[0021] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0022] refer to Figure 1-5 This embodiment provides a windproof advertising display bracket, including a main pole 1, a supporting leg 2 and a base 3.

[0023] Among them, a connecting plate 4 is provided under the main rod 1, and the connecting plate 4 is provided on the base 3 through a spring 5. The pitch of the spring 5 is equal to the wire diameter of the spring 5. Fixed blocks 51 are welded at both ends of the spring 5, and the fixed blocks 51 are connected to the base 3 and the mounting plate through bolts respectively. The above structure enables the bracket to have a certain buffering effect when it is subjected to lateral impact, reduces the shaking of the billboard caused by wind force, and at the same time prolongs the service life of the bracket.

[0024] The support legs 2 are provided with four, and the four support legs 2 are hingedly fixed to the base 3. The support legs 2 are provided with through holes 21 near the hinges, and the base 3 is provided with a plurality of mounting holes 31 that are rotationally aligned with the through holes 21. When the through holes 21 are aligned with any mounting holes 31, a pin or bolt is passed through the through holes 21. The structural setting of the support legs 2 and the base 3 realizes a stable connection between the support legs 2 and the base 3. At the same time, the height adjustment range of the bracket can be increased by adjusting the hinge angle between the support legs 2 and the base 3, thereby improving its scope of application.

[0025] The main pole 1 is provided with a fixing device for fixing the billboard, and the fixing device includes an upper fixing structure 61 and a lower fixing structure 62. The upper fixing structure 61 and the lower fixing structure 62 are symmetrically arranged, and both include a sleeve 601 sleeved on the main pole 1, and one end of the sleeve 601 is coaxially provided with a fixing cylinder 602, and the inner diameter of the sleeve 601 is larger than the inner diameter of the fixing cylinder 602, and a smooth transition cylinder 603 is formed between the sleeve 601 and the fixing cylinder 602, and the cylinder walls of the fixing cylinder 602 and the transition cylinder 603 are provided with at least two clearance grooves 604 along their axial direction, and a clamp is sleeved on the outer side of the fixing cylinder 602 605, the fixing sleeve is fixed on the main rod 1 by the clamp 605, so that the fixing sleeve 602 can be adjustably arranged on the main rod 1, the other end of the sleeve 601 is provided with a bearing, the bearing includes an inner ring 6061, an outer ring 6062 and a ball 6063, the inner ring 6061 is fixedly sleeved on the sleeve 601, the outer ring 6062 is provided with a fixing piece 607, the outer ring 6062 is also provided with a fixing ring 6081, and also includes a synchronization rod 6082, the synchronization rod 6082 is inserted into the two fixing rings 6081 to ensure that when the billboard is rotated under force, the two bearings will rotate synchronously to ensure the flatness of the billboard, especially the flatness of the flexible billboard, and ensure its display effect; the outer ring 6062 of the bearing of the upper fixing structure 61 or the lower fixing structure 62 is fixed with an auxiliary ring 6091, and the auxiliary ring 6091 is connected to the sleeve 601 through a spring 6092, that is, one end of the spring 6092 is fixedly connected to the inner wall of the auxiliary ring 6091 The other end is fixedly connected to the outer wall of the sleeve 601, and a protective cover 6093 for shielding the mainspring 6092 is provided between the auxiliary ring 6091 and the sleeve 601. The mainspring 6092 is made of a material with a small elastic modulus and a low yield strength. These materials recover their original shapes slowly after being subjected to force, thereby reducing the rebound speed and preventing the billboard from rotating too violently and injuring passers-by, or being subjected to strong winds again during rotation, causing the billboard to receive excessive relative impact and fall to the ground.

[0026] It should be noted that the inner diameter difference between the sleeve 601 and the fixed sleeve 602 and the provision of the transition sleeve 603 greatly reduce the possibility that the sleeve 601 will also shrink when the fixed sleeve 602 is tightened by the clamp 605, thereby ensuring the stability of the bearing.

[0027] In this embodiment, the fixing members 607 are used to fix the billboard. Two fixing members 607 are provided and are detachably connected to the billboard via bolts or latches.

[0028] In this embodiment, the main rod 1 is a telescopic rod, which makes the bracket more convenient to transport and store, and can be adjusted to a suitable height as needed during installation.

[0029] In this embodiment, the base 3 is provided with a counterweight 7 to increase the stability of the bracket and ensure that it will not easily fall over under the action of wind.

[0030] In this embodiment, the free end of the support leg 2 is provided with an anti-slip sleeve 22, which effectively prevents the support leg 2 from slipping on a smooth ground and ensures the safety of the overall structure.

[0031] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it will be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
