Description

Technical Field

[0001] The utility model relates to the field of furniture, in particular to a table top assembly. Background Art

[0002] In order to enrich the functions of computer desks or gaming desks on the market, a magnetic plate that can be attracted by magnets is usually installed on the upper end of the table top near the end of the table top. The magnetic plate is usually an iron plate. This design can give the table top a magnetic function. Users can place decorative figures or various ornaments with magnets in the position where the magnetic plate is installed, making the table top more functional.

[0003] Many existing table tops are made of wooden plywood. In order to take into account both the supporting function and the magnetic function of the table top, a pressing process is usually used to press the magnetic flat plate directly into the interior of the plywood when the plywood is pressed into shape, thereby giving the entire or part of the supporting area at the upper end of the table top a magnetic function. However, this type of table top still has major problems.

[0004] Since the wooden board and the iron board are essentially two boards made of different materials, they cannot be completely pressed together when pressed, resulting in insufficient tightness between the two. In addition, the hardness of the iron magnetic plate is greater than that of the wooden board. Therefore, after long-term use, the magnetic plate inside the table top is prone to warping and deformation due to thermal expansion and contraction. The deformed part of the magnetic plate will squeeze the wooden board, causing it to crack, thus affecting the service life of the table top. Summary of the invention

[0005] In order to solve the above-mentioned technical problems, the purpose of the utility model is to provide a table board assembly, which cooperates the end of the main table board with the U-shaped clamping groove of the magnetic enclosure panel, and makes the magnetic flat plate fit tightly on the supporting surface of the main table board, thereby giving the main table board a stable magnetic function without affecting the service life of the table board.

DETAILED DESCRIPTION

[0045] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0046] In the description of the present invention, the term "at least one" refers to one or more than one, unless otherwise clearly defined. The terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0047] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0048] The utility model has a variety of implementation modes, such as Figure 1-8 As shown, the specific implementation is as follows:

[0049] Example 1: Figure 1 As shown in Figure 5, this embodiment provides a table top assembly, including:

[0050] The main table board 1 is a wooden board, including a horizontal support surface 11 at its upper end;

[0051] The magnetic enclosure 2 is made of a metal material that can be attracted by a magnet, such as an iron material; the magnetic enclosure 2 includes a magnetic flat plate 21, the end edge of the magnetic flat plate 21 extends downward to form a vertical plate 22, and the vertical plate 22 extends horizontally to form a stable flat plate 23; the vertical plate 22 and the stable flat plate 23 constitute an L-shaped plate 26, and a U-shaped clip groove 25 matching the size of the end of the main table board 1 is formed between the vertical plate 22, the stable flat plate 23 and the magnetic flat plate 21, and the end of the main table board 1 is inserted into the U-shaped clip groove 25, and the magnetic flat plate 21 is tightly fitted on the supporting surface 11 of the main table board 1; the simple and practical plug-in cooperation between the U-shaped clip groove 25 and the end of the main table board 1 can quickly install the magnetic flat plate 21 on the supporting surface 11, thereby giving the main table board 1 a magnetic suction function; the end of the main table board 1 can be any end of the four sides of the main table board 1, and this embodiment is explained by connecting the magnetic enclosure 2 to the front end of the main table board 2.

[0052] Furthermore, in order to make the magnetic enclosure 2 fit more closely with the end of the main table board 1, the magnetic enclosure 2 is an elastic plate, and the distance between the magnetic flat plate 21 and the stabilizing plate 23 is less than or equal to the thickness of the main table board 1; specifically, the magnetic flat plate 21, the vertical plate 22, and the stabilizing plate 23 are sheet metal parts formed by integral bending; the sheet metal structure is simple to manufacture and has high strength; the magnetic enclosure 2 with an elastic structure forms an interference fit with the end of the main table board 1, and the magnetic flat plate 21 and the stabilizing plate 23 of the magnetic enclosure 2 will have a clamping effect on the end of the main table board 1, so that the magnetic enclosure 2 and the end of the main table board 1 fit more closely.

