Description

CROSS REFERENCE TO THE RELATED APPLICATIONS This application is based upon and claims priority to Chinese Patent Application No. 202322549894.7, filed on Sep. 19, 2023, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD The present disclosure relates to the technical field of fitness equipment, and in particular to a weight-visualized dumbbell. BACKGROUND As a fitness equipment favored by fitness enthusiasts, the dumbbell can be used to train strength of a user's arms. The dumbbell can be placed at home for its small size, such that fitness enthusiasts can take exercises without going to fitness rooms. The dumbbell typically includes a plurality of weight plates, a grab handle assembly configured for the weight plates to be mounted, and a base configured for the weight plates to be placed. The grab handle assembly includes a handle tube, a plate selection mechanism provided on the handle tube, an internal end cover, and an external end cover. For the existing dumbbell in markets, gears can be shifted by rotating the handle tube on the grab handle assembly, thereby adjusting the number of weight plates on the grab handle assembly. Labels indicating the number or the weight and in one-to-one correspondence with the gears are further marked on the existing dumbbell, such that the user knows the number or the weight of the dumbbell at the present gear when adjusting the weight plates. However, the labels of the existing dumbbell are directly marked on the outer sidewall of the internal end cover or the peripheral surface of the internal end cover. When the dumbbell is used, the labels marked on the outer sidewall of the internal end cover are worn easily. After long-time use, the labels become unclear to affect the reading experience. For the labels marked on the peripheral surface of the internal end cover, the protective cover is provided for the peripheral surface of the internal end cover to prevent the wear. Nevertheless, this structure increases the overall size of the internal end cover to some extent. SUMMARY In order to solve the problem that labels marked on an outer sidewall of an internal end cover are worn easily or a protective cover is provided for the labels marked on a peripheral surface of the internal end cover to increase a size of a dumbbell, the present disclosure provides a weight-visualized dumbbell. The preset application employs the following technical solutions to realize the weight-visualized dumbbell. A weight-visualized dumbbell includes two weight plate sets and a grab handle assembly configured to suspend and grip the weight plate sets, where the grab handle assembly includes a handle tube, an end cover assembly connected to the handle tube, and a plate selection mechanism connected to the handle tube and rotating synchronously with the handle tube; the plate selection mechanism is provided with a plurality of gears that are driven by the handle tube to rotate relative to the weight plate sets; when the plate selection mechanism rotates to different gears, different numbers of weight plates are fixedly suspended and gripped; a display mechanism is provided in the end cover assembly; the display mechanism rotates synchronously with the handle tube; the display mechanism is provided with labels that are in one-to-one correspondence with the gears of the plate selection mechanism and are each configured to display a weight of the dumbbell at a present gear; and a display opening configured for the label to be exposed is formed in the end cover assembly. According to the above technical solution, the labels are in one-to-one correspondence with the gears of the plate selection mechanism. When the plate selection mechanism is shifted to some gear by rotating the handle tube, the label of the display mechanism can display a value on the weight of the weight plates at the present gear. The label can be directly observed by a user through the display opening, thereby being simple and convenient. Since the display mechanism is provided in the end cover assembly, the label is protected by the end cover assembly, and the label is not damaged easily. Meanwhile, there is no need to additionally provide a protective cover on the end cover assembly to protect the display mechanism, thereby reducing a size of the internal end cover. Optionally, the display mechanism includes a locating disc coaxial with the handle tube and configured to rotate synchronously with the handle tube, and a display disc provided on the end cover assembly and cooperating with the locating disc; a plurality of locating recesses are uniformly formed in a circumferential direction of the locating disc; a driven toothed portion cooperating with the locating recesses is provided in a circumferential direction of the display disc; each of the locating recesses corresponds to one of the gears of the plate selection mechanism; and the label is located on the display disc. According to the above
