Description

Technical Field

[0001] This utility model relates to the field of explosion-proof floodlight technology, and specifically discloses a vibration-resistant explosion-proof floodlight. Background Technology

[0002] In flammable and explosive environments such as industrial production, petrochemicals, and coal mining, explosion-proof floodlights are critical lighting equipment. Their safety, reliability, and durability directly affect the lighting quality and production safety of the working environment. However, existing explosion-proof floodlights still have many technical shortcomings in practical applications, making it difficult to meet the needs of complex working conditions.

[0003] Existing explosion-proof floodlights do not have dedicated anti-vibration components. In continuous vibration environments generated by equipment operation and blasting operations, the internal components of the lamp body are prone to loosening and poor contact due to resonance, and may even lead to fatigue damage of structural connectors, which seriously affects the service life of the equipment and the stability of the lighting.

[0004] In addition, the sealing structure often uses a single sealing ring design with a limited sealing contact area. Under long-term vibration, temperature changes or dust erosion, the seal is prone to failure, which can lead to rainwater, dust and other substances entering the lamp body. This not only affects the lighting effect, but may also cause short circuits due to moisture in electrical components, or even generate sparks, triggering an explosion risk.

[0005] Regarding locking mechanisms, existing products often use bolts for direct fastening. During frequent installation and maintenance, bolt-fastened structures are prone to bolt stripping or uneven stress on the sealing surface due to improper operation, affecting explosion-proof performance. Therefore, a vibration-resistant and explosion-proof floodlight is needed to solve these problems. Utility Model Content

[0006] This utility model proposes a vibration-resistant and explosion-proof floodlight. The double-sealed structure ensures the sealing reliability in complex environments and reduces safety hazards. The unique locking mechanism eliminates the need for bolts and achieves a stable connection through spring force and uniform distribution design, enhancing explosion-proof performance and overall stability. The vibration-resistant mechanism provides multi-directional and multi-frequency vibration protection.

[0007] This utility model is implemented as follows: a vibration-resistant and explosion-proof floodlight includes a floodlight body and a lamp cover. A sealing mechanism and four locking mechanisms are provided between the floodlight body and the lamp cover. A vibration-resistant mechanism is provided at the bottom of the floodlight body.

[0008] The sealing mechanism includes an annular groove formed at the upper end of the floodlight body, a support plate fixedly connected to the outer wall of the floodlight body, a groove formed at the upper end of the support plate, a first sealing ring adapted to the groove fixedly connected to the lower end of the lampshade, and a second sealing ring adapted to the annular groove fixedly connected to the top inside the lampshade.

[0009] The locking mechanism includes a column fixedly connected to the upper end of the floodlight body, an insertion hole through the outer wall of the column, a through hole through the upper end of the lampshade, a fixing plate fixedly connected to the upper end of the lampshade, an insertion rod through and slidably connected to the outer wall of the fixing plate, a movable plate fixedly connected to one end of the insertion rod, and a spring fixedly connected between the movable plate and the fixing plate.

[0010] The vibration damping mechanism includes a connecting plate fixed to the bottom of the floodlight body, a fixing seat below the connecting plate, four damping shock absorbers evenly distributed between the connecting plate and the fixing seat, an elastic mounting seat inside the floodlight body, the elastic mounting seat being connected to the inner wall of the floodlight body through circumferentially distributed buffer rubber columns, and the light source assembly being fixed in the middle of the elastic mounting seat.

[0011] As a preferred embodiment of the present invention, the other end of the plug rod is provided with a threaded hole, and an auxiliary plate is fixedly connected to the upper end of the lamp cover. The outer wall of the auxiliary plate is threaded through and threaded with a threaded rod.

[0012] As a preferred embodiment of the vibration-resistant and explosion-proof floodlight of this utility model, both the floodlight body and the lampshade are made of cast aluminum alloy and the surface is treated with high-voltage electrostatic powder coating.

[0013] In a preferred embodiment of this invention, the diameter of the socket is equal to the diameter of the plug rod.

[0014] In a preferred embodiment of this invention, the size of the through hole is equal to the size of the column.

[0015] As a preferred embodiment of the vibration-resistant and explosion-proof floodlight of this utility model, the middle part of the lampshade is made of transparent material.

[0016] The beneficial effects of this utility model are:

[0017] (1) In terms of sealing effect, the double sealing structure can effectively block rainwater, dust and other impurities from entering the lamp body, prevent electrical components from getting damp or contaminated with impurities, causing short circuits, sparks and other problems, ensuring the sealing reliability of the lamp in complex environments and reducing safety hazards.

[0018] (2) In terms of locking performance, the unique locking mechanism does not rely on bolts. It achieves a stable connection by driving the plug rod through the spring force. The four evenly distributed locking mechanisms can also ensure balanced force, avoiding problems such as stripping and uneven force that may occur when tightening bolts. It can maintain a stable state even in a vibration environment, further enhancing the explosion-proof performance and overall stability of the lamp.

