[0001] The embodiment of the present application relates to the technical field of cable production, in particular to a cable deviation adjusting device. BACKGROUND

[0002] The cable is a wire product used to transmit power information and realize electromagnetic energy conversion, which can be applied to power, communication, building, industry, transportation and other fields. The cable is generally manufactured through wire drawing, twisting, coating and other auxiliary processes.

[0003] The coating process of the cable includes an extrusion process, and the eccentricity of the extrusion layer is an important evaluation index of the quality of the cable. The traditional extrusion configuration usually includes a positioning frame, an extruder and a machine head, and the positioning frame is movable relative to the machine head. In production, the positioning frame is fixed at the wire inlet of the machine head, the cable passes through the positioning frame into the machine head, the extruder operates, and the extrusion process is completed.

[0004] However, the positioning frame in this design has poor fixing precision, which easily causes the eccentricity of the extrusion layer to be large, affecting the quality of the cable. SUMMARY

[0005] Therefore, the embodiment of the present application provides a cable deviation adjusting device to improve the positioning precision of the cable, reduce the eccentricity of the extrusion layer and improve the quality of the cable.

[0006] To achieve the above-mentioned purpose, the embodiment of the present application provides a cable deviation adjusting device, which adopts the following technical scheme:

[0007] The cable deviation adjusting device provided by the embodiment of the present application is installed at the wire inlet of the machine head and includes a base and an adjusting assembly, and the adjusting assembly includes:

[0008] A fixed part is fixed to the base;

[0009] A movable part is rotationally connected to the fixed part;

[0010] A plurality of positioning members collectively define a positioning channel for the cable to pass through, and two ends of the positioning member are respectively pivotally connected to the fixed part and the movable part;

[0011] The positioning channel is coaxially arranged with the wire inlet.

[0012] In a possible implementation, the projections of the plurality of positioning members in the reference surface are distributed along the circumference of the positioning channel, and the projections of any two adjacent positioning members along the circumference coincide, so that the projection of the positioning channel in the reference surface forms a polygon, and one side of the projection of each positioning member constitutes one side edge of the polygon,

[0013] The reference plane is perpendicular to the axis of the positioning channel.

[0014] In a possible implementation, any of the positioning members abuts against the cable.

[0015] In a possible implementation, the fixed part is formed as a fixed ring, and the movable part is formed as a movable ring, the movable ring being rotatably arranged on the inner side or the outer side of the fixed ring,

[0016] The projections of the plurality of fixed rings in the reference plane are on the inner side or the outer side of the projection of the movable ring in the reference plane.

[0017] The movable ring is provided with a first connecting column, and the fixed ring is provided with a second connecting column, the first connecting column and the second connecting column both extend along the axial direction of the positioning channel.

[0018] The two ends of the positioning member are respectively pivotally connected with the first connecting column and the second connecting column.

[0019] In a possible implementation, the positioning member includes a roller and a linkage mechanism.

[0020] The linkage mechanism includes a first linkage and a second linkage, the first end of the first linkage is pivotally connected with the first connecting column, the first end of the second linkage is pivotally connected with the second connecting column, the second end of the first linkage and the second end of the second linkage are pivotally connected, and the roller is sleeved on the first linkage and rotatable relative to the first linkage.

[0021] The rollers of the plurality of positioning members jointly define the positioning channel.

[0022] In a possible implementation, the plurality of positioning members are located on at least one side of the fixed part along the axial direction of the positioning channel.

[0023] In a possible implementation, the movable part is provided with an operating member, the operating member being configured to drive the movable part to rotate relative to the fixed part.

[0024] In a possible implementation, the fixed part is provided with a movable channel penetrating in the radial direction, the movable channel extending along the circumferential direction of the fixed part.

[0025] The operating member is arranged through the movable channel and slides in the movable channel.

[0026] In a possible implementation, the cable deviation adjusting device further includes a locking member, the locking member being provided with a locking position and an unlocking position.

[0027] Wherein, in the locking position, the movable part and the fixed part are locked together, and in the unlocking position, the movable part is adapted to rotate relative to the fixed part.

