Description

Technical Field

[0001] The invention belongs to the technical field of cables, and in particular relates to a cable protection tube supporting device. Background Art

[0002] Cable refers to materials used for power, electrical and related transmission purposes. Cables are usually placed in protective tubes to prevent the outer sheath or even the inner core of the cable from being damaged. The protective tube is usually fixed on the wall or underground. For the installation method of fixing on the wall, the cable falls to the bottom of the protective tube by gravity, such as Fig.23 As shown, because it is installed on the wall, it is occasionally hit. For example, when a new cable conduit is installed around the conduit, the installation tool may touch the bottom of the conduit. At this time, the conduit protects the cable, but the bottom of the conduit may be damaged and broken. When the bottom of the conduit is damaged, the impact force may damage the cable that falls on the lower side of the conduit.

[0003] In addition, the protective tube needs to have a certain wall thickness. On the one hand, it is to protect the cable. On the other hand, when it is installed on the wall, the protective tube will not be deformed when the clamp on the wall clamps the protective tube. Therefore, the thickness of the protective tube is generally much greater than the thickness required to protect the cable, resulting in a waste of protective tube materials.

[0004] The present invention designs a cable protection tube supporting device to solve the above problems. Summary of the invention

[0012] As a preferred solution, the driving magnetic ring is composed of two semi-annular magnetic ring components, one end of the two magnetic ring components is hinged, and the other end is connected by a first fixing bolt.

[0013] As a preferred solution, when installing the protective tube, a pressure ring mechanism will be installed on the wall; the pressure ring mechanism includes an upper pressure ring assembly, a second fixing bolt, and a lower pressure ring assembly. The upper pressure ring assembly and the lower pressure ring assembly are swing-mounted on the wall, and the upper pressure ring assembly and the lower pressure ring assembly are connected on the side away from the wall by the second fixing bolt; the protective tube is nested between the upper pressure ring assembly and the lower pressure ring assembly.

After the cable is inserted, the two support structures can be controlled to swing upward, and the cable is pushed upward by the ends of the two support structures away from the first rotating shaft, so that the cable is clamped between the two support structures, and an annular gap is formed between the cable and the protective tube, so as to prevent the installation tool from hitting the bottom of the protective tube and damaging the cable in the protective tube due to damage to the bottom of the protective tube when installing a new cable protective tube.

[0018] 2. When adding new cables later, it is necessary to control the two supporting structures to swing to a horizontal state first, and then insert the cables, and then control the two supporting structures to swing upward to clamp the cables. That is, the device designed by the present invention can be used for different numbers of cables.

[0019] 3. The protective tube in the present invention can be designed as a thin tube because it does not need to bear the supporting function of the cable, thus saving protective tube materials.

[0020] 4. During use, when one of the third fixing bolts becomes loose, the upper pressure ring assembly will reset from the deformed state and squeeze the card plate, causing the card plate to disengage from between the limit plate and the fixed pad. The card plate's limiting ability on the upper pressure ring assembly fails, and the upper pressure ring assembly loses pressure on the protective tube. At this time, the worm wheel and worm on the lower side will release the meshing relationship and disengage, and the supporting structure on the lower side will swing downward under the gravity of the cable to become horizontal; the cable will be pressed on the lower side of the protective tube; the longer length of the protective tube contact surface presses the protective tube, which can better protect the protective tube compared to the cable directly squeezing the supporting structure that has lost its wall support and then pressing on the protective tube.

[0047] like Figure 1 , 2 As shown, a driving magnetic ring 2 is installed on the outer side of the protective tube 1. Figure 6 As shown, the driving magnetic ring 2 is composed of two semi-annular magnetic ring assemblies 6, one end of the two magnetic ring assemblies 6 is hinged, and the other end is connected by a first fixing bolt 7. The driving magnetic ring 2 cooperates with the transmission magnetic ring 20 installed in the transition ring 19.

[0048] When the driving magnetic ring 2 is controlled to rotate, the driving magnetic ring 2 will drive the transmission magnetic ring 20 to rotate, the rotation of the transmission magnetic ring 20 will drive the transition ring 19 to rotate, the rotation of the transition ring 19 will drive the gear ring 32 to rotate, the rotation of the gear ring 32 will drive the transmission gear 31 to rotate, the rotation of the transmission gear 31 will drive the worm 27 to rotate, the rotation of the worm 27 will drive the worm wheel 29 meshing with it to rotate, the rotation of the worm wheel 29 will drive the first rotating shaft 28 to rotate, and the rotation of the first rotating shaft 28 will drive the corresponding support structure 21 to rotate.

