Description

Technical Field

[0001] The utility model relates to the field of furniture, in particular to a magnetic table top assembly and a magnetic table top. 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] Furthermore, the side walls of a magnetic table top are usually flat vertical surfaces, but as users have higher and higher requirements for the appearance of the table top, users will want to make the side walls of the table top into different shapes, such as a slope or a triangle. Since table tops with side walls of various shapes break people's conventional ideas about the appearance of table tops, they have a strong visual appeal to users and are therefore popular. However, changing the side walls of a table top while retaining the magnetic function has become a problem.

[0004] 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 magnetic function to all or part of the supporting area at the upper end of the table top. However, wooden boards and iron plates are essentially panels of two different materials. Therefore, when pressed, the wooden boards and iron plates cannot be completely pressed together, resulting in insufficient tightness between the two. If the side walls of the table top are directly cut to change the shape, the iron plate is likely to warp and deform during processing, and the magnetic flat plate of the deformed part will squeeze the wooden board, causing the wooden board to crack, thereby affecting the service life of the table board. Summary of the invention

[0005] In order to solve the above-mentioned technical problems, the purpose of the utility model is to provide a magnetic table top assembly, which forms a molded plate assembly of a predetermined shape at the front end side wall of the supporting substrate by completely covering and flattening the flat plate on the upper end surface of the supporting substrate, thereby indirectly and effectively changing the shape of the front end side wall of the supporting substrate; the magnetic table top assembly does not require direct grinding of the side wall of the supporting substrate, and effectively changes the shape of the magnetic table top without destroying the structure of the supporting substrate and retaining the magnetic function of the table top, thereby improving the aesthetics of the magnetic table top.

[0006] A magnetic table top is further provided. By presetting the magnetic table top component as a splicing module and splicing the splicing module at the side wall of the main table top, the user can quickly change the shape of the side wall of the main table top, thereby quickly improving the aesthetics of the table top.

[0013] Preferably, the first molding plate, the second molding plate, the third molding plate and the side wall of the front end of the support base plate form a mounting groove, and a rigid support member is provided in the mounting groove, and the rigid support member completely fills the mounting groove in the left and right directions. The rigid support member can provide sufficient structural strength for the molding plate assembly to prevent the molding plate assembly from structural deformation due to the hollow structure of the mounting groove.

[0014] Preferably, the two second vertical plates extend forward and form two limiting portions at the left and right ends of the installation slot, and the two limiting portions respectively abut against the left and right ends of the rigid support member; the limiting portions formed by the second vertical plates can limit the left and right movement of the rigid support member to prevent the rigid support member from falling out of the installation slot.

[0015] Preferably, the flat plate, the forming plate assembly, the first vertical plate and the second vertical plate are sheet metal parts that are bent in one piece. The sheet metal part structure is simple to manufacture and has high strength.

[0016] Preferably, it also includes a bottom magnetic plate that is buckled on the lower end of the supporting substrate, and the bottom magnetic plate includes a bottom plate that is completely attached to and fixed on the lower end surface of the supporting substrate, and the rear end and left and right ends of the bottom plate extend upward to form a third vertical plate that is tightly attached to the corresponding side wall of the supporting substrate; thereby giving the lower end of the supporting substrate a magnetic attraction function.

[0017] Preferably, the bottom plate is fixed to the lower end of the support substrate by screw connection; the lower end of the bottom plate is unsupported, so the screw installation method can stably fix it to the lower end of the support substrate.

[0018] Furthermore, a magnetic table top is provided, including a magnetic table top assembly and a main table top. The magnetic table top assembly can be combined into a splicing module with a supporting substrate as a splicing carrier, and the splicing module can be seamlessly spliced ​​on any side wall around the main table top.

[0020] Preferably, the front-to-back length of the splicing module is smaller than the front-to-back length of the main table top, making it easier to splice the splicing modules.

The extended table board is equal in length front to back to the main table board, and the left and right length of the extended table board is smaller than that of the main table board.

[0023] The principle of the utility model using the above technical solution is:

[0024] The utility model aims to provide a magnetic table top assembly, which forms a molding plate assembly of a predetermined shape at the front end side wall of the supporting base plate only by extending the flat plate which completely covers and flattens the upper end surface of the supporting base plate forward.

[0025] Furthermore, a magnetic table top is provided, in which the table top assembly is pre-set as a splicing module, and the splicing module is spliced ​​at the corresponding side wall position of the main table top.

[0026] The beneficial effects of the utility model using the above technical solution are:

[0027] The magnetic table top assembly is based on a flat plate that completely covers and is flatly fixed on the upper end surface of a supporting base plate, with the front edge of the flat plate as the starting end, so that the flat plate extends outward from the supporting base plate along a predetermined path, and forms a molded plate assembly of a predetermined shape at the front end side wall of the supporting base plate. The contour of the molded plate assembly can give the entire structure of the magnetic table top assembly without destroying the structural strength of the supporting base plate, while retaining the magnetic function of the table top, and at the same time changing the side wall shape of the supporting base plate, thereby improving the aesthetics of the magnetic table top assembly.

