Abstract
Description
Technical Field
[0001] This utility model relates to the field of safety barriers, and more particularly to an isolated safety barrier that is mounted on a rail. Background Technology
[0002] Safety barriers are devices used to isolate electrical equipment in hazardous and non-hazardous locations, limit the energy entering hazardous locations, and ensure safety. These rail-mounted isolation safety barriers are easy to install, simply snapping onto standard DIN rails, saving time and space and facilitating future maintenance and expansion. They offer excellent isolation performance, effectively blocking the transmission of hazardous energy, resisting interference, and ensuring accurate signal transmission. They possess intrinsically safe explosion-proof characteristics, limiting the energy of equipment entering hazardous locations to meet explosion-proof requirements. They also have strong signal processing capabilities, handling various industrial signals. Furthermore, their modular design facilitates system integration, improving automation levels and management efficiency.
[0003] The rail-mounted isolated safety barrier consists of a loop energy limiting unit, a signal isolation unit, and a power supply unit. In hazardous locations, the loop energy limiting unit restricts the energy flowing into the intrinsically safe circuit. In the event of a fault, it quickly controls the current and voltage within a safe range to prevent the generation of explosive energy. The signal isolation unit uses transformer, optoelectronic, and other isolation technologies to electrically isolate intrinsically safe and non-intrinsically safe signals, preventing fault propagation and interference. The power supply unit converts non-intrinsically safe power into a stable power supply adapted to the intrinsically safe circuit. After filtering and voltage regulation, the power is supplied. Each unit is electrically isolated from the others to ensure the stable operation of the entire safety barrier system.
[0004] However, a problem that cannot be ignored has been exposed during its use. Currently, the traditional connection method is inadequate when dealing with frequent disassembly of the equipment. After only a few disassembly operations, the connection between the safety barrier and the guide rail begins to become loose. This not only causes poor contact due to loosening during operation, affecting signal transmission and the normal operation of the safety barrier, but also seriously weakens its efficiency. Once a malfunction is caused by connection problems, it will also increase equipment maintenance costs and downtime, negatively impacting the stability of the entire production process. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a rail-mounted isolation safety barrier, which aims to improve the problem that traditional connection methods cause the equipment to become unstable after being disassembled several times during equipment use.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rail-mounted isolation safety barrier, comprising a safety barrier, a rotating shaft rotatably connected inside the safety barrier, an unlocking component provided on the outer wall of the rotating shaft, a blocking block fixedly connected to the outer wall of the rotating shaft, and a fixing component provided on one side of the safety barrier;
[0007] The unlocking component includes a linkage block, a push block, and a spring. One end of the linkage block is fixedly connected to the outer wall of the rotating shaft, one end of the push block is fixedly connected to one side of the linkage block, and the spring is disposed inside the safety barrier. One end of the spring is fixedly connected to the inside of the safety barrier, and the other end of the spring is fixedly connected to the inside of the linkage block.
[0008] As a further description of the above technical solution:
[0009] The fixing component includes a fixing strip and a guide rail. One side of the fixing strip is slidably connected to one side of the safety barrier, and one side of the guide rail is fixedly connected to one side of the fixing strip.
[0010] As a further description of the above technical solution:
[0011] The safety barrier has multiple screw holes fixedly connected to one side, and multiple insertion holes are provided inside the safety barrier.
[0012] As a further description of the above technical solution:
[0013] The safety barrier has multiple sliding grooves at its top and bottom, and multiple protective plates are slidably connected inside the safety barrier.
[0014] As a further description of the above technical solution:
[0015] Each of the protective plates is fixedly connected to a pull strip on its top, and each of the protective plates is fixedly connected to a sealing strip on its top.
[0016] As a further description of the above technical solution:
[0017] The screw holes are arranged in a symmetrical array on one side of the safety barrier, and the insertion holes are arranged in a symmetrical array on the top and bottom of the safety barrier.
[0018] As a further description of the above technical solution:
[0019] The outer wall of each of the protective plates is slidably connected to the inside of the sliding groove, and the protective plates are arranged in a symmetrical array at the top and bottom of the safety barrier.
[0020] As a further description of the above technical solution:
[0021] Each of the pull strips and sealing strips is arranged in a parallel array on the top of the protective plate, and the outer wall of each sealing strip is slidably connected to the inside of the safety barrier.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, the pressing block is first pressed to drive the linkage block to rotate using the rotating shaft, which compresses the spring and drives the blocking block to rotate, thus unlocking the safety barrier. Then, the safety barrier is grasped and lifted upwards to remove it. This achieves the effect of easily removing the safety barrier from the guide rail during equipment use, avoiding the problem that the traditional connection method causes the equipment to become unstable after several disassemblies, thereby improving the efficiency of the guide rail-mounted isolation safety barrier.
