Description

Technical Field

[0001] This invention relates to the field of cable technology, and in particular to a leak-proof cable protection tube with a detachable connector. Background Technology

[0002] Cable protection pipes are typically composed of a rigid polyvinyl chloride (PVC) material layer, an anti-aging modified layer, and a reinforcing support layer. They are mainly used for external protection of power transmission and control lines and are widely used in the manufacture of power electronic components. Cable protection pipe joints are usually used to connect the protection pipe to the equipment.

[0003] However, the existing connector consists of a sleeve, nut, inner connector, and threaded head for connecting to the equipment. During the connection process, the nut must first be put on the protective tube, then the sleeve on the protective tube, then the inner connector is threaded to the protective tube, and finally the threaded head is connected to the nut and then connected to the equipment through the threaded head. The overall disassembly and assembly operation is cumbersome. At the same time, there will be a certain gap between the sleeve and the protective tube, and external rainwater can easily seep into the tube along the gap and corrode the cable. This not only affects the normal use of the line, but also makes the overall protection effect poor, resulting in poor protection effect. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a leak-proof cable protection pipe with a detachable connector.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a detachable leak-proof cable protection pipe, comprising a pipe body and a connector, wherein a connector mechanism is provided on the pipe body, the connector mechanism comprising a connecting component, the connecting component comprising a central pipe located at one end of the pipe body, a connecting pipe one fixed at one end of the central pipe, and a connecting pipe two rotatably connected to the other end of the central pipe, the connector mechanism further comprising an installation component one for quickly assembling and disassembling the connecting pipe one and the pipe body, an installation component two for quickly assembling and disassembling the connecting pipe two and the connector, and a sealing component for sealing.

[0006] By adopting the above technical solution, during use, the first installation component can quickly connect the pipe body and the first connecting pipe, while the second connecting pipe can be quickly installed with the connector through the second installation component. Subsequently, the sealing component can seal the pipe, reducing the possibility of rainwater leakage between the pipe body and the connector, which could affect the cable. At the same time, the whole assembly can be quickly disassembled, making it more convenient to use.

[0007] Furthermore, the surface of the first connecting pipe is provided with an installation groove for inserting the pipe body, and the surface of the first connecting pipe is provided with two sets of sliding grooves. The first mounting component includes a push block slidably connected in the sliding groove, multiple locking teeth fixed on the push block, a return spring fixed between the locking teeth and the inner wall of the sliding groove, and an elastic sleeve fixed on the first connecting pipe for blocking the push block. The inner side of the pipe body is provided with multiple sets of equally spaced toothed grooves, and the locking teeth are inserted into the inner wall of the toothed grooves.

[0008] By adopting the above technical solution, when making a connection, the push block and the locking teeth can be pushed first, and the reset spring will be stressed. Then, the tube can be inserted into the mounting groove on one surface of the connecting tube. After it is fully inserted, the push block is released, and the reset spring drives the push block and the locking teeth to reset. The locking teeth can then be engaged in the tooth groove, thereby achieving quick assembly and disassembly without having to remove each fastener individually.

[0009] Furthermore, the surface of the second connecting tube has multiple sets of sliding holes. The second mounting component includes a connecting plate that is slidably connected in the sliding holes and threadedly connected to the connecting head, a moving tube that is slidably connected in the second connecting tube, multiple control rods fixed on the moving tube, a rectangular plate fixed below the connecting plate, and a compression spring fixed between the moving tube and the inner wall of the second connecting tube. The surface of the rectangular plate has interconnected straight holes and oblique holes. The control rods slide in cooperation with the inner walls of the straight holes and oblique holes. The second mounting component also includes a control assembly for controlling the movement of the moving tube.

[0010] By adopting the above technical solution, during connection, the second connecting tube can be rotated, and then the connecting plate and the connecting head can be connected. During disassembly, the moving tube can be moved by the control component. After the control rod enters the inclined hole from the straight hole, it can drive the rectangular plate and the connecting plate to move radially along the second connecting tube, thereby realizing a quick disassembly operation. When the control component loses control of the moving tube, the compression spring drives the moving tube to reset, and the control rod enters the straight hole, thereby driving the connecting plate to reset and be positioned.

[0011] Furthermore, the surface of the second connecting tube is provided with two sets of through holes. The control component includes a push rod slidably connected in the through holes, an auxiliary spring sleeved on the push rod and fixed between the push rod and the inner wall of the through holes, and an elastic sleeve fixed on the second connecting tube to block the push rod. The pressing end of the push rod has an arc structure, and the surface of the moving tube is provided with a slope.

