[0006] Preferably, the swing mechanism includes a worm fixedly connected to the end of the double-shaft motor away from the drive shaft. A worm gear is meshed with the outer surface of the worm. Through the swing mechanism, the swing frame can swing back and forth along the frame shaft, so that the warning light rotates while swinging by a certain amplitude under the action of the double-shaft motor.

[0007] Preferably, a first connecting shaft is fixedly sleeved on the inner surface of the worm gear. Drive wheels are fixedly connected to both ends of the first connecting shaft. A gear rack is rotatably connected to the outer surface of the first connecting shaft.

[0008] Preferably, a second connecting shaft is rotatably connected to the inner surface of the gear rack. A transmission wheel is fixedly sleeved on the outer surface of the second connecting shaft. The outer surface of the transmission wheel is meshed with the outer surface of the drive wheel.

[0009] Preferably, one end of the second coupling shaft is fixedly connected with an eccentric wheel, and an upper arm shaft is fixedly penetrated through the inner side of the fixing frame. The eccentric design of the eccentric wheel enables the swing arm to swing.

[0010] Preferably, a swing arm is rotatably connected to the outer surface of the upper arm shaft. The bottom of the swing arm is fixedly connected with a lower arm shaft, and the outer surface of the lower arm shaft is rotatably connected with the inner surface of the eccentric wheel.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. For this portable warning frame, through the swing mechanism, the position and angle of the warning light can be dynamically adjusted according to environmental changes, enabling the warning light to swing to a certain extent while rotating, which can significantly increase the coverage area of the warning light, ensuring that obvious warning signals can be received in a wider area, so as to adapt to different application scenarios and requirements.

DETAILED DESCRIPTION OF THE INVENTION

[0020] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0021] Please refer to Figures 1-5 , a portable warning stand, including a tripod 1, a fixed box 2 is fixedly installed at the top of the tripod 1, a fixed frame 3 is fixedly connected inside the fixed box 2, a frame shaft 4 is fixedly connected inside the fixed frame 3, a swing frame 5 is rotatably connected to the outer surface of the frame shaft 4, a dual-axis motor 6 is arranged inside the swing frame 5, for the dual-axis motor 6, one output end of the dual-axis motor 6 is fixedly connected to a drive shaft 7, a warning light 8 is fixedly installed at the end of the drive shaft 7 away from the dual-axis motor 6, a swing mechanism is arranged inside the fixed frame 3, and a waterproof plug 20 is movably installed on the top of the fixed box 2.

[0022] Through the above technical solution, the portable warning stand is composed of a tripod 1 with a retractable bottom, a fixed box 2 (including internal components), and a warning light 8 above. The overall design is compact and easy to carry and deploy. The bright red and blue flashing warning light of the warning light 8 and the eye-catching logo can quickly attract people's attention in a complex environment.

[0023] Specifically, the swing mechanism includes a worm gear 9 fixedly connected to the end of the dual-axis motor 6 away from the drive shaft 7, and a worm wheel 10 is meshed with the outer surface of the worm gear 9.

[0024] Through the above technical solution, when one output end of the dual-axis motor 6 drives the worm gear 9 to rotate, the worm gear 9 can drive the worm wheel 10 engaged therewith to rotate self.

[0025] Specifically, a first coupling shaft 11 is fixedly sleeved on the inner surface of the worm wheel 10, and drive wheels 12 are fixedly connected to both ends of the first coupling shaft 11. The outer surface of the first coupling shaft 11 is rotatably connected to a gear rack 13.

[0026] Through the above technical solution, drive wheels 12 are arranged at both ends of the first coupling shaft 11. That is, when the first coupling shaft 11 rotates self synchronously with the worm wheel 10, the two groups of drive wheels 12 will also rotate self synchronously.

[0027] Specifically, a second coupling shaft 14 is rotatably connected to the inner surface of the gear rack 13, a transmission wheel 15 is fixedly sleeved on the outer surface of the second coupling shaft 14, and the outer surface of the transmission wheel 15 is meshed with the outer surface of the drive wheel 12.

[0028] Through the above technical solution, during the rotation of the driving wheel 12, it will drive the transmission wheel 15 to rotate, thereby driving the second coupling shaft 14 to rotate on its own. During this period, the eccentric wheel 16 will rotate with the self-rotation of the second coupling shaft 14.

[0029] Specifically, one end of the second coupling shaft 14 is fixedly connected with an eccentric wheel 16, and the upper arm shaft 17 is fixedly penetrated through the inner side of the fixing frame 3.

[0030] Through the above technical solution, during the rotation of the eccentric wheel 16, it will drive the swing arm 18 through the lower arm shaft 19, so that the swing arm 18 swings along the upper arm shaft 17 by a certain amplitude.

[0031] Specifically, the outer surface of the upper arm shaft 17 is rotatably connected with a swing arm 18. The bottom of the swing arm 18 is fixedly connected with a lower arm shaft 19, and the outer surface of the lower arm shaft 19 is rotatably connected with the inner surface of the eccentric wheel 16.

[0032] Through the above technical solution, during the movement of the swing arm 18, it will pull the gear rack 13 to swing, and push against the worm 9 through the first coupling shaft 11 and the worm gear 10, so that the swing frame 5 rotates along the frame shaft 4 to a certain extent. And under the gravity of the swing frame 5 and the dual-axis motor 6 inside it, it will return to its original position, thus achieving the effect of swinging back and forth to a certain extent.

[0033] Working principle: When carrying this warning frame, only need to lift the tripod 1. The warning light 8 can emit bright and flashing red and blue warning lights and eye-catching signs. Under normal conditions, the warning light 8 is in the Figure 1 vertical placement state as shown. At this time, the waterproof plug 20 is inserted into the opening at the top of the fixed box 2 to achieve the waterproof effect. When it is necessary to adapt to the dynamic changing environment and increase the coverage range of the warning light, at this time, the inserted waterproof plug 20 needs to be taken out (here is to allow the drive shaft 7 to deflect smoothly), and the dual-axis motor 6 is turned on to drive the drive shaft 7 to rotate. During this period, the drive shaft 7 will drive the warning light 8 to rotate on its own. At the same time, the other end of the dual-axis motor 6 will drive the worm 9 to drive the worm gear 10 to rotate on its own. During this process, the first coupling shaft 11 will rotate synchronously, and the driving wheels 12 at both ends of the first coupling shaft 11 will drive the corresponding transmission wheels 15, so that the transmission wheel 15 and the second coupling shaft 14 rotate on their own. Finally, during the process that the second coupling shaft 14 drives the eccentric wheel 16 to rotate, it will drive the swing arm 18 to deflect through the lower arm shaft 19, so that it swings along the upper arm shaft 17 by a certain amplitude. And during the swinging process of the swing arm 18, it will push and pull the gear rack 13, so that it cooperates with the worm gear 10 to push the worm 9 forward, so that the swing frame 5 rotates along the frame shaft 4, that is, the warning light 8 at the top of the drive shaft 7 will swing by a certain amplitude, increasing the coverage range of the light and warning signals, so as to achieve the best warning effect in a complex environment to cope with emergencies or urgent situations.

[0034] Although embodiments of the present application have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present application.
