Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a deformable storage rack for a living room sofa bed. Background Technology

[0002] A convertible living room sofa bed storage shelf is a multifunctional piece of furniture that combines sofa, bed, and storage functions. It is often used in small living rooms, rental apartments, or multifunctional rooms. It can be used as a sofa for relaxation during the day and can be transformed into a bed at night to meet sleep needs. At the same time, it can store clothes, bedding, and other items through built-in storage space, which greatly saves indoor space.

[0003] The existing technology has the following problems: In existing technology, sofa bed storage shelves are usually placed in the living room or other leisure areas to provide a comfortable resting space and also have a certain storage function. However, the height of the support legs at the bottom of the sofa bed is fixed. Due to the low height of the support legs, a lot of dust and debris easily accumulates at the bottom of the sofa bed. Over time, the dust accumulation at the bottom will increase and become more and more difficult to clean. In particular, some cleaning tools, such as vacuum cleaner heads or brooms, usually have difficulty entering the narrow space at the bottom of the sofa bed, making these places blind spots for cleaning. Utility Model Content

[0004] The main purpose of this utility model is to provide a deformable storage rack for living room sofa beds, which can effectively solve the problem that due to the low height of the support legs, a large amount of dust and debris easily accumulates at the bottom of the sofa bed, and over time, the dust accumulation at the bottom will increase and become more and more difficult to clean.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A deformable living room sofa bed storage rack includes a base with two storage boxes slidably connected inside the base. A flip-up plate is hinged to the top of the base, and armrests are fixedly connected to the left and right sides of the top of the flip-up plate. Two fixed plates are fixedly connected to the rear of the base, and a pivot is rotatably connected between the two fixed plates. A backrest is fixedly connected to the outer periphery of the pivot. An auxiliary mechanism is provided on the outer side of the base, and an adjustment mechanism is provided on the right side of the pivot. The auxiliary mechanism includes a mounting cylinder, the inner side of which is fixedly connected to the outer side of the base, and a lead screw is rotatably connected inside the mounting cylinder, with a lifting column threadedly connected to the outer circumference of the lead screw. The adjustment mechanism includes a mounting box, which is fixedly connected to the right side of the base on the left side. A worm gear is rotatably connected inside the mounting box. A worm wheel is meshed with the top of the worm gear. A rotating rod is fixedly connected inside the worm wheel. A driving bevel gear is fixedly connected to one end of the rotating rod. A driven bevel gear is meshed with the rear side of the driving bevel gear.

[0006] Preferably, the auxiliary mechanism is provided in four sets, which are symmetrically distributed on the left and right sides of the base.

[0007] Preferably, the outer surface of the mounting cylinder is provided with a sliding groove, and a limit block is fixedly connected to the outer periphery of the lifting column.

[0008] Preferably, the outer side of the lifting column is slidably connected to the inside of the mounting cylinder.

[0009] Preferably, the outer side of the limiting block is slidably connected to the inside of the groove.

[0010] Preferably, four slides and four limiting blocks are provided. The slides are arranged in a ring around the outer periphery of the mounting cylinder, and the limiting blocks are arranged in a ring around the outer periphery of the lifting column.

[0011] Preferably, the other end of the rotating rod is rotatably connected to the inner wall of the mounting box, and one end of the rotating shaft passes through the mounting box and is fixedly connected to the driven bevel gear.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model provides a deformable storage rack for a living room sofa bed. Rotating the screw can drive the lifting column to move axially along the mounting cylinder, raising the height of the sofa bed. This makes it easier for cleaning tools to reach under the sofa bed for cleaning and also facilitates air circulation under the sofa bed, thus preventing the sofa bed from getting moldy and damaged due to damp ground. At the same time, the height of the lifting column can be adjusted according to the flatness of the ground to ensure that the furniture is placed stably. It is suitable for different ground conditions and improves the practicality of the device.

[0013] 2. This utility model provides a deformable storage rack for a living room sofa bed. The backrest angle can be conveniently adjusted through an adjustment mechanism. Rotating the adjustment handwheel drives the worm gear to rotate. The worm gear meshes with the worm wheel to make the rotating rod rotate. The active bevel gear rotates synchronously with the rotating rod and drives the driven bevel gear to rotate, thereby driving the rotating shaft and the backrest to rotate. No multiple people are required to cooperate; one person can complete the adjustment. The operation is simple and efficient. At the same time, the worm gear and worm wheel structure has a self-locking function, so the backrest angle can be stably fixed after adjustment to prevent it from shifting on its own.

Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figure 1-5 As shown, a deformable living room sofa bed storage rack includes a base 1, with two storage boxes 2 slidably connected inside the base 1, a flip plate 3 hinged to the top of the base 1, armrests 4 fixedly connected to the left and right sides of the top of the flip plate 3, two fixed plates 5 fixedly connected to the rear side of the base 1, a pivot 6 rotatably connected between the two fixed plates 5, a backrest 7 fixedly connected to the outer periphery of the pivot 6, an auxiliary mechanism 8 provided on the outer side of the base 1, and an adjustment mechanism 9 provided on the right side of the pivot 6. The auxiliary mechanism 8 includes a mounting cylinder 81, which is fixedly connected to the outer side of the base 1. A lead screw 82 is rotatably connected inside the mounting cylinder 81, and a lifting column 83 is threadedly connected to the outer circumference of the lead screw 82.

