Description

Technical Field

[0001] The invention relates to the technical field of cable installation, and in particular to a high-flexibility elastic soft cable and an installation method thereof. Background Art

[0002] In the application scenarios of modern electrical equipment and various automation systems, cables, as an important component for power and signal transmission, have increasingly diverse and complex performance requirements. With the continuous improvement of industrial automation and the miniaturization and precision of equipment, higher requirements are placed on the flexibility and adjustability of cables.

[0003] Traditional cables are relatively fixed in structure and often face many limitations when they need to be bent or changed in shape to adapt to different installation environments or equipment layouts. For example, in some space-constrained equipment or in situations where cables need to be frequently moved and adjusted, the rigid cable structure cannot meet the needs of flexible wiring. In addition, in some special environments, cables may need to withstand certain external forces or frequent bending movements, and traditional cables are prone to damage, affecting their electrical performance and service life.

[0004] Based on this, some flexible cables have appeared on the market to solve the problem of limited existing cable structure scenarios. Although this type of flexible cable has good flexibility, it often lacks an effective angle adjustment mechanism to accurately control the bending angle and posture of the flexible cable. This lack of precise control may affect the stability of the flexible cable during installation, and it is easy to change its shape due to external forces or equipment vibrations during subsequent use, thereby affecting the normal operation of the equipment. In addition, in some locations in the flexible cable that require frequent bending, if there is no special clamping and fixing device, it is very likely that the structural strength of the cable bend cannot be ensured, causing local wear of the cable, affecting the overall performance and service life of the cable. Summary of the invention

[0005] In view of the problem that the shape and posture of flexible cables cannot be effectively fixed in the prior art, the present invention provides a highly flexible elastic cable and an installation method, so that the flexible cable can still maintain good stability and structural strength for a long time in certain positions where frequent bending is required, thereby improving the overall performance and service life of the cable.

[0007] In some embodiments, the outer locking ring is provided with a plurality of outer sliding grooves, and during the relative movement of the inner locking ring and the outer locking ring, the plurality of outer sliding grooves are respectively connected with the plurality of inner sliding grooves, so that the plurality of rollers can move between the plurality of inner sliding grooves and the plurality of outer sliding grooves.

[0008] In some embodiments, the inner slide groove is a trapezoidal groove, and the width of the opening of the trapezoidal groove on the side close to the axis of the cable body is smaller than the diameter of the roller; the outer slide groove is an inverted trapezoidal groove, and the width of the opening of the inverted trapezoidal groove on the side away from the axis of the cable body is smaller than the diameter of the roller.

[0010] In some embodiments, the arc-shaped groove further has a recessed section connected to the accommodating section, and the inner bottom wall of the outer locking ring is provided with a protrusion extending toward the arc-shaped groove, and the shape of the protrusion is adapted to the contour of the recessed section.

[0011] In some embodiments, the locking assembly includes a sleeve, an upper locking member, a lower locking member, a locking column and an elastic member; wherein, the sleeve and the lower locking member are respectively arranged at the corners of adjacent clamping plates, the locking column passes through the sleeve, the upper locking member and the lower locking member are respectively sleeved on the outside of the locking column, the elastic member is located between the sleeve and the upper locking member, and under the elastic force of the elastic member, the upper locking member can be locked and matched with the lower locking member.

[0012] In some embodiments, a button is disposed at the top end of the locking column, a limiting hole is provided at the bottom end of the locking column, and the locking assembly further includes a limiting pin that cooperates with the limiting hole.

[0013] In some embodiments, the limiting hole is a gourd-shaped hole or a bar-shaped hole.

