Abstract

The utility model relates to a high-strength bolt, and relates to a bolt. The high-strength bolt comprises a strengthened structure formed by an external nonmetal bolt body, a metal head (2) and metal rods (5), wherein the metal head (2) is arranged in a screwing head (1) at one end of a nonmetal bolt; and metal rods (5) are arranged in a middle polish rod (3) of the nonmetal bolt and in the external thread (4) at the other side of the nonmetal bolt. The high-strength bolt provided by the utility model is arranged once, and undesirable phenomena are not found when the high-strength bolt is used in an experiment, so that the high-strength bolt does not need to be maintained. The high-strength bolt provided by the utility model has good high temperature resistance and ageing resistance; by utilizing the high-strength bolt, the requirements of flame retardance, acid proofness and alkali proofness and the like can be achieved, thereby prolonging the service life and lowering the cost; as phenolic resin has good insulating property, the high-strength bolt provided by the utility model can be used for realizing good appeal of the insulating property, overcoming the defect that the insulation value is lowered after dust enters the periphery of the traditional bolt, and lowering the power consumption of the device and potential safety hazard, and can be used for effectively preventing electric shock accidents.

Description

A kind of high-strength bolt

[technical field]

The utility model relates to a kind of bolt, especially relates to a kind of high-strength bolt.

[background technique]

Known, in aluminium electrolysis shop, the fastening bolt that all left not of connection of a lot of equipment; Because the bolt that on the electrolytic bath door frame, uses must possess insulating property; So use nonmetal bolt to use usually, can reach the qualified requirement of insulation values, but at present commercially available nonmetal bolt working strength is too low as fastening piece; The nonmetal bolt of use is also arranged and be used insulation tube and felt pad, make it to meet the insulation values requirement of equipment; But in actual use, insulation values just can reduce when between bolt and insulation tube, getting into dust or other foreign material, makes the power consumption increase and has potential safety hazard; Maintenance workload reaches the Master Cost height greatly.

[summary of the invention]

In order to overcome the deficiency in the background technique; The utility model discloses a kind of high-strength bolt; Described high-strength bolt is through putting into the nonmetal body of bolt with ferrule, metallic rod, and not only intensity is guaranteed, and also has effect high temperature resistant, anti-aging and insulation.

In order to realize said goal of the invention, the utility model adopts following technological scheme:

A kind of high-strength bolt comprises the reinforced structure that the outside nonmetal body of bolt and ferrule, metallic rod form, and is provided with ferrule in the head screwing of nonmetal bolt one end, is provided with metallic rod in the middle part polished rod of nonmetal bolt and the outside thread of opposite side.

Described high-strength bolt, the screw head, polished rod, outside thread of said nonmetal bolt are the ferrule that forms of the composition of phenolic resin and high-strength structureal adhesives, the full inclusion of metallic rod.

Described high-strength bolt, the head of screwing of said nonmetal bolt is outer-hexagonal head, the hexagon head that caves in, round end or square spigot.

Owing to adopted technique scheme, the utlity model has following beneficial effect:

The described high-strength bolt of the utility model has reached non-maintaining purpose after installing and using, the utility model once mounting is not found bad phenomenon in experiment is used, reached Maintenance free; It is good to the utlity model has high temperature resistant aging quality resistance; Because traditional bolt felt pad, insulation tube are aging fast, workload and maintenance expense are big, use the utility model can reach requirements such as fire-retardant, acid-proof, alkali prevention, thereby have prolonged working life and reduced cost; Because phenolic resin has the good insulation performance performance, the utility model has been realized the demand that insulating property are good; The utility model has overcome and has got into the defective that insulation values reduces behind the dust around traditional bolt, has reduced the power consumption of equipment and has had potential safety hazard, uses the utility model can prevent the generation of electric shock accidents effectively.

[description of drawings]

Fig. 1 is the structural representation of the utility model.

Among the figure: 1, screw head; 2, ferrule; 3, polished rod; 4, outside thread; 5, metallic rod.

[embodiment]

Through following embodiment can be detailed explanation the utility model, the purpose of open the utility model is intended to protect all technological improvements in the utility model scope,

In conjunction with accompanying drawing 1 described high-strength bolt; Comprise the reinforced structure that the outside nonmetal body of bolt and ferrule 2, metallic rod 5 form; Be provided with ferrule 2 screwing in 1 of nonmetal bolt one end, be provided with metallic rod 5 in the middle part polished rod 3 of nonmetal bolt and the outside thread 4 of opposite side; Said nonmetal bolt screw 1, the ferrule 2 that polished rod 3, outside thread 4 form for the composition of phenolic resin and high-strength structureal adhesives, the full inclusion of metallic rod 5; Screwing of said nonmetal bolt 1 is outer-hexagonal head, the hexagon head that caves in, round end or square spigot.

Implement the described high-strength bolt of the utility model; Through with bolt screw 1, polished rod 3 and outside thread 4 parts use the conventional employed material of nonmetal bolt to be replaced by the resistant to elevated temperatures phenolic resin of high-strength insulation; And at phenolic resin interpolation high-strength structureal adhesives; In press tool, at first put into the nail-like intensive aspect of ferrule 2, metallic rod 5 formations; Injection phenolic resin adds with the mixture of high-strength structureal adhesives one time punching molded by the equipment HTHP, and wherein inner ferrule 2, metallic rod 5 are the #45 steel, have further increased the intensity of bolt; It is isolation layer that outside phenolic resin adds high-strength structureal adhesives; The utility model has not only been considered intensity but also taken into account insulation, is particularly suitable for aluminium electroloysis industry high temperature, high dust, highfield environment and uses down, because the utility model has reached the requirement of all insulation in being connected of equipment and metallic conductor.

The utility model does not detail part and is existing technology.
