Embodiment Construction

[0043] A first embodiment of the universal joint of the present invention will be described below with reference to FIGS. 1 to 3 .

[0044] Referring to Fig. 1, the universal joint 20 includes an intermediate tubular member 21, a first tubular member or plug member 22 connected with the intermediate tubular member 21, a second tubular member or sleeve member connected with the intermediate tubular member 21 twenty three. By connecting the intermediate tubular, plug and sleeve members, a conduit is formed through which fluid passes. The intermediate tubular, plug and sleeve members are made of steel or plastic resin or the like.

[0045] As shown in FIG. 2( a ), the intermediate tubular member 21 has an outer spherical portion 24 at one end and a cylindrical portion 25 at the other end. The outer spherical portion 24 is formed by spherically forming the outer peripheral surface 21a of the intermediate tubular member. The outer peripheral surface 21 a of the intermediate tubu...

Abstract

The invention discloses a universal joint, which comprises a first pipe-shaped component, a second pipe-shaped component and a middle pipe-shaped component which is used to connect the first and the second pipe-shaped components. The first pipe-shaped component and the middle pipe-shaped component are connected to do universal motion relative to each other. And the middle pipe-shaped component and the second pipe-shaped component are connected to do rotatable motion relative to each other.

Description

[0001] This application is a divisional application with the applicant Dasen Co., Ltd., the application number 03106066.8, the application date being February 20, 2003, and the title "universal joint". technical field [0002] The invention relates to a universal joint for connecting two tubular members through which a fluid passes. Background technique [0003] Fig. 7 shows a first type of conventional universal joint. The universal joint 200 includes: a plug member 201, one end of which is connected to a bracket or socket (not shown); an intermediate tubular member 203, one end of which is rotatably connected with the plug member 201 through a ball bearing 204; and a A sleeve member 202, which is connected at one end to the other end of the intermediate member through a ball bearing 205, and is connected to a tool such as an air tool (not shown) at the other end. [0004] The axis G1 of one end of the intermediate tubular member 203 is inclined at an angle to the axes G2 ...
