[0027] The embodiment of the present application provides a stretching mechanism for a drawer-type sofa bed, thereby solving the problem that the current sofa bed is locked by self-locking pulleys, but there is no limitation between the sofa and the bed body. When the sofa bed is pulled out to form a bed for use, the sofa bed is easily pushed by external force, causing the sofa bed to move or merge and reset.
[0028] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0029] The utility model embodiment discloses a stretching mechanism of a drawer-type sofa bed.
[0030] According to the attached Figure 1-5 As shown, a stretching mechanism of a drawer-type sofa bed comprises a sofa bed body 1 and a stretching bed 2 slidably connected inside the sofa bed body 1, and a fixing component 3 is provided on the side wall of the sofa bed body 1, and the fixing component 3 comprises:
[0031] A cardboard 4 is arranged inside the sofa bed body 1, and the cardboard 4 is plugged into the side wall of the stretching bed 2, and the cardboard 4 is used to limit the stretching bed 2;
[0032] The screw rod 401 is arranged inside the sofa bed body 1 , and is used to move the clamping plate 4 .
[0033] Slide grooves 202 are provided on both sides of the stretching bed 2 , and a slide rail 101 is fixedly connected to the inner side of the sofa bed body 1 , and the slide rail 101 is slidably connected to the inside of the slide groove 202 .
[0034] The bottom of the stretching bed 2 is rotatably connected with a pulley 203 , and the bottoms of the stretching bed 2 and the sofa bed body 1 are both fixedly connected with a limiting rod 102 .
[0035] The fixing component 3 also includes:
[0036] A rotating plate 301 is disposed on a side wall of the screw rod 401, and the rotating plate 301 is used to rotate the rotating plate 301;
[0037] The round rod 5 is arranged on the side wall of the sofa bed body 1 , and is used to fix the rotating plate 301 .
[0038] A fixing plate 402 is fixedly connected to the side wall of the sofa bed body 1, a screw rod 401 is rotatably connected to the inside of the fixing plate 402, and a clamping plate 4 is threadedly connected to the outer peripheral wall of the screw rod 401. By rotating the rotating plate 301 and the screw rod 401, the clamping plate 4 can be driven to slide inside the sofa bed body 1 until the clamping plate 4 is inserted into the inside of the card slot 201, so as to limit the stretching bed 2.
[0039] The clamping plate 4 is slidably connected to the inside of the sofa bed body 1 . The side wall of the stretching bed 2 is provided with a plurality of clamping slots 201 , and the stretching bed 2 is clamped inside the clamping slots 201 .
[0040] The round rod 5 passes through the side wall of the fixed plate 402, and the side wall of the rotating plate 301 is provided with multiple groups of circular grooves 302. The round rod 5 is inserted into the inside of the circular groove 302. By pulling the convex plate 502 inward, the round rod 5 can be driven to shrink inside the fixed plate 402, and the rotating plate 301 can be rotated at this time.
[0041] The end of the round rod 5 is fixedly connected with a convex plate 502, which passes through the side wall of the fixed plate 402. The convex plate 502 is slidably connected to the inside of the fixed plate 402. The outer wall of the round rod 5 is sleeved with a spring 501, and the two ends of the spring 501 are respectively fixedly connected to the side wall of the convex plate 502 and the inside of the fixed plate 402. The round rod 5 can be moved outward by the pulling force of the spring 501. At this time, the round rod 5 will be inserted into the inside of the circular groove 302.
[0042] When the utility model is in use, the convex plate 502 is first pulled inwards to drive the round rod 5 to shrink inside the fixed plate 402. At this time, the rotating plate 301 and the screw rod 401 can be rotated. The rotation of the screw rod 401 can drive the clamping plate 4 to slide and retract inside the sofa bed body 1. Then, the stretching bed 2 is pulled outwards. Finally, the screw rod 401 is rotated in the opposite direction to drive the clamping plate 4 to move until the clamping plate 4 is plugged into the inside of the clamping slot 201 to limit the stretching bed 2. At this time, the sofa bed body 1 and the stretching bed 2 can be used as beds.
