Description

Technical Field

[0001] This utility model relates to a furniture connecting device for connecting two components in furniture, and belongs to the technical field of furniture manufacturing. Background Technology

[0002] In existing furniture, especially furniture such as desks, threaded fasteners are often used to connect two components together, including the legs. However, using threaded fasteners requires holes to be drilled in the legs of the furniture, and once the position of the holes is fixed, the relative position between the support frame and the legs is also fixed. Currently, however, there is a greater demand for more flexible assembly of office furniture, and a greater need for easier on-site assembly.

[0003] Therefore, CN110645246B discloses a fastening mechanism that uses a surrounding part to fit onto the outer surface of the leg, inserts an actuating tensioning device between two opposing engaging pieces, and causes the protrusion to engage in the hole. A tool is used to actuate a screw, the actuating end of which protrudes from the main body and acts on the locking member. The actuating tensioning device, through the cooperation of the hole and the protrusion, causes the engaging pieces to further protrude from the groove of the locking member in the opposite direction of the applied force, thereby tightly locking the clamp onto the outer surface of the leg. This method eliminates the need to drill holes for screws in the furniture legs, allowing the support frame to be fixed to the legs, and the height can be freely adjusted, making the furniture more aesthetically pleasing and the entire assembly process convenient and flexible.

[0004] However, in this utility model patent, the connection between the clamp and the actuation tensioning device is achieved through a hole and a protrusion. In production, the precision requirements for this hole and protrusion are very high. Otherwise, they will either not fit tightly or fit too tightly and be difficult to disassemble, resulting in a high scrap rate and high process cost. For products that cannot fit tightly or fit too tightly, this leads to inconvenience in use and reduces the product's reputation among consumers.

[0005] Based on this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0014] The present invention will be further described below with reference to specific embodiments, but the scope of protection of the present invention is not limited thereto.

[0015] like Figure 1-9 As shown, the furniture connecting device of this utility model includes an elastic member 1, a fixing member 2, and a sliding member 3 that are interconnected. Both ends of the elastic member 1 are provided with connecting pieces 11. The fixing member 2 is provided with a first connecting groove 21, and the sliding member 3 is provided with a second connecting groove 31. The connecting pieces 11 are provided with a first connecting hole 12, and the sliding member 3 is provided with a second connecting hole 32. The connecting pieces 11 are inserted into the first connecting groove 21 to achieve connection with the fixing member 2, and the connecting pieces 11 are inserted into the second connecting groove 31. Both connecting hole 12 and connecting hole 32 are through round holes with a diameter slightly larger than that of screw 4. Screw 4 passes through connecting hole 32 and connecting hole 12 to connect the mating piece 11 and the sliding piece 3.

[0016] Preferably, to achieve connection stability, this utility model uses four connecting pieces 11. Two connecting pieces 11 are respectively provided at both ends of the elastic member 1, and the two connecting pieces 11 are arranged in parallel. There are also four connecting grooves 21 and 31. The four connecting pieces 11 are inserted into the corresponding connecting grooves. The side of the fixing member 2 that is close to the sliding member 3 is provided with a protrusion 23 and a groove 24. The side of the sliding member 3 that is close to the fixing member 2 is provided with a protrusion 34 and a groove 35. During connection, the protrusion 23 is inserted into the groove 35, and the protrusion 34 is inserted into the groove 24. This is used to position and guide the sliding member 3 during the tightening process of the elastic member 1.

[0017] More preferably, the sliding member 3 of this invention has a through hole 33 with internal threads in the middle, and the end of the fixing member 2 has an abutment hole 22. After installation, the abutment hole 22 is located behind the through hole 33 and is used to block the set screw 5. The abutment hole 22 is located inside the four engagement grooves 21, and the through hole 33 is located inside the four engagement grooves 31, making it easier to tighten the set screw 5 with a wrench during installation and disassembly.

[0018] The method of using this utility model includes the following steps: (1) Insert the connecting piece 11 into the connecting groove 21 and the connecting groove 31. At this time, two connecting pieces 11 are connected to both sides of the fixing piece 2 and the sliding piece 3. Insert the protrusion 23 into the groove 35 and the protrusion 34 into the groove 24. In the subsequent steps, the elastic piece 1 will be positioned and guided during the tightening process. (2) Use the screw 4 to pass through the connecting hole 32 and the connecting hole 12 to fix the connecting piece 1 and the sliding piece 3. (3) Put the device assembled in step (2) into the leg 7 of the furniture. (4) Insert the set screw 5 into the through hole 33 and abut against the abutment hole 22. Tighten the set screw 5 with the wrench 6. Since the through hole 33 is located in the middle of the connecting groove 31 and the abutment hole 22 is located in the middle of the connecting groove 21, the sliding piece 3 will drive the elastic piece 1 to move outward smoothly until the elastic piece 1 contracts and clamps the leg 7 of the furniture until it no longer slides. When disassembly is required, simply turn the set screw 5 in the reverse direction.

[0019] In this utility model, the elastic sheet 1 is a clamping hoop, which is made of elastic thin steel plate bent into the required shape, such as square, rectangle, triangle, etc., as long as it can match the shape of the furniture leg 7.

[0020] The above embodiments are only used to explain the inventive concept of this utility model, and are not intended to limit the protection of this utility model.