[0028] In a possible implementation, the base comprises a support ring and a support column, and the support ring and the fixed part are fixedly arranged at two ends of the support column respectively, and the support ring defines a through channel arranged opposite to the positioning channel.

[0029] The cable deviation adjusting device provided by the embodiment of the application can limit the axis of the cable to be collinear with the axis of the positioning channel and the wire inlet by adjusting the angle of the movable part, i.e., adjusting the position of the positioning member, thereby improving the precision of the cable when passing through the wire inlet of the machine head and helping to achieve the preset eccentricity target. Specifically, when the movable part rotates, the movable part drives the positioning member pivotally connected thereto to move, and the movement of the positioning member changes the size of the positioning channel, thereby pushing the axis of the cable to be finely adjusted to be collinear with the axis of the positioning channel. In this way, the coaxiality between the cable and the wire inlet of the machine head can be ensured, and the stability and accuracy of the cable during the passing process can be ensured.

[0030] It can be seen that the design improves the precision of the cable passing through the wire inlet of the machine head and also helps to reduce the problem of excessive eccentricity of the extruded layer caused by inaccurate positioning. By flexibly adjusting the angle of the movable part and the position of the positioning member, the stable eccentricity of the cable during the extrusion process can be ensured, and the quality and reliability of the cable can be improved.

[0031] In addition, by adjusting the angle of the movable part, the size of the positioning channel can also be flexibly adjusted to adapt to cables of different specifications and types. In addition, the cable deviation adjusting device of the application also reduces the frequent disassembly and assembly operation of the traditional device, thereby avoiding the problems of slow fixing speed and poor fixing effect caused by frequent disassembly and assembly, and improving the cable manufacturing efficiency.

DETAILED DESCRIPTION

[0043] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, the same numbers are used to indicate the same elements throughout the several views. The following detailed description is not intended to represent that the embodiments in accordance with the present application cannot be practiced with other alternative embodiments being used. Instead, it is described with reference to a particular embodiment as an example of the embodiments in accordance with the present application as detailed in the attached claims.

[0044] Secondly, it should be noted that in the description of the embodiments of the present application, the terms indicating the direction or positional relationship such as "inner", "outer", etc. are based on the direction or positional relationship shown in the drawings, which is merely for the convenience of description, and does not indicate or imply that the device or member must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0045] ​In addition, it also needs to be explained that, in the description of the embodiments of the present application, unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0046] Cables are wire products used to transmit power information and realize electromagnetic energy conversion, which can be applied to power, communication, construction, industry, transportation and other fields.

[0047] Cables are generally manufactured through drawing, stranding, coating and other auxiliary processes.

[0048] Among them, drawing is the first process of cable manufacturing, and is also the process of processing conductor raw materials into single wires of required specifications. Specifically, the conductor raw material is fed into the drawing machine, and the cross-sectional area is compressed through the drawing action of the die to obtain the required cross-sectional area shape and size.

[0049] Stranding is the process of stranding multiple single wires together according to a certain direction and rule to form a wire core that meets the requirements of softness and strength. Specifically, multiple single wires are fed into the stranding machine and stranding is performed according to the specified stranding direction and stranding pitch. For some special cables, such as power cables, tight pressing treatment needs to be performed during stranding to improve the filling factor and conductivity of the conductor.

[0050] Coating is the process of coating insulating materials, sheath materials, etc. on the outside of the conductor or wire core to form the insulating layer and protective layer of the cable. Coating includes insulation extrusion (i.e. extrusion process), inner sheath coating, armor, and outer sheath coating.

[0051] Specifically, insulation extrusion is to heat the extruder to an appropriate temperature, melt the insulation material such as plastic, rubber, etc. and extrude it to coat on the outside of the conductor or wire core; inner sheath coating is to coat a layer of inner sheath on the outside of the insulating layer to protect the insulating layer from being damaged by the armor, the inner sheath can be coated by extrusion or wrapping, and the material can include polyethylene, polyvinyl chloride, etc.; armor is to add an armor layer on the outside of the inner sheath for cables that need to withstand certain pressure or tension, such as underground cables or underwater cables, the armor layer can use steel belts, steel wires, etc.; outer sheath coating is to coat an outer sheath on the outside of the armor to protect the cable from environmental factors such as moisture, corrosion, etc., the outer sheath can be coated by extrusion, and the material can include polyethylene, polyvinyl chloride, chlorinated polyethylene, etc.

