Description

Technical Field

[0001] This utility model relates to a manual operating device for a multi-position padlock, belonging to the field of low-voltage electrical installation technology. Background Technology

[0002] In the power system operation and maintenance system, low-voltage electrical appliances, as core components of line control, protection, and distribution, directly determine the reliability of the entire power network through their operational stability and safety. This also relates to the personal safety of maintenance personnel and the normal operation of downstream electrical equipment. With the continuous iteration of low-voltage electrical appliance technology, line installation and operation management have placed more stringent demands on operational safety and fault identifiability. Among these, the design of the operating handle function of the circuit breaker manual operating mechanism on the switchgear has become one of the key aspects of ensuring the safe operation of the line.

[0003] As the core component for line switching control and fault protection, the circuit breaker has two working states, opening and closing, which correspond to different scenario requirements. It needs to be protected against misoperation through a padlock mechanism.

[0004] When the line is in normal operation, the circuit breaker needs to remain closed to provide continuous power. Locking the operating handle to the closed position can effectively prevent accidental tripping due to human error. Accidental tripping can cause power outages and shutdowns of downstream equipment, leading to production disruptions or inconvenience. It can also damage sensitive equipment (such as precision instruments and motors) due to sudden power outages, and even trigger cascading problems such as localized voltage fluctuations in the power grid.

[0005] When a line needs inspection, maintenance, or equipment replacement, the circuit breaker must be switched to the open position to cut off the power supply and ensure that the maintenance area is de-energized. At this time, the operating handle should be locked in the open position to prevent unauthorized personnel from accidentally closing the circuit breaker. Accidental closing would directly connect a live line to the maintenance area, easily leading to electric shock or injury to maintenance personnel, or causing serious safety accidents such as short circuits or fires due to current surges.

[0006] Furthermore, when the circuit breaker is in the closed and latched state, if the circuit breaker trips due to overload, short circuit, or other faults (i.e., the circuit breaker automatically disconnects to protect the line), the operating handle must reliably indicate the tripping status. This function helps maintenance personnel quickly determine whether a fault has occurred on the line by observing the handle position, avoiding misjudging the line's operating status due to the inability to identify the tripping status, and providing crucial information for fault diagnosis and maintenance.

[0007] Currently, the existing manual operating mechanism mounting base for circuit breakers clearly has the aforementioned technical defects and cannot meet the above safety requirements. Utility Model Content

[0008] To solve the above problems, this utility model provides a manual operating device for a multi-position padlock, comprising: The base has a mounting hole on its upper surface and a first base groove and a second base groove around the mounting hole. The first base groove and the second base groove are respectively connected to the outer periphery of the mounting hole and the edge of the upper surface of the base in different directions. A rotary mechanism is disposed within the mounting hole of the base; A padlock is located above the rotary mechanism and is movably fitted into the first base groove or the second base groove. When the padlock is fitted into the first base groove, the padlock is stretched along the first base groove to achieve the open position padlock. When the padlock is fitted into the second base groove, the padlock is stretched along the second base groove to achieve the closed position padlock. The handle is attached to the top of the padlock and fits into the mounting hole; When the circuit breaker is in the closed padlock state, if the circuit breaker trips, the handle will drive the padlock and the slewing mechanism to rotate counterclockwise in the second base groove to ensure that the padlock state remains unchanged.

[0009] Furthermore, the upper surface of the base is a rectangular structure with four sides on its outer perimeter, the four sides including two first pairs of opposite sides and two second pairs of sides perpendicularly adjacent to the first pairs of sides.

[0010] Furthermore, the first base groove is a strip structure, with one end connected to the mounting hole and the other end vertically connected to the first pair of sides of the upper surface of the base.

[0011] Furthermore, the second base groove is a fan-shaped structure, with one end connected to the mounting hole and the other end connected to the second side and the right angle formed by the second side and the first side connected to the first base groove. The extension lines of the two sides of the second base groove can form an acute angle.

[0012] Furthermore, the included angle formed by the extension lines of the two sides of the second base groove is 45 degrees.

[0013] Furthermore, the base has an annular rib around the mounting hole, which supports the handle and restricts the handle from passing through the mounting hole.

[0014] Furthermore, the base has multiple positioning grooves above the annular ribs, and the positioning grooves are semi-circular notch-shaped structures.

[0015] Furthermore, a handle fixing seat is connected to the bottom of the base, and the handle fixing seat has a wedge-shaped surface.

[0016] Furthermore, the bottom of the base is connected to the handle fixing seat via a base cover.

[0017] Furthermore, the padlock component has a waist hole that can accommodate φ5-φ8 padlocks.

