Abstract
The utility model discloses a double-safety bicycle lock, which is characterized in that a set of chain inserting rod locking mechanism is added in a lock case with a curved rod locking mechanism. The utility model is a double-safety bicycle lock which can fix a bicycle and fix a bicycle body, having the advantages of convenient and flexible use, high safety, and simple structure.
Description
The utility model relates to a kind of double insurance bicycle lock, hereinafter to be referred as Insurance lock.
Existing lock is divided into two classes: a class is to be the fixedly lock of outstanding feature with the knee locking; One class is to be the movable chain lock of sign to insert the mark locking.Fixedly lock can be fixed on the bicycle rear portion, and is easy to use; But it can only stop rear wheel movement, can not stop body movement, is easily moved by the people, inadequately safety.Movable chain lock can not be fixed on the bicycle, does lock and uses conveniently inadequately, but it can make bicycle fasten on heaviness at other, the fixed object, can't push away away, at unmanned place or to lock car night safer.
The purpose of this utility model, provide a kind of can fixed vehicle, fixing vehicle body again, easy to use, safety has the double insurance bicycle lock of the length of two class locks concurrently.
Realize that scheme of the present utility model is as follows: the bolt opening movement direction at the knee lock increases a chain and fixed mechanism thereof, uses a special bolt, makes it also open and close chain lock when opening and closing the knee lock.
The utility model only needs to lock expansion one cover chain fixed mechanism at knee, so simple in structure, cost increases few; But it has the advantage that knee is locked easy to use and chain lock safety concurrently.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Accompanying drawing is the structural representation of an embodiment of the present utility model.
Below in conjunction with details and the working condition of accompanying drawing detailed description according to the double insurance bicycle lock that the utility model proposes.
This lock is mainly by lock core (7), knee locking mechanism (comprising bolt (4), bolt extension spring (1), knee (8), knee extension spring (10)), chain inserted link locking mechanism (comprising the solid seat of bolt (4), bolt extension spring (1), chain inserted link (2), chain (5), chain jack base (3) and chain (6)) and shell (11) are formed.(9) be rivet.Wherein bolt (4) is the critical component of control two cover locking mechanisms, an aperture on its right flank top.The top is the opening movement direction of bolt (4).Chain holder (6) is a solid, be positioned at lock core (7) with the top, be fixed on the lock housing (11), its left end is being fixed chain (5), chain jack base (3) is the tetragonal body that a hole, garden of passing through for the chain inserted link is arranged, be positioned at the top of bolt extension spring (1), be fixed on the lock housing (11).Between chain holder (6) and the chain jack base (3) is the top of bolt (4).The aperture on bolt (4) top can free in and out for the chain inserted link; Bolt (4) is the public and coupling components of two cover mechanisms, its upper end control chain inserted link (2), lower end control knee (8).Lock core is an individual components, is positioned at the left side of bolt (4), the below of chain holder (6), and it and bolt (4) bottom link, and control bolt (4) is up.Bolt extension spring (1) also is the common unit of two cover mechanisms, (one termination bolt (4), another termination rivet, control bolt (4) is descending) be positioned at the right side of bolt (4), the below of chain jack base (3), knee (8) is in lock core (7), bolt (4), the below of bolt extension spring (1).Remove common unit (bolt (4), bolt extension spring (1)), the chain lock locking mechanism is at the first half of lock housing (11), and the knee locking mechanism is positioned at the lock housing Lower Half, and the keying of two mechanisms all is subjected to the control of bolt (4).Bolt is up, and two cover locking mechanisms are all opened, and chain inserted link (2) can free in and out jack and bolt hole.When inserted link (2) in jack and bolt hole, knee (8) moves to the summit along the up time direction under external force, bolt (4) is descending under the effect of bolt extension spring (1), pins inserted link (2) and knee (8) and also drives lock core (7) reposition.Key can take out.When unblanking, key drives lock core (7) rotation, makes bolt (4) up simultaneously, knee (8) is subjected to the motion of knee extension spring (10) effect inhour, and bolt (4) is fixed on up limit, and chain inserted link (2) can be extracted, lock core (7) departs from original position, and key pulls out to come out.
When the user uses the utility model, as chain (5) is passed wheel or other object, just used two cover insurances, otherwise just used a cover insurance, the using method of Insurance lock is roughly the same with general lock, and safety performance is improved.
The most of parts of the utility model are made up of foundry goods and stamping parts, are suitable for producing in batches, and some moulds of former lock can use as usual, so cost is not high.
Claims (3)
1, a kind of double insurance bicycle lock, by lock core (7), the knee locking mechanism, chain inserted link locking mechanism and shell (11) are formed, and it is characterized in that the keying of two cover mechanisms all is subjected to bolt (4) control, and bolt (4) are the public and coupling components of two cover mechanisms.
2, by the described double insurance bicycle lock of claim, it is characterized in that lock core (7) top is chain holder (6), bolt extension spring (1) top is chain jack base (3), and bolt (4) is positioned between chain holder (6) and the chain jack base (3).
3,, it is characterized in that the right upper portion of bolt (4) has an aperture by the described double insurance bicycle lock of claim.
