[0004] Existing beam moving head lights are easily shaken by wind in an open-air outdoor environment, and then blown down, causing damage to the internal lamp structure. Utility Model Content

[0005] The purpose of this solution is to provide an anti-shaking beam moving head light to solve the problem that the existing moving head lights are prone to shaking in windy environments.

[0006] In order to achieve the above-mentioned purpose, the present invention provides an anti-sway beam moving head light, comprising a lamp holder and a U-shaped frame rotatably connected to the lamp holder, wherein the U-shaped frame is rotatably connected to the lamp body, and also comprises a stabilizing mechanism, wherein the stabilizing mechanism is used to prevent the moving head light from swaying in windy conditions, and the stabilizing mechanism is arranged in the lamp holder.

[0007] The principle of this solution is that by setting a stabilizing mechanism, when the moving head light is shaken by wind, the stabilizing mechanism can prevent the moving head light from shaking.

[0008] The technical effect of this solution is that by adding a stabilizing mechanism, the impact of wind on the beam moving head light is effectively reduced, so that the moving head light can maintain a stable operating state in a windy outdoor environment, avoiding damage to the lamp structure and unstable lighting effect caused by shaking.

[0009] Furthermore, the stabilizing mechanism includes an adsorption device and a sensing device matched with the adsorption device, the adsorption device is used to adsorb the moving head light on the ground, and the sensing device is used to sense wind conditions; the adsorption device includes a suction cup arranged at the bottom of the base and an exhaust assembly for extracting air from the suction cup.

[0010] The technical effects of this solution are: (1) The sensing device can monitor the wind conditions in real time, and when there is wind, it can cooperate with the adsorption device to start the adsorption device. (2) When there is wind, the suction cup can be tightly adsorbed to the ground under the action of the exhaust component, preventing the moving head light from shaking in the wind.

[0011] Furthermore, the number of the suction cups is four, and the four suction cups are symmetrically arranged at the bottom of the base.

[0012] The technical effect of this solution is that the provision of four suction cups can make the moving head light more stable when adsorbed on the ground.

[0013] Furthermore, the vacuum assembly includes a vacuum pump with a self-resetting function, and the vacuum pump is connected to the suction cup through an air pipe.

[0014] The technical effect of this solution is that the vacuum pump can extract the air in the suction cup, so that the suction cup forms a state close to a vacuum, making it close to the ground, so that the moving head light can remain stable in a windy environment.

[0015] Furthermore, the vacuum pump includes a shell and a movable plate slidably arranged in the shell, one end of the movable plate is connected to a piston rod, the other end of the movable plate is connected to a spring, and the free end of the spring is fixedly connected to the inner wall of the shell.

[0016] The technical effect of this solution is that when the piston rod is stretched by external force, the spring is stretched to accumulate energy, and when the external force disappears, the spring drives the piston rod to return to its original position.

[0017] Furthermore, the sensing device includes a sensing component and a driving component for driving the piston rod; the sensing component includes a rotating shaft and fan blades, and the fan blades are fixed on the rotating shaft.

[0018] The technical effect of this solution is that when there is wind, the wind force acts on the fan blades, causing them to drive the shaft to rotate. The wind condition is sensed by the above arrangement, thereby linking the drive components.

[0019] Furthermore, there are multiple fan blades, and the multiple fan blades are arranged at equal intervals.

[0020] The technical effect of this solution is that multiple fan blades are arranged at equal distances, which is conducive to better capturing wind power and driving the shaft to rotate.

[0021] Furthermore, the driving assembly includes a turntable coaxially connected to the rotating shaft and an electromagnet arranged on the turntable, the piston rod is provided with a permanent magnet matching the electromagnet, and the electromagnet is connected to a reset spring for resetting it.

[0022] The technical effects of this solution are: (1) When the fan blades drive the shaft to rotate, the turntable coaxially connected to the shaft rotates synchronously. The electromagnet is acted upon by the centrifugal force generated by the rotation of the turntable, and thus moves away from the shaft and toward the permanent magnet. The permanent magnet is attracted by the electromagnet and moves toward the electromagnet, thereby driving the piston rod to extend, and then extracting the air in the suction cup, causing the suction cup to adhere to the ground. (2) The fan blades are used to capture wind force and convert it into the rotational kinetic energy of the shaft and turntable, so that the electromagnet is moved closer to the permanent magnet under the action of centrifugal force, further pulling the piston rod to extend, increasing the extraction force of the air in the suction cup, and improving the suction force of the suction cup on the ground, ensuring that the moving head light can remain stable and not shake in a windy environment.

