DETAILED DESCRIPTION

[0025] In order to further understand the features, technical means and specific purposes and functions achieved by the utility model, the utility model will be described in further detail below in combination with the drawings and specific embodiments

[0026] Referring to Figures 1-6 As shown in the figure, a tent framework for improving tent stability comprises a plurality of hollow support rods 1, the top end of the support rod 1 is fixed with a first hinge seat 11, the outside of the support rod 1 is provided with a second hinge seat 15 capable of sliding along the central axis direction, the two sides of the support rod 1 close to the top end are provided with a let-in slot 12, the two sides of the bottom of the support rod 1 close to the let-in slot 12 are symmetrically provided with two mounting holes 13, and the inside of the support rod 1 is provided with a limiting mechanism 2 capable of limiting the second hinge seat 15;

[0027] The limiting mechanism 2 comprises two groups of mounting shafts 21, the two ends of the mounting shaft 21 are respectively mounted in the inside of the mounting hole 13, the two groups of mounting shafts 21 are hingedly provided with a limiting block 22, and the top end of the limiting block 22 is provided with a supporting part 222 capable of penetrating the let-in slot 12 and lifting the bottom of the second hinge seat 15;

[0028] The opposite faces of the two groups of limiting blocks 22 close to the top are provided with a mounting slot 223, and a return spring 23 capable of rotating the two groups of limiting blocks 22 along the central axis of the mounting shaft 21 is horizontally arranged between the two groups of limiting blocks 22, and the two ends of the return spring 23 are respectively mounted in the inside of the mounting slot 223.

[0029] When the second hinge seat 15 goes up along the central axis of the support rod 1, the top end of the second hinge seat 15 will extrude the slope bottom provided by the supporting part 222. This extrusion causes the bottom of the supporting part 222 to rotate along the central axis of the mounting shaft 21. With the rotation, the top ends of the two groups of supporting parts 222 gradually approach until one end of the supporting part 222 completely enters the inside of the let-in slot 12. It is ensured that the second hinge seat 15 can smoothly go up along the central axis of the support rod 1. At the same time, the return spring 23 mounted in the inside of the mounting slot 223 starts to accumulate potential energy under the extrusion of the supporting part 222. When the second hinge seat 15 passes through the top end of the supporting part 222, the extrusion force borne by the return spring 23 disappears. At this time, the return spring 23 releases the accumulated potential energy, and the return spring 23 pushes the supporting part 222 to extend out of the inside of the let-in slot 12, thereby supporting the bottom of the second hinge seat 15. If the down operation of the second hinge seat 15 is needed, the two groups of supporting parts 222 are pressed at the same time, so that the supporting part 222 reenters the inside of the let-in slot 12, so that the second hinge seat 15 can smoothly move downward along the central axis of the first hinge seat 11.

[0030] Referring to Figure 1 and Figure 2As shown, the folding mechanism 3 is arranged between the two groups of support rods 1, and the folding mechanism 3 comprises two groups of third hinge seats 31. The first folding frame 32 is hingedly arranged on the two sides of the third hinge seat 31. The bottom and the top of one end of the first folding frame 32 are hingedly connected with the third hinge seat 31 respectively. The top of the other end of the first folding frame 32 away from the third hinge seat 31 is hingedly arranged with the first hinge seat 11. The bottom of the other end of the first folding frame 32 away from the third hinge seat 31 is hingedly arranged with the second hinge seat 15.

[0031] When the second hinge seat 15 moves upward along the central axis of the support rod 1, the second hinge seat 15 will synchronously drive the bottom of one end of the first folding frame 32 to move upward. During this process, the two groups of third hinge seats 31 away from the second hinge seat 15 will move closer to each other, thereby realizing the unfolding of the tent framework. Conversely, when the second hinge seat 15 moves downward along the central axis of the support rod 1, the second hinge seat 15 will synchronously drive the bottom of one end of the first folding frame 32 to move downward. At this time, the two groups of third hinge seats 31 away from the second hinge seat 15 will move away from each other, thereby realizing the folding of the tent framework.

[0032] Referring to Figure 1 and Figure 2 As shown, the third hinge seat 31 is hingedly arranged with the second folding frame 4 which can be unfolded or folded. The second folding frame 4 is longitudinally arranged with the top rod 5 for lifting the tent at one end away from the third hinge seat 31. The second folding frame 4 is hingedly arranged with the top rod 5 at one end away from the third hinge seat 31.

[0033] When the two groups of third hinge seats 31 move closer to each other, the two groups of third hinge seats 31 will synchronously drive the second folding frame 4 arranged on one side to unfold. During this unfolding process, the movement of the second folding frame 4 will drive the top rod 5 to gradually move away from the corresponding third hinge seat 31, thereby completing the expansion of part of the tent framework. Conversely, when the two groups of third hinge seats 31 move away from each other, the two groups of third hinge seats 31 will synchronously drive the second folding frame 4 arranged on one side to fold. During the folding process, the movement of the second folding frame 4 will drive the top rod 5 to gradually move closer to the corresponding third hinge seat 31, thereby completing the folding of part of the tent framework.

[0034] Referring to Figure 1 and Figure 2 As shown, the bottom end of the top rod 5 is fixed with the fourth hinge seat 51, and the bottom of one end of the second folding frame 4 away from the third hinge seat 31 is hingedly arranged with the fourth hinge seat 51.

