Luggage roller

Technical Field

The utility model belongs to the technical field of the case and bag, a rim structure is related to, especially a case and bag gyro wheel.

Background

The existing luggage on the market generally comprises a luggage body, a pull rod and rollers. The bottom of the box body is provided with a bottom support as a connecting piece of the roller and the box body. The function of the pull rod is to pull the box to cause the box to move under the driving of the rollers. The box body is generally provided with a handle above the box body, so that the box body can be lifted through the handle on a road surface where the box is not convenient to push.

The current box body structure has the problem that the bearing capacity and the strength of the bottom support are not enough, and meanwhile, the manufacturing materials are not enough, so that the box body structure is light and convenient. In addition, the wear of the wheels is the most serious in all parts of the luggage, and in the wheel structure, the wheel skin positioned on the outer layer and contacted with the ground is easy to wear and age, once the surface layer of the wheel skin is damaged, the whole luggage body cannot be dragged on the ground, and the using effect of the whole luggage is influenced. The wheel skin of wheel can't be changed conveniently to current case and bag structure.

SUMMERY OF THE UTILITY MODEL

The utility model aims at having the above-mentioned problem to current technique, provided an increase supplementary wheel skin disassembly body in the wheel to the case and bag gyro wheel of operation is changed to the wheel skin to the convenience.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a case and bag gyro wheel, is including the collet skeleton that is the rectangle, all install the gyro wheel on the bottom surface four corners of collet skeleton, the collet skeleton has the back and front, the back is the bearing surface, set up the high wheel back between the back of collet skeleton and the gyro wheel, set up the low wheel back between the preceding front of collet skeleton and the gyro wheel, the gyro wheel includes wheel hub and wheel skin, set up the combination groove in the wheel hub, set up driving piece, spring and executive, the bottom suppression spring of driving piece, the driving piece has the face that pushes away that is the slope, the executive has the slide that is the slope after the spring is pushed down to the driving piece, push away the face contact the slide and progressively pass and make executive outer end stretches out behind the combination groove jack-up the wheel skin.

In this case and bag gyro wheel, the atress direction of collet skeleton is high wheel back to increase intensity, and non-atress direction is low wheel back, with save material. If the wheel skin of this case and bag gyro wheel suffers serious wearing and tearing, the manpower inwards presses the driving piece, through the driving piece push away the face and the smooth surface of executive component contacts gradually, utilizes the inclined plane to promote the outward travel of executive component, stretches out wheel hub and jack-up the wheel skin until executive component outer end, produces great clearance between wheel skin and the wheel hub from this to make things convenient for use of tool to lift the wheel skin off. Then, a new wheel skin is sleeved on the wheel hub, the wheel skin compresses the actuating piece to enable the actuating piece to reset to the combined groove under the condition that no external force is exerted, and the actuating piece moves outwards to the initial position under the action of the elastic force of the spring.

In the case roller, the high-wheel back bag comprises an angle seat, the roller is installed below the angle seat, a bearing plate is erected on the back side of the angle seat, and the bearing plate is located in the back surface.

In the case roller, the low-wheel back comprises an angle seat, and the roller is arranged below the angle seat.

In the case roller, the hub is provided with a plurality of array holes, and the array holes are annularly arranged.

In the case roller, the actuating member is a straight rod, the inner end face of the straight rod is a sliding face, the driving member is in a right-angle shape, the vertical edge of the right-angle shape is a button rod, the transverse edge of the right-angle shape is a driving rod, and the outer end face of the driving rod is the pushing face.

In the case roller, the combination groove comprises a mounting groove and a sliding groove which are communicated, the spring and the driving piece are placed in the mounting groove from bottom to top, the top end of the torsion bar extends out of the mounting groove to form an exposed end, the straight bar is placed in the sliding groove, and the outer wall of the straight bar is in sliding contact with the inner wall of the sliding groove.

In the case roller, the notch of the mounting groove is provided with a blocking edge, the outer wall of the torsion bar is provided with a limiting block, and the limiting block and the blocking edge form corresponding abutting contact. When the driving piece is jacked up by the elastic force of the spring, the limiting block is abutted and contacted with the blocking edge to prevent the driving piece from falling off or misplacing; when the driving piece is pressed down by manpower, the limiting block is separated from the blocking edge.

Compared with the prior art, the case roller has the following advantages:
