[0004] The purpose of this invention is to provide a robotic arm that is easy to disassemble and maintain, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A robotic arm that is easy to assemble, disassemble, and maintain includes: a mechanical base and a small base. The robotic arm is fixedly connected to the top of the mechanical base, and a movable block is slidably connected to the top of the small base. Two connecting rods are rotatably connected to the top of the movable block, and the other ends of the two connecting rods are rotatably connected to locking blocks. The inner walls of the left and right sides of the mechanical base are provided with locking slots that match the locking blocks. The outer sides of the two locking blocks are movably inserted into the corresponding locking slots. A connecting block is fixedly connected to the bottom of the movable block, and a rectangular block is fixedly connected to the bottom of the small base. The top of the rectangular block is provided with a moving groove that matches the connecting block, and the outer side of the connecting block is slidably connected to the inner side of the moving groove.

[0007] Preferably, a small screw is rotatably connected to the inner wall of one side of the movable groove, the outer side of the small screw is threaded to the inner side of the connecting block, and a handwheel is fixedly connected to the outer side of the small screw. A block number is fixedly connected to one side of the rectangular block, and a bolt is threaded to the inner side of the block number. A plurality of insertion holes adapted to the bolts are opened on one side of the handwheel, and the outer side of the bolt is movably inserted into the inner side of the corresponding insertion hole.

[0008] Preferably, the top of the small base has two sliding grooves, and small blocks are slidably connected to the outer sides of the two sliding grooves. The tops of the two small blocks are fixedly connected to the bottom of the corresponding card blocks.

[0009] Preferably, a rising block is fixedly connected to the bottom of the rectangular block, a large screw is threadedly connected to the inner side of the rising block, a starter box is rotatably connected to the outer side of the large screw, a motor is fixedly connected to the inner front wall of the starter box, a worm gear is fixedly connected to the output end of the motor, a worm wheel meshes with the outer side of the worm gear, and the inner side of the worm wheel is fixedly connected to the outer side of the large screw.

[0010] Preferably, the top of the starter box is fixedly connected to two guide bars, and the inner sides of the two guide bars are slidably connected to the outer side of the rising block.

[0011] Preferably, the bottom of the starter box is fixedly connected with multiple support legs.

[0012] In this utility model, by placing the mechanical base on the surface of the small base, the handwheel is turned, which causes the small screw to start rotating. As the small screw rotates, the connecting block starts to move horizontally. Furthermore, the connecting block drives the moving block to move, which causes the connecting rod to start rotating, so that the locking block can be inserted into the inside of the mechanical base. At this time, the bolt is tightened with the first block.

[0013] In this invention, the bolts have been inserted into the corresponding round holes, thus completing the installation of the mechanical base. When adjusting the height of the device, the motor can be started, which causes the worm to start rotating. Since the worm meshes with the worm wheel, the large screw also starts rotating, which causes the rising block to start moving vertically, thereby adjusting the height of the device.

[0014] This utility model has a reasonable structural design. Through the cooperation between the moving block, connecting rod, rectangular block, small screw and locking block, the robotic arm can be easily installed with the small base, thereby improving the work efficiency of the staff.

The outer sides of the two locking blocks 5 are movably inserted into the corresponding locking slots. A connecting block 6 is fixedly connected to the bottom of the movable block 3. A rectangular block 7 is fixedly connected to the bottom of the small base 2. A movable groove adapted to the connecting block 6 is provided on the top of the rectangular block 7. The outer side of the connecting block 6 is slidably connected to the inner side of the movable groove.

[0021] In this embodiment, a small screw 8 is rotatably connected to the inner wall of one side of the movable groove. The outer side of the small screw 8 is threadedly connected to the inner side of the connecting block 6, and a handwheel 9 is fixedly connected to the outer side of the small screw 8. A block 10 is fixedly connected to one side of the rectangular block 7. A bolt is threadedly connected to the inner side of the block 10. A plurality of insertion holes adapted to the bolts are opened on one side of the handwheel 9. The outer side of the bolt is movably inserted into the inner side of the corresponding insertion hole. Two sliding grooves are opened on the top of the small base 2. Small blocks are slidably connected to the outer side of the two sliding grooves. The top of the two small blocks is fixedly connected to the bottom of the corresponding locking block 5, which makes the locking block 5 move more stably.

[0022] In this embodiment, a rising block 11 is fixedly connected to the bottom of the rectangular block 7. A large screw 13 is threadedly connected to the inner side of the rising block 11. A starting box 12 is rotatably connected to the outer side of the large screw 13. A motor 14 is fixedly connected to the inner front wall of the starting box 12. A worm gear 15 is fixedly connected to the output end of the motor 14. A worm wheel meshes with the outer side of the worm gear 15.

The inner sides of the two guide bars 16 are slidably connected to the outer side of the rising block 11. Multiple support legs are fixedly connected to the bottom of the starting box 12 to support the entire device.

[0023] In this embodiment, during use, the mechanical base 1 is placed on the surface of the small base 2. The handwheel 9 is then turned, causing the small screw 8 to rotate. As the small screw 8 rotates, the connecting block 6 begins to move horizontally. Furthermore, the connecting block 6 drives the moving block 3, causing the connecting rod 4 to rotate. This allows the locking block 5 to be inserted into the inside of the mechanical base 1. The bolt is then tightened onto the first block 10, and the bolt is now inserted into the corresponding round hole. This completes the installation of the mechanical base 1. When adjusting the device height, the motor 14 can be started, causing the worm gear 15 to rotate. Since the worm gear 15 meshes with the worm wheel, the large screw 13 also begins to rotate, causing the rising block 11 to move vertically, thereby adjusting the device height.