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0023] Reference Figure 1-Figure 5 As shown, an embodiment of the present invention provides a high-flexibility elastic soft cable, comprising a cable body 100 and an adjusting device 200 arranged on the cable body 100, wherein the adjusting device 200 comprises a lock core 210 and a bending arm 220 connected to the lock core 210; wherein the lock core 210 comprises an inner lock ring 211 with a plurality of inner slide grooves 2111, an outer lock ring 212 sleeved on the outer side of the inner lock ring 211, and a plurality of rollers 213 respectively arranged in the plurality of inner slide grooves 2111, During the rotation of the outer locking ring 212 relative to the inner locking ring 211, the multiple rollers 213 can approach each other along the inner walls of the multiple inner slide grooves 2111 to clamp the outer wall of the cable body 100; the bending arm 220 has a plurality of clamping plates 221 wrapped around the outer wall of the cable body 100, and the multiple clamping plates 221 are hingedly connected by a locking assembly 222, and when the locking assembly 222 switches between the locked state and the unlocked state, the bending arm 220 can switch between different bending angles.

[0024] It should be noted that the high-flexibility elastomeric soft cable provided in this application refers to a cable made of thermoplastic elastomer (TPE), also known as artificial rubber or synthetic rubber. Its products have the excellent properties of high elasticity, aging resistance, and oil resistance of traditional cross-linked vulcanized rubber, and at the same time have the characteristics of convenient processing and wide processing methods of ordinary plastics. When TPE is used in cables, its performance at the operating temperature is similar to that of vulcanized rubber, and it can also be processed and reprocessed by increasing the temperature like thermoplastic plastics.

[0025] In addition, the cable body in the highly flexible elastic soft cable usually includes structures such as conductors, insulators, fillers and sheaths. Among them, the material of the conductor can be annealed copper wire, the single wire can be tinned or not, and the tinned copper wire can be covered with an effective tin layer; the number of conductor cores, the nominal cross-sectional area of ​​the conductor, the maximum diameter of the single wire in the conductor, and the maximum value of the conductor resistance at 20°C can have a variety of different specifications (refer to Table 1 below for details), and the present application does not limit the specific values ​​of each parameter in the conductor; the material of the insulator can be a thermoplastic elastomer, preferably one of nitrile-polyvinyl chloride elastomer insulation (PVC / NBR), styrene-based thermoplastic elastomer insulation (TPS) or thermoplastic vulcanized rubber insulation (TPV), and the average thickness of the insulator is not less than the specified value listed in Table 1, but the thickness of a certain point of the insulator can be less than the specified value, as long as the thickness of the point is not less than the specified value 90% is sufficient; the filler can be made of non-hygroscopic material, or the sheath can be embedded between the cores to form a filler, and there should be no harmful interaction between the components of the filler and the insulation and / or the sheath; the sheath can also be made of a thermoplastic elastomer, preferably one of nitrile-polyvinyl chloride elastomer insulation (PVC / NBR), styrene-based thermoplastic elastomer insulation (TPS) or thermoplastic polyurethane elastomer sheath (TPD), and the average thickness of the sheath is not less than the specified value listed in Table 1 below, but the thickness of a certain point of the sheath may be less than the specified value, as long as the thickness of the point is not less than 85% of the specified value; in addition, the average outer diameter of the cable body can refer to the range specified in Table 1, and the ovality of the cable body should not exceed 15% of the upper limit of the specified average outer diameter.

[0026] Table 1:

[0027]

[0028] In a specific example, the specific structure of the cable body 100 can refer to Figure 6As shown, the cable body 100 includes a conductor 110, an insulator 120, a filler 130, an inner lining layer 140 and a sheath 150 arranged in sequence from the inside to the outside; preferably, the number of cores of the conductor 110 can be three, and the three-core conductor 110 is distributed in a herringbone shape, and the filler 130 is located in the gap between the inner lining layer 140 and the insulator 120. Among them, the conductor 110 can be a tinned copper wire, the insulator 120 and the sheath 150 can be made of thermoplastic elastomer, the material of the filler 130 can be polypropylene fiber, glass fiber, polyurethane foam, etc., the material of the inner lining layer 140 can be polyvinyl chloride, polyethylene, steel strip, steel wire, aluminum strip, etc., and the present application does not limit the specific materials of the above-mentioned layers. Furthermore, in order to better improve the tensile strength of the highly flexible elastomeric soft cable, the cable body 100 may also include a tensile member (not shown in the figure) arranged in the gap between the filler 130 and the insulator 120, wherein the tensile member may be a galvanized tensile soft steel wire rope, Kevlar tensile fiber, etc. The present application does not limit the specific structure of the tensile member.

