[0013] Further, in the present application, the outside of the first connecting rod is provided with a limiting ring, and the limiting ring is located above the guide block, so that the guide cylinder is directed towards the limiting ring.

[0014] Further, in the present application, a plurality of setting clamping holes are provided on the top of the bottom plate, one end of the support rod is provided with a connecting column, the outside of the connecting column is provided with a fixed clamping sleeve, the fixed clamping sleeve has elasticity, the fixed clamping sleeve is slightly larger than the setting clamping hole, the connecting column is inserted into the adjacent setting clamping hole, and the fixed clamping sleeve is clamped with the setting clamping hole.

[0015] Further, in the application, the other end of the supporting rod is provided with a mounting column, the other end of the second connecting rod is provided with a mounting groove, and the mounting column is screwed with the mounting groove.

[0031] In the description of the present application, it should be noted that, unless otherwise specifically defined and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected or can communicate with each other; it can be directly connected, or indirectly connected through an intermediate medium; it can be the communication or interaction relationship between two elements.

[0032] REFERENCE Figures 1-6In some embodiments, a fixing structure of an arc-shaped canopy includes a canopy foot 1, a bottom plate 2 provided at the bottom of the canopy foot 1, a plurality of ground peg fixing holes 3 provided in the inside of the bottom plate 2, a plurality of blocking rings 4 provided at the top of the bottom plate 2 and corresponding to the plurality of ground peg fixing holes 3, a plurality of first connecting rods 16 provided at the bottom of the blocking rings 4, a plurality of buffer springs 20 provided at one end of the first connecting rods 16, a plurality of second connecting rods 12 provided at one end of the buffer springs 20, a plurality of guide cylinders 15 provided at the outside of the second connecting rods 12, a plurality of movable cavities 17 provided at the top of the guide cylinders 15, the buffer springs 20 and the first connecting rods 16 being located in the movable cavities 17, the first connecting rods 16 being in sliding fit with the movable cavities 17, and a plurality of support rods 9 provided at the bottom of the second connecting rods 12 and connected with the bottom plate 2.

[0033] Through the above technical solution, when the head of the ground peg hits the blocking ring 4, the impact force is transmitted to the buffer spring 20 through the first connecting rod 16. The impact force causes the buffer spring 20 to compress. The elastic force of the spring increases with the increase of the compression amount until the impact force reaches a balance, that is, the peak value of the impact force is reduced. The impact force after buffering is now a smaller and more controllable force. When the force after buffering is transmitted to the support rod 9 through the second connecting rod 12, the strength of the force has been reduced, so the support rod 9 no longer needs to bear the original strong impact, which means that the impact force of the support rod 9 on the bottom plate 2 is reduced, thereby effectively reducing the risk of damage of the support rod 9 to the bottom plate 2 and prolonging the service life of the bottom plate 2.

[0034] It should be noted that, in order to avoid the buffer spring 20 from being twisted when it is compressed, the buffer spring 20 will drive the first connecting rod 16 to slide fit with the movable cavity 17 when it is compressed, thereby limiting the transverse position of the buffer spring 20.

[0035] In addition, the total length of the blocking ring 4, the first connecting rod 16, the guide cylinder 15, the second connecting rod 12 and the support rod 9 needs to be slightly longer than the insertable depth. This is because the compression of the buffer spring 20 will cause the blocking ring 4 to move downward. If the total length of the blocking ring 4, the first connecting rod 16, the guide cylinder 15, the second connecting rod 12 and the support rod 9 is equal to or less than the insertable depth of the ground peg, the downward movement of the blocking ring 4 may cause the ground peg to continue to penetrate, thereby losing the limiting effect. Therefore, the total length of the blocking ring 4, the first connecting rod 16, the guide cylinder 15, the second connecting rod 12 and the support rod 9 is controlled to be slightly longer than the insertable depth, so that even if the blocking ring 4 moves downward, it can still effectively prevent the ground peg from being excessively inserted.

[0036] Reference Figures 5-6 In some embodiments, the inside of the movable cavity 17 is provided with a plurality of guide sliding grooves 23, the outside of the first connecting rod 16 is provided with a plurality of guide sliding blocks 22, and the plurality of guide sliding blocks 22 are respectively in sliding fit with the plurality of guide sliding grooves 23.

[0037] Through the technical scheme, the cooperation of the guide sliding block 22 and the guide sliding groove 23 reduces the shaking and instability of the first connecting rod 16 during movement, thereby improving the stability of the entire device.

[0038] With reference to Figures 5-6 In some specific embodiments, one end of the second connecting rod 12 is provided with a first accommodating groove 18, the first accommodating groove 18 is communicated with the movable cavity 17, one end of the buffer spring 20 is inserted into the first accommodating groove 18, one end of the first connecting rod 16 is provided with a second accommodating groove 26, and the other end of the buffer spring 20 is inserted into the second accommodating groove 26.

[0039] Through the technical scheme, when the buffer spring 20 is compressed, the first accommodating groove 18 and the second accommodating groove 26 limit the two ends of the buffer spring 20, so that the buffer spring 20 can be kept in the correct position when subjected to external force, and the buffer spring 20 will not be displaced due to impact force, which helps to maintain the stability and reliability of the entire buffer system.

[0040] With reference to Figures 5-6 In some specific embodiments, the first accommodating groove 18 is provided with first clamping protrusions 19 on both sides of the inside, the first clamping protrusions 19 on both sides of the inside of the first accommodating groove 18 are externally clamped with one end of the buffer spring 20, the second accommodating groove 26 is provided with second clamping protrusions 24 on both sides of the inside, and the second clamping protrusions 24 on both sides of the inside of the second accommodating groove 26 are externally clamped with the other end of the buffer spring 20.

[0042] With reference to Figures 5-6 In some specific embodiments, the first connecting rod 16 is externally provided with a limiting ring 21, and the limiting ring 21 is located above the guide sliding block 22, so that the guide cylinder 15 faces the limiting ring 21.

[0043] Through the technical scheme, when the head of the ground nail moves under the impact force, the buffer spring 20 will be compressed, thereby driving the first connecting rod 16 to slide with the movable cavity 17 of the guide cylinder 15. Due to the blocking of the limiting ring 21, the first connecting rod 16 is prevented from being excessively inserted into the inside of the movable cavity 17, so that the first connecting rod 16 is not stuck in the movable cavity 17.

[0045] Through the above technical scheme, the support rod 9 and the bottom plate 2 are firmly connected through the clamping of the fixed card sleeve 11 and the setting card hole 25, the elastic fixed card sleeve 11 can provide sufficient clamping force, and the support rod 9 will not easily fall off when bearing external force; and the connection mechanism is simple and easy to operate, and only simple insertion and pulling out actions are needed when installing and dismounting the support rod 9, which greatly improves the installation efficiency.

[0047] Through the above technical scheme, when the mounting column 13 is screwed into the mounting groove 14, the spiral structure of the thread will generate friction between the two, thereby achieving firm connection, and when the insertion depth needs to be adjusted, the length of the support rod 9 can be replaced to adapt.

[0048] Referring to Figures 1-2 In some embodiments, the top of the bottom plate 2 is provided with a plurality of lifting columns 5, and the top of the lifting column 5 is provided with a lifting ring 6.

[0050] Referring to Figures 1-2 In some embodiments, the bottom of the tent leg 1 is provided with a bearing seat 7, the bearing seat 7 is connected with the bottom plate 2, one side of the bearing seat 7 is provided with a bearing placement cavity 8, and the bearing placement cavity 8 is used for placing bearing materials.
