Description

Technical Field

[0001] This utility model relates to the field of tri-color alarm light technology, specifically, to a retractable and bendable tri-color alarm light. Background Technology

[0002] Tri-color alarm indicator lights typically consist of red, yellow, and green lights and are widely used in various fields. Generally, green indicates that the equipment is in normal operation, yellow indicates that the equipment is in standby, warm-up, or paused state, and red indicates that the equipment has malfunctioned or is in an emergency requiring immediate shutdown or maintenance. Some tri-color alarm indicator lights are also equipped with a buzzer to provide a dual alarm signal (color and sound) in conjunction with the red indicator light, allowing relevant personnel to quickly notice any abnormalities.

[0003] Chinese patent CN211738823U discloses a three-color alarm light for production line early warning. Addressing the problem that existing three-color alarm lights are inconvenient to assemble and disassemble, making them difficult for maintenance personnel to remove and repair, the following solution is proposed: It includes a base with a rectangular groove at the top. A rectangular plate is fitted into the rectangular groove, and the top of the rectangular plate is fixedly connected to the three-color alarm light body. Side plates are fixedly connected to both sides of the rectangular plate. Side grooves with openings at the top are formed on the inner walls of both sides of the rectangular groove. The bottom of the side plate contacts the bottom inner wall of the side groove. A horizontal hole is formed on one inner wall of one side groove, and a first limiting plate is slidably installed in the horizontal hole. The bottom of the first limiting plate contacts the top of one side plate. This utility model has good practicality, facilitates the assembly and disassembly of the three-color alarm light body, and makes it convenient for maintenance personnel to repair the three-color alarm light body.

[0004] However, the height of the three-color alarm light for production line warning, with publication number CN211738823U, cannot be adjusted. Currently, commonly used three-color lights on the market face many limitations in terms of length and height, leading to various inconveniences when used on construction sites. These inconveniences mainly fall into two categories: inconveniences during use and inconveniences for manufacturers.

[0005] Inconvenience in use: Difficulty in adjusting the installation height: The height adjustment of some tri-color lights relies on a fixed-length rod or bracket, which users cannot flexibly adjust according to actual needs. Usually, the height can only be adjusted by bending the base of the tri-color light 180° to adapt to different installation positions on the equipment.

[0006] Lamp length adaptation issue: Some tri-color lamps have a fixed length and cannot be adjusted according to the size of the space. For example, in a small area, the lamp body and support rod installed on the top of the equipment may appear too high and oppressive, while in a large space, the tri-color lamp body on the top of the equipment may be too short, resulting in insufficient lighting coverage and failing to provide an effective alarm warning function.

[0007] Inconvenience for manufacturers: Because tri-color lights require different installation locations and heights, manufacturers need to design and produce a large number of bases to match different usage scenarios. This increases production costs, as different molds need to be designed and produced for different product bases. This indirectly increases production costs and corresponding inventory management costs. Utility Model Content

[0020] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0021] like Figure 1 As shown, a retractable and bendable tri-color alarm light according to this utility model includes: a lamp post assembly, an adjustable telescopic support rod assembly, a connecting base 12, an angle adjustment assembly, a base 16, and a spring power cord.

[0022] The lamp post assembly is mounted on top of the adjustable telescopic support rod assembly. The lamp post assembly can be adjusted in height as the adjustable telescopic support rod assembly is adjusted.

[0023] The adjustable telescopic support rod and the connecting base 12 have a hollow structure. The adjustable telescopic support rod includes a first lifting support column 5, a second lifting support column 8, a third lifting support column 10, a first fastening knob 7, a second fastening knob 9, a third fastening knob 11, a first lifting support column limit buckle 24, a second lifting support column limit buckle 25, and a third lifting support column limit buckle 26. Specifically, the first lifting support column 5, the second lifting support column 8, the third lifting support column 10, the first fastening knob 7, the second fastening knob 9, and the third fastening knob 11 are all made of aluminum alloy.