[0018] It should be noted that when the screw 82 is rotated clockwise, due to the threaded engagement between the screw 82 and the lifting column 83, the lifting column 83 will extend downward along the axial direction of the mounting cylinder 81. After the bottom contacts the ground, the screw 82 will continue to be rotated, which will lift the base 1 as a whole. This allows cleaning tools such as brooms and vacuum cleaners to easily reach the bottom of the base 1 to thoroughly clean the accumulated dust and debris. It also increases the air circulation space at the bottom, reducing the probability of mold growth in a damp environment and preventing the wooden or metal parts at the bottom of the base 1 from rusting or becoming damaged by moisture. When the screw 82 is rotated counterclockwise, the lifting column 83 will retract upward along the axial direction of the mounting cylinder 81, and the base 1 will fall back to its initial position, ensuring stability during daily use.

[0019] The adjustment mechanism 9 includes a mounting box 91. The left side of the mounting box 91 is fixedly connected to the right side of the base 1. A worm gear 92 is rotatably connected inside the mounting box 91. A worm wheel 93 is meshed with the top of the worm gear 92. A rotating rod 94 is fixedly connected inside the worm wheel 93. A driving bevel gear 95 is fixedly connected to one end of the rotating rod 94. A driven bevel gear 96 is meshed with the rear side of the driving bevel gear 95.

[0020] It should be noted that the adjustment mechanism 9 utilizes the self-locking characteristic of the worm gear 92 transmission, meaning that only the active rotation of the worm gear 92 can drive the worm wheel 93 to rotate, and the worm wheel 93 cannot drive the worm gear 92 in the reverse direction. This ensures that after the backrest 7 is adjusted to the target angle, it can maintain a stable angle without deviation even under the pressure of a person leaning against it, avoiding any impact on the user experience due to changes in angle. The worm wheel 93 drives the rotating rod 94 to rotate synchronously. The active bevel gear 95 at one end of the rotating rod 94 meshes with the driven bevel gear 96, converting the horizontal rotational motion into a vertical rotational motion. The driven bevel gear 96 is fixedly connected to the rotating shaft 6, ultimately driving the rotating shaft 6 and the outer periphery of the backrest 7 to rotate, thereby achieving the adjustment of the tilt angle of the backrest 7.

[0021] like Figure 1 As shown, the auxiliary mechanism 8 is specifically provided in four groups, which are symmetrically distributed on the left and right sides of the base 1.

[0022] It should be noted that the four sets of mechanisms correspond to the four corners of the base 1, which can evenly distribute the weight of the sofa bed (including the base 1, storage box 2, flip board 3 and the user's weight) to the four support points, avoiding excessive force on a single point that could cause deformation or damage to the components.

[0023] like Figure 4 As shown, a sliding groove 84 is provided on the outer surface of the mounting cylinder 81, and a limit block 85 is fixedly connected to the outer periphery of the lifting column 83.

[0024] It should be noted that the rotational freedom of the lifting column 83 is restricted to ensure the stability of height adjustment.

[0025] like Figure 4 As shown, the outer side of the lifting column 83 is slidably connected to the inside of the mounting cylinder 81.

[0026] It should be noted that this enables the lifting column 83 to move stably.

[0027] like Figure 3 As shown, the outer side of the limiting block 85 is slidably connected to the inside of the slide groove 84.

[0028] It should be noted that the slide 84 serves to limit the position of the limit block 85.

[0029] like Figure 4 As shown, there are four sliding grooves 84 and four limiting blocks 85. The sliding grooves 84 are arranged in a ring around the outer periphery of the mounting cylinder 81, and the limiting blocks 85 are arranged in a ring around the outer periphery of the lifting column 83.

[0030] It should be noted that the slide groove 84 and the limiting block 85 are evenly distributed along the circumference of the mounting cylinder 81 and the lifting column 83, which can evenly distribute the reaction force of the lifting column 83 when it rotates to the four limiting points, thus avoiding damage to a single set of limiting blocks due to concentrated force.

[0031] like Figure 5 As shown, the other end of the rotating rod 94 is rotatably connected to the inner wall of the mounting box 91, and one end of the rotating shaft 6 passes through the mounting box 91 and is fixedly connected to the driven bevel gear 96.

[0032] It should be noted that, in order to enable the rotating rod 94 to rotate stably, the connection between the rotating shaft 6 and the driven bevel gear 96 can realize the transmission power directly to the backrest 7.

[0033] Working principle: When cleaning the bottom of the sofa bed or adapting to uneven ground, rotate the lead screw 82 of the auxiliary mechanism 8 clockwise. The lead screw 82 is threaded into the lifting column 83. Under the limiting action of the slide groove 84 and the limit block 85, the lifting column 83 moves downward along the mounting cylinder 81. The lifting column 83 contacts the ground and lifts the base 1. Adjust to the appropriate height as needed. If the ground is uneven, the height of the corresponding lifting column 83 of the auxiliary mechanism 8 can be adjusted individually to ensure overall stability. After cleaning, rotate the lead screw 82 counterclockwise to reset the lifting column 83. When changing from sofa to bed mode, hold the armrest 4 and lower it. Flip the flip plate 3 so that the armrest 4 is placed on the ground and the flip plate 3 and the base 1 are on the same plane, transforming it into a bed shape, so that it is flush with the backrest 7 to form a complete bed surface. When the bed state is transformed into the sofa state, flip the flip plate 3 in the opposite direction. When adjusting the tilt angle of the backrest 7, first rotate the worm gear 92. The worm gear 92 meshes with the worm wheel 93 to make the rotating rod 94 rotate. The driving bevel gear 95 drives the driven bevel gear 96 and the rotating shaft 6 to rotate, adjusting the backrest 7 to a suitable tilt angle. Hold the handle of the storage box 2 and pull it out to pull out the storage box 2. After putting in or taking out items, push the storage box 2 back into the base 1.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
