Further, the driving device includes hoist engine, and hoist engine is connect by chain with suspension hook, in open state The sprocket wheel bypassed for chain is rotatably connected on wall surface above door leaf.

Further, the chain includes main chain and divides chain, and on the reel of hoist engine, one end is supplied to main chain one ends wound Few two pieces points of chains are connected in parallel on main chain, and each divide chain end respectively install there are one suspension hook.

Further, the hanging ring is evenly distributed on door leaf top surface.

Further, the sprocket wheel is located at the surface in the middle part of door leaf under open state.

Further, mounting base is connected on the wall surface, mounting base includes central shaft, and positioned at central shaft both sides Side plate；Two side plate upper ends are connected with seat board jointly, and the threaded post of several embedment wall surfaces is connected on seat board；Central shaft both ends It is affixed with both side plate lower end respectively, and be rotatablely connected by bearing and sprocket wheel.

Further, the opening of the suspension hook is hinged with baffle, and baffle is influenced to be connected to from opening inner side by elastic component The end of suspension hook.

Compared with the existing technology, concrete closed door described in the utility model has the advantage that：

Concrete closed door described in the utility model offsets the gravity of door leaf by hoist engine, to prevent door leaf from becoming Shape, inclination.

In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally Connection；It can be mechanical connection, can also be electrical connection；Can be directly connected, can also indirectly connected through an intermediary, It can be the connection inside two elements.For the ordinary skill in the art, on being understood by concrete condition State the concrete meaning of term in the present invention.

The utility model will be described in detail below with reference to the accompanying drawings and embodiments.

A kind of concrete closed door, as shown in Figure 1, including door leaf 1 and boom hoisting 2.Boom hoisting 2 is located at opening state 1 top of door leaf of state.Boom hoisting 2 includes suspension hook 21 and hoist engine 22.Hoist engine 22 is used as driving device, driving suspension hook 21 perpendicular Go straight up to drop.

Hoist engine 22 fixes on the ground, and is connect with suspension hook 21 by chain 23.Chain 23 includes main chain 231 and divides chain 232, for 231 one ends wound of main chain on the reel 221 of hoist engine 22, one end is connected in parallel on main chain 231 at least two pieces points of chains 232 On, and 232 end of chain is each divided to be also equipped with a suspension hook 21.Mounting base 3 is connected on wall surface, mounting base 3 includes central shaft 31, and the side plate 32 positioned at 31 both sides of central shaft；Two 32 upper ends of side plate are connected with seat board 33 jointly, affixed on seat board 33 There is the threaded post 34 of several embedment wall surfaces；31 both ends of central shaft are affixed with 32 lower end of both side plate respectively, and pass through bearing and chain 4 rotation connection of wheel.Sprocket wheel 4 is located at the surface at 1 middle part of door leaf of open state, and main chain 231 around sprocket wheel 4 and makes a point chain 232 naturally droop.
