Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings.
The embodiment of the utility model discloses a folding sofa bed.
Referring to fig. 1 to 3, the main structure includes a frame 1, a backrest 2, a folding portion 3 and a supporting seat 4, and a vertical projection of the frame 1 is in a [ -shaped structure to stably support the backrest 2, the folding portion 3 and the supporting seat 4. The back 2, the folding portion 3 and the supporting seat 4 in this embodiment are articulated in proper order, back 2 principle folding portion 3 one end is articulated with frame 1 for realize folding function, for the problem among the solution prior art, this embodiment is kept away from the folding portion 3 with back 2 one end and is articulated with frame 1, and set up telescopic machanism 5 on frame 1, through making telescopic machanism 5's flexible end be connected with supporting seat 4, the tilting machanism that is used for driving self upset that sets up on the rethread back 2, tilting machanism links with telescopic machanism 5, can drive supporting seat 4 initiative displacement, improve the stability of whole receipts and release.
Specifically, the turnover mechanism in this embodiment includes two gas springs 61 hinged to the backrest 2 for supporting assistance, and a support slide rod 62 slidably connected to the frame 1 for supporting the backrest 2 and cooperating with the telescopic mechanism 5. The output shaft of the gas spring 61 is hinged to the support slide bar 62. Slide ways 64 are arranged on the inner walls of the two sides of the frame 1, and pulleys 65 which are connected with the slide ways 64 in a sliding way are arranged at the two ends of the supporting slide bar 62, so that the supporting slide bar 62 can reduce the sliding resistance in the slide ways 64. The support slide bar 62 is further provided with a support wheel 9 for abutting against the backrest 2, which can be used for supporting the backrest 2 and reducing the abrasion of the support point of the backrest 2 when the backrest 2 is retracted.
In this embodiment, a support slide rail 63 is hinged on the frame 1, a support slide block 73 is slidably connected on the support slide rail 63, the support slide block 73 is fixedly connected with the support slide bar 62, a sliding driving structure for driving the support slide block 73 to move on the support slide rail 63 is arranged on the support slide rail 63, and the support slide block 73 is driven to move along the support slide rail 63 through the sliding driving structure and then is linked with the support slide bar 62.
