Description

Technical Field

[0001] This application relates to the field of wire harness knotters, and more particularly to a handheld wire rope end knotting device. Background Technology

[0002] Knotting is an essential step in medical suture knotting and fishing net repair, typically used for tissue suturing and closing fishing net thread ends. Currently, knotting must be done manually. A single knot involves making a loop, threading the thread through the loop, tightening the loop, and then repeating this structure for the top knot and triple knot.

[0003] However, since these knot-tying operations are all done by hand, traditional hand knot-tying is quite difficult in some scenarios with limited space, and there is room for improvement. Utility Model Content

[0004] To improve the convenience for operators to knot ropes in confined spaces, this application provides a handheld rope knotting device.

[0005] The handheld rope knotting device provided in this application adopts the following technical solution:

[0006] A handheld rope knotting device includes a housing. A transverse winding groove and a longitudinal winding groove are formed through the end side wall of the housing. The depth of the transverse winding groove is greater than that of the longitudinal winding groove. A rope loop fixing hook is rotatably connected inside the housing. A first driving mechanism is fixedly connected inside the housing and fixedly connected to the rope loop fixing hook. The first driving mechanism is used to drive the rope loop fixing hook to rotate toward the direction of approaching or away from the inner wall of the housing.

[0007] A slider is slidably installed inside the housing, and two grippers are rotatably installed on the slider. The two grippers are located on both sides of the longitudinal winding groove. A second driving mechanism is fixedly connected inside the housing and fixedly connected to the slider. The second driving mechanism is used to drive the two grippers to move closer to each other and slide away from the rope loop fixing hook.

[0008] By adopting the above technical solution, when using the knotting device for knotting operations, the user can align the transverse winding groove on the housing with the end of the rope, so that the rope passes through the transverse winding groove at the end of the housing. Then, the user rotates the housing so that the end of the rope is wrapped around the outer wall of the housing. After the user secures the remaining end of the rope in the longitudinal winding groove, the first drive mechanism drives the rope ring fixing hook to rotate towards the top inner wall of the housing to position the rope secured in the transverse winding groove. The second drive mechanism drives the two jaws to clamp the end of the rope while simultaneously driving the two jaws to slide away from the rope ring fixing hook, which can pull the end of the rope into the rope ring. After the first drive mechanism releases the rope ring fixing hook and the second drive mechanism drives the two jaws to reset and release the end of the rope, the knotting operation of the rope end is completed, which can improve the convenience of the user to complete the knotting operation in a confined sewing environment.

[0009] Preferably, a first shaft is fixedly connected to both sides of the rope ring fixing hook, the two first shafts are coaxially arranged, and a first insertion hole is provided through the side wall of the housing for the first shaft to pass through. The two first shafts are rotatably installed in the two first insertion holes respectively.

[0010] A connecting rod is fixedly connected to one side of the rope ring fixing hook. Second insertion holes are respectively opened through the two side walls of the housing. A second shaft is mounted above the rope ring fixing hook. The two ends of the second shaft are respectively rotatably installed in the two second insertion holes. A tension spring is detachably installed between the connecting rod and the second shaft.

[0011] The first drive mechanism includes a first electric winch with a first steel wire wound on it. A mounting rod is fixedly connected to the side of the rope loop fixing hook away from the connecting rod. The end of the first steel wire is fixedly connected to the mounting rod, and the first steel wire is located above the second shaft.

[0012] By adopting the above technical solution, the first shafts on both sides of the rope ring fixing hook enable the rope ring fixing hook body to rotate and connect inside the housing; the mounting rod enables the connection between the first steel wire and the rope ring fixing component; and the second shaft enables the installation of the tension spring. In actual use, the first electric winch tightens the first steel wire, which drives the rope ring fixing component to rotate upward to position the rope, facilitating the subsequent insertion of the rope end into the rope ring by the two grippers. Once the rope end is inside the rope ring, the first electric winch releases the first steel wire, and the tension spring rebounds, causing the rope ring fixing hook to reset and release the rope. After pulling the housing out of the rope ring, a knot can be tied at the end of the rope.

[0013] Preferably, the mounting rod has a first annular groove, and the end of the first steel wire is fixedly installed in the first annular groove.

[0014] By adopting the above technical solution, the first steel wire is fixedly installed in the first annular groove. The inner wall of the first annular groove restricts the position of the first steel wire, which can reduce the occurrence of the first steel wire falling off the mounting column.

