Description

Technical Field

[0001] The utility model relates to the technical field of archive preservation, in particular to an intelligent micro-archive room sealing structure. Background Art

[0002] Important data such as archives need to be preserved for a long time. Therefore, it is necessary to maintain a suitable environment for their storage space to avoid damage to important data caused by the external environment.

[0003] At present, there are two ways to store important information, one is archives, and the other is archives room. Archives belong to the architectural archival storage space. It uses temperature and humidity adjustment and ventilation equipment to build the rooms of the building into different archives rooms. The construction cost is extremely high and the mobility is poor. It is only suitable for users who need to store a large number of archives. It is usually impossible to transform ordinary buildings into archives rooms. It needs to be rebuilt as a whole, and the construction period is long. The intelligent micro archive room is a small cabinet. By installing temperature and humidity adjustment and ventilation equipment on the cabinet to change the storage environment inside the cabinet, the life of the archives stored in the cabinet is guaranteed. It is not only small in size, but also can be equipped with mobile wheels for easy transportation. In addition, it can be placed directly in existing ordinary buildings. Therefore, it is suitable for users who have a small amount of archive storage needs and no need to build archives. Not only is the cost low, but also the appropriate number of cabinets can be appropriately selected according to later needs to achieve expansion, and the structure is more flexible. Although the above two methods can meet the needs of file storage in different situations, the sealing structure of the existing file cabinets is poor. For example, patent CN11188188A discloses a sealed moisture-proof file cabinet, which is provided with a plurality of placement slots on the cabinet body, and a cabinet door is rotatably installed on each placement slot, and an isolation strip is fixedly attached to the edge of the cabinet door, and a circle of second filling cavities are sequentially opened in the isolation strip, and a first filling cavity is provided on one side of each second filling cavity, and the first filling cavity is opened in the isolation strip, and a semi-permeable membrane is provided between the second cavity and the isolation strip, a suction cup is provided below the first filling cavity, and a breathable membrane is provided above the first filling cavity, and the first filling cavity and the second filling cavity are filled with salt solutions of the same concentration, by arranging an isolation strip on the edge of the cabinet door, and the isolation strip can be effectively adsorbed on the cabinet body according to the humidity, and at the same time, the salt solution in the first filling cavity changes from a water absorption state to a water loss state in an environment with high air humidity, so that the suction cup is squeezed and adsorbed on the cabinet body to achieve sealing. Although it can meet the sealing requirements, its sealing effect is completely dependent on the changes in the first filling cavity of the isolation strip to achieve compression. In the later stage, it is very easy to accidentally touch the cabinet door and cause the sealing failure. In addition, when the cabinet door is closed, if the isolation strip in the initial state is not tight, it will directly lead to the problem of sealing failure, which will also affect the archive preservation effect.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the attached Figure 1 To Attachment Figure 2 The technical solution provided by the utility model is described in detail, but the following content is not intended to limit the utility model.

[0024] Figure 1 A structural diagram showing a perspective of an embodiment of a sealing structure of an intelligent micro-archive room of the utility model; Figure 2 This is a structural diagram from another perspective of an embodiment of the intelligent micro-archive room sealing structure of the utility model. Figure 1 and Figure 2 As shown, the sealing structure of the intelligent micro-archive room provided in this embodiment includes: a cabinet body 1, a cabinet door 2, and a sealing strip 3 and a tensioning lock 4 arranged between the cabinet body 1 and the cabinet door 2. The sealing strip 3 is used to achieve the sealing between the cabinet body 1 and the cabinet door 2, and the cabinet door 2 is tightened to the cabinet body 1 by the tensioning lock 4, which provides a pre-tightening force for the sealing between the cabinet door 2 and the cabinet body 1, thereby improving the reliability and effectiveness of the sealing, effectively avoiding the problem of sealing failure, and facilitating the long-term preservation of archives.

