Abstract
The invention discloses a bullseye universal wheel. The bullseye universal wheel comprises a column body. A pit is formed in the center of the right end surface of the column body, a steel ball is contained in the pit, an annular extension side clamping the steel ball to prevent the steel ball from being separated from the pit is arranged on the right end surface of the column body, and a small part of the steel ball is exposed. A teflon bowl-shaped body is arranged between the steel ball and the pit, the inner surface of the teflon bowl-shaped body is matched with the surface of the steel ball, and the outer surface of the teflon bowl-shaped body is matched with the inner surface of the pit. A screw rod used for being connected with a moving part is arranged in the center of the left end surface of the column body.
Description
Technical field
The present invention relates to a kind of buphthalmos cardan wheel.
Background technology
Need the moving article bottom of moved by hand that cardan wheel is usually installed, what installed some moving articles bottom is buphthalmos cardan wheel, but after the long-time use of some buphthalmos cardan wheels, its steel ball rotates can be dumb, while causing moving article to move, relatively requires great effort.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, a kind of buphthalmos cardan wheel is provided, its steel ball rotates more flexible.
The technical solution adopted for the present invention to solve the technical problems is: a kind of buphthalmos cardan wheel, comprise cylinder, cylinder right-hand member end face center offers pit, in pit, accommodate steel ball, cylinder right-hand member end face has the annular extension edge that blocks steel ball disengaging pit, steel ball fraction exposes, between steel ball and pit, be provided with polytetrafluoroethylene bowl-shaped body, polytetrafluoroethylene bowl-shaped body inside face and steel ball surface match, polytetrafluoroethylene bowl-shaped body outside face and pit inside face fit, and cylinder left end end face center has for connecting the screw rod of moving article.
The invention has the beneficial effects as follows: the present invention is provided with polytetrafluoroethylene bowl-shaped body between steel ball and pit, and due to polytetrafluoroethylene good weatherability, friction coefficient is low, thereby steel ball rotation can be very flexible.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the present invention is further described.
Fig. 1 is structural representation of the present invention.
In figure: 1. screw rod; 2. cylinder; 3. polytetrafluoroethylene bowl-shaped body; 4. annular extension edge; 5. steel ball.
The specific embodiment
The present invention is further illustrated by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
A kind of buphthalmos cardan wheel as shown in Figure 1, comprise cylinder 2, cylinder 2 right-hand member end face centers offer pit, in pit, accommodate steel ball 5, cylinder 2 right-hand member end faces have the annular extension edge 4 that blocks steel ball 5 disengaging pits, steel ball 5 fractions expose, between steel ball 5 and pit, be provided with polytetrafluoroethylene bowl-shaped body 3, polytetrafluoroethylene bowl-shaped body 3 inside faces and steel ball 5 surfaces match, polytetrafluoroethylene bowl-shaped body 3 outside faces and pit inside face fit, and cylinder 2 left end end face centers have for connecting the screw rod 1 of moving article.
Above-mentioned embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
