Description

Technical Field

[0001] This utility model relates to the field of dumbbell equipment technology, and more specifically to a dumbbell that prevents the dumbbell disc from falling off. Background Technology

[0002] Dumbbells are an auxiliary tool for weightlifting and fitness exercises. They are simple equipment used to enhance muscle strength. The main material is cast iron, and some are covered with a layer of rubber. They are used for muscle strength training and compound muscle movement training. Patients with low muscle strength due to paralysis, pain, or long-term inactivity can use dumbbells to perform active resistance exercises to train muscle strength. However, existing dumbbell equipment still has the following shortcomings in actual use; First, in the case of dumbbells with existing technology, after the dumbbell disc is locked, the locking nut is prone to loosening and falling off the threaded section of the dumbbell during use, which causes the dumbbell disc to fall off the shaft section. In other words, the locking degree of dumbbell equipment with existing technology is not enough. Secondly, under the existing technology, when dumbbell equipment is used for a long time, the hand shaft section often accumulates some dust and impurities. If these dust and impurities are not cleaned in time, they will often contaminate the user's palms. Therefore, in order to solve the above problems, there is a need to provide a dumbbell that prevents the dumbbell disc from falling off. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a dumbbell that prevents the dumbbell disc from falling off, so as to solve the problems existing in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a dumbbell for preventing the dumbbell disc from falling off, comprising a dumbbell assembly, wherein locking components are provided at both ends of the dumbbell assembly, and a cleaning cotton ring is provided on the dumbbell assembly.

[0005] Furthermore, the dumbbell assembly includes a grip shaft section, with guard rings fixedly installed at both ends of the grip shaft section. Dumbbell discs are provided on the outer side of each guard ring. Threaded shaft sections are fixedly connected to the outer ends of the grip shaft section. The dumbbell discs are movably sleeved on the threaded shaft sections, and locking caps are threaded onto the threaded shaft sections.

[0006] Furthermore, the locking assembly includes a locking shaft section, which is fixedly connected to the outer end of the threaded shaft section. The locking shaft section has evenly distributed sliding grooves, and the sliding grooves have evenly distributed radial grooves. The bottom of each radial groove has a groove edge end, and a spring is fixedly connected to the groove edge end. The spring is sleeved in the radial groove, and a wedge block is fixedly connected to the top of the spring. The wedge block is movably sleeved in the radial groove. A hollow groove is formed at the axial position of the locking shaft section, and the hollow groove is interconnected with the radial groove. A pull rope is provided in the hollow groove. One end of the pull rope has a number of branch ropes corresponding to the wedge block. The branch rope ends are fixedly connected to the bottom of the wedge block, and a rope end block is fixedly installed at the other end of the pull rope.

[0007] Furthermore, a locking sleeve shaft is movably sleeved on the locking shaft section. The inner wall of the locking sleeve shaft is provided with a locking block corresponding to the number of sliding grooves. The locking sleeve shaft is fixedly connected to evenly distributed base columns. The base columns are movably sleeved with a movable shaft. The end of the movable shaft is fixedly connected to a locking ring. The locking ring fits with a locking cap. A compression spring is sleeved on the movable shaft. One end of the compression spring is fixedly connected to the locking ring, and the other end is fixedly connected to the base column.

[0008] Furthermore, the cleaning cotton ring is movably sleeved on the grip shaft section, and the cleaning cotton ring performs movable cleaning on the outer side of the shaft section.

[0009] The technical effects and advantages of this utility model are as follows: 1. This utility model is equipped with a locking assembly. After the locking cap is screwed into the threaded shaft section and the dumbbell disc is locked, the locking sleeve shaft is sleeved on the locking shaft section and pushed in, so that the locking block moves on the slide groove and the inclined block is squeezed into the radial groove. When the locking block passes the inclined block, the inclined block pops out and locks the locking block. At this time, the locking ring and the locking cap fit together and lock it, thereby realizing its function of preventing loosening and falling off. When it is necessary to remove the locking sleeve shaft, the inclined block is retracted in the radial groove by pulling the pull rope, so that the locking sleeve shaft can be taken out from the locking shaft section.

[0010] 2. This utility model is equipped with a cleaning cotton ring, which can clean the grip shaft section in real time by the movement of the cleaning cotton ring, thereby preventing dust and impurities on it from contaminating the user's palm. Attached Figure Description
