Below in conjunction with the accompanying drawings and specific embodiment is further described to the utility model.
As Figure 1-4, ring main unit grounding interlocking device, including limit pull rod 1, U-shaped card ring 2, base 3, lamina tecti 9,
Upper slide 15, lower skateboard 5, Zola's spring 14, right extension spring 6, fromer rail 13 and rear rail 8, base 3, lamina tecti 9, upper slide 15, under
The hole of the up and down motion of limit pull rod 1 is respectively provided with slide plate 5, fromer rail 13 and rear rail 8 are fixed on base 3, top cover
Plate 9 is fixed on fromer rail 13 and the top of rear rail 8, and fromer rail 13 and rear rail 8 are provided with left for upper slide 15 and lower skateboard 5
The outside of the track of right slip, upper slide 15 and lower skateboard 5 is respectively provided with fixed Zola's spring 14 and the grab of right extension spring 6
19, one end of Zola's spring 14 and right extension spring 6 is fixed on grab 19, and the other end is consolidated with Zola's spring fixed plate 18, right extension spring respectively
Fixed board 17 connects；Zola's spring fixed plate 18,17 U-shaped structure of right extension spring fixed plate, are fixedly installed in fromer rail 13 and rear rail 8
On；Zola's spring 14 is connected with Zola's spring fixed plate 18, upper slide 15 can be caused to have a restoring force to the right, similarly, will
Right extension spring 6 is connected with right extension spring fixed plate 17, and lower skateboard 5 can be caused to have a pulling force to the right.
Upper slide 15 is provided with the small hole in the big one end in one end, and lower skateboard 5 is provided with the small hole in the big one end in one end, limit pull rod
1 is provided with the upper groove 100 coordinated with the small bore end of upper slide 15, the low groove 101 with the small bore end cooperation of lower skateboard 5, bottom
End is provided with the neck 102 for being used for being connected with cabinet door, and top is taper end.
The top of limit pull rod 1 is through lamina tecti 9 and is arranged stage clip 10, jump ring 12 and plain washer 11, jump ring 12 and plain washer
11 are fixed on the top of limit pull rod 1, and stage clip 10 is compressed on lamina tecti 9；The reset condition of stage clip 10 is in compressive state, passes through
The reaction force of stage clip 10 realizes the up and down motion of limit pull rod 1, and lamina tecti 9 plays spacing effect.
In whole Machine Movement Process, cross and move to limit upper slide 15 and lower skateboard 5, fromer rail 13 and rear rail
8 are respectively arranged on the left side and the right side spacing only plate 7, and the spacing only both ends of plate 7 are fixedly installed on fromer rail 13 and rear rail 8, can be with
One spacing effect is played to upper slide 15 and lower skateboard 5.
Lock support 16 is led in the left side of base 3 provided with a left side, and lock support 4 is led in right side provided with the right side, for through and fixation core.
As viewed in figures 5-8, interlock of the present utility model is installed on the horizontal baffle 21 that the top of cabinet door 20 is connected,
It is connected by core 22 with the stroke expansion link on switch operating mechanism 24, core 22 is in conduit 23；U-shaped card ring 2 one
End insertion limit pull rod 1, one end are installed on the horizontal baffle 21 of cabinet door 20, and base 3 is fixed on horizontal baffle 21, are played solid
It is set for using；Cabinet door 20 is provided with the buckle 200 coordinated with the neck 102 of limit pull rod 1.
Core 22 respectively with the stroke expansion link and the upper slide 15 of interlock, lower skateboard 5 on switch operating mechanism 24
It is fixedly connected, the catch for being grounded mouth is in the lower end of ground connection gathering hole under switch closing and switch opening state；On switch operating mechanism 24
Catch present position when should be centre position, splice grafting can be operated and separating brake, that is, ground state will be beaten
When a reset condition.
Again as shown in Fig. 2 being influenceed slide plate 15 by the pulling force of Zola's spring 14 has an active force to the right, lower slide plate 5 exists
There is an active force to the left in the presence of right extension spring 6,1 one spacing effects of limit pull rod can be given, by the recessed of limit pull rod 1
Groove is fixed on the small intraoral of upper slide 15 and lower skateboard 5 so that limit pull rod 1 can not move.
When switch, which is got to, closes ground state, catch can block the gathering hole of combined floodgate separating brake, drive core 22 toward left movement,
Due to the reaction force of right extension spring 6, lower skateboard 5 by an active force to the right, turned right slip by lower skateboard 5, and limit pull rod 1 is slided
In the macropore for entering lower skateboard 5, lower skateboard 5 disappears for the position-limiting action of limit pull rod 1.Because the reset condition of stage clip 10 is in pressure
Contracting state, influenceed by the expansion force of stage clip 10, may be such that limit pull rod 1 up moves in the presence of stage clip 10, cabinet door 20 can
Remove；After cabinet door 20 are removed, the pulling force of limit pull rod 1 down disappears, and is only influenceed by the expansion force of stage clip 10, forces spacing drawing
Bar 1 continues up to move, while can promote upper slide 15 toward left movement, by the plastics core 22 of connection, the gear being grounded at mouth
Sector-meeting is up moved, and ground connection operation and the operation of on/off switch in this case will be unable to complete, and reach the purpose of interlocking.
Similarly, when cabinet door 20 is hung up, limit pull rod 1 is down moved, and upper slide 15 is turned right motion, is grounded at gathering hole
The past drop-down of catch, you can carry out ground connection sub-switching operation, mechanism catch can be in centre position again, and lower skateboard 5 is again to spacing drawing
Bar 1 has spacing, so moves repeatedly, just completes the function of preventing knife with ground (or ground wire) power transmission.
Mechanical movement more than, reach the purpose of ground connection interlocking, ensure in the state of cabinet door is opened, mechanism can not
Other operations are being carried out, and then are ensureing the safety of operator, the peril for avoiding maloperation from bringing.
In summary, the utility model is compact-sized, prevents knife power transmission with ground, be safe and reliable, be versatile, more
Generally it is applicable in the case of kind, does not have any restrictions requirement to the structure of cabinet door.
Certainly, it is to limitation of the present utility model that described above, which is not, and the utility model is also not limited to the example above, this
The those of ordinary skill of technical field, in essential scope of the present utility model, the variations, modifications, additions or substitutions made, all
The scope of protection of the utility model should be belonged to.
