Window has reasonable in design, sound construction with anti-bending chain, extends chain service life, tensile load is strong, support bearing ability
By force, the advantages of chain drive stationarity.
In order to achieve the above objectives, the technical solution adopted in the utility model is：One kind pushing away the anti-bending bush(ing) chain of window, including：
Inner plate, outer plate, sleeve, roller and axis pin；The sleeve is arranged in the outside of axis pin, and sleeve passes through fitting side with axis pin
Formula is connected；The roller is arranged in the outside of sleeve, and roller is connected with sleeve by fitting mode；The inner plate is set
It sets in the both sides of roller, and inner plate is connected with sleeve by interference mode；The outer plate is arranged in the side of inner plate,
And outer plate is connected with inner plate by axis pin.
As advanced optimizing for the technical program, the utility model is a kind of to push away window inner plate described in anti-bending bush(ing) chain
Left end is in concave arc shape, and the right end of inner plate is in convex arc shaped.
As advanced optimizing for the technical program, the utility model is a kind of to push away window outer plate described in anti-bending bush(ing) chain
Left end is in convex arc shaped, and the right end of outer plate is in concave arc shape.
As advanced optimizing for the technical program, the utility model one kind pushing away window two inner plates described in anti-bending bush(ing) chain
Between be connected by outer plate.
As advanced optimizing for the technical program, the utility model one kind pushing away window sleeve described in anti-bending bush(ing) chain and rolling
It is clearance fit between son, and sleeve and inner plate are interference fit.
As advanced optimizing for the technical program, the utility model one kind push away window inner plate described in anti-bending bush(ing) chain with
The bottom surface of outer plate is both provided with arc-shaped groove.
Due to the application of the above technical scheme, the utility model has following advantages compared with prior art：
One kind of the utility model pushes away the anti-bending bush(ing) chain of window, have it is reasonable in design, service life is long, stretch
Load is strong, is less likely to occur bending when supporting sash and the advantages of chain drive stationarity.
Description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings：
Attached drawing 1 is a kind of schematic elevation view pushing away the anti-bending bush(ing) chain of window of the utility model；
Attached drawing 2 is a kind of schematic top plan view pushing away the anti-bending bush(ing) chain of window of the utility model.
Wherein：Inner plate 1, outer plate 2, sleeve 3, roller 4, axis pin 5.
Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
One kind described in the utility model as shown in Figure 1 and Figure 2 pushes away the anti-bending bush(ing) chain of window, including：Inner plate 1,
Outer plate 2, sleeve 3, roller 4 and axis pin 5；Sleeve 3 is arranged in the outside of axis pin 5, and sleeve 3 passes through fitting mode with axis pin 5
It is connected；Roller 4 is arranged in the outside of sleeve 3, and roller 4 is connected with sleeve 3 by fitting mode；The setting of inner plate 1 exists
The both sides of roller 4, and inner plate 1 is connected with sleeve 3 by interference mode；Outer plate 2 is arranged in the side of inner plate 1, and
Outer plate 2 is connected with inner plate 1 by axis pin 5.
Specifically, the left end of inner plate 1 be in concave arc shape, and the right end of inner plate 1 be in convex arc shaped, 1 right end of inner plate it is recessed
Arc is meshed with the convex arc of next group of 1 left end of inner plate and contacts, and when supporting sash, chain stress is less likely to occur to be bent, and carries
The high carrying enabling capabilities of chain.
Specifically, the left end of outer plate 2 be in convex arc shaped, and the right end of outer plate 2 be in concave arc shape, 2 right end of outer plate it is recessed
Arc is meshed with the convex arc of next group of 2 left end of outer plate and contacts, and when supporting sash, chain stress is less likely to occur to be bent, and carries
The high carrying enabling capabilities of chain.
Specifically, be connected by outer plate 2 between two groups of inner plates 1, it is compact-sized, it is connected firmly, improves chain
Tensile load ability.
Specifically, be clearance fit between sleeve 3 and roller 4, and sleeve 3 and inner plate 1 are interference fit, 4 sets of roller
It closes on sleeve 3, when work, roller is rolled along sprocket tooth profile, can be mitigated the abrasion of chain, be improved the wearability of chain, is covered
Cylinder 3 is that interference fit is fixedly connected with inner plate 1, and sound construction improves the intensity of chain.
Specifically, inner plate 1 and the bottom surface of outer plate 2 are both provided with arc-shaped groove, groove is meshed with sprocket, subtracts
The abrasion of light chain item and the gear teeth extends the service life of chain, improves chain drive stationarity.