[0052] It can be seen that the sheathing process of the cable includes an extrusion process, and the eccentricity of the extrusion layer is an important evaluation index of the mass of the cable. The traditional extrusion configuration usually includes a positioning frame, an extruder, a head, etc. The positioning frame is movable relative to the head. In production, the positioning frame is fixed at the wire inlet of the head, the cable passes through the positioning frame and enters the head, the extruder operates, and the extrusion process is completed.

[0053] It can be understood that the size of the pass-through of the positioning frame is constant (the pass-through is generally designed as X-shaped, well-shaped, etc.), and when the positioning frame is fixed on the head, the position of the pass-through is fixed, which means that the position of the pass-through will be re-fixed every time the positioning frame is fixed.

[0054] Therefore, the fixing precision of the positioning frame in this design is poor, which easily causes the eccentricity of the extrusion layer to be large, affecting the quality of the cable. In addition, this design also has the disadvantages of slow fixing speed and poor fixing effect caused by frequent disassembly and assembly of the positioning frame.

[0055] To solve the above problems, the cable eccentricity adjusting device provided by the embodiments of the present application can limit the axis of the cable to be collinear with the axis of the positioning channel and the wire inlet by adjusting the angle of the movable part, i.e. adjusting the position of the positioning part, thereby improving the precision of the cable when passing through the wire inlet of the head, and helping to achieve the preset eccentricity target. Specifically, when the movable part rotates, the movable part will move the positioning part pivotally connected thereto, and the movement of the positioning part will change the size of the positioning channel, thereby pushing the axis of the cable to be fine-tuned to be collinear with the axis of the positioning channel. In this way, the coaxiality between the cable and the wire inlet of the head can be ensured, and the stability and accuracy of the cable during the passing process can be ensured.

[0056] It can be seen that this design improves the precision of the cable passing through the wire inlet of the head, and also helps to reduce the problem of excessive eccentricity of the extrusion layer caused by inaccurate positioning. By flexibly adjusting the angle of the movable part and the position of the positioning part, the stable eccentricity of the cable during the extrusion process can be ensured, and the quality and reliability of the cable can be improved.

[0057] In addition, by adjusting the angle of the movable part, the size of the positioning channel can also be flexibly adjusted to adapt to different specifications and types of cables. In addition, the cable eccentricity adjusting device of the present application also reduces the frequent disassembly and assembly operation of the traditional device, thereby avoiding the problems of slow fixing speed and poor fixing effect caused by frequent disassembly and assembly, and improving the cable production efficiency.

[0058] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail in the following specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0059] Referring toFigures 1 to 3 As shown, the cable biasing device provided by the embodiment of the present application is used to be installed at the wire inlet of the head.

[0060] The cable biasing device can include a base 100 and an adjusting assembly 200, wherein the base 100 is a supporting structure of the cable biasing device, which ensures the stability and facilitates the installation of the device, and the base 100 is used to be installed on the head (such as a sheath, an insulation extrusion part).

[0061] Optionally, the connection mode of the base 100 and the head can be welding, threaded connection, clamping, etc. The cable biasing device of the present application can be used for extrusion operation of different specifications of wire cores or conductors, and the eccentric adjustment effect cooperates with the operation of the extruder to ensure the quality and reliability of the cable.

[0062] It can be understood that, in actual use, the base 100 is fixed on the head, which can ensure that the positioning channel 300 is coaxial with the wire inlet, and when the extrusion operation of different specifications of wire cores or conductors is performed subsequently, the position of the positioning member 230 only needs to be adjusted to change the size of the positioning channel 300, so that the adaptation can be realized, the frequent disassembly and assembly operation of the traditional device for adapting different specifications of wire cores or conductors is reduced, and then the problems of slow fixing speed and poor fixing effect caused by frequent disassembly and assembly are reduced.

