Description

Technical Field

[0001] This utility model belongs to the field of flood control technology, and specifically relates to an isolation device with an adjustable hinge. Background Technology

[0002] In existing technologies, waterproof doors, as a common protective structure, are widely used in ships, underground engineering, water conservancy projects, and other scenarios requiring water penetration prevention. A waterproof door typically consists of a door body (i.e., a partition) and a hinge assembly, which connects the door body to the door frame to enable opening and closing. To ensure the sealing performance of the waterproof door, a sealing strip is usually installed between the door body and the door frame. When the door is closed, the sealing strip is compressed, thus forming an effective seal. However, in actual use, existing waterproof door hinge designs have certain defects. Traditional waterproof door hinges typically use a fixed or non-adjustable structure. While this structure is simple and easy to manufacture, it is prone to causing a series of problems during door opening. Specifically, when the door begins to open, the hinge rotates with the door's movement, causing one side of the door to shift relative to the other. Because the side of the door body in contact with the sealing strip experiences relative movement during opening, this change in movement trajectory can cause friction or even scratching between the door edge and the sealing strip. This scratching can damage the surface of the sealing strip, and in severe cases, may even lead to the sealing strip being rolled, deformed, or broken. Once the sealing strip is damaged, its original sealing performance will be greatly reduced, thus affecting the overall sealing effect of the waterproof door. More seriously, when the sealing strip curls or jams due to uneven force or excessive friction, the door may not be able to open smoothly. This will not only affect the normal operation of the equipment, but may also cause safety accidents, especially in situations where the sealing requirements are extremely high, such as submarine hatches, underground drainage systems, or water conservancy facilities.

[0003] Furthermore, traditional hinge structures lack adjustability, making it difficult to fine-tune them according to different installation environments or usage conditions. This results in an unsatisfactory door movement trajectory during opening, further exacerbating interference between the door and the sealing strip. Therefore, improving the hinge structure to ensure normal door opening while effectively preventing scratches between the door and the sealing strip, thereby enhancing the overall sealing performance and security of waterproof doors, has become a key technical challenge that urgently needs to be addressed by those skilled in the art. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide an isolation device with an adjustable hinge. By adopting a hinge structure with adjustable range, the technical problem in the prior art that the hinge rotation causes scratches between the partition and the sealing strip, damages the sealing strip, or even hinders the smooth opening of the partition is solved.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: An isolation device with an adjustable hinge includes: a three-sided sealing strip, an isolation plate, a connecting plate, and a hinge support frame. The lower end face of the isolation plate is provided with a hinge fixing member, and the hinge support frame is provided with a hinge. The upper end of the hinge is provided with a first connecting hole. A third hinge connecting member passes through the first connecting hole to fix the connecting plate to the isolation plate. The hinge fixing member is provided with a first hinge connecting hole and a second hinge connecting hole. The first hinge connecting member and the second hinge connecting member pass through the first hinge connecting hole and the second hinge connecting hole respectively to fix the connecting plate to the isolation plate. The first hinge connecting hole and the second hinge connecting hole are oblong holes. The length of the first hinge connecting hole is greater than the diameter of the first hinge connecting member, and the length of the second hinge connecting hole is greater than the diameter of the second hinge connecting member.

[0006] Compared to existing technologies, the advantages of this invention are as follows: By providing a first hinge connection hole and a second hinge connection hole with an oblong shape, this application solves the problem in existing technologies where hinge rotation during partition opening causes scratching or rolling of the sealing strip. Specifically, the oblong hole design allows the first and second hinge connectors to slide along their length within the hole, thereby dynamically adjusting the connection position during partition opening and compensating for displacement deviations caused by hinge rotation. This adjustability effectively avoids direct friction between the partition edge and the sealing strip, significantly reducing the risk of surface damage to the sealing strip, while also improving the smoothness of partition opening. Furthermore, the size design of the oblong hole (length greater than the diameter of the connector) ensures flexibility in the adjustment range, adapting to fine-tuning needs in different installation environments, further enhancing the adaptability and reliability of the device. This structural improvement not only extends the service life of the sealing strip but also reduces safety hazards caused by decreased sealing performance, such as water leakage or partition jamming due to seal failure.

[0007] The aforementioned isolation device has an oblong hole that extends vertically from the first hinge connection hole to the second hinge connection hole, and its length direction is perpendicular to the horizontal axis of the isolation plate in the stored state.

[0008] In the aforementioned isolation device, when the isolation plate is opened to 90°, the length direction of the vertically extending waist-shaped hole is parallel to the ground.

[0009] The aforementioned isolation device has an oblong hole that extends at an inclined direction from the first hinge connection hole to the second hinge connection hole, and the angle of inclination of its length direction to the horizontal axis of the isolation plate in the stored state is less than 90°.

