The utility model discloses except having the function of taking exercises, can regard as quantitative determination student's arm pulling force simultaneously, in the practice teaching, can help the sports mr exact to measure an important indicator of student's fitness, while this chest expander novel structure, easy operation, the reading is convenient.
Description
Technical field
The utility model physical education field of exercise equipment is and in particular to a kind of student uses chest expander of imparting knowledge to students in groups.
Background technology
At present, the length by tension back pull spring that most of chest expanders on the market can only be quantitative estimates student
Arm tension size, so frequently can lead to that estimation is accurate, cause the irrationality that many teaching plans are implemented.With
When, many physical trainings, due to being limited by place apparatus, have many students that injured phenomenon, weight often occur in physical training
Person paralyses, and the lighter's soreness of waist and ache in legs brings a lot of inconveniences to learning life.
Utility model content
The purpose of this utility model is to provide a kind of student with chest expander of imparting knowledge to students in groups, to solve in above-mentioned background technology
The problem proposing.
For achieving the above object, the utility model provides following technical scheme：
A kind of student with chest expander of imparting knowledge to students in groups, including extension spring, the first chest expander handgrip and the second chest expander handgrip,
Described extension spring is fixed in connecting rod by retainer ring, and described retainer ring nut is fixed in connecting rod, and described chest expander is hung
Hook connects in described connecting rod, and described first chest expander handgrip and the second chest expander handgrip are separately fixed at described pulling force
On device hook, described extension spring middle setting has pulling force scale, and described pulling force scale passes through pull sensing line and described first pulling force
Device handgrip and the second chest expander handgrip are connected, and are connected to pointer in the middle of described pull sensing line, and described pointer is in semicircle
Shape, described pointer correspond to the reading on described pulling force scale.
As further program of the utility model：Five described extension springs are had, described retainer ring is in ellipse in described chest expander
Round shape, described retainer ring is made using hot rolling steel wire.
As further program of the utility model：Described pull sensing line adopts mild steel wire.
As further program of the utility model：20N, 30N, 40N is indicated in described pulling force scale.
As further program of the utility model：The last total of described chest expander pulling force scale is in five described extension springs
The pulling force being subject to is separately summed, and described first chest expander handgrip and the second chest expander handgrip adopt elastomeric material, are simultaneously provided with
Antiskid thread.
Compared with prior art, the utility model, except having the function of taking exercises, is learned at the same time as quantitative determination
Raw arm tension, in practical teaching, can help P.E. teacher correctly to weigh an important indicator of Students Physical；With
When this chest expander structure novel, simple to operate, convenient reading.
Brief description
Fig. 1 is a kind of structural representation with chest expander of imparting knowledge to students in groups for student.
In figure：1- chest expander hook, 2- extension spring, 3- retainer ring, 4- connecting rod, 5- the first chest expander handgrip, 6- second
Chest expander handgrip, 7- pulling force sensor, 8- pointer, 9- pulling force scale, 10- pull sensing line.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of student with chest expander of imparting knowledge to students in groups, including extension spring 2, first
Chest expander handgrip 5 and the second chest expander handgrip 6, described extension spring 2 is fixed in connecting rod 4 by retainer ring 3, described fixation
Ring 3 nut is fixed in connecting rod 4, and described chest expander hook 1 is connected in described connecting rod 4, and described first chest expander is held
Hand device 5 and the second chest expander handgrip 6 are separately fixed on described chest expander hook 1, and described extension spring 2 middle setting has pulling force to carve
Degree 9, described pulling force scale 9 passes through pull sensing line 10 and described first chest expander handgrip 5 and the second chest expander handgrip 6 phase
Connect, in the middle of described pull sensing line 10, be connected to pointer 8, described pointer 8 semicircular in shape shape, described pointer 8 correspond to described
Reading on pulling force scale 9.
Except having the function of taking exercises, at the same time as quantitative determination student's arm tension, in practical teaching, can
P.E. teacher is helped correctly to weigh an important indicator of Students Physical；This chest expander structure is novel simultaneously, operation letter
Single, convenient reading.By arranging pull sensing line, after using Newton's law, draw the reading on pulling force graduation apparatus, then pass through
Pointer reflects, and can accurately record required physique constitution of students status data.Adopt elastomeric material simultaneously and anti-skidding spiral shell is set
Line, increases the frictional force between hand and chest expander handgrip.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, this practicality can be realized in other specific forms new

All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limiting
Involved claim.
Moreover, it will be appreciated that although this specification is been described by according to embodiment, not each embodiment only wraps
Containing an independent technical scheme, only for clarity, those skilled in the art should for this narrating mode of specification
Using specification as an entirety, the technical scheme in each embodiment can also form those skilled in the art through appropriately combined
Understandable other embodiment.
