Abstract
The utility model provides a novel centering rod for surveying and mapping. Existing centering rods are inconvenient to use. The product comprises a centering rod body (1), wherein a U-shaped groove (2) is formed in the top of the centering rod body; U-shaped grooves are formed at the two ends of a vertical telescopic connecting rod; horizontal concentric holes are formed at the two ends of the U-shaped grooves; two opposite L-shaped grooves are formed at the ends of a horizontal telescopic connecting rod and form insertion connection pieces (3); horizontal concentric holes are formed in the insertion connection pieces; screws (4) pass through the horizontal concentric holes to be connected with nuts (5); positioning concentric holes are formed in the screws and the insertion connection pieces; the horizontal concentric holes are vertical to the positioning concentric holes; the positioning concentric holes are connected with positioning rods (6) through insertion; the positioning rods enable the included angle between the centering rod body and the horizontal telescopic connecting rod and the included angle between the vertical telescopic connecting rod and the horizontal telescopic connecting rod to be 90 degrees; a connecting hole is formed in the centering rod body and is connected with a bolt (7); the bolt is connected with a horizontal U-shaped fixator through insertion.

above-mentioned object realizes by following technical scheme:
a kind of novel mapping centering rod, its composition comprises: centering rod body, transversal stretching connecting link, vertical flexible connecting link, the top of described centering rod body has U-shaped groove, two ends of described vertical flexible connecting link all have described U-shaped groove, the two ends of described U-shaped groove have horizontal concentric hole, the end of described transversal stretching connecting link has 2 L-type grooves of supporting or opposing, 2 described L-type grooves of supporting or opposing form insert-connecting plate, described insert-connecting plate has described horizontal concentric hole, screw rod is through described horizontal concentric hole coupling nut, described screw rod and described insert-connecting plate have location concentric hole, described horizontal concentric hole is mutually vertical with described location concentric hole, described location concentric hole grafting backstay, described backstay makes described centering rod body and described transversal stretching connecting link, angle between described vertical flexible connecting link and described transversal stretching connecting link is 90 °, described centering rod body has connecting hole, described connecting hole coupling bolt, the described horizontal U-shaped fixator of bolt grafting.
described a kind of novel mapping centering rod, described U-shaped groove, described insert-connecting plate, described screw rod, described nut forms web member, described transversal stretching connecting link comprises horizontal expansion link and lower horizontal expansion link, described vertical flexible connecting link comprises vertical supporting bar and lower vertical expansion link, described centering rod body connects described lower horizontal expansion link by described web member, described lower horizontal expansion link connects described lower vertical expansion link by described web member, described lower vertical expansion link connects described upper horizontal expansion link by described web member, described upper horizontal expansion link connects described upper vertical supporting bar by described web member, the center of described upper vertical supporting Gan center and described centering rod body point-blank, described upper vertical supporting bar connects split type bluetooth dish, described upper vertical supporting bar connects L-type receiving antenna.
described a kind of novel mapping centering rod, the U-shaped fixator of described horizontal stroke comprises U-shaped shell fragment, the top of described U-shaped shell fragment connects L-type location-plate, the end of described U-shaped shell fragment has He You hole, left hole, described left hole is through described bolt, described right hole is installed with screw rod, and described screw rod connects locking cap, and described U-shaped shell fragment and described L-type location-plate are clamped transmitter.
beneficial effect:
1. the utlity model has structure and connect closely, can not produce loosening advantage, the transversal stretching connecting link of employing, vertically flexible connecting link can form horizontal U-shaped groove, also can be easy to use even if run in use eaves.
the location concentric hole that the utility model adopts can guarantee centering rod body and transversal stretching connecting link, vertically between flexible connecting link and transversal stretching connecting link, be connected to vertical connection, and it is concentric with split type bluetooth dish that assurance does not affect centering rod body.
it is more convenient to use that the locking by screw rod and locking cap of the U-shaped shell fragment of the utility model and L-type location-plate can clamp transmitter well.
