Description

Technical Field

[0001] This utility model relates to the field of cable sheaths, and more particularly to building control cables with lightweight, anti-aging sheaths. Background Technology

[0002] The sheath of building control cables is usually made of polyvinyl chloride (PVC), which has good insulation properties and mechanical strength, and can effectively protect the conductors inside the cable from damage by the external environment.

[0003] Common cable sheaths are usually one-piece sleeves made of polyvinyl chloride (PVC) material, which can protect the cable. However, they lack quick-installation structures, making it impossible to quickly install the cable inside the sheath. When the cable needs to be laid out, it is necessary to insert the cable into the sheath from one end and pull it out from the other end. Replacing the cable is also quite troublesome, which is not only time-consuming and laborious, but also affects the efficiency of installing and removing the sheath, thus reducing the practicality of the cable sheath.

[0004] Therefore, to address the lack of a quick-installation structure for the aforementioned cable sheaths, which prevents rapid installation of the cables within the sheaths, a lightweight, anti-aging sheath for building control cables can be designed. Rotating the mounting plate causes the first movable rod to rotate, which in turn causes its lower end to rotate outside the shaft, thus adjusting the position of the mounting plate. Simultaneously, rotating the connecting plate causes the second movable rod to rotate outside the shaft, allowing the connecting plate to move to the upper side of the mounting plate. Furthermore, by screwing the internal angle screw into the fixing hole, the mounting plate and connecting plate are secured, achieving rapid installation. Utility Model Content

[0005] To overcome the common problem that cable sheaths lack quick-installation structures, making it impossible to quickly install cables inside the sheath, when cable routing is required, the cable must be threaded through one end of the sheath and pulled out from the other end. Replacing the cable is also quite troublesome, which is not only time-consuming and labor-intensive, but also affects the efficiency of sheath installation and disassembly, thus reducing the practicality of cable sheaths.

[0006] The technical solution of this utility model is as follows: a lightweight, anti-aging sheathed building control cable, including a sheath body; it also includes a first connecting strip, a second connecting strip, corner brackets, a pivot, a first movable rod, a second movable rod, a mounting plate, a connecting plate, and inner corner screws. The first connecting strip and the second connecting strip are symmetrically connected to the upper side of the sheath body, and four corner brackets are symmetrically installed on the outer sides of the first connecting strip and the second connecting strip. A pivot is provided on the inner side of the corner bracket, and the first movable rod and the second movable rod are symmetrically connected on the outer side of the pivot. A mounting plate is connected to the top of the first movable rod, and a connecting plate is installed on the top of the second movable rod. Inner corner screws are symmetrically connected at equal intervals on the top of the connecting plate.

[0007] Preferably, rotating the mounting plate can drive the first movable rod to rotate, and the rotation of the first movable rod will cause its lower end to rotate outside the rotating shaft, so as to adjust the position of the mounting plate. At the same time, rotating the connecting plate can drive the second movable rod to rotate outside the rotating shaft, so that the connecting plate can be moved to the upper side of the mounting plate. And by screwing the inner angle screw into the fixing hole, the mounting plate and the connecting plate can be fixed.

[0008] Preferably, the top of the first connecting strip and the mounting plate has a fixing hole corresponding to the position of the inner corner screw, and the lower end of the inner corner screw passes through the connecting plate and the mounting plate and connects to the fixing hole at the top of the first connecting strip.

[0009] Preferably, two sealing grooves are symmetrically formed on the inner side of the second connecting strip, and two sealing blocks are installed on the inner side of the first connecting strip at the positions corresponding to the sealing grooves.

[0010] Preferably, the inner side of the sheath body is provided with a cable sleeve, a plug is installed on the lower side wall of the cable sleeve, and a guide groove is opened on the inner side of the sheath body corresponding to the position of the plug, and the lower end of the plug is inserted into the interior of the guide groove.

[0011] As a preferred embodiment, a support column is provided at the center of the cable conduit, and four partition plates are symmetrically connected at equal intervals on the side wall of the support column.

[0012] Preferably, four shielding layers are symmetrically arranged between the partitions, and an insulating sleeve is provided inside the shielding layer.

[0013] Preferably, one end of the partition plate is fused to the inner wall of the cable sleeve, and flame-retardant particles are filled between the partition plate and the cable sleeve.

[0014] The beneficial effects of this utility model are:

[0015] 1. Rotating the mounting plate can drive the first movable rod to rotate. The rotation of the first movable rod will cause its lower end to rotate on the outside of the rotating shaft, so as to adjust the position of the mounting plate. At the same time, rotating the connecting plate can drive the second movable rod to rotate on the outside of the rotating shaft, so that the connecting plate can be moved to the upper side of the mounting plate. And by screwing the inner angle screw into the fixing hole, the mounting plate and the connecting plate can be fixed. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4This utility model provides an embodiment of a lightweight, anti-aging sheathed building control cable, comprising a sheath body 1; and further comprising a first connecting strip 2, a second connecting strip 3, corner brackets 4, a rotating shaft 5, a first movable rod 6, a second movable rod 7, a mounting plate 8, a connecting plate 9, and an inner corner screw 10. The first connecting strip 2 and the second connecting strip 3 are symmetrically connected to the upper side of the sheath body 1, and four corner brackets 4 are symmetrically installed on the outer sides of the first connecting strip 2 and the second connecting strip 3. A rotating shaft 5 is provided on the inner side of the corner bracket 4, and the first movable rod 6 and the second movable rod 7 are symmetrically connected to the outer side of the rotating shaft 5. The top of the first movable rod 6 is connected to... There is a mounting plate 8, and a connecting plate 9 is installed on the top of the second movable rod 7. The top of the connecting plate 9 is symmetrically connected with internal angle screws 10 at equal intervals. By rotating the mounting plate 8, the first movable rod 6 can be rotated. The rotation of the first movable rod 6 will cause its lower end to rotate outside the rotating shaft 5, so as to adjust the position of the mounting plate 8. At the same time, by rotating the connecting plate 9, the second movable rod 7 can be rotated outside the rotating shaft 5, so that the connecting plate 9 can be moved to the upper side of the mounting plate 8. And by screwing the internal angle screws 10 into the fixing holes 11, the mounting plate 8 and the connecting plate 9 can be fixed.

