Abstract
Description
Technical Field
[0001] The utility model relates to the field of clean room doors, in particular to a sweeping strip with plugs at both ends of the clean room door. Background Art
[0002] The cleanroom door we are talking about is a door that is easy to clean, self-cleaning and antibacterial, and has excellent airtightness. It is suitable for various occasions with high airtightness requirements, such as various hospital construction, biomedical laboratories, food and beverage processing plants, equipment and electronics factories, etc. The bottom of the cleanroom door usually needs to be equipped with a lifting sweeping strip to prevent leakage or infiltration of internal and external substances (rainwater, air, dust, etc.), and can avoid or reduce damage caused by mechanical vibration and impact, thereby achieving sealing, sound insulation, heat insulation and earthquake resistance, etc., and better ensuring airtightness. The sweeping strip has an outer aluminum material and an inner aluminum material. The inner aluminum material is arranged in the outer aluminum material. There is no sealing device on both sides of the inner aluminum material of the existing sweeping strip, which results in dust and other foreign matter easily entering the inner aluminum material from the openings on both sides of the inner aluminum material when in use. Utility Model Content
[0003] The utility model solves the problem that dust or foreign matter is easily entered into the sweeping strip of the existing purification door.
[0004] The technical solution adopted by the utility model is: a sweeping strip with plugs at both ends of a purification door, comprising an outer aluminum material and an inner aluminum material, the outer aluminum material having a first mounting portion and a second mounting portion, the first mounting portion and the second mounting portion being interconnected, first plugs being arranged at both ends of the first mounting portion, wherein a copper column is arranged in the first plug close to one end of the door frame, an inner aluminum material is arranged in the second mounting portion, second plugs are arranged at both ends of the inner aluminum material, and a rubber strip is arranged at the bottom of the inner aluminum material.
[0005] Furthermore, a slope structure is provided on the top of the side surface of the second plug.
[0006] Furthermore, the second plug is provided with a raised bone position at the bottom of the inclined structure.
[0007] Furthermore, both sides of the outer aluminum material are fixed to the bottom of the door leaf by screws.
[0008] Compared with the prior art, the utility model has the following beneficial effects: second plugs are provided at both ends of the inner aluminum material, the inner holes at both ends of the inner aluminum material cannot be seen through the second plugs, the appearance is more beautiful, and the inner holes at both ends of the inner aluminum material are blocked to prevent dust or foreign matter from entering the inner aluminum material.

[0015] like Figures 1 to 5 The invention discloses a sweeping strip with plugs at both ends of a purification door, comprising an outer aluminum material 10 and an inner aluminum material 20, wherein the outer aluminum material 10 has a first mounting portion 11 and a second mounting portion 12, wherein the first mounting portion 11 and the second mounting portion 12 are interconnected, and first plugs 13 are provided at both ends of the first mounting portion 11, wherein a copper column 14 is provided in the first plug 13 close to one end of the door frame.
[0016] The second mounting portion 12 is provided with an inner aluminum material 20 , both ends of the inner aluminum material 20 are provided with second plugs 21 , and a rubber strip 22 is provided at the bottom of the inner aluminum material 20 .
[0017] When in use, the outer aluminum material 10 is fixed to the bottom of the door leaf on both sides by screws 101, and a pushing assembly (not shown in the figure) is provided in the first mounting portion 11, which is respectively in contact with the inner aluminum material 20 and the copper column 14. When the door leaf and the door frame are closed, the copper column 14 on one side of the door leaf will be in contact with the door frame and retracted into the door leaf. At this time, the copper column 14 drives the pushing assembly to push the inner aluminum material 20 downward, so that the rubber strip 22 of the inner aluminum material 20 is in contact with the ground to form a seal to prevent dust and other foreign objects from entering the room. Second plugs 21 are provided at both ends of the inner aluminum material 20. The inner holes at both ends of the inner aluminum material 20 cannot be seen through the second plug 21, which makes the appearance more beautiful, and blocking the inner holes at both ends of the inner aluminum material 20 can prevent dust or foreign objects from entering the inner aluminum material.
[0018] How the pushing component in the outer aluminum material 10 pushes the inner aluminum material 20 to drive the rubber strip 22 to move up and down to form a seal with the ground is a well-known technical solution in the field of cleanroom doors and will not be described in detail here.
[0019] A slope structure 201 is provided on the top of the side of the second plug 21. When the door leaf and the door frame are opened, the inner aluminum material 20 drives the rubber strip 22 to move upward to retract the outer aluminum material 10. The slope structure 201 of the second plug 21 has a guiding function to prevent rebound and jamming.
[0020] The second plug 21 is provided with a raised bone position 202 at the bottom of the inclined structure 201. When the inner aluminum material 20 moves up and down in the door leaf, the bone position 202 of the second plug 21 moves in the outer frame of the door leaf, reducing the area when the side of the second plug 21 contacts the outer frame of the door leaf, thereby reducing resistance.