[0028] In the magnetic table top, the magnetic table top assembly can also be used as a pre-installed splicing module to be spliced ​​on the side wall of the main table top.

DETAILED DESCRIPTION

[0038] 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.

[0039] 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.

[0040] 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.

[0041] The utility model has a variety of implementation modes, such as Figure 1-8 As shown, the specific implementation is as follows:

[0042] Example 1: Figure 1-7 As shown, the present embodiment provides a magnetic table top assembly, which can be set to a reasonable size and support area to become a magnetic table top with a support function, comprising a support base plate 4 and a magnetic enclosure plate, the support base plate 4 comprising vertical side walls 41 on all sides, the magnetic enclosure plate comprising a flat plate 11 matching the upper end face contour of the support base plate 4, the flat plate 11 being flat and fixed on the upper end face of the support base plate 4; the front end edge of the flat plate 11 extends outward from the support base plate 4 along a predetermined path, and forms a molded plate assembly 16 of a predetermined shape at the front end side wall of the support base plate 4.

[0043] Furthermore, in order to stabilize the flat panel 11 above the supporting substrate 4, the flat panel 11 is fixed to the upper end surface of the supporting substrate 4 by gluing; the gluing method is simple and efficient, and can effectively prevent the flat panel 11 from detaching from the upper end surface of the supporting substrate 4 upward.

[0044] Further, if Figure 1-2As shown, in order to make the installation and fixing effect of the rear end of the flat plate 11 more stable, the edge of the rear end of the flat plate 11 extends downward to form a first vertical plate 17 that is tightly attached to the rear end side wall of the supporting substrate 4; the first vertical plate 17 can make the installation of the flat plate 11 and the supporting substrate 4 more stable, and form a reinforcement structure at the rear end of the flat plate 11 to avoid deformation of the rear end of the flat plate 11.

[0045] Furthermore, in order to make the installation and fixing effect of the left and right ends of the flat plate 11 more stable, the left and right edges of the flat plate 11 extend downward to form two second vertical plates 12 respectively attached to the left and right side walls of the supporting substrate 4; the second vertical plates 12 can make the installation of the flat plate 11 and the supporting substrate 4 more stable, and form a reinforcement structure in the left and right directions of the flat plate 11 to avoid deformation of the left and right ends of the flat plate 11.

[0046] Furthermore, the molding plate assembly 16 is formed as follows: the portion of the front end of the flat plate 11 that extends beyond the side wall of the supporting base plate 4 forms a first molding plate 15, the first molding plate 15 further extends inward and obliquely downward to form a second molding plate 13, the second molding plate 13 extends horizontally backward to form a third molding plate 14, the first molding plate 15, the second molding plate 13, and the third molding plate 14 together constitute a U-shaped molding plate assembly 16; thereby blocking the vertical side wall of the supporting base plate 4, and giving the table top assembly a sloped side wall in appearance through the second molding plate 13.

[0047] Further, if Figure 3-5 As shown, the first molding plate 15, the second molding plate 13, the third molding plate 14 and the side wall of the front end of the support base plate 4 form a mounting groove 18. In this embodiment, the second molding plate 13 is in the shape of an inclined surface, so a right-angled trapezoidal mounting groove 18 is formed between the molding plate assembly 16 and the vertical side wall 41 of the support base plate 4; the mounting groove 18 is equivalent to forming a hollow groove in front of the first side wall 41 of the support base plate 4, so when the molding plate assembly 16 is subjected to external force, the molding plate assembly 16 is easily deformed. The external force can be a human pressing force or a clamping force at the molding plate assembly 16. The clamping force generated by the display bracket, therefore, in order to avoid deformation of the forming plate assembly 16, a rigid support member 2 is provided in the mounting groove 18. The rigid support member 2 is a tubular profile made of metal. The tubular structure is light and stable, with high structural strength, which can not only meet the rigid support of the mounting groove 18, but also will not generate too much gravity on the third forming plate 14; the rigid support member 2 completely fills the mounting groove 18 along the left and right directions; the rigid support member 2 can provide sufficient structural strength for the forming plate assembly 16 to avoid structural deformation of the forming plate assembly 16 due to the hollow structure of the mounting groove 18.

[0048] Furthermore, in order to prevent the tubular rigid support member 2 from sliding out along the left and right openings of the mounting groove 18, the two second vertical plates 12 extend forward and form two limiting portions 12a at the left and right ends of the mounting groove 18. The two limiting portions 12a are respectively abutted against the left and right ends of the rigid support member 2; the limiting portions 12a formed by the second vertical plates 12 can limit the left and right movement of the rigid support member 2 to prevent the rigid support member 2 from slipping out of the mounting groove 18.

[0049] Furthermore, the flat plate 11, the forming plate assembly 16, the first vertical plate 17, and the second vertical plate 12 are sheet metal parts that are bent in one piece; the sheet metal parts have a simple structure and high strength.

