Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent laws within the scope of the claims of the present invention.

Example 1: as shown in fig. 1 to 4, a sofa convenient for assembly and disassembly includes a sofa body 1 and armrests 2, wherein the armrests 2 are installed on both sides of the sofa body 1. The sofa body 1 and the armrest 2 are assembled and connected through the connecting assembly, the connecting assembly comprises an inserting unit 3 and a locking unit 4, and the inserting unit 3 and the locking unit 4 are respectively arranged on two adjacent side faces of the armrest 2 and the sofa body 1. If the inserting unit 3 is arranged on the armrest 2, the locking unit 4 is arranged on the sofa body 1; or the inserting unit 3 is installed on the sofa body 1 and the locking unit 4 is installed on the armrest 2. In the present embodiment, as shown in fig. 1 and 2, the inserting unit 3 is mounted on the armrest 2, and the locking unit 4 is mounted on the sofa body 1.

The inserting unit 3 is a horizontally arranged rod body, and a latch 301 is arranged on the rod body. One side of handrail 2 towards sofa body 1 is provided with mounting panel 6, and grafting unit 3 detachably installs on mounting panel 6, if adopt bolt and nut to fix on the mounting panel, and grafting unit 3 is dismantled to the convenience in the packing process, reduces the packing volume.

The locking unit 4 includes a socket 401 and an engaging piece 402, and the engaging piece 402 is mounted in a mounting groove of an inner wall of the socket 401. One end of the engaging member 402 is hinged in the insertion hole 401 by a hinge shaft, and one end facing the armrest can swing relatively. The structure of the engaging member 402 is similar to that of the plug-in unit 3, and the engaging member 402 is also provided with a latch 301. The latch 301 is respectively distributed on the plug-in unit 3 and the engaging member 402 at intervals along the plug-in direction (i.e. the length direction of the rod body), and a slot for engaging with the latch 301 is formed between two adjacent latches 301. The latch 301 of the plug-in unit 3 is latched in the latch groove of the engaging piece 402, and the latch 301 of the engaging piece 402 is latched in the latch groove of the plug-in unit 3. After the plug unit 3 is inserted into the insertion hole 401, the plug unit 3 and the engaging member 402 are engaged with each other by the engaging teeth 301, so as to lock the plug unit 3 and the locking unit 4.

The sofa body 1 is provided with an unlocking unit 5 for driving the engaging piece 402 to move in a direction away from the plug-in unit 3. The unlocking unit 5 comprises a handle 501 and a connecting piece 502, the handle 501 is hinged on the sofa body 1, the connecting piece 502 is connected between the handle 501 and the clamping piece 402, and the connecting piece 502 is a steel wire rope. When the handle 501 is rotated, the connecting member 502 is pulled by leverage to drive the engaging member 402 to move, so that the engaging member 402 is separated from the unlocking unit 5, and at this time, the sofa body 1 and the armrest 2 are in an unlocked state, so that the armrest 2 can be detached.

The hinge shaft is provided with a torsion spring for driving the clamping piece 402 to approach the inserting unit 3, the torsion spring is sleeved on the hinge shaft, one end of the torsion spring is fixed on the inner wall of the inserting hole 401, and the other end of the torsion spring is fixed on the hinge shaft. When the inserting unit 3 is inserted into the inserting hole 401, the handle 501 is released, the engaging member 402 swings toward the direction close to the inserting unit 3 under the torsion of the torsion spring, so that the engaging member 402 is engaged with the inserting unit 3, and at this time, the sofa body 1 and the armrest 2 are in the locking state, thereby completing the installation of the armrest and the sofa body 1.

Example 2: as shown in fig. 5, the difference from embodiment 1 is that a sliding groove is provided on the inner wall of the insertion hole 401, both ends of the engaging member 402 are slidably mounted in the sliding groove, and when the handle 501 is rotated, the connecting member 502 is pulled by leverage, and the engaging member 402 moves away from the plug unit 3, so that the engaging member 402 is separated from the plug unit 3. A return spring 403 is arranged between the engaging member 402 and the inner wall of the insertion hole 401, and when the handle 501 is released, the elastic force of the return spring 403 pushes the driving engaging member 402 to move toward the insertion unit 3, so that the engaging member 402 and the insertion unit are engaged and locked.

In the above embodiment, the handle 501 may be replaced with a button, that is, the plugging unit 3 is unlocked from the catch 402 after the button is pressed; when the push button is released, the push button is reset by the spring, and the plug unit 3 is locked with the engaging piece 402.
