Technical field
This utility model belongs to sports apparatus technical field, is related to a kind of basketball stands and in particular to a kind of adjustment height basket
Ball-collecting rack.
Background technology
In primary school, the classmate of senior class height compared with lower classmate is mutually far short of what is expected, but the basketball of school
Frame is often highly fixing, nonadjustable, often sets higher, is suitable for senior class classmate and uses, primary grades classmate throws
Basket is highly difficult, and up to the present also nobody solves such problem.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, adapts to reality need, provides a kind of adjustment height
Basketball stands.
This utility model is achieved through the following technical solutions：
A kind of height-adjustable basketball stand, including cage assembly, base assembly, air cylinder, one-way air inlet device, unload air valve and
Vent line, cage assembly includes backboard, basketry, guide rod and piston component, and piston component includes lifting piston rod and lifting is lived
Fill in, the back of guide rod upper end and backboard, that is, the one side relative with basketry is fixedly connected, the back fixation of piston rod upper end and backboard
Connect；Base assembly includes base, guide pin bushing and lift cylinders, lift cylinders and piston component composition cylinder, the lower surface of lifting piston
The space fencing up with cylinder barrel and the bottom surface of lift cylinders is rodless cavity, and when charged pressure air in rodless cavity, piston component is just
Backboard can be driven to rise to certain height；Guide pin bushing is fixedly connected with base, and guide rod and guide pin bushing form moving sets, makes backboard along directly
Line lifts, and basketry can be made to keep steady statue；Air cylinder includes displacer assembly and cylinder body of calming the anger, displacer assembly bag
Include displacer rod and displacer, the space that the cylinder barrel of the lower surface of displacer and cylinder body of calming the anger surrounds is chamber of calming the anger；Single
Include ventilation lumen, inlet chamber and discharge chamber to air intake installation, also include air inlet bulb, air inlet stage clip, aerofluxuss bulb and exhaust pressure
Spring, ventilation lumen is connected with inlet chamber, discharge chamber and chamber of calming the anger respectively from three directions, and discharge chamber passes through vent line and no bar
Chamber is connected；Air inlet intracavity has air inlet taper hole, and towards outside air, big mouth, towards ventilation lumen, enters balloon to the osculum of air inlet taper hole
The sphere of head closely blocks air inlet taper hole, and air inlet stage clip one end compresses air inlet bulb, makes the sphere of air inlet bulb keep pressure
State that is tight and blocking air inlet taper hole, the other end compresses the inwall of inlet chamber；Aerofluxuss intracavity has an aerofluxuss taper hole, aerofluxuss taper hole little
Towards ventilation lumen, big mouth closely blocks aerofluxuss taper hole, aerofluxuss stage clip one end towards outside air, the sphere of aerofluxuss bulb to mouth
Compression aerofluxuss bulb, makes the sphere of aerofluxuss bulb keep the state of compression aerofluxuss taper hole, the other end compresses the inwall of discharge chamber.
When using, pull displacer rod repeatedly, displacer moves back and forth in air cylinder body, when compression is calmed the anger chamber
During interior air, the air of intracavity of calming the anger under pressure, can make air inlet bulb more closely block air inlet taper hole, can make
Aerofluxuss bulb overcomes the pressure of aerofluxuss stage clip to leave aerofluxuss taper hole, and the gap between aerofluxuss bulb and aerofluxuss taper hole is flow through,
Flow into rodless cavity eventually through vent line；
When displacer movement make to calm the anger the space in chamber increase when, the air pressure of intracavity of calming the anger declines until becoming negative
Pressure, the air pressure in rodless cavity is more than the air pressure of ventilation intracavity, and aerofluxuss bulb closely blocks aerofluxuss taper hole under differential pressure action,
Extraneous air pressure is more than the air pressure of ventilation intracavity, the air push air inlet bulb in the external world, and air inlet bulb overcomes the pressure of air inlet stage clip
Power moves, and the gap that outside air passes through between air inlet bulb and air inlet taper hole enters, by ventilation lumen, chamber of calming the anger；
Like this, pull displacer rod repeatedly, just constantly can transfer to extraneous air in rodless cavity.
Air exchange pipe is provided with and unloads air valve, unloads air valve one end and is connected with air exchange pipe, the other end leads to outside air, works as handle
When unloading air valve and being threaded to open, air in Gravitative Loads lower compression rodless cavity for the cage assembly passes through air exchange pipe and unloads air valve row
It is put into outside air, cage assembly declines, is down to and is suitable for the short students of the junior years' use of head, then rotary unloading air valve extremely cuts
Only state.
Although can be worked with handss pull displacer rod, that is very hard, in-convenience in use, in order to laborsaving and make
With convenient, the end of air cylinder, that is, there is no that one end that displacer rod is stretched, be connected with base by hinge two, calm the anger
The end of piston rod, that is, do not had that one end of displacer, be connected with lever by hinge one, and lever passes through hinge three and bottom
Seat is connected, and lever has long operation part, and when shifting lever reciprocal using handss, displacer rod is just with band action pneumatic
Piston moves back and forth in air cylinder body, and has reached purpose laborsaving, easy to use.
The beneficial effects of the utility model：Basketball stands height adjustable, the student being suitable for various heights uses, user
Just.

Bulb 73 overcomes the pressure of air inlet stage clip 74 to move, and the gap that outside air passes through between air inlet bulb 73 and air inlet taper hole 72 leads to
Cross ventilation lumen 71 and enter chamber 421 of calming the anger；
Like this, pull displacer rod 411 repeatedly, just constantly can transfer to extraneous air in rodless cavity 231.
Air exchange pipe 5 is provided with and unloads air valve 6, unloads air valve 6 one end and is connected with air exchange pipe 5, the other end leads to outside air,
When handle unloads air valve 6 and is threaded to open, air in Gravitative Loads lower compression rodless cavity 231 for the cage assembly 1 passes through air exchange pipe 5
It is discharged into outside air with unloading air valve 6, cage assembly 1 declines, be down to and be suitable for the short students of the junior years' use of head, Ran Houxuan
Unloading air valve is to cut-off state.
Although can be worked with handss pull displacer rod 411, that is very hard, in-convenience in use, in order to laborsaving
With easy to use, the end of air cylinder 4, that is, there is no that one end that displacer rod 411 is stretched, by hinge 2 82 and base
21 are connected, and the end of displacer rod 411 is not had that one end of displacer 412, be connected with lever 3 by hinge 1
Connect, lever 3 is connected with base by hinge 3 83, lever 3 has long operation part, when using the reciprocal shifting lever of handss 3
When, displacer rod 411 just with drive displacer 412 move back and forth in cylinder body 42 of calming the anger, and reached laborsaving, make
Use convenient purpose.
