Its frame is a chair made of wood or steel lined with cotton wadding and other foam materials. According to the shape of the sofa, currently sofas are mainly divided into two major types: classical and modern. Classical-shaped sofas generally adopt some classical shaping elements and use traditional process structures, so the structure is relatively complex.

[0003] For such sofas, the exposed parts are commonly decorated by processes such as carving, inlaying, painting, and coating. Its production process route is long and the technical requirements are high. The production process of modern-shaped sofas is relatively simple, widely using modern new process materials, with a short production process route and being convenient for large-scale production.

[0004] Existing sofas mostly use the method of foot supports to support the sofa. When moving the sofa, multiple people are needed to carry it, which is very inconvenient to move, and it is easy to cause the support structure at the bottom of the sofa to shake, affecting the service life of the sofa.

The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model

[0033] Embodiment 1:

[0034] As Figures 1 to 5As shown in the figure, this embodiment proposes a sofa that is convenient to move, including a sofa main body 1, a movable plate 2, a control component 3, a guiding mechanism 4, a limiting mechanism 5, a mounting groove 6, a control groove 7, a movable hole 10, a lifting column 11, and a universal wheel 12 connected to the lower end of the lifting column 11.

[0035] Among them, a rectangular mounting groove 6 is opened on the lower side of the outer part of the sofa main body 1. The front and rear of the inside of the mounting groove 6 are provided with rectangular movable plates 2. The front and rear movable plates 2 are respectively threadedly connected to the front and rear threads of the external part of a positive and negative thread screw rod 301 arranged inside the mounting groove 6. By rotating the positive and negative thread screw rod 301, the front and rear movable plates 2 can be driven to approach or move away from each other. Movable holes 10 are opened on both sides of the upper end of the movable plate 2. A lifting column 11 that can move up and down is arranged inside each movable hole 10. Limiting grooves 502 are opened on both sides of the lifting column 11. Limiting blocks 501 are fixedly connected to both sides inside the movable hole 10. The limiting blocks 501 are stuck inside the limiting grooves 502 to limit the up and down movement of the lifting column 11 and prevent the lifting column 11 from falling out of the inside of the movable hole 10.

[0036] A universal wheel 12 with a self-locking function is arranged at the lower end of each lifting column 11. The up and down movement of the universal wheel 12 is driven by the lifting and lowering of the lifting column 11, which is convenient for retracting the universal wheel 12 into the inside of the mounting groove 6 or extending the universal wheel 12 out of the inside of the mounting groove 6. In order to retract the universal wheel 12 into the inside of the mounting groove 6 by the mutual approach of the movable plates 2 or extend the universal wheel 12 out of the inside of the mounting groove 6 by the mutual separation of the movable plates 2, so as to realize the extension or storage of the universal wheel 12, sheep's foot-shaped pressing blocks 302 are fixedly connected to both sides of the top end inside the mounting groove 6. The lower side of the pressing block 302 is in an inverted V shape. The upper side of the lifting column 11 is a slope, which fits with the lower slope of the pressing block 302. When the movable plates 2 approach or move away from each other, the upper surface of the lifting column 11 fits with the lower slope of the pressing block 302 to realize the lifting and lowering of the lifting column 11. When it is necessary to use the sofa to ensure the stability of the sofa, the universal wheel 12 is retracted into the inside of the mounting groove 6, and the anti-slip strip 9 arranged on both sides of the lower end of the sofa main body 1 contacts the ground. When it is necessary to move the sofa, the universal wheel 12 is extended out to facilitate the movement of the sofa.

[0037] Embodiment 2:

[0038] The solution in Embodiment 1 will be further introduced below in combination with the specific working mode, as described in detail below:

[0039] In order to facilitate the control of the movable plates 2 approaching or moving away from each other, a control groove 7 is opened at the lower front side of the sofa main body 1. A controller 8 is arranged inside the control groove 7. The controller 8 is used to control the rotation direction, start and stop of the servo motor 303 installed at the lower side of the rear end outside the sofa main body 1, so as to facilitate the control of the movement of the movable plates 2.

[0040] Embodiment 3:

[0041] The solution in Embodiment 2 will be further introduced below in combination with the specific working mode. See the following description for details:

[0042] In order to ensure the smooth movement of the movable plates 2, guide rods 401 are arranged at the lower positions on both sides inside the installation groove 6. Both ends of the guide rods 401 are fixedly connected to the front and rear inside the installation groove 6 respectively. Guide holes 402 for cooperating with the guide rods 401 are opened on both sides of the front end of the movable plates 2. The movable plates 2 are sleeved outside the guide rods 401 through the guide holes 402 to ensure that the movable plates 2 can move smoothly back and forth inside the installation groove 6.

[0043] The electrical components appearing in this article are all connected to the external main controller and 220V mains. And the main controller can be a conventional known device such as a computer for control. The detailed descriptions of known functions and known components are omitted in the specific implementation manners of the present disclosure. To ensure the compatibility of the device, the operation means adopted are consistent with the parameters of market instruments.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
