The specific embodiment

As shown in Figures 1 to 4, the flexible castor of the utility model pull bar baggage container and knapsack mainly comprises: a hub 10, wheel seat 20, brake equipment 30 and decontrol 40; Wherein, this hub 10 is to be installed on the baggage container 100, this hub 10 is provided with a chute 11, the x of these chute 11 relative these baggage containers 100 axially and the axial face that constitutes of z be to be a tipper, so design can make overall space structure and operational benefits reach optimum regime, certainly, the x that is located at this baggage container 100 in these hub 10 conversion is axially and on the axial face that constitutes of y the time, the x of these chute 11 relative these baggage containers 100 axially and the axial face that constitutes of y also be to be a tipper, in other words, the face that is provided with of these chute 11 relative these baggage containers 100 is to be a tipper; This chute 11 is provided with an opening 13 that reaches along chute 11 directions in order to spacing backplate 12, is to be provided with a groove 14 on the face of this chute 11, and the bottom of this groove 14 has a follow block 15 and the appropriate location is provided with cooresponding open-work 16; The appropriate location of these hub 10 medial surfaces is provided with a screw 17, the intrinsic position-limited lever 18 of these screw 17 spiral shells, and in addition, chute 11 medial surfaces of this hub 10 are provided with plural locking part 19 (as spiral shell spare or riveting parts etc.), in order to be consolidated on this baggage container 100.

This wheel seat 20 is to be the chute 11 of slidably being located at this hub 10, this wheel seat 20 is provided with a recess 21, this recess 21 is provided with an axis hole 211, this recess 21 is in order to a wheel body 22 to be set, and mat one axis bar 221, latch fitting 222 and pad 223,224 be hubbed at this axis hole 211 places with this wheel body 22, and this wheel body 22 is rotated freely; The end in addition of these wheel seat 20 relative these wheel bodys 22 is provided with one and is relative outer groove 23 and inner groovy 24, and this

outer groove

23 and 24 of inner groovies are to link a perforation 25 is arranged; The one side of these wheel seat 20 relative these chutes 11 is provided with an arrival slot 26, one end of these arrival slot 26 nearly these axis holes 211 is to be provided with one to support face 261, the other end that this arrival slot 26 should support face 261 relatively then is provided with an inclined-plane 262, again, the position-limited lever 18 of these wheel seat 20 relative these hubs 10 is the position-limited troughs 27 that are provided with a long groove shape, this position-limited lever 18 also stretches in this position-limited trough 27, in order to provide this wheel seat 20 in this chute 11 movable stroke space and prevent this wheel seat 20 detach this hub 10 (shown in Fig. 5 A, 5B).

This brake equipment 30 is groove 14 places that are located at this hub 10, this brake equipment 30 includes a brake component 31 and first spring 32, the outside of the other end of these brake component 31 relative these openings 13 is to be provided with an inclined-plane 311, and the inboard of this brake component 31 is to be provided with a recessed tank 312 and bottom to be provided with end hook part 313, when this brake component 31 is located at this groove 14, this first spring 32 is to be located in this recessed tank 312 and to be butted on this follow block 15, and this end hook part this open-work 16 of 313 mats catches on this hub 10 medial surfaces, is pushed up from taking off this groove 14 by this first spring 32 to prevent this brake component 31.

This decontrol 40 includes a push button element 41, second spring 42 and button latch fitting 43, this push button element 41, second spring 42 are to be located at this outer groove 23, this button latch fitting 43 is to be located at this inner groovy 24, and this perforation 25 of mat makes this button latch fitting 43, push button element 41 lock knot (as the spiral shell knot) mutually, make this push button element 41 be limited in this outer groove 23, and replaced by 42 elasticity of this second spring.

As Fig. 5 A, shown in 6A and the 7A, when baggage container castor during in running condition, this wheel body 22 is to protrude out outside the opening 13 of this chute 11, this brake component 31 was replaced by first spring 32 and was stretched into this inner groovy 24 this moment, and correspondence touches this button latch fitting 43, and because of this wheel seat 20 be to utilize this position-limited trough 27 spacing and support by 18 of this position-limited levers, so this wheel seat 20 can't drop out toward these opening 13 directions, on the other hand, because the inner groovy 24 of this wheel seat 20 is braked by this brake component 31, so make at these wheel body 22 kiss the earths, this wheel seat 20 does not contract in not understanding yet.

Shown in Fig. 7 B, when desire to carry out the baggage container castor in when contracting operation, promptly push this push button element 41, and mat is pressed into this brake component 31 in this groove 14 by this button latch fitting 43 of interlock, even this brake component 31 does not protrude out (being again groove 14 outsides) on this chute 11, the inner groovy 24 of this wheel seat 20 is owing to remove by the braking of this brake component 31 at this moment, so this wheel seat 20 can be pushed away by interior, and make in the opening 13 of this this chute 11 of wheel body 22 retractions, promptly finish the baggage container castor in the operation of contracting, as Fig. 5 B, shown in Fig. 6 B and Fig. 7 C, and this brake component 31 was acted on by this first spring 32 and was resisted against the arrival slot 26 of this wheel seat 20 this moment, and this wheel seat 20 is placed in this chute 11.

The utility model is seen it with technical characterictic, being about to this brake component 31 is located between this hub 10 and the wheel seat 20, and these wheel seat 20 relative these brake components 31 are provided with one at least in order to can be by the second place of application of force displacement (i.e. these arrival slot 26 positions) by the motionless primary importance of these brake component 31 blockings (i.e. these inner groovy 24 positions) and, certainly, when this brake component 31 was equipped in the primary importance of this wheel seat 20, pressing operation that must this push button element 41 of mat just can be removed the braking mode of this wheel seat 20.

Please consult Fig. 7 B and Fig. 7 C simultaneously, when down being pushed, this push button element 41 can impose an application of force that makes progress simultaneously, this wheel seat 20 is raised and this chute 11 of interior retraction, in other words, on contracting and operate, the utility model can only use can finishing of (as a thumb) on the other hand by pushing away in this wheel body 22, and convenient quite rapidly.

When desiring to carry out the transferring of this wheel body 22, promptly promote this wheel seat 20 or wheel body 22 and down get final product, preferable promotion position is at this push button element 41 or this axis bar 221 places, shown in Fig. 7 C, so can avoid contacting this wheel body 22 and prevents that hand is by dirty; Because when this brake component 31 is resisted against the arrival slot 26 of this wheel seat 20, it is the inclined-plane 262 that is inclined-plane 311 corresponding these arrival slots 26 of contact of this brake component 31, so in application of force operation, can facility press down this brake component 31, slide toward opening 13 directions of this chute 11 and make this wheel seat 20 be removed by the resistance of this brake component 31, and then this wheel body 22 is protruded out, shown in Fig. 7 A.

Based on of the present utility model above-mentioned old sensible by, the flexible easy operation of castor mat of the utility model pull bar baggage container, knapsack can be rapidly and is carried out the flexible start of wheel body easily, and dirt that effectively the castor wheel body is contacted with ground and human body are isolated, and then prevent that human body or clothes are by dirty, really be one quite the wound of excellence think, the whence proposes utility application in accordance with the law; Only holding within the above-mentioned explanation, only be that the preferred embodiment of the utility model illustrates, all variations of extending according to the technological means of the utility model also all should fall into the patent claim of the utility model.
