[0016] Compared with the prior art, the present invention provides a cable protection sleeve, which has the following beneficial effects:

[0017] 1. The cable protection sleeve is inserted by aligning the insertion rod on the second mounting ring with the first arc-shaped hole on the first mounting ring, and the L-shaped limit rod enters the second arc-shaped hole at the same time. Then, the second mounting ring is rotated to drive the insertion rod and the L-shaped limit rod to rotate clockwise along the inner walls of the first arc-shaped hole and the second arc-shaped hole respectively. Through the smooth inclined surface on the clamping rod, the clamping rod slides up and compresses the first spring. Then, under the action of the first spring resetting, the clamping rod enters the limit groove on the L-shaped limit rod, thereby clamping the L-shaped limit rod to limit the position, thereby completing the installation between the first mounting ring and the second mounting ring, and then the first sleeve and the second sleeve are quickly installed and fixed, which greatly improves the installation efficiency of the cable protection sleeve, reduces labor intensity, and saves a lot of installation time.

[0018] 2. When the cable protective sleeve is inserted into the first installation ring through the annular insertion rod, it will contact the annular inclined plate, so that the three annular inclined plates drive the sliding rod and the annular clamping plate at the bottom to slide down. The three annular clamping plates clamp the cable body, thereby clamping and fixing the cable body. The cable body can be clamped and fixed while being installed between the first sleeve and the second sleeve, which can prevent the cable body from moving when the protective sleeve is put on, and help to speed up the installation efficiency of the cable body installation sleeve.

[0019] 3. The cable protection sleeve is inserted into the second arc hole through the L-shaped limit rod and will hit the block while rotating along the second arc hole. The block drives the arc rack to slide into the arc groove in the second arc hole, and drives the arc tube to slide at the same time, and then meshes with the gear, so that the gear drives the rotating rod to rotate, and drives the driven rod to rotate synchronously through the synchronous belt, so that the driven rod drives the protrusion to rotate, and the protruding part of the protrusion rotates and hits the top of the push rod, so that the push rod drives the connecting ring and the piston block to slide toward the inner direction of the sealing tube, so that the piston block makes a piston movement, and the air in the sealing tube is squeezed out from the inflation tube into the annular airbag. The annular airbag will tightly fill the annular groove between the first mounting ring and the second mounting ring, so that the first sleeve and the second sleeve are tightly fitted, which can ensure the sealing inside the sleeve, prevent the cable body from being damaged and affected by moisture when the cable body is affected, and effectively extend the service life of the cable body.

[0020] 4. When the cable protection sleeve enters the cavity of the first mounting ring through the insertion rod, it will first contact the arc plate, and then the arc plate will drive the extrusion rod to slide on the annular inclined plate toward the cavity of the first mounting ring. When the extrusion rod drives the slide rail to slide, it will drive the extrusion plate to compress the cylindrical airbag, so that the air in the cylindrical airbag is squeezed out from the folding hose into the cavity of the annular clamping plate, and blown out from the inclined hole to blow off the dust and other impurities on the surface of the cable body. Therefore, before the annular clamping plate clamps the cable body, the dust and other impurities on the cable body can be cleared in advance, which can make the clamping and fixation of the cable body more stable, prevent the cable body from moving and causing accidents, and ensure the electrical stability of the cable.

[0040] Example 1: Reference Figure 1-Figure 16 A cable protection sleeve comprises a cable body 1 and a first sleeve 2 and a second sleeve 3 sleeved on the outside of the cable body 1, a first mounting ring 4 is arranged on the first sleeve 2, a second mounting ring 5 is arranged on the second sleeve 3, a cavity is opened inside the first mounting ring 4, and further comprises: an insertion rod 6, fixedly connected to the second mounting ring 5; an L-shaped limit rod 7, fixedly connected to the insertion rod 6, a limit groove 8 is opened on the top surface of the L-shaped limit rod 7; a first arc hole 9 is opened on the surface of the first mounting ring 4, a second arc hole 10 is opened on the surface of the first mounting ring 4; a clamping rod 11, slidably connected to the first mounting ring 4, a smooth inclined surface is opened on the clamping rod 11, and a pull ring 12 is fixedly connected to the surface of the clamping rod 11; a first spring 13, sleeved on the clamping rod 11, and the two ends of the first spring 13 are respectively against the pull ring 12 and the first mounting ring 4.

