Description

Case and bag shock-absorbing cardan wheel

Technical field

The utility model relates to the case and bag accessory, especially relates to a kind of case and bag shock-absorbing cardan wheel and case and bag that reduce the casing vibration.

Background technology

The special-purpose cardan wheel of existing common case and bag can make case and bag in same plane, move towards any direction, thereby has saved people's muscle power, has made things convenient for the transportation of luggage.Though the tradition cardan wheel is of a great variety, structure also is not quite similar, and not possessing basically has incabloc function, and the sense of discomfort that therefore can cause the vibrations of user's hand when towing to bring especially running into when getting out of a predicament or an embarrassing situation, causes the damage of article in casing and the case easily.For solving existing defective, the case and bag cardan wheel that be necessary to design a kind of low noise, dependable performance, has an incabloc function solves the demand.Have now and be widely used in the shock-absorbing cardan wheel in other every field; Just often run in our life; Like the shock-absorbing cardan wheel that aspects such as baggage car, perambulator, go-cart are used, this shock-absorbing cardan wheel is owing to this complex structure, and volume is too huge; Manufacturing cost is corresponding wants high, so can not be applicable to the case and bag class.In the prior art, through retrieval, case and bag are not also found with the shock-absorbing cardan wheel as yet. ?

Summary of the invention

The utility model technical matters to be solved is, the case and bag shock-absorbing cardan wheel that a kind of overall structure is strong, the shock-absorbing superior performance also can be exchanged wildcard with common cardan wheel wheel seat is provided.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of case and bag shock-absorbing cardan wheel comprises holder, supporting bracket, roller; Said roller is connected with supporting bracket through a transverse axis; Connecting through a vertical pivot between said supporting bracket and the holder, captives joint with holder in the top of said vertical pivot, and said vertical pivot bottom turns with the axle mounting hole that supporting bracket top is provided with and cooperates; It is characterized in that: also be provided with transmission bracket; Said transmission bracket is provided with roller through hole, installation through holes, and said supporting bracket is rotationally connected through installation through holes and transmission bracket, and said roller is connected with transmission bracket through a transverse axis is set in the roller through hole; A sidepiece relative with the roller through hole on the said transmission bracket is provided with table top, is connected with the springing that stops table top to move downward on the said table top.

As a kind of improvement, said springing comprises stage clip, last item, and said last item two ends are respectively arranged with first boss, second boss; Said supporting bracket is provided with bearing surface; Said bearing surface is provided with movable span, and said stage clip is arranged on the bearing surface and is positioned at the movable span top, and said last item passes movable span and cooperates with an end of stage clip through first boss; Said table top is provided with the table top through hole, and second boss of said last item cooperates with the table top through hole lower surface of table top.

As a kind of improvement; Spacing hour between said roller and the supporting bracket; Said movable span has the activity space that holds last item; Said activity space longitudinal cross-section is away from a side and the spring center parallel axes of roller, and another side of said activity space longitudinal cross-section and supreme downward direction are away from the spring center axis.

As a kind of improvement; Said roller through hole is positioned at a side of installation through holes; Said table top is positioned at the opposite side of installation through holes; Said installation through holes, table top and roller through hole increase to ground distance successively, and said installation through holes center is arrived installation through holes centre distance to table top centre distance less than the roller through hole.

Said transmission bracket is provided with first driver blade and second driver blade of shape symmetry; Said first driver blade laterally arranges with second driver blade and is connected through connecting strap; Said connecting strap is positioned on the transmission bracket away from an end of roller through hole, and said table top is arranged on the connecting strap.

Because in the above-mentioned technical solution; Connecting through a vertical pivot between support and the holder, captives joint with holder in the top of said vertical pivot, and the vertical pivot bottom turns with the axle mounting hole that the opening that support is provided with makes progress and cooperates; Such structure is very simple, productive costs is low; Cooperates because vertical pivot and axle mounting hole are rotatable, therefore only need when mounted to install very convenient getting final product with holding in the palm captive joint to reinstall in the axle mounting hole on the vertical pivot; Supporting bracket is connected with transmission bracket through transverse axis is set in installation through holes, and roller is connected with transmission bracket through transverse axis is set in the roller through hole, and a sidepiece relative with the roller through hole on the transmission bracket is provided with table top; Be connected with the springing that stops table top to move downward on the table top; Transmission bracket is equivalent to drive link, and an end connects roller, and the other end connects springing; When roller because the weight of case and bag when causing the relative upward movement of roller; Table top moves downward relatively, because the interception of springing makes the weight of case and bag and the application force of springing reach balance; Played the effect of shock-absorbing; Strong, the shock-absorbing superior performance of overall structure, and can exchange wildcard with common cardan wheel wheel seat, can overcome existing cardan wheel weak point, its oad and structure reach the requirement of exchanging wildcard with common cardan wheel wheel seat; Be applicable to the case and bag generic request, thus the roll wheel assembly that provides of the utility model have simple in structure, productive costs is low, easy for installation, work efficiency is high, rotation is flexible, the characteristics of shock-resistant, long service life.

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to describe.
