[0005] By adopting the above technical solution, when using the sofa bed, first turn the limit device, and then the cushion can be rotated to multiple angles under the action of the screw rod. When it is adjusted to the appropriate angle, just let go, the limit device is inserted into the gear, the screw rod stops rotating, the cushion is fixed, the ventilation device is opened, and sitting on it will not produce sweat due to airtightness.
[0006] Specifically, the ventilation device includes a hair dryer, the bottom of the hair dryer is fixedly connected to the inner wall of the shell, the top of the support plate is fixedly connected to a steel plate, the steel plate is penetrated by a ventilation hole, and the top of the steel plate is detachably connected to a breathable sofa cushion.
[0007] By adopting the above technical solution, the hair dryer blows out cool air, passes through the ventilation holes, passes through the breathable sofa cushion, and touches people, so that people will not sweat when sitting on the sofa cushion for a long time due to the lack of air permeability. The steel plate is connected to the support plate to make the overall structure more stable.
[0008] Specifically, the limiting device includes a clamping member, both ends of which are fixedly connected with adjustment blocks, two groups of adjustment blocks pass through the outer shell and are arranged between the sliding grooves, one side of the clamping member is fixedly connected with a spring, and the number of the springs is three groups, and the other ends of the three groups of springs are fixedly connected to a baffle, and the bottom of the baffle is fixedly connected to the inner wall of the outer shell.
[0009] By adopting the above technical solution, the adjusting block is toggled, and the adjusting block moves in the sliding groove, driving the clamp to move. Since one side of the spring is connected to the stationary baffle, the spring is compressed, and the clamp leaves the gear, and the cushion can be rotated. After the adjustment is completed, just let go, the spring releases the elastic potential energy, and the clamp is inserted into the gear to limit the gear.
[0010] Specifically, the hair dryer is electrically connected to an external power source.
[0011] By adopting the above technical solution, the external power supply stably supplies power to the hair dryer, allowing the hair dryer to work normally and stably.

The two mounting plates are used to mount the screw rod, so that the screw rod can rotate between the two mounting plates. In order to make the screw rod rotate more smoothly, a bearing can be added, the bearing is embedded in the mounting plate, and the end of the screw rod is inserted into the bearing for rotation.
[0013] Beneficial effects of the utility model:
[0014] (1) In the sofa bed lifting structure described in the utility model, a hair dryer blows out cool air which passes through the air holes and the breathable sofa cushion and contacts people, so that people will not sweat when sitting on the sofa cushion for a long time due to the airtightness. The steel plate is connected to the support plate to make the overall structure more stable.
[0015] (2) The sofa bed lifting structure described in the utility model is that when the adjusting block is pushed, the adjusting block moves in the sliding groove, driving the clamping piece to move. Since one side of the spring is connected to the immovable baffle, the spring is compressed, and the clamping piece leaves the gear, and the cushion can be rotated. After the adjustment is completed, just let go, the spring releases the elastic potential energy, and the clamping piece is inserted into the gear to limit the gear and fix the cushion.
