Description

Technical Field

[0001] This invention relates to the field of waterproofing technology, and more particularly to a sealed box with a waterproof structure. Background Technology

[0002] The information disclosed in this background section is intended only to enhance understanding of the overall background of the invention and is not necessarily to be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art.

[0003] Equipment installed in tunnels and sewer environments requires high waterproof performance and must be easy to assemble and disassemble on site. The sealed boxes of the equipment are usually installed on the tunnel walls and are subject to the test of dripping water and seepage. Therefore, the waterproof performance of the sealed boxes is very important.

[0004] On-site work often requires disassembling, repairing, or replacing parts of various devices inside sealed enclosures, as well as debugging programs. Some sealed enclosures are vertically mounted on walls, with sealing rings and covers installed on the vertical surface. When removing the cover, the sealing rings frequently fall off, causing difficulties in disassembly and reassembly. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a sealed box with a waterproof structure to solve the problem of the sealing ring easily falling off when disassembling the box lid.

[0006] To achieve the above objectives, the embodiments of the present invention provide the following technical solutions:

[0007] A waterproof sealed box includes: a box body, a sealing ring, a box cover, and a connector that connects the box body, the sealing ring, and the box cover in sequence; the connector has a threaded section and a smooth section, the threaded section is used for detachable connection with the box body, the sealing ring has a sealing ring through hole that mates with the smooth section, the diameter of the sealing ring through hole is smaller than the diameter of the smooth section, and the diameter of the smooth section is smaller than the diameter of the threaded section.

[0008] In another preferred embodiment of the present invention, the end face of the box cover facing the box body has a through hole protrusion, and the end face of the sealing ring facing the box cover is provided with a clearance groove, and the through hole protrusion cooperates with the clearance groove.

[0009] In another preferred embodiment of the present invention, the box wall has a recessed platform, the end face of which is the sealing surface of the box; the end face of the box cover facing the box body has a protrusion, the end face of which is the sealing surface of the box cover, and the sealing ring is located between the sealing surface of the box body and the sealing surface of the box cover.

[0010] In another preferred embodiment of the present invention, reinforcing ribs are provided between the sealing ring and the sealing surface of the box body and the sealing surface of the box cover.

[0011] In another preferred embodiment of the present invention, the reinforcing ribs between the sealing ring and the sealing surface of the housing are multiple, and are respectively located on both sides of the connector; the reinforcing ribs between the sealing ring and the sealing surface of the housing cover are multiple, and are respectively located on both sides of the connector.

[0012] In another preferred embodiment of the present invention, the cross-section of the reinforcing ring is semi-circular.

[0013] In another preferred embodiment of the present invention, the sealing surface of the housing is provided with a plurality of fixing screw holes, and the threaded section of the connector is connected to the fixing screw holes.

[0014] In another preferred embodiment of the present invention, the recessed platform of the box wall is machined by milling.

[0015] In another preferred embodiment of the present invention, the sealed box has a cubic structure.

[0016] In another preferred embodiment of the present invention, the housing is provided with a fixing screw hole, the fixing screw hole including a threaded hole and a countersunk hole, the depth of the countersunk hole being greater than the length of the threaded section of the connector.

[0017] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:

[0018] 1. The sealing box of the present invention includes a box body and a box cover, as well as a connector for fixing, and a sealing ring is used between the box body and the box cover. When the connector is tightened, the locking force of the connector compresses the sealing ring, thereby forming a waterproof structure and achieving a sealing effect. At the same time, the diameter of the sealing ring through hole is smaller than the diameter of the smooth rod section, thereby forming an interference fit and further enhancing the waterproof performance between the connector and the sealing ring. In addition, the diameter of the smooth rod section is smaller than the diameter of the threaded section. When the box cover is removed from the box body, the sealing through hole of the sealing ring will fit onto the threaded section, connecting the sealing ring to the box cover, avoiding the problem of the sealing ring falling off after the box cover is removed when the sealing box is installed on the side wall. Moreover, while the sealing ring is connected to the box cover through the connector, the sealing ring also connects the connector to the box cover, without having to remove each connector and set it aside. The cooperation between the connector and the sealing ring ensures that the connector and the sealing ring remain connected to the box cover after disassembly, simplifying the disassembly and assembly process and improving work efficiency.

[0019] 2. In this invention, the combination of the through hole protrusion and the clearance groove, along with the combination of the sealing ring through hole and the smooth rod section, allows the connector to easily align with the connecting hole of the housing and the fixing screw hole of the housing, simplifying the installation process and improving work efficiency.