[0025] Specifically, a first sealing surface 111 is provided on the side edge of the door frame 11 and located on the outer surface of the door frame 11, that is, the first sealing surface 111 is arranged on the side of the door frame 11 that will contact the cabinet door 2 later. At the same time, a second sealing surface 21 corresponding to the first sealing surface 111 is provided on the side edge of the cabinet door 2 and located on the inner surface of the cabinet door 2, that is, the second sealing surface 21 is arranged on the side of the cabinet door 2 that will contact the door frame 11 later, and the first sealing surface 111 and the second sealing surface 21 correspond to each other. In addition, the sealing strip 3 is provided on the first sealing surface 111 or the second sealing surface 21, that is, the sealing strip 3 is arranged within the range of the sealing surface between the cabinet door 2 and the door frame 11, and can be fixed relative to the cabinet door 2 or the door frame 11, to ensure the stability and reliability of the sealing strip 3 during sealing. When the cabinet door 2 is subsequently closed toward the cabinet body 1 and fully closed, the first sealing surface 111 on the door frame 11 and the second sealing surface 21 on the cabinet door 2 are directly opposite to each other, so that the first sealing surface 111 and the second sealing surface 21 can form a relative structure, which provides conditions for the subsequent compression of the sealing strip 3 to achieve sealing. At this time, the two sides of the sealing strip 3 located between the first sealing surface 111 and the second sealing surface 21 are respectively in close contact with the first sealing surface 111 and the second sealing surface 21, and the gap between the first sealing surface 111 and the second sealing surface 21 is filled by the sealing strip 3 to meet the use requirement of sealing the gap between the cabinet door 2 and the cabinet body 1.

[0026] Specifically, the tension lock 4 includes a first locking portion 41 and a second locking portion 42. During installation, the first locking portion 41 is arranged on the door frame 11 and is located on the side edge of the door frame 11, and the second locking portion 42 is arranged on the cabinet door 2 and is located on the side edge of the inner surface of the cabinet door 2, that is, when the cabinet door 2 is closed toward the cabinet body 1, the second locking portion 42 can move with the cabinet door 2 toward the first locking portion 41, and the second locking portion 42 corresponds to the first locking portion 41 to provide a pre-tightening force for sealing when the cabinet door 2 and the cabinet body 1 are subsequently tightened. At this time, the tension lock 4 is located on the outer side of the first sealing surface 111 and the second sealing surface 21, that is, on the cabinet door 2 and the cabinet body 1, the sealing parts are located on the side close to the space inside the cabinet, and the tension lock 4 is located on the side away from the space inside the cabinet, so that the sealing of the space inside the cabinet will not be affected by the installation of the tension lock 4, that is, the first locking part 41 and the second locking part 42 of the tension lock 4 need to be opened during installation, and the influence of the opening for the installation of the tension lock 4 on the sealing can be avoided, ensuring the effectiveness and reliability of the sealing. At this time, when the cabinet door 2 is closed toward one side of the cabinet body 1 and is closed in place, the first locking part 41 and the second locking part 42 can face each other, realizing the locking and unlocking of the first locking part 41 and the second locking part 42. Furthermore, after the first locking portion 41 and the second locking portion 42 are locked, the distance between the first locking portion 41 and the second locking portion 42 is smaller than the thickness of the sealing strip 3 in the initial state, so that when the cabinet door 2 and the cabinet body 1 are locked by the tensioning lock 4, the tensioning lock 4 can provide a pre-tightening force for the locking of the cabinet door 2 and the cabinet body 1, thereby compressing the sealing strip 3 between the first sealing surface 111 and the second sealing surface 21, so that the sealing strip 3 can be tightly attached to the first sealing surface 111 and the second sealing surface 21, thereby improving the sealing effect. In addition, it can also prevent the cabinet door 2 and the cabinet body 1 from separating in an accidental situation, thereby causing the sealing to fail, thereby further ensuring the effectiveness and reliability of the sealing.

