Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a furniture connection structure with multiple fixing functions. Background Technology

[0002] Furniture connection structures are the structural parts that assemble various components of furniture. These include mortise and tenon joints, hinges, screws, and three-in-one connectors, all of which are crucial for ensuring the stability and overall performance of the furniture. Using connection structures with multiple fixing functions is significant. From a stability perspective, for example, when a dining table is subjected to external forces such as heavy objects, the combination of mortise and tenon joints and hardware enhances stability. This structure is better suited for furniture components of diverse materials and shapes; for instance, in wooden furniture, mortise and tenon joints combined with screws strengthen the connection. In terms of durability, three-in-one connectors, combined with adhesive, can resist the stress of wood expansion and contraction. For furniture that is frequently assembled and disassembled, quick-release hardware combined with mortise and tenon joints facilitates operation without damaging components, and is beneficial for transportation and storage.

[0003] Furniture connection structures generally include mortise and tenon joints, dovetail joints, three-in-one connectors, concealed connectors, hardware zipper connections, bolt and nut connections, and nailing. Among them, bolt and nut connections use bolts and nuts to connect furniture parts together. This connection method is relatively traditional, has high connection strength, and is suitable for some furniture with high requirements for connection strength, such as large solid wood furniture and metal furniture.

[0004] Existing bolt and nut connections tend to wobble at the furniture joints after prolonged use. Traditional connections rely solely on a single bolt and nut, leading to bolt wear, nut detachment, and ultimately, furniture joints that easily detach due to excessive wobbling. Therefore, a furniture connection structure with multiple fixing functions is proposed to solve these problems. Utility Model Content

[0025] Reference Figure 1 - Figure 4 This utility model provides an embodiment of a furniture connection structure with multiple fixing functions, including a crossbeam 1, which is a lateral support component of the furniture frame and provides an installation base for other components. A locking block 2 is fixedly connected to one side of the outer wall of the crossbeam 1. The locking block 2 is used to cooperate with other components to achieve connection and positioning. An extension plate 4 is slidably connected to the outer wall of the locking block 2. The extension plate 4 can increase the length of the crossbeam 1 to accommodate furniture of different sizes. The outer wall of the extension plate 4 is slidably connected inside the crossbeam 1. This design makes the connection between the extension plate 4 and the crossbeam 1 more stable. A [missing information - likely a design element] is provided on one side of the outer wall of the crossbeam 1 and the vertical beam 3.

L-shaped corner bracket 2-9 is installed on the other side of the outer wall of the horizontal beam 1 and the vertical beam 3. L-shaped corner bracket 2-9 works together with L-shaped corner bracket 1-5 to make the connection between the horizontal beam 1 and the vertical beam 3 more secure. Connecting components for connecting L-shaped corner bracket 1-5 and L-shaped corner bracket 2-9 are installed inside the horizontal beam 1 and the vertical beam 3 to ensure a stable connection of the corner brackets within the beams. Adjustment components for adjusting the distance between L-shaped corner bracket 1-5 and L-shaped corner bracket 2-9 are installed on the outer wall of L-shaped corner bracket 1-5, allowing for adjustment of the distance according to actual needs, making the connection more precise.

[0026] The adjustment assembly includes a mounting plate 6, which provides mounting positions for other adjustment components. One side of the outer wall of the mounting plate 6 is fixedly connected to one side of the outer wall of the L-shaped bracket 5. A limiting groove 7 is formed through the interior of the mounting plate 6 to restrict the movement direction of other components. A positioning seat 8 is fixedly connected to one side of the outer wall of the mounting plate 6, supporting and positioning the lead screw 12. A slider 10 is fixedly connected to one side of the outer wall of the L-shaped bracket 9, allowing the slider 10 to slide on the mounting plate 6 for spacing adjustment. A threaded sleeve 11 is fixedly connected to one side of the outer wall of the slider 10, engaging with the lead screw 12 to achieve the adjustment function. The lead screw 12 is rotatably connected to one side of the interior of the positioning seat 8, allowing the lead screw 12 to push the threaded sleeve 11 by rotation. The distance between L-shaped bracket 15 and L-shaped bracket 29 is adjusted by moving the screw 12. The screw 12 is threaded inside the threaded sleeve 11. The adjusting assembly includes bolt 14, which passes through the vertical beam 3, L-shaped bracket 15 and L-shaped bracket 29 to further tighten them. Bolt 25 is installed inside the crossbeam 1, extension plate 4, L-shaped bracket 15 and L-shaped bracket 29. Bolt 25 also serves to tighten the connection. Washers 16 are fitted on the outer walls of bolt 14 and bolt 215. Washers 16 can increase the contact area, distribute pressure, and make the connection more stable. Fastening nuts 17 are threaded on the outer walls of bolt 14 and bolt 215. Fastening nuts 17 are used to tighten the bolts to make the various components tightly connected.

