Elastic module and elastic pad

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority based on the Chinese patent application filed with the State Intellectual Property Office of China on March 29, 2024, with application number: 2024103718116, and the name of the invention: "An elastic module and elastic pad". The content of the Chinese patent application is hereby introduced into the text of this application. Technical Field

[0003] The present invention relates to household articles, in particular to elastic household articles. Background Art

[0004] Furniture, such as sofa beds, is an essential part of people's lives. Most existing beds and sofa beds are equipped with elastic cushions. These cushions have a certain degree of elasticity, providing support when people lie down, and offer a certain degree of comfort compared to hard cushions.

[0005] Existing elastic cushions are typically integrated, non-detachable, and enclosed, integral cushions consisting of a base layer, a spring layer, a sponge overlay layer, and closed side panels. Specifically, the spring layer is placed on the base layer, the sponge overlay layer is placed on top of the spring layer, and the closed side panels are connected between the sponge overlay layer and the base layer to form a closed space. However, in actual use, such elastic cushions suffer from poor stability, low comfort, inconvenience in transportation, and take up a large amount of space when stored.

[0006] For this purpose, a technical solution has emerged in the prior art that divides the spring layer into multiple independent elastic units. These elastic units can be connected together for use, or they can be disassembled and transported. However, even so, there is still the problem of being inconvenient to transport after disassembly and being too large. In this case, it is often necessary to compress the elastic units to reduce their volume before storage or transportation. However, the elastic units are prone to losing their elasticity after being compressed for a long time, and because they are always in a compressed state, they may suddenly release their elastic restoring force, causing some unpredictable accidents. This elastic pad connected by independent springs can replace springs of different hardness at different positions according to personal needs. Each spring is connected to each other in the middle and bottom, making it not very convenient to disassemble and assemble. Summary of the Invention

For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0100] Example 1

[0101] Referring to Figures 1-17, this embodiment provides an elastic module comprising: a first conical elastic unit 1, a transverse connector 3, and a second conical elastic unit 2, arranged sequentially from top to bottom. The first and second conical elastic units 1 and 2 are connected on their smaller sides via a connector 11 and a connector fitting 21, while their larger sides are open. The transverse connector 3 is provided with a clearance opening 31, through which the connector 11 and the connector fitting 21 are connected. The transverse connector 3 connects the elastic assembly formed by connecting multiple first and second conical elastic units 1 and 2 to form a complete elastic module.

[0102] The elastic module is divided into two upper and lower conical elastic units. A connecting structure is provided on the side with the smaller area of ​​the two conical elastic units to achieve mutual connection. The side with the larger area of ​​the two conical elastic units is an open surface. In this way, through the conical setting and the open surface, the same conical elastic units can be stacked together by nesting the open surfaces, thereby realizing the stacking and placement of multiple conical elastic units, which greatly saves the volume for transportation and storage. In addition, this stacking method does not require compression of the elastic units. Even if stored for a long time, the elastic units will not fail or cause accidents due to the sudden release of elastic force by the elastic units.

[0103] In this embodiment, in order to achieve the docking of the first conical elastic unit 1 and the second conical elastic unit 2, the docking method adopted is plugging, that is, the connecting member 11 and the connecting fitting 21 are connected by plugging.

[0104] To this end, the connecting member is a pin 11 provided on the first tapered elastic unit 1, and the connecting mating member is a slot 21 provided on the second tapered elastic unit 2. Furthermore, the slot and pin are tapered. Due to the tapered design, the pin is inserted into the slot with the small end first, thus eliminating the need for strict alignment and allowing the pin to be easily inserted into the slot.

[0105] Referring further to Figure 17 , in this example, to further enhance the connection stability between connector 11 and mating connector 21, the sidewalls of connector 11 and mating connector 21 feature two tapered sections. When plugging pin 11 into slot 21, the less tapered section enters the slot first, followed by the more tapered section. The less tapered section is easier to insert into the slot, while the more tapered section provides a more stable connection. This balances ease of installation with a secure connection.

