Description

Rail ball bushing cushioning shock absorber structure

The invention relates to a technical field of a buffer suspension and sound attenuating structure of an inner slide rail, a middle slide rail and an outer slide rail, wherein the middle slide rail and the first iron bead bushing.

Press, the three-slide rail set by the inner slide rail 7 (with reference to FIG. 1, FIG. 2), the middle slide rail 8 and the outer slide rail 9 is used, and the drawer (not shown) together with the inner slide is used during use. When the rail 7 is closed rearward, it is easy to generate noise due to the rear end 701 of the first iron ball bushing 70 easily hitting the stoppers 81 and 82 behind the middle rail 8, and the first iron is easily caused even when used for a long time. The bead bushing is deformed to affect the smoothness of the sliding.

In view of the lack of the aforementioned conventional products, the inventors have finally developed a kind of rail-mounted iron bead bushing buffer suspension and sound reduction structure through continuous research and testing.

The main object of the present invention is to provide an iron ball bushing cushioning shock absorbing structure for a slide rail, wherein the buffer member provided by the middle rail has a shock absorbing effect when absorbing the first iron ball bushing to absorb the impact force and reduce noise.

A second object of the present invention is to provide an iron ball bushing cushioning shock absorbing structure for a slide rail, which is formed after the front side of the body portion is impacted by the end edge of the lower wall surface of the first ball bushing. The rear edge of the side wall surface of the left and right sides of the first iron bead bushing can be further blocked by the side stops of the left and right sides of the body portion to further enhance the cushioning and shock absorbing effect, thereby achieving more comprehensive blocking and Buffer suspension and sound reduction effects.

A further object of the present invention is to provide an iron bead bushing for a slide rail The shock absorber structure is used for long-term use to avoid deformation of the first iron bead bushing, thereby ensuring smooth sliding.

The utility model relates to a rail ball bushing cushioning shock absorbing structure, which comprises at least an inner sliding rail, a middle sliding rail, a first iron bead bushing, an outer sliding rail and a second iron bead bushing, and the characteristics thereof Wherein: a rear side of the bottom surface of the middle rail is fixedly disposed to provide a cushioning member for forming a cushioning shock when impacted by the rear end edge of the first iron ball bushing to absorb the impact force and reduce noise, and when the body portion is After the front side is impact-deformed by the rear edge of the lower wall surface of the first iron bead bushing, the rear edge of the left and right side wall surfaces of the first iron bead bushing can be further divided by the body part left and right. The side stops connected to the side are blocked to further enhance the cushioning shock absorber, to achieve more comprehensive blocking and buffer shock and sound reduction effects, and long-term use can relatively avoid deformation of the first iron bead bushing, thereby ensuring sliding Smoothness.
