Abstract
The invention discloses an axial-locking device for a radar antenna, which comprises a lock handle (1), a lock shaft (2) and a lock pad (3). The lock handle (1) is a cam with a handle, and the lock shaft (2) is a T-shaped pin with one end provided with threads. When the axial-locking device is not used, the lock handle (1) and the lock shaft (2) are connected, and the lock handle (1) rotates around one end of the lock shaft (2) while the lock pad (3) is separated from the lock shaft (2). When in use of the axial-locking device, the lock shaft (2) penetrates through an antenna support rod to be locked, part of the end with threads of the lock shaft (2) is connected with a base lug to be fixed, and locking force can be regulated according to the depth of the threads of the lock shaft (2) screwing into the base lug. The axial-locking device is compact in structure, small in size, adjustable in locking force, reliable in locking and convenient in use and operation, and the service requirements during battles can be met by the integral design of the axial-locking device.
Description
Technical field
The present invention relates to a kind of locking device, particularly a kind of axial locking that is used for radar antenna.
Background technology
The light weapons system general weight of radar antenna is little; Between several kilograms to tens kilograms; The conversion of radar antenna work for ease and collecting state no longer increases complicated lockover device again, adopts the form of bolt form or stop pin mechanism to carry out the fixing of antenna usually.
The bolt form is that antenna is turned to work/favorite places, utilizes bolt then, realizes the conversion of antenna work and favorite places.During use, need use instrument, and operation is more loaded down with trivial details, each a lot of bolt of dismounting is sometimes also lost the part bolt easily.
The form of stop pin mechanism is carried out antenna fixedly the time, antenna is turned to work/favorite places at every turn, then stop pin is inserted pin-and-hole and fixes, and realizes the conversion of antenna work and rollover states.The exigent machining accuracy of this mode, if precision has deviation slightly, fixing of antenna is just very difficult.And bearing pin is unfavorable for regular repeated disassembled and assembled, and this makes and the bearing pin serious wear causes Antenna Positioning inaccurate.
These fixed form operations are got up all more loaded down with trivial details, and all need use instrument, can't realize manually locking fast, are unfavorable for fighting.
Summary of the invention
The object of the present invention is to provide a kind of axial locking that is used for radar antenna, solve present connection fixed form complex operation, dismounting difficulty, locate problem inaccurate, that need specialist tools and can't satisfy quick war fighting requirement.
A kind of axial locking that is used for radar antenna comprises: lock handle, lock shaft and lock pad.Lock handle is a cam with handles; Lock shaft is TOE " T type " bearing pin, and "-" part is threaded with the position that " | " part intersects, and "-" part of lock shaft places in the installing hole of lock handle, and rotates relatively freely; Lock pad is the annular pressing plate that has reinforcement, and the loading surface of lock pad is an arc, cooperates fully with the cam curved surface of lock handle, and " | " part of lock shaft places the hole of lock pad, and a threaded end face is higher than the lock pad end face.
When locking device did not use, lock handle and lock shaft were in connection status, lock handle rotation around the lock shaft end, and lock pad and lock shaft are in released state.
When locking device uses, lock shaft is passed the antenna pole that needs locking, the threaded part in lock shaft end is connected with the fixing pedestal journal stirrup of needs, and the depth of thread that gets into the pedestal journal stirrup through the rotation lock shaft is regulated coupling mechanism force.Downward pressing lock handle, the rotation of lock handle head cam mechanism holds out against lock pad, and lock pad compresses the pole end face to the motion of antenna pole direction, thereby realizes the upset and the locking of antenna.When needs unclamp, upwards lift lock handle, lock pad is unclamped in the rotation of lock handle head cam mechanism, and lock pad loosens the pole end face to the counter motion of antenna pole, and antenna freely overturns.
The present invention be applicable to that the light weight radar antenna does to require wartime fast, locking reliably, lock pad adopts high-abrasive material, increases the contact area with lock handle head cam mechanism, thereby increases the frictional force of whole locking device, guarantees that locking is reliable.Compact conformation, the volume of device are little in addition, coupling mechanism force is adjustable, use is easy to operate, adopt integrated design to satisfy the instructions for use of doing wartime.

Embodiment
A kind of axial locking that is used for radar antenna comprises: lock handle 1, lock shaft 2 and lock pad 3.Lock handle 1 is a cam with handles; Lock shaft 2 is TOE " T type " bearing pin, and "-" part is threaded with the position that " | " part intersects, and "-" part of lock shaft 2 places in the installing hole of lock handle 1, and rotates relatively freely; Lock pad 3 is for having the annular pressing plate of reinforcement, and the loading surface of lock pad 3 is an arc, cooperates fully with the cam curved surface of lock handle 1, and " | " part of lock shaft 2 places the hole of lock pad 3, and a threaded end face is higher than lock pad 3 end faces.
When locking device did not use, lock handle 1 was in connection status with lock shaft 2, lock handle 1 rotation around lock shaft 2 ends, and lock pad 3 is in released state with lock shaft 2.
When locking device uses, lock shaft 2 is passed the antenna pole that needs locking, the threaded part in lock shaft 2 ends is connected with the fixing pedestal journal stirrup of needs, and the depth of thread that gets into the pedestal journal stirrup through rotation lock shaft 2 is regulated coupling mechanism force.Pressing lock is 1 downwards, and the rotation of lock handle 1 head cam mechanism holds out against lock pad 3, and lock pad 3 compresses the pole end face to the motion of antenna pole direction, thereby realizes the upset and the locking of antenna.When needs unclamp, upwards lift lock handle 1, lock pad 3 is unclamped in the rotation of lock handle 1 head cam mechanism, and lock pad 3 loosens the pole end face to the counter motion of antenna pole, and antenna freely overturns.
