Background technique

The work manual labor of present people is fewer and fewer, and also worse and worse, people are strong in order to improve itself for physical fitness The some sports of Kang Jinhang, often take exercises to gymnasium, and dumbbell is a kind of for increasing the letter of muscle strength exercise Single equipment, however the dumbbell of existing adjustable weight, some pieces together dumbbell plate by the way of being threadedly coupled, to reach adjusting The purpose of weight, however when people use dumbbell, the threaded connection between two dumbbell plates is easy to loosen, it some times happens that dumbbell The case where piece falls off and has one's foot squashed brings many unnecessary troubles when to people's body-building.

Utility model content

To solve the above problems, the utility model provides a kind of dumbbell convenient for regulating weight.

The utility model is achieved through the following technical solutions:

A kind of dumbbell convenient for regulating weight, including handle, the handle outside are coated with multiple rubber rings, the handle Both ends are respectively equipped with dumbbell plate, and the dumbbell plate side is fixed with fixed column, and the fixed column side is fixed with threaded post, described Groove is fixed on threaded post side, the dumbbell plate other side is fixed with fixation hole, and top is fixed in the fixation hole There is convex block, is fixed with internal screw thread in the fixation hole, the handle both ends are symmetrically fixed with the first fixation hole, and described first Top is fixed with the first convex block in fixation hole, is fixed with spiral shell in first to match with threaded post in first fixation hole Line.

Preferably, the dumbbell plate is used to be welded and fixed and be connect with fixed column.

Preferably, the diameter of the fixation hole is greater than internal thread diameter 2-4mm.

Compared with prior art, the beneficial effects of the utility model are: the utility model is convenient for the dumbbell of regulating weight, By the setting of convex block and groove, when the threaded connection of two dumbbell plates loosens, the convex block being fixed in fixation hole can be kept off Firmly threaded post prevents threaded post from falling off out of fixation hole, can effectively prevent the case where dumbbell plate falls off and has one's foot squashed hair in this way It is raw.

Detailed description of the invention

Fig. 1 is the schematic diagram of structure described in the utility model；

Fig. 2 is the part-structure side view of structure chart 1 described in the utility model；

Fig. 3 is the part-structure side view of structure chart 1 described in the utility model.

In figure: dumbbell plate 1, handle 2, fixation hole 3, the first fixation hole 3-1, convex block 4, the first convex block 4-1, internal screw thread 5, One internal screw thread 5-1, threaded post 6, fixed column 7, groove 8, rubber ring 9.

Specific embodiment

The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:

As shown in Figure 1, Figure 2, Figure 3 shows, a kind of dumbbell convenient for regulating weight, including handle 2 coat on the outside of the handle 2 There are multiple rubber rings 9,2 both ends of handle are respectively equipped with dumbbell plate 1, and 1 side of dumbbell plate is fixed with fixed column 7, described 7 side of fixed column is fixed with threaded post 6, and groove 8 is fixed on 6 side of threaded post, and 1 other side of dumbbell plate is fixed Equipped with fixation hole 3, top is fixed with convex block 4 in the fixation hole 3, and internal screw thread 5, the hand are fixed in the fixation hole 3 2 both ends of handle are symmetrically fixed with top in the first fixation hole 3-1, the first fixation hole 3-1 and are fixed with the first convex block 4-1, institute State the first internal screw thread 5-1 for being fixed in the first fixation hole 3-1 and matching with threaded post 6.

The dumbbell plate 1 is used to be welded and fixed and be connect with fixed column 7.

The diameter of the fixation hole 3 is greater than 5 diameter 2-4mm of internal screw thread.

Working principle: the utility model is convenient for the dumbbell of regulating weight in use, can be according to itself strength Power installs dumbbell plate 1, and when installing dumbbell plate 1, the groove 8 in threaded post 6 is with 4 phase of convex block fixed on 3 inner wall of fixation hole After alignment, then by pushing dumbbell plate 1 in the slide-in fixation hole 3 of threaded post 6, by rotation dumbbell plate 1 threaded post 6 and interior Screw thread 5 is threadedly coupled, and 1 installation process of dumbbell plate can be thus completed.The pine that is spirally connected between two dumbbell plates 1 sometimes When dynamic, due to there is a certain range of cavity in fixation hole 3 between convex block 4 and internal screw thread 5, so 5 pine of threaded post 6 and internal screw thread It moves after falling off, threaded post 6 can stay in the cavity between convex block 4 and internal screw thread 5, and threaded post 6 can arbitrarily rotate in cavity, And threaded post 6 is not easy to fall off out of fixation hole 3 in this way, and only the groove 8 in threaded post 6 is with 4 phase of convex block in fixation hole 3 The connection between two dumbbell plates 1 could be separated after alignment, and it is de- to effectively reduce people's dumbbell plate when using dumbbell in this way The case where falling, the case where effectively preventing dumbbell plate from falling off and having one's foot squashed.And due to the rubber ring being arranged on handle 2 9, when using dumbbell body-building, the dumbbell in hand is not easy to slip out of the hand to be fallen people, effectively raises the security performance of dumbbell.

The basic principles and main features and advantage of the utility model have been shown and described above.The technical staff of the industry It should be appreciated that the present utility model is not limited to the above embodiments, the above embodiments and description only describe this The principle of utility model, on the premise of not departing from the spirit and scope of the utility model, the utility model also has various change And improvement, these various changes and improvements fall within the scope of the claimed invention.The utility model requires protection scope It is defined by the appending claims and its equivalent thereof.
