Abstract
Description
Technical Field
[0001] The utility model belongs to the purification field, especially the purification door field, and particularly relates to a purification door with a magnetic lock structure. Background Art
[0002] A clean room refers to a relatively airtight space in which parameters such as air cleanliness, temperature, humidity, pressure, and noise are controlled as required. Among them, the purification door is a barrier isolating the outside from the interior. Traditional purification doors use door closers to close, but due to the pressure difference between the inside and outside of the room, a pure door closer cannot completely close the purification door, resulting in poor sealing performance. Content of the Utility Model
[0003] The purpose of the utility model is to provide a purification door with a magnetic lock structure.
[0004] To achieve the above purpose, the utility model provides the following technical solutions:
[0005] A purification door with a magnetic lock structure includes a door frame and a door leaf. The door frame includes a first side frame, a second side frame, and a top frame connecting the first side frame and the second side frame. The door leaf is hinged to the second side frame through a hinge. On the sides of the first side frame and the second side frame facing the door leaf, there are protruding edges. On the side of the door leaf facing the protruding edges, there are grooves corresponding to the protruding edges. A magnetic structure is arranged between the door leaf and the first side frame, and the magnetic structure includes magnetic blocks arranged on the door leaf and the first side frame.
[0006] Preferably, lining plates are welded on both the door leaf and the first side frame, and through holes for screws to pass through are provided on both the lining plates and the magnetic blocks.
[0007] Preferably, a notch for placing the magnetic block is provided between the door leaf and the first side plate. The lining plate includes a bottom plate integrally formed and welding plates on both sides of the bottom plate, and the side of the welding plate facing the bottom plate is inclined.
[0008] Preferably, an adjusting cushion block is arranged between the lining plate and the magnetic block.
[0009] Preferably, partition strips corresponding to the protruding edges are arranged at the grooves on both sides of the door leaf.
[0010] Preferably, a handle and a transparent visual window are arranged on the door leaf.
[0011] The beneficial effects of the utility model are as follows: The magnetic force between the magnetic blocks can be used to attract each other, so as to overcome the pressure difference between the inside and outside of the room and completely close the purification door, increasing the sealing performance. The adjusting cushion block can adjust the distance between the two magnetic blocks, so that when the purification door is completely closed, the two magnetic blocks fit more closely. The sealing performance can be further increased through the partition strips. Brief Description of the Drawings

Detailed Description of the Preferred Embodiments
[0017] The technical solutions of this patent will be further described in detail below in conjunction with the specific embodiments.
[0018] As Figures 1 to 4 shown, a purification door with a magnetic attraction door lock structure of the present utility model includes a door frame 12 and a door leaf 10. The door frame 12 includes a first side frame 122, a second side frame 124, and a top frame 126 connecting the first side frame 122 and the second side frame 124. The door leaf 10 is hinged to the second side frame 124 through a hinge 14. Convex edges 18 protrude from the sides of the first side frame 122 and the second side frame 124 facing the door leaf 10. Grooves 16 corresponding to the convex edges 18 are provided on the side of the door leaf 10 facing the convex edges 18. A magnetic attraction structure is provided between the door leaf 10 and the first side frame 122. The magnetic attraction structure includes magnetic attraction blocks 24 provided on the door leaf 10 and the first side frame 122;
[0019] The convex edges 18 and the grooves 16 cooperate to limit the door leaf 10 when closing the door, making the door leaf 10 fit more closely with the door frame 12. Due to the pressure difference between inside and outside the room, a pure door closer cannot completely close the door, resulting in poor sealing performance. The magnetic attraction structure can solve this problem.
[0020] Lining plates 20 are welded on both the door leaf 10 and the first side frame 122. Through holes for the screws 26 to pass through are provided on both the lining plates 20 and the magnetic attraction blocks 24;
[0021] The lining plates 20 are welded on the door leaf 10 and the first side frame 122. The screws 26 are passed through the magnetic attraction blocks 24 and the lining plates 20 and are threadedly connected with nuts 28 to fix the magnetic attraction blocks 24 on the lining plates 20, preventing the magnetic attraction blocks 24 from shifting during use.
[0022] A notch for placing the magnetic attraction block 24 is formed between the door leaf 10 and the first side plate. The lining plate 20 includes a bottom plate formed integrally and welding plates located on both sides of the bottom plate. The side of the welding plate facing the bottom plate is inclined.
[0023] The side of the welding plate facing the bottom plate is inclined, so that the distance between two corresponding bottom plates is larger, which is convenient for installing larger magnetic blocks and increasing the magnetic force.
[0024] An adjusting cushion block 22 is arranged between the lining plate 20 and the magnetic attraction block 24. The cushion block 22 has elasticity and flexibility. By tightening the screw, the distance between the magnetic attraction block 24 and the lining plate 20 can be adjusted, so as to adjust the distance between the two magnetic attraction blocks 24, so that the two magnetic attraction blocks 24 are as close as possible when the door is closed.
[0025] Arranging the cushion block 22 between the magnetic attraction block 24 and the lining plate 20 can adjust the distance, so that the two magnetic attraction blocks 24 are as close as possible when the door is closed.
[0026] Partition strips corresponding to the convex edges 18 are arranged at the grooves 16 on both sides of the door leaf 10. The sealing performance can be improved through the partition strips.
[0027] A handle 30 and a transparent visual window 32 are arranged on the door leaf 10.
[0028] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms.
