Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of thread threaders, and in particular relates to a handheld thread 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] Handheld threaders are a type of threader that are popular among users due to their small size and portability. When using a handheld threader, the user needs to manually operate a dial on the device to control the thread feeding and unfeeding. However, because of the small overall size of the handheld threader, the area on the dial that the user can operate is also smaller, making it inconvenient to operate and thus affecting the user experience. Utility Model Content
[0004] In view of this, it is necessary to provide a handheld threader for solving the above-mentioned technical problems.
[0005] A handheld thread puller, comprising:
[0006] The housing includes a first housing cover and a second housing cover, wherein the first housing cover is mounted on the second housing cover, and the first housing cover and the second housing cover together form an accommodating cavity;
[0007] The bracket assembly includes a fixed bracket and a rotating bracket, wherein the fixed bracket abuts and limits the first housing cover, the rotating bracket abuts and limits the second housing cover, and the rotating bracket is rotatably connected to the fixed bracket;
[0008] The threading cord is at least partially contained within the receiving cavity in a coiled manner, with one end of the threading cord connected and limited to the rotating bracket, and the other end of the threading cord extending outward from the receiving cavity;
[0009] A handle, foldably connected to the rotating bracket, is detachable from the rotating bracket and extends out of the second cover to drive the rotating bracket to rotate relative to the fixed bracket, thereby retracting or extending the threading cord.
[0010] Understandably, the folding handle on the rotating bracket allows the user to operate the handheld threader by applying force to the handle that extends from the rotating bracket and out of the second cover. This provides the user with more operating space, making it easier to reel in and unload the threader and improving the user experience.
[0011] In one embodiment, a rib is provided on the end face of the rotating bracket away from the fixed bracket;
[0012] The handle is rotatably connected to the protruding rib via a pivot.
[0013] It is understandable that the handle is mounted on the rotating bracket using a pivot, which allows for a foldable connection of the handle on the rotating bracket and facilitates the mounting of the handle onto the rotating bracket.
[0014] In one embodiment, an extension protrusion is vertically connected to the handle, and a socket is formed on the rotating bracket, the socket being matched with the extension protrusion;
[0015] When the handle is folded onto the rotating bracket, the extended protrusion can be inserted into the socket.
[0016] Understandably, the vertically connected extension protrusion on the handle facilitates the gripping and application of force on the unfolded handle, thereby further facilitating the operation of the handheld cable threader for threading and unthreading. In addition, the rotating bracket uses a socket to accommodate the extension protrusion on the handle, ensuring that the extension protrusion does not affect the folding or unfolding of the handle on the rotating bracket.
[0017] In one embodiment, when the handle is unfolded from the rotating bracket, the extended protrusion is disposed on the outside of the second housing.
[0018] Understandably, the aforementioned positioning of the extended protrusions provides a sufficiently large space for the hand to grasp the extended protrusions on the unfolded handle, thus further facilitating the hand's operation of the handheld threader for threading and unthreading.
[0019] In one embodiment, a receiving cavity is formed between the protruding rib and the rotating bracket;
[0020] When the handle is folded onto the rotating bracket, the handle is housed within the receiving cavity.
[0021] In one embodiment, a spring clip is connected to the fixing bracket, and the handheld threader can be clamped and fixed by the spring clip.
[0022] It is understandable that using a clip to hold and secure the handheld threader allows the user to attach it to their waistband and carry it with them, thus facilitating its use.
[0023] In one embodiment, the clip is positioned perpendicular to the handle.
[0024] In one embodiment, the first cover and the second cover are provided with a hanging hole, and the handheld threader can be suspended and fixed through the hanging hole;
[0025] The suspension hole is located on the outside of the accommodating cavity and is independently disposed relative to the accommodating cavity.
[0026] It is understandable that using hanging holes to suspend and fix the handheld threader makes it easier to place the handheld threader when it is not in use.
[0027] In one embodiment, the fixed bracket includes a hook, and the rotating bracket includes a hook platform. The hook can be connected to the hook platform in a snap-fit manner to limit the rotating bracket to the fixed bracket and to limit the first cover to abut against the second cover.
