Outside, cylinder 11 is made of metal, when block 18 is wrapped in the outside of cylinder 11, by the suction of magnetic patch 23, makes block 18
It can be steadily wrapped in the outside of cylinder 11, it is not easily to fall off.The protective effect of mating sleeve 12 again enables block 18 more
Stablize.
Hollow structure is set by cylinder 11, makes that tennis can be accommodated inside it.And pedal 13 is set on cylinder 11, is passed
The dynamic components such as chain 28 and lifting platform 26, enable the tennis contained in cylinder 11 to be easily removed, the energy when carrying out tennis
It is enough that convenience is provided.
It is cylindrical cavity inside cylinder 11, top has opening, enables its internal tennis loaded from its top
It takes out.When formal tennis court carries out tennis, Tennis net frame can be used as the container for loading tennis, provide net to user
Ball, to reduce the number for picking up tennis.
The top of sleeve 12 has cover board 25, and cover board 25 and sleeve 12 are detachably connected, block 18 being not used and
It needs cylinder 11 as tennis container to be arranged sleeve 12 still can in use, the cover board 25 at 12 top of sleeve is opened
Block 18 is protected in the outside of cylinder 11, and the tennis inside cylinder 11 is enable to take out from top.
It is provided with lifting platform 26 in accommodating chamber 24, there is circular groove 46 in the middle part of lifting platform 26, facilitate and be placed on tennis above.
Lifting platform 26 can be gone up and down inside accommodating chamber 24, and the tennis in accommodating chamber 24 is enable to be removed.The two sides of lifting platform 26 are set
It is equipped with lug 45, slide opening 29 and straight-tooth 30 are respectively set on two lugs 45, lifting platform 26 is enable to connect slide bar 27 and transmission
Chain 28.Transmission chain 28 is engaged with the straight-tooth 30 that 26 side of lifting platform is arranged, and in 28 course of work of transmission chain, passes through the pass of engagement
Frenulum moves lifting platform 26 and moves upwards, and the connection relationship of slide bar 27 and slide opening 29 enables lifting platform 26 steadily to be risen
Drop movement, is not easy to be clamped in accommodating chamber 24.
Pedal 13, driving wheel 33 and the shaft 35 of 11 bottom of cylinder setting are matched with transmission chain 28, form transmission mechanism,
Transmission chain 28 is set to work by transmission mechanism.One end of pedal 13 is hinged on cylinder 11, can be rotated, 13 middle part of pedal
It is connect by return spring 31 with cylinder 11, reset pedal 13 can upwards automatically after stepping on.
The edge of pedal 13 is provided with pawl 32, and the side of pedal 13 is arranged in driving wheel 33, and the axis of driving wheel 33 is
Horizontal direction, the side of driving wheel 33 are provided with multiple tooth sockets 34, and the end of pawl 32 can be caught in tooth socket 34.It is stepped on stepping on
When plate 13, pawl 32 is able to drive the rotation of driving wheel 33.After unclamping pedal 13, pedal 13 resets, and pawl 32 is detached from
Tooth socket 34, behind the recovery of pedal 13 to extreme higher position, pawl 32 is caught in again in tooth socket 34, and driving wheel 33 is protected in this process
It holds motionless.Form ratchet mechanism.
Driving wheel 33 is connected with shaft 35, and shaft 35 is rotationally connected on cylinder 11, and driving wheel 33 being capable of band when rotating
Turn axis 35 rotates.It is provided at the top of cylinder 11 from axis 36, is connected on cylinder 11 from the both ends of axis 36, will not turned from axis 36
It is dynamic.Transmission chain 28 is set in shaft 35 with outside axis 36, after shaft 35 rotates, is able to drive the rotation of transmission chain 28.Turn
It is also possible to make to skid therebetween, enable the rotation of shaft 35 by tooth engagement between axis 35 and transmission chain 28
Steadily transmission chain 28 is driven to rotate.
This transmission mechanism when in use, steps on pedal 13, and pedal 13 drives driving wheel 33 to rotate, and driving wheel 33 is with turn
Axis 35 rotates, and shaft 35 drives transmission chain 28 to rotate, and transmission chain 28 drives lifting platform 26 to move upwards, and makes to place on lifting platform 26
Tennis can be jacked up upwards, so that tennis is taken out one by one.
In use, user can stand cylinder 11 aside, when needing with ball, it is primary or more to step on pedal 13
It is secondary, eject lifting platform 26 by a tennis.
After whole tennises in accommodating chamber 24 are removed, pawl 32 is adjusted, pawl 32 is separated with tooth socket 34, makes spine
Pawl 32 and pedal 13 will not cause to hinder to rotating backward for driving wheel 33, so that driving wheel 33 is rotated backward, make transmission chain
28 can rotate backward, and lifting platform 26 is enable to drop to extreme lower position, can get the ball on court back come at this time, and put into
In cylinder 11, reuse.
Adjusting rod 37 is set in 11 bottom of cylinder, quickly pawl 32 and tooth socket 34 can be detached from by adjusting rod 37, made
26 rapid decrease of lifting platform.
The end of adjusting rod 37 and cylinder 11 are hinged, tension spring 38 are provided between middle part and cylinder 11, in normal state
Under, adjusting rod 37 is in higher position, and is located at the surface of pawl 32, between pedal 13 and driving wheel 33.It needs
When using adjusting rod 37, adjusting rod 37 is stirred downwards, is bonded adjusting rod 37 with pawl 32, and pawl 32 can be made to be detached from tooth socket
34.After use, adjusting rod 37 is unclamped, adjusting rod 37 can set back under the action of tension spring 38.Pawl 32 also can
It enough sets back, is caught in tooth socket 34.
Pawl 32 is common component.In the present embodiment, the arc-shaped structure of pawl 32, one end are hinged on pedal 13
Bottom is connected with spring between the middle part and pedal 13 of pawl 32.When pedal 13 moves downward, the end of pawl 32 is caught in tooth socket
In 34, and driving wheel 33 is driven to rotate.
11 bottom of cylinder has housing, and housing is connected on cylinder 11, and groove 39 is formed in housing, makes pedal 13 and adjusts
Bar 37 can be arranged in groove 39, and housing is enable to play a protective role each component.But also the size of cylinder 11 can
What is made is smaller, and the bottom of cylinder 11 is enable to have bigger fitting area with ground, keeps cylinder 11 more stable.
To rotate backward the back pedal 13 for unclamping pedal 13 driving wheel 33 during setting back will not, in shaft
35 end is provided with damping block 40.It is the relationship being bonded between damping block 40 and shaft 35, and damping block 40 is to shaft 35
Rotation has certain damping.The back pedal 13 for unclamping pedal 13 is very short in the whole process time-consuming of upward homing, probably
Several seconds time of zero point, within this time, damping block 40 enables shaft 35 to be tentatively held in the active force of shaft 35
The state, it is ensured that shaft 35 will not invert.
As can be seen that the Tennis net frame of this structure is vdiverse in function, it can be used as tennis net and come using can also be used as splendid attire
The container of tennis comes using user can select its function according to the actual situation, bring biggish convenience to user.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, of the invention
