Description

Technical Field

[0001] The utility model relates to the field of fitness equipment, in particular to a quick-insertion dumbbell. Background Art

[0002] Fitness equipment is often divided into two categories according to the number of training functions: single-function and comprehensive multi-function. Commonly used ones include rowing machines, fitness bikes, steppers, treadmills, waist beautification machines, etc., while arm exercises require the use of dumbbell-type equipment.

[0003] There are two types of existing dumbbells, one is an integrated dumbbell, and the other is a combined dumbbell. The combined dumbbell adopts a bolt insertion connection method to install the weight block, but the bolt connection method is used to fix the dumbbell weight block, which is easy to loosen and fall off from the outside of the bolt, and once the force is lost during use, the dumbbell is easy to slip. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the dumbbell counterweight is fixed by bolt connection, which is easy to become loose and fall off from the outside of the bolt, and the dumbbell may slip off once the force is lost during use.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a quick-insert dumbbell, including a handle, wherein both ends of the handle are threadedly connected with a screw rod, and a weighting plate is arranged on the outside of the screw rod. There are a total of multiple groups of the weighting plates arranged in a linear array, a slot is provided on one side of the weighting plate, and the slot is embedded in the outside of the screw rod. There are a total of two groups of embedding openings arranged symmetrically, and an embedding block is fixedly connected to the side of the weighting plate away from the embedding opening, and the embedding block is clamped inside the embedding opening.

[0006] The above technical solution realizes that the weighting sheet is first engaged on the outside of the screw rod, and then the embedding block is embedded in the embedding opening, thereby preventing the weighting sheet from slipping out therebetween, thus solving the problem of loosening and falling off caused by fixing with bolts in the past.

[0007] The utility model is further configured such that the weight plate is abutted against an outer counterweight block on the side away from the handle, the outer counterweight block is also provided with an embedding opening and an embedding block, one side of the outer counterweight block is provided with a taking groove, and there are two groups of the taking grooves which are symmetrically arranged.

[0008] The utility model is further configured such that the embedded block is abutted against a counterweight baffle on the side away from the outer counterweight block, the counterweight baffle is fixedly connected to both ends of the handle, an embedding opening is opened on the side of the handle close to the weight plate, and a fixing component is arranged on the outside of the handle.

[0009] The utility model is further configured that the fixing assembly comprises a limiting sleeve, the limiting sleeve is fixedly connected to the outside of the handle near one end, and the outside of the limiting sleeve is fixedly connected to a fixing rope.

[0010] The above technical solution allows the fixing rope to be wrapped around the hand during use, with one side of the hand pressed against the side of the limiting sleeve for fixing, thereby solving the problem of danger caused by loss of force when directly holding the outside of the handle in the past, and improving safety during use.

[0011] The utility model is further configured such that a winding rod is wound around one end of the fixing rope away from the limiting sleeve, the outside of the winding rod is fixedly connected to a connecting shell, the fixing rope is arranged inside the connecting shell, and a positioning component is arranged on the side of the winding rod away from the connecting shell.

[0012] The utility model is further configured that a stretching rod is fixedly connected to one side of the winding rod, an adjusting shell is slidably connected to the outside of the stretching rod, and the adjusting shell is fixedly connected to the inside of the handle.

[0013] The utility model is further configured that the positioning assembly comprises a rotating block, the rotating block is fixedly connected to one end of the stretching rod away from the winding rod, and a locking piece is fixedly connected to the outside of the rotating block.

[0014] The utility model is further configured that the engaging pieces have a total of multiple groups arranged in a circular array outside the rotating block, the engaging pieces are engaged with engaging blocks outside, and the engaging blocks are fixedly connected to a side of the adjusting shell away from the stretching rod.

[0015] The above technical solution realizes that the locking piece and the rotating block are restricted by the locking block, thereby locking and preventing the fixing rope from loosening, solving the problem that the hands are prone to slipping due to sweating when only the fixing rope is wrapped around the hands, and improving the fixing effect.

[0016] The beneficial effects of the utility model are as follows:

[0017] The utility model can insert the weight plate during use, allow the embedding block to embed into the embedding opening of the weight baffle, then insert the outer weight block, allow the embedding block to embed into the embedding opening of the weight plate, thereby fixing the outer weight block, then turn the screw rod into the handle to complete the installation, the user can control the winding of the fixing rope through the connecting shell, the locking piece is locked on the outside of the locking block to prevent slipping, the problem of loosening and falling caused by the use of a single bolt structure in the past, and the handle is easy to slip from the user's hand when the force is lost during normal use, thereby improving the safety during use.
