Description

Technical Field

[0001] This utility model relates to the field of airtight door technology, specifically an airtight front door protection device that enhances sealing performance. Background Technology

[0002] Airtight doors are sliding door sets that integrate airtightness, sound insulation, heat preservation, pressure resistance, dust prevention, fire prevention, and radiation protection. They are generally used in hospitals, food factories, industrial plants, and other places with high requirements for sound insulation, heat insulation, and airtightness.

[0003] Because airtight doors are sliding doors, prolonged back-and-forth sliding can cause friction between the door and the wall, resulting in damage to the back of the door. This allows outside air to enter the room through the damaged area, compromising airtightness and affecting indoor operations. Utility Model Content

[0004] The purpose of this invention is to provide an airtight front door protection device that enhances sealing performance, in order to solve the problem mentioned in the background art that prolonged back-and-forth sliding causes friction between the airtight door and the wall, resulting in damage to the rear side of the airtight door, allowing outside air to enter the room through the damaged area, thus causing poor airtightness.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an airtight front door protection device with enhanced sealing performance, comprising a wall, an inlet and outlet in the middle of the wall, a fixed plate fixedly connected to the upper surface of the wall, a guide rail on the inner side of the fixed plate, a movable wheel rotatably connected to the inner side of the guide rail, an airtight door fixedly connected to the lower surface of the movable wheel, a connecting groove on the inner side of the fixed plate near the guide rail, a connecting plate slidably connected to the inner side of the connecting groove, a push rod fixedly connected to one end of the connecting plate, a piston fixedly connected to one end of the push rod, an air pipe slidably connected to the outer surfaces of the push rod and the piston, a connecting tube fixedly connected to one outer surface of the air pipe, a sealing strip fixedly inserted into one end of the connecting tube, and an adhesive groove adhered to the outer surface of the sealing strip.

[0006] Preferably, a magnetic strip is fixedly connected to one outer surface of the first airtight door, a magnetic plate is slidably connected to the outer surface of the magnetic strip, and a second airtight door is fixedly connected to the outer surface of the magnetic plate.

[0007] Preferably, the connecting groove is an "L" shaped groove, the connecting plate is an "L" shaped plate, one end of the connecting plate is fixedly connected to the moving wheel, and the other end of the connecting plate is fixedly connected to the lower surface of the push rod. Its function is to drive the moving wheel to roll on the inside of the guide rail as the airtight door slides, thereby driving the connecting plate to slide synchronously on the inside of the connecting groove.

[0008] Preferably, the push rod is rod-shaped, the piston is frustum-shaped, and the air pipe is cylindrical. Two sets of cylindrical grooves are provided on the inner side of the air pipe. The push rod and piston are in two sets, and the push rod and piston are slidably connected to the inner side of the grooves. Their function is that as the first airtight door and the second airtight door approach each other, the moving wheels fixedly connected to the upper ends of the first airtight door and the second airtight door drive the connecting plate to slide in the direction of the air pipe on the inner side of the connecting groove, thereby driving the push rod and piston to advance in the direction of the connecting pipe on the inner side of the air pipe, thereby pushing the gas in the air pipe into the inner side of the connecting pipe.

[0009] Preferably, the connecting pipe is in the shape of a bent pipe. One end of the connecting pipe is fixedly connected to the outer surface of the trachea, and the other end of the connecting pipe is fixedly connected to the sealing strip. Its function is to allow air from the trachea to be introduced into the inner side of the sealing strip through the connecting pipe, thereby causing the sealing strip to expand and press against the first and second airtight doors. This prevents the first and second airtight doors from rubbing against the wall and causing wear on their rear sides. At the same time, it also makes the sealing strip contact the first and second airtight doors more tightly, thereby enhancing the sealing performance.

[0010] Preferably, the sealing strip is elongated and partially elastic, with a hollow inner side. The adhesive groove is a rectangular recess, with glue applied to the inner side. The sealing strip is adhered to the inner side of the adhesive groove by the glue, which serves to fix the sealing strip to the adhesive groove, thereby facilitating the replacement of the sealing strip later.

[0011] Preferably, the magnetic strip is elongated and the magnetic plate is L-shaped. The magnetic strip and the magnetic plate are slidably connected. The magnetic strip and the magnetic plate are magnetic. Their function is that when airtight door one and airtight door two are closed, the magnetic strip and the magnetic plate are slidably connected. With the magnetic attraction between the magnetic strip and the magnetic plate, the sealing of the connection between airtight door one and airtight door two is enhanced, preventing gas from entering the room from the connection between airtight door one and airtight door two.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By creating adhesive grooves on both sides of the outer surface of the wall near the inlet and outlet, the back side of the sealing strip is adhered to the inner side of the adhesive groove. When airtight doors one and two slide to close in the direction they are close to each other, the moving wheel rolls on the inner side of the guide rail, thereby driving the connecting plate to slide synchronously on the inner side of the connecting groove. This, in turn, drives the push rod and piston to slide on the inner side of the air pipe. By squeezing the inner side of the air pipe, the gas inside the air pipe enters the inner side of the sealing strip through the connecting pipe, thus bulging the sealing strip. This causes the sealing strip to squeeze airtight doors one and two, preventing friction between airtight doors one and two and the wall, thus preventing wear on the back side of airtight doors one and two. At the same time, it also makes the sealing strip contact airtight doors one and two more tightly, thereby enhancing the sealing performance.

