Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

As described in the background art, the cable is inevitably bent during the use process, and if the bending amplitude of the cable is too large, the service life of the cable is affected, and even the cable is severely broken. However, current cable protection devices can only realize sealing protection of the cable, i.e. the cable can be prevented from entering the cable from external water stains and stains. And the bending prevention function of the cable is difficult to realize, and the protection performance of the cable is reduced.

In order to solve the problems, researchers improve the cable protection device, the cable protection device comprises a plurality of end-to-end protection sleeves, and limited amplitude swinging can be carried out between two adjacent protection sleeves, so that a cable in the cable protection device can be bent with limited amplitude, but the bending amplitude is not too large, thereby effectively reducing or avoiding the cable from being bent to a larger extent, preventing the cable from being damaged or broken due to the overlarge bending amplitude, being beneficial to improving the working stability of the cable and prolonging the service life of the cable.

Fig. 1 is a schematic structural diagram of a cable protection device provided in an embodiment of the present application, fig. 2 is a schematic structural diagram of a protection sleeve provided in an embodiment of the present application, and fig. 3 is a schematic structural diagram of a protection sleeve provided in an embodiment of the present application in another state.

Referring to fig. 1, the present embodiment provides a cable protection device 100, and the cable protection device 100 may be sleeved on the outer circumference of a cable to protect the cable. The cable protection device 100 may include a plurality of protective sleeves 110 connected end to end. For example, the number of protective sleeves 110 may be varied to vary the length of the cable protective device 100 according to the length requirements of the cable to be protected, so that the cable protective device 100 may meet the protection requirements of cables of different lengths.

The protective case 110 may include a main body portion 111 and first and

second connection portions

112 and 113 at both ends of the main body portion 111, respectively. The first connection portion 112 of the protective sleeve 110 may be connected with the second connection portion 113 of the adjacent other protective sleeve 110, so as to connect the two adjacent protective sleeves 110.

As shown in fig. 2 and fig. 3, the inner wall of the first connecting portion 112 may have a clamping member 1121, the outer periphery of the second connecting portion 113 is provided with a clamping groove 1131 matched with the clamping member 1121, and the clamping member 1121 on the protecting sleeve 110 may be clamped in the clamping groove 1131 on the other protecting sleeve 110 adjacent to the clamping member 1121, so that two adjacent protecting sleeves 110 may be connected by matching the clamping member 1121 with the clamping groove 1131. For example, in the process of connecting two adjacent protection sleeves 110, the second connection portion 113 of one protection sleeve 110 may extend into the first connection portion 112 of the other protection sleeve 110, so that the clamping piece 1121 on the inner wall of the first connection portion 112 may be clamped in the clamping groove 1131 on the outer periphery of the second connection portion 113, thereby realizing connection of the two protection sleeves 110.

The clamping member 1121 and the clamping groove 1131 may be in clearance fit, so that the adjacent two protecting jackets 110 may swing with limited amplitude. That is, when the two protection sleeves 110 are connected, the connection relationship is flexible, and the fit between the clamping member 1121 and the clamping groove 1131 is loose, rather than being in a clamping state. Thereby allowing the entire cable guard 100 to bend and allowing cables located within the cable guard 100 to bend. To meet the bending requirements of the cable during use. The clamping relationship between the clamping member 1121 and the clamping groove 1131 may provide a certain limit for the swing between the two adjacent protective sleeves 110, so that the swing amplitude between the two adjacent protective sleeves 110 may be limited within a certain range, and thus the bending of the whole cable protection device 100 may be limited within a certain range. The cable protection device 100 can be prevented from being bent excessively, the cable in the cable protection device 100 is effectively prevented from being bent excessively, damage or breakage caused by the excessively large cable bending amplitude is prevented, and the protection performance of the cable protection device 100 to the cable is effectively improved.

With continued reference to fig. 3, the clamping member 1121 may include a first clamping portion 11211 and a second clamping portion 11212 axially distributed along the first connecting portion 112, and the clamping groove 1131 may include a first clamping groove 11311 and a second clamping groove 11312 axially distributed along the second connecting portion 113. The first clamping portion 11211 may be clamped in the first clamping groove 11311, and the second clamping portion 11212 may be clamped in the second clamping groove 11312. The first clamping portion 11211 is telescopically disposed on an inner wall of the first connecting portion 112.

When two adjacent protective sleeves 110 are connected, the first clamping 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 of the other protective sleeve 110 may extend into the first connecting portion 112 of the protective sleeve 110, so that the second clamping portion 11212 may be clamped in the second clamping groove 11312. After the second clamping portion 11212 is clamped in the second clamping groove 11312, at this time, the first clamping portion 11211 may extend from the inner wall of the first connecting portion 112, so that the first clamping portion 11211 may be clamped in the first clamping groove on the second connecting portion 113. So that the first connection portion 112 and the second connection portion 113 can be connected by the engagement of the first clamping portion 11211 with the second clamping groove 11312 and the second clamping portion 11212 with the second clamping groove 11312.

