The utility model provides a gas drive urea tank cover with a secret locking mechanism, including a key, a lock lock core, a latch, a urea tank, a filling pipe, a cover, an anti strip and a dustproof cover; the upper end of the injection pipe is fixed with the cover and the lower end is fixed with the urea tank; the key spoon is fitted with the lock core core. The latch is fixed at the lower end of the lock core, and the outer wall of the injection pipe is provided with a ring lock slot fitted with the latch; one end of the dustproof cover is articulated with the cover, and the other end of the dust cover is sealed with the lock core, and one end of the strip is fixed with the injection pipe, and the other end is connected with the other end. The dust cover is fixed. The cover of the utility model is not easy to loose and shedding, and the dust cover is added to the lock hole of the urea tank cover, and the strip is added to the dust cover to prevent the loss and loss of the urea tank cover when the cap is screwed down, so as to ensure the stable and normal work of the gas drive urea tank.

带注口暗锁机构的气驱尿素罐盖
本技术涉及气驱尿素罐盖
,尤其涉及一种带注口暗锁机构的气驱尿素罐盖。
技术介绍
通常的气驱尿素罐螺纹盖不防松、不带暗锁,由于汽车气驱尿素罐是压力容器,压力并不太稳定,容易造成盖松动,一旦松动或脱落,气驱尿素罐不密封就无法工作;而尿素罐是压力容器,又有腐蚀液体尿素,如盖被人拧下,尿素喷出对人会造成危险,由于螺纹盖是螺纹锁紧,每个紧固点的位置都不一样,无法加定位暗锁(另外,尿素罐须要保压,在盖的中间加暗锁也无法保压)。
技术实现思路
(一)要解决的技术问题本技术要解决的问题是提供一种带注口暗锁机构的气驱尿素罐盖,以克服现有技术中不防松、不带暗锁的缺陷。(二)技术方案为解决所述技术问题,本技术提供一种带注口暗锁机构的气驱尿素罐盖,包括钥匙、锁壳锁芯、锁闩、尿素罐、加注管、盖子和防尘盖;所述加注管上端与所述盖子固定,下端与所述尿素罐固定;所述钥匙与所述锁壳锁芯配合安装在所述盖子一侧;所述锁闩固定在所述锁壳锁芯下端;所述加注管外壁开有与所述锁闩配合的环锁槽;所述防尘盖一端与所述盖子铰接,所述防尘盖另一端与所述锁壳锁芯密封配合。进一步,所述盖子下端一侧且位于锁壳锁芯下端设置有排尘孔。进一步,所述加注管上端与所述盖子内外螺纹旋合固定。进一步,所述带注口暗锁机构的气驱尿素罐盖还包括防脱带,所述防脱带一端与所述加注管卡接固定,另一端与所述防尘盖卡接固定。(三)有益效果本技术的带注口暗锁机构的气驱尿素罐盖,气驱尿素罐盖不易松动、脱落,在尿素罐盖锁孔上面加防尘盖,在防尘盖上加防脱带,防止尿素罐盖拧下时脱落、丢失,确保了气驱尿素罐稳定正常的工作。附图说 ...
