Description

Technical Field

[0001] This utility model relates to the field of sealing mechanism technology, and in particular to a stainless steel manifold sealing mechanism. Background Technology

[0002] In industrial production, medical protection, and emergency rescue scenarios, face shields are crucial equipment for protecting users' respiratory systems from harmful gases, dust, and microorganisms. The sealing performance of the connection between the face shield and the filter element directly determines the protective effect. Currently, most mainstream face shields on the market use threaded connections, snap-fit ​​connections, or rubber gasket compression methods to connect with the filter element.

[0003] Threaded connections are cumbersome to use when frequently changing filter elements, requiring tools or considerable effort to install and remove, especially in emergencies where they cannot meet the need for quick replacements. Furthermore, prolonged use can lead to thread wear and stripping, resulting in decreased sealing performance, leakage risks, and threats to user safety.

[0004] The snap-fit ​​connection structure is limited by the snap-fit's elastic deformation capacity, and its sealing reliability highly depends on the snap-fit's machining precision and assembly quality. In complex environments, such as under conditions of vibration, high temperature, or low temperature, the snap-fit ​​is prone to loosening, leading to gaps between the filter element and the mask, allowing harmful media to enter. Furthermore, the connection points between the snap-fit ​​and the mask / filter element are mostly made of plastic, which is prone to losing elasticity due to aging after prolonged use, further exacerbating the sealing failure problem.

[0005] The sealing effect of a gasket-compression connection structure is greatly affected by the material properties and compression of the gasket. With increased use, the gasket ages and hardens, losing elasticity and becoming unable to maintain a stable compression, thus leading to a decline in sealing performance. Furthermore, this structure requires ensuring uniform force on the gasket during installation; otherwise, localized incomplete seals can easily occur, increasing operational difficulty and the risk of leakage. Therefore, this invention proposes a stainless steel manifold sealing mechanism. Utility Model Content

A second rotating plate is fixedly connected to the third rotating shaft, and a fourth rotating shaft is fixedly connected to the end of the second rotating plate away from the third rotating shaft. The fourth rotating shaft is slidably engaged with the upper bracket.

[0012] Optionally, the two sets of first rotating plates and the two sets of second rotating plates are arranged in a one-to-one correspondence and cross-shaped arrangement, and the cross-shaped positions are rotatably connected to a positioning shaft.

[0013] Optionally, the locking mechanism includes an adjusting plate fixedly connected to both ends of the first rotating shaft. The adjusting plate is fan-shaped and has an arc-shaped groove. The third rotating shaft is slidably connected to the arc-shaped groove.

[0014] Optionally, a synchronization plate is fixedly connected between the two sets of adjustment plates. A clamping plate is fixedly connected to the side of the synchronization plate near the filter element. One end of the clamping plate is clamped to the side of the clamping block. A pressure block is installed on the side of the clamping plate near the filter element.

[0015] Optionally, it also includes a fixing mechanism for positioning multiple sets of connecting pipes. The fixing mechanism includes two sets of symmetrically arranged positioning frames.

[0018] This utility model, through the linkage design of the locking mechanism's synchronization plate, adjustment plate, and support components, allows the lower bracket to move closer to or away from the upper bracket simply by manually rotating the synchronization plate. Combined with the sliding engagement between the filter element's T-shaped mounting plate and the lower bracket's mounting groove, it enables quick installation and removal of the filter element. The entire process requires no tools, which can significantly shorten replacement time, especially in emergency situations, and solves the problem of cumbersome operation of traditional threaded connections, snap-fit ​​connections, and other structures.

[0019] Furthermore, the smooth movement of the lower support achieves tight contact between the connecting pipe and the connecting cylinder. The locking mechanism's locking plate and locking block engage, the pressure block positions the filter element, and the fixing mechanism's pressure plate presses the connecting pipe positioning ring and the limiting block limits the pressure plate. This forms a multi-mechanical limiting structure that can maintain stable sealing pressure under complex environments such as vibration and temperature changes. It avoids sealing failure problems caused by thread wear, loose buckles, and aging of rubber gaskets in traditional structures, effectively eliminating the risk of leakage.

[0020] In summary, this invention enables quick filter replacement without tools and eliminates the risk of leakage, ensuring user safety and improving operational efficiency. Attached Figure Description