The bidirectional limit between the first connection portion 112 and the second connection portion 113 is achieved in this way, so that play or offset of two adjacent protective sleeves 110 along the axial direction (i.e., the x direction in fig. 3) can be reduced or avoided, and positioning between the two adjacent protective sleeves 110 in the axial direction is achieved.

By arranging the first locking portion 11211 on the inner wall of the first connecting portion 112 so as to be telescopic, when the first connecting portion 112 of the protective case 110 is connected to the second connecting portion 113 of the other protective case 110, interference between the first locking portion 11211 and the second locking portion 11212 and the second locking groove 11312 can be avoided, and the rationality of the coupling between the first connecting portion 112 and the second connecting portion 113 can be effectively improved.

With continued reference to fig. 3, the protective case 110 may include a first protective portion 115 and a second protective portion 116 disposed opposite to each other and connected, for example, a cross section of the first protective portion 115 and the second protective portion 116 may be semicircular, and two ends of the first protective portion 115 and the second protective portion 116 may be attached to each other to form the complete protective case 110, so that installation and removal of the protective case 110 on a cable may be facilitated. For example, when one of the protective sleeves 110 is damaged, the first protective portion 115 and the second protective portion 116 can be separated to detach the protective sleeve 110 from the cable, so that the whole cable protecting device 100 is omitted from being removed from the cable and replaced, the flexibility of the protective sleeve 110 in setting the cable can be effectively improved, and the overall flexibility of the cable protecting device 100 is improved.

One end of the first protection portion 115 and one end of the second protection portion 116 may be rotatably connected by a hinge member 117 (see fig. 1). In this way, the first protection part 115 and the second protection part 116 can be always connected together, so that one protection part can be prevented from being lost, and the structural stability of the protection sleeve 110 can be improved.

The outer wall of the other end of the first connection part 112 may be provided with a first locking piece 1151, the outer wall of the other end of the second connection part 113 may be provided with a second locking piece 1161 engaged with the first locking piece 1151, and the other ends of the first protection part 115 and the second protection part 116 may be detachably connected by the engagement of the first locking piece 1151 and the second locking piece 1161. For example, the first locking member 1151 may be a protruding latch portion, and the second locking member 1161 may be a latch member having a groove, and the latch member may be snapped onto the latch portion to achieve connection of the other ends of the first protection portion 115 and the second protection portion 116.

When it is desired to fit the protective sheath 110 over the cable or to remove the protective sheath 110 from the cable, the attachment or detachment may be performed by the mating of the first locking member 1151 and the second locking member 1161. In this way, the reliability of the connection between the first protection portion 115 and the second protection portion 116 can be effectively improved, and the detachment and connection between the first protection portion 115 and the second protection portion 116 can be facilitated.

With continued reference to fig. 3, the first engaging portion 1152 is disposed on a bonding surface of the first protection portion 115 facing the second protection portion 116, and the second engaging portion 1162 is disposed on a bonding surface of the second protection portion 116 facing the first protection portion 115, which is engaged with the first engaging portion 1152. The first engaging portion 1152 engages with the second engaging portion 1162. For example, the first engaging portion 1152 may have a convex structure, the second engaging portion 1162 may have a concave structure, or the first engaging portion 1152 may have a concave structure, and the second engaging portion 1162 may have a convex structure. Through the cooperation between first clamping portion 1152 and the second clamping portion 1162, can play spacing effect of axial (i.e. x direction in fig. 3) and radial (i.e. y direction in fig. 3) between first protection portion 115 and second protection portion 116, dislocation between first protection portion 115 and second protection portion 116 in the faying face department can be effectively reduced or avoided to effectively improve the connection precision between first protection portion 115 and the second protection portion 116, promote the holistic structural stability and the reliability of protective sheath 110.

Fig. 4 is an enlarged view of the area a in fig. 3.

Referring to fig. 4, a first fitting groove 1122 may be formed in an inner wall of the first connecting portion 112, and at least a portion of the first clamping portion 11211 may be located in the first fitting groove 1122. The protective sleeve 110 may also include an adjustment rod 114, and the adjustment rod 114 may include an operative section 1141 and a connective section 1142 connected. The first fastening portion 11211 may have a threaded hole 11213 on a surface facing the first fastening portion 1122, wherein a portion of the operating section 1141 extends outside the first connecting portion 112, an outer circumference of the connecting section 1142 may be provided with an external thread, and the connecting section 1142 may be located in the first fastening portion 1122 and cooperate with the threaded hole 11213 on the first fastening portion 11211. The connection section 1142 may adjust the mating length of the first connection portion 112 within the first fitting groove 1122 by mating with the threaded bore 11213.

