Description
Technical field
The utility model belongs to a kind of Novel switch cabinet valve self-locking device.
Background technology
The valve structure of traditional switch cubicle can be stirred respectively with hand by operator to win in succession and drive short connecting rod and lower valve downwards; Stirring down wins in succession upwards drives long connecting rod and upper valve, makes the valve connecting with electrical equipment can be easily by manual unlocking.The control that this valve structure is not subject to main switch or auxiliary switch dolly whether to enter service position, all can be struck with the hand open by operator, thereby has the accident potential of personal misoperation, and security reliability is poor, provides safeguard to safe operation and maintenance.
Summary of the invention
The purpose of this utility model is to provide a kind of Novel switch cabinet valve self-locking device, only in the time that main switch or auxiliary switch dolly enter service position, valve just can be opened, have simple in structure, reduce the accident potential of personal misoperation, for safe operation and maintenance provide good guarantee, easy for installation, the advantage of the good and long service life of result of use.
For this reason, the utility model is mainly made up of cabinet, upper plate, upper plate jack-post, lower plate, lower plate jack-post and axis.On, the front axle of lower plate is located on one end and the fixing axis of cabinet, on, the front end of lower plate is provided with the dead bolt of protrusion, the cabinet of dead bolt front end is provided with fixed head, fixed head is provided with jam plate groove, jam plate is positioned at jam plate groove, the middle bight axis nail axle of L-shaped switchboard is located on the fixed head in jam plate groove outside, the front end of switchboard is established slip slotted eye, the top of plate axle nail is positioned at sliding tray hole, the lower end of plate axle nail is connected with the middle part, upper surface of jam plate, one end of spring is connected with fixed head, the other end of spring is connected with the front end of switchboard, the front end card top dead bolt of jam plate when locking valve, the jam plate that the rear end that accessory cart holds switchboard drives switchboard to be positioned at jam plate groove is mobile jam plate and dead bolt released state while forming folding valve backward.Described switchboard is L-shaped.Said structure design has realized the purpose of this utility model.
The utility model is only in the time that main switch or auxiliary switch dolly enter service position, and valve just can be opened, and has simple in structure, reduce the accident potential of personal misoperation, for safe operation and maintenance provide good guarantee, easy for installation, the advantage of the good and long service life of result of use.
Accompanying drawing explanation
Fig. 1 is (state when locking valve) of the present utility model structural representation.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Status architecture schematic diagram when Fig. 3 is folding valve of the present utility model.
Embodiment
As shown in Figure 1 to Figure 3, a kind of Novel switch cabinet valve self-locking device, is mainly made up of cabinet 10, upper plate 1, upper plate jack-post 3, lower plate 9, lower plate jack-post 6 and axis 8.On the rear end of winning in succession be connected with short connecting rod and lower valve respectively with upper plate jack-post.Under the rear end of winning in succession be connected with long connecting rod and upper valve respectively with lower plate jack-post.Like this, in the time of structure folding of the present utility model, making to win in succession to drive short connecting rod and lower valve downwards; Making down to win in succession upwards to drive long connecting rod and upper valve, and the valve that makes to connect with electrical equipment is controlled to be opened.
The front axle of upper and lower connecting plate is located on one end and the fixing axis 8 of cabinet.The front end of upper and lower connecting plate is provided with the dead bolt 7 of protrusion, and the front end of upper and lower connecting plate is respectively provided with the dead bolt of a protrusion.
The cabinet of dead bolt front end is provided with fixed head 5, and fixed head is provided with jam plate groove 12, and jam plate 4 is positioned at jam plate groove, and jam plate can slide in jam plate groove.
The middle bight axis of L-shaped switchboard 2 is followed closely on the fixed head that 13 axles are located at jam plate groove outside.The front end of switchboard is established slip slotted eye 14, and the top of plate axle nail 15 is positioned at sliding tray hole, and can in slip slotted eye, slide, and the lower end of plate axle nail is connected with the middle part, upper surface of jam plate.One end of spring 11 is connected with fixed head, and the other end of spring is connected with the front end of switchboard.
The front end card top dead bolt of jam plate when locking valve, the dead bolt card of upper plate when locking valve withstands on the lower surface of jam plate front end; The dead bolt card of lower plate withstands on the upper surface of jam plate front end; Thereby make upper and lower connecting plate fixing locked, can not move up and down.
The jam plate that switchboard is driven be positioned at jam plate groove when the rear end that accessory cart holds switchboard is mobile jam plate and dead bolt released state while forming folding valve backward.Described switchboard is L-shaped.
As shown in Figure 1 to Figure 2, when use, the front end card top dead bolt of jam plate when locking valve, the dead bolt card of upper plate when locking valve withstands on the lower surface of jam plate front end; The dead bolt card of lower plate withstands on the upper surface of jam plate front end; Thereby make upper and lower connecting plate fixing locked, can not move up and down.The valve connecting with electrical equipment can not be by manual unlocking.
As shown in Figure 3, when accessory cart (is not marked in figure, the rear end motion that only marks switchboard to, it is along the orbital motion in cabinet) rear end that holds switchboard is while driving switchboard to be positioned at the jam plate of jam plate groove to move backward, jam plate and dead bolt released state while forming folding valve.Be switchboard rear end by accessory cart hold to axis near time, following closely 13 under the effect of axle take axle, the front end of switchboard drives plate axle nail 15 that jam plate is moved backward in jam plate groove, makes the front end of jam plate and kayser tongue lose pintle hook lock, and making to win in succession to drive short connecting rod and lower valve downwards; Making down to win in succession upwards to drive long connecting rod and upper valve, and the valve that makes to connect with electrical equipment is controlled to be opened, and now spring is stretched.Otherwise when accessory cart resets, the rear end of switchboard loses bearing force, under spring reset effect, switchboard resets and drives jam plate to move forward in jam plate groove, and the front end of jam plate is engaged with dead bolt, forms locking states.Obviously, when main switch enters service position, jam plate and dead bolt released state while forming folding valve.
In a word, the utility model is only in the time that main switch or auxiliary switch dolly enter service position, and valve just can be opened, have simple in structurely, reduce the accident potential of personal misoperation, for safe operation and maintenance provide good guarantee, easy for installation, the advantage of the good and long service life of result of use.
