Description

Technical Field

[0001] This utility model relates to the field of shelf technology, specifically to a shelf locking mechanism and a shelf support device. Background Technology

[0002] Freezers, display cases, and other similar cabinets utilize shelves to hold more items. These shelves are typically supported and secured by shelf support devices, which also allow for height adjustment, enhancing usability. When installing shelves onto the support devices, the shelf locking mechanism must be used to secure them firmly.

[0003] Existing shelf support devices, such as the utility model patent with authorization announcement number CN 221997266 U, disclose a shelf mounting device including a slide rail 100 and a mounting buckle 200; the upper end of the mounting buckle 200 is provided with a shelf mounting locking structure, including a front stop block 211 and a rear stop plate 212, with a shelf mounting position 213 formed between the front stop block 211 and the rear stop plate 212; the rear stop plate 212 is provided with a locking metal part 214, the rear end of which is rotatably connected to the rear stop plate 212, and the front end is detachably fastened to the front stop block 211, and when the rear stop plate 212 is pried open, the locking metal part 214 separates from the front stop block 211 and automatically flips upward. However, the above-mentioned shelf mounting locking structure still has the following shortcomings:

[0004] 1. In the above structure, the mounting buckle 200 is slidably and adjustablely mounted on the slide rail 100, and the rear baffle 212 is mounted on the end of the mounting buckle 200 near the slide rail 100. When separating the locking metal piece 214 from the front stop 211, it is necessary to pry the rear baffle 212. When prying it, it is necessary to put your hand between the rear baffle 212 and the slide rail 100. Since the space between the rear baffle 212 and the slide rail 100 is narrow, it is very difficult and inconvenient to pry the rear baffle 212.

[0005] 2. The locking metal part 214 needs the elasticity of the rear baffle 212 to make the locking metal part 214 fasten onto the front baffle 211. The rear baffle 212 and the mounting buckle 200 are integrated. After long-term use, the elasticity of the rear baffle 212 is easily weakened and the structure is unstable. After the elasticity is weakened, the locking metal part 214 will not be able to fasten onto the front baffle 211 effectively, and the locking metal part 214 will easily loosen. When repairing, the entire mounting buckle 200 needs to be replaced, which is costly. Utility Model Content

[0006] The purpose of this utility model is to overcome the above-mentioned problems and provide a shelf locking mechanism that is easy to operate, has a very stable structure, can be used for a long time, and has low maintenance costs.

[0007] Another objective of this invention is to provide a shelf support device that includes the aforementioned shelf locking mechanism.

[0008] The objective of this utility model is achieved through the following technical solution:

[0009] A shelf locking mechanism includes a sliding support for mounting on a slide rail, a mounting plate and a fastening plate disposed on the sliding support and spaced apart from each other, a placement groove for inserting a shelf is formed between the mounting plate and the fastening plate, and a fastening locking assembly is provided between the mounting plate and the fastening plate; the fastening locking assembly includes a rotating member, a locking member and an elastic member; one end of the rotating member is rotatably connected to the mounting plate, the other end of the rotating member is hinged to one end of the locking member, and the other end of the locking member is detachably fastened to the fastening plate; one end of the elastic member acts on the mounting plate, and the other end of the elastic member acts on the rotating member.

[0010] The working principle of the above-mentioned shelf locking mechanism is as follows:

[0011] The elastic force of the spring element causes the rotating part to swing upward, allowing the locking part to securely engage with the fastening plate. To disassemble, press down on the rotating part; it overcomes the elastic force and swings downward, causing the locking part to move. Under the action of the fastening plate, the locking part rotates relative to the rotating part, flipping outward and separating from the fastening plate. Release the hand; under the elastic force of the spring element, the rotating part and locking part swing upward together, opening the shelf slot. To engage, press down on the rotating part and engage the locking part with the fastening plate to lock the shelf in the shelf slot, preventing it from falling out and improving the stability of the shelf installation.

[0012] In a preferred embodiment of this utility model, the mounting plate is a vertical plate. By setting the plate vertically, its sides are smooth and flat, facilitating the placement of the shelf rack into the storage slot, resulting in a more compact structure.

[0013] Preferably, the upper end of the mounting plate is provided with a hinge hole, and the rotating component is rotatably connected to the hinge hole. The hinge hole facilitates the installation of the rotating component.

[0014] Preferably, the elastic element is a torsion spring, which is sleeved on the rotating component. One end of the torsion spring acts on the mounting plate, and the other end acts on the rotating component. By using a torsion spring, not only is the structure compact, but the torsion spring also has strong elasticity, which ensures that the locking component can be firmly fastened to the fastening plate and is not easily loosened.

