Embodiment
Technical scheme is clearly and completely described with reference to Figure of description.
A kind of scalable handrail applied to human body three-dimensional scanning device as shown in Figures 1 to 5, including handrail upper boom
1st, handrail lower beam 2, electromagnetic brake 3 and braking slide 5；Handrail lower beam 2 is internally provided with cavity, and braking slide 5 is fixed at
In the cavity of handrail lower beam 2；Handrail upper boom 1 and electromagnetic brake 3 are arranged in the cavity of handrail lower beam 2, and can be in cavity
Slide；Electromagnetic brake 3 includes electromagnet 4, detent housing 8, braking thimble 6 and braking thimble sliding block 7；Detent housing 8 is fixed
1 bottom of handrail upper boom or other positions are arranged on, and are provided with brake hole 10；Electromagnet 4 and 7 company of fixation of braking thimble sliding block
Connect, slided in detent housing 8；Braking thimble sliding block 7 is provided with inclined slideway 9, and one end of braking thimble 6 is hinged on system
In the slideway 9 of dynamic thimble sliding block 7, and slided in slideway 9, the other end coordinates through brake hole 10 and braking slide 5.
Braking slide 5 is fixed in the cavity of handrail lower beam 2, specific to be fixed at for 5 lower end of braking slide
On handrail lower beam 2, upper end coordinates with electromagnetic brake 3, or 5 entirety of braking slide is fixed on handrail lower beam 2, handrail
Upper boom 1 is provided with the track that braking slide 5 slips over.
The slip of braking thimble 6 can be realized by the control to electromagnet 4, realizes that braking thimble 6 is produced with braking slide 5
It is raw run through, engage, one or more cooperations in the fit system such as tight fit, make the modes of its remains stationary state, in realization
The position that handrail reaches desired height is fixed.The flexible of braking thimble 6 makes it coordinate with braking slide 5, to reach system
Dynamic effect, is specially after electromagnet 4 is powered, and electromagnet 4, which moves up and down, produces thrust, the breaking top being fixedly connected with electromagnet 4
Pin sliding block 7 moves up and down at the same time, because the one end for braking thimble 6 passes through brake hole 10 all the time, is cut with scissors with braking 7 slideway 9 of thimble sliding block
The braking thimble 6 connect moves along a straight line in brake hole 10, realizes the cooperation with braking slide 5.
When it is through cooperation to brake thimble 6 with braking slide 5, brakes and multiple through holes are provided with slide 5, brake thimble
6 realize braking thimble 6 with braking the cooperation of slide 5 through through hole.
When it is to engage cooperation to brake thimble 6 with braking slide 5, the top of braking thimble 6 is equipped with rack, brakes slide 5
On be provided with multiple racks, the cooperation realized braking thimble 6 and brake slide 5 is engaged by rack and rack.
When it is tight fit to brake thimble 6 with braking slide 5, the top of braking thimble 6 is equipped with elastic material, passes through elasticity
Material realizes braking thimble 6 with braking the cooperation of slide 5 frictional force for braking slide 5.
Electromagnet 4 is pull-type electromagnet, pushing-type electromagnet or sucked type electromagnet, and handrail upper boom 1 and handrail lower beam 2 are most
Two kinds can mutually wear the component of size, but be not limited to tubular part, solid parts, aluminium section bar etc..
By the control to electromagnet can realize braking thimble 6 slip, realize in an initial condition brake thimble 6 with
Braking slide 5 does not have any contact, realizes that handrail upper boom 1 can be slided up and down freely, control electricity after adjusting to desired height
Magnet 4 makes braking thimble 6 be that both generations run through fit system, handrail reaches required in realization to movement at braking slide 5
The position of height is fixed.After the completion of scanning, electromagnet 4 restPoses, so that braking thimble 6 also returns to initial shape
State, i.e., depart from, handrail upper boom 1 automatically returns to initial position with braking slide 5.
Following several occupation modes can be realized by control of the control circuit to electromagnet：
1. original state is non-brake state, to be regulated to enter braking to after formulating height, automatic extensive after to be used
Multiple non-brake state；
2. original state is on-position, when height to be regulated, enters non-brake state, enters braking after to be regulated
When state to next time adjusts height；
3. original state is on-position, when height to be regulated, enters non-brake state, enters braking after to be regulated
State, enters non-brake state after to be used, enters on-position after highly recovering to handrail to elemental height.
The present invention realizes that handrail stretches, fix etc. and to act, and realizes the people according to different heights by electromagnetic braking mode
Freely adjust handrail height.
