Description

Technical Field

[0001] The utility model relates to the field of electrical facilities, in particular to an electrical automation wire protection device. Background Art

[0002] During the operation of electrical automation equipment, the protection and reasonable layout of equipment cables are crucial to the stability, safety and maintenance convenience of the equipment. The outlets of existing cable sheaths are mostly fixed structures, and it is difficult to adjust the outlet position after the cables are inserted. When the equipment layout changes or the cable route is optimized, the cables need to be re-threaded, which is not only cumbersome to operate but also increases maintenance costs. Fixed outlets cannot meet the needs of dynamic layout, resulting in excessive cable exposure or excessive bending. In addition, existing sheaths are usually of a single length and lack a quick-extend connection structure. In large-scale automated production lines, cables need to cover long distances. At the same time, traditional cable harnesses have insufficient clamping force on the cables, and they are prone to loosening under long-term use or vibration environments, resulting in changes in the actual length of the cables inserted into the sheath, causing the sheath's protective function for the cables to fail and making it inconvenient to use. Utility Model Content

[0003] The purpose of this utility model is to provide an electrical automation wire protection device in order to solve the above problems, which solves the problems of fixed sheath outlet position, inconvenient length adjustment and poor connection stability of existing sheath, ensures that the cable protection of electrical automation equipment is more efficient, flexible and stable, and improves the assembly efficiency and maintenance convenience of the equipment. See the following for details.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] The utility model provides an electrical automation wire protection device, comprising a wire tube and a wire body inserted into the wire tube, a wire harness seat is provided on the outside of the wire tube for guiding the wire body to pass through the wire tube, and a socket pipe and a movable joint are respectively provided at both ends of the wire tube, and the movable joint is used to connect the socket pipe and the wire tube to form an extended structure;

[0006] A wire outlet groove for installing a wire harness seat is provided on the outside of the wire tube. The wire harness seat includes an inner cylinder extending into the wire tube along the wire outlet groove. An inner edge for pressing against the inner wall of the wire tube is fixed to the inner end portion of the inner cylinder. An outer cylinder is threadedly engaged with an outer cylinder on the outer side of the inner cylinder. An outer edge pressing against the outer wall of the wire tube is fixed to the outer end portion of the outer cylinder. The outer edge and the inner edge cooperate to form a clamping mechanism that supports the wire harness seat as a whole and clamps it to any position in the wire outlet groove on the wire tube. The wire body passes through the wire tube along the inner cylinder.

[0007] The outer thread of the inner tube and the outer thread of the inner tube are screwed together to loosen the inner edge and the outer edge so that they are separated from each other, thereby releasing the pressing effect of the inner tube and the outer tube on the side walls of the wire tube on both sides of the wire outlet trough. At this time, the wire harness seat can be slid along the length direction of the wire outlet trough to achieve position adjustment, and the tightening constraint state of the multiple groups of wire clamping blocks on the inner edge of the wire body on the wire body disappears simultaneously, so as to facilitate the adjustment of the outlet position of the wire body and the wire harness seat. After the wire harness seat is adjusted to the set position of the wire outlet trough, the inner tube is tightened under the support of the outer tube to clamp the inner edge and the outer edge to the side walls of the wire tube on both sides of the wire outlet trough, and the pressing state of the multiple groups of wire clamping blocks on the inner edge of the wire body is maintained, thereby locking the position of the wire harness seat and completing the position locking action of the wire body in the wire harness seat at the same time; when multiple wire tubes need to be connected in sequence to extend the binding distance of the wire body, the combined ring is pushed to make it close to the installation position. The locking block of the spring clip on the socket is engaged in the locking groove, and the locking block of the spring clip on the socket is engaged in the locked groove. Then, the locking block of the spring clip is released to reset. At this time, the locking block is sleeved on the outside of the socket, and the locking block of the spring clip is restricted by the locking block to be disengaged from the locking groove, thereby completing the connection and combination process of the adjacent sockets.

