DETAILED DESCRIPTION

[0056] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0058] In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. 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. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0059] refer to Figure 1-Figure 24 This embodiment provides a spring module 3 structure with a single spring installed, and a plurality of the spring modules 3 are used to be assembled in sequence to form an elastic pad. The spring module 3 includes a connecting base 1 and a plurality of elastic modules 2 assembled on the connecting base 1.

[0060] The connecting base 1 includes a first base 12 and a second base 13. The first base 12 and the second base 13 are connected at one side of their ends with a rotating hinge 14. The rotating hinge 14 allows the first base 12 and the second base 13 to form a relative folding or relative unfolding movement. When folding, the long side of the connecting base 1 is folded in half to reduce the space occupied by the long side. When storing, the foldable storage space is small and convenient for storage. On the other hand, the length of the connecting base 1 is reduced to avoid partial breakage during transportation due to excessive length.

[0061] In order to better maintain the relative folding and relative unfolding state of the connecting base 1, the first base 12 and the second base 13 are arranged opposite to each other at the end of the hinge 14 relative to the side of the hinge 14 to form a first clamping piece 18 for engagement; and at the same time, the first base 12 and the second base 13 are arranged opposite to each other on the sides thereof formed by rotation and on the sides thereof formed by rotation away from each other to form a second clamping piece 19 for engagement.

[0062] The specific operation is that the connecting base 1 is constructed with the rotating hinge 14 so that the first base 12 and the second base 13 can be releasably engaged with the second clip 19 on the splicing side; or the connecting base 1 is constructed with the rotating hinge 14 so that the first base 12 and the second base 13 can be releasably engaged with the first clip 18 on the rotating end, at this time, the connecting base 1 is constructed to be releasably engaged with the adjacent connecting base 1 with the second clip 19.

[0063] like Figure 1-3 As shown, Figure 2 The unfolding process of the spring module 3 shown in the figure is mainly, when the connection base 1 assembled with the elastic module 2 rotates around the rotating hinge 14 with the first base 12 and the second base 13, the long side of one of the bases is rotated to abut against the long side of the other base, based on the long side of the first base 12 or the second base 13, at this time, the second clamping piece 19 on the abutting splicing side is engaged, and the connection base 1 is folded and stored; when the connection base 1 assembled with the elastic module 2 rotates around the rotating hinge 14 with the first base 12 and the second base 13, the long side of one of the bases is rotated to abut against the long side of the other base, and the second clamping piece 19 on the abutting splicing side is engaged, and the connection base 1 is folded and stored; When rotating, the short side of the first base 12 or the second base 13 (that is, the short side where the rotating end is located) is used as the reference, and the short side of one of the bases is rotated until it is against the short side of the other base. At this time, the first clip 18 on the abutting short side is engaged, and the connecting base 1 is unfolded; when the connecting base 1 is unfolded, the role of the second clip 19 is changed to realize the splicing and snapping action of the elastic pad, and the second clip 19 on one connecting base 1 is engaged with the corresponding second clip 19 on the other connecting base 1 to realize splicing.

[0064] In this embodiment, the folding and unfolding structure of the spring module 3 is also equipped with a locking structure, which includes a rotating clamp 31 and a joint member 32 which are arranged on both sides of the end of the spring module 3 and can form a mutual engagement. The rotating clamp 31 is arranged to be able to swing back and forth around the pivot axis to releasably engage with the joint member 32 opposite to it, and the joint member 32 is arranged to be able to releasably engage with the relative rotating clamp 31. Specifically, it is arranged on one end of the first base 12 and the second base 13 relative to its rotation hinge 14. The first base 12 and the second base 13 are both arranged on both sides of their respective ends, one side of which is provided with a rotating clamp 31, and the other side of which is provided with a joint member 32. The position relationship is that when the first base 12 and the second base 13 are relatively folded, the rotating clamp 31 of one of the first base 12 and the second base 13 can be relatively engaged with the joint member 32 of the other base to form a lock.

[0065] The setting of the locking structure is used, on the one hand, to lock the first base 12 and the second base 13 after the first base 12 and the second base 13 are relatively folded when a connection base 1 is folded and stored, and on the other hand, to lock the connection bases 1 when multiple splicing is performed when the connection base 1 is unfolded. Under the setting of the locking structure, the first clamping member 18 and the second clamping member 19 are provided to serve as pre-positioning.

