[0002] Braided springs are a special type of spring made of metal wires woven into a strip structure. They are also called braided springs, mesh springs, or flat springs. Unlike common spiral compression / tension / torsion springs, braided springs are made of multiple thin metal wires that are woven together at specific angles like a braided strip. The final result is a flat, mesh structure, similar to a very dense metal mesh, and the whole thing presents a flexible plane.

[0003] Regarding the above and existing related technologies, the inventor believes that the following defects often exist: When existing braided springs are assembled with other components, they are usually connected by welding, which requires operators to have corresponding professional skills to operate. This not only results in low overall efficiency but also introduces errors, thereby affecting the overall quality of the product. Summary of the Invention

[0023] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0024] Reference Figures 1-5 As shown, this utility model provides a technical solution: a quick-assembly braided spring, including a braided spring body 1: both ends of the braided spring body 1 are folded to form a long strip 101 and a short strip 102 respectively, the short strip 102 is located on top of the long strip 101, and a connector 2 is installed inside the folded ends of the braided spring body 1. A lower pressure plate 3 is provided at the bottom of the long strip 101, and an upper pressure plate 4 is provided at the top of the short strip 102. One end of the lower pressure plate 3 is rotatably connected to one end of the upper pressure plate 4 through a pivot. A housing 5 is fixed at the top end of the lower pressure plate 3 away from the pivot, and a fixing block 7 is fixed at the bottom end of the upper pressure plate 4 away from the pivot. An opening 6 is provided on the top of the housing 5 to cooperate with the fixing block 7, and fixing grooves 8 are provided on both sides of the fixing block 7.

[0025] The housing 5 contains a fixing assembly for fixing the fixing block 7. The fixing assembly includes two inserts 9 that mate with the fixing groove 8. Both inserts 9 are located inside the housing 5. A transmission rod 10 is fixed to the bottom of each insert 9. A movable block 12 is located at the bottom of the housing 5. A first groove 11 is formed at the bottom of the transmission rod 10. Second grooves 13 are formed on both sides of the movable block 12. A connecting rod 14 is rotatably connected to the first groove 11 via a rotating shaft. The other end of the connecting rod 14 is rotatably connected to the second groove 13 via a rotating shaft. A control rod 15 is fixed to one side of the movable block 12. A through groove 16 is formed on the side of the housing 5 where the control rod 15 is located, and it is slidably connected to the control rod 15. The control rod 15 is located away from the movable block 12. One end of the movable block 12 is parallel to the outer surface of the housing 5. The end of the control rod 15 away from the movable block 12 has a control hole 24. The surface of the transmission rod 10 has a first through hole 17. The first slide rod 18 is slidably connected inside the first through hole 17. Both ends of the first slide rod 18 are fixed to the two ends of the inner wall of the housing 5. By folding both ends of the braided spring body 1 to form a long belt 101 and a short belt 102, the short belt 102 is stacked on top of the long belt 101. The connecting piece 2 is pre-installed inside the fold. Then, the lower pressure plate 3 is placed at the bottom of the long belt 101, and the upper pressure plate 4 is rotated to the top of the short belt 102 through the rotating shaft. At this time, the lower pressure plate 3 and the upper pressure plate 4 are both located at the stacking of the long belt 101 and the short belt 102. When the lower pressure plate 3 and the upper pressure plate 4 are parallel to each other through the rotating shaft... The fixed block 7 enters the interior of the housing 5 through the opening 6 at the top of the housing 5. Before the fixed block 7 enters the interior of the housing 5, the control rod 15 is moved upward through the control hole 24, thereby driving the movable block 12 upward. This causes the connecting rod 14 to push the transmission rod 10 in a direction away from each other. During the movement of the transmission rod 10, the sliding connection between the first through hole 17 and the first slide rod 18 guides and limits the movement of the transmission rod 10, preventing the transmission rod 10 from deviating. When the movable block 12 moves upward to a state parallel to the connecting rod 14, the position of the insert block 9 will not interfere with the movement of the fixed block 7. At this time, the fixed block 7 can easily enter the interior of the housing 5. Then, by reversing the operation, the control rod 15 drives the transmission rod 10 to move upward. The movable block 12 moves downward, causing the transmission rod 10 to move towards the fixed block 7 via the connecting rod 14, so that the insert block 9 is inserted into the fixed groove 8. When the bottom of the movable block 12 moves to contact the bottom of the housing 5, the fixed block 7 is fixed. By mechanically folding the braided spring body 1 to form a long belt 101 and a short belt 102 and pre-installing the connector 2, the traditional welding step is eliminated, significantly reducing the skill requirements for operators. After the fixed block 7 is inserted into the housing 5, the single-bar linkage mechanism consisting of the control rod 15, the movable block 12, the connecting rod 14, the transmission rod 10, the first through hole 17, and the first slide rod 18 can simultaneously drive the insert blocks 9 on both sides to be precisely inserted into the fixed groove 8 by operating only one control rod 15.Achieving reliable mechanical locking, this design not only simplifies the operation process but also ensures reliable and consistent locking through precise mechanical fitting and the interaction between the first through hole 17 and the first slide rod 18, completely avoiding errors that may arise from manual welding.