[0049] like Fig.17 , 18 As shown, in the present invention, when the upper pressure ring assembly 8 and the lower pressure ring assembly 10 in the pressure ring mechanism 3 have not yet applied pressure to the protective tube 1, under the action of the elastic pad 25, one end of the slidable support 23 is tightly against the inner wall surface of the protective tube 1, and the worm wheel 29 installed on the slidable support 23 and the corresponding worm 27 are in a critical state of disengagement and engagement. At this time, the rotation of the worm 27 will not drive the worm wheel 29 to rotate.

[0050] The function of the arc-shaped magnetic block 18 in the present invention is to detect and adjust the position of the regulating ring 4, to ensure that one side of the slidable support 23 installed in the regulating ring 4 is located at the lower side of the regulating ring 4, and the two supporting structures 21 are distributed up and down in the regulating ring 4; when adjusting the position of the regulating ring 4, the external magnet is placed on the outside of the protective tube 1, and the suction force exerted on the external magnet is observed. The position of the regulating ring 4 is judged by the size of the suction force. When it is observed that the position of the regulating ring is not adjusted properly, the driving magnetic ring 2 can be rotated in the reverse direction. At this time, because the supporting structure on the meshing side of the worm wheel and the worm is close to the inner wall surface of the regulating ring, when the driving magnetic ring is rotated in the reverse direction, the supporting structure will be limited by the inner wall surface of the regulating ring and cannot swing. At this time The reverse rotation of the driving magnetic ring will drive the transmission magnetic ring 20 to rotate, the rotation of the transmission magnetic ring 20 will drive the transition ring 19 to rotate, the rotation of the transition ring 19 will drive the gear ring 32 to rotate, the rotation of the gear ring 32 will drive the transmission gear 31, the worm 27, the worm wheel 29, the first rotating shaft 28 and the support structure 21 to rotate circumferentially around the axis of the regulating ring 4. During this process, the support structure on the side where the worm wheel and the worm are not engaged will swing freely with the rotation of the regulating ring, but when it is properly adjusted, the support structure will automatically fall close to the inner wall of the regulating ring under the action of its own gravity; when it is observed that the suction force on the external magnet reaches the maximum, stop rotating the driving magnetic ring 2, and the adjustment of the regulating ring 4 is completed.

[0051] The transition ring 19 designed in the present invention has a conical surface, and the design of the conical surface can ensure that the cable 35 can slide smoothly onto the two supporting structures 21 when inserted, and will not be stuck by the transition ring 19.

[0052] The supporting structure 21 designed in the present invention is crescent-shaped. Fig.17 , 18 As shown, when the support structure 21 is close to the inner wall of the regulating ring 4 and is in a horizontal state, the inserted cable 35 can slide forward close to the support structure 21 located at the lower side, as shown in FIG. Fig.21 As shown, after the cable 35 is inserted, the two support structures 21 can be controlled to swing upward, and the cable 35 can be pushed upward by the ends of the two support structures 21 away from the first rotating shaft 28, so that the cable 35 is clamped between the two support structures 21, and an annular gap is formed between the cable 35 and the protective tube 1, so as to prevent the installation tool from hitting the bottom of the protective tube 1 and damaging the cable 35 in the protective tube 1 when installing a new protective tube 1 for the cable 35 due to damage to the bottom of the protective tube 1.

[0053] The driving magnetic ring 2 designed in the present invention is a detachable structure. When in use, the two magnetic ring components 6 in the driving magnetic ring 2 are clamped on the outside of the protective tube 1, and then the two magnetic ring components 6 are linked together by the first fixing bolt 7 to form a complete magnetic ring.

[0054] When adding cables 35 later, it is necessary to control the two supporting structures 21 to swing to a horizontal state first, and then insert the cables 35, and then control the two supporting structures 21 to swing upward to clamp the cables 35. That is, the device designed in the present invention can be used for different numbers of cables 35.

[0055] The worm wheel 29 and the worm 27 designed in the present invention can play a self-locking function after the two supporting structures 21 swing upward.

[0056] There is a small gap between the regulating ring 4 and the protective tube 1 of the present invention, which can ensure that the regulating ring 4 slides smoothly in the protective tube 1, but the size of the gap will not cause the regulating ring 4 to shake in the protective tube 1 and affect the installation of the cable 35.

