Description

Technical Field

[0001] This utility model relates to the field of wooden furniture technology, and in particular to high-strength, bend-resistant wooden furniture. Background Technology

[0002] Wooden furniture is furniture made primarily from natural wood. It features natural beauty, environmental friendliness, and durability. It mainly includes chairs, wardrobes, and tabletops, retaining the natural texture, color, and luster of the wood, making each piece unique.

[0003] However, in existing wooden furniture, when you lean against the back of a wooden chair for a long time, the backrest will bend at an angle. The stress from the bending and rebound will be unevenly concentrated in the weakest part, causing the wood to crack or the connectors to fail, affecting the bending resistance of the backrest. Therefore, high-strength bending-resistant wooden furniture is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing high-strength, bend-resistant wooden furniture.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength, bend-resistant wooden furniture, comprising a seat body and a support leg, wherein a backrest is fixedly connected to the seat body by bolts, a plurality of heat dissipation grooves are provided on one side of the backrest, a buffer structure is provided on the backrest, two snap-fit ​​grooves are provided on one side of the seat body, the two snap-fit ​​grooves are adapted to two snap-fit ​​rods on the support leg, snap-fit ​​holes are provided on the side of the two snap-fit ​​rods on the support leg that are far apart from each other, and a snap-fit ​​structure is provided on the side of the seat body that is far apart from each other; The buffer structure includes two first support frames fixedly connected to one side of the backrest. Each first support frame has a first connecting block rotatably connected inside. When the user leans back, a backward force is applied to the backrest, and the backrest pushes backward, compressing the damper piston rod through the first support frame and the first connecting block.

[0006] Two second support frames are fixedly connected to one side of the main body of the seat. Each second support frame has a second connecting block rotatably connected inside it. A damper is fixedly connected to one side of each second connecting block. The piston end of each damper is fixedly connected to one side of the corresponding first connecting block. When rebounding, the speed is controlled to allow the backrest to slowly return to its original position. The smooth movement allows the stress to be distributed more evenly throughout the bending structure and connection points, avoiding wood cracking or connector failure, and improving the bending resistance of the backrest.

[0007] The snap-fit ​​structure includes a fixed frame fixedly connected to one side of the seat body. A sliding rod is slidably connected through one side of the fixed frame. A fork handle is rotatably connected to one end of the sliding rod. One side of the fork handle is in contact with the outer side of the fixed frame. When the fork handle is moved, the fork handle drives the sliding rod to move.

[0008] The other end of the sliding rod is fixedly connected to a snap-fit ​​post. The snap-fit ​​post is slidably connected to one side of the seat body and is adapted to the corresponding snap-fit ​​hole.

[0011] The bottom of the seat body is fixedly connected to four support legs, and each support leg is fixedly connected to an anti-slip pad. The anti-slip pad increases the friction with the ground and improves the anti-slip effect.

[0012] This utility model has the following beneficial effects: 1. By setting up a first support frame, a first connecting block, a second support frame, a second connecting block, and a damper, when the user leans back, a backward force is applied to the backrest, pushing the backrest backward. The first support frame and the first connecting block compress the piston rod of the damper, causing the backrest to bend slowly and uniformly. When it rebounds, the speed is controlled to allow the backrest to slowly return to its original position. The smooth movement allows the stress to be distributed more evenly throughout the bending structure and connection points, preventing the wood from cracking or the connectors from failing, and improving the bending resistance of the backrest.

[0013] 2. By setting up a fixed frame, sliding rod, locking pin, shift fork handle, and return spring, the shift fork handle is turned, which drives the sliding rod to move. The sliding rod drives the locking pin to move, causing the locking pin to retract and compressing the return spring. Then, the support leg is inserted into the two locking slots. Then, the shift fork handle is turned again, and under the elastic reset of the return spring, the locking pin is pushed into the locking hole to lock and fix the support leg. The support leg supports the user's lower leg, improving the user's comfort. Attached Figure Description

When the shift fork handle 804 is turned, the shift fork handle 804 drives the sliding rod 802 to move, and the sliding rod 802 drives the snap-fit ​​column 803 to move, causing the snap-fit ​​column 803 to retract and compress the return spring 805. Then the support leg 6 is inserted into the two snap-fit ​​slots 5. Then the shift fork handle 804 is turned again, and under the elastic return of the return spring 805, the snap-fit ​​column 803 is pushed into the snap-fit ​​hole 7 to snap and fix the support leg 6. The support leg 6 supports the user's lower leg and improves the user's comfort.

[0018] Working principle: When the user leans back, a backward force is applied to the backrest 2, causing the backrest 2 to push backward through the first support frame 301 and the first connecting block 302. The piston rod of damper 305 is compressed, causing the backrest 2 to bend slowly and uniformly. During the rebound, the speed is controlled to allow the backrest 2 to slowly return to its original position. The smooth movement allows the stress to be distributed more evenly throughout the bending structure and connection points, preventing wood cracking or connector failure and improving the bending resistance of the backrest 2. The fork handle 804 is moved, which drives the sliding rod 802 to move. The sliding rod 802 drives the locking post 803 to move, causing the locking post 803 to retract and compress the return spring 805. Then, the support leg 6 is inserted into the two locking slots 5. The fork handle 804 is moved again, and under the elastic return of the return spring 805, the locking post 803 is pushed into the locking hole 7 to lock and fix the support leg 6. The support leg 6 supports the user's lower leg, improving the user's comfort.
