DETAILED DESCRIPTION
[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0026] Example 1
[0027] Reference Figure 1 , 2, is the first embodiment of the utility model, which provides a connection structure of a robot arm, including a threaded connector 100, one side of the threaded connector 100 is fixedly connected to a universal shaft 101, one side of the universal shaft 101 is rotatably connected to a universal joint 102, a side of the universal shaft 101 away from the threaded connector 100 is fixedly connected to a small head clamp 200, a side of the small head clamp 200 away from the universal shaft 101 is slidably connected to a large head clamp 500, the upper surface of the large head clamp 500 is slidably connected to a fixing ring 600, the interior of the fixing ring 600 is fixedly connected to a spring 700, a side of the large head clamp 500 close to the small head clamp 200 is fixedly connected to a front ring 1100, and one side of the front ring 1100 is fixedly connected to a clamping block 800.
[0028] By connecting the robot body with the threaded connector 100, the small head clamp 200 and the large head clamp 500 on one side of the threaded connector 100 facilitate connecting the robot arm to the body. By squeezing toward the middle, the fixing ring 600 and the spring 700 move backwards. While moving backwards, the clamp block 800 on one side of the front ring 1100 moves upwards. Then, the small head clamp 200 is pushed so that the stop block 900 on one side of the small head clamp 200 exceeds the clamp block 800. Then, the L-shaped trapezoid will clamp the large head clamp 500 as a whole, so that the two clamps are fixedly connected. The two clamps can make the robot arm connection faster and more convenient, and there is no need to fix the connection bit by bit with bolts, which is more complicated to use.
[0029] Example 2
[0030] Reference Figures 2 to 4 , which is the second embodiment of the utility model. This embodiment is based on the previous embodiment. The small head clamp 200 is fixedly connected to the inside with an elastic member 300, the side of the elastic member 300 away from the small head clamp 200 is fixedly connected to a merging block 400, the upper surface of the small head clamp 200 is fixedly connected to a stopper 900, and a slot 1000 is opened on one side inside the fixing ring 600.
[0031] The elastic member 300 and the merging block 400 inside the small head clamp 200 can make the two clamps be pressed against each other and connected. The stop block 900 on the upper surface of the small head clamp 200 can clamp the clamp block 800 when the large head clamp 500 is pushed. The slot 1000 on one side of the fixing ring 600 can facilitate the pressing of the clamp block 800 when not connected.
[0032] Example 3
[0033] Reference Figures 2 to 4 , which is the third embodiment of the utility model, and this embodiment is based on the previous embodiment, the shape of the card block 800 is a rectangle, the card slot 1000 is adapted to the card block 800, the shape of the stop block 900 is an L-trapezoidal shape, and the stop block 900 is adapted to the card block 800.
[0034] The card block 800 is rectangular, and the card slot 1000 is adapted to the card block 800, so that the card block 800 can be supported. The stopper 900 is L-shaped, so that the card block 800 can be stuck when pushed and stuck, avoiding the phenomenon of being unstable.
