The following will be explained in conjunction with Figures 1 to 5 for explanation.

[0027] Some of the specific implementation manners described below are intended to facilitate those skilled in the art to understand the present embodiment, and the present embodiment is not limited to some of the specific implementation manners described below.

[0028] Refer to Figure 1 and Figure 2, A guiding double - helix cable protective sleeve provided by an exemplary embodiment of the present disclosure, the guiding double - helix cable protective sleeve includes:

[0029] A protective sleeve 1, including at least two groups of protective belts 12 that are in reverse spiral shapes and cross - distributed. Between the protective belts 12 in the same group, they are parallel and spaced apart. A threading channel 11 for the cable to pass through is formed inside the protective sleeve 1, and the threading channel 11 communicates with the outside from one side of the protective belt 12.

[0030] A bracket 2, fixed to the protective belt 12 and having a fixing member 23 for fixing the bracket 2 to an external foundation.

[0031] Exemplarily, referring to Figure 1 and Figure 2 , there are two groups of protective belts 12, namely group a and group b. Each group of protective belts 12 has two pieces. The two pieces in the same group are coaxially arranged in a spiral - twisted manner. The twisting directions of the two groups of protective belts 12 are opposite, and the two groups of protective belts 12 are staggered. For example, when observing along the length direction of the protective belt 12, one protective belt 12 in group a bypasses the bottom surface of the c protective belt 12 in group b and then winds out from the top surface of the d protective belt 12 in group b, and after passing through the top surface of the protective belt 12 in this group b, it continues to wind in a spiral shape around the bottom surface of the d protective belt 12 in this group b. Each protective belt 12 in each group is wound in this way. That is, on the same protective belt 12, for the overlapping parts of this protective belt 12 and other protective belts 12 distributed in sequence along the length direction of this protective belt 12, this protective belt 12 is arranged in the form of being on the top (or outside), on the bottom (or inside), on the top (or outside)... The two groups of stacked and intertwined protective belts 12 form a tubular cage - shaped protective sleeve 1 with both ends open. The threading channel 11 is formed in the internal hollow area of the protective sleeve 1, and the two ends of the threading channel 11 are open for the cable to extend in and out. The outer wall of the protective sleeve 1 is a continuous but non - airtight structure. There are multiple openings formed between the edges of different protective belts 12 on the outer wall of the protective sleeve 1, and the threading channel 11 also communicates with the outside through these openings. The brackets 2 are fixed to the outer wall of the protective sleeve 1 and are arranged in multiple numbers along the length direction of the protective sleeve 1. Part of the outer wall of the bracket 2 is simultaneously fixed to multiple protective belts 12 and is distributed on the same side of the protective sleeve 1. The fixing member 23 penetrates the bracket 2 in a direction perpendicular to the threading channel 11 and is used to fix the bracket 2 to an external foundation such as a wall.

[0032] In this embodiment, multiple groups of overlapping points of the protective bands 12 are formed on the outer wall of the protective sleeve 1 at intervals by at least two groups of protective bands 12 that are spirally opposed and cross-distributed. Each group of overlapping points is relatively distributed on two opposite sides of the protective sleeve 1, and there is at least another group of overlapping points with a different position (relative to the upper and lower sides of the threading channel 11) between each two adjacent groups of overlapping points located on the same side of the protective sleeve 1 (relative to the left and right sides of the threading channel 11). This significantly improves the compression and bending resistance of the protective sleeve 1 and can provide stable and effective protection for the cable.

[0033] In an exemplary embodiment of the present disclosure, referring to Figure 1 and Figure 3 The bracket 2 includes a positioning ring 21 buckled on the side wall of the protective sleeve 1, and a support leg 22 fixed to the positioning ring 21. The end of the support leg 22 extends out of the protective sleeve 1, and the fixing member 23 is fixed to the end of the support leg 22.

[0034] For example, refer to Figure 1 and Figure 3 The positioning ring 21 is fixed to the two protective belts 12 belonging to different groups at the same time. The positioning ring 21 is a semicircular ring structure buckled at the overlapping position of the two protective belts 12. The support leg 22 is T-shaped and integrally formed on the arc-shaped outer wall of the positioning ring 21. One end of the support leg 22 is fixed to the positioning ring 21, and the other two ends extend from the opposite sides of the protective cover 1 respectively. The fixing member 23 extends from the end of the support leg 22 outside the protective cover 1 and passes through the support leg 22. For example, the fixing member 23 is a screw, and the head of the screw is located on the side of the support leg 22 facing the positioning ring 21, and the threaded tail end of the screw extends from the side of the support leg 22 away from the positioning ring 21.

