In the shaft of frame, driving moment is provided for the expansion of hinge；One end of second torsionspring is fixedly mounted on it
In the shaft of itself, the other end, which is fixedly mounted on, to be adjusted on ratchet, and the second torsionspring provides for hinge expansion
Torque is buffered, the initial torque of the second torsionspring of ratchet adjustable is adjusted；Driving gear is fixedly connected on expansion
On holder；Driven gear engages to form speed-raising wheel system with driving gear；Being dug on the driven gear has idle running
Groove, driven gear empty set is in the shaft of the second torsionspring；When driven gear rotates, it is mounted on second
Spacer pin in torsionspring shaft drives the second torsionspring shaft one by the idle running groove on driven gear
Rotation is played, and the second torsionspring is driven to reverse simultaneously；Lock link and expansion holder are respectively mounted on the shell；
The both sides of shell are installed with cover board, and the first torsionspring, the second torsionspring adjust ratchet, linkage
The shaft of wheel is fixedly mounted on the cover board of shell both sides；It is dug in the expansion holder and is useful for locking
Groove；After expansion holder expands in place, lock link is caught in the groove on expansion holder；When expansion branch
Frame collapse when, be mounted on expansion holder on arc push rod push coupled wheel one end rotation, coupled wheel it is another
One end compresses external expansion object, when holder expansion is unfolded, completes the release to external expansion object.
The advantages of the present invention over the prior art are that：
(1) driven gear and the design of the second torsionspring axis empty set and driven gear and the second torsionspring are used
Transmission idle running design between axis, realizing hinge, half way only has driving spring work, hinge to exist in the pre-deployed
First half term only provides power.
(2) it uses the increasing transmission design between driven gear and driving gear and sky is being driven by spacer pin
Journey end drives the design that the second torsionspring axis rotates together, and realizes and the second half low-angle is unfolded in hinge
Pooling feature in range.
(3) using by the frame of expansion arc push rod promotion coupled wheel rotate by a certain angle, coupled wheel it is another
One end compresses the design of the second expansion module, realizes the linkage pressure of first the second expansion module of expansion module pair
Tight and release.
Description of the drawings
Fig. 1 is that the present invention applies the schematic diagram on certain antenna armful loop device；
Fig. 2 is side sectional view of the present invention；
Fig. 3 is front section view of the present invention.
Specific implementation mode
Below in conjunction with the accompanying drawings and realization process of the invention is discussed in detail in specific example.
As shown in Figure 1, connection embraces ring by the first expansion module 13, the second expansion module 14, third expansion group
Part 15, the present invention expansion compositions such as hinge and blasting bolt；When rounding state, the unlock for embracing ring is to pass through
What blasting bolt was completed, the expansion hinge that spreads across of each expansion module is completed.
It is turned round by shell 1, expansion holder 2, first as shown in Fig. 2, net-shape antenna of the present invention embraces ring expansion hinge
Turn spring 3, driving gear 4, driven gear 5, the second torsionspring 6, adjust ratchet 7, coupled wheel 8
And lock link 9, spacer pin 10, arc push rod 11 and cover board 12 form.First torsionspring 3
For providing driving moment for the expansion of hinge, it is installed in the shaft of expansion holder 2；Second torsionspring 6
End stage is unfolded for hinge, buffering torque is provided, an end of spring is fixed on the second torsionspring 6
In shaft, the other end, which is fixed on, to be adjusted on ratchet 7；Driving gear 4 is connected by screw in expansion holder 2
On；Driven gear 5 engages the raising speed train for forming 3: 1 transmission ratios with driving gear 4；The driven tooth
The idle running groove for there are 270 ° is dug on wheel 5,5 empty set of driven gear is in the shaft of the second torsionspring 6；Exhibition
When frame 2 of paying wages is unfolded, driving gear 4 drives driven gear 5 to rotate, when driving gear 4 rotates 90 °,
