The working principle of the luggage case in actual use is as follows:

when the luggage case is not required to be dragged, a user operates the pull rod 5 to put down, the push rod 16 connected with the pull rod 5 is pushed down to the bottom along with the putting down of the pull rod 5, one end, far away from the pull rod 5, of the push rod 16 is abutted against the boss 13 along with the pressing down, the bayonet lock structure 12 is pushed to slide downwards, the bayonet lock structure 12 sliding downwards is inserted into the tooth groove 11 annularly formed in the inner side wall of the hub 1 in a matched mode, and braking can be achieved.

When the pull rod 5 is in a down state, the limiting pin 52 arranged on the side surface of the outer tube 51 can pop out in the box body 4 to be matched with the limiting hole for limiting, namely, the pull rod 5 is limited and fixed; at this time, the detent structure 12 slides downwards to be matched with the tooth socket 11 for limiting, the return spring 15 in the window 14 is pressed, once a user presses the release button 53 to release the limiting of the pull rod 5 to pull up the pull rod 5, the detent structure 12 without being pressed by the push rod 16 returns back under the action of the return spring 15, the detent structure 12 slides upwards to be separated from the tooth socket 11, and the brake mechanism releases braking.

The pull rod 5 is used as the control part of the push rod 16, and the advantage is that when a user does not need to drag the luggage case, the pull rod 5 can be naturally put down, and the brake mechanism is put down by the pull rod 5, so that the brake is realized; when a user wants to drag the luggage case, the pull rod 5 is naturally pulled up, and the brake mechanism is pulled up by the pull rod 5 to release the brake; so, pull rod 5 is given a plurality of functions, and the suitcase need not to set up other switches again for realizing the braking wantonly, and the suitcase is whole more succinct, and the user operation is also more simple and convenient.

When the pull rod 5 is put down, the polygonal push head 161 and the polygonal groove 131 are inserted in a matching manner to act, that is, as the push rod 16 is pressed down along with the putting down of the pull rod 5, one end of the push rod, which is far away from the pull rod 5, is abutted against the boss 13, and the corresponding polygonal push head 161 is inserted into the polygonal groove 131 on the boss 13 to realize matching and limiting; because the push rod 16 can only slide up and down and cannot rotate in the horizontal direction, the lug boss 13 matched with the push rod for limiting is naturally locked and cannot rotate in the horizontal direction, and further, the wheels are locked and cannot rotate; so set up and make the suitcase put down the back at pull rod 5, can not only realize the braking to wheel hub 1, make it can not roll, still turn to it simultaneously and lock, make the wheel realize locking in the true sense.

This steering locking unit only cooperates spacing realization through the polygon recess 131 that corresponds to seting up on polygon pushing head 161 that sets up in push rod 16 one end and boss 13 and turns to the locking, and this setting makes push rod 16 have multinomial function and simple structure, compares in using the cooperation of a plurality of complicated spare parts to realize this function, and this setting is not fragile stability more higher.

The arrangement of the push rod elastic member 162 increases the buffering between the upper push rod and the lower push rod, and the premise that the bayonet lock structure 12 is matched and limited with the tooth socket 11 is that the bayonet lock structure 12 corresponds to the tooth socket 11, and once the bayonet lock structure 12 does not correspond to the tooth socket 11, the bayonet lock structure 12 is supported by the spacing part between the tooth sockets 11 to cause the sliding failure, so that the integrated push rod 16 cannot smoothly push the bayonet lock structure 12 to slide down.

The push rod 16 is arranged to be a split structure consisting of an upper push rod and a lower push rod, and a push rod elastic part 162 for buffering is arranged between the upper push rod and the lower push rod, when the bayonet lock structure 12 does not correspond to the tooth grooves 11, a user operates the push rod 16 to press down, although the bayonet lock structure 12 is supported by the spacing parts between the tooth grooves 11 and can not slide down, the upper push rod can still be pressed down due to the compression of the push rod elastic part 162 between the upper push rod and the lower push rod, so that the illusion that the brake mechanism fails and can not be pressed down is not caused to the user, and the use feeling is improved; meanwhile, the push rod elastic element 162 compresses to store energy, and when the hub 1 rolls to the position where the tooth grooves 11 are matched with the bayonet lock structure 12, the bayonet lock structure 12 can be bounced into the tooth grooves 11 to be matched and limited under the tension action of the push rod elastic element 162.

Example 2

The difference between this embodiment and embodiment 1 is that in this embodiment, only one wheel on the bottom of the box 4 is the wheel with the brake mechanism, as shown in fig. 9.

In this embodiment, the operating member at one end of the push rod 16 is a push rod presser 6, as shown in fig. 7 and 9.

The push rod pressing piece 6 is provided with a pressing piece limiting seat 61 matched with the push rod pressing piece, as shown in fig. 8.

The push rod presser 6 is connected to one end of the push rod 16, and has a projection 62 formed on the inner side thereof, as shown in fig. 7.

A sliding block 64 is arranged on one side of the pressing part limiting seat 61, and the sliding block 64 can push towards the inner side of the pressing part limiting seat 61; a clamping groove 63 is formed at the joint of the pressing part limiting seat 61 and the sliding block 64, as shown in fig. 8.

The slider 64 is provided with a spring, the spring is positioned in the pressing part limiting seat 61, one end of the spring is abutted against the slider 64, the other end of the spring is abutted against the inner side wall of the pressing part limiting seat 61, and the spring can enable the slider 64 to reset and rebound.

The side of the sliding block 64 far away from the pressing piece limiting seat 61 is an arc surface 65, as shown in fig. 8.

The operating principle of the operating control piece in the using process is as follows:

the user presses the push-rod presser 6, and the push rod 16 is pressed accordingly.

After the push rod pressing piece 6 is pressed downwards, the convex block 62 on the inner side wall of the push rod pressing piece presses the arc surface 65 of the sliding block 64 downwards, and the sliding block 64 can horizontally slide towards the inner side of the pressing piece limiting seat 61 in a translation manner (namely the arrow direction shown in fig. 8) under the extrusion of the convex block 62, so that a space is reserved for the convex block 62 to downwards; when the bump 62 is pressed downwards to correspond to the clamping groove 63, the sliding block 64 is not abutted by the bump 62 any more, the sliding block 64 can rebound and reset under the action of the spring, so that the sliding block 64 limits the bump 62 above the clamping groove 63, and the pressed push rod pressing piece 6 is matched with the pressing piece limiting seat 61 for limiting under the matching limit of the bump 62 and the clamping groove 63.

When the brake mechanism needs to be unlocked, a user only needs to push the sliding block 64 to slide in a translation mode towards the inner side of the pressing part limiting seat 61, so that the top of the protruding block 62 is not limited by the sliding block 64, after the push rod pressing part 6 loses limitation, the reset spring 15 on the clamping pin structure 12 has no limitation, the reset spring rebounds to enable the clamping pin structure 12 to be separated from the tooth groove 11, the unlocking of the brake mechanism is further achieved, and meanwhile, the push rod pressing part 6 losing limitation can be bounced up along with the push rod 16 by the reset spring 15.

In this embodiment, the polygonal pushing head 161 and the polygonal groove 131 are triangular.

In this embodiment, the push rod elastic member 162 is a spring.
