[0007] As a preferred solution of the present invention, the number of the wiring harness components can be adaptively installed according to the number of cables actually installed.

[0008] As a preferred solution of the present invention, the plurality of arc-shaped clamping recesses are distributed in an array with equal spacing on the left and right sides, and each column includes two arc-shaped clamping recesses symmetrically distributed about the center of the threading tube, and the left and right width of the arc-shaped clamping recess is 0.5 to 1.2 mm greater than the left and right width of the elastic clamp.

[0009] As a preferred solution of the present invention, a serpentine spring piece is fixedly installed between the front wall and the rear wall of the arc-shaped clamping recess, the left end of the serpentine spring piece is fitted with the left wall of the arc-shaped clamping recess, and the right end of the serpentine spring piece is fitted with the right wall of the arc-shaped clamping recess, and the curvature of the serpentine spring piece is adapted to the curvature of the arc-shaped clamping recess.

[0013] As a preferred solution of the present invention, the front wall and the rear wall of the cable duct can be fixedly installed with side frames by bolts, and the tops of the two side frames are fixedly installed with multiple truss beams distributed at equal intervals on the left and right by bolts.

[0014] As a preferred solution of the present invention, a slot cover is detachably mounted on the top of the cable trough by screws, a plurality of left and right distributed foot plates are fixedly mounted on the bottom of the cable trough, and suspension screw rods are fixedly mounted on the front and rear ends of the foot plates.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, a single-strand cable is inserted into a threading tube from one end thereof and gradually fed into the threading tube, so that the cable moves along the inner wall of the threading tube toward the other end until the cable comes out of the other end of the threading tube. In this way, each cable is sequentially passed through a plurality of threading tubes to achieve independent installation of the plurality of cables, thereby avoiding entanglement of the cables with each other and facilitating the replacement of damaged cables at a later time.

[0017] 2. In the present invention, the rotation of the threading tube drives multiple arc-shaped clamping recesses and multiple serpentine spring pieces to rotate. After the rotation, the two arc-shaped clamping recesses just overlap with the positions of the two front and rear elastic clamps. The rebound force of the front and rear clamping springs in a compressed state is released, pushing the front and rear sliders to move toward the middle along the slide groove. The movement of the two sliders drives the two elastic clamps to move toward the middle together through the two clamping plates. The two elastic clamps move toward the middle to clamp the front and rear serpentine spring pieces, so that the two serpentine spring pieces collapse toward the inside of the threading tube through the two arc-shaped clamping recesses, thereby providing front and rear clamping effects on the cables, achieving cable fixation, avoiding loosening of the cables inside the threading tube, and improving the stability of cable power supply.

[0018] 3. In the present invention, after the two serpentine springs are subjected to the clamping force of the two elastic clamps acting on the surface of the cable, the reverse force caused by the cable on the serpentine springs will be transmitted to the two elastic clamps, causing the two elastic clamps to undergo elastic deformation, and the buffer spring inside the inner collapse cavity is compressed and stores force, thereby achieving a secondary buffering effect, avoiding excessive clamping force of the elastic clamps on the serpentine springs, that is, avoiding the problem of the serpentine springs clamping and damaging the cable, thereby achieving the dual effects of convenient cable fixation and protective measures.

[0019] 4. In the present invention, the shielding effect of the serpentine spring sheet on the arc-shaped clamping recess is such that the cable will not pass out from the arc-shaped clamping recess during the threading process inside the threading tube, thereby ensuring that the cable can be accurately passed out from the other end of the threading tube to achieve cable threading.

[0020] 5. In the present invention, a threading tube corresponding to the damaged cable is rotated to rotate the two arc-shaped clamping recesses and displace them with the front and rear elastic clamps. During this period, the front and rear elastic clamps are acted upon by the outer wall of the threading tube to move away from each other, compressing the front and rear clamping springs. The two clamping springs move away from each other to release the clamping effect of the two serpentine springs. The two serpentine springs recover under the action of their own rebound force to release the clamping effect on the outer wall of the cable. At this time, the cable can be pulled out from the inside of the threading tube to replace the cable, making cable repair and replacement more convenient and more efficient.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 10 The technical solution provided by the present invention specifically includes the following embodiments:

[0034] In this embodiment: a combined cable tray with a fixed structure includes a cable trough 100 and a cable bundle component 200. The cable bundle component 200 is fixedly installed inside the cable trough 100. The number of cable bundle components 200 can be adaptively installed according to the number of cables actually installed.

