Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0027] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description.

[0029] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0030] The utility model provides a quick-change structure, such as Figure 1-4 As shown, it includes a first connecting member 1 and a second connecting member 2, which are positioned and plugged together by a matching plug-in column 3 and a plug-in tube 4, and a plurality of slidingly matched locking members 5 are arranged on the circumference of the plug-in column 3. The plug-in tube 4 has a locking groove 6 corresponding to the locking member 5. The locking member 5 can extend into the locking groove 6 after the first connecting member 1 and the second connecting member 2 are positioned and plugged together, and the plug-in tube 4 can be limited and locked on the plug-in column 3 to prevent the first connecting member 1 and the second connecting member 2 from axially disengaging.

[0031] Specifically, the locking member 5 adopts a spherical structure, and a piston rod 7 that cooperates with the inclined surface of the locking member 5 is arranged in the plug-in column 3. The piston rod 7 is connected to the driving rod 9 through a transmission rod 8. The two ends of the transmission rod 8 are respectively hinged on the piston rod 7 and the driving rod 9. When the driving rod 9 moves left and right, the piston rod 7 can be driven to move up and down through the transmission rod 8. When the piston rod 7 moves downward, the locking member 5 is ejected and limited. When the piston rod 7 moves upward, the limit of the locking member 5 is released. Specifically, the moving direction of the driving rod 9 is perpendicular to the axial direction, and one end of the driving rod 9 is a pressing end 10, which extends to the outside of the first connecting member 1, and the other end is provided with an elastic member, that is, when the driving rod 9 is pushed inward by the pressing end 10, the elastic force of the elastic member needs to be overcome. When the pressing end 10 is released, the driving rod 9 will be reset to the initial position under the action of the elastic member.

[0032] It should be noted that the moving direction and the axial direction of the driving rod 9 can also be designed at other angles, and those skilled in the art can make adaptive adjustments according to needs, which will not be elaborated here.

[0033] Furthermore, a matching limit pin 11 and a limit groove 12 are provided between the driving rod 9 and the first connecting member 1 to limit the left and right movement stroke of the driving rod 9. A limit protrusion 13 is provided above the locking groove 6. The upper and lower sides of the limit protrusion 13 are both inclined surfaces designed to match the locking member 5, which can reduce the resistance when the plug-in tube 4 and the plug-in column 3 move relative to each other, and ensure the smoothness of the plug-in tube 4 when being plugged in and out.

[0034] A plurality of matching positioning guide holes 14 and positioning guide columns 15 are further provided between the first connector 1 and the second connector 2, which can not only play a positioning and guiding role, but also can further ensure that no radial relative movement occurs between the first connector 1 and the second connector 2, thereby ensuring the stability of the connection between the first connector 1 and the second connector 2. A matching electrical connector 16 is provided between the first connector 1 and the second connector 2 for achieving electrical connection with the outside, and the electrical connector 16 on one of the connectors has an elastic design, which can ensure the stability of the electrical connection.

[0035] It should be noted that the specific numbers of the positioning guide holes 14 , the positioning guide posts 15 and the electrical connectors 16 can be adjusted accordingly according to actual needs, which will not be elaborated herein.

[0036] The utility model also provides a robot, comprising the above-mentioned quick-change structure and a mechanical arm, wherein the free end of the mechanical arm is connected to the first connecting member 1, and the second connecting member 2 is used for connecting an electrical device.

[0037] When the quick-change structure of the utility model is used, the driving rod 9 is first pressed inwardly by the pressing end 10 to overcome the elastic force of the elastic member, and the driving rod 9 drives the piston rod 7 to move upward through the transmission rod 8, that is, the inclined surface of the bottom of the piston rod 7 that cooperates with the locking member 5 moves upward from the abutment position with the locking member 5, thereby moving away from the locking member 5. At this time, the plug-in cylinder 4 is plugged into the outer side of the plug-in column 3. During the plug-in, the limiting protrusion 13 can push the locking member 5 to move inward, that is, the locking member 5 will not affect the plug-in action, and at the same time, the positioning guide hole 14 and the positioning guide column 15, as well as the electrical connector 1 6 also cooperates accordingly, and then the pressing end 10 is released, the driving rod 9 moves outward under the elastic force of the elastic member, and the piston rod 7 is driven to move downward through the transmission rod 8. The bottom inclined surface of the piston rod 7 abuts against the locking member 5, and pushes the locking member 5 to extend outward along the vertical axial direction into the locking groove 6, so as to achieve the limited locking of the plug-in cylinder 4, thereby realizing the locking cooperation between the first connecting member 1 and the second connecting member 2; when unlocking is required, the driving rod 9 is pressed again to pull out the plug-in cylinder 4 along the axial direction, so as to realize the unlocking and separation between the first connecting member 1 and the second connecting member 2.

[0038] To sum up, the utility model provides a quick-change structure and a robot using the structure, which has a simple structure and is easy to operate, realizes the quick-change function of the free end of the robotic arm, has the advantages of stable connection, high replacement efficiency, and a wide range of applications, has great market value, and deserves to be widely promoted and applied.
