[0033] Please refer to Figures 1 to 6 The embodiment provides a furniture connecting structure, and the furniture at least comprises a first plate and a second plate, the connecting structure comprises a screw rod 10 and a fastener 20; the screw rod 10 is provided with a threaded portion 11 and a nut portion 12 at two ends respectively, the threaded portion 11 is used for being connected on the first plate; the fastener 20 is provided with a mounting thread 21 on the outer peripheral wall, the mounting thread 21 is used for being connected on the second plate; the fastener 20 is rotatably provided with a clamping seat sleeve 30 in the inside, the upper end face of the fastener 20 is inwardly provided with a limiting piece 23, the limiting piece 23 is used for limiting the clamping seat sleeve 30 from separating from the fastener 20; the side wall of the clamping seat sleeve 30 is provided with a clamping piece 32, the side wall of the fastener 20 is provided with a matching groove, the screw rod 10 is provided with a clamping ring 13, the nut portion 12 of the screw rod 10 passes through the fastener 20 and is inserted into the inside of the clamping seat sleeve 30, and the clamping ring 13 is clamped in the matching groove, when the clamping seat sleeve 30 is driven by external force, the clamping piece 32 can be driven to be clamped and connected with the screw rod 10.
[0034] Specifically, in the embodiment, the upper end face of the fastener 20 is inwardly provided with a limiting piece 23, the limiting piece 23 is located above the top of the clamping seat sleeve 30; the lower end face of the fastener 20 is inwardly provided with a limiting base, the limiting base is located below the bottom of the clamping seat sleeve 30, and the limiting base and the limiting piece 23 jointly form a limiting structure of the clamping seat sleeve 30, and the limiting structure is used for preventing the clamping seat sleeve 30 from separating from the inside of the fastener 20.
[0035] Wherein, the fastener 20 of the embodiment can be, but is not limited to, a tubular structure with two open ends. For example, the limiting piece 23 can be an arc-shaped structure formed by inwardly bending the upper end face of the fastener 20, so as to prevent the clamping seat sleeve 30 from separating from the upper end of the fastener 20.
[0036] Optionally, the matching groove of the embodiment is a U-shaped groove structure, the side wall of the matching groove is provided with a U-shaped clamping groove 22, and the clamping ring 13 is inserted into the U-shaped clamping groove 22 from the opening of the U-shaped clamping groove 22. Further, the width of the two sides of the U-shaped clamping groove 22 is sequentially contracted from the opening end of the U-shaped clamping groove 22 to the bottom of the U-shaped clamping groove 22.
[0037] Furthermore, in this embodiment, the side wall of the card holder sleeve 30 is provided with a through hole 31. The nut portion 12 of the screw 10 passes through the mating groove and the through hole 31 in sequence and extends into the interior of the card holder sleeve 30. The retaining ring 13 is inserted into the U-shaped retaining groove 22 from the opening of the U-shaped retaining groove 22. In addition, the engaging member 32 is a C-shaped engaging groove, which is provided together with the through hole 31. When the card holder sleeve 30 is driven by an external force, it can drive the C-shaped engaging groove to engage with the screw 10.
[0038] To facilitate rotation of the retaining sleeve 30, both the upper and lower end faces of the retaining sleeve 30 in this embodiment are provided with slotted or Phillips head slots. Therefore, the retaining sleeve 30 in this embodiment can be driven to rotate using a screwdriver. Similarly, the nut portion 12 in this embodiment is provided with slotted or Phillips head slots.
[0039] like Figure 6 As shown, in use, the connection structure of this embodiment first tightens the screw 10 into the preset mounting hole of the first plate to fix the screw 10 on the first plate; then tightens the fastener 20 into the preset mounting hole of the second plate, so that the mating groove of the fastener 20 is aligned with the nut 12 of the screw 10; then inserts the screw 10 into the inside of the card holder sleeve 30 and makes the retaining ring 13 of the screw 10 clamp in the U-shaped groove 22 of the fastener 20; finally, by rotating the card holder sleeve 30, the C-shaped engagement groove of the card holder sleeve 30 is engaged with the screw 10, thereby fixing the screw 10 and the fastener 20 together, and successfully splicing and fixing the first plate and the second plate together.
[0040] Traditional plastic retainer sleeves not only have limited load-bearing capacity but also tend to detach from fasteners. In contrast, this embodiment innovatively uses zinc alloy to construct the retainer sleeve 30, significantly improving its load-bearing capacity. Simultaneously, a limiting member 23 (also made of zinc alloy) is precisely embedded in the upper surface of the fastener 20, effectively locking the retainer sleeve 30 in place, preventing accidental detachment, and ensuring structural stability.
[0041] In addition, the design also incorporates a unique screw fastening mechanism: the screw 10 is securely connected to the fastener 20 by means of the snap ring 13, and the snap sleeve 30 has a built-in engagement element 32 that tightly engages the protruding screw 10, forming a double locking effect, not only enhancing the connection tightness between the screw and the fastener, but also greatly reducing the risk of loosening, thereby significantly improving the stability and durability of the overall connection structure and furniture. That is, the tightening effect of the snap ring 13 and the engagement of the engagement element 32 of the snap sleeve 30 form a tight and stable connection system. This design effectively prevents the screw from loosening and falling off during use, ensuring the durability and stability of the connection, further improving the durability of the product. This design reduces the need for maintenance and replacement due to loose or missing parts, thereby extending the service life of the product.
[0042] The design exhibits excellent performance in terms of durability. First of all, the choice of zinc alloy material is the key to improving durability. Zinc alloy not only has high mechanical strength and hardness, but also has good corrosion resistance and wear resistance, which makes the snap sleeve 30 maintain stable performance and structural integrity even in long-term use or harsh environments, and is not prone to deformation or damage.
[0043] Compared with the traditional technology, after the installation of the two plates, the furniture connecting structure of the utility model, the screw 10 and the fastener 20 made of zinc alloy material can replace the traditional plastic shell after installation, not only making the appearance elegant, but also greatly improving the load-bearing capacity, effectively improving the appearance and stability of the plate after installation. Specifically, in the furniture connecting structure of the utility model, the snap sleeve 30 and the limiting piece 23 are made of zinc alloy material, so that the strength of the snap sleeve 30 and the limiting piece 23 made of zinc alloy is sufficient enough to greatly improve the load-bearing capacity of the snap sleeve 30 and the limiting piece 23. In this way, the screw 10 is clamped with the fastener 20 through the snap ring 13, and is further engaged with the screw 10 protruding into the fastener 20 under the engagement of the engagement element 32 of the snap sleeve 30, which can greatly strengthen the stability of the connection between the screw 10 and the fastener 20, to ensure the compact and firm connection between them, and prevent them from falling off, so that the overall structure of the two plates after installation is more compact.
[0044] The above-described embodiments only express several embodiments of the utility model, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the utility model furniture connecting structure. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the utility model, some modifications and improvements can be made, which belong to the protection scope of the utility model.
