Description

Technical Field

[0001] This utility model relates to the field of detection technology, specifically a lantern for observing the flatness of indoor walls. Background Technology

[0002] When processing or producing certain items, the surface will not be perfectly flat. The difference between the unevenness and the absolute level is the flatness. Flatness testing is also required during wall decoration. One method is using work lights, but existing equipment cannot effectively dissipate heat from flatness observation lights that are used for extended periods, nor can it mount the lights on a bracket for easy sanding.

[0003] A wall flatness inspection work light disclosed in Chinese Utility Model Patent Application Publication No. CN211740148U has a support plate with a sliding connection to a pressure rod. A fixing frame is bolted to the bottom of the pressure rod, and a detection light is fixedly installed inside the fixing frame. A spring is sleeved on the middle of the surface of the pressure rod, and a pressure plate is bolted to the top of the spring. The hole at the center of the pressure plate is sleeved with the surface of the pressure rod. Rotary shafts are bolted to the front ends of both sides of the support plate, and movable wheels are sleeved on the ends of the rotating shafts away from the support plate. A connecting block is bolted to the rear side of the bottom of the support plate, and support wheels are rotatably connected to the bottom of both sides of the connecting block. However, during long-term observation, the internal LED light panel generates heat for an extended period without effective heat dissipation. Dust in the workplace enters the device through the air inlet during heat dissipation, significantly reducing the device's heat dissipation efficiency. Furthermore, if the strong light source cannot be blocked during observation, it may dazzle the eyes of the wall inspection personnel, greatly compromising the safety of their working environment. Therefore, we propose a novel device to solve these problems. Utility Model Content

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: It includes a lamp frame, an LED light panel inserted into one side of the lamp frame, a lampshade inserted into one side of the lamp frame, a rotating shaft seat provided on one side of the lamp frame, an upper light-expanding plate inserted into the upper surface of the lamp frame, a lower light-expanding plate inserted into the lower surface of the lamp frame, a fan plate provided on one side of the lamp frame, an adjusting handle inserted into one side of the fan plate, an air inlet opened on one side of the fan plate, a heat dissipation frame provided on one side of the fan plate, a fan provided on one side of the heat dissipation frame, a filter plate inserted inside the heat dissipation frame, and a cleaning wheel rotatably connected to one side of the heat dissipation frame.

[0008] Optionally, the LED light panel has heat dissipation scales on one side, the lower surface of the light frame has a lower heat dissipation hole, the upper surface of the lower heat dissipation hole is slidably connected to a movable plate, and the light frame has a heat dissipation vent on one side.

[0009] Optionally, a rotating rod is rotatably connected to one side of the rotating shaft seat, a connecting clamp is rotatably connected to one side of the rotating rod, and a light-blocking plate is threaded through one side of the connecting clamp.

[0010] Optionally, an upper prism plate is threaded through one side of the upper light-expanding plate, an upper light-expanding prism is inserted into one side of the upper prism plate, and the upper light-expanding plate is made of optical glass.

[0011] Optionally, a lower prism plate is threaded through one side of the lower light-expanding plate, and a lower light-expanding prism is inserted into one side of the lower prism plate. The material of the lower light-expanding plate is optical glass.

[0012] Optionally, a rotating shaft is provided on one side of the fan plate, a rotating shaft seat is rotatably connected to one end of the rotating shaft, a lantern box is provided on one side of the rotating shaft seat, a lantern handle is provided on the upper surface of the lantern box, a lantern switch is slidably connected to the upper surface of the lantern handle, a lantern battery is inserted into one side of the lantern box, and a power cover is inserted into one side of the lantern box.

[0013] Optionally, a connecting bracket is inserted into the lower surface of the lantern box, a fixed bracket is inserted into the lower surface of the connecting bracket, an auxiliary heat dissipation rod is provided on one side of the connecting bracket, and a movable plate is slidably connected to the upper surface of the auxiliary heat dissipation rod.

