[0004] However, the above sofa still has the following defects when in use: when the above existing technology is in use, since the sofa body is fixed and integrated, it is inconvenient to perform telescopic adjustment. When the sofa is not needed, the sofa is large in size, resulting in it occupying a large space, which leads to its greater limitations and lower practicality. Utility Model Content

[0005] The utility model aims to provide a telescopic sofa to solve the problem that the existing sofas proposed in the above background technology are inconvenient to be telescopically adjusted.

[0006] To achieve the above object, the utility model provides the following technical solution: a telescopic sofa, comprising a sofa body and a backrest, wherein one side of the sofa body is connected to the backrest;

[0007] An adjustment mechanism is arranged inside the sofa body, a telescopic plate is slidably arranged inside the sofa body, a guide block is fixed to the bottom end of the telescopic plate, a guide groove is arranged on the outside of the guide block, and the guide groove is opened inside the sofa body, a moving mechanism is arranged inside the sofa body on one side of the adjustment mechanism, and the bottom end of the moving mechanism is connected to a bottom plate, and both sides of the bottom end of the bottom plate are welded with walking wheels.

[0008] When a telescopic sofa of the present technical solution is used, the backrest and the telescopic plate can be easily telescopically adjusted by providing an adjustment mechanism, thereby improving its practicality.

[0009] Preferably, the moving mechanism includes an adjusting disk, and the adjusting disk is arranged inside the sofa body, one side of the adjusting disk is evenly provided with grooves, an adjusting rod is fixed to the other side of the adjusting disk, and the bottom end of the adjusting rod is sleeved with an adjusting bevel gear, one side of the adjusting bevel gear is meshed with a linkage bevel gear, a sleeve passes through the interior of the linkage bevel gear, and a screw is arranged inside the sleeve.

[0010] Preferably, a plurality of the grooves are provided, and the plurality of the grooves are distributed in a ring shape.

[0011] Preferably, the sleeve is an internal hollow structure, the interior of the sleeve is provided with an internal thread, the outer side of the screw rod is provided with an external thread, and the sleeve is threadedly connected to the screw rod.

[0012] Preferably, the adjustment mechanism includes an adjustment motor, and the adjustment motor is arranged inside the sofa body, the top end of the adjustment motor is rotatably connected to an adjustment shaft, an adjustment block is sleeved on the outer side of one end of the adjustment shaft, a driving bevel gear is sleeved on the outer side of the other end of the adjustment shaft, and a driven bevel gear is meshed on one side of the driving bevel gear, a driven shaft passes through the interior of the driven bevel gear, a moving block is sleeved on the outer side of the driven shaft, and limiting blocks are fixed on both sides of the driving bevel gear and the driven bevel gear.

[0013] Preferably, two groups of the limit blocks are provided, each group of the limit blocks is provided with two, and the cross-sections of the limit blocks in the two groups are both annular.

[0014] Preferably, the guide block slides inside the guide groove, and the telescopic plate is slidably connected to the guide groove and the sofa body through the guide block.

[0015] Preferably, the bottom of the sofa body is evenly provided with through grooves with rectangular cross-sections, and the positions of the through grooves correspond one-to-one to the running wheels, so as to be used for the upward and downward extension of the running wheels.

[0016] Compared with the prior art, the utility model has the beneficial effect that the telescopic sofa can not only be telescopically adjusted, but also is easy to move.

[0017] 1. By starting the adjusting motor, the adjusting block is driven to move upward under the action of the adjusting shaft, and the adjusting block drives the backrest to move upward synchronously at the same time. Through the above operation, the backrest is easily raised, so that the user can lie down and use it, thereby improving the comfort.

[0018] By starting the adjusting motor, the active bevel gear is driven to rotate under the action of the adjusting shaft. Since the active bevel gear and the driven bevel gear are meshed with each other, the active bevel gear rotates and drives the driven shaft to rotate synchronously, thereby driving the moving block to move horizontally. The cooperation of the guide block and the guide groove makes the telescopic plate move horizontally synchronously, thereby facilitating the telescopic plate to be pushed out from the inside of the sofa body. Through the above operation, it is convenient for the user to place his feet on the telescopic plate, thereby improving the comfort effect.

[0019] When not in use, the adjusting motor is started to drive the adjusting shaft to rotate in the opposite direction, so that the backrest and the telescopic plate can be recovered. Through the above operation, the space occupied by the backrest and the telescopic plate can be reduced, thereby improving the utilization rate of the space.

[0020] 2. By inserting a finger into the groove and turning the adjusting disk, the adjusting bevel gear is driven to rotate under the action of the adjusting rod. Since the adjusting bevel gear and the linkage bevel gear are meshed with each other, the adjusting bevel gear rotates and drives the sleeve to rotate synchronously, so that the screw rod moves downward, and then the bottom plate moves downward synchronously until the walking wheels fit against the ground, so that the sofa body can be lifted. The above operation makes it easy for the staff to move the sofa body according to the actual usage, thereby reducing the labor intensity of the staff and improving the movement efficiency.
