When the lock tongue and the lock hole are facing, the lock tongue is inserted into the lock hole for locking purpose. The unlocking handle is connecting to the pull line whose one end is located at the site easy to operate. The utility model is characterized in fastening locking and high security; the process of locking saves strength and easily to operate.

Description

Vehicle frame blocking device before and after the folding bicycle

(1) technical field

The utility model relates to the folding bicycle field, is specially a kind of folding bicycle front and back vehicle frame blocking device.

(2) technical background

Vehicle frame must be fixing after vehicle frame launches before and after it to folded structure before and after folding bicycle mostly was at present, could guarantee the monolithic stability of vehicle frame, and riding safety is comfortable.

The blocking device folding and that launch of vehicle frame mainly adopts inserting bolt type or eccentricity pressure handle two class modes before and after the folding bicycle at present.Plug and keyhole are bearing fit in the blocking device of inserting bolt type, certain interval is originally arranged between the two, plug is used component wear, vibrations in the bicycle running process also cause wearing and tearing, the tolerance clearance of plug and keyhole is strengthened, the vehicle frame connection stability reduces before and after causing, and influences the safety of vehicle '.In the lockout mechanism of eccentricity pressure handle type, the eccentricity pressure bar enters the open slot of lock body one side when closed, stirs the handle pressurization and makes it to remain closed.Because its eccentric angle is that eccentricity pressure is artificial adjusting control, in case control improperly, the vibrations in the process of riding might cause lock body loosening, even press rods can be deviate from consequence danger along open slot.Except the problem of potential safety hazard, the operation of above-mentioned blocking device is also inconvenient, and the user need bend to move plug or dial the commentaries on classics eccentric handle at the conversion vehicle-state.

(3) utility model content

The purpose of this utility model is a vehicle frame blocking device before and after a kind of folding bicycle of design, has two-way lock pin and inserts lockhole, and spring force guarantees locking, vehicle frame tight closure before and after making.

The vehicle frame blocking device comprises the lock body that is installed in vehicle frame abutting end behind the folding bicycle before and after the folding bicycle of the present utility model, be installed in the locking closure of front vehicle frame abutting end, locking closure is hinged with the hinge that is installed in the back vehicle frame, lock body is a housing, the axle of unblanking of lock body internal fixation is gone up the gear of unblanking is installed, the dead bolt of two cylindricality lock pins respectively up and down up and down, lock pin is connected with an end of last lower spring respectively up and down, the other end of last lower spring is fixed in the housing of lock body, the affixed upper rack in the below of last lock pin, the affixed tooth bar down in the top of following lock pin, tooth bar is engaged with at the left and right sides of the gear of unblanking respectively up and down.An outer end of unblanking is equipped with unlocking handle.Locking closure has parallel upper and lower covers, and the front end of upper and lower covers is mutually permanently connected, and hinged with affixed rear end of front vehicle frame and hinge.The lockhole that matches with the dead bolt on lock pin top is arranged on the upper and lower covers, and when locking closure turns to its upper and lower covers when being positioned at the lock body upper and lower, dead bolt inserts in the lockhole.

Rotate unlocking handle, the gear of unblanking rotates thereupon, and the tooth bar up and down that is engaged with moves to upper and lower synchronously, lock pin moves down in the drive, lock pin moves synchronously down, dead bolt is deviate from the lockhole of locking closure synchronously up and down, unlocks, and front vehicle frame can be transferred folding to 180 degree backward.When needing to launch, front vehicle frame is rotated return forward, when the upper and lower covers of locking closure is got back to the lock body upper and lower, dead bolt enters in the lock body compressing of upper and lower covers forward position up and down, upward lower spring is compressed, when lockhole is relative with dead bolt, under the spring tension effect, dead bolt inserts in the lockhole, and keeps lock-out state under action of the spring.

Level and smooth for combining of locking closure and lock body moved, be angular plane surface or oblique cambered surface in the face of locking closure moves into direction dead bolt one side, the upper and lower covers of locking closure has the arcuate guide edge that upwarps of matching with dead bolt towards the side edge of lock body.When the upper and lower covers of locking closure turned to the upper and lower of lock body, the arcuate guide of its upper and lower covers was pressed into lock pin in the lock body along being pressed on the Dou face of dead bolt gradually smooth-goingly.

One end of unlocking handle cylinder lever connecting rod or backguy, the other end of pull bar or backguy is connected with bar handle on being fixed in vehicle seat or handlebar or vehicle frame.The unlocking handle of needn't bending to rotate when unblanking only needs to use a bar handle that is positioned on vehicle seat or handlebar or the vehicle frame to get final product.

The advantage of vehicle frame blocking device is before and after the utility model folding bicycle: 1, the lock pin up and down of lock body inserts in the upper and lower covers of locking closure, spring makes it secure lock, vehicle frame did not remain in best tightening state before and after vibrations during vehicle is ridden did not also influence, and fully guaranteed safety when vehicle is ridden and stable; 2, the cooperation of the Dou face of the arcuate guide edge of locking closure upper and lower covers and dead bolt makes locking process smoothly laborsaving; 3, being fixed in the bar handle that makes things convenient for the position on the car can unblank by pull bar or backguy manipulation, easy to operate; 4, simple in structure, parts are not easy to wear, long service life.
