Abstract
The utility model relates to a motor vehicle lock which belongs to a lock-plate type lock. Lock plate grooves which are arranged in the core of the lock are arranged by axial symmetry of 180 DEG, and lock plates are inserted into the lock plate grooves on the axial symmetry direction of 180 DEG. The utility model has the advantages of simple fabrication, low cost and convenient operation. Because the lock plates are arranged by axial symmetry of 180 DEG, both faces of a key are clung by the lock plates. Thereby, the rate of mutual opening of the lock is decreased. The motor vehicle lock can be widely used as the car door lock, the oil tank lock, the container lock, the direction machine lock of an ignition switch, etc.
Description
The utility model relates to the lock that a kind of automobile is used.
Existing automotive lock can be divided into cylinder type lock or locking plate formula lock.Intensity, the precision of cylinder type lock are all better, and mutual opening rate is also lower, but because of lock core, lock core shell and pellet shot from a slingshot all adopt brass material, processing technology complexity, cost is higher.So progressively processed good manufacturability, the low locking plate formula easy to use lock of cost replaces.But locking plate formula lock mutual opening rate is higher.Because the locking plate groove in the locking plate formula lock is opened the same direction at lock core, locking plate meshes with lock housing under the effect of locking plate spring in the same direction.When the double cog key of different coding inserted lock core, locking plate only touched double cog key one side under the effect of the spring in the locking plate groove.Therefore, as long as solve the locking plate height of a direction, lock just easily is opened.
The purpose of this utility model is the defective that is latched at above-mentioned locking plate formula, provides a kind of cost low, easy to use to society, and mutual opening rate is low, the automotive lock that theftproof performance is good.
The utility model is made up of institutes such as lock core, lock core shell, key, locking plate, locking plate spring, swinging plates.Locking plate groove in lock core is arranged with 180 ° of axial symmetry, and locking plate is corresponding to be assigned in the locking plate groove with 180 ° of axial symmetry.One end of locking plate groove is placed spring, makes locking plate under the effect of spring, when closure state, simultaneously with lock core two limit engagement.During unlatching, insert key, corresponding with each locking plate coding as the tartar coding of key, each locking plate just is in the lock core, and promptly lock core can rotate with respect to lock core shell, and when turning clockwise, lock core drives swinging plate, can open lockset.
The adjacent locking plate groove of in the lock core each can be arranged with 180 ° of axial symmetry, and each adjacent locking plate assigns in these locking plate grooves with 180 ° of axial symmetry; Locking plate groove in the lock core also can be to make one of them or arrange with 180 ° of axial symmetry with other locking plate groove more than one, and assigns corresponding locking plate.
The utility model belongs to locking plate formula lock, and processing is simple, and cost is low, and is easy to use, and in lock core the symmetry film trap of unblanking, make locking plate become 180 ° of axial symmetry to settle, locking plate is under the effect of spring like this, the two-sided of key all has locking plate to touch.The key tooth flower coding increases simultaneously, just greatly reduces mutual opening rate.
Fig. 1 is the structural representation of the utility model automotive lock.
Fig. 2 is that the utility model automotive lock key inserts the schematic diagram of working after lock core is opened.
Fig. 3 is the A-A sectional view that removes lock core shell etc. among Fig. 2.
Fig. 4 is the B-B sectional view that removes lock core shell etc. among Fig. 2.
Accompanying drawing is an embodiment of the present utility model, describes the utility model structure and using method in detail below in conjunction with accompanying drawing.
On the lock core (6) of a column type, have six locking plate grooves (15), each adjacent locking plate groove (15) is arranged with 180 ° of axial symmetry, one end of each locking plate groove (15) has an imperforate small garden hole, in each small garden hole, lay locking plate spring (8), locking plate (7) is with 180 ° of corresponding assigning in the locking plate groove (15) of axial symmetry, and makes the outstanding tip of locking plate aim at locking plate spring (8).There is a lock core shell (9) outside of lock core (6), and this inner walls has and is mutually axisymmetric groove (16), during locking and locking plate engagement.On a groove, have rhone (17).Hole, a garden is arranged on the lock core shell, place steel ball (12), steel ball and spring (11) and cover plate (10) on it, with the position of restriction key turnover.The key upstream end of lock core is equipped with a dust excluding plate (4), and dust excluding plate withstands lock core cover (3) and end cap (2) under the effect of dust excluding plate torsion spring (5), can seal lockset and play dustproof effect.The other end of lock core is equipped with a swinging plate (13), and fixing with it with jump ring (14).Swinging plate (13) is connected with the lockable mechanism of lock body.During use, key (1) is inserted lock core (6), corresponding with each locking plate coding as the tartar coding of key, each locking plate just is placed in the lock core.Turn clockwise, because the rotation drive of lock core and the swinging plate (13) that lock core fixes also drive lockable mechanism simultaneously, lockset can be opened.Be rotated counterclockwise with key, when locking ball is located, transfer to key, each locking plate is meshed to the lock core shell groove with axial symmetry under the effect of locking plate spring simultaneously, promptly pins lockset.
Locking plate groove in this automotive lock lock core, also can make one of them or arrange with 180 ° of axial symmetry with other locking plate groove more than one, and assign corresponding locking plate, make one of them or each locking plate of more than one locking plate and other become 180 ° of axial symmetry, make locking plate under the effect of spring, the two-sided of key all has locking plate to touch.
This automotive lock can be widely used as for automobile door lock, tank cap lock, baggage compartment lock, with Direction machine lock of ignition switch etc.
