For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0027] See also Figure 1-8 As shown, the utility model provides a drawer limiting mechanism for a refrigerator, drawer guide bodies 2 are respectively arranged on the left and right walls of the refrigerator body 1, and the two drawer guide bodies 2 are arranged opposite to each other. A drawer support frame 3 is arranged in the middle of the refrigerator body 1, and a drawer body 8 can be installed on both sides of the drawer support frame 3. Limiting parts are respectively arranged on the left and right walls of the drawer support frame 3, and the limiting parts include a track groove body 4 and a limiting body 5, and the limiting body 5 is located at the front end of the track groove body 4; limiting rib bodies 6 are respectively arranged on the left and right walls of the drawer body 8, and the limiting rib bodies 6 are respectively adapted to the limiting body 5, the track groove body 4 and the drawer guide body 2.
[0028] The utility model provides a drawer limiting mechanism for a refrigerator, wherein a limiting rib body 6 cooperates with a limiting body 5, a track groove body 4 and a drawer guide rail body 2 respectively, so as to reduce the left and right movable range of the drawer body 8 while ensuring that the drawer body 8 can be pulled out and pushed in smoothly, thereby avoiding left and right swinging of the drawer body 8 when pulled out and pushed in, and avoiding uneven gaps caused by offset after the drawer body 8 is pushed in and collision caused by the left and right drawer bodies 8 swinging toward the center when pulled out.
[0029] Specifically, see Figure 2 , Figure 3 As shown, in one embodiment, the limiting body 5 includes a screw column 51, a number one roller 52 and a limiting member, the screw column 51 and the limiting member are both fixedly arranged on the side of the drawer support frame 3, and the limiting member is located above the screw column 51, and the number one roller 52 is rotatably arranged on the screw column 51. The limiting member includes a fixed semi-cylinder 53, on which two raised plate ribs 54 are relatively arranged, and a limiting groove 55 is formed between the two raised plate ribs 54. The limiting rib body 6 is slidably arranged in the limiting groove 55, and the limiting groove 55 is used to limit the limiting rib body 6. In actual production, the width of the limiting groove 55 is only 1 mm larger than the thickness of the limiting rib. After the limiting rib is placed in the limiting groove 55, the movable range of the limiting rib in the left and right directions is 0.5 mm, which reduces the large left and right swing of the drawer body 8 when pulling out and pushing in. The variation range of the matching clearance is at most 0.5 mm. The drawer body 8 is not skewed after being pushed in, and the two drawer bodies 8 do not swing when being pulled out at the same time. There is no possibility of collision between the two drawers, thereby improving the appearance grade of the product.
[0030] See also Figure 4 , Figure 5 As shown, in one embodiment, the limiting rib body 6 includes a transverse limiting rib 61 fixedly arranged on the side of the drawer body 8, and the transverse limiting rib 61 has a longitudinal limiting rib 62 arranged downwardly near the edge of the drawer body 8, and the longitudinal limiting rib 62 is slidably overlapped in the limiting groove 55. Furthermore, front end arc ribs 622 and rear end arc ribs 621 are also provided at both ends of the longitudinal limiting rib 62. The front end arc rib 622 is used to cooperate with the No. 1 roller 52 to prevent the drawer body 8 from being pushed in too quickly and colliding with the inner wall of the refrigerator body 1, and the rear end arc rib 621 is used to cooperate with the No. 1 roller 52 to prevent the drawer body 8 from being pulled out too quickly and falling out of the refrigerator body 1.
[0031] For further information, see Figure 4 , Figure 5As shown, in one embodiment, the left and right walls of the drawer body 8 are also rotatably provided with No. 2 rollers 7, and the No. 2 rollers 7 and the limiting rib body 6 are located on the same axis. After the drawer body 8 is pushed into the refrigerator body 1, the No. 2 rollers 7 on the left and right walls of the drawer body 8 are respectively located in the corresponding drawer guide body 2 and the track groove body 4, which facilitates the smooth pulling out and pushing in of the drawer body 8.