[0010] In the aforementioned isolation device, the first connecting hole is an obliquely extending waist-shaped hole, and the oblique direction of the first connecting hole is opposite to the direction of the first hinge connecting hole and the second hinge connecting hole.

[0011] In the aforementioned isolation device, when the isolation plate is opened to 90°, the first hinge connection hole, the second hinge connection hole, and the first connection hole have the same tilt direction.

[0012] The aforementioned isolation device further includes a second connecting hole and a third connecting hole on the hinge. The second connecting hole and the third connecting hole are located at the lower end of the hinge and are on the same horizontal line.

[0013] The aforementioned isolation device further includes a hinge fixing plate on the hinge fixing component, with the first hinge connection hole and the second hinge connection hole located on the hinge fixing plate.

Detailed Implementation

[0019] The embodiments of this utility model are described in detail below, with reference to Figures 1 to 4This utility model provides an isolation device with an adjustable hinge, including: a three-sided sealing strip, an isolation plate 400, a connecting plate 200, and a hinge support frame 100. The lower end face of the isolation plate 400 is provided with a hinge fixing member 300. The hinge support frame 100 is provided with a hinge 110. The upper end of the hinge 110 is provided with a first connecting hole 111. A third hinge connector 800 passes through the first connecting hole 111 to fix the connecting plate 200 to the isolation plate 400. The hinge fixing member 300 is provided with a third hinge connector 800. A hinge connection hole 311 and a second hinge connection hole 312 are provided. A first hinge connector 600 and a second hinge connector 700 pass through the first hinge connection hole 311 and the second hinge connection hole 312, respectively, to fix the connecting plate 200 and the partition plate 400. The first hinge connection hole 311 and the second hinge connection hole 312 are oblong holes. The length of the first hinge connection hole 311 is greater than the diameter of the first hinge connector 600, and the length of the second hinge connection hole 312 is greater than the diameter of the second hinge connector 700. This application solves the problem in the prior art where hinge rotation during partition opening causes scratching or rolling of the sealing strip by providing the first hinge connection hole 311 and the second hinge connection hole 312 with oblong holes. Specifically, the oblong hole design allows the first hinge connector 600 and the second hinge connector 700 to slide along the length direction within the hole, thereby dynamically adjusting the connection position during partition opening and compensating for the displacement deviation caused by hinge rotation. This adjustability effectively avoids direct friction between the partition edge and the sealing strip, significantly reducing the risk of surface damage to the sealing strip while improving the smoothness of partition opening. Furthermore, the dimensional design of the oblong hole (length greater than the connector diameter) ensures flexibility in the adjustment range, adapting to fine-tuning needs in different installation environments and further enhancing the device's adaptability and reliability. This structural improvement not only extends the service life of the sealing strip but also reduces safety hazards caused by decreased sealing performance, such as water leakage or partition jamming due to seal failure.

[0020] Furthermore, referring to Figure 1 and Figure 2The first hinge connection hole 311 and the second hinge connection hole 312 are vertically extending oblong holes, with their length direction perpendicular to the horizontal axis of the partition plate 400 in the retracted state. In this case, when the partition plate 400 is opened to 90°, the length direction of the vertically extending oblong holes is parallel to the ground. Designing the first hinge connection hole 311 and the second hinge connection hole 312 as vertically extending oblong holes, with their length direction perpendicular to the horizontal axis of the partition plate 400 in the retracted state, further optimizes the movement trajectory of the partition when it is opened. The vertically extending oblong holes can guide the connector to slide in the vertical direction, thereby counteracting the lateral displacement caused by the hinge rotation during the partition's rotation, and reducing the contact area and friction between the edge of the partition and the sealing strip. This design is particularly suitable for scenarios where the partition needs to be opened and closed frequently. By limiting the sliding direction of the connector, this technical solution effectively avoids the problem of local stress concentration in the sealing strip caused by disordered displacement in traditional hinge structures, thereby significantly reducing the wear rate and probability of breakage of the sealing strip. Meanwhile, the vertical adjustment capability enhances the device's tolerance to installation errors. Even with slight manufacturing or assembly deviations, the oblong hole adjustment function allows for precise alignment of the partition and sealing strip, further improving the overall system's stability and sealing performance. When the partition is opened from 400° to 90°, the length of the vertically extending oblong hole is parallel to the ground, resolving the issue of hinge displacement causing seal damage at extreme opening angles. When the partition is fully open, the length of the oblong hole changes from vertical to horizontal, allowing the connector to slide horizontally, thus compensating for lateral hinge displacement when the partition rotates to its limit. This design avoids the "dragging" effect of the partition edge on the sealing strip during opening, especially in scenarios where the partition needs to be fully extended (such as emergency drainage or rapid isolation), significantly reducing the risk of the sealing strip being rolled or broken due to severe friction.

