Description

Technical Field

[0001] This utility model relates to the field of sealing device technology, and in particular to a fireproof sealing device for a pass-through window pressing door. Background Technology

[0002] In experimental environments with high airtightness requirements, such as biosafety laboratories, clean laboratories, or specific chemical laboratories, pass-through windows serve as crucial channels for transferring materials, and their airtightness is paramount. To ensure that the pass-through window effectively isolates the inside from the outside air when closed, a sealing gasket is typically installed between the pass-through window and the pressure door to provide the necessary airtightness. However, existing sealing gasket materials still have certain defects in high-temperature or fire-resistant environments, affecting their sealing performance.

[0003] Currently, common gaskets are mainly made of ordinary rubber materials, but these materials are prone to softening and deformation under high temperatures or open flame environments, leading to a decrease in sealing performance. To address this issue, some gaskets are made of composite materials incorporating fire-retardant materials to improve their high-temperature and fire-resistant properties. However, these gaskets often harden entirely under high temperatures, losing their original elasticity and thus affecting the sealing effect. Therefore, existing gaskets still suffer from insufficient airtightness in terms of high-temperature and fire-resistant performance. Utility Model Content

[0004] This utility model addresses the problems and shortcomings of existing technologies by providing a fireproof sealing device for a pass-through window pressing door.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] This utility model provides a fireproof sealing device for a pass-through window pressing door. The pass-through window includes a pass-through window box with a front pass-through window and a rear pass-through window, a front pressing door and a rear pressing door.

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] like Figure 1-2 As shown, this embodiment provides a fireproof sealing device for a pass-through window pressing door. The pass-through window includes a pass-through window box 1 with a front pass-through window and a rear pass-through window, a front pressing door 2 and a rear pressing door 3. The fireproof sealing device includes a front sealing groove 4 along the inner wall of the front pass-through window, a rear sealing groove along the inner wall of the rear pass-through window, a front fireproof sealing gasket 5 matching the shape of the front sealing groove 4, and a rear fireproof sealing gasket 6 matching the shape of the rear sealing groove.

[0015] The front fireproof sealing gasket 5 and the rear fireproof sealing gasket 6 have the same structure, both including an m-shaped soft sealing gasket body 51 with an m-shaped cross-section and a rectangular soft sealing gasket body 52 with a rectangular cross-section. The bottom of the m-shaped soft sealing gasket body 51 is fixed to the top of the rectangular soft sealing gasket body 52. ​​Both the m-shaped soft sealing gasket body 51 and the rectangular soft sealing gasket body 52 are rubber sealing gaskets, and the m-shaped soft sealing gasket body 51 and the rectangular soft sealing gasket body 52 are integrally formed.

[0016] The rectangular soft sealing gasket 52 has a rigid fireproof inner core 53 inside. The shape of the rigid fireproof inner core 53 matches the internal contour of the rectangular soft sealing gasket 52. The rigid waterproof inner core 53 is a graphite rigid fireproof inner core.

[0017] like Figure 3 As shown, the front fireproof sealing gasket 5 is embedded in the front sealing groove 4 to seal the front pressure door 2 and the transfer window box 1. The contact point between the front fireproof sealing gasket 5 and the front sealing groove 4 is bonded together with sealant. The m-shaped soft sealing gasket body 51 of the front fireproof sealing gasket 5 is attached to the front pressure door 2, and the rectangular soft sealing gasket body 52 of the front fireproof sealing gasket 5 is attached to the bottom of the front sealing groove 4.

[0018] The installation method of the rear fireproof sealing gasket 6 is exactly the same as that of the front fireproof sealing gasket 5. The rear fireproof sealing gasket 6 is embedded in the rear sealing groove to seal the rear pressure door 3 and the transfer window box 1. The contact point between the rear fireproof sealing gasket 6 and the rear sealing groove is bonded with sealant. The m-shaped soft sealing gasket body 51 of the rear fireproof sealing gasket 6 is attached to the rear pressure door 3, and the rectangular soft sealing gasket body 52 of the rear fireproof sealing gasket 6 is attached to the bottom of the rear sealing groove.

[0019] like Figure 4As shown, both the front fireproof sealing gasket 5 and the rear fireproof sealing gasket 6 are square, with rounded corners at each end. Both the front fireproof sealing gasket 5 and the rear fireproof sealing gasket 6 are composed of multiple segments joined together.

Then, the rear fireproof sealing gasket 6 is embedded in the rear sealing groove, sealing the rear pressing door 3 and the pass-through window housing 1. When the front pressing door 2 and the rear pressing door 3 are pressed tightly against the front and rear pass-through windows respectively, the front fireproof sealing gasket 5 and the rear fireproof sealing gasket 6 are deformed under pressure, effectively improving the sealing performance. The rigid fireproof inner core 53 embedded in the rectangular soft sealing gasket body 52 provides effective support, preventing the front fireproof sealing gasket 5 and the rear fireproof sealing gasket 6 from deforming and failing in high-temperature or open-flame environments, thus ensuring that it has both good sealing performance and fireproof and high-temperature resistance.

[0021] This invention provides a fireproof sealing device for a pass-through window's pressure door. The device includes a front fireproof sealing gasket and a rear fireproof sealing gasket, both comprising an M-shaped soft sealing gasket body and a rectangular soft sealing gasket body. The outer layers of the front and rear fireproof sealing gaskets are soft and elastic, and are respectively installed within the front and rear sealing grooves of the pass-through window. After the front and rear pressure doors are pressed together, the front and rear fireproof sealing gaskets deform and fit together under pressure, effectively improving sealing performance. A rigid fireproof inner core is inserted within the rectangular soft sealing gasket body, providing necessary support and preventing deformation and failure of the front and rear fireproof sealing gaskets under high temperature or open flame conditions. This invention combines excellent airtightness, fire resistance, and stability, making it suitable for laboratories with high airtightness requirements.
