[0046] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0047] Embodiment 1, as Figures 1 to 4As shown, a space-saving shelf buckle includes a fixing plate 1 for installation on the inner wall of a refrigerator. The fixing plate 1 is arranged vertically. The fixing plate 1 is usually fixed on two opposite surfaces of the refrigerator, and two fixing plates are fixed on each surface. A support slider 2 is slidably provided on the fixing plate 1 along the length direction of the fixing plate. The left and right sides of the fixing plate 1 are provided with a vertically extending guide groove. The support slider 2 is provided with a guide rail that is buckled into the guide groove. A plurality of positioning parts 3 are provided on the fixing plate 1 at intervals along the length direction. The positioning part 3 is a positioning boss. The positioning boss can be in the shape of an arc, an arch, etc. The support slider 2 is provided with a positioning block 4 that can be pressed against the positioning part 3 to position the support slider 2. One end of the positioning block 4 is pressed against the upper end face of the positioning boss to position it. The support slider 2 is provided with an upper opening for one end of the layer frame to be placed in a supporting groove 21 for supporting the layer frame, and the bottom frame or supporting rod of the layer frame is placed in the supporting groove 21. The support slider 2 is rotatably provided with a locking buckle 5 that can cover the opening of the supporting groove 21 and press against the layer frame to lock the layer frame. The left and right side walls of the support slider 2 are respectively provided with mounting grooves 22. The locking buckle 5 is in the shape of a bent rod, and a side wall of the mounting groove 22 is provided with a plug hole 23 for the end of the locking buckle 5 to be relatively rotatably inserted, so that the locking buckle 5 directly presses the layer frame, and the locking buckle 5 does not need to completely cover the supporting groove 21. This can reduce the space for the locking buckle 5 to extend, thereby reducing interference with the space on the layer frame. A positioning device that can press or fix the locking buckle 5 on the layer frame is provided on the support slider 2 and / or the locking buckle 5. The positioning device allows the locking buckle 5 to press or buckle the layer frame, and the positioning device includes an elastic member 61 arranged on the support slider 2 that can press the locking buckle 5 toward one side of the layer frame, and the elastic member is a torsion spring. The locking buckle 5 is provided with a pressing end 51 pressed against the upper end surface of one end of the shelf, and the positioning device includes a pressing end 63 provided on the pressing end 51 and buckled on the side around the upper end surface of one end of the shelf. The pressing end 51 is mainly pressed on the shelf, and the pressing end 63 is mainly buckled on the shelf for positioning, and the pressing end 63 extends relatively downward. A convex buckle 64 is provided in the middle of the buckling end 63, which extends downward and is buckled on the side of one end of the shelf. The convex buckle 64 occupies about one-half of the length of the buckling end 63. The buckling end 63 is shorter downward and does not play a main buckling role. The convex buckle 64 is deeper downward and mainly plays a positioning buckling role. The convex buckle 64 buckles downward on the side and is firmly buckled to prevent the buckling end 63 from being too long and interfering with the shelf. In this way, after the locking buckle 5 rotates, it is buckled on the shelf through the pressing end 62, and the locking buckle 5 is tightened by the pre-tightening force of the positioning pressure block, thereby buckling the shelf, and the torsion spring keeps the locking buckle 5 in a buckled state.

[0048] For ease of use, a positioning protrusion 20 is provided on the side wall of the supporting slider 2, which can position the supporting slider 2 when the locking buckle 5 is rotated to unlock the shelf. The positioning protrusion 20 has an inclined guide sliding surface. The locking buckle 5 slides on the inclined guide sliding surface and then buckles on the back side of the positioning protrusion 20, thereby locking the locking buckle 5 and preventing the locking buckle 5 from being reset. When it needs to be reset, the locking buckle 5 is pushed forcefully to slide out of the positioning protrusion 20 relying on the elastic force of the locking buckle 5.
