Abstract
The invention discloses a universal joint which comprises an external sleeve, a universal connecting rod and a joint, wherein a flange is arranged at one end of the external sleeve; an internal thread hole is formed at the other end of the external sleeve; an O-shaped ring is sleeved on the inner wall of the external sleeve; a spherical head is arranged at one end of the universal connecting rod; a combining section with an external thread is arranged at one end of the joint, corresponding to the internal thread hole of the external sleeve; an external thread combining end is arranged at the other end of the joint; the universal rod penetrates through the external sleeve to ensure that the head is clamped and blocked on the flange to further form point contact; the O-shaped ring is abutted against the head; and a thread section except the joint is screwed on the external sleeve. The universal joint disclosed by the invention is flexible and smooth to adjusting in position and is convenient to process and manufacture.
Description
Technical field
The present invention relates to a kind of structure improvement of universal joint, belong to the technical field of mechanical assembly.
Background technique
The universal joint of prior art comprises a spherical joint and a lock firmware, and by the external thread section of lock firmware and connecting tube lock knot, and the joint that this universal joint is spherical is mounted in the containing space of spherical concave surface of connecting tube.But universal joint will tend to cause universal joint to turn to when regulating because excessive frictional force is interfered and be hindered in the surperficial large size contact of joint, makes and regulates the inconvenience that action is dumb and use.
Therefore, for avoiding above-mentioned technical problem, the necessary rational more gimbal structure of a kind of project organization that provides is to overcome described defective of the prior art.
Summary of the invention
Technical problem at above-mentioned existence the objective of the invention is: proposed a kind of can light smooth and easy adjusting and make things convenient for the universal joint of manufacturing.
Technical solution of the present invention is achieved in that a kind of universal joint, and it comprises: external cover, universal extension bar and joint, and described external cover one end is provided with a flange, and the other end is provided with interior threaded hole, and its inner wall sleeve is provided with an O type ring; Universal extension bar one end has a ball head; The interior threaded hole of the corresponding external cover of one end of joint is provided with one and has externally threaded adapter section, and end is an outside thread binding end in addition; Described universal extension bar passes external cover makes the head jam on flange and form the some contact, and O type ring is connected on the head, and joint puts external with external thread section spiral shell knot.
Compared with prior art, the present invention has following beneficial effect: external cover inward flange of the present invention forms point with the joint adapter section and contacts, thereby has reduced the frictional force and the interfering edge of area of contact, and universal extension bar can smooth and easyly be swung, and regulates accessible.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Fig. 1 is the three-dimensional exploded view of universal joint of the present invention.
Embodiment
By the given embodiment of above-mentioned accompanying drawing, below be specifically described again.
See also shown in Figure 1ly, the present invention is a kind of universal joint, and it comprises external cover 10, one a universal extension bar 20 and a joint 30.Wherein, described external cover 10 covers one end is convexly equipped with an inward flange 11, and the other end is provided with interior threaded hole 12, and further, external cover 10 has an annular groove 13 and an O type ring 14 is installed in this annular groove 13 at inwall.Described universal extension bar 20 1 end tool ball head 21.The interior threaded hole 12 of the corresponding external cover of described joint 30 1 ends is provided with one and has externally threaded adapter section 31, and end is an outside thread binding end 32 in addition.
Combination relation of the present invention is as follows: described universal extension bar 20 passes external cover 10, makes ball head 21 heads 21 jams on flange 11; Again joint 30 is tied on the external cover 10 with external thread section 31 spiral shells, make the 21 spacing combinations of universal extension bar 20 ball head, and the binding end 32 of joint 30 is connected with the pipe joint that has outer inner bolt hole (not shown).
External cover inward flange 11 of the present invention forms point with joint 30 adapter sections 31 and contacts, thereby has reduced the frictional force and the interfering edge of area of contact, and universal extension bar 20 can smooth and easyly be swung, and regulates accessible.
The foregoing description only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
