Description

Technical Field

[0001] This utility model relates to the field of lighting helmet technology, and in particular to an adjustable lighting helmet for power construction projects. Background Technology

[0002] In power construction projects, lighting equipment is a key factor in ensuring construction safety and improving work efficiency. Among them, the power construction lighting helmet is a hat that protects the head from injuries caused by falling objects and other specific factors. The helmet consists of a shell, liner, chin strap, and accessories.

[0003] In the use of lighting helmets, traditional lighting helmets usually use straps to fix a single light to the top of the brim. When construction workers want to illuminate the work area on both sides, they need to adjust the straps or turn their heads to illuminate the work area, which affects work efficiency and safety.

[0004] Therefore, to address the aforementioned issues of inconvenience in flexibly adjusting the lighting angle, expanding the lighting range, and facilitating the disassembly and assembly of lighting lamps, an adjustable lighting helmet for power construction projects can be designed. During use, through meticulous component design and synergistic action, the lighting helmet enables flexible adjustment of the lighting angle, expansion of the lighting range, and convenient disassembly and assembly of lighting lamps, providing an efficient, safe, and reliable lighting solution for power construction projects. Utility Model Content

[0005] In order to overcome the limitations of traditional lighting helmets in terms of illumination range, which makes it difficult to cover large construction areas, especially in large construction projects where additional lighting equipment is often needed to supplement illumination, which not only increases construction costs but may also lead to delays in construction progress, improvements are urgently needed. Furthermore, the helmets also address the issues of inflexible adjustment of lighting angles, expansion of lighting range, and convenient disassembly and assembly of lighting fixtures.

[0006] The technical solution of this utility model is as follows: an adjustable lighting helmet for power construction projects, comprising a safety helmet, a brim, a cavity, a drive shaft, a driven shaft, an adjusting wheel, a drive gear, a driven gear, a locking ratchet, a fixing block, a locking rod, a limit ring, a return spring, and lighting lamps. A brim is fixedly installed on the side wall of the safety helmet, and a cavity is formed inside the brim. A drive shaft is rotatably installed above the brim, and a driven shaft is rotatably installed above the brim. An adjusting wheel is fixedly installed at the lower end of the drive shaft. A drive gear is fixedly installed on the side wall of the drive shaft, and a driven gear is fixedly installed on the side wall of the driven shaft. A locking ratchet is fixedly installed on the side wall of the driven shaft. A fixing block is fixedly installed inside the cavity, and a locking rod is installed inside the fixing block. A limit ring is fixedly installed on the side wall of the locking rod, and a return spring is fixedly installed on the inner wall of the limit ring. Two sets of lighting lamps are installed above the brim.

[0007] Preferably, during the use of the lighting helmet, when the construction worker rotates the adjustment wheel, it drives the drive shaft and drive gear to rotate, simultaneously driving the upper set of lights to rotate. Since the drive gear meshes with the driven gear, the drive gear can drive the driven gear and driven shaft to rotate in the opposite direction, simultaneously driving the other set of lights to rotate in the opposite direction. This achieves flexible angle adjustment and expands the lighting range. During this process, the driven shaft drives the locking ratchet to rotate. Under the elastic action of the return spring, one end of the locking rod slides along the arc surface of the locking ratchet to the inner wall of the lower gear groove, locking and contacting it. This achieves a locking and limiting effect on both sets of lights, preventing the lights from rotating arbitrarily. In summary, this adjustable lighting head for power construction projects, through its meticulous component design and synergistic action, achieves flexible adjustment of the lighting angle, expansion of the lighting range, and convenient assembly and disassembly of the lights, providing an efficient, safe, and reliable lighting solution for power construction projects.

[0008] Preferably, the driven gear meshes with the driving gear, the locking rod is slidably connected to the fixed block, one end of the locking rod abuts against the inner wall of the tooth groove of the locking ratchet, and one end of the return spring is fixedly connected to the side wall of the fixed block.

[0009] Preferably, an L-shaped actuating rod is fixedly installed at the other end of the locking rod, a guide rod is fixedly installed inside the cavity, a guide seat is installed on the side wall of the guide rod, the guide seat is slidably connected to the guide rod, and the side wall of the guide seat is fixedly connected to the side wall of the L-shaped actuating rod.

[0010] Preferably, two sets of fixing rings are fixedly installed at both ends of the guide rod, and two sets of adjusting springs are fixedly installed at both ends of the guide seat, with one end of the adjusting spring being fixedly connected to the inner wall of the fixing ring.

[0011] Preferably, a mounting bracket is fixedly provided on the upper side wall of the drive shaft. Two sets of mounting brackets are provided. Another set of mounting brackets is fixedly provided on the upper side wall of the driven shaft. A plug-in rod is fixedly provided on the rear side wall of the lighting lamp. A plug-in hole is opened at the front end of the mounting bracket. The plug-in rod is slidably connected to the plug-in hole.