[0019] (3) Four damping shock absorbers symmetrically distributed between the connecting plate and the fixed seat are used to efficiently absorb high-frequency vibrations by utilizing damping characteristics, blocking the direct transmission of energy to the floodlight body. The floodlight body is connected to the elastic mounting seat by circumferential buffer rubber columns. Through deformation, the low-frequency vibration energy is absorbed and converted into elastic potential energy for release, providing an independent buffer space for the core light source and realizing multi-directional and multi-frequency vibration protection.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0028] Please see Figure 1-5 A vibration-resistant and explosion-proof floodlight includes a floodlight body 1 and a lamp cover 2. A sealing mechanism and four locking mechanisms are provided between the floodlight body 1 and the lamp cover 2. A vibration-resistant mechanism is provided at the bottom of the floodlight body 1.

[0029] The sealing mechanism includes an annular groove 3 opened at the upper end of the floodlight body 1, a support plate 4 fixedly connected to the outer wall of the floodlight body 1, a groove 5 opened at the upper end of the support plate 4, a first sealing ring 6 adapted to the groove 5 fixedly connected to the lower end of the lamp cover 2, and a second sealing ring 7 adapted to the annular groove 3 fixedly connected to the top inside the lamp cover 2.

[0030] The locking mechanism includes a column 8 fixedly connected to the upper end of the floodlight body 1. The outer wall of the column 8 is provided with a through hole 17. The upper end of the lampshade 2 is provided with a through hole 16. The upper end of the lampshade 2 is fixedly connected to a fixing plate 9. The outer wall of the fixing plate 9 is slidably connected to a rod 12. One end of the rod 12 is fixedly connected to a movable plate 10. A spring 11 is fixedly connected between the movable plate 10 and the fixing plate 9.

[0031] The vibration damping mechanism includes a connecting plate 18 fixed to the bottom of the floodlight body 1, a fixing seat 19 below the connecting plate 18, four damping shock absorbers 20 evenly distributed between the connecting plate 18 and the fixing seat 19, an elastic mounting seat 22 is provided inside the floodlight body 1, the elastic mounting seat 22 is connected to the inner wall of the floodlight body 1 through circumferentially distributed buffer rubber columns 21, and the light source assembly is fixed in the middle of the elastic mounting seat 22.

[0032] In this embodiment: Regarding sealing, when the floodlight body 1 and the lampshade 2 are assembled, the first sealing ring 6 at the lower end of the lampshade 2 is embedded in the groove 5 at the upper end of the support plate 4, while the second sealing ring 7 at the top of the inside of the lampshade 2 is engaged in the annular groove 3 at the upper end of the floodlight body 1. This double sealing structure significantly increases the sealing contact area, effectively preventing rainwater, dust, and other external impurities from intruding into the lamp body, avoiding safety hazards such as short circuits and sparks caused by electrical components being damp or contaminated, and ensuring the sealing reliability of the lamp in complex environments.

[0033] For locking, during assembly, the through hole 16 of the lampshade 2 is aligned with the column 8 of the floodlight body 1 and inserted, so that the column 8 passes through the through hole 16. At this time, pulling the moving plate 10 will cause the insertion rod 12 to move away from the column 8, while the spring 11 is compressed. After releasing the moving plate 10, the restoring force of the spring 11 will push the insertion rod 12 through the fixing plate 9 and insert it into the insertion hole 17 of the column 8, thus achieving the initial locking of the lampshade 2 and the floodlight body 1. The four evenly distributed locking mechanisms work synchronously to ensure that the force between the lampshade 2 and the floodlight body 1 is balanced, avoiding the problem of poor sealing due to excessive local force. This structure does not rely on bolt fastening, reducing the possibility of stripping or uneven force due to improper operation. It can also maintain a stable locking state in a vibration environment, further enhancing the explosion-proof performance and overall stability of the lamp.

[0034] Four damping shock absorbers 20, connected between the connecting plate 18 and the fixed base 19, are symmetrically distributed to ensure balanced force distribution. They absorb high-frequency vibrations by utilizing damping characteristics, attenuating the amplitude and blocking direct transmission to the floodlight body 1. The elastic mounting base 22 inside the floodlight body 1 is connected to the inner wall through circumferential buffer rubber columns 21. The buffer rubber columns 21 absorb residual low-frequency vibrations through elastic deformation, converting energy into elastic potential energy and releasing it slowly. This provides an independent buffer space for the central light source assembly, avoiding rigid collisions. This dual function can adapt to multi-directional and multi-frequency vibrations, reducing the impact on the lamp body structure and core components, ensuring stable lighting and extending lifespan.

