Background technology
Shortwave whip antenna is in the past mounted on large ship, and the height of antenna does not exceed the height of mast, and antenna does not need folding to fall to operate.Afterwards due to expansion and the application in market, shortwave whip antenna was installed on various vehicle, and the gate sentry due to vehicle discrepancy limits the height of vehicle and institute's dress antenna, and antenna now needs folding to fall.Shortwave whip antenna can be regarded as a cantilever beam, and because antenna is very high, very heavy, and the environment installed has vibration, waves, the inertia force that antenna produces is very large, easily loosen after adopting general folding focusing device locking, be not easy locking, equipment is easily damaged.In order to address this problem, people generally adopt electric folding focusing device to lock, but the space adopting electric folding focusing device then to require to install is large, and device fabrication cost is high, and periodic maintenance is inconvenient, and inapplicable general vehicle uses, and use is very restricted.Therefore, must design one can manual operation, and simple to operate, and the special folding being not easy after locking to loosen falls locking device.
Summary of the invention
The purpose of this utility model is, falls the deficiency of locking device for existing folding, provides a kind of by supporting plate, the large-scale whip antenna entrucking folding focusing device of bottom support bracket and locking nut composition; This device adopts the method for cantilever beam structure one direction half-twist, providing counteracting antenna most gravity, being applicable to various vehicle uses by installing two torsionsprings in rotating shaft; And not easily loosen after locking, compact conformation, installation and maintenance are convenient, and time saving and energy saving, be conducive to the movement of environmental level, device fabrication expense is low, and manufacture craft is simple.
The utility model realizes above-mentioned purpose by the following technical solutions:
This large-scale whip antenna entrucking folding focusing device is made up of spindle housing, clamping bolt, location-plate, supporting plate, torsionspring and arc strut, it is characterized in that: the screw rod that passes on left of spindle housing is hinged with a supporting plate, torsionspring is equipped with at the middle part of screw rod, the front side of spindle housing is fixed with location-plate, location-plate is fixed with a minor axis; The front side of supporting plate is fixed with an arc strut by clamping bolt, and arc strut is manufactured with deep-slotted chip breaker, and deep-slotted chip breaker is sleeved on minor axis, and by being with the locking nut of Metallic rod to fix.
Described torsionspring is two, and one end of torsionspring is close to the left side of spindle housing, and the other end of torsionspring is close on supporting plate.
It is uniform in the heart in described supporting plate that to be manufactured with four diameters be the installing hole of 11mm.
Described spindle housing is fixedly mounted on car body mounting plane by four bolts.
The utility model beneficial effect is compared with prior art:
The folding that this large-scale whip antenna entrucking folding focusing device can realize locking when whip antenna is holded up and antenna falls function, is applicable to various vehicle uses, not easily loosens after locking; And compact conformation, install simple, easy to maintenance, time saving and energy saving, be conducive to the movement of environmental level, folding falls to erect efficiency high, and device fabrication expense is low, and manufacture craft is simple.Easily loosen after solving the locking of existing folding focusing device, be not easy locking, equipment is easily damaged; The space adopting electric folding focusing device then to require to install is large, cost is high, and inapplicable general vehicle uses, and the problem of periodic maintenance inconvenience.

Embodiment
This large-scale whip antenna entrucking folding focusing device is made up of spindle housing 1, clamping bolt 3, location-plate 4, supporting plate 6, torsionspring 7 and arc strut 8, it is characterized in that: the screw rod 9 that passes on left of spindle housing 1 is hinged with a supporting plate 6, uniformly in the heart in supporting plate 6 be manufactured with the installing hole 12 that four diameters are 11mm.Torsionspring 7 is equipped with at the middle part of screw rod 9, and torsionspring 7 is two, and one end of torsionspring 7 is close to the left side of spindle housing 1, and the other end of torsionspring 7 is close on supporting plate 6.The front side of spindle housing 1 is fixed with location-plate 4, location-plate 4 is fixed with a minor axis 10; The front side of supporting plate 6 is fixed with an arc strut 8 by clamping bolt 3, and arc strut 8 is manufactured with deep-slotted chip breaker, and deep-slotted chip breaker is sleeved on minor axis 10, and is fixed by the locking nut 2 of band Metallic rod 5.Described spindle housing 1 is fixedly mounted on car body mounting plane 13 by four bolts.(see accompanying drawing 1 ~ 8).
The course of work of this large-scale whip antenna entrucking folding focusing device is: the installing hole 12 that antenna is 11mm by four diameters that supporting plate 6 makes is fixed on supporting plate 6; When antenna is holded up, supporting plate 6 be placed in spindle housing 1 with spindle housing 1 close contact, and by band Metallic rod 5 locking nut 2 be fixed tightly on location-plate 4, even if now there is the effect of external force, locking nut 2 does not have the situation generation rotating and loosen yet, and therefore supporting plate 6 and spindle housing 1 also can not loosen.When wanting reclining radio antenna, unscrew locking nut 2 by Metallic rod 5 and supporting plate 6 and spindle housing 1 are unclamped, rotated together with supporting plate 6 by locking nut 2 and depart from spindle housing 1(see accompanying drawing 2, antenna is not shown in FIG.), the folding namely realizing antenna falls.
Acting as of two torsionsprings 7 installed in the middle part of the screw rod 9 of this large-scale whip antenna entrucking folding focusing device, when antenna is holded up, two torsionsprings 7 do not stress; When antenna folding falls, two torsionsprings 7 stop antenna to fall, and offset the moment of torsion of most of antenna folding generation of while falling, farthest can save operational personnel and manpower when installing and unload like this.When antenna folding falls, by the cooperation of locking nut 2 and arc strut 8, can make antenna in the scope of 0 ~ 90 ° at any angle folding fall and locking.
The above is preferred embodiment of the present utility model, above-mentioned illustrating does not do any pro forma restriction to flesh and blood of the present utility model, any simple modification that person of an ordinary skill in the technical field has done above embodiment according to technical spirit of the present utility model after having read this specification or distortion, and the technology contents of above-mentioned announcement may be utilized to be changed or be modified to the Equivalent embodiments of equivalent variations, all still belong in the scope of technical solutions of the utility model, and do not deviate from essence of the present utility model and scope.
