Description
Technical field
The utility model is related to a kind of oil discharge screw.
Background technology
Oil discharge screw is the fit sealing part being connected with fuel tank oil outlet, the oil discharge screw used in some pressure-oil tanks
When draining the oil, come out once the both sides drain oil on oil discharge screw with meeting splash after fuel tank insertion, larger dirt is brought to environment
Dye, easily influences the job morale of workman, to avoid pollution problem of draining the oil, it is necessary to redesigns and changes oil discharge screw structure.
The content of the invention
To solve the above problems, the purpose of this utility model is that providing one kind can in one direction draw oil and can receive
The oil discharge screw of collection, so as to reduce pollution of draining the oil.
To achieve the above object, the utility model provides following technical scheme：A kind of oil discharge screw, including bolt head and
Annular groove is provided with close to the side of the bolt head on screw rod, described screw rod, is provided with described screw rod location mid-shaft
Intercommunicating pore, provided with the drain oil with the intercommunicating pore insertion in the diametric(al) of described annular groove, described is annular recessed
Groove is provided with the arc groove corresponding with the drain oil, and the bottom of described drain oil from described arc groove is passed,
Fairlead is provided with described drain oil, one end of the fairlead is the blind end in closed state, is drawn described
Pipe is provided with side port on the side face of blind end, and the blind end of fairlead is pressed into by the side port towards the intercommunicating pore on screw rod
When in the drain oil, the side port of the fairlead connects with the intercommunicating pore.
The length of described fairlead and the diameter of the annular groove match.
Described fairlead is copper material.
By using having the beneficial effect that above-mentioned technical proposal is reached：Oil discharge screw is screwed out from fuel tank oil outlet to putting
When oilhole is exposed, due to being provided with fairlead in drain oil, now the side port of fairlead is in contact with the hole wall of drain oil,
So that oil can't be drawn from fairlead, and when then the blind end of fairlead is pressed into drain oil, the side port of fairlead
Connected with intercommunicating pore so that oil draws to be socketed on fairlead by leather hose simultaneously from the opening of fairlead makes oil flow into oil drum
Interior to collect, so just realizing can draw oil and collectable technique effect in one direction, so as to reduce pollution of draining the oil.
The utility model is further described with reference to the accompanying drawings and detailed description.
Brief description of the drawings
Fig. 1 is the stereogram of the utility model embodiment；
Fig. 2 is the explosive view of the utility model embodiment；
State diagram when Fig. 3 is not pressed for the blind end of fairlead；
Fig. 4 is pressed into state diagram when in drain oil for the blind end of fairlead.
Embodiment
The utility model is specifically described below by embodiment, is served only for carrying out further the utility model
Explanation, it is impossible to be interpreted as the restriction to the utility model protection domain.
As shown in Figure 1 and Figure 2, the utility model discloses a kind of oil discharge screw, including bolt head 1 and screw rod 2, on screw rod 2
Annular groove 21 is provided with close to the side of bolt head 1, hole 22 is communicated with the location mid-shaft of screw rod 2, in annular groove 21
Diametric(al) is provided with the arc corresponding with drain oil 23 provided with the drain oil 23 with the insertion of intercommunicating pore 22, annular groove 21
Groove 3, the bottom of drain oil 23 from arc groove 3 is passed, and fairlead 4 is provided with drain oil 23, and one end of fairlead 4 is
In the blind end 41 of closed state, side port 42 is provided with the side face of blind end 41 in fairlead 4, the side port 42 is towards screw rod
Intercommunicating pore 22 on 2, as shown in figure 4, when the blind end 41 of fairlead 4 is pressed into drain oil 23, the side port 42 of fairlead 4
Connected with intercommunicating pore 22.
The length of fairlead 4 and the diameter of annular groove 21 match.It can so make structure more rationally reliable, but will draw
When the blind end 41 of outlet pipe 4 is pressed into drain oil 23, the side face of the extended annular groove 21 of opening of the other end of fairlead 4,
It is convenient to be connected by leather hose, while not interfering with overall structure in assembling.
Fairlead 4 is copper material.Because copper is difficult to get rusty, it can so extend the service life of fairlead.
In embodiment, oil discharge screw screwed out from fuel tank oil outlet to drain oil 23 be exposed when, as shown in figure 3, by
In being provided with fairlead 4 in drain oil 23, now the side port 42 of fairlead 4 is in contact with the hole wall of drain oil 23 so that oil is also
Can not be drawn from fairlead 4, when then the blind end 41 of fairlead 4 is pressed into drain oil 23, it is specific as shown in figure 4,
The side port 42 of fairlead 4 is connected with intercommunicating pore 22 so that oil draws to be socketed in by leather hose simultaneously from the opening of fairlead 4 to be drawn
Oil is set to flow into collection in oil drum in outlet pipe 4, so just realizing can draw oil and collectable technique effect in one direction,
So as to reduce pollution of draining the oil.
