Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting device technology, and in particular to a shock-resistant and wear-resistant work lamp. Background Technology
[0002] In shipbuilding, maintenance, and operation, cabin spraying operations (such as painting, sandblasting for rust removal, application of anti-corrosion coatings, spraying of cleaning agents, and fumigation for disinfection) are a common and critical process. These operations are usually carried out in environments with complex internal structures, enclosed spaces, and poor lighting, such as cargo holds, ballast tanks, fuel tanks, double bottoms, segregated compartments, and various piping passages.
[0003] To ensure worker safety (such as observing coating coverage, checking equipment status, identifying potential hazards, and locating safety exits) and work quality (such as checking coating uniformity and identifying missed areas), reliable, high-brightness portable lighting tools are indispensable. Work lights, due to their portability, flexibility, and relatively strong illumination capabilities, are among the most commonly used lighting devices for this type of work.
[0004] Existing work lights, when in use, present extremely harsh challenges due to the unique characteristics of shipboard spraying operations: Limited space and complex structure: Workers often need to climb, bend, or even crawl through narrow passages, steep ladders, and scaffolding, severely restricting their physical movement. Slippery and corrosive environment: The work area often contains oil stains, watermarks, and residual chemicals (such as solvents, rust removers, and paint), making the ground slippery. Vibration and impact: The operation of shipboard machinery, personnel movement, tool use, or even slight swaying of the ship itself can cause vibrations. Frequent collision risks: Workers must navigate through metal structures filled with protruding pipes, valves, supports, ribs, beams, and other protrusions, making collisions highly likely. In this harsh environment, workers carrying or holding work lights face a very high risk of accidental drops and impacts. Traditional work lights, especially those with casings made of ordinary plastic, lightweight aluminum alloy, or without specific reinforcement designs, often lack sufficient impact resistance (drop resistance). Utility Model Content
[0005] The purpose of this invention is to provide a shock-resistant and wear-resistant work lamp to solve the problems existing in the prior art.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A shock-resistant and wear-resistant work light includes a work light and a buffer module. The work light includes a grip and a light-emitting part. The buffer module includes a buffer disc, a buffer sleeve, and a buffer strip. The buffer disc, buffer sleeve, and buffer strip are all made of porous flexible material. The work light is bonded and fixed to the top center of the buffer disc. The buffer sleeve is fitted onto the grip of the work light. The buffer strip is bonded and fixed to the periphery of the light-emitting part. A protective eye cover is detachably installed on the light-emitting part of the work light.
[0008] By adopting the above technical solution, since the light-emitting part of the work light needs to be oriented towards the grinding and sandblasting direction for a long time, some of the flying sand and gravel will bounce back and hit the light-emitting part of the work light. Over time, this will cause damage to the light-emitting part. Therefore, a detachable protective cover is installed on the light-emitting part. The protective cover is replaced after a period of use to ensure the brightness of the light and the service life of the light-emitting part. The area of the buffer disc is larger than the area of the work light, so the buffer disc will protect the bottom of the work light in the event of a collision. When it falls, the buffer disc will also hit the ground first. This structure provides comprehensive protection for the work light and increases its service life.
[0009] In a further embodiment, the working light is horizontally disposed on the top of the buffer disk, the light-emitting part is used to emit a light beam in the forward direction, one end of the buffer strip is fixedly installed on the top of the buffer disk, and the other end of the buffer strip is detachably installed on the top of the buffer disk.
[0010] By adopting the above technical solution, the middle section of the buffer strip is wrapped around the periphery of the light-emitting part at least once, and two ends will appear. It can be detached by knotting. When the knot is loosened, the buffer strip can be separated from the light-emitting part of the work light, which makes it easy to replace the light-emitting part or the goggles.
[0011] In a further embodiment, a rope is embedded inside the buffer strip.
[0012] By adopting the above technical solution, the rope is generally made of nylon to increase the tensile strength of the buffer strip and prevent the buffer rope from breaking directly when it is knotted and fixed.
[0013] In a further embodiment, the goggle includes a sleeve and a lens, the inner wall of the sleeve is configured as a threaded surface, the lens is fixedly installed at one end of the sleeve and is used to completely seal one end of the sleeve, and the sleeve is screwed onto the light-emitting part.