[0035] In this embodiment, the semicircular positioning ring 21 can provide stable and effective support and positioning for the protective cover 1 under the premise of reducing its own weight, and the positioning ring 21 is fixed at the intersection of the two protective belts 12 belonging to different groups, which can form a strong connection strength with the protective cover 1, reducing the possibility of the protective cover 1 falling off the positioning ring 21; the supporting legs 22 extending from both sides of the protective cover 1 and with fixings 23 can fix the protective cover 1 to the wall or the ground, so that the cable passing through the protective cover 1 can be limited to a predetermined position. At the same time, since the end of the supporting legs 22 extends outside the protective cover 1, the process of applying force to the fixings 23 to fix it to the external foundation will not be interfered with by the physical structure of the protective cover 1, which facilitates the disassembly and assembly of the protective cover 1.

[0036] In an exemplary embodiment of the present disclosure, referring to Figure 3 and Figure 4 The inner wall of the positioning ring 21 has claws 3 for clamping the protective strip 12.

[0037] For example, refer to Figure 3 and Figure 4, the clamping jaw 3 is fixed on the inner arc-shaped side wall of the positioning ring 21. One end of the clamping jaw 3 is fixed to the inner arc-shaped side wall of the positioning ring 21, and the other end extends along the inner arc-shaped side wall of the positioning ring 21, forming a gap for accommodating the protective belt 12 between it and the inner wall of the positioning ring 21. The openings of the clamping jaws 3 on two adjacent positioning rings 21 are arranged oppositely.

[0038] In this embodiment, by placing the protective sleeve 1 inside the positioning ring 21 and moving or squeezing or rotating the protective sleeve 1, the overlapping position of the two protective belts 12 belonging to two groups enters the gap between the clamping jaw 3 and the inner arc-shaped side wall of the positioning ring 21, which can reduce the possibility of the protective sleeve 1 disengaging from inside the positioning ring 21. At the same time, the openings of the clamping jaws 3 on two adjacent positioning rings 21 are arranged oppositely, which further improves the fixing effect of the clamping jaws 3 on the protective sleeve 1. That is, after inserting part of the protective sleeve 1 into the clamping jaw 3 on one positioning ring 21, by moving or squeezing or rotating the protective sleeve 1, the overlapping position of the two protective belts 12 belonging to two groups on the other part of the protective sleeve 1 enters the gap between the other clamping jaw 3 and the inner arc-shaped side wall of the positioning ring 21, which can apply a limit in another direction to the protective sleeve 1 and further reduce the possibility of the protective sleeve 1 disengaging from inside the positioning ring 21.

[0039] In an exemplary embodiment of the present disclosure, referring to Figure 3 and Figure 4 , the clamping jaw 3 includes a clamping plate 31 integrally formed on the inner wall of the positioning ring 21 and forming a gap with the inner wall of the positioning ring 21, and a clamping block 32 integrally formed with the clamping plate 31 and extending towards the inner wall of the positioning ring 21.

[0040] Exemplarily, referring to Figure 3 and Figure 4 , the clamping plate 31 is arc-shaped and adapted to the inner arc-shaped side wall of the positioning ring 21. One end of the clamping plate 31 is integrally formed on one side of the inner arc-shaped side wall of the positioning ring 21, the other end of the clamping plate 31 extends towards the other side and warps up. The clamping block 32 is fixed to the side wall of the warped end of the clamping plate 31 facing the inner arc-shaped side wall of the positioning ring 21, and the clamping block 32 abuts against the inner arc-shaped side wall of the positioning ring 21.

