Description

Technical Field

[0001] The utility model belongs to the technical field of furniture plate connection, and particularly relates to a three-in-one plate connection structure. Background Art

[0002] Furniture refers to a large category of equipment and facilities that are essential for humans to maintain normal life, engage in production practices and carry out social activities. However, most of the current furniture is installed by splicing multiple panels, and the splicing is done by three-in-one connectors.

[0003] Existing furniture panels need to be spliced with three-in-one connectors, and pre-buried expansion nails need to be driven into the holes of the panels. However, when two panels are fixed at right angles, the expansion nails mainly rely on their own expansion to generate friction with the wall of the panel hole to fix them. This fixing method is relatively simple for fixing panels at right angles. The expansion nails cannot fully expand, and the friction generated is limited, which makes them prone to loosening, resulting in the furniture panels being not firmly connected and shaking, thereby affecting the stability of the furniture panel connection. Summary of the Invention

[0004] The purpose of the present invention is to provide a three-in-one plate connection structure to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: a three-in-one plate connection structure, comprising:

[0006] A connecting rod, one end of which is threadedly connected to a connecting cylinder and one end of which is connected to an expansion rubber cylinder;

[0007] An eccentric wheel is provided with an opening on its surface and a cavity for inserting a connecting rod on one side of the opening. A torsion bend is provided on the surface of the eccentric wheel and one end of the torsion bend is connected to the cavity. By twisting the eccentric wheel, one end of the connecting rod in the cavity is driven to rotate into the torsion bend, so that the connecting rod is stuck in the cavity to fix the plate.

[0008] Preferably, a mounting hole is provided in the plate and a side hole sleeve is provided in the mounting hole.

[0009] Preferably, an opening is provided on the surface of the side hole sleeve, one end of the eccentric wheel rotates through the plate and extends into the opening, a fixed groove is provided in the side hole sleeve, and after the connecting tube is inserted into the fixed groove, the connecting rod extends into the opening.

[0010] Preferably, the top of the connecting rod is inserted into the opening and extends into the cavity after the opening.

[0011] Preferably, a cross hole is provided on the top of the eccentric wheel.

[0012] Preferably, the surface of the expansion rubber cylinder is provided with a spiral tooth segment.

[0013] The invention has the advantages that, compared with the prior art, the invention has the following advantages: the spiral tooth section on the surface of the expansion rubber cylinder at the bottom of the connecting cylinder is screwed and fixed with the threaded hole of one group of plates, and the connecting rod is screwed into the connecting cylinder to make the expansion rubber cylinder fully expand, thereby strengthening the firmness of the connection between the expansion rubber cylinder and the plates, and then the eccentric wheel is screwed into the other group of plates and the end of the eccentric wheel located in the plate extends into the opening of the side hole sleeve, and then the top of the connecting rod is inserted into the side hole sleeve at the bottom of the other group of plates, and inserted into the cavity through the opening on the surface of the eccentric wheel, and the cross hole is screwed by a tool to drive the eccentric wheel to rotate, and the rotating eccentric wheel causes the connecting rod in the cavity to be screwed into the torsion angle. During rotation, the eccentric wheel contacts the connecting cylinder to tighten the connecting rod and clamp it in the torsion angle, and because the connecting rod is located in the torsion angle and away from the opening, the connecting rod is limited in the torsion angle and cannot be separated from the connection with the eccentric wheel from the opening, thereby completing the fixation between the two groups of plates, which is more convenient and the connection is more firm.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to 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 the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0022] The present utility model provides a three-in-one board connection structure as shown in Figure 1-6 and includes:

[0023] A connecting rod 1, one end of the connecting rod 1 is threadedly connected with a connecting cylinder 2 and one end of the connecting cylinder 2 is connected with an expansion glue cylinder 3;

[0024] An eccentric wheel 4, an opening 8 is provided on the surface of the eccentric wheel 4 and a cavity 5 for inserting the connecting rod 1 is provided on one side of the opening 8. A torsion bend angle 6 is provided on the surface of the eccentric wheel 4 and one end of the torsion bend angle 6 communicates with the cavity 5. By turning the eccentric wheel 4, one end of the connecting rod 1 in the cavity 5 is driven to rotate into the torsion bend angle 6, so that the connecting rod 1 is clamped into the cavity 5 to fix the board 7.