[0106] In addition, to further enhance the stability and firmness of the connection, the connector 11 and the mating connector 21 are further provided with an additional mating assembly 12 and an additional connector 22, respectively (see Figure 8 ). When the connector 11 is connected to the mating connector 21, the additional mating assembly 12 is connected to the additional connector 22. This creates a plug-in connection, and when the pin is inserted into the slot, the additional connector 22 also inserts into the additional mating connector 21, forming a plug-in connection, further enhancing the stability of the connection.

[0107] In this embodiment, the connector 11 and connector mating member 21, as well as the additional connector 22 and additional connector mating structure 12, are configured as follows. The additional connector mating structure is added to the connector 11. The bottom end of the first tapered elastic unit 1 extends upward to form a first accommodating cavity. The inner wall of the first accommodating cavity 12 extends in the direction of the second tapered elastic unit 2, forming the aforementioned plug-in post 13. An annular groove 12 is formed between the bottom of the first accommodating cavity and the sidewall of the connector 11 at a certain distance to serve as the additional connector mating structure.

[0108] An additional connecting structure 22 is added to the connecting fitting 21, and the top of the slot 21 of the second conical elastic unit extends toward the first conical elastic unit 1 to form an annular boss 22 as the additional connecting fitting 22. The annular boss 22 cooperates with the annular groove 12 to more firmly connect the first and second conical spring units.

[0109] In addition, a limiting member 23 is provided at the bottom of the slot 21, and a limiting latch 13 is provided at the top of the column 11; when the column 11 is plugged into the slot 21, the limiting member 23 is placed in the limiting latch 13 and is limitedly engaged with the limiting latch 13 in the opposite direction of the plugging direction.

[0110] In this embodiment, a base 4 is provided to enhance the stability of the elastic assembly. The side of the second conical elastic unit 2 facing away from the first conical elastic unit 1 is connected to the base 4. In this embodiment, the base 4 is elongated and can connect five second conical elastic units 2, or five elastic assemblies. If more elastic assemblies need to be connected, the system can be expanded by connecting the bases 4 together.

[0111] To facilitate connection and expansion of the base 4, the base 4 is in an elongated shape, with plugs provided on one long side and one short side, and sockets provided on the other long side and the other short side, respectively. This allows expansion by plugging the plugs of one base 4 into the sockets of another base 4.

[0112] In order to fix the second conical elastic unit 2 , the base 4 is provided with a bayonet 41 for inserting the bottom of the second conical elastic unit 2 , and the bottom of the second conical elastic unit 2 is provided with a buckle 24 that cooperates with the bayonet 41 .

[0113] One end of the clip 24 is connected to the second conical elastic unit 2 to form a fixed end, and the other end of the clip 24 is a free end. The side free end of the clip 24 forms a first inclined surface with a gradually increasing thickness toward the fixed end, and the end of the first inclined surface is connected to the first limiting surface.

[0114] The side wall of the bayonet 41 is provided with a second inclined surface which is press-fitted with the first inclined surface, and the end of the second inclined surface is connected to the second limiting surface.

[0115] When the user wants to securely connect the second conical elastic unit 2 to the base 4, they simply press the second conical elastic unit 2 downward, causing the second inclined surface to squeeze the first inclined surface, causing the free end of the buckle 24 to deform. After the second inclined surface and the first inclined surface are released from squeezing, the free end returns to its original position, and the first limiting surface and the second limiting surface are locked in place. The second conical elastic unit 2 is then installed in the base 4.

[0116] In this embodiment, the transverse connecting member 3 is a connecting pad, and the connecting pad is correspondingly provided with a plurality of the clearance openings 31. In this way, the elastic components arranged in an array can be connected together.

[0117] To assemble the elastic module, first connect the second conical elastic unit 2 to the base 4. Then, connect the required bases 4 to each other, completing the arrangement of the base 4 and the second conical elastic unit 2. Then, install the transverse connector 3 on the second conical elastic unit 2. Finally, connect the connecting member 21 of the first elastic unit to the connecting member 11 of the second elastic unit through the clearance opening 31.

[0118] The elastic module obtained in this way can be used in the structures of mattresses, sofas, etc., and it is only necessary to add some soft cushions, cloth covers and other structural parts to the elastic module.

[0119] Example 2

[0120] 18-28 , the difference between this embodiment and embodiment 1 is that the connecting member 11 and the connecting fitting 21 in this embodiment are inserted and rotated, that is, the connecting member 11 is first inserted into the connecting fitting 21 and then rotated a certain angle to achieve the connection between the connecting member 11 and the connecting fitting 21.