[0050] Further, if Figure 7 As shown, in order to expand the magnetic attraction area of ​​the supporting base plate 4 so that the lower end of the supporting base plate 4 can also absorb magnetic parts, the magnetic table top assembly also includes a bottom magnetic attraction plate 3 that is buckled on the lower end of the supporting base plate 4. The bottom magnetic attraction plate 3 includes a bottom plate 31 that is completely attached to and fixed on the lower end surface of the supporting base plate 4. The rear end and left and right ends of the bottom plate 31 extend upward to form a third vertical plate 32 that is tightly attached to the corresponding side wall of the supporting base plate 4. The bottom plate 31 and the third vertical plate 32 are also sheet metal parts that are bent as one piece, which can also give the lower end of the supporting base plate 4 a magnetic attraction function.

[0051] Furthermore, the third vertical plate 32 and the first vertical plate 17 and the second vertical plate 12 form an adjustment gap s relative to each other up and down; the adjustment gap s can reserve installation space for the bottom magnetic enclosure plate 4 to avoid interference between the supporting base plate 4 and the upper magnetic plate during installation.

[0052] Furthermore, the bottom plate 31 is fixed to the lower end of the support substrate 4 by means of screw connection; this is because the lower end of the bottom plate 31 has no support, and thus the screw installation method can stably fix it to the lower end of the support substrate 4.

[0053] like Figure 6 As shown, a magnetic table top is provided, including a magnetic table top assembly and a main table top 5, the magnetic table top assembly can be combined into a splicing module 1 with a supporting substrate 4 as a splicing carrier, and the splicing module 1 can be seamlessly spliced ​​on any side wall around the main table top 5; the structural design enables the magnetic table top to simplify the process of changing the vertical shape of the side wall of the main table top 5 into a simple splicing process, so that the main table top 5 can quickly change the side wall shape of the table top according to different usage requirements, thereby improving the aesthetics of the table top; therefore, it is more suitable for mass production of magnetic table tops with different side walls.

[0054] Furthermore, considering the usage area of ​​the magnetic table top, the splicing module 1 is configured to be seamlessly spliced ​​on the front end side wall of the main table top 5; and the splicing module 1 and the main table top 5 are equal in length left and right, and equal in thickness up and down; the front end side wall is the main magnetic usage area in life, and the splicing module 1, which is equal in length left and right and equal in thickness up and down, can be flush with the main table top 5 after splicing, maintaining good integrity.

[0055] Furthermore, the role of the splicing module 1 in the magnetic table top is mainly to change the side wall shape of the main table top 5, so it does not require a very long front and rear length, and therefore the front and rear length of the splicing module 1 is smaller than the front and rear length of the main table top 5; it not only changes the side wall shape of the main table top 5, but also makes the splicing module 1 easier and more convenient to assemble.

[0056] Furthermore, in order to expand the supporting area of ​​the magnetic table top, the magnetic table top also includes an extension table top 8 seamlessly spliced ​​to the left and right side walls of the main table top 5 and the splicing module 1. The extension table top 8 is equal in length to the main table top 5 front to back, and the left and right length of the extension table top 8 is smaller than the left and right length of the main table top 5. The extension table top 8 remains flush with the main table top 5 in the horizontal and vertical directions. After the extension table top 8 is spliced ​​onto the main table top 5, the supporting area of ​​the main table top 5 can be increased, making the table top more comfortable to use.

[0057] Furthermore, in order to expand the supporting area of ​​the magnetic table top and the corresponding magnetic area at the same time, the extended table top 8 includes a side table top 6 and a side splicing module 7 of equal length on the left and right. The side table top 6 is equal in length to the main table top 5 front to back, and the side splicing module 7 is equal in length to the splicing module 1 front to back, and the side splicing module 7 has the same structure as the splicing module 1. The extended table top 8 expands the supporting area of ​​the table top while correspondingly expanding the magnetic area. This design kills two birds with one stone and has an ingenious structure.

[0058] Furthermore, each splicing module and each table top is seamlessly spliced ​​together through three-in-one fasteners and latches. The latches share the gravity of the extended table tops, and the three-in-one fasteners are locked and connected through an eccentric wheel movement. Regarding the specific structure of the three-in-one fasteners and latches, and the specific tightening method after splicing, please refer to the relevant content in the table top splicing process patent with announcement number CN115503069, which will not be repeated here.

[0059] Example 2: Figure 8 As shown, the difference between this embodiment and embodiment 1 is that the second molding plate 13 in this embodiment is V-shaped, that is, the second molding plate 13 first extends obliquely forward and downward, and then extends obliquely backward and downward, thereby forming a V-shaped contour, making the molding plate assembly 16 more diversified in appearance; at the same time, the contour change of the molding plate assembly 16 also causes the inner cavity of the mounting groove 18 and the outer contour of the rigid filling member 2 to undergo corresponding changes, which are no longer the right-angled trapezoid in embodiment 1, but a pentagon.

[0060] Furthermore, the variation of the second forming plate 13 in the forming plate assembly 16 is not limited to the slope shape or V-shape. In fact, the forming plate assembly 16 can be formed into a variety of shapes according to a predetermined path, such as semicircle, wave, triangle, etc.

[0061] 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.
