[0025] This utility model provides, for example Figures 1-5 The telescopic adjustable cantilever work light shown includes a sleeve bracket 3 and a lifting and reinforcing sleeve 5 that is sleeved and fixed to the outside of the top of the sleeve bracket 3. A screw hole is connected at the center of the front end of the lifting and reinforcing sleeve 5 to the inside of the front end of the sleeve bracket 3. A hand-tightening height-setting screw 4 is threaded into the screw hole. A telescopic bracket 6 is inserted into the sleeve bracket 3, and the telescopic bracket 6 can rotate clockwise and counterclockwise and move up and down within the lifting and reinforcing sleeve 5 and the sleeve bracket 3. A U-shaped corner sleeve 7 is welded to the top of the telescopic bracket 6. A rotating connecting block 9 is provided, which is connected to the U-shaped corner sleeve 7 by a hand-tightening fixed angle screw 8. A metal cantilever 10 is welded to the right end of the rotating connecting block 9. A lamp body fixing sleeve 12 is sleeved and fixed to the outside of the right end of the metal cantilever 10. A working lamp body 13 is provided at the right end of the lamp body fixing sleeve 12. A welding fixing sleeve 2 is sleeved to the outside of the bottom end of the sleeve bracket 3. A mounting base 1 is provided at the bottom end of the welding fixing sleeve 2. The welding fixing sleeve 2 is fixed to both the sleeve bracket 3 and the mounting base 1 by welding. The connection is made so that rubber anti-slip pads can be attached to the outer wall of the bottom of the mounting base 1 as needed. After the hand-tightened height-fixing screw 4 is manually tightened, the screw rod can press tightly against the outer wall of the front end of the telescopic bracket 6 to lock the height of the telescopic bracket 6. The length of the telescopic bracket 6 is equal to the length of the sleeve bracket 3, and the bottom end of the sleeve bracket 3 is sealed. In terms of height adjustment, the telescopic bracket 6 is inserted into the sleeve bracket 3 and can move up and down within the space defined by the lifting reinforcement sleeve 5 and the sleeve bracket 3. When it is necessary to adjust the height of the work lamp body 13, simply loosen the hand-tightened height-fixing screw 4, and the telescopic bracket 6 can slide freely to the required height within the sleeve bracket 3. Then tighten the hand-tightened height-fixing screw 4, and the screw rod presses tightly against the outer wall of the front end of the telescopic bracket 6 to lock the height of the telescopic bracket 6. This design allows the work lamp body 13 to be quickly and conveniently adjusted to a suitable height according to the needs of the actual work scene, meeting the lighting height requirements of different users in different environments.
[0026] like Figure 1 , Figure 2 and Figure 3 As shown, during the tightening process of the hand-tightened fixed-angle screw 8, the opening of the U-shaped corner sleeve 7 will gradually shrink. After the hand-tightened fixed-angle screw 8 is fully tightened, the U-shaped corner sleeve 7 will be clamped on the outside of the front and rear ends of the rotating connecting block 9, so that the rotating connecting block 9 is locked in the U-shaped corner sleeve 7 and cannot rotate. In terms of angle adjustment, the rotating connecting block 9 is provided in the U-shaped corner sleeve 7 welded to the top of the telescopic bracket 6. The rotating connecting block 9 is connected to the U-shaped corner sleeve 7 by the hand-tightened fixed-angle screw 8. When it is necessary to change the illumination angle of the work lamp body 13, the hand-tightened fixed-angle screw 8 is loosened, and the rotating connecting block 9 can then be placed in the U-shaped corner sleeve. The U-shaped sleeve 7 rotates freely within the U-shaped sleeve, thereby driving the welded metal cantilever 10 and the work lamp body 13 at the right end of the metal cantilever 10 to adjust their angles. After adjusting to a suitable lighting angle, the hand-tightened fixed angle screw 8 is tightened. During the tightening process, the opening of the U-shaped sleeve 7 gradually shrinks, eventually causing the U-shaped sleeve 7 to be tightly clamped on the front and rear ends of the rotating connecting block 9, locking the rotating connecting block 9 in the U-shaped sleeve 7, thereby fixing the lighting angle of the work lamp body 13. In this way, the work lamp body 13 can flexibly adjust its angle in the horizontal direction to provide precise lighting for different work areas.
