As preferably, the inner circle wall of described packing ring and the outer wall drive fit of screw rod.
As preferably, described oil pipe body comprises pipe in an outer tube and, and outer tube is made up of glass fibre, and interior pipe is made up of teflon.
After adopting above structure, the utility model compared with prior art, has following advantage:
1, because packing ring is between adjacent two thread ridges of screw rod and by these two thread ridges axial limitings, and the external diameter of packing ring is greater than the diameter of through hole, like this, packing ring is laid on the end face of oil connection, cross oil draining bolt then spacing by packing ring institute by the thread ridges on screw rod, made oil draining bolt can not from landing the through hole of oil connection, doing so avoids crossing the situation of oil draining bolt from landing oil connection by crossing when oil draining bolt is connected with engine oil inlet mouth, facilitating the connection of oil draining bolt.
2, the inner circle wall of packing ring and the outer wall drive fit of screw rod, like this, makes packing ring and crosses between oil draining bolt radial spacing, make packing ring and cross fixation between oil draining bolt, made oil draining bolt fixing firm.
3, the outer tube be made up of glass fibre is high temperature resistant, wear-resisting, bending radius is less, and fatigue resistance is better, and can reduce noise, and in being made up of teflon, pipe has excellent corrosion resistance.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Shown in Fig. 1 ~ Fig. 3, the utility model engine oil tube assembly comprises an oil pipe body 1, one end of oil pipe body 1 is provided with an oil connection 2 and and crosses oil draining bolt 3, oil connection 2 is provided with a through hole 201, the both ends of the surface of the through oil connection 2 of through hole 201, oil pipe body 2 is communicated with through hole 201, the screw rod 301 crossing oil draining bolt 3 is located in through hole 201, the head 302 crossing oil draining bolt 3 is positioned at one end of oil connection 2, the screw rod 301 crossing oil draining bolt 3 stretches out in the other end of oil connection 2, the screw rod 301 crossing oil draining bolt 3 is provided with one and crosses oily passage 3011, the sidewall that the one end crossing oily passage 3011 is positioned at screw rod 301 is positioned at through hole 201, the other end crossing oily passage 3011 is positioned on the end face away from head 302 of screw rod 301, serve as after oil draining bolt 301 is connected with engine oil inlet mouth, oil in oil pipe body 1 passed through oily passage 3011 inflow engine, the part stretching out in the other end of oil connection 2 of described screw rod 301 is equipped with a packing ring 4, described packing ring 4 is between adjacent two thread ridges 303 of screw rod 301 and by these two thread ridges 303 axial limitings, the external diameter of packing ring 4 is greater than the diameter of through hole 201, like this, as shown in Figure 3, serve as oil draining bolt 3 when falling, packing ring 4 is by the end face backstop of oil connection 2, like this, cross oil draining bolt 3 by the thread ridges 303 on screw rod 301 by packing ring 4 backstop, made oil draining bolt 3 cannot from landing in the through hole 201 of oil connection 2.
The inner circle wall of described packing ring 4 and the outer wall drive fit of screw rod 301.
Described oil pipe body 1 comprises pipe 102 in an outer tube 101 and, and outer tube 101 is made up of glass fibre, and interior pipe 102 is made up of teflon.
The manufacture method of above-mentioned engine oil tube assembly, comprises the following steps:
(1), machining packing ring, packing ring is made up of metallic material, the packing ring machined comprises the first annulus 401 and the second annulus 402, first annulus 401 and the second annulus 402 all radially extend, spacing is left and both overlap in the axial direction between first annulus 401 and the second annulus 402, the inner peripheral surface of the first annulus 401 is connected by loop connecting portion 403 with the inner peripheral surface of the second annulus 402, loop connecting portion 403 axial direction extends, and now the internal diameter of packing ring 3 was greater than the diameter of the screw rod 301 of oil draining bolt 3.
