Description

Technical Field

[0001] This utility model relates to the field of solar wall lamp technology, and in particular to a detachable solar wall lamp. Background Technology

[0002] Currently, with the global energy structure transformation and the advancement of "dual carbon" goals, solar wall lights are widely used in the field of outdoor lighting due to their energy-saving and environmentally friendly characteristics. These wall lights convert solar energy into electricity through photovoltaic panels, which not only effectively reduces dependence on the traditional power grid and reduces carbon emissions, but also has significant installation convenience and cost advantages in scenarios such as park trails, courtyard walls, and community security because there is no need to lay complex wiring.

[0003] However, most existing solar wall lights use bolts or embedded clips for fixing. Once installed on the wall, disassembly requires the use of professional tools to repeatedly tighten the bolts, which is cumbersome and time-consuming. The clip structure lacks an easy unlocking design, and uneven force during disassembly can easily cause the clips to break, making it impossible to disassemble or reinstall the light fixture. This makes it extremely inconvenient to maintain, repair, replace parts, or relocate solar wall lights, greatly increasing the cost and difficulty of later maintenance and seriously restricting the ease of use and widespread application of solar wall lights. Utility Model Content

[0004] The disassembly of solar wall lights requires repeated tightening of bolts with specialized tools, resulting in a cumbersome and time-consuming process. Furthermore, the lack of a convenient unlocking design in the snap-fit ​​structure makes it prone to breakage due to uneven force during disassembly, preventing proper removal or reinstallation. This makes maintenance, repair, component replacement, and relocation of solar wall lights extremely inconvenient, significantly increasing maintenance costs and difficulty. This severely hinders the ease of use and widespread application of solar wall lights. This invention provides a detachable solar wall light that offers convenient and efficient installation and disassembly, solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a detachable solar wall lamp, including a lamp body, a mounting bracket on the back of the lamp body, a slot on the side of the mounting bracket near the lamp body, a plug fixedly mounted on the back of the lamp body, a connecting post fixedly mounted on the surface of the plug, a plurality of positioning holes evenly distributed on the surface of the connecting post, a worm gear rotatably mounted on the inner center of the mounting bracket, a groove on the bottom of the mounting bracket, a worm rotatably mounted on the inner side of the groove, the upper end of the worm meshing with the side of the worm gear, four arc-shaped grooves evenly distributed on the surface of the worm gear, four sliding grooves on the surface of the mounting bracket, an I-shaped slider slidably mounted inside each of the sliding grooves, a drive rod fixedly mounted on the inner side of the I-shaped slider, four drive rods respectively located inside the arc-shaped grooves, a limit rod fixedly mounted on the side of the I-shaped slider away from the drive rod, the limit rod fitting into the positioning hole.

[0006] Preferably, the plug is inserted into the inside of the slot, and a telescopic rod is provided on one side of the bottom of the mounting bracket. One side of the telescopic rod passes through the groove and is fixedly installed on one end of the worm gear.

[0007] The telescopic rod is connected to the worm gear through a groove, allowing for manual rotation to drive the worm gear transmission and enabling convenient operation of the worm gear linkage limit rod.

[0008] Preferably, a knob is fixedly installed at the end of the telescopic rod away from the worm gear, a limiting piece is fixedly installed on the inner side of the groove, and when the insert is inserted into the slot and fits against the limiting piece, the positioning hole on the surface of the connecting column corresponds to the limiting insert.

[0009] The knob, fixed to the end of the telescopic rod, allows for manual force application and precise control of the telescopic rod's rotation angle, enabling quick alignment and locking of the limit rod and positioning hole.

[0010] Preferably, when the worm gear rotates clockwise, the drive rod causes the I-shaped slider to gradually move closer to the connecting column along the slide groove.

[0011] By using a worm gear that rotates clockwise, its arc-shaped groove drives the drive rod to move the I-shaped slider, allowing the limit rod to be inserted into the positioning hole to lock the lamp body and the mounting bracket.

[0012] Preferably, when the worm gear rotates counterclockwise, the drive rod causes the I-shaped slider to move away from the connecting column along the slide groove.