[0041] In the present invention, when it is necessary to install the cable protection sleeve, after the first sleeve 2 and the second sleeve 3 are sleeved on the cable body 1, the insertion rod 6 on the second mounting ring 5 is aligned with the first arc-shaped hole 9 on the first mounting ring 4 and inserted, and the L-shaped limiting rod 7 enters the second arc-shaped hole 10 at the same time, and then the second mounting ring 5 is rotated to drive the insertion rod 6 and the L-shaped limiting rod 7 to rotate clockwise along the inner walls of the first arc-shaped hole 9 and the second arc-shaped hole 10 respectively. When the L-shaped limiting rod 7 rotates to the clamping rod 11, the L-shaped limiting rod 7 passes through the smooth inclined surface on the clamping rod 11, and the clamping rod 11 slides up and compresses the first spring 13. Subsequently, after the L-shaped limiting rod 7 passes, the clamping rod 11 enters the L-shaped The limit groove 8 on the limit rod 7 is used to clamp the L-shaped limit rod 7 and limit it, thereby completing the installation between the first mounting ring 4 and the second mounting ring 5, and then quickly installing and fixing the first sleeve 2 and the second sleeve 3, which greatly improves the installation efficiency of the cable protection sleeve, reduces labor intensity, and saves a lot of installation time; when it is necessary to disassemble the first sleeve 2 and the second sleeve 3, it is only necessary to pull the pull ring 12 outward to drive the clamping rod 11 to disengage from the limit groove 8 on the L-shaped limit rod 7, and the L-shaped limit rod 7 and the insertion rod 6 can be disengaged from the second arc hole 10 and the first arc hole 9 respectively, completing the rapid disassembly between the first mounting ring 4 and the second mounting ring 5, which is convenient for the subsequent maintenance of the cable body 1.

[0042] Example 2: Reference Figure 1-Figure 13 , which is basically the same as the first embodiment, and further, the insertion rod 6, the L-shaped limiting rod 7, the first arc-shaped hole 9, the second arc-shaped hole 10, and the clamping rod 11 are all provided in three groups, and the three groups of the insertion rod 6, the L-shaped limiting rod 7, the first arc-shaped hole 9, the second arc-shaped hole 10, and the clamping rod 11 are all arranged in a circular array with the center line of the first mounting ring 4 as the axis of symmetry, and a sliding rod 14 passes through the surface of the first sleeve 2, and the sliding rod 14 is arranged in three groups in a circular array around the first sleeve 2, and the three groups of sliding rods 14 are all slidably connected to the first sleeve 2.

[0043] In the present invention, through three groups of insert rods 6, L-shaped limit rods 7, first arc holes 9, second arc holes 10, and clamping rods 11, the installation effect between the first sleeve 2 and the second sleeve 3 can be made more stable, more firm, and not easy to loosen.

[0044] The top surface of the sliding rod 14 is fixedly connected with an annular inclined plate 15, and the end of the sliding rod 14 away from the annular inclined plate 15 is fixedly connected with an annular clamping plate 16. The surface of the sliding rod 14 in the cavity close to the first mounting ring 4 is sleeved with a second spring 1501, and the two ends of the second spring 1501 are respectively against the inner walls of the annular inclined plate 15 and the cavity of the first mounting ring 4.

[0045] In the present invention, when the protective sleeve is put on the cable body 1, the cable body 1 is easy to slide or fall off, which greatly affects the installation progress of the staff. When the insertion rod 6 enters the cavity of the first mounting ring 4, it will conflict with the annular inclined plate 15. Since the annular inclined plate 15 can only slide up and down in the first sleeve 2 and the first mounting ring 4, and then in the process of inserting the insertion rod 6 into the first mounting ring 4, the three annular inclined plates 15 drive the sliding rod 14 and the annular clamping plate 16 at the bottom to slide down, and the three annular clamping plates 16 clamp the cable body 1, thereby clamping and fixing the cable body 1, and the cable body 1 can be clamped and fixed while being installed between the first sleeve 2 and the second sleeve 3, which can prevent the cable body 1 from moving when the protective sleeve is put on, and help to speed up the installation efficiency of the sleeve of the cable body 1.

[0046] Example 3: Reference Figure 1-Figure 16 , which is basically the same as the first embodiment, and further, a cavity is provided inside the annular clamping plate 16, an oblique hole 17 is provided on the bottom surface of the annular clamping plate 16, an arc groove is provided on the side wall of the second arc hole 10, an arc guide rod 18 is fixedly connected to the inner wall of the arc groove of the second arc hole 10, an arc tube 19 is slidably connected to the arc guide rod 18, an arc rack 20 is fixedly connected to one end of the arc tube 19 away from the arc guide rod 18, and a sliding groove corresponding to the arc guide rod 18 is provided inside the arc rack 20.

