The connecting cylinder A is internally provided with a positioning sleeve A, the outer side of the connecting cylinder A is provided with a connecting plate A, the connecting cylinder A is matched and installed with the bar A through the positioning sleeve A, the center of the bottom of the connecting cylinder A is provided with a through hole and a key groove, the connecting cylinder A is installed with a connecting shaft through a key, the connecting shaft is connected with the small bevel gear through the key, the small bevel gear is fixed on the connecting shaft through a screw fastening shaft end retainer ring, and a sleeve is arranged between the connecting cylinder A on the connecting shaft and the; the small bevel gear is meshed with the large bevel gear, and the large bevel gear is fixed on the inner side of the connecting plate B through a set screw; the connecting plate B is arranged on the outer side of the connecting cylinder B and is positioned on the inner side of the connecting plate A, and a positioning sleeve B is arranged in the connecting cylinder B and is matched with the bar B through the positioning sleeve B; the connecting plate A and the connecting plate B are provided with through holes with the same structure and the same axle center, and the connecting plate A, the connecting plate B and the large bevel gear are installed and positioned through pin shafts.
Further, the positioning sleeve A and the positioning sleeve B are both made of materials which have certain elasticity and are compressible and have larger friction coefficients.
The utility model discloses the advantage and the positive effect that the device had:
1. this location connecting device utilizes bevel gear as the installation positioner between position sleeve A and the position sleeve B, can prevent effectively that rotation and slip from appearing when the rod receives the heavy load after connecting, and to a great extent has improved installation positioner's factor of safety.
2. The locating sleeve A and the locating sleeve B are compressible by certain elasticity and have large friction coefficient, so that the bar and the locating connecting device are convenient to compress and install, and meanwhile, the bar can be prevented from sliding after installation, and the surface of the bar cannot be damaged.
3. The utility model discloses the device is convenient for assemble and dismantle, adjustable rod connection angle.
Drawings
The device of the present invention will be further explained with reference to the drawings and the embodiments.
Figure 1 is a cross-sectional view of a preferred embodiment of the device of the present invention.
In the attached drawing, 1, bars A, 2, positioning sleeves A, 3, connecting cylinders A, 4, a connecting shaft, 5, a small bevel gear, 6, a pin shaft, 7, connecting plates A, 8, connecting cylinders B, 9, positioning sleeves B, 10, bars B, 11, a set screw, 12, a large bevel gear, 13, connecting plates B, 14, a screw fastening shaft end retainer ring, 15 sleeves, 16 and keys.
