Description

Technical Field

[0001] This utility model relates to the field of explosion-proof lighting technology, and in particular to an explosion-proof LED lighting lamp. Background Technology

[0002] As a core lighting device in hazardous environments, explosion-proof LED lighting not only needs to meet explosion-proof standards such as GB3836 to ensure no spark leakage in flammable and explosive gas and dust environments, but also needs to be adaptable to the lighting needs of different scenarios, while taking into account the convenience of installation and maintenance.

[0003] Regarding the aforementioned and existing related technologies, the inventors believe that the following shortcomings often exist: Traditional explosion-proof LED lights are mostly fixed-angle installation structures, or can only achieve limited angle adjustment by removing bolts and replacing shims, which is cumbersome and time-consuming. Due to the complexity of hazardous working environments, lighting needs to achieve multi-angle and precise illumination, but existing devices lack flexible angle adjustment and locking mechanisms, and cannot quickly adapt to different lighting needs; some adjustable structures lack clear limit designs, resulting in low angle adjustment accuracy, easy illumination deviation, and affecting operational safety.

[0004] Installation and maintenance are inconvenient and pose high safety risks: Existing devices often feature an integrated design between the lamp body and mounting bracket. Adjusting the angle, replacing the lamp body, or performing maintenance requires complete disassembly of the mounting structure, resulting in complex procedures and high labor intensity. Especially in hazardous environments, prolonged maintenance work not only reduces efficiency but may also lead to safety accidents due to prolonged operator exposure or improper tool use. Furthermore, frequent disassembly can cause the mounting structure to loosen, further compromising explosion-proof performance. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the traditional device has the disadvantages of cumbersome angle adjustment and lack of precise limit in the existing technology. Therefore, we propose an explosion-proof LED lighting lamp.

[0006] To achieve the above objectives, this application adopts the following technical solution: an explosion-proof LED lighting lamp, comprising an explosion-proof lighting lamp body, with fixed rods fixedly connected to both sides of the explosion-proof lighting lamp body, a connecting plate rotatably connected to the arc surface of the fixed rod, a fixed plate fixedly connected to one side of the two connecting plates that are close to each other, a semi-circular plate fixedly connected to the surface of the connecting plate, a connecting rod slidably inserted into the semi-circular plate, a retaining plate fixedly connected to one end of the connecting rod, a plurality of retaining grooves formed on the arc surface of the fixed rod, the retaining plate slidably connected to the inner wall of the retaining grooves, a mounting plate fixedly connected to the other end of the connecting rod, a threaded rod threaded into the mounting plate, a washer fixedly connected to one end of the threaded rod, and one end of the washer abutting against the connecting plate.

[0007] Preferably, a spring is fitted onto the arc surface of the connecting rod, and the two ends of the spring are fixedly connected to the semi-circular plate and the mounting plate, respectively.

[0008] Preferably, one end of the lead screw is fixedly connected to an explosion-proof handle.

[0009] Preferably, a damping ring is fixedly connected to the arc surface of the fixing rod, and the damping ring is located below the connecting plate.

[0010] Preferably, a number of heat dissipation fins are fixedly connected to the arc surface of the explosion-proof lighting body.

[0011] Preferably, the surface of the fixing plate has two fixing holes, which are elliptical in shape.

[0012] Preferably, two friction pads are fixedly connected to the surface of the fixing plate.

[0013] The technical effects and advantages of this utility model are as follows: The fixed rod and the connecting plate are rotatably connected, which can drive the lamp body to rotate around the fixed rod, realize multi-angle lighting adjustment, and adapt to the lighting needs of different work scenarios; Several slots on the arc surface of the fixed rod cooperate with the card plate to realize precise angle limit.

