Description
Technical Field
[0001] This utility model relates to the field of building supplies technology, and in particular to a snap-fit type pressure-resistant protective shell for building conduits. Background Technology
[0002] In building construction and various engineering projects, laying electrical wires and cables typically requires the extensive use of conduits as protective channels for the conductors. These conduits are often concealed beneath walls, floors, or overlays. During construction, especially in subsequent stages such as floor leveling, plastering, equipment handling, or periods of frequent personnel movement, conduits buried shallowly or exposed to the work surface are highly susceptible to external pressure, which can cause them to collapse, deform, or even break.
[0003] Chinese Patent Announcement No. CN203488853U provides a conduit protection cover. This design features a "conduit locking groove on the upper part of the locking shell, with a locking tooth 1 inside the groove; a conduit locking groove on the lower part of the locking shell; an adhesive layer on the bottom of the locking shell; and a locking tooth 2 on the locking plate. The locking plate is inserted into the locking groove, and the locking tooth 1 engages with the locking tooth 2. It employs double-layer protection to safeguard the conduit, ensuring its safety, ease of use, simple operation, and extended service life."
[0004] The aforementioned device achieves engagement solely through locking teeth one and two during use. However, the locking teeth may wear down or break during long-term use, significantly reducing the engagement effectiveness of the outer casing and thus limiting the device's usability.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0028] Reference Figures 1 to 4 A pressure-resistant protective shell for building construction using a snap-fit type conduit, comprising:
[0029] The protective component 1 includes an inner layer 11 and an outer layer 13 disposed outside the inner layer 11; wherein, the inner layer 11 is in contact with the cables in the building construction work, while the outer layer 13 is in contact with the external environment. Therefore, the outer layer 13 needs to have good load-bearing capacity and protective effect.
[0030] And, the snap-fit assembly 2 includes a plug-in plate 22, a first limiting ring 26 and a second limiting ring 27 disposed inside the inner layer 11; wherein, the plug-in plate 22 is inserted into the inner layer 11 of another protective assembly 1 along with the inner layer 11, the first limiting ring 26 and the second limiting ring 27 together form a ring-like structure, and the outer wall of the first limiting ring 26 is provided with a groove, and the outer wall of the second limiting ring 27 is provided with a protrusion, to ensure the connection area of the first limiting ring 26 and the second limiting ring 27.
[0031] In this process, the first limiting ring 26 is inserted between the first limiting ring 26 and the second limiting ring 27 by interlocking adjacent inner layers 11, thereby achieving the connection of continuous inner layers 11.
[0032] Specifically, the protective component 1 also includes support rings 12 that are fixedly connected at equal intervals to the end face of the inner layer 11. The end face of the support rings 12 is connected to the inner wall of the outer layer 13. A plug-in portion 14 is fixedly connected to one side of the outer wall of the inner layer 11, and an embedded portion 15 adapted to the plug-in portion 14 is provided on the inner wall of the inner layer 11 away from the plug-in portion 14. The support rings 12 are equidistantly located on the end face of the inner layer 11, and their two sides are connected to the inner layer 11 and the outer layer 13 respectively, thereby further enhancing the protective effect of the conduit. At the same time, the plug-in portion 14 and the embedded portion 15 are provided on both sides of the inner layer 11, and adjacent inner layers 11 can be continuously plugged in and installed through the plug-in portion 14 and the embedded portion 15.
[0033] When in use, since the inner layer 11, the support ring 12 and the outer layer 13 are a whole, they together form the main body of the conduit to protect the cable. When the conduit needs to be assembled during the building construction process, the insertion part 14 of the outer wall of the inner layer 11 of one protective component 1 is inserted into the embedded part 15 of the inner wall of the inner layer 11 of another protective component 1, and the depths of the insertion part 14 and the embedded part 15 are matched to ensure the stable insertion of the subsequent snap-fit component 2.
[0034] In summary, the multi-layered composite design of the protective component 1 can ensure the load-bearing protection effect of the conduit body. At the same time, the protruding plug-in part 14 and the internal embedded part 15 can enable the continuous adjacent protective components 1 to be plugged in and installed.
