[0004] The utility model solves its technical problem by adopting the following technical solutions:

[0005] A multifunctional foldable sofa chair includes a sofa chair, and an idle floating pulley is arranged in the supporting feet of the sofa chair. When the sofa chair is not occupied by people or not loaded with heavy objects, the sofa chair can be lifted up, thus facilitating movement.

[0006] Preferably, a sliding groove is arranged inside the supporting feet of the sofa chair, and a sliding frame is slidably arranged up and down in the sliding groove. A universal wheel is fixedly arranged on the lower end surface of the sliding frame by bolts.

[0007] Preferably, a reinforcing support block is fixedly arranged on the upper end surface of the sliding frame to abut against the outer end surface of the sliding groove to strengthen the connection and bearing strength of the sliding frame.

[0008] Preferably, a sliding rod is fixedly arranged at the sliding end of the sliding frame, a spring is sleeved on the sliding rod, and the upper end of the spring abuts against the inner top wall of the sliding groove.

[0009] Preferably, a jack is arranged on the sofa chair for the sliding rod to pass through, and a stroke adjustment nut is threadedly connected to the upper end of the sliding rod. By adjusting the screwing-in length of the stroke adjustment nut, the up and down sliding stroke of the universal wheel can be adjusted, and thus the gap between the sofa chair and the ground when it is unloaded can be adjusted, which is convenient for adjustment according to different requirements.

[0010] Preferably, an iron inner lining plate is inserted into the sliding groove of the sofa chair, which facilitates smooth up and down sliding. A groove is arranged on the side of the sliding frame, and a lubricating sponge inlay is embedded in the groove. The gap of the lubricating sponge inlay is filled with lubricating grease, and the outer end surface of the lubricating sponge inlay abuts against the iron inner lining plate, thus effectively improving the smoothness of the up and down sliding of the sliding frame.

[0011] The advantages and positive effects of the present utility model are as follows: The load-free floating pulley structure provided at the supporting feet of the sofa chair supports the sofa chair in a load-free state, facilitating its movement quickly and conveniently. When people sit down, the spring therein will be compressed, causing the supporting legs of the sofa chair to support, which can improve the convenience of its movement while ensuring good and stable supporting performance. Brief Description of the Drawings

[0012] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0013] Figure 1 is a schematic structural diagram of the present utility model;

[0014] Figure 2 is a schematic structural diagram of the present utility model. Detailed Description of the Embodiment

[0015] The present utility model will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0016] The following will further elaborate on the embodiments of the present utility model with reference to the drawings:

[0017] As Figure 1-2 shown, a multifunctional foldable sofa chair of the present utility model includes a sofa chair 17, and a load-free floating pulley is provided inside the supporting feet of the sofa chair 17. When the sofa chair 17 is not occupied or not loaded with heavy objects, it can lift the sofa chair 17, facilitating its movement.

[0018] Preferably, a sliding groove is provided inside the supporting feet of the sofa chair 17, and a sliding frame 11 is slidably arranged up and down in the sliding groove. A universal wheel 10 is bolted and fixed to the lower end surface of the sliding frame 11.

[0019] Preferably, a reinforcing support block 12 is fixed to the upper end surface of the sliding frame 11 to abut against the outer end surface of the sliding groove to strengthen the connection and load-bearing strength of the sliding frame 11.

[0020] Preferably, a sliding rod 14 is fixed to the sliding end of the sliding frame 11, and a spring 16 is sleeved on the sliding rod 14. The upper end of the spring 16 abuts against the inner top wall of the sliding groove.

[0021] Preferably, a jack 18 is provided on the sofa chair 17 for the slide bar 14 to pass through, and a stroke adjustment nut 15 is threadedly connected to the upper end of the slide bar 14. By adjusting the screwing-in length of the stroke adjustment nut 15, the up-and-down sliding stroke of the universal wheel 10 can be adjusted, and thus the clearance between the sofa chair 17 and the ground when it is unloaded can be adjusted, which is convenient for adjustment according to different requirements.

[0022] Preferably, an iron inner lining plate is inserted in the sliding groove of the sofa chair 17, which facilitates smooth up-and-down sliding. And a groove is provided on the side of the carriage 11, and a lubricating sponge insert 13 is embedded in the groove.
