Description

A kind of case drawbar with locking combination

Technical field

The present invention relates to case drawbar a kind of and lock combination.

Background technology

Without the lock of lock case drawbar, very inconvenient in consumer's use procedure on the case and bag of tradition with pull bar, in the time that needs leave case and bag, can not be fixed and lock in somewhere, cannot be antitheft; Or in the time case and bag being placed on the environment of a motion as the car travelling, being positioned over case and bag on luggage carrier and acutely rocking landing sometimes because of car, dangerous, also affect service life of case and bag.

Summary of the invention

Technical problem to be solved by this invention is to provide case drawbar a kind of and lock combination, can will case and bag be locked on a fixture by pull bar at any time, prevents case and bag displacement or stolen, facilitates consumer to use.

For solving the problems of the technologies described above, the invention provides case drawbar a kind of and lock combination, it is characterized in that, comprise a case drawbar, one is arranged on described case drawbar and the lock that can freely take off, described lock is installed in the groove of pull bar upper cover formation, and be stuck in described pull bar upper cover by a mobilizable connecting plate, described lock is coded lock, is wound with retractable tightwire wire in lock, after one folding and unfolding end pull-out of described tightwire wire, locked in a hole thereon by described lock.

The inside of described lock comprises is located at the character wheel that character wheel puts, and also comprises an axle center of being controlled by described character wheel, character wheel cover, and described axle center is provided with one can hold the through hole that described tightwire wire folding and unfolding end passes through; Also comprise one with the bail of the adjacent setting in described axle center, described bail inserts in the connecting plate of a motion movingly; Also comprise one can axial rotation ratchet, described tightwire wire one stiff end is wound on a ratchet; One end of one take-up button is provided with the ratchet coordinating with described ratchet.

Described connecting plate promotes transverse movement by button and inserts in described pull bar upper cover.

Promote the position that described take-up button to described ratchet separates with described ratchet, described ratchet rotates counterclockwise emits described tightwire wire.

In described lock, also comprise the reversion button that initial password is set or resets password.

Described tightwire wire folding and unfolding end is stuck in described lock by described axle center by described through hole.

The beneficial effect that the present invention reaches:

Of the present invention with lock combination case drawbar by former traditional case drawbar function be locked into row set, consumer is used more convenient, reduce use in puzzlement.Can directly use the line operate that is locked in current trolley luggage; It is fixing that personnel can not use lock of the present invention that case and bag and periphery fixture are locked in the time of case and bag side, prevents that the stolen or case and bag of case and bag are shifted, slip etc. because of collision.Lock can take off from case drawbar, independent use, and it is greatly convenient to have brought to user.

The specific embodiment

Below in conjunction with accompanying drawing, the invention will be further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.

As shown in Figure 1 and Figure 2, when user pulls out pull bar aluminum pipe 20 by pull bar handgrip group 21, in the groove that forms of pull bar upper cover 22 on the case drawbar of of the present invention and lock combination, a lock that can freely take off 1 can be installed, pull bar upper cover 22, bracket base 23 are fastened on respectively on case and bag, for ease of explanation, not shown case and bag in the present embodiment.In the time that needs lock in case and bag on one fixture, pull out a tightwire wire 12 from locking in a hole of 1, on a fixture, and tightwire wire 12 is locked in another hole of 1.

Lock 1 is involuted by lock housing A2, lock housing B3, its inside comprises: be located at the rotation character wheel 4 on character wheel cover 5, initial password is set or resets the reversion button 7 of password, can move downward the bail 13 inserting in connecting plate 8, connecting plate 8 can be promoted to carry out transverse movement by button 14, also comprises an axle center 6, and axle center 6 is provided with one can pass through the through hole of tightwire wire 12, tightwire wire 12 is wound on ratchet 9, and one end of take-up button 11 is provided with the ratchet 10 coordinating with ratchet 9.When ratchet 10 is stuck in ratchet 9, ratchet 9 is driven and is clockwise rotated by the active force of back-moving spring, automatically the tightwire wire of pull-out 12 is regained wound on it; In the time that promotion take-up button 11 moves downward, ratchet 10 separates from ratchet 9, now, can pull tightwire wire 12 to drive ratchet 9 to rotate counterclockwise, and makes tightwire wire 12 pull-out from lock.

Structure lock internal structure Figure 11 illustrates that it is unblanked, locking process below.

When locking, rotation character wheel 4, when original state in the correct situation of password as shown in Figure 3, take-up button 11 is moved down the ratchet 10 of take-up button 11 lower ends is departed from from ratchet 9, stopping of ratchet 9 pawl-less 10 can rotate counterclockwise, and now pulls tightwire wire 12 as shown in Figure 4; Tightwire wire 12 is buckled in axle center 6, as shown in Figure 5; Tightwire wire 12 promotes bail 13 simultaneously and moves downward, snaps in connecting plate 8, and the transverse movement of restriction connecting plate 8, rotation character wheel 4 carries out locking, and tightwire wire 12 is lockable, and cannot open;

While unblanking, rotation character wheel 4, when in the correct situation of password, is moved to the left axle center 6 to realize unlocking function, as shown in Figure 6.

The schematic diagram that lock packs pull bar into is as shown in Fig. 1, Fig. 7, Fig. 8, and connecting plate 8 can snap in pull bar upper cover 22 automatically, and after locking, connecting plate 8 laterally cannot move, therefore lock 1 cannot be from the interior taking-up of pull bar upper cover 22; As shown in Figure 9, Figure 10, after unblanking, button 14 is moved to the left, drives connecting plate 8 to left movement, connecting plate 8 is from the interior disengaging of pull bar upper cover 22, and lock can freely take out from pull bar.

The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