[0020] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0021] Reference Figure 1-4 As shown, this utility model provides a technical solution: an explosion-proof LED lighting lamp, including an explosion-proof lighting lamp body 1, with fixed rods 2 fixedly connected to both sides of the explosion-proof lighting lamp body 1, a connecting plate 3 rotatably connected to the arc surface of the fixed rod 2, a fixed plate 4 fixedly connected to the side of the two connecting plates 3 that are close to each other, a semi-circular plate 5 fixedly connected to the surface of the connecting plate 3, a connecting rod 6 slidably inserted into the semi-circular plate 5, a clamping plate 7 fixedly connected to one end of the connecting rod 6, a plurality of clamping grooves 8 opened on the arc surface of the fixed rod 2, the clamping plate 7 slidably connected to the inner wall of the clamping grooves 8, and an installation plate 9 fixedly connected to the other end of the connecting rod 6, a threaded rod 10 inserted into the installation plate 9, a washer 11 fixedly connected to one end of the threaded rod 10, and one end of the washer 11 abutting against the connecting plate 3. The fixed rod 2 is rotatably connected to the connecting plate 3, which can drive the lamp body to rotate around the fixed rod 2 to achieve multi-angle lighting adjustment and adapt to the lighting needs of different work scenarios. Several slots 8 on the arc surface of the fixed rod 2 cooperate with the plate 7 to achieve precise angle limiting. After adjustment, the sliding connecting rod 6 makes the plate 7 embed into the slot 8, and then the screw 10 is rotated to push the pad 11 to press against the connecting plate 3, forming a double locking structure of mechanical limiting and friction pressing to ensure that the angle is firmly locked.

[0022] Reference Figure 3 As shown in this embodiment: a spring 12 is fitted onto the arc surface of the connecting rod 6, and the two ends of the spring 12 are fixedly connected to the semi-circular plate 5 and the mounting plate 9, respectively. When adjusting the lighting angle, pulling the mounting plate 9 causes the connecting rod 6 to move the locking plate 7 away from the locking groove 8 of the fixed rod 2. At this time, the spring 12 is stretched and generates elastic potential energy. When the angle is adjusted to the correct position, the mounting plate 9 is released, and the spring 12 retracts, which can automatically pull the connecting rod 6 and the locking plate 7 towards the locking groove 8, so that the locking plate 7 quickly embeds into the corresponding locking groove 8. There is no need for manual alignment, which greatly simplifies the angle locking operation steps. Especially when working at height or in confined spaces, it can improve operating efficiency and safety.

[0023] Reference Figure 3As shown in this embodiment, one end of the lead screw 10 is fixedly connected to an explosion-proof handle 13. The explosion-proof handle 13 is made of explosion-proof and anti-static material, and its connection structure with the lead screw 10 complies with the GB3836 explosion-proof standard. This can prevent sparks from being generated due to friction between the handle and the lead screw 10 during operation, completely eliminating ignition sources in hazardous environments and ensuring operational safety.

[0024] Reference Figure 3 As shown in this embodiment: a damping ring 14 is fixedly connected to the arc surface of the fixing rod 2, and the damping ring 14 is located below the connecting plate 3. The damping force of the damping ring 14 allows the connecting plate 3 to be temporarily positioned at any angle, so that the operator can adjust the lamp body angle without frequently locking the locking plate 7, making it easier to accurately find the best lighting position; for example, when repairing mine roadways, the lamp body angle can be fixed by the damping force for trial lighting, and the locking plate 7 can be locked after confirming that it is suitable, thus improving the angle adjustment accuracy and operational flexibility.

[0025] Reference Figure 3 As shown in this embodiment, a number of heat dissipation fins 15 are fixedly connected to the arc surface of the explosion-proof lighting body 1. The explosion-proof lighting body shell is constantly exposed to high temperatures, which may lead to aging of the shell material and failure of the sealant, affecting the explosion-proof performance. The heat dissipation fins 15 can reduce the temperature of the lighting body shell, avoid damage to the explosion-proof structure caused by high temperatures, maintain the long-term explosion-proof reliability of the device, and prevent safety accidents caused by high temperatures.

[0026] Reference Figure 2 As shown in this embodiment, the surface of the fixing plate 4 has two fixing holes 16, which are elliptical in shape. During actual installation, the pre-set mounting holes of the external structure may have positional deviations. The elliptical fixing holes 16 can provide lateral or longitudinal adjustment margins, allowing operators to fix the fixing plate 4 with bolts without re-drilling holes, greatly reducing the difficulty of installation. Especially when installing at heights or in complex environments, it can shorten the installation time and reduce operational risks.

[0027] Reference Figure 4 As shown in this embodiment, two friction pads 17 are fixedly connected to the surface of the fixing plate 4. The friction pads 17 are made of a high-friction coefficient anti-slip material. When in close contact with the external mounting surface, they can greatly increase the friction between the fixing plate 4 and the mounting surface, prevent the fixing plate 4 from sliding due to vibration, ensure the lamp body is installed stably, and avoid the lighting angle deviation.

