A kind of telescopic satellite reception ancient cooking vessel
Technical field
The present invention relates to satellite earth antenna, specially a kind of telescopic satellite reception ancient cooking vessel.
Background technology
Of high cost, the transport inconvenience of satellite heavy caliber satellite earth antenna.
Invention content
The technical problem to be solved in the present invention is to provide a kind of telescopic satellite reception ancient cooking vessel, extensible or contraction.
The present invention is realized in above-mentioned technical problem:
A kind of telescopic satellite reception ancient cooking vessel, including a pedestal, several pieces blades, several sliding slots, it is characterized in that, the chassis
Outer surrounding protrudes several sliding slots, and the blade is inserted into installation on the chute.
Described one spacing head of sliding slot entry design, avoids blade from running out of.
The blade is topmost rolled into a semicircular cylinder, and semicircular cylinder prevents leaf abscission.
It after the blade is fully mounted at pedestal, is overlapped mutually between blade and blade or so, on semicircular cylinder and semicircular cylinder
Lower overlapping, when pulling any one blade, all blades are and then stretched out or are shunk.
A protrusion is protruded in the lower section of the blade, for preventing vane extension transition from running out of, the protrusion and limiting capitiform
Into an integrated positioning.
Any one blade is pushed down on, which drives rest blade to shrink downwardly together, until blade full retraction arrives
The outer downside on chassis, at this point, convenience in transport and storage;Any one blade is pulled up, which drives rest blade to stretch upwards
Exhibition, it is in the form of annular discs.
Further, the back side of any one blade is equipped with a knob, for human hand pulling or push blade, just
In the stretching or contraction of blade.The knob is draw ring, the internal diameter 2cm of the draw ring or so.
The shape of the reception ancient cooking vessel of the discoid and satellite earth antenna is similar.
The present invention is used to substitute the reception ancient cooking vessel of existing satellite earth antenna.
Description of the drawings
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
The blade that Fig. 1 is the present invention stretches out schematic diagram.
Fig. 2 is the vanes retract schematic diagram of the present invention.
Fig. 3 is the blade figure of the present invention.
Fig. 4 is the blade side figure of the present invention.
Attached drawing identifier declaration:
1. pedestal, 2. blades, 3, semicircular cylinder, 4. protrusions.
Specific embodiment
It please refers to Fig.1 shown in ~ 4, the embodiment of the present invention is described in detail.
In Fig. 1,2, the present invention relates to a kind of telescopic satellite reception ancient cooking vessel, the retracted antenna include a pedestal 1, several pieces
Blade 2, several sliding slots, the outer surrounding of the pedestal 1 protrude several sliding slots, and the blade 2 is inserted into installation on the chute.
In fig. 2, it after the blade 2 is fully mounted at pedestal 1, is overlapped mutually between blade 2 and blade 2 or so, semicircle
Cylinder 3 is overlapped with semicircular cylinder about 3, and when pulling arbitrary a piece of blade 2, all blades 2 are and then stretched out or shunk.
In figure 3, described 2 the top of blade is rolled into a semicircular cylinder 3, and semicircular cylinder 3 prevents blade 2 from coming off.
In Fig. 4, a protrusion 4 is protruded in the lower section of the blade 2, is run out of for preventing blade 2 from stretching transition, the protrusion
4 form an integrated positioning with spacing head.
