Description

Technical Field

[0001] This utility model relates to the field of buckle device technology, and in particular to a mechanical release device. Background Technology

[0002] The housing of a mechanical trip unit is typically made of high-strength engineering plastics and metals. Engineering plastics, such as polycarbonate, have good insulation, impact resistance, and corrosion resistance, effectively protecting the internal mechanical structure from external environmental factors. Metal housings are mostly made of aluminum alloy, which has the advantages of high strength and good heat dissipation, making it suitable for use in high-load or high-temperature environments. The shape design of the housing generally follows the principle of compactness and rational use of space. At the same time, considering the convenience of installation, the housing surface may have mounting holes and fixing slots. The housing provides protection for internal components, not only preventing physical collisions from damaging the device, but also providing a certain degree of electromagnetic shielding, reducing the impact of external electromagnetic interference on the normal operation of the trip unit. In environments with dense electrical equipment, good electromagnetic shielding can ensure the accuracy of the trip unit's operation.

[0003] Some mechanical trip units are also equipped with tripping force adjustment devices, allowing users to adjust the tripping sensitivity according to the actual application scenario and circuit requirements. By adjusting the spring force and structural parameters, the tripping force can be controlled. Mechanical trip units are important safety devices, widely used in various mechanical and electrical installations, used to quickly release or disconnect circuits under specific conditions to protect equipment and personnel. However, existing mechanical trip units lack electric shock protection. When a person accidentally comes into contact with a live part, the mechanical trip unit cannot cut off the circuit in time. Furthermore, long-term leakage can accelerate the aging of electrical equipment and wiring, increasing the probability of malfunctions. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a mechanical trip device, which aims to improve the problem that existing mechanical trip devices do not have electric shock protection functions, and when a person accidentally comes into contact with a live part, the mechanical trip device cannot cut off the circuit in time, causing a dangerous situation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mechanical trip device, comprising a housing, wherein movable rods are slidably connected to the left and right sides of the housing, rollers are rotatably connected to the opposite sides of the two movable rods, and rotating shafts are rotatably connected to the adjacent sides of the two movable rods. A connecting rod is rotatably connected to the outer wall of the rotating shaft, a control closing device is rotatably connected to the bottom end of the left connecting rod, and a control opening device is rotatably connected to the bottom end of the right connecting rod. Long tracks are provided on the left and right ends of the front side of the housing, and springs are provided on the outer wall of the movable rods.

[0012] As a further description of the above technical solution:

[0013] The inner side of the elongated track is slidably connected to the outer wall of the corresponding rotating shaft.

[0014] As a further description of the above technical solution:

[0015] The box has a U-shaped design.

[0016] As a further description of the above technical solution:

[0017] Each of the aforementioned rotating shafts is equipped with a trip unit 2 on its front side.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, the left-side head control is used to close the circuit breaker, and the right-side control is used to open the circuit breaker. Both ends have rollers for easy movement. As the entire box moves, the rollers on both sides slide on the external raceway. The left-side closing control rod is pressed and moves first, driving the middle connecting rod to move upward, thereby controlling the external switch to close. The right-side opening control rod is also pressed and moves to open the circuit breaker. At this time, the left-side closing control rod is reset by the spring. Therefore, its function is to provide protection against electric shock and leakage when there is leakage in the line or electric shock to a person. The leakage current is amplified by the integrated circuit. When the set value is reached, the power is cut off within 0.1 seconds by the leakage current trip device. Attached Figure Description

[0027] 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.

[0028] Please see the appendix Figure 1 - Appendix Figure 3This utility model provides an embodiment of a mechanical trip device, including a housing 1. Movable rods 5 are slidably connected to the left and right sides of the housing 1. Rollers 4 are rotatably connected to the opposite sides of the two movable rods 5. Rollers 4 are also installed on the opposite sides, i.e., the outer sides. The design of the rollers 4 makes the entire device more flexible and convenient to move and adjust its position. Rotating shafts 9 are rotatably connected to adjacent sides of the two movable rods 5. A connecting rod 6 is rotatably connected to the outer wall of the rotating shaft 9. The outer wall of the rotating shaft 9 is cleverly rotatably connected to the connecting rod 6. This connection method ensures that the connecting rod 6 can swing flexibly around the rotating shaft 9. A control closing 3 is rotatably connected to the bottom of the left connecting rod 6, and a control opening 2 is rotatably connected to the bottom of the right connecting rod 6. Long tracks 12 are provided on the left and right sides of the front side of the housing 1. Through the restriction and guidance of the long tracks 12, the movable rods 5 can slide smoothly on a predetermined trajectory. Springs 7 are provided on the outer walls of the movable rods 5. Reserved holes 11 are provided on the left and right sides of the bottom inner side of the housing 1.

