[0025] This utility model provides, for example Figure 1 - Figure 4 The sofa bed shown includes a sofa frame 1 and a sofa back panel 2 rotatably disposed at the end of the sofa frame 1. The sofa frame 1 is a commonly used frame for existing sofa beds, and its material is metal, which is existing technology and will not be described in detail here. The sofa back panel 2 is the sofa backrest of the sofa, which is rotatably disposed and connected to the sofa frame 1, so that the sofa back panel 2 can be placed flat or tilted, which is existing technology and will not be described in detail here.

[0026] The sofa frame 1 has a sliding cavity 4 at one end, and the sliding cavity 4 has a convex cross-section. A sliding frame 5 is movably installed inside the sliding cavity 4. The sliding frame 5 can extend and retract within the sliding cavity 4. The use of the sofa bed can be quickly changed by the setting of the sliding frame 5. Two sliding legs 6 are fixed at the lower end of the sliding frame 5. The sliding legs 6 are used to support the sliding frame 5 and facilitate the use of the sliding frame 5. A limiting strip 11 is fixed at the end of the sliding frame 5. The length of the limiting strip 11 is equal to the length of the sliding cavity 4. By setting the shape of the sliding cavity 4 and the setting of the limiting strip 11, the sliding frame 5 can be prevented from running out of the sliding cavity 4 when in use. Multiple frame legs 3 are fixed at the lower end of the sofa frame 1.

[0027] Depending on the usage status of the sofa bed, the user can choose to push back or pull out the push-pull frame 5. The push-pull frame 5 drives the limit strip 11 to move, and the limit strip 11 moves inside the push-pull cavity 4.
