Embodiment
The present invention is described further with reference to the accompanying drawings and examples.
Embodiment one：It is only one of embodiment of the present invention as shown in accompanying drawing 1 to 5, a kind of monoblock type handrail strap tensioning dress
Put, including fixed part 1, move portion 2 and the truss 3 for installing the fixed part 1, the fixed part 1 include fixed plate 11, used
Carrying roller 12 and the chute 13 slided for the move portion 2 are oriented in what guiding handrail 5 was driven, the move portion 2 includes moving
Dynamic plate 21 and the pressure roll 22 being arranged on the movable plate 21, the fixed part 1 are connected by adjustment portion 4 and the move portion 2
Connect, the adjustment portion 4 includes connecting screw 41, the spring 42 being connected with the connecting screw 41 and is arranged at the connecting screw
The regulating bolt 43 of 41 ends.
A kind of monoblock type handrail strap tensioning device of the present invention, installed in the top of truss 3, bottom, rake and it can appoint
Meaning position, and be that slidably can adjust between fixed part 1 and move portion 2.
Move portion 2 can be slided on the chute 13 of fixed part 1.
Move portion 2 adjusts position of the move portion 2 on fixed part 1 by adjustment portion 4.
So move portion 2 and fixed part 1 is both overall and can mutual cooperation work.
It is to the tensioner process of handrail 5 specifically：
Bending radius arrangement when being set on fixed part 1 and be oriented to carrying roller 12, and being oriented to carrying roller 12 according to 5 tensioner of handrail；
Pressure roll 22 is provided with move portion 2, and bending radius arrangement when pressure roll 22 is according to 5 tensioner of handrail；
When handrail 5, which loosens, needs to carry out tensioner, by adjusting the regulating bolt 43 of adjustment portion 4, pass through the band of connecting screw 41
Dynamic movable plate 21 moves down, and pressure roll 22 pushes, so as to reach the purpose of tensioner handrail.
As shown in Figure 1, the structural representation before being tensioner handrail 5；
As shown in Figure 2, it is the structural representation after tensioner handrail 5.
The tensioner of handrail 5 relies primarily on the guiding for being oriented to carrying roller 12, and adjustment portion 4 adjusts pressure roll 22 to handrail
5 pressure.
In said apparatus, the carrying roller 12 that is oriented to is two groups of carrying rollers being symmetrically set.
Two groups of carrying rollers can effectively guide the transmission of handrail 5, and bending radius arrangement during according to 5 tensioner of handrail,
The transmission of handrail 5 is more smooth, will not be stuck.
In said apparatus, the quantity at least two for being oriented to carrying roller 12.
In fact, the quantity for being oriented to carrying roller 12 can be 2,4,6 etc..Just there are 6 in accompanying drawing 1, be only optimal
One embodiment of guiding.
Embodiment two, a kind of monoblock type handrail strap tensioning device of the present invention, the specific tensioner process that adjusts rely on adjustment portion complete
Into.
As shown in Figure 5, it is only one of embodiment of the present invention, adjustment portion 4 is mainly that the connection of connecting screw 41 is solid
Determine portion 1 and move portion 2.
In said apparatus, the adjustment portion 4 also includes the spacing beam 44 being arranged in the move portion 2 and is arranged at described
Regulation beam 45 on fixed part 1.
The top of connecting screw 41 is connected beam 44, the bottom connection regulating bolt 43 of connecting screw 41, connecting screw
41 are connected by spring 42 with spacing beam 45.
The mobile conduction of connecting screw 41 to move portion 2 is caused the movement of move portion 2, so as to reach by so fixed beam 44
To the purpose of tensioner.
Spacing beam 45 limits the maximum moving range of connecting screw 41, and provides support to the bounce of spring 42.
In said apparatus, the screw passed through for connecting screw 41 is provided with the spacing beam 44 and regulation beam 45.
Connecting screw 41 is at least part of to be arranged in the spacing beam 44 and regulation beam 45.Screw also allows for adjusting spiral shell

In said apparatus, the spacing beam 44 is provided with limited bolt 46 with the junction of connecting screw 41.
So that the top of connecting screw 41 is stably connected with fixed beam 44, the pressure of regulation is accurately transmitted so that handrail 5
Tensioner process is more convenient, accurate.
In said apparatus, screw thread 47 is provided with the connecting screw 41.
The screw thread 47 is external screw thread.
The connecting screw 41 is at least part of in the spring 42.
It is arranged to external screw thread 47 and is easy for connecting screw 41 to carry out spiral shell in screw and enter spiral shell to go out, and facilitates regulating bolt 43 to even
Connect the conduction of the power of the regulation of screw rod 41.
It is noted herein that can be in swelling device of the present invention just at work, that is, handrail 5 transmits
During, the position of move portion 2 is adjusted.Need only to that regulating bolt 43 is adjusted and can complete tensioner mistake
Journey.
Embodiment three, a kind of monoblock type handrail strap tensioning device of the present invention, in order to further increase stability and security,
Also following design.
It is only one of embodiment of the present invention as shown in accompanying drawing 1 to 5.
In said apparatus, the both ends of fixed plate 11 are connected by vertical columns 14 with the truss 3.
Fixed part 1 is fixed by vertical columns 14, and the present apparatus can be fixed in the optional position of truss 3.
In said apparatus, the fixing bolt 15 for fixing the fixed plate 11 is provided with the fixed plate 11.
Fixing bolt 15 carries out the fixation to fixed plate 11 for auxiliary vertical columns 14 so that fixed part 1 is in tensioner process
In will not shake and obscission.
In said apparatus, the connecting pole for connecting the movable plate 21 and fixed plate 11 is provided with the movable plate 21
23。
Also for the tensioner stability of fixed move portion 2, phenomenon will not be fallen off.
In said apparatus, the quantity of the chute 13 is equal to the quantity of the pressure roll 22 and the quantity of the connecting pole 23
Sum.
In fact, it is the chute of the jack-post slip for pressure roll 22 that chute 13, which is divided to for two classes, one kind, another kind of is to be used for
The chute that the jack-post of connecting pole 23 slides.
The quantity of so chute 13 is the quantity sum of connecting pole 23 and pressure roll 22.
