Specific embodiment
It should be noted that in the absence of conflict, the feature in the embodiments of the present invention and embodiment can
To be combined with each other.
For make technological means of the utility model and reach purpose intention it can be readily appreciated that it is special combine be specifically illustrating into
One step illustrates.
This example discloses a kind of city underground rigid suspension OCS sealing device, including door leaf 1, door leaf hole 2, semicircle
Cover board 3, tight fixed bolt 4 and seal rubber block 5.
As shown in Figure 1 to Figure 3, the door leaf 1 uses I-steel welding fabrication truss structure, then passes through plug welding form
Inside and outside panel is welded on door leaf 1 welding fabrication, one overall structure on truss structure, setting is mutually 60 on every side door fan 1
The threaded hole of degree (angle between adjacent screw holes and door leaf hole circle center line connecting) is for installing tight fixed bolt 4 for semicircle cover board
3 are fixed on door leaf 1, and the compression of seal rubber block 5 is used for the gap between seal cover board 3 and contact net；The door leaf hole 2 exists
The semi-circular hole that about 1.5-2 times of a contact net radius is opened on every side door fan 1, for installing seal rubber block 5 and semicircle lid
Plate 3 is sealed rigid suspension OCS and passes through it；The semicircle cover board 3 is designed using 34 formula structure of boss,
The interior outside of door leaf 1 is respectively arranged one, and the compression for being sealed rubber block 5 seals, semicircle 3 boss of cover board, 34 internal diameter 31
Greater than rigid suspension OCS 3-5mm of diameter, minor eccentricities and small sagging, semicircle cover board 3 suitable for rigid suspension OCS
34 outer diameter 32 of boss it is identical as the diameter in door leaf hole 2 semicircle cover board 3 is cooperated with door leaf hole 2, outside semicircle cover board 3
Side setting is mutually 60 degree (angle between adjacent mounting hole and cover board circle center line connecting) 3 mounting holes 33, by tight fixed bolt 4 with
Threaded hole cooperation on door leaf 1 is fixed on door leaf, is compressed to seal rubber block 5；The tight fixed bolt 4 is set altogether
The medial and lateral for setting 12 every side door fans 1 are 3, by cooperating with the threaded hole being arranged on door leaf 1 for carrying out semicircle
The fastening of shape cover board 3, to realize the compression sealing of seal rubber block 5 indirectly.
As shown in figure 4, the seal rubber block 5 uses semi-circular design and ethylene propylene diene monomer (EPDM) material, have good
Good sealing performance, the internal diameter of seal rubber block 5 is compared with about 2-4mm of rigid suspension OCS diameter, since rubber sealing block 5 has
Certain compressibility, so that rigid suspension OCS is wrapped in the inside by two pieces of seal rubber blocks 5 makes its better tightness, outside
Diameter is identical as door leaf hole 2 to be installed in inside door leaf hole 2, and the length of rubber sealing block 5 is greater than the semicircle in outside in door leaf 1
About 3-5mm of spacing between the boss 34 of cover board 3, in sealing since semicircle cover board 3 is by tight fixed bolt 4 and setting
Cooperate on door leaf 1 and semicircle cover board 5 is fixed on door leaf 1, is designed by the boss 34 of semicircle cover board 5 by rubber seal
Block 5 compresses, and then to the good sealing of flexible contact web form.
As shown in figure 5, seal rubber block 5 is equipped with hemispherical projections 51, sealing effect is further increased.
Working principle: when converting from wartime to peacetime production and vice versa occurs, natural person closes door leaf 1, since door leaf hole 2 is arranged on every side door fan 1,
The door leaf bore dia of formation is greater than the diameter of rigid suspension OCS, and after door leaf 1 is closed, natural person is by certain measure (such as with wooden
Stick is disclosed into) two pieces of rubber sealing blocks 5 are inserted respectively into corresponding door leaf hole 2, the then boss 34 in semicircle cover board 3
It is inserted partially into door leaf hole 2, then tight fixed bolt 4 is passed through into the mounting hole on semicircle cover board 3 and is arranged on door leaf 1
Semicircle cover board 3 is fixed on door leaf 1 by threaded hole cooperation, since seal rubber block 5 has certain compressibility, passes through half
The fastening of circular cover 3 is so that seal rubber block 5 is pressed in door leaf hole 2, since the internal diameter of seal rubber block 5 is greater than flexibility
The diameter of contact net, so there is certain interval between contact net and seal rubber block 5, but the length of rubber sealing block 5 is big
In the about 3-5mm of spacing in door leaf 1 between the boss 34 of the semicircle cover board 3 in outside, pass through the boss 34 of semicircle cover board 5
The portion compresses that rubber sealing block 5 is grown are radially deformed, after the closing of door leaf 1 seal rubber block 5 are compacted and wrap
Rigid suspension OCS, to realize the sealing of rigid suspension OCS.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