[0035] Reference Figure 3 and Figure 4 The snap-fit assembly 2 also includes a first fixing block 21 arranged in a ring array on the end face of the plug-in portion 14, and the outer wall of the plug-in plate 22 is fixedly connected to the outer wall of the first fixing block 21. Multiple first fixing blocks 21 and plug-in plates 22 are arranged in a ring on the outside of the plug-in portion 14, and a straight edge is retained between the plug-in plate 22 and the first fixing block 21 for subsequent plugging.
[0036] Specifically, the end face of the embedded part 15 is fixedly connected to a second fixing block 23 arranged in a ring. The outer wall of the second fixing block 23 has an inner cavity 24. The first limiting ring 26 and the second limiting ring 27 are rotatably connected by a connecting rod 25. The number and position of the second fixing blocks 23 are adapted to the first fixing blocks 21. The second fixing blocks 23 are fixedly connected to the end face of the embedded part 15. By inserting one inner layer 11, the plug-in plate 22 inside it is engaged with the first limiting ring 26 and the second limiting ring 27 in the other inner layer 11, thereby realizing the connection between the two adjacent inner layers 11.
[0037] In use, the plug-in plate 22 moves synchronously with the plug-in part 14 on the outer wall of the inner layer 11 via the first fixing block 21, moving towards the inner side of the first limiting ring 26 and the second limiting ring 27. When the plug-in plate 22 contacts the first limiting ring 26 and the second limiting ring 27, since the connection between the first limiting ring 26 and the second limiting ring 27 is concave and convex respectively, and the first limiting ring 26 and the second limiting ring 27 are connected by the connecting rod 25, the two limiting rings can rotate within the inner cavity 24 opened on the outer wall of the second fixing block 23, thereby ensuring that there is a certain channel for the plug-in plate 22 to be inserted.
[0038] In summary, the first fixing block 21 and the second fixing block 23 connect the plug-in plate 22 and the first limiting ring 26 and the second limiting ring 27. The design of multiple plug-in structures can ensure the tightness of the connection between the two adjacent protective components 1. At the same time, the design of the first limiting ring 26 and the second limiting ring 27 as rings adapted to the plug-in plate 22 can further ensure the snap-fit effect of the plug-in plate 22.
[0039] Reference Figure 4 and Figure 5 A spring 29 is fixedly installed on the outer wall of the second fixing block 23. The end of the spring 29 is fixedly connected to the outer wall of the outer connecting plate 28 integrally formed on the end face of the first limiting ring 26 and the second limiting ring 27. The first limiting ring 26 and the second limiting ring 27 are movably connected by a connecting rod 25. Their movement space is within the inner cavity 24 of the outer wall of the second fixing block 23. At the same time, the outer connecting plate 28, which is fixedly connected to the outer wall of the first limiting ring 26 and the second limiting ring 27, is connected to the second fixing block 23 by the spring 29, so that it can be used in conjunction with the connecting rod 25. This ensures that the first limiting ring 26 and the second limiting ring 27 can reset themselves to realize the next insertion action.
[0040] Specifically, the outer layer 13 has a pull plate 3 and a protrusion 4 integrally formed on the outer wall of the pull plate 3, which are fixedly connected to the end face. The pull plate 3 is provided on both sides of the end face of the outer layer 13 near the edge, and the top of the outer wall of the pull plate 3 is provided with the protrusion 4. By controlling the pull plates 3 on the outer walls of the two different outer layers 13 to move away from each other, the two adjacent protective components 1 can be quickly separated, thereby ensuring that there are enough fulcrums for the operator to disassemble the conduit.
[0041] In use, the outer walls of the first limiting ring 26 and the second limiting ring 27 are provided with external plates 28. The external plates 28 are fixedly connected to the second fixing block 23 by springs 29. During the opening process of the first limiting ring 26 and the second limiting ring 27, the springs 29 are compressed to ensure that the limiting rings have a certain reset capability during the opening process. When it is necessary to disassemble the conduit, the operator can control the pull plate 3 to both sides to provide a force point for the protective component 1, which facilitates the quick disassembly of the conduit.
[0042] In summary, the spring 29 and the connecting rod 25 work together to achieve continuous engagement of the plug-in plate 22, and the pull plate 3 on the outer end face of the outer layer 13 facilitates the quick disassembly of the device.
[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