[0018] The beneficial effects of this utility model are: This utility model forms a device specifically for manually operating multi-position padlocks by combining a base, a rotating mechanism, a padlock component, and a handle. First and second base grooves are provided on the base to cooperate with the padlock component, enabling multi-directional padlock extension. This allows for padlocking in both the open and closed positions. Furthermore, when the circuit breaker trips after being locked in the closed position, the circuit breaker provides a tripping indication in conjunction with the tripping action. The operating handle indicates the open position horizontally and the closed position vertically. In addition, it limits the overtravel of the operating handle to prevent damage to the operating handle on the circuit breaker. Attached Figure Description

[0023] This utility model provides a manual operating device for a multi-position padlock. Figures 1-2 The example includes, from top to bottom, the handle 4, padlock 3, base 1, rotating mechanism 2, base cover 5, and handle fixing seat 6.

[0024] exist Figure 3 In the example, the base 1 is an irregular structure composed of rectangular blocks and wedge-shaped blocks. Its upper surface (the upper surface of the rectangular block portion) has mounting holes, and a first base groove 11 and a second base groove 12 are arranged around the mounting holes. The upper surface of the base is also a rectangular structure with four sides, including two opposing first pairs of sides and two perpendicular second pairs of sides. The two first pairs of sides are parallel and perpendicular to the two second pairs of sides. Figure 3 In the example, the two pairs of sides perpendicular to the connection direction between the handle 4 and the base 1 are the second pair of sides, and the other two are the first pair of sides.

[0025] In some embodiments, mounting holes can also be provided near the mounting holes. The mounting holes are round holes and are distributed at any of the four corners of the upper surface of the base 1. They are used to cooperate with the handle 4 above. The handle 4 and the base 1 can be connected by fasteners to form a stable connection.

[0026] In some embodiments, the first base groove 11 and the second base groove 12 are respectively connected to the outer periphery of the mounting hole and the edge of the upper surface of the base in different directions; Figure 3In the example, the first base groove 11 is a strip structure, with one end connected to the mounting hole and the other end perpendicularly connected to the first pair of sides on the upper surface of the base 1. The first base groove 11 can form a strip channel along the direction of the second pair of sides, connecting the mounting hole and the first pair of sides, allowing the padlock 3 to move through. The second base groove is a fan-shaped structure, with one end connected to the mounting hole and the other end connected to the second side and the right angle formed by the second side and the first side connected to the first base groove. The extension lines of the two sides of the second base groove can form an acute angle. The second base groove 12 can form a fan-shaped channel transitioning from the direction of the first pair of sides to the direction of the angle between the first pair of sides and the second pair of sides. With this configuration, the padlock 3 can move within the acute arc area of ​​this fan-shaped channel.

[0027] exist Figure 2 In the example, the rotary mechanism 2 is disposed in the mounting hole of the base 1; the rotary mechanism 2 is a clamp capable of rotation, and its gripper part can cooperate with the handle 4.

[0028] exist Figures 2-3 In the example, the padlock 3 has a π-shaped structure with a protrusion at its bottom that can engage with the first base groove 11 and the second base groove 12. This protrusion can slide within either the first base groove 11 or the second base groove 12. When the padlock 3 engages with the first base groove 11, it is pulled outward along the first base groove 11 towards the second opposite side to achieve the open position padlock. When the padlock 3 engages with the second base groove, it is pulled outward along the second base groove 12 towards the first opposite side to achieve the closed position padlock. Additionally, the padlock 3 also has a waist hole that can engage with φ5-φ8 padlocks.

[0029] Preferably, the angle formed by the extension lines of the two sides of the second base groove 12 is 45 degrees, so that the padlock 3 can rotate in a 45-degree direction.

[0030] exist Figure 4 In the example, the base 1 has an annular rib 13 around the mounting hole inside, which supports the handle 4 and restricts the handle 4 from passing through the mounting hole. Multiple positioning grooves 14 are provided above the annular rib 13 inside the base 1. The positioning grooves 14 are semi-circular notches. The arrangement of the annular rib 13 and the positioning grooves 14 ensures that the assembled handle 4 can reliably stop in both horizontal and vertical positions. Simultaneously, the limiting design of the annular rib 13 allows for a larger operating angle of the handle 4, which is beneficial for completing the circuit breaker's re-triggering and closing functions.

[0031] exist Figures 1-2 In the example, the handle 4 is connected above the padlock 3 and fits into the mounting hole.

[0032] In the closed padlock state, if the circuit breaker trips, the handle 4 will drive the padlock 3 and the rotation mechanism 2 to rotate counterclockwise in the second base groove 12, ensuring that the padlock state remains unchanged, and also ensuring that the circuit breaker fault trip position indication can be reliably realized.

[0033] In some embodiments, the handle fixing seat 6 has a wedge-shaped surface and is an irregular structure formed by connecting a rectangular block and a wedge-shaped block. The bottom of the base 1 is connected to the handle fixing seat 6 via a base cover 5.

[0034] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
