Abstract
The invention discloses a kind of type variable dumbbells, it includes two dumbbell heads and a connecting rod, two dumbbell heads are connected to the both ends of connecting rod, the both ends of connecting rod pass through screw thread respectively and are detachably connected with two dumbbell heads, card slot is respectively equipped at the top of two dumbbell heads, buckle is connected separately in the both ends of the connecting rod, and two buckle bottom can be come out from connecting rod internal stretch, when the connecting rod is separated with two dumbbell heads, the bottom of two buckles is connected in respectively in the corresponding card slot of two dumbbell heads, realizes the transformation of dumb-bell shape attitude.Traditional dumbbell has been carried out column transformation by the present invention, so that dumbbell becomes two kinds of detachable structures by a kind of structure of script, let us is when with dumbbell body-building, on the basis of not increasing cost, not only increases alternative, also increases interest.
Description
Technical field
The present invention relates to dumbbell field more particularly to a kind of type variable dumbbells.
Background technique
Many people can be very interested in body-building at present, and people have also increasingly understood that exercise makes one strong；So very much
People can select to buy some fitness equipments, be used to body-building at odd times, dumbbell is also one of.
Dumbbell is a kind of for enhancing the simple equipment of muscle strength training, its main material is cast iron, some outsourcings
One layer of rubber, its purposes are for exercise for power, the training of muscle composite move.Because of motor paralysis, pain, long-term immobilization etc.
Lead to the patient that muscular strength is low, hold dumbbell, carries out resistive drag force active movement, training muscular strength, dumbbell using the weight of dumbbell
Single muscle can be trained；Such as increase weight, then need the coordination of multiple muscle, also can be used as a kind of muscle composite move training.
But the dumbbell of ours currently on the market, basic structure is single, and operation is single, in use process, can be easy to make
At tired, to lose the interest for continuing body-building, enthusiasm is caused to reduce.
Summary of the invention
The purpose of the present invention is to provide a kind of type variable dumbbells of changeable form.
To achieve the above object, the invention adopts the following technical scheme:
A kind of type variable dumbbell, including two dumbbell heads and a connecting rod, two dumbbell heads are connected to the both ends of connecting rod,
The both ends of the connecting rod pass through screw thread respectively and are detachably connected with two dumbbell heads, are respectively equipped with card at the top of two dumbbell heads
Slot is connected separately with buckle in the both ends of the connecting rod, and the bottoms of two buckles can come out from connecting rod internal stretch, described
When connecting rod is separated with two dumbbell heads, the bottom of two buckles is connected in respectively in the corresponding card slot of two dumbbell heads, realizes dumb-bell shape
The transformation of attitude.
The connecting rod is made of the body of rod that two axial threads connect together.
By being welded with threaded block inside the connecting rod, the upper end of buckle is threadedly coupled with threaded block.
The invention adopts the above technical scheme, has the advantages that traditional dumbbell has been carried out column and changed by the present invention
It makes, so that dumbbell becomes two kinds of detachable structures by a kind of structure of script, let us is not increasing when with dumbbell body-building
On the basis of addition sheet, alternative is not only increased, also increases interest.
Detailed description of the invention
The present invention is described in further details below in conjunction with the drawings and specific embodiments:
Fig. 1 is the schematic diagram under dumbbell normal morphology of the present invention；
Fig. 2 is the schematic diagram under dumbbell another kind form of the present invention；
Fig. 3 is the schematic diagram that buckle is connect with connecting rod.
Specific embodiment
As shown in one of Fig. 1-3, the present invention includes a kind of type variable dumbbell, including two dumbbell heads 1 and a connecting rod 2,
Two dumbbell heads 1 are connected to the both ends of connecting rod 2, and the both ends of the connecting rod 2 pass through screw thread and two dumbbell heads 1 respectively
It being detachably connected, the top of two dumbbell heads 1 is respectively equipped with card slot 3, it is connected separately with buckle 4 in the both ends of the connecting rod 2,
And two the bottom of buckle 4 can be come out from 2 internal stretch of connecting rod, when the connecting rod 2 is separated with two dumbbell heads 1, two buckle 4
Bottom is connected in respectively in the corresponding card slot 3 of two dumbbell head 1, realizes the transformation of dumb-bell shape attitude.
The connecting rod 2 is made of the body of rod that two axial threads connect together.
As shown in figure 3, the upper end and 5 screw thread of threaded block for buckling 4 connect by being welded with threaded block 5 inside connecting rod 2
It connects.Buckle 4 may be implemented by rotary buckle 4 to be hidden in inside connecting rod or buckle 4 is extended connecting rod 2.
The working principle of the invention: there are two types of usage modes by the present invention, as shown in Figure 1, the both ends of connecting rod 2 are connected to
It is the dumbbell form under normal condition when between two dumbbell heads 1；
As shown in Fig. 2, the buckle 4 at 2 both ends of connecting rod is screwed out into connecting rod 2 when connecting rod 2 being needed to be located at two 1 tops of dumbbell head,
Two buckles 4 are inserted into respectively in the card slot 3 on two dumbbell heads 1.
The preferred embodiment of the patent is described in detail above, but this patent is not limited to above-mentioned embodiment party
Formula within the knowledge of one of ordinary skill in the art can also be under the premise of not departing from this patent objective
It makes a variety of changes.