[0012] Preferably, the mounting bracket has a lifting rod inside, which is slidably connected to the mounting bracket. A positioning ring is fixedly installed on the upper side wall of the lifting rod, and a positioning spring is fixedly installed on the bottom wall of the positioning ring. The lower end of the positioning spring is fixedly connected to the upper end of the mounting bracket.

[0013] Preferably, a positioning hole is provided on the side wall of the plug rod, the lifting rod is slidably connected to the positioning hole, and a positioning cylinder is fixedly provided on the inner wall of the mounting bracket, with the lower end of the lifting rod engaging with the positioning cylinder.

[0014] The beneficial effects of this utility model are:

[0015] When the lighting helmet is in use, firstly, when the construction worker rotates the adjustment wheel, it drives the drive shaft and drive gear to rotate, simultaneously rotating the upper set of lights. Since the drive gear meshes with the driven gear, the drive gear can drive the driven gear and driven shaft to rotate in the opposite direction, simultaneously driving the other set of lights to rotate in the opposite direction. This allows for flexible angle adjustment and expansion of the lighting range. During this process, the driven shaft drives the locking ratchet to rotate. Under the elastic action of the return spring, one end of the locking rod slides along the arc surface of the locking ratchet to the inner wall of the lower gear groove, locking and contacting it. This achieves a locking and limiting effect on both sets of lights, preventing the lights from rotating arbitrarily. In summary, this adjustable lighting head for power construction projects, through its meticulous component design and synergistic action, achieves flexible adjustment of the lighting angle, expansion of the lighting range, and convenient installation and removal of the lights, providing an efficient, safe, and reliable lighting solution for power construction projects.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

There is a driven shaft 5, an adjusting wheel 6 is fixedly installed at the lower end of the driving shaft 4, a driving gear 7 is fixedly installed on the side wall of the driving shaft 4, a driven gear 8 is fixedly installed on the side wall of the driven shaft 5, a locking ratchet 9 is fixedly installed on the side wall of the driven shaft 5, a fixing block 10 is fixedly installed inside the cavity 3, a locking rod 11 is installed inside the fixing block 10, a limit ring 12 is fixedly installed on the side wall of the locking rod 11, a return spring 13 is fixedly installed on the inner wall of the limit ring 12, and two sets of lighting lamps 14 are installed above the cap brim 2.

[0027] Please see Figure 2 and Figure 6 The driven gear 8 meshes with the driving gear 7, the locking rod 11 is slidably connected to the fixed block 10, one end of the locking rod 11 is in contact with the inner wall of the tooth groove of the locking ratchet 9, and one end of the return spring 13 is fixedly connected to the side wall of the fixed block 10. Under the elastic action of the return spring 13, one end of the locking rod 11 can slide down along the arc surface of the locking ratchet 9 to the inner wall of the lower tooth groove and achieve locking contact with it.

[0028] Please see Figure 5 and Figure 8An L-shaped actuating rod 15 is fixedly installed at the other end of the locking rod 11. A guide rod 16 is fixedly installed inside the cavity 3. A guide seat 17 is installed on the side wall of the guide rod 16. The guide seat 17 is slidably connected to the guide rod 16. The side wall of the guide seat 17 is fixedly connected to the side wall of the L-shaped actuating rod 15. The L-shaped actuating rod 15 can drive the guide seat 17 to move smoothly along the guide rod 16. At the same time, it can drive one end of the locking rod 11 to disengage from the inner wall of the tooth groove of the locking ratchet 9, so that the locking ratchet 9 is unlocked. Two sets of fixing rings 18 are fixedly installed at both ends of the guide rod 16. Two sets of adjusting springs 19 are fixedly installed at both ends of the guide seat 17. One end of the adjusting spring 19 is fixedly connected to the inner wall of the fixing ring 18. Under the elastic action of the adjusting spring 19, the guide seat 17 can be driven to move along the guide rod 16 to achieve the effect of reset movement.

