Description

Technical Field

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

[0002] Flammable and explosive environments are extremely common in many fields such as industrial production, mining, and petrochemicals. Taking the petrochemical industry as an example, in the refining, ethylene production, and oil and gas storage and transportation processes, a large number of flammable and explosive chemicals such as alkanes and olefins are involved. If not handled carefully, they may cause violent explosions when exposed to a source of ignition. In mining, coal mines often have high concentrations of methane gas, and metal mining may also generate flammable and explosive dust. The working environment is full of risks. In these dangerous scenarios, explosion-proof lighting is a key lighting device to ensure operational safety, and its importance is self-evident.

[0003] In the design of existing explosion-proof lighting fixtures, the connection between the lamp cover and the lamp body is mostly achieved by bolting or welding. During routine maintenance, repair, or replacement of bulbs and lamp covers, workers need to use professional tools such as screwdrivers and wrenches. The operation process is cumbersome and consumes a lot of time and energy. Especially in special working environments such as high altitudes and confined spaces, using tools for disassembly and assembly is not only difficult, but may also cause tools to fall due to inconvenience, leading to safety accidents. Utility Model Content

[0004] To address this issue, this utility model provides an explosion-proof lighting lamp. By using a connecting component, it solves the problem that the connection between the lamp cover and the lamp body is often achieved through bolt fastening, welding, or other methods. This results in a cumbersome operation process where workers need to use professional tools such as screwdrivers and wrenches during daily maintenance, repair, or replacement of bulbs and lamp covers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof lighting lamp, comprising an explosion-proof lighting lamp body, a lampshade assembly at the bottom of the explosion-proof lighting lamp body, a connecting assembly between the explosion-proof lighting lamp body and the lampshade assembly, the lampshade assembly including a lampshade, a lampshade connecting seat fixedly provided at the top of the lampshade, multiple limiting holes opened on the outside of the lampshade connecting seat, the connecting assembly including a connecting frame unit, a connection status control block at the bottom of the connecting frame unit, a turntable unit inside the connecting frame unit, and multiple elastic reset components and connecting block components at the top of the turntable unit.

[0006] Preferably, the connecting frame unit includes a connecting frame, the bottom of the connecting frame is provided with an obstacle avoidance groove, a plurality of connecting block limiting grooves are fixedly provided inside the connecting frame, and a plurality of connecting block sliding grooves are provided on the inner side of the connecting frame.

[0007] Preferably, the top of the connection status control block extends through the obstacle avoidance groove and is slidably connected to the obstacle avoidance groove, and the top of the connection status control block extends into the interior of the connection frame.

[0008] Preferably, the turntable unit includes a turntable, which is disposed inside the connecting frame and slidably connected to the connecting frame. The bottom of the turntable is fixedly connected to the top of the connection status control block. The top of the turntable is disposed at the bottom of multiple connecting block limiting grooves and slidably connected to the bottom of multiple connecting block limiting grooves. Multiple inclined grooves are opened inside the turntable.

[0009] Preferably, the elastic reset component includes a turntable fixing block, a spring, and a connecting frame fixing block. The turntable fixing block is fixedly connected to the turntable, and the two ends of the spring are fixedly connected to the turntable fixing block and the connecting frame fixing block, respectively. The connecting frame fixing block is fixedly connected to the inner wall of the connecting frame.

[0010] Preferably, the connecting block assembly includes a sloping groove slide column, the top of which is fixedly provided with a lower abutment block for the lampshade connecting seat, and the top of the lower abutment block for the lampshade connecting seat is fixedly provided with a limiting port insertion block.

[0011] Preferably, the inclined groove slide column passes through the inclined groove and is slidably connected to the inclined groove.

[0012] Preferably, the lower abutment block of the lampshade connecting seat and the limiting port insertion block both pass through the connecting block groove and are slidably connected to the connecting block groove.

