[0002] Generally, freezers (refrigerators, refrigerators, etc.) use shelves to store items, and the height between the shelves determines the height of the items that can be placed. However, the height of the items varies, so the shelves need to be adjustable. To prevent the shelves from falling off, adjustable shelves on the market, such as the freezer shelf support device with patent number 202020519643.8 and name "a kind of rotary locking device", use one or two shelf locking parts to close the upper opening of the shelf mounting position, thereby locking part of the shelf and preventing it from jumping out. However, its first rotary locking buckle rotates freely without positioning and is easy to loosen. The second rotary locking buckle is positioned by a snap-lock in the direction of rotation and is easy to loosen when rotating. Neither of these positioning methods is secure. When the shelf jumps or is impacted, the locking buckle is easy to displace or even unlock. [Utility Model Content]

[0064] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Embodiment 1, as shown in the following description. Figures 1 to 4As shown, a convenient and secure latch for locking shelves includes a fixing plate 1 for installation on the inner wall of a freezer. The fixing plate 1 is vertically arranged and is typically fixed on two opposite surfaces of the freezer, with two plates fixed on each surface. Vertically extending guide grooves are provided on the left and right sides of the fixing plate 1, and a guide rail that snaps into the guide groove is provided on the support slider 2. Multiple positioning parts 3 are provided along the length of the fixing plate 1. The positioning parts 3 are positioning bosses, which can be arc-shaped, arched, or other shapes. Positioning parts 3 can also be positioning holes; in this embodiment, the positioning parts 3 are arc-shaped bosses. The support slider 2 is provided with a positioning block 4 that presses against the positioning parts 3 to position the support slider 2. One end of the positioning block 4 presses against the positioning part 3 for positioning, thus preventing the support slider 2 from moving downwards. The support slider 2 has an upper opening for one end of the shelf to be inserted into a support groove 21 for supporting the shelf. The bottom frame or support rod of the shelf is inserted into the support groove 21 and supported by the bottom wall of the support groove 21. The side wall 20 of the support groove 21 is rotatably provided with a locking buckle 5 that can rotate into the opening of the support groove 21 to lock the shelf. The locking buckle 5 presses the shelf on the upper end surface of the inner part of the support groove 21 (e.g., support rod, base frame). The locking buckle 5 rotating into the opening of the support groove 21 does not mean that it is inside the opening of the support groove 21 in a narrow sense, but can be inside or above the opening. The main purpose is to reduce the opening and press or block the shelf. The locking buckle 5 or the side wall 20 is provided with a positioning element 6 that can keep the locking buckle 5 in a locked state. When the locking buckle 5 is in the locked state, one end of the positioning element 6 is on the side wall 20 and the other end is on the locking buckle 5, forming an angle with the locking buckle 5 to press against or lock the locking buckle 5, so that the locking buckle 5 is kept in the locked state. The positioning element 6 forms an angle with the locking buckle 5. One end of the positioning element 6 on the side wall 20 can include the positioning element 6 on the side wall, or on the notch of the side wall, or on the parts (such as the shaft, groove, etc.) on the side wall 20. The side wall 20 does not only refer to the side, but can be any position on the front, back, left, right, middle or groove of the side wall 20. When in the locked state, the locking buckle 5, the positioning element 6 and the side wall 20 form a triangular support. The positioning element 6 can press against or lock the locking buckle 5. The triangular support does not mean that it is formed into a triangle shape, but that the positioning element 6 uses the force of the side wall 20 to keep the locking buckle 5 in the locked state, so that the positioning is firm.

[0065] Furthermore, the positioning element 6 is located above the locking buckle 5. One end of the positioning element 6 is movably connected to or abuts against the locking buckle 5, and the other end abuts against or is movably connected to the side wall 20. In this embodiment, the side wall 20 is provided with a mounting groove 24. When the locking buckle 5 is in the unlocked state, the locking buckle 5 rotates into the mounting groove 24, so that the locking buckle 5 does not protrude most of the mounting groove 24, reducing interference during operation and making it convenient to use. One end of the positioning element 6 abuts against the middle of the locking buckle 5, and the other end is rotatably provided in the mounting groove 24. Both the locking buckle 5 and the positioning element 6 are bent rods. The two ends of the locking buckle 5 and the positioning element 6 are horizontally opened outward and inserted into the two side holes of the mounting groove 24. The locking buckle 5 is provided with a positioning buckle 51 for the positioning element 6 to engage when the locking buckle 5 is in the locked state. The positioning buckle 51 is a step formed by bending the end of the locking buckle 5 towards the middle of the locking buckle 5 and pressing it against the top of the locking buckle 5. The positioning element 6 abuts against one side of the step. When in the locked state, the locking buckle 5 is horizontally positioned.

