Description

Technical Field

[0001] The utility model relates to the field of furniture, in particular to a structure for preventing fingers from being pinched by a wooden door. Background Art

[0002] During the use of an indoor wooden door, when the door leaf opens and closes, there is a gap of only 3 millimeters at the minimum, and it is easy to accidentally pinch or maim a child's finger, which is likely to cause a tragedy. To avoid pinching by the door leaf, an anti-pinch strip needs to be installed on the wooden door. In the prior art, due to the existence of hinges on the door leaf, the installation position of the anti-pinch strip is restricted, the protection range is not large enough, and the adaptability to protecting people of different heights is poor. For example, children cannot be protected because there is no anti-pinch strip at a lower position.

[0003] For example, in the "Fireproof Door with Anti-Pinching Function" disclosed in the Chinese patent document, the publication number is CN217681415U, which includes a door frame. One side of the inner cavity of the door frame is connected with a fireproof door body through a hinge. Anti-pinching grooves are symmetrically opened on both sides of the fireproof door body. A windshield cotton strip is fixedly arranged in the inner cavity of the anti-pinching groove, and the hinge is a hydraulic hinge. The disadvantage of this patent is that the setting position of the anti-pinching groove is restricted by the hinge, resulting in a small anti-pinching protection range and incomplete protection for people of different heights. Summary of the Utility Model

[0004] The utility model aims to overcome the problem of insufficient anti-pinching protection range of the door leaf in the prior art, and provides a structure for preventing fingers from being pinched by a wooden door, which can improve the anti-pinching protection range and ensure that people of different heights can achieve anti-pinching protection at positions where they may touch.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The utility model provides a structure for preventing fingers from being pinched by a wooden door, which includes a segmented anti-pinching component. The segmented anti-pinching component includes a first anti-pinching strip located outside the door leaf, a second anti-pinching strip located between the door leaf and the door frame, and a third anti-pinching strip located inside the door leaf. The second anti-pinching strip includes a plurality of anti-pinching segments, and an installation opening is formed between two adjacent anti-pinching segments.

[0007] In this application, by segmenting the second anti-pinching strip, it is possible to avoid the hinge position, preventing the installation position of the anti-pinching strip from being restricted due to the hinge. Through the first anti-pinching strip and the third anti-pinching strip, on the one hand, they can assist in anti-pinching, and on the other hand, they can ensure the unity and integrity of the appearance of the door frame edge. Moreover, since the space between the door leaf and the door frame is almost completely filled with the anti-pinching strip, the sound insulation and noise reduction effect is better.

[0008] Preferably, an outer doorframe trim is installed on the outer side of the doorframe. The first anti-pinch strip is installed on the outer doorframe trim by a nail gun, and the end of the nail gun is nailed into the doorframe.

[0009] Preferably, the first anti-pinch strip includes a skeleton, and the nail gun is installed on the skeleton. This structure can improve the reliability of the fixation of the first anti-pinch strip.

[0010] Preferably, a first fixing opening is provided between the doorframe trim and the doorframe. The second anti-pinch strip includes a plug-in member adapted to be installed in the first fixing opening.

[0011] Preferably, a second fixing opening is provided on the doorframe. The second anti-pinch strip includes a plug-in member adapted to be installed in the second fixing opening.

[0012] Preferably, a third fixing opening is provided on the doorframe. The third anti-pinch strip includes a plug-in member adapted to be installed in the third fixing opening.

The third anti-pinch strip 6 can be quickly installed on the door frame 1 through the plugging of the plug-in part 10 with the third fixing port 14 and the fourth fixing port 15.

[0030] The plug-in part 10 includes an installation part and a plugging part, and the plugging part is provided with an elastic part. The elastic part includes a plug board extending into the fixing port and elastic plates located on both sides of the plug board. An acute angle is formed between the elastic plates and the plug board. When the plug board enters the fixing port, the included angle between the plug board and the elastic plates decreases, and thus the generated elastic force causes the elastic part to be stuck in the fixing port.

[0031] A hinge cushion block 16 is installed at the hinge installation port. The hinge cushion block 16 is also installed on the door frame 1 by a nail gun 8. The thickness of the hinge cushion block 16 is the same as that of the second anti-pinch strip 5. One installation surface of the hinge is installed on the hinge cushion block 16, and the other installation surface is installed on the door leaf 2.

[0032] In addition, a door lock 3 is installed on the door leaf 2. The door lock 3 is located on the opposite side of the hinge installation side.