[0035] The wiring harness component 200 includes a threading tube 201, which is rotatably installed inside the wire slot 100. The outer wall of the threading tube 201 is penetrated by a plurality of arc-shaped clamping recesses 202, and a serpentine spring 203 is fixedly installed between the front wall and the rear wall of the arc-shaped clamping recess 202. The wiring harness component 200 also includes a base 204 fixedly installed inside the wire slot 100, and a slide groove 205 is opened on the top of the base 204. Two sliders 206 symmetrically distributed front and back are slidably installed inside the slide groove 205. A clamping plate 208 is fixedly installed on the side where the two sliders 206 are close to each other. The two clamps The side surfaces close to the holding plate 208 are fixedly installed with elastic clamps 209, and the elastic clamps 209 are sequentially distributed at the front and rear of the threading tube 201. The side surfaces away from the two sliders 206 are fixedly installed with clamping springs 207, and the end of the clamping spring 207 away from the slider 206 is fixedly connected to the inner wall of one end of the slide groove 205. An inner collapse cavity 2010 is opened inside the elastic clamp 209, and a plurality of buffer springs 2011 distributed at equal intervals on the left and right are fixedly installed inside the inner collapse cavity 2010. The side surface of the elastic clamp 209 away from the clamping plate 208 is provided with an inwardly concave arc surface structure.

[0036] Specifically, a single-strand cable is passed through one end of the threading tube 201 and gradually fed into the threading tube 201, so that the cable moves along the inner wall of the threading tube 201 to the other end until the cable comes out of the other end of the threading tube 201. In this way, each cable is passed through the multiple threading tubes 201 in turn, so that multiple cables can be independently installed to avoid the cables from being entangled with each other. At the same time, it is also convenient to replace damaged cables in the later stage. After the cable passes through the threading tube 201, the multiple arc-shaped clamping recesses 202 and the multiple snake-shaped spring pieces 203 are driven to rotate 90 degrees by rotating the threading tube 201. After rotating 90 degrees, the two arc-shaped clamping recesses 202 just overlap with the positions of the two front and rear elastic clamps 209, and the rebound force of the two front and rear clamping springs 207 in a compressed state is released, pushing the front and rear sliders 206 to move toward the middle along the slide groove 205. The two sliders 206 move through the two clamping plates 208 to drive the two elastic clamps 209 to move together. The two elastic clamps 209 move toward the middle and clamp the front and rear serpentine spring pieces 203, so that the two serpentine spring pieces 203 collapse toward the inside of the threading tube 201 through the two arc-shaped clamping notches 202, thereby providing a front and rear clamping effect on the cable, achieving the fixation of the cable, preventing the cable from loosening inside the threading tube 201, and improving the stability of the cable power supply. It should be noted that after the two serpentine spring pieces 203 are subjected to the clamping force of the two elastic clamps 209 on the cable surface, the reverse force caused by the cable on the serpentine spring piece 203 will be transmitted to the two elastic clamps 209, causing the two elastic clamps 209 to undergo elastic deformation, and the buffer spring 2011 inside the inner collapse cavity 2010 is compressed and stored, thereby playing a secondary buffering effect, avoiding excessive clamping force of the elastic clamp 209 on the serpentine spring piece 203, that is, avoiding the problem of the serpentine spring piece 203 clamping and damaging the cable, achieving the dual effects of convenient cable fixation and protective measures, and having strong practicality.

