Detailed Description

In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only used for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the designated device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

A wear-resistant portable draw-bar box is disclosed, as shown in figures 1-3, comprising a box body 1 and a telescopic draw-bar 2, wherein the bottom of the box body 1 is provided with a bearing plate 3 for bearing the box body 1, the box body 1 and the bearing plate 3 are made of polyamide plastics, the polyamide plastics have the characteristics of high strength and wear resistance, the wear on the appearance can be reduced while the protection on the box body 1 and the bearing plate 3 is increased, the service life is prolonged, the bearing plate 3 is rotatably connected with a screw rod 4 which penetrates through the box body 1 and wraps the telescopic draw-bar 2, the box body 1 is in threaded connection with the screw rod 4, the telescopic draw-bar is in sliding connection with the screw rod 4, universal wheels 5 are arranged at the bottoms of the bearing plate 3 and the box body 1, the bearing plate 3 is rotatably connected with a sleeve 6, the sleeve 6 is provided with rollers 7, the box body 1 is provided with a clamping groove 8 for accommodating the rollers 7 and limiting the rollers 7, after articles are carried by using the product, because the driving wheel 9 is arranged between the screw rod 4 and the bearing plate 3, the bearing plate 3 is externally connected with the pushing piece 10 with the tooth 11 in a sliding way, the pushing piece 10 is meshed with the driving wheel 9, when going upstairs, the pushing piece 10 at the bottom of the bearing plate 3 is only needed to move to drive the driving wheel 9 to rotate, and the driving wheel 9 drives the screw rod 4 to rotate when rotating, and the box body 1 in threaded connection is moved upwards, after the box body 1 is moved upwards, the bearing plate 3 is not moved, the universal wheel 5 at the bottom of the bearing plate 3 is not moved, and the gravity is also lifted along with the box body 1 after moving upwards, the telescopic pull rod 2 is lifted at the moment, the roller 7 and the sleeve 6 on the bearing plate 3 are separated from the clamping groove 8, at the moment, the sleeve 6 on the bearing plate 3 can be rotated to drive the roller 7 to move outwards, therefore, when a user drags the box body 1 to move, the universal wheel 5 at the bottom of the lining plate can still contact with the ground to roll, when the user needs to go upstairs, the idler wheels 7 are located on the side face of the box body 1, at the moment, when the box body 1 is pushed, the idler wheels 7 on the side face of the box body 1 can be in contact with the vertical faces of the steps, and the universal wheels 5 are in contact with the horizontal face, so that the user does not need to lift the box body 1 to play a labor-saving effect when going upstairs, and the situations that the user is inconvenient to lift and is hard due to excessive and overweight articles in the box body 1 are avoided.

A plurality of teeth 11 are arranged on one side of the sleeve 6 far away from the roller 7, a lug 12 which is engaged with the teeth 11 and pushes the sleeve 6 to rotate is arranged on the box body 1, a torsion spring 13 is arranged between the sleeve 6 and the supporting plate 3, and after the box body 1 moves upwards, the sleeve 6 and the roller 7 are separated from the clamping groove 8, at the moment, the torsion spring 13 between the sleeve 6 and the supporting plate 3 pushes the sleeve 6 to rotate and drive the roller 7 to rotate to the outside of the side surface of the box body 1, so that the sleeve 6 is automatically popped out when the box body 1 moves upwards without manual driving, and when the box body 1 moves downwards and resets, the lug 12 on the box body 1 can be abutted against and engaged with the teeth 11 on the sleeve 6, therefore, when the box body 1 moves downwards, the effect of reverse reset of the sleeve 6 is driven by the lug 12 and the teeth 11, and the torsion spring 13 is compressed when the sleeve 6 rotates reversely and resets, therefore, the sleeve 6 and the roller 7 can still be automatically ejected when the box body 1 is used next time, the effect of automatic retraction is achieved, the compression spring 14 is arranged between the sleeve 6 and the roller 7, when the box body 1 is dragged to move along the steps, the fall feeling is generated when the first-grade steps rise, therefore, after the roller 7 moves to the horizontal plane of the steps along the vertical plane, the universal wheel 5 can rapidly move along the horizontal plane due to gravity and inertia, the roller 7 can be impacted and the box body 1 can be impacted, at the moment, the roller 7 is compressed along the compression spring 14 under the impact gravity, the impact force is reduced, the shock absorption effect is achieved, the pull plate capable of pulling down and closing the sleeve 6 and the roller 7 is arranged on the side surface of the box body 1, after the sleeve 6 is driven by the box body 1 to rotate to be embedded into the clamping groove 8, at the moment, the situation that the sleeve 6 and the roller 7 can not be completely closed by the box body 1 is avoided, at this time, the pulling plate can be pulled down to close the sleeve 6 and the roller 7, so that the gold can achieve the effect of attractive appearance, and the sleeve 6 and the roller 7 cannot be used perfectly due to the contamination.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
