Description

The built-in anti-theft lock for bicycle of handlebar vertical rod

The utility model relates to the bicycle lock tool, and concrete is the built-in anti-theft lock for bicycle of a kind of handlebar vertical rod.

Bicycle is that China city, the village people people use maximum vehicle, because it is light, do not consume energy that the source is easy to use, price is low, because of tail gas and noise contaminated environment, road pavement is less demanding unlike automobile, thereby development does not wane so far.Need lock during bicycle storing with anti-lost, existing bicycle lock has various types, but their common ground is bicycle lock and bicycle is split, what have during use is contained on the bicycle with the screw clamping plate, what have is chain and the each dismounting of need, exist and use inconvenience, easily by defectives such as the robber pry open.

The purpose of this utility model provides the built-in anti-theft lock for bicycle of a kind of handlebar vertical rod, and its lock body is welded on the cycle frame front sleeve, the locked groove in the flexible handlebar vertical rod of coming in and going out of its built-in dead bolt and handlebar can not be rotated, simple in structure, easy to use, antitheft, pick-proof, insurance, safety.

The purpose of this utility model is achieved in that

The built-in anti-theft lock for bicycle of a kind of handlebar vertical rod comprises that housing, dead bolt, lock core, lock core are the gauge member that overhanging eccentric shifting block is arranged, and it is characterized in that:

Housing is the obturator that the rectangle slotted eye is arranged, and in its rectangle slotted eye dead bolt is housed, and this rectangular channel front end open-mouth is welded in the cycle frame sleeve pipe, is shaped on this vehicle frame sleeve pipe to hold the flexible gap of dead bolt; Above housing, there is transverse holes to be communicated with the rectangle hole slot, the lock core of gauge member is housed in this transverse holes;

Dead bolt is the rectangular cuboid of cross-sectional plane, its front end has the plate-shaped plate, there is cross sections the position that aligns the housing transverse holes at the middle part of dead bolt, the width of this otch is corresponding with the eccentric shifting block of mark lock pin, there is dress compression spring in the circular hole its rear end, and this spring end contacts in the bottom of housing rectangle slotted eye;

On the handlebar vertical shaft in being loaded on the vehicle frame sleeve pipe, holding the flexible gap equal-height position of dead bolt with sleeve pipe, be shaped on some axial sockets, the ligulate plate of its size and dead bolt front end is corresponding, when dead bolt was stirred because of the eccentric shifting block of lock core and moved forward by action of the spring, this ligulate plate inserted the jack in handlebar vertical rod and limits the rotation of handlebar.

The plate end face of described dead bolt front end is shaped on chamfering.

Inboard and its superjacent air space that described housing is welded in the close vehicle frame of vehicle frame anterior cannula can hold the appropriate location that lock core key is extracted.

The utility model has following actively useful effect:

1. lock body and bicycle are conjoined structure, have been welded in when bicycle dispatches from the factory on the vehicle frame front sleeve, and be solid firm, easy to use.

Dead bolt hide in lock body, flexible unlatching and the locking that enters the slot in the handlebar vertical rod and realize locking of the place ahead plate of dead bolt, no exposed parts, and the locking rear bar can not extract, thereby antitheft, pick-proof insure, safety.

3. use the key operated standardized lock core (market is on sale) of criss-cross, four row's pellets shot from a slingshot of criss-cross installing are arranged in the lock core, can prevent that the robber from using master key to unblank.

4. easy to use, be active in one's movements.

5. simple in structure, volume is small and exquisite, is easy to promote.

Now in conjunction with the accompanying drawings with preferred embodiment:

Fig. 1 is the bicycle profile scheme drawing that the utility model lockset is housed;

Fig. 2 is the structural representation of the utility model lockset;

Fig. 3 is the A-A parting view of Fig. 2;

Fig. 4 is the B-B parting view of Fig. 2, shows latched position;

The same Fig. 4 of Fig. 5 shows the open position.

Accompanying drawing number:

1. housing 101. rectangle slotted eyes 102. are adorned the transverse holes of lock cores

103. front end is uncovered

2. dead bolt 201. front end ligulate plates

202. hold the cross sections 203. spring-loaded tail end circular holes of lock core shifting block

3. spring

4. lock core (gauge member)

401. eccentric shifting block 402. keys that stretch out the lock core lower end

5. cycle frame anterior cannula 501. is held the flexible gap of dead bolt

6. the socket (several are arranged) in bicycle handle bar's vertical rod 601. vertical rods

The built-in anti-theft lock for bicycle of the utility model handlebar vertical rod comprises that housing 1, dead bolt 2, lock core 3, lock core are the gauge member that overhanging eccentric shifting block is arranged, and please refer to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5.

Housing 1 is equipped with dead bolt 2 for the obturator of rectangle slotted eye is arranged in its rectangle slotted eye 101, uncovered 103 places of this rectangular channel front end are welded in cycle frame sleeve pipe 5, is shaped on this vehicle frame sleeve pipe to hold the flexible gap 501 of dead bolt; Above housing, there is transverse holes 102 to be communicated with rectangle hole slot 101, the lock core 4 of gauge member is housed in this transverse holes 102;

Dead bolt 2 is the rectangular cuboid of cross-sectional plane, its front end has plate-shaped plate 201, there is cross sections 202 position that aligns the housing transverse holes at the middle part of dead bolt, the width of this otch 202 is corresponding with the eccentric shifting block 401 of mark lock pin 4, there is dress compression spring 3 in the circular hole 203 its rear end, and these spring 3 ends contact in the bottom of housing rectangle slotted eye 101;
