Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of a kind of technical solution: 1. heat resistant type roller chains, including two turn
1, six axis of axis joins 2, two sleeves 4 of piece and four anti-decylizations 101, is connected with sleeve 4, sleeve 4 or so two in the middle part of shaft 1
Side is slidably connected, and there are two axis to join piece 2, and links up two shafts 1, two shafts apart from 4 farther away two axis connection pieces 2 of sleeve
1 two tops far from sleeve 4 are nested anti-decylization 101, and four anti-decylizations 101 are arranged at outermost side axle connection piece
2 outside, the axis connection piece 2 in shaft 1 are equipped with drop resistance device 3 between any two, are connected with fixed ring on the outside of drop resistance device 3
301,301 internal activity of fixed ring is connected with ball 303, and axis connection 2 inner wall of piece being oppositely arranged two-by-two is equipped with ball grooves 302,
Fluted 401 are fixedly connected on the outside of sleeve 4.
Further, setting, and the setting in the shape of an " I " of its section, and groove 401 are welded between sleeve 4 and groove 401
It is arranged in cambered surface, by above-mentioned setting, when so that the present apparatus being mounted on latch, latch can tend under the action of groove 401
Put forth effort in the middle part of sleeve 4, avoids latch in this way and axis connection piece 2 is squeezed, reached protective device functional structure
Effect, and then solve that the design of existing design structure is unreasonable, latch is easy to squeeze the axis connection piece 2 in 4 outside of sleeve
Pressure, thereby reduces the deficiency of the service life of device.
Further, ball 303 is equipped with 12, and fits closely between ball 303 and ball grooves 302, by above-mentioned
Setting, forms a drop resistance device 3, this kind drop resistance device 3 can form isolation, while ball between axis connection piece 2 close two-by-two
303 can reduce the friction of device again, thereby reduce the heat generation rate of device, in addition, the gap between axis connection piece 2 also can will be hot
Amount is exported, and has not only realized the water conservancy diversion to device heat, but also reduce the fever of device from the root, and then increase device
Heat resistance, it is simple to solve existing design structure, and it is serious that axis joins frictional heating between piece 2, and not to the release efficiency of heat
It is good, and then lead to the deficiency of poor heat resistance.
Further, setting is welded between anti-decylization 101 and shaft 1, is arranged by above-mentioned welding, so that device is more steady
Gu it solves using nested setting between existing design anti-decylization 101 and shaft 1, it is not firm insufficient enough.
Further, do not contacted between close axis connection piece 2 two-by-two, and its distance in ball 303 diameter one point one
It is arranged again, above-mentioned setting ensure that the running of ball 303 by enough spaces.
Working principle: firstly, in place by device installation, guaranteeing the stabilization of device, to the modules of device
It is detected, during which, setting, and the setting in the shape of an " I " of its section is welded between sleeve 4 and groove 401, and groove 401 is in arc
Face setting, by above-mentioned setting, when so that the present apparatus being mounted on latch, latch can be intended under the action of groove 401 to
The middle part of sleeve 4 is puted forth effort, and is avoided latch in this way and is squeezed axis connection piece 2, has reached the effect of protective device functional structure
Fruit, and device since ball 303 is equipped with 12, and fits closely to be formed in running between ball 303 and ball grooves 302
One drop hinders device 3, so isolation can be formed between axis connection piece 2 close two-by-two, while ball 303 can reduce device again
Friction, thereby reduces the heat generation rate of device, in addition, the gap between axis connection piece 2 can also export heat, it is both real
Show the water conservancy diversion to device heat, and reduced the fever of device from the root, and then increases device heat resistance, anti-decylization
Setting is welded between 101 and shaft 1, is arranged by above-mentioned welding, so that device is more firm, solves existing design anticreep
It is not firm insufficient enough using nested setting between ring 101 and shaft 1.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
