When the user leans on the backrest 3, the extension rod 45 will be driven to move in the direction away from the telescopic plate 5. The moving extension rod 45 will pull the sliding block 44 to move. At this time, the sliding block 44 stretches the tension spring 6, and the displaced sliding block 44 will push the first telescopic rod 43. The first telescopic rod 43 will push the rotating ring 42 to rotate. The rotating ring 42 will force the second telescopic rod 46 to rotate while rotating on the fixed column 41. The second telescopic rod 46 pushes the extension rod 47, so that the pushing block 48 on the extension rod 47 is pushed away from the backrest 3. Since the telescopic plate 5 is fixed on the pushing block 48, the telescopic plate 5 stored in the sofa is extended, which is convenient for people to place their legs.

[0018] The outer surface of the second telescopic rod 46 is fixedly connected to the outer surface of the rotating ring 42, the outer surface of the fixed column 41 is fixedly connected to the inner wall of the armrest 2, the outer surface of the backrest 3 is rotatably connected to the extension rod 45, the outer surface of the telescopic plate 5 is fixedly connected to the outer surface of the pushing block 48, the inner surface of the armrest 2 is slidably connected to the outer surface of the sliding block 44, the outer surface of the sliding block 44 is fixedly connected with a tension spring 6, the outer surface of the tension spring 6 is fixedly connected to the inner surface of the armrest 2, a toothed groove 7 is provided in the wall of the armrest 2, and a sliding groove 8 is provided in the wall of the armrest 2. When the telescopic device 4 is unfolded, the backrest 3 leans back, and the telescopic plate 5 extends forward, the teeth on the toothed groove 7 will press down the card plate 441 until the telescopic plate 5 is fully extended, the reset spring 442 lifts the card plate 441 again, and the card plate 441 and the toothed groove 7 cooperate to fix the telescopic device 4 so that the telescopic device 4 cannot be retracted. Example

[0019] See also Figure 1 - Figure 5 The utility model provides a technical solution: on the basis of the first embodiment, the inner surface of the sliding block 44 is rotatably connected with a card plate 441, the lower surface of the card plate 441 is fixedly connected with a return spring 442, the lower surface of the card plate 441 is fixedly connected with a pull rope 443, the outer surface of the pull rope 443 is slidably connected with a sliding plate 444, the outer surface of the pull rope 443 is fixedly connected with a holding block 445, the lower surface of the return spring 442 is fixedly connected to the upper surface of the sliding block 44, the outer surface of the pull rope 443 is slidably connected to the inner surface of the sliding block 44, and the sliding plate 444 is fixedly connected to the outer surface of the pull rope 443. The outer surface is slidably connected to the inner surface of the armrest 2 through the sliding groove 8, and the outer surface of the clamping plate 441 contacts the inner surface of the armrest 2 through the toothed groove 7. During the forward extension of the telescopic plate 5, the teeth on the toothed groove 7 will press down the clamping plate 441 until the telescopic plate 5 is fully extended, and the return spring 442 lifts up the clamping plate 441 again. The clamping plate 441 and the toothed groove 7 cooperate to fix the telescopic device 4 so that the telescopic device 4 cannot be retracted, thereby achieving the effect of fixing the sofa after extension, so that the user does not need to apply force to the backrest 3 all the time, which is convenient for the user to rest more comfortably.

[0020] Working principle:

[0021] When in use, a telescopic device 4 is provided. When the user leans on the backrest 3, the extension rod 45 will be driven to move in a direction away from the telescopic plate 5. The moving extension rod 45 will pull the sliding block 44 to move. At this time, the sliding block 44 stretches the tension spring 6. The displaced sliding block 44 will push the first telescopic rod 43. The first telescopic rod 43 will push the rotating ring 42 to rotate. The rotating ring 42 will force the second telescopic rod 46 to rotate while rotating on the fixed column 41. The second telescopic rod 46 pushes the extension rod 47, so that the pushing block 48 on the extension rod 47 is pushed in a direction away from the backrest 3. When the backrest 3 is not under force, the tension spring 6 stretched by the sliding block 44 will pull the sliding block 44 to the center of the armrest 2 to restore the original state. Contrary to the stretching process, the telescopic plate 5 is stored on the upper surface of the base 1 of the sofa.

[0022] The card plate 441 is arranged to be lifted up by the return spring 442 in the normal state, so that the upper surface of the card plate 441 contacts the lower surface of the toothed groove 7. When the telescopic device 4 is unfolded, the backrest 3 leans back, and the telescopic plate 5 extends forward, the teeth on the toothed groove 7 will press down the card plate 441 until the telescopic plate 5 is fully extended, and the return spring 442 lifts up the card plate 441 again. The card plate 441 and the toothed groove 7 cooperate to fix the telescopic device 4 so that the telescopic device 4 cannot be retracted. When the fixation needs to be released, since the sliding plate 444 slides in the sliding groove 8 and the pull rope 443 moves with the sliding block 44, the holding block 445 will move with the unfolding of the telescopic device 4. Grasp the holding block 445 and pull the pull rope 443. The pulled pull rope 443 will pull down the card plate 441. At this time, the telescopic device 4 is contracted to push the telescopic plate 5 to the upper surface of the base 1.

[0023] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
