In and be bolted in the screw 328 of mounting seat 32, thus, when rotating this precompressed and adjusting screw 36
Can drive installation seat 32 be relatively fixed frame 20 produce move forward and backward, in order to adjust flexible member 33
Precompression.
It should be added that at this, the mounting groove 326 of mounting seat 32, flexible member 33,
As long as and the number of end cap 34 actually at least one, but with two be in use
Optimum selection.
Please refer to Fig. 2, Fig. 3 and Fig. 5, brake 40 has central shaft 41, shell
42, and a brake unit 43.The articulated section of fixed mount 20 is fixed at the two ends of central shaft 41
The bottom of 22；Shell 42 is sheathed on central shaft 41 and can be relatively fixed for axle center with central shaft 41
Frame 20 pivots；Brake unit 43 has an armature 44, and armature 44 has yoke 45, line
Circle 46, and a permanent magnet 47, yoke 45 is fixed on shell 42 and is sheathed on central shaft 41,
Coil 46 and permanent magnet 47 are respectively arranged in yoke 45, additionally, brake unit 43 also has
One leaf spring 48 and an armature plate 49, the sheathed central shaft 41 that is fixed on of leaf spring 48, armature plate 49 overlaps
It is located at central shaft 41 and is fixed on the leaf spring 48 one side towards armature 44.
Please refer to Fig. 2 and Fig. 4, support bar 50 has one first rod member 51, parallel
Second rod member 52 of one rod member 51, and one between first, second rod member 51,52
Three rod members 53.The rear end of the first rod member 51 pivot by one first pivot 54 pivot joint fixed mount 20
Connecing the top in portion 22, one second pivot 55 pivot joint the 3rd rod member is passed through in the front end of the first rod member 51
The top of 53, the rear end of the second rod member 52 connects the outer peripheral face of the shell 42 of brake 40, makes
Obtain shell 42 meeting and the second rod member 52 synchronous axial system, the front end of the second rod member 52 of brake 40
Bottom by one the 3rd pivot 56 pivot joint the 3rd rod member 53.Additionally, the top of the 3rd rod member 53
End laterally extends an object fixed part 532 outward, and object fixed part 532 is covered with a switch base
57, the end face of switch base 57 is provided with a control switch 70, controls switch 70 electric connection armature
The coil 46 of 44, in order to power-off and the energising of control coil 46.
Please refer to Fig. 2 and Fig. 4, flexible member 60 at this as a example by cable wire.When mounted,
This two flexible member 60 is set around the outer peripheral face of the shell 42 of brake 40, and, this two is scratched
One end of property element 60 is fixed on a fixed block 62 jointly, and fixed block 62 is fixed on brake 40
The outer peripheral face of shell 42, the other end of this two flexible member 60 pile warp respectively is a set of is located at first
The idle pulley 64 of pivot 54, passes the mounting groove 326 of mounting seat 32 the most respectively and is fixed on end
Lid 34.
Before moving object to be started, first pressing controls switch 70 and makes the coil of armature 44
46 present "on" position, in the case, and reverse magnetic force meeting and permanent magnetic produced by coil 46
The magnetic force of ferrum 47 cancels each other, and the captivation between yoke 45 and armature plate 49 also can disappear therewith
Losing, brake 40 now is positioned at an off-position P1, as it is shown in figure 5, then can pass through
The pivot of support bar 50 and start object is carried, in handling process, flexible member 60
Coupled end cap 34 can be pulled by the rotation of the shell 42 of brake 40, then hold
Lid 34 can start compression elastic element 33, makes flexible member 33 provide the start of support bar 50
The stable effect supported.Once support bar 50, object is transported to suitable height and position, then
Secondary pressing controls switch 70 and controls the coil 46 of armature 44 and present off-position, in this situation
Under, armature plate 49 can be held by yoke 45 through the magnetic force of permanent magnet 47, makes brake 40
Switch to a brake position P2, as shown in FIG. 6 and 7, consequently, it is possible to outside brake 40
Shell 42 will be unable to be rotated further, support bar 50 just can from brake 40 obtain brake effect and complete
The location of elephant in pairs.
In sum, the present invention can brake type support arm 10 to utilize flexible member 33 to produce permissible
The elastic acting force of opposing gravity, makes support bar 50 stably can carry object, and
And can utilize according to actual needs in handling process control switch 70 to start brake 40,
Make brake 40 to support bar 50 offer brake effect by object lock at estimating position, to reach
Purpose to lifting operation convenience.
