[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 3The utility model provides an embodiment: a suspended power-assisting arm, including a base 1, a support column 2 is passed through and fixedly connected to the inner wall at the top of the base 1, and four sets of moving wheels 4 are arranged at the bottom end of the outer wall of the base 1. By providing four sets of moving wheels 4, the whole body can be conveniently moved, so that the workpiece lifted by the power-assisting arm mechanism 3 can be moved, which is the prior art. The top of the outer wall of the support column 2 is provided with a power-assisting arm mechanism 3. The power-assisting arm mechanism 3 is the prior art, which has multiple joints and adjustable mechanisms, allowing the user to adjust the height, angle and position according to needs. This flexibility enables the power-assisting arm mechanism 3 to adapt to different working scenes and operating requirements.

[0033] Reference Figure 2-Figure 3 The inner wall of the base 1 is provided with an extension component 5, which includes a swivel 51, which is rotatably connected to the outer wall of the support column 2, and the inner wall of the swivel 51 is provided with a cavity, which fits the outer diameter of the bottom end of the support column 2, so that the swivel 51 can be rotated on the inner wall of the bottom end of the support column 2, and the swivel 51 passes through and is rotatably connected to the inner wall of the top end of the base 1, and the bottom end of the outer wall of the swivel 51 is fixedly connected with a guide plate 52, which is rotatably connected to the outer wall of the bottom end of the support column 2, and the center of the guide plate 52 is also provided with a cavity which fits the outer diameter of the support column 2, and through the swivel The rotation of 51 can drive the guide plate 52 to rotate synchronously. The inner wall of the swivel ring 51 is elastically connected with the plug block 54 through the limit spring 53. The plug block 54 penetrates and is slidably connected to the inner wall at the top of the swivel ring 51. The outer wall at the bottom end of the support column 2 is provided with a circle of through holes. The bottom end of the outer wall of the plug block 54 is plugged into the inner wall of the through hole. The plugging between the two can fix the multiple positions of the guide plate 52 after the swivel ring 51 drives the guide plate 52 to rotate, thereby fixing the position of the positioning rod 56 and the moving block 55 that move on the inner wall of the guide plate 52 after the guide plate 52 rotates.

[0034] Reference Figure 2-Figure 3One end of the limit spring 53 is fixedly connected to the surface of the plug block 54, and the other end of the limit spring 53 is fixedly connected to the inner wall of the swivel 51. The function of the limit spring 53 is to automatically reset the position of the plug block 54 after it is pulled outward. The surface of the guide plate 52 is provided with four groups of arc grooves, and the inner wall of the arc groove of the guide plate 52 is slidably connected with a positioning rod 56. By providing an arc groove on the surface of the guide plate 52, the guide plate 52 will drive the positioning rod 56 to move in its arc groove when it rotates, thereby driving multiple groups of moving blocks 55 to move synchronously to move outward or retract. The surface of the top of the base 1 is provided with four groups of guide grooves, and the positioning rod 56 penetrates and is slidably connected to the guide groove on the top surface of the base 1. The inner wall is provided with a guide groove on the surface of the base 1, so that when the positioning rod 56 moves on the inner wall of the arc groove of the guide plate 52, it will not move synchronously with the rotation of the arc groove, so that it can only move forward and backward, thereby pushing the moving block 55 to move outward, and the bottom end of the outer wall of the positioning rod 56 is fixedly connected with the moving block 55, and four groups of empty grooves are provided on the inner wall at the bottom end of the base 1. The moving block 55 is slidably connected to the inner wall of the empty groove at the bottom end of the base 1. By providing an empty groove at the bottom end of the base 1, the tail end of the moving block 55 can be stored in the inside of the base 1 when not in use, so as to avoid excessive expansion affecting the daily movement of lifting the workpiece through the power-assisted arm mechanism 3, and a support assembly 6 is provided at the end of the moving block 55 away from the positioning rod 56.

[0035] Reference Figure 3-Figure 4 The supporting assembly 6 includes a wedge block 62, which is elastically connected to the inner wall of the moving block 55 by a return spring 61. One end of the return spring 61 is fixedly connected to the surface of the wedge block 62, and the other end of the return spring 61 is fixedly connected to the inner wall of the moving block 55. The function of the return spring 61 is that when the inclined surface of the wedge block 62 is squeezed by the inner wall of the slot of the moving rod 63 and moves outward, the position of the wedge block 62 after moving can be automatically reset. The wedge block 62 passes through and is slidably connected to the inner wall of the moving block 55. The surface of the moving rod 63 is provided with a plurality of groups of slots, and the wedge block 62 is engaged with the inner wall of the slot. The engagement between the two fixes the moving rod 63 at multiple positions of the moving inner wall of the moving block 55, and after the two are unplugged, the moving rod 63 can be quickly moved to allow the contact block 66 to quickly fit the ground, without the need to rotate the threaded rod 65 multiple times to lower the contact block 66.

[0036] Reference Figure 4The inner wall of the moving block 55 passes through and is slidably connected with a moving rod 63. The inner wall of the moving block 55 is provided with guide blocks that fit on both sides of the moving rod 63, so that the moving rod 63 can only move up and down on the inner wall of the moving block 55, and cannot rotate itself, and supports the bottom connecting block 64, so as to prevent the threaded rod 65 from driving the connecting block 64 to rotate synchronously with it when it rotates. The bottom end of the moving rod 63 is fixedly connected with the connecting block 64, and the right inner wall of the connecting block 64 passes through and is threadedly connected with the threaded rod 65. The bottom end of the outer wall of the threaded rod 65 is fixedly connected with the contact block 66, and the inner wall of the connecting block 64 is provided with an internal thread. The rotation of the threaded rod 65 can make the contact block 66 descend to contact the ground, so as to perform fine adjustment to make the contact block 66 close to the ground, thereby increasing the contact area between the overall device and the ground and making it more stable.

[0037] Working principle: The four sets of moving wheels 4 at the bottom end of the outer wall of the base 1 facilitate overall movement. The power-assisting arm mechanism 3 is located at the top end of the outer wall of the support column 2, and the height, angle and position can be adjusted as needed to adapt to different working scenes and operating requirements.

[0038] In the extension assembly 5 of the inner wall of the base 1, the swivel 51 is rotatably connected to the outer wall of the support column 2. When support with the ground is required, the swivel 51 can be rotated to drive the guide plate 52 to rotate synchronously with it. The positioning rod 56 is slidably connected in the arc groove on the surface of the guide plate 52. The rotation of the guide plate 52 drives the positioning rod 56 to move along the arc groove. The positioning rod 56 can only move forward and backward in the guide groove on the top surface of the base 1, thereby pushing the moving block 55 to move outward or shrink, so that the moving block 55 is expanded outward, which is convenient for the use of the support assembly 6. When not in use, the tail end of the moving block 55 is stored in the base 1.

[0039] After the moving block 55 is unfolded, the moving rod 63 can be directly pressed downward to move it down, so that the inner wall of the slot of the moving rod 63 contacts the inclined surface of the wedge block 62, thereby squeezing the wedge block 62 outward and allowing the return spring 61 to be elastically compressed until it reaches the next set of slots, where it will be elastically acted upon by the return spring 61 to restore it to its initial position to engage with the slot of the current position of the moving rod 63. At the same time, the moving rod 63 is restricted by the guide block on the inner wall of the moving block 55 and can only move up and down. The connecting block 64 at its bottom end is threadedly connected to the threaded rod 65, and the contact block 66 is lowered to contact the ground through the rotation of the threaded rod 65 for fine adjustment so that the contact block 66 is close to the ground.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
