[0042] In the pull tab in the prior art, the connecting knot of the rope pan is easy to loosen, causing the rope pan and the connecting piece to be easily separated, affecting the user experience.

[0043] The following is a preferred embodiment of a slider provided by the present invention that can solve the above technical problems.

[0044] Please refer to Figure 1 The preferred embodiment of the present utility model provides a slider, which includes a base 2 and a pull tab 1 for preventing the rope from falling off.

[0045] Please refer to Figure 1 、 Figure 3 and Figure 4The rope-wrapped pull tab 1 for preventing the rope from falling off comprises a connecting piece 11, a rope wrapped 12 and a sleeve 13. One end of the connecting piece 11 is connected to the base 2, and the other end is provided with a fixing hole 111. The rope wrapped 12 is formed by folding a rope in half, passing it through the fixing hole 111 and tying a knot. A first connecting knot 121 is provided at one end of the rope wrapped 12 located at the fixing hole 111. The first connecting knot 121 is used to connect the rope wrapped 12 and the other end of the connecting piece 11. The sleeve 13 is provided with a through-hole 131. The rope wrapped 12 is passed through the through-hole 131. The sleeve 13 is movably provided on the rope wrapped 12 adjacent to the first connecting knot 121. The first connecting knot 121 is limited between the other end of the connecting piece 11 and the sleeve 13 to prevent the first connecting knot 121 from loosening.

[0046] When the pull tab 1 and slider for preventing the rope from falling apart of the present invention are in normal use, the sleeve 13 is arranged adjacent to the first connecting knot 121 to cooperate with the other end of the connecting piece 11 to limit the first connecting knot 121 so that the first connecting knot 121 will not loosen, thereby making it difficult for the rope 12 to separate from the connecting piece 11. When it is necessary to remove the rope 12, the sleeve 13 is moved along the rope 12 in a direction away from the first connecting knot 121, thereby opening the first connecting knot 121 and separating the rope 12 from the connecting piece 11. When the pull tab 1 and slider for preventing the rope from falling apart of the present invention are in normal use, the sleeve 13 can ensure that the first connecting knot 121 cannot fall apart, thereby making it difficult for the rope 12 to separate from the connecting piece 11, effectively improving the user experience.

[0047] Please refer to Figure 1 and Figure 4 , the set 13 is made of rubber or plastic. The rope 12 is interference-pierced in the through-hole 131. With this structure, in the absence of a large external force, the set 13 can be fixed adjacent to the first connecting knot 121, and is not easily displaced relative to the rope 12. The structure of the set 13 is simple and easy to process and prepare. Other embodiments may provide a screw on the circumference of the set 13, and by rotating the screw toward the inside of the set 13, the rope 12 can be tightened by the screw, thereby fixing the set 13 adjacent to the first connecting knot 121. If the set 13 needs to be moved, the screw will be rotated toward the outside of the set 13 to separate the screw from the rope 12.

[0048] Please refer to Figure 1 and Figure 2 The end of the rope span 12 away from the connecting piece 11 is provided with a second connection knot 122, and the sleeve 13 is limited between the first connection knot 121 and the second connection knot 122. When the sleeve 13 moves away from the first connection knot 121, the sleeve 13 can be limited to prevent the sleeve 13 from being separated from the rope span 12, eliminating the trouble of the rope span 12 being inserted into the through hole 131 again. At the same time, the two branch ends of the rope span 12 can be tied together for easy use.

[0049] Please refer to Figure 2 and Figure 4 The sidewall of the through hole 131 is circumferentially provided with a receiving groove 132. The receiving groove 132 is located in the through hole 131 at one end near the second connection knot 122 and is used to receive and squeeze the second connection knot 122. The sleeve 13 can be pulled to the second connection knot 122 and received in the receiving groove 132. The sidewall of the receiving groove 132 squeezes the second connection knot 122, thereby preventing the second connection knot 122 from loosening and shielding the second connection knot 122, which can also improve the aesthetics.