[0063] The adjusting assembly 200 includes a fixed part 210, a movable part 220 and a plurality of positioning members 230. Optionally, the materials of the fixed part 210 and the movable part 220 and the material of the supporting part of the positioning member 230 can be 45 steel, so as to ensure sufficient strength and durability, and facilitate processing and connection.

[0064] Specifically, the fixed part 210 is fixed to the base 100, and is used as the supporting and rotating center of the movable part 220.

[0065] The movable part 220 is rotationally connected to the fixed part 210, so that it can rotate within a certain range relative to the fixed part 210, so as to adjust the position, angle, etc. of the positioning channel 300.

[0066] The plurality of positioning members 230 collectively define a positioning channel 300 for the cable to pass through, and the two ends of the positioning member 230 are respectively pivotally connected to the fixed part 210 and the movable part 220, so that when the movable part 220 rotates, the positioning member 230 will move, so that the shape and position of the positioning channel 300 can be fine-tuned by adjusting the movement of the movable part 220.

[0067] The positioning channel 300 is configured to be coaxially arranged with the wire inlet, so that when the cable passes through the positioning channel 300, the axis line thereof is consistent with the axis line of the wire inlet of the head, which ensures the accuracy and stability of the cable during the passing process.

[0068] It can be understood that by adjusting the angle of the movable part 220, that is, adjusting the position of the positioning member 230, the axis of the cable can be limited to be collinear with the axis of the positioning channel 300 and the wire inlet, thereby improving the precision of the cable when passing through the wire inlet of the machine head, and helping to achieve the preset eccentricity target. Specifically, when the movable part 220 rotates, the movable part 220 will move the positioning member 230 pivotally connected thereto, and the movement of the positioning member 230 will change the size of the positioning channel 300, thereby pushing the axis of the cable to fine-tune to be collinear with the axis of the positioning channel 300. In this way, the coaxiality between the cable and the wire inlet of the machine head can be ensured, thereby ensuring the stability and accuracy of the cable during the passing process.

[0069] It can be seen that this design improves the precision of the cable passing through the wire inlet of the machine head, and also helps to reduce the problem of excessive eccentricity of the extruded layer caused by inaccurate positioning. By flexibly adjusting the angle of the movable part 220 and the position of the positioning member 230, the stable eccentricity of the cable during the extrusion process can be ensured, thereby improving the quality and reliability of the cable.

[0070] In addition, by adjusting the angle of the movable part 220, the size of the positioning channel 300 can also be flexibly adjusted to adapt to different specifications and types of cables.

[0071] In addition, the cable deviation adjusting device of the present application also reduces the frequent disassembly and assembly operation of the traditional device, thereby avoiding the problems of slow fixing speed and poor fixing effect caused by frequent disassembly and assembly, and improving the cable production efficiency.

[0072] In some embodiments, in combination with Figure 1 The base 100 includes a support ring 110 and a support column 120, and the support ring 110 and the fixed part 210 are fixedly arranged at both ends of the support column 120, respectively. The support ring 110 defines a through channel 111 arranged opposite to the positioning channel 300. In this way, the cable can enter from one side of the support ring 110, pass through the through channel 111, and then pass out of the positioning channel 300, realizing continuous arrangement and deviation adjustment of the cable.

[0073] The support column 120 is a support component connecting the support ring 110 and the fixed part 210, which can be designed as a straight column structure for providing vertical support. Optionally, a plurality of support columns 120 can be designed, which are evenly distributed on the support ring 110. For example, the support column 120 can be designed with four.

[0074] Optionally, the cross-sectional shape of the support column 120 can be circular, square or other shapes to provide sufficient strength and stability.

[0075] Optionally, in combination with Figure 1The support column 120 can be provided with a plurality of lightening holes 121, which are evenly distributed along the length direction of the support column 120. In this way, the consistency of the lightening effect can be ensured, the lightening of the support column 120 is realized, and the structural strength of the support column 120 is ensured.

