Description

  The present invention relates to a fixing device for a slide rail kit that can be operated more conveniently and can be stably attached to a rack.

  Patents 1 and 2 by Greenwald et al., And prior patents 3 and 4 invented by LIN et al. Disclosed a fixing device for a slide rail kit. .

  The structure disclosed in each of the above-mentioned prior patents includes a hook-shaped arm having a hook portion, a spring that provides elasticity and applies a force to the hook-shaped arm, and a mounting part having a hole. Among these, the hook-shaped arm is inserted into the hole of the mounting part, and the hooking portion of the hook-shaped arm is extended out of the hole of the mounting part by the elasticity generated by the spring. Since the hook-shaped arm directly penetrates the mounting part, when the mounting part is mounted in the hole of the support pillar of the rack and positioned, the hooking portion of the hook-shaped arm extends to the outside of the hole of the mounting part.
