Description

Brake hublock tapered end

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, include lock body, lock core, lock pin, be provided with the installation cavity of axial perforation in the described lock body, described lock core is arranged at the side in this installation cavity rotationally, and it is card pivoted housing pipe non-circular and axially each section cross section unanimity that the head end of this lock core is coaxially arranged with the cross section, described lock pin is mounted slidably the opposite side with installation cavity, and this lock pin tail end is coaxially arranged with and blocks the card rotary column that the commentaries on classics of pivoted housing pipe clamp cooperates, this card rotary column is plugged in and constitutes axially interlock in the card pivoted housing pipe, axial slip cooperates, the sidewall of described lock pin is provided with trundle, be provided with the spiral card wall that card is with it joined with respect to the front end of trundle on the described installation cavity, the free end of described lock pin is under the mobile range state at lock pin and stretches out outside the lock body, is provided with back-moving spring between described lock core head end and the lock pin tail end.

The axial inboard fixed cover that described lock pin blocks rotary column relatively further is set spacing ring is housed, the axial inboard that the head end of described lock core blocks the pivoted housing pipe relatively is provided with limited wall, and described back-moving spring two ends are connected to respectively on spacing ring and the limited wall.

Described slippage pipe further is set is outside equipped with the locking closure that mates with lock body.

Advantage of the present utility model is: during locking, rotational lock core, lock pin axially link, axially rely on the elastic force of spring to move forward, thereby the free end of lock pin is reached outside the lock body under being rotatably assorted of lock core, reach locking; During unlatching, the counter-rotation lock core, lock pin is under being rotatably assorted of lock core, axially link, axially rely on the thrust compression spring of spiral card wall, thereby make lock pin be withdrawn in the lock body, reach unlatching trundle, compact conformation, easy to use, and can directly be designed to one, good concealment, good looking appearance with the wheel hub shell.