[0037] It should be added that if one of the cables is damaged and needs to be replaced, first rotate the wire threading tube 201 corresponding to the damaged cable 90 degrees, so that the two arc-shaped clamping recesses 202 are rotated and misaligned with the front and rear elastic clamps 209. During this period, the front and rear elastic clamps 209 are moved away from each other by the outer wall of the wire threading tube 201, compressing the front and rear clamping springs 207. The two clamping springs 207 move away from each other to release the clamping effect of the two serpentine springs 203. The two serpentine springs 203 recover under the action of their own rebound force and release the clamping effect on the outer wall of the cable. At this time, the cable can be pulled out from the inside of the wire threading tube 201 to replace the cable, making cable repair and replacement more convenient and more efficient.

[0038] In this embodiment: the base 204 is fixedly connected to the wire trough 100 by screws, the left side and the right side of the base 204 are fixedly installed with the adapter 2014, the threading tube 201 movably penetrates the left side and the right side of the adapter 2014, and the outer wall of the threading tube 201 is rotatably connected to the inner wall of the through hole of the adapter 2014;

[0039] Specifically, by setting up a screw connection between the base 204 and the wire trough 100, the number of bases 204 can be adjusted according to the number of cables to ensure that no redundant bases 204 appear inside the wire trough 100, thereby avoiding waste of raw materials. At the same time, the screw installation is also convenient for disassembly, which is beneficial to the maintenance and replacement of the base 204. Through the fixed connection between the adapter hoop 2014 and the base 204, the wire threading tube 201 is rotatably installed on the top of the base 204 and is located between the front and rear elastic clamps 209, which further improves the rotation stability of the wire threading tube 201 and further ensures the stability of the cables inside the wire threading tube 201.

[0040] In this embodiment: a plurality of arc-shaped clamping recesses 202 are arranged in an array with equal spacing from left to right, and each row includes two arc-shaped clamping recesses 202 symmetrically distributed about the center of the threading tube 201, and the left and right width of the arc-shaped clamping recess 202 is greater than the left and right width of the elastic clamp 209 by 0.5 to 1.2 mm;

[0041] Specifically, since the left and right widths of the elastic clamp 209 are smaller than the left and right widths of the arc-shaped clamping recess 202, when the front and rear elastic clamps 209 move toward the middle, they can be clamped into the interior of the arc-shaped clamping recess 202, thereby clamping the serpentine spring 203 to collapse into the interior of the threading tube 201, forming a clamping effect on the cable. At the same time, the 0.5-1.2 mm gap set between the arc-shaped clamping recess 202 and the elastic clamp 209 can fully ensure that the elastic clamp 209 can be smoothly clamped into the interior of the arc-shaped clamping recess 202. At the same time, there will be no large gap between the left and right ends of the elastic clamp 209 and the left and right inner walls of the arc-shaped clamping recess 202, thereby ensuring that the elastic clamp 209 has sufficient clamping contact area for the serpentine spring 203, so that the serpentine spring 203 can better clamp the cable.

[0042] In this embodiment: the left end of the serpentine spring piece 203 is fitted with the left wall of the arc-shaped clamping recess 202, and the right end of the serpentine spring piece 203 is fitted with the right wall of the arc-shaped clamping recess 202, and the curvature of the serpentine spring piece 203 is adapted to the curvature of the arc-shaped clamping recess 202;

[0043] Specifically, a single-strand cable is passed through the threading tube 201 from one end thereof and gradually fed into the threading tube 201, so that the cable moves along the inner wall of the threading tube 201 to the other end. During this period, due to the shielding effect of the serpentine spring piece 203 on the arc-shaped clamping recess 202, the cable will not pass out from the arc-shaped clamping recess 202 during the threading process inside the threading tube 201, thereby ensuring that the cable passes out from the other end of the threading tube 201, thereby realizing the cable threading arrangement.