[0076] Optionally, in combination with Figures 1 to 4 The lightening holes 121 can also be designed on the support ring 110, the fixed part 210, and the movable part 220, as long as the structural strength of each component is realized, which is not limited herein.

[0077] It can be seen that the design of the support ring 110 and the support column 120 provides a support basis for the cable deviation adjusting device, ensures the stability and reliability of the device during operation, and in addition, the relative arrangement of the through channel 111 and the positioning channel 300 enables the cable to smoothly pass through the base 100 and be adjusted, meeting the needs of different cable arrangements and deviation adjustments.

[0078] In some embodiments, in combination with Figures 1 to 3 The projections of the plurality of positioning members 230 in the reference plane are distributed along the circumference of the positioning channel 300. In this way, it can be understood that the plurality of positioning members 230 are circumferentially distributed around the axis of the positioning channel 300. For example, the shape surrounded by the plurality of positioning members 230 can be circular, polygonal, etc. This distribution mode helps to constrain the cable from multiple directions, ensuring that the cable can remain stable when passing through the positioning channel 300.

[0079] The projections of any two adjacent positioning members 230 along the circumference partially overlap. In this way, the gap between the positioning members 230 is minimized, thereby enhancing the overall strength and stability of the positioning channel 300. In addition, the overlapping part can also provide additional support to prevent the cable from deviating from the preset axis due to stress during the passing process.

[0080] The partially overlapping design of adjacent positioning members 230 causes the projection of the positioning channel 300 in the reference plane to form a polygon, and one side of the projection of each positioning member 230 constitutes one side edge of the polygon. The reference plane is perpendicular to the axis of the positioning channel 300. In this way, it can be understood that the polygonal structure increases the rigidity of the positioning channel 300 and also enables the positioning channel 300 to better adapt to different specifications and types of cables.

[0081] It can be seen that the positioning channel 300 of the polygonal structure provides stronger stability and support force, helps to avoid the possible deviation or distortion of the cable during the passing process, enhances the stability of the device and the constraint ability to the cable axis, and improves the precision and stability of the cable passing through the wire inlet of the head. In addition, through the layout design of the positioning member 230 and the projection overlap design, the high precision and stability of the cable during passing through the positioning channel 300 are ensured, which helps to achieve the preset eccentricity target and ensure the cable production quality and efficiency.

[0082] Optionally, the number of positioning members 230 can be a, wherein a and n are integers, and a is not less than 3. It can be understood that a is a single positioning member 230, and the number of a can be 3, 4, 5, etc., that is, the number of positioning members 230 can be 3, 4, 5, etc. The specific number can be selectively designed according to actual use requirements, as long as multiple positioning members 230 can jointly define a positioning channel 300 with a polygonal projection in the reference surface, which is not limited here.

[0083] Optionally, in combination with Figures 1 to 3 , the number of positioning members 230 can be 4, and every two positioning members 230 are arranged on one side of the fixed part 210 along the axial direction.

[0084] In some embodiments, each positioning member 230 abuts against the cable. Optionally, the positioning member 230 can also be designed with an elastic adjusting part. For example, the positioning member 230 can adopt a spring-loaded design to strengthen the fitting strength between the positioning member 230 and the cable.

[0085] It can be understood that when the positioning member 230 directly abuts against the cable, the two can provide a direct and physical constraint, thereby preventing the cable from deviating or distorting when passing through the positioning channel 300. This direct constraint helps to ensure that the axis of the cable is collinear with the axis of the positioning channel 300 and the wire inlet of the head, further enhancing the constraint and positioning ability of the cable deviation adjusting device to the cable and improving the precision and stability of the cable passing process.

[0086] In addition, by simultaneously abutting the cable with multiple positioning members 230, a more stable support structure can be formed, further reducing the possible shaking and deviation of the cable during the extrusion process. In addition, the design of the positioning member 230 abutting against the cable can ensure good contact between the positioning member 230 and the cable, thereby reducing wear caused by friction and helping to prolong the service life of the cable and the cable deviation adjusting device, and reducing quality problems caused by wear.

