[0067] refer to Figures 1-24 This embodiment provides a spring unit splicing module for inverted camping mats. The spring unit splicing module is composed of several individual spring modules 1. Each individual spring module 1 is provided with a third part 2. The third part 2 is an independent part or is provided integrally with the individual spring module 1.

[0068] The individual spring module 1 consists of a conical spring sleeve 11 and a conical spring 12 built into the conical spring sleeve 11. Several individual spring modules 1 are spliced ​​together in pairs by a third piece 2 to form a spring pad 6. The spring pad 6 serves as the main support for the camping mat 9. A soft padding layer 7 is laid on the spring pad 6 to make it a camping mat 9, providing users with a comfortable rest.

[0069] The connection between the two third pieces 2 between the two individual spring modules 1 is configured as a detachable connection, and the two third pieces 2 can be connected by a detachable snap-fit. The individual spring module 1 is a conical structure, with its large conical end serving as the main pressure-bearing end and a lying support surface, increasing the force-bearing area and providing better stability and comfort. To ensure the connection stability and force stability of the spring pad 6, the third piece 2 is mainly located at any position in the area from the waist to the large end of the conical spring sleeve 11, that is, in the area of ​​one-third of the height of the individual spring module 1, which is located near the large end.

[0070] The third component 2 includes a first connector 4 and a second connector 5, which are connected by a detachable snap-fit. The snap-fit ​​structure 41 between the first connector 4 and the second connector 5 enables quick assembly and simple operation, making the spring pad 6 easy to assemble and disassemble. This facilitates quick assembly and disassembly for users in camping settings, meeting the convenience requirements for outdoor use.

[0071] First embodiment, reference Figures 1-8 .

[0072] The third component 2 is set at the waist of the single spring module 1. The third component 2 includes a retaining ring 21 and a pull bar 22. The retaining ring 21 is connected to the waist of the tapered spring sleeve 11. The pull bar 22 is set to 4 bars, which are arranged around the retaining ring 21 and the 4 pull bars 22 are evenly spaced.

[0073] A first connector 4 and a second connector 5 are arranged along the length of a single pull bar 22, with the first connector 4 located on the outer side and at the end of the pull bar 22. Each of the four sides of a single spring module 1 is spliced ​​to another single spring module 1 via a pull bar 22.

[0074] The pull strip 22 has a certain length and can extend outward relative to the retaining ring 21, facilitating the fastening operation between two pull strips 22. The first connecting member 4 is configured as a buckle 41, and the second connecting member 5 is configured as a retaining groove 51. The buckle 41 and the retaining groove 51 form a buckle 41 connection, and the buckle 41 is an elastic buckle 411. Pressing the buckle 41 inward can release it from the retaining groove 51.

[0075] A buckle 41 is provided on one side of the pull bar 22, and the side facing away from the buckle 41 is the insertion side. When the two pull bars 22 are fastened to the slot 51 by the buckle 41, the insertion is performed from the insertion side, which can avoid the buckle 41 interfering with the buckle 41 on the side of the slot 51.

[0076] The buckle 41 has a U-shaped or V-shaped relief groove 412 in the middle, which forms two locking feet on both sides of the buckle 41. An inclined surface 413 is provided at the end of the locking feet on both sides, and a boss 414 is provided below the inclined surface 413. When the buckle 41 is inserted into the corresponding slot 51 along the insertion side, the locking feet on both sides press against the inner opening of the slot 51 with the inclined surface 413 at their ends. With the relief groove 412 providing clearance, the two locking feet move closer to each other, forming an inward retraction that allows the buckle 41 to be inserted into the slot 51.

[0077] When the inclined surface 413 is inserted into and then extends out of the slot 51, the inclined surfaces 413 on both sides lose their compression, and the two locking feet open to the sides under the elastic force, so that the protrusion 414 below the inclined surface 413 is locked on the edge of the slot 51, thus forming a fastening connection. When disassembly is required, simply squeeze the locking feet on both sides to retract them, the protrusion 414 disengages from the edge of the slot, and then squeeze the buckle 41 towards the slot to disengage the buckle 41 from the slot 51, thereby releasing the connection between the two individual spring modules 1.

