[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0045] See Figures 3-8 This utility model discloses a jump rope handle for preventing the jump rope from falling off, comprising:
[0046] The handle body 1 is provided with a rotating head 2, the rotating head 2 is provided with a mounting hole 203 at the top end, a first through hole 201 and a second through hole 202 are arranged on the outer side wall of the rotating head 2 at intervals, and the first guide rib plate 204 and the second guide rib plate 205 are arranged on the two sides of the rotating head 2 respectively corresponding to the positions between the first through hole 201 and the second through hole 202;
[0047] The rope pressing head 3 is arranged in the mounting hole 203 and is connected with the first guide rib plate 204 and the second guide rib plate 205 in a sliding manner, the opposite two side walls of the rope pressing head 3 are provided with a first rope passing limiting groove 301 and a second rope passing limiting groove 302, the lower groove walls of the first rope passing limiting groove 301 and the second rope passing limiting groove 302 are provided with a first friction protrusion 303 matched with the skipping rope, the rope pressing head 3 is pressed downward, and the first rope passing limiting groove 301 and the second rope passing limiting groove 302 are respectively matched with the first through hole 201 and the second through hole 202;
[0048] The first guide rib plate 204 is provided with a rope clamping groove 2041, and the upper and lower groove walls of the rope clamping groove 2041 are provided with a second friction protrusion 20411 matched with the skipping rope, the second friction protrusion 20411 is made of high-friction silicone material with a Shore hardness of 60A-70A
[0049] It should be noted that when the rope pressing head 3 is pressed and released, the rope body is in an S-shaped through hole and limiting groove and is clamped into the rope clamping groove, and the second friction protrusion and the first friction protrusion form a multi-point friction locking, that is, the handle mainly increases the friction between the rope body of the skipping rope and the rope clamping groove through the second friction protrusion 20411 and the first friction protrusion 303, and the second friction protrusion 20411 and the first friction protrusion 303 clamp the rope body upward and downward, so that the skipping rope is not easy to be pulled out of the rotating head, the stability of the connection between the skipping rope and the rotating head is realized, and the use experience of the skipping rope is improved.
[0050] It should be further noted that the second friction protrusions 20411 on the upper and lower groove walls of the rope clamping groove 2041 are staggered, the height of the second friction protrusion 20411 is 0.5-1.0 mm, the distance between the adjacent two second friction protrusions 20411 is 0.8-1.2 mm, and each second friction protrusion 20411 is provided with a convex rib 204111 or a sharp tooth for embedding the skipping rope, or the second friction protrusions 20411 on the upper and lower groove walls of the rope clamping groove 2041 are only one, each second friction protrusion 20411 is provided with a convex rib 204111 or a sharp tooth for embedding the skipping rope, and the specific structure is shown in Figure 6As shown, due to the setting of the convex edges 204111 or the sharp teeth, during the process of the rope body of the rope being clamped into the rope clamping groove, the convex edges 204111 or the sharp teeth can be embedded into the rope body or tightly in frictional contact with the rope body, so that the rope body is more difficult to be pulled out of the rope clamping groove.
[0051] Again referring to Figure 6 As shown, in another embodiment, the rope clamping groove 2041 is a trapezoidal clamping groove, and the upper and lower groove walls of the rope clamping groove 2041 are both rope clamping inclined surfaces 20412 which are arranged to be inclined from the groove opening to the groove bottom of the rope clamping groove 2041, and the inclination angle is 15°-30°. The width of the groove bottom of the rope clamping groove 2041 is 10%-20% smaller than the diameter of the rope body, so as to force the rope body to be tightly embedded into the second friction convex after being pressed. That is, the width of the rope clamping groove 2041 is larger at the groove opening, so as to facilitate the rope to be clamped into the rope clamping groove 2041, and the width of the rope clamping groove 2041 gradually decreases from the groove opening to the groove bottom, so that after the rope body of the rope is clamped into the rope clamping groove 2041, when the rope is jumped, the rope will gradually move to the direction of the groove bottom of the rope clamping groove 2041 under the action of the dragging force and be clamped again. Therefore, through the setting of the rope clamping inclined surfaces 20412, the stability of the connection between the rope and the rotating head can be improved again, and the rope is more difficult to be pulled out.