[0066] It should be noted that the first clamping member 18 and the second clamping member 19 can be of various types, and no matter what type of pre-positioning structure is adopted, as long as the adjacent bases can be pre-positioned. In this embodiment, the first clamping member 18 and the second clamping member 19 both include two pre-positioning structures with different structures. Specifically, in the first clamping member 18 and the second clamping member 19, one of them is set as a retractable elastic protrusion, and the other is set as a recess that can accommodate the elastic protrusion. After the elastic protrusion and the recess are aligned in the lateral direction, the balance of the pre-positioning of the adjacent bases can be further improved. Or the first clamping member 18 and the second clamping member 19 can adopt a hook and slot 15 structure that can be engaged.

[0067] The connection base 1 assembled with the elastic module 2 mentioned in this embodiment is referred to as Figure 4-12 , its assembly structure is:

[0068] The first base 12 and the second base 13 are provided with a slot 15 that can be slidably connected with the elastic module 2. The slot 15 limits the elastic module 2 from separating from the base in the vertical direction. The first base 12 and the second base 13 have one end as a sliding entrance 16 for the elastic module 2, and a limiting structure is provided near the sliding entrance 16 and corresponding to the location of the first elastic module 2. The limiting structure is used to limit the elastic module 2 from sliding out of the sliding entrance 16.

[0069] The assembly sequence is that when the connecting base 1 is in a folded storage state, a single elastic module 2 is assembled. Assembling in the folded storage state can better operate the sliding connection of the elastic module 2 to the slot 15, and the long sides can interact with each other to avoid damage to the connecting base 1 caused by jamming and force during the assembly process.

[0070] like Figure 6 A sliding entrance 16 is provided at one end of the base 1 connected to set the rotating hinge 14, and is sealed with a card slot 15 at the end away from the rotating hinge 14. In this embodiment, four assemblies of a single-side base are taken as an example, and are assembled in sequence from the sliding entrance 16. When the fourth one is assembled, the fourth elastic module 2 is clamped near the sliding entrance 16 and the elastic module 2 is limited by the limiting structure, so that it is fixed at the sliding entrance 16 and completes the limitation of the remaining three elastic modules 2 by its own limitation.

[0071] In this embodiment, a sliding entrance 16 is provided at one end of the connecting base 1 where the rotating hinge 14 is provided, so that when the connecting base 1 is unfolded, the two sliding entrances 16 form a relative limit, thereby further completing the limit of the elastic module 2.

[0072] like Figure 11-12 The sliding connection structure connecting the base 1 and the elastic module 2 is that C-shaped slots 15 with opposite notches are set on both side edges of the first base 12 and the second base 13; the spring fixing seat 21 of the elastic module 2 is clamped along its edge in the C-shaped slot 15 to form a limit.

[0073] like Figure 7-10 The limiting structure is configured as a raised portion 17 formed by the base body being inclined and higher than the base sliding surface as the limiting structure; the spring fixing seat 21 of the elastic module 2 is formed by its fixing seat body with a recessed portion 221 suitable for receiving the raised portion 17.

[0074] Furthermore, the protrusion 17 is configured as an elastic sheet with an inclined surface, and the inclination angle of the inclined surface gradually tilts upward along the insertion direction of the elastic module 2, so as to form a releasable mutual engagement with the recessed portion 221 to form a limit; when the elastic module 2 is inserted into the slot 15 along the insertion direction, the elastic module 2 is moved inward along the length direction of the slot 15 until it reaches a specified position, and when the elastic module 2 moves inward from the sliding entrance 16, the sliding surface of the spring fixing seat 21 of the elastic module 2 slides and squeezes the elastic sheet downward to make way, thereby ensuring the sliding of the elastic module 2 along the insertion direction. However, when the elastic module 2 needs to slide against the insertion direction, it will be limited by the engagement between the elastic sheet and the recessed portion 221. The setting position of the elastic sheet is just plugged into place when the last elastic module 2 is inserted into the sliding entrance 16, and the elastic sheet is just engaged with the recessed portion 221 of the last elastic module 2.

[0075] The structure for releasing the limit structure is as follows: Fig.10 A pressing portion 171 is provided on a side of the elastic sheet away from the sliding surface of the base, for pushing the limiting member out of the recessed portion 221 to release the limiting.

[0076] In this embodiment, the provided connection base 1 and elastic module 2 and the spring module 3 after the connection base 1 and the elastic module 2 are spliced ​​can be stacked in multiples, such as Figure 14-17 .

