The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0033] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0034] See also Figures 1 to 3 The present embodiment provides a protective device 100, comprising a first protective member 10, a second protective member 20 and a plurality of partitioning components 30. The first protective member 10 is provided with a first mounting hole K1, and the first mounting hole K1 is used to accommodate a cable 201. The second protective member 20 is sleeved on the outer peripheral side of the first protective member 10, and an annular receiving space Q1 is defined between the inner surface of the second protective member 20 and the outer peripheral surface of the first protective member 10. The plurality of partitioning components 30 are distributed at intervals along the circumference of the receiving space Q1, and the plurality of partitioning components 30 divide the receiving space Q1 into a plurality of chambers Q11, and the plurality of chambers Q11 are used to fill the protective material 40, and both ends of the plurality of partitioning components 30 abut against the first protective member 10 and the second protective member 20. Among them, the second protective member 20 includes multiple protective segments 21, and the multiple protective segments 21 are connected end to end in sequence. The two ends of each protective segment 21 are respectively provided with a plug-in groove C5 and a plug-in portion 23. The plug-in portion 23 at one end of the protective segment 21 can be movably engaged in the plug-in groove C5 of the protective segment 21 adjacent to the protective segment 21, so that the second protective member 20 can expand outward or shrink inward relative to the first protective member 10, thereby adjusting the cross-sectional area of ​​the chamber Q11.

[0035] According to the protective device 100 of this embodiment, the matching state between each adjacent two protective segments 21 can be adjusted according to the actual installation environment of the cable 201 and the actual installation requirements, so that the second protective member 20 is expanded or contracted relative to the first protective member 10, thereby adjusting the overall cross-sectional area of ​​the receiving space Q1, and then adjusting the cross-sectional area of ​​multiple chambers Q11, so as to fill the corresponding protective material 40 in different chambers Q11, thereby improving the versatility of the protective device 100. According to the different installation environments of the cable 201, the corresponding protective effects required in different circumferential areas of the cable 201 are also different. The protective device 100 of the present application can also adjust the cross-sectional area of ​​the chamber Q11 on one side thereof to achieve the effect of maximizing the protective effect. In addition, different cables 201 can also be installed in each chamber Q11, so as to realize the parallel placement of multiple cables 201, thereby improving the space utilization rate of the protective device 100. In this way, compared with the known cable 201 integrated with the protective material 40, the protective device 100 of the present application can improve the versatility of protection and meet the reliable protection of multiple cables 201 at the same time.

[0036] In addition, in this embodiment, the shape of the first protective member 10 remains fixed, which can facilitate improving the installation stability of the cable 201 in the first installation hole K1.

[0037] In some embodiments, see Figure 3The protection section 21 further includes a first stopper 22. The first stopper 22 is convexly disposed on the side of the insertion slot C5, and the first stopper 22 defines the first through hole K6. The plug-in portion 23 includes a first sliding section 231 and a first limit block 232. The first sliding section 231 connects the first limit block 232 and the protection section 21. The first sliding section 231 is movably disposed in the first through hole K6. The first limit block 232 is located in the insertion slot C5. The cross-sectional area of ​​the first limit block 232 is larger than the cross-sectional area of ​​the first through hole K6, so as to prevent the plug-in portion 23 from escaping from the insertion slot C5.

[0038] In some embodiments, see Figure 2 and Figure 3 The protective device 100 also includes a plurality of first elastic members 24, one of which is provided between each two adjacent protective segments 21, and the first elastic member 24 is elastically supported between the bottom surface of the insertion slot C5 and the insertion portion 23. The first elastic member 24 can drive the two adjacent protective segments 21 to approach each other during the shrinking process of the chamber Q11, thereby realizing the inward shrinkage of the second protective member 20 relative to the first protective member 10. At the same time, during the outward expansion process of the second protective member 20 relative to the first protective member 10, the first elastic member 24 can play a buffering role. The first elastic member 24 can be specifically set as a spring or an elastic column.

[0039] In some embodiments, the protection device 100 may include a plurality of first protection members 10 and a plurality of second protection members 20, which are arranged radially staggered and define a plurality of receiving spaces Q1 arranged radially at intervals. In this way, the number of chambers Q11 can be further increased, and the protection reliability can be further improved.

