Description

[0049] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0050] This utility model embodiment provides an optical cable threading mechanism, see [link to relevant documentation] Figure 1 As shown, the optical cable threading mechanism includes:

[0051] The unidirectional cable routing rod 100 is composed of multiple cable routing sections 1 connected end to end. Each cable routing section 1 is conical in shape, and the diameter M of the head of the cable routing section 1 and the diameter N of the tail of the cable routing section 1 satisfy the following condition: M < N.

[0052] The optical cable holder 200 has a first end 201 and a second end 202 located at both ends. The first end 201 is detachably connected to the cable section 1 located at the tail of the unidirectional cable rod 100, and the second end 202 is detachably connected to the optical cable 400.

[0053] When fiber optic cable threading is required, the user can clamp the unidirectional cable guide 100 and then operate it to pass through the slots of the fiber optic cable hooks that were installed at intervals during the existing fiber optic cable laying process. The unidirectional cable guide 100 drives the fiber optic cable holder 200 through the slots one by one, thereby driving the fiber optic cable to be laid, which is detachably connected to the second end 202, through the slots. Thus, the fiber optic cable to be laid can be laid parallel to the existing fiber optic cable, following its routing, without the need to install new fiber optic cable hooks or remove existing fiber optic cable hooks, greatly simplifying the fiber optic cable threading operation and improving threading efficiency.

[0054] Furthermore, the unidirectional cable routing rod 100 is composed of multiple cable routing sections 1 connected end to end, and each cable routing section 1 is conical in shape. Moreover, the diameter M of the head of the cable routing section 1 and the diameter N of the tail of the cable routing section 1 satisfy the condition: M < N. A "barb" structure is formed in the circumference of the unidirectional cable routing rod 100 to prevent the unidirectional cable routing rod 100 from slipping out of the slot in the reverse direction (opposite to the direction of passing through the slot) during the process of passing through the slot one by one. This helps to reduce the user's operating burden and improve the success rate and efficiency of optical cable threading.

[0055] In this embodiment of the utility model, the optical cable threading mechanism includes: a unidirectional cable guide 100, which is composed of multiple cable sections 1 connected end to end. Each cable section 1 is conical in shape, and the diameter M of the head of the cable section 1 and the diameter N of the tail of the cable section 1 satisfy the condition: M < N; an optical cable holder 200, which has a first end 201 and a second end 202 located at both ends. The first end 201 is detachably connected to the cable section 1 located at the tail of the unidirectional cable guide 100, and the second end 202 is detachably connected to the optical cable 400. By applying the optical cable threading mechanism of this embodiment of the utility model, the optical cable to be laid can be threaded through the slot of the optical cable hook of the existing optical cable without the need to set up a new optical cable hook or disassemble the optical cable hook of the existing optical cable, which greatly simplifies the operation of optical cable threading and improves the threading efficiency.

[0056] In some embodiments, see Figure 1 As shown, the optical cable threading mechanism also includes:

[0057] The anti-blocking head 300 is detachably connected to the cable section 1 located at the head end of the unidirectional cable routing rod 100.

[0058] In practical applications, the anti-blocking head 300 is the first component to contact the slot during the process of the user operating the unidirectional cable guide 100 to pass through the slot one by one. The anti-blocking head 300 can prevent the unidirectional cable guide 100 from being blocked by the slot. For example, the anti-blocking head 300 can push foreign objects out of the slot, so that the slot is unobstructed and the unidirectional cable guide 100 can pass through the slot smoothly, thereby improving the success rate and efficiency of optical cable threading.

[0059] In some embodiments, see Figure 1 and Figure 2 As shown, the anti-blocking head 300 includes:

[0060] The diameter L of the first end of the cone section 301 and the diameter K of the tail end of the cone section 301 satisfy the condition: L < K. The tail end of the cone section 301 is detachably connected to the cable section 1 located at the head of the unidirectional cable rod 100.

[0061] The spherical part 302 is provided at the head end of the conical part 301.

[0062] In this embodiment of the invention, the conical portion 301 forms a "barb" structure around the anti-blocking head 300 to prevent slippage from the slot in the opposite direction (opposite to the passing direction) during the process of passing through the slot. This helps reduce the user's operational burden and improves the success rate and efficiency of optical cable threading. A spherical portion 302 is provided at the head of the conical portion 301. On the one hand, this avoids the head of the optical cable threading mechanism from forming a sharp structure, thus preventing damage to the slot during threading. On the other hand, under user operation, the spherical portion 302 can also push foreign objects out of the slot, effectively preventing the unidirectional cable guide 100 from being blocked by the slot, allowing the unidirectional cable guide 100 to pass smoothly through the slot, thereby improving the success rate and efficiency of optical cable threading.

[0063] In some embodiments, see Figure 1 and Figure 3 As shown, the optical cable threading mechanism also includes:

[0064] Multiple connecting rods 2, each connecting rod 2 having a first connecting thread at both ends (not shown in the figure);

[0065] Each cable section 1 has a second connecting thread 11 at its head and tail, and the second connecting thread 11 can be connected with the first connecting thread (not shown in the figure).

[0066] By setting a connecting rod 2 between any two adjacent cable sections 1 with a threaded fit, multiple cable sections 1 are connected end to end to form a unidirectional cable rod 100.

