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.

[0025] Example 1

[0026] Please see Figure 1 - Figure 5 Example 1 illustrates an explosion-proof fixed lamp, including a heat sink 1. A top cover 2 is fixedly connected to the opening at the top of the heat sink 1 by screws. A battery 3 and a controller 4 are fixedly installed at the bottom of the top cover 2 from left to right. Terminal blocks 5 are fixedly connected to the left and right sides of the bottom of the top cover 2. A connecting cylinder 6 is fixedly connected to the center of the top of the top of the top cover 2. A limiting sealing component 7 is embedded in the connecting cylinder 6. A light-emitting component 8 is fixedly connected to the center of the bottom of the heat sink 1 by thermally conductive silicone screws. A lampshade 9 is fixedly connected to the edge of the bottom of the heat sink 1 by screws. An installation adjustment component 10 is connected to the side wall of the heat sink 1.

[0027] The mounting and adjusting assembly 10 includes a fixing bracket 1001, an angle adjustment hole 1002, and a lamp fixing hole 1003. The two ends of the fixing bracket 1001 are matched and set in the grooves on the left and right side walls of the heat sink 1. Angle adjustment holes 1002 are provided at both ends of the fixing bracket 1001. The angle adjustment holes 1002 are used to fix the fixing bracket 1001 to the heat sink 1 by angle locking screws. A lamp fixing hole 1003 is provided at the top of the fixing bracket 1001.

[0028] Please see Figure 2 and Figure 4 The fixing bracket 1001 in the figure has an inverted U-shaped structure, and the angle adjustment hole 1002 adopts a semi-arc groove structure. The fixing bracket 1001 can be rotated and adjusted around the heat sink 1 through the angle adjustment hole 1002.

[0029] In this embodiment, the fixed lamp is securely connected to the desired lighting position using the lamp fixing hole 1003 on the top of the fixing bracket 1001. Both ends of the fixing bracket 1001 are connected to the heat sink 1 through the angle adjustment hole 1002 and the angle locking screw, allowing the user to adjust the angle of the light-emitting component 8 according to actual needs to achieve the optimal lighting effect. After adjustment, the angle is locked by the angle locking screw to prevent angle changes due to vibration or movement. This not only improves the flexibility of the lighting equipment but also enhances its adaptability in diverse working environments, ensuring stable operation of the lamp in hazardous environments.

[0030] Specifically, by installing the adjustment component 10, the explosion-proof fixed lamp can adjust the lighting angle according to actual needs to meet the lighting requirements of different occasions. The connecting cylinder 6 and the limiting sealing component 7 ensure the sealing and explosion-proof performance of the fixed lamp's wiring, ensuring safety when used in flammable and explosive environments. After installation, the lamp is powered by the storage battery 3, and the controller 4 controls the switching and brightness of the light-emitting component 8, ensuring stable operation of the lighting equipment in various complex environments. The heat sink 1 is responsible for dissipating the heat generated by the light-emitting component 8 during operation, thereby extending the lamp's service life and ensuring safe and stable operation even in high-temperature environments, providing good lighting effects, and possessing high safety and reliability, meeting the requirements for use in hazardous environments.

[0031] It should be noted that the heat sink 1 adopts a metal shell structure to ensure that the heat generated by the light-emitting component 8 can be quickly conducted and dissipated during long-term operation, thus extending the service life of the lamp. The lampshade 9 is made of glass, which is not only resistant to high temperatures but also has good impact resistance, further enhancing the lamp's protection capabilities in harsh environments. The heat sink 1 and the light-emitting component 8 are fixed with thermally conductive silicone and screws. In addition, the battery 3 and the controller 4 are also firmly connected to the heat sink 1 with screws, ensuring the stability of the lamp during operation. The connection points of the heat sink 1, the light-emitting component 8, and the lampshade 9 with the outside are all coated with sealant to enhance the lamp's sealing and explosion-proof performance.

[0032] Example 2

[0033] Please see Figure 2 and Figure 6 Example 2 is described below. This embodiment further describes Example 1. In the figure, the heat sink 1 is a cylindrical structure with an open top. The heat sink 1 is fitted with a battery 3 and a controller 4. The battery 3 and the controller 4 are fixedly connected to the heat sink 1 by screws. The controller 4 is electrically connected to the light-emitting component 8 by wires. The controller 4 is used to control the brightness and switching of the light-emitting component 8.

[0034] Furthermore, the light-emitting component 8 includes a lamp holder 801, an LED substrate 802, and LED lamp holders 803. The top of the lamp holder 801 is fixedly connected to the bottom of the heat sink 1, the bottom of the lamp holder 801 is fixedly connected to the LED substrate 802, and a plurality of LED lamp holders 803 are fixedly connected at equal intervals to the bottom of the LED substrate 802.

[0035] In this embodiment, the light-emitting component 8 can control the LED lamp holders 803 through the controller 4, thereby achieving the purpose of adjusting brightness and switching, improving luminous efficiency, reducing energy consumption, and ensuring the stability and lifespan of the light-emitting component 8. The equally spaced LED lamp holders 803 ensure uniform light distribution and provide uniform lighting effect. The cylindrical structure of the heat sink 1 helps to dissipate heat quickly, and the low heat generation characteristics of the LED lamp holders 803 further reduce the heat dissipation requirements, so that the entire explosion-proof fixed lamp maintains good performance during long-term operation.

[0036] It should be noted that the battery 3 and controller 4 are compactly integrated into the heat sink 1 and the top cover 2, making the entire explosion-proof fixed lamp small in size, easy to install and maintain. It can not only provide a stable power supply, but also realize intelligent power management through the controller 4, such as overcharge protection and over-discharge protection, to ensure the safe and reliable operation of the lamp. The wiring terminal 5 allows the power cord and control line of the lamp to be quickly connected and disconnected, which facilitates daily maintenance and inspection, improves the performance and maintenance convenience of the lamp, and is suitable for various flammable and explosive environments.

[0037] Example 3

[0038] Please see Figure 2 and Figure 7 Example 3 is described below. This embodiment further describes Example 2. The limiting sealing assembly 7 in the figure includes a clamping nut 701, a gasket 702 and a wire pass plug 703. The clamping nut 701 is fitted into the opening at the top of the connecting cylinder 6, and the gasket 702 is fitted into the opening at the bottom of the connecting cylinder 6. The wire pass plug 703 is provided between the clamping nut 701 and the gasket 702.

[0039] Furthermore, the bottom of the connecting cylinder 6 penetrates the upper cover 2 and communicates with its bottom cavity. The connecting wire inside the connecting cylinder 6 is limited and protected by the limiting sealing component 7 and connected to the terminal block 5.

[0040] In this embodiment, the gasket 702 and the wire guide plug 703 work together to ensure the sealing of the inside of the connecting cylinder 6 and prevent the infiltration of flammable and explosive gases. The clamping nut 701 is connected to the connecting cylinder 6 by threads. By rotating the clamping nut 701, the clamping force of the gasket 702 on the wire guide plug 703 can be adjusted, thereby achieving the sealing and fixing of the connecting wire and ensuring the stability and safety of the connection in harsh environments.

[0041] It should be noted that the use of the connecting cylinder 6 and the limiting sealing component 7 together ensures the sealing of the wiring part, effectively preventing the infiltration of dangerous gases in flammable and explosive environments, thereby greatly improving the safety of the lamp.
