[0005] In order to increase the applicability of the searchlight, the present application provides a rotating searchlight.

[0006] The present application provides a rotating searchlight adopting the following technical solution:

[0007] A rotating searchlight comprises a searchlight body and a rotating base, and also comprises a bracket and a mounting platform. The bracket is fixedly arranged on the rotating shaft of the rotating base, the rotating base is used to drive the bracket to rotate, and the mounting platform is detachably connected to the bracket. The searchlight body comprises a shell and a lighting component arranged in the shell, and the shell is detachably connected to the mounting platform.

[0008] By adopting the above technical solution, the user can remove the searchlight body from the mounting platform for use. After the searchlight body is removed, the weight will be lighter than the entire searchlight with a rotating base, and it can be easier to hold in the hand, making it more convenient to carry out for lighting. When the searchlight is installed on the mounting platform, it can be placed on the platform for use, thereby increasing the applicability of the searchlight.

[0009] Preferably, the bottom surface of the shell is concave to form a wedge-shaped groove and a slot, the surface of the mounting platform is convex to form a wedge-shaped block, the wedge block and the wedge-shaped groove slide together, the mounting platform is threaded with an insert block, and the top of the insert block is used to insert into the slot.

[0010] By adopting the above technical solution, the wedge-shaped groove on the mounting table is aligned with the wedge-shaped block to slide, so that the shell is initially connected to the mounting table, and then the operator rotates the plug block to insert the plug block into the slot to completely lock the shell.

[0011] Preferably, the searchlight body also includes a fan assembly, and the fan assembly is detachably connected to the rear end of the shell, and an air duct is opened through the bottom end of the shell. When the fan assembly is started, air enters the air duct and air exits the rear end of the shell; an avoidance groove is opened through the mounting platform, and when the plug block is inserted into the slot, the avoidance groove faces the air duct.

[0012] By adopting the above technical solution, when the lighting component is started, heat is generated, causing the air in the shell to be heated. When the fan component is started, cold air from the outside enters from the air duct to replace the hot air in the shell. The hot air in the shell is continuously brought out by the fan component, thereby achieving cooling of the lighting component.

[0013] Preferably, the lighting assembly comprises an LED lamp, a reflective cup and a dimming switch arranged on the housing, the reflective cup is used to reflect and focus the light of the LED lamp into a concentrated light beam, and the dimming switch is used to adjust the brightness of the LED lamp.

[0014] By adopting the above technical solution, when the brightness of the LED lamp is dimmed, the heat generated by the LED lamp will also decrease, and when the brightness of the LED lamp is brightened, the heat generated by the LED lamp will also increase; because the fan assembly also has a certain weight, when holding the searchlight, the operator can choose whether to disassemble the fan assembly according to the actual lighting conditions. After the fan assembly is disassembled, the LED lamp cannot play a higher brightness, but the weight of the searchlight will become lighter; when the fan assembly is installed on the shell, the LED lamp can play a higher brightness, but the weight of the searchlight will become heavier.

[0015] Preferably, a limiting component is also included, the dimmer switch is a sliding dimmer switch, the sliding direction of the sliding dimmer switch is parallel to the rotation axis direction of the fan assembly, and the limiting component is used to drive the dimmer switch to move to the end where the brightness of the LED lamp is slightly dimmer after the fan assembly is detached from the housing.

[0016] By adopting the above technical solution, in order to prevent the operator from forgetting to adjust the brightness after disassembling the fan assembly, the lighting assembly will not be effectively cooled, resulting in excessive temperature, thereby affecting the service life of the lighting assembly; the limiting component better solves the above problem, and can actively turn the dimmer switch to the end where the brightness of the LED light is slightly darker after the fan assembly is disassembled.

[0017] Preferably, the limiting assembly includes a spring and a lever, the lever is arranged in an L shape, and the lever slides on the shell along a sliding direction parallel to the sliding direction of the sliding dimmer switch, the long end of the lever faces the side of the fan assembly, and the short end of the lever is located on the side of the sliding dimmer switch away from the fan assembly, and the spring is used to drive the lever to always move toward the side of the fan assembly. When the fan assembly is installed on the shell, the long end of the lever abuts against the fan assembly, and the short end of the lever is located outside the moving path of the sliding dimmer switch; when the fan assembly is detached from the shell and the lever, the short end of the lever abuts against the sliding dimmer switch and drives the sliding dimmer switch to move to the end where the brightness of the LED lamp is slightly dimmer.

[0018] By adopting the above technical solution, when the fan assembly is installed on the shell, the fan assembly will abut against the lever, which will push the lever to overcome the elastic force of the spring and move toward the front end of the shell. At this time, the short end of the lever will be located outside the moving path of the sliding dimmer switch, and the lever will not have any impact on the sliding dimmer switch; when the fan assembly is removed, the lever moves toward the rear end of the shell under the action of the spring. At this time, the short end of the lever will abut against the sliding dimmer switch to drive the sliding dimmer switch to move, so that the dimmer switch automatically moves to the end where the brightness of the LED lamp is slightly dimmer.

[0019] Preferably, a dustproof net is provided on the air duct.

[0020] By adopting the above technical solution, the dustproof net can block the dust from entering the shell and reduce the accumulation of dust in the shell.