[0027] More specifically, the first locking part 41 of the tension lock 4 is a lock body, and the second locking part 42 is a lock pin that cooperates with the lock mouth of the lock body. At this time, a lock tongue is provided in the lock mouth of the lock body. When the first locking part 41 and the second locking part 42 are locked with each other, the lock pin is inserted into the lock mouth and restricted by the lock tongue, thereby realizing the locking of the tension lock 4. When the first locking part 41 and the second locking part 42 are unlocked, the lock tongue releases the restriction on the lock pin, and the lock pin is removed from the lock mouth, thereby meeting the use requirements of locking and unlocking the first locking part 41 and the second locking part 42. It is worth pointing out that the lock body and the lock pin can be commonly used locks on the market. In this embodiment, a suitable type of lock can be selected according to actual installation requirements. Therefore, its specific structure is not repeated here.

[0028] More specifically, the first locking portion 41 is arranged on the cross beam and / or the bottom beam of the door frame 11, and a lock hole 112 is opened on the side edge of the outer surface of the cross beam and / or the bottom beam provided with the first locking portion 41. Preferably, the first locking portion 41 is arranged on both the cross beam and the bottom beam of the door frame 11, so that the upper and lower ends of the cabinet door 2 are provided with the tension lock 4 to provide pre-tightening force, ensuring that both ends of the cabinet door 2 have stress points, further improving the sealing reliability. At this time, the lock body is installed on the cabinet 1 and the lock mouth of the lock body is directly opposite to the lock hole 112, so that when the cabinet door 2 is subsequently closed in place, the lock pin can pass through the lock hole 112 and cooperate with the lock mouth, which not only realizes the hidden installation of the lock body in the cabinet 1 and improves the aesthetics, but also provides design conditions for the distance between the first locking portion 41 and the second locking portion 42 after they are locked to be less than the thickness of the sealing strip 3 in the initial state, and the structural design is more reasonable.

[0029] More specifically, the first sealing surface 111 and the second sealing surface 21 are both arranged in an annular frame shape, so that the door frame 11 and the cabinet door 2 have corresponding first sealing surfaces 111 and second sealing surfaces 21 in one circle, achieving all-round sealing and higher sealing reliability. At this time, the sealing strip 3 is also arranged in an annular frame structure, so that the sealing strip 3 can seal the door frame 11 of the cabinet 1 and the cabinet door 2 around, and the sealing effect is better.

[0030] More specifically, a protruding door liner 22 is provided on the inner surface of the cabinet door 2 and in the area surrounded by the sealing strip 3. The door liner 22 expands the inner space of the cabinet door 2, which not only increases the structural strength of the cabinet door 2, but also provides conditions for filling fireproof materials in the cabinet door 2. In addition, the door liner 22 is arranged to protrude toward one side of the cabinet body 1, so that when the cabinet door 2 is closed in place, the door liner 22 can be embedded in the position where the internal space of the cabinet body 1 is located, realizing space utilization and more reasonable space layout.

[0031] More specifically, an anti-extrusion structure 5 is also provided on the door frame 11, and in this case, the anti-extrusion structure 5 includes a fixing plate 51 and a push rod 52. The fixing plate 51 is fixedly mounted on the cabinet body 1, and at the same time, one end of the push rod 52 is fixedly mounted on the fixing plate 51, so that the push rod 52 is stably mounted on the cabinet body 1. In addition, the other end of the push rod 52 is extended toward one side of the cabinet door 2, so that when the cabinet door 2 is closed, the inner surface of the cabinet door 2 can contact the extended end of the push rod 52 when the cabinet door 2 is fully closed, thereby limiting the continued closing of the cabinet door 2, preventing the cabinet door 2 from being over-closed and causing the sealing strip 3 and the lock body and other structures to be pressed, and having better safety protection.

