The utility model relates to an oil tank lock for balancing the air pressure of an oil tank, which comprises a lock body, a lock core and a cover surface. The lock core can be movably installed in the lock body. The lock body is fixed and sealed in the cover surface. One end of the cover surface is provided with a lock eye sliding cover, the other end is provided with a sealing rubber ring, and the lock body is also provided with an air ventilation device, which includes positive and negative pressure valves, and the positive pressure valve contains an oil tank air opening, an external air opening and a positive pressure valve. The valve body, the valve body is provided with an elastic chamber, and the elastic chamber is provided with elastic parts. One end of the elastic parts corresponds to the gas port of the oil tank, the other end corresponds to the gas port of the oil tank. There is a sealing ball between the gas port of the oil tank and the elastic parts to seal the gas port of the oil tank. The beneficial effect of the utility model is that the lock body of the utility model is provided with positive and negative pressure valves to balance the gas pressure of the oil tank, when the gas tank is filled. When the pressure is balanced with the external air pressure, the positive and negative pressure valves in the lock body can prevent blockage of air holes and eliminate the potential safety hazards caused by the change of air pressure in motorcycle fuel tank.
【技术实现步骤摘要】
一种平衡油箱气压的油箱锁
本技术涉及一种油箱锁,具体涉及一种平衡油箱气压的油箱锁。
技术介绍
油箱锁具有闭锁油箱管口的功能,防止油箱内的汽油泄漏,但是油箱在热胀冷缩的过程中,油箱内的气压存在变化,为了防止气压变化而使得油箱变形,油箱锁不能密封,必须要留出一个进出气孔,但传统油箱锁的进出气孔是没有什么保护的,并且由于进出气孔设置于油箱盖的上端,通过进出气孔与油箱锁底部的进出气阀相连,这样灰尘、冰雪等杂物易从端面掉落到进出气孔,或是水落入进出气孔结冰,都会造成对进出气孔的堵塞。当发动机在工作的时候,油泵会不断的从油箱抽油,而由于油箱的进出气孔已被堵塞,外界空气无法补充到油箱内部,油箱里就会形成一个真空,由于油箱承受的压力有限,油箱就会被吸瘪;如果油箱被暴晒或在温度升高的情况下,引起油箱内部压力升高,易引起油箱发鼓,甚至引发油箱开裂漏油,导致安全事故。
技术实现思路
本技术所要解决的技术问题在于针对上述现有技术的不足,提供一种平衡油箱气压、防止气孔堵塞消除安全事故的油箱锁。为实现上述目的,本技术提供了如下技术方案:一种平衡油箱气压的油箱锁,包括锁体、锁芯和盖面,所述锁芯可活动装设在锁体内,所述锁体固定密封套设在盖面内,所述盖面一端设有锁眼滑盖,另一端设有密封胶圈,其特征在于:所述锁体内还开设有通气装置,所述通气装置包含正压阀与负压阀,所述正压阀包含有油箱气口、外气口和阀体,所述阀体内开设有一个上窄下宽的弹性件容置腔,所述弹性件容置腔与油箱气口和外气口相通,所述弹性件容置腔内设有弹性件,所述弹性件一端与油箱气口相抵,另一端与外气口相抵,所述油箱气口与弹性件之间设有对油箱气 ...
