Abstract
The utility model discloses a universal wheel, comprising a supporting rack, a big ball body, a small ball body, an isolation ring, and a supporting board. The big ball body is in the middle, the supporting rack is arranged on the big ball body, and on the upper part of the supporting rack, a connecting handle is provided. The connecting handle is divided in two parts, on the lower part, a cylinder is provided, and on the upper part, a cylinder with the minor diameter and a screw thread is provided. The connecting handle is used to connect with the carriage, etc. On the lower part of the supporting rack, four sub-supporting racks are provided, and shaped of circular arc. The big ball body is wrapped by the four sub-supporting racks. At the bottom of each sub-supporting rack, the supporting board is evenly provided. The supporting board is connected with the connecting handle and the supporting rack. At the bottom of the each sub-supporting rack, a groove is evenly provided. The grooves of four supporting rack are intersected in the upper part of the supporting rack and communicated mutually. In each groove, three small ball bodies are provided, when the universal wheel steers, the big ball body is static in the original place. Rotating the supporting rack in the arbitrary direction drives the smallball body to rotate in the surface of the big ball body and realizes the steering. The universal wheel solves the defect of not steering in the original place for the universal wheel, and the steering is convenient. The universal wheel is used for the carriage, the rotating seat, etc.
Description
Affiliated technical field
The utility model relates to a kind of cardan wheel.
Background technology
At present the general-duty cardan wheel all is that common wheel and turning cylinder are formed by connecting basically, though can reach the purpose that turns to all directions, the wheel segment distance that need move when turning to is if use very inconvenient at narrow space.
Summary of the invention
The purpose of this utility model is that a kind of cardan wheel that can conveniently turn to will be provided.
The purpose of this utility model can realize by following measure:
A kind of cardan wheel, centre are the very big and big spheroid of smooth surface of a hardness, and this spheroid can be made with the big plastics of steel, alloy or intensity, for saving in material also can be made hollow.The effect of big spheroid is as wheel, makes the cardan wheel motion.On the big spheroid support is arranged, support top is a connection handle.Connection handle is divided into two parts, and the bottom is a cylinder, and top is the less and screwed cylinder of a diameter, and connection handle is used for being connected with dolly etc.Four sub-stents are arranged at the support bottom, and they are circular arc, in the middle of big spheroid is wrapped in.All there is a stay bearing plate each sub-stent following, and stay bearing plate is connected with support with connection handle, has increased the intensity of support.All there is a groove each sub-stent following, and the groove of four supports is in the support roof intersection and communicate.Three very big and ganoid spherulas of hardness are arranged in each groove, come to 12 spherulas.They are evenly distributed in first sphere of big spheroid, and the adjacent two spherula centre ofs sphere are 25 degree with the angle of big spheroid centre of sphere line.Spherular effect is that support and big spheroid are separated, and reaches the purpose that turns to.The inner wall smooth of groove, and be circular arc, just in time spherula being embedded in wherein, depth of groove should be less than spherular radius.Separate with cage ring between the spherula, the shared cage ring of two relative sub-stents, each cage ring are that six bowl-shape annulus are formed by connecting, bowl-shape annulus just in time spherula is encased and intermediate space very little, two cage rings of cardan wheel are intersected and mistake.The effect of cage ring is evenly to separate spherula, prevents their phase mutual friction and collisions.The bottom of each sub-stent is close to big spheroid, and cage ring and sub-stent are linked together, and has fixed cage ring.
When cardan wheel turned to, big spheroid to any direction swinging mounting, made spherula rotate at big spherome surface as you were, realizes turning to.
The utility model has the advantages that:
Do not need to rotate big spheroid when 1, turning to, only need swinging mounting just can realize turning to.
2, friction force is very little between spheroid, rotates flexible.
3, simple in structure, be easy to make.
Description of drawings
Concrete structure of the present utility model is provided by the following drawings:
Accompanying drawing 1 is a birds-eye view of the present utility model
Accompanying drawing 2 is front views of the present utility model

The specific embodiment
Provide embodiment of the present utility model below in conjunction with accompanying drawing: when cardan wheel turned to, big spheroid [2] to any direction swinging mounting [1], made spherula [3] rotate on big spheroid [2] surface as you were, realizes turning to.
Claims (3)
1, a kind of cardan wheel, a big spheroid [2] is arranged in the middle of this cardan wheel, be a support [1] in the above, the top that it is characterized in that support [1] is a screwed connection handle, four sub-stents are arranged at the bottom, a groove [4] are arranged below each sub-stent, are evenly distributed with three spherulas [3] in each groove [4], spherula [3] separates support [1] and big spheroid [2], and separates with cage ring [5] between each spherula [3].
2, cardan wheel according to claim 1 is characterized in that support [1] has 3～8 sub-stents, has 1～5 spherula [3] under each sub-stent.
3, cardan wheel according to claim 1 is characterized in that cardan wheel made by steel, alloy or plastics.