For example, a through hole may be formed in the first connecting portion 112, and the adjusting rod 114 may be inserted through the through hole, so that a portion of the operating section 1141 is located outside the first connecting portion 112, and the connecting section 1142 is located in the first fitting groove 1122 inside the first connecting portion 112. A nut member may be provided on the first coupling portion 112, and the screw hole 11213 may be opened in the nut member. So that the connecting section 1142 may be rotatably coupled to the first snap-fit portion 11211 by a nut member.

When the first connection portion 112 needs to be telescopically adjusted, the operation section 1141 can be rotated at the outer side of the first connection portion 112, so that the operation section 1141 can drive the connection section 1142 to rotate together. The connecting section 1142 may be rotated to move the nut member along the axial direction of the connecting section 1142, so that the nut member may drive the first connecting portion 112 to move together, thereby allowing the first connecting portion 112 to retract into the first fitting groove 1122. Conversely, when it is desired to extend first connecting portion 112 from within first fitting groove 1122, adjustment lever 114 can be rotated in a reverse direction to rotate connecting section 1142 in a reverse direction, thereby causing nut member to move first connecting portion 112 outwardly of first fitting groove 1122.

With continued reference to FIG. 4, a limit disk 1143 may also be provided on adjustment lever 114, and limit disk 1143 may be located between operating section 1141 and connecting section 1142. The first connecting portion 112 may further be provided with a limiting groove matched with the limiting plate 1143, and the limiting groove may be communicated with the first assembling groove 1122, and the limiting plate 1143 may be clamped in the limiting groove. The diameter of the limiting plate 1143 may be greater than the diameters of the operating section 1141 and the connecting section 1142, and the limiting groove may play a limiting role on the limiting plate 1143, so that play of the adjusting rod 114 may be reduced or avoided, further the adjustment of the first clamping portion 11211 is affected, and the reliability and accuracy of the adjustment of the first clamping portion 11211 are improved.

Fig. 5 is an enlarged view of a region B in fig. 3.

Referring to fig. 4 and 5, bottom walls of the first clamping groove 11311 and the second clamping groove 11312 are respectively provided with a first magnetic block 11313 and a second magnetic block 11314. The end of the first clamping portion 11211 is provided with a third magnetic block 11214 having a magnetic property opposite to that of the first magnetic block 11313, and the end of the second clamping portion 11212 is provided with a fourth magnetic block 11215 having a magnetic property opposite to that of the second magnetic block 11314. The first magnetic blocks 11313 and the second magnetic blocks 11314 can be uniformly distributed on the bottom walls of the first clamping groove 11311 and the second clamping groove 11312, and the first magnetic blocks 11313 and the second magnetic blocks 11314 can be arranged in a staggered manner, that is, the projections of the first magnetic blocks 11313 and the second magnetic blocks 11314 on the axial direction of the second connecting portion 113 are not overlapped. Accordingly, the third and fourth

magnetic blocks

11214 and 11215 correspond to the first and second

magnetic blocks

11313 and 11314, respectively.

The first clamping portion 11211 and the first clamping groove 11311, and the second clamping portion 11212 and the second clamping groove 11312 are in clearance fit, so that the first magnetic block 11313 and the third magnetic block 11214 and the second magnetic block 11314 and the fourth magnetic block 11215 can be adsorbed in a staggered manner. For example, in the process of magnetic block adsorption, when the first magnetic block 11313 and the third magnetic block 11214 are adsorbed, at this time, a first certain gap exists between the end of the second clamping portion 11212 and the bottom wall of the second clamping groove 11312, so that the second magnetic block 11314 and the fourth magnetic block 11215 cannot be adsorbed mutually. In contrast, when the second magnetic block 11314 and the fourth magnetic block 11215 are attracted to each other, the first magnetic block 11313 and the first magnetic block 11313 cannot be attracted to each other. In this way, when the adjacent two protecting jackets 110 swing, the gap between the clamping part which is not adsorbed by the magnet and the clamping groove is relatively large, so that the adjacent two protecting jackets 110 can swing, and the whole cable protecting device 100 can be bent. And cooperation between clamping groove and the joint portion that the magnetic path adsorbs each other can provide certain limiting displacement to the swing between the protective sheath 110, can avoid the wobbling range between the protective sheath 110 too big to avoid the bending amplitude of cable protection device 100 too big, make the bending of cable protection device 100 can be controlled in certain within range, effectively improved the rationality of cable protection device 100 bending.

