[0037] Furthermore, if Figure 2 As shown, the first connector 10 includes a housing 11 and a plug-in groove 12. The housing 11 can be fixed on a manipulator mounting seat or an operating platform, and can form the plug-in groove 12; the plug-in groove 12 is arranged in the housing 11, and is arranged axially. When in use, when installing the manipulator, the second connector 11 can be inserted into the plug-in groove 12 along the axial direction, thereby installing the manipulator; when disassembling the manipulator, the second connector 11 can be pulled out of the plug-in groove along the axial direction, thereby disassembling the manipulator.

[0038] Specifically, the housing 11 can be made of plastic, metal, or wood. It can be in the shape of a cuboid, a cylinder, a cube, or other shapes. In the present embodiment, preferably, the housing is in the shape of a cuboid, and the side wall of the housing 11 and the plug-in groove 12 facing away from each other can be connected to a mounting seat or an operating platform for mounting a manipulator. It can be understood that in some other embodiments, the other side walls of the housing 11 can also be connected to a mounting seat or an operating platform for mounting a manipulator.

[0039] The plug-in groove 12 may be in the shape of a dovetail, a cuboid, or a cube. In the present embodiment, preferably, the plug-in groove 12 is in the shape of a dovetail. It is understandable that in some other embodiments, the shape of the plug-in groove 12 is not limited to the dovetail, and it may be in other shapes. The plug-in groove 12 is provided for the second connector 20 to be plugged and fixed. The plug-in groove 12 has an opening extending from one end of the housing 11 toward the side wall of the housing 11, which can facilitate the axial insertion of the second connector 20 to achieve the connection between the first connector and the second connector.

[0040] In this embodiment, a first guide groove 13 is provided on the inner side wall of the plug-in groove 12, and the first guide groove 13 can guide the locking assembly. The first guide groove 13 is radially arranged on the inner side wall of the plug-in groove 12. In this embodiment, specifically, the first guide groove 13 is arranged in the middle of the inner side wall along the length direction of the shell 11, and the locking assembly can be locked and fixed along the length direction. Of course, it can be understood that in some other embodiments, the first guide groove 13 is not limited to being arranged along the length direction of the shell 11, and it can also be arranged along the width direction of the shell 11.

[0041] In this embodiment, the inner side wall of the plug groove 12 is further provided with a second guide groove 14, and the second guide groove 14 can guide the insertion of the second connector 20. The second guide groove is arranged along the axial direction of the plug groove 12. In this embodiment, it is arranged perpendicular to the first guide groove 13.

[0042] In this embodiment, a socket 15 is provided in the plugging groove 12. The socket 15 is arranged at the bottom of the plugging groove 12 and protrudes toward the plugging groove 12. The socket 15 includes a plurality of sockets arranged side by side. Specifically, the plurality of sockets are arranged side by side along the length direction of the housing 11. By providing the socket 15, the first connector 10 and the second connector 20 can be electrically connected. Of course, it can be understood that in some other embodiments, the socket 15 can be omitted.

[0043] like Figure 3 As shown, the second connector 20 can be made of metal, plastic, wood and other materials, and includes a connector 21 and a plug-in protrusion 22; the connector 21 can be used to connect with a manipulator. Of course, it can be understood that in some other embodiments, the connector 21 is not limited to connecting with a manipulator, and it can also be connected with other mechanical parts. The plug-in protrusion 22 is connected to the connector 21, is integrally formed with the connector 21, and is arranged corresponding to the plug-in groove 12, and can be inserted into the plug-in groove 12 to achieve a fixed connection between the first connector 10 and the second connector 20.

[0044] Specifically, in this embodiment, the width of the connecting portion 21 is greater than the width of the plug-in protrusion 22, and it can be in the shape of a flat plate; of course, in some other embodiments, the width of the connecting portion 21 can also be less than the width of the plug-in protrusion 22, and its shape is not limited to a flat plate. The connecting portion 21 can be connected to a manipulator or a mechanical component by screw connection.

[0045] The plug-in protrusion 22 is arranged on the side wall of the connecting portion 21, and its height is adapted to the height of the connecting portion 21. It protrudes from the connecting portion 21. The shape and size of the plug-in protrusion 22 are adapted to the shape and size of the plug-in groove 12, so as to facilitate insertion into the plug-in groove and improve the stability of the connection. The shape of the plug-in protrusion 22 can be dovetail, rectangular, cube or other shapes. In this embodiment, preferably, the shape of the plug-in protrusion 22 is dovetail.

[0046] The plug-in protrusion 22 is provided with a conductive terminal 23 that is plugged and electrically conductive with the plug hole 15; the conductive terminal 23 is arranged at one end of the plug-in protrusion 22, and the number and arrangement of the conductive terminal 23 are adapted to the number and arrangement of the plug hole 15. Specifically, the conductive terminal 23 includes a plurality of terminals arranged side by side. When the conductive terminal 23 is inserted into the plug hole 15, the first connector 10 and the second connector 20 can be electrically connected.

