Description
Technical field
The present invention relates to the case and bag accessory, especially relate to a kind of case and bag shock-absorbing universal wheel and case and bag that reduce the casing vibration.
Background technology
The special-purpose universal 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 universal 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 universal 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 universal wheel in other every field; Just often run in our life; Like the shock-absorbing universal wheel that aspects such as luggage truck, perambulator, go-cart are used, this shock-absorbing universal 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 universal wheel as yet.
?
Summary of the invention
Technical problem to be solved by this invention is, the case and bag shock-absorbing universal wheel that a kind of overall structure is strong, the shock-absorbing superior performance also can be exchanged wildcard with common universal wheel wheel seat is provided.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of case and bag shock-absorbing universal wheel comprises holder, supporting bracket, roller; Said roller is connected with supporting bracket through a transverse axis; Connect through a vertical pivot between said supporting bracket and the holder, the top of said vertical pivot is fixedly connected with holder, and said vertical pivot bottom turns with the axle installing 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 elastic device that stops table top to move downward on the said table top.
As a kind of improvement, said elastic device 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 supporting surface; Said supporting surface is provided with movable span, and said stage clip is arranged on the supporting 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 brace; Said brace is positioned on the transmission bracket away from an end of roller through hole, and said table top is arranged on the brace.
Because in the above-mentioned technical solution; Connect through vertical pivot between support and the holder, the top of said vertical pivot is fixedly connected with holder, and the vertical pivot bottom turns with the installing hole that the opening that support is provided with makes progress and cooperates; Such structure is very simple, production cost is low; Because vertical pivot and rotatable cooperation of axle installing hole, therefore only need when mounted to install very convenient with getting final product with holding in the palm be fixedly connected to reinstall in the installing 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 elastic device 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 elastic device; When roller because the weight of case and bag when causing roller to move upward relatively; Table top moves downward relatively, because the interception of elastic device makes the weight of case and bag and the active force of elastic device reach balance; Played the effect of shock-absorbing; Strong, the shock-absorbing superior performance of overall structure, and can exchange wildcard with common universal wheel wheel seat, can overcome existing universal wheel weak point, its appearance and size and structure reach the requirement of exchanging wildcard with common universal wheel wheel seat; Be applicable to the case and bag generic request, therefore roll wheel assembly provided by the invention have simple in structure, production cost is low, easy for installation, working (machining) efficiency is high, rotation is flexible, the characteristics of shock-resistant, long service life.
