Currently, the laying of optical fiber cables in cities is generally carried out underground, so many optical fiber cable pipes for laying underground optical fiber cables are generated.

[0003] However, with the high density and complexity of the optical fiber communication network, traditional single-channel or simply partitioned optical fiber threading pipes have deficiencies in aspects such as anti-interference, wiring efficiency, and flexibility of later maintenance. Especially in data centers, intelligent buildings, and industrial scenarios, it is necessary to accommodate multiple optical fibers simultaneously and avoid cross-interference, and there is an urgent need for a new type of multi-channel optical fiber threading pipe.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment:

[0027] Such as Figures 1-4As shown in the figure, an embodiment of the present invention provides a multi-channel optical fiber threading pipe, which includes an outer pipe 2, a first inner pipe 7, and a second inner pipe 11. A rotating shaft 10 is rotatably connected to the top end inside the outer pipe 2. The front and rear ends of the rotating shaft 10 are rotatably connected to the second inner pipe 11. The middle section of the rotating shaft 10 is fixedly sleeved with the first inner pipe 7. Semi-circular holes 17 and second circular holes 16 are respectively formed in the upper and lower sides of the front end faces of the first inner pipe 7 and the second inner pipe 11. A second square hole 14 is formed in the other side of the lower end of the front end faces of the first inner pipe 7 and the second inner pipe 11. Partition mechanisms 12 are installed inside the first inner pipe 7 and the second inner pipe 11 at the positions of the semi-circular holes 17 and the second circular holes 16.

[0028] Specifically, the first inner pipe 7 and the second inner pipe 11 are located inside the outer pipe 2. When the two are combined together, they form a triangular structure, and multiple holes are formed at the front end to form a multi-channel threading pipe for threading and installing multiple optical fiber cables. And each channel is independently separated, so as to avoid mutual interference between multiple optical fiber cables.

[0029] Refer to Figure 2 、 Figure 3 and Figure 6 As shown in, the partition mechanism 12 includes an elastic arc plate 1201. A support plate 1206 is fixedly arranged at the midpoint of one side of the outer wall of the elastic arc plate 1201. Convex blocks 1202 are fixedly arranged on both the front and rear end faces of the support plate 1206, and a placement groove 1205 is formed on one side of the convex block 1202. Clamping blocks 1203 are embedded in both placement grooves 1205. Connecting springs 1204 are fixedly arranged on both sides of one end of the two clamping blocks 1203 located inside the placement groove 1205. Two movable grooves 13 are formed on both sides of the semi-circular hole 17 on the first inner pipe 7 and the second inner pipe 11. Two movable grooves 13 are formed on both sides of the outer walls of the two second circular holes 16 on the first inner pipe 7 and the second inner pipe 11. The clamping blocks 1203 are embedded in the movable grooves 13.

[0030] Specifically, during use, by squeezing the clamping blocks 1203 located in the movable grooves 13 at the outer edge to make them contract inward, the clamping blocks 1203 are forced to squeeze the connecting springs 1204 at the rear end to contract. Then, by pulling the elastic arc plate 1201, the support plate 1206 on one side is driven to move horizontally. The support plate 1206 will drive the clamping blocks 1203 to move to the position of the movable groove 13 on the inner side and be embedded in the movable groove 13 at this position to complete the re-limiting and fixing effect; the convex blocks 1202 at the front and rear ends of the displaced support plate 1206 play an auxiliary limiting effect to avoid the phenomenon that the entire support plate 1206 detaches.

[0031] Refer to Figure 1 、 Figure 4 、 Figure 7 and Figure 8, a connecting sleeve 8 is fixedly arranged at the outer side edge of the rear end face of the outer tube 2. Limiting mechanisms 9 are installed at the midpoints of both sides of the outer wall of the connecting sleeve 8. The limiting mechanism 9 includes an outer rod 901. An inner rod 902 is fixedly arranged at the lower end face of the outer rod 901. An inner hole 903 is formed at the lower end of one side of the outer wall of the inner rod 902, and a contraction spring 904 is fixedly connected inside the inner hole 903. A plug 905 is fixedly arranged at one end of the contraction spring 904. Limiting holes 6 are formed at the front ends of both sides of the outer wall of the outer tube 2, and a jack 5 is formed on one side of the inner wall of the limiting hole 6, wherein the jack 5 penetrates through the front end face of the outer tube 2. The inner rod 902 is embedded in the limiting hole 6, and the plug 905 on one side of the inner rod 902 penetrates through the jack 5. The elastic arc plate 1201 is made of rubber material, and when the outer walls of the two elastic arc plates 1201 are attached to the inner wall of the second round hole 17, the second round hole 17 is a single channel;

