Abstract
The utility model discloses a novel split pin which is characterized in that arc-shaped bulges (2) are arranged on two straight bars (3); an anti-falling elastomer for preventing convexes (5) capable of increasing friction force and arranged on the outer sides of the straight bars (3) from falling off is arranged between the two straight bars (3). The novel split pin has the advantages of being simple in structure, convenient to use, and difficult in falling or damage.
Description
Technical field
The utility model belongs to mechanical field, especially a kind of novel opening pin.
Background technique
Along with the construction of nearly 2 years electric transmission line is also in the middle of flourish, the load of electric transmission line carrying constantly increases, for ensureing the safe and stable operation of circuit, but because of electric transmission line multi-point and wide-ranging, long term exposure is in intermountain field again, in addition, and after existing cotter pin is installed, with pliers, cotter pin is broken into two with one's hands, cotter pin is stuck on screw.In work progress, personnel lack a sense of responsibility, and insert after cotter pin, fail to break into two with one's hands cotter pin, climate and environmetal impact simultaneously, and cotter pin easily comes off.
The cotter pin of circuit running king-rod tower come off or damaged situation comparatively common, if cotter pin comes off and does not mend in time dress and can make shaft tower bolt looseness come off, cause connecting gold utensil and wire and break, cause the circuit tripping operation of breaking down, potential potential safety hazard is comparatively serious.Mend at present dress or the work of construction opening pin, generally adopt interruption maintenance work, not only impact is subject to electric weight, has also strengthened O&M job costs, has reduced line security operation level.For protecting, " long-term stability " is existing that cotter pin is improved, the cotter pin after improvement can be more firmly, difficult drop-off, is line security stable operation establish a firm foundation.
Summary of the invention
The purpose of this utility model is, a kind of simple in structure, easy to use, difficult drop-off or damaged novel opening pin are provided.
The utility model is characterised in that: on two straight-bars (3), be equipped with arc convex (2), be provided with the elastomer of Drop-proof between two straight-bars (3), for the outside of Drop-proof straight-bar (3) is provided with the projection (5) of increasing friction force.
Described elastomer is spring, can be also shell fragment.
The utlity model has simple in structure, easy to use, difficult drop-off or damaged advantage.

Fig. 1: be the utility model embodiment 1 structural representation.
Fig. 2: be the real figure of the utility model.
Fig. 3: be the A-A sectional structure schematic diagram of Fig. 1.
Fig. 4: be the right TV structure schematic diagram of Fig. 3.
Shown in figure, being 1. cotter pin, is 2. arc convex, is 3. straight-bar, is 4. elastomer, is 5. projection.
Embodiment
On 1: two straight-bar of embodiment (3), be equipped with arc convex (2), between two straight-bars (3), be provided with the elastomer of Drop-proof, for the outside of Drop-proof straight-bar (3) is provided with the projection (5) of increasing friction force.
Described elastomer is spring.
Embodiment 2: the present embodiment and embodiment's 1 difference is: described elastomer is shell fragment.
Claims (2)
1. a novel opening pin, is characterized in that: on two straight-bars (3), be equipped with arc convex (2), be provided with the elastomer of Drop-proof between two straight-bars (3), the outside of straight-bar (3) is provided with projection (5).
2. novel opening pin as claimed in claim 1, is characterized in that: described elastomer is spring or shell fragment.
