[0044] The present application provides a technical solution:

[0045] As Figure 1 , Figure 2 and Figure 3As shown, a multipurpose lifesaving net includes: a net body 1, a net splicing assembly, a splicing assembly locking mechanism and a connecting locking assembly, one side of the net body 1 is fixedly provided with a net support column 11, the other side is fixedly provided with a net hollow support column 12, the net body 1 is supported by the net support column 11 and the net hollow support column 12, and the net support column 11 and the net hollow support column 12 are both cylindrical, facilitating personnel to grasp, the net splicing assembly is installed on the net support column 11, the net body 1 is spliced together through the net splicing assembly, when in actual rescue work, when the distance of the fallen person is far or the number of fallen persons is large, the overall length of the net can be made longer through splicing to meet the rescue demand, the splicing assembly locking mechanism is installed on the net splicing assembly, used for locking the net splicing assembly, thereby ensuring the stability of the net splicing assembly, the connecting locking assembly is installed on the net hollow support column 12, used for locking between the net body 1, and the connecting locking assembly is driven by the splicing assembly locking mechanism, so that the net splicing assembly on one net body 1 will not be separated from another net body 1, ensuring the stability of the connection between the net body 1.

[0046] As Figure 1 , Figure 2 , Figure 4 and Figure 7 shown, the net splicing assembly includes: a rotating drive rod 2, a splicing connecting strip 3 and a limiting half ring sleeve 5, an installation cavity 13 is formed on the net support column 11, the rotating drive rod 2 is inserted into the installation cavity 13, and a support through hole 17 is further formed in the cavity bottom of the installation cavity 13, the rotating drive rod 2 is inserted into the support through hole 17, and the rotating drive rod 2 is supported by the cooperation of the rotating drive rod 2 and the support through hole 17.

[0047] The splicing connecting strip 3 is also inserted into the installation cavity 13, and a moving channel 16 is further formed on the net support column 11, the moving channel 16 is in communication with the installation cavity 13, and the splicing connecting strip 3 is partially inserted into the moving channel 16.

[0048] As Figure 7 , Figure 9 and Figure 10As shown, the spliced connecting strip 3 is movably connected with the rotary driving rod 2, and the spliced connecting strip 3 is moved by the rotary driving rod 2. Specifically, a connecting slot 31 is symmetrically formed at the upper and lower ends of the spliced connecting strip 3, the inner wall of the connecting slot 31 is smooth without burrs, a fixing groove 32 is formed on one side of the spliced connecting strip 3, a plurality of support lugs 33 are welded and fixed on the other side, the specific number can be set according to actual use requirements, each group of support lugs 33 is two, a support connecting rod 34 is welded and fixed on the support lug 33, a plurality of eccentric connecting blocks 21 are welded and fixed on the rotary driving rod 2, the number of the eccentric connecting blocks 21 is equal to the number of the groups of support lugs 33, one eccentric connecting block 21 is between the two support lugs 33 in a group, a connecting ring 22 is symmetrically formed on the eccentric connecting block 21, the inner wall of the connecting ring 22 is smooth without burrs, and the support connecting rod 34 is inserted into the connecting ring 22, the support connecting rod 34 is in contact with the inner wall of the connecting ring 22. When the rotary driving rod 2 rotates, the spliced connecting strip 3 can be moved under the cooperation of the connecting ring 22 and the support connecting rod 34.

[0049] As shown in Figure 1 , Figure 4 , Figure 11 and Figure 12 , the limiting half ring sleeve 5 is fixedly installed at one end of the net hanging column 11. Specifically, an internal protrusion 14 is symmetrically and integrally formed inside one end of the net hanging column 11, a first threaded hole 15 is formed on the internal protrusion 14, the limiting half ring sleeve 5 is two, and is symmetrically sleeved on the net hanging column 11, and a support lug 52 is integrally and fixedly arranged at the upper end of the limiting half ring sleeve 5, a matching insertion hole 53 is formed on the support lug 52, and a screw 54 is inserted into the matching insertion hole 53. Specifically, when the limiting half ring sleeve 5 is fixed, the limiting half ring sleeve 5 is sleeved on the net hanging column 11, so that the matching insertion hole 53 is aligned with the first threaded hole 15, and then the screw 54 is threadedly connected in the first threaded hole 15 through the matching insertion hole 53, so that the fixing of the limiting half ring sleeve 5 is realized. When the two limiting half ring sleeves 5 are installed on the net hanging column 11, they are closed together.

