Description

Quiet door knob

Technical field the utility model relates to a kind of door knob, especially has the door knob of layer plastics or rubber layer.

The background technology door knob is a kind of door body ancillary service commonly used, is divided into two parts, and a part is made up of groove, magnet, groove fixed support etc., is fixed on the wall bottom; Another part is placed in the bottom of door by bumping ball, bump ball cover, bump the ball spring, bumping ball fixed support etc. and partly form; Two-part correspondence position can be pasted together mutually by magnetive attraction, prevents that door and wall from damaging.But although bump the ball spring, buffering effect is undesirable during its collision, usually flicks again after the collision, and sends the sound, and influence is used.

Chinese patent CN2672239 number disclosed " novel Door stop " patent (application number: CN200420002167.3), form by plug-in unit part and ball formula inserts, plug-in unit partly adopts the design of chair shape, chair shape panel and chair shape supporting surface meet at right angles, chair shape supporting surface surface has screw, and chair shape backrest face has a small embossment; Ball formula inserts then is made up of metal sleeve, spring, steel ball metal base plate.All members all are installed on door-plate inboard and the doorframe, and designed Door stop is simply small and exquisite, both artistic and practical, help making full use of of space behind the door, also make the more comfortable safety in life staying idle at home space simultaneously.The weak point of this patent is: owing to there is magnetive attraction chair shape supporting surface surface is not had screw, chair shape backrest face has a small embossment, and adherence force is very limited; Structure is too complicated, and trouble is installed, and health is swept in inconvenience; And the problem of unresolved " sending collision sound ".In addition, do not retrieve and solve the relevant document of " sending collision sound " problem.

The purpose of this utility model is exactly that a kind of quiet door knob simple in structure will be provided, and when satisfying the normal use of door knob, solves the problem of " sending collision sound ".

The utility model content in order to achieve the above object, the quiet door knob that the utility model provides is except comprising groove, magnet, groove fixed support, bump ball, bumping the part such as ball spring, and also comprise plastics or rubber layer: plastics or rubber layer are wrapped in groove respectively and bump on the surface of ball.When the utility model uses, because plastics or rubber layer are wrapped in groove respectively and bump on the surface of ball, avoided direct collision when bumping ball contact groove, can not send the sound, and have certain cushioning effect.

The quiet door knob that the utility model provides has a significant effect: plastics or rubber layer are wrapped in groove respectively and bump on the surface of ball, and be simple in structure; Avoid direct collision when bumping ball contact groove, can not send the sound, and have certain cushioning effect, solved the problem of " sending collision sound ".

Description of drawings the utility model will be further described in conjunction with the accompanying drawings, please referring to accompanying drawing:
