It connects.15 outer sheaths of blocking are equipped with shield 12, and it is tubular that shield 12, which is flexible material, and both ends have opening, pass through protection
Cover 12 enables block 15 not fall off from 11 side of column.
Hollow structure is set by column 11, and ratchet 29 and runner 13 are set at the top of it, making can inside column 11
Tennis is stored, and quickly can take ball inside column 11 when in use, column 11 is made to can be used as the use of tennis memory,
People are facilitated to carry out tennis in regular tennis court.
Column 11 has inner cylinder 19 and outer cylinder 20, and interlayer 22 is formed between inner cylinder 19 and outer cylinder 20, convenient in interlayer 22
The components such as limit film 27 and bracing wire 26 are set.It is accommodating chamber 21 inside inner cylinder 19, the diameter of accommodating chamber 21 is 7-7.5cm, bigger
In the diameter of tennis（6.5-6.8cm）, make that multiple tennises can vertically be arranged in accommodating chamber 21, and tennis will not be clamped on appearance
It receives in chamber 21.
There is supporting table 23, multiple tennises are placed on the top of supporting table 23 in inner cylinder 19.The side of supporting table 23 is arranged
Bracing wire 26 is arranged on convex block 24, can pull up supporting table 23 by bracing wire 26, enable tennis one by one for convex block 24
It is removed.Three convex blocks 24 are arranged in the side of supporting table 23 altogether, and three convex blocks 24 are uniformly arranged, and are being pulled upwardly supporting table 23
Uniform force when dynamic, can smoothly move up.
Wears groove 25 is set on inner cylinder 19, convex block 24 is enable to pass through wears groove 25 and is protruded into interlayer 22.The top of interlayer 22
With limit film 27, limit film 27 is circular ring shape, and the outer ledge of limit film 27 is connected to the inside edge of inner cylinder 19.Limit film
There are three limit holes 28 for setting on 27, and a bracing wire 26 passes through a limit hole 28 to be made to limit by the position-limiting action of limit hole 28
The bracing wire 26 below of bit slice 27 is at vertical state, and after being pulled bracing wire 26, convex block 24 can smoothly rise.
It is provided with ratchet 29 on the outside of the top of outer cylinder 20, is completely embedded between ratchet 29 and outer cylinder 20, makes ratchet 29 not
It can rotate.Runner 13 is connected at the top of ratchet 29, runner 13 and ratchet 29 are rotatablely connected, are provided with pawl 35 on runner 13, make
29 mechanism of ratchet is formed between runner 13 and ratchet 29.
The edge of runner 13 has extension 34, and pawl 35 is arranged in the inside of extension 34, and the end of pawl 35 is connected to
In the tooth socket 30 in 29 outside of ratchet, in the case where pawl 35 is not by other power, runner 13 can be rotated, and be merely able to towards one
Direction rotation.The top of bracing wire 26 is connected to the bottom surface of runner 13, runner 13 is made to be able to drive the movement of bracing wire 26 when rotating, into
And supporting table 23 is driven to rise.
When in use, supporting table 23 is first in lowest position, tennis is put into one by one in accommodating chamber 21.Take ball
When, rotating wheel 13, runner 13 drive bracing wire 26 move upwards, bracing wire 26 pulls up supporting table 23, enable tennis by
On lift, so that tennis is taken out.It is this to take ball mode, user is easily taken out of column 11 when playing ball
Ball number, lifting motion experience are picked up in ball, reduction.
After the tennis in column 11 is all removed, pawl 35 is stirred, divides pawl 35 and the tooth socket 30 of ratchet 29
From, so that runner 13 is rotated backward, supporting table 23 is enable to drop to the lowermost end of accommodating chamber 21, it at this time can be by tennis again
It is put into accommodating chamber 21, can so be recycled.
