Abstract
The utility model discloses a lock for a centre shaft of a bicycle. The utility model is characterized in that the middle part of a centre shaft is made into a square column shape, and a clamping column of which the upper part is controlled by a lock key to move up and down is arranged in the lower end of a front oblique bar or a rear oblique bar of a tripod; a lock core sleeve is fixed on the pipe wall of the oblique bar, and the lower end of the clamping column is provided with a square bayonet corresponding to the square column of the centre shaft. When the lock key rotates towards one direction, the clamping column can move upwards, the bayonet of the clamping column is separated from the centre shaft, so that the centre shaft can freely rotate. When the lock key rotates towards the other direction, the clamping column can move downwards, the bayonet of the clamping column clamps the square column of the centre shaft, so that the centre shaft can not rotate. Therefore, the purpose of locking a bicycle is achieved.
Description
The utility model relates to a kind of lock, especially locks adapted for bicycle.
Present bicycle all is by being fixed on lock or the movable lock on the vehicle frame, passing the spoke of front-wheel or trailing wheel lock is decided.The car front-wheel, the trailing wheel that have are all established lock, have influenced outward appearance U.S. of bicycle, use inconvenience, and owe civilization.
The purpose of this utility model provides a kind of stealth, bicycle lock easy to use.
For achieving the above object, embodiment is: square column type is made at the middle part of the former axis of bicycle, in the steel pipe lower end of the preceding slash of bicycle tripod or back slash, if card post moving up and down, make and the corresponding bayonet socket of axis middle part square column type its lower end, when the card post moved down, bayonet socket can block the square column type of axis, and axis can not be rotated.The top of card post is provided with tooth bar, and tooth bar is provided with gear and its engagement.Lock tube is fixed on the tube wall of slash steel pipe, lock core and gear are fixedly connected, key drives lock core and rotates, gear also rotates, and, drive long column and move up and down: up move, the bayonet socket of card post is separated with the square column of axis by the tooth bar on the meshing with it card post, axis is rotatable, and bicycle can reach steps on row; Move down, the bayonet socket that then blocks post blocks axis, and axis can not rotate, and reaches the purpose of lock car.
The bicycle middle shaft lock of said structure, on the slash steel pipe of spider, only see a key hole, removed the lock of setting up on the former bicycle from, make bicycle seem simple agile, strengthen the aesthetic feeling of bicycle, unlike former bicycle, just can drive or lock car after having found foot rest during use, only need bend over slightly just can drive or lock car, easy to use, civilized.
Below in conjunction with accompanying drawing, further specify of the present utility model.
Fig. 1 is a structural front view of the present utility model.
Fig. 2 is the view that Fig. 1 cuts open along A-A.
Fig. 2 and shown in Figure 1, the preceding slash and the back slash that are bicycle tripod connect with middle shaft device, and the front view of the utility model structure and cutaway view, among the figure, top is divided into semicolumn, and the card post 8 that the bottom is divided into cylinder is arranged in the card column sleeve 5 of tubulose, can move up and down, there are 10 mouthfuls of square bayonet sockets its lower end, and the semicolumn plane on top is provided with tooth bar 7, with quadrant gear 6 engagements.Card column sleeve 5 is fixedly connected with back slash 4.Lock core cover 3 is fixed on behind the bicycle tripod on the slash steel pipe 4 corresponding tube walls, and lock core 2 and quadrant gear 6 in the middle of it are fixedly connected.In the middle of the quadrant gear 6 a key groove is arranged, be used for key 1 and insert rotation.Square column type is made at the middle part of axis 11, and is corresponding with the bayonet socket of card post 8.Also have among the figure: with preceding slash 14 and the trailing wheel bearing support 9 that bottom bracket axle 13 is fixedly connected, the fastener 12 that connects with bottom bracket axle 13 inside threads.
The utility model is work like this: key 1 inserts lock core 2, when key clockwise rotates, then rotates quadrant gear 6, and the tooth bar 7 drive card posts 8 of the card post 8 that is engaged with are up moved, and card post bayonet socket 10 separates with axle 11, and axis is free to rotate; When key 1 rotates counterclockwise, by lock core 2, gear 6 and tooth bar 7, card post 8 is moved down, card post bayonet socket 10 blocks the square column at axis 11 middle parts, and it can not be rotated, and promptly bicycle can not be stepped on row, reaches the purpose of lock car.
Also can be arranged in the preceding slash 14 of bicycle tripod with the structure of locking, effect be located at the back slash the same.No matter be located on any slash,, all are protection domains of the present utility model so long as adopted the lock of this structure.