[0015] Preferably, a rotating shaft is fixedly connected to the slider, and two limiting plates are fixedly connected to the rotating shaft. A space for two grippers to extend into is formed between the two limiting plates, and a connecting groove adapted to the rotating shaft is formed between the two grippers.

[0016] Two wedge blocks are fixedly connected to each of the two grippers, and a spring is fixedly connected between the two wedge blocks. The two wedge blocks abut against the two inner walls of the housing at both ends of the spring. Limiting holes for limiting the position of the wedge blocks are respectively opened through the two side walls of the housing. The outer side wall of the wedge block is formed with an inclined surface, and the inclined surface is inclined inward in the direction away from the rope ring fixing hook.

[0017] The second drive mechanism includes a second electric winch with a second steel wire wound on it, and the end of the second steel wire is fixedly connected to the slider.

[0018] By adopting the above technical solution, when the rope end needs to be pulled, the second electric winch tightens the second steel wire. The second steel wire pulls the slider and the two grippers to slide away from the rope loop fixing hook, and at the same time drives the wedge blocks on the two grippers to slide. Since the outer side of the wedge block is provided with an inclined surface and the two wedge blocks are provided with a spring, the two wedge blocks can compress the spring and move inward, thereby driving the two grippers to move synchronously towards the rope end until the rope end is clamped. After the knotting operation is completed, the second electric winch releases the second steel wire. Since the outer side of the wedge block is provided with an inclined surface, the elastic force generated by the spring drives the two wedge blocks to return to the two limit holes, and the two grippers release the rope end.

[0019] Preferably, the slider includes an upper mounting part and a lower mounting part. The upper mounting part and the lower mounting part are respectively provided with mounting half grooves on opposite sides. A positioning post is installed between the two mounting half grooves. The positioning post and the mounting half grooves are both arranged along the width direction of the slider. A second annular groove is provided on the positioning post. The end of the second steel wire is fixedly connected in the second annular groove. A wire hole for the second steel wire to pass through is formed between the upper mounting part and the lower mounting part.

[0020] By adopting the above technical solution, the positioning post can achieve a fixed connection between the second steel wire and the slider. The second annular groove on the positioning post can restrict the position of the second steel wire, preventing the second steel wire from separating from the positioning post.

[0021] Preferably, guide posts are fixedly connected to the opposite sidewalls of the two wedge blocks, and the two ends of the spring are coaxially sleeved on the outside of the two guide posts.

[0022] By adopting the above technical solution and setting the guide post, the deformation direction of the spring can be guided, thus extending the service life of the spring.

[0023] In summary, the handheld rope knotting device of this application has at least the following beneficial technical effects:

[0024] 1. When using the knotting device for knotting operations, the user can align the transverse winding groove on the housing with the end of the rope, so that the rope passes through the transverse winding groove at the end of the housing. Then, the user rotates the housing so that the end of the rope is wrapped around the outer wall of the housing. After the user secures the remaining end of the rope in the longitudinal winding groove, the first drive mechanism drives the rope ring fixing hook to rotate towards the inner top wall of the housing to position the rope secured in the transverse winding groove. The second drive mechanism drives the two jaws to clamp the end of the rope while simultaneously driving the two jaws to slide away from the rope ring fixing hook, which can pull the end of the rope into the rope ring. After the first drive mechanism releases the rope ring fixing hook and the second drive mechanism drives the two jaws to reset and release the end of the rope, the knotting operation of the rope end is completed. This can improve the convenience of the user in completing the knotting operation in a confined sewing environment.

[0025] 2. By setting guide posts, the deformation direction of the spring can be guided, thus extending the service life of the spring. Attached Figure Description

[0031] The following combination Figures 1-4 This application will be described in further detail.

[0032] Example

[0033] This application discloses a handheld rope knotting device. (Refer to...) Figures 1-4 It mainly includes a polygonal cylindrical shell 1. A transverse winding groove 11 and a longitudinal winding groove 12 are provided through the end side wall of the shell 1. The depth of the transverse winding groove 11 is greater than that of the longitudinal winding groove 12. A rope ring fixing hook 2 is rotatably connected inside the shell 1. A first driving mechanism is fixedly connected inside the shell 1 and fixedly connected to the rope ring fixing hook 2. The first driving mechanism is used to drive the rope ring fixing hook 2 to rotate toward the inner wall of the top of the shell 1.

