Description

Technical Field

[0001] This invention relates to the field of cable protection technology, and in particular to a cable protection device. Background Technology

[0002] Cables are a general term for items such as optical cables and electrical cables. Cables have many uses, mainly for control installation, connection settings, and power transmission. They are one of the indispensable items in people's daily life and work.

[0003] Cables typically require external protective devices during use to prevent damage and ensure proper functioning. Cables are prone to bending, and in severe cases, breakage. However, most current cable protection devices only provide sealing protection and are insufficient to prevent bending and breakage, thus reducing their effectiveness.

[0004] Therefore, how to protect cables from bending and breakage has become an urgent problem to be solved. Summary of the Invention

[0005] This invention provides a cable protection device to solve the problem that existing cable protection devices are unable to protect cables from bending and breakage.

[0006] This invention provides a cable protection device, comprising multiple protective sleeves connected end-to-end;

[0007] The protective sleeve includes a main body and a first connecting part and a second connecting part located at both ends of the main body;

[0008] The inner wall of the first connecting part has a snap-fit ​​element, and the outer periphery of the second connecting part has a snap-fit ​​groove that mates with the snap-fit ​​element. The snap-fit ​​element on the protective sleeve is engaged in the snap-fit ​​groove on the adjacent protective sleeve.

[0009] The snap-fit ​​component and the snap-fit ​​groove are fitted with a clearance, allowing for a limited range of swing between two adjacent protective sleeves.

[0010] In one possible implementation, the snap-fit ​​member includes a first snap-fit ​​portion and a second snap-fit ​​portion distributed axially along the first connection portion;

[0011] The snap-fit ​​groove includes a first snap-fit ​​groove and a second snap-fit ​​groove distributed along the axial direction of the second connecting part.

[0012] The first snap-fit ​​part is snapped into the first snap-fit ​​groove, and the second snap-fit ​​part is snapped into the second snap-fit ​​groove;

[0013] The first snap-fit ​​portion is retractably disposed on the inner wall of the first connecting portion.

[0014] In one possible implementation, the inner wall of the first connecting portion is provided with a first mounting groove, and the first snap-fit ​​portion is at least partially located in the first mounting groove.

[0015] The protective sleeve also includes an adjusting rod, which includes an operating section and a connecting section connected together, and the side of the first snap-fit ​​portion facing the first assembly groove has a threaded hole;

[0016] The operating section extends outward from the outside of the first connecting portion;

[0017] The outer periphery of the connecting section has external threads. The connecting section is located in the first assembly groove and mates with the threaded hole. The connecting section adjusts the assembly length of the first connecting part in the first assembly groove by mates with the threaded hole.

[0018] In one possible implementation, a limiting disk is also provided between the operating segment and the connecting segment;

[0019] The first connecting part also has a limiting groove that cooperates with the limiting plate, and the limiting groove is connected to the first assembly groove, and the limiting plate is locked in the limiting groove.

[0020] In one possible implementation, the protective sleeve includes a first protective portion and a second protective portion that are disposed opposite to and connected to each other;

[0021] One end of the first protective part and one end of the second protective part are rotatably connected by a hinge. The outer wall of the other end of the first protective part has a first locking member, and the outer wall of the other end of the second connecting part has a second locking member that matches the first locking member. The other ends of the first protective part and the second protective part are detachably connected by the cooperation of the first locking member and the second locking member.

[0022] In one possible implementation, the first protective part has a first engaging portion on the mating surface facing the second protective part;

[0023] The second connecting part has a second engaging part on the mating surface facing the first protective part, which cooperates with the first engaging part;

[0024] The first engaging part engages with the second engaging part.

[0025] In one possible implementation, the bottom walls of the first card slot and the second card slot are respectively provided with a first magnetic block and a second magnetic block;

[0026] The first snap-fit ​​portion has a third magnetic block with a magnetic field opposite to that of the first magnetic block at its end, and the second snap-fit ​​portion has a fourth magnetic block with a magnetic field opposite to that of the second magnetic block at its end.