[0013] By using a worm gear that rotates counterclockwise, its arc-shaped groove drives the drive rod to move the I-shaped slider, allowing the limit plug to disengage from the positioning hole and enabling quick disassembly of the lamp body from the mounting bracket.

[0014] Preferably, a solar panel is fixedly installed on the top of the lamp body, and mounting holes are provided at the four corners of the mounting frame. Screws can be provided on the inside of the mounting holes to fix the mounting frame in a designated position.

[0015] With the installation holes, the mounting bracket can be securely fixed to a designated location such as a wall using screws, providing a reliable support base for the lamp body installation.

[0016] Preferably, a fixing plate is fixedly installed on one side of the bottom of the mounting bracket, and a locking block is fixedly installed on the surface of the telescopic rod. The surface of the fixing plate has a through hole, and multiple slots are evenly provided on the side wall of the through hole. The locking block and the slots fit together.

[0017] This utility model has the following advantages:

[0018] 1. The mounting bracket features a worm gear meshing transmission structure and a linkage mechanism between the I-shaped slider, drive rod, and limit rod. Rotating the knob drives the worm gear to rotate, and the inner wall of the worm gear's arc-shaped groove generates a radial thrust on the drive rod, causing the I-shaped slider to slide along the groove. During installation, the insert block is inserted into the slot and fits against the limit piece, with the positioning hole corresponding to the limit rod. Rotating the knob clockwise inserts the limit rod into the positioning hole and locks the lamp body. During disassembly, rotating the knob counterclockwise disengages the limit rod from the positioning hole and pulls it out of the lamp body. The worm gear's self-locking characteristic ensures stability. The arc-shaped groove and drive rod work together to achieve synchronous movement of multiple limit rods. Disassembly and assembly can be completed simply by rotating the knob, improving efficiency, avoiding component damage, and reducing maintenance difficulty and cost.

[0019] 2. By designing the mounting bracket and lamp body as a detachable plug-in structure, the mounting bracket is fixed to the wall through the four corner mounting holes. The lamp body can be quickly positioned by the cooperation of the plug and slot. Combined with the worm gear driven limit plug locking mechanism, the lamp body forms a stable mechanical connection after installation. After the mounting bracket is fixed to the wall once, there is no need to repeat the operation of the wall fixing structure when maintaining or replacing the lamp body. The lamp body can be disassembled and installed by simply turning the knob. This solves the problem of the lamp being difficult to disassemble and maintain after it is fixed to the wall in the existing technology. At the same time, it reduces the risk of repeated damage to the wall structure and improves the maintainability of the product and the flexibility of relocation of the installation position.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 A detachable solar wall lamp includes a lamp body 1, a mounting bracket 3 on the back of the lamp body 1, a slot 8 on the side of the mounting bracket 3 near the lamp body 1, an insert 5 fixedly installed on the back of the lamp body 1, a connecting post 6 fixedly installed on the surface of the insert 5, and multiple positioning holes 7 evenly opened on the surface of the connecting post 6.

[0029] A worm gear 9 is rotatably mounted on the inner center of the mounting bracket 3. A groove 10 is provided at the bottom of the mounting bracket 3. A worm 11 is rotatably mounted on the inner side of the groove 10. The upper end of the worm 11 is meshed with the side of the worm gear 9. Four arc-shaped grooves 14 are evenly provided on the surface of the worm gear 9. Four sliding grooves 16 are provided on the surface of the mounting bracket 3. I-shaped sliders 17 are slidably mounted inside the sliding grooves 16. Through the meshing transmission between the worm gear 9 and the worm 11, when the knob 13 is turned to drive the worm 11 to rotate, the axial force of the worm 11 is transmitted to the worm gear 9 through the tooth surface, causing the worm gear 9 to make a circular motion around the axis. Due to the trajectory design of the arc-shaped grooves 14 on the surface of the worm gear 9, its inner wall generates a periodic radial thrust on the drive rod 15, forcing the drive rod 15 to drive the I-shaped sliders 17 to make a linear reciprocating motion along the sliding grooves 16.

