The present invention discloses a kind of double structure stretcher, including the belt between driving wheel, driven wheel and driving wheel and driven wheel；And a fixed vertical sleeve is also equipped between the driving wheel and driven wheel, line between the vertical sleeve and driving wheel and driven wheel is perpendicular, and the upper and lower side of the vertical sleeve is respectively equipped with a loop bar, the tail end for the loop bar being arranged in vertical sleeve is respectively equipped with a limiting plate.The present apparatus is during belt transmission, loose situation occurs in belt can direct tightening belt, and the oblique sleeve in the present apparatus is the angle that can change oblique sleeve by hinge assembly, the angle of four oblique sleeves can be identical, can also difference be adjusted to according to tensioning required angle, increase it and be tensioned quality and using effect.
Description
Technical field
The present invention relates to drive apparatus, specifically a kind of double structure stretcher.
Background technology
In order to keep the tensioning degree of driving belt in transmission device, stretcher can be mostly designed together, in the prior art
Stretcher be utilized in driving wheel more either one stretcher of installation tense driving wheel or driven wheel at driven wheel, make belt
Tensioning is kept, but when actual use, needs additionally to connect subsequent equipment by transmission by driving wheel and driven wheel
Power is transferred in follow-up equipment, therefore the bad change in the position of driving wheel and driven wheel or can only compare changing for thin tail sheep
Become the tensioning to ensure belt pulley, tensioning degree and using effect are undesirable.
Invention content
The purpose of the present invention is in view of the deficienciess of the prior art, providing a kind of double structure stretcher.
Technical solution：It is of the present invention solve the problems, such as used by technical solution be：A kind of double structure stretcher, including actively
Belt between wheel, driven wheel and driving wheel and driven wheel；Fixation peace is provided between the driving wheel and driven wheel
The vertical upright bar of dress, the two of the perpendicular and described vertical upright bar of line between the vertical upright bar and driving wheel and driven wheel
A end is respectively equipped with transition wheel, and the belt is then bypassed from transition wheel, and the upper and lower side two of the vertical upright bar
Side is also separately installed with an oblique sleeve, the oblique sleeve up and down it is each it is angularly disposed there are two, oblique sleeve is provided with altogether
Four, and four oblique sleeves and vertical upright bar are in the same plane；The bottom of the oblique sleeve is also equipped with being tensioned
Spring, and oblique loop bar is also equipped in oblique sleeve, the oblique loop bar pushes down tensioning spring, and the oblique set
The end of bar is also equipped with tensioning wheel, and the belt is then bypassed from tensioning wheel and transition wheel.
Preferably, the wheel end of the driving wheel is fixedly mounted by fixing device；And the wheel shaft of the driven wheel
Both ends are then equipped with spring tensioning means.
Preferably, the upper and lower side of the vertical upright bar is also respectively equipped with a hinge assembly, and the oblique sleeve
It is then mounted on handing-over component.
Preferably, in order to which oblique sleeve is made to have appropriate tensioning angle, the oblique sleeve passes through hinged group
The adjustable angle of part is set as 30-60 °.
Advantageous effect：Compared with traditional prior art, the present invention has the following advantages：Stretcher in the present apparatus is first
The belt for being driven driven wheel by the transition wheel for setting a vertical upright bar upper and lower side jacks up, the mistake above and below vertical upright bar
Ferry boat can reduce the pressure of tensioning wheel as the basic point supported up and down；The upper and lower side of vertical upright bar is installed angularly disposed again
Oblique sleeve, oblique sleeve inner installs oblique loop bar by tensioning spring, and finally installation can jack up belt to oblique loop bar
Tensioning wheel, tensioning wheel under the action of the tensioning spring of strength can complete tightening belt, during belt transmission, belt goes out
Now loose situation can direct tightening belt, and the oblique sleeve in the present apparatus is can to change oblique set by hinge assembly
The angle of cylinder, the angle of four oblique sleeves can be identical, can also be adjusted to difference according to tensioning required angle, increase it
Tight quality and using effect.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Specific embodiment
In the following with reference to the drawings and specific embodiments, the present invention is furture elucidated, and the present embodiment is with technical solution of the present invention
Premised under implemented, it should be understood that these embodiments are only illustrative of the invention and is not intended to limit the scope of the invention.
As shown in Figure 1, a kind of double structure stretcher, including driving wheel 1, driven wheel 2 and driving wheel 1 and driven wheel 2 it
Between belt 3；The vertical upright bar 4 of a fixed installation is provided between the driving wheel 1 and driven wheel 2, the vertical upright bar 4 with
Line between driving wheel 1 and driven wheel 2 is perpendicular, and two ends of the vertical upright bar 4 are respectively equipped with transition wheel 5,
And the belt 3 is then bypassed from transition wheel 5, and the upper and lower side both sides of the vertical upright bar 4 are also separately installed with one tiltedly
To sleeve 6, the oblique sleeve about 6 it is each it is angularly disposed there are two, oblique sleeve 6 is altogether there are four settings, and four are oblique
Sleeve 6 and vertical upright bar 4 are in the same plane；The bottom of the oblique sleeve 6 is also equipped with tensioning spring 7, and tiltedly
Oblique loop bar 8 is also equipped with into sleeve 6, the oblique loop bar 8 pushes down tensioning spring 7, and the end of the oblique loop bar 8
Portion is also equipped with tensioning wheel 9, and the belt 3 is then bypassed from tensioning wheel 9 and transition wheel 5.
The wheel end of the driving wheel 1 is fixedly mounted by fixing device；And the wheel shaft both ends of the driven wheel 2 are then pacified
Equipped with spring tensioning means 10；The upper and lower side of the vertical upright bar 4 is also respectively equipped with a hinge assembly 11, and described oblique
Sleeve 6 is then mounted on handing-over component 11；The oblique sleeve 6 is set as 30- by 11 adjustable angle of hinge assembly
60°。
The belt top that driven wheel is driven by the stretcher in the present apparatus by the way that a vertical upright bar is set to be used for first
It rises, vertical upright bar can reduce the pressure of tensioning wheel as the basic point supported up and down；The upper and lower side of vertical upright bar is installed tiltedly again
To the oblique sleeve of setting, oblique sleeve inner installs oblique loop bar by tensioning spring, and finally installation can jack up oblique loop bar
