Top surface has the lug, nib 14 coordinated with the groove 601, when the type of tamper evidence 1 is stretched into the tank filler sleeve 300, described in rotation
Type of tamper evidence is embedded in lug, nib 14, and the groove 601 is interior to be locked in type of tamper evidence 1 in tank filler sleeve 300.Type of tamper evidence 1 of the present utility model
It can be self-locking in tank filler sleeve 300 by lug, nib 14 and groove 601, and elastic component can prevent lug, nib 14 and groove 601
Separation, it is ensured that type of tamper evidence 1 is tightly locked in tank filler sleeve 300, in addition, by pushing type of tamper evidence 1 lug, nib 14 can be made to depart from groove 601
Unlock type of tamper evidence 1, tank filler sleeve 300 can be disengaged it from by then going to type of tamper evidence 1, and therefore, type of tamper evidence of the present utility model can
To be self-locking in tank filler sleeve and can easy removal.
Above-mentioned elastic component in the present embodiment is spring 5, and the lower end of the spring 5, which is supported, to be located on the flange 6, this implementation
Spring 5 is placed in the lower section of above-mentioned sealing ring 4 by example, spring 5 is can contact lubricating oil, prevents that spring 5 from getting rusty failure, increases with this
Its service life.Above-mentioned elastic component is not limited to spring 5, and it can also can produce the bullet along tank filler sleeve axial elasticity power for other
Property structure, as long as it can produce the elastic force along tank filler sleeve axially upwards in type of tamper evidence self-locking, it is ensured that the lug, nib in type of tamper evidence is inserted
It is located in above-mentioned groove.
The effect of to play dust and water protection, the top of above-mentioned type of tamper evidence 1 is arranged with elastic ring 2 in the present embodiment, sees Fig. 1
And shown in Fig. 6, the elastic ring 2 is spacing between the top of tank filler sleeve 300 and type of tamper evidence 1.The present embodiment passes through in tank filler sleeve
Elastic ring 2 is added between 300 top and type of tamper evidence, plays the effect of certain sealing, prevent dust or water enter type of tamper evidence and
Gap between tank filler sleeve；In addition, elastic ring 2 will make to block up in type of tamper evidence and the certain air of oiling interporal lacuna memory storage, those air
There is certain pressure, having prevents type of tamper evidence from shaking, and is also prevented from type of tamper evidence and departs from tank filler sleeve between plug member and tank filler sleeve.This implementation
Elastic ring 2 in example is the flat lasso with certain axial width, as shown in Figure 6.
For ease of the installation of type of tamper evidence, the top of above-mentioned type of tamper evidence 1 has the blind hole of installation in the present embodiment, can will be auxiliary
Help in installation tool insertion blind hole, be easy to that type of tamper evidence is pressed in tank filler sleeve to and is easy to the rotation self-locking of type of tamper evidence.
For ease of installing above-mentioned sealing ring 4 and elastic ring 2, the concrete structure of the type of tamper evidence in the present embodiment as shown in Figure 4,
Type of tamper evidence in the present embodiment has two circumferential slots in the circumferential, and circumferential slot 11 above is used to be arranged elastic ring 2, position
Circumferential slot 12 in lower section is used to be embedded sealing ring 4, and the lower section of underlying circumferential slot 12 is that type of tamper evidence 1 can be by above-mentioned
The bottom of special-shaped via 600, the bottom of type of tamper evidence 1 have the boss 15 radially extended, have lug, nib 14 in the top surface of boss 15,
And there is the bottom for being easy to type of tamper evidence to insert special-shaped via and the baffle plate 13 for preventing type of tamper evidence to be rotated further in the side of boss,
Baffle plate 13 is axially arranged along type of tamper evidence.
Special-shaped via 600 in the present embodiment is by center hole and the fan-shaped arc groove string for being symmetricly set on center hole both sides
It is logical to form, as shown in Fig. 2 and Fig. 3.The setting of fan-shaped arc groove is easy to the bottom of type of tamper evidence to insert, and above-mentioned baffle plate 13 and sector
The edge mate of arc groove can make type of tamper evidence stop operating.Groove 601 in the present embodiment is two groups, is symmetrically arranged at above-mentioned
Corresponding on the hole periphery of center hole, the lug, nib 14 in above-mentioned type of tamper evidence 1 is also two groups.
To realize the tightening seal to tank filler sleeve inner fluid, above-mentioned sealing ring 4 is O-ring, as shown in Figure 5.
For ease of the above-mentioned type of tamper evidence of installation, in the present embodiment, fuel door 3, which is provided with, prompts what the type of tamper evidence 1 was installed in place
Mark 7, the mark 7 in the present embodiment is a haircut, rotates type of tamper evidence according to the haircut direction, when the surface of type of tamper evidence 1 anyhow
When line flushes with haircut, represent type of tamper evidence and rotate in place.
The process of above-mentioned type of tamper evidence installation and removal is specific as follows：During installation, the bottom of type of tamper evidence 1 is directed at tank filler sleeve
300, and make, with type of tamper evidence 1 is forced, to block towards the fan groove direction in above-mentioned special-shaped via at the boss 15 in type of tamper evidence 1
The bottom of part is discharged by above-mentioned special-shaped via, rotation type of tamper evidence 1 to that can not rotate (above-mentioned baffle plate 13 can control rotation amount)
Pressure, in the presence of spring 5, type of tamper evidence 1 moves up, and the lug, nib 14 in type of tamper evidence 1 can take advantage of a situation into the groove of tank filler sleeve bottom surface
In 601.Because lug, nib 14 and groove 601 are engaged, spring 5 and sealing ring 4 have certain prevention type of tamper evidence 1 rotatably to make
With so type of tamper evidence 1 is not susceptible to rotate and come off.
During dismounting, above-mentioned type of tamper evidence 1 is pressed down on, rotation type of tamper evidence 1 discharges pressure to that can not rotate, and the meeting of type of tamper evidence 1 exists
Automatic spring in the presence of above-mentioned spring 5.
In summary, fuel door of the present utility model, type of tamper evidence and tank filler sleeve can be by lug, nibs and groove in elastic component
Ensure that type of tamper evidence realizes self-locking under elastic force, and tightening seal is realized to tank filler sleeve by sealing ring, additionally by under aid
Press type of tamper evidence and reversely rotate and type of tamper evidence can be removed out of tank filler sleeve, complete the dismounting of type of tamper evidence, therefore, the utility model
Not only the sealing of tank filler sleeve had been ensure that but also easily disassembled type of tamper evidence.So the utility model effectively overcomes kind of the prior art
Plant shortcoming and have high industrial utilization.
Above-described embodiment only illustrative principle of the present utility model and its effect are new not for this practicality is limited
Type.Any person skilled in the art can all be carried out without prejudice under spirit and scope of the present utility model to above-described embodiment
Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the essence disclosed in the utility model
God and all equivalent modifications completed under technological thought or change, should be covered by claim of the present utility model.