[0030] A drive rod 15 is fixedly installed on the inner side of the I-shaped slider 17. Four drive rods 15 are respectively located inside the arc-shaped groove 14. Through the meshing transmission structure of the worm gear 9 and worm 11 inside the mounting bracket 3 and the linkage mechanism of the I-shaped slider 17, drive rods 15, and limit rods 18, rotating the knob 13 drives the worm gear 9 to rotate. The inner wall of the arc-shaped groove 14 of the worm gear 9 generates a radial thrust on the drive rod 15, causing the I-shaped slider 17 to slide along the slide groove 16. A limit rod 18 is fixedly installed on the side of the I-shaped slider 17 away from the drive rod 15. The limit rod 18 and the positioning hole When the 7 parts are aligned, the insert 5 is inserted into the slot 8 and fits with the limiting piece 19. The positioning hole 7 corresponds to the limiting rod 18. When the knob 13 is turned clockwise, the limiting rod 18 is inserted into the positioning hole 7 and locks the lamp body 1. When disassembling, the knob 13 is turned counterclockwise. After the limiting rod 18 is disengaged from the positioning hole 7, the lamp body 1 is pulled out. The self-locking characteristic of the worm gear 9 and worm 11 ensures stability. The arc groove 14 cooperates with the drive rod 15 to realize the synchronous action of multiple sets of limiting rods 18. Disassembly and assembly can be completed by simply turning the knob 13, which improves efficiency, avoids damage to parts, and reduces maintenance difficulty and cost.

[0031] Please see Figures 2-6 The insert 5 is inserted and installed inside the slot 8. A telescopic rod 12 is located on one side of the bottom of the mounting bracket 3. The telescopic rod 12 has a built-in locking block, preventing the two rods from rotating relative to each other. One side of the telescopic rod 12 passes through the groove 10 and is fixedly installed at one end of the worm gear 11. A knob 13 is fixedly installed at the end of the telescopic rod 12 away from the worm gear 11. The knob 13 is fixed to the end of the telescopic rod 12 passing through the groove 10 and is linked to the worm gear 11. When the knob 13 is manually rotated, the telescopic rod 12 transmits torque to the worm gear 11, driving the meshing worm wheel 9 to rotate. This, in turn, through the cooperation of the arc-shaped groove 14 and the drive rod 15, causes the I-shaped slider to rotate. 17 drives the limiting rod 18 to move linearly. The limiting piece 19 is fixedly installed on the inner side of the groove 10. When the plug 5 is inserted into the slot 8 and fits with the limiting piece 19, the positioning hole 7 on the surface of the connecting post 6 corresponds to the limiting rod 18. The fixed setting of the limiting piece 19 can accurately limit the insertion depth of the lamp body 1 when the plug 5 is inserted into the slot 8 and fits with the limiting piece 19, ensuring that the positioning hole 7 on the surface of the connecting post 6 is completely aligned with the axis of the limiting rod 18. Automatic alignment is achieved during the installation process through physical limiting, avoiding the limiting rod 18 from not being accurately embedded in the positioning hole 7 due to incomplete insertion, without the need for repeated manual adjustment of alignment.

[0032] When the worm gear 9 rotates clockwise, the drive rod 15 drives the I-shaped slider 17 to gradually approach the connecting post 6 along the slide groove 16. When the worm gear 9 rotates counterclockwise, the drive rod 15 drives the I-shaped slider 17 to move away from the connecting post 6 along the slide groove 16. Through the clockwise or counterclockwise rotation of the worm gear 9, the inner wall of its surface arc groove 14 generates a radial thrust on the drive rod 15, causing the I-shaped slider 17 to slide back and forth along the slide groove 16. When rotating clockwise, the drive rod 15 pushes the I-shaped slider 17 to insert the limiting rod 18 into the positioning hole 7 of the connecting post 6, realizing the mechanical locking between the lamp body 1 and the mounting bracket 3. When rotating counterclockwise, the drive rod 15 drives the I-shaped slider 17 to disengage the limiting rod 18 from the positioning hole 7, releasing the locked state.

