Technical Field

[0001] This utility model relates to the field of furniture installation technology, specifically to quick-installation connectors. Background Technology

[0002] Furniture boards are the boards used to make furniture. Furniture boards include bed boards, cabinet boards, and cabinet door boards. Common furniture boards include particleboard, MDF, moisture-resistant board, blockboard, cedar board, multi-layer solid wood board, Australian pine board, OSB board, veneer, Malacca board, etc. Sofas, recliners, and other common furniture are made of boards and fillers installed on the boards. The boards need to be connected and fixed by connectors.

[0003] Traditional furniture is usually connected by fixed joints, which not only makes it easy to damage the furniture during handling and transportation, but also increases transportation costs due to its large size. To address this, we propose a quick-install connector that allows furniture to be disassembled and reassembled multiple times, simplifying the installation process and bringing a convenient experience to home installation. Summary of the Invention

[0004] This utility model provides a quick-connect fitting to solve the problems in the background art.

The side wall of the eccentric connector is provided with a receiving cavity, and the bottom of the receiving cavity is provided with an arc-shaped notch. The front side of the receiving cavity is provided with an insertion port, and the rear side is provided with a torsion bend, which penetrates the insertion port. The head of the connecting rod is inserted into the receiving cavity through the insertion port, and a plastic expansion sleeve is fitted on the connecting rod.

[0006] Furthermore, the outer side of the eccentric connector is provided with anti-slip teeth, and the anti-slip teeth are located around it.

[0007] Furthermore, the arc-shaped notches are evenly distributed on the bottom of the receiving cavity and are positioned near the torsional bend.

[0008] Furthermore, the head of the connecting rod is provided with a protrusion, and the torsion bend is provided with a limiting protrusion, which is located on the inner bottom surface of the torsion bend.

[0009] Furthermore, an expansion block is provided at the tail end of the connecting rod.

[0010] Furthermore, the top of the eccentric connector is provided with a screwdriver hole.

[0015] Compared with the prior art, this utility model provides a quick-connect fitting, which has the following advantages:

[0016] This quick-connector pre-installs an eccentric connector and a connecting rod on two boards. The end of the connecting rod engages with the eccentric connector. When the eccentric connector rotates, the connecting rod, which is locked in a torsion bend, moves along the bend towards the center of the connector, thereby tightening and fixing the two boards. The clicking sound produced by the contact friction between the arc-shaped latch and the protrusions increases friction, prevents loosening, and warns against over-tightening to avoid damaging related components. When the eccentric connector is turned in the opposite direction, the connecting rod can be removed, allowing the two boards to be separated. It is easy to assemble and disassemble, facilitating the adjustment or movement of furniture. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model discloses a quick-installation connector, including an eccentric connector 1 and a connecting rod 2, which are correspondingly installed on two furniture boards. A plastic expansion sleeve 3 is fitted onto the connecting rod 2. The top of the eccentric connector 1 is provided with a screwdriver hole 101, and its side wall is provided with a receiving cavity 102. The bottom of the receiving cavity 102 is provided with an arc-shaped latch 103. The front side of the receiving cavity 102 is provided with an insertion port 104, and the rear side is provided with a torque bend 105, which penetrates the insertion port 104. The rod head of the connecting rod 2 is inserted into the receiving cavity 102 through the insertion port 104. The rod head of the connecting rod 2 is provided with a protrusion 201, and the tail of the connecting rod 2 is provided with a protrusion 201. An expansion block 202 is provided, and the eccentric connector 1 and the connecting rod 2 are pre-installed on the two plates. The head end of the connecting rod 2 cooperates with the eccentric connector 1. When the eccentric connector 1 rotates, the connecting rod 2, which is stuck in the torsion bend 105, will move closer to the center of the connector along the bend, thereby tightening and fixing the two plates. When the arc-shaped bayonet 103 and the protrusion 201 come into contact and rub against each other, a clicking sound is made, which can increase friction, prevent loosening, and remind that over-tightening should be avoided to prevent damage to related parts. When the eccentric connector 1 is rotated in the opposite direction, the connecting rod 2 can be removed to separate the two plates. The disassembly and assembly are convenient, making it easy to adjust or move furniture. The plastic expansion sleeve 3 is fitted on the connecting rod 2.

[0024] Specifically, the outer side of the eccentric connector 1 is provided with anti-slip teeth 106, and the anti-slip teeth 106 are located around it.

[0025] In this embodiment, the eccentric connector 1 is embedded in the plate, and the anti-slip teeth 106 can prevent it from sliding longitudinally.

