A fixed buckle structure of a switch device

technical field

The present invention relates to the technical field of switchgear, in particular to a fixing buckle structure of a switchgear.

Background technique

The word switch is interpreted as turning on and off. It also refers to an electronic component that can open a circuit, interrupt current, or cause it to flow to other circuits. The most common switch is an electromechanical device that is operated by a human, in which one or more Electronic contact, the "closed" of the contact means that the electronic contact is turned on and allows current to flow; the "open" of the switch means that the electronic contact is not conducting to form an open circuit, which does not allow current to flow, and the existing switch During use, the switch handle and the fixed buckle in the switch are often rotated in the same direction during rotation, so that the handle cannot be retracted into the casing after the handle continues to rotate after the brake is opened.

Preferably, the side of the snap link away from the snap hole is embedded into the linkage groove.

Preferably, the handle rotating member is fixedly connected to the handle connecting rod through a first spring.

To sum up, due to the adoption of the above-mentioned technical solutions, the beneficial effects of the present invention are:

1. In the present invention, by installing the first spring, the elastic force of the first spring can fix the initial position of the handle rotating member and the handle connecting rod, and when the user toggles the handle rotating member to control the opening and closing of the device, the handle During the rotation of the rotating part, it will drive the buckle link to move through the linkage slot, pull the fixed buckle to rotate through the fixed buckle, and the fixed buckle rotates through the center of the fixed buckle. The rotation center of the fixed buckle is not concentric with the handle, and the handle rotates. After the device is opened, continue to rotate to retract the fixing buckle into the main body of the device.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Please refer to FIG. 1 to FIG. 4 , the present invention proposes a fixing buckle structure of a switch device. A fixing buckle structure of a switch device includes a device body 1 , a handle rotating member 2 and a fixing buckle 3 . The inner right side of the device body 1 is A handle rotating member 2 is embedded in the lower corner;

A rotating groove 201 is provided in the front middle of the handle rotating member 2, a first spring 203 is embedded in the interior of the rotating groove 201, a handle connecting rod 202 is embedded in the front middle of the first spring 203, and a card is provided in the lower left corner of the device main body 1. Hole 205, the snap link 4 is fixedly connected in the snap hole 205, the front of the handle link 202 is nested with a lock 6, the left side of the handle rotating part 2 is provided with a fixed buckle 3, and the middle of the rear end of the fixed buckle 3 is provided A linkage groove 301 is opened, and a fixed buckle 5 is fixedly connected to the upper right corner of the rear of the linkage groove 301 .

Further, the side of the snap link 4 away from the snap hole 205 is embedded into the linkage groove 301 , so that the rotation of the handle rotating member 2 drives the snap link 4 to rotate along the linkage slot 301 and drives the fixed buckle 3 to rotate while moving. The fixed buckle 3 will rotate through the fixed buckle 5, so that the rotation center of the fixed buckle 3 is not concentric with the handle rotating member 2.

Further, the handle rotating member 2 is fixedly connected to the handle connecting rod 202 through the first spring 203 , so that the initial position between the handle rotating member 2 and the handle connecting rod 202 is always maintained by the elastic force of the first spring 203 .

Working principle: When in use, the elastic force of the first spring 203 can fix the initial position of the handle rotating member 2 and the handle connecting rod 202, and when the user toggles the handle rotating member 2 to control the opening and closing of the device, the handle rotating member 2 During the rotation, the buckle link 4 is driven to move and pull the handle link 4 through the linkage groove 301, so that the fixed buckle 3 rotates through the fixed buckle 5, and when the fixed buckle 3 rotates, its rotation center is different from the handle rotating member 2. , and the handle rotating member 2 continues to rotate to retract the fixing buckle 3 into the device main body 1 after the switch is opened.

The embodiments of the present invention are presented for purposes of illustration and description, and are not intended to be exhaustive or to limit the invention to the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to better explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for the design of various embodiments with various modifications as are suited to the particular use.
