Specific embodiment
The technical solution in the utility model is further illustrated with reference to the accompanying drawings and embodiments.
Interlocking mechanism's state for earthing when unearthed as depicted in figs. 1 and 2, cabinet body, Xia Menmen including high-voltage board
The co-axially fixed cam 3 of body 1, the operating shaft 2 of earthing, earthing；Interlocking mechanism includes be set to the inside of Xiamen door body 1 the
One lock construction 4, the second lock construction 5 and emergency release component 6 for being set to high-voltage board cabinet body；Wherein the first lock construction 4 includes such as
Hyoplastron 41 shown in fig. 6, the hyoplastron 41 are fixed at 1 inside of Xiamen door body by bolt and nut；Second lock construction 5 includes master
Axis 51, accessory 52 and the component 53 that automatically resets, the different-diameter section and hyoplastron 41 for passing through main shaft 51 due to the utility model
Cooperation realize the locking and unlocking of interlocking mechanism, main shaft 51 is made by way of the welding of two pin pin shafts here,
Centre forms the necking segment 511 that one section of diameter reduces, while hyoplastron 41 opens up the hyoplastron hole being axially moveable for main shaft 51
411, aperture is not less than the diameter of main shaft 51, and the edge in the hyoplastron hole 411 forms hyoplastron notch 412, the hyoplastron notch 412
Width is less than the diameter of main shaft 51 but is greater than the diameter of necking segment 511；Wherein, accessory 52 includes drive rod 521 and fixes
Bracket 522 on the cabinet, drive rod 521 are connected with 51 one end of main shaft and abut each other with cam 3, and main shaft 51 is inclined in order to prevent
It moves, bracket 522 and the axially vertical side of main shaft 51 offer pilot hole, and 51 other end of main shaft passes through pilot hole；Wherein, automatically
Reset assembly 53 includes reseting pressuring spring 531, pressure spring retaining ring 532 and pressure spring position limiting structure, and pressure spring position limiting structure is bracket 522 here
On groove, pressure spring retaining ring 532 is fixed at the periphery of main shaft 51, and reseting pressuring spring 531 is set in 51 periphery of main shaft and is located at pressure
Between spring position limiting structure and pressure spring retaining ring 532, when earthing is opened a sluice gate, the elastic force of reseting pressuring spring 531 makes drive rod 521 tight always
It is close to abut against 3 lower surface of cam；In this way, when needing to overhaul opening high-voltage board Xiamen, earthing ground connection, at this time such as Fig. 3 and Fig. 4
Shown, cam 3 rotates, and when the long axis direction of cam 3 turns to drive rod 521, cam 3 squeezes drive rod 521, drives main shaft 51
It is axially downward in the hyoplastron hole 411 of hyoplastron 41, when the hyoplastron notch 412 that main shaft 51 is moved to hyoplastron 41 is directed at necking down
When section 511, hyoplastron 41 can leave main shaft 51 to unlock, and reseting pressuring spring 531 is in compressive state；And when maintenance completion, make first
The hyoplastron notch 412 of hyoplastron 41 is directed at necking segment 511, and necking segment 511 is promoted in the hyoplastron hole 411 of hyoplastron 41 makes Xiamen door body
1 is in closed state, then dials from earthing, and the long axis of cam 3 leaves drive rod 521, and drive rod 521 loses the extruding of cam 3
Power, reseting pressuring spring 531 restore, and push main shaft 51 to move axially upward, necking segment 511 is made to leave the hyoplastron notch of hyoplastron 41
412, hyoplastron 41 is blocked and can not be left main shaft 51 and form locking by main shaft 51.
In order to preferably protect the component 53 that automatically resets, used here as the closing shape steel bracket using integral type.It is firm can
It leans on, is hardly damaged, the accidental damage of reseting pressuring spring 531 and main shaft 51 can be protected.
Impact force in order to prevent at closing time is excessive, leads to 41 excess impact main shaft 51 of hyoplastron and the main shaft 51 that fractures, here
It is also provided with hyoplastron position limiting structure 7, the cushions such as cushion are set on hyoplastron position limiting structure 7.
As Figure 1-Figure 8, in order to need emergency release in certain special circumstances, as earthing can not be grounded and be needed
Open the door maintenance when, here be provided with emergency release component 6, including handle 61, the handle socket being set in Xiamen door body 1 62,
It is set to the handle position limiting structure 63 of 51 end of main shaft and the rotatable handle supporting element 64 being set on cabinet body, 61 end of handle
End is detachably connected with handle position limiting structure 63, and the handle 61 forces drive main shaft 51 to be axially moveable by lever principle to be made
Necking segment 511 is aligned with the hyoplastron notch 412 of hyoplastron 41.
More firm in order to connect handle 61 with handle position limiting structure 63, when operation, is not easy to skid, handle position limiting structure
63 are attached in such a way that bumps are combined with 61 end of handle.Here handle position limiting structure 63 is set there are two through-hole, is used
Pin is fixed on 51 end of main shaft, and length of pin is less than through-hole length, and 61 end of handle is equipped with a protrusion, with handle position limiting structure
63 hole size matches, and when emergency release, the protrusion insertion through-hole of 61 end of handle is reliably connected.
It is bad to have an effect due to there is no hard point if directly depressing main shaft 51 with handle 61, therefore here on cabinet body side wall
Provided with rotatable handle supporting element 64, fulcrum of the rotatable handle supporting element 64 as lever can be when emergency release be operated more
Add laborsaving, straight pin of the rotatable handle supporting element 64 using nail in cabinet body side；
Since handle socket 62 is smaller, interior of the cabinet can not be seen clearly, tied in order to which handle 61 and handle limit is more easily accomplished
The quick connection of structure 63, is arranged location structure among handle 61, which is to be adapted with rotatable handle supporting element 64
Half bore.
Foreign object falls into high-voltage switch cabinet body and causes safety accident in order to prevent, is provided with also in door body such as Fig. 7 institute here
That shows is used to cover the socket cover board 65 of handle socket 62, and socket cover board 65 is arranged in Xiamen door body 1 by pin, can be around pin
360 rotation of nail.For safety, socket cover board 65 is provided with cover board notch 651, is provided in door body corresponding with cover board notch 651
And the pin for locking socket cover board 65.
Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover in the scope of the claims of the utility model.
