DETAILED DESCRIPTION

[0021] In order to make the technical means, technical features, purpose of the utility model and technical effects achieved by the utility model easier to understand, the utility model is further explained below with reference to specific illustrations.

[0022] like Figure 1 As shown, an adjustable connection device for a lighting fixture includes a base 1 and a connecting rod 2. The connecting rod 2 is connected to the upper end of the base 1. The connecting rod 2 can adjust the angle relative to the base 1, thereby adjusting the relative installation angle of the lamp 22.

[0023] like Figure 1-Figure 5 As shown, a mounting seat 3 is integrally processed at one end of the base 1 for mounting and connecting the connecting rod 2, and a mounting plate 25 is processed at the other end of the base 1, and the mounting connection with the ground is achieved through the mounting plate 25. The mounting seat 3 includes a first side plate 4 and a second side plate 5, which are installed relative to each other. An actuator 6 is installed on the outer side of the first side plate 4, and the protruding end of the actuator 6 penetrates the first side plate 4. First positioning teeth 7 are evenly distributed on the inner circumference of the first side plate 4. A first driver 8 is installed on the outer side of the second side plate 5, and the output shaft of the first driver 8 penetrates the second side plate 5. A driving block 12 is fixedly mounted on the output shaft of the first driver 8, and a plurality of driving teeth 13 are processed on the outer circumferential surface of the driving block 12. The plurality of driving teeth 13 are evenly distributed on the driving block 12.

[0024] The connecting rod 2 includes a connecting seat 10 and a mounting rod 11. The connecting seat 10 is installed between the first side plate 4 and the second side plate 5. The connecting seat 10 is evenly distributed on the circumference of the side wall of the first side plate 4 and is processed with second positioning teeth 9. The second positioning teeth 9 can be plugged into and positioned with the first positioning teeth 7. The extended end of the actuator 6 passes through the first side plate 4 and abuts against the connecting seat 10. The extension of the actuator 6 can push the connecting seat 10 to move toward the second side plate 5, thereby disengaging the first positioning teeth 7 and the second positioning teeth 9. The protruding end of the actuator 6 can slide relative to the connecting seat 10. A driving groove 14 is processed on the connecting seat 10. The driving groove 14 is adapted to the driving block 12 and the driving tooth 13, that is, the driving tooth 13 can be inserted into the driving groove 14 and can slide relative to the mounting seat 3. When the actuator 6 pushes the mounting seat 3 to move and disengage the first positioning tooth 7 and the second positioning tooth 9, the first driver 8 can drive the connecting seat 10 to rotate and adjust relative to the mounting seat 3 through the cooperation of the driving block 12 and the driving tooth 13 with the driving groove 14.

[0025] like Figure 3As shown, at least two arc-shaped long grooves 15 are processed on the second side plate 5. In this embodiment, the number of the arc-shaped long grooves 15 is two as an example for explanation. The two arc-shaped long grooves 15 are evenly distributed on the circumference of the second side plate 5 and are coaxially distributed with the first driver 8. A guide rod 16 adapted to the arc-shaped long groove 15 is installed on the side wall of the connecting seat 10 facing away from the second positioning tooth 9. The two guide rods 16 are respectively inserted into and connected to the two arc-shaped long grooves 15 and can slide along the arc-shaped long grooves 15. The long slot 15 is used to limit and guide the rotation of the connecting seat 10. A spring 17 is mounted on the guide rod 16. One end of the spring 17 abuts against the connecting seat 10, and the other end of the spring 17 abuts against the second side plate 5. When the first driver 8 drives the connecting seat 10 to be adjusted into place, the actuator 6 retracts, and the connecting seat 10 moves toward the first side plate 4 under the action of the spring 17, so that the first positioning tooth 7 and the second positioning tooth 9 are reinserted into the locking position, thereby fixing the position of the connecting seat 10 relative to the mounting seat 3.

[0026] like Figures 1-4 As shown, the interior of the mounting rod 11 is hollow, and a telescopic rod 18 is installed in the hollow interior of the mounting rod 11. The telescopic rod 18 can slide and retract relative to the mounting rod 11. Specifically, a bar-shaped tooth 19 is processed on the telescopic rod 18, and a second driver 20 is installed on one side of the end of the mounting rod 11. A pinion 21 is fixedly connected to the output shaft of the second driver 20. The pinion 21 meshes with the bar-shaped tooth 19. The second driver 20 drives the pinion 21 to rotate. The engagement of the pinion 21 with the bar-shaped tooth 19 drives the telescopic rod 18 to move relative to the mounting rod 11. The lamp 22 is installed at the end of the telescopic rod 18 away from the connecting seat 10. The length direction of the lamp 22 is adjusted by the extension and retraction of the telescopic rod 18 relative to the mounting rod 11.

[0027] A limiting groove 23 is processed on the side wall of the mounting rod 11, and the limiting groove 23 passes through two opposite side walls of the mounting rod 11. A limiting rod 24 is processed on the two side walls of the telescopic rod 18, and the limiting rod 24 is slidably connected in the limiting groove 23. Through the sliding fit of the limiting rod 24 in the limiting groove 23, the position of the telescopic rod 18 extending out of the mounting rod 11 is limited, thereby preventing the telescopic rod 18 from extending excessively and falling out of the mounting rod 11.

[0028] The actuator 6 is an air cylinder, an oil cylinder or an electric push rod, and the first driver 8 and the second driver 20 are servo motors or hydraulic motors.

[0029] The working principle of this utility model is:

[0030] When in use, the actuator 6 extends, overcomes the thrust of the spring 17 and pushes the connecting seat 10 to move toward the second side plate 5, so that the first positioning tooth 7 and the second positioning tooth 9 are disengaged, and the first driver 8 is started. The driving tooth 13 and the driving slot 14 cooperate to drive the connecting rod 2 to rotate relative to the mounting seat 3, adjust the angle of the connecting rod 2 relative to the base 1, and thus realize the adjustment of the installation angle of the lamp 22. The angle of each rotation of the connecting seat 10 is determined according to the number of the first positioning teeth 7 and / or the second positioning teeth 9. After the adjustment is in place, the actuator 6 retracts, and the force of the spring 17 pushes the connecting seat 10 to move toward the first side plate 4, so that the first positioning teeth 7 and the second positioning teeth 9 are re-inserted and positioned, fixing the relative position of the connecting rod 2 and the base 1;

[0031] Start the second driver 20, which drives the pinion 21 to rotate. Through the engagement of the pinion 21 with the bar teeth 19, the telescopic rod 18 is driven to move relative to the mounting rod 11, thereby adjusting the length direction of the lamp 22. The limit rod 24 cooperates with the limit slot 23 to limit the movement adjustment of the telescopic rod 18.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. In other words, any equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the technical scope of the present invention.
