Embodiment
With reference to Fig. 1.Fulcrum post 14 is positioned at upper encloser wall 12 places of installation switchgear 10, and this fulcrum post 14 vertically is placed in upper encloser wall 12 places highlightedly.Also see the back working face 16,18 of the installation switchgear 10 that has bolt splicing ear 20.
Be mounted with perforate 22 in upper encloser wall 12, this perforate 22 is passed (seeing Fig. 2 a-c equally) by the pin projection 24 of control pin 26.In the diagrammatic sketch according to Fig. 1, control pin 26 is arranged in its unlocked position.Therefore, pin projection 24 degree like this ground stretch out from upper encloser wall 12, that is, make pin projection 24 turning handle 28 that is placed on the fulcrum post 14 (can be seen Fig. 3, Fig. 4 and Fig. 2 b) remain in its dropout position, as what further also will explain below.
The projection 30 of pawl lever 32 abuts in the cylinder of the cylindrical base 34 of control pin 26
The place.Thus, pawl lever 32 remains in its released state in the unlocked position according to the control pin 26 of Fig. 1, be arranged in thus installation switchgear inner and herein the detent mechanism of unshowned switch lock remain on its released state.
Referring now to Fig. 2 a-c.These figure with schematic diagram shown control pin 26 and pawl lever 32 and turning handle 28 on-position (Fig. 2 a), interaction in dropout position (Fig. 2 b) and the open position (Fig. 2 c).
Turning handle 28 is placed into upper encloser wall 12 places.Turning handle 28 illustrates with vertical view on the top of Fig. 2 a-c, and illustrates with the longitudinal cross-section in the bottom of Fig. 2 a-c.Turning handle 28 has the top section 42 and the handle section 44 of sub-circular.
Side towards the turning handle 28 of upper encloser wall 12 has holding tank 46, and this holding tank 46 is so arranged, that is, make this holding tank 46 can hold the pin projection 24 of control pin 26.When turning handle 28 when its on-position rotates to its open position, the arrow P in Fig. 2 a-c and Fig. 3 and Fig. 4 is represented direction of rotation.Form the boundary of holding tank 46 on the right side in Fig. 2 a-c by the control inclined-plane 50 of beveled, this boundary stretches towards the outside 49 of the turning handle 28 of case wall 12 always from the inboard 51 of holding tank 46, almost to the height of case wall 12, that is, stretch in the mode opposite with direction of arrow P.On direction of arrow P, observe, before control inclined-plane 50, promptly in Fig. 2 a-c in the left side on control inclined-plane 50, device for clamping 48 stretches out in the mode of pointing to upper encloser wall 12 vertically downward from inboard 51 beginning of holding tank 46.This device for clamping 48 shown in Fig. 2 a-c is being wall and so design, promptly, make and (to see that Fig. 2 is a) when its open position moves from its on-position when turning handle 24, this device for clamping 48 can block with pin projection 24, and turning handle 28 is fixed in its dropout position according to Fig. 2 b by pin projection 24.
As Fig. 3 or shown in Figure 4, control inclined-plane 50 stretches as plane inclined in the fringe region inside of circular top section 42.More clear for view, the displacement that turning handle 28 longitdinal cross-section diagram during transition between on-position, dropout position and open position is shown in the bottom of Fig. 2 a-c is depicted as the lateral displacement that is parallel to upper encloser wall 12.Will be understood that,, on function, realize identical effect if make turning handle 28 around fulcrum post 14 rotations.
In the diagram, turning handle 28 is loaded by being inserted on the direction of helical spring (being extruded with the side leg (not shown in Fig. 3) that tangentially stretches at a helical spring end place) at its open position in the top section 42 by cylindrical spring 25 and in according to the form of implementation of Fig. 3 in the bottom of Fig. 2 a-c.Other details about the use on supporting, layout and the function of helical spring in turning handle 28 sees also the file DE 20214578U1 that has mentioned.
In the on-position according to Fig. 2 a, the detent mechanism of switch lock ends lock and switch lock and therefore switchgear connection.Pawl lever 32 is pressed against ending in the lock state shown in Fig. 2 a by ratchet spring 52.Not shown herein switch lock and pawl lever 32 are connected with switch lock.
The power that acts on the spring 25 on the turning handle 28 is passed through known in principle structural measure by locking in on-state, thereby turning handle 28 remains in its on-position, this on-position is shown to the operator by the handle section 44 that is directed upwards towards, and sees the top of Fig. 2 a.
When take place threading off, the detent mechanism of unlock switch lock in short time, the power that makes pawl lever overcome ratchet spring 52 thus is brought in its released state.In released state, pawl lever 32 release control pins 26, thus make the control pin owing to the power that is applied thereon by spring 56 can upwards quickened on the direction of upper encloser wall 12.
Simultaneously, remove the power that acts on the spring 25 on the turning handle 28, make turning handle 28 on the direction of its open position, be loaded and be placed in the motion thus towards this place by another mechanism (not shown herein) that is connected with detent mechanism.Thus, the perforate of holding tank 46 arrives in the zone of the perforate 22 in the case wall 12.