[0012] By adopting the above technical solution, when controlling the movement of the moving tube, the push rod can be pushed, the push rod moves in the through hole, the auxiliary spring is deformed by force, and at the same time the extrusion end of the arc structure of the push rod can extrude the inclined surface of the moving tube, thereby controlling the movement of the moving tube. After the push rod is released, the auxiliary spring drives the push rod to return to its original position.

[0013] Furthermore, the end of the connecting pipe two away from the central pipe is provided with a tapered surface.

[0014] By adopting the above technical solution, when rainwater flows through the pipe body to the conical surface of the connecting pipe, the conical surface can guide the rainwater away and reduce rainwater accumulation.

[0015] Furthermore, the surface of the connecting tube one is provided with cavity one and cavity two, and the surface of the connecting tube one is also provided with a connecting cavity for connecting cavity one and cavity two. The sealing component includes a piston ring slidably connected in cavity one, a control spring fixed between the side wall of the piston ring and the inner wall of cavity one, and a plurality of elastic airbags fixed in cavity two. The sealing component also includes a pushing assembly that controls the movement of the piston ring and locks the push block when the connecting tube two is connected to the connector.

[0016] By adopting the above technical solution, when the connecting pipe 2 is connected to the connector, the pushing component can push the piston ring to move. The piston ring squeezes the gas in the first chamber and discharges the gas into the second chamber through the connecting chamber, causing multiple elastic airbags to expand. The elastic airbags can fit tightly against the pipe body to improve the sealing effect, and at the same time, the push block is locked.

[0017] Furthermore, the sealing component also includes a plurality of flexible protrusions fixed on the surface of the elastic airbag, the longitudinal section of which is a semi-circular structure.

[0018] By adopting the above technical solution, after the elastic airbag inflates, it can drive multiple flexible protrusions on its surface. The flexible protrusions can fit into the tube body, further improving the sealing effect.

[0019] Furthermore, the surface of the pusher block is provided with a perforation, the surface of the central tube is provided with a moving hole, and the pushing assembly includes a pressing member slidably connected in the connecting tube two, a pushing member slidably connected to the inner wall of the moving hole, and two thin rods fixed between the pushing member and the piston ring. The perforation allows the thin rods and the pushing member to pass through.

[0020] By adopting the above technical solution, when the connecting tube 2 is not connected to the connector, the thin rod is located in the perforation. At this time, the push block can move normally. When the connecting tube 2 is connected to the connector, the connector can push the extrusion component, which drives the push component and the thin rod to move. The thin rod drives the piston ring to move, thereby sealing the elastic airbag. At the same time, the push component is inserted into the perforation, which can limit the push block from moving further.

[0021] Furthermore, the actuation assembly also includes two sealing gaskets fixed to the extruder for sealing between the connecting tube and the connector.

[0022] By adopting the above technical solution, when the connector is connected to the second connecting pipe, the two sealing gaskets on the surface of the extrusion part can be squeezed and adhered to the second connecting pipe and the connector respectively, thereby further improving the sealing effect.

[0023] Furthermore, the pipe body includes an outer protective layer, an intermediate protective layer disposed within the outer protective layer, and an inner protective layer disposed within the intermediate protective layer. The outer protective layer includes polyvinyl chloride, a compatibilizer, and a lubricant. The intermediate protective layer includes polyvinyl chloride, carbon fiber, an antioxidant, and a lubricant. The inner protective layer is a hot-dip galvanized steel strip.

[0024] By adopting the above technical solution, the outer layer is made of polyvinyl chloride (PVC) with compatibilizer and lubricant, which has excellent weather resistance, resistance to chemical corrosion such as acids, alkalis and salts, smooth surface and low coefficient of friction, which facilitates pipeline transportation and laying, and can effectively resist external environmental erosion and daily scratch damage. The middle layer introduces carbon fiber, antioxidant and lubricant into PVC. Carbon fiber significantly enhances the tensile strength, bending strength and impact resistance of the pipe body, greatly improves the structural rigidity and deformation resistance, while antioxidant effectively delays the thermo-oxidative aging process of polymer materials and extends the service life of the pipeline. The inner layer uses hot-dip galvanized steel strip. Relying on the electrochemical protection of the galvanized layer and the high strength of the steel strip itself, it has excellent resistance to internal corrosion, resistance to media erosion and pressure bearing capacity, while providing core structural support for the entire pipe body.

