Integral limiting device for door with double-wedge shaped structure

Abstract

The invention relates to a monomeric limiter with a double-wedge shaped structure used for a door. The invention comprises a main body of the monomeric double-wedge shaped structure, the main body adotps a hexahedron, and is provided with a bottom surface, one face relative to the bottom surface is a first load bearing bevel face, one side of the bottom surface is upwardly and vertically extends out the lateral surface, one face relative to the lateral surface is a second load bearing bevel face, the distance between the small end of the first load bearing bevel face and the bottom surface is slightly smaller than the smallest gap between the lower rim of the door and the ground, and the distance between the big end of the second load bearing bevel face and the lateral surface is 1.5 to 3.5 times of the distance between the big end of the first load bearing bevel face and the bottom surface; the distance between the small end of the second load bearing bevel face and the lateral face is not smaller than the distance between the small end of the first load bearing bevel face and the bottom surface, and not larger than 0.9 time of the distance between the big end of the first load bearing bevel face and the bottom surface. The invention adopts the monomeric structure, the application range of the gap is wide, the invention is inserted in the gap between the lower rim of the door and the ground, the touch of the load bearing bevel face and the lower rim of the door prevents the closing of the door, and ensures that the door is under the required opening state, the cost is inexpensive, the use and the preservation are convenient, and the invention has no blocking to the passing.

Description

technical field [0001] The invention relates to a limiter for a door, especially a single limiter for a door with a double wedge structure, which can keep the door opened and closed by rotation in the required open state. Background technique [0002] To keep the door that rotates and opens and closes in the required open state, a wedge-shaped door limiter is pressed between the ground and the lower edge of the door, which must be adjusted in advance according to the size of the gap between the ground and the door. Get door limiters of at least two sizes. The previous methods are as follows: two wedge-shaped door restrictors can be stacked up and down, and the two are fitted through concave and convex buckles. When the size of the gap is small, any of them can be used separately. When the size of the gap is large, make the two overlap up and down as a door limiter, but when the two door limiters are separated, one of the components may be lost or forgotten to pack, which wi...

Problems solved by technology

[0007] However, in order to adapt to the use of larger or smaller gaps between the ground and the door, the "door limiter" scheme and the above-mentioned earlier schemes all need to be equipped with at least two wedge-shaped members, and there must be a gap between these members. Joint connection, especially the "door limiter" scheme includes a base with complex shapes, a door stopper installed on the inclined upper part of the base, and a rotating carrier for the door and the large head of the base at the joint part At least one hinge holding mechanism is provided to keep the rotating carrier for the door in a low position or a high position relative to the base, and its structure is relatively complicated, which increases the manufacturing cost