[0032] More specifically, a accommodating cavity is provided at the top and / or bottom of the cabinet 1. At this time, the lock hole 112 corresponding to the lock port of the lock body is connected to the accommodating cavity. At this time, the first locking part 41 is installed in the accommodating cavity, that is, the lock body is installed in the accommodating cavity, thereby realizing a hidden installation of the first locking part 41 and making more reasonable use of space.

[0033] More specifically, each accommodating cavity has an installation cavity opening, which facilitates the installation and subsequent inspection and maintenance of the first locking portion 41 and other structures in the accommodating cavity. In addition, an inspection cover 6 is provided in the installation cavity opening of the accommodating cavity, and the installation cavity opening of the accommodating cavity is opened or closed by the inspection cover 6, thereby achieving external protection and facilitating subsequent inspection and maintenance.

[0034] More specifically, hinge blocks 7 are provided at the top and bottom of the door frame 11 of the cabinet 1. At this time, one end of the hinge block 7 is fixed on the door frame 11, and at the same time, the other end of the hinge block 7 is extended toward one side of the cabinet door 2. The installation area of ​​the upper and lower ends of the door frame 11 of the cabinet 1 is expanded by the hinge block 7, so that the upper and lower ends of the door frame 11 of the cabinet 1 have extended installation carriers. In addition, a rotating shaft is provided at the top and bottom of one side of the cabinet door 2, and the two rotating shafts are rotatably installed on one end extended by the two hinge blocks 7, that is, the installation carrier extended by the hinge block 7 provides installation conditions for the two rotating shafts of the cabinet door 2, so that the cabinet door 2 can be installed completely independently of the cabinet 1, avoiding the problem that the sealing of the outer surface of the door frame 11 of the cabinet 1 is destroyed due to the provision of hinges and other structures on the outer surface of the door frame 11 of the cabinet 1, and at the same time, it also provides an avoidance space for the deflection of the cabinet door 2, and the structural design is more reasonable. In addition, the distance between the axis of the rotating shaft and the first sealing surface 111 is set to be smaller than the sum of the thickness of the sealing strip 3 in the initial state and the distance from the axis of the rotating shaft to the second sealing surface 21, so that when the cabinet door 2 is closed, the side of the cabinet door 2 hinged on the cabinet body 1 can also provide a pre-tightening force through the hinge block 7, so that the sealing strip 3 is compressed, ensuring the effectiveness and reliability of the sealing of the sealing strip 3 between the first sealing surface 111 and the second sealing surface 21. It can be used in conjunction with the tensioning lock 4 to achieve tensioning of the top and bottom of both sides of the cabinet door 2, so that the cabinet door 2 is subjected to more uniform force, further improving the reliability and effectiveness of the sealing.