[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the working lamp body 13 is composed of a lampshade 14, a light-transmitting protective plate 15, an LED light board 16, and LED beads 17. The lampshade 14 is fixed to the right end of the lamp body fixing sleeve 12. The bottom end of the lampshade 14 is open. The LED light board 16 is fixed to the inner wall of the top end of the lampshade 14 by screws. Multiple LED beads 17 are evenly arranged at the bottom end of the LED light board 16. The light-transmitting protective plate 15 is fixed inside the opening at the bottom end of the lampshade 14. A battery holder 19 is fixed to the top end of the lampshade 14. A control button 18 is provided inside the front end of the battery holder 19. A controller is provided inside the left end of the battery holder 19. The controller is electrically connected to the LED light board 16 through wires. In terms of lighting function, the working lamp body 13 is composed of a lampshade 14, a light-transmitting protective plate 15, an LED light board 16, and LED beads 17. The lampshade 14 is fixed to the right end of the lamp body fixing sleeve 12. The lampshade 14 provides protection and support for its internal components. An LED light board 16 is fixed to the inner wall of the top of the lampshade 14 with screws. Multiple LED beads 17 are evenly arranged at the bottom of the LED light board 16 as light sources. A light-transmitting protective plate 15 fixed inside the bottom opening of the lampshade 14 can protect the internal LED beads 17 and also allow the light to be evenly diffused, providing a soft lighting effect. At the same time, the battery holder 19 fixed at the top of the lampshade 14 provides power support for the entire working lamp body 13. The control button 18 inside the front of the battery holder 19 makes it convenient for users to operate the working lamp body 13 to turn it on and off. The controller inside the left end of the battery holder 19 is electrically connected to the LED light board 16 through wires to realize the current control of the LED light board 16, thereby controlling the light emission state of the LED beads 17 and ensuring that the working lamp body 13 can provide stable lighting services.
[0028] like Figure 1 and Figure 5As shown, an anti-sinking device 11 is fixedly fitted to the outer side of the top of the telescopic bracket 6. The anti-sinking device 11 includes a metal fixing ring 20, a horizontal bracket 21, a fixed-height support nut 22, a support screw 23, and a U-shaped arm sleeve 24. The metal fixing ring 20 is fitted and fixed to the outside of the telescopic bracket 6. The horizontal bracket 21 is welded to the right end of the metal fixing ring 20. A through hole is provided inside the right side of the center of the horizontal bracket 21. The support screw 23 is inserted into the through hole. The fixed-height support nut 22 is threaded onto the outside of the support screw 23. The fixed-height support nut 22 is blocked on the outer wall of the top of the horizontal bracket 21. The U-shaped arm sleeve 24 is welded to the top of the support screw 23. The U-shaped arm sleeve 24 is opened upward and fitted onto the outside of the metal cantilever 10. The support screw 23 can move up and down in the through hole. The fixed-height support nut 22 can rotate clockwise and counterclockwise through the thread action. The support screw 23 moves up and down externally. As the fixed-height support nut 22 moves downward, it pushes the support screw 23 upward through the blocking action of the horizontal bracket 21. The fixed-height support nut 22, which is threaded onto the outside of the support screw 23, is a key component for achieving the functions of anti-sinking and height fine adjustment. The fixed-height support nut 22 can move up and down externally on the support screw 23 by rotating clockwise and counterclockwise, using the transmission principle of the thread. When the fixed-height support nut 22 rotates downward, it cannot continue to move downward because it is blocked by the outer wall of the top of the horizontal bracket 21. At this time, according to the principle that forces act in pairs, the horizontal bracket 21 will generate an upward reaction force on the fixed-height support nut 22, thereby pushing the support screw 23 upward. Conversely, when the fixed-height support nut 22 rotates upward, the support screw 23 will move downward under its influence.
[0029] like Figure 1 and Figure 5 As shown, when the illumination angle of the work lamp body 13 is adjusted by the rotating connecting block 9 at the left end of the metal cantilever 10 and the angle is locked by tightening the hand-tightening angle screw 8, the weight of the metal cantilever 10 and the work lamp body 13 will exert a downward force on the rotating connecting block 9. Under prolonged action, the right end of the rotating connecting block 9 is prone to angle sinking. At this time, the U-shaped arm sleeve 24, through the support of the support screw 23, can provide an upward support force for the metal cantilever 10, effectively counteracting the angle sinking trend caused by gravity, thereby maintaining the illumination of the work lamp body 13. In addition to ensuring the stability of the angle, the height of the metal cantilever 10 can also be finely adjusted by adjusting the position of the fixed height support nut 22 on the support screw 23. This fine-tuning function is very practical in actual use. When the work scene has slight changes in the requirements for lighting height, there is no need to readjust the angle lock of the rotating connecting block 9. Simply rotate the fixed height support nut 22, and the support screw 23 can drive the U-shaped arm sleeve 24 and the metal cantilever 10 to make fine-tuning of the height to meet the precise requirements for lighting height and angle in different work scenes.
[0030] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