[0044] In this embodiment: a straightening rod 2013 is fixedly installed between the front wall and the rear wall of the slide groove 205, a clearance hole 2012 is opened through the lower front part of the slider 206, the inner wall of the clearance hole 2012 is slidably connected to the outer wall of the straightening rod 2013, and the clamping spring 207 is sleeved on the outer periphery of the straightening rod 2013;

[0045] Specifically, by providing the clearance hole 2012, direct interference between the slider 206 and the straightening rod 2013 is avoided, thereby ensuring the free movement of the slider 206 along the inner wall of the slide groove 205. By providing the straightening rod 2013, the clamping spring 207 is straightened, thereby avoiding the problem of the clamping spring 207 being bent after compression and causing the elasticity of the clamping spring 207 to decrease.

[0046] In this embodiment: a plurality of capillary heat dissipation holes 2001 are formed through the outer wall of the threading tube 201, and the plurality of capillary heat dissipation holes 2001 are distributed in an equiangular circular array, and the capillary heat dissipation holes 2001 are distributed at equal intervals on the left and right sides;

[0047] Specifically, by providing a plurality of buffer springs 2011, the heat dissipation effect of the cable can be provided, which helps to improve the stability and service life of the cable.

[0048] In this embodiment: two coupling blocks 2015 are fixedly installed on the left end of the threading tube 201, and the two coupling blocks 2015 are symmetrically distributed about the center of the threading tube 201, and two coupling grooves 2016 are opened on the right end of the threading tube 201, and the two coupling grooves 2016 are symmetrically distributed about the center of the threading tube 201, and the specifications and positions of the coupling grooves 2016 are adapted to the specifications and positions of the coupling blocks 2015;

[0049] Specifically, by inserting the coupling block 2015 at the left end of one of the threading tubes 201 into the coupling groove 2016 at the right end of an adjacent threading tube 201, the overall transmission effect of multiple threading tubes 201 can be achieved by rotating one of the threading tubes 201, thereby eliminating the need to twist the multiple threading tubes 201 connected in sequence one by one, thereby improving the convenience of use.

[0050] In this embodiment: the front wall and the rear wall of the cable duct 100 can be fixedly installed with side frames 500 by bolts, and the tops of the two side frames 500 are fixedly installed with multiple truss beams 600 with equal spacing on the left and right by bolts;

[0051] Specifically, the number of harness components 200 is determined according to the number of cables required in the installation area, and then the harness components 200 are fixedly installed inside the wire trough 100. Initially, the base 204 is fixedly installed on the top wall of the wire trough 100 by screws. Since the adapter 2014 and the base 204 are fixed, the threading tube 201 is also rotated and installed on the top of the base 204 through the adapter 2014, and the base 204 on each harness component 200 is fixed. If the wire trough 1 If the bottom wall of the cable trough 100 is fully installed with the front-to-back distributed wiring harness components 200, but the requirement for the number of cables cannot be met, the two side frames 500 can be fixed on the front and back inner walls of the cable trough 100 by screws, and a plurality of truss beams 600 can be installed on the top of the two side frames 500 at equal distances on the left and right by screws, and then the base 204 can be installed on the top of the truss beams 600, so that the wiring harness components 200 can be installed in layers inside the cable trough 100, and the cable accommodation capacity inside the cable trough 100 can be increased.

[0052] In this embodiment: a slot cover 101 is detachably mounted on the top of the wire slot 100 by screws, a plurality of foot plates 300 distributed left and right are fixedly mounted on the bottom of the wire slot 100, and a suspension screw rod 400 is fixedly mounted on the front and rear ends of the foot plates 300;

[0053] Specifically, by sealing the slot cover 101 on the top of the cable trough 100 to prevent external dust from entering the interior of the cable trough 100, it is beneficial to protect the cables and the wiring harness components 200 and increase the service life of the cables and the wiring harness components 200. By connecting the foot plate 300 and the suspension screw rod 400, the cable trough 100 is fixed on the top of the wall of the installation area, thereby fixing the cable trough 100 to prevent the cable trough 100 from falling off.