[0053] Furthermore, as shown in FIG. 5 , in order to keep the support surface 11 as flat as possible during use, the magnetic plate 2 is usually made of a very thin metal plate. This design does not affect the magnetic function of the table top, reduces the weight of the table top, and is also easy to install. In order to further provide a user experience, a downwardly recessed mounting surface 12 is provided on the support surface 11. The contour of the mounting surface 12 matches the contour of the magnetic plate 21 and is also rectangular. The lower end of the magnetic plate 21 is attached to the mounting surface 12, and the upper surface of the magnetic plate 21 is flush with the support surface 11. The magnetic plate 21 is integrated with the support surface 11 to keep the upper end surface of the entire table top flat.

[0054] Further, if Figure 4 As shown, the magnetic plate 21 is rectangular, and the mounting surface 12 is also rectangular. The rectangular mounting surface 12 intersects with the left and right side walls of the main table board 1 along the left and right directions. On the premise of ensuring the supporting function of the main table board 1, the front end of the main table board 1 is endowed with a magnetic function.

[0055] Furthermore, the magnetic plate 21 is fixed to the mounting surface 12 by gluing; specifically, glue is pre-applied on the mounting surface 12, and when the end of the main table board 1 is inserted into the U-shaped clamping groove 25, this gluing method using glue can fix the magnetic plate 21 on the mounting surface 12, preventing the magnetic plate 21 from detaching upward from the mounting surface 12.

[0056] Furthermore, along the direction inwardly extending from the side wall of the main table top 1, the ratio of the width of the mounting surface 12 to the width of the main table top 1 is in the range of 1:8-1:4; this ratio keeps the area ratio of the magnetic tablet 21 in the table top within a scientific and reasonable range to ensure the best user experience.

[0057] Furthermore, the upper and lower ends of the vertical plate 22 extended from the end edge of the magnetic plate are respectively connected to the magnetic plate 21 and the stable plate 23, and the vertical plate 22 itself is a connecting plate of the magnetic plate 21 and the stable plate 23; because the vertical plate 22 is connected to the magnetic plate 21, when the vertical plate 22 is tightly fitted to the corresponding side wall of the end of the main table panel 1, the magnetic enclosure 2 and the end of the main table panel 1 will be more tightly matched.

[0058] Furthermore, the stabilizing plate 23 fits tightly against the lower end surface of the main table board 1, thereby stabilizing the magnetic plate 21 and preventing the magnetic plate 21 from detaching upward from the mounting surface 12. Specifically, the stabilizing plate 23 is fixed to the lower end of the main table board 1 by means of screw connection. An avoidance hole 24 is preset on the stabilizing plate 23, and a screw hole is preset at the corresponding position of the lower end of the table board 1. The connecting screw 27 passes through the avoidance hole 24 and is screwed into the screw hole at the lower end of the main table board 1, so that the connection between the stabilizing plate 23 and the lower end of the main table board 1 is more stable. The stabilizing plate 23 is connected by screws, which is equivalent to keeping the stabilizing plate 23 fixed in the horizontal and vertical directions, which can prevent the magnetic plate 21 from detaching from the mounting surface 12 in the vertical direction, and can also prevent the magnetic plate 21 and the mounting surface 12 from loosening in the horizontal direction due to loose connection.

[0059] Furthermore, along the direction inwardly extending from the side wall of the main desk board 1, the fitting width between the stabilizing plate 23 and the lower end surface of the main desk board 1 is smaller than the fitting width between the magnetic plate 21 and the mounting surface 12; specifically, the stabilizing plate 23 is mainly used to prevent the magnetic plate 21 from detaching from the mounting surface 12. Therefore, considering the difficulty of installing the magnetic enclosure 2 and the main desk board 1, the fitting width between the stabilizing plate 23 and the lower end surface of the main desk board 1 can be within a reasonable range and does not need to exceed the fitting width between the magnetic plate 21 and the mounting surface 12; in this way, when the end of the main desk board 1 is inserted into the U-shaped slot 25, the fitting width between the stabilizing plate 23 and the lower end surface of the main desk board 1 is smaller, which can reduce the resistance to plug-in while ensuring that the magnetic plate 21 fits the mounting surface 12, thereby reducing the difficulty of assembly.