[0024] 2. In this utility model, the pull bar is first grasped and pulled outward, thereby causing the fingers to drive the pull bar to disengage the protective plate from the sliding groove. At the same time, the sealing strip is squeezed by the inner wall of the safety barrier and then disengages from the safety barrier as it moves. This achieves the effect of protecting the insertion hole of the equipment when it is not in use during the equipment's operation. It avoids the problem of excessive dust accumulation inside the insertion hole due to prolonged exposure to air during the equipment's operation, which affects subsequent use. This improves the practicality of the rail-mounted isolation safety barrier. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a rail-mounted isolation safety barrier, comprising a safety barrier 1, a rotating shaft 2 rotatably connected inside the safety barrier 1 for rotating a blocking block 3, an unlocking component provided on the outer wall of the rotating shaft 2 for controlling the connection between the safety barrier 1 and the rail 8, a blocking block 3 fixedly connected on the outer wall of the rotating shaft 2 for fixing the safety barrier 1, and a fixing component provided on one side of the safety barrier 1 for connecting the safety barrier 1.
[0034] The unlocking component includes a linkage block 4, a push block 5, and a spring 6. One end of the linkage block 4 is fixedly connected to the outer wall of the rotating shaft 2 to connect the push block 5 and the rotating shaft 2. One end of the push block 5 is fixedly connected to one side of the linkage block 4 to drive the blocking block 3 to move. The spring 6 is set inside the safety barrier 1 to provide support for the blocking block 3. One end of the spring 6 is fixedly connected to the inside of the safety barrier 1, and the other end of the spring 6 is fixedly connected to the inside of the linkage block 4. The fixing component includes a fixing strip 7 and a guide rail 8. One side of the fixing strip 7 is slidably connected to one side of the safety barrier 1 to fix the guide rail 8 to the wall. One side of the guide rail 8 is fixedly connected to one side of the fixing strip 7 to provide directional support for the movement of the safety barrier 1.
[0035] Specifically, when it is necessary to remove the safety barrier 1 from its installation position, first, locate the push block 5 near the safety barrier 1, and gently press the push block 5 with your finger to drive the linkage block 4 to rotate smoothly around the pivot 2. At the same time, the spring 6, which works in conjunction with the linkage block 4, will be strongly compressed and gradually contract. During this series of actions, the rotation of the linkage block 4 will also drive the blocking block 3 to rotate. When the blocking block 3 rotates to a certain angle, the locking state of the safety barrier 1 will be released. At this time, the operator can hold the safety barrier 1 and lift it upwards to successfully remove the safety barrier 1 completely from the installation position.
[0036] Reference Figure 3The safety barrier 1 has multiple screw holes 9 fixedly connected to one side for connecting screws to fix the wires. The safety barrier 1 has multiple insertion holes 10 inside for connecting the wires. The top and bottom of the safety barrier 1 have multiple sliding grooves 11 for accommodating the protective plates 12. Multiple protective plates 12 are slidably connected inside the safety barrier 1 to protect the insertion holes 10. Each protective plate 12 has a pull strip 13 fixedly connected to its top for pulling the protective plate 12. Each protective plate 12 has a sealing strip 14 fixedly connected to its top for sealing the gap between the protective plate 12 and the safety barrier 1. The screw holes 9 are arranged in a symmetrical array on one side of the safety barrier 1. The insertion holes 10 are arranged in a symmetrical array on the top and bottom of the safety barrier 1. The outer wall of each protective plate 12 is slidably connected inside the sliding groove 11. The protective plates 12 are arranged in a symmetrical array on the top and bottom of the safety barrier 1. Each pull strip 13 and sealing strip 14 are arranged in a parallel array on the top of the protective plate 12. The outer wall of each sealing strip 14 is slidably connected inside the safety barrier 1.
[0037] Specifically, when it is necessary to activate the corresponding insertion hole 10 on the safety barrier 1, the operator first locates the pull bar 13 on one side of the protective plate 12 and grasps it with their fingers. Then, the operator applies force to pull the pull bar 13 outwards from the safety barrier 1. As the pulling action continues, the operator's fingers move the pull bar 13, causing the protective plate 12, which was originally tightly fitted inside the sliding groove 11, to gradually detach from the sliding groove 11 under the pull of the pull bar 13. During this process, the sealing strip 14 connected to the edge of the protective plate 12 comes into close contact with the inner wall of the safety barrier 1 and is subjected to strong pressure from the inner wall. As the protective plate 12 moves outwards, the sealing strip 14 gradually detaches from the inside of the safety barrier 1. At this point, the corresponding insertion hole 10, which was originally covered by the protective plate 12, is fully exposed. The operator can then accurately insert the wire to be connected into the insertion hole 10 to complete the electrical connection operation.
[0038] Working principle: When using the rail-mounted isolation safety barrier, to remove the safety barrier 1, first press the actuating block 5 to drive the linkage block 4 to rotate using the rotating shaft 2, which compresses the spring 6 and simultaneously drives the blocking block 3 to rotate, thus unlocking the safety barrier 1. Then, grasp the safety barrier 1 and lift it upwards to remove it. When the corresponding insertion hole 10 is needed, first grasp the pull bar 13 and pull it outwards, which will cause your fingers to drive the pull bar 13 to disengage the protective plate 12 from the sliding groove 11. At the same time, the sealing strip 14 is squeezed by the inner wall of the safety barrier 1 and then disengages from the inside of the safety barrier 1 as it moves, exposing the corresponding insertion hole 10. Then, insert the wire into the hole for connection.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
