[0035] The door stop structure 2 comprises: a door stop body 21, the door stop body 21 is in the shape of a rectangle and an arc, the chord length of the arc is greater than the side of the rectangle, and two first staggered steps 211 are formed at the junction of the two;

[0036] The door stop body 21 is provided with a third hole 212 matched with the first hole 141, the door stop structure rotating shaft 22 passes through the first hole 141 and the third hole 212 to hinge the door stop body 21 in the outer shell 1, and the door stop body 21 can rotate around the door stop structure rotating shaft 22. The door stop structure rotating shaft 22 is fixed outside the second side plate 14 by using the door stop structure snap spring 23 at both ends;

[0037] The limiting structure 3 comprises: a limiting body 31, the limiting body 31 is provided with a fourth hole 311 matched with the second hole 142, the limiting structure rotating shaft 32 passes through the second hole 142 and the fourth hole 311 to hinge the limiting body 31 in the outer shell 1, and the limiting body 31 can rotate around the limiting structure rotating shaft 32, and the limiting structure rotating shaft 32 is fixed outside the second side plate 14 by using the limiting structure snap spring 33 at both ends.

[0038] The side of the limiting body 31 adjacent to the door stop body 21 is provided with a second misalignment step 312 matched with the first misalignment step 211, and the two are clamped for preventing the door stop body 1 from rotating and preventing it from exposing the ground. The side of the door stop body 21 not clamped with the second misalignment step 312 is limited by the part of the first side plate 13 protruding from the top plate 1, preventing the door stop body 21 from rotating and exposing the ground from this side. The side of the limiting body 31 away from the door stop body 21 is provided with a spring hole 313, which is preferably a rectangular hole, but can also be a circular hole or a hexagonal hole. A spring 34 is installed in the spring hole 313, and the two ends of the spring 34 abut against the spring hole 313 and the first side plate 13 respectively, exerting a spring force on the limiting body 31 to make the first misalignment step 211 and the second misalignment step 312 clamped tightly.

[0039] The side of the limiting body 31 away from the door stop body 21 is also provided with a notch 314 to increase the maximum stroke when the limiting body 31 is pushed away from the door stop body 21, ensuring that after the limiting body 31 is pushed, the door stop body 21 is not limited and can rotate smoothly to expose the ground.

[0040] The top of the limiting body 31 is provided with a pushing card slot 315, which can be inserted with a screwdriver or other tools to push the limiting body. The pushing card slot 315 can also not be provided, and the top of the limiting body 31 can be provided with anti-slip patterns (not shown in the figure) for easy manual pushing of the limiting body.

[0041] There is a first bottom plate bolt hole 121 at each end of the first bottom plate 12, which can be connected to the building body with bolts such as expansion bolts 122 to increase the connection strength.

[0042] Number of installations: (1) When limiting by magnetic attraction principle, only one set of hidden door leaf rotation limiter 4 is needed for a single door leaf, but the corresponding suction block (not shown in the figure) needs to be installed on the door leaf. The suction block can be designed conventionally, and one of the door stop body 21 and the other is made of permanent magnet; (2) When limiting by non-magnetic attraction principle, two sets of hidden door leaf rotation limiters 4 are needed for a single door leaf to limit it front and back, that is, the distance between the two hidden door leaf rotation limiters 4 is slightly greater than the thickness of the door leaf, and the door leaf is clamped between the two.

[0043] Installation method: Preferably, the concealed door leaf rotation limiter 4 is placed at the target location during the main building construction, and then concrete is poured to encase it within the main building structure. Alternatively, the main building can be cut after completion, the concealed door leaf rotation limiter 4 can be placed at the target location, and then concrete can be poured. To further increase structural strength, expansion bolts 122 can be driven into the main building structure first, and the concealed door leaf rotation limiter 4 can be fixed to the main building structure through the connection between the first base plate bolt hole 121 and the expansion bolt 122. Finally, concrete is poured to achieve double fixation of the expansion bolts and concrete.

[0044] Usage: When it is necessary to limit the door leaf, move the limiting body 31 away from the door stop body 21, and at the same time press down on the door stop body 21 to make it rotate out of the ground. Then release the limiting body 31 to make it spring back. At this time, the two first misaligned steps 211 of the door stop body 21 are respectively engaged with the top plate 11 and the top of the limiting body 31. Because the spring 34 applies sufficient elastic force to the limiting body 31, the limiting body 31 is tightly pressed against the door stop body 21 so that it will not fall into the ground. When it is not necessary to limit the door leaf, simply reverse the above steps. Example 2

[0045] like Figure 5 , Figure 6 As shown, the door leaf limiter set includes: a second base plate 5 and two sets of concealed door leaf rotation limiters 4. The second base plate 5 has a rectangular structure with its edges extending downwards to form sidewalls. The second base plate 5 is provided with four elongated holes 51, which are preferably oval-shaped holes.

[0046] The concealed door leaf rotation limiter 4 is fixed to the second base plate 5 by connecting the first base plate bolt hole 121 and the second base plate elongated hole 51 through the fixing bolt 123. The position of the fixing bolt 123 on the second base plate elongated hole 51 can be changed to adjust the spacing between the two sets of concealed door leaf rotation limiters 4 to accommodate door leaves of different thicknesses. The length of the fixing bolt 123 protruding from the bottom of the second base plate 5 does not exceed the height of the side wall of the second base plate 5, so that the second base plate 5 can remain horizontal when it is flat.

[0047] Compared with the solution in Example 1, the installation of the door leaf limiter set is more convenient and precise in terms of spacing adjustment. Since the two hidden door leaf rotation limiters 4 are connected by the second base plate to form an integrated structure, and the area of ​​the base plate is large enough and is covered by more concrete, the concrete is strong enough after pouring, and generally there is no need to use expansion bolts to increase the connection strength.

[0048] The door stop main body is used and hidden through the rotating mode, is clamped and limited through the staggered steps, has simple structure, good hiding property, can guarantee the ground to be flat when not being used, is safe and beautiful, is fixed through the concrete pouring, has large structural strength, can further increase the strength through the expansion bolts when necessary, has strong anti-impact capacity and long service life.

[0049] The above-mentioned embodiments and drawings are not limited to the product shape and style of the utility model, and any ordinary skilled person in the art can make appropriate changes or modifications, which should be considered as not departing from the patent category of the utility model.
