Description

Technical Field

[0001] This utility model relates to the field of industrial and mining lamp technology, and in particular to an air damping device for LED industrial and mining lamps. Background Technology

[0002] Industrial and mining lamps refer to a general term for lighting fixtures used in production and operation areas of factories, mines, warehouses, and elevated structures. Some industrial and mining lamps are suitable for use in underground coal mines where there is a risk of gas and coal dust explosions, in the bottom mining area roadways, and in the construction roadways of mines with significant water seepage. Industrial and mining lamps can be divided into traditional light source industrial and mining lamps and LED industrial and mining lamps according to their light source. Compared with traditional industrial and mining lamps, LED industrial and mining lamps have gradually gained popularity due to their advantages such as directional light emission, low power consumption, good driving characteristics, fast response speed, high shock resistance, long service life, and environmental friendliness. Therefore, LED industrial and mining lamps have become the best choice for energy-saving lighting renovation in traditional large industrial plants. In addition to various lighting fixtures used in normal environments, LED industrial and mining lamps also include explosion-proof lamps and corrosion-resistant lamps used in special environments, and some industrial and mining lamps are used in large high-rise buildings. General lighting fixtures are usually evenly distributed above or on the side walls of the work area, illuminating the entire working surface.

[0003] Because the operating environment of LED high-speed and mining lamps differs from indoor environments, they often experience significant vibrations caused by mechanical operations. These vibrations can damage the internal light-emitting components of the LED high-speed and mining lamps, reducing their lifespan. Therefore, vibration damping is necessary to ensure their normal operation. However, existing vibration damping devices for LED high-speed and mining lamps mostly employ spring, rubber, or metal damping structures, which present the following problems: Firstly, rubber is prone to aging, and springs are susceptible to metal fatigue, requiring maintenance of the damping device. Existing damping devices, due to their sealed structure, require disassembly of the lamp housing for replacement, making maintenance difficult. Secondly, the spring, rubber, or metal damping structures in existing damping devices all use fixed damping coefficients, which cannot adapt to environments with varying vibration intensities, resulting in poor applicability of the damping devices. Utility Model Content

[0004] To address the technical problems of existing shock absorber devices being difficult to maintain and having poor applicability, this utility model provides the following technical solution.

[0005] This utility model discloses an air vibration damping device for LED industrial and mining lamps, comprising an upper connecting plate connected to a mounting base and a lower connecting plate connected to the LED industrial and mining lamp. The upper connecting plate is provided with mounting screw holes for connection to the mounting base, and the lower end of the lower connecting plate is provided with a lamp mounting end for connection to the LED industrial and mining lamp. The lower part of the upper connecting plate is fixedly provided with a plurality of connecting rods that are slidably connected to the lower connecting plate. The connecting rods are slidably connected to a plurality of movable plates. Both the upper and lower parts of the movable plates are connected to damping units. Each damping unit includes a plurality of airbags that abut against the movable plates and the upper connecting plate and a plurality of connecting pipes that connect adjacent airbags. One of the airbags is connected to an inflation valve.

[0006] As a further technical solution, an adjusting bolt is connected to one end of the connecting rod located on the lower connecting plate.

[0007] As a further technical solution, a damping ring sleeved on the outer periphery of the connecting rod is provided between the adjusting bolt and the lower connecting plate.

[0008] As a further technical solution, a sealing sleeve is provided between the upper connecting plate and the lower connecting plate, which is sleeved on the outside of the connecting rod and the shock absorption unit, and the inflation valve passes through the sealing sleeve.

[0009] As a further technical solution, the upper and lower parts of the movable plate are provided with positioning grooves that match the shape of the airbag.

[0010] As a further technical solution, a spare shock absorber is fitted around the outer periphery of the connecting pipe.

[0011] The beneficial effects of this utility model are as follows: The shock-absorbing device of this utility model has a movable shock-absorbing unit set between the upper and lower connecting plates. The shock-absorbing unit consists of multiple airbags connected in series. The airbags are filled with compressed air, and the air pressure of the airbags can be adjusted by the inflation valve, thereby controlling the shock-absorbing damping strength of the airbags. This allows the shock-absorbing unit to adapt to different vibration intensity environments. Furthermore, a damping ring is set between the lower connecting plate and the adjusting bolt, which can further adjust the damping coefficient of the shock-absorbing device, improving its adaptability. A spare shock-absorbing component is sleeved around the connecting pipe of the shock-absorbing unit. This allows for timely use of the spare shock-absorbing component in case of unit failure, ensuring the normal operation of the shock-absorbing device. Moreover, after opening the sealing sleeve, each shock-absorbing unit can be independently disassembled and replaced, and can be independently inflated and adjusted, without the need for complete disassembly of the LED industrial lamp. This makes the maintenance of the shock-absorbing device more convenient and easier to operate. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0017] In the description of this utility model, it should be understood that the terms "upper" and "lower" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0018] like Figure 1 As shown, this utility model discloses an air vibration damping device for LED industrial and mining lamps, comprising an upper connecting plate 1 connected to a mounting base and a lower connecting plate 2 connected to the LED industrial and mining lamp. The upper connecting plate 1 has multiple mounting screw holes 101 for connection to the mounting base, and the lower connecting plate 2 has a lamp mounting end 201 at its lower end for connection to the LED industrial and mining lamp. Therefore, the vibration damping device is an independently installed mechanism between the mounting base and the LED industrial and mining lamp, eliminating the need for complete disassembly of the LED industrial and mining lamp during maintenance, thus improving maintenance efficiency.