[0121] That is to say, the first conical elastic unit 1 has a first position and a second position relative to the second conical elastic unit 2 along the direction of rotational connection. When the first conical elastic unit 1 is in the first position, the first conical elastic unit 1 and the second conical elastic unit 2 release the limiting fit along the direction in which the connecting member 11 is inserted into the connecting fitting 21; when the first conical elastic unit 1 is in the second position, the first conical elastic unit 1 and the second conical elastic unit 2 form a limiting fit along the direction in which the connecting member 11 is inserted into the connecting fitting 21.

[0122] In order to realize this connection structure of first plugging in and then rotating to limit, the connecting fitting 21 is an arc-shaped slot 211 extending in two sections along the rotational connection direction, and the connecting member 11 is a rotating column 111, which includes a first part placed in the arc-shaped slot and a second part passing through the arc-shaped slot; the diameter of one end of the arc-shaped slot is larger than the second part, and the diameter of the other end is smaller than the second part.

[0123] When plugging the connector 11 and the connector fitting 21, the second portion of the rotating post 111 is first inserted into one end of the arc-shaped slot 211. Since the diameter of one end of the arc-shaped slot is larger than the second portion of the rotating post 111, there is no positional fit between the rotating post 111 and the arc-shaped slot 211 along the plugging direction, and the rotating post 111 can be removed from the arc-shaped slot 211. However, when the rotating post 111 is rotated to the other end of the arc-shaped slot 211, since the diameter of this end of the arc-shaped slot 211 is smaller than the second portion of the rotating post 111, the rotating post 111 cannot be removed from this end of the arc-shaped slot 211. In this way, the connector 11 and the connector fitting 21 achieve a positional fit in the direction opposite to the direction in which the connector 11 is inserted into the connector fitting 21.

[0124] Similarly, the first conical elastic unit 1 includes a first accommodating cavity for installing a spring; the connecting member 11 is arranged on the outside of the bottom of the first accommodating cavity. The second conical elastic unit 2 includes a second accommodating cavity for installing a spring; the connecting member 21 is arranged on the top of the second accommodating cavity.

[0125] In this embodiment, the transverse connector 3 comprises a waist connection unit 32 and an intermediate connector 33 connecting two adjacent waist connection units 32. The waist connection units 32 are provided with the clearance openings 31. The intermediate connector 33 is plug-connected to the waist connection units 32. Connecting two adjacent waist connection units 32 together via the intermediate connector 33 can also achieve the same effect.

[0126] In this embodiment, because rotation is required, a bayonet 42 for inserting the bottom of the second conical elastic unit 2 is provided on the base 4 used to fix the base 4 in Example 1, and a plurality of elastic buckles 25 that cooperate with the slots are provided on the bottom of the second conical elastic unit 2 along the circumference.

[0127] One end of the elastic clip 25 is connected to the second conical elastic unit 2 to form a fixed end, and the other end of the clip 24 is a free end, and extends outward along the axial direction perpendicular to the second conical elastic unit 2 to form an insertion part, one side wall of the insertion part forms an inclined surface, and the other side wall forms a limiting surface.

[0128] The inner wall of the bayonet 42 is provided with an annular bayonet groove 43 along the circumference for the insertion portion to be inserted.

[0129] When in use, by inserting the elastic clip 25 into the annular groove 43, the groove wall of the annular groove 43 squeezes the inclined surface to cause the free end to deform until the groove wall of the annular groove 43 separates from the inclined surface, and the limiting surface can cooperate with the annular groove 43 to place the elastic clip 25 in the reversing groove.

[0130] Example 3

[0131] 29-40 , the connecting member 11 and the connecting fitting 21 are rotationally connected. For example, the connecting member 11 and the connecting fitting 21 are rotationally connected via threads.

[0132] Specifically, referring to Figures 37 and 38, the connecting member 11 is an insert ring 112, which has a concave cavity inside and an inner wall thereof with an internal thread 1121; the connecting fitting 21 is a slot with a boss inside the slot and an external thread 212 on the side wall of the boss.