Fig. 6 is a schematic structural diagram of a fixing sleeve provided in an embodiment of the present application under one view angle, fig. 7 is a schematic structural diagram of a fixing sleeve provided in an embodiment of the present application under another view angle, and fig. 8 is an exploded view of a fixing sleeve provided in an embodiment of the present application.

Fig. 6 to 8 show a schematic structural view of one half of the fixing sleeve, but not a complete schematic structural view.

The cable protection device 100 may further include a fixing sleeve 120 (shown with reference to fig. 1), and the fixing sleeve 120 may be disposed at an end of the cable protection device 100, for example, the fixing sleeve 120 may be connected with the first connection portion 112 at the end of the cable protection device 100. For example, a locking groove 1123 (shown in fig. 1 or 2) may be formed on a surface of the first connection portion 112 facing away from the main body portion 111, a locking post 121 (shown in fig. 1) that mates with the locking groove 1123 may be provided on an end surface of the fixing sleeve 120, and the locking post 121 may be locked in the locking groove 1123, so that the fixing sleeve 120 and the first connection portion 112 may be connected by mating between the locking groove 1123 and the locking post 121.

As shown in fig. 6, a clamping plate 122 may be disposed on an inner wall of the fixing sleeve 120, and the clamping plate 122 may abut against a cable in the cable protection device 100 to fix a position of the cable in the cable protection device 100. For example, the cable can be caught between the card 122 and the inner wall of the cable protector 100 by the abutting action of the card 122 on the cable. Therefore, the cable can be effectively prevented from moving in the cable protection device 100, and the firmness and reliability of sleeving the cable protection device 100 on the cable can be effectively improved.

For example, as shown in fig. 7 and 8, the fixing sleeve 120 may further include a gear shaft 123, the fixing sleeve 120 may be provided with a mounting hole 124, two sides of the mounting hole 124 may be provided with mounting seats 125, the mounting seats 125 may be provided with second assembly grooves 1251, the gear shaft 123 may be rotatably disposed in the second assembly grooves 1251, and the clamping plate 122 may be located on the gear shaft 123. By rotating the gear shaft 123, the deflection angle of the clamping plate 122 in the fixing sleeve 120 can be adjusted, for example, when the gear shaft 123 is rotated to enable the clamping plate 122 to be perpendicular to the axis of the fixing sleeve 120, at this time, the distance between the end of the clamping plate 122 and the inner wall of the fixing sleeve 120 is relatively minimum, and the cable with smaller diameter can be fixed. When the gear shaft 123 is rotated to make the included angle between the clamping plate 122 and the axis of the fixing sleeve 120 be an acute angle, at this time, the distance between the end of the clamping plate 122 and the inner wall of the fixing sleeve 120 is relatively large, so that the cable with a large diameter can be fixed. Thus, the fixing sleeve 120 can fix cables with different diameters, and the flexibility of fixing the cable protection device 100 to the cables can be effectively improved.

With continued reference to fig. 8, a fixed tooth 126 engaged with the gear shaft 123 may be provided on an inner wall of the mounting hole 124, and the fixed tooth 126 may be caught in one of tooth grooves of the gear shaft 123. The fixed teeth 126 can limit and fix the gear shaft 123, and can prevent the gear shaft 123 from rotating, so that the gear shaft 123 can be fixed at a determined position, and the clamping plate 122 can be fixed at a determined position to be clamped and fixed by a cable. The reliability and stability of the fixing of the clamping plate 122 to the cable can be effectively improved.

With continued reference to fig. 8, a spring member 1252 may be disposed within the second mounting groove 1251, and the spring member 1252 may be located on the opposite side of the gear shaft 123 from the stationary teeth 126. The spring member 1252 can apply elastic force to the gear shaft 123, so that a tooth slot of the gear shaft 123 can be firmly clamped on the fixed teeth 126, which can reduce or avoid the gear shaft 123 from falling out of the fixed teeth 126, and is helpful for improving the firmness and reliability of the cooperation between the gear shaft 123 and the fixed teeth 126.

When the gear shaft 123 needs to be rotated to adjust the position of the clamping plate 122, the gear shaft 123 can be pressed towards the direction of the spring, so that the spring member 1252 is in a compressed state, and the gear shaft 123 and the fixed teeth 126 are separated from the clamping relationship. At this time, the gear shaft 123 may be rotated to adjust the position of the clamping plate 122, and after the clamping plate 122 is adjusted to a proper position, the fixed teeth 126 may be clamped in the corresponding tooth slots on the gear shaft 123, so as to complete the position adjustment of the clamping plate 122.