[0050] Please refer to Figure 4 The receiving groove 132 has an annular wall 1321 connected to the side wall of the through-hole 131, and the inner circle of the annular wall 1321 extends away from the first connecting knot 121. This structure increases the structural strength of the sleeve 13 at the annular wall 1321. When the sleeve 13 is pulled away from the first connecting knot 121, the second connecting knot 122 is less likely to enter the through-hole 131 from the receiving groove 132, thereby preventing the sleeve 13 from being separated from the rope 12.

[0051] The method of using the slider of the preferred embodiment of the utility model is as follows:

[0052] During normal use, the sleeve 13 is positioned on the rope 12 adjacent to the first connection knot 121 to cooperate with the other end of the connecting piece 11 to retain the first connection knot 121, thereby preventing the first connection knot 121 from loosening and thus preventing the rope 12 from separating from the connecting piece 11. The sleeve 13 can also be pulled to the second connection knot 122 and accommodated in the receiving groove 132. The sidewalls of the receiving groove 132 squeeze the second connection knot 122, thereby preventing the second connection knot 122 from loosening and shielding the second connection knot 122, thereby improving the aesthetics.

[0053] When the rope pan 12 needs to be removed, the kit 13 is moved along the rope pan 12 in a direction away from the first connection knot 121 , so that the first connection knot 121 can be opened, and the rope pan 12 is separated from the connecting piece 11 .

[0054] This completes the method for using the slider of the preferred embodiment.

[0055] Please refer to Figure 5 、 Figure 6 and Figure 7The difference between the puller provided by the second preferred embodiment of the utility model and the first embodiment is that the sleeve set 13 is provided with two, which are a first sleeve set 133 and a second sleeve set 134, the first sleeve set 133 is movably arranged at the first connecting knot 121, and the second sleeve set 134 is arranged at the second connecting knot 122. The first connecting knot 121 can be prevented from loosening, the second connecting knot 122 can be accommodated, and the second connecting knot 122 can be prevented from loosening.

[0056] Please refer to Figure 6 and Figure 7 The side wall of the accommodating groove 132 of the second sleeve set 134 is provided with an annular limiting ring 1341, which is located at one end of the accommodating groove 132 of the second sleeve set 134 away from the first connecting knot 121, and the limiting ring 1341 is used for limiting the second connecting knot 122 in the accommodating groove 132. The limiting ring 1341 can prevent the second sleeve set 134 from being taken out from the mouth of the accommodating groove 132 away from the first connecting knot 121.

[0057] Please refer to Figure 7 The inner diameter of the limiting ring 1341 gradually increases from the end close to the connecting sheet 11 to the end away from the connecting sheet 11, so that the second connecting knot 122 can easily pass through the limiting ring 1341 and enter the accommodating groove 132.

[0058] Please refer to Figure 7 Along the axis of the perforation 131, the side wall of the accommodating groove 132 of the second sleeve set 134 gradually thickens from the middle to the two ends, and is arc-shaped. The side wall of the accommodating groove 132 is thicker at the two ends, so that the structural strength of the two places is larger, and the second connecting knot 122 is not easy to be separated from the accommodating groove 132 at the two openings of the accommodating groove 132.

[0059] The other structures of the embodiment are similar to those of the first embodiment, and will not be described here.

[0060] The anti-loose rope puller and puller of the utility model, when normally used, the sleeve set is arranged adjacent to the first connecting knot to cooperate with the other end of the connecting sheet, limits the first connecting knot, so that the first connecting knot cannot be loosened, so that the rope is not easy to be separated from the connecting sheet. When the rope needs to be removed, the sleeve set is moved along the rope away from the first connecting knot, so that the first connecting knot can be opened, and the rope is separated from the connecting sheet. The anti-loose rope puller and puller of the utility model, when normally used, can ensure that the first connecting knot cannot be loosened, so that the rope is not easy to be separated from the connecting sheet, and the user experience is effectively improved.

[0061] To sum up, although the present invention has been disclosed as above in terms of preferred embodiments, the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent substitutions or changes based on the concept of the technical solution of the present invention, should be covered by the scope of protection of the present invention.
