Abstract
A cotter pin mechanism comprises an inserting rod, a fixing part and a clamping spring. A circular groove is formed in the lateral wall at one end of the inserting rod in the circumferential direction. A through hole is formed in the end surface of the fixing part and the inserting rod is inserted into the through hole in a connecting mode. Two ends of the clamping spring are folded towards the same side to form a lateral plate and a base plate. A groove is formed in the edge of the base plate. The clamping spring is connected on the fixing part in a sleeved mode. The cotter pin mechanism has the advantages of being capable of being used repeatedly, free of damage, fast in disassembly and assembly, convenient to use, safe in using, and capable of replacing a traditional cotter pin.
Description
Technical field
The utility model relates to a kind of cotter pin mechanism.
Background technique
Along with modern life joint gathers continuous quickening, under the condition that can realize purpose, constantly simplify, constantly also refinement of essence, and the instrument that traditional cotter pin need to be employed needle-nose pliers and so on is twisted cotter pin and directly just can be taken off, also be so during assembling, need twist cotter pin and curvedly just can play fixing effect, this so that cotter pin just be out of shape after once using, be difficult for for the second time use, dismounting trouble, awkward problem, can't have satisfied the life style that the modern fast joint of people gathers.
Summary of the invention
The utility model for easily damage in the existing cotter pin mechanism Reusability situation, dismounting trouble, awkward problem, proposed a kind ofly can Reusability not damage, dismounting is quick, safe cotter pin mechanism easy to use.
Cotter pin described in the utility model mechanism is characterized in that: comprise inserted link, fixed block, jump ring, the sidewall of described inserted link one end is along circular groove circumferentially is set; The through hole of grafting inserted link is set on the end face of described fixed block; Described jump ring two ends form side plate and base plate to the homonymy turnover, on the edge of described base plate groove are set, and described jump ring is socketed on the described fixed block.
On the sidewall of described fixed block positioning convex point is set.
The number of described positioning convex point is 2.
Distance between 2 described positioning convex points is greater than the width of described jump ring.
On the side plate edge of described jump ring pressing plate is set.
Described inserted link is L-type.
During installation, the edge that first jump ring is arranged groove outwards is socketed on the fixed block, then an end that inserted link is arranged circular groove inserts in the through hole of fixed block, the circular groove of this moment just exposes through hole, then will be socketed in the outside clawback of jump ring on the fixed block, will get final product in the insertion of the groove on the jump ring circular groove; During dismounting, only need the interior thruster of jump ring to fixed block, so that groove breaks away from circular groove, then inserted link can be broken away from from fixed block, realize dismounting.
The beneficial effects of the utility model are: the energy Reusability does not damage, dismounting is quick, safety easy to use, has replaced traditional cotter pin.

Embodiment
Further specify the utility model below in conjunction with accompanying drawing
With reference to accompanying drawing:
Cotter pin described in the utility model mechanism comprises inserted link 1, fixed block 2, jump ring 3, and the sidewall of described inserted link 1 one ends is along circular groove 11 circumferentially is set; The through hole 21 of grafting inserted link 1 is set on the end face of described fixed block 2; Described jump ring 3 two ends form side plate 31 and base plate 32 to the homonymy turnover, and groove 321 is set on the edge of described base plate 32, and described jump ring 3 is socketed on the described fixed block 2.
Positioning convex point 22 is set on the sidewall of described fixed block 2.
The number of described positioning convex point 22 is 2.
The distance that 2 described positioning convex points are 22 is greater than the width of described jump ring 3.
On the edge of the side plate 31 of described jump ring 3 pressing plate 311 is set.
Described inserted link 1 is L-type.
During installation, the edge that first jump ring 3 is arranged groove 321 outwards is socketed on the fixed block 2, then an end that inserted link 1 is arranged circular groove 11 inserts in the through hole 21 of fixed block 2, the circular groove 11 of this moment just exposes through hole 21, then will be socketed in the jump ring 3 outside clawbacks on the fixed block 2, the groove 321 on the jump ring 3 will be inserted circular groove 11 interior getting final product; During dismounting, only need the interior thruster of jump ring 3 to fixed block 2, so that groove 321 breaks away from circular groove 11, then inserted link 1 can be broken away from from fixed block 2, realize dismounting.
The described content of this specification embodiment only is enumerating the way of realization of model utility design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reaches the equivalent technologies means that design can be expected according to the utility model in those skilled in the art.