[0020] 3. By setting a fixed screw hole with a countersunk hole and limiting the depth of the countersunk hole to be greater than the threaded section, the threaded section is located in the countersunk hole after exiting the threaded hole of the housing when the connector is disassembled, and will not enter the sealing ring through hole. The sealing ring through hole only contacts the smooth rod section of the connector. This not only achieves the purpose of connecting the sealing ring to the housing cover to prevent it from falling off, but also avoids the threaded section from entering the sealing ring through hole, thereby reducing the service life of the sealing ring.

[0021] 4. The sealing box of the present invention meets high waterproof requirements in underground tunnels and sewer environments. After repeated disassembly and assembly and debugging, the waterproof performance remains good, ensuring the safe operation of the equipment.

[0022] Advantages of additional aspects of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0036] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0037] For ease of description, the words "up," "down," "left," and "right" appearing in this invention only indicate that they are consistent with the up, down, left, and right directions of the accompanying drawings themselves. They do not limit the structure and are merely for the purpose of facilitating the description of this invention and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0038] Terminology Explanation: The terms "installation," "connection," "linking," and "fixing" in this invention should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction relationship between two components. Those skilled in the art can understand the specific meaning of the terms in this invention according to the specific circumstances.

[0039] Example 1

[0040] like Figures 1-8 As shown, one embodiment of the present invention describes a sealed box with a waterproof structure, including: a box body 1, a sealing ring 8, a box cover 2, and a connector 3 that connects the box body, the sealing ring, and the box cover together in sequence; the connector 3 has a threaded section 14 and a smooth section 13, the threaded section 14 is used for detachable connection with the box body, the sealing ring has a sealing ring through hole 9 that mates with the smooth section 13, the diameter of the sealing ring through hole 9 is smaller than the diameter of the smooth section 13, and the diameter of the smooth section 13 is smaller than the diameter of the threaded section 14.

[0041] The sealing box of this invention includes a box body and a box lid, as well as a connector for fixing, and a sealing ring is used between the box body and the box lid. When the connector is tightened, the locking force of the connector compresses the sealing ring, thereby forming a waterproof structure and achieving a sealing effect. At the same time, the diameter of the sealing ring through hole is smaller than the diameter of the smooth rod section, thereby forming an interference fit and further enhancing the waterproof performance between the connector and the sealing ring. In addition, the diameter of the smooth rod section is smaller than the diameter of the threaded section (because the sealing ring material itself can produce a certain degree of elastic deformation, the sealing ring through hole can pass through the threaded section and fit onto the smooth rod section). When the box lid is removed from the box body, the sealing through hole of the sealing ring will fit onto the threaded section, connecting the sealing ring to the box lid, avoiding the problem of the sealing ring falling off after the box lid is removed when the sealing box is installed on the side wall. Moreover, while the sealing ring is connected to the box lid through the connector, the sealing ring also connects the connector to the box lid, without having to remove each connector and set it aside. The fit between the connector and the sealing ring ensures that both remain attached to the cover after disassembly, simplifying the assembly and disassembly process and improving work efficiency.

[0042] The end face of the box cover facing the box body has a through hole protrusion, and the end face of the sealing ring facing the box cover is provided with a relief groove 11, and the through hole protrusion cooperates with the relief groove 11.

[0043] To facilitate alignment of the connector with the connecting holes (i.e., the fixing screw holes in this invention) on the housing body after the connector passes through the cover, the bolt holes on the cover for the connector are generally larger than the major diameter of the threaded section of the connector. However, the diameter of the smooth section in this invention is smaller than the diameter of the threaded section. Therefore, the large gap between the smooth section and the screw hole makes it difficult to align the connector with the connecting hole in the housing body, requiring the connector to be shaken back and forth during installation. In this invention, a through-hole protrusion is provided on the cover corresponding to the position of the connecting hole in the housing body. This through-hole protrusion mates with the clearance groove of the sealing ring, and the clearance groove is concentric with the through-hole of the sealing ring. The through-hole of the sealing ring and the smooth section of the connector have an interference fit, allowing the connector to easily align with the connecting hole in the housing body, simplifying the installation process and improving work efficiency.

[0044] The following is a detailed description of each component:

[0045] Figure 1 In this invention, the application includes a box body 1 and a box cover 2, as well as a connector 3 for fixing. A sealing ring 8 is used between the box body 1 and the box cover 2. When the connector 3 is tightened, the locking force of the connector 3 is used to press the sealing ring 8 into place, thereby forming a waterproof structure.

