Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
Shown in referring to Fig.1, an embodiment of the Portable map-hanging frame of the utility model, including a pair of of pedestal 100, a pair of of cross
Bar 210 and a pair of of vertical bar 220,220 grafting of one pair of them vertical bar are installed on the pair of pedestal 100, and a pair of of cross bar 210 is removable
It is connected to unloading on the pair of cross bar 210, forms frame structure.
Specifically, referring to fig. 2, the pedestal 100 includes bottom plate 110 and the positioning convex platform formed by 110 projection of bottom plate,
The jack 121 for grafting vertical bar 220 is offered on positioning convex platform.In order to increase the stability of pedestal 100, the bottom plate 110
Preferably strip, the waist type including but not limited in the present embodiment.In order to reduce the weight of positioning seat, preferably convex
Platform is that cross section is trapezoidal positioning plate 120, and deep floor 122 is fixedly connected between bottom plate 110 and positioning plate 120.At it
In his embodiment, positioning plate 120 can be other shapes, such as rectangle.
In the utility model, the cross bar 210 and vertical bar 220 pass through locking part 300 by least two hollow bars 230
It connects and is formed two-by-two.
Fig. 4-6 is referred to, the locking part 300 includes attachment base 310 and expansion sleeve 320, wherein the attachment base 310
One end can closely plug together in a strut 230, so that the rotation of strut 230 is able to drive the rotation of attachment base 310.Attachment base
310 other end is the cylinder that radius is gradually increased, and has on the cylinder and offers annular groove 311.In the present embodiment, the ring
Slot 311 is two.In other embodiments, the number of annular groove 311 includes but is not limited to two.The expansion sleeve 320 be with
The non-closed expansion sleeve 320 of elasticity, is sleeved on the attachment base 310, and its inner wall has and the annular groove 311 cooperation
, the ring rib 321 that degree of convexity is gradually increased.Another strut 230 is sleeved on expansion sleeve 320.Preferably, cylinder
Two sides are equipped with retaining ring 312 to limit to expansion sleeve 320.
When with scheduled direction, such as clockwise, when relatively rotating the strut 230 of 310 two sides of attachment base, drive described swollen
Expansion set 320 and attachment base 310 relatively rotate, and the raised line 321 of the expansion sleeve 320 is rotated along annular groove 311 at this time, due to annular groove
311 radius gradually increases, therefore raised line 321 can gradually be made expansion sleeve 320 expand by the extruding of annular groove 311, in turn
Expansion sleeve 320 squeezes the inner wall of corresponding strut 230 again, to realize the locking between strut 230 and attachment base 310.
When relatively rotating the strut 230 of 310 two sides of attachment base in a reverse direction, sliding of the raised line 321 along annular groove 311
In the process, the radius of annular groove 311 is gradually reduced, and the extruding force that raised line 321 is subject to is gradually reduced, and expansion sleeve 320 is in elastic recovery
It shrinks, therefore strut 230 and is unlocked between attachment base 310 under the action of power.
Occurs opposite sliding between strut 230 and expansion sleeve 320 in order to prevent, preferably on the outer wall of expansion sleeve 320
It is uniformly distributed to have multiple convex blocks 322, to increase the frictional force between strut 230 and expansion sleeve 320.
In the present embodiment, the junction of two struts 230 is sheathed with protective case 500.
It referring to Fig. 3, is connected between cross bar 210 and vertical bar 220 by dismountable connector, the connector includes first
Connector 410 and the second connector 420, wherein 210 need of underlying cross bar pass through the first connector 410 and vertical bar 220
Connection, and the cross bar 210 being located above is connect by the first connector 410 and the second connector 420 with cross bar 210.
Specifically, end has plugged together the first connector 410 for underlying cross bar 210, first connector
410 have the end face matched with 220 outer surface of vertical bar, and the first connector 410 has mutually matched spiral shell with vertical bar 220
Hole；The screw hole is passed through by lock-screw 430 to lock the first connector 410 and vertical bar 220, thus 210 He of fixed transverse rod
Vertical bar 220.
For the cross bar 210 being located above, end has plugged together the first connector 410, and the end of vertical bar 220 has plugged together
Second connector 420, first connector 410 have the end face matched with 420 outer surface of the second connector, and the first connection
First 410 and second connector 420 have mutually matched screw hole.The screw hole is passed through by lock-screw 430 to lock first
Connector 410 and the second connector 420, thus fixed transverse rod 210 and vertical bar 220.
In the present embodiment, also there is a bulb 421 on the second connector 420.
In other embodiments, when cross bar 210 is longer, the quantity of vertical bar 220 can be increased, with support rail 210.
The Portable map-hanging frame of the present embodiment, the lesser component composition such as You Duogen strut 230, pedestal 100, connector,
It is convenient for carrying.In assembling, multiple struts 230 are spliced to form to the cross bar 210 and vertical bar of random length by locking part 300
220, and the locking and unlocking of strut 230 can be realized by relatively rotating two struts 230, it disassembles and installs very convenient.
Embodiment described above is only preferred embodiments for fully illustrating the utility model, the utility model
Protection scope it is without being limited thereto.Those skilled in the art made equivalent substitute or change on the basis of the utility model
It changes, both is within the protection scope of the present invention.The protection scope of the utility model is subject to claims.