[0078] In this embodiment, each individual pull bar 22 is provided with a first connector 4 and a second connector 5, allowing for arbitrary splicing without angle or direction restrictions when multiple individual spring modules 1 are assembled, thus achieving splicing convenience. Alternatively, each individual pull bar 22 may only have a first connector 4 or a second connector 5, with the first connector 4 and second connector 5 alternately arranged along the waist retaining ring 21 of each individual spring module 1, simplifying the structure of the pull bar 22 while still enabling the splicing of two individual spring modules 1 together.

[0079] In this embodiment, the third component 2 has two specifications: a wide pull strip 23 structure and a narrow pull strip 24 structure, wherein the retaining ring 21 has the same width as the pull strip 22. The width of the pull strip 22 can be set according to the splicing area of ​​the spring pad 6. The wide pull strip 23 structure can provide a more stable connection, while the narrow pull strip 24 structure can provide softer and more comfortable support.

[0080] Second embodiment, reference Figures 9-12 .

[0081] A third component 2 is disposed at the large end of the single spring module 1. The third component 2 includes a first connector 4 and a second connector 5. The first connector 4 and the second connector 5 are arranged circumferentially along the large end face of the tapered spring sleeve 11, and the first connector 4 and the second connector 5 are arranged alternately.

[0082] The first connector 4 includes a U-shaped retaining edge 42 and an elastic protrusion 43 disposed within the U-shaped retaining edge 42. The second connector 5 includes an insertion groove 52 and a retaining opening 53 communicating with the insertion groove 52. In order to facilitate the elastic protrusion 43 to engage with the retaining opening 53 and to prevent the elastic protrusion 43 from protruding too much from the retaining opening 53 after engagement, thus causing unstable connection, this embodiment provides a protruding edge 431 on the elastic protrusion 43. When the elastic protrusion 43 springs up and engages with the retaining opening 53, the protruding edge 431 abuts against the lower edge of the retaining opening 53, thus playing a limiting role.

[0083] When two individual spring modules 1 are joined together, the first connector 4 of one individual spring module 1 connects to the second connector 5 of the other individual spring module 1. The U-shaped locking edge 42 of the first connector 4 is inserted into the insertion groove 52 of the second connector 5. Under the pressure of the groove opening 52, the elastic protrusion 43 of the first connector 4 deforms downward, allowing the U-shaped locking edge 42 to gradually insert into the insertion groove 52. When it is inserted to a certain position, and the elastic protrusion is below the locking opening 53, the elastic protrusion 43 springs up and locks into the locking opening 53, thus forming a fastening connection. When disassembly is required, simply press the elastic protrusion 43 downward to disengage it from the locking opening 53, and then pull the first connector 4 outward to detach it from the second connector 5, thereby releasing the connection between the two individual spring modules 1.

[0084] Third embodiment, reference Figures 13-17 .

[0085] The third piece 2 is set at the large end of the single spring module 1, and four connection positions are equally spaced along the circumferential direction of the large end face of the tapered spring sleeve 11. Each connection position is provided with a third piece 2, which includes a first connecting piece 4 and a second connecting piece 5.

[0086] The first connector 4 has a socket 44 and a locking piece 45 is provided inside the socket 44. The second connector 5 has a plug 54 and a fastener 55 is provided on the plug 54. When the plug 54 is inserted into the socket 44, the locking piece 45 and the fastener 55 form a snap-fit ​​connection 41, which prevents the plug 54 from being pulled out of the socket 44, thereby forming a fastening connection.

[0087] The specific structure is as follows: a second elastic element 56 is provided on the large end face of the tapered spring sleeve 11 connected to one side of the insert 54. The second elastic element 56 is connected to the fastener 55, and a limiting groove is provided on one side of the insert 54. The limiting groove provides space for the fastener 55 to retract. One end of the fastener 55 extends into the limiting groove, and a protrusion 551 is provided on the end of the fastener 55 extending into the limiting groove. A clearance opening is provided on one side of the insertion port 44, and a step is provided on the inner side of the clearance opening.