[0019] like Figure 2As shown, in a preferred embodiment, the lower part of the upper connecting plate 1 is fixedly provided with a plurality of connecting rods 3 that are slidably connected to the lower connecting plate 2. When the LED industrial and mining lamp vibrates and displaces, the lower connecting plate 2 can move longitudinally relative to the upper connecting plate 1. An adjusting bolt 10 is connected to one end of the connecting rod 3 located below the lower connecting plate 2. A damping ring 6 is provided between the adjusting bolt 10 and the lower connecting plate 2 and sleeved on the outer periphery of the connecting rod 3. The adjusting bolt 10 can be threaded upward or downward relative to the lower end of the connecting rod 3, thereby adjusting the compressive damping force of the damping ring 6, and thus fine-tuning the damping force of the shock absorption device.

[0020] The damping ring 6 can be a rubber ring, an airbag ring, or a rubber ring filled with damping fluid. When the LED industrial and mining lamp vibrates and shifts, the damping ring 6 is used to support the weight of the lower connecting plate 2 and the LED industrial and mining lamp, providing them with shock-absorbing damping force. The damping ring 6 is easy to replace, requiring only the removal of the adjusting bolt 10, making maintenance relatively convenient.

[0021] In a preferred embodiment, the connecting rod 3 is slidably connected to several movable plates 4. In this embodiment, there is only one movable plate 4, and each movable plate 4 has a sliding end 402 at its four corners. The sliding end 402 is slidably connected to the connecting rod 3 to ensure stable sliding of the movable plate 4 between the upper connecting plate 1 and the lower connecting plate 2. At this time, both the upper and lower parts of the movable plate 4 are connected to shock-absorbing units 5. The shock-absorbing unit 5 is an inflatable airbag structure, and the air pressure of the airbag can be adjusted by connecting an external air pump through the inflation valve 8, so that the shock-absorbing unit 5 can adapt to different vibration intensity environments, such as high-frequency vibration of mining equipment and low-frequency vibration of ordinary factories. With the addition of the damping ring 6 and the adjusting bolt 10, the vibration intensity can be finely adjusted, improving the applicability of the shock-absorbing device.

[0022] like Figure 3 As shown, in a preferred embodiment, there are two shock-absorbing units 5, one located below the movable plate 4 and the other above it. The shock-absorbing unit 5 located above the movable plate 4 includes several airbags 501 that abut against the movable plate 4 and the upper connecting plate 1. In this embodiment, there are nine airbags 501, evenly distributed on the upper part of the movable plate 4, providing a stable shock absorption effect on the same horizontal plane. Of course, the number of airbags 501 is not limited to nine; it can be fewer or more. Connecting pipes 502 connect adjacent airbags 501. The connecting pipes 502 have a hollow structure, allowing adjacent airbags 501 to be connected, ensuring that the air pressure inside all airbags 501 of the same shock-absorbing unit 5 is the same. One airbag 501 is connected to an inflation valve 8, which has the same structure as the valve in a conventional automobile tire, and its structure will not be described in detail. An air pump connected to the inflation valve 8 can be used to inflate or depressurize the airbags 501, allowing the shock-absorbing unit 5 to adapt to different vibration intensities.

[0023] In a preferred embodiment, the upper and lower parts of the movable plate 4 are provided with positioning grooves 401 that match the shape of the airbags 501. Meanwhile, the connecting end 502 is a rigid tube, allowing direct handholding to place all airbags 501 into the positioning grooves 401, stabilizing the airbags 501 between the movable plate 4 and the upper connecting plate 1 before inflation and pressurization. Simultaneously, a spare shock absorber 7, a rubber block, is fitted around the outer periphery of the connecting tube 502. The height of the spare shock absorber 7 is slightly lower than the height between the upper connecting plate 1 and the movable plate 4. When airbag 501 leaks air, the upper and lower parts of the spare shock absorber 7 respectively press against the upper connecting plate 1 and the movable plate 4, providing a backup shock absorption function. Meanwhile, in order to reduce the damage to the airbag 501 caused by the external environment and dust, a sealing sleeve 9 is provided between the upper connecting plate 1 and the lower connecting plate 2, which is sleeved on the outside of the connecting rod 3 and the shock absorption unit 5. The inflation valve 8 passes through the sealing sleeve 9. The sealing sleeve 9 is supported by a flexible material. When the shock absorption device needs to be maintained, the sealing sleeve 9 can be pulled open by force.

[0024] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
