When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 and 2, in order to disclose a steel door with a built-in door closer of the present invention, the steel door includes a door frame 1 and a door leaf 2 rotatably connected to the door frame 1, a door closer is arranged between the door frame 1 and the door leaf 2 in the prior art, and the door closer is used for realizing the effect of automatically closing the door leaf 2; the door frame 1 is provided with a sliding groove 3 with an opening facing the door leaf 2, a limiting block 4 is elastically arranged in the sliding groove 3, when a worker needs to hide the door, the limiting block 4 is driven to move from the sliding groove 3 in the sliding groove 3, when one end of the limiting block 4 is positioned in the sliding groove 3 and the other end of the limiting block 4 is positioned outside the sliding groove 3, when the door leaf 2 rotates to the position of the limiting block 4, the closing effect between the door leaf 2 and the door frame 1 is limited by the limiting block 4, and the hidden effect of the door leaf 2 is achieved; stopper 4 outer wall fixedly connected with rubber layer, when stopper 4 and 2 butts of door leaf, deformation takes place for the rubber layer, reduces stopper 4's degree of wear.

For the convenience of drive stopper 4's motion, door frame 1 is provided with the drive hole 5 with 3 perpendicular settings of spout, drive hole 5 and 3 intercommunication settings of spout, drive hole 5 is located spout 3 and deviates from the position at both ends, it is provided with actuating lever 6 to slide in the drive hole 5, be provided with the locating part that restricts stopper 4 motion between actuating lever 6 and the stopper 4, the locating part sets up to and is located the spacing hole 8 on stopper 4, when needing to close between door leaf 2 and the door frame 1, drive stopper 4 is towards 3 internal motion of spout, when spacing hole 8 on stopper 4 moves to the position of drive hole 5, actuating lever 6 is pegged graft in spacing hole 8, at this moment, stopper 4 is located spout 3 completely, prevent stopper 4 from to the closed influence of door leaf 2.

First spring 9 of fixedly connected with between 3 tip of spout and the 4 tip of stopper, when stopper 4 towards 3 internal motion of spout, first spring 9 is compressed, when actuating lever 6 pegs graft in spacing downthehole 8, first spring 9 is in compression state, when actuating lever 6 and spacing downthehole 8 separation, under the elastic action of first spring 9 recovery original shape, stopper 4 is driven towards 3 external motion of spout, stopper 4 when moving outside 3 spouts, the realization is to the restriction of 2 closed motions of door leaf.

A handle 10 is fixedly connected to one end, far away from the driving hole 5, of the driving rod 6, the handle 10 is perpendicular to the driving rod 6, a second spring 7 is sleeved outside the driving rod 6, two ends of the second spring 7 are fixedly connected with the handle 10 and the door frame 1 respectively, and two ends of the second spring 7 are fixedly connected with the handle 10 and the door frame 1 respectively; apply one for handle 10 and make actuating lever 6 towards the effort of keeping away from 5 direction motions in drive hole, handle 10 drives actuating lever 6 towards keeping away from 5 direction motions in drive hole, and second spring 7 is stretched, when spacing hole 8 moves to 5 positions in drive hole, removes the effort to handle 10, and actuating lever 6 is pegged graft in spacing hole 8, and second spring 7 is in the original shape state this moment, ensures the restriction effect of actuating lever 6 to stopper 4.

The implementation principle of the embodiment is as follows: when needing door leaf 2 to hide by default, exert an effort that makes its orientation keep away from drive hole 5 motion for handle 10, second spring 7 is stretched, stopper 4 and actuating lever 6 separation, under the spring action of first spring 9, stopper 4 is outside by the drive motion to spout 3, and stopper 4 limits the closed effect of door leaf 2, and when door leaf 2 and stopper 4 butt, the rubber layer takes place to deform, reduces the degree of wear between stopper 4 and the door leaf 2.
