Description

Technical Field

[0001] This invention relates to the field of furniture fastener technology, specifically a novel load-bearing fastener that requires no riveting. Background Technology

[0002] In the assembly process of modular wooden furniture, the ingeniously designed snap-fit ​​structure plays a key role. It can accurately and conveniently connect and reliably fix different board components, allowing ordinary users to easily and smoothly complete the rapid assembly of the entire furniture. Snap-fit ​​installation eliminates the trouble of having to equip the furniture with additional professional installation tools, significantly reducing the technical threshold and operational difficulty required for traditional furniture assembly.

[0003] Currently, common furniture snap-fit ​​designs in the industry typically require integration with matching riveting structures to achieve final fixation. This necessitates additional riveting processing of the snap-fit ​​itself during the actual assembly process, making the overall installation more complex and increasing the number of steps. Furthermore, if incorrect installation or misalignment occurs during assembly, it is difficult to disassemble and readjust, increasing rework costs and assembly difficulty. Meanwhile, existing so-called riveting-free snap-fit ​​structures on the market often have significant shortcomings in load-bearing capacity. The locking structure formed after connection is not sufficiently robust, and under prolonged load or continuous stress, it is prone to loosening, detachment, or even slippage. This seriously affects the overall structural stability and safety of the furniture after assembly, making it unsuitable for connecting and fixing furniture parts with higher strength and load-bearing requirements.

[0004] In view of this, we propose a new type of load-bearing, rivet-free buckle to solve the existing problems. Summary of the Invention

[0005] The purpose of this invention is to provide a novel load-bearing, rivet-free buckle to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a novel load-bearing, rivet-free buckle, comprising a female buckle, a fixing rod, and a male buckle, wherein the female buckle has a slot inside, and limit grooves are provided on both the front and rear sides of the slot inside the female buckle, and two sets of fixing holes are provided on the front and rear sides of the female buckle inside. A male buckle is inserted and installed on the right side of the female buckle, and two sets of insertion holes are provided on the front and rear sides of the interior of the male buckle; A fixing rod is inserted into the fixing hole and the insertion hole; Two pull rings are fixedly installed on both opposite sides of the female and male buckles.

[0007] Preferably, the slot has several hook grooves on the front and rear sides inside, and two sets of first gaskets are fixedly installed at the bottom of the female buckle.

[0008] Preferably, a rubber sleeve is fixedly installed on the side of the female buckle facing the male buckle, and one side of the rubber sleeve is in close contact with the male buckle.

[0009] Preferably, a second washer is fixedly installed at the bottom of the male buckle, and a locking tongue is fixedly installed on the side of the male buckle facing the female buckle, and the locking tongue penetrates the interior of the female buckle. Several slots are provided on the front and rear sides of the locking tongue.

[0010] Preferably, the male buckle facing the female buckle has load-bearing blocks fixedly installed on both the front and rear sides of the latch, and the load-bearing blocks are inserted into the female buckle.

[0011] Preferably, the bottom of the fixing rod is a conical structure, and a plurality of blocking rings are provided on the outer side of the fixing rod. The blocking rings are wider than the fixing rod and have a cross-sectional structure that is wider at the top and narrower at the bottom. The top of the fixing rod is wider than the fixing hole and the insertion hole.

[0012] Compared with the prior art, the beneficial effects of the present invention are: This invention inserts a fixing rod into the fixing hole and insertion hole aligned with the female and male buckles. The blocking ring on the outside of the fixing rod can be tightly engaged with the inner wall of the corresponding hole. The self-locking clamping is achieved by relying on the cross-sectional structure that is wider at the top and narrower at the bottom. The fixing connection between the female and male buckles can be completed without additional riveting work, which simplifies the overall installation process. If an installation error occurs, the fixing rod can be pulled out and disassembled for adjustment, reducing the difficulty of rework.