[0057] In the present invention, when the protective tube 1 passes through the slidable support 23 of the regulating ring 4, the slidable support 23 will slide relative to the regulating ring 4, so that the worm wheel 29 installed on the adjustable support and the corresponding worm 27 are engaged; and the elastic pad 25 is compressed.

[0058] When installing the protective tube 1, a pressing ring mechanism 3 will be installed on the wall; Figure 7 As shown, the pressing ring mechanism 3 includes an upper pressing ring assembly 8, a second fixing bolt 9, a lower pressing ring assembly 10, a fixing pad 11, a third fixing bolt 12, a support column 13, a clamping plate 14, a limiting plate 15, a pin 16, and a clamping ring 17, wherein Fig.11 As shown, two clamping rings 17 are installed at the upper and lower ends of one end of the support column 13, and the two clamping rings 17 are both clamping rings 17 with notches. A pin 16 is fixedly installed on the clamping ring 17 on the lower side, and an L-shaped limiting plate 15 is fixedly installed on the outer circumferential surface of the upper side of the support column 13; Figure 1 , 8 As shown in Figures 9 and 10, the support column 13 is mounted on the wall by a third fixing bolt 12, and a fixing pad 11 is installed between the support column 13 and the wall; the lower pressure ring assembly 10 is swingably mounted on the clamping ring 17 located at the lower side of the support column 13 by a pin shaft 16; the upper pressure ring assembly 8 is hinged on the clamping ring 17 located at the upper side of the support column 13, as shown in Figures 9 and 10. Fig. 9 , 10 As shown, a C-shaped clamping plate 14 is installed between the upper pressure ring assembly 8 and the fixed pad 11, and the lower end of the clamping plate 14 is inserted between the limit plate 15 and the support column 13, one side of the clamping plate 14 is close to the fixed pad 11, and the other side of the clamping plate 14 is close to the outer wall surface of the upper pressure ring assembly 8; the upper pressure ring assembly 8 and the lower pressure ring assembly 10 are connected by a second fixing bolt 9 on the side away from the support column 13.

[0059] like Figure 1 , 2 As shown, the protective tube 1 is nested between the upper pressing ring assembly 8 and the lower pressing ring assembly 10 .

[0060] The upper pressure ring assembly 8 of the present invention can be detached from the corresponding snap ring 17, while the lower pressure ring assembly 10 is hingedly mounted on the corresponding snap ring 17 through the pin 16, and the lower pressure ring assembly 10 cannot be detached from the corresponding snap ring 17; Fig.19 , 20 As shown, when installing the protective tube 1, the protective tube 1 is installed on the wall through the upper pressure ring assembly 8 and the lower pressure ring assembly 10. At this time, the upper pressure ring assembly 8 and the lower pressure ring assembly 10 are pressed against the protective tube 1 by the second fixing bolt 9, and the upper pressure ring assembly 8 and the lower pressure ring assembly 10 will be deformed under pressure; in this state, the third fixing bolt 12 is tightened to make the clamping plate 14 and the limiter cooperate, and the lower end of the clamping plate 14 is inserted between the limiter plate 15 and the support column 13, one side of the clamping plate 14 is close to the fixed pad 11, and the other side of the clamping plate 14 is close to the outer wall surface of the upper pressure ring assembly 8; the upper pressure ring assembly 8 is hingedly installed on the support column 13 through the clamping plate 14, the limiter plate 15, the fixed pad 11 and the corresponding clamping ring 17, and cannot be detached; as shown Fig. 22 As shown, when the third fixing bolt 12 is loosened, the upper pressure ring assembly 8 will reset from the deformed state and squeeze the clamping plate 14, so that the clamping plate 14 will be disengaged from between the limiting plate 15 and the fixed pad 11, and the limiting ability of the clamping plate 14 on the upper pressure ring assembly 8 will fail, and the upper pressure ring assembly 8 will lose the pressure on the protective tube 1. At this time, the worm wheel 29 and the worm 27 located on the lower side will release the meshing relationship and disengage, and the support structure 21 located on the lower side will swing downward under the gravity of the cable 35 to become a horizontal state; the cable 35 will be pressed on the lower side of the protective tube 1.

[0061] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.

