EMBODIMENT 1

[0044] Referring to FIGS. 1-9, this embodiment provides an elastic pad comprising a base 1 and spring modules 2; and the spring modules 2 are disposed in an array on the base 1.

[0045] The base 1 in this embodiment is an interconnectable base 1, which comprises plate units 11 and connecting members 12 for connecting the plate units 11; coupling members 13 adapted to the connecting members 12 are disposed on the plate units 11; multiple ones of the coupling members 13 are disposed at symmetrical positions on the plate units 11, and two of the coupling members 13 at the symmetrical positions are rotationally symmetrical; the coupling member 13 comprise arcuate slots, and the arcuate slots are divided into limiting ends 131 and release ends 132; a connecting member 12 comprises an operating member 121 and limiting posts 122 disposed in the arcuate slots; the operating member 121 is configured to drive the limiting posts 122 to move relative to the arcuate slots between a first position and a second position; two of the limiting posts 122 form a 180° angle; when the limiting posts 122 are in the first position, the two of the limiting posts 122 are respectively disposed at the release ends 132 of the arcuate slots on two of the plate units 11; and when the limiting posts 122 are in the second position, the two of the limiting posts 122 are respectively disposed at the limiting ends 131 of the arcuate slots on the two of the plate units 11 and are in limiting engagement with the limiting ends 131 in a direction opposite to an insertion direction of the limiting posts 122 into the arcuate slots.

[0046] As the coupling members 13 at symmetrical positions on the plate units 11 are rotationally symmetrical, when the two of the plate units 11 are connected, two of the coupling members 13 that are rotationally symmetrical can be arranged opposite to each other, the two of the limiting posts 122 of the connecting member 12 are then respectively inserted into the arcuate slots via the release ends 132, and the operating member 121 drives the limiting posts 122 to rotate from the first position to the second position, thereby connecting the two of the plate units 11. In the interconnectable base 1, the two of the plate units 11 can be connected by the connecting member 12, and the desired base 1 can be easily interconnected by selecting an appropriate number and type of the plate units 11. Moreover, the base 1 can be transported and packaged in a stacked form of the plate units 11, which significantly reduces packaging and transportation volume.

[0047] To achieve limiting engagement between the limiting posts 122 and the limiting ends 131, the limiting posts 122 comprise first portions and second portions, and the width of the first portions is smaller than a width of the limiting ends 131; and a width of the second portions is larger than the width of the limiting ends 131 but smaller than a width of the release ends 132. Thus, when the limiting posts 122 move to the second position, the width of the second portions is larger than the width of the limiting ends 131, enabling limiting engagement between the second portions and the limiting ends 131 in the insertion direction of the limiting posts 122 into the arcuate slots.

[0048] For user convenience, the operating member 121 comprises a mounting base 1211 and a handle 1212 disposed on an upper surface of the mounting base 1211, and the limiting posts 122 are disposed on a lower surface of the mounting base 1211. In addition, the mounting base 1211 is cylindrical, and the coupling members 13 correspondingly comprise chambers 133 adapted to the mounting base 1211, with the arcuate slots disposed at bottoms of the chambers 133.

[0049] In this embodiment, the plate units 11 are divided into horizontal plate units 111 and vertical plate units 112; the horizontal plate units 111 are disposed with the coupling members 13 on both sides along a length direction; and the vertical plate units 112 are disposed with coupling members 13 on both sides along a width direction and both sides along the length direction.

[0050] In this embodiment, a horizontal plate unit 111 can mount eight of the spring modules 2, and a vertical plate unit 112 can mount three or four of the spring modules 2, during assembly, eleven of the horizontal plate units 111 are arranged side by side, and the vertical plate units 112 are connected to both sides of the horizontal plate units 111, and the vertical plate units 112 include two of the vertical plate units capable of mounting three of the spring modules 2 and one of the vertical plate units capable of mounting four of the spring modules 2. The number of the plate units 11 can be increased or decreased as required, and is not limited to this embodiment.

[0051] In this embodiment, the horizontal plate units 111 and the vertical plate units 112 are respectively disposed with connecting posts 113 for securing the spring modules 2. In addition, a plurality of ribs are circumferentially disposed on a side surface of a connecting post 113; and the ribs are configured to have a limiting engagement with the spring module 2 about an axial direction of the connecting post. Thus, after the connecting posts are connected to the spring modules 2 by insertion, the limiting engagement is formed both in the insertion direction and about the connecting posts, securing the spring modules 2 to the base 1.

[0052] For easy insertion, upper end surfaces of the ribs have guide slopes. Embodiment 2

[0053] Referring to FIGS. 10 and 11, this embodiment differs from Embodiment 1 in that each of the spring modules 2 is corresponding connected to one of the connecting posts in Embodiment 1. The horizontal plate units 111 and the vertical plate units 112 are further divided into peripheral plate units 114 and inner plate units 115 according to installation positions; and the peripheral plate units 114 are disposed with the connecting posts for securing the spring modules 2. Thus, only the spring modules 2 on an outermost ring are connected by insertion, and other ones of the spring modules 2 can be secured to the base 1 by being directly or indirectly connected to the spring modules 2 via the connecting members 12. Embodiment 3

[0054] Referring to FIGS. 12 and 13, this embodiment uses the plate units 11 having uniform specification, a plate unit 11 is capable of mounting four of the spring modules 2, and the plate unit 11 is respectively disposed with the coupling members 13 on both sides along the width direction and both sides along the length direction. Embodiment 4

[0055] Referring to FIGS. 14 and 15, this embodiment adds a plate unit 11 on the basis of Embodiment 3, the plate unit can only mount one of the spring modules 2. This plate unit 11 is also provided with the coupling members 13 on both sides along the width direction and both sides along the length direction.
