Description

Technical Field

[0001] This utility model relates to the field of composite conduit technology, and in particular to a moisture-proof and flame-retardant composite conduit structure. Background Technology

[0002] Composite conduit is a widely used conduit material in building construction. It consists of two layers: an inner plastic tube and an outer metal or cement layer. It offers excellent insulation, corrosion resistance, and fire resistance, ensuring the long-term safe operation of electrical wires within it. Composite conduit is widely used in electrical wiring projects in residential buildings, office buildings, factories, and other structures, especially in applications with high requirements for fire resistance, explosion protection, and corrosion resistance. Furthermore, it is also used in special applications such as bridges and tunnels.

[0003] The existing technical solutions mentioned above have the following drawbacks: the existing composite conduit structure is too simple, the moisture-proof and flame-retardant effects are insufficient, and it cannot meet the actual use needs, resulting in low practicality of composite conduits. Utility Model Content

[0004] The purpose of this invention is to provide a moisture-proof and flame-retardant composite conduit structure.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A moisture-proof and flame-retardant composite conduit structure includes a composite conduit body, a groove on the inner side of the composite conduit body, a flame-retardant layer on the outer side of the composite conduit body, a fixing block fixedly connected to the outer side of the flame-retardant layer, a bolt inserted into the inside of the fixing block, a nut sleeved on the outside of the bolt, a flame-retardant tube installed on the inner side of the composite conduit body, and a locking block fixedly connected to the outer side of the flame-retardant tube.

[0007] By adopting the above technical solution, flame-retardant structures are added to both the inner and outer sides of the composite conduit body. The outer flame-retardant layer is made of metal tubing, and the inner flame-retardant tubing is made of glass fiber reinforced plastic material, which can provide a good flame-retardant effect. The double-layer flame retardancy can prevent short circuits inside the conduit from burning to external equipment. At the same time, the flame-retardant tubing can be snapped into the composite conduit.

[0008] Furthermore, a first mounting groove is reserved between the composite conduit body and the flame-retardant layer, and a second mounting groove is reserved between the composite conduit body and the flame-retardant pipe. A first moisture-proof layer is installed inside the first mounting groove, and a second moisture-proof layer is installed inside the second mounting groove.

[0009] By adopting the above technical solution, and by adding a moisture-proof layer between the composite conduit and the flame-retardant layer and between the flame-retardant pipe, the moisture-proof effect of the conduit can be improved by adding a double moisture-proof layer, preventing the internal circuitry from getting damp.

[0010] Furthermore, four slots and blocks are evenly spaced in a ring, and the slots and blocks are engaged and connected. Two sets of flame-retardant layers and fixing blocks are symmetrically arranged, with four fixing blocks in each set.

[0011] By adopting the above technical solution and through the connection between the card block and the card slot, rapid installation between flame-retardant pipes and composite conduits can be achieved.

[0012] Furthermore, two sets of bolts and nuts are symmetrically arranged, with two bolts and nuts in each set. The bolts extend through the fixing block to the outside of the fixing block, and the bolts and nuts are threaded together.

[0013] By adopting the above technical solution, the flame-retardant layer can be spliced ​​and fixed by the cooperation of bolts and nuts, and splicing and installation can be carried out at any time.

[0014] Furthermore, four of the second mounting slots and the first moisture-proof layer are distributed in a ring at equal intervals. The second mounting slots and the first moisture-proof layer are engaged and connected, and the first mounting slots and the second moisture-proof layer are engaged and connected.

[0015] By adopting the above technical solution and adding a moisture-proof layer, the effect of moisture protection is improved.

[0016] In summary, the beneficial technical effects of this utility model are as follows:

[0017] It adopts a flame-retardant layer, a flame-retardant pipe, a first moisture-proof layer, and a second moisture-proof layer. Flame-retardant structures are added to both the inner and outer sides of the composite conduit body. Both the flame-retardant layer and the flame-retardant pipe can provide flame-retardant effects for the composite conduit. At the same time, a moisture-proof layer is added between the composite conduit, the flame-retardant layer, and the flame-retardant pipe to provide moisture protection. The structures can be spliced ​​and installed for easy operation. It can be used according to the actual needs of the site, resulting in a convenient user experience. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Reference Figure 1-3 A moisture-proof and flame-retardant composite conduit structure includes a composite conduit body 1, a slot 2 on the inner side of the composite conduit body 1, a flame-retardant layer 3 on the outer side of the composite conduit body 1, a fixing block 4 fixedly connected to the outer side of the flame-retardant layer 3, a bolt 5 inserted into the inside of the fixing block 4, and a nut 6 sleeved on the outer side of the bolt 5, a flame-retardant tube 7 installed on the inner side of the composite conduit body 1, a slot 8 fixedly connected to the outer side of the flame-retardant tube 7, a first mounting groove 9 reserved between the composite conduit body 1 and the flame-retardant layer 3, and a second mounting groove 10 reserved between the composite conduit body 1 and the flame-retardant tube 7, a first moisture-proof layer 11 installed inside the first mounting groove 9, and a second moisture-proof layer 12 installed inside the second mounting groove 10. Flame-retardant structures are added to both outer sides. The outer flame-retardant layer 3 is made of metal tubing, while the inner flame-retardant tube 7 is made of glass fiber reinforced plastic material, providing excellent flame-retardant performance. The double-layer flame retardancy prevents short circuits within the conduit from spreading to external equipment. The flame-retardant tube 7 can be snapped into the composite conduit. By adding a moisture-proof layer between the composite conduit, the flame-retardant layer 3, and the flame-retardant tube 7, the moisture-proof effect of the conduit is improved, preventing internal wiring from getting damp. The moisture-proof layer is made of polyurethane foam. The flame-retardant layer 3 can be spliced ​​and fixed using bolts 5 and nuts 6, allowing for easy splicing and installation.

[0024] like Figure 1-3 As shown, there are four equally spaced slots 2 and four equally spaced blocks 8 in a ring. The slots 2 and blocks 8 are engaged and connected. The flame-retardant layer 3 and the fixing block 4 are symmetrically arranged in two groups, with four fixing blocks 4 in each group. The bolts 5 and the nuts 6 are symmetrically arranged in two groups, with two bolts 5 and two nuts 6 in each group. The bolts 5 pass through the fixing block 4 and extend to the outside of the fixing block 4. The bolts 5 and the nuts 6 are threadedly connected. The second mounting groove 10 and the first moisture-proof layer 11 are equally spaced in a ring. The second mounting groove 10 and the first moisture-proof layer 11 are engaged and connected. The first mounting groove 9 and the second moisture-proof layer 12 are engaged and connected.

[0025] The implementation principle of this embodiment is as follows: the flame-retardant tube 7 is engaged with the groove 2 on the inner side of the composite conduit body 1 by the outer clamping block 8, the first moisture-proof layer 11 is installed into the second mounting groove 10, the second moisture-proof layer 12 is installed on the outer side of the composite conduit body 1, and the flame-retardant layer 3 is sleeved on the outer side of the second moisture-proof layer 12. The two flame-retardant layers 3 are connected by passing the bolt 5 through the fixing block 4, and then locked and fixed by the nut 6. The installation of the two sets of flame-retardant layers 3 is completed. The flame-retardant layer 3 and the flame-retardant tube 7 play a flame-retardant role, and the two sets of moisture-proof layers can play a moisture-proof role, making the composite conduit more practical.

[0026] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