[0029] Please see Figure 3 and Figure 4 A mounting bracket 20 is fixedly installed on the upper side wall of the drive shaft 4. Two sets of mounting brackets 20 are provided; another set is fixedly installed on the upper side wall of the driven shaft 5. A plug-in rod 21 is fixedly installed on the rear side wall of the lighting lamp 14. A plug-in hole 22 is opened at the front end of the mounting bracket 20. The plug-in rod 21 is slidably connected to the plug-in hole 22. By inserting the plug-in rod 21 at the rear end of the lighting lamp 14 into the plug-in hole 22, the lighting lamp 14 can be initially installed at the front end of the mounting bracket 20. A lifting rod 23 is provided inside the mounting bracket 20. The lifting rod 23 is slidably connected to the mounting bracket 20. A positioning ring 24 is fixedly installed on the upper side wall of the lifting rod 23. A positioning ring 24 is fixedly installed on the bottom wall of the positioning ring 24. A positioning spring 25 is fixedly installed, and the lower end of the positioning spring 25 is fixedly connected to the upper end of the mounting bracket 20. When the lifting rod 23 is released, under the elastic action of the positioning spring 25, the lifting rod 23 can be driven to move downward to reset. A positioning hole 26 is opened on the side wall of the plug rod 21, and the lifting rod 23 is slidably connected to the positioning hole 26. A positioning cylinder 27 is fixedly installed on the inner wall of the mounting bracket 20, and the lower end of the lifting rod 23 is engaged with the positioning cylinder 27. When the lifting rod 23 is released, under the elastic action of the positioning spring 25, the lifting rod 23 can be driven to insert downward into the positioning hole 26 and the positioning cylinder 27, thereby achieving the locking and positioning effect of the plug rod 21 and the lighting lamp 14.

[0030] When the lighting helmet is in use, firstly, when the worker rotates the adjusting wheel 6, it drives the drive shaft 4 and drive gear 7 to rotate, simultaneously rotating the upper set of lighting lamps 14. Since the drive gear 7 meshes with the driven gear 8, the drive gear 7 can drive the driven gear 8 and driven shaft 5 to rotate in the opposite direction, simultaneously driving the other set of lighting lamps 14 to rotate in the opposite direction. This allows for flexible angle adjustment and expands the lighting range.

[0031] During this process, the driven shaft 5 can drive the locking ratchet 9 to rotate. Under the elastic action of the return spring 13, one end of the locking rod 11 can slide down along the arc surface of the locking ratchet 9 to the inner wall of the lower gear groove and lock against it, thereby achieving the locking and limiting effect on the two sets of lighting lamps 14, and thus preventing the lighting lamps 14 from rotating randomly.

[0032] When it is necessary to reset the two sets of lights 14, firstly, push the L-shaped lever 15 forward. At this time, the L-shaped lever 15 can drive the guide seat 17 to move smoothly along the guide rod 16. At the same time, it can drive one end of the locking lever 11 to disengage from the inner wall of the tooth groove of the locking ratchet 9, causing the locking ratchet 9 to be unlocked. Then, rotating the adjusting wheel 6 in the opposite direction can drive the two sets of lights 14 to achieve the effect of reversing and resetting.

[0033] Furthermore, when installing the lighting lamp 14, firstly, pull the lifting rod 23 upwards. At this time, the positioning spring 25 is compressed and deformed. Then, insert the plug-in rod 21 at the rear end of the lighting lamp 14 into the plug-in hole 22. Subsequently, release the lifting rod 23. Under the elastic action of the positioning spring 25, the lifting rod 23 can be driven downwards into the positioning hole 26 and the positioning cylinder 27, thereby achieving a locking and positioning effect on the plug-in rod 21 and the lighting lamp 14. When disassembling the lighting lamp 14, the operation is reversed, thus achieving a convenient disassembly and assembly effect for the lighting lamp 14.

[0034] In summary, this adjustable lighting head for power construction projects, through its meticulous component design and synergistic effect, achieves flexible adjustment of the lighting angle, expansion of the lighting range, and convenient installation and removal of the lighting lamp 14, providing an efficient, safe, and reliable lighting solution for power construction projects.

[0035] Through the above steps, during the use of the lighting helmet, firstly, when the construction worker rotates the adjusting wheel 6, it can drive the drive shaft 4 and drive gear 7 to rotate, and at the same time drive the upper set of lighting lamps 14 to rotate. Since the drive gear 7 meshes with the driven gear 8, the drive gear 7 can drive the driven gear 8 and driven shaft 5 to rotate in the opposite direction, and at the same time drive the other set of lighting lamps 14 to rotate in the opposite direction, thereby achieving flexible angle adjustment and expanding the lighting range. During this process, the driven shaft 5 can drive the locking ratchet 9 to rotate, and in the subsequent... Under the elastic action of the positioning spring 13, one end of the locking rod 11 can slide down along the arc surface of the locking ratchet 9 to the inner wall of the lower gear groove and lock against it, thereby achieving the locking and limiting effect on the two sets of lighting lamps 14, and thus preventing the lighting lamps 14 from rotating arbitrarily. In summary, this adjustable lighting head for power construction projects, through its precise component design and synergistic action, achieves flexible adjustment of the lighting angle, expansion of the lighting range, and convenient disassembly and assembly of the lighting lamps 14, providing an efficient, safe, and reliable lighting solution for power construction projects.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