[0014] By adopting the above technical solution, the screw connection method can achieve rapid replacement.
[0015] In a further embodiment, a PE film is adhered and fixed to one side of the lens.
[0016] By adopting the above technical solution, the PE film prevents the lens fragments from scattering everywhere after the lens breaks, making it easier to collect and dispose of the fragments.
[0017] In a further embodiment, a plurality of gravity blocks are embedded in the top periphery of the buffer disk.
[0018] By adopting the above technical solution, the gravity block is used to ensure that the bottom surface of the buffer disc lands first when it falls. Generally speaking, assuming that the weight of a work light is 1.5KG, the total weight of the gravity blocks should be about 0.1-0.2KG. This is because the drop height that this device needs to prevent is between 1-1.5 meters. If the drop height is higher, the basic protective measures will be ineffective, or in other words, for higher heights, the value of the protective measures far exceeds the value of the work light itself. After a fall, it is better to simply replace the work light itself.
[0019] In summary, this utility model has the following beneficial effects:
[0020] 1. By installing a removable protective cover on the light-emitting part, the brightness of the light and the service life of the light-emitting part can be guaranteed by replacing the protective cover after a period of use. The area of the buffer disc is larger than that of the work light, so the buffer disc will protect the bottom of the work light in the event of a collision. When it falls, the buffer disc will also hit the ground first. This structure provides comprehensive protection for the work light and increases its service life. Attached Figure Description

[0026] Example 1:
[0027] like Figures 1-2 As shown, a shock-resistant and wear-resistant work lamp includes a work lamp 1 and a buffer module 2. The work lamp 1 includes a grip part 11 and a light-emitting part 12. The buffer module 2 includes a buffer disc 21, a buffer sleeve 22, and a buffer strip 23. The buffer disc 21, buffer sleeve 22, and buffer strip 23 are all made of porous flexible material. The work lamp 1 is bonded and fixed to the top center of the buffer disc 21. The buffer sleeve 22 is fitted onto the grip part 11 of the work lamp 1. The buffer strip 23 is bonded and fixed to the periphery of the light-emitting part 12. A protective eyepiece 3 is detachably installed on the light-emitting part 12 of the work lamp 1. The work lamp 1 is arranged horizontally. At the top of the buffer disc 21, the light-emitting part 12 is used to emit a light beam forward. One end of the buffer strip 23 is fixedly installed on the top of the buffer disc 21, and the other end of the buffer strip 23 is detachably installed on the top of the buffer disc 21. A rope is embedded inside the buffer strip 23. The goggle 3 includes a sleeve and a lens. The inner wall of the sleeve is set as a threaded surface. The lens is fixedly installed on one end of the sleeve and is used to completely seal one end of the sleeve. The sleeve is screwed onto the light-emitting part 12. A PE film is bonded and fixed to one side of the lens. Multiple gravity blocks are embedded in the top periphery of the buffer disc 21.
[0028] Specific implementation process: Because the light-emitting part of the work light needs to be facing the direction of sandblasting for a long time, some of the flying sand and gravel will bounce back and hit the light-emitting part of the work light. Over time, this will cause damage to the light-emitting part. Therefore, a detachable protective cover is installed on the light-emitting part. The protective cover is replaced after a period of use to ensure the brightness of the light and the service life of the light-emitting part. The area of the buffer disc is larger than that of the work light, so in the event of a collision, the buffer disc will protect the bottom of the work light. In the event of a fall, the buffer disc will also hit the ground first. This structure provides comprehensive protection for the work light and increases its lifespan. The gravity blocks are used to ensure that the bottom of the buffer disc lands first when it falls. Generally, assuming a work light weighs 1.5KG, the total weight of the gravity blocks should be about 0.1-0.2KG. This is because the device needs to prevent falls from a height of 1-1.5 meters. If the fall height is higher, the basic protective measures are ineffective, or rather, for higher heights, the value of the protective measures far exceeds the value of the work light itself. It would be better to replace the work light itself after a fall.