[0024] The first lifting support column limiting buckle 24 is located on the top of the inner wall of the second lifting support column 8, and the first fastening knob 7 is located on the top of the outer wall of the second lifting support column 8. The first fastening knob 7 controls the expansion or contraction of the first lifting support column limiting buckle 24 by rotation.

[0025] The first lifting support column 5 is inserted into the first lifting support column limiting buckle 24. The diameter of the first lifting support column 5 is smaller than the diameter of the second lifting support column 8. The first lifting support column 5 can be inserted into the second lifting support column 8. When the first lifting support column limiting buckle 24 expands, the first lifting support column 5 can move inside the second lifting support column 8, moving the first lifting support column 5 relative to the top of the second lifting support column 8 to the desired position. The first fastening knob 7 rotates to control the first lifting support column limiting buckle 24 to retract, fixing the position of the first lifting support column 5 to the top of the second lifting support column 8. Any position of the first lifting support column 5 can be fixed inside the top of the second lifting support column 8 by the first lifting support column limiting buckle 24.

[0026] The second lifting support column limit buckle 25 is located on the top of the inner wall of the third lifting support column 10, and the second fastening knob 9 is located on the top of the outer wall of the third lifting support column 10. The second fastening knob 9 controls the expansion or contraction of the second lifting support column limit buckle 25 by rotation.

[0027] The second lifting support column 8 is inserted into the second lifting support column limiting buckle 25. The diameter of the second lifting support column 8 is smaller than the diameter of the third lifting support column 10. The second lifting support column 8 can be inserted into the third lifting support column 10. When the second lifting support column limiting buckle 25 expands, the second lifting support column 8 can move within the third lifting support column 10. The second lifting support column 8 is moved relative to the third lifting support column 10 to the desired position. The second fastening knob 9 is rotated to control the second lifting support column limiting buckle 25 to retract, fixing the position of the second lifting support column 8 to the top of the third lifting support column 10. Any position of the second lifting support column 8 is fixed to the top of the third lifting support column 10 by the second lifting support column limiting buckle 25.

[0028] The third lifting support column limit buckle 26 is located on the top of the inner wall of the connecting base 12, and the third fastening knob 11 is located on the top of the outer wall of the connecting base 12. The third fastening knob 11 is used to control the expansion or contraction of the third lifting support column limit buckle 26.

[0029] The third lifting support column 10 is inserted into the connecting base 12. The diameter of the third lifting support column 10 is smaller than the diameter of the connecting base 12. The third lifting support column 10 can be inserted into the connecting base 12. When the third lifting support column limiting buckle 26 expands, the third lifting support column 10 can move within the connecting base 12, moving the third lifting support column 10 relative to the top of the connecting base 12 to the desired position. The third fastening knob 11 rotates to control the third lifting support column limiting buckle 26 to retract, fixing the position of the third lifting support column 10 to the top of the connecting base 12. Any position of the third lifting support column 10 is fixed to the top of the connecting base 12 by the third lifting support column limiting buckle 26.

[0030] The angle adjustment assembly includes an upper part angle adjustment limit wheel 13, a limit screw 14, and a lower part angle adjustment limit wheel 15; The top of the upper half angle adjustment limiting wheel 13 is connected to the third fastening knob 11 via the connecting base 12; the lower half angle adjustment limiting wheel 15 is connected to the upper half angle adjustment limiting wheel 13 via the limiting screw 14; the bottom of the lower half angle adjustment limiting wheel 15 is fixed to the base 16; the base is an ABS material base that can be folded 180°. The limiting screw 14 is used to adjust the angle between the upper half angle adjustment limiting wheel 13 and the lower half angle adjustment limiting wheel 15 by adjusting the tightness.

