Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, below in conjunction with
Accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clear,
It is fully described by, it is clear that described embodiment is a part of embodiment of this utility model rather than complete
The embodiment in portion.Based on the embodiment in this utility model, those of ordinary skill in the art are not making
The every other embodiment obtained under creative work premise, broadly falls into the scope of this utility model protection.
Embodiment one
The structural representation of the filler cap door lock that Fig. 2 provides for this utility model embodiment.Refer to attached
Fig. 2, the present embodiment provides a kind of filler cap door lock, including: trocar sheath 10 be slidably installed in trocar sheath 10
In lock pin 20, lock pin 20 extends radially outward formation flange 21, one end of trocar sheath 10 towards
Lock pin 20 extends and forms stop part 11, and stop part 11 surrounds the opening 12 stretched out for lock pin, flange 21
Coordinate the axially extended displacement limiting lock pin 20 with stop part 11, stop part 11 is connected with sealing
Circle 30, sealing ring 30 is squeezed between lock pin 20 and stop part 11.
The interior passage that can be formed for lock pin 20 motion of trocar sheath 10, filler cap (not shown),
The lockpin hole coordinated with lock pin 20 can be provided with on filler cap, when filler cap is locked by needs,
Lock pin 20 can be driven to be inserted in the lockpin hole of filler cap, thus realize locking, when needs will refuel
When lid unlocks, lock pin 20 can be driven to exit lockpin hole, and specifically drive the parts that lock pin 20 moves
Can be attached to the bracing wire 40 of lock pin 20 one end, bracing wire 40 can be connected with opening handle, work as operation
When person operates opening handle, bracing wire 40 is driven to move along lock pin 20, i.e. band pendulum lock pin 20 is from lockpin hole
Inside exit, it is achieved unlock.
Being also provided with bracing wire joint 50 on trocar sheath 10, bracing wire joint 50 can be with trocar sheath 10
It is removably secured and connects or one-body molded, here, the present embodiment is not construed as limiting.
Certainly, similarly to the prior art, also may be used between lock pin 20 and trocar sheath 10 or bracing wire joint 50
To arrange back-moving spring 60, by back-moving spring 60, lock pin 20 is not being made by the pulling force of bracing wire 40
Locking is realized in can being inserted into lockpin hole time under with under the driving of back-moving spring 60.
It addition, stop part 11 and sealing ring 30 can be with interference fit, sealing ring 30 difficult drop-off, becoming
In type technique, sealing ring 30 can sulfide with stop part 11, and moulding process is simple, in conjunction with after
Reliable and stable, it is not susceptible to relative movement.
The filler cap door lock that the present embodiment provides, owing to including trocar sheath 10 and being slidably installed in trocar sheath 10
Interior lock pin 20, extends radially outward formation flange 21 on lock pin 20, and trocar sheath 10 is towards lock
Pin 20 extends and forms stop part 11, and stop part 11 surrounds the opening 12 stretched out for lock pin 20, flange 21
Coordinate the axially extended displacement limiting lock pin 20 with stop part 11, stop part 11 is connected with sealing
Circle 30, sealing ring 30 is squeezed between lock pin 20 and stop part 11.Due to by by sealing ring 30 with
Trocar sheath 10 is connected together, and both are connected firmly, sealing ring 30 during lock pin 20 moves
Position will not pursuit movement, and owing to sealing ring 30 is connected firmly with trocar sheath 10, therefore, sealing ring
30 are not easy to deform, and in lock pin 20 motor process, also can play preferable sealing function, add
Oil port cover door lock is difficult to freeze into water, it is ensured that the serviceability of filler cap door lock.
In the above-described embodiments, further sealing ring 30 can include that the first fixed part 31, second is solid
Determine portion 32, and be connected to the press section 33 between the first fixed part 31 and the second fixed part 32, first
Fixed part the 31, second fixed part 32 and press section 33 form the first groove 34 accommodating stop part 11.
Stop part 11 cladding is got up, with stop by first fixed part the 31, second fixed part 32 and press section 33
The contact area in portion 11 is relatively big, and the most whole sealing ring 30 is unlikely to deform, and mounted configuration is relatively stable,
When lock pin 20 moves, the sealing property of sealing ring 30 is stable, good sealing effect.
Further, can also be along the fortune being perpendicular to lock pin 20 in the first groove 34 of sealing ring 30
The second groove 35 is offered in dynamic direction, stop part 11 is additionally provided with for convex with what the second groove 35 coordinated
Go out portion 111.Thus, owing to increasing by the second groove 35 so that sealing ring 30 contacts with stop part 11
Area is bigger, and both fixing after the most firm, sealing ring 30 can more closely be fixed on stop part
On 11, it is less susceptible to deformation and moves, therefore better tightness.
On the press section 33 of sealing ring 30, the surface for contacting with lock pin 20 can also be formed with multiple ring
Shape projection 36, annular protrusion 36 contacts with lock pin 20 extruding.Connect with lock pin 20 by annular protrusion 36
Touching, compared to the mode of sealing ring 30 with lock pin 20 plane contact, sealing effectiveness is more preferable.
Preferably, the quantity of annular protrusion 36 is the spacing phase between three, and each annular protrusion 36
Deng.Spacing between each annular protrusion 36 is equal, is easier to processing, and, owing to having three annulars
Protruding 36, the annular protrusion 36 of timely both sides is deformed, and the annular protrusion 36 being positioned at centre is not easy to
Deformation, it is ensured that the sealing reliability of whole sealing ring 30.
Further, filler cap door lock could be included for the oil filler clamp being fixed on oil filler
70, oil filler clamp 70 is positioned at the one end at stop part 11 place of trocar sheath 10, oil filler clamp 70
On offer the lock pin punched out 71 passed for lock pin 20, the second fixed part 32 is contained in stop part 11
And between oil filler clamp 70, and it is also formed with draining between the second fixed part 32 and oil filler clamp 70
Mouth 80.Hydrops on filler cap door lock can be derived and be gone by this discharge outlet 80, prevents from further refueling
Lid door lock inner inlet, improves the reliability of whole device.
It addition, the hole wall of lock pin punched out 71 on oil filler clamp 70 to lock pin 20 lateral wall away from
From equaling to or more than 0.5mm.And the gap in prior art, between oil filler clamp and lock pin
The least, being generally less than is 0.5mm, and the technical program passes with lock pin by strengthening oil filler clamp 70
Spacing before hole 71, thus prevent capillarity occurring by the external world owing to spacing between the two is less
Water introduces in filler cap door lock, therefore, it is possible to further prevent extraneous water from entering into filler cap
In door lock.
Embodiment two
A kind of automobile, including oil filler and filler cap, install between oil filler and filler cap just like
The filler cap door lock that any of the above-described embodiment is provided.
In the present embodiment, the structure of filler cap door lock is identical, at this no longer with embodiment one with principle
Repeat.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, rather than
It is limited；Although this utility model being described in detail with reference to previous embodiment, this area
Those of ordinary skill is it is understood that the technical scheme described in foregoing embodiments still can be carried out by it
Amendment, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, not
The essence making appropriate technical solution departs from the spirit and scope of this utility model each embodiment technical scheme.
