Description

Technical Field

[0001] The present application relates to the technical field of lamps, and in particular to a warning light. Background Art

[0002] A warning light, also known as a warning light or alarm, is a lamp used to issue warnings. A warning light uses light, sound, and other means to achieve the purpose of warning when a warning or reminder is needed. A warning light usually has multiple lamp bodies that emit different lights, and the multiple lamp bodies are detachably connected to adapt to different scenarios.

[0003] In the related technology, the warning light includes a base and multiple lamp bodies. The base is equipped with electrical components. A plug is provided on the end face of the base, a plug is provided on one end of the lamp body, and a socket is provided on the other end of the lamp body. When the plug is inserted into the socket, the lamp body and the base are electrically connected to each other or different lamp bodies are electrically connected to each other. Different lamp bodies are connected by threads, and a sealing ring is located between two adjacent lamp bodies.

[0004] Since the sealing ring is located between the two lamp bodies and the lamp bodies are unlocked and locked by threaded connections, when the lamp bodies are replaced, the two adjacent lamp bodies are rotated away from each other, causing different forces to act on both sides of the sealing ring. The sealing ring may be deformed, causing the sealing ring to move toward the outside of the lamp body, causing the sealing ring to fail to seal the lamp body, which in turn causes water to easily enter between the lamp bodies, affecting the use of the lamp bodies. Utility Model Content

[0005] In order to improve the problem that the sealing ring is easily separated from two adjacent lamp bodies, the present application provides a warning light.

[0006] The present application provides a warning light, which adopts the following technical solution:

[0007] A warning light comprises a base and a plurality of lamp bodies, wherein a fixing sleeve is rotatably connected to the lamp body, a locking piece is provided on the fixing sleeve, and the locking piece fixes two adjacent fixing sleeves by rotating, an annular groove for inserting the fixing sleeve is provided on the fixing sleeve, a sealing ring is provided in the annular groove, and the sealing ring is located between the annular groove and the adjacent fixing sleeves.

[0008] By adopting the above technical solution, when two adjacent fixing sleeves are rotated to unlock, the sealing ring is located between the annular groove and the adjacent fixing sleeves, one side of the sealing ring is restricted by the fixing sleeve, and the other side of the sealing ring is restricted by the wall of the annular groove, so that the sealing ring can be fixed between the two fixing sleeves, avoiding the sealing ring from deforming toward the outside of the fixing sleeves and separating from the fixing sleeves when the two fixing sleeves are rotated, thereby increasing the sealing effect of the sealing ring on the two adjacent fixing sleeves.

[0009] Optionally, the locking member includes a fixing block, which is located on one end of the fixing sleeve, and a fixing groove for inserting the fixing block is provided on the other end of the fixing sleeve, and a stopping groove for inserting the fixing block is provided on the groove wall of the fixing groove, and the stopping groove does not penetrate to the end surface of the fixing sleeve, and when the fixing block is inserted into the stopping groove, the two adjacent fixing sleeves are locked with each other.

[0010] By adopting the above technical solution, people first insert the fixing block into the fixing groove, and then rotate the fixing block to move the fixing block from the fixing groove to the stopping groove. Since the stopping groove does not penetrate the end face of the fixing sleeve, the groove wall of the stopping groove restricts the fixing block, so that the fixing block cannot directly escape from the stopping groove, thereby allowing the two adjacent fixing sleeves to be fixed to each other and preventing the two fixing sleeves from being directly separated.

[0011] Optionally, a limiting rod is provided on one end of the lamp body, and a limiting groove for sliding the limiting rod is opened on the other end of the lamp body, and the length of the limiting groove is the distance that the fixing block rotates from the fixing groove to the stopping groove.

[0012] By adopting the above technical solution, the limiting rod slides in the limiting groove, and the groove wall of the limiting groove limits the limiting rod. Since the length of the limiting groove is the distance that the fixed block rotates from the fixed groove to the stop groove, the rotation distance of the fixed block is fixed; and the limiting rod and the fixed block share the force together, reducing the force on the fixed block caused by excessive rotation, reducing the damage to the fixed block caused by excessive rotation, thereby extending the service life of the fixed block.

[0013] Optionally, an anti-dropout block is provided on the fixing sleeve, and an anti-dropout groove for inserting the anti-dropout block is opened in the stopping groove. When the anti-dropout block is inserted into the anti-dropout groove, the fixing block is located in the stopping groove.