[0087] In some embodiments, in combination with Figures 1 to 3The fixed part 210 is formed as a fixed ring 210a, and the movable part 220 is formed as a movable ring 220a, which is rotatably arranged on the inner side or the outer side of the fixed ring 210a.

[0088] It can be understood that the fixed part 210 is formed as a fixed ring 210a, which provides a stable support structure for mounting and fixing the entire biasing device, and the movable part 220 is formed as a movable ring 220a, which can rotate relative to the fixed ring 210a, so as to adjust the position and shape of the positioning channel 300.

[0089] The movable ring 220a can be arranged on the inner side or the outer side of the fixed ring 210a, depending on the actual application requirements and layout. Optionally, in combination with Figures 1 to 3 The movable ring 220a is arranged on the inner side of the fixed ring 210a.

[0090] The projections of the plurality of fixed rings 210a in the reference plane are on the inner side or the outer side of the projection of the movable ring 220a in the reference plane. It can be seen that the positioning member 230 is arranged around the movable ring 220a, which helps to ensure that the positioning member 230 can be uniformly distributed around the movable ring 220a, thereby providing stable support and constraint.

[0091] The movable ring 220a is provided with a first connecting column 221, and the fixed ring 210a is provided with a second connecting column 211. The first connecting column 221 and the second connecting column 211 both extend along the axial direction of the positioning channel 300. The first connecting column 221 and the second connecting column 211 provide a pivot connection point for the positioning member 230, so that the positioning member 230 can rotate and adjust relative to the fixed ring 210a and the movable ring 220a.

[0092] The two ends of the positioning member 230 are pivotally connected with the first connecting column 221 and the second connecting column 211, respectively. This connection allows the positioning member 230 to be adjusted as necessary while maintaining a certain rigidity. By adjusting the angle between the positioning member 230 and the connecting column, the shape and position of the positioning channel 300 can be changed, thereby achieving adjustment of the position of the cable.

[0093] It can be seen that through the combination of the fixed ring 210a and the movable ring 220a and the pivot connection of the positioning member 230, accurate adjustment and stable positioning of the cable are achieved. This design improves the precision and stability of the cable passing through the entry port of the head, and also helps to reduce the problem of excessive eccentricity of the extruded layer caused by inaccurate positioning, thereby ensuring the quality and efficiency of cable production.

[0094] In some embodiments, in combination with Figures 2 to 4The positioning member 230 comprises a roller 231 and a linkage mechanism 232. The roller 231 is used to directly contact the cable to provide rolling support and reduce friction and wear, and the linkage mechanism 232 is responsible for connecting the roller 231 with the fixed ring 210a and the movable ring 220a to achieve position and angle adjustment of the roller 231.

[0095] The linkage mechanism 232 comprises a first linkage 2321 and a second linkage 2322. The first end of the first linkage 2321 is pivotally connected with the first connecting column 221, the first end of the second linkage 2322 is pivotally connected with the second connecting column 211, and the second end of the first linkage 2321 and the second end of the second linkage 2322 are pivotally connected. In this way, the design allows the roller 231 to be adjusted in angle while maintaining a certain position.

[0096] Optionally, the first linkage 2321 and the second linkage 2322 can be made of 45 steel to ensure sufficient strength and durability, and facilitate processing and connection.

[0097] The roller 231 is sleeved on the first linkage 2321 and can rotate relative to the first linkage 2321, so that the roller 231 can be adjusted in position under the driving of the linkage mechanism 232, and can also rotate relative to the linkage to adapt to the movement of the cable, reduce the friction between the roller 231 and the cable, and improve the stability and service life of the cable deviation adjusting device. Optionally, the material of the roller 231 can be rubber.

[0098] The rollers 231 of the plurality of positioning members 230 jointly define a positioning channel 300. The positioning channel 300 defined by the plurality of rollers 231 is used for the cable to pass through. By adjusting the angle of the linkage mechanism 232 and the position of the roller 231, the shape and size of the channel can be correspondingly controlled, so as to achieve accurate positioning and constraint of the cable.