[0027] In one possible implementation, a retaining sleeve is also included, the retaining sleeve being located at the end of the cable protection device and connected to the first connecting portion at the end of the cable protection device;

[0028] The inner wall of the fixing sleeve has a retaining plate, which abuts against the cable inside the cable protection device to fix the position of the cable inside the cable protection device.

[0029] One possible implementation also includes a gear shaft;

[0030] The fixed sleeve has a mounting hole, and there are mounting seats on both sides of the mounting hole. The mounting seats have a second assembly groove, and the gear shaft is rotatably disposed in the second assembly groove.

[0031] The card plate is located on the gear shaft.

[0032] In one possible implementation, the inner wall of the mounting hole has a fixed tooth that meshes with the gear shaft, the fixed tooth being engaged in one of the tooth grooves of the gear shaft;

[0033] The second assembly slot also contains a spring element, which is located on the gear shaft on the side opposite to the fixed tooth.

[0034] The above-described configuration allows the entire cable protection device to bend, enabling the cable within it to bend as needed during use. The interlocking relationship between the clips and the slots provides a limit to the swing between adjacent protective sleeves, restricting the swing amplitude within a certain range. This, in turn, limits the bending range of the entire cable protection device. This effectively prevents excessive bending of the cable within the protection device, thus preventing damage or breakage due to excessive bending and significantly improving the cable protection performance.

[0064] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0065] As described in the background section, cables inevitably bend during use. Excessive bending can shorten the cable's lifespan and, in severe cases, cause it to break. However, current cable protection devices typically only provide sealing protection, preventing water and dirt from entering the cable. They often fail to prevent bending, thus reducing the overall protective performance.

[0066] To address the aforementioned issues, researchers improved the cable protection device by incorporating multiple end-to-end protective sleeves. These sleeves allow for a limited range of oscillation between adjacent sleeves, enabling the cable within the protection device to bend within a limited range without excessive bending. This effectively reduces or prevents significant bending, thus preventing damage or breakage due to excessive bending. This contributes to improved cable stability and extended cable lifespan.

[0067] Figure 1 This is a schematic diagram of the structure of a cable protection device provided in an embodiment of this application. Figure 2 This is a schematic diagram of the structure of a protective sleeve provided in an embodiment of this application. Figure 3 This is a schematic diagram of the structure of a protective sleeve in another state, as provided in an embodiment of this application.

[0068] See Figure 1 As shown, this application embodiment provides a cable protection device 100, which can be sleeved on the outer periphery of a cable to protect it. The cable protection device 100 may include multiple protective sleeves 110 connected end-to-end. For example, the number of protective sleeves 110 can be changed according to the required cable length, thereby changing the length of the cable protection device 100, so that the cable protection device 100 can meet the protection needs of cables of different lengths.

[0069] The protective sleeve 110 may include a main body 111 and a first connecting portion 112 and a second connecting portion 113 located at both ends of the main body 111. The first connecting portion 112 on the protective sleeve 110 may be connected to the second connecting portion 113 on an adjacent protective sleeve 110 to achieve the connection of two adjacent protective sleeves 110.

[0070] Combination Figure 2 and Figure 3 As shown, the inner wall of the first connecting portion 112 may have a snap-fit ​​member 1121, and the outer periphery of the second connecting portion 113 is provided with a snap-fit ​​groove 1131 that mates with the snap-fit ​​member 1121. The snap-fit ​​member 1121 on the protective sleeve 110 can be snapped into the snap-fit ​​groove 1131 on the adjacent protective sleeve 110, so that the two adjacent protective sleeves 110 can be connected by the engagement of the snap-fit ​​member 1121 and the snap-fit ​​groove 1131. For example, during the connection of the two adjacent protective sleeves 110, the second connecting portion 113 of one protective sleeve 110 can be inserted into the first connecting portion 112 of the other protective sleeve 110, so that the snap-fit ​​member 1121 on the inner wall of the first connecting portion 112 can be snapped into the snap-fit ​​groove 1131 on the outer periphery of the second connecting portion 113, thereby realizing the connection of the two protective sleeves 110.