[0054] In the present invention, a combined cable tray with a fixed structure is used. First, the number of the harness components 200 is determined according to the number of cables required in the installation area. Then, the harness components 200 are fixedly installed inside the wire trough 100. Initially, the base 204 is fixedly installed on the top wall of the wire trough 100 by screws. Since the adapter 2014 and the base 204 are fixed, the threading tube 201 is also rotatably installed on the top of the base 204 through the adapter 2014, and the base 201 on each harness component 200 is fixedly installed on the top wall of the wire trough 100 by screws. 04 are all fixed. If the bottom wall of the cable trough 100 is fully installed with the front and rear distributed cable tying components 200, but still cannot meet the requirement of the number of cables, the two side frames 500 can be fixed on the front and rear inner walls of the cable trough 100 by screws, and multiple truss beams 600 are installed on the top of the two side frames 500 at equal distances by screws, and then the base 204 is installed on the top of the truss beam 600, so that the cable tying components 200 can be installed in layers inside the cable trough 100, which can increase the cable accommodating capacity inside the cable trough 100;

[0055] After all the wire harness components 200 are installed, the wire duct 100 is fixedly placed on the top of the wall of the installation area by connecting the foot plate 300 with the suspension screw rod 400, so as to fix the wire duct 100 and prevent the wire duct 100 from falling off. After the wire duct 100 is installed, the wires are threaded. At this time, the single-strand cable is inserted into the inside of the wire threading tube 201 from one end thereof, and gradually fed into the inside of the wire threading tube 201, so that the cable moves along the inner wall of the wire threading tube 201 to the other end. During this period, due to the shielding effect of the serpentine spring piece 203 on the arc-shaped clamping recess 202, the cable will not pass through the arc-shaped clamping recess 202 during the threading process inside the wire threading tube 201, until the cable passes through the other end of the wire threading tube 201. In this way, each cable is passed through the inside of multiple wire threading tubes 201 in turn, so as to realize the independent installation of multiple cables, avoid the cables from being entangled with each other, and also facilitate the replacement of damaged cables in the later stage.

[0056] After the cable passes through the inside of the threading tube 201, the plurality of arc-shaped clamping recesses 202 and the plurality of serpentine springs 203 are driven to rotate 90 degrees by rotating the threading tube 201, and the threading tube 201 is rotatably connected to the adapter hoop 2014, which can further ensure the rotation stability of the threading tube 201. After rotating 90 degrees, the two arc-shaped clamping recesses 202 just overlap with the positions of the two front and rear elastic clamps 209, and the rebound force of the two front and rear clamping springs 207 in a compressed state is released, pushing the front and rear sliders 206 to move toward the middle along the slide groove 205. The two sliders 206 move through the two clamping plates 208 to drive the two elastic clamps 209 to move toward the middle together, and the two elastic clamps 209 move toward the middle to clamp the two front and rear serpentine springs 203, so that the two serpentine springs 203 pass through the two arc-shaped clamping recesses 20 The two serpentine springs 203 are subjected to the clamping force of the two elastic clamps 209 on the surface of the cable, and the reverse force caused by the cable on the serpentine springs 203 will be transmitted to the two elastic clamps 209, causing the two elastic clamps 209 to undergo elastic deformation, and the buffer spring 2011 inside the inner collapse cavity 2010 is compressed and stored, thereby playing a secondary buffering effect, avoiding excessive clamping force of the elastic clamp 209 on the serpentine springs 203, that is, avoiding the problem of the serpentine springs 203 clamping and damaging the cable, achieving the dual effects of convenient cable fixation and protective measures, and having strong practicality;

[0057] If one of the cables is damaged and needs to be replaced during use, first rotate the threading tube 201 corresponding to the damaged cable 90 degrees to rotate the two arc-shaped clamping recesses 202 to be misaligned with the front and rear elastic clamps 209. During this period, the front and rear elastic clamps 209 are moved away from each other by the outer wall of the threading tube 201, compressing the front and rear clamping springs 207. The two clamping springs 207 move away from each other to release the clamping effect of the two serpentine springs 203. The two serpentine springs 203 recover under the action of their own rebound force and release the clamping effect on the outer wall of the cable. At this time, the cable can be pulled out from the inside of the threading tube 201 to replace the cable, making cable maintenance and replacement more convenient and more efficient.

[0058] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention.
