Abstract
The utility model provides a detachable combined dumbbell with the anti-loosening function, and belongs to the technical field of fitness equipment. The detachable combined dumbbell solves the technical problem that due to the fact that in the prior art, a nut easily disengages, the safety problem is caused. The combined dumbbell comprises a dumbbell rod and a plurality of dumbbell sheets, the end portion of the dumbbell rod is provided with a shaft shoulder and a threaded section, the dumbbell sheets are arranged on the dumbbell rod in a sleeved mode and located between the shaft shoulder and the threaded section, a nut is arranged on the threaded section in a screw joint mode, the inner side face of the nut is provided with a groove which is filled with a non-metal elastic piece, the inner end of the elastic piece abuts against the dumbbell sheets, and the outer end of the elastic piece abuts against the bottom of the groove. Due to the fact that the thickness of the elastic piece is larger than that of the groove and the elastic piece has the function of elastic deformation, the friction force between the nut and the dumbbell sheets can be enlarged, and especially, after the end face of the elastic piece is provided with an anti-skid pattern, the friction force between the nut and the dumbbell sheets is further improved, and the detachable combined dumbbell has a very good anti-loosening function.
Description
Technical field
The utility model belongs to body-building apparatus technical field, relates to a kind of dismountable dumb-bell sets.
Background technology
Dumbbell is a kind of for strengthening the simple equipment of muscle strength training.Its main material is cast iron, some outsourcing one deck rubber.Its purposes is for exercise for power, the training of muscle composite move.Because motor paralysis, pain, long-term immobilization etc. cause the low patient of muscular strength, hand-held dumbbell, can utilize the weight of dumbbell to carry out resistive drag force active movement, training muscular strength.Existing dumbbell is one, cast iron, can not carry out the adjusting of weight, and the personnel in the face of different physique, can not accomplish to take exercise as required, and versatility is poor.
In order to overcome the problems referred to above, some producers have designed dismountable dumb-bell sets, design some dismountable dumbbell plates, between dumbbell plate and dumbbell bar, by nut, fix, still, it has brought new defect, be exactly that nut ratio is easier to get loose, cause safety problem.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist for existing technology, and a kind of dismountable dumb-bell sets with locking functions is provided, and its technical problem to be solved is: nut anti-looseness how to realize dumb-bell sets.
The purpose of this utility model can realize by following technical proposal:
A kind of dismountable dumb-bell sets with locking functions, dumb-bell sets comprises a dumbbell bar and some dumbbell plates, the end of described dumbbell bar is provided with the shaft shoulder and thread segment, described dumbbell plate is socketed on dumbbell bar and between the described shaft shoulder and thread segment, on described thread segment, be bolted with nut, it is characterized in that, on the medial surface of described nut, offer cell body, in described cell body, be filled with nonmetallic elastic component, the thickness of described elastic component is greater than the degree of depth of described cell body, the inner of described elastic component is resisted against on dumbbell plate, the outer end of described elastic component is resisted against the bottom of described cell body.
In above-mentioned dismountable dumb-bell sets with locking functions, described cell body is cannelure, and described elastic component is annular ring, and annular ring is rubber parts or working of plastics.
In above-mentioned dismountable dumb-bell sets with locking functions, described cell body is square groove or bar-shaped trough, and the quantity of described cell body is one or more, and the shape of described elastic component and the shape of described cell body match.
In above-mentioned dismountable dumb-bell sets with locking functions, the inner face of described elastic component offers some anti-slip veins.
Compared with prior art, advantage of the present utility model is as follows:
This dumb-bell sets adopts nut solid dumbbell sheet, medial surface at nut is provided with after elastic component, when nut is screwed onto on dumbbell bar and when both tighten, because the thickness of elastic component is greater than the thickness of cell body, play the effect of strain, thereby can increase on the end face of the frictional force between nut and dumbbell plate, particularly elastic component and offer after anti-slip veins, further improve frictional force between the two, played good locking effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of dumb-bell sets.
Fig. 2 is the partial structurtes cutaway view of dumb-bell sets.
Fig. 3 is the structural representation of nut in dumb-bell sets.
In figure, 1 dumbbell bar; 2 dumbbell plates; 3 shaft shoulders; 4 thread segments; 5 nuts; 6 elastic components; 7 cell bodies.
The specific embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, Figure 2 and Figure 3, dumb-bell sets comprises a dumbbell bar 1 and some dumbbell plates 2, the end of dumbbell bar 1 is provided with the shaft shoulder 3 and thread segment 4, dumbbell plate 2 is socketed on dumbbell bar 1 and between the shaft shoulder 3 and thread segment 4, on thread segment 4, be bolted with nut 5, it is characterized in that, on the medial surface of nut 5, offer cell body 7, in cell body 7, be filled with nonmetallic elastic component 6, the thickness of elastic component 6 is greater than the degree of depth of cell body 7, the inner of elastic component 6 is resisted against on dumbbell plate 2, and the outer end of elastic component 6 is resisted against the bottom of cell body 7.Cell body 7 is cannelure, and elastic component 6 is annular ring, and annular ring is rubber parts or working of plastics.Cell body 7 is square groove or bar-shaped trough, and the quantity of cell body 7 is one or more, and the shape of the shape of elastic component 6 and cell body 7 matches.The inner face of elastic component 6 offers some anti-slip veins.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