[0047] A stopper 21 is fixedly connected to the surface of one end of the arc rack 20 away from the arc tube 19, and the arc rack 20 is slidably connected to the arc groove of the second arc hole 10. An arc spring 22 is sleeved on the surface of the arc guide rod 18, and the two ends of the arc spring 22 are respectively abutted against the arc tube 19 and the inner wall of the arc groove of the second arc hole 10. A rotating rod 23 is rotatably connected in the arc groove of the second arc hole 10, and a gear 24 is fixedly connected to the rotating rod 23, and the gear 24 is rotatably connected in the arc groove of the second arc hole 10.

[0048] In the present invention, when the sleeve is installed on the cable body 1, the L-shaped limit rod 7 is inserted into the second arc hole 10 and rotates along the second arc hole 10, and it will contact the block 21. The block 21 drives the arc rack 20 to slide into the arc groove in the second arc hole 10, and at the same time drives the arc tube 19 to slide, compressing the arc spring 22. At this time, the arc guide rod 18 can guide the sliding of the arc spring 22 and the arc rack 20, so that the sliding of the arc rack 20 is more stable, and then it engages with the gear 24, so that the gear 24 drives the rotating rod 23 to rotate; the arc spring 22 can make the arc rack 20 automatically reset.

[0049] A driven rod 25 is rotatably connected to the right inner wall of the first mounting ring 4, a synchronous belt 26 is transmission-connected between the driven rod 25 and the rotating rod 23, a protrusion 27 is fixedly connected to the end of the driven rod 25 away from the inner wall of the first mounting ring 4, a mounting plate 28 is fixedly connected to the right inner wall of the first mounting ring 4, and a sealing cylinder 29 is fixedly connected to the surface of one end of the mounting plate 28 away from the inner wall of the first mounting ring 4.

[0050] In the present invention, when the rotating rod 23 rotates, the driven rod 25 can be driven to rotate synchronously through the synchronous belt 26, and then the driven rod 25 drives the protrusion 27 to rotate.

[0051] The internal piston of the sealing cylinder 29 is connected to the piston block 30, and the surface of the piston block 30 is fixedly connected to the push rod 31, which passes through the sealing cylinder 29 and is slidably connected to the sealing cylinder 29. The surface of the push rod 31 passes through a connecting ring 32, and the connecting ring 32 is fixedly connected to the push rod 31. The surface of the push rod 31 is sleeved with a third spring 33, and the two ends of the third spring 33 are respectively against the connecting ring 32 and the sealing cylinder 29.

[0052] Annular grooves are provided on the surfaces of the first mounting ring 4 and the second mounting ring 5. An annular airbag 34 is fixedly connected in the annular groove of the first mounting ring 4. An inflation tube 35 is fixedly connected between the annular airbag 34 and the sealing tube 29. The inflation tube 35 passes through the first mounting ring 4 and is fixedly connected to the first mounting ring 4. An air intake tube 36 is fixedly connected to the inside of the sealing tube 29. The air intake tube 36 passes through the first mounting ring 4 and is fixedly connected to the first mounting ring 4.

[0053] In the present invention, when the projection 27 rotates, the protruding part of the projection 27 rotates and conflicts with the top of the push rod 31. Since the push rod 31 can only slide up and down in the sealing tube 29, the push rod 31 drives the connecting ring 32 and the piston block 30 to slide toward the inner direction of the sealing tube 29, so that the piston block 30 performs a piston movement, and the air in the sealing tube 29 is squeezed out from the inflation tube 35 into the annular airbag 34. Subsequently, when the protruding part of the projection 27 does not conflict with the push rod 31, the push rod 31, the connecting ring 32 and the piston block 30 are automatically reset under the action of the third spring 33, so that the piston block 30 performs a piston movement in the sealing tube 29, and the air is sucked from the first inflation tube 36 through the suction tube 36. The outside of the mounting ring 4 inhales air into the sealing tube 29, and then the protruding part of the protrusion 27 contacts the push rod 31 again, so that the air in the sealing tube 29 is again filled into the annular airbag 34 through the inflation tube 35, and the reciprocating operation is performed. When the arc-shaped rack 20 slides to the end of the arc-shaped groove of the second arc-shaped hole 10, the annular airbag 34 can be completely inflated. At this time, the annular airbag 34 will tightly fill the annular grooves between the first mounting ring 4 and the second mounting ring 5, so that the first sleeve 2 and the second sleeve 3 fit tightly, which can ensure the sealing inside the sleeve, prevent the cable body 1 from being damaged and affected by moisture when the cable body 1 is damaged, and effectively extend the service life of the cable body 1.

