Description

Technical Field

[0001] This utility model belongs to the technical field of mortise and tenon connection structure, and in particular relates to a quick-release mortise and tenon connection structure for solid wood furniture for the whole house. Background Technology

[0002] The mortise and tenon structure, as the core connection method of traditional Chinese solid wood furniture, has been used to this day due to its advantages of not requiring fasteners and being compatible with the characteristics of wood. It achieves component connection through the interlocking of the tenon and mortise, and has developed into a variety of classic types according to the stress characteristics and usage scenarios.

[0003] A Chinese patent application with publication number CN206608416U discloses a mortise and tenon connection structure for solid wood furniture, including a first connecting plate and a second connecting plate. A tenon and a mortise are provided between the first connecting plate and the second connecting plate. The special feature is that the tenon includes a root neck section, a locking section and a reinforcing section connected in sequence. This utility model has a firm and tight connection, does not require glue during connection, is not only environmentally friendly, but also allows for easy disassembly and assembly.

[0004] Although the patent is detachable, it still has the disadvantage of low connection stability. In order to realize the disassembly function, a certain assembly gap must be reserved between the tenon and the mortise, which makes the connecting surface unable to fit completely. In the long term, the solid wood components are subjected to thermal expansion and contraction caused by temperature and humidity changes, vibration during daily use, and external forces such as frequent disassembly and assembly, which will gradually increase the gap and continuously reduce the interlocking degree of the tenon and the mortise, resulting in problems such as loose connection, furniture shaking, and abnormal noise.

[0005] To address these issues, we offer a quick-release mortise and tenon joint structure for all solid wood furniture. Utility Model Content

[0006] The purpose of this utility model is to provide a quick-release mortise and tenon connection structure for solid wood furniture throughout the house. Through the cooperation of vertical beams, horizontal beams and connecting components, it solves the problem that the mortise and tenon connection structure of furniture in the prior art has low connection stability and that the tenon and mortise will continuously decrease due to external force, resulting in loose connection, furniture shaking and abnormal noise.

[0029] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Please see Figure 1-8 This utility model is a quick-release mortise and tenon joint structure for solid wood furniture for the whole house. It includes a vertical beam 1, a horizontal beam 2 on one side of the vertical beam 1, and a connecting component 3 between the vertical beam 1 and the horizontal beam 2. The connecting component 3 includes a slot 301, which is opened on one side of the vertical beam 1. A block 302 is fixedly connected to one side of the horizontal beam 2. The surface of the block 302 is movably connected to the inner cavity of the slot 301. A through groove 303 is opened on one side of the inner cavity of the slot 301. An embedding groove 304 is opened on one side of the through groove 303. A side plate 305 is movably connected to the inner cavity of the embedding groove 304. An insert plate 306 is fixedly connected to one side of the side plate 305. A slot 307 is opened on one side of the block 302. The surface of the insert plate 306 is movably connected to the inner cavity of the slot 307.

[0031] Specifically: Move the crossbeam 2 closer to the vertical beam 1 until the locking block 302 on one side of the crossbeam 2 is inserted into the inner cavity of the locking slot 301 on one side of the vertical beam 1. After the locking block 302 is fully inserted into the inner cavity of the locking slot 301, move the side plate 305 so that the insert plate 306 on one side is inserted into the inner cavity of the through slot 303. Continue to push the side plate 305 so that it drives the insert plate 306 to be fully inserted into the slot 307 on the surface of the locking block 302. The insert plate 306 tightly restricts the locking block 302 in the inner cavity of the locking slot 301, thereby making the crossbeam 2 and the vertical beam 1 firmly connected together.

[0032] A reinforcing plate 4 is fixedly connected to one side of the top and bottom of the crossbeam 2. A wedge-shaped groove 5 is opened on one side of the vertical beam 1. A wedge-shaped block 6 is fixedly connected to one side of the reinforcing plate 4. The surface of the wedge-shaped block 6 is movably connected to the inner cavity of the wedge-shaped groove 5. An insertion rod is fixedly connected to one side of the inner cavity of the wedge-shaped groove 5. An insertion hole is opened on the surface of the wedge-shaped block 6. The surface of the insertion rod is movably connected to the inner cavity of the insertion hole. A clamping plate 7 is fixedly connected to one side of the inner cavity of the slot 307. A clamping groove 8 is opened on one side of the insertion plate 306. The top and bottom of the embedded groove 304 are provided with reinforcing grooves. A reinforcing block is movably connected to the inner cavity of the reinforcing groove. One side of the reinforcing block is fixedly connected to the surface of the side plate 305. A protrusion is fixedly connected to one side of the inner cavity of the reinforcing groove. A groove is provided on one side of the reinforcing block. A hook groove is provided on one side of the side plate 305. An upper hanging hole is provided at the top of the inner cavity of the hook groove. An extrusion piece is fixedly connected to the top and bottom of the inner cavity of the through groove 303. One side of the extrusion piece is in close contact with the surface of the insert plate 306.

