[0002] A folding bed is a simple bed designed using the principle of joints. For the sake of convenience and space saving, it can be folded and stored in various ways. It is convenient, practical and easy to store. Folding beds are often used in disaster relief sites during natural disasters.

[0003] The existing folding bed is found that the height of the four legs (bed legs) cannot be adjusted when in use, and the ground at the disaster relief site of a natural disaster may be uneven, so the entire folding bed may be uneven and shake when in use. In order to prevent the shaking, bricks and stones need to be used as pads, so improvements are needed;

[0004] For this reason, it is necessary to invent a modular folding bed. Summary of the Invention

[0005] Therefore, the present invention provides a combined folding bed to solve the problems in the background technology.

[0008] There are four spiral strips, each of which is fixedly sleeved on the outside of the top of each of the four legs. Each of the four grooves has a spiral groove matching the spiral strips, and the four spiral strips are embedded in the four spiral grooves.

[0009] There are four threaded rods, each of which is located inside one of the four legs. The bottom ends of the four threaded rods extend to the outside of the bottom of the four legs. The four threaded rods are each sleeved with a threaded block. The threaded block is connected to the threaded rod through a thread. The four threaded blocks are respectively embedded in the bottom of the four legs.

[0010] The pads are provided in four numbers, and the four pads are fixedly connected to the bottom ends of the four threaded rods respectively.

[0011] Preferably, a plurality of shift rods evenly distributed in a circumference are fixedly sleeved on the outside of the four threaded blocks.

[0031] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0032] Refer to the attached Figure 1 -Attached Figure 7 The utility model provides a combined folding bed, comprising:

[0033] The bed board 1 is provided with two, and the two bed boards 1 are connected by a movable hinge seat, and two grooves 2 are provided at the bottom of the two bed boards 1, and the bottom of the four grooves 2 is provided with a support leg 3, and the top of the four support legs 3 extends into the interior of the groove 2, and the four support legs 3 are provided as hollow cores;

[0034] There are four spiral strips 4, which are fixedly sleeved on the top of the four legs 3. The four grooves 2 are each provided with a spiral groove 5 matching the spiral strips 4. The four spiral strips 4 are respectively embedded in the four spiral grooves 5.

[0035] There are four threaded rods 6, each of which is located inside the four legs 3. The bottom ends of the four threaded rods 6 extend to the outside of the bottom of the four legs 3. The outsides of the four threaded rods 6 are all sleeved with threaded blocks 7, which are connected to the threaded rods 6 by threads. The four threaded blocks 7 are respectively embedded in the bottom of the four legs 3;

[0036] There are four spacers 8, each of which is fixedly connected to the bottom ends of the four threaded rods 6;

[0037] The four threaded blocks 7 are all fixedly sleeved with a plurality of shifting rods 9 evenly distributed in a circumference;

[0038] In this embodiment, the threaded block 7 is rotated. Since the threaded block 7 is embedded in the bottom of the leg 3 and cannot move, the threaded block 7 can move the threaded rod 6 and the pad 8 downward when it is rotated, so that the length of the leg 3 can be lengthened, thereby achieving the effect of adjusting the height of the leg 3;

[0039] In order to achieve the purpose of guidance, the present device adopts the following technical solution: the four threaded rods 6 are each provided with a prism groove 10, the four prism grooves 10 are each provided with a prism 11, the tops of the four prisms 11 are fixedly connected to a connecting block 12, the four connecting blocks 12 are respectively fixedly connected to the inside of the four legs 3, and the prism 11 is slidably connected to the prism groove 10. The prism 11 and the prism groove 10 can guide the threaded rod 6, thereby ensuring its stable movement;

[0040] In order to prevent the inner sides of the two bed boards 1 from directly contacting each other, the device adopts the following technical solution: a sponge pad 13 is provided on the top of each of the two bed boards 1, and a rubber strip 14 is fixedly connected to the inner sides of the two bed boards 1. The inner sides of the two rubber strips 14 are in contact with each other, and the rubber strips 14 can prevent the inner sides of the two bed boards 1 from directly contacting each other;

[0041] Among them, in order to achieve the purpose of carrying the bed body to move, this device adopts the following technical solution: two pull rods 15 are fixedly connected to the front and rear sides of the two bed boards 1, and two buckles 16 are provided on the outside of the four pull rods 15. The design of the pull rods 15 allows the folding bed to be carried and moved when it is in the folded state;

[0042] In order to achieve the purpose of reducing wear, the present device adopts the following technical solution: the threaded block 7 is connected to the support leg 3 through a bearing, and the bearing connection can reduce wear.

[0043] When the height of the legs 3 needs to be adjusted, the lever 9 is pushed by hand, so that the threaded block 7 can be rotated. Since the threaded block 7 is embedded in the bottom of the legs 3 and cannot move, the threaded block 7 can make the threaded rod 6 and the pad 8 move downward, so that the length of the legs 3 can be lengthened, thereby achieving the effect of adjusting the height of the legs 3. The same principle can be used to adjust the height of the other four legs 3. In this way, at the disaster relief site, the height of the four legs 3 can be appropriately adjusted according to the ground environment at the site, thereby avoiding the uneven shaking of the folding bed. In this way, there is no need to use bricks and stones to pad. In actual use, adjacent folding beds can be combined and used together through the design of the buckle 16.

[0044] When the folding bed is not in use, the legs 3 can be twisted and then unscrewed from the bed board 1 by the action of the spiral strips 4 and the spiral grooves 5. The other three legs can be unscrewed by the same principle, and then the two bed boards 1 can be folded toward the middle. In this way, the two bed boards 1 can be folded together, thereby reducing the volume of the folding bed and making it easier to store.

[0045] The above are merely preferred embodiments of the present invention. Anyone skilled in the art may utilize the above-described technical solutions to modify the present invention or create equivalent technical solutions. Therefore, any simple modification or equivalent replacement based on the technical solutions of the present invention falls within the scope of protection claimed by the present invention.
