Background technology
The AGO Automotive Gas Oil case under the situation that high temperature or sun lights are shone, the fuel oil expansion of can volatilizing in the case, tank internal pressure is too high, can damage fuel tank, or when opening fuel lid, fuel oil sprays outward in the fuel tank, very dangerous, so fuel tank must be equipped with safety valve, perhaps in fuel lid, dispose safety valve.At present, fuel lid safety valve commonly used adopts spring pressing ball, and ball withstands on breather hole place set on the fuel lid, and still, the safety valve volume of this scheme is bigger, and sealing property is relatively poor.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is a kind of rational in infrastructure that the utility model provides, the better fuel lid of safety performance and sealing effectiveness.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of fuel lid, include and cover shell, the lock of captiveing joint with the lid shell, install the lock body on lock, and install lock core and safety valve on lock body, it is characterized in that: described safety valve includes the safety valve valve body, the safety valve rubber ring, safety valve spring and safety valve valve gap, safety valve valve body and lock are fixed, be provided with the safety valve containing cavity in the safety valve valve body, the safety valve valve gap is covered on the safety valve valve body, offer the safety valve valve opening that runs through safety valve valve gap and safety valve valve body on safety valve valve gap and the safety valve valve body respectively, safety valve rubber ring and safety valve spring are installed successively in the safety valve containing cavity, one side of safety valve rubber ring and safety valve valve opening formation are sealed and matched, one end of opposite side and safety valve spring is inconsistent, and the other end of safety valve spring contacts in the safety valve containing cavity near the safety valve valve opening place of covering shell.
Adopt technique scheme, safety valve passes through safety valve valve body, safety valve rubber ring, safety valve spring and safety valve valve gap, the ball that the safety valve rubber ring is more traditional, and sealing effectiveness is better, makes that like this safety performance of the present utility model is higher.
Of the present utility modelly further be set to: the described vacuum valve of installing on lock that also includes, vacuum valve is fixedly arranged on the lock again.Wherein, described vacuum valve includes the vacuum valve valve body, the vacuum valve rubber ring, vacuum valve spring and vacuum valve valve gap, vacuum valve valve body and lock are fixed, be provided with the vacuum valve containing cavity in the vacuum valve valve body, the vacuum valve valve gap is covered on the vacuum valve valve body, offer the vacuum valve valve opening that runs through vacuum valve valve gap and vacuum valve valve body on vacuum valve valve gap and the vacuum valve valve body respectively, vacuum valve rubber ring and vacuum valve spring are installed successively in the vacuum valve containing cavity, one side of vacuum valve rubber ring and vacuum valve valve opening formation are sealed and matched, one end of opposite side and vacuum valve spring is inconsistent, and the other end of vacuum valve spring contacts at the vacuum valve valve opening place of close lock in the vacuum valve containing cavity.
Adopt technique scheme, vacuum valve the further safety performance of the present utility model that improved is set, when occurring the situation of vacuum in the fuel tank, vacuum valve can be from outside aspirated air under pressure, thereby keeps the inside and outside weighing apparatus that flattens, and avoids occurring safety misadventure.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the cutaway view of the utility model embodiment.
Fig. 2 is the A portion enlarged drawing of Fig. 1.
Fig. 3 is the B portion enlarged drawing of Fig. 1.
The specific embodiment
As Figure 1-3, present embodiment include and cover shell 1, with lid shell 1 lock 2 of captiveing joint, install in the lock body on the lock 23 and install lock core 4, safety valve 5 and vacuum valve 6 on lock body 3.Described safety valve 5 includes safety valve valve body 51, safety valve rubber ring 52, safety valve spring 53 and safety valve valve gap 54, safety valve valve body 51 is fixing with lock 2, be provided with safety valve containing cavity 511 in the safety valve valve body 51, safety valve valve gap 54 is covered on the safety valve valve body 51, offer the safety valve valve opening 55 that runs through safety valve valve gap 54 and safety valve valve body 51 on safety valve valve gap 54 and the safety valve valve body 51 respectively, safety valve rubber ring 52 and safety valve spring 53 are installed successively in safety valve containing cavity 511, one side of safety valve rubber ring 52 and safety valve valve opening 55 formations are sealed and matched, one end of opposite side and safety valve spring 53 is inconsistent, and the other end of safety valve spring 53 contacts in the safety valve containing cavity 51 near safety valve valve opening 55 places of covering shell 1.In addition, described vacuum valve 6 includes vacuum valve valve body 61, vacuum valve rubber ring 62, vacuum valve spring 63 and vacuum valve valve gap 64, vacuum valve valve body 61 is fixing with lock 2, be provided with vacuum valve containing cavity 611 in the vacuum valve valve body 61, vacuum valve valve gap 64 is covered on the vacuum valve valve body 61, offer the vacuum valve valve opening 65 that runs through vacuum valve valve gap 64 and vacuum valve valve body 61 on vacuum valve valve gap 64 and the vacuum valve valve body 61 respectively, vacuum valve rubber ring 62 and vacuum valve spring 63 are installed successively in vacuum valve containing cavity 611, one side of vacuum valve rubber ring 62 and vacuum valve valve opening 65 formations are sealed and matched, one end of opposite side and vacuum valve spring 63 is inconsistent, and the other end of vacuum valve spring 63 contacts at vacuum valve valve opening 65 places of close lock 3 in the vacuum valve containing cavity 611.Above-mentioned safety valve rubber ring 52 and vacuum valve rubber ring 62 are the disk shape structure that rubber is made, and when being located on the valve opening, can well seal applying with the valve opening edge when stifled, reach the sealing effectiveness of the best.
