Description
Technical field
The utility model relates to the interlock of the preceding Xiamen of a kind of high pressure cabinet.
Background technology
Development along with power industry, the user requires also more and more higher to cabinet five anti-electrical equipment, before down gate interlock be that the high pressure cabinet guarantees the five anti-important interlockings of a cover, the preceding gate interlock of adorning on the former cabinet down, there have to be chain unreliable, installation needs to adjust, and also to prepare special-purpose emergency release handle, when needing emergency release, as no dedicated handle, preceding Xiamen is difficult to release and opens, and exists certain potential safety hazard.
Summary of the invention
In order to address the above problem, the utility model provides the interlock of the preceding Xiamen of high pressure cabinet of a kind of simple and reasonable, convenient use and good reliability.
To achieve these goals, the utility model is mainly solved by the following technical programs: the interlock of the preceding Xiamen of a kind of high pressure cabinet, comprise cam jacking block, the interlocking screw of fixedlying connected and be fixed on locating support on the side plate with the earthed switch operating axis, described locating support is socketed with the interlocking push rod, be socketed with stage clip on the interlocking push rod, one end of stage clip is against on the locating support, and the other end is against on the alignment pin that is located on the interlocking push rod; Described interlocking push rod contacts with the cam jacking block, and the other end of interlocking push rod is connected with blocking lever, and the other end of blocking lever is provided with slot, and described blocking lever is provided with interlocking shaft; Described interlocking screw is provided with the preceding Xiamen of cabinet and corresponding with the position of described slot.
As preferably, above-mentioned interlocking screw is fixed on the preceding Xiamen of cabinet by nut.
Because the utility model adopts above-mentioned structure, earthed switch separately the time, cam jacking block on the earthed switch operating axis will be depressed the interlocking push rod downwards, the interlocking push rod drives chain doing and counterclockwise rotates around interlocking shaft, slot on the latch lever will catch on the interlocking screw that is contained on the preceding Xiamen, preceding Xiamen can't be opened, guaranteed five anti-functions; As the need emergency release, as long as twist the interlocking screw that is contained on the preceding Xiamen in the outside with spanner.The reliability of gate interlock under before so the utility model can guarantee effectively, the fail safe that has improved cabinet to a great extent makes that operation is easier, and has cancelled the emergency release hole of preceding Xiamen.

Embodiment
Below in conjunction with accompanying drawing 1-5, the embodiment of the technical solution of the utility model is described in further detail.
Embodiment: the interlock of the preceding Xiamen of a kind of high pressure cabinet comprises cam jacking block 2, the interlocking screw 1 of fixedlying connected with earthed switch operating axis 10 and is fixed on locating support 5 on the high pressure side cabinet.
Be socketed with interlocking push rod 3 on the locating support 5, be socketed with stage clip 4 on the interlocking push rod 3, an end of stage clip 4 is against on the locating support 5, and the other end is against on the alignment pin 8 that is located on the interlocking push rod 3.
Interlocking push rod 3 contacts with cam jacking block 2, and the other end of interlocking push rod 3 is connected with blocking lever 6.Interlocking push rod 3 and latch lever 6 are connected by bolt looseness, and nut adopts and loosens nut, and when preventing that interlock from moving, coping screw becomes flexible and falls down and influence chain reliability.The other end of blocking lever 6 is provided with slot 9, also is provided with interlocking shaft 7 on the blocking lever 6, and latch lever 6 can rotate freely around interlocking shaft 7.
Interlocking screw 1 is fixed on the preceding Xiamen 11 of cabinet and corresponding with the position of described slot 9 by nut 12.
When the earthed switch separating brake, the earthed switch operating axis is rotated counterclockwise 90 °, be fixed on cam jacking block 2 on the earthed switch operating axis 10 and will withstand on the upper end of interlocking push rod 3, pressing interlocking push rod 3 to move downward compression press spring 4, interlocking push rod 3 drives blocking lever 6 around interlocking shaft 7 rotation counterclockwise, slot 9 on the blocking lever 6 will catch on the interlocking screw 1 that is contained on the preceding Xiamen 11, and preceding Xiamen 11 can't be opened, and has guaranteed five anti-functions.When earthed switch closes a floodgate, earthed switch operating axis 10 turns clockwise 90 °, the cam jacking block 2 that is fixed on the earthed switch operating axis 10 just can not pushed down interlocking push rod 3, interlocking push rod 3 is under the effect of stage clip 4, move upward, interlocking push rod 3 drives blocking lever 6 around the rotation of interlocking shaft 7 clockwise directions, and the slot 9 on the blocking lever 6 will separate with the interlocking screw 1 on being contained in preceding Xiamen 11, at this moment just can open preceding Xiamen.As the need emergency release, as long as twist the interlocking screw 1 that is contained on the preceding Xiamen 11 in the outside with spanner.
The utility model catches on the interlocking screw 1 that is contained on the preceding Xiamen 11 by the slot on the blocking lever 69, guaranteed the reliability of interlocking, and need not adjust when installing, and is very convenient.
