[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] like Figures 1 to 5 The mobile explosion-proof lighting equipment shown includes: The bracket 1 includes a base frame 11 that contacts the ground, and a handle assembly 12 connected at one end to the base frame 11 and extending to one side of the base frame 11 at the other end. The handle assembly 12 is positioned parallel to the center of the plane containing the base frame 11, forming an accommodating space 13 between itself and the base frame 11. It should be noted that the base frame 11 can have various shapes, such as a rectangle, a triangle, a ring, or other feasible shapes. Specifically, to increase friction on the side of the base frame 11 that contacts the ground, an anti-slip structure can be provided, which can be made of rubber, a suction cup, or rivets, or other structures that provide anti-slip properties. Similarly, the extension direction of the handle assembly 12 can be vertical or angled, such as 30° or 45°, or other feasible angles. The handle assembly 12 can also be equipped with an anti-slip structure. The bracket 1 provides support and stability for the overall structure and also provides some protection for the internal structure of the accommodating space 13. In the bracket 1, the base frame and the handle assembly can be integrally formed, welded, connected by connectors, or other connection methods.

[0024] The support mechanism 2 is housed within the receiving space 13 and is fixedly connected to the bottom frame 11; The explosion-proof lighting mechanism 3, housed within the accommodating space 13, includes a main housing 31a rotatably connected to a support mechanism 2, a rear cover 31b connected to the main housing 31a, a light-emitting element 32 disposed inside the main housing 31a and the rear cover 31b, and a glass cover 33 disposed opposite to the light-emitting element 32 and fixed to the main housing 31a. The explosion-proof lighting mechanism 3 is housed within the accommodating space 13 and rotatably connected to the support mechanism 2, which provides support for the explosion-proof lighting mechanism 3. The rotatable connection allows the explosion-proof lighting mechanism 3 to be adjusted to different angles, achieving illumination at different angles and improving the overall portability of the equipment. Specifically, the explosion-proof lighting mechanism 3 is an explosion-proof structure, with an explosion-proof rating meeting national standards. The light-emitting element 32 is disposed inside the explosion-proof main housing 31a and the rear cover 31b. When internal components generate electric arcs, ignition, or high temperatures, the explosion-proof main housing 31a and the rear cover 31b can act as an isolation layer, preventing internal conditions from affecting the external environment or introducing gases and dust from the external environment.

[0025] The explosion-proof switch mechanism 4 is fixedly connected to the support mechanism 2 and connected to the light-emitting element 32. The explosion-proof rating of the explosion-proof switch mechanism 4 also meets the national explosion-proof rating. By limiting the contact surface of electrical components and the area where sparks are generated, it prevents direct contact between potentially explosive gases and electrical sparks or thermal effects. Specifically, the housing of the explosion-proof switch mechanism 4 can be made of high-strength explosion-proof materials, such as aluminum alloy or steel, which are not prone to generating sparks and have significant impact resistance and corrosion resistance.

[0026] The main housing 31a and the rear cover 31b, as well as the main housing 31a and the glass cover 33, are sealed together. Multiple bolt connections exist between the main housing 31a and the rear cover 31b. The glass cover 33 is bolted to the main housing 31a. Electronic components are installed between the main housing 31a and the rear cover 31b. The sealing connections between the main housing 31a and the rear cover 31b, and between the main housing 31a and the glass cover 33, can take many forms, including sealing rings, labyrinth seals, compression seals, or other sealing methods, or combinations of multiple sealing methods. Similarly, to ensure the explosion-proof effect between the main housing 31a and the rear cover 31b, and between the main housing 31a and the glass cover 33, bolt connections are also provided at the joints. Through these bolt connections and sealing connections, the explosion-proof lighting mechanism 3 achieves its explosion-proof rating. Similarly, the explosion-proof structure and explosion-proof form of the explosion-proof lighting mechanism 3 can be the form described above, or it can be a combination of other structures or forms added to the above forms, creating a highly reliable protective structure that enables the equipment to maintain excellent performance whether used indoors or in harsh outdoor environments.

