Embodiment 1

FIG. 1 and FIG. 2 respectively illustrate an exploded diagram and an assembly finished product diagram of a sliding rail in this embodiment. Referring to FIG. 1 and FIG. 2, a sliding rail includes a base 1, a connecting piece 2, elastic pieces 3 and a slider 4. The sliding rail is of a rectangular structure and uses the base 1 and the slider 4 as a main body structure. The base 1 and the slider 4 are subjected to electroplating treatment, and have an electroplating layer on a surface thereof. The connecting piece 2 and the elastic pieces are accommodated in the base 1 and the slider 4. Correspondingly, the base 1 and the slider 4 are also of the rectangular structure. Two long edges of the base 1 are bent upwards to form U-shaped sliding chutes 11 of the guide rail. Two short edges of the base 1 are protruded upwards and are provided with a block piece 12 respectively. A mounting hole 121 is further provided on the block pieces 12. The mounting holes 121 on the two block pieces are located on a same straight line to mount the connecting piece 2.
In this embodiment, the connecting piece 2 is a shaft which is cylindrical, and is used to position and guide the elastic pieces 3.
For combining with the base 1, a cross section of the slider 4 has a convex structure which is corresponding to a cross section of the base 1. The slider 4 comprises two long outer edges, a sliding strip 41 which is arranged on each long outer edge, and the plates 42 which are extended and bended from a top of the slider 4 downwards. A through hole 421 is provided on the plates 42 respectively. A diameter of each through hole 421 is greater than a diameter of a cross section of the connecting piece 2, and is smaller than a diameter of a cross section of each elastic piece.
In this embodiment, the plates 42 are extended and bent from a middle of the top of the slider 4 downwards, and respectively include a left plate and a right plate (not labeled in the figure).
The elastic pieces 3 are located between the block pieces 12 of the base 1 and the plates 42 of the slider 4, corresponding to the left plate and the right plate of the slider. The elastic pieces include a first spring 31 on a left side and a second spring 32 on a right side.
About the connection between every components, first of all, the connecting piece 2 which is located inside passes through the first spring 31 and the plates 42 (a left plate and a right paddle) of the slider 4 in sequence, and are fixedly mounted on the mounting holes 121 of the block pieces 12. Meanwhile, the sliding strips 41 of the slider 4 are accommodated in the sliding chutes 11, and slides on the base 1 along the sliding chutes 11. It is to be noted that the slider 4 is available to respectively slide to left end and right end of the base 1 along the sliding chutes 11.
By pushing the slider 4 to slide to the right end of the base 1, when the slider 4 slides for a certain distance, which means the slider 4 is not at the original position, the second spring 32 is compressed; and after releasing the slider 4, the second spring 32 pushes the slider to slide to the left and automatically back to an original position. By pushing the slider 4 to slide to the left end of the base 1, when the slider 4 slides for a certain distance, which means the slider 4 is not at the original position, the first spring 31 is compressed; and after releasing the slider 4, the first spring 31 pushes the slider to slide to the right and automatically back to the original position.
In this embodiment, the base and the slider are subjected to electroplating treatment, so that an electroplating layer is formed on a surface of the slider and the base respectively. When the slider slides to left and right on the base, because of the sliding connection between the sliding strips and the sliding chutes, the better smoothness is obtained and the noise is reduced.
According to the sliding rail in this embodiment, because the sliding rail is with a small size, smooth and stable sliding process, low noise and an adjustable sliding force and sliding stroke as required, the sliding rail of the present application effectively improves the user experience of the sliding operation on the sliding rail.
The above contents are merely examples and explanations for the structure of the present invention, and the description is specific and detailed but cannot be understood as a limit to the patent scope of the present invention thereto. It is to be noted that those of ordinary skill in the art may further make a plurality of variations and improvements without departing from the concept of the present invention and these obvious replacement forms all pertain to the protection scope of the present invention.
