The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the present invention is done concrete introduction.

Referring to Fig. 1 to Fig. 5; Case drawbar of the present invention comprises: pipe 2, shell 3, handle shell 5 in handlebar stem 1, a pair of the stretching; Wherein, handlebar stem 1 is preferably the U type, a pair of flexible in pipe 2 be arranged at two ends of handlebar stem 1; Shell 3 is socketed in flexible interior pipe 2 outsides, and on shell 3, also is formed with lock hole 4; Handle shell 5 is coated with the comfortableness of operating with raising in the outside of handlebar stem 1, and on handle shell 5, is provided with button assembly.

Specifically, button assembly comprises outer by press button 6, interior press button 7 and the connecting rod stage clip 8 pressed.

As a kind of preferred, handle shell 5 is assembled by two and half housings, is formed with on one of them half housing to be used to insert the installation head 9 of flexible interior pipe 2 ends to achieve a fixed connection.Further, in order to increase the fastness of connection, can also adopt screw with installation head 9 and flexible interior pipe 2 lockings, be provided with installing hole so manage 2 in flexible, this is easy to expect, does not give unnecessary details here.

Pipe 2 must be able to be accommodated in shell 3 inside in flexible, so pipe 2 is similar with the cross sectional shape of shell 3 in flexible, and its area of section is less than the area of section of shell 3.As a kind of concrete embodiment, flexible interior pipe 2 is circular or square with the cross sectional shape of shell 3.

To the inner telescopic tube 2 out from the tube and the lock housing 3, luggage trolley locking assembly further includes an inner tube, including: stretching the inner tube 2 is set inside the guide rod 10, driven by the guide rod 10 in order to realize the displacement slide block 11 and the guide block 12, the guide block 12 is provided with a locking hole 4 with a locking lever 13 and the lock lever 13 automatically reset spring 14, the guide block 12 and the slider 11 is mounted on the inner sleeve 15 as in endoscopy the outer sleeve 15 as the housing 16 with, the inner telescopic tube 2, the inner and the outer jacket 15, as jacket 16 as by means of a locking projection is provided with a C-ring 17 is fixedly connected.During use, flexible interior pipe 2 is pulled out from shell 3, and when arriving lock hole 4 positions, securing rod 13 resets under the effect of stage clip 14, thereby realizes cooperating with lock hole 4.Certainly, C type ring 17 is provided with locking projections, look in so cover, outward look cover 16 and flexible in latch recess must be arranged on the pipe 2, this is easy to expect, does not give unnecessary details here.

As a kind of concrete structure, the end of securing rod 13 is conical or hemispheric, so just helps making securing rod 13 to withdraw from lock hole 4 under external force, makes flexible interior pipe 2 be received into shell 3 inside.

In order to increase the reliability of locking, on shell 3, be formed with locating hole 18, be formed with the positioning convex 19 that cooperates with above-mentioned locating hole 18 and look outside on the cover 16.Certainly, the terminal end shape of positioning convex 19 also can be a hemispherical or conical, so that unlock.

In addition, case drawbar of the present invention also comprises chain assemblies in order to realize the function expansion; Specifically, chain assemblies comprises: be arranged on the handlebar stem 1 and expose a pair of connecting ring 20 of handle shell 5, be connected in the chain 21 on the connecting ring 20; Be used to hold the chain cover 22 of chain 21, be provided with magnet 23, its role is to hold chain 21 in chain cover 22 bottoms; Simultaneously, magnet 23 bottoms are provided with the chain cover fixed head 24 that is connected with case and bag.

As a kind of concrete structure, chain 21 is two, is arranged between a pair of flexible interior pipe 2, and equates with the close distance of stretching between the interior pipe 2.So,, in flexible, also be provided with two chains 21 between the pipe 2 when case drawbar is in when pulling out state, and a pair of flexible in distance between the pipe 2 also increased, can be used to place parcel or other luggage and articles, expand of great advantage to its function.

More than show and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand, and the foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