[0027] Reference Figure 1 - Figure 4Both L-shaped corner bracket 5 and L-shaped corner bracket 9 have symmetrical extension blocks 23 fixedly connected to their outer walls. These extension blocks 23 increase the length of the corner brackets, providing more space and a more stable connection base for subsequent installation of other components. A positioning block 18 is provided between the two extension blocks 23 to determine the position and provide an accurate reference point for the installation of other related components. A hinge seat 19 is fixedly connected to the outer wall of the positioning block 18. The hinge seat 19 serves as the installation base for the stabilizing components, ensuring their normal installation and rotation. The stabilizing crossbeam 1 and vertical beam 3 are installed inside the hinge seat 19. The stabilizing component enhances the stability of the connection between the crossbeam 1 and the vertical beam 3, reducing swaying. The stabilizing component includes a hinge block 20, which can rotate flexibly within the hinge seat 19, allowing the stabilizing component to better adapt to different stress conditions and effectively exert its stabilizing effect. One side of the outer wall of the hinge block 20 is rotatably connected to the interior of the hinge seat 19. A bolt 21 is fixedly connected to one side of the outer wall of the hinge seat 19. Bolt 21 provides an installation point and rotation axis for the long nut 22, allowing the long nut 22 to rotate around it. The long nut 22 is rotatably connected to the outer wall of bolt 21, and the long nut 22 can be rotated... The position is adjusted to change the state of the stabilizing components, thereby adjusting the stabilizing effect of the crossbeam 1 and the vertical beam 3. The outer wall of the slider 10 is slidably connected to the inner wall of the limiting groove 7. The limiting groove 7 is used to limit the movement of the L-shaped angle bracket 2 9, ensuring that the L-shaped angle bracket 2 9 moves within a predetermined direction and range, guaranteeing the accuracy and stability of the adjustment, and preventing it from deviating from the track during movement and affecting the adjustment effect. A knob 13 is fixedly connected to one side of the outer wall of the lead screw 12. The knob 13 allows the user to easily rotate the lead screw 12. The user can easily apply torque to the lead screw 12 by rotating the knob 13, making the operation... More convenient, without the need for additional tools, the outer wall of the gasket 16 is attached to the outer wall of L-shaped corner bracket 15 and L-shaped corner bracket 29. The gasket 16 is used to increase the contact area of ​​the fastening nut 17, which can disperse the pressure generated when the fastening nut 17 is tightened, prevent indentations or damage on the corner bracket surface, and make the connection more stable and reliable. The extension plate 4 has a positioning hole through it. The positioning hole is used to position the bolt 2 15 connected to the crossbeam 1. It can accurately determine the relative position of the extension plate 4 and the crossbeam 1, ensuring the accuracy and firmness of the connection between the two, and preventing the extension plate 4 from shifting during use.

[0028] Working principle: When using this connection structure to connect the crossbeam 1 and vertical beam 3 of furniture, the extension plate 4 is inserted into the crossbeam 1, and L-shaped brackets 1-5 and 2-9 are simultaneously attached to the outer wall of the vertical beam 3. Then, the positioning block 18 is placed between the extension blocks 23. Rotating the knob 13 causes the lead screw 12 to rotate. As the lead screw 12 moves within the positioning seat 8, it drives the slider 10 on one side of the threaded sleeve 11 to slide within the limiting groove 7. Then, by bringing the L-shaped brackets 1-5 and 2-9 closer together, the positioning block 18 is fixed. This also allows for connection between the crossbeam 1 and vertical beam 3. The thickness is adjusted to achieve the desired locking effect. Then, by rotating two bolts 21 and connecting them with long nuts 22, the crossbeam 1 and vertical beam 3 are fixed and supported, thus achieving initial stability. Then, by inserting bolt 14 into the vertical beam 3, bolt 25 is inserted through the extension plate 4 to prevent the vertical beam 3 from falling off. Then, by inserting bolt 14 through the vertical beam 3, L-shaped bracket 15, and L-shaped bracket 29, further stabilization is achieved. Finally, by tightening the fastening nut 17 on the outer wall of bolt 14 and bolt 25, the crossbeam 1 and vertical beam 3 are further fixed.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
