Abstract
The utility model relates to a locking cover-shaped nut and belongs to a fastener. The locking cover-shaped nut comprises a nut body and a nut cover connected to one end of the nut body, wherein a threaded through hole is formed on the nut body; a blocking sheet and a spring are arranged in an inner cavity of the nut cover; the blocking sheet is adhered to the end face of the nut body; and the spring is propped between the blocking sheet and the nut cover. The utility model has the advantage that the locking cover-shaped nut has good locking function without the need of a spring washer.
Description
Technical field:
The utility model relates to a kind of fastening piece, specifically is a kind of Anti-loosing cap-shape nut.
Background technique:
Cap nut is tightened on bolt usually, the effect that connects fastening component is played in the end of threaded stem, when using common cap nut and bolt to lock component, in order to prevent the loosening of cap nut, general elder generation is tightened on the bolt end to cap nut again after bolt puts spring washer, rely on the elastic force of spring washer to increase match with bolt frictional force between the screw thread of cap nut, and then prevent the loosening of cap nut, although this method can well play the locking effect of cap nut, but also there is a deficiency, that is exactly before screwing on cap nut, to put spring washer at bolt first, use so just cumbersome.
The model utility content:
The technical problems to be solved in the utility model is to provide a kind of the needs to put the Anti-loosing cap-shape nut that spring washer can have better anti-loosing effect at bolt first.
Technical solution of the present utility model is, provide a kind of Anti-loosing cap-shape nut with following structure: comprise nut body and the nut cap that is connected to nut body one end, the nut body is provided with tapped through hole, wherein, be provided with catch and spring in the inner chamber of nut cap, catch is attached on the end face of nut body, and spring top is between catch and nut cap.
After adopting above structure, compared with prior art, the utility model Anti-loosing cap-shape nut has the following advantages: to rely in use spring washer to carry out locking different from common cap nut, owing to being provided with catch and spring in the inner chamber of the nut cap of the utility model Anti-loosing cap-shape nut, catch is attached on the end face of nut body, and spring top is between catch and nut cap.When the utility model Anti-loosing cap-shape nut is tightened on the bolt end, the end of bolt can promote catch and move, thereby make spring contraction produce the elastic deformation force, rely on the elastic deformation force of spring to replace the elastic force of spring washer to prevent the loosening of cap nut, therefore, the utility model Anti-loosing cap-shape nut does not need spring washer can have preferably anti-loosing effect.
Description of drawings:
Fig. 1 is that the master of the utility model Anti-loosing cap-shape nut looks the sectional structure schematic diagram.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model Anti-loosing cap-shape nut is described further:
As shown in Figure 1, in this embodiment, the nut cap 5 that the utility model Anti-loosing cap-shape nut comprises nut body 2 and is connected to nut body 2 one ends, nut body 2 is provided with tapped through hole 1, be provided with catch 3 and spring 4 in the inner chamber of nut cap 5, catch 3 is attached on the end face of nut body 2, and spring 4 withstands between catch 3 and the nut cap 5.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