[0050] As shown in Figure 4 , Figure 5 and Figure 6 , a column lug 121 is symmetrically and integrally formed at the two ends of the net hanging hollow column 12, a communication insertion hole 122 is formed on the column lug 121, the communication insertion hole 122 penetrates the net hanging hollow column 12, and a matching guide hole 123 is symmetrically formed on one end of the net hanging hollow column 12. In addition, a connecting channel 124 is formed on the net hanging hollow column 12, and a connecting strip 125 is symmetrically welded and fixed in the connecting channel 124.

[0051] When splicing two net bodies 1, the splicing connecting strip 3 on one of the net bodies 1 protrudes out of the outside of the net support column 11 and is inserted into the hollow net support column 12 on the other net body 1. The connection between the net bodies 1 is achieved through the splicing connecting strip 3, and the connecting support strip 125 is inserted into the connecting slot 31 on the splicing connecting strip 3.

[0052] like Figure 1 , Figure 7 , Figure 9 and Figure 11 As shown, the limiting semi-ring sleeve 5 cooperates with the rotating drive rod 2 to limit its movement. Specifically, a rotating bearing plate 23 is welded and fixed to one end of the rotating drive rod 2. A rotating ring channel 24 is formed on the rotating bearing plate 23, and the rotating bearing plate 23 is located outside the mounting cavity 13. The inner wall of the rotating ring channel 24 is smooth and burr-free. A limiting semi-ring plate 51 is integrally formed inside the limiting semi-ring sleeve 5. The limiting semi-ring plate 51 is inserted into the rotating ring channel 24 on the rotating bearing plate 23 and contacts the inner wall of the rotating ring channel 24. Through the cooperation of the rotating ring channel 24 and the limiting semi-ring plate 51, the rotating drive rod 2 can be restricted in the hanging net support column 11. The rotating drive rod 2 can rotate. In addition, when the two limiting semi-ring sleeves 5 are closed together, an anti-rotation channel 55 is formed between them.

[0053] like Figure 7 , Figure 8 and Figure 9 As shown, the splicing component locking mechanism includes: a threaded rod 29, a locking support strip 4, and a movable insert rod 44. The threaded rod 29 is threadedly installed on the rotary drive rod 2. Specifically, a support rod 25 is symmetrically welded and fixed on the rotary support plate 23, and a support strip 26 is welded and fixed on the support rod 25. An extension support plate 27 is symmetrically integrally formed on the support strip 26, and a mating strip 28 is integrally formed at the end of the extension support plate 27. An insertion channel 281 is opened on the mating strip 28, and a second threaded hole 282 is also opened on the mating strip 28. The second threaded hole 282 communicates with the insertion channel 281, and the threaded rod 29 is threadedly connected in the second threaded hole 282.

[0054] The locking support bar 4 is installed on the rotary drive rod 2. Specifically, a guide block 41 is integrally formed symmetrically on the locking support bar 4. A connecting guide hole 42 is opened on the guide block 41. A support rod 25 is inserted into the connecting guide hole 42. The locking support bar 4 is installed on the rotary drive rod 2 through the cooperation of the connecting guide hole 42 and the support rod 25.

[0055] The movable insert rod 44 is movably installed on the locking support bar 4. Specifically, the locking support bar 4 has a movable channel 43, the movable insert rod 44 is inserted into the movable channel 43, and the movable insert rod 44 is symmetrically sleeved with a first spring 48.

[0056] By cooperating with the locking support bar 4 and the limiting semi-ring sleeve 5, the locking support bar 4 is inserted into the anti-rotation channel 55 formed by the two limiting semi-ring sleeves 5, and the locking support bar 4 is in contact with the inner wall of the anti-rotation channel 55. Thus, under the restriction of the anti-rotation channel 55, the locking support bar 4 cannot rotate. The locking support bar 4 is also connected to the rotating drive rod 2 through the receiving rod 25. Therefore, when the locking support bar 4 cannot rotate under the restriction of the anti-rotation channel 55, the rotating drive rod 2 can be locked by the locking support bar 4.

[0057] The movable rod 44 is symmetrically welded and fixed with linkage frames 45 at both ends. Locking blocks 46 are welded and fixed on the linkage frames 45. In addition, two first springs 48 on the movable rod 44 are respectively located on both sides of the locking support bar 4, and the two ends of the first springs 48 are welded and fixed on the linkage frame 45 and the locking support bar 4, respectively. This is used to ensure the stability of the position of the movable rod 44 and can also be used for the movement of the movable rod 44.

