Novel jack fixing device for civil defense door
The invention discloses a novel jack fixing device for a civil defense door. The device comprises a base, a front limiting block, a rear limiting block, a fixing sleeve, a jack and a jack box. The front limiting block, the rear limiting block and the fixing sleeve are fixed to the base. The front limiting block and the rear limiting block are tightly attached to the front bottom and the rear bottom of a civil defense door leaf respectively. The fixing sleeve is located in front of the rear limiting block. The jack box is fixed behind the civil defense door leaf and located over the fixing sleeve. The jack is fixed into the jack box. The fixing sleeve is hollow. The stretching-out position of a jacking rod of the jack corresponds to the hollow position of the fixing sleeve. The novel jack fixing device has the beneficial effects of being simple and reasonable in structure, convenient to install and high in reliability, the phenomenon that the civil defense door leaf droops due to the fact that time is long, the dead weight is large and the service life period is long is avoided, and the using performance and the safety performance of the civil defense door leaf are ensured.
