Detailed implementation manners

[0056] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0057] Embodiment 1, as Figures 1 to 4 shown, a shelf buckle for a lock support beam includes a fixing piece 1 for mounting on the inner wall of a freezer. The fixing piece 1 is vertically arranged and is usually fixed on two opposite surfaces of the freezer, with two fixed separately on each surface at intervals. A support slider 2 is slidably arranged on the fixing piece 1 along the length direction of the fixing piece 1. Guide chutes extending vertically are arranged on the left and right sides of the fixing piece 1, and guide rails inserted into the guide chutes are arranged on the support slider 2. A plurality of positioning parts 3 are arranged on the fixing piece 1 along the length direction. The positioning parts 3 are positioning bosses, and the positioning bosses can be in shapes such as arcs and arches. The positioning parts 3 can also be positioning holes. In this embodiment, the positioning parts 3 are arc-shaped bosses. A positioning block 4 capable of pressing against the positioning parts 3 to position the support slider 2 is arranged on the support slider 2. One end of the positioning block 4 presses against the positioning parts 3 for positioning, so that the support slider 2 can no longer move downward. A support slot 21 with an upper end opening for one end of the shelf to be placed in for supporting the shelf is arranged on the support slider 2. A support beam 20 is arranged inside the outer frame 10. The shelf is composed of the outer frame 10 and the support beam 20. The support beam 20 is perpendicular to the part of the outer frame 10 placed in the support slot 21. The outer frame 10 is square-shaped. The cross-section of the support slot 21 can be U-shaped. The upper end, the front side, and the rear side of the support slot 21 are all open. The front side refers to the side close to the freezer door leaf, and the rear side is opposite to the front side, or in other words, the rear side is the side of the freezer back. The side of the freezer back can also be expressed as the side in the depth direction of the freezer. A locking buckle 5 capable of locking the support beam 20 and being toggled to unlock the support beam 20 is arranged on the support slider 2. The locking buckle 5 can press above the support beam 20 to lock the shelf to prevent the shelf from jumping out. A blocking part 30 capable of blocking the support beam to prevent the outer frame from moving out of the freezer is also arranged on the support slider. In this way, the shelf cannot move outward from the freezer and cannot be taken out upward, making the shelf in a completely locked state.

[0058] In order to enable the shelf to improve the bearing capacity, a support part 22 for supporting the support beam 20 is arranged on the support slot 21, that is, the support slot 21 can also support the support beam 20. A vertical wall 23 is arranged on the side of the support slot 21 away from the fixing piece 1. The support part 22 is arranged on one side of the vertical wall 23. The blocking part 30 is the side edge of the vertical wall 23. In order to enable both sides of the shelf to be installed, the shelf buckle can be used when installed on the left and right side walls of the freezer without distinction. Two support parts 22 are arranged on the left and right sides of the vertical wall 23 respectively, and the left and right side edges of the vertical wall 23 are both blocking parts 30. For the convenience of installation, the locking buckle 5 is arranged on the vertical wall 23.

[0059] For ease of use, the locking buckle 5 is reset by elastic force after being unlocked by toggling it. Specifically, the locking buckle 5 includes a buckle portion 51 extending to the left and right sides to press the support beam 20 and an elastic portion 52 connecting the two buckle portions 51. By providing two buckle portions 51, the two buckle portions 51 are symmetrically arranged, so that no matter whether the mounting shelf buckle is installed on the left or right wall of the refrigerator, it can be used without distinction. When the two buckle portions 51 are pressed together, the elastic portion 52 is squeezed by the buckle portion 51 to unlock the support beam 20. When the buckle portion 51 is released, the two buckle portions 51 are relatively opened under the action of the elastic portion 52 to lock the support beam 20.

[0060] For easy installation, a mounting groove 24 for accommodating the locking buckle 5 is provided on the vertical wall 23. The upper end of the mounting groove 24 is open, and the buckle portion 51 is pressed against the inner wall of the mounting groove 24 when it is opened. The mounting groove 24 is provided with a first positioning portion 25 for positioning the buckle portion 51 when the buckle portion 51 is in an unlocked state, and a second positioning portion 26 for positioning the buckle portion 51 when the buckle portion 51 is in a locked state. The first positioning portion 25 can be a groove, and the second positioning portion 26 can be a groove or a positioning wall. In this way, the locking buckle 5 cannot move at will regardless of whether it is in a locked or unlocked state, thereby reducing interference.

[0061] In this embodiment, the locking buckle 5 is formed by bending a rod, the elastic part 52 is a torsion spring, the pressing buckle part 51 is integrally formed at both ends of the torsion spring, and a mounting column 27 for the torsion spring to be sleeved is provided in the mounting groove 24.
