Abstract
The utility model relates to a fastener which is used for various mechanical facilities and comprises a pentagonal or sseptilateral nut, the outer part of which is sheathed with a bowl-shaped gasket. An edge of a vertical surface in the bowl-shaped gasket is provided with a convex pin. The lower bottom edge of the vertical surface is outwards provided with a convex pin or a rib or a groove. The inner part of the bowl-shaped gasket is provided with a dentate piece which can be contained and matched. Teeth of the outer edge of the dentate piece are anastomosed with the convex pin on the edge of the vertical surface in the bowl-shaped gasket. A central inner hole of the dentate piece is anastomosed with the outer edge of the nut. A waterproof inner cover or a waterproof outer cover is installed on the position of an opening of the vertical surface of the bowl-shaped gasket. The shape of a dummy club of the cover surface of the waterproof inner cover or the waterproof outer cover is identical with the outer edge of the nut. The center of the dummy club is provided with a threaded hole which is identical with the nut. The edge of the waterproof outer cover is coated with fluorescent paint. Because the nut of the utility model adopts the pentagonal or sseptilateral heterotype nut, a conventional tool can not be used for start-up and a theftproof problem is solved better. The dentate piece of the fastener is tightly meshed with the convex pin of the bowl-shaped gasket. The nut can not be loosened under the function of external force. The waterproof cover can have the functions of rust prevention and alarm.
Description
Technical field
The utility model relates to the fastening piece of a kind of use on all kinds of mechanical facilities.
Background technique
In the fastening piece that uses on the facility such as traffic, municipal administration, normally adopt hexagon nut. often the someone dismantles fastening piece in unserviced place, steals equipment, causes losing, become flexible, damaging of equipment, these departments of giving cause very big loss, and lead to various accidents.The inventor is in " nut and spanner thereof " (patent No.: 00224282.6) mainly provide a kind of pentagon or heptagonal special-shaped nut and supporting spanner thereof of application on March 3rd, 2000, this patent has solved the antitheft problem of fastening piece, but do not solve problems such as locking, antirust, so that prior art is still waiting is perfect.
Summary of the invention
Technical problem to be solved in the utility model is: at the easy pine that exists in the existing fastening piece, the problem of easily becoming rusty and lacking alarm function, and provide a kind of fastening piece of locking, antitheft and tool warning effect.
Technical solution adopted in the utility model is: it comprises a pentagon or heptagonal nut, and nut is with a bowl-type rubber pad circle outward, on the vertical face sides protruding pin is arranged in the bowl-type rubber pad circle, and the facade bottom has end protruding pin or the rib or the groove of location outwardly; Have in the bowl-type rubber pad circle and can hold the gear piece of joining, the protruding pin in outer heel teeth of gear piece and the bowl-type rubber pad circle on the vertical face sides matches, and gear piece central bore and nut outside match; The facade opening of bowl-type rubber pad circle is equipped with waterproof inner cap or waterproof enclosing cover, and the capping boss shape of waterproof inner cap or waterproof enclosing cover is identical with the nut outside, and there is the tapped hole identical with nut at the boss center.Scribble fluorescence paint on the limit of waterproof enclosing cover.
The beneficial effects of the utility model: what adopt because of nut of the present utility model is pentagon or heptagonal special-shaped nut, can not start with conventional instrument, has solved antitheft problem well; The protruding pin of gear piece of the present utility model and cup packing is tightly killed, and nut can not become flexible under the effect of external force; Waterproof cover can play effect antirust and caution.
