Description

Technical Field

[0001] The utility model belongs to the technical field of overload alarm devices, in particular to a novel circuit breaker overload alarm device. Background Art

[0002] A circuit breaker is an electrical protection device that closes a circuit under normal operating current and quickly opens it upon detecting an overload, short circuit, or other abnormal condition, protecting the circuit and connected electrical equipment. Circuit breakers offer multiple protection features, including short-circuit protection, overload protection, and undervoltage protection. For overload protection, a circuit breaker overload alarm is required.

[0003] Currently available circuit breaker overload alarms are safety devices used in power systems. They sound an alarm when a circuit is overloaded, rather than immediately shutting off power. This design is suitable for situations where a sudden power outage would cause greater losses, such as power lines for firefighting equipment. Overload alarms are typically used in conjunction with circuit breakers. They monitor the circuit current to determine if an overload is present and trigger an alarm when the current exceeds a preset threshold.

[0004] However, when installing the existing circuit breaker overload alarm device, a large number of screws are required for fixing the device. When the installation space is small, it is inconvenient for the user to install it, which is time-consuming and labor-intensive, thus affecting its use. Therefore, a new circuit breaker overload alarm device is proposed to address the above problems. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem raised in the background art, the present invention proposes a novel circuit breaker overload alarm device.

[0023] Specific examples are given below.

[0025] During operation, the external connecting block is installed to the position corresponding to the limiting slot 111 on the installation block 104, and then the user starts the electric motor 106, the electric motor 106 drives the bidirectional screw 107 to rotate, the bidirectional screw 107 drives the moving block 108 to move, the moving block 108 drives the connecting rod 109 to move, and the connecting rod 109 drives the limiting rod 110 to be inserted into the installation block 104 and the external connecting block, thereby installing and fixing the overload protection alarm 1, which is convenient for users to install and fix, saves time and effort, improves installation efficiency, and improves the practicality of the device; at the same time, the internal structure and working principle of the overload protection alarm 1 are the same as those of existing equipment. The structure of the external connection block is that a through hole is opened on a block, and the through hole has the same structure as the limiting slot 111, and both can be matched with the structure of the limiting card rod 110. The through hole and the limiting card slot 111 are adjusted to the same axial direction, and then the limiting card rod 110 is passed through the limiting card slot 111 and the through hole of the external connection block, so that the overload protection alarm 1 can be quickly installed.

[0026] It should be noted that the specific shape of the external connection block is not limited. It can be a C-shape that clamps the upper and lower sides of the installation block 104 at the same time, or it can be a single-sided structure with only one side in contact with the installation block 104. Its main feature is the through hole set to match the limiting card rod 110.

[0029] Further, such as Figure 1As shown, one side of the protective cover 3 is fixedly connected to a fixing block 4; the surface of the fixing block 4 is threadedly connected to a stud 401; the stud 401 is threadedly connected to the surface of the overload protection alarm 1; when working, the user rotates the stud 401; the stud 401 is connected to the overload protection alarm 1, and the protective cover 3 is fixed, thereby reducing the opening of the protective cover 3 and reducing the impact of the protective cover 3 on its protection.

[0030] Further, such as Figure 1 As shown, an observation window 5 is provided on the surface of the protective cover 3; transparent glass is provided inside the observation window 5; when working, the situation displayed on the overload protection alarm 1 in the protective cover 3 can be viewed through the observation window 5 to understand it.

[0032] Working principle: by making the external connecting block be stuck into the limiting card slot 111 on the installation block 104, and then the user starts the electric motor 106, the electric motor 106 drives the bidirectional screw 107 to rotate, the bidirectional screw 107 drives the moving block 108 to move, the moving block 108 drives the connecting rod 109 to move, and the connecting rod 109 drives the limiting card rod 110 to be stuck into the installation block 104 and the external connecting block, thereby installing and fixing the overload protection alarm 1, making it convenient for users to install and fix, saving time and effort, improving installation efficiency, and improving the practicality of the device; at the same time, the internal structure and working principle of the overload protection alarm 1 are the same as those of the existing equipment, and the external connecting block refers to a structure that cooperates with the installation block 109, and its structure refers to a through hole opened on a block, and then the installation block 109 is stuck in this hole, and the guide slide is driven by the moving block 108.
