DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following further describes the present utility model in detail with reference to the drawings and specific embodiments.

[0026] Embodiment 1:

[0027] Figures 1-3An automatically spring - open multi - rod linkage component shown includes a fixed sleeve 1, an inner shaft 2, a spring 3, an upper cover 4, a tightening cover screw 5, and a rotating rod 6. The fixed sleeve 1 serves as the main body part of the component. The fixed sleeve 1 is used to support and fix the entire multi - rod linkage component. It has an inner shaft mounting hole 11 inside, which is used to install the inner shaft 2. The inner shaft mounting hole 11 is formed in the middle - lower part of the fixed sleeve 1. The fixed sleeve 1 forms a partition 12 to block the upper outlet of the inner shaft mounting hole 11.

[0028] The inner shaft 2 is axially movably arranged inside the inner shaft mounting hole 11. The inner shaft 2 has a spring mounting hole 21 inside, which is used to place the spring 3. There is a tooth row 22 on the outer wall of the inner shaft 2, and the tooth row 22 is used to mesh with the gear 61 on the rotating rod 6. Among them, the spring 3 is arranged inside the spring mounting hole 21 and at the same time abuts against the inner shaft mounting hole 11 at one end, and provides the power for automatic spring - opening through its elastic force.

[0029] The upper cover 4 is placed on the top of the fixed sleeve 1 and is thread - connected to the tightening cover screw 5. It is used to close the top of the component and maintain the stability of the component.

[0030] The tightening cover screw 5 sequentially passes through the inner shaft 2 and the spring 3 from bottom to top along the central axis of the fixed sleeve 1 and is thread - connected to the upper cover 4. The screw rod 51 of the tightening cover screw 5 passes through the bottom plate of the inner shaft 2 and abuts against the bottom plate of the inner shaft 2 through the bolt head 52. The screw rod 51 passes through the partition 12 and is thread - connected to the upper cover 4, which is used to fix and adjust the position of the upper cover 4.

[0031] The rotating rod 6 is hinged in the mounting position 14 on the side wall of the fixed sleeve 1 through a hinge shaft 62. The hinge shaft 62 is perpendicular to the central axis of the fixed sleeve 1. There is an opening reserved on the bottom plate of the fixed sleeve 1 at the mounting position 14, which can realize the radial flipping of the rotating rod 6 along the fixed sleeve 1. There are four rotating rods 6 and they are hinged on the fixed sleeve 1. Each rotating rod 6 has a gear 61 that meshes with the tooth row 22 of the inner shaft 2, which is used to transmit the elastic force of the spring 3 and achieve linkage.

[0032] When the component is assembled, the elastic force of the spring 3 will cause the inner shaft 2 to have an axial movement. The tooth row 22 on the inner shaft 2 meshes with the gear 61 on the rotating rod 6, thereby driving the rotating rod 6 to rotate. Since the rotating rod 6 is hinged on the fixed sleeve 1 and the rotating rod 6 is connected to the tent support, their rotation will cause the tent support to unfold, realizing the automatic spring - opening of the tent. The screw rod 51 of the tightening cover screw 5 passes through the bottom plate of the inner shaft 2 and abuts against the bottom plate of the inner shaft 2 through the bolt head 52, ensuring the stability and reliability of the component. The reason for the automatic spring - opening of the spring is that during the process of the rotating rod 6 retracting into the mounting position 14, the gear 61 moves upward. Through the meshing action with the tooth row 22, the inner shaft 2 moves upward. The upward movement of the inner shaft 2 will compress the spring 3. The reaction force of the spring is applied to the inner shaft 2, and the inner shaft 2 generates a downward moving force, causing the rotating rod 6 to automatically support and spring open.

[0033] It should be understood that in this embodiment, when storing, the automatic support and springing open of the rotating rod 6 can be prevented by adjusting the degree of the threaded connection between the upper cover 4 and the screw rod 51.

[0034] The advantages of the automatically spring-open multi-rod linkage assembly are as follows:

[0035] 1. Automatic setup: Through the force of the spring and the linkage mechanism, the tent can be quickly and automatically unfolded, eliminating the need for manual operation of each part, thus improving the setup efficiency and user experience.

[0036] 2. Improved stability: The design of the four-rod linkage assembly ensures the stability of the tent after unfolding, avoiding the problem of unstable structure caused by manual setup.

[0037] 3. Force saving: Users do not need to exert too much force to set up the tent, which is especially suitable for people with limited physical strength and endurance.

[0038] 4. Enhanced safety: The automatically spring-open design reduces the risks during setup and avoids the possible injuries that users may suffer during manual setup.

[0039] 5. Easy storage: The design of the assembly enables the tent to be quickly folded when not in use, facilitating storage and carrying.

[0040] 6. Versatility and adaptability: This automatically spring-open multi-rod linkage assembly can be applied to tents of different types and sizes and even other folding objects, showing wide applicability.

[0041] Embodiment 2:

[0042] Based on Embodiment 1, in order to make up for the limitation of preventing the automatic support and springing open of the rotating rod by adjusting the degree of the threaded connection between the upper cover 4 and the screw rod, an L-shaped limiting groove 13 is formed along the edge downward on the end wall of the fixed sleeve 1, and an L-shaped protrusion 41 is correspondingly arranged on the inner wall of the upper cover 4. Specifically, as Figure 5 shown, the L-shaped limiting groove 13 is composed of a vertical groove 13a and a horizontal groove 13b, and the L-shaped protrusion 41 is composed of a vertical block 41a and a horizontal block 41b. The horizontal width of the vertical groove 13a is greater than the horizontal width of the horizontal block 41b, and the longitudinal width of the horizontal groove 13b matches the longitudinal width of the horizontal block 41b.

[0043] When the user hopes to lock the upper cover 4 to prevent the rotating rod from automatically bouncing open, move the upper cover 4 up and down so that the horizontal block 41b of the L-shaped protrusion 41 enters the horizontal groove 13b, and at the same time the vertical block 41a enters the vertical groove 13a. Since the horizontal width of the vertical groove 13a is greater than the horizontal width of the horizontal block 41b, the horizontal block 41b can slide freely in the vertical groove 13a. The upper cover 4 can be rotated to move the horizontal block 41b to the horizontal groove 13b. When the horizontal block 41b is completely located in the horizontal groove 13b and the vertical block 41a is stuck at the bottom of the vertical groove 13a, the upper cover 4 is firmly locked on the fixed sleeve 1, preventing the movement of the rotating rod, thereby preventing the automatic unfolding of the tent. When the user needs to unlock the upper cover 4 so that the tent can be automatically unfolded, just rotate the upper cover 4 in the reverse direction to make the horizontal block 41b of the L-shaped protrusion 41 exit the horizontal groove 13b, and the vertical block 41a and the horizontal block 41b are lifted out of the vertical groove 13a together. Once the L-shaped protrusion 41 leaves the limit groove 13, the lock between the upper cover 4 and the fixed sleeve 1 is released, and the force of the spring can drive the rotating rod to automatically bounce open, realizing the rapid erection of the tent.

[0044] Through this design, Embodiment 2 provides an intuitive and easy-to-operate locking mechanism, which not only makes up for the limitations of thread connection adjustment, but also provides a more reliable locking method to ensure that the tent remains stable when needed and can be quickly unfolded when needed for erection.

[0045] The above embodiments are not limitations on the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present invention also fall within the protection scope of the present invention.