[0133] Similarly, the first conical elastic unit 1 includes a first accommodating cavity for installing a spring; the connecting member 11 is arranged on the outside of the bottom of the first accommodating cavity. The second conical elastic unit 2 includes a second accommodating cavity for installing a spring; the connecting member 21 is arranged on the top of the second accommodating cavity.

[0134] In this embodiment, the transverse connecting member 3 is a waist ring, and the waist rings of adjacent elastic components are connected to each other to form a connecting pad; that is, the intermediate connecting member 33 in Example 2 is eliminated, and the two adjacent waist rings can be directly connected to each other.

[0135] In order to realize the function of the transverse connecting member 3 , the waist ring is provided with the clearance opening 31 , and the connecting member 11 enters the clearance opening 31 and is connected with the connecting fitting 21 .

[0136] To securely connect two waist rings together, the waist rings are provided with locking members 35 along the transverse and longitudinal directions of the array; the locking members 35 are provided with connecting cavities and elastic hooks in sequence along the length direction; the elastic hooks are used to connect and lock with the connecting cavities of adjacent waist rings.

[0137] In order to facilitate unlocking by the user, the elastic hook includes a hook-shaped part and a press-to-unlock part. The press-to-unlock part is exposed outside the waist ring and is used to drive the hook-shaped part to move from the locked position to the unlocked position under the action of external force.

[0138] Different from the long strip base 4 in embodiments 1 and 2, the base 4 in this embodiment is provided in a one-to-one correspondence with the second conical elastic unit 2, and two adjacent bases 4 are connected to each other.

[0139] Furthermore, in this embodiment, the surface of the base 4 is provided with a protrusion 44 that mates with the bottom of the second conical elastic unit 2. The protrusion 44 is provided with a plurality of recesses 45 along the circumference, and the bottom inner wall of the second conical elastic unit 2 is provided with a protrusion 26 that interference fits with the recesses 45. This also achieves a fixed connection between the second conical elastic unit 2 and the surface of the base 4.

[0140] Example 4

[0141] 41-53 , unlike embodiments 1-3, the first elastic unit 1 and the second elastic unit 2 in this embodiment are no longer connected to each other through the transverse connector 3 , but the first single cone 1 and the second elastic unit 2 are respectively connected to the transverse connector 3 .

[0142] Specifically, this embodiment provides an elastic module comprising: a first elastic unit 1, a transverse connector 3, and a second elastic unit 2, arranged sequentially from top to bottom; the bottom ends of the first elastic unit 1 and the top ends of the second elastic unit 2 are respectively connected to the transverse connector 3 to form an elastic assembly; and the transverse connectors 3 of adjacent elastic assemblies are interconnected to form the elastic module. The first elastic unit 1 and the second elastic unit 2 each comprise an upper cover, a bottom cover, and a spring connected between the upper and bottom covers. In this embodiment, the upper cover 15 of the first elastic unit is made of a hard material and is provided with a through hole 152 for connecting an elastic cord. By pulling the upper cover 15 of the first elastic unit 1 toward the bottom cover 14 via the elastic cord, a force is applied to the spring between the upper and bottom covers 15, causing the spring to be pre-compressed. Furthermore, to enhance the comfort of the elastic assembly, a support ring 16 is circumferentially connected to the upper cover 15 of the first elastic unit 1. The support ring 16 protrudes outward from the upper cover 15 along the height direction of the elastic assembly. This prevents the hard cover 15 from directly contacting the user, allowing the flexible support ring 16 to contact the user, improving the user experience. To connect the cover and support ring 16, a raised clip 151 extends circumferentially from the upper surface of the cover, and a circumferential groove 161 is formed on the lower surface of the flexible ring 16.

[0143] By separately connecting the first elastic unit 1 and the second elastic unit 2 to the transverse connector 3, the first elastic unit 1 can be removed from the transverse connector 3 without having to operate the second elastic unit 2. This allows for convenient adjustment of the hardness of each elastic component, and thus the hardness of the entire elastic module. This process is simple and quick, as there is no need to disassemble the second elastic unit 2 and the transverse connector 3.

[0144] Since only the first elastic unit 1 needs to be replaced to adjust the hardness of the elastic module, the connection between the first elastic unit 1 and the transverse connecting member 3 needs to be relatively easy to assemble and disassemble. To this end, the first elastic unit 1 and the transverse connecting member 3 are connected by insertion and rotation to form an easily disassembled connection.