[0067] In this embodiment of the utility model, through the above structure, a connecting rod 2 is provided between any two adjacent cable routing sections 1 in a threaded fit, and multiple cable routing sections 1 are connected end to end to form a unidirectional cable routing rod 100, which improves the firmness of the connection between multiple cable routing sections 1 in the unidirectional cable routing rod 100 and improves the reliability of the optical cable threading mechanism.

[0068] In some embodiments, see Figure 4 As shown, the first end 201 also has a second connecting thread 11;

[0069] A connecting rod 2 is provided between the first end 201 and the cable section 1 located at the tail of the unidirectional cable rod 100 through a threaded engagement, and the first end 201 and the cable section 1 located at the tail of the unidirectional cable rod 100 are detachably connected.

[0070] In this embodiment of the present invention, the first end 201 also has a second connecting thread 11; by providing a connecting rod 2 in threaded engagement between the first end 201 and the cable section 1 located at the tail of the unidirectional cable routing rod 100, the first end 201 and the cable section 1 located at the tail of the unidirectional cable routing rod 100 are detachably connected, thereby improving the firmness of the detachable connection between the first end 201 and the cable section 1 located at the tail of the unidirectional cable routing rod 100 and improving the reliability of the optical cable threading mechanism.

[0071] In some embodiments, see Figure 4 As shown, the optical cable retainer 200 is conical in shape. The diameter A of the first end of the optical cable retainer 200 and the diameter B of the last end of the optical cable retainer 200 satisfy the condition: A > B. The first end 201 is located at the first end of the optical cable retainer 200, and the second end 202 is located at the last end of the optical cable retainer 200. This arrangement helps to prevent the slots from damaging the optical cable during the cable threading process.

[0072] In some embodiments, the second end 202 has a clamping structure for clamping the optical cable. The second end 202 is detachably connected to the optical cable through the clamping structure, which simplifies the connection structure and makes it easier for users to remove the optical cable from the optical cable threading mechanism, thereby improving the optical cable threading efficiency.

[0073] In some embodiments, the optical cable fastener 200 includes: a first component, and a second component that can be spliced ​​with the first component;

[0074] The clamping structure includes: a first clamping groove formed in the first component, and a second clamping groove formed in the second component;

[0075] When the first component and the second component are spliced ​​together, the optical cable can be clamped in the clamping groove formed by the combination of the first clamping groove and the second clamping groove.

[0076] In some embodiments, the first component and the second component can be two parts obtained by cutting the optical cable fixer 200 along its axial cross-section. Understandably, the cross-sections of the two components (i.e., the axial cross-section of the optical cable fixer 200) have clamping grooves (i.e., a first clamping groove and a second clamping groove) that face each other after splicing. When the first component and the second component are spliced, the optical cable can be clamped in the clamping groove formed by the combination of the first and second clamping grooves. This configuration is simple in structure, helps reduce manufacturing costs, and also reduces the failure rate and improves reliability.

[0077] In some embodiments, the first clamping groove is lined with anti-slip rubber; and / or the second clamping groove is lined with anti-slip rubber, which can effectively prevent the optical cable from slipping when it is clamped, improve the success rate of threading, and improve the threading efficiency.

[0078] This utility model embodiment also provides an optical cable threading device, including: an operating rod with pliers, and an optical cable threading mechanism according to any one of the embodiments of this utility model.

[0079] In some embodiments, see Figure 5 As shown, one end of the operating lever 21 is provided with pliers 3, and the operating end of the pliers 3 is connected to one end of the pull line 4. The other end of the pull line 4 is located at the other end of the operating lever 21. The user can operate the pull line 4 to operate the pliers 3. Specifically, when the user pulls the pull line 4, the jaws of the pliers 3 close.

[0080] In some embodiments, see Figure 5 As shown, in the pliers 3, a spring 31 is also provided between the two hinged pliers. The spring 31 is used to provide the elastic force required for the pliers 3 to release the clamping force. That is, when the user does not pull the pull line 4, the release elastic force of the spring 31 causes the jaws of the pliers 3 to open.

[0081] In some embodiments, the pliers 3 are alligator pliers, which improves the gripping strength.

[0082] In some embodiments, see Figure 5 As shown, the operating lever 21 also has a handle 5, which the user uses to pull the pull line 4. Numerous handle structures exist in the prior art, and those skilled in the art are familiar with the aforementioned structure and how to pull the pull line 4 using the handle 5. Furthermore, the structure of the handle 5 is not a key improvement of this invention; therefore, the structure of the handle 5 is not further limited here. It should be noted that the lack of further limitation should not be interpreted as a lack of understanding.

[0083] In this embodiment of the utility model, see Figure 6 As shown, the arrows indicate the direction of cable threading. Users can use the operating lever to clamp the optical cable threading mechanism to perform optical cable threading operations.

[0084] It should also be noted that optical cables are often installed at high altitudes; in some embodiments, see [reference needed]. Figure 5 and Figure 6 As shown, an extension rod 6 can also be connected to the end of the operating lever 21 without the clamps 3 (i.e., the end for the user to hold and operate), which improves the convenience of operation and the efficiency of optical cable threading. In some embodiments, the operating lever 21 can be a telescopic rod, which can be extended by the user in actual application.

[0085] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of the present invention.