[0013] This invention, through the coordinated operation of the load-bearing block and the locking tongue, can distribute the vertical load on the connection part when the male and female buckles are engaged, avoiding the locking tongue from bearing the force alone. With the staggered interlocking of the hook groove and the slot, the overall load-bearing capacity and structural stability of the buckle can be greatly improved, making the buckle less prone to loosening and slippage under long-term load, thus meeting the connection and fixing requirements of heavy-duty furniture parts.

[0016] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1 - Figure 6 As shown, the present invention proposes a novel load-bearing, rivet-free buckle, comprising a female buckle 1, a fixing rod 3, and a male buckle 4. The female buckle 1 has a slot 106 inside, and limit grooves 104 are provided on both the front and rear sides of the slot 106 inside the female buckle 1. Two sets of fixing holes 101 are provided on the front and rear sides of the female buckle 1. The female buckle 1 and the male buckle 4 cooperate to connect two pieces of furniture board that need to be spliced. The slot 106 provides space for the locking tongue 402 to be inserted and installed, and the limit grooves 104 provide space for the load-bearing block 404 to be inserted and installed. The fixing holes 101 facilitate the fixing of the female buckle 1 by the fixing rod 3, so that the female buckle 1 is installed on the surface of the furniture board. The male buckle 4 is inserted and installed on the right side of the female buckle 1. The male buckle 4 has two sets of insertion holes 401 on the front and back sides inside. The insertion holes 401 can cooperate with the fixing rod 3 to install the male buckle 4 onto the surface of the furniture board, so as to facilitate cooperation with the female buckle 1 to install and splice the furniture board. A fixing rod 3 is installed inside the fixing hole 101 and the insertion hole 401. After the fixing rod 3 is inserted into the fixing hole 101 and the insertion hole 401, it can achieve self-locking through its own structure. The female buckle 1 and the male buckle 4 are respectively installed on the surface of the furniture board without the need for additional riveting processing. Two pull rings 2 are fixedly installed on both opposite sides of the female buckle 1 and the male buckle 4. The pull rings 2 can provide the operator with a force point when the buckle needs to be disassembled, so that the female buckle 1 and the male buckle 4 can be pulled out from the corresponding plate surface respectively, which is convenient for adjusting the assembly position.

[0018] Furthermore, several hook grooves 105 are provided on the front and rear sides of the interior of the slot 106. Two sets of first washers 103 are fixedly installed on the bottom of the female buckle 1. The hook grooves 105 can engage with the slots 405 on both sides of the locking tongue 402. After the locking tongue 402 is inserted into the slot 106, an interlocking limiting structure is formed, which further improves the structural stability after locking and prevents the locking tongue 402 from sliding laterally inside the slot 106. The first washers 103 can be placed between the female buckle 1 and the furniture board to fill the gap between the bottom surface of the female buckle 1 and the surface of the board after installation, so as to prevent the female buckle 1 from shaking after installation. At the same time, it can also buffer the force on the female buckle 1 and improve the structural stability.

[0019] Furthermore, a rubber sleeve 102 is fixedly installed on the side of the female buckle 1 facing the male buckle 4, and one side of the rubber sleeve 102 is in close contact with the male buckle 4. The rubber sleeve 102 can fill the reserved gap between the female buckle 1 and the male buckle 4 after installation, buffer the force transmitted from the male buckle 4 to the female buckle 1, and at the same time avoid the female buckle 1 and the male buckle 4 from directly rigidly contacting each other and causing shaking and abnormal noise, thereby improving the tightness of the structure after splicing.

[0020] Furthermore, a second washer 403 is fixedly installed at the bottom of the male buckle 4, and a locking tongue 402 is fixedly installed on the side of the male buckle 4 facing the female buckle 1, with the locking tongue 402 penetrating the interior of the female buckle 1. Several slots 405 are provided on the front and rear sides of the locking tongue 402. The second washer 403 is placed between the male buckle 4 and the installed furniture board, which can fill the installation gap between the male buckle 4 and the board, prevent the male buckle 4 from shaking after installation, and improve the installation stability. After the locking tongue 402 is inserted into the slot 106 of the female buckle 1, the slots 405 on both sides of the locking tongue 402 can interlock with the hook grooves 105 on the inside of the slot 106 to form a multi-limiting structure, preventing the locking tongue 402 from loosening from the slot 106 and improving the locking firmness.