[0054] It should be noted that one-way valves are installed inside the inflation pipe 35 and the intake pipe 36 to prevent air from being squeezed out of the intake pipe 36 when the annular airbag 34 is inflated, and to prevent air from being sucked into the annular airbag 34 when air is inhaled. After the protective sleeve is installed, a rubber protective sleeve can be put on the intake pipe 36 to prevent rainwater, dust and other impurities from entering the intake pipe 36.

[0055] Example 4: Reference Figure 1-Figure 16 , which is basically the same as the first embodiment. Furthermore, an extrusion rod 37 passes through the annular inclined plate 15, and the extrusion rod 37 is slidably connected to the annular inclined plate 15. An arc plate 38 is fixedly connected to the right end surface of the extrusion rod 37. An arc-shaped accommodating groove 39 corresponding to the arc plate 38 is opened on the surface of the annular inclined plate 15. The sizes of the annular inclined plate 15 and the arc plate 38 are the same as the sizes of the first arc hole 9 and the second arc hole 10. A circular plate 40 is fixedly connected to the left inner wall of the first mounting ring 4, and a cylindrical airbag 41 is fixedly connected to the right side surface of the circular plate 40, and an extrusion plate 42 is fixedly connected to the right side surface of the cylindrical airbag 41.

[0056] In the present invention, when the insertion rod 6 enters the cavity of the first mounting ring 4, it will first contact the arc plate 38, and then the arc plate 38 drives the extrusion rod 37 to slide on the annular inclined plate 15 toward the inside of the cavity of the first mounting ring 4; because the annular inclined plate 15 and the arc plate 38 are the same size as the first arc-shaped hole 9, it can prevent the insertion rod 6 from detaching from the arc plate 38 and the annular inclined plate 15 when it rotates, so that the annular inclined plate 15 and the arc plate 38 always keep contact with the insertion rod 6.

[0057] A guide rod 43 is fixedly connected to the top left surface of the extrusion plate 42, and the guide rod 43 passes through the circular plate 40 and the first mounting ring 4, and is slidably connected to the circular plate 40 and the first mounting ring 4. A fourth spring 44 is sleeved on the surface of the guide rod 43, and the two ends of the fourth spring 44 are respectively abutted against the circular plate 40 and the extrusion plate 42. A slide rail 45 is fixedly connected to the right surface of the extrusion plate 42, and one end of the extrusion rod 37 away from the arc plate 38 is slidably connected in the slide rail 45.

The folding hose 46 passes through the first mounting ring 4 and the first sleeve 2, and is slidably connected to the first mounting ring 4 and the second sleeve 3.

[0058] In the present invention, when the extrusion rod 37 drives the slide rail 45 to slide, it drives the extrusion plate 42 to compress the cylindrical airbag 41, so that the air in the cylindrical airbag 41 is squeezed out from the folding hose 46 into the cavity of the annular clamping plate 16, and blown out from the inclined hole 17 to blow off the dust and other impurities on the surface of the cable body 1, so that before the annular clamping plate 16 clamps and fixes the cable body 1, the dust and other impurities on the cable body 1 can be cleared in advance, which can make the clamping and fixation of the cable body 1 more stable, prevent the cable body 1 from moving and causing accidents, and ensure the electrical stability of the cable; it should be noted that the direction of the inclined hole 17 is the external direction of the first mounting ring 4, and the wind direction is inclined when the air is discharged; when the plug rod 6 drives the arc plate 38 to slide, it will not conflict with the annular inclined plate 15 until the arc After the annular plate 38 enters the arc-shaped receiving groove 39 on the annular inclined plate 15, the insertion rod 6 will conflict with the annular inclined plate 15. In the process of the annular inclined plate 15 driving the sliding rod 14 to slide, the arc-shaped plate 38 and the extrusion rod 37 will be driven to slide at the same time. At this time, the extrusion rod 37 can slide along the slide rail 45, and even if the annular inclined plate 15 drives the extrusion rod 37 to slide, it will not affect the position of the extrusion plate 42. When the extrusion plate 42 squeezes the cylindrical airbag 41, it will drive the guide rod 43 to slide. The guide rod 43 can guide the extrusion plate 42 and the fourth spring 44. The fourth spring 44 will be compressed. After the first sleeve 2 and the second sleeve 3 are disassembled, the extrusion plate 42 will be automatically reset under the action of the fourth spring 44, so that the gas inside the cylindrical airbag 41 can be sucked in through the folded hose 46 to restore to the initial state.