At this time, the socket pipe of the adjacent socket pipe is sleeved onto the outside of the core barrel to lock the locking block of the spring clip on the socket pipe into the locked groove in the open state. Then, the combination ring is released to reset it. At this time, the combination ring is sleeved on the outside of the socket pipe, and the locking block of the spring clip is restricted by the combination ring to be disengaged from the locking groove, thereby completing the connection and combination process of the adjacent sockets. When the socket pipe needs to be cut to change the length according to actual needs, the installation ring is pushed toward the combination ring to separate the installation ring from the socket pipe end outside the core barrel to release the tightening state of the installation ring on the socket pipe end. Then, the socket pipe of the adjacent socket pipe is sleeved

[0008] Preferably, the inner edge is a trumpet-shaped structure that fits the inner wall of the wire tube, and the outer end of the inner tube protrudes outward to fix an operating ring. The operating ring, the inner tube and one side of the inner edge are penetrated by an internal groove, which is used to guide the wire body to be inserted into the inner tube.

[0009] Preferably, the outer cylinder and one side of the outer edge are provided with an outer card slot connected to the inner card slot. When the outer cylinder is rotated under the support of the inner cylinder until the inner card slot is aligned with the outer card slot, the outer card slot and the inner card slot form a wire clamping channel that guides the wire body to be clamped into the wire harness seat from the side.

[0010] Preferably, a plurality of groups of wire clamping blocks are arranged around the side of the inner edge away from the inner tube, the wire clamping blocks are made of rubber, and are used to clamp and lock the wire body stuck in the inner edge.

[0011] Preferably, the bell pipe is a hard pipe, and the bell pipe is fixedly connected to the wire pipe. A plurality of groups of movable grooves are arranged around the outer circumference of the middle section of the bell pipe, and elastically bendable spring pieces are fixed in the plurality of movable grooves. A locking block is fixed on the side of the spring piece facing the inner wall of the bell pipe.

[0012] Preferably, the locking block is a wedge-shaped block structure, and the movable joint includes a core tube which is sleeved on the inner side of one end of the wire tube away from the socket pipe, and a plurality of locking grooves are arranged around the middle section of the core tube, and the locking grooves correspond to the locking block and can be snap-fitted with the locking block.

[0013] Preferably, the wire tube includes annular ridges evenly distributed along its length direction, and a convex ring is fixed to the outside of the core tube near one end of the wire tube to support and lock the ridges, and a guide portion extending along its axial direction is fixed to the outside of the core tube, and the guide portion is a convex block structure, and limit blocks are fixed at both ends of the outside of the guide portion.

[0014] Preferably, the end of the socket pipe is provided with a guide groove that is snap-fitted with the guide part, and the outer side of the guide part is provided with a mounting ring and a combination ring that are laterally correspondingly distributed, and a spring is provided between the mounting ring and the combination ring.

[0015] The beneficial effects are: 1. The cable holder of the utility model can slide along the length direction of the cable outlet trough of the wire tube, and the relative position of the inner edge and the outer edge can be adjusted by the threaded cooperation of the inner tube and the outer tube, so that the cable holder can be clamped and locked to different positions in the length direction of the cable outlet trough, which is suitable for various wiring requirements. Specifically, the inner edge and the outer edge clamp the wire tube, and the rubber wire clamping block clamps the wire body to prevent the wire body from loosening after passing through the cable holder, and buffers the friction between the wire body vibration and the cable holder, which is suitable for cables of multiple diameters, improves the protection stability in a vibration environment, and extends the life of the cable.

[0016] 2. The movable joint and the socket are quickly connected through a locking block, locking groove, and a spring-loaded combination ring. No installation tools are required, which improves the assembly efficiency of large electrical production lines.

[0030] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0031] See also Figures 1-9 As shown, the utility model provides an electrical automation wire protection device, comprising a wire tube 1 and a wire body 2 inserted into the wire tube 1, the wire body 2 is a cable that needs to be bundled and protected, a wire harness seat 3 is provided on the outside of the wire tube 1 to guide the wire body 2 to pass through the wire tube 1, and a socket pipe 4 and a movable joint 5 are respectively provided at both ends of the wire tube 1, and the movable joint 5 is used to connect the socket pipe 4 with the wire tube 1 to form an extended structure;

[0032] A wire outlet groove 101 for installing a wire harness holder 3 is provided on the outside of the wire pipe 1. The wire harness holder 3 includes an inner cylinder 301 extending into the interior of the wire pipe 1 along the wire outlet groove 101. An inner edge 302 for pressing against the inner wall of the wire pipe 1 is fixed to the inner end of the inner cylinder 301. An outer cylinder 305 is threadedly engaged with the outer end of the inner cylinder 301. An outer edge 306 pressing against the outer wall of the wire pipe 1 is fixed to the outer end of the outer cylinder 305. The outer edge 306 cooperates with the inner edge 302 to form a clamping mechanism that supports the wire harness holder 3 as a whole and clamps it to any position in the wire outlet groove 101 on the wire pipe 1. The wire body 2 passes through the wire pipe 1 along the inner cylinder 301.

