Quick adjusting dumbbell and dumbbell suite

Abstract

The invention relates to a fast adjusting dumbbell. The fast adjusting dumbbell comprises a dumbbell body and dumbbell pieces attached to two ends of the dumbbell body in an accumulative mode, wherein the dumbbell body comprises a holding rod, a planetary gear system and a telescopic rod, the telescopic rod stretches out and draws back through rotation of the holding rod and transmission of the planetary gear system, then the number of the dumbbell pieces is adjusted, operation is convenient, and implementation is easy; flange transmission parts are fixedly assembled at the two ends of the holding rod, the planetary gear system comprises an outer shell, a planetary gear mechanism is arranged in a closed mode through the installation mode that the flange transmission parts are connected with the outer shell, and the situation that work of the planetary gear mechanism is affected by dust accumulation is prevented; by setting a load-bearing iron ring in the planetary gear system, the effects of bearing and limiting the planet carrier are achieved, and the heavy dumbbell pieces are prevented from influencing the structural strength of the planetary gear system.

Description

technical field [0001] The invention relates to the field of fitness equipment, in particular to a dumbbell capable of rapidly adjusting the number of dumbbell plates, and a dumbbell set including a dumbbell and a dumbbell rack. Background technique [0002] As a commonly used fitness equipment, dumbbells are loved by all kinds of fitness enthusiasts. Existing adjustable dumbbells, such as the most common nut locking type, require the user to remove or install the dumbbell pieces one by one and then lock them with a wrench, which is cumbersome to use. In order to facilitate the adjustment of the dumbbell plates, as proposed in the patent with the publication number CN111450475, it utilizes a planetary gear mechanism to drive telescopic rods to adjust the number of dumbbell plates. However, in this patent, the internal teeth of the planetary gear mechanism are selected The ring is exposed, and the driving force is input by manually turning the inner ring gear.

Existing adjustable dumbbells, such as the most common nut locking type, require the user to remove or install the dumbbell pieces one by one and then lock them with a wrench, which is cumbersome to use

In order to facilitate the adjustment of the dumbbell plates, as proposed in the patent with the publication number CN111450475, it utilizes the planetary gear mechanism to drive the expansion rod to realize the adjustment of the number of dumbbell plates. However, in this patent, the internal teeth of the planetary gear mechanism are selected The ring is exposed, and the driving force is input by manually turning the inner ring gear. Since the inner ring gear needs to be exposed, the sealing of the planetary gear mechanism is poor, and dust is easy to enter during use, which will reduce the life and reliability of the planetary gear mechanism. Moreover, the operation method of manually toggling the inner ring gear is relatively cumbersome, and it is not easy for the user to apply force