[0021] The technical effects of this utility model are mainly reflected in the following aspects:

[0022] 1. In the utility model, the user can remove the searchlight body from the mounting platform for use. After the searchlight body is removed, it is lighter than the entire searchlight with a rotating base, and can be held more easily in the hand, making it more convenient to carry out for lighting. When the searchlight is installed on the mounting platform, it can be placed on the platform for use, thereby increasing the applicability of the searchlight;

[0023] 2. The utility model can prevent the operator from forgetting to adjust the brightness after disassembling the fan assembly by setting a limiting component, which may cause the lighting assembly to overheat due to lack of effective heat dissipation, thereby affecting the service life of the lighting assembly; the limiting component can actively turn the dimmer switch to the end where the brightness of the LED light is slightly darker after the fan assembly is disassembled.

One end of the bolt passes through the fork at the top of the bracket 13 and is threadedly connected to the mounting platform 14. The operator can adjust the inclination angle of the mounting platform 14 so that the searchlight body 2 can irradiate at different angles. In conjunction with the rotating base 1, the searchlight body 2 can rotate continuously.

[0031] Reference Figure 1 and Figure 2 The user can remove the searchlight body 2 from the mounting platform 14 for use. After the searchlight body 2 is removed, it will be lighter than the entire searchlight with the rotating base 1, and it can be easier to hold in the hand, making it more convenient to carry out for lighting. When the searchlight is installed on the mounting platform 14, it can be placed on the platform for use, thereby increasing the applicability of the searchlight.

[0032] Reference Figure 1 and Figure 2 The top of the housing 21 has a handle 216, the bottom of the housing 21 is concavely formed with a wedge-shaped groove 211 and a slot 212, the surface of the mounting platform 14 is convexly formed with a wedge-shaped block 141, the wedge-shaped block 141 and the wedge-shaped groove 211 are slidably matched with each other, and the mounting platform 14 is threadedly connected with an insert block 142, and the top of the insert block 142 is used to be inserted into the slot 212. The wedge groove 211 on the mounting platform 14 is aligned with the wedge block 141 and slides, so that the housing 21 is initially connected to the mounting platform 14, and then the operator rotates the insert block 142 to insert the insert block 142 into the slot 212, and the housing 21 is completely locked.

[0033] Reference Figure 1 and Figure 2 The searchlight body 2 also includes a fan assembly 4, which is detachably connected to the rear end of the shell 21. An air duct 213 is provided at the bottom of the shell 21. When the fan assembly 4 is started, air enters the air duct 213 and air exits from the rear end of the shell 21. An avoidance slot 143 is provided on the mounting platform 14. When the plug 142 is inserted into the slot 212, the avoidance slot 143 faces the air duct 213. When the lighting assembly 3 is started, heat is generated, so that the air in the shell 21 is heated. When the fan assembly 4 is started, cold air from the outside enters from the air duct 213 to replace the hot air in the shell 21. The hot air in the shell 21 is continuously taken out by the fan assembly 4, thereby cooling the lighting assembly 3.

[0034] Reference Figure 1 and Figure 2The fan assembly 4 includes an end cover 41 and a fan 42. The end cover 41 is plugged into the rear end of the housing 21. The end cover 41 and the housing 21 can be further fixed by bolts. The fan 42 is rotatably arranged in the end cover 41, and the fan 42 rotates to generate wind force.

[0035] Reference Figure 1 and Figure 2 The lighting assembly 3 includes an LED lamp 31, a reflective cup 32 and a dimming switch arranged on the housing 21. The reflective cup 32 is used to reflect and focus the light of the LED lamp 31 into a concentrated light beam, and the dimming switch is used to adjust the brightness of the LED lamp 31.

[0036] Reference Figure 1 and Figure 2 When the brightness of the LED lamp 31 is dimmed, the heat generated by the LED lamp 31 will also decrease, and when the brightness of the LED lamp 31 is brightened, the heat generated by the LED lamp 31 will also increase; since the fan assembly 4 also has a certain weight, when holding the searchlight, the operator can choose whether to disassemble the fan assembly 4 according to the actual lighting conditions. After the fan assembly 4 is disassembled, the LED lamp 31 cannot exert a higher brightness, but the weight of the searchlight will become lighter; when the fan assembly 4 is installed on the shell 21, the LED lamp 31 can exert a higher brightness, but the weight of the searchlight will become heavier.

[0037] Reference Figure 1 and Figure 2 Among them, the fan assembly 4 and the lighting assembly 3 are both equipped with power supplies and corresponding on and off switches.

[0038] Reference Figure 1 and Figure 2 , and also includes a limiting component 5, the dimmer switch is a sliding dimmer switch 33, the sliding direction of the sliding dimmer switch 33 is parallel to the rotation axis direction of the fan assembly 4, and the limiting component 5 is used to drive the dimmer switch to the end where the brightness of the LED lamp 31 is slightly darker after the fan assembly 4 is separated from the shell 21.

[0039] Reference Figure 1 and Figure 2 In order to prevent the operator from forgetting to adjust the brightness after removing the fan assembly 4, the lighting assembly 3 will not be effectively cooled, resulting in excessive temperature, thereby affecting the service life of the lighting assembly 3; the limiting assembly 5 better solves the above problem. After the fan assembly 4 is removed, the dimmer switch can be actively turned to the end where the brightness of the LED lamp 31 is slightly darker.

[0040] Reference Figure 1 and Figure 2The limiting assembly 5 includes a spring 51 and a lever 52. The lever 52 is L-shaped.