[0031] A spring power cable is threaded through the adjustable telescopic support rod assembly, the connecting base 12, and the angle adjustment assembly; one end of the spring power cable is connected to the lamp post assembly, and the other end is connected to the power source. The spring power cable can extend and retract to adapt to the extended length of the first lifting support column 5, the second lifting support column 8, and the third support column 10.

[0032] According to the actual working conditions, when the height of the three-color light needs to be changed, firstly, by rotating the first fastening knob 7, the second fastening knob 9, and the third fastening knob 11, the corresponding first lifting support column limit buckle 24, the second lifting support column limit buckle 25, or the third lifting support column limit buckle 26 are respectively in an expanded state, so that the first lifting support column 5 can move within the second lifting support column 8, the second lifting support column 8 can move within the third lifting support column 10, or the third lifting support column 10 can move within the connecting base 12.

[0033] The relationship between the lifting support columns is adjusted so that after the first lifting support column 5, the second lifting support column 8, and the third lifting support column 10 are extended and retracted respectively, the total length of the adjustable telescopic support rod assembly meets the required requirements. During the extension and retraction of the first lifting support column 5, the second lifting support column 8, and the third lifting support column 10, the spring power lines passing through the adjustable telescopic support rod assembly and the connecting base 12 are stretched accordingly.

[0034] Rotating the first fastening knob 7, the second fastening knob 9, and the third fastening knob 11 will retract the first lifting support column limit latch 24, the second lifting support column limit latch 25, and the third lifting support column limit latch 26, respectively. The first lifting support column limit buckle 24, the second lifting support column limit buckle 25, and the third lifting support column limit buckle 26 firmly grip the corresponding support column, thus completing the fixation of each lifting support column.

[0035] After adjusting the extension of the support column assembly, the angle between the upper half angle adjustment limit wheel 13 and the lower half angle adjustment limit wheel 15 of the tri-color light can be adjusted by tightening the adjustment limit screw 14, achieving an adjustment from 0° to 180°. This ensures that the tri-color light is in the optimal warning position.

[0036] The height of the lamp post assembly is adjustable through a hollow, adjustable telescopic support rod assembly, a connecting base, and a stretchable spring wire. This allows for stepless adjustment of three length segments, overcoming the lack of flexibility caused by the difficulty in adjusting the installation height of existing three-color alarm indicator lights. The height of the same alarm three-color light can be easily adjusted via a knob, adapting to different usage scenarios. Specifically, by adjusting the length of the adjustable telescopic support rod assembly, the same light can be adapted to different usage scenarios, improving the uneven distribution of the three-color light and the unclear visual effect caused by insufficient height, thus avoiding safety hazards caused by insufficient support height and unclear visual effect. Furthermore, the angle adjustment component allows the alarm three-color light to be bent, achieving adjustments from 0° to 180°, ensuring the entire three-color light is in the optimal warning position. The base and lamp post assembly share the same base, making it suitable for multiple usage scenarios and saving production costs and corresponding inventory management costs.

[0037] In one feasible implementation, a first lifting support column limiting groove 21 is provided at the bottom of the outer wall of the first lifting support column 5; when the first lifting support column 5 is at its maximum extension adjustment degree, that is, when the first lifting support column 5 is pulled out from the second lifting support column 8 to its maximum extent, the first lifting support column limiting groove 21 engages with the first lifting support column limiting buckle 24, thereby preventing the first lifting support column 5 from falling out of the second lifting support column 8.

[0038] The bottom of the outer wall of the second lifting support column 8 is provided with a second lifting support column limiting groove 22; when the second lifting support column 8 is at its maximum extension adjustment degree, that is, when the second lifting support column 8 is pulled out of the third lifting support column 10 to the maximum extent, the second lifting support column limiting groove 22 and the second lifting support column limiting buckle 25 are engaged, preventing the second lifting support column 8 from falling out of the third lifting support column 10.

