Embodiment 1

[0051] Such as Figure 2 to Figure 5 As shown, there is a door gap 100 between the door hinge side 51 and the door frame 2 , and the protective strip 1 covers the door gap 100 . One side of the protective strip 1 is fixed on the door frame 2 by a hinge 3, and the hinge 3 (ie, the hinge) can rotate. The other side of protective strip 1 is equipped with roller 4, and roller 4 rides on the door leaf 5, can roll along the surface of door leaf 5. In order to ensure that the roller 4 rolls along the door leaf all the time, a spring 6 is set between the protection strip 1 and the hinge 3, one end of the spring 6 is connected to the hinge, and the other end is connected to the inside of the protection strip 1. The spring 6 is in a tensioned state, and under the action of the spring 6, the roller 4 is always in a state of being attached to the door leaf 5.

[0052] When the door leaf 5 is closed, see Figure 4 As shown, the distance between the roller 4 and the door gap 100 is the f...

Embodiment 2

[0054] Such as Figure 6As shown, in this embodiment, one side of the protective strip 1 is connected to the door frame 2 through the spring hinge 7, and the other side of the protective strip 1 is equipped with a roller 4, which is connected to the door leaf 5 by sliding through the roller 4, and is connected by the spring hinge 7 itself. Elasticity ensures that roller 4 contacts with door leaf 5 all the time. Spring hinge 7 is the spring hinge usually used in the spring door. The spring hinge 7 has such Figure 6 Reset function shown in counterclockwise direction. The roller 4 on the protective strip 1 rides on the door leaf 5 and can roll on the surface of the door leaf 5. Under the effect of the spring hinge 7, the roller 4 is always attached to the door leaf 5.

[0055] When the door leaf 5 was closed, the distance between the roller 4 and the door slit 100 was the furthest; The surface of the door remains in close contact, so that the door gap 100 is always in a cove...

Embodiment 3

[0057] Such as Figure 7 and Figure 8 As shown, this embodiment is: one side of the protection strip 1 is connected with the door frame 2 through the hinge 3, the other side of the protection strip 1 is installed with a roller 4, and the first magnet 81 is provided at the place where the roller 4 is installed on the protection strip 1, and the door leaf 5 Paste or embed the second magnet 82 or iron sheet that is attracted to the first magnet 81 along the rolling track of the roller 4 . In this embodiment, under the action of the magnetic force between the first magnet 81 and the second magnet 82 or the iron sheet, the roller 4 is always in a state of being attached to the door leaf 5 .

[0058] When the door leaf 5 was closed, the distance between the roller 4 and the door gap 100 was the furthest; Or the magnetic force between the iron sheets is always in contact with the surface of the door leaf 5, so that the door gap 100 is always in a shielded state. In this way, peop...

Abstract

The invention provides an anti-pinch door crack protection device for blocking a crack between the rotation shaft side of a door sash and a door frame. The anti-pinch door crack protection device comprises a protection strip for blocking the door crack, wherein one side of the protection strip is in hinged connection with the door frame, and the other side of the protection strip is in contact sliding connection with the door sash. During door opening and closing, the protection strip always blocks the door crack, and effective and reliable protection can be provided.

Description

technical field [0001] The invention relates to the technical field of door and window engineering involved in construction engineering, in particular to an anti-pinch door seam protection device. Background technique [0002] Casement doors are widely used in modern buildings. The side of the hinge of the side-hung door is equipped with a hinge and is connected with the door frame. When the door is opened, a seam will be formed between the side of the hinge of the door leaf and the door frame. When adults or children accidentally put their fingers in the door gap and the door is closed by other people or under the effect of environmental factors such as wind, due to the leverage effect, it is very easy to cause serious injury to the fingers. [0003] Chinese Invention Patent (Patent No.) ZL201310286473.8 proposes a door gap anti-pinch transposition, which uses an infrared sensor to detect whether someone is at the door gap, and uses a circuit to control the insertion of ba...