[0066] To facilitate the positioning and installation of the positioning block 4, the support slider 2 is provided with a positioning mounting groove 41. The positioning block 4 is hinged in the positioning mounting groove 41. The positioning block 4 is provided with a positioning end 42 that can press against the upper end surface of the positioning part 3 for positioning, a locking end 43 located at the lower end of the positioning block 4, and a spring-loaded end 44 located at the upper end of the positioning block 4 opposite to the top wall of the positioning mounting groove 41. A positioning spring 40 is provided between the spring-loaded end 44 and the top wall of the positioning mounting groove 41. The support slider 2 is hinged with a positioning frame 7 that can hold the locking end 43. The positioning end 42 and the locking end 43 are respectively located on both sides of the positioning block 4. The positioning frame 7 holds the locking end 43, so that the positioning end 42 cannot rotate away from the upper end of the positioning part 3.

[0067] Example 2, as Figure 5 As shown, the difference from Embodiment 1 is that, in order to enhance the strength, a bent protrusion is provided in the middle at the end where the positioning member 6 and the locking buckle 5 are abutting.

[0068] Example 3, as Figure 6 and 7 As shown, the difference from Embodiment 1 lies in the positioning method and the locking buckle 5. Specifically, the first positioning part 25 is a positioning step formed by relative bending in the middle of the locking buckle 5. To facilitate the positioning of the locking buckle 5, the mounting groove 24 is provided with a first positioning part 25 that can position the locking buckle 5 when it is in the unlocked and / or locked state. The first positioning part 25 is a positioning boss. When the locking buckle 5 is in the unlocked and locked states, it is respectively fastened to both sides of the positioning boss. The positioning boss protrudes from the side wall of the mounting groove 24 to form two positioning walls, upper and lower. When in the locked state, the locking buckle 5 is positioned on the lower positioning wall of the positioning boss. When in the unlocked state, the locking buckle 5 is positioned on the positioning wall of the positioning boss. The rounded transition of the edges of the two positioning walls facilitates the squeezing and guiding of the locking buckle 5.

[0069] To facilitate the positioning of the positioning component 6, a second positioning part 26 is provided in the mounting groove 24, which can position the positioning component 6 when it is separated from the locking buckle 5. The second positioning part 26 is a convex wall. When the positioning component 6 is in the locked state, it is held in place by the step. When it is in the unlocked state, it rotates to one side of the second positioning part 26.

[0070] To position the positioning frame 7, the side wall of the support slider 2 is provided with a first positioning groove 28 into which the positioning frame 7 slides when it is pressed against the locking end 43, and a second positioning groove 29 into which the positioning frame 7 slides when it is turned away from the locking end 43. The first positioning groove 28 and the second positioning groove 29 are separated by a boss. When the positioning frame 7 is in the locked state, the positioning frame 7 presses against one side of the boss, so that the positioning frame 7 is positioned.

[0071] Example 4, as Figure 8 and 9 As shown, the difference from Embodiment 3 is that the locking buckle 5 has the shape of that in Embodiment 1, and the first positioning groove 28 and the second positioning groove 29 are not provided.

The positioning block 4 is provided with a positioning end 42 that can press against the positioning part 3 for positioning, and a locking mounting end 46 provided on one side of the upper end of the positioning block 4. The positioning torsion spring 45 causes the positioning end 42 to rotate toward the positioning part 3. The locking mounting end 46 is provided with a positioning frame 7 that can rotate and fasten to the lower end of the support slider 2. The lower end of the support slider 2 has a fastening groove to allow the positioning frame 7 to rotate and fasten. The positioning frame 7 is inserted into the upper end of the locking mounting end 46. Pulling down the upper end of the locking mounting end 46 causes the positioning end 42 to rotate toward the positioning part 3. When the positioning frame 7 is fastened to the support slider 2, the positioning end 42 is locked. In this embodiment, the positioning part 3 is an arc-shaped boss.

[0072] Example 5, as Figure 10 and 11 As shown, the difference from Embodiment 4 lies in the positioning and installation method of the positioning block 4.