[0052] In one embodiment, again referring to Figure 7 The rope pressing head 3 comprises:
[0053] The pressing column 31 is located in the mounting hole 203, and the pressing column 31 is in sliding connection with the first guide rib plate 204 and the second guide rib plate 205 in an up-down manner. Opposite side walls of the pressing column 31 are both provided with a first rope passing limiting slot 301 and a second rope passing limiting slot 302.
[0054] The spring 32 is fixedly connected to the lower end of the pressing column 31 at one end, and abuts against the hole bottom surface of the mounting hole 203 at the other end.
[0055] It should be noted that through the setting of the spring 32, when the pressing column 31 moves downward and the rope passing is completed, the compressed spring can push the pressing column 31 upward to move upward, so that the rope body located in the rotating head part is in S-shaped bending, that is, the rope body located in the first rope passing limiting slot and the second rope passing limiting slot is bent relative to the rope body located in the first through hole and the second through hole. That is to say, the rope body is not in straight line through the first through hole and the second through hole, but is in curved through, so that the rope is not easy to be pulled out of the first through hole and the second through hole, and then the end part of the rope is fixed again.
[0056] In one embodiment, two guide limiting protrusions 311 are spaced apart on both sides of the pressing column 31, the two guide limiting protrusions 311 on one side are respectively slidingly limited on both sides of the first guide rib plate 204, the two guide limiting protrusions 311 on the other side are respectively slidingly limited on both sides of the second guide rib plate 205, and the top end faces of the two guide limiting protrusions 311 on the same side can respectively abut the upper holes of the first through hole 201 and the second through hole 202.
[0057] It should be noted that the up and down movement of the pressing column 31 can be guided by the guide limiting protrusions 311, so that the pressing column 31 will not deviate and move, thereby ensuring that the first rope passing limiting notch 301 and the second rope passing limiting notch 302 are respectively positionally corresponding to the first through hole 201 and the second through hole 202, which facilitates rope passing.
[0058] It should also be noted that, referring to Figure 8 , the hole bottom of the mounting hole 203 is fixed with a spring limiting column 4, and the spring 32 is sleeved on the spring limiting column 4. In this way, the spring limiting column limits the spring, avoiding problems such as bending and positional deviation of the spring during pressing or rebounding, and ensuring that the pressing column can normally move downward and upward.
[0059] In one embodiment, the upper end of the pressing column 31 is fixed with a pressing cap 33. In this way, the user directly presses the pressing cap to press the pressing column downward, which is convenient and labor-saving, and the operation is more comfortable.
[0060] As described above, when passing the rope, the pressing cap 33 is pressed downward, at which time the spring 32 is compressed, and the first rope passing limiting notch 301 and the second rope passing limiting notch 302 on the pressing column 31 are respectively positionally corresponding to the first through hole 201 and the second through hole 202 on the rotating head 2. Then, the rope end is sequentially passed into the first through hole 201→the first limiting notch 301→the rope clamping groove 2041→the second limiting notch 302→the second through hole 202. The pressing head 3 is released, the spring 32 pushes the pressing head 31 to move upward, forcing the rope body to form an S-shaped bending in the limiting notch and the through hole, at which time:
[0061] The rope body is guided to slide to the groove bottom by the rope clamping inclined surface 20412 of the rope clamping groove 2041, and the second friction protrusion 20411 is embedded into the surface of the rope body;
[0062] The first friction protrusion 303 presses the lower surface of the rope body to form a bidirectional locking, and the bending angle of the rope body reaches 120°-150°, and the friction resistance is further increased through structural deformation.
[0063] The effect of the handle is:
[0064] 1. The trapezoidal clamping groove and the multi-stage friction protrusion form a triple locking, which completely solves the problem of rope falling off;
[0065] 2. Spring reset design makes installation operation more convenient, and the spring reset drives the pressing column to move up, increases the bending angle of the rope body inside the rotating head by 20%-40%, further increases the friction contact surface of the rope body and the rotating head, and realizes dynamic enhancement of locking force;
[0066] 3. Specific parameter limitation (such as inclination angle, protrusion size) ensures that the technical solution can be implemented industrially.
[0067] Test example: using P-grade C skipping rope with a diameter of 4 mm, the handle can withstand a longitudinal tensile force of 50 N or more without loosening, while the traditional handle fails at 15 N.
[0068] Therefore, compared with the traditional handle, the skipping rope handle of the present application has the advantages of strong connection stability between the skipping rope and the handle, not easy to loosen, and improved user experience.
[0069] The embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts of each embodiment can be referred to each other. For the device disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple, and the related parts can be referred to the method part.
