Embodiment 1

[0034] see figure 1 with 2 As shown, the present invention is a locking mechanism for a refrigerator drawer, which includes a refrigerator box 1 , a drawer 2 , a sliding block 3 and a latch rod 4 . Two opposite inner walls of the refrigerator box 1 are provided with latch openings 101 .

[0035] Such as image 3 with 4 As shown, a handle groove 201 is provided on the outer surface of one side wall of the drawer 2, and a rectangular cavity 203 corresponding to the position of the handle groove 201 is arranged in the side wall; a handle 202 is rotationally connected to the handle groove 201 . The inner side wall of the rectangular cavity 203 is provided with a slot communicating with the handle slot 201 , and the other two opposite inner walls of the rectangular cavity 203 are both provided with latch slots penetrating through the outer surface of the drawer 2 .

[0036] Such as Figure 5 with 6 As shown, the sliding block 3 is slidingly connected to the inner bottom surfa...

Embodiment 2

[0044] On the basis of Embodiment 1, the shape of the chute 501 is changed to a rectangular trough, and the two opposite side walls of the bar-shaped convex bar 5 are provided with a straight slot 502 communicating with the chute 501; the lower surface of the sliding block 3 is welded or integrated A guide post 304 that fits in a gap with the chute 501 is formed, and the guide post 304 is fixedly connected with a connecting post 305 that fits in a gap with the straight notch 502, so that the sliding block 3 slides along the chute 501 through the guide post 304, and uses the guide post 304 and the straight notch 502, so that the sliding block 3 is connected with the strip-shaped convex strip 5, and the movement is guaranteed to be more stable.

[0045] Meanwhile, the connecting post 305 runs through the straight notch 502, and the connecting rod 302 is rotationally connected with the connecting post 305;

[0046] Therefore, the connecting rod 302 is used to pull the connecting po...

Embodiment 3

[0049] On the basis of embodiment one or embodiment two, such as Figure 4 with 7 As shown, the end of the latch rod 4 that cooperates with the latch port 101 is a wedge-shaped structure, and when the drawer 2 is pushed into the refrigerator cabinet 1, the inclined surface of the wedge-shaped structure is extruded by the inner side wall of the refrigerator cabinet 1, so that the latch rod 4 faces toward the One end of the rectangular cavity 203 moves.

[0050] By setting the end of the latch rod 4 into a wedge-shaped structure, when the drawer 2 is put into the refrigerator cabinet 1, the drawer 2 can be directly pushed toward the refrigerator cabinet 1 . Utilizing the inner wall of the refrigerator box 1 to squeeze the slope of the wedge-shaped structure, the latch rod 4 can be automatically retracted into the latch groove, thereby effectively improving the convenience and efficiency of fixing the drawer.

Abstract

The invention discloses a locking mechanism for a refrigerator drawer, and relates to the technical field of refrigerators. The locking mechanism comprises a refrigerator body, a drawer, a sliding block and a latch rod, wherein pin clamps are arranged in the two inner side walls of the refrigerator body; a handle is rotationally connected to the outer side surface of the drawer, and a rectangular cavity is formed in the side wall of the drawer; the sliding block is connected with the inner bottom surface of the rectangular cavity in a sliding manner, and the sliding block is rotationally connected with a pull rod and a connecting rod and is fixedly connected with a spring; one end of the connecting rod is hinged to the handle, and the connecting rod is used for turning over the handle, pulling the sliding block to move through the connecting rod and pulling the sliding block through the spring, so as to achieve position resetting; and one end of the latch rod is hinged with the pull rod, and the other end is matched with the pin clamps for fixing the position of the drawer. The sliding block and the latch rod are arranged in the drawer, the sliding block is used for driving the latch rod to move axially, and the latch rod is matched with the pin clamps of the refrigerator body, so that the drawer is fixed; and the problems that an existing drawer is tedious in fixing process and low in fixing efficiency are solved.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, in particular to a locking mechanism for refrigerator drawers. Background technique [0002] Existing domestic refrigerators all have drawers for storing food or articles that need to be isolated from each other. As the most important interior part of the refrigerator, the drawer has dual functions of decoration and storage. As the volume of the refrigerator continues to increase, the size of the drawers is getting larger and larger, and the difficulty and requirements for fixing the drawers are getting higher and higher. [0003] In the existing logistics transportation or during the moving process, in order to prevent the drawer itself and other parts from being damaged by collision due to the forward and backward movement of the drawer, it is necessary to use auxiliary materials such as EPS, EPE or tape to fix the drawer to limit the drawer from being damaged. Move back and forth when ...