[0032] See also Figure 1 , Figure 2 As shown, in one embodiment, the track groove body 4 includes an upper support surface 41, a lower support surface 42 and a side surface 43 of the groove body. The upper support surface 41, the lower support surface 42 and the side surface 43 of the groove body jointly form a track groove 44 on the left and right walls of the drawer support frame 3, and the No. 2 roller 7 on one side of the drawer body 8 is located in the track groove 44.
[0033] See also Figure 1 , Figure 2 As shown, in one embodiment, the drawer guide includes an upper guide support surface 21, a lower guide support surface 22 and a guide side surface 23. The upper guide support surface 21, the lower guide support surface 22 and the guide side surface 23 together form a guide groove on the left and right inner walls of the refrigerator body 1. The No. 2 roller 7 on the other side of the drawer body 8 is located in the guide groove, and a No. 3 roller 24 is installed at the front end of the guide groove. The No. 3 roller 24 is at the same height as the No. 1 roller 52. The No. 3 roller 24 and the No. 1 roller 52 together maintain the drawer body 8 in a smooth pulling out and pushing in condition.
[0034] When using the utility model:
[0035] When the drawer body 8 is pulled out, the rear end arc rib 621 on one side of the drawer body 8 is stuck on the No. 3 roller 24 on the drawer guide body 2 on the corresponding side of the refrigerator body 1. At this time, the No. 2 roller 7 on this side of the drawer body 8 is pressed upward on the upper support surface 21 of the guide rail on this side of the box body 1; the rear end arc rib 621 on the other side of the drawer body 8 is stuck on the No. 1 roller 52 on the side of the drawer support frame 3. At this time, the No. 2 roller 7 on this side of the drawer body 8 is pressed upward on the upper support surface 41 of the groove body on this side of the drawer support frame 3, so as to limit the pulled out drawer body 8 and prevent the drawer body 8 from directly escaping from the drawer guide body 2 and the drawer support frame 3.
[0036] After the drawer body 8 is pushed in, the drawer body 8 is pushed in by the horizontal limiting ribs 61 on both sides of the drawer body 8 rolling on the corresponding No. 3 roller 24 and No. 1 roller 52, and the No. 2 roller 7 on both sides of the drawer body 8 rolling on the corresponding lower support surface 22 of the guide rail and the lower support surface 42 of the groove body. After being pushed in, the front end arc ribs 622 on both sides of the drawer body 8 are correspondingly stuck on the No. 3 roller 24 and the No. 1 roller 52, preventing the drawer body 8 from continuing to move inward, realizing the limitation of the drawer body 8, so that the drawer body 8 stops at a fixed position after being pushed in, avoiding the drawer body from colliding with the inner wall of the refrigerator body 1 after being pushed in.
[0037] See also Figure 8 As shown, the longitudinal limiting rib 62 on the drawer body 8 is inserted into the limiting groove 55 on the side of the drawer support frame 3. Since the width of the limiting groove 55 is 1 mm larger than the thickness of the longitudinal limiting rib 62, after the longitudinal limiting rib 62 is inserted into the limiting groove 55, the left and right matching clearances between the longitudinal limiting rib 62 and the limiting groove 55 are both 0.5 mm. In this way, the left and right movable range of the longitudinal limiting rib 62 on the drawer body 8 is 0.5 mm, that is, the left and right movable range of the drawer body 8 is limited to 0.5 mm, thereby reducing the left and right movable range of the drawer body 8, avoiding the left and right swinging of the drawer body 8 when pulling out and pushing in, avoiding the uneven gap caused by the offset of the drawer body 8 after being pushed in, and avoiding the collision caused by the left and right drawer bodies 8 swinging toward the center when being pulled out.
[0038] The above detailed description of the preferred embodiments of the utility model should not be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