[0033] A solar panel 2 is fixedly installed on the top of the lamp body 1. The mounting bracket 3 has mounting holes 4 at each of its four corners. Screws can be installed inside the mounting holes 4 to fix the mounting bracket 3 in a designated position. By designing the mounting bracket 3 and the lamp body 1 as a detachable plug-in structure, after the mounting bracket 3 is fixed to the wall through the four corner mounting holes 4, the lamp body 1 can be quickly positioned by the cooperation of the plug 5 and the slot 8. Combined with the locking mechanism of the limit plug 18 driven by the worm gear 9 and worm 11, the lamp body 1 forms a stable mechanical connection after installation. After the mounting bracket 3 is fixed to the wall once, there is no need to repeat the operation on the wall fixing structure when maintaining or replacing the lamp body 1. The lamp body 1 can be disassembled and installed by simply turning the knob 13. This solves the problem that it is difficult to disassemble and maintain the lamp after it is fixed to the wall in the prior art. At the same time, it reduces the risk of repeated damage to the wall structure and improves the maintainability of the product and the flexibility of the installation position.

[0034] A fixing plate 21 is fixedly installed on one side of the bottom of the mounting bracket 3. A locking block 20 is fixedly installed on the surface of the telescopic rod 12. A through hole 22 is opened on the surface of the fixing plate 21. Multiple slots 23 are evenly opened on the side wall of the through hole 22. The locking block 20 and the slots 23 fit together. Through the limiting and locking structure of the fixing plate 21, the locking block 20 and the slots 23, when it is necessary to adjust the rotation of the worm gear 11, the external force pushes the telescopic rod 12 to drive the locking block 20 to slide along the through hole 22 of the fixing plate 21. At this time, the locking block 20 disengages from the original slot 23. Then, the knob 13 can be rotated to rotate the worm gear 11. The slot 23 limits the circumferential movement of the locking block 20, preventing the worm gear 11 from rotating due to vibration or external force, ensuring that the worm wheel 9 and the worm gear 11 transmission system remain stationary in the locked state, and preventing the limiting rod 18 from disengaging from the positioning hole 7 due to the movement of the worm gear 11.

[0035] Working principle: In actual use, first fix the mounting bracket 3 to the wall or other installation position with screws through the mounting holes 4 at the four corners. When installing the lamp body 1, align the insert 5 on the back of the lamp body 1 with the slot 8 of the mounting bracket 3 and insert it. Push the lamp body 1 until the insert 5 fits with the limiting piece 19 in the groove 10. At this time, the positioning hole 7 on the surface of the connecting column 6 is precisely aligned with the limiting insert 18.

[0036] Then, turn the knob 13. The knob 13 drives the telescopic rod 12 to rotate the worm 11. The worm 11 meshes with the worm wheel 9 and drives the worm wheel 9 to rotate. The inner wall of the arc groove 14 on the surface of the worm wheel 9 generates a radial thrust on the drive rod 15, forcing the drive rod 15 to drive the I-shaped slider 17 to slide along the slide groove 16 towards the connecting column 6, thereby pushing the limiting rod 18 into the positioning hole 7. When the worm 11 rotates to the position, pull the telescopic rod 12 outward, causing the locking block 20 to engage with the slot 23 in the through hole 22, thereby limiting the telescopic rod 12. The self-locking characteristics of the worm wheel 9 and the worm 11 are used to complete the firm locking of the lamp body 1 and the mounting bracket 3.

[0037] During disassembly, turn the knob 13 in the opposite direction, and the worm gear 9 will rotate counterclockwise. The arc groove 14 will drive the I-shaped slider 17 to move in the opposite direction through the drive rod 15, so that the limit plug 18 will disengage from the positioning hole 7. After the locking state is released, the lamp body 1 can be directly pulled out from the slot 8.

[0038] Throughout the process, the meshing transmission of the worm gear 9 and worm 11, along with the trajectory guidance of the arc groove 14, form a linkage mechanism that drives multiple sets of limit rods 18 to move synchronously. Installation or disassembly can be achieved by operating the knob 13 with only one hand, without the need for tools such as wrenches. This avoids the tedious process of repeatedly tightening traditional bolts. At the same time, the mechanical self-locking of the worm gear 9 and worm 11 ensures connection stability, significantly improving the efficiency of solar wall lamp installation and disassembly and the convenience of maintenance, while reducing the risk of component damage.
