[0002] The invention belongs to the field of furniture manufacturing, and in particular relates to a table with a magnetic connection mechanism. Background Art

[0003] Joining tables are a type of furniture that is becoming increasingly popular among consumers. The connecting mechanism used in traditional joining tables is difficult to assemble and disassemble. The connecting mechanism is easily damaged and prone to plastic deformation, which affects the tolerance. It is also laborious to operate and the experience is not good. Summary of the invention

[0004] In order to make up for the deficiencies of the prior art, the present invention provides a technical solution of a table with a magnetic connection mechanism.

[0005] A table with a magnetic connection mechanism, comprising a plurality of unit tables with magnetic connection mechanisms, wherein the unit tables are connected and installed by means of the magnetic connection mechanisms they each have; The magnetic connection mechanism includes a housing, a buckle mounted in the housing, and a magnetic member mounted on the buckle. When the magnetic member is attracted by a magnetic member in another magnetic connection mechanism, the outer end of the buckle can be driven to extend from the housing to achieve the buckle connection with the buckle in another magnetic connection mechanism. The housing has a cavity for accommodating the buckle, the cavity has an opening for the buckle to extend out, and the bottom wall of the cavity is an inclined structure that can make the buckle in an inclined state, and when the buckle is disengaged from the buckle of another magnetic connection mechanism, it can automatically slide back to its original position by its own gravity; The outer end of the buckle is provided with a hook for clamping.

[0006] Furthermore, the housing cavity has buckle limit grooves on both sides, and the buckle has buckle limit parts on both sides for slidingly cooperating with the buckle limit grooves. When the outer end of the buckle extends out of the housing cavity to the extreme position, the buckle limit parts are blocked with the outer side walls of the buckle limit grooves.

[0007] Furthermore, the inclination angle of the bottom wall of the buckle limiting groove is greater than the inclination angle of the bottom wall of the cavity, and when the buckle extends out of the cavity to the limit position, the buckle is in a horizontal state.

DETAILED DESCRIPTION

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] like Figure 1-8As shown, a magnetic connection mechanism includes a housing 10, a buckle 11 mounted in the housing 10, and a magnetic member 12 mounted on the buckle 11. When the magnetic member 12 is attracted by a magnetic member 12 in another magnetic connection mechanism 1, the outer end of the buckle 11 can be driven to extend out of the housing 10 to achieve the buckle 11 and the buckle 11 in another magnetic connection mechanism 1. The magnetic member 12 is preferably a magnet.

[0016] As an optimization: the shell 10 has a cavity 100 for accommodating the buckle 11, the cavity 100 has an opening for the buckle 11 to extend out, the top of the shell 10 has a cover plate 13 covering the container 100, and the bottom wall of the cavity 100 is an inclined structure that can make the buckle 11 in an inclined state. When the buckle 11 is disengaged from the buckle 11 of another magnetic connection mechanism 1, it can automatically slide and reset by its own gravity.

[0017] In the above structure, the housing 10 has buckle limit grooves 101 on both sides of the cavity 100, and the buckle 11 has buckle limit parts 110 on both sides for slidingly cooperating with the buckle limit grooves 101. When the outer end of the buckle 11 extends out of the housing 100 to the extreme position, the buckle limit part 110 blocks the outer wall of the buckle limit groove 101.

[0018] Furthermore, the inclination angle of the bottom wall of the buckle limit groove 101 is greater than the inclination angle of the bottom wall of the cavity 100, so that the inner end of the buckle 11 is gradually raised during the process of extending out of the cavity 100, and then the buckle 11 gradually becomes horizontal. When the buckle 11 extends out of the cavity 100 to the extreme position, the buckle 11 is exactly in a horizontal state.

[0019] As an optimization, two sides of the outer end of the buckle 11 are respectively provided with hooks 111 for clamping.

[0020] In the above structure, at least one pair of buckles 11 is arranged in the shell 10, preferably one pair, wherein the hooks 111 of the two buckles 11 in the pair of buckles 11 are arranged one upward and the other downward, and the outer wall of the hook 111 is inclined, so that it can play a guiding role when the hooks 111 of the two magnetic connection mechanisms 1 gradually approach each other.