[0032] Specifically, the outer rod 901 is threadedly sleeved on the connecting sleeve 8. When two outer tubes 2 need to be spliced and combined, the two outer tubes 2 are connected end to end, that is, the front end of one outer tube 2 is inserted into the connecting sleeve 8 at the rear end of the other outer tube 2. At this time, by twisting the outer rod 901, the lower inner rod 902 and the plug 905 outside the inner rod 902 are driven to rotate and move downward. Since the plug 905 adopts an upper and lower inclined surface structure, it contracts and is received inside the inner rod 902 when stressed. Subsequently, during the continuous downward push of the outer rod 901, it reaches the bottom end of the limiting hole 6, thereby achieving the limiting and fixing effect after splicing the two outer tubes 2; at the same time, since a jack 5 is arranged on one side of the inner wall of the limiting hole 6, when the plug 905 is located on one side of the jack 5, the contraction spring 904 at the rear end resets and pushes the plug 905 into the jack 5 to complete the auxiliary fixing effect.

[0033] Refer to Figure 1 , Figure 2 and Figure 4 , a fastener 1 is threadedly penetrated through the upper end face of the outer tube 2, and the lower end of the fastener 1 penetrates through the upper end of the second inner tube 11 and the upper end of the rotating shaft 10;

[0034] Specifically, the fastener 1 arranged at the upper end is used to limit the lower rotating shaft 10 and the second inner tube 11, and the first inner tube 7 is fixed on the rotating shaft 10, that is, when the first inner tube 7 and the second inner tube 11 are combined, the fastener 1 fixes them so that they will not separate.

[0035] Refer to Figure 2 , three first round holes 3 and one first square hole 4 are formed on both the front end face and the rear end face of the outer tube 2. When the first inner tube 7 and the second inner tube 11 are combined, the two semi-circular holes 17 are combined into a complete round hole, and multiple first round holes 3 correspond to the complete round hole and the two second round holes 16 before and after respectively. When the first inner tube 7 and the second inner tube 11 are combined, the two second square holes 14 are combined into a rectangular hole, and the two first square holes 4 correspond to the rectangular hole before and after respectively;

[0036] Specifically, the holes arranged at the front and rear of the entire threading tube are connected, which ensures the smoothness of the fiber optic cable threading and installation.

[0037] Reference Figure 1 , Figure 2 , Figure 4 , a side plate 15 is fixedly arranged on one side of the two second square holes 14, and the interior of the rectangular hole formed by the two second square holes 14 is divided into three channels by the two side plates 15;

[0038] Specifically, two inclined side panels 15 disposed on the inner side are used to separate the combined rectangular channels, so that three independent channels can be quickly formed, and the independent threading, installation and use of three optical fiber cables can be completed.

[0039] Embodiment 2:

[0040] Reference Figure 5 When the outer walls of the two elastic arc plates 1201 are separated from the No. 2 circular hole 17, the interior of the No. 2 circular hole 17 is divided into five independent channels.

[0041] Specifically, by utilizing the built-in dividing mechanism 12, when the dividing mechanism 12 is unfolded, based on the cooperation of the elastic arc plate 1201 and the support plate 1206, the entire circular hole is divided into five channels, thereby realizing a rapid increase in the channels.

[0042] Working principle: When the threading tube is used, multiple outer tubes 2 are connected end to end in sequence to realize the combined installation of the entire threading tube. When multiple outer tubes 2 are connected end to end in sequence, the front end of the outer tube 2 located at the rear end is inserted into the connecting sleeve 8 located at the rear end of the outer tube 2 located at the front end, and then the limiting mechanism 9 on the outside of the connecting sleeve 8 is twisted to make it embedded in the limiting hole 6, and the rotation is stopped when the plug block 905 is inserted into the plug hole 5; at this time, the end to end splicing combination between the two outer tubes 2 is completed;

[0043] Secondly, under normal conditions, the first inner tube 7 and the second inner tube 11 arranged inside the outer tube 2 are spliced and combined to form a triangular shape, with three circular holes and a square hole formed at the front and rear ends. The inside of the square hole is divided into three channels. At this time, the installation and threading of six optical fiber cables can be completed by using the three circular holes and the square hole. When additional threading channels are needed, the fastener 1 at the upper end can be twisted so that it no longer restricts the lower rotating shaft 10 and the second inner tube 11. Subsequently, the first inner tube 7 and the second inner tube 11 are flipped outwards. By pressing the block 1203, it squeezes the connecting spring 1204 at the rear end and then contracts inwards, and pulls the elastic arc plate 1201 located inside the circular hole to drive the support plate 1206 to move horizontally, prompting the block 1203 to be embedded into another movable slot 13 and then stop. At this time, the support plate 1206 and the elastic arc plate 1201 on both sides of the inner wall of the circular hole divide the entire circular hole into five threading channels, thereby achieving the effect of quickly adding threading channels.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
