[0027] 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.
[0028] 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.
[0029] 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.
[0030] Example 1
[0031] Reference Figure 1 to Figure 4 , which is the first embodiment of the utility model, provides a locking structure, which includes a load-bearing component 100 composed of a mounting body 101, a connecting member 102 and a fixing body 103, and a limiting component 200 composed of a limiting member 201, a trigger member 202 and a positioning buckle 203.
[0032] Specifically, the connecting member 102 is provided with a positioning groove 102a, the fixed body 103 is provided with a limited movement hole 103a, the limiting member 201 is arranged in the mounting body 101, and includes a follower 201a and an extrusion member 201b. The follower 201a is arranged in the mounting body 101. In the initial state, the follower 201a is placed in the limited movement hole 103a, so that the mounting body 101 and the fixed body 103 remain in a relatively static state. The extrusion member 201b is arranged in the mounting body 101 and is engaged with the follower 201a, ensuring that the follower 201a can drive the extrusion member 201b to move in the horizontal direction, but does not affect the free movement of the extrusion member 201b in the vertical direction. The trigger member 202 is arranged in the mounting body 101, and the trigger member 202 One end is arc-shaped and extends into the mounting hole 101a provided on the mounting body 101. After the connecting member 102 enters the mounting hole 101a, it contacts the trigger member 202, which can push the trigger member 202 to move. The other end of the trigger member 202 is connected to the pushing groove 201a-1 provided on the follower 201a. The trigger member 202 can push the pushing groove 201a-1 to drive the follower 201a to move. The positioning buckle 203 is arranged in the mounting body 101 and can limit the connecting member 102 by entering the positioning groove 102a. At the same time, the end of the positioning buckle 203 away from the positioning groove 102a contacts the inclined surface 201b-1 of the extrusion member 201b, and will move with the movement of the extrusion member 201b, thereby driving the positioning buckle 203 to move.
[0033] When in use, the connecting piece 102 is connected to the robotic arm. After the connecting piece 102 enters the mounting hole 101a on the mounting body 101, it contacts the arc end of the trigger piece 202, causing the trigger piece 202 to move. When the other end of the trigger piece 202 contacts the pushing groove 201a-1, the pushing groove 201a-1 is subjected to force to drive the follower 201a to move, thereby driving the extrusion piece 201b engaged with the follower 201a to move. The inclined surface 201b-1 of the extrusion piece 201b squeezes the positioning buckle 203, causing the positioning buckle 203 to enter the positioning groove 102a of the connecting piece 102. When the positioning buckle 203 completely enters the positioning groove 102a, one end of the follower 201a located in the limiting hole 103a completely leaves the limiting hole 103a. At this time, the mounting body 101 and the fixed body 103 are released from the relative static state and can move.
[0034] In summary, this solution uses the limitation between the limiting piece 201 and the limiting hole 103a to limit the installation body 101 from being moved when the connecting piece 102 of the robot arm is not installed in place, thereby avoiding accidental startup of the robot arm when it is not installed in place, causing damage to the robot arm and personnel, and the installation of the robot arm on the column can be completed by only inserting the connecting piece 102, which is simple and convenient.
[0035] Example 2
[0036] Reference Figure 1 to Figure 4, which is the second embodiment of the present utility model, this embodiment provides a locking structure. Different from the previous embodiment, this embodiment provides a locking structure including an elastic member 204 and an unlocking member 205.
[0037] Specifically, elastic members 204 are provided on both the follower 201a and the positioning buckle 203, and the elastic member 204 is fixedly connected to the inner wall of the mounting body 101. The unlocking member 205 is provided on the mounting body 101, and the unlocking member 205 includes an unlocking cover 205a and an operating block 205b, and the operating block 205b is provided on the unlocking cover 205a.
[0038] Preferably, the unlocking cover 205a is arranged correspondingly in position and size to the extruding member 201b.
[0039] During use, when the robotic arm needs to be disassembled, the unlocking cover 205a is removed through the operating block 205b to release the moving space of the extrusion piece 201b. At this time, the elastic piece 204 on the positioning buckle 203 releases the elastic force, driving the positioning buckle 203 and the extrusion piece 201b that conflicts with the positioning buckle 203 to move toward the released moving space, and moving the positioning buckle 203 out of the positioning groove 102a, thereby unlocking. When the connecting piece 102 moves out of the mounting hole 101a, the unlocking cover 205a is installed to push the extrusion piece 201b to reset. At this time, the follower 201a is no longer subjected to force, and the elastic piece 204 on the follower 201a releases the elastic force, driving the follower 201a to reset, and re-enter the limiting hole 103a to complete the reset.
[0040] In summary, this solution can simply complete the disassembly of the mechanical arm connected to the connecting member 102 through the elastic member 204 and the unlocking member 205, and reset it for the next installation, which is simpler and more convenient to use.
[0041] Example 3
[0042] Reference Figure 1 to Figure 5 , which is the third embodiment of the utility model, provides a surround-type robot arm column installation device, which includes the locking structure in embodiments 1 and 2, and also includes a fixing assembly 300 composed of a fixing block 301 and a rotating groove 302.
[0043] Specifically, the fixing block 301 is disposed on the fixing body 103 and fixedly connected to the column by bolts, the rotation groove 302 is opened on the fixing block 301, the mounting body 101 is disposed in the rotation groove 302, and the limiting hole 103a is correspondingly opened in the rotation groove 302.
[0044] When in use, the fixing block 301 fixedly connected to the fixing body 103 is installed on the column by bolts, and a rotation groove 302 is opened on the fixing body 103 so that the fixing body 101 can rotate freely in the rotation groove 302 .
[0045] In summary, this solution installs the fixed body 103 on the column through the fixed block 301, and changes the shape of the fixed body so that the mounting body 101 can move in a circle around the fixed body 103, thereby making the working area of the robot arm 360° and covering a wider working area.
[0046] Additionally, in order to provide a concise description of example embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.
[0047] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.
[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
