Description

Technical Field

[0001] This application mainly relates to the technical field of furniture supplies, and particularly relates to a device that is applied under a long strip-shaped board to play a supporting and anti-deformation role. Background Art

[0002] With the increasing improvement of living standards, consumers have higher and higher demands for diversification and aesthetics in the furniture field. Currently, a type of cabinet with a relatively long length appears on the market, such as bookcases, wine cabinets, TV cabinets, sofa rear cabinets, etc. The common feature of such cabinets is that the length of the horizontal board surface between the side plates is relatively long. Such a horizontal board surface may be integrally formed or may be composed of several boards spliced together. As is well known, the longer the board surface length, the easier it is to bend downward in the middle. Especially for the load-bearing shelves or bottom plates in long strip-shaped cabinets, the bent board surface not only cannot store items normally, but also affects the service life of the board. Of course, the bottom surface of the cabinet is more important. If the horizontal board surface at the bottom is bent, it will also cause the vertical side plates to bend, affecting the stability of the overall structure of the cabinet. Therefore, the conventional solutions are as follows: 1. Adjust the material of the board surface, use a material with better rigidity, or add a rigid support to the board surface, such as a metal frame; 2. Add support feet in the middle of the board surface to lift the middle part of the board surface. However, both of these solutions have their own defects. For Solution 1, whether it is a change in material or a rigid frame, it can only reduce the deformation amplitude of the board surface and cannot make targeted adjustments according to the weight of the stored object and the deformation amplitude. For Solution 2, the added support feet are visible. On the one hand, it is not beautiful, and on the other hand, it will cause obstacles during cleaning. Summary of the Invention

[0003] Aiming at the deficiencies of the existing technology, the utility model aims to provide an anti-deformation device that can be flexibly adjusted according to the deformation amplitude of the horizontal board surface, especially the bottom plate, of a long strip-shaped cabinet during use, and is relatively invisible and will not cause obstruction to cleaning.

[0019] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0020] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0021] As Figures 1-5 shown, the present utility model provides a deformation prevention device for a long-strip cabinet body. This device is applied to the bottom of the horizontal plate surface of the long-strip cabinet body as a support. This kind of horizontal plate surface is not only applied to the bottom of the cabinet, but may also be applied to load-bearing shelves, etc. The material of the plate surface is not limited. Taking the long-strip cabinet body as an example, the cabinet body includes at least two vertical side plates and a horizontal plate surface fixed between the side plates. The horizontal plate surface is preferably the bottom surface of the cabinet body. The device includes a rigid support body 1 arranged below the horizontal plate surface and at least one adjusting device arranged on the support body 1; the support body 1 is strip-shaped and spans as much as possible the two ends in the length direction of the horizontal plate surface to ensure uniform force on each part of the horizontal plate surface. The number of support bodies of the horizontal plate surface is at least 1. The adjusting device includes a support rod member 2 that can move up and down along a direction perpendicular to the length direction of the support body 1 and a limiting member for restricting the position of the support rod member 2; a jacking portion 20 is provided at the top end of the support rod member 2. When the jacking portion 20 moves upward along with the support rod member 2, it can cross the top end of the support body 1 and contact the horizontal plate surface. The limiting member is used to keep the support rod member 2 in the adjusted position.

[0022] The following is an example of the embodiment of the utility model, where the supporting main body 1 is a square tube made of steel. The reason for choosing steel is that the commonly used aluminum alloy material in the furniture field has a large tensile strength and is prone to deformation, while the toughness, anti-torque ability and hardness of steel are greater than those of aluminum alloy. The top end face of the square tube-shaped supporting main body is a plane, which can be closely attached to the bottom surface of the horizontal board surface. When the load-bearing part of the cabinet body deforms, the supporting main body 1 can exert a strong deformation resistance ability, so that the cabinet can maintain a horizontal state and is not easily deformed by sagging. Further, one end of the jacking part 20 of the supporting rod 2 faces upward and contacts the bottom surface of the horizontal board surface. When the deformation of the horizontal board surface exceeds the bearing capacity of the supporting main body 1, the position of the jacking part 20 of the supporting rod can be adjusted to apply an upward jacking force to the horizontal board surface, so as to offset this deformation.

[0023] Since the degree of deformation of the horizontal board surface is uncontrollable, preferably, the adjusting device can achieve a stepless adjustment effect. The supporting rod 2 is in threaded cooperation with the limiting member, and the supporting rod 2 moves up and down in a spiral ascending or descending manner.

[0024] The utility model provides the following several implementation manners of the adjusting device.

[0025] As Figures 1-3 shown, the utility model discloses an embodiment of an adjusting device, including a mounting seat 3. The mounting seat 3 is fixed on one side of the supporting main body 1 and can avoid the supporting main body 1 to provide an avoidance space for adjusting the supporting rod 2. The mounting seat 3 is provided with a first mounting hole 30, and one end of the supporting rod 2 far from the jacking part 20 is inserted into the first mounting hole 30; the first mounting hole 30 can be set as a threaded hole to serve as a limiting member structure. Or the limiting member is an independent component, such as a limiting nut, and the supporting rod 2 is provided with an external thread that cooperates with it.

[0026] Further, the mounting seats 3 are symmetrically distributed on both sides of the supporting main body 1, and the jacking parts 20 synchronously adjust the jacking amplitude, and the force is more balanced.

[0027] Of course, in some embodiments, the mounting seat can also be provided with a threaded hole, and the supporting rod is provided with an external thread and is in threaded cooperation with the mounting seat. By rotating the supporting rod, the spiral ascending of the jacking part is realized. The mounting seat not only plays a role of fixed connection, but also can serve as a limiting member.

[0028] As Figures 4-5As shown, the present utility model provides another embodiment of the adjusting device, which includes a second mounting hole 14' provided on the support body 1'. One end of the support rod 2' away from the jacking portion 20' is inserted into the second mounting hole 14'. The limiting member is an independent component, such as a limiting nut, and the support rod 2' is provided with an external thread that cooperates with it. By rotating the limiting nut or the support rod 2', the spiral rising of the jacking portion 20' is achieved. Of course, in some embodiments, the second mounting hole 14' can be set as a threaded hole to serve as the limiting member structure.

[0029] Furthermore, the exterior of the support body 1 can be designed with additional appearance colors by means such as spraying, veneering, or oxidizing, so as to make it unified with the styles of other parts of the cabinet body and more aesthetically pleasing in appearance.

[0030] For those skilled in the art, various corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all these changes and deformations should fall within the protection scope of the claims of the present utility model.
