Abstract
Description
Technical field:
[0001] The invention relates to a drawer capable of avoiding left-right shaking when being pulled out, and belongs to the technical field of refrigerators. Background technology:
[0002] The refrigerator drawer will face the problem of shaking left and right when pulling it out. The reason is that the left and right drawer rails are not related, and the left and right pull-out lengths are likely to be inconsistent when pulling them out. During the pulling-out process, the left and right rails are likely to move in opposite directions, one in and one out, and the movement pace is inconsistent, causing the drawer to shake. Most of the existing technologies adopt the solution of adding a synchronous wheel and adding a set of racks on both sides. By making the synchronous wheel mesh and roll in the rack, the rollers on both sides are hard-connected to prevent the drawer door from shaking left and right after being pulled open. There will be problems with misaligned teeth and noise in the existing technology, and there will still be a certain amount of shaking due to the gap in the gears.
[0003] Therefore, it is necessary to improve the existing technology to solve the shortcomings of the existing technology. Summary of the invention:

[0019] The present invention will be further described below in conjunction with the accompanying drawings.
[0020] The present invention can avoid the drawer from shaking left and right when being pulled out. The drawer is installed in a refrigerator. The refrigerator includes a refrigerator door body 1 and a refrigerator liner (not shown). Two spaced drawer guide rails 2 are installed on the inner surface of the refrigerator door body 1 and are perpendicular to the refrigerator door body 1. The upper end of the drawer 3 is installed on the drawer guide rail 2, so that the drawer guide rail 2 can move synchronously with the drawer 3 when moving. A linear guide rail 4 is installed on the refrigerator liner. The linear guide rail 4 includes a left guide rail 40, a right guide rail 41, and a connecting edge 42 connected to the left guide rail 40 and the right guide rail 41. A left front fixed pulley 400 is installed on the end of the left guide rail 40 close to the refrigerator door body 1, and two left rear fixed pulleys 401 are installed on the end of the left guide rail 40 away from the refrigerator door body 1. A right front fixed pulley 410 is installed on the end of the right guide rail 41 close to the refrigerator door body 1, and two right rear fixed pulleys 411 are installed on the end of the right guide rail 41 away from the refrigerator door body 1.
[0021] A wire 7 is installed in the linear guide rail 4, and the specific direction of the wire on the left front fixed pulley 400, the left rear fixed pulley 401, the right front fixed pulley 410 and the right rear fixed pulley 411 is: the left front fixed pulley 400 → the left rear fixed pulley 401 located on the inner side → the right rear fixed pulley 411 located on the inner side → the right front fixed pulley 410 → the right rear fixed pulley 411 located on the outer side → the left rear fixed pulley 401 located on the outer side → the left front fixed pulley 400. In the process of winding the above wire, a left outer wire 402 and a left inner wire 403 are wound between the left front fixed pulley 400 and the left rear fixed pulley 401, and the left outer wire 402 is fixedly connected to the left claw 5. A right outer wire 412 and a right inner wire 413 are wound between the right front fixed pulley 410 and the right rear fixed pulley 411, and the right inner wire 413 is fixedly connected to the right claw 6. The two drawer guide rails 2 are fixedly connected to the left clamping claw 5 and the right clamping claw 6 respectively.
[0022] The distance between the left clamping claw 5 and the refrigerator door body 1 and the distance between the right clamping claw 6 and the refrigerator door body 1 are the same.
[0023] The present invention can prevent the drawer from shaking left and right when being pulled out. The working principle is as follows: when the drawer is pulled outward, the movement direction of the wire is as follows: Figure 4 As shown by the middle arrow, the left claw 5 and the right claw 6 move in the same direction at this time. Since the left claw 5 and the right claw 6 are located on the same line, the speed of movement is also consistent, and the movement distance is also consistent, that is, they move synchronously. Therefore, when pushing and pulling the drawer, the drawer rails on both sides always move in the same direction and synchronously, so that the drawer rails can be pulled out in the same stroke, thereby avoiding the problem of the drawer shaking left and right when being pulled out.
[0024] The above description is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
