[0019] The utility model is further described in detail below based on the accompanying drawings and implementation cases.

[0020] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0021] refer to Figures 1 to 6 , the utility model embodiment discloses:

[0022] A sofa armrest structure comprises an armrest front plate 1, an armrest back plate 2 arranged opposite to the armrest front plate 1, and a connecting rod 3 arranged between the armrest front plate 1 and the armrest back plate 2, the connecting rod 3 is provided with mounting seats 4 at both ends, a clamping groove 5 is provided on the mounting seat 4, a first clamping terminal 6 is provided at the lower end of the armrest front plate 1 / the armrest back plate 2, and second clamping terminals 7 are provided at both ends of the connecting rod 3, the first clamping terminal 6 and the second clamping terminal 7 resist each other so as to be clamped into the clamping groove 5 together; the first clamping terminal and the second clamping terminal resist each other and are clamped into the clamping groove together, so as to fix the armrest front plate and the armrest back plate, that is, in the assembly process of the armrest front plate and the armrest back plate, it is no longer necessary to install fasteners in advance (after the armrest is assembled as a whole, the fasteners are uniformly installed for reinforcement), the assembly method is simple, and thus the assembly efficiency is improved.

[0023] Limited by the processing accuracy and installation method, the width of the snap-in groove 5 is usually slightly larger than the sum of the widths of the first snap-in terminal 6 and the second snap-in terminal 7. This creates a gap between the first snap-in terminal 6 / the second snap-in terminal 7, which makes it easy to disengage. Therefore, an elastic pad 8 is arranged between the first snap-in terminal 6 and the second snap-in terminal 7. The elastic pad 8 is a rubber pad that can undergo elastic deformation. When the first snap-in terminal 6 and the second snap-in terminal 7 are snapped into the snap-in groove 5, they are squeezed and deformed, so that the first snap-in terminal 6 and the second snap-in terminal 7 are more closely matched with the snap-in groove 5, thereby preventing the first snap-in terminal 6 and the second snap-in terminal 7 from loosening.

[0024] In this embodiment, it also includes a connecting frame 9 arranged between the armrest front plate 1 and the armrest rear plate 2, the connecting frame 9 includes a group of vertical insertion rods with a preset spacing, and a transverse connecting rod arranged between the group of vertical insertion rods, wherein the transverse connecting rod is used to install a connecting piece for connecting the sofa seat frame; in addition, an installation structure is provided on the mounting seat 4, and the installation structure is used to install the connecting frame 9 to fix the connecting frame 9 between the armrest front plate 1 and the armrest rear plate 2.

[0025] The mounting structure includes a mounting platform 10 arranged on the mounting seat 4, and a reinforcing rod 11 arranged on the mounting seat 4 and located on a side of the mounting platform 10 away from the connecting rod 3. A preset spacing is provided between the mounting platform 10 and the armrest front plate 1 / armrest rear plate 2. A mounting groove 12 is formed between the mounting platform 10 and the reinforcing rod 11, the connecting rod 3, and the armrest front plate 1 / armrest rear plate 2. The mounting groove 12 can be used for the lower end of the connecting frame 9 to be inserted along a predetermined direction. During the assembly process, the lower end of the vertical insertion rod is directly inserted into the mounting groove 12 to fix the connecting frame 9. The assembly method is simple and convenient, which is convenient for subsequent connection of fasteners.

[0026] A connecting block 13 is provided on one side of the reinforcing rod 11, and a connecting groove 14 is provided on one side of the mounting platform 10 for the connecting block 13 to slide in / out along a predetermined direction; specifically, in the present utility model patent, it slides in / out from top to bottom, and an anti-slip end is provided at the end of the connecting block 13, which cooperates with the connecting groove to limit the reinforcing rod 11 from sliding off the mounting platform 10 in the front-back / left-right direction.

[0027] In addition, in this embodiment, two ends of the reinforcing rod 11 resist the armrest front plate 1 and the armrest rear plate 2 respectively.

[0028] Working principle:

[0029] In this embodiment, the handrail installation process:

[0030] The first clamping end 6 and the second clamping end 7 of the armrest front plate 1 are controlled to resist each other and squeeze the elastic pad 8, so that the first clamping end 6 and the second clamping end 7 are cooperated to be clamped into the mounting seat 4 at one end of the connecting rod 3; then the first clamping end 6 and the second clamping end 7 of the armrest rear plate 2 are controlled to resist each other and squeeze the elastic pad 8, so that the first clamping end 6 and the second clamping end 7 are cooperated to be clamped into the mounting seat 4 at the other end of the connecting rod 3; that is, the armrest front plate 1 and the armrest rear plate 2 are respectively installed at the two ends of the connecting rod 3; at this time, the armrest front plate 1 and the armrest rear plate 2 are limited to maintain a preset distance, the structure is simple, and the installation is convenient.

[0031] The connecting block 13 provided on one side of the reinforcing rod 11 is controlled to slide into the connecting groove 14, so that the mounting groove 12 is formed between the mounting platform 10 and the reinforcing rod 11, the connecting rod 3, the armrest front plate 1 / armrest rear plate 2, and then the lower end of the vertical insertion rod of the connecting frame 9 is controlled to be directly inserted into the mounting groove 12, so that the assembly of the connecting frame 9 is completed; the structure is simple and the installation is convenient. Finally, the remaining components between the armrest front plate 1 and the armrest rear plate 2 are installed and fixed uniformly by fasteners, thereby improving the assembly efficiency.

[0032] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the utility model.