[0025] In summary, the present invention has the following beneficial effects: 1. In this application, the first installation component can be used to quickly detach and install the first connecting pipe from the pipe body, and the second installation component can be used to quickly detach and install the second connecting pipe from the connector, which facilitates quick disassembly and replacement. After the first connecting pipe is connected to the pipe body and the second connecting pipe is connected to the connector, the sealing component can seal the pipe, reducing rainwater leakage into the pipe body and improving the protection of the cable. 2. In this application, an installation component is provided. The tube body and the connecting tube are engaged by the insertion of the locking teeth and the tooth groove. With the design of the return spring, the tube body can be quickly inserted and unlocked by simply pressing the push block. After insertion, the return spring automatically drives the locking teeth to engage and position, ensuring a firm connection and facilitating quick assembly and disassembly. 3. In this application, an installation component two is provided. When connecting, the connection can be completed by rotating the connecting pipe two independently. When disassembling, it is only necessary to press the push rod to control the movement of the moving pipe. The control rod can be used to cooperate with the inclined hole and the straight hole to drive the connecting plate to retract radially, quickly disengage from the threaded connection, and achieve quick disassembly and assembly.

[0026] 4. In this application, a sealing component is provided. After the connector and the second connecting pipe are connected, the push assembly controls the piston ring to move and compress the gas in the first extrusion chamber. The gas is then sent into the second extrusion chamber through the connecting chamber to inflate the elastic airbag. In conjunction with the flexible protrusion, a 360° full wrap-around and tight fit is achieved on the pipe body, forming a multi-layer circumferential sealing barrier. This can adapt to minor deformations of the pipe body and improve the sealing adaptability. At the same time, the double sealing gaskets on the extrusion component are respectively fitted to the end faces of the second connecting pipe and the connector to form a double end face seal, further enhancing the sealing effect and effectively reducing rainwater leakage.

[0027] 5. In this application, the pusher is inserted into the through hole on the surface of the pusher block, which can restrict the movement of the pusher block and ensure the stability of the overall connection. Attached Figure Description

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] like Figure 1-14 As shown in the illustration, this application discloses a detachable, leak-proof cable protection pipe, including a pipe body 1, a connector 2, and a connector mechanism 3. The connector mechanism 3 is mounted on the pipe body 1 and includes a connecting component 31, a first mounting component 32, a second mounting component 33, and a sealing component 34. The connecting component 31 includes a central pipe 311, a first connecting pipe 312, and a second connecting pipe 313. The central pipe 311 is located at one end of the pipe body 1. The first connecting pipe 312 is fixed to one end of the central pipe 311, and the second connecting pipe 313 is rotatably connected to the other end of the central pipe 311. During use, the first mounting component 32 can quickly connect the pipe body 1 and the first connecting pipe 312, and the second connecting pipe 313 can be quickly installed to the connector 2 via the second mounting component 33. Subsequently, the sealing component 34 can seal the pipe, reducing the possibility of rainwater leakage between the pipe body 1 and the connector, which could affect the cable. The entire assembly can also be quickly disassembled, making it more convenient to use.

[0032] The surface of the connecting pipe 312 has an installation groove 4 for inserting the pipe body 1, and two sets of sliding grooves 6. The mounting component 32 is used for quick assembly and disassembly of the connecting pipe 312 and the pipe body 1. The mounting component 32 includes a push block 321, locking teeth 322, a return spring 323, and an elastic sleeve 324. The push block 321 is slidably connected within the sliding groove 6. Multiple locking teeth 322 are provided and fixed to the push block 321. The return spring 323 is fixed between the locking teeth 322 and the inner wall of the sliding groove 6. The elastic sleeve 324 is fixed to the connecting pipe 312 to block the push block 321. Multiple sets of equally spaced toothed grooves 5 are provided on the inner side of the pipe body 1, and the locking teeth 322 are inserted into the inner wall of the toothed grooves 5. When making the connection, the push block 321 and the locking tooth 322 can be pushed first, and the return spring 323 is stressed. Then, the tube body 1 can be inserted into the mounting groove 4 on the surface of the connecting tube 312. After it is fully inserted, the push block 321 is released, and the return spring 323 drives the push block 321 and the locking tooth 322 to return to their original positions. The locking tooth 322 can be engaged in the tooth groove 5, thereby achieving quick assembly and disassembly without having to remove each fastener individually.

