Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Referring to fig. 1, fig. 2 and fig. 3, the sliding door structure of the present invention comprises a sliding door 10, a connecting block 11, a rodless cylinder slider 12, a rodless cylinder body 13, an air sealing seat 14, an air sealing ring 15, a locking block 16, a guide rail mounting seat 17, a fixing block 18, a linear bearing 19, and a guide rod 20. The linear bearing 19 of the present embodiment is a wear-resistant sliding bearing.

The rodless cylinder sliding block 12 and the sliding door 10 are connected through the connecting block 11, the rodless cylinder sliding block 12 can move along the rodless cylinder body 13, the inflatable sealing ring 15 is clamped in the groove of the air sealing seat 14, the linear bearing 19 is connected with the sliding door 10 through the fixing block 18, and the linear bearing 19 is sleeved on the guide rod 20 and can move along the guide rod 20.

The sliding door 10 includes a door panel mounting seat 101, a gasket 102, a door panel 103, and a door panel pressing block 104. The sealing pad 102 and the door plate 103 are pressed in the groove of the door plate mounting seat 101 by the door plate pressing block 104, and the rodless cylinder slider 12 is connected with the door plate mounting seat 101 of the sliding door 10 by a connecting block 11. The door plate 103 of this embodiment is made of a transparent material (e.g., a glass plate, an acrylic plate, a transparent resin plate, etc.).

In addition, the rodless cylinder body 13 is connected to a compressed air source (not shown) through an air pipe disposed in the hollow guide rod 20, and when the rodless cylinder body 13 is inflated, the rodless cylinder slider 12 is driven to move, and the door panel mounting seat 101 is driven to move along the guide rod 20.

In addition, the sliding door structure of the present embodiment is further provided with a position sensor (not shown), and when the position sensor detects that the door panel mounting seat 101 has moved to a predetermined position, the position sensor sends a command signal for inflating the inflatable gasket 15, so that the inflatable gasket 15 is inflated. The inflatable gasket 15 inflated by air fills the gap between the air sealing seat 14 and the door panel mounting seat 101, thereby sealing the door panel 103.

With the sliding door structure of the present embodiment, the following technical effects can be obtained.

1. Because the rodless cylinder is adopted to replace the traditional rod cylinder, lubricating agents such as lubricating oil are not used for lubricating the cylinder, and therefore pollution to a clean space connected through the sliding door structure of the embodiment caused by the lubricating agents such as the lubricating oil can be prevented.

2. Since the linear bearing employs the wear-resistant sliding bearing, it is possible to further prevent contamination of a clean space connected through the sliding door structure of the embodiment due to the use of a lubricant such as lubricating oil, compared to the prior art of a linear bearing or a sliding groove sliding structure requiring lubrication using a lubricant such as lubricating oil.

3. Due to the arrangement of the position sensor, the door plate reaching the closing position can be sealed with high precision.

4. Compared with the prior art, the utility model discloses a door structure of sliding is succinct compacter, consequently can reduce the sterilization dead angle.

In addition, as the sliding door structure of the other embodiment, the following modifications are possible, and a general linear bearing may be adopted as the linear bearing, so that at least the technical effects 1, 3, and 4 described above can be obtained. The rodless cylinder body 13 may be connected to a compressed air source directly through an air pipe disposed outside the guide rod 20. Further, the position sensor may not be provided, and thus at least the technical effects 1, 2, and 4 described above can be obtained.

In addition, in the above embodiment, the fixing block 18 may be omitted, that is, the linear bearing 19 and the sliding door 10 are directly connected. Thus, the technical effects 1 to 4 described above can be obtained.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