[0021] Furthermore, referring to Figure 3 and Figure 4The first hinge connection hole 311 and the second hinge connection hole 312 are obliquely extending waist-shaped holes, with their length direction tilted at an angle of less than 90° to the horizontal axis of the partition plate 400 in the retracted state. Simultaneously, the first connection hole 111 is also an obliquely extending waist-shaped hole, with its tilt direction opposite to that of the first hinge connection hole 311 and the second hinge connection hole 312. In this configuration, when the partition plate 400 is opened to 90°, the tilt directions of the first hinge connection hole 311, the second hinge connection hole 312, and the first connection hole 111 are the same. Designing the first hinge connection hole 311 and the second hinge connection hole 312 as obliquely extending waist-shaped holes, with their tilt direction tilted at an angle of less than 90° to the horizontal axis of the partition plate 400, solves the problem of matching the movement trajectory of the partition plate with the sealing strip in complex installation environments. The obliquely extending waist-shaped holes allow the connectors to slide at a specific angle, thereby accommodating the asymmetric displacement of the partition plate during opening due to space constraints or structural limitations. For example, in confined spaces or scenarios requiring avoidance of other equipment, the rotation axis of the partition may not be perfectly horizontal. In such cases, the inclined oblong hole can dynamically compensate for the partition's deflection angle by adjusting the position of the connector, preventing damage to the sealing strip due to abnormal contact. Furthermore, the adjustable tilt direction enhances the device's compatibility with different installation angles. For instance, in applications with inclined walls or non-horizontal floors, the precise fit between the partition and the sealing strip can be achieved by adjusting the tilt angle of the oblong hole, thereby improving sealing performance and operational reliability. By specifying that the first connecting hole 111 extends in an oblong direction, and that its tilt direction is opposite to that of the first hinge connecting hole 311 and the second hinge connecting hole 312, the problem of uneven stress on multi-stage hinge connectors is solved. When the partition opens, the reverse tilt design of the first connecting hole 111 balances the displacement directions of the upper and lower ends of the hinge, thereby reducing the overall torsional load on the hinge. This symmetrical adjustment mechanism effectively disperses the stress distribution of the connector during the opening process, reducing the risk of fatigue fracture of the hinge components due to localized overload. Furthermore, the reverse-tilted oblong holes optimize the movement trajectory of the partition, ensuring a smoother rotation during opening and reducing partition wobbling or jamming caused by uneven hinge force. When the partition 400 is opened to 90°, the tilt directions of the first hinge connection hole 311, the second hinge connection hole 312, and the first connection hole 111 are the same, solving the problem of insufficient coordination of multi-stage hinge connectors at extreme angles. When the partition is fully open, all oblong holes with the same tilt direction can synchronously guide the connectors to slide in the same direction, thereby ensuring consistent displacement of all parts of the hinge.

[0022] Furthermore, the hinge 110 is also provided with a second connecting hole 112 and a third connecting hole 113, which are located at the lower end of the hinge 110 and are on the same horizontal line. By providing the second connecting hole 112 and the third connecting hole 113 on the hinge 110 and specifying that they are on the same horizontal line, the problem of unstable connection at the lower end of the hinge is solved. The horizontally arranged connecting holes can evenly distribute the force on the lower end of the hinge, avoiding hinge deflection or connector detachment caused by overload of one side of the connector. This design is particularly suitable for applications where the partition is heavy or needs to withstand dynamic impact (such as floodgates or industrial equipment isolation devices). Through the horizontally symmetrical connection structure, the overall rigidity and deformation resistance of the hinge are enhanced. Furthermore, the hinge fixing member 300 is also provided with a hinge fixing plate 310, on which the first hinge connecting hole 311 and the second hinge connecting hole 312 are located. By setting a hinge fixing plate 310 on the hinge fixing member 300, and placing the first hinge connection hole 311 and the second hinge connection hole 312 on this fixing plate, the problem of easy displacement of the hinge fixing position is solved. As an independent support structure, the hinge fixing plate 310 can precisely guide the sliding direction of the connecting member through its oblong hole, thereby reducing the displacement deviation of the hinge due to vibration or load changes during long-term use. This design not only enhances the connection stability between the hinge and the isolation plate, but also improves the adaptability of the device to complex working conditions.

[0023] Furthermore, the three-way seal 500 includes a vertical seal and a horizontal seal, which are integrally formed. The three-way seal 500, comprising both vertical and horizontal seals, and being an integrally formed structure, further enhances the sealing performance and structural stability of the device. The synergistic effect of the vertical and horizontal seals covers all potential leakage paths between the partition and the door frame. For example, when the partition is closed, the vertical seal is responsible for sealing the top and bottom, while the horizontal seal is responsible for sealing the sides, thus forming a comprehensive sealing barrier. The integrally formed structure also ensures that the seals maintain a uniform stress distribution during long-term compression or tension, avoiding material fracture or performance degradation caused by localized stress concentration.
