Description

Low-speed rotating joint

Technical Field

The utility model relates to the technical field of joints, in particular to a joint capable of rotating at a low speed.

Background

In telecommunications terminology, a joint is a device that is installed between cables, has certain insulating and sealing properties, and allows two or more cables to run continuously. In the genetic engineering technology, two DNA molecules or two ends of one DNA molecule can be matched by enzyme digestion and then are covalently linked by ligase. Synthetic hexamer linkers (containing a nick for a particular enzyme) are now commonly used, as are multiple hexamer linkers joined together to form a polylinker.

At present, a low-speed rotating joint is fixed and difficult to adjust between a part of common joints and connecting pipes, and when the low-speed rotating joint is overhauled or used, adverse effects are easily caused between the joints and the connecting pipes due to the fact that the connecting pipes are rotated, so that a novel low-speed rotating joint is provided at present.

Disclosure of Invention

Technical problem to be solved

In view of the deficiencies of the prior art, the present invention provides a low speed rotary joint that solves the problems set forth in the background above.

(II) technical scheme

In order to achieve the purpose, the utility model is realized by the following technical scheme: the utility model provides a rotatory joint of low-speed, includes the joint, the inside that connects is seted up flutedly, it has the connecting pipe to connect through recess swing joint, the tip of recess inner wall is seted up and is the inclined plane that the contained angle set up with the vertical horizontal line that connects, the surface of connecting pipe is equipped with the annular groove with inclined plane looks adaptation, the inside in annular groove is equipped with first O type circle, the logical groove of looks adaptation is all seted up with the surface of connecting pipe to the bottom portion of recess, the inside that leads to the groove is equipped with C type jump ring, nested second O type circle in the cavity that the bottom of recess and connecting pipe formed.

Preferably, the cross section of the first O-ring is elliptical.

Preferably, the end of the joint is provided with an external thread.

Preferably, the joint between the external thread of the joint and the end of the joint is inclined.

The utility model provides a low-speed rotating joint, which has the following beneficial effects:

this rotatory joint of low-speed compares with prior art, and the device is through the setting of first O type circle, C type jump ring and second O type circle for the joint can rotate, and rotates to certain degree back automatic re-setting, and through the setting of first O type circle and second O type circle, can increase the leakproofness of this structure, avoids producing adverse effect, thereby improves the device's practicality.
