Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and more specifically to a camping lamp that can be hung and has a supporting structure. Background Technology

[0002] Camping lights are portable lighting tools designed specifically for outdoor activities. Their core function is to provide safe and reliable lighting for nighttime camping, hiking, or emergencies. They are also waterproof, shock-resistant, and have long battery life. Their uses include area lighting when setting up tents, ambient lighting for camping meals, supplemental lighting for reading inside tents, and emergency rescue signals in the wild, making them an indispensable piece of practical equipment for outdoor enthusiasts.

[0003] Currently, conventional camping lights are mainly designed as hanging lights. The core advantage of hanging camping lights is that they can be hung on the top of tents, tarps, or tree branches, avoiding taking up space. They also have a wide lighting coverage, achieving 360° unobstructed lighting. Chinese patent CN223063815U discloses a hanging camping light with a support structure, which includes a top cover and a light-transmitting lampshade connected to the bottom of the top cover. The top of the top cover has an outer bulge extending upward from the middle. The outer bulge has a hook step, which is connected to a rotatable hook, allowing it to be hung for use.

[0004] The aforementioned camping lights suffer from a technical defect due to their simple hanging design, which makes them unable to flexibly cope with complex environments. Without a suitable hanging point, they must be used in a resting state. However, due to the lack of a bottom support structure, they are often difficult to place stably, making them unusable as desktop light sources. This increases the limitations of usage scenarios, and users are forced to hold them by hand, which goes against the need for hands-free outdoor use. Utility Model Content

[0005] In response to the above issues, and to overcome the limitations of current suspended camping lights in adapting to complex environments, such as difficulty in using them in a stable, tabletop position when there is no suitable hanging point, thus restricting their use and forcing users to hold them by hand, which contradicts the need for hands-free outdoor use, this invention aims to provide a camping light that, by configuring an easily detachable lamp post and counterweight plate, can be used as a tabletop light source in a stable, tabletop position, thereby freeing the user's hands and making its use more versatile.

[0006] To achieve the above objectives, the technical solution of this utility model is:

[0007] A hanging camping light with a supporting structure includes a light body with a handle, a light pole, and a counterweight plate. The bottom of the light body has a mounting groove containing a mounting base. The mounting base has a mating hole at its bottom, and a connecting sleeve is provided within the mating hole. The inner wall of the connecting sleeve has a first internal thread. The light pole is a hollow tube structure with an opening at its lower end and a stud at its upper end. The stud is inserted into the connecting sleeve, and the first internal thread engages with the stud. The counterweight plate has a positioning hole corresponding to the interior of the light pole, and a first threaded fastener passes through the positioning hole and is inserted into the interior of the light pole. The inner wall of the light pole has a second internal thread, which engages with the first threaded fastener.

Detailed Implementation

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0033] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the purpose of simplifying the description and do not indicate or imply that the orientation is a specific orientation or specific orientation structure and operation. Therefore, they should not be construed as limiting this utility model.

[0034] like Figures 1 to 7As shown, a hanging camping light with a supporting structure includes a light body 1, a light pole 3, and a weight plate 4. The light body 1 has a handle 2, allowing it to be hung on the top of a tent, a tarp pole, or tree branches, avoiding space occupation and providing wide illumination coverage for unobstructed all-around lighting. The bottom of the light body 1 has a recessed mounting groove 101 containing a mounting base 5. The shape of the mounting base 5 matches the mounting groove 101, ensuring precise alignment and reducing installation and adjustment time. It also enhances vibration resistance and prevents the risk of the mounting base 5 loosening. The mounting base 5 has a mating hole 501 at its bottom, and a connecting sleeve 6 is provided inside the mating hole 501. Similarly, the shape of the connecting sleeve 6 is configured to match the shape of the mating hole 501 to achieve the same effect after the mounting groove 101 and the mounting base 5 are fitted together. In this utility model, one end of the connecting sleeve 6 is open and the other end is closed. The connecting sleeve 6 is inserted into the mating hole 501 and fixed to the mounting base 5 with its closed end, so that its open end communicates with the external space. The inner wall of the connecting sleeve 6 has a first internal thread 601. The lamp post 3 is a hollow tube structure. The lower end of the lamp post 3 is open, and a stud 301 is formed at the upper end. The stud 301 is inserted into the connecting sleeve 6. The internal thread 601 engages with the stud 301, allowing the lamp post 3 to be detachably fixed to the lamp body 1. A positioning hole 401 is provided on the counterweight plate 4, penetrating the upper and lower end faces of the counterweight plate 4 and corresponding to the internal space of the lamp post 3. A first threaded fastener 7 passes through the positioning hole 401. The first threaded fastener 7 can be a bolt, screw, etc., with no particular restrictions. The first threaded fastener 7 is simultaneously inserted into the interior of the lamp post 3 from the opening at the lower end of the lamp post 3. The inner wall of the lamp post 3 has a second internal thread 302, which engages with the first threaded fastener 7, fixing the counterweight plate 4 to the bottom of the lamp post 3. The counterweight plate 4 and the lamp post 3 serve as the support structure for the lamp body 1, allowing the lamp body 1 to be placed on the surface. The counterweight plate 4 provides stable support for the lamp body 1, enabling it to be used as a desktop light source. When there is no suitable hanging point, the user is not forced to hold it, thus freeing their hands. In addition, the lamp post 3 and the counterweight plate 4, which serve as the support structure, are detachable, thus avoiding obstruction when hanging. The lamp post 3, the lamp body 1, and the counterweight plate 4 are fixed by a threaded connection, and disassembly only requires a simple rotation, making disassembly simple and convenient. This allows users to adjust the connection between the lamp body 1 and the support structure according to the usage scenario.