[0088] When two individual spring modules 1 are spliced ​​together, the first connector 4 of one individual spring module 1 mates with the second connector 5 of the other individual spring module 1. The insert 54 of the first connector 4 is inserted into the socket 44 of the second connector 5. The clearance opening on the socket 44 creates clearance for the fastener 55, facilitating the further insertion of the insert 54. As the insert 54 continues to be inserted into the socket 44, the slope on the inner side of the clearance opening presses against the protrusion 551 on the fastener 55, causing the fastener 55 to deform inward, thereby facilitating the insertion of the insert 54.

[0089] When inserted to a certain position, the slope on the inner side of the clearance opening misaligns with the protrusion 551 on the fastener 55. Under the action of the second elastic member 56, the fastener 55 springs up, and its protrusion 551 locks onto the step, thus forming a fastening connection. When disassembly is required, simply press the second elastic member 56 inward to disengage the protrusion 551 of the fastener 55 from the step, and then pull out the first connecting member 4 to disengage from the second connecting member 5, thereby releasing the connection between the two individual spring modules 1.

[0090] Fourth embodiment, reference Figures 18-20 .

[0091] The third piece 2 is set at the large end of the single spring module 1, and four connection positions are equally spaced along the circumferential direction of the large end face of the tapered spring sleeve 11. Each connection position is provided with a third piece 2, which includes a first connecting piece 4 and a second connecting piece 5.

[0092] The first connector 4 has a socket 44 and a locking piece 45 is provided inside the socket 44. The second connector 5 has a plug 54 and a fastener 55 is provided on the plug 54. When the plug 54 is inserted into the socket 44, the locking piece 45 and the fastener 55 form a snap-fit ​​connection 41, which prevents the plug 54 from being pulled out of the socket 44, thereby forming a fastening connection.

[0093] The specific structure is as follows: a first elastic element 46 is provided on the large end face of the tapered spring sleeve 11 on one side of the socket 44. The first elastic element 46 is connected to the locking element 45, and the locking element 45 is provided to protrude inward on the inner side of the socket 44. A fastener 55 is provided to be recessed on one side of the plug block 54.

[0094] When two individual spring modules 1 are joined together, the first connecting piece 4 of one individual spring module 1 aligns with the second connecting piece 5 of the other individual spring module 1. The insert 54 of the first connecting piece 4 is inserted into the socket 44 of the second connecting piece 5. Under the pressure of the insert 54, one side of the socket 44, in conjunction with the first elastic member 46, deforms outward, creating space to facilitate further insertion of the insert 54. When inserted to a certain position, the locking piece 45 and the fastener 55 are aligned. The locking piece 45, under the action of the first elastic member 46, locks inward onto the fastener 55, thus forming a fastening connection. When disassembly is required, simply pull out the second elastic member 56 to disengage the locking piece 45 from the fastener 55, and then pull out the first connecting piece 4 to detach from the second connecting piece 5, thereby releasing the connection between the two individual spring modules 1.

[0095] Fifth embodiment, reference Figures 21-24 .

[0096] A camping mat 9 is provided, which uses an inverted spring unit splicing module.

[0097] The system includes a spring pad 6, a soft padding layer 7, and a bottom support 8. The spring pad 6 serves as the main support for the camping mat 9 and is composed of several individual spring modules 1 joined together in pairs via a third component 2.

[0098] The bottom bracket 8 has an upwardly protruding plug-in part 81, and the bottom of the tapered spring sleeve 11 of the single spring module 1 has a groove 13. The single spring module 1 is flipped by interlocking the groove 13 with the plug-in part 81.

[0099] In this embodiment, the bottom support 8 is composed of multiple sets of frames that are interlocked in pairs, and the frames are configured to be detachable. The frames are configured to have at least one folding structure along their length, which can be used for folding and storage.