[0060] Furthermore, in order to expand the supporting area of ​​the main table board 1, the table board assembly also includes an extended table board seamlessly spliced ​​at the left and right side walls of the main table board 1 and the magnetic enclosure 2. The extended table board is flush with the combined main table board 1 and the magnetic enclosure 2 in the horizontal and vertical directions, and the left and right length of the extended table board is smaller than the left and right length of the main table board 1; so as to increase the supporting area of ​​the main table board 1 and make the spliced ​​table board more comfortable to use.

[0061] Furthermore, in order to expand the supporting area of ​​the table top while retaining the magnetic function of the table top, the extended table top includes side magnetic panels 4 and side table panels of equal length on the left and right. The side table panel is equal in length front to back and equal in thickness up and down to the main table panel 1. The side magnetic panels 4 are equal in length front to back and equal in thickness up and down to the magnetic panels 2, and the structure of the side magnetic panels 4 is exactly the same as that of the magnetic panels 2. While the extended table top expands the supporting area of ​​the table top, it also correspondingly expands the magnetic area. This design kills two birds with one stone and has an ingenious structure.

[0062] Furthermore, the extended table board and the main table board 1 are seamlessly spliced ​​by three-in-one fasteners and latches. The latches share the gravity of the extended table board, and the three-in-one fasteners are locked and connected through the eccentric wheel movement. As for the specific structure of the three-in-one fasteners and latches, and the method of tightening the plug-in rod after splicing, please refer to the relevant content in the table board splicing process patent with announcement number CN115503069, which will not be repeated here.

[0063] Example 2: Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that, in order to enhance the aesthetics of the table top assembly and to allow the user to freely select the magnetic area of ​​the table top, in this embodiment, a plurality of magnetic panels 2 are evenly distributed at the end of the main table top 1 along the length direction or the width direction of the main table top 1. This design improves the aesthetics of the table top while giving the table top a magnetic function, and at the same time makes the magnetic area at the end of the table top more diversified.

[0064] Example 3: Figure 7-8 As shown, this embodiment is different from Embodiments 1 and 2 in that another table top assembly is proposed. This table top assembly eliminates the stabilizing plate 23 and uses a vertical plate 22 to prevent the magnetic plate 21 from being separated from the mounting surface 12. The table top assembly includes:

[0065] The main table top 1 includes a horizontal support surface 11 at its upper end;

[0066] The magnetic enclosure 2 includes a magnetic flat plate 21, the end edge of the magnetic flat plate 21 extends downward and forms a vertical plate 22, a V-shaped groove 28 matching the size of the upper corner 13 of the main table top 1 is formed between the vertical plate 22 and the magnetic flat plate 21, the upper corner 13 is in the V-shaped groove 28, and the magnetic flat plate 21 and the vertical plate 22 are respectively tightly fitted on the support surface 11 of the main table top 1 and the corresponding end side wall.

[0067] Furthermore, the magnetic flat plate 21 and the vertical plate 22 are sheet metal parts formed by bending in one piece; the sheet metal part structure is simple to manufacture and has high strength.

[0068] Furthermore, the vertical plate 22 is tightly fitted on the side wall corresponding to the end of the main table board 1 by gluing or screwing; the gluing method is simple and efficient, ensuring that the vertical plate 22 will not be separated from the side wall of the main table board 1, making the connection between the vertical plate 22 and the side wall of the main table board 1 more stable; of course, the use of screw connection can also achieve better results. When the vertical plate 22 is connected to the side wall of the main table board 1 by screws, it is necessary to preset avoidance holes 24 on the vertical plate 22, set screw holes at the corresponding positions of the side walls of the main table board 1, and then pass the connecting screws 27 through the avoidance holes 24 and screw them into the screw holes, so that the vertical plate 22 is stably connected to the side wall of the main table board 1; whether the gluing method or the screw connection method is used, the vertical plate 22 can be kept fixed, and the vertical plate 22 in a fixed state is equivalent to the stable plate 23 in Example 1, which can prevent the magnetic plate 21 from detaching from the mounting surface 12 by stably connecting with the side wall of the main table board 1.

[0069] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