[0015] Preferably, the mounting plate has a mounting groove, and one end of the torsion spring is located in the mounting groove and abuts against the inclined surface of the mounting groove. In the above structure, by providing an inclined surface in the mounting groove, the torsion spring is facilitated to bear force, and by providing the mounting groove, one end of the torsion spring can be installed in the mounting groove, ensuring the compactness of the structure.

[0016] Preferably, the upper end of the fastening plate is provided with a fastening hook, and the lower end of the fastening hook is provided with a fastening groove, and one end of the locking member can be detachably fastened to the fastening groove. In the above structure, the fastening hook can block the locking member, the fastening groove can accommodate the locking member, and the fastening hook combined with the fastening groove realizes the fastening of the locking member and the fastening plate.

[0017] Preferably, the lower end of the fastening groove is provided with a downwardly inclined guide surface. By providing the inclined guide surface, during disassembly, pressing down on the rotating component by hand causes it to swing downwards against the elastic force of the elastic component, driving the locking component to move. Under the limitation of the fastening groove, the locking component rotates relative to the rotating component, flips outwards, separates from the fastening hook, and disengages from the fastening groove into the inclined guide surface. As the rotating component continues to be pressed down, guided by the inclined guide surface, the end of the locking component further flips outwards until the end of the locking component moves away from the fastening hook. After releasing the rotating component, under the elastic force of the torsion spring, the rotating component and the locking component swing upwards together, passing over the fastening hook, thus separating the locking component from the fastening hook. The inclined guide surface plays a good guiding role for the locking component. During fastening, pressing down on the rotating component by hand overcomes the elastic force of the torsion spring, causing the rotating component to swing downwards, driving the locking component to swing as well. Then, the end of the locking component is fastened into the fastening groove. After releasing the hand, the elastic force of the torsion spring can securely fasten the locking component to the fastening plate.

[0018] Preferably, both the rotating component and the locking component are rod-shaped structures. The rod-shaped structure facilitates installation and also saves costs.

[0019] A shelf support device includes a slide rail and a shelf locking mechanism, wherein the sliding support base is slidably and adjustably mounted on the slide rail.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] 1. The shelf locking mechanism in this utility model has a locking component set between the mounting plate and the locking plate. When disassembling, it can be done by pressing down on the rotating part without being blocked by the slide rail. The large operating space greatly improves the convenience of operation.

[0022] 2. The shelf locking mechanism in this utility model, by setting an independent elastic element, can make the locking element securely fastened to the fastening plate, and the structure is very stable. After long-term use, the elastic force of the elastic element can also fully ensure that the locking element is securely fastened to the fastening plate. If the elastic force weakens, only the elastic element needs to be replaced, without replacing the entire sliding support base, so the maintenance cost is low. Attached Figure Description

[0031] To enable those skilled in the art to fully understand the technical solution of this utility model, the present utility model will be further described below in conjunction with the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0032] See Figures 1-8This embodiment discloses a shelf locking mechanism, including a sliding support 1 for mounting on a slide rail 11, a mounting plate 2 and a fastening plate 3 disposed on the sliding support 1 and spaced apart from each other, a placement groove 4 for inserting a shelf is formed between the mounting plate 2 and the fastening plate 3, and a fastening locking assembly is provided between the mounting plate 2 and the fastening plate 3; the fastening locking assembly includes a rotating member 5, a locking member 6 and an elastic member 7; one end of the rotating member 5 is rotatably connected to the mounting plate 2, the other end of the rotating member 5 is hinged to one end of the locking member 6, and the other end of the locking member 6 is detachably fastened to the fastening plate 3; one end of the elastic member 7 acts on the mounting plate 2, and the other end of the elastic member 7 acts on the rotating member 5.

[0033] See Figures 1-6 The mounting plate 2 is a vertical plate. By setting it as a vertical plate, its sides are smooth and flat, making it easier for the shelves to be placed into the placement slot 4, and the structure is more compact.

[0034] See Figures 1-6 The mounting plate 2 has a hinge hole 2-1 at its upper end, and the rotating component 5 is rotatably connected to the hinge hole 2-1. The hinge hole 2-1 facilitates the installation of the rotating component 5.

[0035] See Figures 1-6 The elastic element 7 is a torsion spring, which is sleeved on the rotating element 5. One end of the torsion spring acts on the mounting plate 2, and the other end acts on the rotating element 5. By setting the torsion spring, not only is the structure compact, but the torsion spring also has strong elasticity, which can make the locking element 6 securely fastened to the fastening plate 3, and it is not easy to loosen.

