The technical solution of the utility model is specifically described as follows.
The utility model provides a kind of safety theftproof device reequiped based on bicycle middle shaft, and it includes bicycle middle shaft, V
Type vehicle frame, ratchet and pawl；The right side connection chain wheel of bicycle middle shaft, centre position connection ratchet, ratchet is arranged on V frame
Bottom above；Steering wheel and ratchet support are set on V frame, and steering wheel is connected with connecting rod, and connecting rod is to be set on L-type, ratchet support
There is ratchet, ratchet is connected by ratchet rotary shaft with the long side of connecting rod, the short side of connecting rod is extend into below ratchet.
In the utility model, the both sides difference key of bicycle middle shaft connects left crank and right crank, centre position and ratchet
Key is connected.
In the utility model, the angle between ratchet and horizontal plane on ratchet is 4 ~ 8 degree.
In the utility model, the outer surface of the ratchet of ratchet is smooth arc-shaped surface.
In the utility model, annular seal space is also set up, ratchet, steering wheel and connecting rod are installed in annular seal space.
In the utility model, annular seal space is made up of the closure of the cavity in V types and inverted trapezoidal lid.
Compared to the prior art, the beneficial effects of the utility model are：
Device of the present utility model can realize bicycle automatic unlocking, time-saving purpose of locking；Again because voluntarily
Bicycle is had no effect on while car is locked continue to move ahead in itself because of inertia, therefore can the more sound assurance peace ridden
Entirely.

Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Embodiment 1
Referring to shown in Fig. 1-Fig. 6, the safety theftproof device in the present embodiment, including bicycle middle shaft 10, V frame 40,
Ratchet 20 and ratchet 30；The centre position setting rectangular spline 12 of bicycle middle shaft 10, the centrally disposed internal spline 21 of ratchet 20,
Ratchet 20 is processed into by No. 45 Fine Steel Casting irons, and the angle of ratchet 22 and horizontal plane on ratchet 20 is 5o；Bicycle middle shaft
10 are fitted close installation ratchet 20 by rectangular spline 12 and internal spline 21；Ratchet 20 is arranged on above the bottom of V frame 40,
The both sides of bicycle middle shaft 10 set external splines 11 respectively, the internal spline phase interworking with being arranged on right crank 80 and left crank 90
Close；Bearing 60 is divided equally to be used to bear axis radial load in the both sides of bicycle middle shaft 10；Chain wheel 50 passes through weldering with right crank 80
Binding is integrated, and is processed by grey cast-iron casting；Two pedals 100 are connected with right crank 80 with left crank 90 by nut 70
Connect.
Steering wheel 110 and ratchet support 41 are set, and steering wheel 110 is connected with connecting rod 120, connecting rod 120 is L-type on V frame 40,
Ratchet support 41 is provided with ratchet 30, and ratchet 30 is connected by ratchet rotary shaft 130 with the long side of connecting rod 120, ratchet rotary shaft
130 mainly play fixation, are connected with ratchet 30 in the way of latch, and the short side of connecting rod 120 extend into the lower section of ratchet 30.Ratchet
30 are processed into by 40CR steel.Connecting rod 120 manipulates smooth arc-shaped surface 31 of the active position of ratchet 30 below ratchet 30, smooth mesh
Be more smooth in order to be acted in control process.
Steering wheel 110, ratchet 30 and connecting rod 120 are outer to set closed chamber, and annular seal space is to be total to by V-arrangement cavity 140 with closure 150
With constituting, its role is to protection device not by extraneous factor（Including collision sleet etc.）Hinder and damage.
When being switched using safety theftproof device of the present utility model, steering wheel 110 is raised ratchet 30 by connecting rod 120
30 ° ~ 40 ° of angle, and realize that normally opened and bicycle can run well by the auto-lock function of steering wheel 110, closed mode is
Steering wheel 110 is resetted, and ratchet 30 is declined by the gravity of itself, so as to pin ratchet 20, now bicycle can not run well.I.e.
Bicycle normal forward can not be driven by chain-driving flywheel, has reached that automatic is the purpose of bike locking.By this
Mode can not only realize bicycle automatic unlocking, time-saving purpose of locking, and because while bike locking simultaneously
The bicycle is not influenceed to continue to move ahead in itself because of inertia, so that the more sound assurance safety ridden.
