Background technique
Fitness equipment of the chest expander as current mainstream, it is very popular, it uses simply, it is easy to carry, be all
The optimal selection of the daily body-building of people, but in the prior art, chest expander mainly using spring as pulling force core, steel strand exerciser
Big ting model mainly depends on elastic size and quantity with spring, is difficult to accomplish the fine tuning of elastic size.Simultaneously in market
In, also at lacking a kind of steel strand exerciser used suitable for pupil or child.
In the prior art, it is used to cater to pupil or child, the means that steel strand exerciser is taken predominantly subtract
The strength that small single spring is drawn high, that is, pulling force；It is exactly to reduce number of springs.But no matter both methods is for bullet
Property fine tuning, and in the safeguard protection of pupil or child, all in certain hidden danger, therefore need to produce it is a kind of be applicable in
What pupil or child were applicable in, it easily adjusts, highly-safe chest expander.
Utility model content
The technical problems to be solved in the utility model is aiming at the shortcomings in the prior art, to provide a kind of adjustable drawing of air type
Power device.
The purpose of this utility model is achieved by the following technical programs:
A kind of air type adjustable drag device, including air pipeline, pull rod, pull ring；The air pipeline is hollow plastic tube；
The middle part of the air pipeline is equipped with interlayer, and left gas chamber, right gas chamber will be divided into inside hollow pipe；The air pipeline
Lateral surface adjusts screw there are two setting；The air pipeline both ends respectively connect a pull rod；Pull ring is respectively provided on the pull rod.
Further, the air pipeline is straight-through for PVC；Be equipped in the middle part of PVC straight-through pipeline using glue it is fixed every
Layer.
Further, the lateral surface of the left gas chamber and right gas chamber is equipped with dismountable adjusting screw.
Further, the adjusting screw of the left gas chamber and right gas chamber is arranged at the 8-12mm of interlayer position.
Further, the pull rod is made of hollow pipe and push rod, and described hollow pipe one end is narrow meshed sealing end；It is described
The narrow meshed sealing end of hollow pipe is inserted into hollow pipe one end；The other end of the hollow pipe connects push rod；The push rod is for connecting
The one end for connecing hollow pipe is equipped with partition, and partition is bonded with hollow inside pipe wall, and can be moved left and right along hollow inside pipe wall.
Further, the hollow pipe passes through at the outlet contact of hot melt adhesive sealing and hollow pipe.
Further, the lateral wall of the left gas chamber and the hollow pipe of right gas chamber outer end, which marks, scale.
Compared with prior art, the utility model has the following beneficial effects:
A kind of air type adjustable drag device of the utility model, by using straight pipe inner air content number, make
At pressure change size, replace the spring pulling force of steel strand exerciser.On the pull rod for cooperating chest expander both ends in this way
Scale, the big minor adjustment for the pulling force that can be carried out to chest expander, the either pulling force of equimultiple adjust or the drawing of upper down scale
Power is adjusted.It is all based on pipeline configuration that the utility model is whole simultaneously, then is not in conventional springs chest expander, because not having
Steady chest expander is grabbed, steel strand exerciser is caused to be influenced pop-up by spring, injures held personnel or other people, it is effective to improve
The safety that pupil or child use.
Detailed description of the invention
Fig. 1 is a kind of internal structure chart of adjustable vacuum pull device.
Specific embodiment
The utility model is further described With reference to embodiment.Wherein, being given for example only property of attached drawing
Illustrate, expression is only schematic diagram, rather than pictorial diagram, should not be understood as the limitation to this patent；In order to which this reality is better described
With novel embodiment, the certain components of attached drawing have omission, zoom in or out, and do not represent the size of actual product；To ability
For field technique personnel, the omitting of some known structures and their instructions in the attached drawings are understandable.
Embodiment 1
As shown in Figure 1, a kind of air type adjustable drag device, including air pipeline 1, pull rod 5, pull ring 7；The air pipeline
1 is hollow plastic tube；The middle part of the air pipeline 1 is equipped with interlayer 9, and left gas chamber 2, the right side will be divided into inside hollow pipe 1
Gas chamber 3；The lateral surface of the air pipeline 1 adjusts screw 8 there are two setting；1 both ends of air pipeline respectively connect a pull rod 5；
Pull ring 7 is respectively provided on the pull rod 5.
In the present embodiment 1, above-mentioned air pipeline 1 selects PVC straight-through；It is equipped in the middle part of PVC straight-through pipeline and utilizes glue
Fixed interlayer 9, interlayer selects hardness high, and air-locked shaped plastics material, such as air-locked plastic lid, utilizes
Plastic lid is tightly secured in the straight-through middle part PVC by 502 glue.
As shown in Figure 1, the lateral surface of left gas chamber 2 and right gas chamber 3 is equipped with dismountable adjusting spiral shell in hollow pipe 1
Nail 8.The setting of the adjusting screw 8 of above-mentioned left gas chamber 2 and right gas chamber 3 is apart from the 8-12mm of interlayer position at, in the present embodiment 1, a left side
The adjusting screw 8 of gas chamber 2 and right gas chamber 3 is arranged at 9 position 10mm of interlayer.Above-mentioned dismountable adjusting screw is selected
Screw diameter is the adjusting screw of 3mm.
In the present embodiment 1, the pull rod 5 of air type adjustable drag device is made of transparent hollow pipe 51 and push rod 52, above-mentioned sky
51 one end of heart pipe is narrow meshed sealing end；Above-mentioned narrow meshed sealing end is inserted into 1 one end of hollow pipe, and hollow pipe 51 passes through hot melt
At the outlet contact of glue sealing and hollow pipe 1.The other end of hollow pipe 51 connects push rod 52；The push rod 52 is for connecting sky
One end of heart pipe 51 is equipped with partition, and partition is bonded with 51 inner wall of hollow pipe, and can be moved left and right along 51 inner wall of hollow pipe.Above-mentioned sky
Heart pipe 51 and push rod 52 form the structure of pull rod 5, and principle is approximately conventional syringe, and push rod 52 is equivalent to the piston of syringe
Core bar, hollow pipe 51 are equivalent to the syringe of syringe, and piston core pin can move inside syringe.Above-mentioned left gas chamber 2 and right gas
The lateral wall of the hollow pipe 51 of 3 outer end of room, which marks, scale.
A kind of air type adjustable drag device of the utility model, installation process: interlayer 9 is adhesively fixed by glue
1 middle part of hollow pipe, and at away from 9 left and right sides 10mm of interlayer, the aperture of each one diameter 3mm of electric drill is adjusted for being arranged
Screw 8.In the both ends connecting rod 5 of hollow pipe 1, and the contact mouth of hot melt adhesive sealed hollow tube 51 and hollow pipe 1 is used,
Glue is injected into suitable glue from the aperture of installation and adjustment screw 8 simultaneously, then downward by pull rod, hollow pipe is put in upper
It sets mode, places a period of time, after waiting for a period of time, glue can further will be in 52 outer wall of hollow pipe and hollow pipe 1