Because the little quality of control pin 26 moves upward control pin 26 very apace under the influence that applies power thereon by spring 56.Moving upward of control pin 26 collides upper encloser wall 12 and locking by flange 40.The control pin has reached its unlocked position now, in this unlocked position, gives prominence to above upper encloser wall 12 to pin projection 24 degree like this, that is, pin projection 24 can be in device for clamping 48 engage and be clamped in the device for clamping 48.Therefore, this continuation campaign that holds for turning handle 28 is to hinder.
As Fig. 2 b further illustrated, in the unlocked position of control pin 26, matrix 34 was so upwards pushed to degree, that is, make matrix because its bigger diameter can make pawl lever 32 remain in its unlocked position.Thus, control pin 26 prevents that detent mechanism from may end lock once more.
In order to connect switching mechanism once more, the control pin must be brought to it once more to be ended in the lock position.For this reason, the operator must make turning handle 28 from continuing moving towards the direction of open position according to the dropout position of Fig. 2 b.At this, the operator must overcome the power of holding, thereby pin projection 24 can be unclamped from device for clamping 48, and the pin projection discharges turning handle 28 more then.When turning handle 28 continued rotation, control pin 26 was pressed in the inside of switchgear case again by control inclined-plane 50, reached approximate concordant with upper encloser wall 12 up to control pin 26.
In this position, the matrix 34 of control pin 26 is positioned under the projection 30 of pawl lever 32 once more.Therefore, pawl lever 32 is released once more and can arrives it once more by the power of ratchet spring 52 and ends in the lock state, thereby makes detent mechanism end lock once more.
In the open position according to Fig. 2 c, the control pin is pushed downwards and is remained on it by the part of the bottom side 49 of the turning handle 28 that is connected in control 50 places, inclined-plane and ends in the lock position.The projection 30 of pawl lever 32 is left (freikommen) convex shoulder 54 once more, and the power of control pin 26 can not be applied on the pawl lever 32 thus.
Can say now, detent mechanism be put got back to it and end in the lock state; Therefore this open position of turning handle 28 is also referred to as reset mode.
When only being locked, detent mechanism from reset mode or off-state, can make contact assembly pass through switch lock closure once more in the on-state now by turning handle 28 is rotated to.
Fig. 3 has shown the way of realization according to device for clamping 48 of the present invention.This device for clamping 48 forms by fixing stop part 481.This stop part 481 is the forming sections at 51 places, inboard of holding tank 46.This forming section is similar to has the shape of cylindrical base (Klotz).Cylinder on the side direction of this base extends inward in the holding tank 46 and forms the first interior boundary of holding tank 46.Form another border, lateral of holding tanks 46 by flexibly spring-like wall section 482 in the mode relative with this first interior boundary.This wall section 482 is clamping the outer edge that the position is formed into top section 42.This wall section 482 is flexibly inwardly pressed to stop part 481 with the form of one-sided flexibly clamped beam.Between stop part 481 and pressing element (wall section 482), form opposite reduce gradually, the guiding channel that is used for pin projection 24 in this way with direction of arrow P.This guiding channel works the space as being used for holding of pin projection.In the porch of this guiding channel, its perforate cross section is greater than the external diameter of pin projection 24, holds in the space 483 thereby this pin projection 24 is directed in funnel shaped mode.Degree like this ground reduces gradually towards the end in the perforate cross section,, makes its external diameter less than pin projection 24 that is.Then, spring-like ground flexibly tightens pin projection 24 between stop part 481 and pressing element 482.The continuing to rotatablely move of turning handle 28 braked by holding.This braking is also supported by projection 484, and this projection 484 is formed into stop part 481 places near the fastening part 485 that holds the exit in space in infundibulate.Projection 484 produces by the shaping of another columniform main body herein.Therefore, produce the backstop seamed edge that is used for the pin projection, this backstop seamed edge causes turning handle 28 to continue the reliable braking of motion.
But when turning handle is taken efforts when continuing rotation by the operator, then pin projection 24 slides past the backstop seamed edge of projection 484, and outwards pushes at this and to press wall 482.Control pin 26 leave once more and when turning handle 28 continues rotation by being pressed downwards once more, as recited above with control inclined-plane 50 that direction of rotation P connects on the contrary.
The turning handle 28 that has device for clamping advantageously is implemented as single die casting.
Fig. 4 shows another the possible form of implementation that is used for device for clamping 48.Stop part 481 is not embodied as solid as shown in Figure 3 herein, but is embodied as fixing stop wall 486.The side of stop wall 486 has bend, bends to the inside convex of this bend to hold in the space.Therefore, form the funnel shaped holding hole that is similar to according to the form of creeve by stop wall 486 and elastic wall 482.
Another operational feasibility that can imagine is that same stop wall is configured to flexibly spring-like.
