In this embodiment, there are two support buckles 1, which are arranged in a horizontal interval, one of which is close to the refrigerator door leaf, and the other is close to the refrigerator back plate. The support buckle 1 is provided with a support groove 11 with an upper end opening and a guide rail 2 that is installed in the support groove 11 and has both ends extending horizontally from the support groove 11. The support groove 11 is a U-shaped groove. Figure 1The X axis is horizontal, the Y axis is longitudinal, and the Z axis is vertical, or the length direction of the guide rail 2 is horizontal. The guide rail 2 is provided with a slider 3 that can slide along the length direction of the guide rail 2. The slider 3 is provided with a buckling part that can be buckled on the shelf 10 so that the slider 3 can be driven when the shelf 10 is pushed or pulled. The buckling part is buckled with the shelf 10 so that the shelf 10 and the slider 3 are linked. The guide rail 2 is provided with a first positioning device 4 and a second positioning device 5 that can block the sliding of the slider 3 at intervals along the length direction of the guide rail 2. When the shelf 10 is pulled out relative to the guide rail 2, or when it is pulled out of the refrigerator, it is positioned by the second positioning device 5, and the shelf 10 cannot be pulled outward. When the shelf 10 is pushed back onto the track 2, or when it is pushed back into the refrigerator, it is positioned by the first positioning device 4 to prevent the shelf 10 from hitting the back plate of the refrigerator. The first positioning device 4 is provided at the rear end of the track 2 (close to one end of the back plate of the refrigerator), and the second positioning device 5 is provided at the front end or middle part of the track 2. In this embodiment, the second positioning device 5 is provided in the middle part of the track 2 near the front end. A lateral positioning device 6 that can position the guide rail 2 horizontally and a vertical positioning device 7 that can position the guide rail 2 vertically are provided between the support buckle 1 and the guide rail 2. The guide rail 2 is installed from the opening of the support buckle 1 and is positioned by the lateral positioning device 6 and the vertical positioning device 7, so that the guide rail 2 is fixed by the support buckle 1. The structure is simple and the installation is convenient.

[0048] A guide slot 21 is provided in the guide rail 2, and the guide slot 21 extends longitudinally.

The shelf 10 can be pressed against the support end 36, and the support end 36 is a bending block, and the bending block support end 36 is horizontal, and the bottom end of the shelf 10 is pressed against the support end 36. The first positioning device 4 and the second positioning device 5 are respectively inserted into the guide slot 21 and block the slider 3 to prevent the pulley 32 from sliding out of the guide slot 21. The first positioning device 4 and the second positioning device 5 are blocking rods provided on the guide rail 2 and one end of which penetrates into the guide slot 21 and can block the pulley 32. In this embodiment, the blocking rod is a screw. In order to ensure smooth pushing and pulling of the shelf 10, an end 22 is inserted into the end of the guide rail 2 away from the first positioning device 4, and a guide pulley 23 is provided on the end 22 for supporting and guiding the shelf 10. The guide pulley 23 can rotate, and the guide pulley 23 can play a supporting and guiding role.

[0049] Specifically, the vertical positioning device 7 includes a guide convex rail 71 provided at the bottom of the guide rail 2 and extending along the length direction of the guide rail 2, and a clamping groove 72 provided at the bottom of the support groove 11 for the guide convex rail 71 to be inserted. The clamping groove 72 clamps the guide convex rail 71 from the left and right sides. The clamping groove 72 is symmetrically arranged on the left and right sides of the support groove 11, and the opening of the clamping groove 72 faces the middle of the support groove 11. In this embodiment, the clamping groove 72 is a dovetail groove, and the guide convex rail 71 is dovetail-shaped or figure eight-shaped. The horizontal positioning device 6 is a positioning port 65 provided on the side wall of the guide rail 2 and a positioning block 15 provided on the support buckle 1 that can be inserted into the positioning port 65. The lower end of the positioning block 15 is integrally connected to the support buckle 1, and the upper end of the positioning block 15 extends vertically. The positioning block 15 has a certain elastic reset force. When the positioning block 15 is moved, the positioning block 15 can be moved out of the positioning port 65. During installation, the two support buckles 1 are respectively inserted from the two ends of the guide rail 2, the end of the guide rail 2 is laterally inserted from the side of the support groove 11, and the guide protrusion 71 is inserted into the clamping groove 72. When the positioning block 15 is inserted into the positioning port 65, the support buckle 1 and the guide rail 2 are installed in place. The structure is simple and the installation is convenient. The support buckle 1 is then installed on the fixing plate 40.

The positioning buckle 12 can be moved to break away from the notch 61. There are two notches 61. The two bent edges of the positioning buckle 12 can be inserted into one notch 61 one by one. The positioning buckle 12 can be relatively rotatable and provided on the support buckle 1. When the positioning buckle 12 is moved and rotated, the end of the positioning buckle 12 is inserted into the notch 61. In this way, the positioning buckle 12 blocks the guide rail 2 horizontally. There are positioning convex points on the side wall of the support buckle 1. When the end of the positioning buckle 12 is inserted into the notch 61, it is positioned by the positioning convex points to prevent the positioning buckle 12 from automatically rotating out, thereby locking the positioning buckle 12. The clamping groove 72 is a C-shaped groove at the bottom of the support groove 11, and the guide convex rail 71 is a horizontal convex edge inserted into the C-shaped groove. The stopper 34 is provided with one, and the inner side 20 and the crossbeam 30 are provided between the hook 33 and the stopper 34 .

The stamped convex edge 62 is stamped and protruded on the guide convex rail 71, so that it can block the side of the first positioning side wall 13. This has a simple structure and is easy to install. The guide convex rail 71 is shaped like an eight, and two stamped convex edges 62 are arranged on each guide convex rail 71. The stamped convex edges 62 on each guide convex rail 71 correspond to the support buckles 1 one by one, and the stamped convex edges 62 are between the two support buckles 1.

The positioning convex edge 63 is stamped and protruded from the side wall of the guide rail 2. The positioning convex edge 63 is turned to form an arc convex edge after stamping, so that it is blocked against one side of the second positioning side wall 14. There are two positioning convex edges 63, which correspond to the support buckles 1 one by one. The positioning convex edge 63 close to the second positioning device 5 is on the left side of the second positioning side wall 14, and the positioning convex edge 63 away from the second positioning device 5 is on the right side of the second positioning side wall 14, that is, the two positioning convex edges 63 are between the two support buckles 1. During installation, the two support buckles 1 are respectively inserted from the two ends of the guide rail 2, and the end of the guide rail 2 is inserted laterally from the side of the support groove 11, and the guide convex rail 71 is inserted into the clamping groove 72.