[0034] It should be noted that the end of the housing 1 has an opening, the transverse winding groove 11 is arranged along the width direction of the opening plane, the longitudinal winding groove 12 is arranged along the height direction of the opening plane, and the hook body of the rope ring fixing hook 2 is arranged facing the top inner wall of the housing 1.

[0035] A slider 4 is slidably installed inside the housing 1. Two grippers 5 are rotatably installed on the slider 4. The two grippers 5 are located on both sides of the longitudinal winding groove 12. A second driving mechanism is fixedly connected inside the housing 1 and fixedly connected to the slider 4. The second driving mechanism is used to drive the two grippers 5 to move closer to each other and slide away from the rope ring fixing hook 2.

[0036] When using the knotting device to perform knotting operations, the user can align the transverse winding groove 11 on the housing 1 with the end of the rope, so that the rope passes through the transverse winding groove 11 at the end of the housing 1. Then, the user rotates the housing 1 so that the end of the rope is wrapped around the outer wall of the housing 1. After the user secures the remaining end of the rope in the longitudinal winding groove 12, the first drive mechanism drives the rope ring fixing hook 2 to rotate toward the top inner wall of the housing 1 to position the rope secured in the transverse winding groove 11. The second drive mechanism drives the two grippers 5 to clamp the end of the rope while simultaneously driving the two grippers 5 to slide away from the rope ring fixing hook 2, which can pull the end of the rope into the rope ring. After the first drive mechanism releases the rope ring fixing hook 2 and the second drive mechanism drives the two grippers 5 to reset and release the end of the rope, the knotting operation of the end of the rope is completed, which can improve the convenience of the user to complete the knotting operation in a confined sewing environment.

[0037] Reference Figure 1 , Figure 2 as well as Figure 3 The left and right sides of the rope ring fixing hook 2 are respectively fixedly connected to the first shaft 21. The two first shafts 21 are coaxially arranged. The side wall of the housing 1 is provided with a first insertion hole 13 for the first shaft 21 to pass through. The two first shafts 21 are respectively rotatably installed in the two first insertion holes 13.

[0038] A connecting rod 23 is fixedly connected to one side of the rope ring fixing hook 2. Second insertion holes 14 are respectively opened through the two side walls of the housing 1. A second shaft 22 is mounted above the rope ring fixing hook 2. The two ends of the second shaft 22 are respectively rotatably installed in the two second insertion holes 14. A tension spring 24 is detachably installed between the connecting rod 23 and the second shaft 22.

[0039] In this embodiment, the first driving mechanism is a first electric winch 3, on which a first steel wire 31 is wound. A mounting rod 25 is fixedly connected to the side of the rope loop fixing hook 2 away from the connecting rod 23. The end of the first steel wire 31 is fixedly connected to the mounting rod 25, and the first steel wire 31 is located above the second shaft 22.

[0040] The first shafts 21 on both sides of the rope ring fixing hook 2 enable the rope ring fixing hook 2 body to rotate and connect inside the housing 1; the installation rod 25 enables the connection between the first steel wire 31 and the rope ring fixing component; and the second shaft 22 enables the installation of the tension spring 24.

[0041] In actual use, the first electric winch 3 tightens the first steel wire 31, which can drive the rope ring fixing member to rotate upward to position the rope, making it easier for the two grippers 5 to drive the rope end into the rope ring. After the rope end is inserted into the rope ring, the first electric winch 3 releases the first steel wire 31, and the tension spring 24 rebounds, which can drive the rope ring fixing hook 2 to reset and release the rope. After pulling the housing 1 out of the rope ring, a knot can be tied at the end of the rope.

[0042] Reference Figure 2 The mounting rod 25 has a first annular groove, and the end of the first steel wire 31 is fixedly installed in the first annular groove. The first steel wire 31 is fixedly installed in the first annular groove, and the inner wall of the first annular groove restricts the position of the first steel wire 31, which can reduce the occurrence of the first steel wire 31 falling off the mounting post.

[0043] Reference Figure 3 A rotating shaft 41 is fixedly connected to the slider 4, and two limiting plates 42 are fixedly connected to the rotating shaft 41. A space for two grippers 5 to extend into is formed between the two limiting plates 42. A connecting groove adapted to the rotating shaft 41 is formed between the two grippers 5.