[0040] In some embodiments, the second protection member 20 defines a second mounting hole K2. The first protection member 10 is received in the second mounting hole K2, and a receiving space Q1 is formed between the first protection member 10 and the hole surface of the second mounting hole K2.

[0041] In some embodiments, see Figure 4 , the second protective member 20 is provided with a plurality of injection holes K3. The plurality of injection holes K3 are sequentially spaced along the circumference of the protective device 100, and an injection hole K3 is provided between each two adjacent partition components 30. The injection hole K3 can be used for injecting the protective material 40 from the external environment of the protective device 100 into the chamber Q11. Among them, the protective material 40 can be a gel material or a liquid material that can be solidified. The protective material 40 can be set as a material with different functions such as flame retardant function, rodent-proof function, fire-resistant function, waterproof function, etc. For example, the protective material 40 can be a variety of materials such as a capsaicin microcapsule filling strip, a flame-retardant aqueous gel, or a semi-solid ceramic liquid silicone rubber.

[0042] In other embodiments, two or more injection holes K3 may be disposed between every two adjacent partition assemblies 30 .

[0043] In some embodiments, see Figure 4 The protective device 100 further includes a plurality of one-way valves 70. The number of the one-way valves 70 is the same as the number of the injection holes K3. A one-way valve 70 is installed in each injection hole K3. The one-way valve 70 allows the protective material 40 to be injected into the chamber Q11 and blocks the protective material 40 from being discharged from the chamber Q11, so that it is not necessary to close the injection hole K3 after the protective material 40 is filled, thereby improving the convenience of use of the protective device 100.

[0044] In the present embodiment, the cross section of the accommodation space Q1 is annular, and each chamber Q11 has an inner surface formed by a portion of the first protection member 10 and an outer surface formed by a portion of the second protection member 20 .

[0045] In some embodiments, see Figure 4 One end of each partition assembly 30 can move along the circumference of the first protective member 10, and the other end of each partition assembly 30 can move along the circumference of the second protective member 20 to adjust the cross-sectional area of ​​the chamber Q11. In this way, the dimensions of the chamber Q11 along the circumference and radial directions of the protective device 100 can be adjusted, thereby further improving the adjustment versatility of the protective device 100.

[0046] In some embodiments, see Figure 4 A plurality of first limiting grooves C1 are provided on the outer peripheral surface of the first protective member 10. The plurality of first limiting grooves C1 are arranged at intervals along the circumference of the first protective member 10. The extension direction of the plurality of first limiting grooves C1 is parallel to the extension direction of the first protective member 10. A partition component 30 is correspondingly arranged in each first limiting groove C1.

[0047] In this way, the first limiting groove C1 can limit the circumferential movement of the partition component 30 to ensure the maximum and minimum circumferential spacing between the two partition components 30 corresponding to the two adjacent first limiting grooves C1, thereby controlling the maximum and minimum cross-sectional areas of the chamber Q11 formed between the two adjacent partition components 30.

[0048] In some embodiments, see Figure 4 The inner circumferential surface of the second protective member 20 is provided with a plurality of second limiting grooves C2, and the plurality of second limiting grooves C2 are arranged at intervals along the circumference of the second protective member 20. The extension direction of the plurality of second limiting grooves C2 is parallel to the extension direction of the second protective member 20, and a partition component 30 is correspondingly arranged in each second limiting groove C2.

[0049] In this way, the second limiting groove C2 can limit the circumferential movement of the partition component 30 to ensure the maximum and minimum circumferential spacing between the two partition components 30 corresponding to the two adjacent second limiting grooves C2, thereby controlling the maximum and minimum cross-sectional areas of the chamber Q11 formed between the two adjacent partition components 30.

[0050] In this embodiment, the plurality of first limiting grooves C1 are evenly spaced along the circumferential direction, and the plurality of second limiting grooves C2 are evenly spaced along the circumferential direction. The number of the first limiting grooves C1 is the same as the number of the second limiting grooves C2. Along the radial direction of the protective device 100, the plurality of first limiting grooves C1 are arranged one by one corresponding to the plurality of second limiting grooves C2.

[0051] In some embodiments, see Figure 4 The protection device 100 further includes an outer protection member 60. The outer protection member 60 is coated on the outer peripheral surface of the second protection member 20 to seal the injection hole K3 and further improve the protection effect of the protection device 100.

