A kind of mutual inductor terminal board door leaf sealing structure
Technical field
It the utility model is related to transformer equipment terminal board technical field of sealing technology, and in particular to a kind of mutual inductor terminal board door leaf
Sealing structure.
Background technology
Existing outdoor type mutual inductor terminal board mostly uses flat plate sealing structure, i.e. mutual inductor terminal board is flange face,
The fastening force of flange plate washer is applied to by bolt seals seal deformation, and part flat plate sealing structure is even limited without seal
Position groove.For this structure when installing tablet cover board, there are bolt to fasten asynchronous problem, i.e., since seal and seal groove exist
Dimensional discrepancy, the bolt first fastened can oppress seal and be subjected to displacement, and cause the seal of rear fastening bolt part to be pressed again
Irregular deformation occurs when urgent, forms gap.
The content of the invention
To solve the above-mentioned problems, the utility model provides a kind of mutual inductor terminal board door leaf sealing structure, specific skill
Art scheme is as follows:
A kind of mutual inductor terminal board door leaf sealing structure includes door leaf, dovetail groove, doorframe, sealant rubber ring, door leaf handle, door
Fan handle limited device;Doorframe groove is provided with the doorframe;On the dovetail groove is arranged on the inside of door leaf, the fluid sealant
Circle is arranged in dovetail groove, where the position where the dovetail groove being arranged on door leaf and the doorframe groove being arranged on doorframe
Location matches are sealed with realizing;The door leaf handle limited device is arranged on the outside of door leaf, and door leaf handle is installed on door leaf handle
On limiting device.
Further, the dovetail groove uses fillet design, it is ensured that sealant rubber ring will not damage in installation process.
Further, the size of the sealant rubber ring and the size of dovetail groove, the size of doorframe groove match, it is ensured that sealing
It will not be got loose after cushion rubber installation, when door leaf closes, sealant rubber ring can be between the doorframe groove on dovetail groove and doorframe
Homogeneous deformation in the cavity of formation.
The utility model provides a kind of mutual inductor terminal board door leaf sealing structure, fans handle by door leaf closing back door and closes
Under the action of the pressure that position produces, sealant rubber ring produces elastic deformation in dovetail groove, doorframe doorframe groove, forms continuous sealing
Face, reaches sealing effect.Door leaf sealing structure provided by the utility model avoids traditional mutual inductor terminal board plate seal knot
Structure causes the problem of seal irregular deformation because bolt mounting process is bad, while the dovetail groove that sets of the utility model can be with
Sealant rubber ring is prevented to be shifted in door leaf closing course, doorframe groove may insure that crack between a door and its frame is effectively sealed by sealant rubber ring,
Door leaf handle limited device may insure door leaf handle pressure energy continuous effective when closing position.Door leaf handle limited device is used to limit
The change in location of door leaf handle during door leaf closure processed, it is ensured that pressure energy continuous effective.Door leaf sealing provided by the utility model
Bolt fastening installation is not required in structure, saves the working time, integral sealing effect is also significantly better than traditional mutual inductor terminal board
Flat plate sealing structure.

Embodiment
In order to be better understood from the utility model, the utility model is made with specific embodiment below in conjunction with the accompanying drawings further
Explanation:
As shown in Figure 1, Figure 2 and Figure 3, a kind of mutual inductor terminal board door leaf sealing structure includes door leaf 1, dovetail groove 2, doorframe
4th, sealant rubber ring 3, door leaf handle 7, door leaf handle limited device 8;Doorframe 4 is installed on mutual inductor terminal board tank wall 6, doorframe 4
Terminal board inner space 10 is formed with terminal board tank wall 6, doorframe groove 5 is provided with doorframe 4;Dovetail groove 2 is arranged in door leaf 1
On side, sealant rubber ring 3 is arranged in dovetail groove 2, and the position where the dovetail groove 2 being arranged on door leaf 1 is with being arranged on doorframe 4
Doorframe groove 5 where position be mutually matched to form sealing surface 9, when door leaf folding direction 11 is closure state, fluid sealant
Circle 3 is extruded to realize sealing;Door leaf handle limited device 8 is arranged on the outside of door leaf 1, and door leaf handle 7 is installed on door leaf handle
On limiting device 8.
Dovetail groove 2 uses fillet design, it is ensured that sealant rubber ring 3 will not damage in installation process.The ruler of sealant rubber ring 3
The very little size with the size of dovetail groove 2, doorframe groove 5 matches, it is ensured that sealant rubber ring 3 will not be got loose after installing, door leaf 1
During closure, homogeneous deformation in the cavity that sealant rubber ring 3 can be formed between dovetail groove 2 and doorframe groove 5.
The utility model is not limited to above-described embodiment, and the foregoing is merely the preferable of the utility model
Case study on implementation, is not intended to limit the utility model, and that is made where within the spirit and principles of the present invention is any
Modifications, equivalent substitutions and improvements etc., should be included within the scope of protection of this utility model.
