Description
Technical field
The utility model relates to mechanical parts field, particularly a kind of bolt plastics protective cap.
Background technique
Bolt is the cylindrical threaded fastening piece of adapted nut, by head and a screw rod class fastening piece dimerous, needs and nut screw connection, for being fastenedly connected two parts with through hole.
Existing bolt designs tradition mostly, and bolt installs rear easy corrosion, and after bolt head corrosion more stressed easy generation plastic deformation even rupture, badly influence its use.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of bolt plastics protective cap, can be enclosed within the plastics protective cap of bolt head by design, is out of shape after getting rusty to prevent bolt head.
For achieving the above object; the utility model provides following technological scheme: a kind of bolt plastics protective cap; it is characterized in that: described bolt plastics protective cap comprises hemispheric cap body; cap body base plane center is provided with the bolt hole of a positive hexagon; cap body and bolt hole wall thickness thinnest part are not less than 20 ㎜, and the bolt hole bilateral symmetry bottom cap body is provided with the sled hole of a rectangle.
Preferably, described cap body is formed by thermoplastic material manufacture.
Preferably, the bolt hole bottom described cap body and the mutual interference fit of bolt head.
Preferably, the width in the sled hole bottom described cap body is not less than 6 ㎜.
The beneficial effect of above technological scheme is adopted to be: the hemispheric base plane center of this bolt plastics protective cap is provided with the bolt hole of a positive hexagon; bolt hole bilateral symmetry bottom cap body is provided with the sled hole of a rectangle; can bolt head diameter be nested in bolt hole during use; the cap body of hemisphere design can allow water flow away from the side efficiently; effective anti-sealing drenches into bolt; effectively prevent bolt from getting rusty, prevent bolt to be out of shape.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is the worm's eye view of a kind of bolt plastics of the utility model protective cap;
Fig. 2 is the plan view of a kind of bolt plastics of the utility model protective cap.
Wherein, 1-cap body, 2-bolt hole, 3-sled hole.
Embodiment
The preferred implementation of a kind of bolt plastics of the utility model protective cap is described in detail below in conjunction with accompanying drawing.
Fig. 1 and Fig. 2 shows the embodiment of a kind of bolt of the utility model plastics protective cap: this bolt plastics protective cap comprises hemispheric cap body 1; cap body 1 base plane center is provided with the bolt hole 2 of a positive hexagon; cap body 1 and bolt hole 2 wall thickness thinnest part are not less than 20 ㎜; ensure enough thickness; prevent cap body 1 from breaking; bolt hole 2 bilateral symmetry bottom cap body 1 is provided with the sled hole 3 of a rectangle, and sled hole 3 conveniently can lever up this bolt plastics protective cap with instrument.
Composition graphs 1 and Fig. 2, cap body 1 is formed by thermoplastic material manufacture, good airproof performance, can available protecting.Bolt hole 2 bottom cap body 1 and the mutual interference fit of bolt head, laminating closely, can effectively prevent into water.The width in the sled hole 3 bottom cap body 1 is not less than 6 ㎜.
Bolt head diameter can be nested in bolt hole 2 during use; the cap body 1 of hemisphere design can allow water flow away from the side efficiently; effective anti-sealing drenches into bolt; effectively prevent bolt from getting rusty; bolt is prevented to be out of shape; the design in sled hole 3, facilitate dismounting, this bolt plastics protective cap is applicable to being applied on outdoor clamping bolt.
Above is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