[0035] Figure 3 This is a structural diagram of a sealing strip of a preferred embodiment of the utility model; Figure 4 This is a cross-sectional view of the sealing strip and the pressure strip when they are installed in a preferred embodiment of the utility model. Figures 1 to 4As shown, the sealing strip 3 includes a backing adhesive layer 31, a main sealing strip 32 and a pressure strip 37. At this time, a circle of backing adhesive layer 31 is arranged on the first sealing surface 111 or the second sealing surface 21 and on the opposite side of the two. Preferably, the backing adhesive layer 31 is arranged on the outer edge of the second sealing surface 21. At this time, the main sealing strip 32 is also arranged in a circle, and the main sealing strip 32 is a ring-shaped structure consistent with the shape of the backing adhesive layer 31, so that the backing adhesive layer 31 and the sealing strip 3 can surround the cabinet door 2 and the door frame 11 when the cabinet door 2 is closed, thereby ensuring that the cabinet door 2 can seal the cavity of the storage cavity of the cabinet body 1 when the cabinet door 2 is closed, thereby ensuring the sealing performance. In addition, one side of the main sealing strip 32 is set as a bonding surface 331, and the main sealing strip 32 is bonded to the backing adhesive layer 31 through the bonding surface 331, that is, the main sealing strip 32 is installed on the first sealing surface 111 or the second sealing surface 21 through the backing adhesive layer 31. At the same time, the other side of the main sealing strip 32 is set as the sealing contact surface 351, and when the cabinet door 2 is closed, the sealing contact surface 351 can be tightly attached to the door frame 11 or the cabinet door 2, that is, when the back adhesive layer 31 is set on the cabinet door 2, then when the cabinet door 2 is subsequently closed, the sealing contact surface 351 of the main sealing strip 32 can be tightly attached to the door frame 11 to meet the sealing requirements. In addition, a pressing edge 33 is provided along the length direction of the side of the main sealing strip 32 where the adhesive surface 331 is provided. The pressing edge 33 expands the contact area of ​​the side of the main sealing strip 32 where the adhesive surface 331 is provided. At the same time, a pressure strip 37 is arranged along the length direction of the main sealing strip 32 on the side of the pressure strip 33 away from the adhesive layer 31. At this time, the pressure strip 37 is fixedly connected to the second sealing surface 21 or the first sealing surface 111, that is, when the adhesive layer 31 is provided on one of the cabinet door 2 and the door frame 11, the pressure strip 37 is also provided thereon, thereby realizing a unified arrangement of the main sealing strip 32 and the pressure strip 37, and ensuring that the pressure strip 37 can stably press the main sealing strip 32. In addition, after the pressure strip 37 is installed in place, the pressure strip 37 is directly and stably installed on the cabinet door 2 or the door frame 11, so that the pressure strip 37 can press the bonding surface 331 onto the adhesive layer 31 while also pressing the adhesive layer 31 onto the cabinet door 2 or the door frame 11, thereby achieving the purpose of stably fixing the pressure strip 37 and the main sealing strip 32 on the cabinet door 2 or the door frame 11, so that the installation of the main sealing strip 32 can be bonded by the adhesive layer 31 and pressed by the pressure strip 37, thereby achieving multiple fixation of the main sealing strip 32, thereby ensuring the installation reliability of the main sealing strip 32, and effectively avoiding the problem of the main sealing strip 32 becoming loose during subsequent use and affecting the sealing of the smart micro-archive room.

[0036] As a preferred embodiment, a receiving cavity 34 arranged along the length direction of the main sealing strip 32 is provided on the side close to the adhesive layer 31, that is, the receiving cavity 34 is provided inside the main sealing strip 32, and an installation space is formed inside the main sealing strip 32 through the receiving cavity 34.

[0038] As a preferred embodiment, a through hole connecting to the accommodating cavity 34 is opened on the main sealing strip 32. At this time, the through hole passes through the pressing edge 33, so that when the second connecting hole on the pressure strip 37 is connected with the first connecting hole on the cabinet door 2 or the door frame 11, the screws used to connect the first connecting hole and the second connecting hole can enter into the accommodating cavity 34 from the through hole, and the installation is more convenient. That is, when the first connecting hole and the second connecting hole are connected by screws, the screws pass through the through hole at the same time, which facilitates the installation and disassembly of the pressure strip 37, thereby facilitating the installation of the main sealing strip 32 and the replacement after later damage.

[0039] As a further preferred embodiment, the lengths of the two side walls of the cross section of the accommodating cavity 34 are set to be different, so that the thicknesses of the two side walls of the sealing main strip 32 are different. At this time, the side wall with a shorter length in the cross section of the accommodating cavity 34 is a side wall close to the center of the cabinet door 2 or the door frame 11, so that the sealing main strip 32 can be tilted toward the inner side of the storage cavity of the cabinet body 1 after installation, so that when the cabinet door 2 is closed, the outer side of the sealing main strip 32 is deformed more greatly and the sealing effect is better.

