Wherein, four legs 11 of the vehicle frame 10 including the arrangement that is square form four sides, are set between adjacent two leg 11
There is arm support 12 to be located in each side.Each arm support 12 includes two and is pivotally connected in the strut 121 intersected at middle part.Each strut
121 upper end and the upper end of the strut of adjacent side are articulated on a upper connector 13 being arranged at the top of leg at the same time, upper company
Fitting 13 extends to form pivot joint auricle 131 to connect the upper end of strut 121 to two side surface directions.And under each strut 121
End and the lower end of the strut 121 of adjacent side are articulated on a lower connector 14 being movably connected on leg 11 at the same time, lower company
Fitting 14 is located at the lower section of upper connector 13, is positioned after being slided up and down in strut.Lower connector 14 prolongs to two side surface directions
Stretch to form pivot joint auricle 141 to connect the lower end of strut 121.The both ends of the strut 121 intersected in each side are connected to
On upper connector 13 and lower connector 14, the both ends of the strut 121 of the intersection of adjacent side are respectively connected to positioned at leg 11
On upper connector 13 and lower connector 14.When need by each leg 11 receive by when, two struts 12 in arm support 12 are inside
Closing, drives the activity downwards on leg 11 of lower connector 14, is close together until adjacent leg 11 is received.Conversely,
When needing vehicle frame 10 being unfolded, receipts are leaned against into arm support expansion, drive two legs 11 to open.At the bottom of each leg 11
End is also associated with a universal wheel 15 for carrying locking device, easy to use so as to make tennis car slidably and position.
As shown in Figure 1 and Figure 2, can be socketed a ball bag 2 on vehicle frame 10, the expansion of bag body 21 of ball bag 2 formed it is square basket,
Bag 21 four corners of body, which are respectively equipped with one, can be set in the lantern ring 22 or bandage of 11 upper end of leg, and the lantern ring 22 can be set in upper connector
On 13, so as to coordinate four inner sides of leg 11, expansion bag body is formed after 11 upper end of leg is set in when each leg 11 is unfolded,
Tennis can be placed into bag body 21.One retractable upper cover 23 can be set above bag body, and upper cover 23 can pass through the form of slide fastener
It is arranged on bag body 21 in plane, so as to cover ball bag, avoids the tennis in ball bag from dropping in the handling process.On bag body 21
Hand-strap 24 or shoulder belt can be also set, facilitate ball bag to take out and carry.
To avoid the ball bag being socketed between leg from sinking because of weight issue in middle part stress, making for ball bag is influenced
With, in the utility model, it is additionally provided with a midfoot support frame between each leg 11, and midfoot support frame 4 and each arm support 12
Interlock, be unfolded with the folding expansion folding at the same time of arm support 12.Midfoot support frame 4 includes four supporting rods 41 and is pivotally connected at middle part
On a middle part connecting seat 42, the outer end of supporting rod 41 is pivoted on the lower connector 14 in each leg 11, supporting rod 41 it is interior
End is pivoted in the connecting seat 42 of middle part, and middle part connecting seat 42 is on the axial line for the square column that four legs 11 are formed, at middle part
The four formed below pivot connected slots 421 to radially distribute of connecting seat 42 connect to connection support bar 41, each supporting rod 41
Can downward folding in middle part connecting seat 42.When each leg 11 collapses, each supporting rod 41 is movable downwards and inwardly receipts are leaned on, middle part
Connector 42 arches up, and lower connector 14 moves down, and each supporting rod 41 is with the receipts of each leg 11 by also concentrating receipts to lean on.Conversely, each leg
During expansion, middle part connecting seat 42 pushes, and lower connector 14 moves down naturally.
Further, it can also be covered on vehicle frame 10 and connect an object-putting layer 3, a pipe is equipped with end position on the lower in each leg 11
Set 16, is socketed a glove between each pipe sleeve 16, and 3, during the expansion shape correspondence of object-putting layer 3 is on the inside of four legs of expansion, glove
Layer can be screen cloth, pocket or support chip etc., and the connector 31 that can be fixed on above casing 16 is equipped with the four corners of object-putting layer 3,
Connector 31 can be bandage or the tool opening lantern ring.Connector 31 by casing block, make object-putting layer 3 be supported in four legs it
Between, so as to place racket or other debris on object-putting layer 3.
Coordinate shown in Fig. 1, Fig. 3, Fig. 4, when needing to use vehicle frame, when vehicle frame 10 is unfolded, each leg 11 is with arm support
During 12 expansion, flared each leg 11 drives supporting rod 41 to be unfolded at the same time, so that the expansion of midfoot support frame 4 is supported on leg
Between 11, when set receives bag 2, ball bag is between each leg 11 at the same time positioned at the top of midfoot support frame 4, midfoot support frame 4
It is supported on below ball bag, support is formed in the bottom surface of ball bag, when being put into tennis in ball bag 2, ball bag can be avoided to be concentrated because of middle part
Stress and sink.Furthermore it can be covered above each pipe sleeve 16 and connect object-putting layer 3, object-putting layer 3 is supported between each leg 11, can be made
Used to put layer.Conversely, when tennis car is accepted, individually first ball bag 2 and object-putting layer 2 can be packed up from vehicle frame 10,
Arm support 12 between each leg 11 is inwardly collapsed into closing, lower 14 slide downward of connector, makes each in midfoot support frame 4
Supporting rod 41 is movable downwards and inwardly receipts are leaned on, and 42 upward lifting of middle part connector, lower connector 14 moves down, each supporting rod 41
It is close together with the receipts of each leg 11 by also being received at middle part, last folding is small size, state as shown in Figure 4.
The portable tennis car of the utility model, when use, each leg was unfolded, simultaneous linkage by midfoot support frame in the lump
Expansion, then ball bag and object-putting layer are supported in vehicle frame and used, each leg is inwardly received lean on when not in use, while also drive middle part
Supporting rack is received at middle part and leaned on, you can assembling is folded into small size.The utility model integrally can be achieved one and interlock exhibition receipts, structure letter
Single, easy to operate, when expansion, can enable ball bag is more firm to mount on vehicle frame, and can also form object-putting layer to place racket,
Using more portable.