Detailed Implementation

[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] See attached document Figure 1 -Appendix Figure 8 The present invention provides an explosion-proof lighting lamp, including an explosion-proof lighting lamp body 10, a lampshade assembly 20 at the bottom of the explosion-proof lighting lamp body 10, a connecting assembly 30 between the explosion-proof lighting lamp body 10 and the lampshade assembly 20, the lampshade assembly 20 including a lampshade 21, a lampshade connecting seat 22 fixedly provided at the top of the lampshade 21, a plurality of limiting holes 23 opened on the outside of the lampshade connecting seat 22, the connecting assembly 30 including a connecting frame unit 31, a connection status control block 32 at the bottom of the connecting frame unit 31, a turntable unit 33 inside the connecting frame unit 31, and a plurality of elastic reset components 34 and a connecting block assembly 35 at the top of the turntable unit 33;

[0029] In this embodiment, to achieve tool-free quick assembly and disassembly of 20, the mechanical structure linkage design of the connecting component 30 utilizes the connection state control block 32 to drive the turntable unit 33 to rotate. With the cooperation of the inclined groove 332 and the inclined groove slide 351, the rotational motion of the turntable 331 is converted into radial displacement of the connecting block assembly 35, causing the limiting port insertion block 353 and the limiting port 23 to form a plug-in locking structure. The spring 342 in the elastic reset assembly 34 accumulates potential energy when the turntable 331 rotates, and automatically drives the turntable to reset after the control block is released, thus realizing the connection block... The automatic extension and locking of the components allows for the assembly and disassembly of the lampshade assembly 20 and the explosion-proof lighting body 10 without tools. At the same time, the sealing surface design of the connecting frame unit 31 and the lampshade connecting seat 22 meets the explosion-proof standard, ensuring safe use in flammable and explosive environments. In the resting state, the spring 342 continuously provides the contraction tension (a damped spring structure can also be used to ensure that the spring will not shake when no external force is applied), ensuring that the limit port plug 353 is always in the limit port 23 under natural conditions, and ensuring that the lampshade assembly 20 is always in a normal connection state under natural conditions.

[0030] To achieve stable operation and precise guidance of the connecting component 30, the device employs the following technical solution: the connecting frame unit 31 includes a connecting frame 311, with an obstacle avoidance groove 312 at the bottom of the connecting frame 311. Multiple connecting block limiting grooves 313 are fixedly arranged inside the connecting frame 311, and multiple connecting block sliding grooves 314 are opened on the inner side of the connecting frame 311. The obstacle avoidance groove 312 is a connecting... The vertical sliding of the connection status control block 32 provides guidance and clearance space to avoid interference with the connecting frame 311 during its movement; multiple connecting block limiting grooves 313 can axially limit the turntable 331 to ensure that the turntable 331 remains stable during rotation and does not move up and down; while the connecting block slide groove 314 provides a radial sliding track for the lamp cover connecting seat lower abutment block 352 and the limiting port insertion block 353 in the connecting block assembly 35, so that the two can be accurately inserted into or pulled out of the lamp cover connecting seat 22 along the slide groove under the drive of the inclined slide column 351, realizing reliable connection and quick separation between the lamp cover assembly 20 and the explosion-proof lighting body 10;