[0023] Please see Figures 1-4 In this embodiment, a fixing hole 11 is provided at the top of the first connecting strip 2 and the mounting plate 8 corresponding to the position of the inner angle screw 10. The lower end of the inner angle screw 10 passes through the connecting plate 9 and the mounting plate 8 and connects to the fixing hole 11 at the top of the first connecting strip 2. By screwing the inner angle screw 10 into the fixing hole 11, the connecting plate 9 and the mounting plate 8 can be fixedly connected to the first connecting strip 2, thereby preventing the first connecting strip 2 from detaching from the second connecting strip 3 and improving the stability of the connection. Two sealing grooves 12 are symmetrically provided on the inner side of the second connecting strip 3, and the inner side of the first connecting strip 2 is corresponding to the sealing grooves 12. Two sealing blocks 13 are installed at the position of the groove 12. By embedding the sealing blocks 13 into the sealing groove 12, the sealing performance at the connection between the first connecting strip 2 and the second connecting strip 3 can be improved. A cable sleeve 14 is provided inside the sheath body 1. An insert block 15 is installed on the lower side wall of the cable sleeve 14. A guide groove 16 is opened on the inner side of the sheath body 1 corresponding to the position of the insert block 15. The lower end of the insert block 15 is inserted into the interior of the guide groove 16. The cable sleeve 14 can be moved along the guide groove 16 inside the sheath body 1 through the insert block 15 to achieve the effect of quick guidance and installation.

[0024] Please see Figures 1-4In this embodiment, a support column 17 is provided at the center of the cable sleeve 14. Four partition plates 18 are symmetrically connected at equal intervals on the side wall of the support column 17. The rubber support column 17 and partition plates 18 can support the inner wall of the cable sleeve 14, improving its stability and plasticity during operation. Four shielding layers 19 are symmetrically arranged between the partition plates 18, and an insulating sleeve 20 is provided inside the shielding layer 19. The shielding layer 19 can be used to reduce electromagnetic interference, and the insulating sleeve 20 can be used to cover the conductive copper wire to avoid leakage and electric shock. One end of the partition plate 18 is fused to the inner wall of the cable sleeve 14, and flame-retardant particles are filled between the partition plate 18 and the cable sleeve 14. By filling the inside of the cable sleeve 14 with flame-retardant particles, its high temperature resistance and fire resistance can be improved.

[0025] During operation, the first connecting strip 2 and the second connecting strip 3 are first separated, and the cable sleeve 14 is simultaneously placed inside the sheath body 1. The cable sleeve 14 is moved along the guide groove 16 inside the sheath body 1 by the insert block 15 to achieve the effect of quick guidance and installation. After the cable sleeve 14 is installed, the sealing block 13 can be embedded in the sealing groove 12 to improve the sealing of the connection between the first connecting strip 2 and the second connecting strip 3. At the same time, by rotating the mounting plate 8, the first movable rod 6 is rotated. The rotation of the first movable rod 6 will cause its lower end to rotate outside the rotating shaft 5 to adjust the position of the mounting plate 8. At the same time, by rotating the connecting plate 9, the second movable rod 7 can be rotated outside the rotating shaft 5, so that the connecting plate 9 can be moved to the upper side of the mounting plate 8. By screwing the inner angle screw 10 into the fixing hole 11, the mounting plate 8 and the connecting plate 9 can be fixed.

[0026] Through the above steps, rotating the mounting plate 8 can drive the first movable rod 6 to rotate. The rotation of the first movable rod 6 will cause its lower end to rotate outside the rotating shaft 5, thereby adjusting the position of the mounting plate 8. At the same time, rotating the connecting plate 9 can drive the second movable rod 7 to rotate outside the rotating shaft 5, thereby allowing the connecting plate 9 to move to the upper side of the mounting plate 8. By screwing the inner angle screw 10 into the fixing hole 11, the mounting plate 8 and the connecting plate 9 can be fixed. This solves the problem of common cable sheaths, which are usually one-piece sleeves made of polyvinyl chloride material. They can protect the cable, but lack a quick-installation structure, making it impossible to quickly install the cable inside the sheath. When it is necessary to install the cable, the cable needs to be inserted from one end of the sheath and pulled out from the other end. It is also quite troublesome when the cable needs to be replaced. It is not only time-consuming and laborious, but also affects the installation and disassembly efficiency of the sheath, thus reducing the practicality of the cable sheath.
