Description
Technical field
The utility model relates to a kind of lockset, specifically is meant a kind of brake hublock tapered end.
Background technology
Light two-shipper motor-car such as light motorcycle and electric bicycle is subjected to the welcome of town and country citizen and wage-earners day by day owing to light, inexpensive, has therefore obtained great development in recent years, and the market occupancy volume significantly improves.The antitheft means of existing various motorcycle or electric motor car are to rely on the head lock of car body ignition switch one or with common steel cable lock mostly, chain lock, U-shaped locks etc. are as electronic lock, front-wheel or trailing wheel by the locking electric motor car come antitheft, but, head lock is often easily caused lockout failure by lawless person's line disconnection, theftproof performance is more limited, and use common U-shape lock, chain lock, steel cable lock is owing to be not the annex of car body own, the disguised end, easily opened by lawless person's violence, and U-shape lock, chain lock, it is also not attractive in appearance that steel cable lock is locked on the car body profile, also loses easily.
The utility model content
The objective of the invention is in order to overcome the shortcoming and defect of prior art, and a kind of and motorcycle or electric bicycle brake wheel hub one, good concealment, brake hublock tapered end easy to use are provided.
For achieving the above object, the technical solution of the utility model is, comprise lock body, lock core, the slippage pipe, lock pin, be provided with the installation cavity of axial perforation in the described lock body, described lock core rotatably is arranged at the tail end of this installation cavity, the head end of described lock core is provided with rotating fulcrum, described rotating fulcrum sidewall is provided with the helical trip, described slippage pipe is mounted slidably in installation cavity, and its lateral wall is provided with the radial location projection, the position of relative this radial location projection of described installation cavity is provided with radially blocks the axial slip rail of joining with it, the tail end of described slippage pipe is set on the described rotating fulcrum, and the tail end sidewall of this slippage pipe is provided with the helical bayonet socket that cooperates with the clamping of helical trip, described lock pin is mounted slidably in the head end of slippage pipe, and the free end of this lock pin is under the mobile range state at lock pin and stretches out outside the lock body, the head end of the tail end of described lock pin and slippage pipe is provided with the locating part that mutual card is joined, be provided with the coil tension spring that two ends are resisted against lock pin tail end and rotating fulcrum head end respectively in the described slippage pipe, be provided with back-moving spring between described slippage pipe and the installation cavity.
It is that two ends are connected to the compression spring on slippage tube head end end face and the installation cavity head end inner face respectively that described back-moving spring further is set.
Further being provided with is that described lock pin is set in the slippage pipe slidably, and the free end of this lock pin exposes outside the slippage pipe, the described annular lip of locating part that is arranged at the lock pin tail end for being provided with towards slippage inner tubal wall direction, the annular lip that the described locating part that is arranged at the head end of slippage pipe is provided with for direction in the slippage pipe.
Further be provided with is that described slippage pipe is outside equipped with the locking closure that mates with lock body.
Further be provided with is that described lock pin tail end is provided with the cavity with the coil tension spring scarf.
Advantage of the present utility model is: rotate towards a direction by lock core, driving the slippage pipe moves, make lock pin break away from the restriction of slippage pipe locating part, and under the effect of coil tension spring, stretch out lock body, thereby pinning wheel hub, and lock core is when rotating in the opposite direction, and lock core has lost the thrust to the slippage pipe, and slippage this moment pipe resets under the effect of back-moving spring, because lock pin slippage pipe is provided with the locating part that mutual card is joined, so slippage pipe reset strap pendulum lock pin resets, and lock pin is withdrawn in the lock body, thereby has decontroled the locking to wheel hub, compact conformation, easy to use, and can directly be designed to one, good concealment, good looking appearance with the wheel hub shell.