[0021] Furthermore, the magnetic poles of the magnetic members 12 on the two buckles 11 are arranged in opposite directions.

[0022] like Fig. 9As shown, a table includes a plurality of unit tables 2 having the magnetic connection mechanism 1 as described above, and the unit tables 2 are snap-fitted and installed with each other through the magnetic connection mechanism 1 they each have. The unit table 2 also has conventional structures such as a table top 20, table legs 21, table wheels 22, height adjustment support columns 24, and a crossbeam 23. More specifically, the magnetic connection mechanism 1 is mounted on the bottom edge of the table top 20 of the unit table 2. When two unit tables 2 are snap-fitted and installed, the table tops 20 of the two unit tables 2 abut against each other. In the two snap-fitted magnetic connection mechanisms 1, the outer end of each buckle 11 extends into the cavity 100 of the other magnetic connection mechanism 1 to snap-fit ​​with the corresponding buckle 11.

[0023] The unit table 2 has magnetic connection mechanisms 1 on all sides, so that the table can be infinitely expanded in area by stacking the unit tables 2, and the shape of the table can be changed by splicing different parts of the unit tables 2. A magnetic connection mechanism 1 of the present invention can be applied to a table, a desk, a training table, etc., to achieve rapid connection, and has the advantages of convenient disassembly and good user experience. The magnetic connection mechanism 1 is fixed to a table top 20 by self-tapping screws.

[0024] In the magnetic connection mechanism 1, the cover plate 13 and the housing 10 are both ABS plastic parts and are connected by interference fit. The cover plate 13 ensures that the buckle 11 will not fall off. The magnetic part 12 is a rectangular parallelepiped structure, and its interference fit is embedded in the buckle 11 made of PA+GF plastic. The buckle 11 is embedded in the housing 10 through clearance fit and has relative displacement freedom. In simple terms: the housing 10 and the cover plate 13 do not have relative motion, and the magnetic part 12 and the buckle 11 do not have relative motion. The buckle 11 and the housing 10 have relative motion. When the two magnetic connection mechanisms 1 approach each other head-on, the opposite poles of the magnetic part 12 attract each other, and the magnetic part 12 drives the buckle 11 to slide relative to the housing 10 as a whole. Since the magnetic force of the magnetic part 12 is greater than the sum of the gravity of the buckle 11 and the magnetic part 12 and the friction between the buckle 11 and the housing 10, Newton's second law phenomenon occurs, and the outer end of the buckle 11 extends out of the cavity 100 of the housing 1. Not only is the longitudinal component of the magnetic force of the magnetic piece 12 greater than twice the sum of the gravity of the buckle 11 and the magnetic piece 12, but the lateral component of the magnetic piece 12 is greater than the direct friction force of the buckle 11. Then, the two docked buckles 11 in the two magnetic connection mechanisms 1 have relative movement. Since the longitudinal movement is restricted by the shell 10, lateral movement occurs, causing the hooks 111 of the buckles 11 to hook together, and the hooks 111 of the buckles 11 will extend into the cavity 100 of the shell 1 of the other magnetic connection mechanism 1 when hooked, and there will be no gap between the shells of the two magnetic connection mechanisms 1.

[0025] When the table top 20 is manually pulled, the applied external force is much greater than the magnetic force of the magnetic member 12, the friction between the table leg 21 and the ground, the elastic deformation force of the two buckles 11, etc., and the magnetic connection mechanism 1 is disengaged. The two buckles 11 are elastically deformed to form a height difference, and move relative to each other under the action of the artificial external force. After disengagement, the gravity is greater than the longitudinal component of the friction between the buckle 11 and the housing 10, and the buckle 11 slides to the original position, avoiding the buckle 11 from being in a leaking state after disengagement.

[0026] The housing 10 is provided with a snap-on limit groove 101. The magnetic poles of the magnetic member 12 are respectively distributed on the large surface of the direction, ensuring that a larger magnetic force is provided to overcome the friction and gravity when splicing. The magnetic poles of the two magnetic members 12 in each magnetic connection mechanism 1 are arranged in opposite directions, ensuring that all magnetic connection mechanisms can be spliced ​​together.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