[0014] 2. When airtight door one and airtight door two are closed, the magnetic strip and the magnetic plate slide together, and the magnetic attraction between the magnetic strip and the magnetic plate enhances the sealing of the connection between airtight door one and airtight door two, preventing gas from entering the room from the connection between airtight door one and airtight door two.

[0025] Furthermore, the connecting groove 10 is an "L" shaped groove, and the connecting plate 11 is an "L" shaped plate. One end of the connecting plate 11 is fixedly connected to the moving wheel 5, and the other end of the connecting plate 11 is fixedly connected to the lower surface of the push rod 12. Its function is to drive the moving wheel 5 to roll on the inside of the guide rail 4 as the airtight door 6 slides, thereby driving the connecting plate 11 to slide synchronously on the inside of the connecting groove 10.

[0026] Furthermore, the push rod 12 is rod-shaped, the piston 13 is frustum-shaped, and the air pipe 14 is cylindrical.

The push rod 12 and piston 13 are slidably connected to the inner side of the grooves. Their function is that as the airtight door 1 6 and the airtight door 2 9 approach each other, the moving wheel 5 fixedly connected to the upper end of the airtight door 1 6 and the airtight door 2 9 drives the connecting plate 11 to slide in the direction of the air pipe 14 on the inner side of the connecting groove 10, thereby driving the push rod 12 and piston 13 to advance in the direction of the connecting pipe 15 on the inner side of the air pipe 14, thereby pushing the gas in the air pipe 14 into the inner side of the connecting pipe 15.

[0027] Furthermore, the connecting pipe 15 is in the shape of a bent pipe. One end of the connecting pipe 15 is fixedly connected to the outer surface of the air pipe 14, and the other end of the connecting pipe 15 is fixedly connected to the sealing strip 16. Its function is to allow air in the air pipe 14 to be introduced into the inner side of the sealing strip 16 through the connecting pipe 15, thereby causing the sealing strip 16 to expand and press the airtight door 6 and the airtight door 9, thereby preventing the airtight door 6 and the airtight door 9 from rubbing against the wall 1 and causing wear on the back side of the airtight door 6 and the airtight door 9. At the same time, it also makes the sealing strip 16 contact the airtight door 6 and the airtight door 9 more tightly, thereby enhancing the sealing performance.

[0028] Furthermore, the sealing strip 16 is elongated and partially elastic, with a hollow inner side. The adhesive groove 17 is a rectangular groove with glue applied to its inner side. The sealing strip 16 is glued to the inner side of the adhesive groove 17, which serves to fix the sealing strip 16 to the adhesive groove 17, thus facilitating the replacement of the sealing strip 16 later.

[0029] Furthermore, the magnetic strip 7 is elongated and the magnetic plate 8 is L-shaped. The magnetic strip 7 and the magnetic plate 8 are slidably connected. The magnetic strip 7 and the magnetic plate 8 are magnetic. Their function is that when the airtight door 6 and the airtight door 9 are closed, the magnetic strip 7 and the magnetic plate 8 are slidably connected. With the magnetic attraction between the magnetic strip 7 and the magnetic plate 8, the sealing of the connection between the airtight door 6 and the airtight door 9 is enhanced, preventing gas from entering the room from the connection between the airtight door 6 and the airtight door 9.

[0030] Working principle: An inlet / outlet 2 is provided in the middle of wall 1. A fixed plate 3 is fixedly connected to the upper surface of wall 1. A guide rail 4 is provided on the inner side of the fixed plate 3. A movable wheel 5 is rolled on the inner side of the guide rail 4. An airtight door 6 is fixedly connected to the lower surface of the movable wheel 5. A connecting groove 10 is provided on the inner side of the fixed plate 3 near the guide rail 4. A connecting plate 11 is slidably connected to the inner side of the connecting groove 10. A push rod 12 is fixedly connected to one end of the connecting plate 11.

The back side of the sealing strip 16 is adhered to the inner side of the groove 17. When the airtight door 16 and the airtight door 29 slide to close in the direction of approaching each other, the moving wheel 5 will roll inside the guide rail 4, thereby driving the connecting plate 11 to slide synchronously inside the connecting groove 10, thereby driving the push rod 12 and the piston 13 to slide inside the air pipe 14. By squeezing the inner side of the air pipe 14, the gas inside the air pipe 14 enters the inner side of the sealing strip 16 through the connecting pipe 15, thereby bulging the sealing strip 16 and squeezing the airtight door 16 and the airtight door 29, thereby preventing the airtight door 16 and the airtight door 29 from rubbing against the wall 1 and causing wear on the back side of the airtight door 16 and the airtight door 29. At the same time, it also makes the sealing strip 16 contact the airtight door 16 and the airtight door 29 more tightly, thereby enhancing the sealing performance.
