Abstract
The utility model relates to a nut, in particular to an anti-theft nut which is widely applied to devices for power, roads and the like. The six-edge anti-theft nut with drilled side part and built-in steel balls comprises a nut body which has a hollow structure internally, and six edges and edge surfaces are arranged at the outer part of the nut body. The anti-theft nut is characterized in that small holes facing the inner part of the nut body are arranged on the edge surfaces or the edges, an opening is arranged at the intersected position between the small holes and the hollow structure, and the small hole in the inner part of the nut body, corresponding to the opening, has the structure that the small hole becomes shallower along the tightening direction; the small holes is internally provided with springs and the steel balls, and the openings of the small holes are sealed. The six-edge anti-theft with the drilled part and the built-in steel balls has the advantages as follows: the manufacturing is easy, the cost is low and the steel balls and the springs at the inner part of the nut body are not easy to fall off.
Description
Technical field
The utility model relates to nut, specifically relates to a kind of anti-theft nut, and it is widely used in the facilities such as electric power, highway.
Background technique
Anti-theft nut has in the nut body inboard along tightening direction groove from depth to shallow, built-in steel ball of groove and spring, such anti-theft nut can use as normal nut when tightening, when unloading because its inner structure, steel ball is positioned at the more shallow zone of groove, keep out and continue to unload, reached antitheft effect; In the prior art, such groove is processed in nut inside, has the steel ball and the caducous shortcoming of spring of processed complex, manufacture cost height, nut body inside.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned shortcoming, the anti-theft nut that provides six rib sidepieces of a kind of easy to manufacture, cost is low, nut body is inner steel ball and spring difficult drop-off to hole built-in steel ball.
The technical solution of the utility model is achieved in that the hole anti-theft nut of built-in steel ball of six rib sidepieces, comprise nut body, nut body inside has hollow structure, the nut body outside has six ribs and faceted pebble, it is characterized in that on described faceted pebble or rib, having aperture towards nut body inside, aperture has opening with hollow structure intersection, and the aperture in nut body inside relative with opening has along tightening direction structure from depth to shallow; Built-in spring of aperture and steel ball, the opening of aperture is shut.
The beneficial effects of the utility model are: the hole anti-theft nut of built-in steel ball of six such rib sidepieces has the advantage of steel ball and spring difficult drop-off easy to manufacture, that cost is low, nut body is inner.
Description of drawings
Fig. 1 is a tangent plane structural representation of the present utility model.
Wherein 1, nut body 2, hollow structure 3, rib 4, faceted pebble 5, aperture 6, opening 7, spring 8, steel ball
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the hole anti-theft nut of built-in steel ball of six rib sidepieces, comprise nut body 1, nut body 1 inside has hollow structure 2, nut body 1 outside has six ribs 3 and faceted pebble 4, it is characterized in that having on described faceted pebble 4 or rib 3 aperture 5 towards nut body inside, aperture 5 has opening 6 with hollow structure 2 intersections, has along tightening direction structure from depth to shallow with the opening 6 relative apertures 5 in nut body inside; Built-in spring 7 of aperture and steel ball 8, the opening of aperture 5 is shut.
Described shutting is meant that can rivet, weld dead, unclassified stores fills out the situation of waiting indefinitely, in a word as long as steel ball and spring are fixed on the aperture the inside.