[0145] Specifically, the bottom end of the first elastic unit 1, that is, the bottom cover 14 of the first elastic unit 1, extends downward to form a first protrusion 141. The upper end of the transverse connector 3 is provided with a first recessed portion 34 that accommodates the first protrusion 141. Furthermore, the bottom of the first protrusion 141 extends in the opposite direction to form a second recessed portion 142. The bottom of the first recessed portion 34 also extends in the opposite direction to form a second protrusion 35. The outer wall of the second protrusion 35 and the inner wall of the second recessed portion 142 are respectively provided with a rotating connection member and a rotating connection matching member at intervals along the circumference. Furthermore, the rotating connection member is a protrusion 143 provided on the inner wall of the second recessed portion 142. The protrusion 143 has an open surface 144 along one side of the rotating connection to define a limit slot 145 within the protrusion 143. The rotating connection matching member is a rib 351 provided on the outer wall of the second protrusion 35. When the first protrusion 141 is inserted into the first recess 34, the second protrusion 35 is also inserted into the second recess 142, so that the rib 351 and the protrusion 143 are on the same circumference and staggered. Then, by rotating the first elastic unit 1, the rib 351 can be inserted into the retaining groove 145 along the opening 144 and locked with the retaining groove 145, thus completing the installation of the first elastic unit 1. To remove the first elastic unit 1, simply rotate the first elastic unit 1 in the opposite direction to disengage the rib 351 from the retaining groove 145.

[0146] Because the second elastic unit 2 does not need to be frequently removed from the transverse connector 3, in this embodiment, a plug-in connection is established between the transverse connector 3 and the second elastic unit 2. To achieve this connection, the upper end of the second elastic unit 2, i.e., the upper cover 27 of the second elastic unit 2, is provided with a clearance portion 271 into which the first recess 34 is inserted. Connectors 341 are circumferentially spaced apart on the outer sidewall of the first recess 34, and mating members are provided on the inner sidewall of the clearance portion 271 to mate with the connectors 341.

[0147] In this embodiment, the lower end of the plug connector 341 is formed into an inclined surface 3411, and the mating member is a straight limiting surface 2711. When the first recessed portion 34 is inserted into the clearance portion 271, the inclined surface 3411 compresses against the clearance portion 271, causing the entire first recessed portion 34 to contract radially inward. When the first recessed portion 34 is fully inserted into the clearance portion 271, the inclined surface 3411 separates from the sidewalls of the clearance portion 271, eliminating the compressive force and causing the first recessed portion 34 to expand radially outward. This allows the right-angled surface 3412 on the plug connector 341, which is connected to the inclined surface 3411, to engage with the limiting surface 2711, thus completing the connection between the second elastic unit 2 and the transverse connector 3.

[0148] Finally, in addition to connecting the first elastic unit 1 and the second elastic unit 2, the transverse connector 3 also needs to connect the transverse connectors 3 on adjacent elastic components. Therefore, the transverse connector 3 is provided with a connecting portion and a connecting fitting portion along the circumferential direction; the transverse connectors 3 of adjacent elastic components are connected through the connecting portion and the connecting fitting portion. In this embodiment, the connecting fitting portion is provided with an insertion cavity 37 that is provided along the height direction, and the connecting portion is provided with an insert block 36 for passing through the insertion cavity 37; the insert block 36 is rotated and matched with the transverse connector 3 so that the insert block 36 has a first position and a second position under the action of an external force; when the insert block 36 is in the first position, the insert block 36 and the insertion cavity 37 are limitedly matched against the direction in which the insert block 36 is inserted into the insertion cavity 37; when the insert block 36 is in the second position, the insert block 36 and the insertion cavity 37 are released from the limited fit.

[0149] During installation, the plug block 36 needs to be adjusted to the second position and placed at the lower part of the insertion cavity 37, and then the plug block 36 is inserted into the insertion cavity 37 from bottom to top, so that the plug block 36 passes through the insertion cavity 37 as a whole and is exposed above the insertion cavity 37, and then the plug block 36 is rotated so that it is located in the first position. Since the length of the insertion cavity 37 is greater than the width, when the plug block 36 is rotated, the long axis of the plug block 36 rotates to the short axis of the insertion cavity 37, so that the plug block 36 and the insertion cavity 37 can form a limited fit.

