Description

Simple and easy and quick assembly type adjustable dumbbell Technical Field The utility model relates to the technical field of dumbbell equipment, in particular to a simple and quick-assembly type adjustable dumbbell. Background In the prior art, the dumbbell is divided into two types, one type is formed by integrally forming a dumbbell rod and a dumbbell sheet, the weight of the dumbbell is not adjustable, along with the gradual improvement of the requirement of a user on strength, a plurality of sets of dumbbell with different weights are purchased correspondingly, the cost is high, the occupied space is large, the other type is formed by detachably connecting the dumbbell rod and the dumbbell sheet through bolts, and the dumbbell sheets with corresponding quantity are arranged at the two ends of the holding rod according to actual requirements, and meanwhile, the length of the dumbbell rod is required to be adjusted, so that the operation is troublesome. Chinese patent No. CN222218525U discloses a novel adjustable dumbbell, by grab handle and the weight of grab handle both sides constitute, wherein, the weight is by dumbbell piece group as weight core, carries out spacingly through positioning frame, can effectively solve dumbbell piece group and take place the problem that rocks easily, cooperates through locating pin and the mounting hole on the positioning frame and dumbbell piece unit relocation hole simultaneously, just can carry out the increase/reduction of dumbbell piece unit through simply carrying out the plug of locating pin, realizes the weight gain/weight reduction purpose of dumbbell. However, the dumbbell with adjustable effect has the following disadvantages when assembled in use: 1. Firstly, a grab handle is required to be sleeved outside a connecting rod and positioned in the middle, then the dumbbell piece group is fixedly arranged in a positioning frame through a positioning pin to form a heavy hammer, and when the dumbbell piece group is integrally assembled, as the dumbbell piece group is arranged on the connecting rod and is fixed by using the positioning pin, side plates on two sides are fixedly arranged on the connecting rod and positioned on two sides of the dumbbell piece group, the mounting steps are more complicated, parts are more, a rapid effect cannot be generated during assembly, and the dumbbell piece group is time-consuming and labor-consuming for a user; 2. Secondly, the adjustable dumbbell is intended for exercise use by the user, but is relatively complex to manufacture and process due to its relatively large number of structural features, which undoubtedly increases the purchase costs. Disclosure of utility model The utility model aims to provide a simple and quick-assembly type adjustable dumbbell, which solves the problem that the dumbbell can be quickly assembled during adjustment and assembly and reduces the purchase cost. The technical scheme is that the simple and quick assembly type adjustable dumbbell comprises a handle, side baffle plates, dumbbell pieces and a fixing knob, wherein the cross section of the dumbbell piece is equal to that of the side baffle plates, the side baffle plates are symmetrically and fixedly arranged on two sides of the handle respectively, a threaded hole is formed in the center of each side baffle plate, the threaded hole penetrates through each side baffle plate and extends to the inside of the handle, and a screw is fixedly arranged on the fixing knob and embedded into the threaded hole to enable the screw to rotate so as to form threaded connection between the fixing knob and the side baffle plates. Preferably, the side parts of the side baffle plates are symmetrically provided with a plurality of dumbbell plates, the centers of the dumbbell plates are provided with jacks, the side parts of the dumbbell plates at the outermost sides are provided with fixed knobs, and screws on the fixed knobs penetrate through the jacks on the dumbbell plates and are matched with the threaded holes, so that a plurality of dumbbell plates are fixedly arranged between the fixed knobs and the side baffle plates. Preferably, the surface of the handle is provided with anti-skidding rolling patterns. Preferably, the surface of the fixed knob is also provided with anti-skid rolling patterns. Preferably, the weight marks are arranged on the surfaces of the dumbbell pieces, and the corresponding thicknesses of the dumbbell pieces with different weights are different.
