Abstract

The utility model relates to a safety device for bicycle. An existing crab tongs lock is easy to be prized, and the security is poor. A chain lock is inconvenient to carry and use, and is not beautiful in appearance. The utility model is characterized in that a crab tongs lock and a chain storing mechanism are arranged on the same bottom board; a lock core of a locking head is provided with two toggle mechanisms which respectively control the hard ring of the crab tongs lock and the plug in the chain storing mechanism. The chain storing mechanism comprises a rolling core, a pin, a rolling spring, a rolling ring, a chain, a plug, a guiding nozzle and a non-return hook, so that the chain can be hidden in the chain storing mechanism when not using, and the chain is only pulled out and inserted into the locking head when using. The double rings lock has the advantages of easy use, high safety and beautiful appearance.

Description

Cycle double rings lock

The utility model relates to a kind of for bicycle protective device, and it is applicable to Regular Bicycle.

Be applicable in the prior art that the lock that uses on the bicycle mainly contains two kinds, a kind of is the crab claw lock that is fixedly mounted on the bicycle, another kind of travel lock in the form of a chain.Although it is easy to use for crab claw locks, owing to prized easily, its fail-safe is relatively poor.And the chain type travel lock, although it is mainly used in travelling, because it also can be applicable to other occasion and is difficult for again being pried open, so, be applied in the bicycle, but this lock is not specially for bicycle designs after all yet, so its use with carry all very inconvenient, and not attractive in appearance when using.

The purpose of this utility model is to avoid existing above-mentioned deficiency in the prior art, and a kind of bicycle Two-ring lock of easy to use, the good and good looking appearance of security personnel's performance is provided.

The purpose that the utility model proposed can be achieved through the following technical solutions: this Two-ring lock is hidden the two large divisions of mechanism by crab claw lock and chain roll and is formed, this two large divisions is installed on the same base plate, tapered end in the crab claw lock is on the basis of inheriting the common spring lock, on lock core, be provided with two toggle mechanisms, control hard ring in the crab claw locks and chain roll respectively and hide chain plug in the mechanism; Be milled with the key of evagination at the tail end of lock core, it matches with the slotted eye of locking plate, to drive locking plate deflection, simultaneously, design has a flange, this flange to be engaged in the groove of dead bolt on lock core, lock core can be stirred the dead bolt displacement, and inclined wedge-shaped is made in the end of dead bolt, so that block the chain plug.

Description of drawings is as follows:

Fig. 1, Fig. 2, Fig. 3 are three kinds of locking states figure of the utility model.

Fig. 4 is installed in structural representation on the bicycle for the utility model.

Fig. 5 is an A-A sectional view of the present utility model.

Fig. 6 is a B-B sectional view of the present utility model.

Fig. 7 is a C-C sectional view of the present utility model.

Following the utility model will be further described by embodiment.

Referring to Fig. 1, this Two-ring lock is hidden mechanism's II by crab claw lock I and chain roll and is formed, they are installed on the same base plate 1, crab claw lock I is made up of hard ring body 2 parts and tapered end 3 parts again, long or stop ground when safer when the car time of staying, only need to encircle firmly 4 and lock and get final product, the crab claw of its using method and ordinary bicycle are phase-locked together, at this moment, chain roll Tibetan mechanism II is not worked.

Referring to Fig. 2, when the time of staying of bicycle was longer, except that hard ring 4 was locked, also the chain 5 that chain roll can be hidden in mechanism's II was pulled out, and inserted in the tapered end 3 by plug 6, carried out two rings with lock.

Referring to Fig. 3, except that above two kinds of locking states, the chain 5 in this Two-ring lock also can be interlocked with foreign object 7, and this foreign object 7 can be a fixture, also can be other bicycle, or the like.

Referring to Fig. 4, this Two-ring lock is mounted on the rear pole 8 of bicycle tripod, be positioned at the inside front of bicycle rear 9, utilize the flat groove 16 on the lower cover shell 10, (see figure 5) is locked the I partial fixing by intermediate plate 11 and screw 12 on rear pole 8 with the crab claw, simultaneously, utilize the through hole (see figure 7) at volume core 17 centers on the shell of top cover 13,, chain roll is hidden mechanism's II be fixed on the rear pole 8 by cross-arm 14 and screw 15.Certainly, upper and

lower cover shell

13,10 also can be designed to an integral body.

Referring to Fig. 5, Fig. 6, this two figure has described the concrete structure and the operating principle of tapered end 3, tapered end 3 is made up of lock body 18, lock core 19, dead bolt 20, locking plate 21 and spring 22,23,24, tapered end 3 is on the basis of inheriting the common spring lock, on lock core 19, be provided with two toggle mechanisms, respectively hard ring 4 of control and chain plug 6; On the tail end of lock core 19, mill into the key of evagination, it matches with the slotted eye 30 of locking plate 21, and it is fastening with screw 31, lock core 19 can drive locking plate 21 deflections, spring 23 1 ends are fixed on the lower cover shell 10, the other end tangles an end of locking plate 21, encircles firmly to have glossal canal 25 on 4 outer walls, makes the tapered end of locking plate 21 can block this glossal canal 25; One flange 26 is arranged on lock core 19, this flange 26 is engaged in the groove of dead bolt 20, lock core 19 can be stirred dead bolt 20 displacements, spring 24 pushes away dead bolt 20 forward, inclined wedge-shaped is made in dead bolt 20 ends, make plug 6 utilize the inclined-plane slippage of dead bolt 20 and insert in the lockhole 27, dead bolt 20 blocks plug 6 by the thrust of spring 24.

Lock is during car, only need press manually by sheet 28 to locked position, encircle firmly 4 just locking bicycle, at this moment, spring 29 is stretched, and is in tensioning state.Then, catch plug 6, pull out the length of chain 5 at needs, plug 6 is inserted in the lockhole 27, then dicyclo is with lock.During driving, key inserted unblank in the keyhole to get final product.

Referring to Fig. 7, chain roll is hidden mechanism's II and mainly is made up of volume core 32, pin 17, wind spring 33, volume ring 34, chain 5, plug 6, guiding mouth 35, non-return hook 36 and spring 37,32 rivetings of volume core are by on base plate 1, the pin 17 of one end evagination is housed on it, wind spring 33 is placed in the volume ring 34, and makes wind spring 33 inner fixing by pin 17.There is an ear circle 38 outer end of wind spring 33, and this ear circle 38 stretches out outside the volume ring 34, with the 5 ' socket of chain 5 tail ends one ring, tightens wind spring 33, and wind spring 33 just can be put torsion to good use and be driven volume ring 34 and clockwise rotate, and the ear circle 38 of wind spring 33 just drives chain 5 and inwardly moves.Chain 5 through guiding chew 35 pat after, entirely be wound on ring 34 the outer garden, all involve in until chain 5, plug 6 withstands guiding and chews 35 and just stop.Non-return hook 36 is a unidirectional stop mechanism, when chain 5 is pulled outwardly, and spring 37 compressions, 36 perks of non-return hook, chain 5 can be pulled out smoothly; During wind spring 33 drag chain bars 5 past retractions, spring 37 presses down non-return hook 36, and insert in any ring of chain the end, stops chain 5 to fall back.Have only with hand pressing non-return hook 7 afterbodys, make 36 perks of non-return hook, chain 5 could be crispaturaed in the shell of top cover 13.

The utility model compared with prior art has the following advantages: easy to use, security personnel's performance is good, and good looking appearance integrates the advantage of crab claw locks and chain lock.
