In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0024] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps described in these embodiments do not limit the scope of the utility model. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. 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.

[0025] 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. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0026] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0027] 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.

[0028] The utility model provides a quick-change structure, such as Figure 1-4 As shown, it includes a first connector 1 and a second connector 2, and corresponding plug-in holes 3 and plug-in components 4 are provided between the first connector 1 and the second connector 2. A movable locking component 5 is provided in the plug-in hole 3. When the locking component 5 moves inward, it can provide a plug-in space for the plug-in component 4 to be smoothly inserted into the plug-in hole 3. When the locking component 5 moves outward, it can limit and lock the plug-in component 4 in the plug-in hole 3 to prevent the first connector 1 and the second connector 2 from axially disengaging.

[0029] Specifically, the moving direction of the locking member 5 is perpendicular to the plug-in direction of the plug-in member 4. One end of the locking member 5 is a pressing end 6, and the end extends to the outside of the first connecting member 1. The other end is provided with an elastic member, that is, when the locking member 5 is pressed inward, the elastic force of the elastic member needs to be overcome. When the locking member 5 is released, the locking member 5 will be reset to the initial position under the action of the elastic member.

[0030] It should be noted that the moving direction of the locking member 5 and the plugging direction of the plug-in member 4 may also be designed at other angles, and those skilled in the art may make adaptive adjustments according to requirements, which will not be elaborated herein.

[0031] Furthermore, a matching limit block 7 and a limit groove 8 are provided between the locking member 5 and the connector 4. The inclined limit surface design between the limit block 7 and the limit groove 8 can reduce the resistance when the locking member 5 and the connector 4 move relative to each other, thereby ensuring the smoothness of the movement of the locking member 5.

[0032] A plurality of matching positioning guide holes 9 and positioning guide columns 10 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 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 11 is provided between the first connector 1 and the second connector 2 for achieving electrical connection with the outside, and the electrical connector 11 on one of the connectors has an elastic design, which can ensure the stability of the electrical connection.

[0033] It should be noted that the specific numbers of the positioning guide holes 9, the positioning guide pillars 10 and the electrical connectors 11 can be adjusted accordingly according to actual needs, which will not be elaborated herein.

[0034] 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.

[0035] When the quick-change structure of the utility model is used, the locking member 5 is first pressed inwardly by the pressing end 6 to overcome the elastic force of the elastic member, and the plug-in member 4 is inserted into the plug-in hole 3. At this time, the positioning guide hole 9 and the positioning guide column 10, as well as the electrical connector 11, are also matched accordingly. Then the locking member 5 is released, and the locking member 5 moves outward under the elastic force of the elastic member, so that the limit block 7 is stuck in the limit groove 8, and the plug-in member 4 can be locked in the limit position, thereby realizing the locking and matching between the first connector 1 and the second connector 2; when unlocking is required, the locking member 5 can be pressed again to pull out the plug-in member 4 along the axial direction, so as to realize the unlocking and separation between the first connector 1 and the second connector 2.

[0036] 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.