[0014] Optionally, a locking hole is provided on one side of the rotating shaft, and a locking bolt is inserted into one side of the locking hole. The rotating shaft seat is fixed to the rotating shaft by the locking bolt.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model has a reasonable structure. The wall inspection personnel can move the lamp by its handle, adjust the angle of the lamp frame by adjusting the handle, and use a lamp switch to illuminate the LED light panel to light the wall. An upper beam prism reflects the light beam onto an upper beam diffuser, which then diffuses the light source. A lower beam prism reflects the light beam onto a lower beam diffuser, which also diffuses the light source. A rotating light-blocking plate blocks the diffused light. The inspection lamp is placed on a connecting bracket, and the fixed bracket stabilizes the equipment above. This design effectively addresses the issue of strong light sources in wall flatness inspections. Ordinary inspection lamps, when used for flatness inspections, can easily dazzle workers' eyes if not blocked, potentially causing corneal burns, stinging, tearing, photophobia, and temporary blurred vision. In severe cases... This device can cause photokeratitis, greatly endangering the safety of the work environment for wall inspection personnel. It uses a light-blocking plate to block the diffused strong light, preventing it from shining into the eyes of the inspection personnel and significantly increasing their safety. The adjustable light frame allows for wall flatness observation. Previously, after observing wall flatness with a lantern, if secondary sanding was needed, the sander had to use the lantern, reducing convenience and efficiency. This device, mounted on a fixed bracket, illuminates the wall to assist the sander in secondary sanding. The upper and lower light-diffusing plates also diffuse the light source, ensuring complete coverage of the entire wall surface, greatly increasing convenience and efficiency.

[0017] 2. In this utility model, natural wind enters the equipment through the air inlet. A fan rotates to dissipate heat from the LED light panel. The fan also drives the cleaning wheel, and the auxiliary heat dissipation rod slides to move the movable plate. This achieves the desired effect when observing wall flatness. Because the LEDs emit strong light, they require heat dissipation. Conventional flatness observation lanterns only have one heat dissipation hole. Over prolonged use, a lantern with only one heat dissipation hole may experience internal combustion of the LED light panel, significantly reducing the equipment's lifespan and endangering the safety of personnel conducting the flatness observation. This equipment increases heat dissipation efficiency by opening multiple heat dissipation holes. The heat dissipation scales also guide the airflow from the fan to further increase heat dissipation. However, the working environment for flatness observation may contain a large amount of dust in the air. Dust drawn into the equipment may cause LED light panels to malfunction. Therefore, a filter plate is installed at the air inlet of this equipment. The filter plate can filter out the dust drawn in, preventing a large amount of dust from being drawn into the equipment. The cleaning wheel 13 can also clean the dust on the filter plate 12 by rotating it. If a large amount of dust adheres to the filter plate 12, it will lead to insufficient air intake and thus affect the heat dissipation efficiency. When the equipment is placed on a fixed bracket for flatness observation, it generally indicates that the equipment needs to work for a long time. Equipment that works for a long time requires higher heat dissipation efficiency. The auxiliary heat dissipation rod lifts the movable plate inside the light frame to expose the heat dissipation holes at the bottom to ensure better heat dissipation efficiency. When the staff lifts the light to observe the flatness, the heat dissipation holes at the bottom are closed to prevent hot air from blowing on the staff, which greatly increases the heat dissipation efficiency of the equipment and ensures the heat dissipation of the equipment when it works for a long time.

By placing the inspection lamp on the connecting bracket 30 and stabilizing the equipment above it with the fixing bracket 31, this device achieves a significant improvement in the safety of wall flatness inspection personnel. Unlike conventional inspection lamps, which emit strong light and can easily dazzle workers without obstruction, causing corneal burns, stinging, tearing, photophobia, and temporary blurred vision, and in severe cases, photokeratitis, this device uses a light-blocking plate 18 to block the diffused strong light, preventing it from shining into the eyes of inspection personnel and greatly increasing their safety. The adjustable lamp frame 1 is used for wall flatness inspection.After observing the flatness of a wall surface using a lantern, if a secondary grinding is needed, the grinding operator must use the lantern while grinding, which reduces the convenience and efficiency of the grinding work. This device, mounted on a fixed bracket 31, illuminates the wall surface to assist the grinding operator in secondary grinding. The upper and lower light diffusers 5 and 6 also diffuse the light source to ensure complete coverage of the entire wall surface, greatly increasing the convenience and efficiency of the grinding work.

