Abstract

The utility model discloses a self-locking mechanism of a handle element of a horseshoe-shaped lock, which comprises a handle element connected with a lock beam in a lock casing arc-shaped groove. The handle element comprises a rivet connected with the lock beam, a handle body capable of moving vertically along the rivet is sleeved on the rivet, the width of the end of the locking casing arc-shaped groove is larger than the diameter of the end of the handle body, the widths of other parts of the lock casing arc-shaped groove are smaller than the diameter of the end of the handle body, a spring is sleeved on the rivet, a gasket and a spring retaining ring are sequentially arranged above the spring, and the spring retaining ring is clamped in a conical groove on the upper portion of the rivet. The self-locking mechanism is reasonable in structure. The handle has a function of self locking.

Description

The self-locking mechanism of u-shaped lock handle shank spare

Technical field

The utility model relates to a kind of self-locking mechanism of u-shaped lock handle shank spare.

Background technology

The bicycle u-shaped lock is mainly constructed by lock housing parts (die casting or stamping parts), lock core parts, lock bridge parts, handle shank spare, spring members, limit clamp assembly etc. and is formed.When this lock is installed, be the limit clamp assembly to be fixed on the tripod breeches pipe of bicycle with screw.When executing lock, handle shank spare drives the lock bridge parts and rotates under external force.When the lock bridge parts arrive the relevant position, can automatically reset under the spring action of plectrum in the lock core parts in the lock core parts, block the groove on the lock bridge parts, the lock bridge parts can not be rotated by return, the lock bridge external part blocks the wheel steel wire, thereby wheel can't rotate.When unblanking, the key in the rotational lock core parts drives lock core and rotates, and plectrum leaves groove, and lock bridge parts return under the effect of spring members rotates, thereby in the external part of the lock bridge withdrawal lock housing, wheel is accessible.General u-shaped lock all adopts such handle shank spare structure, it is simple in structure, be convenient to make and assembling, but they have a shortcoming: bicycle in the process of moving, forbid touching handle shank spare, otherwise might drive the handle handle, lock bridge is rotated, in case the lock bridge external part is run into steel wire, will meet accident.In safety, exist hidden danger.

Summary of the invention

It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and the handle handle has the self-locking mechanism of the u-shaped lock handle shank spare of auto-lock function.

Technical solution of the present utility model is:

A kind of self-locking mechanism of u-shaped lock handle shank spare, comprise the handle shank spare that is connected with lock bridge in the lock housing deep-slotted chip breaker, it is characterized in that: handle shank spare comprises the rivet that is connected with lock bridge, the handle handle body that suit can move up and down along rivet on the rivet, the width of lock housing deep-slotted chip breaker end is greater than the diameter of handle handle body tip, the width at other positions of lock housing deep-slotted chip breaker is less than the diameter of handle handle body tip, pocketed springs on the rivet, the spring top sets gradually packing ring and check ring, and check ring is stuck in the rivet upper taper groove.

The utility model is rational in infrastructure, does not change horseshoe-shaped essential structure, and by the part change to several component, the integrated part with the handle handle is designed to combined part simultaneously.Unique internal construction is rotated handle shank spare, and an action of carrying on gently must be arranged, and the back handle handle that puts in place could rotate.Otherwise the handle handle can not rotate.Bicycle does not worry that the handle handle is run into unintentionally when carrying out or riding like this, error-locking takes place and produces accident.Be similar to manual-gear vehicle when hanging reverse gear, control stick needs an additional move (as pressing down), just can hang up retaining.The self-locking mechanism design of this handle shank spare is to bicycle u-shaped lock, good market prospects.

Description of drawings

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

Fig. 1 is the structural representation of an embodiment of the utility model.

Fig. 2 is to use u-shaped lock structural representation of the present utility model.

The specific embodiment

A kind of self-locking mechanism of u-shaped lock handle shank spare, comprise the handle shank spare that is connected with lock bridge 2 in the lock housing deep-slotted chip breaker 1, handle shank spare comprises the rivet 3 that is connected with lock bridge, the handle handle body 4 that suit can move up and down along rivet on the rivet, the width of lock housing deep-slotted chip breaker end 5 is greater than the diameter of handle handle body tip, the width at other positions of lock housing deep-slotted chip breaker is less than the diameter of handle handle body tip, pocketed springs 6 on the rivet, the spring top sets gradually packing ring 7 and check ring 8, and check ring is stuck in the rivet upper taper groove.Hold handle cover 9 among the figure in addition.

Claims

1. the self-locking mechanism of a u-shaped lock handle shank spare, comprise the handle shank spare that is connected with lock bridge in the lock housing deep-slotted chip breaker, it is characterized in that: handle shank spare comprises the rivet that is connected with lock bridge, the handle handle body that suit can move up and down along rivet on the rivet, the width of lock housing deep-slotted chip breaker end is greater than the diameter of handle handle body tip, the width at other positions of lock housing deep-slotted chip breaker is less than the diameter of handle handle body tip, pocketed springs on the rivet, the spring top sets gradually packing ring and check ring, and check ring is stuck in the rivet upper taper groove.
