Description

Technical Field

[0001] This utility model belongs to the field of window sealing technology, and in particular relates to a multi-seal structure between a threshold and a door leaf. Background Technology

[0002] To facilitate opening and closing, a gap is usually left between the bottom of the door and the top of the threshold, making it difficult to ensure a tight seal between the door and the threshold. Outdoor air can flow into the room through the gap, reducing the window's insulation performance. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, solve or at least alleviate the problem of poor sealing between the door leaf and the threshold, and provide a multi-seal structure between the threshold and the door leaf.

[0004] This utility model is achieved through the following technical solution:

[0005] A multi-seal structure between a threshold and a door leaf is disclosed. The threshold includes an inner threshold and an outer threshold, and the door leaf includes an inner leaf and an outer leaf. The door panel is fixedly installed between the inner leaf and the outer leaf. A gap is left between the lower end of the door leaf and the upper end of the threshold. Thermal insulation strips are provided between the inner and outer thresholds and between the inner and outer leaves. The thermal insulation strips include a threshold strip, a door leaf strip, and a door leaf compensating plastic material. The height of the outer threshold is higher than that of the inner threshold. The threshold strip is located on the side of the outer threshold that is higher than the inner threshold and faces the inner threshold. The door leaf compensating plastic material is fitted into the lower end of the outer leaf and extends downwards from the door leaf, abutting against the threshold strip. A downwardly extending baffle is provided on the inner side of the lower end of the inner leaf. The baffle is located inside the inner threshold. The door leaf strip is positioned at the lower part of the baffle facing the inner threshold and abuts against the inner wall of the inner threshold.

[0006] To further realize this utility model, the following technical solutions may be preferred:

[0007] Preferably, a sealing section is provided at the upper end of the side of the sill strip away from the outer threshold. The sealing section is flat and is arranged along the length of the sill strip. The upper end of the sealing section is integrated with the sill strip, and the lower end is inclined towards the inside of the sill strip. An angle is formed between the sealing section and the inner wall of the sill strip. The angle is α, and α is 30-60°.

[0008] Preferably, the door leaf compensation plastic material includes an integrally formed fitting section and an abutting section. The fitting section is fitted into the lower inner side of the outer leaf, and the abutting section is a vertically arranged flat plate with its lower part abutting against the sealing section.

[0009] Preferably, the door leaf compensation plastic material further includes an integrally formed support section, which is a horizontally arranged flat plate, and the upper surface of the support section is attached to the lower end face of the heat insulation strip at the bottom of the inner and outer leaves.

[0010] Preferably, the door leaf compensation plastic material further includes an integrally formed reinforcing section, which is a flat plate arranged parallel to the abutting section. The upper ends of the abutting section and the reinforcing section are respectively connected to the lower front and rear parts of the supporting section, and the height of the reinforcing section is less than the height of the abutting section.

[0011] Preferably, the upper end face of the heat insulation strip located above the inner and outer sills is flush with the upper end face of the inner sill, and the section of the sill strip away from the outer sill is attached to the upper end face of the heat insulation strip.

[0012] Preferably, the door panel sealing strip includes a rear positioning strip and a front sealing bladder, wherein the positioning strip is made of a rigid material and the sealing bladder has a flexible hollow bladder structure.

[0013] The beneficial effects of this utility model through the above technical solution are:

[0014] This utility model achieves multiple seals between the door leaf and the threshold by using a threshold rubber strip and a door leaf rubber strip. The outer threshold is higher than the inner threshold to avoid interference when the door leaf is opened and closed. At the same time, the door leaf compensation plastic material achieves a seal between the door leaf and the threshold rubber strip.

