Therefore, how to improve the structure of oil pipe assembly, connect sealing, become the technical barrier that those skilled in the art needs to be resolved hurrily to optimize it.
The model utility content
The purpose of the utility model provides a kind of oil pipe assembly, and the connection sealing of this oil pipe assembly is better.Another purpose of the utility model provides a kind of motor with above-mentioned oil pipe assembly.
In order to realize above-mentioned first purpose, the utility model provides following technological scheme:
A kind of oil pipe assembly comprises oil pipe and pipe joint, also comprises inipple, and said inipple one end and said oil pipe constitute integral structure, and the other end is threaded with said pipe joint.
Preferably, to be positioned at said pipe joint outside for the end that is connected with said pipe joint of said inipple.
Preferably, said pipe joint is connected with said inipple through auxiliary joint, and said auxiliary joint and said pipe joint removably are tightly connected.
Preferably, said auxiliary joint is threaded with said pipe joint.
In technique scheme, the oil pipe assembly that the utility model provides comprises oil pipe, pipe joint and inipple, and inipple one end and oil pipe constitute integral structure, and the other end is threaded with pipe joint.During installation, only need inipple is connected with pipe joint and promptly accomplished being connected of this oil pipe assembly and motor, mobile between different institutions of realization fluid.
Can know that through foregoing description oil pipe assembly that the utility model provides adopts inipple, oil pipe is improved to by socket with the Placement of pipe joint is threaded, and oil pipe and inipple are integral structure.Obviously; With respect to socket; The join strength that is threaded is higher, connect better tightness, and the vibration of motor weakens with the influence that is produced that is connected between the pipe joint oil pipe to some extent, thereby has reduced the probability that oil leakage phenomenon takes place; Avoid the waste of fluid, and reduce engine operation safety of environment hidden danger.
In order to realize above-mentioned second purpose, the utility model also provides a kind of motor, and this motor comprises cylinder body and the oil pipe assembly that is connected with said cylinder body, and said oil pipe assembly is above-mentioned each described oil pipe assembly.Because above-mentioned oil pipe assembly has above-mentioned technique effect, the motor with this oil pipe assembly also should have the corresponding techniques effect.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiments of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
The structural representation of the inipple that Fig. 1 provides for the utility model specific embodiment;
The structural representation of the auxiliary joint that Fig. 2 provides for the utility model specific embodiment;
Fig. 3 is the sectional structure schematic representation of Fig. 2.
Embodiment
The core of the utility model provides a kind of oil pipe assembly, and the connection sealing of this oil pipe assembly is better.Another core of the utility model provides a kind of motor with above-mentioned oil pipe assembly.
In order to make those skilled in the art understand the technological scheme of the utility model better, will combine accompanying drawing and specific embodiment that the utility model is done further to specify below.
Referring to Fig. 1 and Fig. 2, the structural representation of the auxiliary joint that the structural representation of the inipple that Fig. 1 provides for the utility model specific embodiment, Fig. 2 provide for the utility model specific embodiment.
As depicted in figs. 1 and 2, in a kind of specific embodiment, the oil pipe assembly that the utility model provides comprises oil pipe 11, pipe joint 14 and inipple 12, and an end of inipple 12 and oil pipe 11 constitute integral structure, and the other end is threaded with pipe joint 14.Inipple 12 specifically can be with the thread connecting mode of pipe joint 14: on inipple 12, outside thread is set, and in pipe joint 14 ends the internal thread that cooperates with above-mentioned outside thread is set.During installation, only need inipple 12 is connected with pipe joint 14 and promptly accomplished being connected of this oil pipe assembly and motor, mobile between different institutions of realization fluid.
Can know that through foregoing description oil pipe assembly that the utility model provides adopts inipple 12, oil pipe 11 is improved to by socket with the Placement of pipe joint 14 is threaded, and oil pipe 11 and inipple 12 are integral structure.Obviously; With respect to socket; The join strength that is threaded is higher, connect better tightness, and the vibration of motor decreases and weakens the influence that is produced that is connected between oil pipe 11 and the pipe joint 14, thereby reduced the probability of oil leakage phenomenon generation; Avoid the waste of fluid, and reduce engine operation safety of environment hidden danger.
Further in the technological scheme; An end that is connected with pipe joint 14 on the inipple 12 is positioned at pipe joint 14 outsides; Promptly; Inipple 12 is provided with internal thread, and pipe joint 14 is provided with the outside thread with above-mentioned screw-internal thread fit, realizes being threaded of inipple 12 and pipe joint 14 with this.In this scheme, oil pipe 11 and pipe joint 14 all are connected in the inboard of inipple 12, and the difference of both diameters can be not excessive, are unlikely to cause the flow velocity of fluid to produce bigger variation, thereby guarantee the flow stability of fluid.
Referring to Fig. 2 and Fig. 3, Fig. 3 is the sectional structure schematic representation of Fig. 2 simultaneously.
As shown in Figures 2 and 3, in the technological scheme further, pipe joint 14 is connected with inipple 12 through auxiliary joint 13, and auxiliary joint 13 removably is tightly connected to realize both with pipe joint 14 interference fit.In this scheme, auxiliary joint 13 is as the be connected medium of inipple 12 with pipe joint 14, and can avoiding on pipe joint 14 directly, machining screw causes accidental injury to pipe joint 14.Simultaneously, auxiliary joint 13 in use can be changed easily, thereby reduces the maintenance cost of this oil pipe assembly.
In the optimized technical scheme, above-mentioned auxiliary joint 13 and pipe joint 14 interference fit are also replaceable for both are threaded.This scheme makes that the installation and removal of auxiliary joint 13 are more convenient; And with respect to interference fit; The join strength that is threaded is higher; More difficult generation oil leakage phenomenon when fluid is flowed through connection part between auxiliary joint 13 and the pipe joint 14 is strengthened the functional reliability of this oil pipe assembly with this.