[0035] like Figures 3 to 6As shown, a locking block 101a and an inner step 101b are formed sequentially from top to bottom on the side wall of the mounting groove 101. That is, the locking block 101a is located close to the inside of the mounting groove 101, and the inner step 101b is located close to the opening of the mounting groove 101. The mounting base 5 has a corresponding locking groove 502 and an outer step 503 on its side wall. The locking block 101a and the locking groove 502 engage with each other and form an interference fit, so that the mounting base 5 is tightly connected to the mounting groove 101. At the same time, the outer step 503 and the inner step 101b abut against each other to ensure that the mounting base 5 can be accurately installed in place.

[0036] like Figure 2 and Figure 7 As shown, multiple anti-slip pads 8 are arranged sequentially at the bottom of the counterweight plate 4. There is no particular limit to the number of anti-slip pads 8. The anti-slip pads 8 can be made of synthetic rubber, natural rubber, or other materials. When the counterweight plate 4 is placed on the placement surface, the anti-slip pads 8 come into contact with the placement surface and will deform under the pressure of the lamp body 1, lamp pole 3, and counterweight plate 4, thus adhering tightly to the placement surface and generating a large static friction force, which plays an anti-slip role and provides more stable support for the lamp body 1.

[0037] Furthermore, the counterweight plate 4 is made of metal, which has the characteristics of high strength, wear resistance and good stability. It can effectively increase the weight of the counterweight plate 4, so that the lamp body 1 can be stably supported and provide a more significant counterweight effect. The deformation resistance of metal can prevent the counterweight plate 4 from structural deformation caused by long-term pressure. At the same time, it has good rust prevention and corrosion resistance, which improves the applicability of this camping lamp in a variety of complex environments.

[0038] like Figure 1 As shown, there are two handles 2, which are staggered and each has one end hinged to the lamp body 1, while the other ends extend towards each other. Here, the end of the handle 2 hinged to the lamp body 1 is defined as the fixed end, and the other end as the free end. This allows the two handles 2 to be rotated independently to raise or lower. When both are rotated simultaneously towards each other and raised, the other ends of the two handles 2 will remain overlapping. When the camping lamp needs to be used in a suspended manner, one of the handles 2 is rotated first to raise it. At this time, an opening is formed between the free end of the handle 2 and the lamp body 1, allowing the top of the tent and the ceiling to be vented. The hanging support, such as a curtain pole or tree branch, is snapped in, and then the other handle 2 is rotated to lift it up. When the free ends of the two handles 2 overlap, they form a closed annular hanging cavity with the lamp body 1. In this way, the hanging support can be stably held in the hanging cavity, realizing the suspension of the lamp body 1. Based on the above settings, the shape of the hanging cavity formed between the two handles 2 and the lamp body 1 can be switched between open and closed. When the length of the hanging support is large, the complicated operation of inserting from the end and then sliding into place with the hanging support as a guide can be avoided, making the use of this utility model camping lamp hanging more convenient.

[0039] like Figure 11 As shown, the handle 2 consists of two parts: a hook 201 and a handle body 202. A rotating shaft 201a is formed on the hook 201, and a corresponding rotating hole 102 is provided on the lamp body 1. The rotating shaft 201a is inserted into the rotating hole 102 and is rotatably connected with the rotating hole 102. The cross-sectional shape of the handle body 202 is circular, that is, the handle body 202 adopts a cylindrical contour design. By reducing the curvature of the contact surface, the wear when rubbing against the suspended object is significantly reduced, thereby effectively improving the structural durability.