[0027] This invention features a hollow base frame 11 that contacts the ground, reducing the contact area and improving adaptability to complex terrain, thus enhancing the stability of the equipment. A handle assembly 12, connected at one end to the base frame 11 and extending to one side of the frame, facilitates movement. The parallel alignment of the handle assembly 12 with the base frame 11 stabilizes the equipment's center of gravity. An internal storage space 13 is formed, within which a support mechanism 2 is fixedly connected to the base frame 11. The explosion-proof lighting mechanism 3 and switch are stably fixed to the support mechanism 2. The explosion-proof lighting mechanism 3 rotates on the support mechanism 2, allowing for more flexible light source direction. Furthermore, the light-emitting element 32, protected by a glass cover 33, effectively resists interference from the external environment, enhancing reliability and durability. The explosion-proof switch mechanism 4, directly connected to the light-emitting element 32, facilitates user operation and further improves usability. This invention optimizes the structure of the bracket 1, making the equipment both easy to carry and stable in various complex environments.

[0028] In existing designs of mobile explosion-proof lighting equipment base frames 11, a single-piece or irregular base structure is typically used. While this provides basic support, it is prone to instability during use, especially in complex outdoor environments where the equipment may tip over due to a small base contact area or an unstable center of gravity. For example... Figure 1 , Figure 2As shown, in some embodiments of this utility model, the base frame 11 is square, including a second side frame 11b and a fourth side frame 11d arranged parallel to each other, a third side frame 11c connected to the same end of the second side frame 11b and the fourth side frame 11d, and a first side frame 11a connected to the other end of the second side frame 11b. The handle assembly 12 is connected to the other end of the fourth side frame 11d. The square base frame 11 can effectively improve the stability of the base frame 11 in contact with the ground. Its four sides are evenly and evenly distributed, making the equipment more stable during use, especially in complex outdoor environments. Even if the equipment is subjected to external forces or uneven ground, it can ensure that the lighting equipment is supported and does not tip over. Compared with traditional single-piece bases or irregular base structures, the square base frame 11 improves stability, increases the contact area with the ground, and solves the problem of unstable center of gravity.

[0029] like Figure 3 As shown, in some embodiments of this utility model, the support mechanism 2 includes two opposing support plates 21, a fixed plate 22 connected to and fixedly connected to the support plates 21 on the first frame 11a and the third frame 11c, and an inclined brace 23 connected between the support plates 21 and the fixed plate 22, forming a triangular relationship with the support plates 21 and the fixed plate 22. The above structure effectively enhances the stability and pressure resistance of the support mechanism 2. The triangular mechanical structure can evenly distribute the external force on the equipment to each connection point, avoiding excessive single-point load-bearing pressure and improving the durability of the equipment. The inclined connection of the brace 23 further increases the deformation resistance of the entire support mechanism 2, ensuring structural stability even in complex environments or high-frequency usage scenarios.

[0030] like Figure 2 As shown, the handle assembly 12 includes a lifting rod 12a arranged parallel to the fourth frame 11d, and a connecting rod 12b connected to the other end of the fourth frame 11d. The connecting rod 12b is in the same plane as the first frame 11a and perpendicular to the plane of the bottom frame 11. The connecting rod 12b is located on the side of the support mechanism 2 away from the explosion-proof lighting mechanism 3. The handle assembly 12 and the bottom frame 11 are integrally formed. The position of the connecting rod 12b optimizes the mechanical balance between the handle assembly 12 and the equipment structure, making the position of the handle assembly 12 match the center of gravity of the equipment, effectively reducing the burden on the user when carrying the equipment. The integral forming eliminates the loosening problem that may exist in traditional connection methods, improves the stability and durability of the equipment, and can maintain structural integrity during long-term transportation or in harsh environments.

