[0001] This utility model relates to the field of sports equipment technology, and in particular to a jump rope handle with a quick-adjustable rope length. Background Technology

[0002] Rope skipping is a full-body aerobic exercise that uses a rope as a tool and involves coordinated jumping movements. It comes in various forms (such as single rope skipping, double rope skipping, and fancy rope skipping). Its core advantage lies in its high efficiency; it can quickly raise your heart rate in a short time, helping to burn fat and strengthen your cardiovascular system. At the same time, it requires minimal space and equipment, is portable and easy to operate, making it suitable for daily exercise for people of all ages. It can also enhance limb coordination, agility, and rhythm.

[0003] Daily exercise, competitive training, or fancy rope skipping require different rope lengths, and people of different heights also have different needs for rope length. However, traditional rope skipping cannot quickly adjust the rope length and cannot meet diverse needs. Utility Model Content

[0004] The purpose of this invention is to overcome the existing defects and provide a jump rope handle with a quick-adjustable rope length, which can adjust the rope length to meet diverse needs.

[0005] The technical solution to achieve the above objective is as follows: a jump rope handle with a quick-adjustable rope length, comprising a handle rod, wherein a first bearing, a second bearing, and a third bearing are sequentially installed on the inner wall of the handle rod, a first core cylinder is tightly attached to the inner wall of the first bearing, a second core cylinder is inserted into the tail of the first core cylinder, and the two ends of the second core cylinder are respectively tightly attached to the corresponding second bearing and the third bearing, a fixed cap is threaded onto the handle rod, a sliding groove and an L-shaped limiting through groove are mirror-shaped on the front end of the inner wall of the first core cylinder, a fixed buckle is inserted into the front end of the inner wall of the first core cylinder, a limiting block is mirror-shaped on the fixed buckle, the two limiting blocks are located in the corresponding L-shaped limiting through groove, an annular protrusion is connected to the outer wall of the first core cylinder, a limiting through hole is provided on the handle rod, an anti-slip sleeve is fitted on the handle rod, a pressing block is provided on the anti-slip sleeve, and the pressing block is located inside the limiting through hole.

[0006] Preferably, each of the limiting blocks is located at the top of the L-shaped limiting groove, and the rear end of the L-shaped limiting groove is connected to the sliding groove.

[0007] Preferably, the outer surface of the annular bump is gear-shaped.

[0008] Preferably, the pressing block is located directly above the annular protrusion.

[0009] Preferably, a jump rope is inserted into the fixing buckle, and the internal slot of the fixing buckle is in contact with the jump rope.

[0010] Preferably, the sliding groove and the corresponding L-shaped limiting groove are connected.

[0011] Preferably, the annular protrusion and the inner wall of the handle rod do not contact each other.

[0012] The beneficial effects of this utility model are as follows: By pressing the pressing block on the anti-slip sleeve, the pressing block moves downward, thereby locking and securing the first core cylinder. Then, the fixing buckle is pushed downward, and the limiting block at the top of the L-shaped limiting groove enters the rear end of the L-shaped limiting groove. Then, the fixing buckle is rotated, and the limiting block at the rear end of the L-shaped limiting groove enters the sliding groove. At this time, the fixing buckle can be separated from the first core cylinder along the sliding groove. When the fixing buckle is pulled out from the first core cylinder, the jump rope inside the fixing buckle can be moved, thereby quickly adjusting the rope length to meet diverse needs.

[0021] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figure 1-7 As shown, a jump rope handle with a quick-adjustable rope length includes a handle rod 1, a first bearing 2, a second bearing 21, a third bearing 22, a first core tube 3, a second core tube 4, a fixing cover 5, and a fixing buckle 8.

[0024] Specifically, a quick-adjustable jump rope handle includes a handle rod 1. A first bearing 2, a second bearing 21, and a third bearing 22 are sequentially installed on the inner wall of the handle rod 1. A first core cylinder 3 is tightly attached to the inner wall of the first bearing 2. A second core cylinder 4 is inserted into the tail of the first core cylinder 3. The two ends of the second core cylinder 4 are respectively tightly attached to the corresponding second bearing 21 and third bearing 22. A fixing cover 5 is threaded onto the handle rod 1. By removing the fixing cover 5, the internal parts of the handle rod 1 can be removed, facilitating subsequent... Maintenance; The inner wall of the first core cylinder 3 has a sliding groove 6 and an L-shaped limiting groove 7 mirrored at the front end. A fixing buckle 8 is inserted into the inner wall of the first core cylinder 3. A limiting block 9 is mirrored on the fixing buckle 8. The two limiting blocks 9 are located in the corresponding L-shaped limiting grooves 7. An annular protrusion 10 is connected to the outer wall of the first core cylinder 3. A limiting hole 11 is provided on the handle rod 1. An anti-slip sleeve 12 is fitted on the handle rod 1. A pressing block 13 is provided on the anti-slip sleeve 12. The pressing block 13 is located inside the limiting hole 11.

[0025] Specifically, each limiting block 9 is located at the top of the L-shaped limiting through groove 7, and the rear end of the L-shaped limiting through groove 7 is connected to the sliding groove 6.

[0026] Specifically, the outer surface of the annular protrusion 10 is gear-shaped, which increases the friction between the pressing block 13 and the annular protrusion 10 and improves the fastening effect. The pressing block 13 is located directly above the annular protrusion 10. The pressing block 13 is set to press and lock the annular protrusion 10 and the first core cylinder 3. Otherwise, the first core cylinder 3 will rotate under the action of the first bearing 2 and the second bearing 21, and the fixing buckle 8 cannot be removed from the first core cylinder 3, and the rope length cannot be adjusted.

[0027] Specifically, a jump rope is inserted into the fixing buckle 8, and the internal slot of the fixing buckle 8 is in contact with the jump rope. When the fixing buckle 8 is pulled out from the first core cylinder 3, the rope length can be adjusted because the slot of the fixing buckle 8 is not pressed tightly by the inner wall of the first core cylinder 3. The sliding groove 6 is connected to the corresponding L-shaped limiting groove 7. The annular protrusion 10 does not contact the inner wall of the handle rod 1, ensuring the normal rotation of the first core cylinder 3.

[0028] Working principle: When adjusting the rope length, first press the pressing block 13 on the anti-slip sleeve 12. At this time, the pressing block 13 moves downward, thereby locking and securing the first core cylinder 3. Then push the fixing buckle 8 downward, and the limiting block 9 at the top of the L-shaped limiting groove 7 enters the rear end of the L-shaped limiting groove 7. Then rotate the fixing buckle 8, and the limiting block 9 at the rear end of the L-shaped limiting groove 7 enters the sliding groove 6. At this time, the fixing buckle 8 can be separated from the first core cylinder 3 along the sliding groove 6, so that the rope length can be quickly adjusted.

[0029] After adjusting the rope length, align the two limiting blocks 9 on the fixing buckle 8 with the corresponding sliding grooves 6, and then insert the fixing buckle 8 into the first core tube 3. Then rotate the fixing buckle 8 in the opposite direction until the fixing buckle 8 can no longer rotate. Then push the fixing buckle 8 upward, and the limiting blocks 9 will be stuck at the front end of the corresponding L-shaped limiting through groove 7. Since the front left and rear ends of the L-shaped limiting through groove 7 are restricted, no matter how the first core tube 3 rotates, the fixing buckle 8 will not separate from the first core tube 3.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
