Description

Technical Field

[0001] This utility model relates to the technical field of cleanroom door and window sealing structure, specifically to a sealing connection structure between a cleanroom door panel and a cleanroom window. Background Technology

[0002] A cleanroom refers to a well-sealed space where parameters such as air cleanliness, temperature, humidity, pressure, and noise are controlled as needed. Publication number CN223202970U discloses a cleanroom door and a cleanroom itself. By setting up a first and second connecting structure, the door panel can rotate, thus opening and closing the door. However, during the use of the cleanroom door panel, a sealing strip is used to seal it. This sealing strip is easily affected by the impact of opening and closing the door, thus impacting the seal. Therefore, we propose a sealing connection structure between the cleanroom door panel and the cleanroom window. Utility Model Content

[0003] In view of the problems in the prior art, this utility model provides a sealing connection structure between the cleanroom door panel and the cleanroom window. The technical solution adopted by this utility model to solve its technical problem is a sealing connection structure between a cleanroom door panel and a cleanroom window, including a frame base, a stepped groove is provided on the inner circumference of the frame base, and a plate frame that fits into the stepped groove is hinged to the inner side of the frame base through a rotating shaft, and a rubber gasket that abuts against the plate frame is snapped into the inner side of the stepped groove. The stepped groove has a set of straight holes for storage. A T-shaped ball head block for buffering is slidably installed inside the straight hole. A retaining ring that is screwed into the straight hole and connected to the T-shaped ball head block is also installed inside the straight hole. A compression spring for buffering is assembled between the straight hole and the T-shaped ball head block.

[0004] By adopting the above technical solution, during the use of cleanroom doors and windows, the stepped groove and the frame can fit together to provide a certain sealing performance, and with the help of the rubber gasket, the frame can be more tightly connected to the frame base; the frame is hinged inside the frame base, which facilitates hinge swing and thus facilitates opening and closing; and the frame and frame base can be replaced and adjusted according to the specifications of the cleanroom doors or windows to adapt to both and facilitate the use of the cleanroom, thus providing good sealing for the cleanroom doors and windows; When opening and closing the doors or windows of the cleanroom, the retaining ring in the straight hole conveniently limits the T-shaped ball head block, allowing the T-shaped ball head block to slide stably in the straight hole, and the spherical end of the T-shaped ball head block can easily pass through the retaining ring and extend out of the straight hole; when the plate frame hinges and swings to close and engages with the frame seat, the spherical end of the T-shaped ball head block can first abut against the plate frame, and under the elastic support of the compression spring in the straight hole, it can buffer the closure of the plate frame, allowing it to return to its closed position more stably and seal the inside of the frame seat. Moreover, the structure in the straight hole can be disassembled and maintained simply by unscrewing the screwed retaining ring in the straight hole.

[0005] Specifically, the inner wall surface of the stepped groove is provided with a frame hole, and a frame strip is slidably installed inside the frame hole. The side of the plate frame near the stepped groove is provided with a V-shaped frame groove that matches the frame strip. The V-shaped frame groove and the opposite side of the frame strip are equipped with magnetic blocks that are magnetically connected to each other. There are multiple sets of magnetic blocks. The outer circumference of the frame strip is integrally constructed with a protrusion that matches the frame hole. The outer wall surface of the frame hole is equipped with a frame body that abuts against the protrusion by screws. There are two sets of frame bodies.

[0006] By adopting the above technical solution, when the plate frame returns to its original position and the hole inside the frame seat is sealed, the multiple sets of magnetic blocks in the V-shaped frame groove on the plate frame can be magnetically connected with the magnetic blocks on the frame strip. This allows the frame strip to drive the protrusion to slide along the inner wall of the frame hole under the magnetic attraction. The two sets of frame bodies on the frame hole can conveniently limit the frame strip. At the same time, the side of the frame strip extending out of the frame hole can easily fit with the V-shaped frame groove on the plate frame, which can conveniently seal the gap between the plate frame and the stepped groove, thereby improving the tightness of the closure between the two.

[0007] Specifically, the stepped groove and the opposite side of the plate frame are both provided with a mouth-shaped groove, and the stepped groove and the opposite side of the plate frame are both integrally constructed with a mouth-shaped strip that matches the mouth-shaped groove.

[0008] By adopting the above technical solution, the groove and strip between the stepped groove and the plate frame fit together, which facilitates the operation of the stepped groove and further improves the tightness of the connection between the plate frame and the stepped groove.

[0009] Specifically, both the inner wall surface of the orifice groove and the inner wall surface of the V-shaped frame groove are bonded with protective sponge pads.

[0010] By adopting the above technical solution, the sponge pad has good elasticity, which facilitates the improvement of the tightness of the connection between the mouth groove and the mouth strip, and the sponge pad in the V-shaped frame groove also facilitates the improvement of the tightness of its connection with the frame strip.

[0011] Specifically, the inner circumference of the retaining ring is provided with a hexagonal hole for rotation, and the outer circumference of the T-shaped ball head block is bonded with a protective rubber sleeve.