[0014] By adopting the above technical solution, the anti-slip block is inserted into the anti-slip groove, so that the fixed block is located in the stopping groove, and the groove wall of the anti-slip groove restricts the anti-slip block, so that the fixed block can be stably located in the stopping groove, avoiding the fixed block from moving in the stopping groove, further strengthening the fixing effect of the fixed block in the stopping groove, and making the two adjacent fixing sleeves more secure.

[0015] Optionally, a light source component and an inner shell are provided in the lamp body, the inner shell is inclined toward the fixing sleeve and away from the light source component, the inner shell is located in the path of light emitted by the light source component, and the inner shell is used to reflect light.

[0016] By adopting the above technical solution, the inner shell is tilted toward the fixed sleeve and away from the light source, and the inner shell is located in the path of light emitted by the light source, so that the light emitted by the light source can be reflected by the tilt of the inner shell, and the light is emitted from the outer surface of the fixed sleeve, so that people can see the light more clearly.

[0017] Optionally, corrugated strips are provided on the inner wall of the fixing sleeve.

[0018] By adopting the above technical solution, since the corrugated strips are arranged on the inner wall of the fixing sleeve, the light can be scattered by the corrugated strips when reflected on the inner wall of the fixing sleeve, so that the brightness of the light can be reduced to avoid the light being too glaring and affecting people's operation.

[0019] Optionally, the inner shell includes a first shell and a third shell, the first shell is located on a side of the third shell away from the fixing sleeve, a plurality of scattering grooves are formed on an outer wall of the fixing sleeve, and the scattering grooves are located on a path of light reflected by the third shell.

[0020] By adopting the above technical solution, since the first shell is located on the side of the third shell away from the fixed sleeve, the intensity of the light reflected in the first shell is smaller than the intensity of the light reflected in the third shell. In addition, the scattering groove scatters the light reflected by the third shell, so that the light reflected by the third shell can be more uniform and extensive, and the light reflected by the first shell and the light reflected by the third shell are not dazzling, thereby increasing visibility and warning effects, and reducing the glare of light.

[0021] Optionally, a plug is provided on one end of the lamp body, and a socket is provided on the other end of the lamp body. The plug is cylindrical, and a receiving groove for inserting the plug is provided on the socket.

[0022] By adopting the above technical solution, the plug is cylindrical and can be inserted into the receiving groove. When the fixing sleeve is being disassembled, the plug is not easily damaged, thereby extending the service life of the plug.

[0023] Optionally, the socket includes a supporting seat and a connecting block, the connecting block is located in the supporting seat, the accommodating groove is formed on the connecting block, and a through hole communicating with the accommodating groove is formed on the connecting block.

[0024] By adopting the above technical solution, when the plug is inserted into the receiving groove, the plug abuts the connecting block. Since the perforation connects the receiving groove, the connecting block has a certain deformation space, so that the plug can be more firmly fixed on the connecting block, thereby achieving fixation of the plug and the socket.

[0025] Optionally, there are multiple plugs and sockets, an anti-error rod is provided on one end of the lamp body, and an anti-error groove for inserting the anti-error rod is opened on the other end of the lamp body, and the inner wall of the anti-error groove is flat on one side and curved on the other side. When the anti-error rod is inserted into the anti-error groove, the plug is inserted into the socket.

[0026] By adopting the above technical solution, the anti-error rod is inserted into the anti-error groove. Since one side of the inner wall of the anti-error groove is a plane and the other side is an arc surface, the anti-error rod cannot be inserted into the anti-error groove at a wrong angle, so that the plug and the socket can be matched one by one, avoiding the plug from matching with the wrong socket.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. When two adjacent fixing sleeves are rotated and unlocked, the sealing ring is located between the annular groove and the adjacent fixing sleeves, and one side of the sealing ring is restricted by the fixing sleeve, and the other side of the sealing ring is restricted by the wall of the annular groove, so that the sealing ring can be fixed between the two fixing sleeves, and the sealing ring is prevented from deforming toward the outside of the fixing sleeves and separating from the fixing sleeves when the two fixing sleeves rotate, thereby increasing the sealing effect of the sealing ring on the two adjacent fixing sleeves.

[0029] 2. People first insert the fixing block into the fixing groove, and then rotate the fixing block to move the fixing block from the fixing groove to the retaining groove. Since the retaining groove does not penetrate the end face of the fixing sleeve, the groove wall of the retaining groove restricts the fixing block, so that the fixing block cannot directly escape from the retaining groove, thereby allowing the two adjacent fixing sleeves to be fixed to each other and preventing the two fixing sleeves from being directly separated.