[0025] An installation hole 9 is provided in the board 7 and a side hole sleeve 10 is provided in the installation hole 9.

[0026] An opening 11 is provided on the surface of the side hole sleeve 10. One end of the eccentric wheel 4 rotates through the board 7 and then extends into the opening 11. A fixing through groove 14 is provided in the side hole sleeve 10. After the connecting cylinder 2 is inserted into the fixing through groove 14, the connecting rod 1 extends into the opening 11. The shape of the side hole sleeve 10 is cylindrical or elliptical. By passing one end of the eccentric wheel 4 into the opening 11 on the surface of the side hole sleeve 10, the eccentric wheel 4 can be fixed by the side hole sleeve 10, which plays a positioning role for the eccentric wheel 4. The connecting rod 1 passing into the opening 11 can also play a role in positioning and fixing the connecting rod 1 through the side hole sleeve 10, improving the firmness of the connection.

[0027] The top of the connecting rod 1 is inserted into the opening 11 and the opening 8 and then extends into the cavity 5, and the rotating eccentric wheel 4 makes the connecting rod 1 in the cavity 5 screw into the torsion bend angle 6.

[0028] A cross hole 12 is provided at the top of the eccentric wheel 4, which is convenient for a tool to drive the eccentric wheel 4 to rotate through the cross hole 12.

[0029] A spiral tooth section 13 is provided on the surface of the expansion glue cylinder 3. The spiral tooth section 13 on the surface of the expansion glue cylinder 3 at the bottom of the connecting cylinder 2 can be screwed and fixed with the threaded hole of one group of boards 7.

[0030] This three-in-one plate connection structure fixes the spiral tooth section 13 on the surface of the expansion rubber cylinder 3 at the bottom of the connecting cylinder 2 to the threaded hole of one group of plates 7 by screwing, and screws the connecting rod 1 to move it into the connecting cylinder 2, so that the expansion rubber cylinder 3 expands completely, thereby strengthening the firmness of the connection between the expansion rubber cylinder 3 and the plate 7. Then, the eccentric wheel 4 is screwed into the other group of plates 7, and the end of the eccentric wheel 4 located inside the plate 7 extends into the opening 11 of the side hole sleeve 10. Then, the top of the connecting rod 1 is inserted into the side hole sleeve 10 at the bottom of the other group of plates 7, and through the opening 8 on the surface of the eccentric wheel 4, it is inserted into the cavity 5. A tool is used to screw the cross hole 12 to drive the eccentric wheel 4 to rotate. The rotating eccentric wheel 4 makes the connecting rod 1 in the cavity 5 screw into the torsion bending angle 6. When rotating, the eccentric wheel 4 contacts the connecting cylinder 2 to tighten the connecting rod 1 and snap it into the torsion bending angle 6. Since the connecting rod 1 is located in the torsion bending angle 6 and far away from the opening 8, the connecting rod 1 is limited in the torsion bending angle 6 and cannot be detached from the eccentric wheel 4 through the opening 8, thus completing the fixation between the two groups of plates 7, which is relatively convenient and the connection is relatively firm.

[0031] In the present utility model, the side hole sleeve 10 with a circular appearance can also be replaced according to the usage requirements with a side hole sleeve 10 having an elliptical appearance as shown in Figure 5 Figure. [[ID=⑥]] [[ID=⑦]]

[0032] [[ID=⑧]]The bottom of the side hole sleeve 10 has an avoidance groove 15. Inside the avoidance groove 15, there is a convex ring 16 integrated with the side hole sleeve 10. Between the avoidance groove 15 and the convex ring 16, there is a reinforcing rib 17. The avoidance groove 15 is used for injecting glue to ensure a firm connection. The convex ring 16 and the reinforcing rib 17 ensure the strength of the side hole sleeve 10 and reduce the overall weight of the side hole sleeve 10. The bottom of the convex ring 16 does not protrude outside the avoidance groove 15, so as to realize not affecting the assembly of the side hole sleeve 10. [[ID=⑨]] [[ID=⑩]]

[0033] [[ID=⑪]]Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
