Detailed description of the invention
Fig. 1 is the structural schematic diagram of an embodiment of the present invention；
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginningSame or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginsengThe embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and should not be understood as to the utility modelLimitation.
If Fig. 1 to 2 show the embodiments of the present invention structural schematic diagram, which includes pressingButton mechanism 1, button mechanism 1 pass through high voltage cabinet door and are arranged and can move back and forth on high voltage cabinet door thickness direction through pressing；PointBrake mechanism 2, brake separating mechanism 2 are located at the triggering end of button mechanism 1, and triggering end controls separating brake when the press-side of push button mechanism 1Mechanism 2 is towards breaker direction movement in high-voltage board to trigger breaker disconnection；Brake separating mechanism 2 includes bracket 21 and follower lever22, bracket 21 is connected with cabinet door and limits moving radially for follower lever 22, and follower lever 22 can be pushed by button mechanism 1 along follower leverThe movement of 22 axial directions and breaker contacts simultaneously trigger its disconnection, and follower lever 22 passes through elastomeric element and bracket 21 in axis directionConnection, follower lever 22 can reset under elastomeric element effect when the press-side of release button mechanism 1.When push button mechanism 1, pressTriggering end of the button mechanism 1 in cabinet door resists follower lever 22 to breaker movement, and the other end triggering breaker of follower lever 22 is disconnectedIt opens, in release button mechanism 1, under the action of elastomeric element, follower lever 22 resets, and promoting button mechanism 1 resets.
Elastomeric element uses spring 25 as a preferred method, and spring 25 is set in outside follower lever 22, and spring 25 is closeOne end of button mechanism 1 and follower lever 22 are fixed, and the other end and bracket 21 are fixed.
In the present embodiment, 1 periphery of button mechanism is provided with the knob 3 that can be rotated around 1 circumferencial direction of button mechanism, bracket 21One end and cabinet door be rotatablely connected, knob 3 is connect with the one end fits of bracket 21 so that the other end of bracket 21 can be revolved in knob 3Turn to rotate under driving around one end of bracket 21.In the normal state, brake separating mechanism 2 abuts cabinet door, when being in an emergency, rotationKnob 3 rotates the other end of brake separating mechanism 2, when follower lever 22 is aligned with the trigger switch of breaker, by lower buttonMechanism 1, when follower lever 22 trigger breaker disconnect, it is this design so that brake separating mechanism 2 normal state against cabinet door will not shadowComponents' placement in cabinet is rung, inspection operation will not be influenced, it is easy to use.
During rotation knob 3, it is directed at follower lever 22 quick and precisely with breaker trigger switch, is rotatingDuring knob 3, when follower lever 22 is directed at breaker trigger switch, button mechanism 1 is located at the intracorporal one end of cabinet and follower lever22 corresponding ends just offset, and can not continue to rotate knob 3, this ingenious in design, and can in case of emergency, fast and accuratelyCut-off breaker.In order to when making brake separating mechanism 2 in close proximity to cabinet door button mechanism 1 press after be also capable of resetting, in 1 housing of button mechanismEquipped with pressure spring 11, for pressure spring 11 by cabinet door inner wall one end and the axially opposing fixation of knob 3, the other end and button mechanism 1 are axially opposingIt is fixed.
In the present embodiment, bracket 21 and cabinet door junction are provided with torsional spring 23, in this way when unclamping knob 3, brake separating mechanism 2It can automatically reset to against cabinet door, structure is simple and convenient to operate.
In the present embodiment, the one end of knob 3 in cabinet door is fixedly installed U-shaped board 31, and bracket 21 is close to button mechanism 1 oneEnd is vertically provided with the first pin 211, and a foot of U-shaped board 31 is horizontally arranged with the second pin 311, the first pin 211 and secondPin 311 is connected by double end hanging buckle 24, and when rotating knob 3, U-shaped board 31 is rotated, thus drive double end hanging buckle 24 mobile, double endHanging buckle 24 drives bracket 21 to rotate.This design is very ingenious, and structure is very simple, while using U-shaped board 31, U-shapedRound end one end is not easy to contact with other component when plate 31 rotates, and saves the arrangement space of brake separating mechanism entirety.
In the present embodiment, in order to make brake separating mechanism 2 adapt to the high-voltage board of different size, the length of follower lever 22 is adjustableSection.Specifically, follower lever 22 includes the second bar being set in the first bar 221 in the first bar 221 and one end of hollow structure222, the first bar 221 is provided with nut far from one end of button mechanism 1, and the second bar 222 is provided with outer close to one end of the first barScrew thread, nut and external screw thread cooperate to adjust the length that the second bar 222 protrudes into the first bar 221.Accidental shock in order to prevent, reallyElectrical Safety is protected, one end that follower lever 22 is used to trigger breaker trigger switch, which is adopted, to be made from an insulative material, such as rubber etc..
