Description
Technical field
The utility model relates to a kind of support and fastening devices, specifically a kind of support for people's air defense door leaf and fastening devices, belongs to civil air defense projects safeguard production mounting technique field.
Background technology
All large-scale air-defense door leaf can be used in the civil air defense constructions and installations such as subway, tunnel, and the large-scale air-defense door leaf that civil air defense constructions and installations such as current subway, tunnel etc. uses is due to the impact of environmental factor, make it to be in the scope of vibrations for a long time, add the deadweight of large-scale air-defense door leaf heavier, when service life is longer, the situations such as that is sagging, motion that are easy to that door leaf is produced, not only affect functional performance, and security performance are poor.
Utility model content
For the problems referred to above, the problem that the utility model quasi-solution is determined is to provide a kind of simple and reasonable, easy for installation and the support for people's air defense door leaf that reliability is high and fastening devices, situation about prevent because the time is long, causing people's air defense door leaf sagging from the reason such as great, service life is long occurs, and ensures functional performance and the security performance of people's air defense door leaf.
For achieving the above object, the utility model is by the following technical solutions: a kind of support for people's air defense door leaf and fastening devices, comprise pedestal, front limit block, rear limited block, fixed cover, jack and jack box, described front limit block, rear limited block and fixed cover are all fixed on pedestal, described front limit block and described rear limited block are close to the front and back bottom position of people's air defense door leaf respectively, described fixed cover is positioned at the front of described rear limited block, described jack box is fixed on people's air defense door leaf rear, and be positioned at directly over described fixed cover, described jack is fixed in described jack box, described fixed cover is hollow, described mandril of lifting jack extended position is corresponding with the hollow position of described fixed cover.
As preferably, described front limit block front is provided with locating piece, and described rear limited block front is provided with cushion rubber bumper.
The beneficial effects of the utility model: the utility model structure is simple, reliability is high, by the motion of rear limited block restriction people's air defense door leaf opening direction, by the motion of front limit block restriction people's air defense door leaf closing direction, operation jack make it push rod stretch into fixed cover hollow in, and withstand on pedestal, thus by people's air defense door leaf jack-up, prevent because the time is long, from great, the situation that the reasons such as service life is long cause people's air defense door leaf sagging occurs, ensure that functional performance and the security performance of people's air defense door leaf, and the setting of locating piece and cushion rubber bumper, further ensure functional performance and the security performance of people's air defense door leaf.
In sum, the utility model has simple and reasonable, easy for installation and that reliability is high feature, situation about prevent because the time is long, causing people's air defense door leaf sagging from the reason such as great, service life is long occurs, and ensure that functional performance and the security performance of people's air defense door leaf.