[0028] It is understandable that the assembly limit between the fixed bracket and the rotating bracket is achieved by using the snap-fit between the hook and the hook platform. This facilitates the assembly connection between the fixed bracket and the rotating bracket, thereby facilitating the overall assembly of the handheld threader.
[0029] In one embodiment, the number of hooks is configured to be two, and the two hooks are symmetrically arranged with respect to the center line of the fixed bracket;
[0030] The fixed bracket is connected to a fixed plate, which is partially disposed between the two hooks to open the two hooks; and the side of the fixed plate facing the hook platform abuts and limits the two hooks.
[0031] It is understandable that the structure of the fixed plate can limit the assembly of the hook on the hook platform, thereby improving the stability of the assembly between the fixed bracket and the rotating bracket.
[0032] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:
[0033] The handheld threader claimed in this application utilizes a handle folded and connected to a rotating bracket, allowing the user to operate the threader by applying force to the handle, which extends from the rotating bracket and extends outwards from the second housing cover. This provides a larger operating space for the user's hand, facilitating the operation of the threader for threading and rewinding, and improving the user's operating experience.

Detailed Implementation
[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] 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.
[0047] like Figures 1 to 5As shown, the handheld threader 100 provided in this application includes a housing 10, a support assembly 20, a threading rope 30, and a handle 40. 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 together form an accommodating cavity 101. The support assembly 20 includes a fixed support 21 and a rotating support 22. The fixed support 21 abuts and limits the first cover 11, and the rotating support 22 abuts and limits the second cover 12. Furthermore, the rotating bracket 22 is rotatably connected to the fixed bracket 21; the threading rope 30 is at least partially coiled and housed within the receiving cavity 101, with one end of the threading rope 30 connected and limited by the rotating bracket 22, and the other end extending outward from the receiving cavity 101; the handle 40 is foldably connected to the rotating bracket 22, and the handle 40 can be unfolded from the rotating bracket 22 and extend out of the second cover 12 to drive the rotating bracket 22 to rotate relative to the fixed bracket 21, thereby retracting and extending the threading rope 30. It should be noted that the threading rope 30 is made of a material with a certain degree of hardness, specifically manganese steel, so that while the rotating bracket 22 rotates on the fixed bracket 21, the retracting and extending of the threading rope 30 can be controlled.
[0048] As can be seen from the above, the handheld threader 100 of this application can utilize the handle 40 folded and connected to the rotating bracket 22, so that when the user uses the handheld threader 100, the handle 40, which unfolds from the rotating bracket 22 and extends out of the second cover 12, can be applied to the handle 40, which provides a larger operating space for the hand, thereby facilitating the user's operation of the handheld threader 100 for threading and unthreading, and improving the user's operating experience.
[0049] like Figures 1 to 3 As shown, in one embodiment, the first cover 11 and the second cover 12 are perforated by a hanging hole 110. The hanging hole 110 is located on the outside of the receiving cavity 101 and is independently disposed relative to the receiving cavity 101. That is, the placement of the hanging hole 110 on the housing 10 does not affect the receiving cavity 101 of the housing 10. Furthermore, the handheld cable threader 100 can be suspended and fixed through the hanging hole 110. In other words, when the handheld cable threader 100 is not in use, the user can suspend and fix it through the hanging hole 110, that is, the handheld cable threader 100 can be hung on the wall.
[0050] like Figure 4 , Figure 6 and Figure 7As shown, in one embodiment, the fixed bracket 21 includes a hook 211, and the rotating bracket 22 includes a hook platform 221. The hook 211 can be connected to the hook platform 221 in a snap-fit manner to limit the rotating bracket 22 onto the fixed bracket 21 and to limit the first cover 11 and the second cover 12 to abut against each other. That is, the fixed bracket 21 and the rotating bracket 22 can be assembled and limited by the snap-fit between the hook 211 and the hook platform 221, which facilitates the assembly and connection between the fixed bracket 21 and the rotating bracket 22, thereby facilitating the overall assembly of the handheld threader 100. Here, the hook platform 221 is annular, so that when the rotating bracket 22 rotates relative to the fixed bracket 21, the hook 211 is always snap-fitted and limited by the hook platform 221.
