Description

Technical Field

[0001] The utility model relates to a visual status indicator light applied to a safety light curtain, belonging to the technical field of protective equipment. Background Art

[0002] Safety light curtains, also known as safety gratings, are safety protection products primarily used to prevent people from entering or interfering with hazardous areas, ensuring operator safety. They primarily consist of an emitter and a receiver. The emitter emits modulated infrared light, which is received by the receiver, forming a protective light curtain. If an object enters the protective screen or blocks the beam, the receiver outputs a signal, halting the equipment or triggering an alarm, thereby preventing accidents.

[0003] When in use, some safety light curtains will display their status through indicator lights installed on the safety light curtains, allowing workers to judge whether the installed light curtains are working properly based on the color and shape of the indicator lights. However, the indicator lights on some safety light curtains are placed on the light-transmitting surface of the light curtains, which is not easy for operators to observe intuitively. When the indicator lights react, the operator may not know it at the first time. If the operator makes a wrong operation at this time, there will be certain dangers. To this end, we provide a visual status indicator light applied to the safety light curtain to solve the above problems. Utility Model Content

[0004] In order to solve the above problems, the present invention provides a visual status indicator light applied to a safety light curtain to solve the above problems. The specific technical solution is as follows:

[0005] A visual status indicator light applied to a safety light curtain comprises a safety light curtain body, a light guide groove is provided inside the safety light curtain body, a refraction plate is connected to the inner side wall of the light guide groove, a light-transmitting plate is installed inside the safety light curtain body, an indicator light is installed inside the safety light curtain body, a partition plate is installed inside the safety light curtain body, a storage box is connected to the outer surface of the safety light curtain body, a limiting frame is slidably connected to the interior of the storage box, a low-light plate is installed inside the limiting frame, and a limiting mechanism is provided on the outer surface of the safety light curtain body.

[0006] Preferably, the limiting mechanism includes a limiting shell, the outer surface of the limiting shell is connected to the outer surface of the storage box, the interior of the limiting shell is connected to a spring, and the end of the spring away from the limiting shell is connected to a plug plate.

[0007] Preferably, the outer surface of the inserting plate is slidably connected to a limiting block, the outer surface of the limiting block is connected to the outer surface of the limiting frame, and the outer surface of the inserting plate is connected to a push plate.

[0008] Preferably, the outer surface of the inserting plate is slidably connected to the interior of the limiting shell, the outer surface of the limiting block is slidably connected to the interior of the storage box, and the outer surface of the pushing plate is slidably connected to the interior of the limiting shell.

[0009] Preferably, a rubber pad is connected to the interior of the storage box, an outer surface of the rubber pad is slidably connected to the outer surface of the dimming plate, and a baffle is connected to the outer surface of the safety light curtain body.

[0010] Preferably, the outer surface of the deflecting plate is connected to the inner portion of the light-transmitting plate, and the outer surface of the limiting frame is slidably connected to the outer surface of the safety light curtain body.

[0011] Preferably, the outer surface of the partition plate contacts the inner portion of the light-transmitting plate, and the outer surface of the partition plate is connected to the outer surface of the indicator light.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The visual status indicator light applied to the safety light curtain is achieved through the cooperation between different components such as the refraction plate and the partition plate. First, the refraction plate can refract light. The refraction of light by the refraction plate allows the light emitted by the indicator light to fill the light guide groove, so that the light emitted by the indicator light can be illuminated on the three sides of the safety light curtain body, thereby facilitating the operator to monitor the status of the light curtain in real time. The partition plate can divide the indicator light into three layers. The division of the indicator light by the partition plate increases the light change mode, allowing the user to adjust the indicator light for more forms of transformation, so that the indicator light can convey more information, which is very convenient and solves the problem that users are not easy to detect the danger of light operation.

[0014] 2. The visual status indicator light applied to the safety light curtain is achieved through the cooperation between the low-light plate and the baffle. First, the low-light plate can be moved. By moving the low-light plate, it is blocked outside the light-transmitting plate, thereby reducing the intensity of light revealed by the light-transmitting plate, so that some people with keen vision will not feel the light is dazzling. The baffle can provide support for the limit frame, so that the limit frame will not continue to move after moving the low-light plate down to a certain position. It is very easy to use.

The plug plate 1003 will be inserted into the inside of the limit block 1004 to limit the position of the limit block 1004, so that the limit block 1004 cannot move up and down. The limit block 1004 will fix the position of the limit frame 8, so that after the plug plate 1003 is inserted into the limit block 1004, the limit frame 8 cannot move up and down. The plug plate 1003 will fix the position of the push plate 1005, and when the push plate 1005 moves, it will move with the plug plate 1003.

[0033] When the present invention is in use, first, the indicator light 5 will light up according to the situation of the safety light curtain body 1 itself. After the indicator light 5 lights up, the light emitted will be refracted by the deflecting plate 3. The light refracted by the deflecting plate 3 will fill the light guide groove 2, allowing users outside to observe the light through the translucent plate 4. If the light is too bright, the user can move the push plate 1005 to pull the plug plate 1003 out of the limit block 1004, and then the user can move the limit frame 8 to the baffle 12, so that the low-light plate 9 will cover the translucent plate 4, so that people who work in front of the device for a long time will not feel glare.
