A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0024] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, 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 cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0025] Under the existing technology, when a bed of a different size needs to be replaced, since the size of the bed cannot be flexibly changed, the only option is to re-order and process a new bed. The factory needs to re-process and reschedule the production, the ordering cycle is slow, and the cost of purchasing furniture will increase.

[0026] In order to solve the above problems, Figures 1 to 6 As shown, the utility model provides an adjustable row frame, which includes a first module 1 and a second module 2. The first module 1 and the second module 2 are formed by bending a tube body with a rectangular cross-section. The first module 1 and the second module 2 are U-shaped. A first plug-in portion 21 is formed at the end of the second module 2. A first plug-in cavity 11 is formed at the end of the first module 1. The first plug-in portion 21 is plugged into the first plug-in cavity 11. The first module 1 and the second module 2 form a rectangle, which is perpendicular to the plug-in direction of the first plug-in portion 21. The first module 1 and the second module 2 are paved with a first rib plate 20, and a mattress can be placed on the first rib plate 20.

[0027] The second module 2 is U-shaped, so two groups of first plug-in parts 21 are formed. When the second module 2 is inserted into the first module 1, the area of ​​the overall frame frame surrounded by the first module 1 and the second module 2 will be reduced. When the area of ​​the frame frame needs to be expanded, the second module 2 needs to be pulled out from the first module 1. In this way, the size of the frame frame can be flexibly adjusted. When the size of the bed needs to be changed, it can be achieved by pulling out the second module 2, saving procurement costs. There is no need to plan the size in advance, which is more convenient. At the same time, the processing plant can uniformly produce the first module 1 and the second module 2, and the supply is faster.

[0028] The first straight teeth 12 are formed on the inner wall of one side of the first plug-in cavity 11, and the first motor 5 is installed on one side of the front end of the first plug-in portion 21. The first gear 8 is installed on the front end of the first motor 5. The first motor 5 drives the first gear 8 to rotate, and the first gear 8 meshes with the first straight teeth 12. The first straight teeth 12 are distributed along the length direction of the first plug-in cavity 11. When the first motor 5 drives the first gear 8 to rotate, the first gear 8 meshes with the first straight teeth 12, and the second module 2 can be driven to move along the length direction of the first plug-in cavity 11, so as to realize the automatic adjustment of the length of the row frame, which is more labor-saving.

[0029] A first slide groove 13 is formed on the outside of the first plug-in cavity 11, and the length direction of the first slide groove 13 is the length direction of the first plug-in cavity 11, so that the rocker can drive the first gear 8 to move. A first plug-in hole 81 is formed on the side of the first gear 8, and the first plug-in hole 81 is semicircular. The end of the rocker passes through the first slide groove 13 and is plugged into the first plug-in hole 81, and the rocker drives the first gear 8 to rotate. If the first motor 5 is not equipped or the first motor 5 is damaged, the rocker can be used to cooperate with the first gear 8, and the first gear 8 can be driven to rotate by rotating the rocker, so that the reliability of the utility model is higher and it can be adjusted at any time. The semicircular shape of the first plug-in hole 81 can limit the rocker, so that the rocker can stably drive the first gear 8 to rotate, and other asymmetric shapes of the first plug-in hole 81 can also be used.

[0030] The adjustable row frame also includes a third module 3 and a fourth module 4, which are formed by bending a tube body with a rectangular cross-section, and are L-shaped. The third module 3 and the fourth module 4 are plugged into each other to form a U-shape, and the end of the third module 3 away from the fourth module 4 is plugged into the first module 1 along the length direction of the first rib 20, and the end of the fourth module 4 away from the third module 3 is plugged into the second module 2 along the length direction of the first rib 20. The third module 3 and the fourth module 4 are installed with second ribs 30, and the second ribs 30 are overlapped on the first module 1 or the second module 2. The first ribs 20 and the second ribs 30 are arranged alternately, and the mattress will be placed on the first ribs 20 and the second ribs 30, so that the mattress support is more stable, and the first module 1, the second module 2, the third module 3 and the fourth module 4 form a rectangle.

[0031] By adding the third module 3 and the fourth module 4, the rib frame can be adjusted along the length direction of the first rib 20, that is, the width direction of the rib frame. In this way, the rib frame can be flexibly adjusted in both the length and width directions, so that the rib frame of the utility model can be changed into different sizes to adapt to rooms of different sizes and the size requirements of different customers. When the size of the bed is changed, there is no need to re-customize the rib frame. At the same time, during transportation, the first module 1, the second module 2, the third module 3 and the fourth module 4 can be disassembled for easy packaging and transportation, and then assembled in the bedroom.

[0032] The inner wall of the third module 3 is formed with second spur teeth 31 , and the end of the fourth module 4 is formed with a second motor 6 installed thereon. The second motor 6 drives the second gear 9 to rotate, and the second gear 9 meshes with the second spur teeth 31 .

[0033] The second motor 6 rotates synchronously with the first motor 5 so that when the length of the rack frame is lengthened, the second module 2 and the fourth module 4 can move synchronously to avoid jamming and make the length adjustment of the rack frame more accurate.

[0034] The third module 3 is provided with a second slide groove 32, and the side of the second gear 9 is provided with a second plug hole 91, which is semicircular and arranged in the second slide groove 32. Similarly, when the second motor 6 is damaged, the second gear 9 can be driven to rotate manually by using the rocker. The first plug hole 81, the second plug hole 91 and the third plug hole 101 have the same shape, so that the rocker can be universally plugged in. At the same time, the first slide groove 13, the second slide groove 32 and the third slide groove 60 all serve to facilitate the movement of the rocker therein.

[0035] The inner wall of the first module 1 and the inner wall of the second module 2 are formed with third spur teeth 50, and the ends of the third module 3 and the fourth module 4 are installed with third motors 7, which drive the third gear 10 to rotate, and the third gear 10 is meshed with the third spur teeth 50. The two sets of third motors 7 rotate synchronously, so that the width of the rack frame can be automatically adjusted to avoid jamming, and it is more stable and labor-saving.

[0036] A third slide groove 60 is provided on the first module 1 and the second module 2, and a third plugging hole 101 is provided on the side of the third gear 10. The third plugging hole 101 is semicircular and is arranged in the third slide groove 60. When adjusted, the two sets of rockers are used to rotate synchronously to avoid jamming.

[0037] The backs of the first module 1, the second module 2 and the third module 3 are provided with mounting holes 70. The first motor 5, the second motor 6 and the third motor 7 of the utility model are all installed by bolts. The three groups of motors can be disassembled or installed through the mounting holes 70, which is convenient for maintenance.
