Description
Technical field
The utility model belongs to field of exercise equipment, and in particular to a kind of anti-loosening dumbbell.
Background technology
Dumbbell is common fitness equipment in life, generally has dumbbell bar, dumbbell cake and latch segment to constitute, and latch segment is general
The both ends of dumbbell bar are threaded in, since latch segment is metal material, the dynamics tightened by hand is limited, in use,
The loose phenomenon for occurring slight is easily caused, after there is slight loosen, dumbbell cake will be relative to dumbbell bar activity, and makes
With being rotated on dumbbell bar under the action of inertia in the process, rotation can cause latch segment further to loosen, make the amplitude of loosening by
It is cumulative big, it can just be continuing with, cause inconvenient for use after the fastening that need to stop.
Utility model content
Purpose of utility model：For the deficiencies in the prior art, the utility model provides a kind of anti-loosening dumbbell.
To achieve the above object, the utility model provides a kind of anti-loosening dumbbell, including dumbbell bar, on the dumbbell bar
Two internal stops are arranged with, the internal stop outer end is equipped with the lug boss of non-cylindrical, is equipped at least on the outside of the internal stop
One dumbbell cake, dumbbell cake side is equipped with to be equipped with and internal stop outer end with the matched groove of the lug boss, the other side
Identical lug boss, the dumbbell cake outside are equipped with latch segment, and the latch segment is threadedly coupled with the dumbbell bar both ends, described
A locking cushion block is equipped between latch segment and dumbbell cake, the locking cushion block is set in the outside of the lug boss.
Preferably, the locking cushion block is rubber cushion blocks, outboard end is arranged except 4 side of the lug boss.
Preferably, being equipped with a spring between the locking cushion block and latch segment.
Preferably, the locking cushion block side opposite with latch segment is both provided with spring groove, the both ends of the spring
It is separately positioned in the spring groove.
Preferably, the section of the lug boss is in multilateral shape, crosswise or plum blossom-shaped.
Preferably, being enclosed with rubber protective layer on the outside of the dumbbell cake.
Preferably, being equipped with Anti-slip cover in the middle part of the dumbbell bar, anti-sliding burr is equipped on the outside of the Anti-slip cover.
Advantageous effect：The utility model thinks the lug boss and groove knot of cooperation by being arranged on dumbbell bar and dumbbell cake
Structure, dumbbell cake rotates during avoiding use, by the way that locking cushion block and spring structure is arranged, increases latch segment and dumbbell bar
Between connection dynamics, there is good anti-loosing effect, the phenomenon that loosening is greatly reduced during use, it is easy to use.
Description of the drawings
Fig. 1 is the structural schematic diagram of the left side of the anti-loosening dumbbell of the utility model embodiment；
Specific implementation mode
The utility model is furtherd elucidate with reference to specific attached drawing, present embodiment is with the utility model technology
Implemented under premised on scheme, it should be understood that these modes are merely to illustrate the utility model rather than limitation the utility model
Range.
As shown in Figure 1, the utility model embodiment provides a kind of anti-loosening dumbbell, which includes dumbbell bar 1 and extremely
A few dumbbell cake 2 being arranged at 1 both ends of dumbbell bar is equipped with anti-skidding to increase the frictional force of holding at the middle part of dumbbell bar 1
Set 9,9 outside of Anti-slip cover are equipped with anti-sliding burr.Floor damage is caused when placing in order to prevent, rubber is enclosed in 2 outside of dumbbell cake
Compound protective layer.Be arranged with two internal stops 3 on dumbbell bar 1, the position of internal stop 3 and dumbbell bar 1 be it is relatively-stationary, can be with
Internal stop 3 is formed or is welded and fixed with 1 integrally casting of dumbbell bar.It is equipped with lug boss 4 in 3 outer end of internal stop, lug boss 4 is cut
Face is non-cylindrical, can be multilateral shape, crosswise or plum blossom-shaped.Dumbbell cake 2 is arranged in the outside of internal stop 3, dumbbell cake 2
Side be equipped with 4 matched groove 5 of lug boss, the other side is equipped with lug boss 4 identical with 3 outer end of internal stop, outside dumbbell cake 2
Side is equipped with latch segment 6, and latch segment 6 is threadedly coupled with 1 both ends of dumbbell bar.It is matched, can be prevented with groove 5 by lug boss 4
Dumbbell cake 2 generates the phenomenon that rotation causes latch segment 6 to loosen.
In order to further increase anti-loosing effect, the utility model embodiment is additionally provided with one between latch segment 6 and dumbbell cake 2
Locking cushion block 7, locking cushion block 7 are set in the outside of lug boss 4.Locking cushion block 7 is the cushion block that rubber material may be used, by rubber
The outboard end of rubber cushion block is arranged except the side of lug boss 4 so that rubber cushion blocks can be contacted with latch segment 6, utilize rubber
Elasticity improve the threaded connection dynamics between latch segment 6 and dumbbell bar 1, can also be arranged between locking cushion block 7 and latch segment 6
One spring 8 improves the threaded connection dynamics between latch segment 6 and dumbbell bar 1, the both ends of spring 8 using the elasticity of spring
Can be fixedly connected with latch segment 6 respectively at loosening cushion block 7, can also be used other manner installation, for example, locking cushion block 7 with
The opposite side of latch segment 6 is both provided with spring groove, and the both ends of spring 8 are separately positioned in spring groove.
The utility model thinks the lug boss and groove structure of cooperation by being arranged on dumbbell bar and dumbbell cake, avoids using
Dumbbell cake rotates in the process, by the way that locking cushion block and spring structure is arranged, increases the connection between latch segment and dumbbell bar
Dynamics has good anti-loosing effect, and the phenomenon that use loosens in the process is greatly reduced, and is easy to use.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
