Description

Kettle bell Technical Field The application relates to the technical field of body-building equipment, in particular to a kettle bell. Background Kettlebells are a common training device in the fitness equipment industry and play an important role in strength training and functional training. The traditional kettlebells are usually of a fixed weight design, and a user needs to replace kettlebells with different weights when exercising with different intensities, so that the burden of the user is increased, and a large amount of storage space is occupied. In order to meet the requirement of users on the weight-adjustable kettle bell, the total weight of the kettle body is often adjusted by increasing or reducing the number of balancing weights in the kettle body, and when the balancing weights are required to be increased, the balancing weights are sleeved on a screw rod in the kettle body, and then nuts are screwed to limit all the balancing weights in the kettle body. When the balancing weight needs to be reduced, the nut is unscrewed, the balancing weight needing to be reduced is taken down from the screw rod, and then the nut is screwed down again, so that the balancing weight in the kettle body is increased or decreased. However, when the total weight of the kettle body is adjusted, the nut is required to be completely detached, and then the balancing weight is manually increased or decreased, so that time and labor are wasted, and the use experience of a user is affected. Disclosure of utility model In view of the above, the application provides a kettle bell to solve the problems that the prior kettle body needs to completely disassemble a nut and then manually increase or decrease a balancing weight when adjusting the total weight of the kettle body, which results in time and labor waste and influences the use experience of users. The application provides a kettle bell, comprising: A kettle body with an open cavity; The balance weight adjusting assembly comprises an adjusting piece and N balance weight pieces which are sequentially stacked along a first direction, wherein the opening cavity is used for accommodating the N balance weight pieces, the adjusting piece can move relative to the kettle body, and the adjusting piece is provided with M bearing parts which are distributed at intervals along the first direction, wherein N is more than or equal to 1, and M is more than or equal to 1 and less than or equal to N; The adjusting piece moves along a second direction to selectively couple j weight pieces to the kettle body, and at least a j bearing part receives a j weight selection position of the j weight pieces, wherein j is more than or equal to 1 and less than or equal to M; The adjusting member has an initial weight selection position that does not couple any weight member to the kettle body; The second direction limiting structure is provided with a locking position limiting the adjusting piece in the second direction and an unlocking position releasing the limiting of the adjusting piece in the second direction. The kettle body has the advantages that when j weight pieces are required to be connected (connected: the weight pieces connected with the kettle body are also moved along with the kettle body in the movement process of the kettle body) and are combined into a whole, the second-direction limiting structure is firstly positioned at the unlocking position, then the adjusting piece is moved to the j weight selecting position along the second direction, then the second-direction limiting structure is positioned at the locking position, at least the j weight pieces are supported by the j supporting portion, and because the N weight pieces are sequentially stacked along the first direction, all the weight pieces above the j weight pieces are supported by the j supporting portion, the j weight pieces can be supported, and the weight pieces in different numbers can be connected to the kettle body by moving the adjusting piece to different weight selecting positions, so that the increase and decrease of the weight pieces in the kettle body are realized, and the total weight of the kettle body is adjusted. According to the kettle bell provided by the application, the total weight of the kettle body can be changed by moving the regulating piece to different counterweight selection positions, no additional tools or complex disassembly and assembly steps are needed, the operation is simple and convenient, the total weight of the kettle body can be quickly regulated according to the self requirements of a user, the requirements of different training intensity are met, and the user experience is improved. In addition, after the increase and decrease of the weight parts is completed through the adjusting parts, the second-direction limiting structure is located at a locking position so as to limit the adjusting parts in the second direction, and the adjusting parts are prevented from moving along the