[0031] Continue to refer to Figure 2As shown, the connections between the first frame 11a and the second frame 11b, the second frame 11b and the third frame 11c, the third frame 11c and the fourth frame 11d, the fourth frame 11d and the connecting rod 12b, and the connecting rod 12b and the lifting rod 12a are all chamfered. Chamfering, by rounding the sharp edges at each connection, effectively reduces stress concentration in structural mechanics, allowing for a more even distribution of load at the connection. This significantly improves the impact resistance and structural durability of the entire device. Especially during long-term use or transportation, chamfering prevents damage caused by chipping or breaking at the connection, improving the overall stability of the device. Chamfering also offers significant advantages in terms of user experience. Rounded edges reduce the risk of bumps or scratches, ensuring safe use of the device, and preventing the edges from snagging on other items when carrying or transporting the equipment.

[0032] like Figure 2 As shown, there is a gap between the end of the first frame 11a away from the second frame 11b and the fourth frame 11d. Based on the above technical solution, the end of the bottom frame 11 of the one-piece molded bracket 1 does not need to be connected and fixed. On the one hand, it reduces the consumption of frame materials, enables the device to achieve a lightweight structural design, and further enhances portability. On the other hand, when storing the wire harness, it can pass through the gap and be wrapped between the fourth frame 11d and the lifting rod 12a.

[0033] Continue to refer to Figure 2 As shown, similar to the above technical solution, to reduce frame material consumption and achieve a lightweight structural design, the length of the lifting rod 12a is less than the distance between the two support plates 21. An anti-slip grip cover 12a1 made of rubber is provided on the lifting rod 12a. The anti-slip grip cover 12a1 on the surface of the lifting rod 12a, and the use of rubber for covering, further enhances the grip comfort and safety of the lifting rod 12a. Rubber material is soft, elastic, and has high friction, effectively preventing the device from slipping under both dry and wet conditions. The anti-slip treatment not only enhances the stability of the user's grip but also reduces hand fatigue during prolonged use.

[0034] like Figures 3 to 5The lighting mechanism 3 shown also includes a pressure ring 31c sealed to the other side of the main housing 31a. A glass cover 33 is fitted inside the pressure ring 31c and sealed to it. By securely fitting the glass cover 33 inside the pressure ring 31c and achieving a sealed connection, stable protection of the light source is ensured. This also effectively prevents external environmental factors such as dust and rain from damaging the light source and internal electronic components. Electronic components are rationally installed between the main housing 31a and the rear cover 31b, and the sealed connection at both ends provides multiple layers of protection for these components. The rational zoning of the electronic components makes the overall internal structure of the equipment more compact, while avoiding interference between the light source and electronic components, thereby improving the stability and efficiency of the equipment operation.

[0035] To improve user comfort, such as Figure 1 , Figure 3 As shown, the explosion-proof switch mechanism 4 is located on the side of the support plate 21 away from the main housing 31a. By detaching the switch from the main housing 31a and installing it at the far end of the support plate 21, the operating area of ​​the switch is made more independent and easily accessible. Users do not need to worry about the operation of the switch when adjusting the light source, and can quickly start or stop the equipment at any time. The switch is located away from the main housing 31a, reducing direct contact with the light source and electronic components. This not only avoids damage caused by the high temperature of the main housing 31a, but also provides a better operating environment for the switch, ensuring its reliability and durability under harsh conditions.

[0036] like Figure 2 As shown, multiple anti-slip pads 14 are provided on the side of the base frame 11 facing the ground. By integrating anti-slip pads 14 into the bottom, the equipment can maintain excellent stability in a variety of operating environments. The anti-slip pads 14 can be made of high-friction materials, such as rubber or polyurethane, providing good adhesion on dry or wet surfaces. The anti-slip pads 14 not only enhance the horizontal stability of the equipment, preventing slippage or displacement, but also mitigate vibration and impact when the equipment is placed on hard surfaces, thereby protecting the integrity of the base frame 11 and internal components and extending the service life of the equipment.
