Specific embodiment
Below against attached drawing, by the description of the embodiment, making to a specific embodiment of the invention further details of
Explanation.
This engine oil drainage structure of the present invention connects oil outlet fitting as shown in Figure 1, 2, 3 below oil sump, drains the oil
Connector includes the joint shell 2 being connected on oil sump, is equipped with oil pipe connecting tube 1 in joint shell 2, oil pipe connecting tube 1 can edge
Axially opposing joint shell 2 is mobile, and one end of oil pipe connecting tube 2 is to protrude into the inner end inside oil sump, and the other end is connection
The oil connection end 11 of oil pipe, inner end side be equipped with can move with it stretching or hide draining the oil to joint shell 2
Hole 14.In use, oil pipe is connected to oil connection end 11, oil pipe connecting tube 1 described in inside side pressure, oil pipe connecting tube 1 it is interior
Side, which moves inward, leaks out drain oil 14, and the oil in oil sump can be discharged by drain oil 14 through oil pipe connecting tube 1 and oil pipe, nothing
It needs to dismantle, realizes and exhaust gas machine oil is conveniently discharged.
In the present invention, as shown in fig. 1, return spring 3 is equipped between oil pipe connecting tube 1 and joint shell 2.Return spring
3 effect guarantees when unclamping hand, oil pipe connecting tube 1 can under the action of return spring 3 self-return, it is more convenient to use fast
It is prompt.
In the present invention, as shown in fig. 1, the lateral wall of oil pipe connecting tube 1 is equipped with spring protective case 12, and return spring 3
Support is placed in the cavity of spring protective case 12.2 outboard end of joint shell is equipped with the supporting table of support return spring 3, return spring 3
It is placed in spring protective case, one end is opposite with the end face of spring protective case, and the other end is supported in supporting table.Such structure setting peace
Entirely, beautiful and easy to use.In use, installation oil pipe is to oil connection end 11, while pressure oil pipe connected pipe 1 inwardly, oil pipe
The inner end of connecting tube 1, which moves inward, leaks out drain oil 14, and the oil in oil sump can be by drain oil 14 through 1 He of oil pipe connecting tube
Oil pipe discharge, as shown in figure 3, i.e. engine oil drainage structure open state;When draining the oil, 1 stress of oil pipe connecting tube moves inward,
Return spring 3 compresses, and generates elastic force, and when outside pressure is cancelled, oil pipe connecting tube 1 acts on next time in the elastic force of return spring 3
Position is to initial position, as shown in Figure 2, engine oil drainage structure closed state.
In the present invention, supporting table is equipped with the first sealing ring 4 being placed between joint shell 2 and spring protective case 12.Oil pipe
The inner end of connecting tube 1 is equipped with flange end cap 12, and flange end cap 12 is equipped with the second sealing ring 6.First sealing ring 4 and second is close
The case where seal 6 forms good sealing effect, prevents oil outlet fitting oil leak permeability.
In the present invention, 12 inner wall of spring protective case is equipped with limitation oil pipe connecting tube 1 and 2 displaced posi of joint shell
Limit circlip 5.When operation, the present embodiment engine oil drainage structure is pressed into spring protective case 12 inwardly and connects with construction section 23
Touching, this shift position guarantees that drain oil 14 leaks out, to realize oil extraction;When return, limit circlip 5 contacts clamping with supporting table and realizes
Complete return.
In the present invention, joint shell 2 includes the linkage section 22 being connected on oil sump, is inserting section on the inside of linkage section 22
21, the second sealing ring 6 is placed between 21 end of flange end cap 13 and inserting section, to guarantee good sealing effect.Linkage section 22