[0031] To achieve the tool-free rotation and automatic reset of the turntable 331, the device employs the following technical solution: the top of the connection state control block 32 penetrates the obstacle avoidance groove 312 and is slidably connected to it; the top of the connection state control block 32 extends into the connection frame 311; the turntable unit 33 includes a turntable 331, which is located inside the connection frame 311 and slidably connected to it; the bottom of the turntable 331 is fixedly connected to the top of the connection state control block 32; the top of the turntable 331 is located at the bottom of multiple connection block limiting grooves 313 and slidably connected to them; multiple inclined grooves 332 are provided inside the turntable 331; and the elastic reset assembly 34 includes the turntable. The assembly includes a fixing block 341, a spring 342, and a connecting frame fixing block 343. The turntable fixing block 341 is fixedly connected to the turntable 331. The two ends of the spring 342 are fixedly connected to the turntable fixing block 341 and the connecting frame fixing block 343, respectively. The connecting frame fixing block 343 is fixedly connected to the inner wall of the connecting frame 311. The connecting block assembly 35 includes a sloping groove slide column 351. A lampshade connecting seat lower abutment 352 is fixedly provided on the top of the sloping groove slide column 351. A limiting port insertion block 353 is fixedly provided on the top of the lampshade connecting seat lower abutment 352. The sloping groove slide column 351 passes through the sloping groove 332 and is slidably connected to the sloping groove 332. The lampshade connecting seat lower abutment 352 and the limiting port insertion block 353 both pass through the connecting block slide groove 314 and are slidably connected to the connecting block slide groove 314. Next, one end of the lower abutment block 352 of the lampshade connecting seat extends into the bottom of the lampshade connecting seat 22 and slides into the bottom of the lampshade connecting seat 22. One end of the limiting port insertion block 353 extends into the limiting port 23 and slides into the limiting port 23. The top of the connection status control block 32 passes through the obstacle avoidance groove 312 and slides into the obstacle avoidance groove 312. Its top extends into the connection frame 311 and is fixedly connected to the turntable 331, forming a power input end for manual operation. The operator can directly rotate the connection status control block 32 to drive the turntable 331 to rotate synchronously within the connection frame 311. The top of the turntable 331 slides into the bottom of the limiting groove 313 of the connecting block to ensure axial stability during rotation. The inclined groove 332 inside the turntable 331 and the elastic The reset assembly 34 forms a linkage mechanism: when the turntable 331 rotates clockwise, the turntable fixing block 341 moves synchronously with the turntable, stretching the spring 342 to accumulate elastic potential energy; at this time, the inclined groove 332 pushes the inclined groove slide column 351 to retract radially, realizing the unlocking of the lampshade assembly. When the operator releases the connection status control block 32, the spring 342 releases potential energy to drive the turntable fixing block 341 to move in the opposite direction, causing the turntable 331 to reset counterclockwise. The inclined groove 332 simultaneously pushes the connecting block assembly 35 to extend radially, completing the automatic locking of the lampshade. This structure converts the spring potential energy into the rotation power of the turntable, realizing the "rotation unlocking - release reset" cycle operation without additional tools, meeting the safety and convenience maintenance needs in explosion-proof environments.

[0032] The usage process of this utility model is as follows: When using this utility model, if it is necessary to disassemble the lampshade assembly 20 for maintenance or replacement, rotate the connection status control block 32 clockwise. The connection status control block 32 drives the turntable 331 to rotate clockwise. The inclined groove 332 inside the turntable 331 cooperates with the inclined groove slide column 351 in the connection block assembly 35. When the turntable 331 rotates, the inclined groove 332 squeezes and pushes the inclined groove slide column 351 to slide along the inclined groove 332. Since the top of the inclined groove slide column 351 is fixedly provided with the lampshade connecting seat lower abutment block 352 and the limiting port insertion block 353, and both of them pass through the connecting block slide groove 314 and are slidably connected to the connecting block slide groove 314, the sliding of the inclined groove slide column 351 drives the lampshade connecting seat lower abutment block 352 to be pulled out from the bottom of the lampshade connecting seat 22, and the limiting port insertion block 353 to be pulled out from the limiting port 23, thereby disconnecting the lampshade assembly 20 from the explosion-proof lighting body 10, making it convenient for the operator to remove the lampshade assembly 20 from the explosion-proof lighting body. Remove the lampshade assembly 20 from point 10. Simultaneously, as the turntable 331 rotates, it stretches the spring 342 via the turntable fixing block 341, causing the spring 342 to extend and accumulate elastic potential energy, providing power for subsequent reset operations. When maintenance or replacement is complete and the lampshade assembly 20 needs to be reinstalled, first align the lampshade assembly 20 with the explosion-proof lighting body 10, so that the lampshade connecting seat 22 is initially aligned with the connecting frame unit 31. At this point, release the connection status control block 32, and the spring 342 extends... The accumulated elastic potential energy causes the turntable 331 to rotate counterclockwise and reset. The inclined groove 332 squeezes and pushes the inclined groove slide column 351 to slide and reset, causing the lower abutment block 352 and the limiting port insertion block 353 of the lamp cover connecting seat to extend outward. The limiting port insertion block 353 is inserted into the limiting port 23 outside the lamp cover connecting seat 22, and the lower abutment block 352 of the lamp cover connecting seat presses against the bottom of the lamp cover connecting seat 22, realizing a stable connection between the lamp cover assembly 20 and the explosion-proof lighting body 10, and completing the entire installation process.
