They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0034] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] Please see Figure 1-5 This utility model provides a new technical solution: a telescopic and deformable sofa, including a base 1, an armrest 2 fixedly connected to the upper side of the base 1, the armrest 2 being located at the front side, a backrest 3 fixedly connected to the upper side of the base 1, the backrest 3 being located at the right side, a back cushion 4 installed on the backrest 3, a self-locking pulley 5 installed on the lower side of the base 1, a deformation plate groove 6 opened on the lower side of the base 1, the base 1 extending from the rear side of the deformation plate groove 6, three limiting grooves 7 opened on the top wall of the deformation plate groove 6, the three limiting grooves 7 being arranged left and right, a base 1 is also provided on the rear side of the base 1, the connection structure of the front and rear base 1 is the same and symmetrically arranged, a deformation mechanism is provided inside the two deformation plate grooves 6, the deformation mechanism enables the sofa to deform quickly, the deformation mechanism includes a first deformation plate 8, a second deformation plate 9, six limiting blocks 10, a connecting groove 11, a connecting block 12, a first slot 13, a second slot 14, a fixing plug 15, and a take-up and put-down groove 16.

[0036] Furthermore, the first deformable plate 8 is slidably connected to the inside of the front deformable plate groove 6, and the second deformable plate 9 is slidably connected to the inside of the rear deformable plate groove 6. Self-locking pulleys 5 are also installed on the lower sides of both the first and second deformable plates 8 and 9. Six limiting blocks 10 are respectively fixedly connected to the upper sides of the first and second deformable plates 8 and 9. Three limiting blocks 10 on the first deformable plate 8 are positioned at the front, and three limiting blocks 10 on the second deformable plate 9 are positioned at the rear. The six limiting blocks 10 are respectively adapted to six limiting grooves 7. A connecting groove 11 is opened on the front side of the second deformable plate 9, and a connecting block 12 is fixedly connected to the rear side of the first deformable plate 8. On one side, the connecting block 12 extends into the interior of the connecting groove 11. The first slot 13 is opened on the upper side of the connecting block 12, and the lower side of the first slot 13 extends through the connecting block 12. The second slot 14 is opened on the upper side of the second deformable plate 9, and the lower side of the second slot 14 extends into the interior of the connecting groove 11. The second slot 14 and the first slot 13 are opposite to each other. The fixing block 15 is slidably connected inside the first slot 13 and the second slot 14. The connecting block 12 is limited inside the connecting groove 11 by the fixing block 15. The upper side of the fixing block 15 is provided with a pick-and-place groove 16, which facilitates the disassembly and installation of the fixing block 15. The pick-and-place groove 16 is an L-shaped groove.

[0037] Furthermore, when starting the work, if the sofa needs to be deformed, the worker moves the front base 1 forward and the rear base 1 backward. As a result, the first deformation plate 8 and the second deformation plate 9 will slide out from the inside of the front and rear deformation plate grooves 6. At the same time, because the limiting block 10 is adapted to the limiting groove 7, the two bases 1 can no longer deform after sliding a certain distance. Then, the worker removes the back cushions 4 installed on the two backrests 3 and places the two back cushions 4 on the first deformation plate 8 and the second deformation plate 9. Then, the self-locking pulley 5 is self-locked, thus completing the deformation of the sofa. At this time, the self-locking pulley 5 installed on the underside of the first deformation plate 8 and the second deformation plate 9 will play a supporting role, preventing the situation where there is no support point in the middle after the sofa is stretched and deformed.

[0038] When transporting the sofa, it first needs to be disassembled. Workers simply lift the base 1 upwards, causing the deformation plate groove 6 and the limiting groove 7 on the base 1 to move upwards simultaneously. The limiting groove 7 then moves out of the limiting block 10, releasing the connection between the limiting groove 7 and the limiting block 10. This also releases the connection between the two bases 1 and the deformation mechanism. Workers then use the pick-and-place slot 16 to remove the fixing block 15. The L-shaped pick-and-place slot 16 makes removing the fixing block 15 very convenient. This also releases the limiting fixation between the connecting block 12 and the connecting groove 11, allowing the connecting block 12 to be removed from inside the connecting groove 11. This also releases the connection between the first deformation plate 8 and the second deformation plate 9. The sofa is now disassembled, allowing for the transport of its various parts, improving the convenience and efficiency of transport. After transport, the sofa parts can be reassembled using the above method.

