Description

From the hoop lock

The utility model is a kind of for motor vehicle hoop certainly of various wushu lock that is applicable to.

Wushu lock is in the past installed trouble, and needs special tool, theftproof performance also undesirable.

The purpose of this utility model provides the certainly hoop lock of a kind of carbon steel through heat treated tool-type, cutter formula, and this lock is easy for installation, and theftproof performance is strong.

The purpose of utility model realizes by following manner:

From hoop lock a pipe collar (1) is arranged, have in the pipe collar and be used for the internal thread (2) that the pipe box screw thread is used before the vehicle frame, bit-withdrawing slot (3) has the plate bar hole (4) of two symmetries on the pipe collar external diameter, and the lock body (5) with the pipe collar one is provided with lock pin (6); The lock pin front end is to be used for boring saturating preceding tube wall, the front fork wall, the drill bit of tube wall (7), have annular tooth (8) on the lock pin, have the cross recess that rotates for instrument on the lock pin rear end face, the rear portion is closing compression helical spring (9), end socket (10) also is provided with pin tumbler lock body in the lock body, lock cylinder assembly (11), have on the rotating lock core cylindrical and the corresponding gear of lock pin annular tooth (12), also have through hole (13) on the lock pin.

Below in conjunction with accompanying drawing the utility model is described in detail:

Accompanying drawing is from binding round the lock construction schematic diagram.

As shown in drawings: the hoop lock has a pipe collar (1) certainly, have in the pipe collar and be used for the internal thread (2) that the preceding pipe box screw thread of vehicle frame is used, bit-withdrawing slot (3), what have two symmetries on the pipe collar external diameter pulls thick stick hole (4), be provided with lock pin (6) with the lock body (5) of pipe collar one, the lock pin front end is to be used for boring saturating preceding tube wall, the front fork wall, the drill bit of tube wall (7), have annular tooth (8) on the lock pin, have the cross recess that rotates for instrument on the lock pin rear end face, the rear portion is closing compression helical spring (9), end socket (10), also be provided with pin tumbler lock body in the lock body, lock cylinder assembly (11) has on the rotating lock core cylindrical and the corresponding gear of lock pin annular tooth (12), also has through hole (13) on the lock pin.Install when the hoop lock, handlebar is unloaded, pipe collar is enclosed within on the preceding standpipe head, pulling thick stick with two extend into and pulls in the thick stick hole back and rotate and pull thick stick, under the condition of pipe collar standpipe before internal thread acts on, equally will reduce to the position of your required peace with the bolt die mantle fiber, also produce and the corresponding to external screw thread of pipe collar internal thread through the cutting of pipe collar internal thread on the standpipe before this moment from the hoop lock.Afterwards handlebar is installed, go to required locking angle, aim at lock pin outer face cross recess with special tool, the clockwise direction that does not stop holds out against rotation, can bore preceding standpipe wall, front fork tube wall, handlebar wall saturating.After boring well, closing compression helical spring is loaded onto, end socket is sealed, and the hoop lock has promptly installed certainly, and be in blocking from binding round lock this moment, and with the key rotation lock core that matches, lock core gear drives the lock pin annular tooth, and lock pin withdraws from from handlebar tube, vertical tube of front fork, and handlebar can rotate; During locking, only need handlebar is gone to the locking angle, lock pin enters in vertical tube of front fork and the handlebar tube under the closing compression helical spring effect automatically, the cylinder lock gear rotates when stopping under the effect of lock pin annular tooth, the shank pellet shot from a slingshot enters lock core marble hole under the effect of pellet shot from a slingshot spring, the hoop lock is by locking certainly, and it is motionless that handlebar changes.

Any in the past pin tumbler lock body before the hoop lock can adopt, the lock cylinder structural principle, be used for locking after becoming tooth on the lock core cylindrical by the technical requirements of binding round lock certainly from hoop, closing compression helical spring (9), end socket (10) is removed need not, lock pin (6) rear portion polished rod portion lengthening exposes lock body (5), and during locking, directly hand is pressed lock pin (6), rotate the handlebar locking, can become a kind of new hand push type from the hoop lock; Every binding round the key that lock all is fixed with coupling certainly.

Drill bit (7) is that two bodies connect together with lock pin (6), and there is through hole (13) centre, after being used to drill through drill bit is hit down in the front fork tube; For preventing hand push type hoop lock lock pin (6) certainly, come off, lock body (5) is provided with and corresponding interior step of lock pin (6) outer end step and interstage sleeve; For preventing lock pin (6), front fork tube is caused wearing and tearing, aim at front fork tube and be furnished with corresponding wear-resistant sleeve.

Claims (2)
