Technical field
The present invention relates to a kind of shrinking connecting-rod device, particularly relate to a kind of low-voltage distribution cabinet panel shrinking connecting-rod device, be applied in the low voltage switchgear.
Background technology
Tapping unit device in the domestic low pressure pull-out type voltage switchgear has connection, test, three operating positions of disconnection; And mainly be artificial drawing formula operation to the mode of operation of tapping unit device; Connecting, test, needing switch cabinet panel to remain on closed condition when breaking off three position operation, to reach the protection of coal dust, dust in the environment to external world.And be a rigid links between handle outside the panel in the at present domestic pull-out type voltage switchgear and the mechanism part in the cabin; Make the tapping unit device connect, test, panel closure fully when breaking off three operating positions; Therefore coal dust, dust can get into the pollution that causes in the panel electric equipment in the cabin in the external environment; Influenced its operate as normal, serious meeting causes the generation of operating irregularity.
Summary of the invention
The purpose of this invention is to provide a kind of low-voltage distribution cabinet panel shrinking connecting-rod device; With the tapping unit that reaches switch cubicle connect, test, panel can be closed fully when breaking off three operating positions; Thereby prevent the coal dust in the external environment, the entering of dust, satisfy the production requirement of degree of protection that electric equipment reaches.
Technical scheme of the present invention is:
A kind of low-voltage distribution cabinet panel shrinking connecting-rod device comprises control piece and linkage component; Said linkage component comprise one have an inner chamber outer bar, the interior bar and that inserts outer bar inner chamber be arranged on the prepressing elastic in the outer bar inner chamber; The bar wall of described outer bar is provided with an axial elongated slot; Said control piece is fixedly arranged on the interior bar that stretches in the outer bar; When bar was made telescopic displacement in the inner chamber of bar outside in making, control piece can be fastened on the elongated slot of said outer bar.
Said control piece is a pin, and the said interior bar that stretches in the outer bar is provided with a blind hole, said pin with the blind hole on the interior interior bar of the outer bar that stretches into closely cooperate and be fixed together.
Said control piece is a screw, and the said interior bar that stretches in the outer bar is provided with a screw, and the screw on said screw and the said interior bar that stretches in the outer bar is spirally connected and is fixed together.
Advantage of the present invention:
Through shrinking connecting-rod of the present invention; Can realize reconciling automatically the extraction distance between handle position and the disconnected container; This moment is when pushing in the complete set of equipments by the order of link position-test position-open position or instead from complete set of equipments, pulling out in proper order when the propulsive mechanism unit; Can both guarantee that panel is in closure state, and can realize the divide-shut brake function of drawer switch cubicle control loop between link position, test position and open position.

Embodiment
Like Fig. 1,2, shown in 3, a kind of low-voltage distribution cabinet panel shrinking connecting-rod device comprises control piece and linkage component; Linkage component comprise one have inner chamber 11 outer bar 1, the interior bar 2 and that inserts outer bar 1 inner chamber 11 be arranged on the prepressing elastic 3 in outer bar 1 inner chamber 11; The bar wall of outer bar 1 is provided with an axial elongated slot 12; Control piece 4 is fixedly arranged on the interior bar 2 that stretches in the outer bar 1; When bar 2 was made telescopic displacement in the inner chamber 11 of bar 1 outside in making, control piece 4 can be fastened on the elongated slot 12 of said outer bar 1.
Control piece 4 is pins, and the interior bar 2 that stretches in the outer bar 1 is provided with a blind hole, and the blind hole on the interior interior bar 2 of pin and the outer bar of stretch into 1 closely cooperates and is fixed together.
Control piece 4 is screw also, and the interior bar 2 that stretches in the outer bar 1 is provided with a screw, and the screw on the screw interior bar 2 interior with stretching into outer bar 1 is spirally connected and is fixed together.
The other end of outer bar 1 is connected with the handle portion of cabin body door face board, and the bindiny mechanism of the other end of interior bar 2 through a speciality links to each other with circuit breaker in the body of cabin, the external handle of rotatable cabin, and its drive shrinking connecting-rod makes control loop be in conducting or closure state.Owing to be provided with a prepressing elastic in the shrinking connecting-rod, when the pusher unit of low-voltage distribution cabinet is in connection, disconnection, test position, make panel closed all the time through the shrinking connecting-rod in the body of cabin, prevented the entering of extraneous dust, coal dust.
When the pusher unit of power distribution cabinet is in link position; Quiet plug-in unit of secondary and the moving plug-in unit of the secondary in the drawer backboard that once moving plug-in unit in the once quiet plug-in unit of power distribution cabinet cabinet panel and the drawer backboard is path, cabinet panel are path; Spring in the shrinking connecting-rod is in state as shown in Figure 1 at this moment; The stroke of spring is in non-compressed state, and major loop, control loop are path at this moment.
When the pusher unit of power distribution cabinet is in test position; Once moving plug-in unit disconnection in the once quiet plug-in unit of power distribution cabinet cabinet panel and the drawer backboard, the quiet plug-in unit of secondary of cabinet panel and the moving plug-in unit of the secondary in the drawer backboard are path; Spring in the shrinking connecting-rod is in state as shown in Figure 2 at this moment; The stroke of spring is between minimum and the longest amount, obstructed, the control loop connection of major loop this moment.
When the pusher unit of power distribution cabinet is in open position; Once moving plug-in unit in the once quiet plug-in unit of power distribution cabinet cabinet panel and the drawer backboard breaks off, the quiet plug-in unit of secondary and the secondary in the drawer backboard of cabinet panel move the plug-in unit disconnection; Spring in the shrinking connecting-rod is in state as shown in Figure 3 at this moment; The stroke of spring is in minimum state, and this moment, major loop, control loop were obstructed.
Through shrinking connecting-rod of the present invention; Can realize reconciling automatically the extraction distance between handle position and the disconnected container; This moment is when pushing in the complete set of equipments by the order of link position-test position-open position or instead from complete set of equipments, pulling out in proper order when the propulsive mechanism unit; Can both guarantee that panel is in closure state, and can realize the divide-shut brake function of drawer switch cubicle control loop between link position, test position and open position.
