The invention discloses a quick coupling for connecting oil tubes of an oil filter. The quick coupling comprises an external thread tube head, a first extension tube, a sealing rubber mat, an internal thread tube head and a second extension tube, wherein one end of the internal thread tube head is connected with the second extension tube, the internal thread tube head can rotate independently relative to the second extension tube, a groove is formed in the end face of the other end of the internal thread tube head, the annular sealing rubber mat is placed in the groove, the external thread tube head is fixedly connected with the first extension tube, a boss is arranged at the joint of the external thread tube head and the first extension tube, and the first extension tube and the second extension tube are connected with the oil tubes respectively. According to the quick coupling for connecting the oil tubes of the oil filter, quick and convenient connection of the oil tubes can be achieved, it is guaranteed that the joint of the oil tubes is firm, not easy to damage and good in sealing, and thus oil filtering quality is improved.
Description
Technical field
The present invention relates to the jointing between oil pipe, the rapid pipe joint that particularly oil filter oil pipe connects.
Background technique
At oil filter, carry out in the process of oiling, need to be connected with various oil storage equipment frequently, and the connection of existing more piece oil pipe, the method of its use is to add a trifle diameter to be less than the connecting tube of oil pipe, insert respectively in two oil pipes that need to connect at two ends, use again iron wire colligation joint, these class methods are connection procedure more complicated not only, time used is longer, and oil pipe connection effect is poor, the poorly sealed easy seepage in joint, the fragile oil pipe of colligation, both affected working efficiency, dangerous again.
Summary of the invention
In order to overcome the not tight easily problem of seepage, the fragile oil pipe of colligation in oil filter oil pipe joint, the invention provides a kind of oil filter oil pipe and connect rapid pipe joint, realize oil pipe and connect quickly and easily, and guarantee to improve oil strain quality by firm not fragile, the good seal in oil pipe joint.
The present invention solves the problems of the technologies described above the technological scheme adopting to be:
A kind of oil filter oil pipe connects rapid pipe joint, comprise outside thread tube head, the first extension tube, seal rubber pad, internal thread tube head, the second extension tube, the first end of described riffled tube is connected with described the second extension tube, described internal thread tube head can independent rotation with respect to described the second extension tube, the end face of the other end of described internal thread tube head has a groove, the seal rubber pad of annular is placed in described groove, described outside thread tube head is fixedly connected with described the first extension tube, and there is a boss outside thread tube head and the first extension tube joint, the internal diameter of the seal rubber pad of annular is greater than the external diameter of outside thread tube head, and be less than the external diameter of the boss on outside thread tube head, described the first extension tube, the second extension tube is connected with oil pipe respectively.
Further, in the inner chamber matching with described internal thread tube head at described outside thread tube head, screen holder is set, on described screen holder, is fixedly installed a filter screen.
Further, some oil pipe draw-in grooves are set on the outer wall of described the first extension tube and described the second extension tube, described oil pipe draw-in groove interval arranges.
Further, material selection low carbon steel or the cast iron of described outside thread tube head, internal thread tube head.
The invention has the beneficial effects as follows, adopt independently rotary internal thread tube head, it is easy to operate when oil pipe connects, saved the operating time, corresponding seal rubber pad is set on sealing surface,, there is not leakage phenomenon in favorable sealing property while guaranteeing oiling, in the chamber that tube head connects simultaneously, filter screen is set, guarantees oil filter oil strain quality.
Accompanying drawing explanation
Fig. 1 is for being with externally threaded the first oil connection schematic diagram.
Fig. 2 is tapped the second oil connection schematic diagram.
In figure, each component names is as follows:
1-outside thread tube head, 2-the first extension tube, 3-seal rubber pad, 4-internal thread tube head, 5-the second extension tube
Embodiment
Below in conjunction with accompanying drawing, describe the present invention.
With reference to Fig. 1-2, oil filter oil pipe of the present invention connects rapid pipe joint, comprises outside thread tube head 1, the first extension tube 2, seal rubber pad 3, internal thread tube head 4, the second extension tube 5.Wherein internal thread tube head 4 one end are connected with the second extension tube 5, and internal thread tube head 4 can independent rotation with respect to the second extension tube 5, and the end face of the other end of internal thread tube head 4 groove that concaves into, to place annular seal rubber pad 3.Outside thread tube head 1 is fixedly connected with the first extension tube 2, and there is a boss outside thread tube head 1 and the first extension tube 2 joints, to can push the seal rubber pad 3 in internal thread tube head when outside thread tube head 1 is connected with internal thread tube head 4.The internal diameter of the seal rubber pad 3 of annular is greater than the external diameter of outside thread tube head 1, but is less than the external diameter of the boss on outside thread tube head 1.Outside thread tube head 1 can with internal thread tube head 4 screw-thread fit.Outside thread tube head 1 inserts the first extension tube 2 in oil pipe, and outside is fixed on oil pipe with special-purpose fastening metal circle, and internal thread tube head 4 inserts the second extension tube 5 in oil pipe simultaneously, and outside is also fixed on oil pipe with special-purpose fastening metal circle.
In the inner chamber matching with internal thread tube head 4 at male-pipe head 1, screen holder is set, on screen holder, is fixedly installed a filter screen (accompanying drawing is not shown), guarantee oil filter oil strain quality.
Oil pipe draw-in groove (accompanying drawing is not shown) is set on the outer wall of the first extension tube 2 and the second extension tube 5, and in order to guarantee being tightly connected of the first extension tube 2 and the second extension tube 5 and oil pipe, oil pipe draw-in groove can arrange several roads more, and oil pipe draw-in groove interval arranges.
Material selection low carbon steel or the cast iron of described outside thread tube head, internal thread tube head.Also can select the material that other are firm, wear-resisting, oil resistant corrodes.
When oil connection connects, internal thread tube head 1 is docked with outside thread tube head 4, rotation can independent rotation internal thread tube head 1, couple together with outside thread tube head 4, then with spanner, internal thread tube head 4 is tight dead, now, the seal rubber pad 3 in tube head is compacted, can be good at sealing oil pipe joint, under the high oil pressure that can produce in oiling, Seepage does not occur.Such attended operation is simple and convenient, in the time of can guaranteeing oiling, leakage phenomenon does not occur simultaneously, has saved the operating time, has improved Security.
Although above-mentioned, by reference to the accompanying drawings the specific embodiment of the present invention is described; but be not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technological scheme of the present invention, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection scope of the present invention.
