Abstract
The utility model discloses a link joint fixed knot constructs for on chain, including link joint, outer chain plate and two round pin axles of locating on the link joint, the one end closing plate of round pin axle, the other end is equipped with stopping ring groove, sets up the retaining ring in the stopping ring groove, and the round pin axle passes outer chain plate block by the retaining ring. Through processing out stopping ring groove in round pin epaxial relevant position department, utilize the retaining ring in locating stopping ring groove to block outer chain plate when assemble with chain inner link unit, the retaining ring is processed according to retaining ring standard for the axle, is thickness thickeied, for 2 5mm, spring steel for the material, thermal treatment 48HRC~53HRC has high wearability, the utility model discloses it is all very convenient to change, to maintain, to dismantle.
Description
Technical field
This utility model is related to the assembling structure on chain between two neighboring chain unit, and in particular to a kind of to be used for chain
Chain board fixing structure on bar.
Background technology
Using the occasion of chain bucket hoist, it is very crucial that the safe handling of chain normally runs quality；The chain of chain
Plate fixed form also compare it is many, have using riveting, also have using bearing pin punching drive the rivets etc., but using rivet pin
Axle, carrier bar reform into non-dismountable property, and maintenance is changed and all bothered very much, and dismounting is destructive, not reproducible utilization；Using riveting
Nail, although convenient using changing, but the hardness of rivet is very low, and also pole is not wear-resisting, and live Jing rivet abrasion often occurs and causes chain
Plate abjection causes to fall the generation of chain accident, many elevator producers all finding effective solution.
The content of the invention
This patent is directed to problems of the prior art, there is provided a kind of chain board fixing structure on chain, this product
Product have to be changed, keeps in repair, dismantling the characteristics of being quite convenient to.
For solving above-mentioned technical problem, the technical scheme that this utility model is adopted is：A kind of chain on chain
Board fixing structure, including the bearing pin of carrier bar, outer plate and two on carrier bar, one end connection carrier bar of bearing pin, the other end
It is provided with circlip groove, circlip groove and back-up ring is set, bearing pin is blocked by back-up ring through described outer plate.
Used as the preferred of such scheme, the material of back-up ring is spring steel.
Used as the preferred of such scheme, the width of circlip groove is 2-5mm, and back-up ring Matching installation is in described circlip groove.
The beneficial effects of the utility model are：Circlip groove is processed by the corresponding position on bearing pin, with chain
Outer plate is blocked using the back-up ring in circlip groove when inner link unit is assembled, back-up ring carries out adding according to shaft block ring standard
Work, thickness thicken, and it is 2-5mm to match with back-up ring well width, material spring steel, and heat treatment 48HRC～53HRC, with high
Wearability, this utility model change, maintenance, dismounting be quite convenient to.
Description of the drawings
Fig. 1 is the installation diagram of this utility model and chain inner link unit；
Fig. 2 is the axonometric chart of Fig. 1.
Specific embodiment
With reference to embodiment, specific embodiment of the present utility model is further described.
As shown in Figure 1-2, a kind of chain board fixing structure on chain, sets including carrier bar 1, outer plate 2 and two
Bearing pin 3 on carrier bar, one end connection carrier bar of bearing pin, the other end are provided with circlip groove, circlip groove and arrange back-up ring 4, and bearing pin is worn
Cross described outer plate to be blocked by back-up ring.The material of back-up ring is spring steel.The width of circlip groove be 2-5mm, back-up ring Matching installation
In described circlip groove.
During use, this utility model is arranged on overall chain between two neighboring chain inner link unit 5, during assembling,
Two bearing pins initially pass through head end and the end of two neighboring chain inner link unit, are then passed through outer plate, and back-up ring is arranged on gear
In ring recess, back-up ring blocks outer plate.
For a person skilled in the art, still the technical scheme described in foregoing embodiments can be repaiied
Change, or carry out equivalent to which part technical characteristic, all within spirit of the present utility model and principle, that what is made is any
Modification, equivalent, improvement etc., should be included within protection domain of the present utility model.