[0029] It should also be noted that the cable body 100 is different in different application scenarios, due to the differences in its actual length, the type of electrical equipment connected, the wiring path, etc., so the cable body 100 itself may have multiple positions that need to be bent during the wiring process. Therefore, the present application can configure the adjustment device 200 as multiple, and respectively set the multiple adjustment devices 200 at multiple positions that need to be bent in the cable body 100, so that the cable body 100 presents a more stable shape as a whole. Exemplarily, there can be three adjustment devices 200, and the present application does not limit the specific number thereof.

[0030] The inner lock ring 211 and the outer lock ring 212 in the lock core 210 are nested and cooperated with each other. On the one hand, the user can drive the inner lock ring 211 and the outer lock ring 212 to rotate relative to each other by twisting the outer lock ring 212 clockwise or counterclockwise with one hand and holding the inner lock ring 211 with the other hand; on the other hand, the user can also drive the inner lock ring 211 and the outer lock ring 212 to rotate relative to each other by twisting the inner lock ring 211 clockwise or counterclockwise with one hand and holding the outer lock ring 212 with the other hand. The present application does not limit the user's operation method of the lock core 210.

[0031] It should be noted that since both the inner locking ring 211 and the outer locking ring 212 are sleeved on the outer side of the cable body 100, the inner locking ring 211 is usually provided with an inner locking hole 2112 for accommodating the cable body 100, and the outer locking ring 212 is provided with an outer locking hole 2121 that matches the profile of the inner locking ring 211. The inner locking hole 2112 and the outer locking hole 2121 can both be circular holes, or the inner locking hole 2112 and the outer locking hole 2121 can both be polygonal holes (such as triangular holes, square holes, hexagonal holes, etc.); and the shapes of the inner locking hole 2112 and the outer locking hole 2121 can be the same or different, and the present application does not limit the specific shapes of the inner locking hole 2112 and the outer locking hole 2121. In addition, the outer contours of the inner locking ring 211 and the outer locking ring 212 can both be circular, or square, hexagonal, etc., and the present application does not limit the outer contours of the inner locking ring 211 and the outer locking ring 212.

[0032] Optionally, refer to Figure 3 and Figure 4 As shown, the edges of both sides of the inner locking ring 211 have inner flanges 2113 extending radially outward, and the edges of both sides of the outer locking ring 212 have outer flanges 2122 extending radially outward, and the outer flanges 2122 on both sides are located between the inner flanges 2113 on both sides. The inner flange 2113 may be a polygonal flange, and the outer flange 2122 may be a circular flange. The present application does not limit the specific shapes of the inner flange 2113 and the outer flange 2122.

[0033] The setting of the inner flange 2113 and the outer flange 2122 can limit the position of the outer locking ring 212 during the relative rotation of the inner locking ring 211 and the outer locking ring 212, thereby avoiding the shaking of the outer locking ring 212 relative to the inner locking ring 211 along the axial direction of the cable body 100 to the greatest extent, thereby facilitating the improvement of the structural stability of the lock core 210.

[0034] Preferably, the multiple inner grooves 2111 in the inner lock ring 211 are evenly distributed along the circumference of the inner lock ring 211, and correspondingly, the multiple rollers 213 located in the inner grooves 2111 are also evenly distributed along the circumference of the inner lock ring 211. Exemplarily, the number of the inner grooves 2111 and the number of rollers 213 can both be eight. This arrangement can make the clamping force of the multiple rollers 213 acting on the outer wall of the cable body 100 more evenly distributed when the multiple rollers 213 clamp the outer wall of the cable body 100, thereby facilitating the improvement of the clamping stability and clamping effect of the lock core 210 on the cable body 100.