[0035] In the process of unfolding or folding the second folding frame 4, the bottom of the end of the second folding frame 4 away from the third hinge seat 31 drives the fourth hinge seat 51 to move longitudinally along the central axis of the top rod 5. Specifically, when the fourth hinge seat 51 moves downward along the central axis of the top rod 5, the protruding part of the top rod 5 will rise relative to the fourth hinge seat 51. Conversely, when the fourth hinge seat 51 moves upward along the central axis of the top rod 5, the protruding part of the top rod 5 will descend relative to the fourth hinge seat 51.

[0036] Referring to Figure 1 and Figure 2 , the outer part of the top rod 5 is provided with a fifth hinge seat 52 that can slide along the central axis thereof, and the top of the end of the second folding frame 4 away from the third hinge seat 31 can be hingedly arranged with the fifth hinge seat 52.

[0037] In the process of unfolding the second folding frame 4, the top of the end of the second folding frame 4 away from the third hinge seat 31 drives the fifth hinge seat 52 to move downward along the central axis of the top rod 5. As the second folding frame 4 is gradually unfolded, when the second folding frame 4 is completely unfolded, the fourth hinge seat 51 at the end away from the third hinge seat 31 will move along the top rod 5 to a position closer to the center line thereof and close to the central position of the top rod 5. At this time, the second folding frame 4 forms effective support to the top rod 5 through the fourth hinge seat 51, ensuring that the top rod 5 can maintain a vertical state. Stable connection and support between the second folding frame 4 and the top rod 5 is achieved.

[0038] Referring to Figure 1 , the top end of the top rod 5 is provided with a top block 53 to avoid penetrating the tent top.

[0039] In order to improve the service life of the tent, the top block 53 is arranged at the top end of the top rod 5. When the top rod 5 is raised, the top block 53 arranged at the top end of the top rod 5 contacts and exerts a supporting force on the tent, so that the top rod 5 supports the tent through the top block 53. Direct contact between the top rod 5 and the tent material is avoided, effectively preventing the tent top from being penetrated by the top rod 5. Not only does this enhance the stability of the tent structure, but it also significantly improves the overall durability of the tent.

[0040] Referring to Figure 1 , Figure 2 and Figure 4 , the support rod 1 is provided with a clamping groove 14 near the bottom end; the inner part of the bottom end of the support rod 1 is provided with an extension rod 6 that can longitudinally extend and retract, and the inner part of the extension rod 6 near the top end is provided with an elastic clamping block 61 that can rebound and be clamped in the clamping groove 14.

[0041] In the process of adjusting the height of the tent framework, the extension rod 6 is pulled out from the inside of the support rod 1, and at the same time, the elastic clamping block 61 arranged inside the extension rod 6 gradually approaches the clamping groove 14. With the continuous pulling out of the extension rod 6, the elastic clamping block 61 is finally clamped in the inside of the clamping groove 14. It is ensured that the extension rod 6 can be stably fixed in the inside of the support rod 1 through the cooperation of the elastic clamping block 61 and the clamping groove 14.

[0042] Referring to Figure 1 As shown, the bottom end of the extension rod 6 is fixed with a support foot 62 capable of improving the stability of the tent support.

[0043] In order to improve the stability of the tent, the support foot 62 is additionally arranged at the bottom end of the extension rod 6. When the extension rod 6 supports the tent, the support foot 62 at the bottom of the extension rod 6 can effectively increase the contact area with the ground. The support foot 62 can disperse the pressure of the tent framework on the ground, thereby ensuring the stability of the tent structure and improving the overall stability of the tent. The situation that the tent framework sinks into the ground due to uneven force in the use process is effectively avoided.

[0044] When the utility model works, the unfolding and folding of the tent framework is mainly realized by the up-down movement of the second hinge seat 15 along the central axis of the support rod 1. When the second hinge seat 15 goes up, the top end of the second hinge seat 15 will press the inclined surface arranged at the bottom of the support part 222, causing the support part 222 to rotate along the central axis of the mounting shaft 21, and the top ends of the two groups of support parts 222 gradually approach and enter the inside of the giving-up slot 12, thereby providing space for the upward movement of the second hinge seat 15. At the same time, the reset spring 23 is pressed and accumulates potential energy. When the bottom end of the second hinge seat 15 is higher than the support part 222, the reset spring 23 releases the potential energy and pushes the support part 222 to reset, thereby supporting the second hinge seat 15. The up-down movement of the second hinge seat 15 also synchronously drives the bottom of one end of the first folding frame 32 to rise, and then drives the second folding frame 4 to unfold or fold through the third hinge seat 31. In this process, the fourth hinge seat 51 away from one end of the third hinge seat 31 of the second folding frame 4 will move longitudinally along the central axis of the top rod 5, thereby changing the height of the top rod 5. At the same time, the fifth hinge seat 52 will also move along the central axis of the top rod 5. When the second folding frame 4 is completely unfolded, the fourth hinge seat 51 effectively supports the top rod 5, thereby ensuring the stability of the tent structure. In addition, in order to improve the service life and stability of the tent, the top block 53 is arranged at the top end of the top rod 5, thereby avoiding the direct contact of the top rod 5 with the tent material and preventing the top rod 5 from being penetrated. At the same time, the extension rod 6 can be pulled out from the inside of the support rod 1, and the extension rod 6 is fixed through the cooperation of the elastic clamping block 61 and the clamping groove 14, thereby adjusting the height of the tent framework. The support foot 62 at the bottom end of the extension rod 6 increases the contact area with the ground, disperses the pressure, and ensures the stability of the tent structure.

It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