[0051] It should be noted that when assembling the handheld threader 100 of this application, the rotating bracket 22 can be abutted and limited with the second cover 12 first, and then the threading rope 30 can be assembled onto the second cover 12 and one end of the threading rope 30 can be fixed to the rotating bracket 22; then, the first cover 11 can be covered with the fixing bracket 21, and finally the hook 211 on the fixing bracket 21 can be engaged with the hook platform 221 on the rotating bracket 22.
[0052] like Figure 6 As shown, in this embodiment, the number of hooks 211 is configured as two, and the two hooks 211 are symmetrically arranged with respect to the center line of the fixed bracket 21. It can be understood that in other embodiments, the number of hooks 211 may also be configured as three, four, or even more, which will not be elaborated here.
[0053] like Figure 4 , Figure 5 and Figure 8 As shown, in this embodiment, a fixing plate 23 is connected to the fixing bracket 21. The fixing plate 23 is partially disposed between the two hooks 211 to support the two hooks 211. The fixing plate 23 abuts against and limits the two hooks 211 on the side facing the hook platform 221. This ensures that the two hooks 211 can be snapped onto the hook platform 221 and ensures the stability of the assembly between the fixing bracket 21 and the rotating bracket 22. Here, a central protrusion 212 is formed on the fixing bracket 21 at the center position between the two hooks 211. Correspondingly, a limiting protrusion 231 and multiple limiting ribs 232 are formed on the fixing plate 23. The multiple limiting ribs 232 are arranged at equal intervals on the outer periphery of the limiting protrusion 231. The limiting protrusion 231 can be inserted into the central protrusion 212 and fixed with screws 210 penetrating the fixing plate 23. The fixing plate 23 also abuts against and limits the hooks 211.
[0054] like Figure 2As shown, in one embodiment, a spring clip 213 is connected to the fixed bracket 21, and the handheld threader 100 can be clamped and fixed by the spring clip 213. This allows the user to clamp and fix the handheld threader 100 to their waistband (not shown) via the spring clip 213, achieving the purpose of carrying it with them, thus facilitating the user's use of the handheld threader 100. Here, the spring clip 213 is set perpendicular to the handle 40, and specifically, the spring clip 213 can be connected to the fixed bracket 21 as a single unit, preferably using a plastic material.
[0055] like Figure 1 , Figure 3 and Figure 7 As shown, in one embodiment, a rib 222 is provided on the end face of the rotating bracket 22 away from the fixed bracket 21; the handle 40 is rotatably connected to the rib 222 via a pivot 401, thereby enabling the handle 40 to be folded on the rotating bracket 22, which facilitates the assembly of the handle 40 onto the rotating bracket 22. Here, a receiving cavity 201 is formed between the rib 222 and the rotating bracket 22; when the handle 40 is folded onto the rotating bracket 22, the handle 40 is received in the receiving cavity 201; correspondingly, the end of the handle 40 away from the pivot 401 is raised to facilitate manual operation of the handle 40, allowing the handle 40 to be manually switched from a folded state to an unfolded state.
[0056] like Figure 3 , Figure 5 and Figure 7 As shown, in one embodiment, an extension protrusion 41 is vertically connected to the handle 40, and an insertion hole 223 is formed on the rotating bracket 22, which is matched with the extension protrusion 41. When the handle 40 is folded onto the rotating bracket 22, the extension protrusion 41 can be inserted into the insertion hole 223. In this way, the extension protrusion 41 vertically connected to the handle 40 makes it easier for the user to grasp and apply force to the unfolded handle 40, thereby further facilitating the user's operation of the handheld threader 100 for threading. In addition, the insertion hole 223 of the rotating bracket 22 accommodates the extension protrusion 41 on the handle, so that the setting of the extension protrusion 41 does not affect the folding of the handle 40 on the rotating bracket 22.
[0057] like Figure 3 , Figure 5 As shown, in this embodiment, when the handle 40 is unfolded from the rotating bracket 22, the extension protrusion 41 is provided on the outside of the second cover 12, which provides a sufficiently large space for the hand to grasp the extension protrusion 41 on the handle 40 after it is unfolded. This further facilitates the hand's operation of the handheld threader 100 for threading and unthreading.
[0058] 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.
[0059] 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.
