Description
Technical Field
The utility model relates to a people's air defense door technical field especially relates to a people's air defense door locking structure.
Technical Field
The civil air defense is measures and actions which are taken by governments to mobilize and organize people for preventing enemy air attacks and eliminating consequences, and is called civil air defense for short. The air defense system is a soil air defense system formed by air defense and field operation air defense together, and is an important component of modern national defense.
The civil air defense project is an underground protective building which is independently built for guaranteeing shelter of war personnel and materials, command of civil air defense and medical aid, and a basement which is built by combining ground buildings and can be used for air defense in war.
People's air defense door is the door of people's protection engineering access & exit, and in order to ensure people's air defense door's protecting effect, people's air defense door's weight is very big usually, opens and close and all needs great dynamics, and in the same way, people's air defense door is opening and close the in-process, and the collision harm that inertia caused is big is also great, for this reason, has certain potential safety hazard.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an invention goal structure is locked to people's air defense door, adopts the utility model provides a technical scheme can prevent that people's air defense door from taking place to remove in the open mode, and then causes the collision.
In order to solve the technical problem, the utility model provides a civil air defense door locking structure, which comprises a screw rod, a screw rod sleeve sleeved outside the screw rod and a lock sleeve matched with the screw rod; the screw sleeve is fixed at the lower part of the civil air defense door leaf; the lock sleeve is pre-buried in the ground.
Preferably, the screw sleeve is fixed on the side surface of the civil air defense door facing the civil air defense wall in the opening state.
Preferably, the lock sleeve comprises a bottom plate and a sleeve piece which are fixed by welding; the sleeve is provided with a sleeve hole opposite to the screw.
Preferably, a steel bar hook is formed on the bottom surface of the bottom plate; the steel bar hook is hooked with the pouring steel bar in the ground.
Preferably, the bottom plate and the partial sleeve are cast in the ground.
From the above, use the utility model provides a technical scheme can obtain following beneficial effect: through screw rod and lock sleeve cooperation, can lock the people's air defense door in lock sleeve department, and then avoid the people's air defense door to take place to remove, reduce the collision risk.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments of the present invention or the prior art will be briefly described below. It is obvious that the drawings in the following description are only some embodiments of the invention, and that for a person skilled in the art, other drawings can be derived from them without inventive faculty.
Fig. 1 is the utility model discloses civil air defense lock locking structure schematic diagram.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The weight of people's air defense door is usually very big, opens and close and all needs great dynamics, and in the same way, people's air defense door is opening and close the in-process, and the collision harm that inertia caused is big is also great, has certain potential safety hazard for this reason.
As shown in fig. 1, in order to solve the above technical problem, the present embodiment provides a locking structure of a civil air defense door, which includes a screw 20, a screw sleeve 30 sleeved outside the screw 20, and a lock sleeve 40 engaged with the screw 20.
Wherein the screw sleeve 30 is fixed at the lower part of the civil air defense door leaf; the lock sleeve 40 is embedded in the ground.
In order to prevent collision with the air defense door 10, the screw housing 30 is fixed to the side of the air defense door 10 facing the air defense wall in the opened state.
Since the weight of the civil air defense door 10 is large and a stable locking structure is required, for this reason, the lock sleeve 40 provided in the present embodiment includes a bottom plate 41 and a sleeve member 42 fixed by welding, wherein the sleeve member 42 is formed with a sleeve hole facing the screw rod 20.
Specifically, a reinforcement hook 43 is formed on the bottom surface of the bottom plate 41, and the reinforcement hook 43 is hooked with a casting reinforcement in the ground. The bottom plate 41 and the partial sleeve 42 are cast in the ground. The above structure ensures the stability of the lock case 40.
When the people's air defense door was in the state of opening, on manual rotatory to the lock sleeve with the screw rod, through screw rod and lock sleeve cooperation, can lock people's air defense door in lock sleeve department, and then avoid people's air defense door to take place to remove, reduce the collision risk.
The above-described embodiments do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the above-described embodiments should be included in the protection scope of the technical solution.