[0029] like Figures 2 to 7As shown, in this embodiment, the light frame includes a lamp frame 1, an LED light board 2 inserted into one side of the lamp frame 1, a lampshade 3 inserted into one side of the lamp frame 1, a rotating shaft seat 4 provided on one side of the lamp frame 1, an upper light-expanding plate 5 inserted into the upper surface of the lamp frame 1, an upper prism plate 19 threaded through one side of the upper light-expanding plate 5, an upper light-expanding prism 20 inserted into one side of the upper prism plate 19, the upper light-expanding plate 5 being made of optical glass, a lower light-expanding plate 6 inserted into the lower surface of the lamp frame 1, a lower prism plate 21 threaded through one side of the lower light-expanding plate 6, a lower light-expanding prism 22 inserted into one side of the lower prism plate 21, the lower light-expanding plate 6 being made of optical glass, a fan plate 7 provided on one side of the lamp frame 1, a rotating shaft 23 provided on one side of the fan plate 7, and a locking hole provided on one side of the rotating shaft 23. A locking bolt is inserted into one side of the rotating shaft 23. The rotating shaft seat 24 is fixed to the rotating shaft 23 by the locking bolt. One end of the rotating shaft 23 is rotatably connected to the rotating shaft seat 24. A lantern box 25 is provided on one side of the rotating shaft seat 24. A connecting bracket 30 is inserted into the lower surface of the lantern box 25. A fixing bracket 31 is inserted into the lower surface of the connecting bracket 30. An auxiliary heat dissipation rod 32 is provided on one side of the connecting bracket 30. A moving plate 15 is slidably connected to the upper surface of the auxiliary heat dissipation rod 32. A lantern handle 26 is provided on the upper surface of the lantern box 25. A lantern switch 27 is slidably connected to the upper surface of the lantern handle 26. A lantern battery 28 is inserted into one side of the lantern box 25. A power cover 29 is inserted into one side of the lantern box 25. An adjustment handle 8 is inserted into one side of the fan plate 7. An air inlet 9 is provided on one side of the fan plate 7, a heat dissipation frame 10 is provided on one side of the fan plate 7, a fan 11 is provided on one side of the heat dissipation frame 10, a filter plate 12 is inserted inside the heat dissipation frame 10, a cleaning wheel 13 is rotatably connected to one side of the heat dissipation frame 10, a heat dissipation scale 14 is provided on one side of the LED light plate 2, a lower heat dissipation hole is provided on the lower surface of the light frame 1, a moving plate 15 is slidably connected to the upper surface of the lower heat dissipation hole, a heat dissipation air outlet is provided on one side of the light frame 1, a rotating rod 16 is rotatably connected to one side of the rotating shaft seat 4, a connecting clip 17 is rotatably connected to one side of the rotating rod, and a light-blocking plate 18 is threaded through one side of the connecting clip 17. During use, natural wind enters the equipment through the air inlet 9, and the fan 11 rotates to dissipate heat from the LED light plate 2. The fan 11 rotates, driving the cleaning wheel 13 to rotate. The auxiliary heat dissipation rod 32 slides, moving the movable plate 15. This achieves the desired effect during wall flatness observation. Because the LED emits a strong light source, heat dissipation is necessary. Typical flatness observation lanterns only have one heat dissipation hole. Over prolonged operation, the LED light panel 2 inside a lantern with only one heat dissipation hole is prone to internal combustion, significantly reducing the equipment's lifespan and endangering the safety of personnel conducting flatness observations. This device increases heat dissipation efficiency by opening multiple heat dissipation holes. The heat dissipation scale 14 also guides the airflow from the fan 11 to further increase heat dissipation efficiency. However, the working environment for flatness observation may contain a large amount of dust in the air.A large amount of dust drawn into the equipment may cause the LED light panel 2 to malfunction. Therefore, a filter plate 12 is installed at the air inlet of this equipment. The filter plate 12 can filter out the drawn-in dust, preventing a large amount of dust from being drawn into the equipment. The cleaning wheel 13 can also clean the dust on the filter plate 12 by rotating it. If a large amount of dust adheres to the filter plate 12, it will lead to insufficient air intake and affect the heat dissipation efficiency. When the equipment is placed on the fixed bracket 31 for flatness observation, it generally indicates that the equipment needs to work for a long time. Equipment that works for a long time requires higher heat dissipation efficiency. The auxiliary heat dissipation rod 32 lifts the movable plate 15 inside the light frame 1 to expose the heat dissipation holes at the bottom to ensure better heat dissipation efficiency. When the staff lifts the light for flatness observation, the heat dissipation holes at the bottom are closed to prevent hot air from blowing on the staff, which greatly increases the heat dissipation efficiency of the equipment and ensures the heat dissipation of the equipment during long-term operation.

[0030] The working principle of this practical application is as follows:

[0031] During use, the wall inspection personnel move the lamp by hand using the handle 26, adjust the angle of the lamp frame 2 by adjusting the handle 9, and illuminate the wall by turning on the LED light panel using the lamp switch 27. The light beam is reflected by the upper beam prism 20 to the upper beam 5, which diffuses the light source. The light beam is reflected by the lower beam prism 22 to the lower beam 6, which diffuses the light source. The diffused light is blocked by rotating the light-blocking plate 18. The inspection lamp is placed on the connecting bracket 30, and the equipment above is stabilized by the fixing bracket 31. Natural wind enters the equipment through the air inlet 9, and the fan 11 rotates to dissipate heat from the LED light panel 2. The fan 11 rotates to drive the cleaning wheel 13, and the moving plate 15 is moved by sliding the auxiliary heat dissipation rod 32.