[0023] Furthermore, the turntable is provided with a slide groove, and the electromagnet is slidably arranged in the slide groove.

[0024] The technical effect of this solution is that the slide groove provides positioning and guiding functions for the movement of the electromagnet.

[0025] Furthermore, a limit baffle is provided at one end of the slide groove away from the rotating shaft.

[0026] The technical effect of this solution is that the limit baffle is used to prevent the electromagnet from moving out of position. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model:

[0034] Example:

The U-shaped frame 2 is rotatably connected to the lamp holder 1, and the lamp body 3 is rotatably connected to the U-shaped frame 2. A stabilizing mechanism 4 is provided on the lamp holder 1, and the stabilizing mechanism 4 is used to prevent the moving head light from swaying in wind.

[0036] See also Figure 3-Figure 5 The stabilizing mechanism 4 includes an adsorption device 41 and a sensing device 42 matched with the adsorption device 41. The adsorption device 41 is used to adsorb the moving head light to the ground, and the sensing device 42 is used to sense the wind condition. The adsorption device 41 includes four suction cups 411 symmetrically arranged at the bottom of the base 1 and an exhaust component for extracting the air in the suction cups 411. The arrangement of four suction cups 411 can make the moving head light more stable when adsorbed to the ground. The sensing device 42 can monitor the wind condition in real time. When there is wind, it can cooperate with the adsorption device 41 to start the adsorption device 41.

[0037] The vacuum assembly includes an air pump 412 with a self-resetting function. The air pump 412 is connected to the suction cup 411 through an air pipe. The air pump 412 can extract the air in the suction cup 411, so that the suction cup 411 is in a state close to a vacuum, so that it is close to the ground, so that the moving head light can remain stable in a windy environment; the air pump 412 includes a shell 4121 and a movable plate 4122 slidably arranged in the shell 4121, one end of the movable plate 4122 is connected to a piston rod 4123, and the other end of the movable plate 4122 is connected to a spring 4124, the free end of the spring 4124 is fixedly connected to the inner wall of the shell 4121, when the piston rod 4123 is stretched by an external force, the spring 4124 is stretched to accumulate energy, and when the external force disappears, the spring 4124 drives the piston rod 4123 to reset.

[0038] The sensing device 42 includes a sensing component and a driving component for driving the piston rod 4123; the sensing component includes a rotating shaft 421 and five fan blades 422, and the five fan blades 422 are fixedly arranged on the rotating shaft 421 at equal distances. When there is wind, the wind acts on the fan blades 422, so that the rotating shaft 421 is driven to rotate. The five fan blades 422 are arranged at equal distances, which is conducive to better capturing wind force and driving the rotating shaft 421 to rotate.

[0039] The driving assembly includes a turntable 423 coaxially connected to the rotating shaft 421 and an electromagnet 424 arranged on the turntable 423. A permanent magnet 425 cooperating with the electromagnet 424 is arranged on the piston rod 4123. The electromagnet 424 is connected to a reset spring 426 for resetting it. The turntable 423 is provided with a slide groove 4231. The electromagnet 424 is slidably arranged in the slide groove 4231. The slide groove 4231 provides positioning and guiding functions for the movement of the electromagnet 425. A limit baffle 427 is arranged at one end of the slide groove 4231 away from the rotating shaft 421. The limit baffle 427 is used to prevent the electromagnet 424 from moving out of position. When the fan blade 422 drives the rotating shaft 421 to rotate, the turntable 423 coaxially connected to the rotating shaft 421 rotates synchronously. The electromagnet 424 is acted on by the centrifugal force generated by the rotation of the turntable 423, so that it moves away from the rotating shaft 421 and approaches the permanent magnet 425. The permanent magnet 425 is attracted by the electromagnet 424 and moves toward the electromagnet 425, thereby driving the piston rod 4123 to extend, and then extract the air in the suction cup 411, so that the suction cup 411 is adsorbed on the ground. The fan blades 422 capture the wind force and convert it into the rotational kinetic energy of the shaft 421 and the turntable 423, so that the electromagnet 424 is moved closer to the permanent magnet 425 under the action of centrifugal force, further pulling the piston rod 4123 to extend, increasing the extraction force of the air in the suction cup 411, and improving the adsorption force of the suction cup 411 on the ground, ensuring that the moving head light can remain stable and not shake in a windy environment.