[0033] As an optional embodiment, the inner edge 302 is a trumpet-shaped structure that fits the inner wall of the wire tube 1, which is used to enhance the fit to the inner wall and improve the clamping stability. The outer end of the inner cylinder 301 protrudes outward and is fixed with an operating ring 303. The operating ring 303, the inner cylinder 301 and one side of the inner edge 302 are penetrated by an inner groove 304. The inner groove 304 is used to guide the wire body 2 to be clamped into the inner cylinder 301. With this arrangement, the wire body 2 can be quickly clamped into the inner cylinder 301 through the guiding effect of the inner groove 304, simplifying the threading operation;

[0034] The outer cylinder 305 and one side of the outer edge 306 are provided with an outer card slot 307 connected to the inner card slot 304. When the outer cylinder 305 is rotated under the support of the inner cylinder 301 until the inner card slot 304 is aligned with the outer card slot 307, the outer card slot 307 and the inner card slot 304 form a wire clamping channel that guides the wire body 2 to be clamped into the wire harness seat 3 from the side, which is used for the side quick installation of the wire body 2. Such a setting can avoid the tedious insertion of the wire body 2 from the end of the wire tube 1 as a whole, and is suitable for the scene of multiple wire bodies 2 branching out. The opening and closing states of the wire clamping channel can be switched by rotating the outer cylinder 305, and the wire outlet method can be flexibly controlled.

[0035] A plurality of groups of wire clamping blocks 308 are arranged around the inner edge 302 away from the inner tube 301. The wire clamping blocks 308 are made of rubber and are used to clamp and lock the wire body 2 inserted into the inner edge 302. This arrangement utilizes the elastic deformation of the rubber to tightly wrap the wire body 2, preventing the wire body 2 from loosening and shifting, and buffering the damage to the cable caused by external vibration. At the same time, it is adaptable to wire bodies 2 of different diameters, thereby improving the versatility of the device.

[0036] The socket pipe 4 is a hard pipe, which is used to provide rigid support during connection, ensuring that the socket pipe 4 does not deform during the sleeve connection with the core tube 501, maintaining the precise fit between the locking block 403 and the locking groove 504, and the socket pipe 4 is fixedly connected to the wire pipe 1. A plurality of groups of movable grooves 401 are arranged around the outer circumference of the middle section of the socket pipe 4, and elastically bendable spring pieces 402 are fixed in the plurality of movable grooves 401. A locking block 403 is fixed on the side of the spring piece 402 facing the inner wall of the socket pipe 4. The locking block 403 is a wedge-shaped block structure, which is used to insert the socket pipe 4 When the core barrel 501 is engaged, the locking block 403 is automatically engaged with the locking groove 504 through the guiding effect of the wedge-shaped inclined surface, achieving a quick connection without the need for additional tools, thereby improving assembly efficiency. The movable joint 5 includes a core barrel 501 sleeved on the inner side of the end of the wire tube 1 away from the socket pipe 4, and a plurality of locking grooves 504 are arranged around the middle section of the core barrel 501. The locking grooves 504 correspond to the locking blocks 403 and can be engaged with the locking blocks 403 to form a mechanical lock between the socket pipe 4 and the core barrel 501, ensuring a stable connection and preventing the joint from falling off when the cable is pulled;

[0037] The wire tube 1 includes annular ridges 102 evenly distributed along its length. A protruding ring 502 is fixed to the outside of the core tube 501 near one end of the wire tube 1 to support and lock the protruding ridges 102. The protruding ring 502 is used to engage with the protruding ridges 102 to enhance the vibration resistance of the connection between the wire tube 1 and the core tube 501, improve the mechanical strength of the connection structure, and adapt to complex working conditions. A guide portion 503 extending along the axial direction is fixed to the outside of the core tube 501. The guide portion 503 is a convex block structure, and limit blocks 503a are fixed to both ends of the outside of the guide portion 503.