[0033] Specifically: The wedge-shaped block 6 on one side of the reinforcing plate 4, as the crossbeam 2 connects to the vertical beam 1, is engaged in the wedge-shaped groove 5 on one side of the vertical beam 1. The reinforcing structure composed of the reinforcing plate 4, wedge-shaped block 6, and wedge-shaped groove 5 greatly improves the connection stability between the crossbeam 2 and the vertical beam 1. The insertion rod, as the wedge-shaped block 6 is engaged in the inner cavity of the wedge-shaped groove 5, is inserted into the insertion hole on the surface of the wedge-shaped block 6. The limiting structure composed of the insertion rod and the insertion hole improves the connection stability between the wedge-shaped block 6 and the wedge-shaped groove 5. When the insertion plate 306 is inserted into the inner cavity of the slot 307, the clamping groove 8 on one side of the insertion plate 306 will be engaged on the surface of the clamping plate 7. The limiting structure composed of the clamping plate 7 and the clamping groove 8 further improves the connection stability between the insertion plate 306 and the slot 307. The reinforcing block, as the side plate 305 moves, is engaged in the inner cavity of the reinforcing groove. The reinforcing block and the reinforcing groove... The limiting structure allows the side plate 305 to be more securely locked in the inner cavity of the embedding groove 304. After the reinforcing block moves and is locked into the reinforcing groove as the side plate 305 moves, the groove on one side of the reinforcing block will lock into the surface of the protrusion. The limiting structure formed by the protrusion and the groove can improve the connection stability between the reinforcing block and the reinforcing groove. Insert the opening hook into the inner cavity of the hook groove and insert the hook head into the upper hanging hole. Pull the side plate 305 with the opening hook to disengage it from the inner cavity of the embedding groove 304, thereby driving the insert plate 306 to move and disengage from the inner cavity of the slot 307 on one side of the locking block 302. As the insert plate 306 is inserted into the through groove 303, the two extrusion plates at the top and bottom of the inner cavity of the through groove 303 respectively abut against the surface of the insert plate 306. The extrusion action of the extrusion plates improves the connection stability between the insert plate 306 and the through groove 303.

[0034] The working principle of this utility model is as follows: The crossbeam 2 is moved closer to the vertical beam 1 until the locking block 302 on one side of the crossbeam 2 is inserted into the inner cavity of the locking groove 301 on one side of the vertical beam 1. Simultaneously, the reinforcing plate 4, as the crossbeam 2 presses against the vertical beam 1, comes into contact with the surface of the vertical beam 1. The wedge-shaped block 6 on one side of the reinforcing plate 4, as the crossbeam 2 connects to the vertical beam 1, is locked into the wedge-shaped groove 5 on one side of the vertical beam 1. The reinforcing structure composed of the reinforcing plate 4, the wedge-shaped block 6, and the wedge-shaped groove 5 greatly improves the connection stability between the crossbeam 2 and the vertical beam 1. After the locking block 302 is fully inserted into the inner cavity of the locking groove 301, the side plate 305 is moved so that the insert plate 306 on one side is inserted into the inner cavity of the through groove 303. The side plate 305 is continuously pushed so that the insert plate 306 is fully inserted into the slot 307 on the surface of the locking block 302. The insert plate 306 tightly restricts the locking block 302 within the locking groove. The inner cavity of 301 securely connects the crossbeam 2 and the vertical beam 1. The side plate 305 is inserted into the inner cavity of the embedding groove 304 along with the insert plate 306. After the reinforcing block moves and is inserted into the reinforcing groove along with the side plate 305, the groove on one side will be stuck on the surface of the protrusion. The limiting structure formed by the protrusion and the groove can improve the connection stability between the reinforcing block and the reinforcing groove, so that the insert plate 306 on one side of the side plate 305 is tightly inserted into the inner cavity of the slot 307 on the surface of the card block 302. When disassembly is required, insert the hook head of the opening hook into the upper hanging hole, pull the side plate 305 with the opening hook to disengage it from the inner cavity of the embedding groove 304, and then drive the insert plate 306 to move and disengage from the inner cavity of the slot 307 on one side of the card block 302. One side of the crossbeam 2 disengages the card block 302 on one side from the inner cavity of the slot 301 on one side of the vertical beam 1, and the disassembly is completed.
