Description

Technical Field

[0001] This utility model belongs to the technical field of door bottom seals, and provides a concealed magnetic door bottom seal that improves user comfort and reduces usage costs. Background Technology

[0002] Door bottom seals are required in spaces with high requirements for sound insulation, light blocking, heat preservation, or hygiene. Existing door bottom seals generally consist of a housing, a drive mechanism inside the housing, and a recessed plate connected to the drive mechanism. When the door is closed, the drive mechanism moves the recessed plate out of the housing to complete the sealing action. When the door is opened, the recessed plate rises under the drive mechanism and retracts into the housing. This type of door bottom seal uses a motor to drive the recessed plate up and down, requiring regular maintenance of the motor and the power supply, resulting in high maintenance costs and poor user comfort. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a concealed magnetic door bottom seal that improves user comfort and reduces usage costs.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model provides a concealed magnetic door bottom seal, including a housing for fixed connection with a door leaf, a drive mechanism located on the housing, and a sealing mechanism connected to the drive mechanism, wherein: a limiting countersunk platform and a limiting plate are provided on the inner wall of the inner cavity of the housing, an installation cavity b is formed between the limiting countersunk platform and the limiting plate, and an installation cavity a is formed between the limiting plate and the top plate of the housing, and the height of the installation cavity a is lower than the height of the installation cavity b;

[0006] The drive mechanism includes magnetic strip a, magnetic strip b, magnetic strip c and magnetic strip d, with magnetic strip a located in mounting cavity a and magnetic strip d fixed to the floor directly below the door when it is closed;

[0007] The sealing mechanism is a rubber sleeve structure, which has independent mounting cavities c and d. The magnetic strip b is located in the mounting cavity c, and the magnetic strip c is located in the mounting cavity d.

[0008] The magnetic force of magnetic stripe d is greater than that of magnetic stripe a;

[0009] When in use, with the door closed, magnetic strip d attracts magnetic strip c and, driven by the sealing mechanism, moves magnetic strip b downward. Magnetic strip b is positioned on the limiting platform. After magnetic strip d and magnetic strip c are in contact, they seal the bottom of the door. When the door is opened by external force, magnetic strip d and magnetic strip c separate. Magnetic strip b, under the magnetic attraction of magnetic strip a, moves the sealing mechanism upward and retracts into the inner cavity of the outer shell. At this time, magnetic strip b and magnetic strip a are magnetically attracted as one.

[0010] To prevent the magnetic strips from colliding and being damaged during the opening and closing of the door, the above solution further includes: the sealing mechanism having a buffer cavity a and a buffer cavity b, wherein the buffer cavity a is located between the mounting cavity c and the mounting cavity d, and the buffer cavity b is located below the mounting cavity d.

[0011] To further improve the sealing effect, in the above solution, the bottom of the sealing mechanism is provided with a sealing part integrated therewith.

[0012] To prevent the limiting plate from affecting the magnetic attraction between magnetic strip a and magnetic strip b, the above solution further includes: the limiting plate has a hollowed-out portion in the middle.

[0013] To ensure the service life of the magnetic strip a, the above solution further includes: the magnetic strip a is located in a buffer sleeve, which is located in the mounting cavity a.

[0014] To effectively ensure the magnetic attraction effect of magnetic stripe d to magnetic stripe c, and to effectively ensure the magnetic attraction effect of magnetic stripe a to magnetic stripe b, in the above scheme, the magnetic poles of the opposite plates of magnetic stripe b and magnetic stripe c are further reversed.

[0015] To ensure the service life of the magnetic strip d, in the above solution, the magnetic strip d is further located in the inner cavity of the anti-kick component.

[0016] To ensure the kick-proof effect of the anti-kick component, in the above solution, the cross-section of the anti-kick component is an isosceles trapezoid.

[0017] To facilitate the secure installation of the outer casing on the bottom end face of the door leaf, the above solution further includes: a connecting base plate integrally formed therewith is provided on the two outer walls of the outer casing; in use, the outer casing is embedded in a matching groove located on the bottom end face of the door leaf.

[0018] To facilitate the loading and unloading of the outer casing, the above solution further includes: the outer end of the connecting base plate has an integral protective plate, which forms an installation groove with the connecting base plate and the outer wall of the outer casing.

[0019] The beneficial effects of this utility model are: the extension and retraction of the sealing mechanism is achieved through the interaction of magnetic strips a, b, c and d, eliminating the need for additional power and reducing the cost of use; and the drive mechanism no longer requires maintenance, improving user comfort.
