Abstract
The utility model provides a seal structure for translation formula people's air defense door, include the rubber strip that aerifys that arranges a week along the door frame, aerify the rubber strip and only aerify the pressurization and fill the gap between the door body and the door frame when the door body is closed, otherwise aerify rubber strip and door body contactless. The utility model has simple design, the inflatable rubber strip is not inflated in the state that the airtight door is opened and is protected by the steel bars at the two sides, even if the door body does not rub the inflatable rubber strip when sliding in a pushing and pulling way, the door body can be closed quickly, and the inflatable rubber strip can be ensured not to be damaged; after the air inflation, the air inflation rubber strip fills the gap between the door body and the door frame, so that a good sealing effect is achieved, and the shock wave resistance of the civil air defense door is enhanced.
Description
Technical Field
The utility model relates to a people's air defense equipment field, concretely relates to a seal structure for translation formula people's air defense door.
Background
The civil air defense door is a door of an entrance and an exit of civil protection engineering and is widely applied to civil air defense buildings. At present, a protective airtight door between protective units used in civil air defense engineering generally uses a solid rubber strip, the solid rubber strip is easy to damage at ordinary times due to the impact of a door body, the air tightness effect is influenced, air leakage is possible after the door body is subjected to impact waves, the airtight rubber strip is deficient on the aspect of preventing the impact waves,
SUMMERY OF THE UTILITY MODEL
The utility model provides a seal structure for translation formula people's air defense door to solve the not good problem of solid adhesive tape gas tightness.
The utility model provides a seal structure for translation formula people's air defense door, include the rubber strip that aerifys that arranges a week along the door frame, aerify the rubber strip and only aerify the pressurization and fill the gap between the door body and the door frame when the door body is closed, otherwise aerify rubber strip and door body contactless.
Preferably, the inflatable rubber strip is provided with the protective steel strip twice.
Preferably, the internal pressure of the inflatable rubber strip after the inflation is finished is 2.5kg/cm3～3kg/cm3。
The utility model has the advantages that:
the utility model has simple design, the inflatable rubber strip is not inflated in the state that the airtight door is opened and is protected by the steel bars at the two sides, even if the door body does not rub the inflatable rubber strip when sliding in a pushing and pulling way, the door body can be closed quickly, and the inflatable rubber strip can be ensured not to be damaged; after the air inflation, the air inflation rubber strip fills the gap between the door body and the door frame, so that a good sealing effect is achieved, and the shock wave resistance of the civil air defense door is enhanced.
Drawings

1-inflation rubber strip, 2-door body and 3-steel strip.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in detail with reference to specific embodiments.
Examples
The utility model provides a seal structure for translation formula people's air defense door, include and arrange the inflation adhesive tape 1 of a week along the door frame, it only aerifys pressurization and fills the gap between the door body and the door frame when the door body is closed to aerify adhesive tape 1, otherwise it is contactless with the door body 2 to aerify adhesive tape 1.
Further setting, it is equipped with protective billet 3 to aerify the adhesive tape both sides. A week is arranged on the door frame along aerifing adhesive tape 1 to billet 3, the high design of billet only need be higher than not aerify adhesive tape height can, and will with the door contactless. When aerifing the adhesive tape and not aerifing, aerify the adhesive tape and be in shrivelled state, its height is less than the height of protective billet, consequently at the in-process that removes the people's air defense door, the people's air defense door can not lead to the fact the striking or be the friction to aerifing the adhesive tape, has protected to a great extent and has aerifyd the adhesive tape.
Further setting, the internal pressure of the inflatable rubber strip after the inflation is finished is 2.5kg/cm3～3kg/cm3Higher than 1.5kg/cm for general use3The standard pressure value, fine having filled the gap that exists between door frame and the door body, strengthened the airtight effect of the door body and the steadiness of the door body, meanwhile, aerify the adhesive tape and be external to have pressure display to effectively monitor aerifing adhesive tape internal pressure and then make corresponding adjustment.
The above description is only an example of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
Claims (3)
1. The utility model provides a seal structure for translation formula people's air defense door, includes arranges the inflatable rubber strip of a week along the door frame, its characterized in that, inflatable rubber strip only aerifys the pressurization and fills the gap between the door body and the door frame when the door body is closed, otherwise inflatable rubber strip and the door body contactless.
2. The sealing structure for the translational type civil air defense door as claimed in claim 1, wherein protective steel bars are arranged at both sides of the inflating rubber strip.