[0040] like Figures 8 to 10 As shown, the lamp body 1 includes a housing 1a and a light-transmitting cover 1b. A lamp plate 9, a battery 10, and a control circuit board 11 are disposed between the housing 1a and the light-transmitting cover 1b. A support groove 103 is formed on the top of the housing 1a. The support groove 103 is a recessed groove with a wire hole 103a inside, communicating with the space between the housing 1a and the light-transmitting cover 1b. A photovoltaic panel 12 is disposed within the support groove 103. A control switch 13 is disposed at the bottom of the light-transmitting cover 1b. It should also be noted that the mounting groove 101 is located at the center of the bottom of the light-transmitting cover 1b. The lamp plate 9, battery 10, and photovoltaic panel 12 are all electrically connected to the control circuit board 11. LED beads 901 are integrated on the lamp plate 9. The control switch 13 is a push-button switch. A pressure switch 13 is pressed onto a control circuit board 11, which integrates a chip. The control switch 13 sends control commands to the chip to control the on / off state of the LED beads 901 on the light board 9. When the LED beads 901 are lit, the beam of light emitted by them is projected into the external space through the light-transmitting cover 1b, providing lighting and ambiance for the user. The photovoltaic panel 12 converts solar energy into electrical energy, which is stored in the storage battery 10. The storage battery 10 powers the entire circuit, thus giving the camping light of this utility model the function of self-powered operation. This not only enhances the environmental protection attributes and reduces long-term use costs, but also meets the emergency needs of outdoor scenarios, effectively avoids battery anxiety, and significantly improves the adaptability for outdoor use.

[0041] like Figure 8 and Figure 9 As shown, the bottom of the light-transmitting cover 1b is also provided with a charging interface 14. The charging interface 14 is electrically connected to the control circuit board 11. In this utility model, the charging interface 14 is a type-c interface. A dust cover 15 is provided on the charging interface 14. The dust cover 15 is detachable from the lamp body 1. When the dust cover 15 is opened, the two ends of the power cord can be connected to the charging interface 14 and the external power supply to charge the battery 10. This provides users with a stable and reliable emergency power supply solution. The standardized Type-C interface has good compatibility and can significantly improve the convenience of charging.

[0042] like Figure 8 and Figure 9As shown, a power indicator light 16 is also provided at the bottom of the light-transmitting cover 1b. The power indicator light 16 is electrically connected to the control circuit board 11. The power indicator light 16 is used to reflect the energy storage status of the battery 10, so that users can intuitively determine whether the battery 10 needs to be charged.

[0043] like Figure 9 and Figure 10 As shown, an upper insertion tube 104 is formed at the bottom of the housing 1a, and a lower insertion tube 105 is formed at the top of the light-transmitting cover 1b. The upper insertion tube 104 is inserted into the lower insertion tube 105, and the lower insertion tube 105 communicates with the bottom of the light-transmitting cover 1b. A second threaded fastener 17 is inserted through the lower insertion tube 105. The second threaded fastener 17 can be a bolt, screw, etc., without special restrictions. The second threaded fastener 17 is inserted into the upper insertion tube 104, and the inner wall of the upper insertion tube 104 has a first threaded fastener 104. The third internal thread 104a is threaded into the second threaded fastener 17. That is to say, the housing 1a and the light-transmitting cover 1b are first connected by insertion, and then locked by the second threaded fastener 17. At the same time, the upper insertion tube 104 and the lower insertion tube 105 have multiple sets. Each set of upper insertion tube 104 and lower insertion tube 105 and the corresponding second threaded fastener 17 will form multiple positioning points between the housing 1a and the light-transmitting cover 1b, so as to achieve a stable connection between the two.

[0044] Combination Figures 1 to 11This utility model of a camping lamp supports both hanging and placement, allowing for more flexible use in complex environments. When there is no hanging point, the user can place the counterweight plate 4 on the placement surface. The counterweight plate 4 will provide stable support for the lamp body 1, allowing the lamp body 1 to be used as a desktop light source. This solves the problem of traditional camping lamps requiring the user to hold them, thus freeing the user's hands. When hanging is required, the first threaded fastener 7 connecting the lamp post 3 and the counterweight plate 4 can be rotated to engage with the second internal thread 302 inside the lamp post 3, separating the counterweight plate 4 from the lamp post 3. Then, the lamp post 3 can be rotated to disengage the upper stud 301 from the first internal thread 601 of the connecting sleeve 6. At this point, the lamp post 3 can be removed from the bottom of the lamp body 1 to avoid obstructing hanging. Then, one of the handles 2 can be rotated to lift it up. At this point, the free end of the handle 2 will form a... An opening is formed, through which the tent top, tarp pole, or tree branch can be clipped into the hanging support. After clipping, the other handle 2 is rotated to lift it up. When the free ends of the two handles 2 overlap, they form a closed annular hanging cavity with the lamp body 1. In this way, the hanging support can be stably held in the hanging cavity, realizing the suspension of the lamp body 1. After installation, the user can control the LED beads 901 on the lamp panel 9 to light up by pressing the control switch 13. When the LED beads 901 are lit, the beam of light emitted by them will be projected into the external space through the light-transmitting cover 1b to provide lighting and atmosphere for the user. The photovoltaic panel 12 converts solar energy into electrical energy and stores it through the storage battery 10. In addition, when the storage battery 10 is insufficient, the user can also open the dust cover 15 and connect the two ends of the power cord to the charging interface 14 and the external power source to charge the storage battery 10, providing the user with a stable and reliable emergency power supply solution.

[0045] The embodiments and descriptions above are merely illustrative of the principles and preferred embodiments of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
