The plurality of supporting plates 5 and the middle supporting single body 4 of the present embodiment just form a structure similar to the skeleton frame, but the skeleton frame formed by the supporting plates 5 and the middle supporting single body 4 of the present embodiment has a larger difference with the existing skeleton frame in structure, the supporting plates 5 of the skeleton frame of the present embodiment only have a half or less than a half of the length of the supporting plates of the existing skeleton frame, when the bed is wider, two or even three middle supporting single bodies 4 can be arranged between the first longitudinal supporting single body 2 and the second longitudinal supporting single body 3, thus, the length of the supporting plates 5 of the present embodiment may only have a third or even a quarter of the length of the supporting plates of the existing skeleton frame, we know that the supporting plates are especially the supporting plates of the essential structure, the longer the supporting plates are, the more easily cause the middle parts to be sunken and deformed due to the incapability of bearing force, and further affect the support of the mattress, and the design based on the present embodiment that the middle supporting single body is adopted, the length of the supporting plates 5 of the present embodiment can be designed to be shorter, compared with the existing long supporting plates, the supporting plates of the present embodiment is on the basis of realizing the stable support of the mattress, the present embodiment, the difficult deformation, the reliable support, the support plates 5 of the support plates has a longer service life of the support plates is longer.

It should be noted that the upper end surface of the middle supporting single body 4 and the upper end surfaces of the first longitudinal supporting single body 2 and the second longitudinal supporting single body 3 of the present embodiment are located at the same horizontal height, and the horizontal height of the upper end surface of the middle supporting single body 4 in the embodiment 1 is slightly lower than the horizontal height of the upper end surfaces of the first longitudinal supporting single body 2 and the second longitudinal supporting single body 3, because the supporting plate 5 in the embodiment 1 is disposed on the middle supporting single body 4, and the height difference between the upper end surface of the middle supporting single body 4 and the upper end surfaces of the first longitudinal supporting single body 2 and the second longitudinal supporting single body 3 is equal to the thickness of the supporting plate 5.

Example 3

As shown in fig. 10 to 14, in this embodiment, on the basis of embodiment 2, a plurality of first notches 43 and a plurality of second notches 44 are further respectively disposed on the left step 41 and the right step 42 of the middle support unit 4, a plurality of third notches 23 and a plurality of fourth notches 33 are respectively disposed on the third step 22 and the fourth step 32, shapes and sizes of the first notches 43, the second notches 44, the third notches 23 and the fourth notches 33 are matched with those of the support plate 5, both ends of the support plate 5 can be just placed in the first notches 43, the second notches 44, the third notches 23 and the fourth notches 33, and by disposing the first notches 43, the second notches 44, the third notches 23 and the fourth notches 33, a faster installation of the support plate 5 can be achieved, and a gap between the support plates 5 does not need to be calculated and set in a field installation, thereby effectively improving an installation efficiency, and by disposing the first notches 43, the second notches 44, the third notches 23 and the fourth notches 33, the support plate 5 can be prevented from sliding, displacement and the support plate 5 can provide stable and reliable support. Of course, in order to further enhance the stable reliability of the support plate 5, both ends of the support plate 5 may be fixed in the first, second, third and fourth recesses 43, 44, 23 and 33 by a common bolt, screw or the like.

It can be understood that, due to the introduction of the first notch 43, the second notch 44, the third notch 23 and the fourth notch 33, under the condition that the thickness of the support plate 5 is not changed, the level of the left step 41 and the level of the right step 42 of the middle support unit 4 of the present embodiment are slightly higher than that of the left step 41 and the right step 42 of the embodiment 2, so as to ensure that the whole support plate 5 is flush with the upper end surfaces of the first longitudinal support unit 2 and the second longitudinal support unit 3 after the support plate 5 is placed in the first notch 43, the second notch 44, the third notch 23 and the fourth notch 33, which is easy to understand for those skilled in the art and will not be described in detail herein.

In addition, in the practical operation process, the width of the supporting plate 5 is often slightly smaller than the widths of the first notch 43, the second notch 44, the third notch 23 and the fourth notch 33, so as to avoid the situation that the supporting plate 5 cannot be placed in the first notch 43, the second notch 44, the third notch 23 and the fourth notch 33, and in order to enhance the contact tightness between the supporting plate 5 and the first notch 43, the second notch 44, the third notch 23 and the fourth notch 33, as shown in fig. 15, the two ends of the supporting plate 5 of the embodiment are respectively sleeved with the soft sleeves 51, and the soft sleeves 51 can just fill the gaps between the supporting plate 5 and the first notch 43, the second notch 44, the third notch 23 and the fourth notch 33, so as to ensure the contact tightness, and the soft sleeves 51 can be made of common leather sleeves or other materials with certain elastic characteristics, and can be selected according to actual needs.

As shown in fig. 1, in order to obtain a certain supporting height, 4 supporting legs 6 may be added to the present embodiment, two ends of the first longitudinal supporting single body 2 and the second longitudinal supporting single body 3 are respectively provided with one supporting leg 6, one side of the two supporting legs 6 at two ends of the first longitudinal supporting single body 2 deviating from each other is subjected to corner cutting, and one side of the two supporting legs 6 at two ends of the second longitudinal supporting single body 3 deviating from each other is subjected to corner cutting. If the supporting legs 6 are not provided, the first longitudinal supporting single body 2, the second longitudinal supporting single body 3 and the transverse supporting single body 1 are supporting surfaces, and the requirements of surface support are often high and are slightly uneven, which may cause poor stability of the whole support; in addition, when the overall supporting height is not enough, the height requirement is met only by increasing the heights of the first longitudinal supporting single body 2, the second longitudinal supporting single body 3 and the transverse supporting single body 1, obviously, the cost is high, for this reason, point supporting is realized by increasing 4 supporting legs 6 in the embodiment, and the supporting legs 6 adopt corner cutting design, on the basis of ensuring that the supporting strength is enough, the supporting surface is reduced as far as possible, the supporting unevenness is avoided, and meanwhile, the cost is reduced as far as possible under the premise of meeting the supporting height.