[0071] The snap-fit ​​component 1121 and the snap-fit ​​groove 1131 can have a clearance fit, allowing for a limited range of oscillation between adjacent protective sleeves 110. That is, when connecting two protective sleeves 110, the connection is relatively flexible, with a looser fit between the snap-fit ​​component 1121 and the snap-fit ​​groove 1131 rather than a locked state. This allows the entire cable protection device 100 to bend, and the cable within the cable protection device 100 to bend, meeting the bending requirements of the cable during use. The snap-fit ​​relationship between the snap-fit ​​component 1121 and the snap-fit ​​groove 1131 provides a certain limit to the oscillation between adjacent protective sleeves 110, restricting the oscillation amplitude between adjacent protective sleeves 110 within a certain range, thereby limiting the bending degree of the entire cable protection device 100 within a certain range. It can prevent the cable protection device 100 from bending too much, effectively preventing the cable located in the cable protection device 100 from bending too much, preventing the cable from being damaged or broken due to excessive bending, and effectively improving the protection performance of the cable protection device 100 for the cable.

[0072] See also Figure 3 As shown, the snap-fit ​​member 1121 may include a first snap-fit ​​portion 11211 and a second snap-fit ​​portion 11212 distributed axially along the first connecting portion 112, and the snap-fit ​​groove 1131 may include a first snap-fit ​​groove 11311 and a second snap-fit ​​groove 11312 distributed axially along the second connecting portion 113. The first snap-fit ​​portion 11211 can be snapped into the first snap-fit ​​groove 11311, and the second snap-fit ​​portion 11212 can be snapped into the second snap-fit ​​groove 11312. The first snap-fit ​​portion 11211 is telescopically mounted on the inner wall of the first connecting portion 112.

[0073] When two adjacent protective sleeves 110 are connected, the first snap-fit ​​portion 11211 on the first connecting portion 112 can be retracted into the inner wall of the first connecting portion 112. At this time, the second connecting portion 113 on the other protective sleeve 110 can be inserted into the first connecting portion 112 of the protective sleeve 110, so that the second snap-fit ​​portion 11212 can be engaged in the second snap-fit ​​groove 11312. After the second snap-fit ​​portion 11212 is engaged in the second snap-fit ​​groove 11312, the first snap-fit ​​portion 11211 can be extended from the inner wall of the first connecting portion 112, so that the first snap-fit ​​portion 11211 can be engaged in the first snap-fit ​​groove on the second connecting portion 113. Thus, the first connecting portion 112 and the second connecting portion 113 can be connected through the cooperation of the first snap-fit ​​portion 11211 with the second snap-fit ​​groove 11312 and the second snap-fit ​​portion 11212 with the second snap-fit ​​groove 11312.

[0074] This bidirectional limiting between the first connecting part 112 and the second connecting part 113 can reduce or avoid the movement of adjacent protective sleeves 110 along the axial direction (i.e., Figure 3 The x-direction of the protective sleeve 110 moves or shifts, thereby achieving axial positioning between two adjacent protective sleeves 110.

[0075] By making the first snap-fit ​​portion 11211 retractably disposed on the inner wall of the first connecting portion 112, when the first connecting portion 112 of the protective sleeve 110 is connected to the second connecting portion 113 of another protective sleeve 110, interference of the first snap-fit ​​portion 11211 with the cooperation between the second snap-fit ​​portion 11212 and the second snap-fit ​​groove 11312 can be avoided, which can effectively improve the rationality of the cooperation between the first connecting portion 112 and the second connecting portion 113.

[0076] See also Figure 3 As shown, the protective sleeve 110 may include a first protective part 115 and a second protective part 116 that are disposed opposite to and connected to each other. For example, the cross-section of the first protective part 115 and the second protective part 116 may be semi-circular, and the two ends of the first protective part 115 and the second protective part 116 may fit together to form a complete protective sleeve 110. This facilitates the installation and removal of the protective sleeve 110 on the cable. For example, when one of the protective sleeves 110 is damaged, the first protective part 115 and the second protective part 116 can be separated to remove the protective sleeve 110 from the cable, eliminating the need to remove the entire cable protection device 100 from the cable for replacement. This effectively improves the flexibility of the protective sleeve 110 on the cable and enhances the overall flexibility of the cable protection device 100.

