Description

A kind of noiseless bearing in chair, stool pin body

Technical field

The present invention relates to a kind of noiseless bearing in chair, stool pin body.The effect of its bearing is to allow chair, stool Deng furniture sound is not sent in movement.

Background technology

Have in the development of society, the continuous improvement of living standards of the people, people's quantity rapid growth is lived in building, building indoor Face paving is all big specification floor tile or timber floor, and these furniture of bench can send ear-piercing sound often in movement, and scaring is arrived Indoor and resident family downstairs rest personnel, are attached on furniture leg after having a kind of rubber matting, cutting on the market at present, during dragging Really sound can be eliminated, but is all that body weight is made in this real material because now selling bench, has used and has not had many days rubber mattings to press It is thin, offset, come off, using impermanent.

The content of the invention

In order to change above-mentioned problem, the technical scheme that the present invention solves the use of its technical problem is：1. cartridge housing Body, 1-1. tooth lines, 1-2. tetra- are open, slope in 1-3., 2 spherosomes, 3. springs, and 4. screw key, 4-1. Key jaw type spanners, 4- 2. spoon under keyhole, 4-3., 5. Foot of chair.

It is characterized in that：Bear box (1) is designed with a tooth line (1-1) in upper prop lower cone form, appearance, suitable for reading has four to open Mouthful (1-2), interior slope (1-3), it is internal first from loading spring (3) suitable for reading, be reloaded into spherosome (2), screw the top of key (4) Point it is that Key jaw type spanner (4-1), centre have keyhole (4-2), have lower spoon (4-3) below, is when in use inserted into lower spoon (4-3) Rotated, be installed to after bear box assembling in Foot of chair (5) hole in four openings (1-2).

Operation principle is：Bear box (1) has a tooth line (1-1) in upper prop lower cone form, appearance, such is designed with From the aspect of two, one, lower cone is easy to pierce in the cylindrical hole accomplished fluently in advance and screws；2nd, appearance silk tooth line (1-1) screws in post holes After inwall firmly, the activity of being difficult come off, lower spoon (4-3) be used for insert four opening (1-2) in, play a part of by hand screw, it is interior The effect on slope (1-3) is to prevent spherosome (2) from coming off, and the effect of spring (3) is to withstand spherosome (2), in not outer face pressure Ball is exposed during power, and spheroid is inside contracted when having outer surface pressure, and the effect of spherosome (2) is when Foot of chair (5) is by human bady gravitational Be retracted into pin body and do not work, eject pin body surface face in the presence of spring (3) when losing human body weight, reduce pin body with The contact surface on floor tile surface, so would not occur big sound in artificially dragging chair.

The beneficial effects of the invention are as follows：

1st, this bearing is screwed in using silk tooth line in the drilling of wood, is not loosened, is not fallen off and forever use.

2nd, solve the furniture such as chair, stool, bed in shelter, meeting room, the place such as dining room are noiseless, pollution-free when moving. Its advantage is obvious.
