Description

A kind of lock uses knob

Technical field

The present invention relates to lockset knob technical field, specially a kind of lock uses knob.

Background technique

In the modern times, the pattern of door lock is many kinds of, so that requirement of the people to door lock is also higher and higher, the safety of door lock Be with reliability it is most important, certainly, aesthetics is also indispensable, and mechanical lock can be described as the evergreen tree in door lock, not only Easy to operate and practical, knob assembly is exactly a kind of mechanical lock that comparison is economical, and knob is the important set of knob assembly Part affects the sensitivity of knob assembly, accuracy and aesthetics.

And conventional knob is by zinc casting forming, cast(ing) surface has die casting print, has crackle or local deformation, there is gas Hole, shrinkage cavity, casting structure will appear scarce material, and fillet is unknown, be not sufficiently stable, and after the forming of knob blank, also throw by machining Light greatly increases cost and manufacturing cycle, and these problems are accumulated over a long period, and finally will affect the sensitivity of knob assembly, accuracy And aesthetics, for this purpose, it is proposed that a kind of lock uses knob.

Summary of the invention

The purpose of the present invention is to provide a kind of lock knobs, to solve conventional knob mentioned above in the background art It is by zinc casting forming, cast(ing) surface has die casting print, has crackle or local deformation, there is stomata, shrinkage cavity, casting structure will appear Material is lacked, fillet is unknown, is not sufficiently stable, and after the forming of knob blank, also to greatly increase cost and manufacture by machining, polishing The problem of period, these problems are accumulated over a long period, and finally will affect the sensitivity of knob assembly, accuracy and aesthetics.

To achieve the above object, the invention provides the following technical scheme: a kind of lock knob, including knob body and shell Body, the both side surface up and down of the knob body is respectively and fixedly provided with bed course, and the left side wall of knob body is provided with bolt, described to insert Circlip is installed on the outside of pin, and is provided with torsionspring on the left of bolt, fixing seat is installed on the outside of the torsionspring, The right end face of the shell is provided with guard ring, and shell is located at the outside of fixing seat, pacifies around the surface of the guard ring Equipped with illumination lamp bead, it is provided with back seat plate on the left of the shell, and elastic shrinkage circle is installed between back seat plate and shell, institute It states and is fixed with control-rod on the left of back seat plate, and pressure spring is installed on the outside of control-rod.

Preferably, the horizontal center line between the bed course about knob body is symmetrical, and the upper and lower surface of knob body Inwardly it is recessed in arc-shaped.

Preferably, it is parallel to each other between the circlip and torsionspring, and pair of the symmetrical center line of circlip, torsionspring Claim to overlap between center line and the horizontal center line three of knob body.

Preferably, the illumination lamp bead is annularly uniformly arranged on the outer surface of guard ring, and the medial surface of guard ring with It is fitted closely between the right end face of shell.

Preferably, the back seat plate constitutes elastic extension structure, and shell and fixing seat by elastic shrinkage circle and shell Between to be fixedly connected.

Preferably, the pressure spring is uniformly arranged on the outside of control-rod in the shape of a spiral, and the outer wall of control-rod and pressure spring It is bonded to each other between medial surface.

Compared with prior art, the beneficial effects of the present invention are: lock knob passes through professional mold, by lock knob Injection molded of shape and internal structure is not necessarily to secondary operation, is directly electroplated, that is, can be used, and replaces zinc by using plastics Alloy die cast handle external disk, it is the advantages of not only avoiding the defect of zinc alloy diecasting generation, and given full play to plastics, i.e., firm Solid, anticorrosive, waterproof and the processing is simple, the structure setting of knob body, facilitate the assurance of people and have an effect, bed course is for protecting The outer surface of knob body has antiwear protective effect to knob body, and circlip and torsionspring are arranged in knob Portion is unified into elastic force room structure, guarantees the firm stabilization of entire knob structure, rotation flexibly, and can Rapid reset, headlamp The setting of pearl, is the position for the ease of quickly determining knob in dark, on the one hand guard ring plays mounting arrangements illumination lamp bead Effect, on the one hand then the end face of shell is protected, connected between back seat plate and shell by elastic shrinkage circle, in elasticity Under the action of shrink-ring, between back seat plate and shell when being squeezed active force, can accordingly it shrink, elastic shrinkage circle is to the two Between movement play the role of buffering transition, shell and fixing seat constitute the cover body structure of entire knob, can once be molded Forming, greatly facilitates production, and the setting of pressure spring has one when for guaranteeing that the components such as control-rod and door body or door lock are connect Locate elastic force pressure texture, facilitates the installation of knob, while should mutually can also protect to knob by elastic force.
