[0001] This utility model relates to the field of monitoring equipment technology, specifically to a circuit breaker mechanical characteristic acquisition terminal. Background Technology

[0002] The mechanical characteristics of a circuit breaker are a key indicator of its performance and reliability, encompassing several important aspects. The opening and closing time determines the timeliness of the circuit breaker's control over the circuit's on / off state. Speed ​​characteristics, including the initial opening speed and the initial closing speed, affect the breaking capacity and arc extinguishing effect. Mechanical life reflects the reliability and durability of the circuit breaker's mechanical structure. Vibration and shock, on the other hand, can affect the stability of the circuit breaker's own structure and surrounding equipment.

[0003] The circuit breaker mechanical characteristic acquisition terminal needs to be installed inside the electrical box during operation. The usual fixing method is bolt fixing, that is, fixing the circuit breaker mechanical characteristic acquisition terminal inside the electrical box by bolt fixing. However, the bolt fixing method has great positional limitations. The bolt holes need to be perfectly aligned to make the bolt connection, which is not convenient to use. Therefore, the circuit breaker mechanical characteristic acquisition terminal is proposed. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments, highlighting the above and other technical features and advantages of the present invention. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.

[0025] Example:

[0026] like Figures 1-5 As shown, this utility model provides a circuit breaker mechanical characteristic acquisition terminal, including a mechanical characteristic acquisition terminal body 1. The front end of the mechanical characteristic acquisition terminal body 1 is connected to a mechanical characteristic acquisition terminal outer cover plate 2 via a rotating shaft. The back of the mechanical characteristic acquisition terminal body 1 is provided with a clamping and fixing assembly 3 for locking and fixing. The clamping and fixing assembly 3 includes a limiting slide rail 31, a sliding push plate 32, a clamping part 33, and a reset spring 34. Two sets of limiting slide rails 31 are respectively arranged on both sides of the back of the mechanical characteristic acquisition terminal body 1. Two sets of sliding push plates 32 are respectively arranged inside the two sets of limiting slide rails 31. The two sets of limiting slide rails 31 are respectively arranged on the outer side between the opposite ends of the two sets of sliding push plates 32. The reset spring 34 is arranged on the inner side between the opposite ends of the two sets of sliding push plates 32.

[0027] Under the elastic force of the reset spring 34, the two sets of sliding push plates 32 move laterally along the limit slide rail 31. The two sets of sliding push plates 32 move laterally and pull the two sets of clamping parts 33 to move in opposite directions and clamp them in the metal track.

[0028] Two sets of sliding push plates 32 are symmetrically arranged. The ends of both sets of sliding push plates 32 are provided with bolt fixing holes for bolt fixing. After the sliding push plates 32 are fixed in their positions, they can be further fixed to the metal track through the bolt fixing holes at the ends of the sliding push plates 32, thereby further improving the fixing stability.

[0029] The clamping part 33 includes a movable clamping plate 331, a support rod 332, a redundant rod 333, a hook 334, and a spring 335;

[0030] The movable clamping plate 331 is disposed between two sets of sliding push plates 32. Two sets of support rods 332 are respectively installed at both ends of the movable clamping plate 331 via rotating shafts. A redundant rod 333 is disposed inside the support rod 332 and can slide relative to the movable clamping plate 331. A hook 334 is disposed at the end of the redundant rod 333. When the two sets of sliding push plates 32 move in opposite directions, the two sets of sliding push plates 32 can push the support rods 332 on both sides of one set of movable clamping plates 331. Under the push of the sliding push plates 32, the two sets of support rods 332 push the movable clamping plate 331 so that the movable clamping plate 331 moves toward the edge of the mechanical characteristic acquisition terminal body 1. The two sets of movable clamping plates 331 move away from each other during the movement. The hooks 334 inside the movable clamping plate 331 move synchronously with the movable clamping plate 331 and the two sets of hooks 334 open.

