Problems solved by technology

[0003] The existing closing operation specifically drives the rotating shaft to rotate synchronously through the rotation of the handle to achieve closing, while the existing isolating switch realizes the reset effect through the torsion spring. During the closing process (that is, switching from the opening state to the closing state ), due to the rapid reset of the torsion spring, the operator has just opened the brake, and the rapid rotation of the handle is easy to hit the operator's hand. Affect the work of the entire line, causing major economic losses

Embodiment 1

[0054] Refer to attached Figure 1-13As shown, an isolating switch includes a housing 1 and a handle 6. The housing 1 includes an upper cover 7 and a base 8. The upper cover 7 and the base 8 are fixed through a detachable connection to form a fixed chamber, which is detachable here. The type connection is specifically fixed by bolts. The base 8 is specifically used for fixing components, and the upper cover 7 is used for closing the base 8 . In order for the operator to more intuitively observe the connection relationship between the movable contact 26 inside the housing 1 and the first static contact 11 and the second static contact 12, a transparent lens 71 is provided on the upper cover 7, and the transparent lens 71 It is located directly above the movable contact 11, and part of the structure of the first static contact 11 and the second static contact 12 can be observed. The transparent lens 71 is provided with a buckle 711 , and the upper cover 7 is provided with a sl...

Embodiment 2

[0072] Refer to attached Figure 14 As shown, the difference between Embodiment 2 and Embodiment 1 is that two tension springs 9 are also included, and a first fixing ring 66 is provided on the handle 6, and the first fixing ring 66 is specifically located at the center position of the handle 6 toward the inside. .

[0073] The side wall of the energy storage chamber near the handle 6 is provided with an annular groove 132, the annular groove 132 is provided with a fixing piece 91, and the two ends of the fixing piece 91 are respectively provided with a second fixing ring 911 and a third fixing ring 912, a tension spring 9 connects the first fixing ring 66 and the second fixing ring 911 , and another tension spring 9 connects the first fixing ring 66 and the third fixing ring 912 .

[0074] Through the setting of two extension springs 9, after the handle 6 is rotated, the handle 6 is reset to the middle due to the effect of the extension springs 9, so that the handle 6 is alw...

Abstract

The invention discloses an isolating switch, which comprises a housing and a handle. The housing is provided with a first static contact and a second static contact. The housing is provided with a rotating shaft, and the rotating shaft is provided with a moving contact. The handle is linked with the rotating shaft. Drive the rotating shaft to rotate to realize the connection or disconnection of the first static contact and the second static contact, wherein, one end of the rotating shaft is provided with a gap, the handle is provided with a connecting part, and the connecting part is provided with an annular cavity, and the side of the annular cavity is A linkage part is provided on the wall, the area of ​​the linkage part is smaller than the area of ​​the notch, and the rotating shaft extends into the annular cavity, so that the two sides of the notch are located on the movement track of the linkage part, and the linkage part and the side of the notch are offset to realize the rotation of the rotating shaft; The invention has the characteristics of stable structure, slowing down of the rotation speed of the handle, lower cost, more convenient installation, and small space occupied by the structure.

Description

technical field [0001] The invention relates to an isolating switch. Background technique [0002] The isolating switch is a switching device that is mainly used to "isolate power supply, switch operation, connect and cut off small current circuits", and has no arc extinguishing function. When the isolating switch is in the off position, there is an insulation distance between the contacts that meets the specified requirements and an obvious disconnection mark; current switching device. [0003] The existing closing operation specifically drives the rotating shaft to rotate synchronously through the rotation of the handle to achieve closing, while the existing isolating switch realizes the reset effect through the torsion spring. During the closing process (that is, switching from the opening state to the closing state ), due to the rapid reset of the torsion spring, the operator has just opened the brake, and the rapid rotation of the handle is easy to hit the operator's ...