[0077] One end of the first protective part 115 and the second protective part 116 can be connected by a hinge 117 (see reference). Figure 1 The first protective part 115 and the second protective part 116 are rotated together (as shown). This ensures that the first protective part 115 and the second protective part 116 are always connected, preventing the loss of one of the protective parts and improving the structural stability of the protective sleeve 110.

[0078] A first locking member 1151 may be provided on the outer wall of the other end of the first connecting part 112, and a second locking member 1161 that cooperates with the first locking member 1151 may be provided on the outer wall of the other end of the second connecting part 113. The other ends of the first protective part 115 and the second protective part 116 can be detachably connected through the cooperation of the first locking member 1151 and the second locking member 1161. For example, the first locking member 1151 may be a protruding buckle portion, and the second locking member 1161 may be a buckle with a groove. The buckle can be engaged with the buckle portion to realize the connection of the other ends of the first protective part 115 and the second protective part 116.

[0079] When it is necessary to put the protective sleeve 110 on the cable or to remove the protective sleeve 110 from the cable, it can be installed or removed by the cooperation of the first locking member 1151 and the second locking member 1161. This can effectively improve the reliability of the connection between the first protective part 115 and the second protective part 116, and also facilitate the disassembly and connection between the first protective part 115 and the second protective part 116.

[0080] See also Figure 3 As shown, the first protective part 115 has a first engaging portion 1152 on its mating surface facing the second protective part 116, and the second protective part 116 has a second engaging portion 1162 on its mating surface facing the first protective part 115, which engages with the first engaging portion 1152. The first engaging portion 1152 and the second engaging portion 1162 engage with each other. For example, the first engaging portion 1152 can be a protruding structure, and the second engaging portion 1162 can be a concave structure, or the first engaging portion 1152 can be a concave structure, and the second engaging portion 1162 can be a protruding structure. Through the engagement between the first engaging portion 1152 and the second engaging portion 1162, an axial (i.e., axial) connection can be achieved between the first protective part 115 and the second protective part 116. Figure 3 (x-direction) and radial (i.e.) Figure 3 The limiting function in the y direction can effectively reduce or avoid misalignment between the first protective part 115 and the second protective part 116 at the mating surface, thereby effectively improving the connection accuracy between the first protective part 115 and the second protective part 116 and enhancing the overall structural stability and reliability of the protective sleeve 110.

[0081] Figure 4 for Figure 3 A magnified view of region A in the middle.

[0082] See Figure 4 As shown, a first mounting groove 1122 may be formed on the inner wall of the first connecting portion 112, and at least a portion of the first snap-fit ​​portion 11211 may be located within the first mounting groove 1122. The protective sleeve 110 may also include an adjusting rod 114, which may include an operating section 1141 and a connecting section 1142 connected to each other. The side of the first snap-fit ​​portion 11211 facing the first mounting groove 1122 may have a threaded hole 11213, wherein a portion of the operating section 1141 extends outward from the outside of the first connecting portion 112, and the outer periphery of the connecting section 1142 may be provided with external threads. The connecting section 1142 may be located within the first mounting groove 1122 and engage with the threaded hole 11213 on the first snap-fit ​​portion 11211. The length of the first connecting portion 112 within the first mounting groove 1122 can be adjusted by engaging with the threaded hole 11213.

[0083] For example, a through hole can be provided on the first connecting portion 112, and the adjusting rod 114 can pass through the through hole, with part of the operating section 1141 located outside the first connecting portion 112, while the connecting section 1142 is located in the first mounting groove 1122 inside the first connecting portion 112. A nut can be provided on the first connecting portion 112, and a threaded hole 11213 can be provided on the nut, so that the connecting section 1142 can be rotatably connected to the first snap-fit ​​portion 11211 through the nut.