[0099] It can be seen that the positioning member 230 in the cable deviation adjusting device combines the roller 231 and the linkage mechanism 232, realizes flexible adjustment and stable positioning of the cable, improves the accuracy and stability of the cable passing through the entry port of the machine head, and also helps to reduce the problem of excessive eccentricity of the extruded layer caused by inaccurate positioning, and improves the production quality of the cable.

[0100] Optionally, a wear-resistant layer can be designed on the outer wall of the roller 231 to prolong its service life.

[0101] In some embodiments, in combination with Figures 1 to 3 The second linkage 2322 can be designed as an arc shape, and the second linkages 2322 of the plurality of positioning members 230 are all arranged to open towards the clockwise direction or the counterclockwise direction.

[0102] It can be understood that the arc-shaped design of the second connecting rod 2322 makes it more suitable for the preset cable deviation adjustment requirement. When the movable part 220 drives the positioning member 230 to rotate, the arc-shaped design of the second connecting rod 2322 can improve the stability of the rotation of the positioning member 230. In addition, the arc-shaped design can more effectively utilize the space, for example, in a compact installation environment, which helps to reduce the volume and weight of the entire cable deviation adjustment device while maintaining the required deviation adjustment capability. In addition, the arc-shaped second connecting rod 2322 can also disperse its own stress, improve the strength and durability of the connecting rod mechanism 232.

[0103] In addition, the second connecting rod 2322 of all positioning members 230 is arranged to open towards the same direction (clockwise or counterclockwise), so that the movement of the plurality of positioning members 230 will be more coordinated and consistent, which helps to reduce the interference and friction that may exist during movement and improves the operation efficiency of the cable deviation adjustment device. This design also makes the installation and maintenance process simpler and more intuitive, so that the operating personnel can quickly identify and locate, and speed up the installation and maintenance speed.

[0104] In some embodiments, in combination Figures 1 to 3 , the plurality of positioning members 230 are located on at least one side of the fixed part 210 along the axial direction of the positioning channel 300. Optionally, the plurality of positioning members 230 can be divided into two groups, and the two groups of positioning members 230 are evenly arranged on both sides of the fixed part 210 along the axial direction of the positioning channel 300.

[0105] It can be understood that the plurality of positioning members 230 are evenly distributed around the positioning channel 300, and the plurality of positioning members 230 can be designed on either side of the axial direction of the positioning channel 300 or on both sides of the axial direction of the positioning channel 300. The specific design can depend on the actual cable deviation adjustment requirement and space limitation during design.

[0106] For example, if the cable needs to be adjusted before or after entering the positioning channel 300, the positioning member 230 can be arranged on the side of the fixed part 210 away from the head or close to the head. If adjustment is required before and after entering the positioning channel 300, the positioning member 230 can be arranged on both sides of the axial direction of the fixed part 210.

[0107] It can be seen that by arranging the plurality of positioning members 230 on at least one side of the fixed part 210 along the axial direction of the positioning channel 300, the design enhances the functionality and flexibility of the cable deviation adjustment device, optimizes the space layout, reduces the cost, and helps to achieve accurate adjustment and stable positioning of the cable.

[0108] In some embodiments, in combination Figures 1 to 3 , the movable part 220 is provided with an operating member 222, and the operating member 222 is used to drive the movable part 220 to rotate relative to the fixed part 210.

[0109] Optionally, the operating member 222 can be designed in various forms, such as a handle, a knob, a lever, etc., and can be designed according to the operating environment, use requirements, etc., which are not limited herein. For example, the operating member 222 can be a handle, one end of which is fixedly connected to the movable part 220, and the other end can be designed with a handrail for easy gripping.

[0110] Optionally, the connection between the operating member 222 and the movable part 220 can also be provided with a fine adjustment design to achieve stable and slow adjustment of the movable part 220 when the operating member 222 is rotated, so as to improve the adjustment accuracy. For example, the fine adjustment design can include connecting rods, gears, chains, etc., and the specific components can be selectively designed according to actual use requirements, as long as the stable and slow adjustment of the movable part 220 is achieved, which is not limited herein.

