Description
Affiliated technical field
The utility model belongs to the vehicle fuel tank technical field, particularly relate to a kind ofly be used for, the fuel tank locking cap of heavy-duty vehicle.
Background technology
At present in the general-duty, the fuel tank locking cap on the heavy motor vehicle substantially all is by assembling after the steel moulding, mostly exist seepage oil, loading and unloading power big, do not have the lock fuel tank locking cap and lack defectives such as anti-back structure.As sealing from the lock core leakage of oil serious because of lock core, dead bolt; Because of the unbalance stress of three spring leafs in the fuel lid causes tightening seal washer place seepage oil.Fuel tank locking cap needs two hands to exert oneself simultaneously when loading and unloading, operation inconvenience.
Summary of the invention
The purpose of this utility model be to provide that a kind of sealing property is reliable, in the loading and unloading labour-saving, the heavy goods vehicles fuel tank locking cap.
The technical scheme that the utility model adopted is: a supporting rolling disc is installed in the enclosure, fixedly ring seat is equipped with in supporting rolling disc inboard, fixedly on the ring seat rolling disc is housed, compression spring and ring slider are housed in the rolling disc, the locking mandrel passes the endoporus of compression spring, ring slider and rolling disc successively and is fixed together by screw and shell, the little tightening seal washer that is sleeved on the locking mandrel is arranged in the inboard of supporting rolling disc, fixedly the ring seat outside is set with tightening seal washer, on locking mandrel top the chaining lid is housed.Shell of the present utility model, locking mandrel, fixedly ring seat and rolling disc be by the nylon plastic(s) injection mo(u)lding.
After the utility model adopts said structure,, utilize little tightening seal washer will lock the mandrel outside face and supporting rolling disc endoporus is sealed into one, thereby to be that dividing range has carried out hermetically sealed to support rolling disc with fuel tank locking cap at seal aspect; Aspect the fuel tank locking cap pinch-off seal, utilize claw on the rolling disc and fuel tank to end hydraulic fluid port and position, and utilize the locking mandrel to compress in the wedge surface lift of ring slider; Aspect the anti-back of nothing lock fuel tank locking cap, utilize the falling of locking mandrel boss in the concave surface of the wedge surface lift terminal of ring slider, to realize; Reducing aspect the power of loading and unloading, utilizing the locking mandrel to produce axle pressure, reducing to produce the arm of force of axle pressure, thereby realized that loading and unloading are laborsaving in the rotation of ring slider wedge surface.And most of part such as shell of the present utility model can guarantee its intensity and service life by the nylon plastic(s) injection mo(u)lding, saves raw MAT'L again.

The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a upward view of the present utility model.
Fig. 2 is a front view of the present utility model.
Fig. 3 is a birds-eye view of the present utility model.
Fig. 4 partly cuts open left view for Fig. 1's.
The specific embodiment
In the accompanying drawing illustrated embodiment, be equipped with supporting rolling disc 4 in the shell 1, and utilize the interior snap ring on the shell 1 to be fixed, this is packing assembly A.In the rolling disc 10 that has claw 12, pack into compression spring 7 and ring slider 9 in axial sliding, after will lock mandrel 2 and pass successively in the endoporus of compression spring 7, ring slider 9 and rolling disc 10, in the groove in locking mandrel 2 outsides, this is packing assembly B with the inner hole sleeve of little tightening seal washer 3.In packing assembly A, load onto the fixedly ring seat 5 and the tightening seal washer 11 of band claw 15, in the interior ring of the fixing ring seat 5 of then packing assembly B being packed into, and cross recess thread-forming screw 6 is passed locking mandrel 2 be screwed in the auxiliary hole of shell 1 inner convex platform, load onto chaining lid 8 in locking mandrel 2 ends at last.If the lock core of being opened by key 14 13 also is housed on shell 1, the utility model had both become fuel tank locking cap with lock.In the above-described embodiments, shell 1 of the present utility model, locking mandrel 2, fixedly ring seat 5 and rolling disc 10 all adopt the nylon plastic(s) injection mo(u)lding.
Principle of work of the present utility model is as follows: fixedly three claws 15 on the ring seat 5 be stuck in three breach of oil filling port motionless after, fixedly ring seat 5 and supporting rolling disc 4 promptly are fixed motionless, and other each part rotates along with the rotation of shell 1, three projectioies of rolling disc 10 are slided on the slideway of fixing ring seat 5, stopped by the tank filler opening seam along rise-level and smooth-its three claws 12 of landing curved surface slip back, so far finish first step action, compression spring 7 is compressed-recovers with shell 1 action in this process.Be rotated further shell 1, locking mandrel 2 therewith rotates, and all the other parts are motionless, producing axle pressure after four projectioies its rise in the slideway upper edge of ring slider 9-landing curved surface of locking mandrel 2 slides compresses tightening seal washer 11, finish the action of second step, compression spring 7 is compressed in this process.For fuel tank locking cap with lock, after the second step action is finished, key 14 is clockwise rotated 180 ° lock, its principle is to utilize the pivot pin of welding on the supporting rolling disc 4 to block the semiaxis that is fitted together with lock core 13 to realize to stop shell 1 counter-rotating.