[0029] Specifically, the sliding connection mechanism of the housing 1 connects the moving rods 5. These two moving rods 5 can slide smoothly on the side of the housing 1, reducing frictional resistance and improving efficiency. Adjacent sides of the two moving rods 5, i.e., the side closest to the center of the housing 1, are rotatably connected to the rotating shaft 9, thus achieving effective control of the closing control 3 and the opening control 2. The bottom end of the left connecting rod 6 is rotatably connected to the closing control 3, while the bottom end of the right connecting rod 6 is rotatably connected to the opening control 2. This design allows the moving rods 5 to slide on the side of the housing 1, driving the closing control 3 and the opening control 2 to open and close through the transmission action of the connecting rod 6. These elongated tracks 12 not only provide stable guidance for the sliding of the moving rods 5 but also ensure the accuracy and reliability of the entire control process, thereby achieving precise control of the closing control 3 and the opening control 2.

[0030] Please see the appendix Figure 4 - Appendix Figure 5 The left and right ends of the outer wall of the moving rod 5 are equipped with release devices 8, which separate the moving rod 5 from the corresponding connecting parts, thereby ensuring the safety and reliability of the entire device. This not only improves the functionality of the moving rod 5, but also ensures that the other end of the spring 7 is in contact with the left and right sides of the outer wall of the box 1. The inner side of the elongated track 12 is slidably connected to the outer wall of the corresponding rotating shaft 9. This connection method not only ensures the smooth sliding of the rotating shaft 9 in the elongated track 12, but also allows the rotating shaft 9 to rotate flexibly along the predetermined trajectory. The box 1 has a U-shaped design, and the front side of multiple rotating shafts 9 is equipped with release devices 10. Release devices 10 and release devices 8 work together to form a complete safety protection. In an emergency, release devices 10 can act quickly.

[0031] Specifically, release devices 8 are carefully installed on both the left and right ends of the outer wall of the movable rod 5. As an important safety device, the release device 8 can act quickly under specific conditions and enhance the safety protection capability of the entire device. The spring 7, as another key component, has its other end attached to the left and right sides of the outer wall of the box 1. The elasticity of the spring 7 can provide stable support and reset function for the movable rod 5, ensuring that the movable rod 5 can remain smooth during sliding and can quickly return to the initial position when needed. The inner side of the elongated track 12 is slidably connected to the outer wall of the corresponding rotating shaft 9, thereby realizing precise control of the connecting rod 6 and the corresponding gate. Release devices 10 are set on the front side of multiple rotating shafts 9 to separate the rotating shafts 9 from the corresponding connecting parts, thereby ensuring the safety and reliability of the entire device and enabling the entire device to maintain stable performance and safety.

[0032] Working principle: The left-side head control 3 controls the closing circuit, and the right-side control 2 controls the opening circuit. Both ends have rollers 4 for easy movement. In use, the entire box 1 moves and the rollers 4 slide on the external track. The moving rod 5 of the left-side control 3 moves under pressure, driving the middle connecting rod 6 to move upward, thereby controlling the external switch to close. Similarly, when the box 1 continues to move, causing the moving rod 5 of the right-side control 2 to move to the corresponding position, the moving rod 5 of the right-side control 2 will also move under pressure, thereby opening the circuit. At this time, the left-side control 3 is reset by the spring 7. Therefore, its function is to provide protection against electric shock and leakage when there is leakage in the line or electric shock to a person. The leakage is amplified by the integrated circuit. When the set value is reached, the power is cut off within 0.1 seconds by the leakage trip device, thereby providing protection against electric shock and leakage.

[0033] 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.