[0033] The surface of the connecting tube 313 has multiple sets of sliding holes 7. The mounting component 33 is used for quick assembly and disassembly of the connecting tube 313 and the connector 2. The mounting component 33 includes a connecting plate 331, a moving tube 332, a control rod 333, a rectangular plate 334, a compression spring 335, and a control assembly. The connecting plate 331 is slidably connected within the sliding holes 7 and threadedly connected to the connector 2. The moving tube 332 is slidably connected within the connecting tube 313. Multiple control rods 333 are provided and fixed to the moving tube 332. The rectangular plate 334 is fixed below the connecting plate 331, and the compression spring 335 is fixed between the moving tube 332 and the inner wall of the connecting tube 313. The surface of the rectangular plate 334 has interconnected straight holes 8 and oblique holes 9. The control rod 333 slides within the straight holes 8 and oblique holes 9. During connection, the connecting tube 313 can be rotated, and then the connecting plate 331 and the connector 2 can be connected. During disassembly, the moving tube 332 can be moved by the control component. After the control rod 333 enters the inclined hole 9 from the straight hole 8, it can drive the rectangular plate 334 and the connecting plate 331 to move radially along the connecting tube 313, thereby realizing a quick disassembly operation. When the control component loses control of the moving tube 332, the compression spring 335 drives the moving tube 332 to reset, and the control rod 333 enters the straight hole 8, thereby driving the connecting plate 331 to reset and position.

[0034] Two sets of through holes 15 are provided on the surface of the connecting tube 313. A control component controls the movement of the moving tube 332. The control component includes a push rod 336, an auxiliary spring 337, and an elastic sleeve 338. The push rod 336 is slidably connected within the through hole 15. The auxiliary spring 337 is sleeved on the push rod 336 and fixed between the push rod 336 and the inner wall of the through hole 15. The elastic sleeve 338 is fixed on the connecting tube 313 to shield the push rod 336. The pressing end of the push rod 336 has an arc structure, and the surface of the moving tube 332 has a slope. When controlling the movement of the moving tube 332, the push rod 336 can be pushed, causing the push rod 336 to move within the through hole 15. The auxiliary spring 337 deforms under force, and simultaneously, the pressing end of the arc structure of the push rod 336 can press against the slope of the moving tube 332, thereby controlling the movement of the moving tube 332. After releasing the push rod 336, the auxiliary spring 337 drives the push rod 336 to return to its original position.

[0035] The end of the connecting pipe 313 furthest from the central pipe 311 is provided with a tapered surface. When rainwater flows through the pipe body 1 onto the tapered surface of the connecting pipe 313, the tapered surface can guide the rainwater away and reduce rainwater accumulation.

[0036] The surface of the connecting pipe 312 has a cavity 10 and a cavity 11, and a connecting cavity 12 for connecting the cavity 10 and the cavity 11. A sealing component 34 is used for sealing and includes a piston ring 341, a control spring 342, elastic airbags 343, and a pushing assembly. The piston ring 341 is slidably connected within the cavity 10. The control spring 342 is fixed between the side wall of the piston ring 341 and the inner wall of the cavity 10. Multiple elastic airbags 343 are provided and fixed within the cavity 11. When the connecting pipe 313 is connected to the connector 2, the pushing assembly can push the piston ring 341 to move. The piston ring 341 compresses the gas in the cavity 10 and discharges the gas into the cavity 11 through the connecting cavity 12, causing the multiple elastic airbags 343 to inflate. The elastic airbags 343 can then tightly adhere to the pipe body 1, improving the sealing effect and simultaneously locking the push block 321.

[0037] The sealing component 34 also includes multiple flexible protrusions 345. These flexible protrusions 345 are fixed to the surface of the elastic airbag 343, and their longitudinal section is semi-circular. When the elastic airbag 343 inflates, it can move the multiple flexible protrusions 345 on its surface, allowing them to conform to the tube body 1 and further improve the sealing effect.

[0038] The surface of the push block 321 has a through hole 13, and the surface of the central tube 311 has a moving hole 14. When the connecting tube 313 is connected to the connector 2, the pushing assembly controls the movement of the piston ring 341 and locks the push block 321. The pushing assembly includes a pressing member 346, a pushing member 347, and thin rods 348. The pressing member 346 is slidably connected inside the connecting tube 313. The pushing member 347 is slidably connected to the inner wall of the moving hole 14. Two thin rods 348 are provided. The two thin rods 348 are fixed between the pushing member 347 and the piston ring 341, and the through hole 13 allows the thin rods 348 and the pushing member 347 to pass through. When the connecting tube 313 is not connected to the connector 2, the thin rod 348 is located in the perforation 13. At this time, the push block 321 can move normally. When the connecting tube 313 is connected to the connector 2, the connector 2 can push the extrusion member 346. The extrusion member 346 drives the push member 347 and the thin rod 348 to move. The thin rod 348 drives the piston ring 341 to move, thereby sealing the elastic airbag 343. At the same time, the push member 347 is inserted into the perforation 13, which can limit the push block 321 from moving further.

