Description
Technical field
The utility model relates to power transmission and distribution technical field, particularly, relates to a kind of batch meter with chamber door Closed control mechanism.
Background technology
Batch meter switchgear, measuring instrument, protective device and auxiliary equipment to be assembled in by electrical wiring requirement to close or in semiclosed metal safe or on screen width, the low-voltage distribution equipment of formation, is usually used in each, joins, in electric substation.
Batch meter generally comprises casing and the chamber door of an opening, and chamber door is arranged on its open side, and side is rotatably connected on casing by hinge, opposite side is provided with door lock, and generally, chamber door is closed and locked by door lock, when needing to open chamber door, first open and open door lock, then pull open chamber door.
General batch meter is only equipped with box door lock for controlling the folding of chamber door, once door lock damages, chamber door is easily opened by wind, and batch meter is opened, even if the abatement of wind or stopping, batch meter chamber door is still in open mode, very dangerous.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of distribution box with chamber door Closed control mechanism, and its chamber door Closed control mechanism can ensure that distribution box is in normally off, ensures device security in distribution box.
The technical scheme in the invention for solving the above technical problem is:
There is the batch meter of chamber door Closed control mechanism, comprise casing and the chamber door being arranged on casing front, described chamber door is connected on a side plate of casing by Fixed hinge, two leaf of hinge one of Fixed hinge are fixed on chamber door side, another is fixed on side plate, the side that described chamber door is connected and fixed hinge is also provided with a flat board, and this platen parallel is arranged in chamber door, is connected with Limiting hinge between the side plate be connected and flat board with Fixed hinge; Described Limiting hinge comprises hinge axis, the first leaf of hinge and the second leaf of hinge, and described first leaf of hinge and the second leaf of hinge, in " recessed " font, are made up of a horizontal edge and two vertical edges; First leaf of hinge is fixed on the dull and stereotyped back side, and two vertical edge is rotatably connected on the two ends up and down of hinge axis respectively; Described second leaf of hinge is fixed on side plate, and two vertical edge is also rotatably connected on the two ends up and down of hinge axis respectively, and described hinge axis is also arranged with torsion spring, and torsion spring torque arm is fixed on the dull and stereotyped back side, and another torque arm is fixed on side plate.Aforementioned torsion spring is the torsion spring that the angle under the normality not having External Force Acting between two torque arm is greater than 90 degree, in this programme, torsion spring, Limiting hinge and the flat board automatic reset mechanism as chamber door is set, under the effect not having external force, the elastic force of torsion spring makes slab normal in side plate, thus chamber door is tightly covered on casing, even if chamber door door lock damages, be also not easy to be opened by wind; Temporarily blown open even if meet with high wind, the abatement of wind and after disappearing the elastic force of torsion spring chamber door is covered on casing again, make casing be in closed condition, can device security in effective guarantee batch meter.
As further improvement of the utility model, the case lid four sides of described casing stretches out, described dull and stereotyped upper end is provided with spacing hole, described case lid offers limiting through hole in its part extended towards side plate, limiting through hole equals the horizontal range of spacing hole to the dull and stereotyped back side to the horizontal range of side plate, and limiting through hole equals the horizontal range of spacing hole to chamber door to the horizontal range in the front of casing.Because the active force of torsion spring exists, the active force that external force overcomes torsion spring must be applied when opening chamber door, in the present embodiment, case lid and flat board arrange corresponding hole, when chamber door open, flat board is close to side plate and is, these two hole in the vertical directions are located along the same line, only need use gag lever post from the limiting through hole of case lid, be down inserted into dull and stereotyped spacing hole, flat board can be fixed, be that chamber door is in open mode, to exert a force fixed flat planar without staff's moment, save manpower.
Further, in order to make torsion spring two torque arm more stable with contact position that is dull and stereotyped and side plate, the described dull and stereotyped back side and side plate all offer the groove of the torque arm of accommodation torsion spring.
Further, in order to strengthen the stability that torsion spring and the first leaf of hinge are connected on hinge axis with the second leaf of hinge, prevent from skidding off from hinge axis two ends, described hinge axis is cylindric, its top and bottom are respectively arranged with columned guide vane end stop, and the radius of guide vane end stop is greater than the radius of hinge axis.
To sum up, the beneficial effects of the utility model are:
1, the utility model has set up the automatically reset automatic reset mechanism be made up of torsion spring, Limiting hinge and flat board making chamber door, under the effect not having external force, the elastic force of torsion spring makes slab normal in side plate, thus chamber door is tightly covered on casing, even if chamber door door lock damages, be also not easy to be opened by wind; Temporarily blown open even if meet with high wind, the abatement of wind and after disappearing the elastic force of torsion spring chamber door is covered on casing again, make casing be in closed condition, can device security in effective guarantee batch meter;
2, the utility model overcomes the position-limit mechanism of the active force of torsion spring after additionally providing and opening chamber door, makes artificially to exert a force to keep chamber door to be in open mode, saves manpower;
3, simple and compact for structure, easy to use and flexible of the present utility model, and each mechanism stable connection is reliable.
