Description
Technical field
The utility model relates to a kind of controller switching equipment, specifically is a kind of THE SHUTTER MECHANISM OF HV SWITCHGEAR CABINET.
Background technology
Valve mechanism is the important component part of high-tension switch cabinet; After its effect is the handcart type breaker in pulling out switch cubicle; Valve by shutter mechanism of switch cabinet covers the fixed contact in the switch cubicle, can electric shock accidents not take place because of touching fixed contact when personnel are operated in switch cubicle.The kind of drive that the shutter mechanism of switch cabinet of prior art in realization, time valve is opened or close has connecting rod transmission, the transmission of chain connecting rod and gear connecting rod transmission etc.Its structure is more complicated all usually, and can only adopt the method for padlock protection to realize the interlocking of valve mechanism and handcart, can not realize both direct interlockings, thereby can't prevent more fully that the staff from missing bumps electrified body and the electric shock accidents that meets accident.
The utility model content
The purpose of the utility model is to the above technical problem that will solve, and provides a kind of simple in structure, can be effectively and the handcart valve mechanism of directly interlocking.
The technical scheme of the utility model is following:
A kind of valve mechanism with interlock comprises bearing, on this bearing, is provided with coaxial hinged upper plate and lower plate; Around the coaxial torsion spring that is provided with, this torsion spring one end is fixed in bearing between said upper plate and the lower plate, and the other end is fixed in upper plate; Said upper plate rear end is provided with a draw-in groove; Also be provided with a sideboard on the said bearing, this sideboard and said upper plate and said lower plate are perpendicular, and the one of which end is corresponding with said upper plate rear end draw-in groove; Said sideboard one side is connected with a pressing plate, is provided with extension spring between this pressing plate and the said bearing.
As a kind of execution mode, be provided with a fixed support between said sideboard and the said pressing plate, this fixed support is fixed on the said bearing and is provided with a through hole, and said sideboard is connected through the stud shaft that passes this through hole with said pressing plate.
As a kind of execution mode, said fixed support and said sideboard are hinged.
Compared with prior art, only when circuit breaker cart shook into the service position, pressing plate was depressed the utility model, and sideboard moves to the direction away from draw-in groove, and valve just can be opened and operate as normal; Circuit breaker cart is not when the service position; Pressing plate is not depressed; Sideboard moves until being blocked by corresponding draw-in groove position to the draw-in groove direction; Can not open valve with hand this moment, thereby realized that valve mechanism and handcart directly interlock, and can play preventing that effectively the staff from missing the protective effect of bumping electrified body.Valve mechanism can only adopt the interlocking method of padlock protection before the utility model can replace, during more perfect overhaul of the equipments to staff's defencive function.

Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is made further detailed description.
Shown in Fig. 1 to 3; The valve mechanism with interlock that the utility model provides comprises bearing 1, upper plate 2 and lower plate 3; Upper plate 2 and lower plate 3 are coaxial hinged and be located on the bearing 1, and around the coaxial torsion spring 4 that is provided with, these torsion spring 4 one ends are fixed in bearing 1 between said upper plate 2 and the lower plate 3; The other end is fixed in upper plate 2, and being provided with of this torsion spring 4 is beneficial to resetting of control upper plate 2.Said upper plate 2 rear ends are provided with a draw-in groove 5; Also be provided with a sideboard 6 on the said bearing 1; This sideboard 6 is perpendicular with said upper plate 2 and said lower plate 3; And the one of which end is corresponding with said upper plate 2 rear end draw-in grooves 5, and said sideboard 6 one sides are connected with a pressing plate 7, are provided with extension spring 8 between this pressing plate 7 and the said bearing 1.
In order to strengthen the fastness of structure; Preferably be provided with a fixed support 9 between said sideboard 6 and the said pressing plate 7; This fixed support 9 is fixed on the said bearing 1 and is provided with a through hole, has a stud shaft to pass this through hole, and said sideboard 6 couples together through this stud shaft with pressing plate 7.
Said fixed support 9 is preferably hinged with the connected mode of said sideboard 6.
When circuit breaker in running order; When being about to handcart and shaking into the service position, the panel of handcart can be pressed onto pressing plate 7, extension spring 8 elongations; Pressing plate 7 drives coupled sideboard 6 to moving away from the direction of upper plate 2 and lower plate 3 (be cabinet the place ahead to); At this moment, the draw-in groove 5 of upper plate 2 and lower plate 3 rear ends does not block sideboard 6, and valve can be opened and operate as normal.
Extremely shown in Figure 6 like Fig. 4; When circuit breaker is in off-position; The handcart panel no longer is pressed onto pressing plate 7, and extension spring 8 is shunk, and pressing plate 7 resets and drives coupled sideboard 6 and moves to the direction of upper plate 2 and lower plate 3 (be cabinet rear to); Just block with an end of sideboard 6 until the draw-in groove 5 of upper plate 2 and lower plate 3 rear ends, this moment, valve can not move.
Through with upper type, the valve mechanism that the utility model provides only when circuit breaker cart shook into the service position, just can open by valve; When circuit breaker cart during, can not open valve with hand, thereby play the protective effect that prevents that staff's mistake from bumping electrified body not in the service position.
The utility model is not limited to above-mentioned execution mode; If spirit and scope that the various changes or the modification of the utility model do not broken away from the utility model; If these are changed and modification belongs within the claim and equivalent technologies scope of the utility model, then the utility model also is intended to comprise these changes and modification.
