Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
As first aspect of the present invention, provide a kind of equilibrium arm.Please refer to Fig. 3-9, this equilibrium arm comprises: arm body 10, arm body 10 is provided with counterbalanced weight installing port 50; For adjusting the occlusion part 40 of the size of counterbalanced weight installing port 50, occlusion part 40 is arranged on arm body 10 and also can moves by opposing arms body 10, especially, and being opened or closed by the motion of occlusion part 40 at least partially in counterbalanced weight installing port 50.
When installation counterbalanced weight, occlusion part 40 can be moved to the position that counterbalanced weight installing port 50 is opened, thus expose counterbalanced weight installing port 50.When only needing to install less counterbalanced weight (when such as galianconism is long), occlusion part 40 can be made to move to cover the position of (namely closing) counterbalanced weight installing port 50.Certainly, occlusion part 40 can move to the part only sheltering from counterbalanced weight installing port 50, and makes its another part be in the state opened, to install counterbalanced weight 20 block by block.Like this, along with the installation of counterbalanced weight, counterbalanced weight installing port 50 is opened gradually, and further, the shift position of occlusion part 40 can be determined according to the size of the balance block of required installation.
Therefore, the present invention is not when needing install counterbalanced weight or do not need to install all counterbalanceds weight, the open section of the counterbalanced weight installing port 50 on arm body 10 can be covered at any time by occlusion part 40, thus eliminate potential safety hazard, improve safety, in addition, do not need to arrange erecting stage in the both sides of arm body 10, thus reduce cost yet.When installing counterbalanced weight, only needing a people to stand on occlusion part and can complete, having the advantages that structure is simple, easy to operate.
In one embodiment, occlusion part 40 is slidably arranged on arm body 10 along the bearing of trend of arm body 10.Like this, only need to adjust the position of occlusion part 40 on the bearing of trend of arm body 10, just can adjust the size of counterbalanced weight installing port 50.In another unshowned embodiment, occlusion part 40 has foldable structure (such as corrugated foldable structure) or telescopic structure (such as the telescopic structure of similar Antenna Type), by foldable structure or telescopic structure, occlusion part 40 is folded or shrinks, thus can adjust the size of counterbalanced weight installing port.
Preferably, equilibrium arm also comprises fixed railing 12, and fixed railing 12 is connected with arm body 10.Preferably, equilibrium arm also comprises movable railing units 70, and movable railing units 70 is arranged on occlusion part 40, and can move with the motion of occlusion part 40, thus make the zone of protection that formed between fixed railing 12 and movable railing units 70 along with occlusion part 40 movement, thus enhance safety when installing counterbalanced weight.Preferably, the fixed platform 11 that arm body 10 comprises framework 14 and is arranged on framework 14, occlusion part 40 is slidably disposed on the top of fixed platform 11.
Please refer to shown in Fig. 5,8-9, occlusion part 40 comprises body 41 and is arranged on the sliding part 42 of body 41 both sides, and arm body 10 comprises the guide part 14a that the bearing of trend along arm body 10 is arranged, and sliding part 42 and guide part 14a are cooperatively arranged.As shown in Figure 5, body 41 is supported on guide part 14a by sliding part 42, and can slide along guide part 14a.
