Description

Technical Field

[0001] This utility model belongs to the technical field of threaders, and in particular relates to a threader box and a threader. Background Technology

[0002] Cable pullers were initially used primarily for pulling cables through walls, but later their application expanded to include pulling fiber optic cables in sewers and other similar systems. Cable pullers offer advantages such as saving time and effort, and improving work efficiency. They can be used for cleaning telecommunications ducts and laying fiber optic cables, electrical cables, and plastic conduits.

[0003] Fish-shaped cable threaders are a type of cable threader favored by users due to their small size and portability. Users need to manually pull the handle to control the cable release. However, existing fish-shaped cable threaders lack a braking function, making the cable release speed uncontrollable, especially in areas requiring slow threading around corners. This lack of slow release can easily damage the cable being threaded by the fish-shaped threader. Utility Model Content

[0004] In view of this, it is necessary to provide a threader box and a threader for solving the above-mentioned technical problems.

[0005] A cable puller box, the cable puller box comprising:

[0006] The housing includes a first housing cover and a second housing cover, the first housing cover being mounted on the second housing cover, and a receiving cavity being formed between the first housing cover and the second housing cover, the receiving cavity being used to receive the threading rope;

[0007] A connecting frame is disposed on the periphery of the accommodating cavity and is rotatably connected to the first shell cover and the second shell cover respectively, for limiting the connecting frame between the first shell cover and the second shell cover;

[0008] A lifting handle is disposed on the outside of the housing and connected to the connecting frame, and a finger cavity is formed between the lifting handle and the connecting frame. A threading channel is formed on the lifting handle and communicates with the receiving cavity to allow the threading rope to pass through.

[0009] A brake handle is rotatably mounted on the lifting handle, and the brake handle portion extends into the finger cavity to control the locking / unlocking of the portion of the threading rope located within the threading channel.

[0010] Understandably, the design of the brake handle allows users to control the locking / unlocking of the threading rope passing through the threading channel while simultaneously pulling the cable puller box by lifting the handle. This enables control over the speed at which the threading rope is released, making the cable puller with this box suitable for various threading applications and preventing damage to the cables being threaded. The user-friendly operation further enhances the overall user experience.

[0011] In one embodiment, the brake handle has a locking surface, and the brake handle can be stopped by abutting against a portion of the threaded rope located within the threading channel via the locking surface;

[0012] The locking surface is arc-shaped.

[0013] Understandably, the brake lever uses an arc-shaped locking surface to abut and limit the contact between itself and the threaded rope to achieve locking control of the threaded rope. This can buffer the locking of the threaded rope by the brake lever and prevent the threaded rope from being damaged due to concentrated pressure.

[0014] In one embodiment, a stop block is provided on the brake handle, and the stop block is disposed inside the lifting handle;

[0015] The stop block can abut against the lifting handle to limit the rotational travel of the brake handle on the lifting handle when the cable is released from locking.

[0016] It is understandable that the stop block and the lifting handle are used to limit the rotation of the brake handle when unlocking the threaded rope, so that the maximum angle at which the brake handle can be held by hand is limited when the brake handle is unlocked. This makes it easier for the user to hold the brake handle and lock the threaded rope.

[0017] In one embodiment, a limiting protrusion is formed on the brake handle, and the limiting protrusion is disposed at one end of the brake handle that extends into the finger cavity;

[0018] The limiting protrusion is angled upwards toward the connecting frame.

[0019] Understandably, the structure of the limiting protrusion prevents the brake lever from slipping when the user holds it, thus making it easier for the user to operate the brake lever.

[0020] In one embodiment, the connecting frame is provided with a threading hole, and the threading channel communicates with the receiving cavity through the threading hole;

[0021] The threading hole is located in the extending direction of the threading channel.

[0022] In one embodiment, a first circular groove is formed on the first shell cover, which can be inserted and engaged with the connecting frame.

[0023] Furthermore, a second circular groove is formed on the second shell cover, and the second circular groove is inserted into the connecting frame.

[0024] In one embodiment, the connecting frame includes a circular ring body and an extending rib, the extending rib being disposed on the outer peripheral wall of the circular ring body and connected to the lifting handle;

[0025] The ring body is respectively inserted into the first circular groove and the second circular groove; and the extended rib is disposed between the first shell cover and the second shell cover.

[0026] In one embodiment, the connecting frame is integrated with the lifting handle.

[0027] In one embodiment, a first connecting platform is formed on the first cover, and a second connecting platform is formed on the second cover. The second connecting platform is matched with the first connecting platform and connected to the first connecting platform.

[0028] The outer peripheral wall of the first connecting platform is connected to the outer peripheral wall of the second connecting platform and forms the inner wall of the accommodating cavity.

[0029] In addition, this application also claims protection for a threader, including the threader box described above.

[0030] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0031] The cable threader box and cable threader claimed in this application utilize a brake handle structure, allowing the user to control the locking / unlocking of the threading rope passing through the threading channel while simultaneously pulling the cable threader box by holding the brake handle. This enables control over the speed at which the threading rope is released, making the cable threader with this box suitable for various threading applications and preventing damage to the cables threaded by the cable threader. Furthermore, the user-friendly operation enhances the overall user experience of using the cable threader. Attached Figure Description

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] like Figures 1 to 3 As shown, the threader box 100 provided in this application includes a housing 10, a connecting frame 20, and a lifting handle 30. The housing 10 includes a first cover 11 and a second cover 12. The first cover 11 is mounted on the second cover 12, and the first cover 11 and the second cover 12 form a receiving cavity 101 for receiving threaded ropes (not shown). The connecting frame 20 is disposed around the receiving cavity 101 and is rotatably connected to the first cover 11 and the second cover 12, respectively, for limiting the connecting frame 20 to the first cover 101. Between the cover 11 and the second cover 12; a lifting handle 30 is disposed on the outside of the housing 10 and connected to the connecting frame 20, and a finger cavity 102 is formed between the lifting handle 30 and the connecting frame 20. A threading channel 31 is formed on the lifting handle 30, which communicates with the receiving cavity 101 for threading the rope to pass through; wherein, a brake handle 40 is rotatably mounted on the lifting handle 30, and part of the brake handle 40 extends into the finger cavity 102 for controlling the locking / unlocking of the portion of the rope located in the threading channel 31. Here, the connecting frame 20 and the lifting handle 30 are connected as a whole, which can be integrally injection molded from plastic material. It should be noted that the aforementioned finger cavity 102 specifically refers to the cavity that can accommodate a person's fingers when holding the lifting handle 30.

