Description

Technical Field

[0001] The utility model relates to the technical field of clean room sliding doors, in particular to a sliding door used in a clean room. Background Art

[0002] A clean room is a room specially designed to remove pollutants such as particles, harmful air, and bacteria from the air within a certain space, and to control the indoor temperature, cleanliness, indoor pressure, airflow speed and distribution, noise vibration, lighting, and static electricity within a certain required range. That is, no matter how the external air conditions change, the room can maintain the characteristics of the cleanliness, temperature, humidity, and pressure required by the original setting. The main function of a clean room is to control the cleanliness, temperature, and humidity of the atmosphere that the product contacts, so that the product can be produced and manufactured in a good environment. We call this space a clean room. According to international practice, the dust-free purification level is mainly determined by the number of particles with a diameter greater than the classification standard per cubic meter of air. That is to say, the so-called dust-free is not 100% dust-free, but controlled in a very small unit. Of course, the particles that meet the dust standard in this standard are already very small compared to the common dust we see, but for optical structures, even a little dust will have a very large negative impact, so in the production of optical structure products, dust-free is an inevitable requirement. The utility model is a sliding door for a clean room.

[0003] When the sliding door of the existing clean room is closed, there is still a certain gap between the bottom of the sliding door and the ground. The gap at the bottom of the sliding door provides space for dust or germs to invade, which will cause harm to the internal environment of the clean room. Utility Model Content

[0039] A hanging rail 14 is fixed on the door frame 1, a movable door panel 2 is installed at the lower end of the hanging rail 14, and the lower end of the connecting plate 1312 is installed on the movable door panel 2 by bolts.

[0040] In the present disclosure,

[0041] The bottom of the movable door panel 2 is provided with a bottom groove 21, the bottom groove 21 is a rectangular groove, and a fixing rod 22 is fixed in the bottom groove 21, and a first elastic piece 23 is sleeved on the fixing rod 22, and the first elastic piece 23 is an arc-shaped structure. The inner walls of the front and rear ends of the bottom groove 21 are provided with waist-shaped sliding grooves 24, and a sliding seat 241 is slidable between the two sets of waist-shaped sliding grooves 24. A second elastic piece 25 is hinged on the sliding seat 241, and the second elastic piece 25 is an arc-shaped structure. An extrusion rod 242 is fixed on the sliding seat 241, and a through hole is provided on the movable door panel 2. The pressure rod 242 moves in the through hole on the movable door panel 2, and its function is: when the left side of the movable door panel 2 collides with the door frame 1, the squeezing button 243 is squeezed to the right side, and the second spring piece 25 is squeezed at this time, and the second spring piece 25 approaches the first spring piece 23. At this time, the sweeping strip 26 moves downward, so that the silicone strip 261 at the lower end of the sweeping strip 26 is in close contact with the lower end of the door frame 1, so that the gap between the movable door panel 2 and the lower end of the door frame 1 is completely blocked, so that the clean room forms a completely sealed space, ensuring the clean state of the space inside the clean room.

[0042] Embodiment 2, based on embodiment 1,

[0043] The second spring piece 25 and the first spring piece 23 are made of stainless steel, and the lower ends of the first spring piece 23 and the second spring piece 25 are connected with a sweeping strip 26, and the lower end of the sweeping strip 26 is fixed with a silicone strip 261, which has the following functions: the second spring piece 25 and the first spring piece 23 are made of stainless steel to produce a large elastic deformation, and mechanical work or kinetic energy can be converted into deformation energy. After unloading, the deformation disappears and returns to its original state, converting the deformation energy into mechanical work or kinetic energy, and has a high elastic limit, fatigue limit, impact toughness, and good temperature resistance and corrosion resistance. The silicone strip 261 has a certain elasticity, which improves the sealing on the one hand and reduces the damage to the bottom of the door frame 1 on the other hand.

[0044] Embodiment 3, based on Embodiment 1 and Embodiment 2,

[0045] An external thread is provided on the squeezing rod 242, and a squeezing button 243 is threadedly screwed on the squeezing rod 242, and an anti-loosening spring 244 is installed on the squeezing rod 242, whose function is: when the squeezing button 243 is rotated outward, the squeezing button 243 extends out of the sliding door panel 2 body end and becomes longer. When the squeezing button 243 is squeezed, the sliding seat 241 moves a distance of the side length, so that the force on the second elastic piece 25 increases, and the downward blocking distance of the sweeping strip 26 increases, and vice versa, so that the sweeping strip 26 blocks the entire gap. By adjusting the squeezing button 243, the sliding door can be suitable for different door gap sizes, and the setting of the anti-loosening spring 244 makes the squeezing button 243 have a certain pressure and will not rotate autonomously.

[0046] The working principle of this embodiment is as follows: when in use, the motor 133 is operated to rotate the connecting belt 135, and the movable door panel 2 is driven to close through the connecting belt 135. When the left side of the movable door panel 2 collides with the door frame 1, the squeezing button 243 is squeezed to the right side. At this time, the second spring piece 25 is squeezed, and the second spring piece 25 approaches the first spring piece 23. At this time, the sweeping strip 26 moves downward, so that the silicone strip 261 at the lower end of the sweeping strip 26 is in close contact with the lower end of the door frame 1, so that the gap between the movable door panel 2 and the lower end of the door frame 1 is completely blocked, so that the clean room forms a completely sealed space, ensuring the clean state of the space inside the clean room. The silicone strip 261 has a certain elasticity, which improves the sealing performance on the one hand, and reduces the damage to the bottom of the door frame 1 on the other hand. The squeezing button 243 is rotated outward, The squeezing button 243 extends out of the main body end of the movable door panel 2 and becomes longer. When the squeezing button 243 is squeezed, the sliding seat 241 moves a distance of the side length, so that the force on the second spring piece 25 increases, and the downward blocking distance of the sweeping strip 26 increases, and vice versa, so that the sweeping strip 26 blocks the entire gap. By adjusting the squeezing button 243, the sliding door can be suitable for different door gap sizes, and the setting of the anti-loosening spring 244 makes the squeezing button 243 have a certain pressure and will not rotate autonomously. When the movable door panel 2 is opened, the squeezing of the squeezing button 243 disappears, and the second spring piece 25 rebounds, so that the sweeping strip 26 is retracted into the bottom groove 21. During the movement of the movable door panel 2, the sweeping strip 26 will not rub against the bottom of the door frame 1, causing wear of the sweeping strip 26 or the door frame 1.
