Abstract

The utility model relates to a bicycle head dormant lock for vehicles. The utility model adopt s mechanical structure to control the rotation of a direction column. The utility model utilizes the limited space of the inner part of the existing direction column to cause a whole lock body which comprises a universal lock core, a moving drive mechanism which is connected with the universal lock core, and a bolt which can be telescoped under the control of the driving device to be arranged in the existing direction column. The side wall of the direction column is provided with a gap where the bolt can be telescoped, which causes the bolt is transversely arranged at the point of the gap corresponding to a shaft sleeve of the direction column of a vehicle frame when the utility model is locked. When the direction column is twisted at an angle to be fixed to provide an anti-prizing dormant lock for storing vehicles.

Description

Bicycle head dormant lock

The utility model relates to a kind of physical construction Bicycle head dormant lock of transportation means, and this built-in lock can not rotate headstock in order to the locking direction post.

The preceence of built-in lock is well-known, and dead bolt is built-in, makes the robber have no way of doing it, and has been widely used in every field such as door lock, drawer lock, strong box.And just having increased the impregnability of lock itself, existing various pick-proof vehicle lock generally all belongs to bright lock, though the head lock of motor bike is fixed under the direction base for post, but fixed position intuitively as seen, also belong to bright lock, though (electric door lock of motor bike belongs to built-in lock, because of lock mode is that circuit is not at the row of the utility model discussion), because bright lock lock body exposes, cartheft adopts destructive means (as with reinforcing bar pincers, hacksaw etc.) all can to pry open at short notice, so in order to overcome the shortcoming of bright lock, improve the safety of depositing car, need a kind of automobile-used built-in lock.In this specification and claims book unless otherwise indicated outside, car refers to the transportation means of service orientation posts such as bicycle, three-wheel vehicle, motor bike control front-wheel directions, parts such as direction post, front fork, vehicle frame, head lock refer to described transportation means used unit.

The purpose of this utility model provides a kind of automobile-used built-in lock for the customer exactly, and lock is built in car body inside, realizes pick-proof, safety.

The implementation of the utility model Bicycle head dormant lock is: Bicycle head dormant lock is made of the lock body in housing and the housing, make full use of existing direction column jecket material in-to-in finite space, to comprise that the general lock core of general lock core and this is connected the transmission device of motion and the dead bolt of scalable action under this transmission mechanism control at interior whole lock body, place direction column jecket material inner space, described housing is made of this direction post, having on direction post sidewall can be for the flexible breach of dead bolt, dead bolt lies across this breach and the vehicle frame steering column overlaps corresponding indentation, there when making locking, headstock was fixed after turning round an angle, reached lock car purpose.When unblanking, insert key and rotate general lock core rotor and drive the dead bolt state that goes out of lock through embedded transmission mechanism, headstock rotates freely.

The utility model Bicycle head dormant lock, behind the car body of packing into, cartheft is had no way of doing it in the short time, more can't pry open with destructive means, plays the effect of pick-proof, makes to park cars saferly, and built-in lock makes outward appearance simpler and more direct, attractive in appearance.

Fig. 1 is the structural representation of ordinary bicycle direction post and front fork.

Fig. 2 is the structural representation of mountain bike direction post and front fork.

Fig. 3 is the structural representation of direction column of motorcycle and front fork.

Fig. 4 is one of the utility model embodiment, is to be housing design-calculated Bicycle head dormant lock assembling part sectional view with direction post shown in Figure 1.

Fig. 5 is two of the utility model embodiment, is to be housing design-calculated Bicycle head dormant lock part sectional view with direction post shown in Figure 2.

Fig. 6 is the side partial sectional view of Fig. 5.

Fig. 7 is three of the utility model embodiment, is to be housing design-calculated Bicycle head dormant lock part sectional view with direction post shown in Figure 3.

Three kinds of typical structures of analysis chart 1, Fig. 2, existing direction post shown in Figure 3 and front fork, as can be seen, vertical pivot pipe [1] and pedestal [2] that the direction post is made by hollow tube constitute, and pedestal [2] is in order to connect vertical pivot pipe [1] and front fork [3].Direction base for post shown in Figure 2 [2] and front fork [3] are made by same tubing, and pedestal [2] can be considered sweep, construct simpler.

Describe the structural principle of one of the utility model embodiment ordinary bicycle Bicycle head dormant lock in detail below in conjunction with Fig. 4.In order to illustrate conveniently, the direction post was turned round 90 ° of lockings, can be less than this angle in the practical application.In the present embodiment, the direction post is made of vertical pivot pipe [1] and pedestal [2], vertical pivot pipe [1] and pedestal [2] are hollow structure, and lock body is connected the transmission device of motion by the general lock core of general lock core and this and dead bolt [15] that can expanding-contracting action under this transmission mechanism control is formed.Wherein general lock core is made up of lock core rotor [4], pellet shot from a slingshot [5], pellet shot from a slingshot spring [6] and lock core base [7], and lock core rotor [4] can rotate under key [8] drives, and this general lock core is contained in described direction base for post [2] one end inside, and is fixing by pin [9].Transmission device is by gear rotor [10] and the meshing tooth bar [11] of this gear rotor [10], form with the connecting rod [12] that links to each other with this tooth bar [11], lock core rotor [4] driven gear rotor [10] rotates, tooth bar [11], connecting rod [12] at gear rotor [10] but up-and-down movement under driving, connecting rod [12] upper end is connected with dead bolt [15] through moving axis [13], dead bolt [15] stretch out under the control of dead axle [14] and moving axis [13] or retraction direction post sidewall on breach [16], dead axle [14] is fixed on the matrix [17], matrix [17] is fixed in the vertical pivot pipe [1] by screw [18], during locking, the breach [16] that dead bolt [15] lies across on the direction post sidewall is located with the breach [20] on the vehicle frame steering column cover [19], make the direction post turn round a fixed angle, breach [20] on the vehicle frame steering column cover [19] is positioned at vehicle frame steering column cover [19] and vehicle frame lower oblique tube [21] inside, junction, reaches the purpose that dead bolt [15] does not expose.When unblanking, screw key [8] drives lock core rotor [4] and gear rotor [10] rotates, and tooth bar [11], connecting rod [12] move downward, and in dead bolt [15] the retraction vertical pivot pipe [1], the direction post is free to rotate under pearl frame [22] supports, and headstock release, activity are freely.

Fig. 5, Fig. 6, the basic design philosophy of Bicycle head dormant lock shown in Figure 7 are similar to Fig. 4, lock body has adapted to the inner structure of direction post, and in the vertical pivot pipe [1] of just lock body all being packed into, transmission device slightly changes, with the direction post is the multiple inner structure that housing also can adapt to existing built-in lock, repeats no more.

The utility model Bicycle head dormant lock and direction post are an integral structure, and the effect of competence exertion the utility model Bicycle head dormant lock in the car body of only packing into realizes the purpose of this utility model.Therefore a kind of transportation means that the utility model Bicycle head dormant lock is housed is only the final embodiment of the utility model Bicycle head dormant lock as service orientation post such as bicycle, three-wheel vehicle, motor bike and car that Bicycle head dormant lock is housed.