[0084] When the first connecting part 112 needs to be extended or retracted, the operating section 1141 can be rotated on the outside of the first connecting part 112, so that the operating section 1141 can drive the connecting section 1142 to rotate together. When the connecting section 1142 rotates, the nut can move along the axial direction of the connecting section 1142, so that the nut can drive the first connecting part 112 to move together, thereby allowing the first connecting part 112 to retract into the first mounting groove 1122. Conversely, when it is necessary to extend the first connecting part 112 from the first mounting groove 1122, the adjusting rod 114 can be rotated in the opposite direction, so that the connecting section 1142 rotates in the opposite direction, thereby allowing the nut to drive the first connecting part 112 to move outward from the first mounting groove 1122.

[0085] See also Figure 4 As shown, a limiting plate 1143 can also be provided on the adjusting rod 114, and the limiting plate 1143 can be located between the operating section 1141 and the connecting section 1142. A limiting groove that cooperates with the limiting plate 1143 can also be provided on the first connecting part 112, and the limiting groove can be connected to the first assembly groove 1122. The limiting plate 1143 can be locked in the limiting groove. The diameter of the limiting plate 1143 can be larger than the diameter of the operating section 1141 and the connecting section 1142. The limiting groove can limit the limiting plate 1143, which can reduce or avoid the adjusting rod 114 from moving around, thereby affecting the adjustment of the first locking part 11211, and helping to improve the reliability and accuracy of the adjustment of the first locking part 11211.

[0086] Figure 5 for Figure 3 A magnified view of region B in the middle.

[0087] See Figure 4 and Figure 5As shown, the bottom walls of the first latching groove 11311 and the second latching groove 11312 are respectively provided with a first magnetic block 11313 and a second magnetic block 11314. The end of the first latching portion 11211 is provided with a third magnetic block 11214 whose magnetism is opposite to that of the first magnetic block 11313, and the end of the second latching portion 11212 is provided with a fourth magnetic block 11215 whose magnetism is opposite to that of the second magnetic block 11314. The first magnetic blocks 11313 and the second magnetic blocks 11314 can be evenly distributed on the bottom walls of the first latching groove 11311 and the second latching groove 11312, and the first magnetic blocks 11313 and the second magnetic blocks 11314 can be staggered, that is, the projections of the first magnetic blocks 11313 and the second magnetic blocks 11314 in the axial direction of the second connecting portion 113 do not coincide. Correspondingly, the third magnetic block 11214 and the fourth magnetic block 11215 correspond to the first magnetic block 11313 and the second magnetic block 11314, respectively.

[0088] In this design, the first latching portion 11211 and the first latching groove 11311, as well as the second latching portion 11212 and the second latching groove 11312, are all clearance fits. This allows the first magnetic block 11313 and the third magnetic block 11214 to be alternately attracted with the second magnetic block 11314 and the fourth magnetic block 11215. For example, during the magnetic block attraction process, when the first magnetic block 11313 is attracted with the third magnetic block 11214, there will be a certain gap between the end of the second latching portion 11212 and the bottom wall of the second latching groove 11312, preventing the second magnetic block 11314 and the fourth magnetic block 11215 from attracting each other. Conversely, when the second magnetic block 11314 and the fourth magnetic block 11215 are attracted to each other, the first magnetic block 11313 cannot attract each other. When the cable protection device 100 swings between two adjacent protective sleeves 110, the gap between the non-magnetically attracted snap-fit ​​part and the snap-fit ​​groove is relatively large, allowing the two adjacent protective sleeves 110 to swing, thus enabling the cable protection device 100 to bend as a whole. The cooperation between the snap-fit ​​groove and the snap-fit ​​part where the magnetic blocks attract each other provides a certain limit to the swinging of the protective sleeves 110, preventing excessive swing amplitude and thus avoiding excessive bending of the cable protection device 100. This keeps the bending of the cable protection device 100 within a certain range, effectively improving the rationality of the bending of the cable protection device 100.

[0089] Figure 6 This is a schematic diagram of a fixed sleeve from one perspective, provided as an embodiment of this application. Figure 7 This is a schematic diagram of a fixed sleeve from another perspective, provided as an embodiment of this application. Figure 8 This is an exploded view of a fixing sleeve provided in an embodiment of this application.

[0090] in, Figures 6 to 8 The diagram shown is of one half of the fixed sleeve, not the complete structure.