[0058] When connecting the mesh bodies 1 or stabilizing the splicing strips 3 in the mounting cavity 13 to prevent them from protruding from the outside of the mesh support column 11, the locking support strip 4 needs to be locked. This requires inserting a locking block 46 on a linkage frame 45 into the corresponding insertion channel 281. The locking block 46 contacts the inner wall of the insertion channel 281. Specifically, a third threaded hole 47 is provided on the locking block 46. When the locking block 46 is inserted into the insertion channel 281, the third threaded hole 47 aligns with the second threaded hole 282. Rotating the threaded rod 29 engages with the third threaded hole 47 on the locking block 46, thus enabling... The threaded rod 29 causes the locking block 46 to be stably inserted into the insertion channel 281. The locking support bar 4 is locked by the cooperation between the insertion channel 281 and the locking block 46. At this time, the locking support bar 4 is inserted into the anti-rotation channel 55. Since the locking block 46 is inserted into the insertion channel 281, the locking support bar 4 cannot move along the support rod 25. This can firmly fix the locking support bar 4 in the anti-rotation channel 55. In the connected state of the net body 1, the stability of the connection between the net body 1 can be guaranteed. When no part of the splicing strip 3 protrudes from the outside of the net support column 11, the stability of the splicing strip 3 can be guaranteed.

[0059] like Figure 1 , Figure 2 , Figure 13 and Figure 14As shown, the connecting locking assembly includes: a mating fixing strip 6 and an auxiliary splicing plate 7. The mating fixing strip 6 is inserted into the hollow support column 12 of the mesh. Specifically, a first connecting rod 62 is welded and fixed to one end of the mating fixing strip 6, and a second connecting rod 63 is welded and fixed to the other end of the mating fixing strip 6. The first connecting rod 62 is inserted into a connecting insertion hole 122 at the end away from the mating guide hole 123, and the second connecting rod 63 is inserted into another connecting insertion hole 122. A first support plate 64 is welded and fixed to the end of the first connecting rod 62 away from the mating fixing strip 6. The first support plate 64 is located on the outside of the hollow support column 12 of the mesh. A second support plate 66 is welded and fixed to the end of the second connecting rod 63 away from the mating fixing strip 6, and the second support plate 66 is also located on the outside of the hollow support column 12 of the mesh.

[0060] A second spring 65 is sleeved on both the first connecting rod 62 and the second connecting rod 63. The two ends of the second spring 65 sleeved on the first connecting rod 62 are respectively welded and fixed on the first support plate 64 and the column protrusion 121. The two ends of the second spring 65 sleeved on the second connecting rod 63 are respectively welded and fixed on the second support plate 66 and the other column protrusion 121.

[0061] On the other end of the hanging mesh support column 11 away from the limiting semi-ring 5, there are symmetrically arranged connecting holes 18 on the upper and lower sides. There are two auxiliary splicing plates 7, which are located on the outside of the hanging mesh hollow support column 12 and are movably connected with the matching fixing strip 6. Specifically, matching support strips 67 are symmetrically welded and fixed at the upper and lower ends of the second support plate 66. A connecting support rod 68 is hinged to the matching support rod 67. An auxiliary splicing plate 7 is hinged to the other end of the connecting support rod 68. A matching support rod 71 is welded and fixed to the auxiliary splicing plate 7. The matching support rod 71 is inserted into the matching guide hole 123. The matching support rod 71 and the matching guide hole 123 limit the auxiliary splicing plate 7. The matching support rod 71 can move along the matching guide hole 123.

[0062] When the mesh bodies 1 are spliced ​​together, the linkage frame 45 on one mesh body 1 drives the mating fixing strip 6 on the other mesh body 1 to move, thereby locking the mesh bodies 1 together. Specifically, the linkage frame 45 on one mesh body 1 is fitted onto the first support plate 64 on the other mesh body 1. When the linkage frame 45 moves, it drives the mating fixing strip 6 to move. A mating fixing block 61 is welded and fixed to the mating fixing strip 6. When the linkage frame 45 drives the mating fixing strip 6 to move, the mating fixing block 61 on the mating fixing strip 6 will be inserted into the fixing groove 32 on the splicing connecting strip 3. This fixes the splicing connecting strip 3 inserted into the hollow support column 12 of the mesh, preventing it from detaching from the hollow support column 12 of the mesh, thus ensuring the firmness of the connection between the mesh bodies 1.