[0038] The end of the socket pipe 4 is provided with a guide groove 404 that is locked into the guide part 503. The outside of the guide part 503 is provided with a mounting ring 505 and a combination ring 506 that are distributed correspondingly in the transverse direction. A spring 507 is provided between the mounting ring 505 and the combination ring 506 to provide an elastic reset force so that the combination ring 506 automatically resets after the socket pipe 4 is installed, blocks the locking groove 504, prevents the locking block 403 from accidentally falling out, and ensures the long-term stability of the connection. The mounting ring 505 is provided on the outside of the end of the wire pipe 1. The mounting ring 505 is used to maintain the connection state between the end of the wire pipe 1 and the end of the core tube 501. The combination ring 506 is provided on the outside of the locking groove 504. The combination ring 506 is used to maintain the locking block 403 in the locking groove 504 after the socket pipe 4 and the core tube 501 are sleeved.

[0039] When the clamping block 308 on the inner wall of the clamping block 301 is in the closed position, the clamping block 308 on the inner wall of the clamping block 301 is in the closed position, and the clamping block 308 on the inner wall of the clamping block 301 is in the closed position. The locking groove 504 is blocked by the combination ring 506, and the locking groove 504 is kept in the open state. At this time, the socket pipe 4 of the adjacent wire pipe 1 is sleeved to the outside of the core barrel 501 to fit the locking block 403 of the spring piece 402 on the socket pipe 4 into the open locking groove 504, and then the combination ring 506 is released to reset it. At this time, the combination ring 506 is sleeved to the outside of the socket pipe 4, and the combination ring 506 restricts the locking block 403 of the spring piece 402 from escaping from the locking groove 504 to complete the connection and combination process of the adjacent wire pipes 1 (such as Figure 9 shown);

[0040] When the length of the wire tube 1 needs to be changed by cutting it according to actual needs, the mounting ring 505 is pushed toward the combination ring 506 to separate the mounting ring 505 from the end of the wire tube 1 outside the core barrel 501, thereby releasing the tightening state of the mounting ring 505 on the end of the wire tube 1. Then, the end of the wire tube 1 is pulled out of the core barrel 501 and the wire tube 1 is cut to the set use length. At this time, the end of the wire tube 1 is put on the end of the core barrel 501 again, and the mounting ring 505 is loosened and pushed back by the spring 507. Then, the mounting ring 505 is clamped on the outside of the wire tube 1 again, and the ridge 102 of the wire tube 1 is engaged with the convex ring 502 of the core barrel 501 to ensure that the movable joint 5 can be quickly installed when the wire tube 1 is cut to different lengths.

[0041] The cable holder 3 can slide along the length direction of the cable outlet trough 101 of the cable tube 1, and the relative position of the inner edge 302 and the outer edge 306 can be adjusted by the threaded cooperation between the inner tube 301 and the outer tube 305, so that the cable holder 3 can be clamped and locked to different positions in the length direction of the cable outlet trough 101 to adapt to various wiring requirements. Specifically, the inner edge 302 and the outer edge 306 clamp the cable tube 1, and the rubber clamping block 308 clamps the wire body 2 to prevent the wire body 2 from loosening after passing through the cable holder 3, and buffers the friction between the vibration of the wire body 2 and the cable holder 3, adapting to cables of multiple diameters, improving the protection stability in a vibration environment, and extending the life of the cable.

[0042] The movable joint 5 and the socket pipe 4 are quickly connected by the combination ring 506 supported by the locking block 403, the locking groove 504 and the spring 507. No installation tools are required, which improves the assembly efficiency of large-scale electrical production lines. After the wire tube 1 is cut according to the actual length of the wire body 2 in the area, the ridge 102 of the wire tube 1 is engaged with the convex ring 502 of the core barrel 501, and then tightened by the installation ring 505, it can flexibly adapt to the length adjustment of equipment modification.

[0043] The inner and outer card slots 307 of the cable holder 3 form a cable clamping channel, which can support the wire body 2 to be quickly clamped from the side, realize the branching of multiple cables with the same sheath, avoid entanglement problems, simplify the wiring maintenance work of multiple lines, improve the neatness and maintenance convenience of wiring, and reduce the risk of cable wear.
