Description

Technical Field

[0001] The utility model relates to the technical field of switch appliances, in particular to a manual operation type driving breaker closing and opening device. Background Art

[0002] Many of the operating handles of the currently used breakers are straight-pulling handles, and when performing closing and opening operations, the trajectory of the handle is a straight line. Different application scenarios have different requirements for breakers. Considering various aspects such as convenient operation and safety, in some scenarios, a breaker with a rotary handle operation method must be used, and the trajectory of the rotary handle operation is an arc.

[0003] Therefore, in many cases, a rotary operation mechanism (closing and opening device) is externally installed on the handle of a general straight-pulling breaker, and the rotary operation mechanism is used to drive the handle of the straight-pulling breaker to act. By adopting this method, the original breaker does not need to be modified, and it can be made to have a rotary operation function to meet the requirements.

[0004] However, the existing handle operation mechanism has a complex structure, with many internal components and a large space occupation. Naturally, the complex structure also means high production costs and subsequent maintenance costs. Content of the Utility Model

[0005] The purpose of the utility model is to provide a manual operation type driving breaker closing and opening device.

[0006] The utility model has the advantages of simple structure and low cost.

[0007] The technical solution of the utility model: A manual operation type driving breaker closing and opening device includes a handle installed on a box body, a cam arranged in the box body and connected to the handle, and a slider arranged below the cam; the slider is driven by the cam to rotate, and a pair of push rods corresponding to the breaker handle are arranged below the slider; the slider includes a rotating end, a fixed end, and an installation part for installing the push rod; the fixed end is rotationally connected to the box body through a fixed rod, and the rotating end is slidably connected to the cam through a linkage rod; the slider rotates with the fixed rod as the axis.

[0008] In the aforementioned manual operation type driving breaker closing and opening device, a linkage groove corresponding to the linkage rod is opened on the rotating end, and the linkage groove includes a sliding groove and an installation groove; the linkage rod includes a connecting rod and a limiting block, and the diameter of the limiting block is larger than that of the connecting rod; the sliding groove corresponds to the connecting rod, and the installation groove corresponds to the limiting block.

[0009] In the aforementioned manual operation type driving breaker closing and opening device, a sleeve block is arranged on the push rod, and the sleeve block is in corresponding contact with the breaker handle; the push rods are correspondingly distributed on both sides of the breaker handle.

[0010] In the aforesaid manual drive circuit breaker closing and opening device, a handle seat for installing a cam is provided at the lower part of the handle, and the cam is fixedly connected with the handle seat through a fixing member.

[0011] In the aforesaid manual drive circuit breaker closing and opening device, a torsion spring connected to the box body is sleeved on the lower part of the fixed rod, and a detachable limit screw is provided at the lower end of the fixed rod; one end of the torsion spring abuts against the inner wall of the box body, and the other end abuts against the slider.

[0012] Compared with the prior art, the utility model includes a handle, a cam and a slider. The slider includes a rotating end and a fixed end, and is provided with a push rod corresponding to the circuit breaker handle. The fixed end is rotatably connected to the box body through a fixed rod, and the rotating end is interactively connected with the cam through a linkage rod. Thus, by rotating the handle, the cam can be driven to rotate, and the slider can be driven to rotate around the fixed rod as the axis. When the cam rotates, the push rod can push the circuit breaker handle to perform a linear motion, realizing the opening and closing actions;

[0013] The structure design of this application is simple and ingenious. Each component is connected in a detachable manner, and its production, processing and subsequent maintenance costs are relatively low and the maintenance is convenient.

[0014] Therefore, the utility model has the advantages of simple structure and low cost. Description of the Drawings
