Abstract

The utility model relates to a rotary fuel tank lock which is used on a motorcycle fuel tank. A lock core of the utility model is arranged on a cover seat which rotates relative to a lock seat. A waterproof protective cover is pivoted on the cover seat. The inner end of the lock core is linked with a positioning ring with a positioning point. The inner side of the lock seat is correspondingly provided with a fixed positioning ring with a positioning point. The positioning ring is butted against the fixed positioning ring by a spring in normal state.

Description

Rotary tank cap lock

The utility model relates to a kind of rotary tank cap lock, refers to a kind of rotation tank cap lock that is applicable to motorcycle tank especially.

Though the existing attached lock of existing fuel tank cap, but mostly be directly to be fixed on the fuel tank cap with core, the locking bolt of core end then extends the fuel tank cap outer rim and locks and pull, so, when unblanking, powerful rotation is to open fuel tank cap after all inserting core with key, quite require great effort, simultaneously, because of rotation effort, locking does not reach the location often and can't extract key or extract the location, rear and can't lock once more, simultaneously, no water-proof function not only causes garage after uneven road surface, the trouble that fuel tank cap is promptly lost and the worry of moisture content infiltration is also arranged.

The purpose of this utility model is promptly providing a kind of rotary tank cap lock, its protecting cover can be pinched with being held by the user with the key that inserts core after upright lifting, and locating ring is established so that can locate and send the sound after core goes to the location in core the inner, so reach cause can light power the fuel tank cap and can go to effect such as location really of outwarding winding.

The technical solution of the utility model is:

A kind of rotary tank cap lock, comprise core, cage, protecting cover, lock, locating ring, spring and core tube, it is characterized in that: this protecting cover and cage articulate, and cage places again on the lock pivotly, and core is set in cage and the lock, core passes the then sheathed locating ring in end, spring and the core tube of lock, and core and core tube inlay card, core tube inlay card locating ring, and locating ring is provided with the anchor point of the corresponding lock wall of anchor point side.

Described rotary tank cap lock is characterized in that: this protecting cover bottom surface is provided with lug, and this lug is located in the arc groove corresponding above the lock pivotly.

Described rotary tank cap lock is characterized in that: an arc wall is established in this lock bottom surface, and cooperates a stationary positioned ring, on this stationary positioned ring correspondence be provided with an arc groove and build-in in the lock bottom surface, and, set the anchor point of site on the stationary positioned ring with corresponding locating ring.

Effect of the present utility model is:

Waterproof protecting cover of the present utility model can lift upright, and when key inserted in core, the user can grip protecting cover and key simultaneously, and unblanks easily, and utilize anchor point correspondence on the locating ring to support anchor point on the locking closure, and then after core goes to fixed point, send tap-tap and location.

To sum up state, this is created true tool and can be convenient to operation and operate the effect that can warn the user.

In order to be easier to understand the architectural feature and the effect of the utility model, details are as follows to cooperate illustrated embodiment now:

Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of this creation.

Fig. 2 is the textural association schematic diagram of this creation.

Fig. 3 implements view for this creation.

As shown in Figure 1, 2, this creation system is made of core 1, cage 2, protecting cover 3, lock 4, stationary positioned ring 5, locating ring 6,

spring

7 and 8 in core tube, wherein:

Core 1 end can be established a C clasp 11 and wear pivot on lock 4; In addition, it is to open with key 12;

Cage 2 bottom surfaces are provided with lug 21, and the bottom surface is provided with a shell fragment 22 in addition, and cage 2 central authorities are provided with a post hole, rank 23 of running through being installed with core 1, and cage 2 is pivoted with waterproof protecting cover 3, and the pivot joint end of this protecting cover 3 can be supported and shell fragment 22;

Lock 4 central authorities are provided with the lock core hole 401 that runs through, and are the post hole that two ends are fish eyelet, and nearly outer rim is provided with arc groove 403 above the lock 4, and are provided with arc wall 402 below the lock 4; Other arrange in pairs or groups accessories such as O type ring 41, packing ring 42, O type ring 43, packing ring 44 and using;

The arc wall 402 of the corresponding lock 4 of a side on the stationary positioned ring 5 and be provided with concave arc 51, and stationary positioned ring 5 is provided with an amount of

anchor point

52,53.

Locating ring 6 outwards convexes with locking bolt 61, and locking bolt 61 is provided with anchor point 611, and is provided with anchor point 62 in addition on the locating ring 6; Anchor

point

611 and 62 is corresponding to

aforementioned anchor point

52,53, and above-mentioned

anchor point

611,62,52,53 is a waveform;

Core tube 8 is a tubular, and the barrel side is provided with the locking bolt 61 of breach 81 with corresponding locating ring 6; Again, being provided with lug in the core tube 8 in addition can be integrated with core 1 admittedly to be mounted on the core;

Mat it, two

O type rings

41,43 and packing ring 42 are embedded in lock core hole 40.1 two ends of lock 4 earlier, cage 2 then with the lug 21 embedding cunnings of its bottom surface in the arc groove 403 of lock 4, and its post hole, rank 23 correspondences lock core hole 401, mat it, core 1 is worn and is embedded in post hole 23, rank and the lock core hole 401; The packing ring 44 of other other nested another glue system of lock 2 bottom surfaces, respectively stationary positioned ring 5 and locating ring 6 are nested in outside the core 1 again, and concave arc 51 on the stationary positioned ring 5 with arc wall 402 corresponding build-ins, anchor point 52 on stationary positioned ring 5 and the locating

ring

6,53 and 611,62 in correspondence with each other, and spring 7 also is placed in outside the core, and an end circle is supporting locating ring 6, again, 8 correspondences of core tube and the enclosure are outside core 1, and lug buckle core 1 with interlock with it in it, and 81 pairs of its breach stick the locking bolt 61 of locating ring 6, and it is terminal and make up all members to buckle the kayser heart 1 with C clasp 11 at last; Mat it, but when core 1 rotates interlock locating ring 6 and locking bolt 611; Again, setting fastening was stuck in wall within the reservoir port when locking bolt 611 used, and commonly used therewith together, did not describe in detail.

When start as shown in Figure 3, when lifting upright protecting cover 3, after inserting key 12, pinch with hand and to hold waterproof protecting cover 3 and key 12 and rotation lock core 1 and protecting cover 3 (with its lug 21 slippage in arc groove 403) synchronously, show light power, promptly, because of gripping surface greatly is easy to the application of force, again, when core 1 and locating ring 6 rotations, because of

anchor point

611 and 62 is to regard to stationary positioned ring 5 to be salient point, so by " jack-up " slippage, to reaching

anchor point

52,53 o'clock (being concave point relatively), then fast power because of spring 7 are supported fixed " location ", and send clatter sound, make the existing sense of touch of user have the sense of hearing to reach the location again to remind the user.