[0038] Example

[0039] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, this utility model proposes a stainless steel manifold sealing mechanism, including a side plate 1. An upper bracket 2 is fixedly connected to one side of the side plate 1, and the position of the upper bracket 2 is fixed after the side plate 1 is installed and fixed. A lower bracket 3 is provided below the upper bracket 2, and both the upper bracket 2 and the lower bracket 3 are U-shaped. A filter element 4 is installed in the lower bracket 3, and an installation groove 31 is opened in the lower bracket 3. An installation plate 41 is fixedly connected to the top of the filter element 4. The installation plate 41 is T-shaped and is slidably connected to the installation groove 31, which facilitates the sliding installation of the filter element 4 into the lower bracket 3. A locking block 42 is fixedly connected to the side of the installation plate 41 away from the upper bracket 2. Multiple sets of connecting cylinders 43 that penetrate the installation plate 41 are connected to the filter element 4. Multiple sets of connecting pipes 5 are connected to the upper bracket 2, and the connecting pipes 5 achieve quick connection after being connected to the connecting cylinders 43. The bottom of the connecting tube 5 is stepped. The connecting tube 5 passes through the upper bracket 2. The upper bracket 2 has multiple through holes, which allows multiple connecting tubes 5 to be placed in different positions when adapting to different models of filter elements 4. A sealing cap 51 is installed on the connecting tube 5, and a positioning ring 52 is fixedly connected to the outer ring of the connecting tube 5. The positioning ring 52 is located above the upper bracket 2.

[0040] For further details, please refer to Figures 1 to 3The aforementioned sealing mechanism includes a support assembly 6 disposed between the upper support 2 and the lower support 3. The support assembly 6 connects the lower support 3 and the upper support 2 while ensuring the smooth movement of the lower support 3. The support assembly 6 includes a first rotating shaft 61 rotatably connected to the end of the upper support 2 away from the side plate 1, and the first rotating shaft 61 rotates while remaining in its original position. Two sets of first rotating plates 62 are rotatably connected to the first rotating shaft 61, and the first rotating plates 62 are rotatably connected to the upper support 2 through the first rotating shaft 61. A second rotating shaft 63 is fixedly connected to the end of the first rotating plate 62 away from the first rotating shaft 61, and the second rotating shaft 63 is slidably engaged with the lower support 3. When the first rotating plate 62 deflects, it drives the second rotating shaft 63 to slide within the lower support 3. The support assembly 6 also includes two sets of third rotating shafts 64 rotatably connected to the end of the lower support 3 away from the side plate 1. A second rotating plate 65 is fixedly connected to the third rotating shaft 64, and the second rotating plate 65 is rotatably connected to the lower support 3 through the third rotating shaft 64. A fourth rotating shaft 66 is fixedly connected to the end of the second rotating plate 65 away from the third rotating shaft 64. The fourth rotating shaft 66 is slidably engaged with the upper bracket 2. When the second rotating plate 65 deflects, it drives the fourth rotating shaft 66 to slide within the upper bracket 2. Two sets of first rotating plates 62 correspond one-to-one with two sets of second rotating plates 65 and are arranged crosswise. A positioning shaft 67 is rotatably connected at the crosswise position. Through the arrangement of the first rotating plates 62 and second rotating plates 65, when the lower bracket 3 moves relative to the upper bracket 2, the first rotating plates 62 and second rotating plates 65 deflect synchronously, so that the lower bracket 3 moves smoothly.

[0041] Specifically, the sealing mechanism includes a locking mechanism 7 installed at the end of the upper bracket 2 away from the side plate 1. The locking mechanism 7 is used to cooperate with the support assembly 6 to move the lower bracket 3. The locking mechanism 7 includes adjusting plates 71 fixedly connected to both ends of the first rotating shaft 61. The adjusting plates 71 are fan-shaped. An arc-shaped groove 72 is provided on the adjusting plate 71. The third rotating shaft 64 is slidably connected in the arc-shaped groove 72. When the adjusting plate 71 rotates, it drives the third rotating shaft 64 to move through the guiding action of the arc-shaped groove 72, thereby moving the lower bracket 3. A synchronization plate 73 is fixedly connected between the two sets of adjusting plates 71, and the synchronization plate 73 drives the two sets of adjusting plates 71 to rotate synchronously. A clamping plate 74 is fixedly connected to the side of the synchronization plate 73 near the filter element 4. One end of the clamping plate 74 is engaged with the side of the clamping block 42. After rotating the synchronization plate 73, the adjusting plate 71 is rotated, which in turn causes the lower bracket 3 to move closer to the upper bracket 2. The clamping plate 74 then engages with the clamping block 42, limiting the synchronization plate 73 and ensuring that the lower bracket 3 is close to the upper bracket 2. This allows the connecting cylinder 43 to make tight contact with the bottom of the connecting pipe 5, achieving a sealed connection. A pressure block 75 is installed on the side of the clamping plate 74 near the filter element 4. The pressure block 75 contacts the side of the filter element 4 to position the filter element 4.

