[0025] Please see Figs. 1-6 This utility model provides the following technical solution: a robot retractable robotic arm, including a base 1, a main arm body 2, a rotary joint 3, a connecting seat 4, a telescopic arm 5, a protective structure 6, and set screws 7. The protective structure 6 is fixedly connected to the connecting seat 4 by multiple set screws 7. The protective structure 6 includes a cover 601, a protruding plate 602, a rotating shaft 603, a connecting plate 604, a horizontal plate 605, a third magnetic block 606, a cooling fan 607, and an air inlet 608. One end of the cover 601 is fixedly installed on the connecting seat 4 by set screws 7. Two protruding plates 602 are symmetrically arranged on the left and right sides of the other end of the cover 601. A rotating shaft 603 is movably connected between the two protruding plates 602. A connecting plate 604 is fixedly connected to the rotating shaft 603. A second magnetic block 6041 is fixedly connected to the outer side of the connecting plate 604. A horizontal plate 605 is fixedly connected to both the upper and lower ends of the connecting plate 604. A third magnetic block 606 is symmetrically arranged on each of the horizontal plates 605.

[0026] A cooling fan 607 is provided at the center of the top of the cover 601, and an air inlet 608 is provided at the bottom of the cover 601, which is located below the cooling fan 607.

[0027] The cover 601 has a first magnetic block 6011 on both the left and right sides of one end, and the first magnetic block 6011 can be attracted and connected to the second magnetic block 6041 on the connecting plate 604.

[0028] The protective structure 6 fixedly installed on the connecting seat 4 allows the telescopic arm 5 to be completely housed within the protective structure 6, thereby protecting the working head of the telescopic arm 5 and preventing wear and tear due to accidental collisions when not in use, thus affecting its use. The cooling fan 607 provided on the protective structure 6 accelerates heat dissipation at the telescopic part of the robotic arm, ensuring stable operation of the robotic arm during retraction.

[0029] The main boom 2 is fixedly connected to the center of the upper end of the base 1. The upper end of the main boom 2 is movably connected to a rotary joint 3. The upper end of the rotary joint 3 is movably connected to a connecting seat 4. The front end of the connecting seat 4 is fixedly connected to a telescopic boom 5. The protective structure 6 covers the outside of the telescopic boom 5.

[0030] The telescopic boom 5 includes a telescopic cylinder 501, a mounting base 502, a connecting arm 503, and an end effector 504. One end of the telescopic cylinder 501 is fixedly connected to the connecting base 4. The mounting base 502 is fixedly connected to the front end of the inner rod of the telescopic cylinder 501. The connecting arm 503 is movably mounted on the mounting base 502. The end effector 504 is movably mounted on the front end of the connecting arm 503.

[0031] The telescopic cylinder 501 is installed inside the cover 601, and the end effector 504 is installed inside the protective cover formed by the adsorption connection of the left and right connecting plates 604 and the horizontal plate 605.

[0032] The magnetic connection design between the horizontal plates 605 facilitates the opening and closing of the connecting plate 604, making operation simple, convenient, and easy to use.

[0033] The working principle and usage process of this utility model are as follows: In specific use, by flipping the two connecting plates 604, the two connecting plates 604 are rotated 180° in opposite directions, so that the second magnetic block 6041 on the connecting plate 604 is attracted and fixed to the first magnetic block 6011, so that the working head on the telescopic arm 5 is exposed. The robotic arm can then perform repetitive actions according to the work. At the same time, the cooling fan 607 is started, and the air inside the cover 601 is exhausted to the outside through the cooling fan 607, thereby accelerating the air circulation and the heat dissipation of the telescopic components. This avoids the heat generated by frequent telescopic friction from affecting the stable operation of the robotic arm. After the robotic arm is used, the horizontal plate 605 on the two connecting plates 604 is closed again and attracted and fixed by the third magnetic block 606. Then, the working head is put into the cover formed by the connecting plate 604 and the horizontal plate 605, which protects the working head and avoids accidental collision and wear.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