[0035] As a technical optimization of this utility model, the other end of the plug rod 12 is provided with a threaded hole 15, and the upper end of the lampshade 2 is fixedly connected to an auxiliary plate 14. The outer wall of the auxiliary plate 14 is threaded through and threadedly connected to a threaded rod 13.

[0036] In this embodiment: by rotating the threaded rod 13 on the auxiliary plate 14 to screw it into the threaded hole 15 of the plug rod 12, the movement of the plug rod 12 can be further restricted, preventing the plug rod 12 from accidentally dislodging from the plug hole 17 under conditions such as vibration and impact, thereby enhancing the stability of the locking mechanism and ensuring a more reliable connection between the lamp cover 2 and the floodlight body 1.

[0037] As a technical optimization of this utility model, both the floodlight body 1 and the lampshade 2 are made of cast aluminum alloy and their surfaces are treated with high-voltage electrostatic powder coating.

[0038] In this embodiment: the cast aluminum alloy material has high mechanical strength and impact resistance, which can provide solid structural support for the lamp and resist the influence of external forces such as collision and compression. At the same time, its low density can reduce the overall weight of the lamp and facilitate installation and transportation.

[0039] As a technical optimization of this utility model, the diameter of the socket 17 is equal to the diameter of the plug rod 12.

[0040] In this embodiment: when the plug rod 12 is inserted into the socket 17, the equal diameter allows the plug rod 12 to fully contact the inner wall of the socket 17, minimizing the gap and thus preventing the plug rod 12 from shaking or loosening inside the socket 17.

[0041] As a technical optimization of this utility model, the size of the through hole 16 is equal to the size of the column 8.

[0042] In this embodiment: when the lampshade 2 is assembled with the floodlight body 1, the column 8 passes through the through hole 16. The equal size allows the column 8 to fit tightly against the inner wall of the through hole 16, greatly reducing the gap and preventing the lampshade 2 from wobbling radially on the column 8.

[0043] As a technical optimization of this utility model, the middle part of the lampshade 2 is made of transparent material.

[0044] In this embodiment, the middle part of the lampshade 2 is made of transparent material, which can ensure that light can be transmitted efficiently and ensure the lighting effect of the floodlight.

[0045] The working principle and usage process of this utility model are as follows: Regarding sealing, when the floodlight body 1 and the lampshade 2 are assembled, the first sealing ring 6 at the lower end of the lampshade 2 is embedded in the groove 5 at the upper end of the support plate 4, while the second sealing ring 7 at the top of the interior of the lampshade 2 is engaged in the annular groove 3 at the upper end of the floodlight body 1. This double-sealing structure significantly increases the sealing contact area, effectively preventing rainwater, dust, and other external impurities from intruding into the lamp body, avoiding safety hazards such as short circuits and sparks caused by moisture or contamination of electrical components, and ensuring the sealing reliability of the lamp in complex environments.

[0046] For locking, during assembly, the through hole 16 of the lampshade 2 is aligned with the column 8 of the floodlight body 1 and inserted, so that the column 8 passes through the through hole 16. At this time, pulling the moving plate 10 will cause the insertion rod 12 to move away from the column 8, and the spring 11 will be compressed at the same time. After releasing the moving plate 10, the return force of the spring 11 will push the insertion rod 12 through the fixing plate 9 and insert it into the insertion hole 17 of the column 8, thus achieving the initial locking of the lampshade 2 and the floodlight body 1. By rotating the threaded rod 13 on the auxiliary plate 14, it is screwed into the threaded hole 15 of the insertion rod 12, which can further restrict the movement of the insertion rod 12 and prevent the insertion rod 12 from accidentally dislodging from the insertion hole 17 under conditions such as vibration and impact. The four evenly distributed locking mechanisms work synchronously to ensure that the force between the lampshade 2 and the floodlight body 1 is balanced, avoiding the problem of poor sealing surface due to excessive local force. This structure eliminates the need for bolt fastening, reducing the risk of stripping or uneven stress due to improper operation. It also maintains a stable locking state even under vibration, further enhancing the explosion-proof performance and overall stability of the lamp.

[0047] Four damping shock absorbers 20, connected between the connecting plate 18 and the fixed base 19, are symmetrically distributed to ensure balanced force distribution. They absorb high-frequency vibrations by utilizing damping characteristics, attenuating the amplitude and blocking direct transmission to the floodlight body 1. The elastic mounting base 22 inside the floodlight body 1 is connected to the inner wall through circumferential buffer rubber columns 21. The buffer rubber columns 21 absorb residual low-frequency vibrations through elastic deformation, converting energy into elastic potential energy and releasing it slowly. This provides an independent buffer space for the central light source assembly, avoiding rigid collisions. This dual function can adapt to multi-directional and multi-frequency vibrations, reducing the impact on the lamp body structure and core components, ensuring stable lighting and extending lifespan.