[0012] By adopting the above technical solution, the hexagonal hole on the inner circumference of the retaining ring makes it easier to disassemble and assemble, while the rubber sleeve has good elasticity, which helps to reduce the damage caused by the T-shaped ball head block colliding with the plate frame.

[0013] Specifically, a glass plate is fitted at the open end of the inner periphery of the frame.

[0014] By adopting the above technical solution, the glass plate can easily seal the openings inside the frame, while also facilitating personnel to observe the condition inside the clean room.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The technical solution of this application, through the design of the plate frame, stepped groove and rubber gasket, can provide a certain sealing performance by utilizing the step groove and plate frame to fit together during the use of cleanroom door panels and clean windows. With the assistance of the rubber gasket, the plate frame can be more tightly connected to the frame base. The plate frame is hinged and installed inside the frame base, which facilitates hinge swing and thus facilitates opening and closing. Furthermore, the plate frame and frame base can be replaced and adjusted according to the specifications of the cleanroom door panel or window to adapt to both and facilitate the use of the cleanroom, thereby providing good sealing performance for the cleanroom door and window.

[0016] 2. The technical solution of this application, through the design of a straight hole, a retaining ring, a T-shaped ball head block, and a compression spring, allows the retaining ring in the straight hole to limit the T-shaped ball head block when the door or window of the clean room is opened or closed. This enables the T-shaped ball head block to slide stably in the straight hole, and the spherical end of the T-shaped ball head block can easily pass through the retaining ring and extend out of the straight hole. When the plate frame is hinged and swings to close and engages with the frame seat, the spherical end of the T-shaped ball head block can first abut against the plate frame. Under the elastic support of the compression spring in the straight hole, it can buffer the closure of the plate frame, enabling it to return to its closed position more stably and seal the inside of the frame seat. Furthermore, the structure in the straight hole can be disassembled and maintained simply by unscrewing the retaining ring screwed into the straight hole.

[0017] 3. The technical solution of this application, through the design of frame holes, frame strips, V-shaped frame grooves, frame bodies, protrusions, and magnetic blocks, allows multiple sets of magnetic blocks in the V-shaped frame grooves on the frame to magnetically connect with the magnetic blocks on the frame strips when the plate frame returns to its original position and the holes inside the frame base are sealed. This facilitates the frame strips to drive the protrusions to slide along the inner wall of the frame holes under the magnetic attraction. The two sets of frame bodies on the frame holes facilitate the limiting of the frame strips. At the same time, the side of the frame strips extending out of the frame holes can easily fit with the V-shaped frame grooves on the plate frame, facilitating the sealing of the gap between the plate frame and the stepped groove, thereby improving the tightness of the closure between the two.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a sealing connection structure for a cleanroom door panel and a cleanroom window, including a frame base 1, a stepped groove 3 is provided on the inner circumference of the frame base 1, and a plate frame 2 that fits into the stepped groove 3 is hinged to the inner side of the frame base 1 via a pivot. A rubber pad 4 that abuts against the plate frame 2 is snapped into the inner side of the stepped groove 3. A straight hole 5 for receiving is provided on the inner side of the stepped groove 3, and there are multiple sets of straight holes 5. A T-shaped ball head block 7 for buffering is slidably installed on the inner side of the straight hole 5, and a retaining ring 6 that is screwed into and connected to the T-shaped ball head block 7 is screwed into the inner side of the straight hole 5. A compression spring 8 for buffering is assembled between the straight hole 5 and the T-shaped ball head block 7.

[0022] During use, the stepped groove 3 and the frame 2 fit together to provide a certain sealing performance. With the help of the rubber gasket 4, the frame 2 can be more tightly connected to the frame base 1. The frame 2 is hinged inside the frame base 1, which facilitates hinge swing and opening and closing. The frame 2 and the frame base 1 can be replaced and adjusted according to the specifications of the cleanroom door or window to adapt to both and facilitate the use of the cleanroom, thus providing good sealing for the cleanroom door and window. When the doors or windows of the cleanroom are opened and closed, the retaining ring 6 in the straight hole 5 can conveniently limit the T-shaped ball head block 7, so that the T-shaped ball head block 7 can slide stably in the straight hole 5 and the spherical end of the T-shaped ball head block 7 can easily pass through the retaining ring 6 and extend out of the straight hole 5. When the plate frame 2 is hinged and swings to close and is engaged with the frame base 1, the spherical end of the T-shaped ball head block 7 can first abut against the plate frame 2, and under the elastic support of the compression spring 8 in the straight hole 5, it can buffer the closing of the plate frame 2, so that it can return to its position and close more stably and seal the inside of the frame base 1. Moreover, the structure in the straight hole 5 can be disassembled and maintained simply by unscrewing the screwed retaining ring 6 in the straight hole 5.

[0023] like Figure 2 and Figure 4 As shown, a frame hole 9 is provided on the inner wall surface of the stepped groove 3, and a frame strip 10 is slidably installed inside the frame hole 9. A V-shaped frame groove 11 that fits with the frame strip 10 is provided on the side of the plate frame 2 near the stepped groove 3. Magnetic blocks 14 that are magnetically connected to each other are installed on the opposite side of the V-shaped frame groove 11 and the frame strip 10. There are multiple sets of magnetic blocks 14. The outer circumference of the frame strip 10 is integrally constructed with a protrusion 13 that fits with the frame hole 9. A frame body 12 that abuts against the protrusion 13 is installed on the outer wall surface of the frame hole 9 by screws. There are two sets of frame bodies 12.

