[0001] The utility model relates to the technical field of furniture shelf supports, in particular to a shelf support and limit structure for furniture. Background Art
[0002] Furniture shelves are horizontal wooden boards used to partition space and carry items in furniture, and they are widely used in various types of furniture, such as bookcases, wardrobes, cabinets, etc.
[0003] The shelves made of furniture wood are generally supported, limited and supported by triangular brackets made of aluminum alloy and wood screws.
[0004] Specifically, the triangular brackets are first installed into the inner cavity of the wooden cabinet through wood screws, and then the furniture wood shelves are fixed on the triangular brackets through wood screws, so as to realize the installation and limitation of the furniture wood shelves.
[0005] At present, for the existing installation and limit structure of furniture wood shelves, the spacing volume size between the shelf and the inner cavity of the wooden cabinet is not convenient to adjust and limit, and it cannot be conveniently adjusted and limited according to the height of the items to be stored, which greatly reduces the application flexibility of the installation and limit structure of furniture wood shelves.
[0006] In addition, for the existing installation and limit structure of furniture wood shelves, the limit anti-rotation stability after height adjustment is relatively low.
[0007] The above problems are common and urgently need to be improved. Summary of the Utility Model

Specific embodiments
[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0028] Referring to Figures 1-5 , a layer board support and limit structure for furniture, including a layer board 1, a wooden cabinet body 2 is provided around the layer board 1, an inner sleeve 6 and a support rib plate 11 are arranged on the layer board 1, an adjusting screw hole 61 is opened in the inner sleeve 6, an embedded groove 21 is opened on the wooden cabinet body 2, an embedded vertical board 3 is arranged in the embedded groove 21, a first fixing plate 4 and a second fixing plate 5 are arranged on the embedded vertical board 3, an adjusting screw 7 is arranged on the first fixing plate 4 and the second fixing plate 5, an adjusting dial 71 and a limit nut 8 are arranged on the adjusting screw 7, a smooth coating 32 and a wood screw 31 are arranged on the embedded vertical board 3, an anti - rotation pressure ring 81 is arranged on the limit nut 8, and a damping limit layer 82 is arranged on the anti - rotation pressure ring 81. The layer board 1 is a common furniture wood - based material board on the wooden cabinet body 2, which is the prior art.
[0029] The wood screws 31 are two groups symmetrically arranged up and down, and each group has two screws symmetrically arranged front and back. The wood screws 31 pass through the embedded vertical board 3 and are fixedly arranged with the wooden cabinet body 2, ensuring the installation stability of the embedded vertical board 3.
[0030] A bearing 51 is embedded in the second fixing plate 5 , and the adjusting screw 7 is threadedly connected to the first fixing plate 4 and fixedly sleeved with the bearing 51 . The bearing 51 is a ball bearing to prevent the adjusting screw 7 from slipping off the second fixing plate 5 .
[0031] There are two supporting ribs 11 symmetrical on the left and right. The supporting ribs 11 are of overall triangular structure and are arranged on the lower end surface of the layer plate 1. The supporting ribs 11 are made of plastic steel with high strength, and the triangular structure is stable and strong, which improves the support durability of the layer plate 1.
[0032] There are two built-in sleeves 6 that are symmetrical on the left and right. The adjusting screw hole 61 vertically penetrates the built-in sleeves 6 and is threadedly connected to the adjusting screw 7. The built-in sleeves 6 are embedded in the layer board 1 and bonded by special glue.
[0033] The limiting nut 8 is threadedly connected to the adjusting screw 7. The anti-rotation pressure ring 81 is arranged on the upper end surface of the limiting nut 8 and has a thickness of thirty to forty millimeters. The anti-rotation pressure ring 81 is made of vulcanized rubber, has high resilience and is durable.
[0034] The damping and limiting layer 82 is arranged on the upper end surface of the anti-rotation pressure ring 81 . The damping and limiting layer 82 is a silicone damping coating, which has damping friction, is wear-resistant and durable.
[0035] The adjusting dial 71 is arranged at the lower end of the adjusting screw 7, and a finger-shift groove 72 is provided on the adjusting dial 71. The top-view cross-section of the finger-shift groove 72 is a V-shaped groove. There are eighteen finger-shift grooves 72 arranged in a circle. The fingers are inserted into the finger-shift grooves 72 and the adjusting dial 71 is turned, which improves the convenience of turning the adjusting dial 71, and the V-shaped groove can prevent the fingers from slipping when turning.
[0036] The smooth coating 32 is evenly coated along the inner wall surface of the embedded vertical plate 3, and the smooth coating 32 is in sliding contact with the side wall surface of the layer plate 1. The smooth coating 32 is a ceramic coating with a smooth and flat surface and low friction.
[0037] The inner wall surface of the embedded vertical board 3 is higher than the embedded groove 21, and the side wall surface of the layer board 1 does not contact the inner wall surface of the wooden cabinet body 2. When the vertical height of the layer board 1 is adjusted, contact and friction between the layer board 1 and the inner wall surface of the wooden cabinet body 2 can be avoided.
[0038] Working method: insert fingers into the finger grooves 72 on both sides, and then rotate forward and reverse at the same time, and drive the adjusting screw 7 to rotate forward and reverse through the adjusting dials 71 on both sides, and the height of the shelf 1 can be adjusted downward or upward through the threaded transmission with the adjusting screw hole 61 in the built-in sleeve 6. When the storage spacing volume size between the shelf 1 and the inner cavity of the wooden cabinet 2 is adjusted to the required storage spacing volume size, stop turning the adjusting dial 71, and the vertical height of the shelf 1 can be adjusted according to the height requirements of the stored items, thereby improving the application flexibility of the installation limit structure for the wooden shelf of furniture.
[0039] Moreover, after adjusting the shelf 1 to the required height, hold the adjusting dial 71, then rotate the limit nut 8 clockwise. The limit nut 8 is driven to move upward through the threaded transmission between the adjusting screws 7. Stop rotating the limit nut 8 after the damping limit layer 82 at the upper end of the limit nut 8 makes damping contact with the lower end surface of the first fixing plate 4. At this time, the anti-rotation retaining ring 81 will be squeezed and generate a vertical resilience force. This vertical resilience force acts on the adjusting screw 7, which can prevent the adjusting screw 7 from self-rotating. At the same time, the damping friction limit effect of the damping limit layer 82 can further improve the limit anti-self-rotation loosening effect of the adjusting screw 7, and overall improve the limit anti-self-rotation stability after the height adjustment is completed.
[0040] In addition, when the vertical height of the shelf 1 is adjusted, the outer wall surfaces of the shelf 1 and the support rib plates 11 will smoothly slide along the smooth coating 32 on the embedded vertical plate 3, greatly improving the smoothness between the shelf 1 and the embedded vertical plate 3 during vertical adjustment.
[0041] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present utility model.