[0040] As a further preferred embodiment, the pressure strip 37 is a sheet metal pressure strip 37, that is, the pressure strip 37 is a long plate-shaped metal structure, which not only has high structural strength and is not easy to deform, but also can provide a sufficiently large contact area, further ensuring the clamping effect.

[0041] As a further preferred embodiment, an inflation cavity 35 is further provided in the sealing main strip 32. At this time, the inflation cavity 35 is provided on the side of the sealing main strip 32 away from the adhesive layer 31, that is, one side of the sealing surface of the sealing main strip 32 has the inflation cavity 35. At this time, the outer surface of the side wall of the inflation cavity 35 away from the adhesive layer 31 is the sealing contact surface 351, so that the part of the sealing main strip 32 bearing the sealing contact surface 351 is the inflation cavity 35. Through the inflation cavity 35, the deformation performance of the side of the sealing main strip 32 with the sealing contact surface 351 is better, which is easy to deform under pressure during sealing, providing a larger sealing contact surface 351 area, thereby improving the sealing effect. In addition, it can also reduce the overall weight and save materials.

[0042] As a further preferred embodiment, the cross section of the air-filled cavity 35 is arranged in a rectangular shape, so that the side walls of the main sealing strip 32 constituting the air-filled cavity 35 are all planes, that is, the sealing contact surface 351 of the main sealing strip 32 is a plane, which provides conditions for the subsequent sealing contact surface 351 to be closely attached to the door frame 11 or the cabinet door 2. In addition, magnetic powder is embedded in the side wall of the air-filled cavity 35 on the side away from the adhesive layer 31, and the side wall of the main sealing strip 32 having the sealing contact surface 351 is magnetic, so that when the main sealing strip 32 is closely attached to the door frame 11 or the cabinet door 2, the main sealing strip 32 can be naturally magnetically attracted to the door frame 11 or the cabinet door 2, which can meet the use requirements of the cabinet door 2 being able to automatically close when the cabinet door 2 and the cabinet body 1 are in a relatively small opening and closing state, and at the same time, it can also prevent the problem of the cabinet door 2 accidentally opening after closing, thereby ensuring the sealing effect.

[0043] As a further preferred embodiment, the main sealing strip 32 also has a rapid deformation portion 36. At this time, the rapid deformation portion 36 is arranged between the edge pressing 33 and the inflation cavity 35 as a deformation structure between the bonding surface 331 and the sealing contact surface 351. At this time, the rapid deformation portion 36 also includes two connecting walls 361. When manufacturing the main sealing strip 32, the two ends of the two connecting walls 361 of the rapid deformation portion 36 are respectively connected to the side walls of the edge pressing 33 and the inflation cavity 35, so that the deformation performance of the main sealing strip 32 is better, which provides conditions for subsequent compression deformation and close contact with the door frame 11 or the cabinet door 2. In addition, the connecting walls 361 of the rapid deformation portion 36 are arranged in multiple sections, so that the deformation margin is larger, the deformation capacity is stronger, and the adaptability is better. Preferably, at least one section of each connecting wall 361 is an arc structure, which can not only avoid the problem of fatigue damage caused by stress concentration, but also ensure the smoothness of the outer surface during the deformation process, improve the aesthetics while ensuring the deformation capacity, and facilitate the cleaning in the later stage.

Part 42, and the tensioning lock 4 is located on the outer side of the first sealing surface 111 and the second sealing surface 21. A sealing structure can be formed by the sealing strip 3, the first sealing surface 111 and the second sealing surface 21 to achieve sealing between the cabinet door 2 and the cabinet body 1, and the tensioning lock 4 is arranged on the outer side of the formed sealing structure to avoid the influence of the installation and use of the tensioning lock 4 on the formed sealing structure, and the cabinet door 2 and the cabinet body 1 are tightened by the tensioning lock 4, which provides a pre-tightening force for the sealing structure, ensures the reliability and effectiveness of the sealing, and meets the long-term preservation requirements of archives.
