[0030] See also Figure 1-Figure 7 , shown is a drawer hidden rail structure provided in one embodiment of the utility model, the drawer hidden rail structure includes a guide rail assembly 100 arranged at the bottom of the drawer, a support frame assembly 200 connecting the guide rail assembly 100 and the cabinet, and a buffer 300 arranged on one side of the guide rail assembly 100, wherein:

[0031] In order to replace the connection mode between the drawer 400 and the cabinet body only through the guide rail and the roller, and avoid the heavy pressure between the guide rail and the roller, which causes the roller to be easily worn and the drawer 400 to shake in the cabinet body, the present application provides a guide rail assembly 100. The guide rail assembly 100 includes a sliding rail 120 connected to the drawer 400 and a fixed rail 110 connected to the cabinet body. In this embodiment, since the sliding rail 120 and the fixed rail 110 are both C-shaped guide rails, the sliding rail 120 and the fixed rail 110 can be embedded in each other, and its stability is stronger than the connection mode between the guide rail and the roller. Furthermore, since a sliding member 130 is provided between the sliding rail 120 and the fixed rail 110, and a plurality of rollers are provided on the sliding member 130, and the two sides of the rollers are respectively against the inner side of the sliding rail 120 and the outer side of the fixed rail 110, the sliding member 130 provides rolling force to the sliding rail 120 and the fixed rail 110, and is also used to separate the sliding rail 120 and the fixed rail 110, and provide supporting force to both. Therefore, by providing the sliding member 130, the sliding rail 120 and the fixed rail 110 can be embedded in each other and can slide against each other.

[0032] In order to reduce the impact of the drawer 400 during use, a buffer 300 needs to be installed on the side of the sliding rail 120 away from the side of the drawer 400. Therefore, at least two connecting pieces 121 extend from the side of the sliding rail 120 away from the side plate of the drawer 400 in its sliding direction. The connecting piece 121 includes a connecting portion 122 connected to the sliding rail 120 and a clamping portion 123 for clamping the buffer 300. In order to facilitate the installation of the buffer 300, the angle between the clamping portion 123 and the connecting portion 122 is in the range of 90°-120°. Directly, the clamping portion 123 is tilted outward by 0-30° to clamp the buffer 300.

[0033] In order to clamp the buffer 300 on the sliding rail 120, connection snap-in sockets 310 used in conjunction with the connection piece 121 are provided at both the front and rear ends of the buffer 300. When installing the buffer 300, align the connection buckle of the buffer 300 with the connection piece 121 provided on the side wall of the sliding rail 120, pre-align the connection snap-in sockets 310 through the connection piece 121, and push the buffer 300 in the direction of being pulled away from the drawer 400, so that the connection piece 121 is clamped into the connection snap-in sockets 310, and the buffer 300 is pressed against the side wall of the sliding rail 120 to complete the pre-installation.

[0034] Furthermore, in order to better connect the cabinet and the drawer 400, at least one support frame assembly 200 is provided along the length direction of the fixed rail 110 to support the fixed rail 110 and further support the drawer 400. The support frame assembly 200 includes a first support sheet 210 and a second support sheet 220 connected in an L shape, and the first support sheet 210 and the second support sheet 220 are respectively provided with a first type of connection hole 211 for connecting the cabinet and a second type of connection hole 221 for connecting the fixed rail 110. Compared with the difference between the cabinet and the fixed rail 110, the diameter of the first type of connection hole 211 is smaller than the diameter of the second type of connection hole 221, so that the cabinet and the fixed rail 110 are respectively connected with fasteners of different diameters.

[0035] It is worth emphasizing that, in order to enhance the firmness between the first support sheet 210 and the second support sheet 220 , a plurality of reinforcing ribs 230 are further provided at the connection between the first support sheet 210 and the second support sheet 220 .

[0036] In summary, according to a drawer hidden rail structure provided by the utility model, by connecting the sliding rail to the drawer, using the fixed rail and the support frame assembly to connect to the cabinet, and then utilizing the function of the sliding rail and the fixed rail to penetrate each other, the rolling force is provided by the sliding member, which replaces the connection method of the transmission roller and the guide rail, and improves the stability of the drawer hidden rail structure. Specifically, the guide rail assembly includes a sliding rail connected to the drawer and a fixed rail connected to the support frame assembly, and the fixed rail and the sliding rail penetrate each other. The structural connection stability of the fixed rail and the sliding rail penetrating each other is stronger than that of the roller and the guide rail, and a sliding member is provided inside the fixed rail and the sliding rail to provide sliding force. At the same time, the other end of the support frame assembly is directly connected to the cabinet to support the hidden rail structure. In order to provide a buffering function, the buffer is arranged at one end of the sliding rail away from the support frame assembly to reduce the impact on the drawer during use and extend its service life.