[0041] In this embodiment, the clamping block 32 is semi-cylindrical with its axis parallel to the axis of the protective sleeve 1, and the outer wall of the clamping block 32 facing the inner arc-shaped side wall of the positioning ring 21 is a cylindrical surface. By moving or squeezing or rotating the protective sleeve 1, the edge of the protective belt 12 abuts against the arc-shaped outer wall of the clamping block 32, and through further moving or squeezing or rotating, it passes through the clamping block 32 and enters between the clamping plate 31 and the inner arc-shaped side wall of the positioning ring 21. At this time, the clamping block 32 abuts against the inner arc-shaped side wall of the positioning ring 21 again. Through the clamping block 32, the possibility of the protective belt 12 disengaging from between the clamping plate 31 and the inner arc-shaped side wall of the positioning ring 21 can be reduced, and the connection strength between the positioning ring 21 and the protective sleeve 1 is improved.

[0042] In an exemplary embodiment of the present disclosure, with reference to Figure 1 and Figure 3 , the inner wall of the positioning ring 21 has a positioning groove 24 adapted to the protective belt 12, and the claw 3 straddles above the positioning groove 24.

[0043] Exemplarily, with reference to Figure 3 and Figure 4 , the positioning groove 24 has a cross structure adapted to the overlapping position shape of two protective belts 12 belonging to two groups. The positioning groove 24 extends from the inner arc side wall of the positioning ring 21 to the solid interior of the positioning ring 21. One end of the claw 3 is fixed on the inner arc side wall of the positioning ring 21 on one side of the positioning groove 24, and the other end of the claw 3 straddles the positioning groove 24 in a direction perpendicular to the threading channel 11 and extends to the other side of the positioning groove 24.

[0044] In this embodiment, the positioning groove 24 is used to accommodate the overlapping position of two protective belts 12 belonging to two groups, and the side walls of part of the protective belt 12 are exposed from the top opening of the positioning groove 24, that is, the depth of the positioning groove 24 is less than the thickness of the overlapping position of two protective belts 12 belonging to two groups. When two protective belts 12 belonging to two groups are formed into a structure with the same thickness as the protective belt 12 by hot melting, the depth of the positioning groove 24 is less than the thickness of the protective belt 12. Similarly, when the overlapping position of two protective belts 12 belonging to two groups is fixed by bonding or riveting, or even has no fixed connection relationship, the depth of the positioning groove 24 is greater than the thickness of the protective belt 12 and less than twice the thickness of the protective belt 12. The positioning groove 24 can apply multi-directional limits to the overlapping position of two protective belts 12 belonging to two groups. Combining with the vertical limit applied by the claw 3 straddling above the positioning groove 24 to the overlapping position of two protective belts 12 belonging to two groups, the protective sleeve 1 can be more stably connected to the positioning ring 21 and the disassembly and assembly process of the protective sleeve 1 on the positioning ring 21 can be reduced.

[0045] In an exemplary embodiment of the present disclosure, with reference to Figure 2 and Figure 5 , the included angle between the partial inner wall of the protective belt 12 and the axis of the protective sleeve 1 is set, and a plurality of reduced-diameter sections 14 are formed inside the threading channel 11.

[0046] Exemplarily, with reference to Figure 2 and Figure 5, the included angle between the inner wall of the overlapping position of the two protective belts 12 belonging to two groups and the axis of the protective sleeve 1 is set. The overlapping position of the two protective belts 12 belonging to two groups deflects towards the inside of the threading channel 11 at one end in the length direction of the threading channel 11. Since the overlapping positions of the two protective belts 12 belonging to two groups are symmetrically distributed with respect to the axis of the threading channel 11, the reduced-diameter section 14 is formed between the overlapping positions of the two protective belts 12 belonging to two groups distributed on the opposite sides of the threading channel 11. Similarly, the inner wall with the included angle between the protective belt 12 and the axis of the protective sleeve 1 forms an enlarged-diameter section 13 inside the threading channel 11, and the enlarged-diameter section 13 and the reduced-diameter section 14 are distributed at intervals along the length direction of the threading channel 11.

[0047] In this embodiment, the reduced-diameter section 14 can exert a limiting and anti-retreat effect on the cable extending into the inside of the threading channel 11, reducing the possibility of the cable inside the threading channel 11 being displaced relative to the protective sleeve 1 under external force. At the same time, the enlarged-diameter section 13 adapted to the reduced-diameter section 14 can facilitate the cable to enter the inside of the threading channel 11 and exert a guiding effect on the cable for entering and passing through the reduced-diameter section 14.

[0048] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