[0043] As can be seen from the above, the cable threader box 100 of this application, through the structural design of the brake handle 40, allows the user to control the locking / unlocking of the threading rope passing through the threading channel 31 by holding the brake handle 40 while pulling the cable threader box 100 by pulling the handle 30. This enables control over the speed at which the threading rope is released, making the cable threader using the cable threader box 100 suitable for different threading application scenarios and preventing damage to the cables threaded by the cable threader. In this process, the user operation is simple, which can further improve the user experience of using the cable threader.

[0044] like Figures 2 to 4As shown, in one embodiment, a first connecting platform 111 is formed on the first cover 11, and a second connecting platform 121 is formed on the second cover 12. The second connecting platform 121 is matched with the first connecting platform 111 and connected to the first connecting platform 111. Specifically, screws, bolts and other connectors are used to realize the connection between the first connecting platform 111 and the second connecting platform 121, thereby realizing the assembly connection between the first cover 11 and the second cover 12.

[0045] In this embodiment, the outer peripheral wall of the first connecting platform 111 is connected to the outer peripheral wall of the second connecting platform 121 and forms the inner cavity wall of the receiving cavity 101. That is, the threading rope housed in the receiving cavity 101 can be wound around the outer peripheral walls of the first connecting platform 111 and the second connecting platform 121. Here, the inner peripheral walls of the first connecting platform 111 and the second connecting platform 121 respectively enclose and form interconnected square channels 13. This reduces the overall weight of the housing 10, making it easier for the user to lift the threader box 100; it also makes the overall structural design of the housing 10 more ergonomic and improves its aesthetic appeal.

[0046] like Figure 3 , Figure 4 As shown, in one embodiment, a first circular groove 112 is formed on the first cover 11, which can be inserted into the connecting frame 20; and a second circular groove 122 is formed on the second cover 12, which can be inserted into the connecting frame 20. This allows for the assembly connection between the connecting frame 20 and the first cover 11 and the second cover 12, and precise positioning of the assembly position between the first cover 11 and the second cover 12. Utilizing the structural features of the first circular groove 112 and the second circular groove 122, the connecting frame 20 can rotate relative to the first cover 11 and the second cover 12. This allows the threader using the threader box 100 to release the threaded rope sequentially through the threading channel 31 within the receiving cavity 101 by rotating the housing 10 on the connecting frame 20 during the threading process.

[0047] like Figure 3 As shown, in this embodiment, the connecting frame 20 includes a circular body 21 and an extending rib 22. The extending rib 22 is disposed on the outer peripheral wall of the circular body 21 and is connected to the lifting handle 30. The circular body 21 is respectively inserted into the first circular groove 112 and the second circular groove 122. The extending rib 22 is disposed between the first shell cover 11 and the second shell cover 12.

[0048] like Figure 2 , Figure 3As shown, in one embodiment, a threading hole 211 is provided on the connecting frame 20, and the threading channel 31 is connected to the receiving cavity 101 through the threading hole 211; wherein, the threading hole 211 is arranged in the extending direction of the threading channel 31. This allows the threaded rope located in the receiving cavity 101 to pass through the threading hole 211 and directly exit from the threading channel 31. During this process, the threading channel 31 can guide the release of the threaded rope. Here, the threading hole 211 is provided on the annular body 21.

[0049] like Figure 5 As shown, in one embodiment, the brake handle 40 has a locking surface 41, which is arc-shaped, and the brake handle 40 can be limited by the locking surface 41 pressing against the portion of the threaded rope located in the threading channel 31. This utilizes the frictional resistance generated when the locking surface 41 of the brake handle 40 presses against the threaded rope to provide resistance to the unloading of the threaded rope, thus achieving locking control of the threaded rope. During this process, the arc-shaped surface structure provides a buffering effect on the locking of the threaded rope by the locking surface 41, preventing damage to the threaded rope due to concentrated pressure.

[0050] like Figure 5 As shown, in one embodiment, a stop block 42 is provided on the brake handle 40, and the stop block 42 is disposed inside the lifting handle 30; and the stop block 42 can abut against the lifting handle 30 to limit the rotational stroke of the brake handle 40 on the lifting handle 30 when the cable is released, so that the maximum angle at which the brake handle 40 can be held by hand when the brake handle 40 is unlocked is limited, which makes it convenient for the user to hold the brake handle 40 to limit the locking of the cable.

[0051] like Figure 5 As shown, in one embodiment, a limiting protrusion 43 is formed on the brake handle 40. The limiting protrusion 43 is disposed at one end of the brake handle 40 that extends into the finger cavity 102; wherein, the limiting protrusion 43 is tilted upwards toward the connecting frame 20. This allows the limiting protrusion 43 to limit the hand holding the brake handle 40 when the user holds it, preventing slippage, thus facilitating the user's operation of the brake handle 40.

[0052] In addition, this application also claims protection for a threader, including the threader box 100 described above.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
