So, sliding function, the weight-bearing function of whole auxiliary structure are all achieved, and are not easy to occur horizontal and vertical getting loose.

But door leaf or sash often there will be impact noise in carrying out push-and-pull, for example, between the sound that glass trembles or edge and guide rail ear-piercing metal friction sound, this causes because hand assembled size cannot reach perfect, is difficult to improve. Therefore solution is the first-class quiet adhesive tape of seam crossing at glass and edge mostly at present, or loads onto baffle blanket in the edge of guide rail. And this has exactly ignored one of them important sources of noise, i.e. slide rail wheels. Slide rail wheels are being born the weight of door leaf, and when its slip, inertia is larger, thereby the shake action that is easy to transmit remaining part makes metal joint portion send sound. And if too tight by obtaining on each screw, easily the hiding internal stress of generation causes service life in later stage not long again.

Summary of the invention

The technical problem to be solved in the present invention is: a kind of quiet slide rail wheels are provided, after it installs on door leaf or sash, self are difficult for producing noise when push-and-pull.

The solution that the present invention solves its technical problem is:

A kind of quiet slide rail wheels, comprising: shell, and its entirety is the rectangular box body that Open Side Down, and the first connecting hole is outputed in termination, shell the right, and before and after shell, sidewall is outputed multiple outer bolts hole;

Turning rolls, its entirety is the rectangular box body that Open Side Down, turning rolls inwall is provided with acoustical cotton layer, the front and back width of turning rolls mates with the inside of shell, the second connecting hole is outputed in termination, turning rolls the right, before and after turning rolls, sidewall is outputed the inner bolt hole corresponding with described outer bolt hole, multiple positions, and turning rolls is nested in described shell;

Roller, its quantity is at least two, is arranged on turning rolls by roller bearing;

Traction screw, it longitudinally passes the first connecting hole and the second connecting hole simultaneously and tightens with the pull nut that is positioned at turning rolls;

Transverse bolt, it laterally, simultaneously through outer bolt hole and the inner bolt hole corresponding with this outer bolt hole, links together shell and turning rolls.

As the further improvement of technique scheme, on the body of described traction screw, cover has spring, the two ends of described spring to lean respectively wall and turning rolls outer wall place in the enclosure.

The invention has the beneficial effects as follows: the present invention is provided with acoustical cotton layer at turning rolls inwall, the noise that slide rail wheels produce like this can significantly be decayed, thereby realizes muting function. In addition because acoustical cotton is built-in installation, therefore be difficult for damaged coming off, long service life. The present invention is simple and easy to do, and can be widely used in the assembling of sliding door and window.