[0046] Figure 2This is a three-dimensional view of the enclosure 1. The cross-section of the enclosure can be rectangular, circular, or other shapes. A sealing surface 4 is shifted downwards from one end face of the enclosure to accommodate the sealing ring 8. The sealing surface 4 requires high flatness and smoothness to ensure waterproofing; it is typically precision-machined with a milling cutter followed by polishing. A ring of fixing screw holes 5 is evenly arranged on the sealing surface 4. The arrangement of the fixing screw holes 5 on the sealing surface 4 enhances waterproofing at the connection points and simplifies the structure of the sealing ring 8, thereby increasing reliability and simplifying on-site installation.

[0047] Figure 3 This is a 3D view of the box cover 2. The box cover has a sealing surface 6, which also needs to ensure flatness and smoothness. On the sealing surface 6 of the box cover, a ring of through-hole bosses 7 is arranged corresponding to the positions of the fixing screw holes 5 on the box body. In the middle of each through-hole boss 7 is a through hole for the connector 3. The boss is a ring-shaped rib stretched out from the hole for the installation and positioning of the sealing ring 8.

[0048] Figure 4 This is the side where the sealing ring 8 fits against the sealing surface 4 of the housing. Its shape is consistent with the sealing surface 4 of the housing, and the sealing ring through hole 9 also corresponds to the position of the fixing screw hole 5 on the housing 1. A partial magnification of the circle shows that the surface of the sealing ring 8 is provided with two reinforcing ring ribs 10. These are annular ribs with a semi-circular protrusion that are adapted to the shape of the sealing ring 8. When the housing 1 and the cover 2 are pressed together, the reinforcing ring ribs 10 are compressed first. Since the reinforcing ring ribs 10 can bear a greater amount of pressure, they are compressed the most thoroughly, thus forming a locally reinforced sealing ring water-locking structure. The two reinforcing ring ribs 10 form two water-locking structures, further enhancing the waterproof performance.

[0049] Figure 5 It is the side where the sealing ring 8 fits against the box cover 2, and it is also equipped with two reinforcing ring ribs 10.

[0050] Figure 6 yes Figure 5 As can be seen from the enlarged sectional view of AA, a relief groove 11 is provided at the sealing ring through hole 9, and a circular reinforcing rib 10 is provided at the bottom of the relief groove 11. After installation, the through hole boss 7 and the circular reinforcing rib 10 are pressed together, which can also locally enhance the sealing performance and individually enhance the sealing effect at each of the three connectors.

[0051] Figure 7 This is a front view of the sealing box of the present invention. Figure 8A partial section at point BB is enlarged. Between the sealing surface 4 of housing 1 and the sealing surface 6 of cover 2 is a sealing ring 8. After tightening the connector 3, the reinforcing rings 10 of the sealing ring 8 can be flattened (the figure shows the interference fit, but in actual use, it is flattened). Connector 3 has a flat washer 12, and connector 3 and flat washer 12 are used together. Connector 3 differs from ordinary bolts; it has a threaded head 14 and a smooth shaft 13 between the nut and the threaded head 14. The sealing ring through-hole 9 has an interference fit with the smooth shaft 13 of connector 3, and the sealing ring 8 partially wraps around the smooth shaft 13, further enhancing waterproofing. Furthermore, because the threaded head 14 can hold the sealing ring 8, connector 3 can attach the sealing ring 8 to cover 2 during disassembly and assembly, facilitating removal and installation. This is especially important when the equipment is mounted on a wall; if the sealing ring cannot be fixed to housing 1 or cover 2, disassembly and assembly in a vertical position are difficult.

[0052] Example 2

[0053] The difference between Embodiment 2 and Embodiment 1 is that the fixing screw hole has a countersunk hole 15, and the depth of the countersunk hole 15 is greater than the length of the threaded section 14 of the connector 3 (e.g., Figure 9 (As shown).

[0054] By setting a fixed screw hole with a countersunk hole and limiting the depth of the countersunk hole to be greater than the threaded section, when the connector is disassembled, the threaded section is located in the countersunk hole after exiting the threaded hole of the housing and will not enter the sealing ring through hole. The sealing ring through hole only contacts the smooth section of the connector. This not only connects the sealing ring to the housing cover to prevent it from falling off, but also avoids the threaded section from entering the sealing ring through hole, thereby reducing the service life of the sealing ring.

[0055] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
