[0044] Example 1

[0045] 1 to 9 , this embodiment provides an elastic pad, including a base 1 and a spring module 2 ; the spring module 2 is arranged in an array on the base 1 .

[0046] The base 1 in this embodiment is a splicable base 1, comprising: a unit plate 11 and a connecting member 12 for connecting the unit plate 11; a connecting member 13 that cooperates with the connecting member 12 is provided on the unit plate 11; a plurality of the connecting members 13 are provided at symmetrical positions on the unit plate 11, and the two connecting members 13 provided at the symmetrical positions are rotationally symmetrical; the connecting member 13 includes an arcuate groove, which is divided into a limit end 131 and a release end 132; the connecting member 12 includes an operating member 121 and a limit column placed in the arcuate groove 122; the operating member 121 is used to drive the limiting column 122 to move between the first position and the second position relative to the arc groove; there are two limiting columns 122, which form an angle of 180°; when the limiting column 122 is in the first position, the two limiting columns 122 are respectively located at the release ends 132 of the arc grooves in the two unit plates 11; when the limiting column 122 is in the second position, the two limiting columns 122 are respectively located at the limiting ends 131 of the arc grooves in the two unit plates 11, and are limitedly matched with the limiting ends 131 in the direction opposite to the direction in which the limiting column 122 is inserted into the arc groove.

[0047] Since the connecting fittings 13 at symmetrical positions on the unit board 11 are rotationally symmetrical, when connecting two unit boards 11, the two rotationally symmetrical connecting fittings 13 can be placed facing each other, and then the two limiting columns 122 of one connecting member 12 are respectively inserted into the arc groove through the release end 132, and then the limiting columns 122 are driven by the operating member 121 to rotate from the first position to the second position, thereby connecting the two unit boards 11 together. The above-mentioned splicable base 1 can connect two unit boards 11 together through a connecting member 12, and the required base 1 can be simply spliced ​​by selecting the appropriate number and type of unit boards 11. In addition, this base 1 is carried out in the form of stacking the unit boards 11 during packaging and transportation, which can greatly reduce the volume of packaging and transportation.

[0048] To achieve the limiting fit between the limiting post 122 and the limiting end 131, the limiting post 122 includes a first portion and a second portion. The width of the first portion is smaller than the width of the limiting end 131; the width of the second portion is larger than the width of the limiting end 131 and smaller than the width of the release end 132. In this way, when the limiting post 122 moves to the second position, the width of the second portion is larger than the width of the limiting end 131, so that the second portion and the limiting end 131 can be limitedly fitted along the direction in which the limiting post 122 is inserted into the arc groove.

[0049] To facilitate user operation, the operating member 121 includes a mounting seat 1211 and a handle 1212 disposed on the upper surface of the mounting seat 1211. The limiting post 122 is disposed on the lower surface of the mounting seat 1211. Furthermore, the mounting seat 1211 is cylindrical, and the connecting member 13 is correspondingly provided with a cavity 133 adapted to the mounting seat 1211, with an arc-shaped groove disposed at the bottom of the cavity 133.

[0050] In this embodiment, the unit plate 11 is divided into a horizontal unit plate 111 and a vertical unit plate 112; the horizontal unit plate 111 is provided with the connecting fittings 13 on both sides along the length direction; the vertical unit plate 112 is provided with the connecting fittings 13 on both sides along the width direction and on both sides along the length direction.

[0051] In this embodiment, the horizontal unit plates 111 can be installed with eight spring modules 2, and the vertical unit plates 112 can be installed with three or four spring modules 2. When assembled, eleven horizontal unit plates 111 are arranged side by side, and then the two sides of the horizontal unit plates 111 are connected to the vertical unit plates 11. The vertical unit plates 112 are divided into two vertical unit plates 112 that can be installed with three spring modules 2 and one vertical unit plate 112 that can be installed with four spring modules 2. The number of these unit plates 11 can be increased or decreased as needed and is not limited to this embodiment.

[0052] In this embodiment, the horizontal unit plates 111 and vertical unit plates 112 are each provided with a connecting column 113 for securing the spring module 2. Furthermore, the side surfaces of the connecting columns 113 are provided with multiple ribs along the circumference; these ribs are configured to engage with the axial position of the spring module 2 around the connecting columns. This ensures that when the connecting columns are plugged into the spring module 2, they form a positional engagement along both the insertion direction and the direction around the connecting columns, thereby securing the spring module 2 to the base 1.

[0053] In order to facilitate plugging, the upper end surface of the rib is a guiding inclined surface.

[0054] Example 2

[0055] Referring to Figures 10-11, this embodiment differs from Example 1 in that each spring module 2 in Example 1 is connected to a corresponding connecting column. The horizontal unit plates 111 and vertical unit plates 112 are further divided into peripheral unit plates 114 and inner unit plates 115 according to their installation locations; the peripheral unit plates 114 are provided with connecting columns for securing the spring modules 2. This ensures that only the outermost circle of spring modules 2 are connected to the plug-in connectors; the remaining spring modules 2 can be secured to the base 1 by directly or indirectly connecting to these spring modules 2 via connectors 12.

[0056] Example 3

[0057] 12-13 , in this embodiment, unit plates 11 of the same specification are used. This unit plate 11 can be installed with four spring modules 2 , and the unit plate 11 is provided with the connecting fittings 13 on both sides along the width direction and on both sides along the length direction.

[0058] Example 4

[0059] 14-15 , in this embodiment, a unit plate 11 is added on the basis of embodiment 3. This unit plate 11 can only install one spring module 2, and the unit plate 11 is provided with the connecting fittings 13 on both sides along the width direction and on both sides along the length direction.

[0060] The above is only a preferred specific embodiment of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with this technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the scope of protection of the present invention.
