Detailed Description
In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
As shown in fig. 1 to 4, in a preferred embodiment, the civil air defense door convenient to promote of the present invention mainly includes a door frame 1 and a door leaf 2, the door leaf 2 can adopt a reinforced concrete structure, one side of the door leaf 2 is hinged to the door frame 1, a rotatable auxiliary wheel 3 is arranged below the door leaf 2, and the auxiliary wheel 3 is used for supporting the door leaf 2 when the door leaf 2 is opened.
Specifically, the auxiliary wheel 3 includes a wheel seat 4, a roller 5, a link 6, and a spring 7. The upper end of the wheel seat 4 is hinged with the lower end of the inner side face of the door leaf 2, the connecting rod 6 is a conventional telescopic rod, one end of the connecting rod 6 is connected with the lower end face of the wheel seat 4, the other end of the connecting rod is connected with the axle center of the roller 5, and the spring 7 is sleeved on the periphery of the connecting rod 6. When the door leaf 2 is opened, the auxiliary wheel 3 can be rotated to the lower part of the door leaf 2, and the door leaf 2 is supported by the spring 7 and the roller 5, so that the deformation of the door leaf 2 due to self weight is effectively avoided.
The one side of wheel seat 4 towards door frame 1 is equipped with first direction inclined plane 8, and the one side of door frame 1 towards the inboard corresponds first direction inclined plane 8 and is equipped with lug 9, and this lug 9 protrusion is in the surface of door frame 1, has the second direction inclined plane 10 with first direction inclined plane 8 assorted on the lug 9. When closing door leaf 2, door leaf 2 rotates towards door frame 1, first direction inclined plane 8 offsets with second direction inclined plane 10 this moment, under the mutual extrusion of first direction inclined plane 8 and second direction inclined plane 10, spring 7 contracts, wheel seat 4 drives other parts of auxiliary wheel 3 and rotates towards door leaf 2 inboard simultaneously, make auxiliary wheel 3 pack up when closing the door automatically, can not influence the action and the speed of closing door leaf 2, and under the supporting role of auxiliary wheel 3, the thrust that needs when closing the door can be reduced greatly, make people's air defense door use more convenient and fast.
