Description

Oil tank port cover drainage structure

Technical Field

The utility model belongs to the technical field of the oil tank, a fuel tank port lid drainage structures is related to.

Background

The motorcycle oil tank is the important part of motorcycle, installs at the rear of motorcycle locomotive, current motorcycle is in order to refuel in convenience, the oil filler hole generally all sets up on the oil tank top surface, be equipped with on the oil tank owing to the heavy groove of installation fuel tank cap, all can cause the heavy inslot to produce ponding when riding in the rainy day or unexpected trickle, ponding just persists and is difficult for flowing in the heavy groove, if not get rid of in time, the aqueous vapor not only can pollute the oil tank, and influence the use of motorcycle, need often clean.

In view of the above problems, various tank cap drainage structures have been developed:

if chinese patent application (application publication No. CN 104276236A) discloses a waterproof oil tank, including the oil tank body, be equipped with the heavy groove that is used for installing the oil tank lid on the oil tank body, the bottom surface of heavy groove is equipped with oil inlet and water leakage mouth, and the bottom surface of heavy groove corresponds the water leakage mouth and is equipped with the water drainage tank, and the water drainage tank is the gradual change groove of the increase gradually of the degree of depth of water leakage mouth from both ends.

Although above-mentioned structure is provided with the mouth of a river and the water drainage tank in the bottom surface of sinking the groove and realizes the ponding discharge that will sink the inslot, ponding in the heavy groove is through setting up from both ends to the water drainage tank direction of leaking the mouth of a river degree of depth crescent to leaking the mouth of a river, because the bottom surface of sinking the groove is great, make only to rely on the water drainage tank to lead ponding to leaking the mouth of a river, and the water drainage tank is only the half moon groove that sets up at heavy groove bottom surface edge, make the water drainage tank only can lead to leaking in the ponding part of sinking the groove, it has remained to have leaded to most ponding of sinking the inslot, thereby the drainage effect of oil tank body has been reduced.

Disclosure of Invention

The utility model aims at having the above-mentioned problem to current technique, provided a fuel tank port lid drainage structures, the utility model aims to solve the technical problem that: how to solve the relatively poor problem of drainage effect of current oil tank flap.

The purpose of the utility model can be realized by the following technical proposal:

the utility model provides an oil tank port lid drainage structures, oil tank port lid include the lid base and offer the oil tank port on the lid base, have in the lid base around the annular groove that gathers that is that oil tank port sets up, its characterized in that, this drainage structures include the drain pipe and set up on the lid base be the annular groove that assembles, it is located the inboard that gathers the groove to assemble the groove, the tank bottom that gathers the groove is higher than the tank bottom that assembles the groove, the lid base has above-mentioned drain pipe in the outside that gathers the groove, the outer end of drain pipe is outwards, the inner of drain pipe with assemble the groove intercommunication.

The working principle is as follows: when the bicycle is ridden in rainy days or drenches water accidentally, water can enter the cover base through the oil tank cover, the cover base is internally provided with the annular flow gathering groove, the water flowing into the cover base is positioned in the flow gathering groove, the cover base is provided with the gathering groove on the inner side of the flow gathering groove, the groove bottom of the gathering groove is lower than the flow gathering groove, so the water flowing into the flow gathering groove can flow into the gathering groove, the water can be drained out of the cover base through the gathering groove by arranging the drain pipe on the outer side of the cover base, the water in the flow gathering groove can be quickly gathered through the gathering groove, and the gathering groove and the flow gathering groove are annular and are positioned on the inner side of the flow gathering groove, so that the water in the flow gathering groove can all flow into the gathering groove and then be drained out of the cover base through the drain pipe, thereby realizing the drainage of the oil tank cover, thereby can further promote the drainage effect of oil tank port lid drainage structures.

In the above-mentioned oil tank flap drainage structure, the drain pipe is connected with the lateral wall of lid base, and the water inlet of drain pipe is located the inside wall of lid base.

The setting of this structure has made things convenient for the discharge of water liquid in the drain pipe to be located the inside wall of apron base with the water inlet of drain pipe, make the production and processing convenience more of drain pipe, and also can be stable ponding discharge in the apron base, promoted the stability of oil tank port lid drainage structure drainage.

In foretell oil tank flap drainage structures, the tank bottom of gathering groove is sunken to form water drainage tank, water drainage tank will gather groove and drain pipe intercommunication.

Through the setting of water drainage tank for gather ponding in the inslot and discharge from the drain pipe that can be faster, and gather ponding on the chute and also can directly flow into in the drain pipe from water drainage tank, further promotion the drainage effect of oil tank port lid drainage structure.

In foretell oil tank flap drainage structures, the water drainage tank has the barrier wall just to setting up with the water inlet of drain pipe, the water drainage tank have with assemble the breach of groove intercommunication, and the breach is located one side of barrier wall.

The setting of this structure has avoided external water to enter into from the drain pipe and has assembled the inslot to when the rainwater is more, can play certain cushioning effect, avoided flowing into the ponding velocity of flow in the drain pipe too fast, promoted the stability of drainage.

In the above oil tank port cover drainage structure, the bottom of the collecting groove and the bottom of the collecting groove are in arc transition.

The setting of this structure can lead to gathering ponding on the chute for ponding can be faster flow in to assemble the inslot, further promotion oil tank port lid drainage structures's drainage effect.

Compared with the prior art, this fuel tank port lid drainage structures has the advantage: because assemble the groove and gather the chute and all be the annular, assemble the trench in gathering the chute inboard, can make the hydroenergy in gathering the chute all flow into and assemble the inslot, the rethread drain pipe discharge lid base to realized the drainage to the oil tank port lid, thereby can further promote the drainage effect of oil tank port lid drainage structures.