[0028] Working principle: The operator attaches the fixing plate 4 to the external mounting surface, and according to the position of the preset mounting holes on the external structure, the bolts are passed through the elliptical fixing holes 16 on the surface of the fixing plate 4. If there is a positional deviation of the preset mounting holes, the elliptical fixing holes 16 can provide lateral or longitudinal adjustment margins, and the bolt position can be adjusted without re-drilling, which greatly reduces the difficulty of installation. Especially in high-altitude or complex and dangerous environments, it can shorten the installation time and reduce the risk of operation.

[0029] After the bolts are tightened, the two friction pads 17 on the surface of the fixing plate 4 are in close contact with the mounting surface. On the one hand, this increases the friction between the fixing plate 4 and the mounting surface, preventing the fixing plate 4 from sliding due to vibration. On the other hand, the elastic deformation of the friction pads 17 can absorb external vibration, reduce the impact of vibration on the bolt connection structure, prevent the bolts from loosening, and isolate the metal fixing plate 4 from the mounting surface to prevent the mounting surface from being scratched, ensuring the stable installation of the device and protecting the integrity of the mounting surface.

[0030] After installation, adjust the lighting angle of the lamp body according to the needs of the work scene to ensure accurate lighting adaptation. The operator holds the explosion-proof handle 13 at one end of the lead screw 10. It is made of explosion-proof and anti-static material and meets the GB3836 explosion-proof standard. Rotate the handle in the opposite direction to make the lead screw 10 rotate in the internal thread of the mounting plate 9, which will cause the washer 11 to disengage from the contact with the connecting plate 3 and release the friction pressure constraint. Then pull the mounting plate 9 to make the connecting rod 6 slide along the semi-circular plate 5, which will cause the clamping plate 7 to disengage from the groove 8 of the arc surface of the fixing rod 2. At this time, the spring 12 sleeved on the arc surface of the connecting rod 6 is stretched and generates elastic potential energy.

[0031] Multi-angle flexible adjustment and temporary positioning: Push the explosion-proof lighting body 1 to make the fixing rod 2 rotate around the connecting plate 3, thereby adjusting the lighting angle of the lamp body; during this process, the damping ring 14 on the arc surface of the fixing rod 2 (located below the connecting plate 3) contacts the bottom of the connecting plate 3 to generate damping force, which can make the connecting plate 3 temporarily positioned at any angle. The operator does not need to frequently lock the card plate 7, and can fix the lamp body angle for trial lighting by damping force, which is convenient to accurately find the lighting position that meets the work requirements, and improve the adjustment accuracy and operation flexibility.

[0032] After the angle is adjusted to the correct position, the lamp body angle is fixed by a double locking structure to ensure stable lighting. When the mounting plate 9 is released, the spring 12 stretched on the connecting rod 6 retracts, automatically pulling the connecting rod 6 and the locking plate 7 towards the fixing rod 2. This allows the locking plate 7 to be precisely embedded in the corresponding angle slot 8 of the fixing rod 2. The mechanical angle limit is achieved through the cooperation of the locking plate 7 and the slot 8, eliminating the need for manual alignment. This simplifies the operation process and improves efficiency and safety, especially when working at heights or in confined spaces.

[0033] Secondary locking by frictional compression: Rotate the explosion-proof handle 13 again, drive the lead screw 10 to move towards the connecting plate 3, push the pad 11 to abut tightly against the connecting plate 3, and increase the frictional force between the connecting plate 3 and the fixed rod 2 through the pressure of the pad 11, forming a double locking structure of mechanical limit and frictional compression; in this process, the explosion-proof handle 13 avoids the risk of tool use, and the explosion-proof material can prevent sparks from being generated during operation, completely eliminating the ignition source in the dangerous environment and ensuring the safety of the locking operation.

[0034] Once the angle is locked, the lamp can be started to illuminate. After the operation is completed, maintenance can be easily performed. Start the explosion-proof lighting body 1. The lamp body provides stable illumination under the action of the double locking structure. The damping ring 14 fills the tiny gaps, which can reduce the entry of flammable and explosive gases and dust into the device and improve the explosion-proof reliability. At the same time, the heat dissipation fins 15 on the arc surface of the lamp body quickly conduct the heat generated by the LED operation. By increasing the contact area, the heat dissipation is accelerated, the temperature of the lamp body shell is reduced, and the shell aging and sealant failure caused by high temperature are avoided. This maintains the long-term explosion-proof performance, prevents safety accidents, and extends the life of the LED beads.

[0035] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