[0031] The hook 334 has a folded design and a rubber pad is attached to the inner wall of the hook 334. The two sets of hooks 334 form a clamping and fixing space. When clamping, the upper and lower sets of hooks 334 can be clamped on the upper and lower sides of the metal track respectively. During the clamping process, the rubber pad on the inner wall of the hook 334 can further increase the contact friction, thereby ensuring clamping stability.

[0032] The clamping part 33 also includes a spring 335, which is sleeved on the outside of the redundant rod 333. The two ends of the spring 335 abut against the inner wall of the redundant rod 333 and the movable clamping plate 331, respectively. Under the elastic force of the spring 335, the redundant rod 333 is housed in the support rod 332. When the installation of the mechanical characteristic acquisition terminal body 1 is obstructed, the redundant rod 333 can be moved outward along the movable clamping plate 331 by pulling the redundant rod 333, providing additional installation space. The outward movement of the movable clamping plate 331 can push the spring 335 to deform under pressure. The deformed spring 335 provides a reaction force to the redundant rod 333, so that the hook 334 receives sufficient reverse force while connecting with the metal rail. Under the reverse force, the mechanical characteristic acquisition terminal body 1 can be tightly attached to the surface of the obstruction, thereby further improving the stability during the installation process.

[0033] The reset spring 34 is provided in several groups, and each group of reset spring 34 is arc-shaped. The reset spring 34 is divided into two groups and is set between two groups of sliding push plates 32 facing each other. When the reset spring 34 is normally unfolded, the two groups of sliding push plates 32 move in opposite directions under the pushing action of the reset spring 34. The sliding push plates 32 moving in opposite directions pull the two groups of clamping parts 33 to move in opposite directions. The clamping parts 33 moving in opposite directions can clamp outside the metal track. When the clamping parts 33 can no longer move, the clamping action is completed.

[0034] The clamping and fixing assembly 3 also includes a protective cover plate 35, which covers the space between the two sets of limiting slide rails 31. The protective cover plate 35 shields the reset spring 34 between the two sets of sliding push plates 32. Under the shielding effect of the protective cover plate 35, the reset spring 34 will not directly contact the metal track inside the electrical box, thus avoiding the metal track and debris inside the electrical box from affecting the normal bending deformation of the reset spring 34.

[0035] The length of the sliding push plate 32 is longer than the length of the limiting slide rail 31, and the distance between the two sets of sliding push plates 32 is greater than the width of the mechanical characteristic acquisition terminal body 1. After the setting position of the sliding push plate 32 is fixed, the setting position of the limiting slide rail 31 relative to the sliding push plate 32 can be adjusted by pushing the mechanical characteristic acquisition terminal body 1. This allows for further adjustment of the setting position of the mechanical characteristic acquisition terminal body 1 after the setting position of the clamping and fixing component 3 is determined, thereby improving the installation adaptability of the device.

[0036] In use, the sliding push plates 32 are pushed to move in opposite directions. The two sets of sliding push plates 32 respectively push the support rods 332 on both sides of a set of movable clamping plates 331. Under the push of the sliding push plates 32, the two sets of support rods 332 push the movable clamping plates 331, causing the movable clamping plates 331 to move towards the edge of the mechanical characteristic acquisition terminal body 1. During the movement, the two sets of movable clamping plates 331 move away from each other. The hooks 334 inside the movable clamping plates 331 move synchronously with the movable clamping plates 331. During this process, the reset spring 34 deforms and stores force, and the two sets of hooks 334 open to form a clamp. The fixed space is moved so that the mechanical characteristic acquisition terminal body 1 is clamped and fixed outside the metal track. The push on the sliding push plate 32 is released, the reset spring 34 is reset, and the sliding push plate 32 moves backward under the push of the reset spring 34. The two sets of support rods 332 pull the movable clamping plate 331 so that the movable clamping plate 331 moves toward the center of the mechanical characteristic acquisition terminal body 1. The two sets of movable clamping plates 331 move closer to each other during the movement. The hooks 334 inside the movable clamping plate 331 move synchronously with the movable clamping plate 331 and are clamped outside the metal track.

[0037] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