[0026] Reference Figure 4 and Figure 5 As shown in this embodiment: both ends of the first slide rod 18 are fitted with a first spring 19. One end of the first spring 19 is fixed to the transmission rod 10, and the other end of the first spring 19 is fixed to the inner wall of the housing 5. By setting the first spring 19, the position of the transmission rod 10 can be limited, so as to prevent the insert block 9 from easily disengaging from the inside of the fixing groove 8 when it is inserted into the fixing groove 8.

[0027] Reference Figure 5 As shown in this embodiment: the top of the movable block 12 is provided with a second through hole 20, and the bottom of the housing 5 is fixed with a second slide rod 21 that is slidably connected to the second through hole 20. The top of the second slide rod 21 is fixed with a limit block 22. The sliding connection between the second through hole 20 and the second slide rod 21 plays a role in guiding the movement of the movable block 12 and preventing the movable block 12 from deviating when it moves.

[0028] Reference Figure 5 As shown in this embodiment: a second spring 23 is sleeved on the surface of the second slide rod 21. The top end of the second spring 23 is fixed to the bottom of the limiting block 22, and the bottom end of the second spring 23 is fixed to the top of the movable block 12. The second spring 23 forms a downward pressure on the movable block 12. By cooperating with the first spring 19, it ensures the position of the transmission rod 10 is limited, and at the same time shares the reverse force generated when the transmission rod 10 moves unexpectedly, thereby slowing down the time of mechanical fatigue.

[0029] Reference Figure 2 As shown in this embodiment: three locking strips 25 are fixed on the opposing surfaces of the lower pressure plate 3 and the upper pressure plate 4. The three locking strips 25 are evenly distributed at the same interval in the order of left, center and right. The evenly distributed locking strips 25 provide stable support and prevent the spring from horizontally displacing.

[0030] Reference Figure 2 As shown in this embodiment: twelve protrusions 26 are fixed on the opposing surfaces of the lower pressure plate 3 and the upper pressure plate 4. The protrusions 26 are conical structures with their tips facing the braided spring body 1. The twelve protrusions 26 are evenly divided into four groups of three. The four groups of protrusions 26 are evenly distributed on both sides of the central retaining strip 25. The tips of the protrusions 26 penetrate the spring surface to form a physical engagement, preventing slippage after assembly.

[0031] Working principle: By folding both ends of the braided spring body 1 to form a long belt 101 and a short belt 102, the short belt 102 is stacked on top of the long belt 101. A connector 2 is pre-installed inside the fold. Then, the lower pressure plate 3 is placed at the bottom of the long belt 101, while the upper pressure plate 4 rotates to the top of the short belt 102 via a pivot. At this point, both the lower pressure plate 3 and the upper pressure plate 4 are located at the stacking point of the long belt 101 and the short belt 102. When the lower pressure plate 3 and the upper pressure plate 4 are parallel to each other via the pivot, they compress the long belt 101 and the short belt 102. Stable support is provided by the evenly distributed retaining strips 25, preventing horizontal displacement of the spring. The tip of block 26 penetrates the spring surface to form a physical engagement, preventing slippage after assembly. When the lower pressure plate 3 and the upper pressure plate 4 are parallel to each other, the fixing block 7 will enter the interior of the housing 5 through the opening 6 at the top of the housing 5. Before the fixing block 7 enters the interior of the housing 5, the control rod 15 is moved upward through the control hole 24, thereby driving the movable block 12 to move upward, causing the connecting rod 14 to push the transmission rod 10 to move in a direction away from each other. During the movement of the movable block 12, the sliding connection between the second through hole 20 and the second slide rod 21 guides the movement of the movable block 12, preventing the movable block from slipping. If the movable block 12 deviates during movement, the sliding connection between the first through hole 17 and the first slide rod 18 during the movement of the transmission rod 10 guides and limits the movement of the transmission rod 10, preventing it from deviating. When the movable block 12 moves upward to a state parallel to the connecting rod 14, the position of the insert block 9 will not interfere with the movement of the fixed block 7. At this time, the fixed block 7 can easily enter the interior of the housing 5. Then, by reversing the operation, the control rod 15 drives the movable block 12 downward, causing the movable block 12 to drive the transmission rod 10 towards the fixed block 7 via the connecting rod 14. The insert 9 is inserted into the fixed groove 8. When the bottom of the movable block 12 moves to contact the bottom of the inside of the housing 5, the fixed block 7 is fixed. The first spring 19 limits the position of the transmission rod 10, preventing the insert 9 from easily disengaging from the inside of the fixed groove 8 when it is inserted. The second spring 23 applies downward pressure to the movable block 12. In conjunction with the first spring 19, the position of the transmission rod 10 is limited while sharing the reverse force generated when the transmission rod 10 moves unexpectedly, thereby reducing the time for mechanical fatigue.

[0032] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