[0047] like Figures 2 to 6 As shown, the locking assembly includes a hook 221, a buckle 321 and a driving mechanism 30; the hook 221 is arranged on the plug-in protrusion 22, and is arranged corresponding to the buckle 321, and can be buckled with the buckle 321; the buckle 321 is arranged in the plug-in groove 12, and can perform telescopic movement in the plug-in groove 12, and then move closer to or away from the hook 221, so as to achieve buckling or separation with the hook 221, thereby achieving the locking or unlocking of the first connector 10 and the second connector 20. The driving mechanism 30 is connected to the buckle 321, and can push the buckle 321 to perform reciprocating movement, and buckle or separate with the hook 221. When installing the manipulator, the hook 221 is inserted along the second guide groove so that the plug-in protrusion 21 is inserted into the plug-in groove 12 along the axial direction. By driving the driving mechanism, the buckle 321 is driven to move in a direction away from the hook 221 so that the plug-in protrusion 21 is completely inserted into the plug-in groove 12. Then the driving mechanism is released, and the driving mechanism drives the buckle 321 to move in the direction of the hook 221 and engages with the hook 221, so that the first connecting member 10 and the second connecting member 20 are fixedly connected, thereby achieving rapid installation. When disassembling the manipulator, the driving mechanism is driven to drive the buckle 321 to move in a direction away from the hook 221, and the buckle 321 is separated from the hook 221, and the plug-in protrusion 21 is pulled out of the plug-in groove 12, thereby achieving rapid disassembly.

[0048] Specifically, the hook 221 is arranged on the side of the plug-in protrusion 22 opposite to the connecting portion 21, the hook 221 protrudes from the side wall of the plug-in protrusion 22, and is arranged along the axial direction, and can be inserted along the second guide groove 14, the position of the hook 221 corresponds to the position of the second guide groove 14, and it can extend from the second guide groove 14 to facilitate fixing the first connecting member and the second connecting member. In this embodiment, the hook 221 includes a hook portion 2212 and a rod portion 2211 connected to the hook portion 2212; the rod portion 2211 is arranged along the height direction of the plug-in protrusion 22, and is in the shape of a long strip, and can be integrally formed with the hook portion 2212. The hook portion 2212 is arranged at one end of the rod portion 2211, and can be in the shape of a wedge. A first inclined surface 2213 is provided on it, and the first inclined surface 2213 is formed on the end surface where the hook portion 2212 and the rod portion 2211 meet. The first inclined surface 2213 can be fitted with the buckle 321. Of course, it can be understood that in some other embodiments, the shape of the hook portion 2212 is not limited to a wedge shape, and the end surface thereof connected to the rod portion 2211 is not limited to an inclined surface.

[0049] In this embodiment, the buckle 321 can be integrally formed with the driving mechanism 30, and the buckle 321 can be extended from the first guide groove 13, and can reciprocate in the first guide groove 13, and its shape is adapted to the shape of the hook 2212. Specifically, the buckle 321 can be wedge-shaped. A second inclined surface 3211 is provided on it, which is parallel to the first inclined surface 2213. The second inclined surface 2213 is located on the bottom surface of the buckle 321, and can be in contact with the first inclined surface 2213. The buckle 321 moves closer to the hook portion 2212, and the buckle 321 is easily misplaced, so that there is a deviation between the fitting surface thereof and the fitting surface of the hook portion 2212, resulting in that the buckle 321 and the hook portion 2212 cannot be tightly fastened. By setting the first inclined surface 2213 and the second inclined surface 3211, the deviation can be reduced, thereby improving the stability of the fastening of the buckle 321 and the hook portion 2212.

[0050] For example Figure 6As shown, the driving mechanism 30 is arranged along the length direction of the housing 11, and is arranged parallel to the first guide groove 13, and can drive the buckle 321 to slide in the first guide groove 13. It includes a button 31, a push rod 32 and an elastic member 33; the button 31 can extend from the housing 11 to the outside of the housing 11, and the button 31 can be made of plastic or metal, and can be cylindrical, one end of which is connected to the elastic member 33, and a connecting rod connected to the elastic member 33 is provided on it; the push rod 31 is connected to the button 31, specifically, it can be integrally formed with the button 31, and it is radially extended into the housing 11 and is arranged parallel to the first guide groove 13. The buckle 321 is arranged on the push rod 32 and is integrally formed with the push rod 32. One end of the elastic member 33 is connected to the button 31, and the other end abuts against the inner wall of the housing 11. In this embodiment, the elastic member 33 can be a spring, and the spring can be sleeved on the connecting rod of the button 31. When the button is pressed, the push rod 32 can drive the buckle 321 to move away from the hook 221, thereby separating from the hook 221. When the button is released, the push rod drives the buckle 321 to move closer to the buckle 321, thereby achieving the buckle 321 and the hook 322 buckling.

[0051] It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the coverage of the claims of the present invention.