[0036] See Figures 1-6 The mounting plate 2 is provided with a mounting groove 2-2, and one end of the torsion spring is located in the mounting groove 2-2 and abuts against the inclined surface of the mounting groove 2-2. In the above structure, by providing an inclined surface in the mounting groove 2-2, the torsion spring is facilitated to bear force, and by providing the mounting groove 2-2, one end of the torsion spring can be installed in the mounting groove 2-2, ensuring the compactness of the structure.

[0037] See Figures 1-7 The upper end of the fastening plate 3 is provided with a fastening hook 8, and the lower end of the fastening hook 8 is provided with a fastening groove 9. One end of the locking member 6 can be detachably fastened to the fastening groove 9. In the above structure, the fastening hook 8 can block the locking member 6, and the fastening groove 9 can accommodate the locking member 6. The fastening hook 8 combined with the fastening groove 9 realizes the fastening of the locking member 6 and the fastening plate 3.

[0038] See Figures 1-7The lower end of the fastening groove 9 is provided with a downwardly inclined guide surface 10. By setting the inclined guide surface 10, when disassembling, pressing down on the rotating part 5 by hand causes the rotating part 5 to swing downward against the elastic force of the elastic part 7, driving the locking part 6 to move. Under the limitation of the fastening groove 9, the locking part 6 will rotate relative to the rotating part 5, flip outward, separate from the fastening hook 8, and disengage from the fastening groove 9 into the inclined guide surface 10. As the rotating part 5 is pressed down further, under the guidance of the inclined guide surface 10, the end of the locking part 6 will further flip outward until the end of the locking part 6 is far away from the fastening hook 8. After releasing the rotating part 5, under the elastic force of the torsion spring, the rotating part 5 and the locking part 6 swing upward together and pass over the fastening hook 8, realizing the separation of the locking part 6 from the fastening hook 8. The inclined guide surface 10 plays a good guiding role for the locking part 6. When fastening, press down on the rotating part 5 with your hand to overcome the elastic force of the torsion spring, causing the rotating part 5 to swing downward, which in turn causes the locking part 6 to swing as well. Then, fasten the end of the locking part 6 into the fastening groove 9. After releasing your hand, the elastic force of the torsion spring can securely fasten the locking part 6 onto the fastening plate 3.

[0039] See Figures 1-5 The inclined guide surface 10 is inclined downward in a direction away from the mounting plate 2.

[0040] See Figures 1-7 Both the rotating component 5 and the locking component 6 are rod-shaped structures. The rod-shaped structure facilitates installation and also saves costs. The rotating component 5 includes a U-shaped rod 5-1 and a first transverse reinforcing rod 5-2 located at the open end of the U-shaped rod 5-1. The first transverse reinforcing rod 5-2 improves the overall strength of the rotating component 5. The locking component 6 includes a rod body 6-1 and a second transverse reinforcing rod 6-2 located at the open end of the rod body 6-1. The rod body 6-1 is 7-shaped. The second transverse reinforcing rod 6-2 improves the overall strength of the locking component 6. The locking component 6 and the rotating component 5 have relatively high friction, requiring a certain force to rotate relative to each other; this is to ensure the stability of the structural connection.

[0041] See Figures 1-5 The sliding support 1, mounting plate 2, and fastening plate 3 are integrated into one structure, ensuring the compactness of the structure.

[0042] See Figures 1-7 The working principle of the above-mentioned shelf locking mechanism is as follows:

[0043] The elastic force of the elastic element 7 causes the rotating element 5 to swing upward, allowing the locking element 6 to be securely fastened to the fastening plate 3. During disassembly, pressing down on the rotating element 5 causes it to overcome the elastic force of the elastic element 7 and swing downward, moving the locking element 6. Under the action of the fastening plate 3, the locking element 6 rotates relative to the rotating element 5, flipping outward and separating from the fastening plate 3. Releasing the hand allows the rotating element 5 and the locking element 6 to swing upward together under the elastic force of the elastic element 7, thus opening the placement slot 4. For fastening, pressing down on the rotating element 5 and fastening the locking element 6 into the fastening plate 3 completes the fastening process, locking the shelf in the placement slot 4 and preventing it from falling out, thus improving the stability of the shelf installation.

[0044] See Figures 1-7 This embodiment also discloses a shelf support device, including a slide rail 11 and a shelf locking mechanism as described in Embodiment 1, wherein the sliding support seat 1 is slidably and adjustablely mounted on the slide rail 11.

[0045] The above are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
