[0019] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0020] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0021] Reference Figure 1 and Figure 2As shown, the telescopic structure of the sofa seat is to adapt to the different requirements of different groups of people on the size of the sofa sitting space. The telescopic process is actually the process of adjusting the width of the sofa seat. The existing sofa seat width adjustment process mostly requires the use of a driving device to drive or fold and other series of adjustment processes, and the process of driving by the driving device is relatively complicated and has a long cycle. In order to solve this kind of problem, a telescopic structure of a sofa seat is proposed, including a sofa body 1 and a backrest 12 arranged on one side of the sofa body 1, a first cushion 13 is arranged in the sofa body 1, a sliding groove 14 is formed between the first cushion 13 and the sofa body 1, a telescopic member 2 is horizontally slidably arranged in the sliding groove 14, and the telescopic member 2 includes a second cushion 22 horizontally slidably arranged in the sliding groove 14, and a guide is provided in the second cushion 22 The slide groove 221, the side wall of the slide groove 14 is provided with a guide slide rod 21 that is inserted into the guide slide groove 221, the guide slide rod 21 is horizontally slidably arranged along the guide slide groove 221 to ensure the stable sliding of the second cushion 22, and the guide slide rod 21 is provided with a limiter for preventing the guide slide rod 21 from sliding over the stroke; the purpose of forming a sofa main body function can be achieved through the arrangement of the sofa body 1, the backrest 12 and the first cushion 13, and the second cushion 22 can be made to slide out relative to the first cushion 13 through the arrangement of the telescopic member 2 in the slide groove 14, thereby achieving the purpose of effectively adjusting the insufficient width of the first cushion 13, and the stability of the sliding out process of the second cushion 22 can be ensured through the arrangement of the guide slide rod 21, and the second cushion 22 can be prevented from sliding over the stroke with the arrangement of the limiter, thereby ensuring the purpose of relative stability of the entire adjustment process.

[0022] It should be noted that the purpose of adjusting the sitting width of the first seat cushion 13 can be achieved by pulling the second seat cushion 22 out of the sliding groove 14 directly below the first seat cushion 13. During the horizontal sliding of the second seat cushion 22 along the sliding groove, the guide slide rod 21 slides accordingly in the guide slide groove 221, thereby ensuring the overall sliding stability of the second seat cushion 22.

[0023] Furthermore, in order to ensure that the operator can pull out the second seat cushion 22 more conveniently, in the present embodiment, a pulling groove 222 is provided on the side surface of the second seat cushion 22 away from the sliding groove 14 for facilitating the operator to pull the second seat cushion 22; the setting of the pulling groove 222 can facilitate the operator to put his hand into the pulling groove 222, thereby achieving the pulling out of the second seat cushion 22.

[0024] It should also be noted that in order to ensure that the second seat cushion 22 does not slide over the stroke in the sliding groove 14, in this embodiment, the above requirements are achieved by setting a limit member. Specifically, the structure of the limit member is as follows: the limit member includes a limit sleeve 211 which is sleeved on the end of the guide slide rod 21 close to the second seat cushion 22, the diameter of the limit sleeve 211 is the same as the diameter of the guide slide groove 221, and the guide slide groove 221 is in an opening contraction setting on the open side; it should be noted that the guide slide groove 221 and the guide slide rod 21 are both cylindrical in shape, and the diameter of the opening of the guide slide groove 221 is smaller than the internal sliding area for the guide slide rod 21, that is, when the limit sleeve 211 cannot be separated from the guide slide groove 221, the controllable sliding of the second seat cushion 22 is guaranteed.

[0025] In addition, in order to ensure that the second seat cushion 22 is more stable after sliding out, in this embodiment, a support column 224 is provided at the bottom of the second seat cushion 22 away from the sofa body 1; the setting of the support column 224 can ensure that the second seat cushion 22 is placed horizontally after being pulled out, and cooperates with the first seat cushion 13. When the second seat cushion 22 slides out, the operator sits on the second seat cushion 22, which will also make the second seat cushion 22 in a stable setting state, and will not deviate or the like.

[0026] It is worth mentioning that in order to ensure that the sofa body 1 is better placed on the ground, in this embodiment, a plurality of supporting feet 11 for supporting the sofa body 1 are provided at the bottom of the sofa body 1; the arrangement of the supporting feet 11 can achieve the purpose of orderly arrangement of the sofa body 1.

[0027] It should be noted that since there is a certain difference in height between the first seat cushion 13 and the second seat cushion 22, in order to better improve the sitting comfort, in this embodiment, a protective seat cushion 223 is provided on the top surface of the second seat cushion 22 for facilitating people to sit; the provision of the protective seat cushion 223 can better meet the purpose of comfortable sitting of people.

[0028] In addition, the internal structure of the protective cushion 223 can be further extended. For example, the protective cushion 223 is an inflatable cushion. When the second cushion 22 is pulled out, the protective cushion 223 can be inflated to ensure that the height of the protective cushion 223 plus the second cushion 22 is consistent with the height of the first cushion 13, thereby better meeting the purpose of comfortable sitting of personnel.

[0029] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
