Detailed Description

The following detailed description of the present patent application will be made with reference to fig. 1-3, and it should be noted that the present application is only an example of the preferred embodiments of the present patent application and should not be construed as limiting the scope of the present patent application.

The silence luggage case 1 is provided in the present embodiment, the luggage case comprises a case body, the case body is made of plastic, an outer frame and bottom feet are provided in the case body, a handle is provided at the rear part of the outer frame, and the handle is a telescopic handle 2. Further preferably, the whole frame is a cuboid or a cube and is provided with a front plate 3, a rear plate 4, a left side plate 5, a right side plate, a bottom plate and an upper cover, further, the front plate and the rear plate are made of a first strength material, the side plates are folding plates and are made of a second strength material, therefore, high strength is provided in the front plate and the rear plate to provide stable box body strength, the side plates can be folded to save space, and the whole strength is not influenced by folding.

The bottom of the box body is provided with four mounting seats 6, and the four mounting seats are preferably arranged at four corners of the box body respectively. It is particularly preferable to provide the front and rear plates with high strength to provide high strength for mounting the wheels.

Four wheels 7 are mounted at four corners 8 of the box body. Thus, the box body can be conveniently dragged. The wheels are preferably universal wheels, so that the flexible pushing device can be flexibly pushed under various terrain and weight conditions.

Because the suitcase of this patent is folding box, and its whole is made by plastics moreover, consequently, when dragging, produce great noise easily. Therefore, it has a high demand for the silencing of the wheels, and since such a case is frequently used for portability, it is required to have not only steering reliability and flexibility and better durability but also good damping and silencing effects on the wheels.

In this patent, the base is provided on the front and rear plates, thereby having high strength in material. The base includes recess 11, preferably, recess 11 opening sets up down, be provided with a plurality of archs on the wall inboard of recess 11, still be provided with at least one through-hole on the recess 11 wall, the through-hole is preferred two relative setting on the recess 11 wall.

The wheel with the base cooperation, detachably set up on the base, the wheel includes wheel hub 14, plastic wheel rim 13, wheel hub 14 is the disc on the whole, plastic wheel rim 13 is solid plastic layer, and preferably whole cladding is in wheel hub 14's outer lane, in this embodiment, be provided with plastic strip 15 in the plastic layer, plastic strip 15 includes the follow the plastic layer to first branch and second branch that extend in wheel hub 14. The first and second prongs are fixedly connected to the hub 14. The vibrations of the hub 14 are thus absorbed in the outer ring and the hub 14 by the soft plastic material and the plastic material embedded in the hub 14, so that the transmission of the vibrations from said hub 14 to the box is reduced, reducing the sound during dragging.

Preferably, the plastic strip 15 is Y-shaped, and two strips extending inward from the plastic rim 13 further extend inward along a radius of the hub 14.

The wheels are preferably of a coaxial double-wheel design, the double wheels have the same structure, the middle parts of the double wheels are connected through a first shaft 9, a first bearing is arranged on the periphery of the first shaft 9, and the first bearing and the first shaft 9 are arranged in the left-right direction. The wheel further comprises a second bearing and a second shaft 10, the second bearing is fixedly connected with the first bearing, the second bearing 10 and the second shaft 10 are arranged in the vertical direction, a head matched with the base is arranged on the second shaft 10, a groove 11 is formed in the head, the groove 11 is matched with a convex block on the base to provide positioning use, two elastic sheets are arranged on the side edge of the head, a raised head 12 is arranged on each elastic sheet, and the raised head 12 is matched with the hole 6 in the base to clamp the head on the base.

The two-wheel structure provides a stable structure with a hollow between the two sides to reduce the actual contact with the ground. Reducing resistance and vibration. In this patent, the first shaft 9 extends in one direction and the second shaft 10 extends in a second direction, and rotation along both axes may cause the wheel to act as a universal wheel.

Further, in this patent, the universal wheel still preferably includes brake equipment, brake equipment is including setting up draw-in groove 16 of 14 inboards of wheel hub, and the pivot setting is in lever on first bearing and the second bearing, the one end of lever is provided with horizontal card strip, the tip of card strip with draw-in groove 16 cooperation, the middle part and the elastic arm cooperation that sets up on first bearing of card strip, work as the card strip is gone into the in-process of draw-in groove 16, the card strip confronts the elasticity of elastic arm and moves, work as the card strip is gone into behind draw-in groove 16, the elastic arm relies on elasticity to be with the card strip keeps in draw-in groove 16. The other end of the lever is provided with a block, so that the operation of an operator is facilitated. Through the structure, the locking with stability and reliable strength can be completed through a simple plastic part.