[0026] Specifically, the arc-shaped bayonet 103 is evenly distributed on the bottom of the receiving cavity 102 and is positioned near the torsional bend 105.

[0027] In this embodiment, after the eccentric connector 1 pulls the connecting rod 2 to the appropriate position, the friction between the arc-shaped bayonet 103 and the protrusion 201 can prevent them from easily moving relative to each other, thereby maintaining the connection.

[0028] Specifically, the torsion bend 105 is provided with a limiting protrusion 107, and the limiting protrusion 107 is located on the inner bottom surface of the torsion bend 105.

[0029] In this embodiment, when the eccentric connector 1 pulls the connecting rod 2 to the appropriate position, the limiting protrusion 107 engages with the rod head of the connecting rod 2, which can prevent them from easily moving relative to each other.

[0030] Specifically, the protrusions 201 are evenly distributed on the head of the connecting rod 2, and the plastic expansion sleeve 3 is inserted from the head of the connecting rod 2.

[0031] In this embodiment, the cooperation between the protrusion 201 and the arc-shaped bayonet 103 helps to provide better stability and tightness after connection. At the same time, when the two come into contact and rub against each other and make a clicking sound, it is used to indicate that the ideal tightening state has been reached, avoiding over-tightening and damage to related components.

[0032] Specifically, the plastic expansion sleeve 3 is provided with expansion openings 301, and the expansion openings 301 are evenly distributed around the plastic expansion sleeve 3.

[0033] In this embodiment, when the connecting rod 2 is tightened, the plastic expansion sleeve 3 will move to the outer peripheral surface of the expansion block 202, forming a large positive pressure, causing the expansion opening 301 on the plastic expansion sleeve 3 to open outward, so that friction is formed between the hole wall of the plate and the plastic expansion sleeve 3, thereby fixing them together.

[0034] Specifically, the outer side of the plastic expansion sleeve 3 is provided with barbs 302, and the barbs 302 are evenly distributed around the plastic expansion sleeve 3.

[0035] In this embodiment, when the connecting rod 2 is tightened and the plastic expansion sleeve 3 expands, the plastic expansion sleeve 3 rubs against the hole wall of the plate, and with the cooperation of the barbs 302, a friction self-locking is formed between the plastic expansion sleeve 3 and the hole wall of the plate, thereby firmly fixing them together.

[0036] Specifically, the outer side of the plastic expansion sleeve 3 is provided with a threaded layer 303, and the threaded layer 303 is located at the tail of the plastic expansion sleeve 3.

[0037] In this embodiment, the main reason for designing the threaded layer 303 on the plastic expansion sleeve 3 is to ensure that the expansion sleeve can be firmly fixed on the plate and can withstand a certain amount of tensile and shear forces.

[0038] In use, the eccentric connector 1 and connecting rod 2 are pre-installed on two plates (eccentric connector 1 is a circular wheel, but the center of the wheel does not coincide with the rotation point, and there is a certain eccentricity. When the eccentric connector 1 rotates around the rotation point, due to the eccentricity, the distance from each point on the eccentric connector 1 to the rotation center changes continuously during the rotation process, resulting in radial displacement). The head end of the connecting rod 2 engages with the eccentric connector 1. When the eccentric connector 1 rotates, due to the torsional bending angle 105 of its lower part deviating from the circular center, it is stuck in... The connecting rod 2 in the torsion bend 105 will gradually approach the center of the connector along the bend angle, which will gradually reduce the distance between the two plates connected to the connecting rod 2, thereby tightening the two plates and achieving a tight connection. When the arc-shaped buckle 103 and the protrusion 201 make a clicking sound, it can increase the friction, prevent loosening, and remind you to avoid over-tightening to avoid damaging the related parts. When the eccentric connector 1 is turned in the opposite direction, the connecting rod 2 can be removed to separate the two plates. It is easy to disassemble and assemble, and convenient to adjust or move furniture.

[0039] In summary, this quick-install connector pre-installs the eccentric connector 1 and the connecting rod 2 on two boards. The head of the connecting rod 2 engages with the eccentric connector 1. When the eccentric connector 1 rotates, the connecting rod 2, which is locked in the torsion bend 105, moves closer to the center of the connector along the bend, thereby tightening and fixing the two boards. When the arc-shaped latch 103 and the protrusion 201 come into contact and rub together, making a clicking sound, it increases friction, prevents loosening, and reminds users to avoid over-tightening to prevent damage to related components. When the eccentric connector 1 is rotated in the opposite direction, the connecting rod 2 can be removed, allowing the two boards to be separated. The connector is easy to assemble and disassemble, facilitating the adjustment or movement of furniture.