[0150] This embodiment further provides an elastic pad, comprising the elastic module as described above, an additional surface layer 5 and a bottom plate 4 , wherein the second elastic unit is connected to the bottom plate 4 , so that the elastic component array is arranged on the bottom plate 4 .

[0151] To connect the second elastic unit 2 to the bottom plate 4, a bottom cover 28 is connected to the side of the second elastic unit 2 facing away from the first elastic unit 1. This bottom cover 28 is circumferentially provided with an annular groove 281, with the bottom edge of the second elastic unit 2 engaging with this annular groove 281. Furthermore, the side of the bottom cover 28 facing away from the transverse connector 3 is recessed toward the transverse connector 3 to form an inner cavity 282. The sidewall of this inner cavity 282 is circumferentially provided with at least one limiting groove 283, which is open along one side of the circumference.

[0152] The bottom plate 4 is provided with a convex bump 46 that cooperates with the inner concave cavity 282. The outer side of the convex bump 46 has a limiting rib 461 that cooperates with the limiting groove 283. When the bottom cover 28 of the second elastic unit is installed with the bottom plate 4, the convex bump 46 enters the inner concave cavity 282, and the limiting rib 461 and the limiting groove 283 are located on the same circumference and outside the limiting groove 283. When the elastic component is rotated, the limiting rib 461 enters the limiting groove 283 from the opening and cooperates with the limiting groove 283 in the direction opposite to the insertion of the convex bump 46 into the inner concave cavity 282, thereby completing the fixing of the elastic component. When the elastic component is to be disassembled, it is only necessary to rotate the elastic component in the opposite direction so that the limiting rib 461 is removed from the limiting groove 283.

[0153] Example 5

[0154] Referring to Figure 54 , this embodiment differs from Example 4 in that the opening edge of the first elastic unit 1, facing away from the second elastic unit 2, is fixed to a support ring 16. The support ring 16 supports the upper edge of the first elastic unit 1. The upper cover in Example 4 is omitted. Instead, the support ring 16 and the cloth cover 17 of the first elastic unit 1 are directly sewn together.

[0155] Example 6

[0156] Referring to Figure 55 , this embodiment differs from Example 6 in that the upper cover 15 of the first elastic unit in Example 4 is made of an elastic material instead of a hard material, and the through-hole in the upper cover 15 of the first elastic unit in Example 4 is eliminated. Because the upper cover 15 itself is also made of an elastic material, the support ring 16 does not need to protrude from the upper cover 15; it can wrap around the side of the upper cover 15 and be directly sewn to the cloth cover 17 of the first elastic unit 1.

[0157] Example 7

[0158] Referring to Figures 56-58 , this embodiment differs from Example 4 in that the side of the bottom cover 28 of the second elastic unit facing away from the transverse connector 3 is recessed toward the transverse connector 3 to form an inner cavity 21. However, the sidewalls of the inner cavity 281 are no longer provided with a limiting groove. The elastic assembly is mounted to the base plate 4 using an interference fit between the convex bump 46 and the inner cavity 281.

[0159] 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. Industrial Applicability

[0160] The present invention provides an elastic module, which is divided into two upper and lower conical elastic units. The two elastic units are connected to each other by connecting structures at their upper and lower ends. The larger side of the two conical elastic units is an open surface. Due to the conical configuration and the open surface, similar conical elastic units can be stacked together by nesting the open surfaces, thereby enabling the stacking of multiple conical elastic units, significantly reducing the volume for transportation and storage. Furthermore, this stacking method does not require compression of the elastic units, and even during long-term storage, there is no risk of elastic unit failure or accidents caused by the sudden release of elastic force from the elastic units. Because the first and second elastic units are disconnectable, when the hardness of the elastic pad needs to be adjusted, the hardness of the elastic pad can be adjusted by simply replacing the first elastic unit on the side in contact with the human body. Furthermore, when removing the first elastic unit, there is no need to disassemble the transverse connector, making it very convenient to adjust the hardness of the elastic pad. The invention has good industrial applicability.
