[0022] As Figures 1-4 shown, the utility model provides a technical scheme: a drawer guide rail that can prevent impact, including fixed rail 1, the inner wall fixed mounting of fixed rail 1 has inner rail 3, and inner rail 3 is slidably connected with guide rail 2, and inner rail 3 and guide rail 2 are provided with control assembly 4, and control assembly 4 includes: movable rod 41, torsional spring 42, buffer 43, and buffer 43 is used to buffer the force that guide rail 2 pulls, and the movable rod 41 articulated at the top of guide rail 2 will be in contact with the surface of support block 432, because the surface of support block 432 is arc-shaped, thus when contacting the surface of movable rod 41, movable rod 41 can be folded under the support of torsional spring 42, because support block 432 is provided with multiple groups, thus movable rod 41 will be folded gradually in the process of being inserted into guide rail 2, thus the force that the drawer and guide rail 2 are inserted into can be buffered, to prevent guide rail 2 from causing a large impact force to fixed rail 1 when being inserted into fixed rail 1, to avoid the case of damage due to excessive impact force.
[0023] Movable rod 41 is articulated with the surface of guide rail 2, the surface of guide rail 2 is fixedly connected with one side of torsional spring 42, the other side of torsional spring 42 is fixedly installed on the surface of movable rod 41, and movable rod 41 can be folded under the support of torsional spring 42 when being contacted. Buffer 43 includes: rail frame 431, rail frame 431 is fixedly installed on the surface of inner rail 3, the inner wall of rail frame 431 is provided with support block 432, and the setting of support block 432 in rail frame 431 can buffer the moving speed of guide rail 2. The surface of support block 432 is arc-shaped, because the front end of support block 432 is arc-shaped, thus movable rod 41 can be folded when being contacted by support block 432. Elastic sheet 433 is fixedly installed at the bottom of guide rail 2, and the setting of elastic sheet 433 can prevent guide rail 2 from being excessively pulled out. The inner wall of fixed rail 1 is articulated with movable plate 434, the surface of movable plate 434 is fixedly connected with one end of spring 435, the other end of spring 435 is fixedly installed on the inner wall of fixed rail 1, elastic sheet 433 will be in contact with the surface of movable plate 434 when guide rail 2 is inserted into fixed rail 1, so that movable plate 434 extrudes spring 435. Elastic sheet 433 and movable plate 434 are both inclined, because movable plate 434 and elastic sheet 433 are both inclined, thus when guide rail 2 drives elastic sheet 433 to move leftward, the spacing between movable plate 434 and fixed rail 1 will limit elastic sheet 433.
[0024] In the utility model, when using, guide rail 2 is installed at the side of drawer, then guide rail 2 is slid along the surface of inner rail 3 in fixed rail 1, when guide rail 2 moves, the spring piece 433 at the bottom of guide rail 2 contacts the surface of movable plate 434, movable plate 434 is folded, and spring 435 is extruded, at the same time, in the process that guide rail 2 is inserted into inner rail 3, the movable rod 41 articulated at the top of guide rail 2 will contact the surface of supporting block 432, because the surface of supporting block 432 is arc-shaped, when contacting the surface of movable rod 41, movable rod 41 can be folded under the support of torsion spring 42, because supporting block 432 is provided with multiple groups, therefore movable rod 41 will be folded gradually in the process that guide rail 2 is inserted, thus the force that guide rail 2 and drawer are inserted can be buffered, thereby preventing guide rail 2 from causing great impact force to fixed rail 1 when being inserted into fixed rail 1, avoiding the damage caused by too great impact force, and when needing to draw guide rail 2 out of fixed rail 1, when spring piece 433 contacts the position of movable plate 434, it will be clamped into the spacing between movable plate 434 and fixed rail 1, because movable plate 434 and spring piece 433 are both inclined, therefore movable plate 434 can limit spring piece 433, thereby completing the limitation of the force that guide rail 2 is suddenly drawn out, avoiding the drawer guide rail 2 from being excessively pulled out, leading to the drawer guide rail 2 from falling off fixed rail 1, causing the occurrence of safety hazard.