[0044] It should be noted that the two grippers 5 are made of a piece of stainless steel bent into a V shape. The two grippers 5 are the two arms of the V-shaped stainless steel material, and the connecting groove is formed between the two arms of the stainless steel material.

[0045] Two wedge blocks 51 are fixedly connected to the two grippers 5 respectively, and a spring 52 is fixedly connected between the two wedge blocks 51. The two wedge blocks 51 abut against the two inner walls of the housing 1 opposite to the two ends of the spring 52. Limiting holes 15 for limiting the position of the wedge blocks 51 are respectively opened through the two side walls of the housing 1. The outer side wall of the wedge block 51 is formed with a slope, and the slope is inclined inward along the direction away from the rope ring fixing hook 2.

[0046] The second drive mechanism is a second electric winch 6, on which a second steel wire 61 is wound, and the end of the second steel wire 61 is fixedly connected to the slider 4.

[0047] When the rope end needs to be pulled, the second electric winch 6 tightens the second steel wire 61. The second steel wire 61 pulls the slider 4 and the two grippers 5 to slide away from the rope ring fixing hook 2. At the same time, it drives the wedge blocks 51 on the two grippers 5 to slide. Since the outer side of the wedge blocks 51 is provided with an inclined surface and the two wedge blocks 51 are provided with a spring 52, the two wedge blocks 51 can compress the spring 52 and move inward, thereby driving the two grippers 5 to move synchronously towards the rope end until the rope end is clamped. After the rope end is clamped, the slider 4 continues to drive the two grippers 5 to move backward, pulling the rope end into the rope ring. After the knotting operation is completed, the second electric winch 6 releases the second steel wire 61. Since the outer side of the wedge blocks 51 is provided with an inclined surface, the elastic force generated by the spring 52 drives the two wedge blocks 51 to return to the two limiting holes 15, and the two grippers 5 release the rope end.

[0048] Reference Figure 3 and Figure 4 The slider 4 includes an upper mounting part and a lower mounting part. The upper mounting part and the lower mounting part are respectively provided with mounting half grooves on opposite sides. A positioning post 43 is installed between the two mounting half grooves. The positioning post 43 and the mounting half grooves are both arranged along the width direction of the slider 4. A second annular groove is provided on the positioning post 43. The end of the second steel wire 61 is fixedly connected in the second annular groove. A wire hole for the second steel wire 61 to pass through is formed between the upper mounting part and the lower mounting part.

[0049] The positioning post 43 can achieve a fixed connection between the second steel wire 61 and the slider 4. The second annular groove on the positioning post 43 can restrict the position of the second steel wire 61, preventing the second steel wire 61 from separating from the positioning post 43.

[0050] Reference Figure 2 Guide posts 53 are fixedly connected to the opposite sidewalls of the two wedge-shaped blocks 51, and the two ends of the spring 52 are coaxially sleeved on the outside of the two guide posts 53. The guide posts 53 guide the deformation direction of the spring 52 and extend the service life of the spring 52.

[0051] It should be noted that in this embodiment, both the first electric winch 3 and the second electric winch 6 are miniature winches, and both are fixed to the inner wall of the housing 1 by bolting. Furthermore, both the first electric winch 3 and the second electric winch 6 are existing technologies and are mainly controlled by control buttons installed on the outer wall of the housing 1.

[0052] The implementation principle of a handheld rope knotting device according to an embodiment of this application is as follows: When using the knotting device to perform a knotting operation, the user can align the transverse winding groove 11 on the housing 1 with the end of the rope, so that the rope passes through the transverse winding groove 11 at the end of the housing 1. Then, the user rotates the housing 1 so that the end of the rope is wrapped around the outer wall of the housing 1. After the user clamps the remaining end of the rope in the longitudinal winding groove 12, the first driving mechanism drives the rope ring fixing hook 2 to rotate toward the top inner wall of the housing 1 to position the rope clamped in the transverse winding groove 11. The second driving mechanism drives the two grippers 5 to clamp the end of the rope while simultaneously driving the two grippers 5 to slide away from the rope ring fixing hook 2, which can pull the end of the rope into the rope ring. After the first driving mechanism releases the rope ring fixing hook 2 and the second driving mechanism drives the two grippers 5 to reset and release the end of the rope, the knotting operation of the rope end can be completed, which can improve the convenience of the user to complete the knotting operation in a narrow sewing environment.

[0053] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application.
