The not strict restriction of the shape of described support can be have certain-length tabular, bar-shaped etc., can adopt metal with certain intensity or composite etc. to process.
Described circular-arc-shaped exterior contour can be circular arc line or arc surface, mainly contacts with motor, motor plate or motor cabinet, is used to push motor, makes the motor mobile position.
Described bar hole is preferably long-round-shape.
As preferably, the end face of described locating column has screw, and described locking member is the positioning screwn that cooperates with this screw, and an end of positioning screwn has the pressure cap that is used to compress the bar shaped bore edges.Described pressure cap can be the flange with the positioning screwn integrative-structure, also can be the packing ring that is provided with separately.
The top of described locating column has the head shoulder structure (similar ledge structure) that matches with the bar hole edge; Head passes bar hole; And the described screw that cooperates with locking member is positioned at the end face of head; The width of shoulder makes the bottom of locating column can't pass bar hole greater than the width of bar hole.
Through the qualification of locking member and shoulder, make locating column can't deviate from bar hole, and when the locking member non-locking, can slide along bar hole.
In order further to guarantee the position of locating column, prevent locating column loosening or unnecessary backward motion in the device adjustment process with respect to bar hole.As preferably, through bearing the adjustment screw of arranging along the bar hole direction is installed on the described support, the end and the locating column contact matching of adjustment screw.The further position of locking and positioning post in bar hole after the adjustment screw is screwed.
As preferably, the head of described locating column has catch, the end of described adjustment screw and catch contact matching.
Because described follower generally has axle center hole, described locating column can insert hole, follower axle center, and this just requires described locating column external diameter to be slightly less than the internal diameter in hole, follower axle center.
After locating column inserts hole, follower axle center,, can make the outer wall of the circular-arc-shaped exterior contour contact motor of support through the slip of locating column along bar hole; Locking member is locked locating column with respect to bar hole; Pull handle, whole support is around the locating column rotational, makes the circular-arc-shaped exterior contour of support push the outer wall of motor gradually; Change the distance between motor and the follower, reach the purpose of adjustment belt tension then.Certainly before adjustment, require to unclamp the fixing bolt on the electrode plate.
As preferably, when the adjustment belt tension, the locating column center does not overlap with the center of circle of circular-arc-shaped exterior contour, if coincidence, even the rotational support body also could change the distance between motor and the follower.
It is easy to use that the utility model can be adjusted the device of belt tension, is convenient to operation, and easy to process, and cost is lower.Utilize simple support concept, can adjust the size of belt tension easily.

Embodiment
For the purpose, technological scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Fig. 1 and Fig. 2 show a kind of device of adjusting belt tension with and the structural representation of user mode.For the ease of explanation, only show the part relevant with the utility model.
A kind of device of adjusting belt tension comprises support 1, and support 1 is tabular, and support 1 is provided with slotted hole (long-round-shape).
Support 1 one ends are as handle; The other end has the circular-arc-shaped exterior contour that is used for pushing motor; The top that is provided with the locating column 4 that can slide along slotted hole in the slotted hole has the head shoulder structure that matches with the slotted hole edge; Head 12 passes slotted hole, and the width of shoulder 13 makes the bottom of locating column 4 can't pass slotted hole greater than the width of slotted hole.Head 12 end faces have screw 14, and positioning screwn 3 passes large washer 2 backs and cooperates with screw 14, and large washer 2 and shoulder 13 are clamped the slotted hole edge.、
Head 12 has catch 15, and end and catch 15 contact matching of the adjustment screw of arranging along the slotted hole direction 5 further guarantee the position of locating column 4 with respect to slotted hole, prevent that locating column 4 from becoming flexible or unnecessary backward motion in the device adjustment process.
During use, at first locating column 4 bottoms are penetrated the endoporus of follower 6, as the rotating center of whole regulating mechanism; Motor 9 is fixed on the motor plate 7, then with the inside of whole electric machine assembly at ball machine 11, is used for fixing each screw of motor plate 7 this moment and does not all lock, and makes motor plate 7 adjustable positions.
The screw-in depth of coarse adjustment adjustment screw 5, simultaneously with positioning screwn 3 lockings, the effect of adjustment screw 5 is restriction locating column 4 backward motions in the device adjustment process; The handle of holding support 1 rotates around locating column 4 then, and support 1 end this moment (arc profile) is tangent with motor plate 7; Because the point of contact can increase along with the rotation of support 1 to the distance of locating column 4 gradually, can drive motor 9 away from follower 6 by pushing motor plate 7, and then belt 8 is strained gradually; Support 1 can be fixed when support 1 and motor 9 are vertical, and this moment can locking motor plate 7 and four set screws 10 of ball machine 11.Suitably regulate the screw-in depth of adjustment screw 5, the position of adjustable whole locating column 4 in the slotted hole of support 1, and then can strengthen or reduce the tension force of belt 8, the position of locating column 4 will adjust screw 5 and fix when finding only tension force.Need not to adjust the position of locating column 4 when assembling in batches, directly adjustment gets final product as stated above again.
The new way adjustment belt tension that the utility model embodiment adopts, convenient and swift, be convenient to the rigger and grasp operating method, and cost is lower.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
