[0029] Numerous details are explored in the following description to provide a more thorough explanation of embodiments of the present disclosure. However, it will be apparent to those skilled in the art that embodiments of the present disclosure may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present disclosure.

[0030] Please see Figure 1 This utility model provides a locking mechanism, including a fixed base, a horizontal swing arm assembly 3, a vertical swing arm assembly 4, and a locking assembly 5. The fixed base includes a base 1 and a column 2. The base 1 has a plane that can be stably and fixedly connected to the ground or a workbench. The column 2 is vertically arranged and fixedly connected to the base 1. The column 2 is provided with an installation area for installing an electrical box and control panel. The horizontal swing arm assembly 3 is located on the top of the column 2. The vertical swing arm assembly 4 is connected to the output end of the horizontal swing arm assembly 3. The locking assembly 5 is connected to the output end of the vertical swing arm assembly 4. 3 is used to support the vertical swing arm assembly 4 and the locking assembly 5 for lateral movement. The vertical swing arm assembly 4 is used to support the locking assembly 5 for vertical movement. The vertical swing arm assembly 4 has an adjusting member 6 for adjusting the center of gravity of the locking assembly 5. In this embodiment, the adjusting member 6 is an adjusting cylinder. When the operator operates the locking assembly 5 to move the vertical swing arm assembly 4 up and down, the adjusting cylinder is used to balance the position. When the locking assembly 5 moves upward, the adjusting cylinder retracts; when the locking assembly 5 moves downward, the adjusting cylinder extends. Dynamic balance is achieved in this way, thereby reducing the operator's workload.

[0031] Specifically, in an optional embodiment of this application, the vertical swing arm assembly 4 further includes a swing arm 41, a first mounting bracket 42, and a second mounting bracket 43. Both the first mounting bracket 42 and the second mounting bracket 43 are vertically arranged. The first mounting bracket 42 is rotatably connected to the horizontal swing arm assembly 3. Both the first mounting bracket 42 and the second mounting bracket 43 have mounting grooves 44 for mounting the swing arm 41, and the two mounting grooves 44 are respectively located on the opposite surfaces of the first mounting bracket 42 and the second mounting bracket 43. Both mounting grooves 44 are vertically arranged. One end of the swing arm 41 is hinged to the inner wall of the mounting groove 44 of the first mounting bracket 42, and the other end of the swing arm 41 is hinged to the inner wall of the mounting groove 44 of the second mounting bracket 43. The swing arm 41 can swing up and down around the first mounting bracket 42. The adjusting member 6 is disposed on the swing arm 41.

[0032] Please see Figure 2Specifically, in an optional embodiment of this application, the swing arm 41 includes an upper frame 411 and a lower frame 412, which are arranged in parallel. Both ends of the upper frame 411 and the lower frame 412 are respectively hinged in the mounting groove 44 of the first mounting frame 42 and the mounting groove 44 of the second mounting frame 43. There is friction between the upper frame 411 and the first mounting frame 42 and the second mounting frame 43, and there is also friction between the lower frame 412 and the first mounting frame 42 and the second mounting frame 43. The friction is greater than the weight of the upper frame 411 and the lower frame 412 themselves. Without the application of external force, the upper frame 411 and the lower frame 412 remain stationary. A receiving groove for accommodating the adjusting member 6 is formed between the upper frame 411 and the lower frame 412. The adjusting member 6 is disposed in the receiving groove and is adjusted as the swing arm 41 swings up and down to achieve dynamic balance.

[0033] Specifically, in one optional embodiment of this application, the receiving groove is provided with a mounting base 413 and an adjusting base 414. The mounting base 413 is connected to the upper frame 411, and the adjusting base 414 is connected to the lower frame 412. One end of the adjusting member 6 is hinged to the mounting base 413 through a first connecting member, and the other end of the adjusting member 6 is hinged to the adjusting base 414 through a second connecting member. The mounting base 413 and the adjusting base 414 are spaced apart in the horizontal direction. In this embodiment, the adjusting member 6 is arranged parallel to the upper frame 411 and the lower frame 412. When the swing arm 41 swings upward, the horizontal distance between the mounting base 413 and the adjusting base 414 decreases, and the adjusting member 6 retracts. When the swing arm 41 swings downward, the horizontal distance between the mounting base 413 and the adjusting base 414 increases, and the adjusting member 6 extends, thereby achieving dynamic balance adjustment.

[0034] Specifically, in an optional embodiment of this application, the end of the mounting base 413 away from the upper frame 411 is inclined toward the adjusting base 414, and the end of the adjusting base 414 away from the lower frame 412 is inclined toward the mounting base 413.

[0035] Specifically, in an optional embodiment of this application, the lateral swing arm assembly 3 includes a first rotating assembly 31, a first cantilever 32, and a second rotating assembly 33. The bottom of the first rotating assembly 31 is connected to the top of the column 2. One end of the first cantilever 32 is rotatably connected to the first rotating assembly 31 and rotates around the first rotating assembly 31. The other end of the first cantilever 32 is connected to the top of the second rotating assembly 33. The first rotating assembly 31 and the second rotating assembly 33 have the same structure. The first rotating assembly 31 includes a mounting platform and a rotating disk. The mounting platform of the first rotating assembly 31 is used to connect to the top of the column 2. The mounting platform of the second rotating assembly 33 is used to connect to the bottom of the second end of the first cantilever 32. The rotating disk is connected to the mounting platform and can rotate. The two-stage lateral swing makes adjustment more convenient.

[0036] Specifically, in an optional embodiment of this application, the locking assembly 5 includes a locking member 51, a connecting rod 52, and a third rotating assembly 53. The third rotating assembly 53 is fixedly connected to the second mounting bracket 43. The locking member 51 is connected to the third rotating assembly 53 through the connecting rod 52. The locking member 51 can rotate around the third rotating assembly 53 through the connecting member for fine position adjustment.

[0037] Specifically, in an optional embodiment of this application, the first rotating assembly 31, the second rotating assembly 33, and the third rotating assembly 53 are all provided with locking components 7; the locking component 7 has an upper locking member, a lower locking member, and a connecting part for fixing. The upper locking member and the lower locking member are both connected to the connecting part, and a locking groove is formed between the upper locking member and the lower locking member. The distance between the upper locking member 51 and the lower locking member can be adjusted, thereby adjusting the size of the locking groove. When the locking member 51 moves to the position and needs to be locked, the upper locking member and the locking member are controlled to reduce the locking groove, thereby locking the first rotating assembly 31, the second rotating assembly 33, and the third rotating assembly 53 to prevent continued swinging from affecting the locking.

[0038] Specifically, in one optional embodiment of this application, a control valve is provided on the locking component 51. The control valve is electrically connected to the plurality of locking components 7. When the component moves into position and needs to be locked, the operator locks the locking components 7 through the control valve at the locking component 51.

[0039] Specifically, in an optional embodiment of this application, the locking member 51 of the control valve is further provided with a hand-held member 8. One end of the hand-held member 8 is connected to the locking member 51, and the other end of the hand-held member 8 is a hand-held part. The operator moves the position of the locking member 51 through the hand-held part.

[0040] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