[0039] The bottom of the outer wall of the third lifting support column 10 is provided with a third lifting support column limiting groove 23; when the third lifting support column 10 is at its maximum extension adjustment degree, that is, when the third lifting support column 10 is pulled out of the connecting base 12 to the maximum extent, the third lifting support column limiting groove 23 and the third lifting support column limiting buckle 26 are engaged, preventing the third lifting support column 10 from falling off the connecting base 12.

[0040] The first lifting support column limiting groove 21, the second lifting support column limiting groove 22, and the third lifting support column limiting groove 23 respectively engage with the first lifting support column limiting buckle 24, the second lifting support column limiting buckle 25, and the third lifting support column limiting buckle 26, respectively, to ensure the maximum adjustment range of the first lifting support column 5, the second lifting support column 8, and the third lifting support column 10, and to prevent the support columns from loosening due to excessive extension.

[0041] In one feasible embodiment, the lamp post assembly includes a lampshade top fixing member 1, a transparent lampshade 2, and a tri-color lamp post 3. The lampshade top fixing member 1 is installed on top of the transparent lampshade 2 for fixing the transparent lampshade 2 to the tri-color lamp post 3.

[0042] In one feasible implementation, the lampshade top fixing member 1 is an ABS plastic lampshade top fixing member; the tri-color lamp post 4 is an ABS plastic tri-color lamp post; and the transparent lampshade 2 is a highly transparent PC plastic transparent lampshade.

[0043] In one feasible implementation, the lamp post assembly also includes a buzzer and a buzzer sound hole. The buzzer is installed on one side of the tri-color lamp post 4, and the buzzer sound hole 3 is installed between the transparent lamp cover 2 and the tri-color lamp post 4.

[0044] In one feasible implementation, the lamp post assembly further includes a connector 19, which is disposed on the tri-color lamp post 4 for connecting the tri-color lamp post 4 and the spring power cord.

[0045] In one feasible embodiment, the spring power cord includes a retractable portion 18 and a non-retractable portion 17. The retractable portion 18 is disposed within the adjustable telescopic support rod assembly. The non-retractable portion 17 is disposed within the angle adjustment assembly, with one end connected to the retractable portion 18 and the other end extending outwards towards the exterior of the alarm tri-color light. The retractable portion 18 extends and retracts with changes in the length of the adjustable telescopic support rod assembly, while the non-retractable portion 17 can be fixed within the angle adjustment assembly, thus not affecting changes in the length of the adjustable telescopic support rod assembly. Furthermore, the remaining portion is designed to be non-retractable, saving raw materials for the power cord.

[0046] In one feasible implementation, the bottom of the base 16 is provided with an anti-slip pad to prevent the retractable and bendable tri-color alarm light from slipping during use.

[0047] In one feasible implementation, limit extension grooves 6 are respectively provided on the side walls of the first lifting support column 5, the second lifting support column 8, and the third lifting support column 10.

[0048] The figure shows the limiting extension groove 6 on the first lifting support column 5. Taking the limiting extension groove 6 on the first lifting support column 5 as an example, the limiting extension groove 6 on the side wall of the second lifting support column 8 and the third lifting support column 10 has the same function as the limiting extension groove 6 on the first lifting support column 5.

[0049] One end of the limiting extension groove 6 is connected to the limiting groove 21 of the first lifting support column, and the other end extends upward in the vertical direction.

[0050] The first lifting support column limiting buckle 24 partially engages with the groove of the limiting extension groove 6. When the first lifting support column limiting buckle 24 reaches the bottom of the limiting extension groove 6, the bottom of the limiting extension groove 6 blocks the first lifting support column limiting buckle 24, and the first lifting support column 5 will not detach from the second lifting support column 8.

[0051] Furthermore, the limiting extension groove 6 provides an additional guide path for the lifting of the first lifting support column 5, preventing the first lifting support column 5 from rotating or swaying laterally during the lifting process, ensuring smooth and precise movement, and reducing wear and noise.
