DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0022] 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.

[0023] like Figure 1-4 The sofa bed frame with a slide rail device shown in the figure comprises a bottom plate 1, on the bottom end surface of which four main supporting legs 2 are fixedly connected, and the four main supporting legs 2 are distributed in a rectangular shape.

[0024] Furthermore, in order to improve the overall practicality of the sofa bed, slide rails 3 are horizontally fixedly arranged on the two opposite side walls of the bottom plate 1, both ends of the two slide rails 3 are closed, sliders 4 are slidably arranged in the two slide rails 3, and connecting plates 5 are fixedly connected to the outer end surfaces of the two sliders 4. An adjustment plate 6 is fixedly connected between the two connecting plates 5, and auxiliary support legs 7 are arranged on the adjusting plates 6.

[0025] Furthermore, in order to improve the stability of the adjustment plate 6 after adjustment and to improve people's comfort, a locking component for locking the adjustment plate 6 is provided between the adjustment plate 6 and the base plate 1 .

[0026] The locking assembly includes a fixed long block 8 and a locking rod 9. The fixed long block 8 is horizontally fixed on the side wall of the base plate 1. A plurality of locking holes 10 are provided on the fixed long block 8. A locking block 11 is fixedly provided on the side wall of one end of the locking rod 9. The locking block 11 is located in the locking hole 10. The other end of the locking rod 9 is connected to the side wall of the adjustment plate 6. A rotating groove 12 is provided on the side wall of the adjustment plate 6. A rotating block 13 is fixedly provided on one end of the locking rod 9 close to the adjustment plate 6. The rotating block 13 is rotatably provided in the rotating groove 12.

[0027] It should be noted that: when the sofa bed needs to be adjusted in shape, the slider 4 is moved to one end of the slide rail 3, and then the adjustment plate 6 is horizontally connected to one end of the base plate 1, and the adjustment plate 6 is supported by the auxiliary support legs 7, so that the sofa bed is adjusted to the shape of a bed for people to lie down and rest; the slider 4 is moved to the middle section of the slide rail 3, and the adjustment plate 6 is placed vertically, and then the locking rod 9 is pulled outward and applied with a rotation effect, so that the locking block 11 at the other end of the locking rod 9 is aligned with the locking hole 10 provided in the fixed long strip 8, and then the locking rod 9 is pushed inward to insert the locking block 11 into the locking hole 10, so as to lock the vertical state of the adjustment plate 6, thereby adjusting the sofa bed to the shape of a sofa.

[0028] The above arrangement is performed by arranging the slide rail 3 on the side wall opposite to the bottom plate 1, arranging the slider 4 in the slide rail 3, and connecting the slider 4 with the adjustment plate 6 through the connecting plate 5, and moving the slider 4 to one end of the slide rail 3, and placing the adjustment plate 6 horizontally, so that the sofa bed is adjusted to the shape of a bed; further, by moving the slider 4 to the middle section of the slide rail 3, and placing the adjustment plate 6 vertically, and then by inserting the locking block 11 into the locking hole 10, the vertical state of the adjustment plate 6 is locked, so that the sofa bed is adjusted to the shape of a sofa. When the sofa bed is in the sofa shape, seats are provided at both ends of the bottom plate 1, which can provide rest for multiple people at the same time, thereby improving the practicality of the sofa bed.

[0029] Among them, Figure 1 , 2 As shown in Figures 6 and 7, storage grooves 17 are respectively provided on the end surfaces of both sides of the adjustment plate 6, and the auxiliary supporting legs 7 are stored in the storage grooves 17. One end of the auxiliary supporting leg 7 is rotatably connected to the side wall of one end of the storage grooves 17. When the sofa bed is in the sofa state, the auxiliary supporting leg 7 can be stored through the storage grooves 17, thereby reducing the collision between people and the auxiliary supporting legs 7, ensuring safety while improving the practicality of the sofa bed.

[0030] like Figure 4 , 5 As shown, a limiting groove 14 is provided at the inner end of the rotating groove 12 , and a limiting block 15 is arranged in the limiting groove 14 . The limiting block 15 is fixedly connected to an end of the rotating block 13 away from the locking rod 9 .

[0031] The arrangement of the limiting block 15 and the limiting groove 14 can prevent the locking rod 9 from falling off the adjusting plate 6, thereby facilitating the adjustment of the adjusting plate 6 and further improving the practicality of the sofa bed.

[0032] like Figure 1 As shown, a fixing groove 16 is further provided on the side wall of the adjustment plate 6, and the fixing groove 16 is matched with the locking block 11, and the fixing groove 16 is located above the rotating groove 12. After the sofa bed is adjusted to the shape of a bed, the locking rod 9 is rotated to align the locking block 11 with the fixing groove 16, and the locking block 11 is inserted into the fixing groove 16 to fix the locking rod 9. By fixing the locking rod 9, the shaking of the locking rod 9 during use is avoided, thereby making the sofa bed more practical.

[0033] The locking block 11 is made of a magnetic metal material, and magnets are fixedly arranged in the locking hole 10 and the fixing groove 16. The magnets and the magnetic metal are magnetically attracted to each other. The locking block 11 can be adsorbed by the magnet, thereby preventing the locking block 11 from falling out of the locking hole 10 or the fixing groove 16, further improving the overall safety of the sofa bed.

[0034] Working principle: when the sofa bed needs to be adjusted in shape, the slider 4 is moved to one end of the slide rail 3, and then the adjustment plate 6 is horizontally connected to one end of the bottom plate 1, and the adjustment plate 6 is supported by the auxiliary support legs 7, so that the sofa bed is adjusted to the shape of a bed for people to lie down and rest; the slider 4 is moved to the middle section of the slide rail 3, and the adjustment plate 6 is placed vertically, and then the locking rod 9 is pulled outward and applied with a rotation effect, so that the locking block 11 at the other end of the locking rod 9 is aligned with the locking hole 10 provided in the fixed long strip 8, and then the locking rod 9 is pushed inward to insert the locking block 11 into the locking hole 10, so as to lock the vertical state of the adjustment plate 6, thereby adjusting the sofa bed to the shape of a sofa.

[0035] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