[0052] In some embodiments, see Figure 5 The partition assembly 30 includes a first end 361 and a second end 362 that are arranged opposite to each other. The first end 361 is in one-way transmission cooperation with the outer circumference of the first protective member 10. When the partition assembly 30 is subjected to a positive force along the circumference of the protective device 100, the first end 361 moves along the outer circumference of the first protective member 10. When the partition assembly 30 is subjected to a reverse force along the circumference, the first end 361 is locked relative to the first protective member 10. The second end 362 is in one-way transmission cooperation with the inner circumference of the second protective member 20. When the partition assembly 30 is subjected to a reverse force along the circumference, the second end 362 moves along the inner circumference of the second protective member 20. When the partition assembly 30 is subjected to a positive force along the circumference, the second end 362 is locked relative to the second protective member 20. The positive direction is the clockwise direction of the circumference, and the reverse direction is the counterclockwise direction of the circumference.

[0053] In this way, in the process of injecting protective material into the chamber Q11 between two adjacent partition components 30, the second end 362 of the partition component 30 on the positive side of the circumference is locked, and the first end 361 can move in the positive direction of the circumference; the first end 361 of the partition component 30 on the other side of the positive direction of the circumference is locked, and the second end 362 can move in the reverse direction of the circumference. After the capacity of the injected protective material reaches the preset value, the injection of the protective material can be stopped. In addition, since the two partition components 30 are locked relative to the first protective member 10 and the second protective member 20 respectively, in the process of injecting other protective materials into the chamber Q11 on the other side of the chamber Q11, the injection of the previous chamber Q11 will not be affected, thereby ensuring the injection reliability of the protective material of each chamber Q11. In this way, the protective device of this embodiment can be injected with protective material after the protective device is at the construction site, without the need to fill the protective material during the assembly process, further improving the versatility of the protective device.

[0054] In addition, since at least one of the first end 361 and the second end 362 is locked, the possibility of the partition assembly 30 being separated from the first protective member 10 or the second protective member 20 can be reduced, thereby improving the application reliability of the protective device 100.

[0055] In some embodiments, see Figure 5 A plurality of first ratchet teeth 81 are provided on the outer peripheral side of the first protective member 10, and the extension direction of the plurality of second ratchet teeth 82 extends from the radial direction of the second protective member 20 to the positive direction of the circumferential direction, and a first tooth groove C7 is formed between each two adjacent first ratchet teeth 81. The first end portion 361 extends into the first tooth groove C7. A plurality of second ratchet teeth 82 are provided on the inner surface of the second protective member 20, and the extension direction of the plurality of second ratchet teeth 82 extends from the radial direction of the second protective member 20 to the negative direction of the circumferential direction, and a second tooth groove C8 is formed between each two adjacent second ratchet teeth 82. The second end portion 362 extends into the second tooth groove C8. In this way, the first end portion 361 can freely move in the positive direction and be locked in the reverse direction, and the second end portion 362 can be locked in the positive direction and freely move in the positive direction.

[0056] In some embodiments, see Figure 5 The bottom surface of each first limiting groove C1 is provided with a plurality of first ratchet teeth 81 in one-to-one correspondence. The bottom surface of each second limiting groove C2 is provided with a plurality of second ratchet teeth 82 in one-to-one correspondence.

[0057] In some embodiments, see Figure 6 and Figure 7, the partition assembly 30 includes a first partition segment 31 and a second partition segment 32. One end of the first partition segment 31 abuts against the first protective member 10. One end of the second partition segment 32 is slidably connected to the first partition segment 31, and the other end of the second partition segment 32 is connected to the protective segment 21. The second partition segment 32 can move closer to or farther from the first protective member 10 driven by the protective segment 21. In this way, when the protective material 40 is injected into the chamber Q11 and the partition assembly 30 is pushed to move in the circumferential direction, the partition assembly 30 is tilted, and the second partition segment 32 slides relative to the first partition segment 31, so that the partition assembly 30 can be extended or shortened, thereby adapting to the changes in the chamber Q11 and ensuring the reliability of the closure of the chamber Q11.

