Description

Distribution box

Technical field

The utility model relates to a kind of distribution box, especially can make door can remain on the distribution box of enable possition after opening.

Background technology

The distribution box of Xiao Shouing generally comprises cover plate in the market, and cover plate is provided with door, and door pivots with cover plate and is connected, and can be locked in certain opening angle in order to make door after unlatching, generally can keep certain frictional force between door and the cover plate.But the door and the frictional fit of cover plate of the distribution box of some this structure can't be stablized the locking that ensures door; door falls to closing under the effect of regular meeting at gravity voluntarily; perhaps the door of some distribution box cooperates too closely with cover plate, causes frictional force very big, and the operator requires great effort when closing very much.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of distribution box, and this distribution box can be with the door steady lock at certain opening angle, and closed power can be provided when door is closed voluntarily.

For this reason, the distribution box that the utility model provides comprises cover plate, cover plate is provided with door, door pivots with cover plate and is connected, the both sides, end of door are provided with rotating shaft, rotating shaft phase opposite house in rotational direction interfixes, rotating shaft is connected with the upper end of first connecting plate, the first connecting plate phase countershaft in rotational direction interfixes, the rear end of the lower end of first connecting plate and second connecting plate is rotationally connected, the rear end co-rotation of the front end of second connecting plate and connecting rod is connected on first pivot, the both sides of first pivot are fixed with dividing plate respectively on the cover plate, offer the chute that mates with first pivot on the dividing plate, and the two ends of first pivot enter in the chute respectively, the front portion of cover plate upper connecting rod is provided with fixing baffle plate on the cover board, offer telescopic hole on the baffle plate, the front end of connecting rod enters in the telescopic hole, is with the compression spring on the connecting rod, the front end of compression spring is against on the baffle plate, and the rear end of compression spring is against can be with on the synchronization-moving retention device of connecting rod.

Because the door of the distribution box that the utility model provides is when cover plate rotates, door must overcome the power that is applied in the rotating shaft, driving first connecting plate when rotating shaft is rotated rotates, owing to be rotatably connected to interior the moving of chute that the two ends of first pivot of second connecting plate are limited at its both sides dividing plate, first connecting plate promote again second connecting plate overcome the compression spring restoring force move forward, simultaneously also driving connecting rod moves forward, rotate when rotating shaft and to make connecting rod move to its extreme position promptly when first connecting plate and the second connecting plate linear state, the compression spring is compressed into the shortest equally, the compression spring reaches ultimate attainment to the restoring force of connecting rod, it is maximum restoring force, when rotating shaft is rotated further connecting rod is bounced back immediately again, when promptly first connecting plate and second connecting plate form angle, the compression spring restoring force weaken, this moment if with door close must apply external force make the door can overcome the compression spring a maximum restoring force, therefore at this moment door can be locked in certain opening angle, because the restoring force that spring provides is highly stable, therefore door also can be locked highly stablely after opening.When the operator need close, only need downward turnover door that its maximum restoring force that overcomes the compression spring is got final product, after overcoming maximum restoring force, because the effect of compression spring, door can continue upset and close under the double action of gravity and compression spring restoring force, make distribution box the door close convenient, and can effectively avoid the operator close the door not in place.
