Description
Technical field
The invention belongs to switch cabinet body parts technical fields, more specifically, are related to a kind of with decompression function
Switchgear.
Background technology
Switchgear needs to carry out pressure release.Therefore, switchgear possesses the important configuration that decompression function is.It is of the prior art to open
Cabinet is closed, is to be connected head cover with cabinet by screw, and when needing pressure release, gases at high pressure are acted on head cover, promote head cover
Depart from cabinet, complete pressure release.Existing this structure, on the one hand, if gases at high pressure can not effectively promote head cover and cabinet
Separation, then can not timely and effective carry out pressure release, there are risk, even if effectively after pressure release, head cover be present with deformation or damage, it is necessary to
It is replaced, cost is caused to increase.
The content of the invention
The technical problems to be solved by the invention are：In view of the deficiencies of the prior art, a kind of simple in structure, cost is provided
It is low, gases at high pressure are generated in switch cabinet body when needing pressure release, can convenient and efficient realization pressure release, and head cover will not be caused
Appearance is deformed and damaged, and can be ensured that head cover resets in time again after pressure release, is realized and is sealed with cabinet reliable contacts, so as to effectively carry
The switchgear with decompression function of high switchgear usage safety performance.
Solve the problems, such as techniques discussed above, the technical solution that the present invention takes is：
For the present invention for a kind of switchgear with decompression function, the switchgear with decompression function includes cabinet, on cabinet
There is head cover in portion, and four blocks of cabinet plates form frame shape cabinet, and each cabinet plate inner top side sets an attaching plate elements, each living
Dynamic pin activity is through an attaching plate elements, and each removable pin upper end is fixedly connected with head cover, and each removable pin lower end sets /V
Block is set with a helical spring on each removable pin, and each helical spring upper end acts against the connecting plate above the helical spring
On part, each helical spring lower end is acted against on the limited block for the removable pin for being set with the helical spring.
The attaching plate elements includes plate connecting portion and plate support portion, and plate connecting portion and plate support portion are arranged to
L-shaped structure is not acted in the pressure on head cover in the cabinet, and head cover is configured to be resisted against every piece of cabinet
The structure of plate upper end, head cover are configured to the structure being resisted against simultaneously on the plate support portion of each attaching plate elements.
It is not acted in the cabinet in the gas pressure on head cover, helical spring is arranged in elongation state
Structure, do not act in the gas pressure on head cover in cabinet, helical spring is configured to apply downward thrust
Structure on the limited block of removable pin lower end.
In inverted T-shape structure, removable pin and limited block are an integral structure for the removable pin and limited block.
The head cover lower surface sets the shrinkage pool equal with removable pin quantity, and each shrinkage pool bottom sets and penetrates head cover
Through hole, each removable pin upper end end face set a threaded hole, and each bolt that connects is configured to through a through hole and one
The threaded hole of a removable pin upper end end face is screwed the structure of connection.
It is acted in the cabinet in the gas pressure on head cover, which is configured to promote head cover to remote
Structure from the movement of cabinet plate direction, when head cover is to away from the movement of cabinet plate direction, head cover is configured to pulling activity
The structure synchronously moved up is sold, when head cover pulling removable pin synchronously moves up, the limited block of removable pin lower end is arranged to
Enough extrusion spiral springs are in the structure of compressive state, and head cover away from cabinet plate direction after moving, the in vivo high pressure gas of cabinet
Body is configured to the structure to external pressure release by the clearance portion between head cover and cabinet plate upper surface.
The in vivo gases at high pressure of the cabinet by the clearance portion between head cover and cabinet plate after external pressure release, spiral
Spring is configured to apply structure of the downward thrust on the limited block of removable pin lower end again, and helical spring applies again
When on the limited block of removable pin lower end, the thrust that helical spring applies is configured to pull removable pin synchronous downward thrust
It moves down, so as to which head cover be driven to be resisted against the structure of cabinet plate upper end endface position again.
Technical solution using the present invention can obtain following advantageous effect：
The switchgear with decompression function of the present invention when pressure release is not required in switchgear, under helical spring effect, drives
Removable pin moves down, and head cover is driven reliably to be resisted against on the cabinet plate of cabinet, realizes the reliable closing and sealing of head cover.
And when generation gases at high pressure need pressure release in cabinet, the pressure of gases at high pressure is acted on head cover, and cabinet is promoted to move up,
At this point, head cover movement can drive removable pin to move up, and the limited block of removable pin meeting extrusion spiral spring contraction, so as to head cover
It is separated with cabinet plate upper end, forms pressure release clearance portion, gases at high pressure pressure release can be carried out, after gases at high pressure pressure release,
When the pressure of gases at high pressure is small, helical spring extends again at this time, under helical spring effect, removable pin is driven to move down,
Removable pin, which moves down, drives head cover to move down, and until being resisted against cabinet plate upper end again, completes a decompression cycle.Above-mentioned knot
Structure, can either ensure reliable pressure release, and when pressure release will not damage head cover again, it is ensured that head cover may be reused, and effectively reduce cost.
And be not required pressure release when, head cover can seal again with cabinet plate reliable contacts, it is ensured that switchgear entirety performance from
It influences.The switchgear with decompression function of the present invention, simple in structure, at low cost, generating gases at high pressure in switch cabinet body need to
When wanting pressure release, it is capable of the convenient and efficient pressure release for realizing cabinet, and head cover will not be caused to occur deforming and damage, energy again after pressure release
Enough ensure that head cover resets in time, realize and sealed with cabinet reliable contacts, so as to effectively improve switchgear usage safety performance.