[0063] When the fixing strip 6 moves, it drives the auxiliary splicing plate 7 to move as well, so that the auxiliary splicing plate 7 is fixedly connected to the net support column 11 on another net body 1. Specifically, the auxiliary splicing plate 7 is symmetrically and integrally formed with a mating wing plate 72, and auxiliary splicing columns 73 are welded and fixed on both the mating wing plate 72 and the auxiliary splicing plate 7. When the fixing strip 6 drives the auxiliary splicing plate 7 to move, the auxiliary splicing column 73 on the auxiliary splicing plate 7 will be inserted into the connection hole 18 on the other net body 1. In this way, with the cooperation of the auxiliary splicing column 73 and the connection hole 18, not only can the spliced ​​net body 1 be locked, but the connection between the two net bodies 1 can also be strengthened, which fully ensures the firmness and stability of the splicing.

[0064] When connecting the mesh bodies 1, the threaded rod 29 on one of the mesh bodies 1 used to lock the locking support bar 4 is rotated, causing the threaded rod 29 to separate from the third threaded hole 47. Then, under the action of the first spring 48, the locking support bar 4 is moved, causing the linkage frame 45 inserted in the insertion channel 281 to exit the insertion channel 281. This unlocks the locking support bar 4. Pulling the locking support bar 4 out of the anti-rotation channel 55 unlocks the rotation drive rod 2. Then, rotating the rotating support plate 23 drives the rotation drive rod 2 to rotate 180 degrees, which drives the eccentric connecting block 21 to rotate. Rotation causes the splicing link 3 to move under the action of the connecting ring 22, causing it to partially protrude from the outside of the hanging net support column 11. After the splicing link 3 moves into place, the locking support 4 is pushed to re-insert into the anti-rotation channel 55, thus locking the rotation drive rod 2. Then, the splicing link 3 can be inserted from the cavity of the hanging net hollow support column 12 on another hanging net body 1 into the hanging net hollow support column 12, so that the connecting support 125 on the hanging net hollow support column 12 is inserted into the connecting slot 31 on the splicing link 3, until the splicing link 3 is fully inserted into the hanging net hollow support column 12. During this process, as the hanging net body 1 moves, the linkage frame 45 on the moving hanging net body 1 will be sleeved on the first of the other hanging net body 1. On the first support plate 64, after the two hanging net bodies 1 are connected, pull the linkage frame 45 that is not fitted onto the first support plate 64 to move it away from the locking support strip 4. This will also drive the other linkage frame 45 to move synchronously. As the other linkage frame 45 moves, since it is fitted onto the first support plate 64, it will also drive the first support plate 64 to move, which in turn will drive the mating fixing strip 6 to move. As the mating fixing strip 6 moves, the mating fixing block 61 on the mating fixing strip 6 will be inserted into the fixing groove 32 on the splicing connecting strip 3, and the mating fixing block 61 will contact the inner wall of the fixing groove 32. In this way, with the mating fixing block 61 and the fixing groove 32 cooperating, the splicing connecting strip 3 can be moved. The fixing strip 3 is fixed in place, preventing it from moving out of the hollow support post 12 of the mesh, thus locking the connection between the two mesh bodies 1. Furthermore, as the fixing strip 6 moves, the connecting support rod 68 moves the auxiliary splicing plate 7. This movement causes the auxiliary splicing plate 7 and the auxiliary splicing post 73 on the mating wing plate 72 to insert into the connecting hole 18 on the other mesh body 1. This cooperation between the auxiliary splicing post 73 and the connecting hole 18 not only further locks the connection between the two mesh bodies 1 but also strengthens it, ensuring the connection strength between the two mesh bodies 1.As the linkage frame 45, which is not fitted onto the first support plate 64, moves, the locking block 46 on the linkage frame 45 will insert into the corresponding insertion channel 281. Then, rotating the threaded rod 29 will cause the threaded rod 29 to be threaded into the third threaded hole 47, thus locking the locking support bar 4 and making it stably inserted into the anti-rotation channel 55, completing the connection between the two netting bodies 1. The operation is simple, convenient, and quick. When it is necessary to disassemble the netting bodies 1, the locking support bar 4 is also unlocked. As the movable support rod 44 moves, the second spring 65 will cause the fixing bar 6 to reset, thus unlocking the two netting bodies 1. Then, the two can be disassembled. Rotating the rotation drive rod 2 again will reset the splicing connecting bar 3 and put it away again. As the splicing connecting bar 3 is put away, the netting support column 11 will return to its cylindrical shape, making it easy for personnel to grip.
