Abstract
The invention relates to a dumbbell achieving free weight increasing. The dumbbell achieving free weight increasing comprises a dumbbell body. Symmetrical baffles are arranged at the two ends of the dumbbell body. The outer surfaces of the baffles are provided with annular protrusions. The inner walls of the protrusions are provided with inner threads used for being connected with built-in type weight increasing blocks. The outer surfaces of the protrusions are provided with outer threads used for being connected with external weight increasing sheets. The baffles are provided with a plurality of symmetrical screw holes which are used for being fixedly connected with weight increasing rods. The dumbbell achieving free weight increasing is provided with the inner threads connected with the built-in type weight increasing blocks, the outer threads connected with the external weight increasing sheets, and the screw holes used for being fixedly connected with the weight increasing rods, so that diverse options are provided for users to adjust the weight of the dumbbell, and the appearance of the dumbbell is not affected after weight increasing devices are added.
Description
Technical field
The present invention relates to a kind of rehabilitation restorer, specifically, is a kind of dumbbell that freely increases weight.
Background technology
Along with the raising of people's living standard, increasing people starts to pay close attention to the health of self, people can carry out body-building by motion after the leisure, and dumbbell is one of the most general fitness tool, common dumbbell can carry out adjustable dumbbell weight by weightening finish sheet, but common weightening finish sheet is mostly external weightening finish sheet, affect very much attractive in appearance, and common weightening finish sheet weightening finish amplitude is excessive, cannot play incremental effect, be easy to cause muscle damage if weightening finish amplitude is excessive, run counter to desire on the contrary.
Summary of the invention
The technical problem to be solved in the present invention is: for solving the problem of above-mentioned existence, provide a kind of dumbbell that freely increase weight, solve the attractive in appearance and device that increases weight of the external impact of the common dumbbell weightening finish device excessive problem of amplitude that increases weight.
The technical solution adopted for the present invention to solve the technical problems is: a kind of dumbbell that freely increases weight, comprise dumbbell body, dumbbell body two ends arrange symmetrical baffle plate, baffle plate outer surface is provided with annular protrusion, convex inner walls is provided with the internal thread for the built-in weightening finish piece that is threaded, convex outer surface is provided with the external screw thread for the external weightening finish sheet that is threaded, on baffle plate, offer several symmetrical for be fixedly connected with weightening finish bar screw.
Further, weightening finish has the anti-rolling device rolling for the sheet that prevents from increasing weight on sheet.
Further, dumbbell body surface is enclosed with skid resistant course.
The invention has the beneficial effects as follows, on the dumbbell that freely increases weight of the present invention, be provided with connect built-in weightening finish piece internal thread, be connected with the external screw thread of external weightening finish sheet with for be fixedly connected with weightening finish bar screw, thereby while making user's adjustable dumbbell weight, select diversification more, and it is attractive in appearance after interpolation weightening finish device, can not to affect dumbbell.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is decomposition texture schematic diagram of the present invention.
Fig. 2 is structural representation of the present invention.
1. dumbbell bodies in figure, 2. baffle plate, 3. projection, 4. weightening finish sheet, 5. screw, 6. anti-rolling device.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
The dumbbell that freely increases weight of one as depicted in figs. 1 and 2, comprise dumbbell body 1, dumbbell body 1 two ends arrange symmetrical baffle plate 2, baffle plate 2 outer surfaces are provided with annular protrusion 3, projection 3 inwalls are provided with the internal thread for the built-in weightening finish piece that is threaded, projection 3 outer surfaces are provided with the external screw thread for the external weightening finish sheet 4 that is threaded, on baffle plate 2, offer 43 symmetrical for be fixedly connected with weightening finish bar screw 5, further, weightening finish has the anti-rolling device 6 rolling for the sheet 4 that prevents from increasing weight on sheet 4, further, dumbbell body 1 is coated with skid resistant course, on the dumbbell that freely increases weight of the present invention, be provided with the internal thread that connects built-in weightening finish piece, be connected with the external screw thread of external weightening finish sheet 4 with for be fixedly connected with weightening finish bar screw 5, thereby while making user's adjustable dumbbell weight, select diversification more, and it is attractive in appearance after interpolation weightening finish device, can not to affect dumbbell.
In the time that people need to increase weight among a small circle, only need in screw, install with respect to the lighter weightening finish bar of weightening finish sheet and realize, if need to increase weight on a large scale time, can select to realize by external weightening finish sheet and built-in weightening finish piece.
Taking above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this invention technological thought, carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to claim scope.
