[0026] The present invention will be further described in detail below with reference to the accompanying drawings.
[0027] like Figure 1 , Figure 2 As shown, a cleanroom structure for precision instruments includes a cleanroom 1, a cloakroom 2, an inner switch door 3, an outer switch door 4, a connecting frame 5, and a drive mechanism 6.
[0028] like Figure 2 , Figure 3 As shown, a cleanroom 1 has an inner corridor 11 on one side, and a cloakroom 2 has an outer corridor 21 connecting the inner corridor 11 on one side. An inner sliding door 3 is slidably connected to the inner corridor 11, and an outer sliding door 4 is slidably connected to the outer corridor 21.
[0029] like Figure 2 , Figure 3 As shown, the connecting frame 5 is disposed between the inner switch door 3 and the outer switch door 4, and a lighting lamp 51 is provided on the connecting frame 5 for illumination. A retaining ring 7 is provided at the connection position between the inner corridor 11 and the outer corridor 21 to abut against the inner switch door 3 and the outer switch door 4, thereby limiting the inner switch door 3 and the outer switch door 4.
[0030] like Figure 2 , Figure 3 As shown, the drive mechanism 6 is used to control the reciprocating sliding of the connecting frame 5. The drive mechanism 6 includes a rotating shaft 61, a reducer 62, a gear 63, and a rack 64. The rotating shaft 61 is horizontally rotatably connected to the connection position of the inner corridor 11 and the outer corridor 21. The reducer 62 is used to control the rotation of the rotating shaft 61. The gear 63 is disposed on the outer wall of the rotating shaft 61, and the rack 64 is disposed on the connecting frame 5 and meshes with the gear 63.
[0031] When a cleanroom is in operation, it operates in the following two states:
[0032] First state: When it is necessary to enter the cleanroom 1 from the cloakroom 2 for work, the reducer 62 controls the rotating shaft 61 and gear 63 to rotate. At this time, the gear 63 drives the rack 64 and the connecting frame 5 to move synchronously. The connecting frame 5 drives the inner switch door 3 and the outer switch door 4 to move synchronously, so that the outer switch door 4 moves to the outside of the outer corridor 21 and is located in the cloakroom 2. At the same time, the inner switch door 3 abuts against the retaining ring 7 between the inner corridor 11 and the outer corridor 21. At this time, the staff in the cloakroom 2 can enter the outer corridor 21 and the inner corridor 11.
[0033] Subsequently, staff members walk in the outer corridor 21 and the inner corridor 11, while the connecting frame 5 drives the inner switch door 3 and the outer switch door 4 to move in opposite directions synchronously. When the inner switch door 3 moves to the outside of the inner corridor 11 and is located in the cleanroom 1, the outer switch door 4 simultaneously abuts against the retaining ring 7 between the inner corridor 11 and the outer corridor 21, at which point staff members can enter the cleanroom 1 to work.
[0034] Subsequently, the connecting frame 5 drives the inner switch door 3 and the outer switch door 4 to move in opposite directions synchronously again. When the inner switch door 3 blocks the inner corridor 11, the outer switch door 4 is located in the middle of the outer corridor 21. At this time, the inner corridor 11 and the outer corridor 21 are blocked, so that the cleanroom 1 is in a sealed state.
[0035] The second state: When it is necessary to enter the cloakroom 2 from the cleanroom 1, the reducer 62 controls the rotation of the shaft 61 and the gear 63. At this time, the gear 63 drives the rack 64 and the connecting frame 5 to move synchronously. The connecting frame 5 drives the inner door 3 and the outer door 4 to move synchronously, so that the inner door 3 moves to the outside of the inner corridor 11 and is located in the cleanroom 1. At the same time, the outer door 4 abuts against the retaining ring 7 between the inner corridor 11 and the outer corridor 21. At this time, the staff of the cleanroom 1 can enter the outer corridor 21 and the inner corridor 11.
[0036] Then, staff walk in the outer corridor 21 and the inner corridor 11, while using the connecting frame 5 to drive the inner switch door 3 and the outer switch door 4 to move in opposite directions synchronously. When the outer switch door 4 moves to the outside of the outer corridor 21 and is located in the cloakroom 2, the inner switch door 3 simultaneously abuts against the retaining ring 7 between the inner corridor 11 and the outer corridor 21, at which point staff can enter the cloakroom 2.
[0037] Subsequently, the connecting frame 5 drives the inner switch door 3 and the outer switch door 4 to move in opposite directions synchronously again. When the outer switch door 4 blocks the outer corridor 21, the inner switch door 3 is located in the middle of the inner corridor 11. At this time, the inner corridor 11 and the outer corridor 21 are blocked, so that the cleanroom 1 is in a sealed state.
[0038] Therefore, by setting up the dual cooperation of the inner switch door 3 and the outer switch door 4, the cloakroom 2 is closed when the cleanroom 1 is opened, and the cleanroom 1 is closed when the cloakroom 2 is open, so as to prevent dust in the cloakroom 2 from directly entering the cleanroom 1 and ensure the stability of the cleanroom 1's working process.
[0039] like Figure 4 As shown, a platform 8 is horizontally provided on the side of the inner switch door 3 and the outer switch door 4 that are close to each other. The lower end of the platform 8 is rotatably connected to the inner switch door 3 or the outer switch door 4. A pressure block 9 for pressing the platform 8 is rotatably connected to both the inner switch door 3 and the outer switch door 4.
[0040] like Figure 4 As shown, both sides of the platform 8 are rotatably connected to a pull rod 81, and a slider 82 is rotatably connected to the pull rod 81. The inner switch door 3 and the outer switch door 4 are both vertically provided with a sliding groove 83 for the slider 82 to slide.
[0041] When items need to be stored, control the rotation of the pressure block 9 to disengage it from the platform 8. Then, control the platform 8 to flip. At this time, the platform 8 drives the pull rod 81 to move synchronously. The pull rod 81 drives the slider 82 to slide within the slide groove 83 until the platform 8 flips to a horizontal position. The slider 82 is located at the bottom of the slide groove 83. At this time, the pull rod 81 tightens the platform 8, thus fixing it in place. Items can then be placed inside the platform 8 for storage. When the platform 8 is not in use, control the platform 8 to flip upwards, and then rotate the pressure block 9 to press the platform 8 firmly, thus fixing it in place.
[0042] Therefore, by setting up a platform 8 inside the inner door 3 and the outer door 4, workers can place items on the platform 8 when needed. When picking up and using items, workers do not need to go to the cloakroom 2 in the inner corridor 11 and the outer corridor 21, thus avoiding bringing dust into the cleanroom 1 and ensuring the stability of the cleanroom 1's working process.
[0043] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