[0035] It is understandable that when the roller 213 moves in the inner groove 2111, on the one hand, the inner groove 2111 and the roller 213 can be reasonably configured to achieve sliding cooperation between the inner groove 2111 and the roller 213; on the other hand, the relative movement between the inner groove 2111 and the roller 213 can be reasonably configured to achieve the relative movement between the inner groove 2111 and the roller 213. In one embodiment, a sliding shaft is provided at both ends of the roller 213, and a sliding groove is provided on both side walls of the inner groove 2111. Through the cooperation between the sliding groove and the sliding shaft, the sliding cooperation between the roller 213 and the inner groove 2111 can be achieved; in another embodiment, the axial dimension of the roller 213 is configured to be slightly smaller than the width of the inner groove 2111, so that a gap is formed between the roller 213 and the inner groove 2111, and the gap can ensure that the roller 213 moves in the inner groove 2111, and can also prevent the roller 213 from falling out of the inner groove 2111 due to the excessive gap.

[0036] In addition, the multiple clamping plates 221 in the bending arm 220 are used to clamp the outer wall of the coated cable body 100, which can be a U-shaped clamping plate, a circular clamping cylinder, a semicircular clamping plate, etc., and the present application does not limit the specific structure of the clamping plate 221. In addition, the number of the clamping plates 221 can be two, three, four, five, etc., and the present application does not limit the specific number of the clamping plates 221.

[0037] In order to make the clamping area or clamping angle formed between the multiple clamping plates 221 adapt to the bending angle and shape of the cable body 100, the multiple clamping plates 221 are connected by hinges, so that the bending arm 220 can adapt to different bending angles and different shapes of the cable body 100. Further, in order to keep the multiple clamping plates 221 at a certain determined angle, the present application locks the positions of the multiple clamping plates 221 by setting a locking assembly 222, and the locking assembly 222 is set at the hinge position of the multiple clamping plates 221.

[0038] Regarding the specific structure of the locking assembly 222, the present application can have a variety of different implementation methods. For example, the structure of the locking assembly 222 can be a gear locking structure, a magnetic locking structure, or a threaded locking structure, etc., and the present application has no limitation on this.

[0039] The high-flexibility elastic soft cable provided by the present invention can be bent and adjusted as needed during use through the design of the adjustment device 200, so that it can adapt to different installation environments and equipment layouts, thereby improving the flexibility and operability of the cable. First, the adjustment device 200 includes a lock core 210 and a bending arm 220. The setting of the lock core 210 can effectively clamp the outer wall of the cable body 100 to prevent the cable body 100 from loosening or sliding relative to the adjustment device 200 during use, which is conducive to ensuring the stability of the cable body 100 and the reliability of the electrical connection with other electrical equipment; and, through the relative rotation between the inner lock ring 211 and the outer lock ring 212 in the lock core 210, the clamping of the outer wall of the cable body 100 by multiple rollers 213 is realized, and the operation method is simple and has a stable clamping effect. Secondly, the setting of multiple clamping plates 221 in the bending arm 220 expands the angle adjustment range of the cable body 100 to a certain extent, so that the cable can be applied to various complex scenes. In addition, the cable body 100 can also be processed using high-quality flexible materials to further improve the cable's bending resistance and service life, and greatly reduce wear at locations where the cable is frequently bent.

[0040] In some embodiments, continue to refer to Figure 3 and Figure 4 As shown, the outer locking ring 212 is provided with a plurality of outer sliding grooves 2124, and during the relative movement of the inner locking ring 211 and the outer locking ring 212, the plurality of outer sliding grooves 2124 are respectively connected with the plurality of inner sliding grooves 2111, so that the plurality of rollers 213 can move between the plurality of inner sliding grooves 2111 and the plurality of outer sliding grooves 2124.

[0041] During the movement of the outer locking ring 212 relative to the inner locking ring 211, on the one hand, the outer slide groove 2124 is misaligned with the inner slide groove 2111, and the bottom wall of the outer locking ring 212 can squeeze the outer wall of the roller 213, thereby driving the roller 213 to move along the inner wall of the inner slide groove 2111 toward the axis of the cable body 100, that is, the multiple rollers 213 approach each other to achieve clamping of the outer wall of the cable body 100; on the other hand, the inner slide groove 2111 is connected to the outer slide groove 2124, and the roller 213 can move in the inner slide groove 2111 and the outer slide groove 2124. The reaction force of the outer wall of the cable body 100 on the roller 213 drives the roller 213 away from the axis of the cable body 100, that is, the multiple rollers 213 move away from each other to achieve unlocking of the outer wall of the cable body 100.