[0039] Furthermore, this method allows for simple and quick disassembly and assembly of the sofa, thus reducing the time spent on disassembly and assembly when the sofa needs to be transported, making the transportation of the sofa more convenient.

[0040] Structural Description: Base 1, Armrests 2, Backrest 3: The main body of the sofa. Base 1 is the sitting and reclining part of the sofa, while armrests 2 and backrest 3 provide support for the arms and back, improving the user's comfort.

[0041] Back cushion 4: Back cushion 4 is a soft cotton pad, which makes it more soft and comfortable for users to lean against the backrest 3. At the same time, after the sofa is deformed, the back cushion 4 can act as a cotton pad on the first deformation plate 8 and the second deformation plate 9, so that the deformed or sofa still remains comfortable.

[0042] Self-locking pulley 5: Self-locking pulley 5 is installed on the underside of the two bases 1, the first deformable plate 8 and the second deformable plate 9 respectively. The sofa can be supported by the self-locking pulley 5, and it is also convenient to pull the two bases 1 to deform the sofa. The self-locking pulley 5 has a self-locking function to ensure the stability of the sofa during use.

[0043] Deformation plate groove 6, limiting groove 7: There are two deformation plate grooves 6, which are respectively opened on two bases 1. The two bases 1 extend from the opposite sides of the two deformation plate grooves 6. There are six limiting grooves 7. Three limiting grooves 7 are opened on the top wall of each of the two deformation plate grooves 6. The first deformation plate 8 and the second deformation plate 9 inside the deformation plate groove 6 can be limited by the six limiting grooves 7, so as to ensure that the two bases 1 can remain connected after the sofa is assembled. The limiting grooves 7 opened on the two front bases 1 do not extend out of the bases 1.

[0044] First deformation plate 8 and second deformation plate 9: the main body of the deformation mechanism. The first deformation plate 8 and the second deformation plate 9 are slidably connected inside the two deformation plate slots 6 respectively. After the two bases 1 are pulled apart, the first deformation plate 8 and the second deformation plate 9 keep the two bases 1 connected, thereby allowing the sofa to complete the deformation.

[0045] Limiting block 10: There are six limiting blocks 10. Three limiting blocks 10 are fixedly connected to the upper side of the first deformable plate 8 and the second deformable plate 9. The three limiting blocks 10 on the first deformable plate 8 are located at the front side, and the three limiting blocks 10 on the second deformable plate 9 are located at the rear side. The six limiting blocks 10 are respectively adapted to the six limiting grooves 7, thereby making the deformable mechanism and the two bases 1 connected and limited together.

[0046] Connecting groove 11 and connecting block 12: The connecting groove 11 is opened on the front side of the second deformable plate 9, and the connecting block 12 is fixedly connected to the front side of the first deformable plate 8. The connecting block 12 slides into the interior of the connecting groove 11. Through the cooperation of the connecting groove 11 and the connecting block 12, the first deformable plate 8 and the second deformable plate 9 can be connected together.

[0047] First slot 13, second slot 14, fixing block 15, and take-up slot 16: a limiting and fixing structure. The first slot 13 is opened on the upper side of the connecting block 12, and the lower side of the first slot 13 extends out of the connecting block 12. The second slot 14 is opened on the upper side of the second deformable plate 9, and the lower side of the second slot 14 extends into the interior of the connecting groove 11. The first slot 13 and the second slot 14 are opposite to each other. The fixing block 15 is slidably connected inside the first slot 13 and the second slot 14. The fixing block 15 can limit and fix the connecting block 12 inside the connecting groove 11, thereby allowing the first deformable plate 8 and the second deformable plate 9 to be connected together. The take-up slot 16 is opened on the upper side of the fixing block 15. The take-up slot 16 is an L-shaped slot, which facilitates the removal and installation of the fixing block 15 by the staff.

[0048] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
