Description

Technical Field

[0001] This utility model belongs to the field of dumbbell technology, and specifically relates to a low-cost adjustable kettlebell frame structure. Background Technology

[0002] CN202321946101.9 discloses a kettlebell with a safety shift switch. Its connection structure is complex, involving multiple parts, which leads to the need for multiple sets of molds during production, greatly increasing production costs. In addition, in order to simplify the counterweight kettlebell structure, a threaded connection kettlebell main frame structure has appeared on the market. It includes a kettlebell handle, and a threaded rod is threadedly connected to the handle. The threaded rod serves as a connecting rod for connecting the counterweight. The drawback of this structure is that when installing the counterweight, the threaded rod needs to be screwed out. Since the threaded rod is long, it usually takes a long time and is inconvenient to disassemble and assemble. Utility Model Content

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A low-cost adjustable kettlebell frame structure includes a kettlebell handle base with a kettlebell handle on it and a connecting hole through the handle base. It also includes a ratchet bar that extends vertically through the connecting hole and is retractable relative to the connecting hole. A counterweight base is detachably connected to the end of the ratchet bar to support a counterweight fitted onto the ratchet bar.

[0006] It also includes a ratchet lever locking assembly, which locks the ratchet lever to the kettlebell handle seat.

[0007] Preferably, the ratchet lever locking component includes a mounting base disposed on the kettlebell handle seat, a locking block axially slidably disposed on the mounting base, a through locking hole disposed on the locking block, the top end of the ratchet lever passing through the locking hole, and an elastic element disposed between one end of the locking block and the mounting base. When locked, the side of the locking block is pressed into the pawl of the ratchet lever by the elastic element, at which time the ratchet lever cannot slide up and down. When unlocked, pressing the locking block compresses the elastic element, causing the side of the locking block to disengage from the pawl of the ratchet lever, and the ratchet lever can slide up and down.

[0008] Preferably, the mounting base includes a base plate fixed to the kettlebell handle base and a limiting plate fixed to the base plate. A sliding cavity is formed on the limiting plate, and a locking block is slidably connected in the sliding cavity. An elastic element is provided between the rear end of the locking block and the inner wall of the sliding cavity. A pressing protrusion protruding from the edge is formed on the rear end of the locking block, and an outlet is provided on the front end of the corresponding sliding cavity. The front end of the locking block abuts against the inner wall of the sliding cavity, and the pressing protrusion is placed in the outlet.

[0009] It also includes a top plate that is covered on the limiting plate;

[0010] Furthermore, the bottom plate and the top plate are respectively provided with a bottom hole and a top hole, and the pawl rod passes through the connecting hole, the bottom hole, the locking hole and the top hole in sequence.

[0011] Preferably, a first slot is provided on the rear end of the locking block, a second slot is provided on the inner wall of the sliding cavity, one end of the elastic element is placed in the first slot, and the other end is placed in the second slot.

[0012] Preferably, both the bottom plate and the top plate are provided with concave grooves, and the two concave grooves are respectively located in the vertical direction of the outlet to facilitate the pressing of the locking block.

[0013] Preferably, the kettlebell handle base has an opening located below the pressing protrusion for easy pressing of the pressing protrusion.

[0014] Preferably, the counterweight base is threaded onto the bottom end of the ratchet lever. This makes it easier to add or remove counterweights.

[0015] In summary, the present invention has the following main advantages:

[0016] This application allows you to control the pawl lever's up-and-down sliding movement by pressing the pressing protrusion to disengage the locking block from the pawl lever, eliminating the need for multiple rotations and making operation more convenient. Attached Figure Description