[0042] It should be noted that the number of outer grooves 2124 can be the same as or different from the number of inner grooves 2111, and this is not limited in the present application. When the number of outer grooves 2124 and inner grooves 2111 is the same, the rotation process of the outer lock ring 212 relative to the inner lock ring 211 causes the lock core 210 to have two gears, namely the locking gear and the unlocking gear (see the above content for details); when the number of outer grooves 2124 and inner grooves 2111 is different, the rotation process of the outer lock ring 212 relative to the inner lock ring 211 causes the lock core 210 to have three gears, namely the locking gear, the unlocking gear and the semi-locking gear; when the lock core 210 is in the semi-locking gear, a part of the multiple inner grooves 2111 are connected to the outer grooves 2124, and the remaining inner grooves 2111 are connected to the outer grooves 2124. 1 is in a closed state under the blocking of the inner wall of the outer locking ring 212; at this time, a part of the multiple rollers 213 enters the inner slide groove 2111 and / or the outer slide groove 2124 under the reaction of the outer wall of the cable body 100, and the other part of the rollers 213 still clamps the outer wall of the cable body 100 under the squeezing of the inner wall of the outer locking ring 212, but because only a part of the rollers 213 clamp the cable body 100, the clamping force of the semi-locking gear is smaller than that of the locking gear, and the clamping stability is worse, and the user can adjust the position of the lock core 210 on the cable body 100 without worrying about the problem of over-adjustment.

[0043] Further, refer to Figure 7 and Figure 8 As shown, the inner groove 2111 can be a trapezoidal groove, and the width of the opening of the trapezoidal groove on the side close to the axis of the cable body 100 is smaller than the diameter of the roller 213; the outer groove 2124 can be an inverted trapezoidal groove, and the width of the opening of the inverted trapezoidal groove on the side away from the axis of the cable body 100 is smaller than the diameter of the roller 213.

[0044] The structure of the trapezoidal groove and the inverted trapezoidal groove can effectively limit the roller 213 during the clamping process of the roller 213 or when it moves to the outer slide groove 2124, preventing the roller 213 from escaping from the inner slide groove 2111 or the outer slide groove 2124, further improving the stability and reliability of the lock core 210.

[0045] In some embodiments, reference Figure 9-11 As shown, in addition to the trapezoidal groove, the inner slide groove 2111 can also be an arc groove, and the arc groove has a receiving section 2114 and a guide section 2115 connected to each other, and the minimum inner diameter of the receiving section 2114 is not less than the diameter of the roller 213, and the minimum inner diameter of the guide section 2115 is not greater than the diameter of the roller 213.

[0046] The arc-shaped inner slide groove 2111 makes the roller 213 move more smoothly in the inner slide groove 2111. The accommodation section 2114 is used to accommodate the roller 213 when the lock core 210 is in the unlocking position, and the guide section 2115 is used to make the roller 213 clamp the outer wall of the cable body 100 when the lock core 210 is in the locking position. In addition, by limiting the size of the accommodation section 2114 and the guide section 2115, not only can the inner lock ring 211 have sufficient accommodation space to accommodate the roller 213, but also the roller 213 can be prevented from falling out of the inner slide groove 2111 when the lock core 210 is in the locking position.

[0047] It should be noted that when the inner slide groove 2111 is an arc-shaped groove, the arc-shaped groove is formed by an arc-shaped top wall, an arc-shaped bottom wall and the side wall of the inner locking ring 211, and the top and bottom ends of the arc-shaped groove both have through openings; wherein, the arc-shaped top wall is a continuous regular arc, and the arc-shaped bottom wall is a continuous irregular arc, and the irregular arc is formed by connecting two arc segments with different radii and arc lengths, and the direction of one arc segment with a longer arc length is opposite to the direction of the other arc segment with a shorter arc length, the longer arc segment and the arc-shaped top wall are combined to form a accommodating section 2114, and the shorter arc segment and the arc-shaped top wall are combined to form a guiding section 2115. In addition, the connection between the longer arc segment and the shorter arc segment is not transitionally processed so that the connection has a convex structure. Therefore, when the roller 213 moves along the arc bottom wall and passes through the connection between the longer arc segment and the shorter arc segment, the user can clearly feel the frustration and can even hear a slight "click" prompt sound, which is beneficial for the user to confirm the gear status of the lock cylinder 210, thereby facilitating the user's experience.

