Description

The multi-functional self-service lock of bicycle

The utility model relates to a kind of locks adapted for bicycle, exactly is the multi-functional self-service lock of a kind of bicycle.

Locks adapted for bicycle all only possesses antitheft effect, function singleness basically at present.If bicycle breaks down in the road that travels or let out, leak gas, and when not carrying relevant repair outfit, it is at a loss what to do then to seem, has to carry out or shoulder away.

The purpose of this utility model is to provide a kind of multi-functional self-service lock of bicycle that can integrate antitheft, repairing, aerification function.

Technical solution of the present utility model is: the multi-functional self-service lock of a kind of bicycle, comprise support, tapered end and locking bar, and its special feature is: support one end is fixed with tapered end, and the other end is fixed with the bearing that the mode cross section has through hole; Locking bar is a tubular cavity, and the termination outer rim of its opening one end is provided with flange, and the other end is solid driver bit, and at the lock nose of the affixed band air cavity of a side of this driver bit, the lock nose can insert in the lockhole of tapered end.

In the described locking bar cavity, be provided with successively and lock gas passage, valve, piston head, piston rod and the gripper shoe that the nose air cavity communicates, extend on the outer connecting rod of locking bar openend and be with spring, the end-face helical connection of its termination and handle.

Be respectively equipped with on the described handle peripheric surface can with the groove of the band corner angle of the commonly used bolt of bicycle, the socket of nut outer rim coupling.

The utility model has the advantages that: an end of the affixed lock nose of locking bar passes from the cross section through hole of bearing, and its lock nose can insert in the lockhole of tapered end, realizes the antitheft effect of the blockade of bicycle; Extract locking bar out and can be used as the screwdriver use, can also use as the inflator inflation; Its handle can also use as spanner, thereby gathers multi-function in integral whole; And novel structure, uniqueness, simple, easy to use can be extensively as bicycle, power assist vehicle, motor Vehicle locks.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the utility model structural representation;

Fig. 2 is the lockhole of tapered end and the bonding state schematic diagram of lock nose;

Fig. 3 is the one side planform schematic diagram of handle peripheric surface;

As seen from Figure 1, it is approximate arc that support 7 is, and its two ends are fixed with bearing 2 and tapered end 8 respectively, have through hole on the cross section of bearing 2.Locking bar 3 is cavity in a tubular form, and the termination outer rim of its opening one end is provided with flange, and the other end is solid driver bit 9.At the lock nose 10 of the affixed band air cavity of a side of this driver bit 9, lock nose 10 can insert (see figure 2) in the lockhole of tapered end 8.

In the cavity of locking bar 3, be provided with successively and lock gas passage 11, valve 5, piston head 4, piston rod 15 and the gripper shoe 16 that nose 10 air cavitys communicate, valve 5 is made of valve seat 5-1, steel ball 5-2 and ventilating cover 5-3, valve seat 5-1 and ventilating cover 5-3 are fixed on the cavity inner wall of locking bar 3, and steel ball 5-2 places between valve seat 5-1 and the ventilating cover 5-3.Piston head 4 is fixed on an end of piston rod 15 by nut 13,14.The other end of piston rod 15 passes the gripper shoe 16 in the port that is fixed on locking bar 3 openings one end, extends in outside opening one end of locking bar 3, is with spring 17 in its termination, and the termination screw thread of having got on the bus can be connected and fixed with handle 1 end face axial internal thread hole 1-1.Also be provided with hook 18 on the one end end face of handle 1 connection piston rod 15, this hook 18 can insert in lock locking bar 3 openends, behind a left side or the dextrorotation handle 1, can make hook 18 by compression spring 17, be connected in the openend of locking bar 3, thereby handle 1 is fixed on the locking bar 3.

The axial car in the other end of handle 1 has screwed hole 1-2, and this screwed hole 1-2 can realize spiral marking connection with the screw thread that the outer rim of the driver bit 9 of locking bar 3 other ends is got on the bus.Be respectively equipped with the groove 1-3 of the band corner angle of the bolt commonly used, the socket of nut outer rim coupling on the peripheric surface of handle 1 with bicycle body.

During use, support 7, bearing 2 and tapered end 8 are fixed on the relevant position of bicycle, will pass with the locking bar 3 of handle 1 through hole again, insert in the lockhole of tapered ends 8, can realize blockade cycle wheel with lock nose 10 from bearing 2 cross sections.As will be to Tyre inflating, available key is opened lock, extract locking bar 3 out, and grasp, the air cavity mouth of lock nose 10 is aimed at the valve inside of tire and push down, hold handle 1 with another, left-handed or dextrorotation breaks away from the openend of locking bars 3 hook 18 on the handle 1, can take out, press piston rod 15, and drive piston head 4 upper and lower activity in locking bar 3, thereby realize aerification function.As want trip bolt, and then locking bar 3 can be extracted out, can make screwdriver and use.As want fastening bolt, nut, and after locking bar 3 is extracted out, screwing off the handle 1 that is connected on piston rod 15 terminations, tune is spun on the outer rim screw thread of driver bit 9, grasps locking bar 3, and the spanner that can make fastening bolt, nut uses.
