[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] Example 1, see Figure 1-3As shown, a tension-adjustable mattress with a twill, comprising a rectangular bed frame 1, a twill 2, a fixing frame 3 and a retractable adjusting device 4, wherein the adjacent ends of four frames 11 of the rectangular bed frame 1 are movably connected, specifically, the adjacent ends of the four frames 11 are fixed by universal corner connections, that is, the four frames 11 can rotate freely, and the bottom of the frames 11 is an arc surface. The four sides of the twill 2 are installed on the top of the four frames 11.

[0025] The fixing frame 3 is arranged inside the frame 11. The fixing frame 3 is a triangular profile. An inserting portion 31 is provided at one corner of the profile facing the frame 11. A groove 15 is provided in the middle of the inner side of the frame 11. A metal protective layer 12 is provided inside the frame 11. The metal protective layer 12 extends into the groove 15. The inserting portion 31 is inserted into the groove 15. The groove 15 contacts the inserting portion 31 through the metal protective layer 12. Each frame 11 rotates around the corresponding inserting portion 31 through the groove 15.

[0026] The adjusting device 4 includes a threaded buckle 41 and an extension rope 42. One end of the threaded buckle 41 is connected and fixed to the inner bottom of the frame 11, and the other end of the threaded buckle 41 is connected and fixed to the inner bottom of the opposite frame 11 through the extension rope 42. The fixing frame 3 is provided with a clearance notch 32 corresponding to the adjusting device 4. The two ends of the adjusting device 4 are connected and fixed to the bottom of the frame 11 after passing through the corresponding clearance notch 32. The threaded buckle 41 is a prior art. The tension of the adjusting device 4 and the tension of the stretching net 2 are balanced with the fixing frame 3 as the fulcrum.

[0027] In this embodiment, the movable part of the threaded buckle 41 is rotated to tighten the adjusting device 4, that is, the bottoms of the opposite frames 11 move toward each other, and since the frames 11 rotate around the insertion part 31 through the groove 15, the tops of the frames 11 move away from each other, thereby tightening the stretching net 2. On the contrary, the tension of the stretching net 2 is loosened. The stretching bed is supported by the bottom surface of the frame 11 and the bottom surface of the fixing frame 3.

[0028] Example 2, see Figure 1 , Figure 4 and Figure 5 As shown, the difference between the embodiment 1 and the embodiment 1 is that the rotating structure of the rectangular bed frame 1 and the fixing frame 3 is different. Specifically, a rotating hole 13 is provided in the middle of the frame 11 along the length direction, and the fixing frame 3 is a rectangular frame, and its cross section is a circular or annular profile. The fixing frame 3 is inserted into the rotating hole 13, and the frame 11 rotates around the fixing frame 3. In this embodiment, the fixing frame 3 is built-in to realize a hidden design. The bed is supported by the bottom surface of the frame 11.

[0029] Example 3, see Figure 6As shown, the difference between the embodiment 2 and the embodiment 2 is that the adjusting device 4 is different. Specifically, the adjusting device 4 includes a fixing bracket 14 and a screw rod 43 arranged on the inner bottom of the frame 11, the fixing bracket 14 is provided with a nut seat 44, and the two ends of the screw rod 43 are respectively threadedly connected with the nut seat 44 of the fixing bracket 14 on the frame 11.

[0030] The screw rod 43 is rotated, and the two opposite nut seats 44, the fixing bracket 14 and the bottom of the frame 11 move toward each other. As the frame 11 rotates around the fixing bracket 3, the top of the frame 11 moves away from each other, thereby tightening the stretching net 2. Otherwise, the tension of the stretching net 2 is loosened.

[0031] In the present invention, the adjusting device 4 can also be a structure such as a cylinder or a motor, which can drive the bottom of the frame 11 to move, so that the top of the frame 11 moves, thereby tightening the tension net 2. It should be noted that the adjusting range of the adjusting device 4 in the present invention is smaller than that of the rectangular bed frame 1, and the adjusting range of the adjusting device 4 is fine adjustment.