[0048] Further, continue to refer to Fig.11 As shown, the arc groove also has a recessed section 2116 connected to the accommodating section 2114, and the inner bottom wall of the outer lock ring 212 is provided with a protrusion 2123 extending toward the arc groove, and the shape of the protrusion 2123 is adapted to the contour of the recessed section 2116. By providing the protrusion 2123 in the outer lock ring 212, when the outer lock ring 212 rotates, the roller 213 can be driven, thereby facilitating the switching of the lock core 210 between the unlocking gear and the locking gear.

[0049] Preferably, the protrusion 2123 may be an arc-shaped protrusion; accordingly, the profile of the recessed section 2116 is also arc-shaped. The provision of the recessed section 2116 can ensure that the outer lock ring 212 is kept in a stable relative position relative to the inner lock ring 211 to a certain extent when the lock core 210 is in the unlocking gear position by confining the protrusion 2123 in the recessed section 2116, thereby avoiding unnecessary relative rotation between the outer lock ring 212 and the inner lock ring 211, thereby facilitating the improvement of the stability and reliability of the lock core 210 structure.

[0050] It should also be noted that the bottom wall of the recessed section 2116 is connected to the arc-shaped bottom wall of the accommodating section 2114, and the arc length and radius of the bottom wall of the recessed section 2116 are different from those of the arc-shaped bottom wall of the accommodating section 2114. Based on this, a convex structure can also be formed at the connection position between the bottom wall of the recessed section 2116 and the arc-shaped bottom wall of the accommodating section 2114, and when the roller 213 moves between the accommodating section 2114 and the recessed section 2116, the user can also clearly feel the sense of frustration, or can hear a slight "click" prompt sound.

[0051] In some embodiments, reference Fig.12 and Fig.13 As shown, the locking assembly 222 includes a sleeve 2221, an upper locking piece 2222, a lower locking piece 2223, a locking column 2224 and an elastic piece 2225; wherein the sleeve 2221 and the lower locking piece 2223 are respectively arranged at the corners of adjacent clamping plates 221, the locking column 2224 passes through the sleeve 2221, the upper locking piece 2222 and the lower locking piece 2223 are respectively sleeved on the outside of the locking column 2224, the elastic piece 2225 is located between the sleeve 2221 and the upper locking piece 2222, and under the elastic force of the elastic piece 2225, the upper locking piece 2222 can be locked and matched with the lower locking piece 2223.

[0052] It can be understood that since there are multiple clamping plates 221 in the bending arm 220, especially when the multiple clamping plates 221 are U-shaped clamping plates, the connection positions of the clamping plates 221 are actually in the form of an up-and-down staggered connection, that is, the sizes of two adjacent clamping plates 221 will be slightly different, so as to avoid to a certain extent the problem of inconvenience in hinge connection when the clamping plates 221 are the same size.

[0053] Exemplarily, when there are three clamping plates 221, and all of the clamping plates 221 are U-shaped clamping plates, they are named as the first clamping plate, the second clamping plate, and the third clamping plate, respectively; wherein one end of the first clamping plate is connected to the inner locking ring 211, and the other end is hinged to the first end of the second clamping plate, and the second end of the second clamping plate is hinged to the end of the third clamping plate. Furthermore, when the bending arm 220 is in a horizontal state, the upper side wall of the first clamping plate and the upper side wall of the third clamping plate can be located above the upper side wall of the second clamping plate, that is, the distance between the two side walls of the first clamping plate and the third clamping plate is greater than the distance between the two side walls of the second clamping plate. At this time, the sleeve 2221 in the locking assembly 222 can be set in the two side walls of the first clamping plate and the third clamping plate, and the lower locking piece 2223 can be set in the two side walls of the second clamping plate; or, the sleeve 2221 can be set in the two side walls of the second clamping plate, and the lower locking piece 2223 can be set in the two side walls of the first clamping plate and the third clamping plate.