[0062] Implementation method: When using the protective tube 1 designed by the present invention, firstly, insert the regulating ring 4 and the components installed on the regulating ring 4 into the protective tube 1, and then adjust the position of the regulating ring 4 by using the external magnet, so that one side of the slidable support 23 installed in the regulating ring 4 is located at the lower side of the regulating ring 4, and the two supporting structures 21 are distributed up and down in the regulating ring 4; when adjusting the position of the regulating ring 4, place the external magnet on the outside of the protective tube 1, observe the suction force exerted on the external magnet, and judge the position of the regulating ring 4 by the size of the suction force. When it is observed that the position of the regulating ring is not adjusted properly, the driving magnetic ring 2 can be rotated in the reverse direction. At this time, because the supporting structure on the meshing side of the worm gear and the worm is close to the inner wall surface of the regulating ring, when the driving magnetic ring rotates in the reverse direction, the supporting structure will be limited by the inner wall surface of the regulating ring and cannot swing. At this time, the reverse rotation of the driving magnetic ring will drive the transmission magnetic ring 20 to rotate, and the rotation of the transmission magnetic ring 20 will drive the transition ring 19 to rotate. The rotation of the ring 19 drives the gear ring 32 to rotate, and the rotation of the gear ring 32 drives the transmission gear 31, the worm 27, the worm wheel 29, the first rotating shaft 28 and the support structure 21 to rotate circumferentially around the axis of the regulating ring 4. During this process, the support structure on the side where the worm wheel and the worm are not engaged will swing freely with the rotation of the regulating ring, but when it is properly adjusted, the support structure will automatically fall close to the inner wall of the regulating ring under the action of its own gravity; when it is observed that the suction force on the external magnet reaches the maximum, the rotation of the driving magnetic ring 2 is stopped, and the adjustment of the regulating ring 4 is completed, and the two support structures 21 are located on the upper and lower sides of the regulating ring 4; then the pressing ring mechanism 3 is installed on the wall by the third fixing bolt 12, and the protective tube 1 is clamped between the upper pressing ring assembly 8 and the lower pressing ring assembly 10 by the second fixing bolt 9; then the cable 35 is inserted into the protective tube 1, and the inserted cable 35 can slide forward close to the support structure 21 located on the lower side, such as Fig.21 As shown, after the cable 35 is inserted, the driving magnetic ring 2 is installed on the outside of the protective tube 1, and the driving magnetic ring 2 is controlled to rotate. The driving magnetic ring 2 will drive the transmission magnetic ring 20 to rotate, and the rotation of the transmission magnetic ring 20 drives the transition ring 19 to rotate, and the rotation of the transition ring 19 drives the gear ring 32 to rotate, and the rotation of the gear ring 32 drives the transmission gear 31 to rotate, and the rotation of the transmission gear 31 drives the worm 27 to rotate, and the rotation of the worm 27 drives the worm wheel 29 meshing therewith to rotate, and the rotation of the worm wheel 29 drives the first rotating shaft 28 to rotate, and the rotation of the first rotating shaft 28 drives the corresponding supporting structure 21 to rotate, and the cable 35 is pushed upward by the ends of the two supporting structures 21 away from the first rotating shaft 28, so that the cable 35 is clamped between the two supporting structures 21, and an annular gap is formed between the cable 35 and the protective tube 1, so as to prevent the installation tool from hitting the bottom of the protective tube 1 and damaging the cable 35 in the protective tube 1 due to the damage of the bottom of the protective tube 1 when installing a new cable 35 protective tube 1.

[0063] When one of the third fixing bolts 12 becomes loose during use, the upper pressure ring assembly 8 is reset from the deformed state to squeeze the clamping plate 14, so that the clamping plate 14 is disengaged from between the limiting plate 15 and the fixed pad 11, and the clamping plate 14 loses its limiting ability on the upper pressure ring assembly 8. The upper pressure ring assembly 8 loses its pressure on the protective tube 1. At this time, the worm wheel 29 and the worm 27 on the lower side will release the meshing relationship and disengage, and the support structure 21 on the lower side will swing downward under the gravity of the cable 35 to press the protective tube; the cable 35 will be pressed on the lower side of the protective tube 1. Fig.23 As shown, in this way, the protective tube is pressed by the contact surface of the longer length of the protective tube, which can better protect the protective tube compared to the local pressure exerted by the cable directly squeezing the card support structure that loses the wall support function and then presses on the protective tube.