[0058] In some embodiments, see Figure 7 , a second slot C3 is provided at one end of the second partition section 32 facing the first protection member 10, and a second stopper 33 is convexly provided on the inner surface of the second slot C3. The first partition section 31 extends into the second slot C3 at one end facing the second protection member 20, and a second limiting portion 34 is provided at the portion of the first partition section 31 extending into the second slot C3, and the second limiting portion 34 is blocked by the second stopper 33 to limit the first partition section 31 from escaping from the slot. In this way, the second limiting portion 34 can slide along the length direction of the second slot C3, so that the first partition section 31 can slide relative to the second partition section 32. The second stopper 33 can limit the second limiting portion 34 from escaping from the second through hole K4, thereby ensuring a reliable connection between the first partition section 31 and the second partition section 32.

[0059] In some embodiments, see Figure 6 and Figure 7 The partition assembly 30 further includes a second elastic member 35. The second elastic member 35 is elastically supported between the bottom surface of the second chute C3 and the second stopper 34. The second elastic member 35 can drive the first partition section 31 to move closer to the second partition section 32 during the shrinking process of the chamber Q11, thereby realizing the automatic return of the length of the partition assembly 30. At the same time, the second elastic member 35 can play a buffering role during the extension process of the partition assembly 30.

[0060] In other embodiments, the second elastic member 35 may also be sleeved on the first partition segment 31 and abutted between the second partition segment 32 and the first protective member 10 .

[0061] In other embodiments, see Figure 8 and Fig. 9 The partition assembly 30 includes an elastic portion 37 and a connecting portion 38. The elastic portion 37 elastically abuts against the first protection member 10. The connecting portion 38 abuts against the second protection member 20. The connecting portion 38 connects the elastic portion 37.

[0062] In this way, during the process of filling the protective material 40, when the partition component 30 is subjected to uneven force from the protective material 40 at various locations along the radial direction, the extension direction of the partition component 30 deviates from the radial direction of the protective device 100, and the first elastic part 37 and the second elastic part 37 can produce elastic deformation to adapt to the deviation of the partition component 30, and ensure that the partition component is reliably connected between the first protective member 10 and the second protective member 20, thereby ensuring the airtightness of each chamber Q11.

[0063] The elastic portion 37 may be constructed as an elastic column or other structure that can achieve a separation and sealing function.

[0064] In some embodiments, the elastic portion 37 abuts against the bottom surface of the first limiting groove C1 , and the connecting portion 38 abuts against the bottom surface of the second limiting groove C2 .

[0065] In some embodiments, see Fig.10 and Fig.11 The protective device 100 also includes a plurality of limiter assemblies 50, and a limiter assemblies 50 is correspondingly arranged between each two adjacent partition assemblies 30, and the plurality of limiter assemblies 50 are respectively and one by one correspondingly and telescopically connected to the plurality of adjacent two partition assemblies 30. In this way, when the cross-sectional area of ​​the chamber Q11 is expanded or reduced, the protective segment 21 drives the partition assemblies 30 to move radially, and the limiter assemblies 50 can be extended and retracted to adapt to the movement of the partition assemblies 30, thereby reducing the possibility of the partition assemblies 30 getting stuck and ensuring the smooth adjustment of the cross-sectional area of ​​the chamber Q11. In addition, the limiter assemblies 50 can also play a buffering and guiding role in the movement of the two adjacent partition assemblies 30 to approach or move away, so as to improve the movement reliability of the partition assemblies 30.

[0066] In some embodiments, a plurality of partition components 30 are disposed between every two adjacent partition components 30 , and the plurality of partition components 30 are distributed at intervals along the radial direction.

[0067] In some embodiments, see Fig.10 and Fig.11 The limiting assembly 50 includes a first limiting section 51 and a second limiting section 52. The first limiting section 51 is connected to one of the two adjacent partitioning assemblies 30, and the second limiting section 52 is connected to the other of the two adjacent partitioning assemblies 30. The first limiting section 51 is provided with a third slide groove C4 at one end thereof facing the second limiting section 52, and the second limiting section 52 is slidably fitted in the third slide groove C4 at one end thereof close to the first limiting section 51. In this way, the second limiting section 52 can slide along the length direction of the third slide groove C4, so that the first limiting section 51 can slide relative to the second limiting section 52.

[0068] In some embodiments, see Fig.11, a third stopper 53 is convexly provided on the inner surface of the third slide groove C4, and the third stopper 53 defines the third through hole K5. The second limiting section 52 extends into the third slide groove C4 toward one end of the second limiting section 52. The limiting assembly 50 also includes a third limiting section 54. The third limiting section 54 is connected to one end of the first limiting section 51 extending into the third slide groove C4.