Ratchet 29 is circular ring shape, is set in the top of outer cylinder 20.The bottom of ratchet 29 has clamping ring 31, clamping ring 31
It is also circular ring shape.Connecting hole 32 is set on clamping ring 31, jackscrew 33 is set in connecting hole 32, it can be by clamping ring by jackscrew 33
31 and ratchet 29 be close-coupled at the top of outer cylinder 20, remain stationary ratchet 29.
It, can after being pulled upwardly the back guy 26 of rotating wheel 13 in the wire casing 36 of the bottom of runner 13 setting annular
It is stored temporarily in wire casing 36, makes the bracing wire 26 between limit film 27 and runner 13 will not be in disorder, bracing wire when inverting runner 13
26 can be pulled down, and supporting table 23 is enable to decline.
The end of pawl 35 and the inside of extension 34 are hinged, keep pawl 35 movable, the middle part of pawl 35 is provided with
Tension spring 37 be stuck in pawl 35 can steadily in card slot 38 under the pulling force effect of tension spring 37.
Card 39 is set in the outside of runner 13, enables and controls pawl 35 in the outside of runner 13, enable pawl 35
It is enough easily to be separated with card slot 38, so that runner 13 can rotate backward, enable 23 rapid decrease of supporting table.
Extension 34 has certain thickness, and card slot 38 is arranged in the outside of extension 34, and card slot 38 is longer, sets in card slot 38
Card 39 is set, card 39 is arc, is adapted to the lateral profile of extension 34.Card 39 is arranged in card slot 38, is not easy to fall,
And connected between card 39 and card slot 38 more closely, so that card 39 is not lived in card slot 38 in the case where not being struck
It is dynamic.It is connected between card 39 and pawl 35 by control line 41, the position of pawl 35 is controlled when enabling to stir card 39.Card slot
38 are connected to wider one end of card 39 with the T-shaped structure of card 39, control line 41.
Under normal circumstances, the control line 41 positioned at 34 inside of extension more relaxes, and makes pawl 35 will not be by control line
41 are controlled, and pawl 35 is enable to move freely inside extension 34.When stirring card 39, control line 41 can be tensed, and
Pawl 35 is pulled, so that pawl 35 is fitted in the inner wall of extension 34, pawl 35 is enable to separate with tooth socket 30.At this point,
Supporting table 23 by gravity effect falls downward, pull bracing wire 26, rotate backward runner 13, enable supporting table 23 restore to
Home position.
Pawl 35 shown in the accompanying drawings is arc, and tooth socket 30 is skewed slot, and control line 41 and tension spring 37 are located at pawl 35
Two sides.In practical solution, the not necessarily this shape of pawl 35, tooth socket 30 also not necessarily in this way design, control line 41 with
Tension spring 37 can also be in the same side of pawl 35.
Strip 42 is provided at the top of ratchet 29, strip 42 is arc-shaped, and multiple strips 42 are located on same circumference；Strip 42
Section is arc, has certain restraint after so that strip 42 is caught in the sliding slot 43 of 13 bottom of runner, make runner 13 be not easy with
Ratchet 29 is detached from.Strip 42 is caught in after sliding slot 43, so that runner 13 is connected to the top of ratchet 29 relatively stablely, and make
Obtaining runner 13 can rotate, and when needing to remove runner 13, firmly upwards can lift runner 13.
Runner 13 is set as cirque structure, and the tennis inside column 11 is enable to be removed.The intermediate connection of runner 13
There is cover board 45, cover board 45 is spirally connected with runner 13, keeps the two connection relatively stable；The middle part of cover board 45, which is provided with, turns round item 46, passes through
Turn round item 46 can easily rotating plate 45, be detached from cover board 45 and runner 13.When not in use, cover board 45 is connected to runner
13 middle part can prevent the tennis stored in accommodating chamber 21 from falling.
As it can be seen that the tennis barrel structure design of this structure is rationally, it can be used as tennis net, can also be used as storage net
The container of ball uses, and user can select according to the demand of itself.And its is compact-sized, is easy storage and carries.
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
It is not intended to be limited to the embodiments shown herein, and is to fit to and the principles and novel features disclosed herein phase one
The widest scope of cause.