[0039] The actuating assembly also includes two sealing gaskets 344. These two sealing gaskets 344 are fixed to the extrusion member 346 and are used to seal between the connecting tube 313 and the connector 2. When the connector 2 is connected to the connecting tube 313, the two sealing gaskets 344 on the surface of the extrusion member 346 can be pressed and adhered to the connecting tube 313 and the connector 2 respectively, further improving the sealing effect.

[0040] Pipe body 1 includes an outer protective layer, a middle protective layer, and an inner protective layer. The middle protective layer is disposed within the outer protective layer, and the inner protective layer is disposed within the middle protective layer. The outer protective layer includes polyvinyl chloride, a compatibilizer, and a lubricant. The middle protective layer includes polyvinyl chloride, carbon fiber, an antioxidant, and a lubricant. The inner protective layer is a hot-dip galvanized steel strip. The outer layer is made of polyvinyl chloride (PVC) with compatibilizers and lubricants, possessing excellent weather resistance and resistance to chemical corrosion from acids, alkalis, and salts. Its smooth surface and low coefficient of friction facilitate pipeline transportation and laying, effectively resisting external environmental erosion and daily scratches. The middle layer incorporates carbon fiber, antioxidants, and lubricants into the PVC matrix. The carbon fiber significantly enhances the tensile strength, flexural strength, and impact resistance of the pipe body 1, greatly improving structural rigidity and deformation resistance. The antioxidants effectively slow down the thermo-oxidative aging process of the polymer material, extending the service life of the pipeline. The inner layer uses hot-dip galvanized steel strip. Relying on the electrochemical protection of the galvanized layer and the high strength of the steel strip itself, it possesses excellent resistance to internal corrosion, media erosion, and pressure bearing capacity, while providing core structural support for the entire pipe body 1.

[0041] The working principle of the detachable leak-proof cable protection pipe in this embodiment is as follows: When connecting the connecting pipe 312 to the pipe body 1, the push block 321 and the locking tooth 322 can be pushed first, and the return spring 323 is stressed. Then, the pipe body 1 can be inserted into the mounting groove 4 on the surface of the connecting pipe 312. After it is fully inserted, the push block 321 is released, and the return spring 323 drives the push block 321 and the locking tooth 322 to return to their original positions. The locking tooth 322 can then engage in the tooth groove 5, thereby achieving quick installation. Subsequent push... The movable push block 321 allows for quick disassembly, eliminating the need to remove fasteners one by one as in traditional methods. When connecting the second connecting pipe 313 to the connecting head 2, simply rotate the second connecting pipe 313. The second connecting pipe 313, along with multiple connecting plates 331, can then be threaded into the connecting head 2. Simultaneously, the connecting head 2 pushes the pressing component 346, which in turn moves the pushing component 347 and the thin rod 348. The thin rod 348 synchronously moves the piston ring 341, controlling the force on the spring 342 and the piston. The gas in the compression chamber 10 is compressed by ring 341 and discharged into the second chamber 11 through the connecting chamber 12, causing multiple elastic airbags 343 to inflate. The elastic airbags 343, together with multiple flexible protrusions 345, can fit tightly against the tube body 1, sealing the connection tube 2 313 with the tube body 1. At the same time, the connector 2 and the connection tube 2 313 are both pressed against the sealing gasket 344, reducing rainwater leakage. Meanwhile, after the pusher 347 enters the perforation 13, it can lock the pusher block 321. The tube cannot be moved. When it is necessary to disassemble the connecting tube 313 and the connector 2, simply push the push rod 336. The push rod 336 moves in the through hole 15, and the auxiliary spring 337 deforms under force. At the same time, the extrusion end of the arc structure of the push rod 336 can extrude the inclined surface of the moving tube 332, thereby controlling the movement of the moving tube 332. After the control rod 333 enters the inclined hole 9 from the straight hole 8, it can drive the rectangular plate 334 and the connecting plate 331 to move radially along the connecting tube 313, thereby realizing a quick disassembly operation.
