Abstract

The utility model discloses a pipeline right-angle connector, which comprises a joint body (10). The joint body (10) is a connecting tube in a right-angle shape and made of metal material. The end portion of the joint body (10) is equipped with an external thread (20) and the root part of the external thread (20) is equipped with a sealing groove (30). A sealing ring (40) is sleeved inside the sealing groove (30). The root part of the external thread (20) is also equipped with a locking nut (50). The pipeline right-angle joint has the advantages of convenient connection and high sealing performance.

Description

The pipeline angle coupling
Technical field
The utility model relates to fork truck oil circuit pipeline interconnection technique, especially relates to a kind of pipeline angle coupling.
Background technique
Receive structural limitations owing to be used for the fork truck of engineering; Various oil circuit pipes connect frequent; Connecting pipeline bears that pressure is big, the seal degree requirement high, complex-shaped, and all there is the corner link position in a lot of pipeline, this link position is because angle is rectangular; Couple together inconvenience, and the oil pressure that bears is very high.Generally all adopt plastic tube to connect at the corner link position at present, because the easy bending of plastic tube, the connection that therefore is applied to the pipeline corner is very convenient.But because the restriction of the material behavior of plastic tube own is held and can't stand too high pressure, can cause the connecting tube wearing and tearing to produce hydraulic oil after long-time the use and ooze dew, influence the sealing of pipeline; Plastic tube end and fork truck pipeline connection are not easy sealing in addition, ooze the dew phenomenon through regular meeting.
The model utility content
To the deficiency that above-mentioned existing technology exists, the purpose of the utility model provides a kind of pipeline angle coupling, and it has easy to connect, the advantage that sealing is high.
To achieve these goals; The technological scheme that the utility model adopted is: the pipeline angle coupling, comprise joint body, and said joint body is the connecting tube of the rectangular shaped processed by metallic material; And the end of said joint body has outside thread; Said externally threaded root offers seal groove, is arranged with seal ring in the said seal groove, and said externally threaded root also is arranged with locking nut.
Preferably, be provided with packing ring between said seal ring and the said locking nut, and said packing ring size is greater than said seal ring and locking nut size.
Preferably, the coaxality of said outside thread and said seal groove is less than 0.05 millimeter.
Preferably, the gap between said seal ring and the seal groove is not more than 0.10 millimeter.
After adopting said structure; The utility model is compared the advantage that is had with existing technology: because the pipeline angle coupling itself has angle;, the pipeline corner can directly connect when being connected; Equally can operate very easily as plastic union pipe, therefore the utlity model has advantage easy to connect; In addition, the utility model directly is connected through screw thread and pipeline, and the untight shortcoming that has caused when having avoided plastic tube to connect has improved sealing, can not produce the phenomenon that hydraulic oil oozes dew, so the utility model also has the advantage of good airproof performance.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
Among the figure: 10, joint body; 20, outside thread;
30, seal groove; 40, seal ring;
50, locking nut; 60, packing ring.
Embodiment
The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model.
Embodiment, see shown in Figure 1:
The utility model is a kind of pipeline angle coupling; Comprise joint body 10; Said joint body 10 is connecting tubes of the rectangular shaped processed by metallic material, and the end of said joint body 10 has outside thread 20, and the root of said outside thread 20 offers seal groove 30; Be arranged with seal ring 40 in the said seal groove 30, the root of said outside thread 20 also is arranged with locking nut 50.The pipeline angle coupling of the utility model itself has angle, when the pipeline corner is connected, can directly connect, and can operate very easily with plastic union pipe is the same, therefore the utlity model has advantage easy to connect; In addition, the utility model directly is connected through screw thread and pipeline, and the untight shortcoming that has caused when having avoided plastic tube to connect has improved sealing, can not produce the phenomenon that hydraulic oil oozes dew, so the utility model also has the advantage of good airproof performance.
For the utility model is connected closely, better tightness is provided with packing ring 60 between said seal ring 40 and said locking nut 50; And said packing ring 60 sizes are greater than said seal ring 40 and locking nut 50 sizes, like this after locking nut 50 lockings, and locking nut 50 packing washers 60; Packing ring 60 compresses seal ring 40; Make seal ring 40 be close to the pipeline joint fully, stop that hydraulic oil oozes dew, it is better to make pipeline connect sealing.In addition; Better tightness when pipeline is connected; The coaxality of said outside thread 20 and said seal groove 30 is less than 0.05 millimeter; And the gap between said seal ring 40 and the seal groove 30 is not more than 0.10 millimeter, connects each pipe of back at pipeline like this and has alignment preferably, can improve sealing.
The pipeline angle coupling of the utility model not only has easy to connectly, also has the high advantage of sealing.
