Description
Technical field the utility model relates to a kind of door knob, especially has the door knob of buffer structure.
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, 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.
The purpose of this utility model is exactly that a kind of buffer-type door knob simple in structure, easy to use will be provided, and when satisfying the normal use of door knob, improves buffering effect.
The utility model content in order to achieve the above object, the buffer-type door knob that the utility model provides is except comprising groove, magnet, bump ball, bumping the part such as ball spring, also comprise buffer structure: buffer structure is made up of buffer spring, travel(l)ing rest, fixed support, air vent, wherein, groove is positioned on the travel(l)ing rest; Fixed support is cylindric, and travel(l)ing rest inserts in the fixed support, and buffer spring connects travel(l)ing rest and fixed support; Air vent is positioned on the fixed support.When the utility model uses, bump ball contact groove, travel(l)ing rest moves in fixed support, and the compression buffer spring discharges impact force, and the air in the fixed support is discharged by air vent.
The buffer-type door knob that the utility model provides has a significant effect: buffer structure is made up of buffer spring, travel(l)ing rest, fixed support, air vent, and is simple in structure; Buffer spring, travel(l)ing rest, fixed support and air vent are also formed an air spring structure based on the fixed support inner chamber, with buffer spring, bump the ball spring, constitute the combined type buffer system, improve the door knob buffering effect greatly, use very convenient.
Description of drawings the utility model will be further described in conjunction with the accompanying drawings, please referring to accompanying drawing:
Accompanying drawing is represented schematic diagram of the present utility model.
Structure shown in the drawings comprises: groove (1), travel(l)ing rest (2), fixed support (3), air vent (4), buffer spring (5).
The buffer-type door knob that specific embodiment the utility model provides is except comprising groove (1), magnet, bump ball, bumping the part such as ball spring, also comprise buffer structure: buffer structure is made up of buffer spring (5), travel(l)ing rest (2), fixed support (3), air vent (4), wherein, groove (1) is positioned on the travel(l)ing rest (2); Fixed support (3) is cylindric, and travel(l)ing rest (2) inserts in the fixed support (3), and buffer spring (5) connects travel(l)ing rest (2) and fixed support (3); Air vent (4) is positioned on the fixed support (3).When the utility model uses, bump ball contact groove (1), travel(l)ing rest (2) moves in fixed support (3), and compression buffer spring (5) discharges impact force, and the air in the fixed support (3) is discharged by air vent (4).
The utility model protection domain relates to all changes form recited above.
