Description
Technical field
The utility model relates to a kind of power distribution equipment, particularly a kind of Mid-set cupboard grounded chain mechanism.
Background technology
Mid-cabinet is a kind of power distribution equipment that is used to install various High-Voltage Electrical Appliances, its minute the upper, middle and lower three-decker, the upper strata is bus and control room, the intermediate layer is a breaker chamber, lower floor is the cable vault.Wherein the back Xiamen of lower floor cable vault and preceding Xiamen need be chain with the earthed switch in the lower floor, and earthed switch is provided with the stock with the interlock of ground connection interlocking gear, but this stock in the vertical direction moves down.Earthed switch moves down when closing a floodgate, and back Xiamen and preceding Xiamen must be in the lock state, and damages power consumption equipment in the cabinet with anti-misoperation.When earthed switch was opened a sluice gate, preceding Xiamen just can be opened.Existing Mid-set cupboard grounded chain mechanism is installed on the secondary drainage plate of lower floor's side, when the maintenance internal unit is installed in the mid-cabinet lower floor cable vault, the secondary drainage plate must be pulled down, correspondingly, the ground connection interlocking gear that is installed on the secondary drainage plate must be removed, the dismounting Mid-set cupboard grounded chain mechanism is not only wasted time and energy, and the power consumption equipment of running into easily in the lower floor cable vault in disassembly process causes damage.
The utility model content
The purpose of this utility model is to overcome the prior art defective, provides a kind of simple in structure, easy to use, the Mid-set cupboard grounded chain mechanism that need not to unload during dismounting secondary drainage plate.
In order to realize above purpose, the utility model is by the following technical solutions: a kind of Mid-set cupboard grounded chain mechanism, it is characterized in that: described Mid-set cupboard grounded chain mechanism includes operating axis, connecting rod and locking bar, operating axis flatly is located between the back Xiamen and preceding Xiamen of lower floor cable vault, described operating axis radially with the interlock of the stock of earthed switch, operating axis is provided with the cam of a coaxial rotation, the middle part of locking bar is provided with rotation axis, connecting rod is vertical with operating axis to be provided with, locking bar and operating axis be arranged in parallel, the two ends of connecting rod respectively with the interlock of an end of cam and locking bar, the other end of locking bar is provided with latch hook and and is fixed on the movable fastening of lateral pin on the preceding Xiamen.
The beneficial effects of the utility model are: the utility model each parts all need not to install with the secondary drainage plate on, so during dismounting secondary drainage plate, do not need the ground connection interlocking gear is pulled down.Earthed switch and operating axis radially link, and the end that connecting rod drives locking bar rotates, and the other end of locking bar is provided with latch hook and movable fastening of lateral pin that is fixed on the preceding Xiamen, and is simple in structure, easy to use.
Below in conjunction with accompanying drawing the utility model is described in further detail
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A direction view of Fig. 1;
Embodiment
As shown in Figure 1 and Figure 2, a kind of Mid-set cupboard grounded chain mechanism includes operating axis 2, connecting rod 4 and locking bar 5.Operating axis 2 flatly is located between Xiamen 8, back and the preceding Xiamen 7, and the stock of earthed switch 1 and operating axis 2 radially link, and when earthed switch 1 closed a floodgate, earthed switch 1 stock drove operating axis 2 and rotates.Operating axis 2 be provided with one with the cam 3 of operating axis 2 coaxial rotation, connecting rod 4 and operating axis 2 vertical settings, locking bar 5 and operating axis 2 be arranged in parallel.One end of connecting rod 4 and cam 3 interlocks, the end interlock of the other end and locking bar 5.The two ends of connecting rod 4 are articulated in an end of cam 3 and locking bar 5 respectively.The middle part of locking bar 5 is provided with a rotation axis, and locking bar 5 is hinged on the right front door of lower floor cable vault, and the other end of locking bar 5 is provided with a U-shaped latch hook 51, is fixed with lateral pin 6 on the preceding Xiamen 7, lateral pin 6 vertical locking bars 5.This lateral pin 6 is located at the top of latch hook 51, and locking bar 5 fastens with lateral pin 6 under the drive of connecting rod 4 versatilely.When earthed switch 1 closed a floodgate, earthed switch 1 drove operating axis 2 and rotates, and cam 3 drivening rods 4 move down, and locking bar 5 rotates with an end of connecting rod 4 interlocks, and correspondingly, the other end forwards the position that fastens with lateral pin 6 to, and at this moment, preceding Xiamen 7 is in the lock state, and can not open.When earthed switch 1 closed a floodgate, each parts moved in the other direction, and locking bar 5 is removed and cooperated with the fastening of lateral pin 6, and this moment, preceding Xiamen 7 can be opened.
Certainly, the utility model is not limited only to above-mentioned execution mode, and any improvement to the utility model unsubstantiality all should be within protection range of the present utility model.
