Abstract
This utility model is related to a kind of lockable mechanism of canvas top-fastener propping roller, it is characterised in that：Including support bar, ratchet, ratchet and bearing, the support bar is arranged on propping roller when in use, and the ratchet is arranged on and supports boom end and can rotate freely；The bearing is arranged on below support bar, and when in use in the frame of canvas top-fastener, the ratchet is fixedly mounted on bearing bearing, and ratchet position is corresponding with the detent positions.It is this utility model simple structure, compact, can be in the case where existing equipment structure not to be changed, effectively solving propping roller is because of Gravitational sliding problem, and will not increase excessive cost, safeguards also very convenient.
Description
Technical field
This utility model is related to a kind of lockable mechanism, the specifically lockable mechanism of canvas top-fastener propping roller.
Background technology
When paper machine canvas top-fastener is planned, inevitably needed this device slant setting sometimes.At this moment must consider
When canvas is changed, due to losing canvas tension force, the propping roller positioned at inclined plane can be brought not to canvas operation is changed because of Gravitational sliding
Just the problems such as.The mode for solving this problem in the past is to adopt the bearing housing with auto-lock function, but which is relatively costly, maintenance maintenance
Also it is inconvenient.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of canvas top-fastener propping roller
Lockable mechanism, it is its simple structure, compact, can be in the case where existing equipment structure not be changed, effectively solving propping roller is because of weight
Power downslide problem, and excessive cost will not be increased, safeguard also very convenient.
According to the technical scheme that this utility model is provided：The lockable mechanism of canvas top-fastener propping roller, it is characterised in that：Bag
Support bar, ratchet, ratchet and bearing are included, the support bar is arranged on propping roller when in use, and the ratchet is arranged on and supports
Boom end simultaneously can be rotated freely；The bearing is arranged on below support bar, and bearing is when in use installed in the machine of canvas top-fastener
On frame, the ratchet is fixedly mounted on bearing, and ratchet position is corresponding with the detent positions.
As further improvement of the utility model, on the ratchet, handwheel is connected with.
This utility model compared with prior art, has the advantage that：It is this utility model simple structure, compact, can be not
In the case of modification existing equipment structure, effectively solving propping roller is because of Gravitational sliding problem, and will not increase excessive cost, dimension
Shield is also very convenient.
Description of the drawings
Structural representations of the Fig. 1 for this utility model embodiment.
Specific embodiment
With reference to concrete drawings and Examples, the utility model is described in further detail.
As shown in the figure：The lockable mechanism of the canvas top-fastener propping roller in embodiment is mainly by support bar 1, ratchet 2, ratchet
4 and bearing 3 constitute, the support bar 1 is arranged on propping roller when in use, and the ratchet 2 is arranged on 1 end of support bar can
Rotate freely；The bearing 3 is arranged on below support bar 1, and bearing 3 is arranged in the frame of canvas top-fastener when in use, institute
State ratchet 4 to be fixedly mounted on bearing 3,4 position of ratchet is corresponding with 2 position of the ratchet.
During concrete application, as ratchet 2 can be rotated freely, under gravity, ratchet 2 is in overhang all the time；
When canvas is changed, due to losing canvas tension force, the propping roller positioned at inclined plane can be because of Gravitational sliding, when propping roller glides, spine
Pawl 2 is also moved down, and after propping roller downslide certain distance, 2 end of ratchet can be snapped onto on the ratchet 4 of lower section, ratchet 2 and spine
Wheel 4 coordinate realizes locking, it is to avoid propping roller glide to change canvas operation make troubles.
As shown in figure 1, in the present embodiment, handwheel 5 is connected with the ratchet 4, so can be tieed up with the convenient of mechanism
Repair maintenance.