[0015] The door sill strip and the sealing section form an angle. When the sealing section is pressed against the door leaf's compensating plastic material, it can undergo a certain deformation. At the same time, the sealing bladder at the front of the door leaf strip can also deform under pressure, ensuring that both seals can maintain a good sealing effect. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Example 1:

[0025] like Figures 1-5 As shown, a multi-seal structure between a threshold and a door leaf is disclosed. The threshold includes an inner threshold 1 and an outer threshold 2, and the door leaf includes an inner leaf 3 and an outer leaf 4. The door leaf is fixedly installed between the inner leaf 3 and the outer leaf 4. A gap is left between the lower end of the door leaf and the upper end of the threshold. Heat insulation strips 5 are provided between the inner threshold 1 and the outer threshold 2, and between the inner leaf 3 and the outer leaf 4. The heat insulation strips 5 include a threshold rubber strip 6, a door leaf rubber strip 7, and a door leaf compensating plastic material 8. The height of the outer threshold 2 is higher than that of the inner threshold 1. The threshold rubber strip 6 is located on the side of the outer threshold 2 that is higher than the inner threshold 1 and faces the inner threshold 1. The door leaf compensating plastic material 8 is fitted into the lower end of the outer leaf 4 and extends downwards from the door leaf, abutting against the threshold rubber strip 6. A downwardly extending baffle is provided on the inner side of the lower end of the inner leaf 3. The baffle is located inside the inner threshold 1. The door leaf rubber strip 7 is positioned at the lower part of the baffle facing the inner threshold 1 and abuts against the inner wall of the inner threshold 1.

[0026] Multiple seals are achieved between the door leaf and the threshold through the threshold rubber strip 6 and the door leaf rubber strip 7. The outer threshold 2 is higher than the inner threshold 1 to avoid interference when the door leaf is opened and closed. At the same time, the door leaf compensation plastic material 8 is used to achieve a seal between the door leaf and the threshold rubber strip 6.

[0027] A sealing section 9 is provided at the upper end of the side of the door sill strip 6 away from the outer sill 2. The sealing section 9 is flat and is arranged along the length of the door sill strip 6. The upper end of the sealing section 9 is integrated with the door sill strip 6, and the lower end is inclined towards the inside of the door sill strip 6. An angle is formed between the sealing section 9 and the inner wall of the door sill strip 6. The angle is α, and α is 30-60°.

[0028] The door panel rubber strip 7 includes a rear positioning strip 701 and a front sealing bladder 702. The positioning strip 701 is made of a rigid material, and the sealing bladder 702 has a flexible hollow bladder structure.

[0029] The door sill strip 6 and the sealing section 9 form an angle. When the sealing section 9 is pressed by the door leaf compensating plastic material 8, it can undergo a certain deformation. At the same time, the sealing bladder 702 at the front of the door leaf strip 7 can also deform under pressure, which can ensure that both seals can maintain a good sealing effect.

[0030] In order to optimize the product structure, in this embodiment, the door leaf compensation plastic material 8 includes an integrally formed fitting section 801 and abutting section 802. The fitting section 801 is fitted into the lower inner side of the outer leaf 4, and the abutting section 802 is a vertically arranged flat plate, with the lower part of the abutting section 802 abutting to the sealing section 9.

[0031] In order to ensure the stability of the position of the heat insulation strip 5 through the door leaf compensation plastic material 8, the door leaf compensation plastic material 8 also includes an integrally formed support section 803. The support section 803 is a horizontally arranged flat plate, and the upper surface of the support section 803 is attached to the lower end face of the heat insulation strip 5 at the bottom of the inner door 3 and the outer door 4.

[0032] To ensure the strength of the door leaf compensation plastic material 8 and prevent deformation, the door leaf compensation plastic material 8 also includes an integrally formed reinforcing section 804. The reinforcing section 804 is a flat plate arranged parallel to the abutting section 802. The upper ends of the abutting section 802 and the reinforcing section 804 are respectively connected to the lower front and rear parts of the supporting section 803. The height of the reinforcing section 804 is less than the height of the abutting section 802.

[0033] To prevent outdoor air from entering the room through the gap between the threshold and the heat insulation strip 5, the upper end face of the heat insulation strip 5 located on the upper part of the inner threshold 1 and the outer threshold 2 is flush with the upper end face of the inner threshold 1, and a section of the threshold adhesive strip 6 away from the outer threshold 2 is attached to the upper end face of the heat insulation strip 5.

[0034] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