[0077] The elastic module 2 includes a spring fixing seat 21 and a spring sleeve 22 that are engaged with each other. The spring sleeve 22 is configured to accommodate a conical spring 23 therein; the spring sleeve 22 has a cavity for stacking another spring sleeve 22, and the spring fixing seat 21 corresponds to the cavity opening to allow another spring sleeve 22 to be stacked.

[0078] Due to the conical structure of the conical spring 23, conical stacking can be achieved. In this embodiment, the spring fixing seat 21 is opened with a maximum diameter corresponding to the conical spring 23, and a conical cavity is set in the spring sleeve 22 corresponding to the middle cavity structure of the conical spring 23, and the spring sleeves 22 are inserted and stacked through the set opening.

[0079] The connection base 1 is provided with a plurality of through holes 11 corresponding to the elastic module 2, and the through holes 11 provided on the connection base 1 are adapted to the openings of the spring fixing seat 21, so that two or more spring modules 3 can be stacked. The through holes 11 provided on the connection base 1 can realize that multiple stacking can still be achieved after the connection base 1 and the elastic module 2 are spliced.

[0080] With the stackable structure, when disassembling and transporting, the whole can be broken down into parts to reduce the space occupied. In the initial installation state, the base 1 and the elastic module 2 can be independently stacked and transported, which is convenient for transportation and sale. The independent connection between the base 1 and the elastic module 2 can realize the replacement of damaged individual parts. When it is necessary to disassemble and transport again, the base 1 and the elastic module 2 can be connected to complete the splicing of the spring module 3 for stacking and transportation, which can realize rapid disassembly and transportation and rapid assembly and use, saving time and effort.

[0081] The spring cover 22 in the elastic module 2 for accommodating the conical spring 23 includes a plastic spring cover 22 and a cloth-wrapped spring cover 22. Figure 1-17 In the figure, the plastic spring sleeve 22 is used as a structural diagram. Figure 18-22 The cloth bag spring cover 22 is mainly used.

[0082] First embodiment, reference Figure 18-22 , mainly based on the bag spring sleeve 22, provides an elastic pad formed by splicing and assembling multiple spring modules 3 described in the above embodiment.

[0083] In this embodiment, a spring module 3 assembled with a bag spring sleeve 22 is provided. When the spring module 3 is unfolded, Fig.19, the second clamping piece 19 on one side of the connecting base 1 is used as a pre-positioning for splicing, so that when the spring module 3 is assembled into the spring pad 4, the plurality of spring modules 3 are positioned and plugged with the second clamping pieces 19 corresponding to the connecting bases 1 in pairs, and the splicing sides of the connecting bases 1 are spliced ​​in sequence, and the two adjacent connecting bases 1 are locked and connected together by the engagement of the rotating clamps 31 and the engaging pieces 32. When all the connecting base plates have completed the locking of the rotating clamps 31 and the engaging pieces 32 in pairs, the plurality of spring modules 3 are assembled into the elastic support layer of the elastic pad. The splicing method provided in this embodiment can significantly improve the convenience of assembling the elastic pad, and is easy to disassemble for storage, effectively reducing the space occupied by the elastic pad when it is stored.

[0084] like Fig. 20 In this embodiment, the rotating clamp 31 includes a hook 311 and a hook, and the engaging member 32 includes a receiving groove and a clamping column arranged in the receiving groove. In this way, when the rotating clamp 31 rotates, the hook is placed in the receiving groove and engages with the clamping column to achieve connection locking. When the rotating clamp 31 rotates in the opposite direction, the hook and the clamping column are released to achieve unlocking.

[0085] The second embodiment, referring to Figure 23-24 , based on the elastic pad of the first embodiment, a soft pad 7 is provided, which can be used for furniture.

[0086] The soft pad 7 includes an elastic pad and a flexible pad layer 5 and a cloth cover 6 are laid on the elastic pad in sequence. The flexible pad layer 5 has a skirt with a hanging strap 51; the rotating clamp 31 includes a hanging ear 311, which is used to cooperate with the hanging strap 51 to fix the flexible pad layer 5. In this embodiment, the structure of the hanging ear 311 can be used to hang the hanging strap 51 to complete the assembly of the soft pad 7, and can also be used for hand-held operation. The rotating clamp 31 is rotated by the hanging ear 311 to engage or disengage the hook with the clamping column, which is convenient for effective assembly and portable disassembly.

[0087] The above is only a preferred specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the 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 protection scope of the present invention.