[0021] Furthermore, load-bearing blocks 404 are fixedly installed on both the front and rear sides of the latch 402 on the side of the male buckle 4 facing the female buckle 1, and the load-bearing blocks 404 are inserted into the interior of the female buckle 1. When the plates connected by the buckle are subjected to vertical loads, the vertical force on the male buckle 4 can be transferred to the female buckle 1 through the load-bearing blocks 404, avoiding the entire load being borne by the latch 402. By distributing the force, the overall load-bearing capacity of the buckle is improved, and the latch 402 is prevented from deforming and loosening due to long-term overload.

[0022] Furthermore, the bottom of the fixing rod 3 is a conical structure, and several blocking rings are provided on the outer side of the fixing rod 3. The blocking rings are wider than the fixing rod 3, and the blocking rings have a cross-sectional structure that is wider at the top and narrower at the bottom. The top of the fixing rod 3 is wider than the fixing hole 101 and the insertion hole 401. The bottom of the conical structure can facilitate the insertion of the fixing rod 3 into the aligned fixing hole 101 and insertion hole 401, reducing the resistance to insertion. When the fixing rod 3 is inserted into the hole, the blocking ring that is wider at the top and narrower at the bottom will be squeezed and locked by the inner wall of the hole. When the fixing rod 3 is pulled outward, the blocking ring will lock more tightly with the inner wall of the hole, thereby achieving self-locking fixation without riveting. The wider top structure can prevent the fixing rod 3 from being completely embedded in the hole, and at the same time provide limiting support for the fixing rod 3 to ensure the stability of the fixation.

[0023] Working principle: Before installation, place the female buckle 1 and male buckle 4 in the preset installation positions on the two boards to be spliced, so that the fixing hole 101 is aligned with the preset installation hole on the board. Then, insert the fixing rod 3 into the fixing hole 101 and the installation hole of the board in sequence. During the insertion of the fixing rod 3, the outer side of the blocking ring, which is wider at the top and narrower at the bottom, will engage with the inner wall of the installation hole and lock itself. The female buckle 1 and male buckle 4 can be fixed to the surface of the two boards without riveting. After securing the female buckle 1 and male buckle 4, push the two boards together so that the locking tongue 402 of the male buckle 4 is inserted into the slot 106 of the female buckle 1. At the same time, the load-bearing block 404 is inserted into the limiting groove 104 of the female buckle 1. During the process of the locking tongue 402 being inserted into the slot 106, the slot 405 on the outside of the locking tongue 402 will gradually interlock with the hook groove 105 on the inside of the slot 106 to limit and prevent the locking tongue 402 from falling off. Meanwhile, after the load-bearing block 404 enters the limiting groove 104, it can form a force-sharing synergy with the female buckle 1. When the assembled furniture is subjected to load for a long time, the vertical force will be borne by the locking tongue 402 and the load-bearing block 404 together, avoiding the locking tongue 402 from being overloaded alone and improving the overall load-bearing capacity. The self-locking structure of the fixing rod 3, combined with the engagement of the hook groove 105 and the slot 405, and the distributed force of the load-bearing block 404, not only achieves convenient installation without rivets, but also ensures the overall structural stability and load-bearing capacity of the buckle. When it is necessary to adjust the assembly position, the female buckle 1 and male buckle 4 can be pulled outward by applying force through the pull ring 2, and the fixing rod 3 can be pulled out to complete the disassembly. After adjustment, it can be reinstalled, which greatly reduces the difficulty of rework and adjustment.
