principle of the invention:
The multi-functional case drawbar can pass through the back that sleeve 3 is fixed on luggage by installation sheet 7 by screw during installation
Face suitable position.Handle 1 can be held when use and pulls telescopic rod 2, allow piston 5 to move in sleeve 3, to will freely stretch