[0042] Furthermore, such as Figure 1 , Figure 2 and Figure 5As shown, the sealing mechanism also includes a fixing mechanism 8 for positioning multiple sets of connecting pipes 5. The fixing mechanism 8 includes two sets of symmetrically arranged positioning frames 81. The positioning frames 81 are U-shaped and fixedly connected to the upper bracket 2. Multiple sets of support plates 82 are fixedly connected to opposite sides of the two sets of positioning frames 81. A pressure plate 83 is provided above the support plate 82. The positioning frames 81 limit the pressure plate 83, and the support plates 82 support the pressure plate 83. The connecting pipe 5 passes through the pressure plate 83, and the positioning ring 52 is located below the pressure plate 83. The pressure plate 83 presses on the positioning ring 52 to prevent the connecting pipe 5 from moving upward, thereby achieving a tight connection after the connecting cylinder 43 moves upward and contacts the connecting pipe 5. A limiting block 84 is slidably connected in the positioning frame 81. The limiting block 84 is trapezoidal in shape. During installation, the pressure plate 83 contacts the inclined surface of the limiting block 84, pressing the limiting block 84 to move it. Simultaneously, after the pressure plate 83 passes the position of the limiting block 84, the limiting block 84 limits the pressure plate 83, preventing it from moving upwards, and thus preventing the connecting pipe 5 from moving upwards. This ensures that after the filter element 4 moves upwards, the bottom of the connecting pipe 5 is inserted into the connecting cylinder 43, achieving a sealed connection. Multiple sets of sliding rods 85 are fixedly connected to the side of the limiting block 84 away from the pressure plate 83. A limiting bracket 86 is slidably connected to the sliding rods 85. The limiting bracket 86 is L-shaped and fixedly connected to the positioning frame 81. The fixed position of the limiting bracket 86, combined with the limiting effect of the sliding rods 85, ensures smooth movement of the limiting block 84. A spring 87 is fitted onto the slide rod 85. The spring 87 is located between the limiting block 84 and the limiting bracket 86. When the pressure plate 83 presses against the limiting block 84, the limiting block 84 moves and compresses the spring 87. The spring 87 accumulates elastic force. After the pressure plate 83 passes the position of the limiting block 84, the spring 87 releases its elastic force, causing the limiting block 84 to return to its original position. The ends of multiple slide rods 85 away from the limiting block 84 are fixedly connected to a moving plate 88. When the moving plate 88 is moved, the limiting block 84 is moved through the slide rods 85, making it easy to remove the pressure plate 83 after removing the limiting block 84 from above the pressure plate 83. This allows for the replacement of the pressure plate 83 corresponding to the position of the connecting tube 5 when the position of the connecting tube 5 needs to be changed for different models of filter elements 4.

[0043] In this embodiment, when installing the filter element 4, the T-shaped mounting plate 41 of the filter element 4 is slidably inserted into the mounting groove 31 of the lower bracket 3, so that the filter element 4 is precisely locked in the lower bracket 3. At this time, the connecting cylinder 43 at the top of the filter element 4 is initially aligned with the connecting pipe 5 of the upper bracket 2. During the installation process, the T-shaped structure of the mounting plate 41 and the cooperation with the mounting groove 31 restrict the shaking of the filter element 4, ensuring that the axis of the connecting cylinder 43 and the connecting pipe 5 are consistent, laying the foundation for subsequent sealing.

[0044] The synchronous plate 73 of the rotating locking mechanism 7 drives the two sets of fan-shaped adjusting plates 71 to rotate synchronously around the first rotating shaft 61. The arc-shaped groove 72 of the adjusting plate 71, through sliding engagement with the third rotating shaft 64, pushes the lower support 3 closer to the upper support 2. At the same time, the first rotating plate 62 and the second rotating plate 65 of the supporting assembly 6 cross-rotate around the positioning shaft 67. With the sliding and rotational engagement of the first rotating shaft 61, the second rotating shaft 63, the third rotating shaft 64, and the fourth rotating shaft 66, the lower support 3 is ensured to rise smoothly. When the bottom of the connecting pipe 5 is inserted into the connecting cylinder 43, the positioning ring 52 of the outer ring of the connecting pipe 5 is in contact with the upper pressure plate 83. The pressure plate 83 cannot move upward under the limiting action of the limiting block 84, thereby preventing the connecting pipe 5 from moving upward and ensuring that the connecting pipe 5 and the connecting cylinder 43 are in close contact. At this time, the locking plate 74 of the locking mechanism 7 is engaged with the side of the locking block 42 of the filter element 4 mounting plate 41, and the pressure block 75 is tightly attached to the side of the filter element 4. The position of the lower bracket 3 is fixed by mechanical limiting, ensuring stable sealing pressure at the connection and eliminating leakage gaps.

[0045] When replacing filter element 4, rotate the synchronization plate 73 in the reverse direction to disengage the clamping plate 74 from the clamping block 42. The adjusting plate 71 moves the lower bracket 3 downward through the arc groove 72, and the support assembly 6 unfolds accordingly, separating the connecting pipe 5 from the connecting cylinder 43. Then, slide the old filter element 4 out along the mounting groove 31, and insert the new filter element 4 into the lower bracket 3 according to the initial installation steps. Repeat the sealing connection process to complete the replacement.

[0046] When it is necessary to adapt to different models of filter element 4, the limiting block 84 is disengaged from the pressure plate 83 by the moving plate 88, so that the pressure plate 83 with the corresponding through hole can be replaced according to the filter element 4 model to adapt to different connecting cylinder 43 layouts.

[0047] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