[0111] It can be understood that by designing the operating member 222, the user can conveniently control the rotation angle and speed of the movable part 220, thereby meeting the requirements for cable deviation adjustment. It can be seen that the addition of the operating member 222 on the movable part 220 improves the practicability of the cable deviation adjustment device, making the operation more convenient and the adjustment more accurate during actual operation, and thus achieving accurate adjustment of the shape and size of the positioning channel 300.

[0112] In some embodiments, in combination with Figures 1 to 3 The fixed part 210 is provided with an activity channel 212 that penetrates along the radial direction. The activity channel 212 connects the annular inner wall and the outer wall of the fixed part 210, and extends along the circumferential direction of the fixed part 210. In this way, an arc-shaped path is formed in the circumferential direction of the fixed part 210, and the operating member 222 is arranged in the activity channel 212 and slides in the activity channel 212.

[0113] The activity channel 212 provides a sliding path for the operating member 222, so that it can move along the circumferential direction of the fixed part 210. Through this movement, the operating member 222 can drive the movable part 220 to rotate, thereby realizing the rotation of the movable part 220 relative to the fixed part 210.

[0114] In this way, the user can adjust the position of the movable part 220 by simply sliding the operating member 222, without the need for using complex tools or equipment. In addition, the arc-shaped path of the activity channel 212 allows the user to intuitively see the position and movement direction of the operating member 222, thereby making it easier to operate and adjust.

[0115] It can be seen that the design of the activity channel 212 that penetrates along the radial direction of the fixed part 210 and allows the operating member 222 to slide in the channel improves the flexibility and operability of the cable deviation adjustment device, and also provides the user with a more intuitive and convenient operation experience, ensuring the convenience of the cable manufacturing, installation and maintenance process.

[0116] In some embodiments, in combination Figures 1 to 3 The cable biasing device further comprises a locking member 400, which is provided with a locked position and an unlocked position.

[0117] When in the locked position, the movable part 220 and the fixed part 210 are locked together, preventing the movable part 220 from rotating relative to the fixed part 210. When in the unlocked position, the locking member 400 is disengaged from the movable part 220 and / or the fixed part 210, and the movable part 220 is adapted to rotate relative to the fixed part 210.

[0118] Optionally, the locking member 400 can be implemented in the form of a buckle, a bolt, a spring, or the like.

[0119] Optionally, the locking member 400 can be manually operated, such as by rotating, pushing, or pressing to switch between the locked position and the unlocked position. Alternatively, the locking member 400 can be designed to be automatic or semi-automatic, and the switching between the locked position and the unlocked position can be achieved through sensors, motors, or other automatic control systems.

[0120] Optionally, the locking member 400 can be provided on the fixed part 210, and a plurality of positioning grooves can be uniformly formed on the outer wall of the movable part 220. The locking member 400 is opposite to the positioning grooves, and when the locking member 400 is rotated to the locked position, the locking member 400 is clamped in the positioning grooves.

[0121] Optionally, in combination Figures 1 to 3 Two locking members 400 can be designed, and each of the two locking members 400 is provided at the two ends of the fixed part 210 in the radial direction. The design of the two locking members 400 can enhance the locking degree of the locked position. Alternatively, a plurality of locking members 400, such as three or four, can be designed, and the specific number can be designed according to actual use requirements, which is not limited herein.

[0122] The design of the locking member 400 allows the user to lock the relative positions of the movable part 220 and the fixed part 210 when the positioning member 230 is rotated to the preset position, thereby preventing the cable from being displaced or damaged due to accidents or misoperations. In the locked state, the relative positions between the movable part 220 and the fixed part 210 are fixed, which helps to improve the stability of the entire cable biasing device. After being unlocked, the user can conveniently adjust the position of the movable part 220 to meet different cable biasing requirements.

[0123] It can be seen that the design of the locking member 400 provides the user with the ability to lock the relative positions of the movable part 220 and the fixed part 210 when needed, thereby improving the safety and stability of the cable biasing device. In addition, the design of the locking member 400 also provides flexibility in allowing the movable part 220 to rotate relative to the fixed part 210 when adjustment is needed.
