As shown in fig. 1 to 4, one embodiment of the present utility model provides a room door stopper, which includes: a case 1 and a driving section;
the top wall of the box body 1 is level with the ground, a first opening 2 is formed in the top of one end of the box body 1, and a second opening 3 is formed in the top of the other end of the box body 1;
the driving part comprises a ratchet wheel 4 mechanism, a pushing cylinder 7 and a lever 8, the ratchet wheel 4 mechanism comprises a ratchet wheel 4, a swinging rod 5 and a driving pawl 6, the ratchet wheel 4 and the pushing cylinder 7 are coaxially and rotatably arranged at one end of the box body 1, one end of the swinging rod 5 is rotatably connected with a ratchet wheel 4 wheel shaft, the other end of the swinging rod extends out of the first opening 2, one end side of the swinging rod 5 is connected with one end side wall of the box body 1 through a first spring 9, one end of the driving pawl 6 is rotatably connected with the middle part of the swinging rod 5, the other end of the driving pawl 6 is meshed with gear teeth of the ratchet wheel 4, a first pushing surface 701 and a second pushing surface 702 are alternately arranged on the axial side surface of the pushing cylinder 7, the distance between the first pushing surface 701 and the axial surface of the ratchet wheel 4 is smaller than the distance between the second pushing surface 702 and the axial surface of the ratchet wheel 4, the middle part of the lever 8 is rotatably connected with a supporting point of the box body 1, one end side of the lever 8 is connected with the bottom wall of the box body 1 through a second spring 10, and the other end side of the lever 8 is used for enabling the lever 8 to be connected with the lower edge of the upper end of the lever 8 to move at the upper edge of the opening of the second cylinder 7.
The room door stopper works as follows:
the door body 14 is rotatably connected to the door frame through a hinge, the box body 1 is buried under the ground of the rear corner of the door body 14, and the top wall of the box body 1 is flush with the ground. When the door 14 is not fully opened, the relative positions of the pushing cylinder 7 and the lever 8 are adjusted to enable the first pushing surface 701 to be attached to one end of the lever 8 (one end of the lever 8 is acted by the upward elastic force of the second spring 10), at this time, one end of the lever 8 is located at a high point of the movement track, the other end of the lever 8 is located at a low point of the movement track, and the other end of the lever 8 is located below the second opening 3.
At this time, the door body 14 is pushed to the fully opened state, and then the hand is released. In this process, the door 14 sweeps over the second opening 3, touches the upper end of the swing rod 5, pushes the swing rod 5 to swing towards the corner, and the swing rod 5 drives the ratchet 4 and the pushing cylinder 7 to rotate a specific angle through the driving pawl 6 (after the hand is loosened, the swing rod 5 returns under the elastic action of the first spring 9), so that the second pushing surface 702 is attached to one end of the lever 8 (one end of the lever 8 is acted by the upward elastic force of the second spring 10), at this time, one end of the lever 8 is located at a low point of the movement track of the lever 8, and the other end of the lever 8 is located at a high point of the movement track of the lever 8, so that the other end of the lever 8 is located above the second opening 3. At this time, even if the wind blows the door 14 to the fully closed state, the other end of the lever 8 prevents the door 14 from rotating, and the door 14 is prevented from being closed in a non-human-controlled state.
When the person subjective wishes to close the door body 14, the person pushes the door body 14, touches the upper end of the swing rod 5, pushes the swing rod 5 to swing towards the corner, and the swing rod 5 drives the ratchet wheel 4 and the pushing cylinder 7 to rotate a specific angle again through the driving pawl 6 (when the person closes the door, the swing rod 5 returns under the elastic action of the first spring 9), so that the first pushing surface 701 is attached to one end of the lever 8 again, and the other end of the lever 8 is lower than the second opening 3 again, so that the door body 14 is free of obstruction in the closing process.
In the technical scheme of the utility model, compared with the traditional magnet type door stopper for the door-inhale room, the door body 14 can bear larger wind blowing driving force, and the door body 14 is prevented from being accidentally closed, so that the door body 14 is kept in an open state.

As shown in fig. 1 and 2, in the specific embodiment, the other end of the lever 8 is fixedly connected to a blocking block 11.
In this embodiment, specifically, the other end of the lever 8 is fixedly connected to the blocking block 11, and when the other end of the lever 8 is at the high point of the movement track, the blocking block 11 extends out of the second opening 3 and is perpendicular to the top wall of the case 1.
In a specific embodiment, the intersection point of the center normal line of the first pushing surface 701 and the center normal line of the second pushing surface 702 coincides with the central axis of the ratchet wheel 4.
In this embodiment, specifically, when viewed from the axial direction of the pushing cylinder 7, the plurality of first pushing surfaces 701 and the plurality of second pushing surfaces 702 enclose a polygon, and the circles of the circumscribed circles of the polygon are overlapped with the central axis of the ratchet wheel 4, so that no matter the first pushing surfaces 701 or the second pushing surfaces 702 are attached to the lever 8, the distance between the lever 8 and the central axis of the ratchet wheel 4 is the length of the central normal line, and thus the attachment relationship between the lever 8 and the pushing cylinder 7 is relatively stable.
As shown in fig. 1, 2 and 4, in the specific embodiment, the ratchet wheel further comprises a non-return pawl 12, and the non-return pawl 12 is meshed with the gear teeth of the ratchet wheel 4.
In this embodiment, specifically, when the first spring 9 drives the swing rod 5 to return, the driving pawl 6 reversely sweeps the ratchet wheel 4, the ratchet wheel 4 does not reversely rotate, and stability of the attaching relationship between the pushing cylinder 7 and the lever 8 is further ensured.
In a specific embodiment, the box body further comprises a sealing cover plate 13, an inspection opening is formed in the top wall of the box body 1 between the first opening 2 and the second opening 3, and the sealing cover plate 13 covers the inspection opening.