[0024] When in use, when the plate frame 2 returns to its original position and seals the hole inside the frame base 1, the multiple sets of magnetic blocks 14 in the V-shaped frame groove 11 on the plate frame 2 can be magnetically connected with the magnetic blocks 14 on the frame strip 10. This allows the frame strip 10 to drive the protrusion 13 to slide along the inner wall of the frame hole 9 under magnetic attraction. The two sets of frame bodies 12 on the frame hole 9 can conveniently limit the frame strip 10. At the same time, the side of the frame strip 10 extending out of the frame hole 9 can easily fit with the V-shaped frame groove 11 on the plate frame 2, which can conveniently seal the gap between the plate frame 2 and the stepped groove 3, thereby improving the tightness of the two after closure.

[0025] like Figure 2 and Figure 4 As shown, the stepped groove 3 and the plate frame 2 are both provided with a mouth-shaped groove 16 on their opposite sides, and the stepped groove 3 and the plate frame 2 are both integrally constructed with a mouth-shaped strip 15 that matches the mouth-shaped groove 16.

[0026] When in use, the groove 16 and the strip 15 between the stepped groove 3 and the plate frame 2 fit together, which facilitates the operation of the stepped groove 3 and further improves the tightness of the plate frame 2 and the stepped groove 3 after they fit together.

[0027] like Figure 2 and Figure 4 As shown, both the inner wall surface of the orifice groove 16 and the inner wall surface of the V-shaped frame groove 11 are bonded with protective sponge pads 17.

[0028] When in use, the sponge pad 17 has good elasticity, which makes it easier to improve the tightness of the connection between the mouth groove 16 and the mouth strip 15, and the sponge pad 17 in the V-shaped frame groove 11 also makes it easier to improve the tightness of the connection between it and the frame strip 10.

[0029] like Figure 2 and Figure 3 As shown, the inner circumference of the retaining ring 6 is provided with a hexagonal hole 18 for rotation, and the outer circumference of the T-shaped ball head block 7 is bonded with a protective rubber sleeve 19.

[0030] When in use, the hexagonal hole 18 on the inner circumference of the retaining ring 6 makes it easier to disassemble and assemble the retaining ring 6, while the rubber sleeve 19 has good elasticity, which helps to reduce the damage caused by the T-shaped ball head block 7 and the plate frame 2 colliding with each other.

[0031] like Figure 1 and Figure 2 As shown, a glass plate 20 is fitted at the open end of the inner periphery of the frame 2.

[0032] When in use, the glass plate 20 can easily seal the opening inside the frame 2, while also allowing personnel to observe the condition inside the clean room.

[0033] Working principle and usage process of this utility model: In use, the corresponding structural components are first installed in the appropriate positions. During the use of cleanroom doors and windows, the stepped groove 3 and the frame 2 can fit together to provide a certain sealing performance. With the auxiliary sealing of the rubber gasket 4, the frame 2 can be more tightly connected to the frame base 1. The frame 2 is hinged inside the frame base 1, which facilitates hinged swinging and thus facilitates opening and closing. The frame 2 and frame base 1 can be replaced and adjusted according to the specifications of the cleanroom doors or windows to adapt to both and facilitate cleanroom use, thus providing good sealing for the cleanroom doors and windows. At the same time, when the cleanroom doors or windows are opened and closed, the retaining ring 6 in the straight hole 5 can limit the T-shaped ball head block 7, so that the T-shaped ball head block 7 can slide stably in the straight hole 5, and the spherical end of the T-shaped ball head block 7 can easily pass through the retaining ring 6 and extend out of the straight hole 5. When the frame 2 hinges and swings to close and fits with the frame base 1, the T-shaped ball head block... The spherical end of 7 facilitates initial contact with the plate frame 2 and, under the elastic support of the compression spring 8 in the straight hole 5, provides a buffer for the closing of the plate frame 2, enabling it to return to its closed position more stably and seal the interior of the frame base 1. Furthermore, the structure within the straight hole 5 can be disassembled and maintained simply by unscrewing the screw-on retaining ring 6. When the plate frame 2 returns to its original position and seals the hole inside the frame base 1, the multiple sets of magnetic blocks 14 in the V-shaped groove 11 on the plate frame 2 can interact with the magnetic strips on the frame bar 10. The suction blocks 14 are magnetically connected to each other, which allows the frame strip 10 to drive the protrusion 13 to slide along the inner wall of the frame hole 9 under the magnetic attraction. The two sets of frame bodies 12 on the frame hole 9 can limit the frame strip 10. At the same time, the side of the frame strip 10 that extends out of the frame hole 9 can fit into the V-shaped frame groove 11 on the plate frame 2, which can seal the gap between the plate frame 2 and the stepped groove 3, thereby improving the tightness after the two are closed, so that the clean room doors and windows can be used more stably.