[0091] The cable protection device 100 may also include a fixing sleeve 120 (see reference). Figure 1 As shown), the fixing sleeve 120 can be disposed at the end of the cable protection device 100. For example, the fixing sleeve 120 can be connected to the first connecting portion 112 located at the end of the cable protection device 100. For example, a slot 1123 can be provided on the side of the first connecting portion 112 facing away from the main body portion 111 (see Figure 123). Figure 1 or Figure 2 As shown), a locking post 121 that mates with the locking groove 1123 can be provided on the end face of the fixing sleeve 120 (see reference). Figure 1 As shown, the locking post 121 can be locked in the locking groove 1123 so that the fixing sleeve 120 and the first connecting part 112 can be connected through the cooperation between the locking groove 1123 and the locking post 121.

[0092] Among them, see Figure 6 As shown, a retaining plate 122 can be provided on the inner wall of the fixing sleeve 120. The retaining plate 122 can abut against the cable inside the cable protection device 100 to fix the position of the cable within the cable protection device 100. For example, through the abutting action of the retaining plate 122 against the cable, the cable can be secured between the retaining plate 122 and the inner wall of the cable protection device 100. This effectively prevents the cable from shifting within the cable protection device 100, thereby effectively improving the firmness and reliability of the cable protection device 100 on the cable.

[0093] For example, combining Figure 7 and Figure 8As shown, the fixed sleeve 120 may also include a gear shaft 123. The fixed sleeve 120 may have a mounting hole 124, and mounting seats 125 may be provided on both sides of the mounting hole 124. A second mounting groove 1251 may be provided on the mounting seat 125. The gear shaft 123 can be rotatably disposed within the second mounting groove 1251, and the clamping plate 122 can be located on the gear shaft 123. By rotating the gear shaft 123, the deflection angle of the clamping plate 122 within the fixed sleeve 120 can be adjusted. For example, when the gear shaft 123 is rotated so that the clamping plate 122 is perpendicular to the axis of the fixed sleeve 120, the distance between the end of the clamping plate 122 and the inner wall of the fixed sleeve 120 is relatively small, which can fix cables with smaller diameters. When the gear shaft 123 is rotated so that the included angle between the clamping plate 122 and the axis of the fixed sleeve 120 is an acute angle, the distance between the end of the clamping plate 122 and the inner wall of the fixed sleeve 120 is relatively large, which can fix cables with larger diameters. This allows the fixing sleeve 120 to fix cables of different diameters, effectively improving the flexibility of the cable protection device 100 in fixing cables.

[0094] See also Figure 8 As shown, a fixing tooth 126 that meshes with the gear shaft 123 can be provided on the inner wall of the mounting hole 124. The fixing tooth 126 can be engaged in one of the tooth grooves of the gear shaft 123. The fixing tooth 126 can limit and fix the gear shaft 123, preventing the gear shaft 123 from rotating, so that the gear shaft 123 can be fixed in a certain position, thereby fixing the clamping plate 122 in a certain position for cable clamping. This effectively improves the reliability and stability of the clamping plate 122 in fixing the cable.

[0095] See also Figure 8 As shown, a spring 1252 can be provided in the second mounting groove 1251. The spring 1252 can be located on the side of the gear shaft 123 opposite to the fixed tooth 126. The spring 1252 can apply a spring force to the gear shaft 123 so that one tooth groove of the gear shaft 123 can be firmly locked onto the fixed tooth 126. This can reduce or prevent the gear shaft 123 from dislodging from the fixed tooth 126, and help improve the firmness and reliability of the fit between the gear shaft 123 and the fixed tooth 126.

[0096] When it is necessary to rotate the gear shaft 123 to adjust the position of the clamping plate 122, the gear shaft 123 can be pressed towards the spring, so that the spring 1252 is in a compressed state, thereby disengaging the gear shaft 123 from the fixed tooth 126. At this time, the gear shaft 123 can be rotated to adjust the position of the clamping plate 122. After the clamping plate 122 is adjusted to the appropriate position, the fixed tooth 126 can be engaged in the corresponding tooth groove on the gear shaft 123, thereby completing the position adjustment of the clamping plate 122.
