The present invention, is not intended to limit the present invention.
Referring to accompanying drawing, radar a period of time rotating locking apparatus of the invention can be analyzed to two functions, one realizes a period of time
State switches, i.e., orientation is rotated；Two be the locking of a period of time and rotating mechanism.Therefore, the present invention can regard as and a set of can turn along 2 axles
Dynamic shafting component, first axle is the rotary shaft in a period of time, second rotary shaft for locking executing agency.Specifically, originally
Invention rotating locking apparatus mainly includes the rotating shaft assembly of a period of time rotating shaft assembly and locking executing agency, including, support is outer
Frame 4, outer shaft 1, internal axle sleeve 2 and 3, internal mandrel 5, propeller shaft sleeve 7, alignment pin 8, backing pin 11, spring bottom plate 9, connection bearing pin
10th, lower gasket 6, handle 12.
A period of time rotating shaft assembly
Wherein, a period of time rotating shaft assembly include support housing 4, outer shaft 1, internal axle sleeve 2 and 3, internal mandrel 5, backing pin 11,
Lower gasket 6.
Support housing 4 is the carrier of antenna element 100 and whole rotational locking device, generally elongate rod, and every elongated
Multiple antenna element 100 are evenly equipped with bar.
Outer shaft 1 mainly plays fixed support, and inner sleeve is played a supportive role.It is connected with support housing 4, under
End distribution is fluted, and number of positions is determined according to the orientation under a period of time working condition, and the groove, which is used to coordinate with alignment pin 8, to be locked
The effect of tightening position, limits the rotation of mandrel 5, and then has rotated position-limiting action to radar a period of time；The position that antenna element 100 is positioned
The position for being solely dependent upon groove is put, if necessary to change the position of positioning, it is only necessary to change the position of correspondence detent.
If equipped with the outer shaft 4 for there are multiple grooves, then multiple unknown positioning requirements easily can be simply realized, can be extensive
Be applied to it is various need the anglec of rotation position fields.
Internal axle sleeve, generally band are turned over all over copper sheathing or self-lubricating bearing, are embedded in outer shaft 1, and two ends respectively have one, respectively
For upper internal axle sleeve 2 and lower internal axle sleeve 3, play a part of support mandrel, upper internal axle sleeve 2 is turned over except playing a part of radial support
While there is the effect of one direction axial restraint；
Internal mandrel 5, installed in the inside of internal axle sleeve, axially position passes through the end face of Upper shaft sleeve 2 and the gear of the lower end of mandrel 5
Pin 11 and lower gasket 6 realize (can certainly be using the realization fixation of other mechanical structures, as long as axially position can be realized),
Backing pin 11 is radially across mandrel 5, and the mounting plane in a period of time is left in the upper end of mandrel 5, and lower end is provided with rectangular channel, and the rectangular channel is preferred
Plane is symmetrical where along mandrel center line, and the hole of vertical rectangle trough wall surface is provided with the side wall of rectangular channel, and rectangular channel is used to pacify
The rotary components of dress locking executing agency.
It is preferred that scheme in, groove the circumference of outer shaft have on step, step have downward grab, alignment pin
8 tops are also equipped with hook structure, and the top of alignment pin 8 is flexible structure, and the step of itself and recessed circumferential is omited when touching
Light deformation, into groove, then coordinates with grab on step and fixes, to prevent alignment pin from deviating from.During taking-up, downward power causes
Depart between the deforming tops of alignment pin 8, grab, and then deviate from groove.The hook structure is shallower hook, it is not necessary to excessive change
Shape can depart from.
Lock executing agency's rotating shaft assembly
Locking the rotating shaft assembly of executing agency includes propeller shaft sleeve 7, alignment pin 8, connection bearing pin 10.
In propeller shaft sleeve 7, the rectangular channel for being arranged on the lower section of mandrel 5, it is passed through in rectangle groove sidewall by connecting bearing pin 10
Hole be rotatably fixed.Blind hole is left in the side of propeller shaft sleeve 7, wherein can be inserted into handle 12, can make driving by operation handle
Axle sleeve 7 is rotated.
Described one end of alignment pin 8 is connected with propeller shaft sleeve 7, and the other end can be inserted into the groove of the outer shaft 1.Alignment pin
Axis that can be with propeller shaft sleeve 7 around connection bearing pin 10 rotates, while can also be with propeller shaft sleeve 7, connection bearing pin 10
Axis around mandrel 5 rotates.This rotation in both direction of alignment pin 8 so that it can pass in and out any groove of outer shaft 1
It is interior, realize that a period of time turns to specified location and locked.
Preferably, spring bottom plate 9 is additionally provided with, one end is fixed on the lower end of mandrel 5, and the other end is fixed on propeller shaft sleeve 7,
Material is spring steel, and spring bottom plate 9 has a upward spring force to propeller shaft sleeve 7 all the time so that alignment pin 8 will not be because of gravity
Or interference drops out groove.The presence of spring bottom plate 9 to alignment pin 8 not only for playing a part of fixed position.And driving
Moving axis set 7 pushes to discharge during alignment pin 8, plays a part of storing energy, after specified location is rotated to, unclamps drive shaft
Set, the energy being stored in spring bottom plate 9 is discharged so that the rapid return of alignment pin 8, can improve whole rotation-locking
The efficiency of the positioning of system.
Handle 12 may be inserted into the side blind hole of drive end axle sleeve 7, pushing and rotating by operation handle 12, Ke Yicao
Make above-described two shaftings, handle can Reusability in multiple propeller shaft sleeves 7, repeat multiple antenna element 100.
The operating method of handle is as follows：
1) handle 12 is inserted in propeller shaft sleeve 7, presses handle 12 downwards afterwards, make propeller shaft sleeve 7 around connection bearing pin 10
Center is rotated down, and then alignment pin 8 is departed from groove, spacing to be released from.
2) left-right rotation handle 12 so that propeller shaft sleeve 7, alignment pin 8 rotate around the axis of mandrel 5 together, pass through simultaneously
Mandrel 5 drives antenna element 100 to be rotated together along mandrel axis, as shown in Figure 3.
3) antenna element 100 goes to and needed after angle, as shown in figure 4, pushing up handle 12 or the work in spring bottom plate 9
Under, handle is extracted in the upward resilience of propeller shaft sleeve 7 so that alignment pin enters another groove, and a period of time reaches designated state and locked
It is fixed.
4) other antenna element 100 are applied with above-mentioned 1) -3) the same process of step.
To that will reset in a period of time, above procedure is repeated.
Finally it should be noted that：The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention,