[0054] It should also be noted that the locking and matching method between the upper locking member 2222 and the lower locking member 2223 in the locking assembly 222 can be gear matching, magnetic matching, snap-fit ​​matching, etc. When the matching method is gear matching, the upper locking member 2222 and the lower locking member 2223 can be face gears; when the matching method is magnetic matching, the upper locking member 2222 and the lower locking member 2223 can be magnets; when the matching method is snap-fit ​​matching, one of the upper locking member 2222 and the lower locking member 2223 can be a buckle, and the other can be a slot. The present application does not limit the specific structure of the upper locking member 2222 and the lower locking member 2223.

[0055] In addition, since the upper locking member 2222 can be locked and matched with the lower locking member 2223 under the elastic force of the elastic member 2225, it can be understood that when the lower locking member 2223 is fixed in the side wall of the clamping plate 221, the locking column 2224 should be able to pass through the lower locking member 2223 and slide up and down relative to it, and the upper locking member 2222 should be able to move with the movement of the locking column 2224, and the two ends of the elastic member 2225 can respectively abut against the sleeve 2221 and the upper locking member 2222; and the elastic member 2225 can be a compression spring, a leaf spring, a spring plate, etc., and the present application does not limit the specific structure of the elastic member 2225.

[0056] Further, refer to Fig.13 As shown, a button 2226 is provided at the top of the locking column 2224, a limiting hole 2227 is provided at the bottom of the locking column 2224, and the locking assembly 222 also includes a limiting pin 2228 that matches the limiting hole 2227. The setting of the button 2226 facilitates the user to operate the locking assembly 222, and is conducive to the switching of the unlocking process and the locking process of the locking assembly 222; the cooperation between the limiting hole 2227 and the limiting pin 2228 can prevent the locking column 2224 from escaping from the clamping plate 221, which is conducive to the stable performance of the locking effect of the locking assembly 222, thereby improving the locking effect and stability of the locking assembly 222, and preventing looseness or misoperation during use.

[0057] Optionally, the limiting hole 2227 is a gourd hole or a bar hole. When the limiting hole 2227 is a gourd hole and the locking assembly 222 is in the locked state, the limiting pin 2228 cooperates with the lower hole in the gourd hole; when the locking assembly 222 is in the unlocked state, the limiting pin 2228 cooperates with the upper hole in the gourd hole; the design of this gourd hole structure can improve the locking effect of the locking assembly 222 to a certain extent. When the gourd hole is a bar hole, it is conducive to improving the smoothness of the switching of the locking assembly 222 between the unlocked state and the locked state.

[0058] In some embodiments, reference Figure 4As shown, the surface of the outer locking ring 212 is provided with anti-slip stripes (not marked in the figure). The setting of the anti-slip stripes can increase the friction of the surface of the outer locking ring 212, making it easier for the operator to apply better force when screwing the outer locking ring 212. At the same time, it can also prevent the outer locking ring 212 from accidentally rotating due to hand slippage during use, thereby improving the safety and operability of the adjustment device 200.

[0059] In addition, an embodiment of the present invention further provides a method for installing a high-flexibility elastic body soft cable, which is applied to the above high-flexibility elastic body soft cable and includes the following steps: S100, moving the adjusting device to the position of the cable body to be bent.

[0061] S300, switching the locking assembly to an unlocked state, and adjusting the bending angles of the multiple clamping plates in the bending arm.

[0062] S400, after the bending angle is determined, the locking assembly is switched from an unlocked state to a locked state to fix the position of the cable body.

[0063] The installation method of the high-flexibility elastic soft cable provided by the present invention can realize rapid and accurate installation and adjustment of the cable, improve the installation efficiency and quality of the cable, and ensure the stability and reliability of the cable during use.
