Description

Technical Field

[0001] The utility model relates to the technical field of transfer switches, in particular to a control switch trigger mechanism for a dual-power automatic transfer switch. Background Art

[0002] Dual power automatic transfer switches are often used in conjunction with control switches. Control switches mostly use micro switches. Some control switches are used for closing indication, and some control switches are used for electrical interlocking.

[0003] In the prior art, there is a rotary control mechanism for a dual power switch disclosed in application number CN200920192875.0, which includes a micro switch, a rotating arm, a rotating disk and a rotating disk shaft fixedly arranged on the rotating disk. There are three micro switches, two of which cooperate with two groups of rotating arms to detect the working status of the rotating arms, and the other micro switch cooperates with the rotating disk to detect the working status of the rotating arm.

[0004] However, the rotating arm used to trigger the micro switch mentioned in the prior art triggers the micro switch by swinging the rotating arm, and the rotating arm is easy to detach from the switch, resulting in a large actual working error. In addition, the toggling of the micro switch is easy to impact the micro switch, causing the switch to move, resulting in less reliable triggering. Therefore, it is necessary to design a control switch trigger mechanism for a dual power automatic transfer switch. Utility Model Content

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0024] A control switch triggering mechanism for a dual-power automatic transfer switch, as Figures 1 to 5 shown, includes a housing 1, on which a control switch assembly 2 is fixedly installed. A trigger member 4 is arranged on one side of the control switch assembly 2. The trigger member 4 is slidably installed on the housing 1 and is used to touch the ejector rod 21 slidably arranged on the control switch assembly 2 to operate the switch operation of the control switch assembly 2.

[0025] Among them, the inside of the control switch assembly 2 is two control switch modules 23. The two control switch modules 23 are respectively located on both sides of the ejector rod 21. The movement of the ejector rod 21 controls the two control switch modules 23 simultaneously.

[0026] A driving mechanism 3 is arranged on the housing 1. The driving mechanism 3 includes a first rotating rod and a second rotating rod. Both the first rotating rod and the second rotating rod are rotatably connected to the housing 1. A energy storage spring is sleeved on the second rotating rod. The second rotating rod is slidably connected to the end of the first rotating rod.

[0027] A connecting rod 31 is rotatably connected to the first rotating rod. One end of the connecting rod 31 is movably connected to a driven member 32. An incomplete gear is fixedly arranged on one side of the driven member 32. A driving motor is fixedly installed on the housing 1. The output end of the driving motor is fixedly installed with a driving gear 33. The driving gear 33 meshes with the incomplete gear to control the rotation of the driven member 32 to drive the movement of the driving mechanism 3. When the first rotating rod rotates, it will push the trigger member 4 to translate and trigger the control switch assembly 2.

[0028] A cover body 5 is fixedly arranged on the housing 1 for protecting the driving mechanism 3. The control switch assembly 2 includes a base 22 and a gland 25. The gland 25 is snap-fitted with the base 22 to fix the two control switch modules 23. A reset compression spring 24 is fixedly arranged in the base 22 and between the two control switch modules 23. The ejector rod 21 is slidably installed between the gland 25 and the base 22, and one end of the ejector rod 21 is fixedly connected to the reset compression spring 24.

[0029] Side plates 11 are fixedly arranged on the housing 1 for limiting both ends of the control switch assembly 2. An installation block 12 is fixedly arranged on the housing 1 and on one side of the control switch assembly 2. The installation block 12 is located on the side of the control switch assembly 2 away from the ejector rod 21 to ensure the accurate and reliable positioning of the control switch assembly 2.

[0030] There are two sets of inclined plane structures at the contact position between the ejector rod 21 and the control switch module 23. When the ejector rod 21 moves, the contacts of the control switch module 23 are gradually pressed down until the control switch module 23 is disconnected; after the force on the ejector rod 21 is eliminated, the ejector rod 21 returns to its original position under the action of the return compression spring 24, and the control switch module 23 closes; after the gland 25 is positioned and matched with the base 22, the front and rear sets of buckle feet are fixed, and the left and right sides are misaligned and matched.

[0031] The working principle is as follows:

[0032] After the control switch assembly 2 is assembled, it is fixed between the side plate 11 and the mounting block 12, with the ejector rod 21 facing the actuating member 4. Then, the driving mechanism 3 is assembled and connected to the driven member 32 through the connecting rod 31. Under the action of the driving motor, through the meshing transmission of the driving gear 33 and the incomplete gear, the connecting rod 31 is driven to move, causing the driving mechanism 3 to move and work. When the driving mechanism 3 pushes the actuating member 4, the actuating member 4 moves to drive the ejector rod 21 to translate.

[0033] When the ejector rod 21 moves, the contacts of the control switch module 23 are gradually pressed down until the control switch module 23 is disconnected; when the driving mechanism 3 pushes the actuating member 4 to move in the reverse direction, at this time, after the force on the ejector rod 21 is eliminated, the ejector rod 21 returns to its original position under the action of the return compression spring 24, and the control switch module 23 closes. When the driving mechanism 3 works, the control switch assembly 2 is synchronously triggered.

[0034] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed.
