Abstract

A kind of urea case lid with airing function, including screwing inner casing and the shell that is set on inner casing in urea box mouth, it further include the capsul being installed on inner casing, vent valve is equipped in capsul, and vent valve is abutted with inner casing, exhaust passage is formed between vent valve and inner casing, gas transmissive vent valve is simultaneously discharged by exhaust passage or is discharged urea box.This urea case lid can keep the pressure difference inside and outside urea box, prevent urea case lid because gas expansion deforms, and lead to not using improving service life, and still keep the sealing effect of liquid.Good airproof performance has anti-theft function, securely and reliably, can close locking closure, water proof anti-soil with automatic cover.

Description

A kind of urea case lid with airing function

Technical field

The utility model relates to a kind of urea case lid, especially a kind of urea case lid with airing function.

Background technique

Automobile urea box lid generally has higher leakproofness, and existing automobile urea box lid is substantially hermetically sealed, including gas Body and liquid.But if gas, which can not excessively be discharged, will lead to urea case lid dilatancy, to damage.

In order to overcome the above-mentioned deficiency of the prior art, the utility model provides a kind of urea case lid with airing function, It is not only simple in structure, it is easy to use, and can breathe freely, but still keep liquid and be not through urea case lid.

The technical scheme in the invention for solving the technical problem is: a kind of urea case lid with airing function, including The inner casing in urea box mouth and the shell being set on the inner casing are screwed, further includes the capsul being installed on the inner casing, Vent valve is equipped in the capsul, and the vent valve is abutted with inner casing, the row of being formed between vent valve and inner casing Gas channel, gas transmissive vent valve are simultaneously discharged into or are discharged urea box by the exhaust passage.

Preferably, being equipped with the first sealing ring being adapted to the vent valve between the capsul and vent valve.

Be equipped with preferably, be formed with accommodating chamber between the capsul and inner casing, in the accommodating chamber with it is described Compatible second sealing ring of capsul.

Preferably, the capsul bottom is equipped with limit card slot, the vent valve is caught in the limit card slot It is interior.

Preferably, being equipped with lock body between the inner casing and shell, the head of the lock body is equipped with lock core, the lock Core is threaded through the cover top portion, and the inner casing is equipped with ratchet, and the lower end of the lock body is threaded through in the ratchet.

Preferably, the shell is equipped with locking closure, and the locking closure is pivotally connected by shaft and the shell, institute The shaft stated is equipped with reduction torsion spring.

Preferably, the locking closure is equipped with annular protrusion, it is formed with annular groove between the lock core and shell, institute The annular protrusion stated can buckle into the annular groove.

Preferably, being additionally provided with circular pit on the shell, the circular pit is equipped with the lasso for preventing from falling.

The utility model has the beneficial effects that: being equipped with vent valve, allows gas through in it, keep in urea box Outer stabilization pressure difference, prevents urea case lid from deforming because of gas expansion, leads to not using and still keeping the close of liquid Seal effect.Limit card slot, which is arranged, fixes vent valve well, prevents that vent valve and itself and part is caused to collide because of rotation And cause to damage.Locking closure on shell can prevent impurity dust from entering in urea case lid, improve service life, and also set There is torsional spring, locking closure is closed on the shell automatically, prevents after use still in opening state.The setting of lasso so that Urea case lid prevents from losing after opening.

Detailed description of the invention

Fig. 1 is the explosive view of the utility model.

Fig. 2 is the top view of the utility model.

Fig. 3 is the semi-cutaway of the utility model.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and detailed description.

Referring to Fig.1~Fig. 3, a kind of urea case lid with airing function, including screwing inner casing 1 and set in urea box mouth The shell 2 being located on the inner casing 1, urea case lid further include the capsul 6 being installed on the inner casing 2, the capsul 6 It is inside equipped with vent valve 7, and the vent valve 7 is abutted with inner casing 1, is formed with exhaust passage between vent valve 7 and inner casing 1, Gas in urea box mouth can be drained into air by the exhaust passage.

In the present embodiment, it is close that first be adapted to the vent valve 7 is equipped between the capsul 6 and vent valve 7 Seal 8.

In the present embodiment, accommodating chamber 17 is formed between the capsul 6 and inner casing 1, in the accommodating chamber 17 Equipped with second sealing ring 9 compatible with the capsul 6.The setting of sealing ring well ensures the air-tightness of device.

In the present embodiment, 6 bottom of capsul is equipped with limit card slot 18, and the vent valve 7 is caught in described In limit card slot 18.Setting limit card slot 18 fixes vent valve 7 well, prevents from leading to vent valve 7 and its because of rotation It is collided with part and causes to damage.

In the present embodiment, lock body 3 is equipped between the inner casing 1 and shell 2, the head of the lock body 3 is equipped with lock core 4, the lock core 4 is threaded through 2 top of shell, and the inner casing 1 is equipped with ratchet 5, and the lower end of the lock body 3 is worn In the ratchet 5, the lower end of the lock body 3 is equipped with lock tongue, and when key opens lock, lock tongue is engaged on ratchet 5, shell 2 Linkage can be realized with inner casing 1, and when shell 2 is excessively tightened, because the radian of ratchet 5 designs, so that lock tongue skids off ratchet 5, and Issue the sound of click click.When key-off is locked, in lock tongue retraction lock body, shell 2 dallies, and realizes that urea case lid can not be opened.

In the present embodiment, the shell 2 is equipped with locking closure 10, and the locking closure 10 passes through shaft 11 and described Shell 2 is pivotally connected, and the shaft 11 is equipped with reduction torsion spring 12.Equipped with torsional spring, locking closure is closed on the shell automatically, It prevents after use still in opening state.

In the present embodiment, the locking closure is equipped with annular protrusion 13, is formed between the lock core 4 and shell 2 Annular groove 14, the annular protrusion 13 can buckle into 14 in the annular groove.The cooperation of annular protrusion 13 and annular groove 14 is set It sets, it is even closer, it being capable of more effectively dust-proof anti-impurity.

In the present embodiment, circular pit 15 is additionally provided on the shell 2, the circular pit 15 is equipped with and prevents The lasso 16 fallen.Lasso can prevent from falling in use, more convenient to use.

Utility model has the advantages that gas can be made through urea case lid, the pressure difference inside and outside urea box is kept, is prevented Urea case lid because gas expansion deform, and lead to not using, improve service life, and still keep liquid sealing effect Fruit,.Good airproof performance has anti-theft function, securely and reliably, can close locking closure, water proof anti-soil with automatic cover.

The present embodiment is one of more preferred scheme of this patent, and any do not depart from is made within the scope of the technical program Change, in the scope of this patent.
