Description
Technical field
The utility model relates to a kind of nut, particularly a kind of nut for low temperature environment.
Background technique
Nut often uses the parts realizing being fastenedly connected between bolt in industry.But in low temperature environment, certain deformation can be there is in metal, and make the screw thread that can realize between nut with bolt being connected can be subject to cold events, make to depart from each other between the screw thread of nut and the screw thread of bolt, cause nut to bolton loosely, thus there is bolt falling, cause the problem of security incident.
Model utility content
The technical problems to be solved in the utility model is to overcome the defect easily causing bolt falling when existing nut is used in low temperature environment, providing a kind of nut for low temperature environment.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of nut for low temperature environment, it includes: a nut body, one nut cap, its feature is, described nut body comprises a connection body, one connects boss, described connection body is the female cylinder of a tool, described connection boss is that a diameter is greater than described connection body and the female cylinder of tool, the diameter of the inwall of described connection body is identical with the diameter of the inwall of described connection boss, one end of described connection boss is fixedly connected with described one end being connected body, the other end of described connection boss has an annular groove, there is in described annular groove some boss screws, one end of described nut cap has the groove matched with described annular groove, the diameter of described nut cap is identical with the diameter of described connection boss, described nut cap is provided with the nut cap screw matched with described boss screw.After bolt is screwed into nut body, in the afterbody part embedded rings connected in star of bolt, another part protrudes from outside annular groove.Now, nut cap is pressed in the afterbody of bolt, utilizes the groove on nut cap, among the embedded rings connected in star making the afterbody of bolt complete and the groove of nut cap.Meanwhile, use bolt, through nut cap screw, boss screw, realize fixing between nut cap and nut body.
Preferably, described connection body also comprises a tie layer obtained by heat insulation material, and the inwall of described tie layer is fixed with the described outer wall being connected body, and the outer wall of described tie layer is provided with some outer wall screws.
Preferably, the quantity of described boss screw is three.
Preferably, the edge of described nut cap has the vertically some and threaded positioning groove of inwall tool, and the edge of described connection boss has the threaded boss positioning groove of inwall tool that some and described positioning groove matches.
Preferably, the quantity of described positioning groove is 3.
Preferably, described connection body is integrally formed with the described boss that is connected.
Positive progressive effect of the present utility model is: to make between nut and bolt fixing more tight, prevent the situation that the bolt caused because of low temperature comes off from nut.

Embodiment
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
Embodiment
Understood incorporated by reference to Fig. 1-2, a kind of nut for low temperature environment, comprising: nut body 1, nut cap 2.Nut body 1 comprises a connection body 11, and connects boss 12, and wherein, connecting body 11 is a cylinder with internal thread 16, and connecting boss 12 is that a diameter is greater than connection body 11 and has the cylinder of internal thread 16.The diameter connecting the inwall of body 11 is identical with the diameter of the inwall connecting boss 12, and this makes the inwall connecting body 11 jointly form nut body 1 and the bolted part that is spirally connected with the inwall being connected boss 12.
Understood incorporated by reference to Fig. 1, the one end connecting boss 12 is fixedly connected with the one end being connected body 11, and both are one of the forming obtained.The other end connecting boss 12 has an annular groove 13, has three boss screws 14 in annular groove 13.One end of nut cap 2 has the groove matched with annular groove 13, and the diameter of nut cap 2 is identical with the diameter connecting boss 12, and nut cap 2 is provided with the nut cap screw 24 matched with boss screw 14.
Understood incorporated by reference to Fig. 1, there is better fastening effect in order to make nut cap 2 with being connected between boss 12,3 can be offered vertically and the threaded positioning groove 27 of inwall tool at the edge of nut cap 2, meanwhile, 3 threaded boss positioning grooves 17 of inwall tool matched with positioning groove 27 are also offered at the edge connecting boss 12.When nut cap 2 be connected after boss 12 combines, the bolt using a diameter and positioning groove 27 and boss positioning groove 17 to match by nut cap 2 be connected boss 12 and be screwed together.
Being understood incorporated by reference to Fig. 1, better being connected effect to obtain, prevented because temperature reduces conduction to highi degree of accuracy change in shape that nut brings, can at the sheathed tie layer 15 of outer wall connecting body 11.Tie layer 15 adopts heat insulation material to obtain, and the inwall of tie layer 15 is fixed with the outer wall being connected body 11, and the outer wall of tie layer 15 is provided with some outer wall screws, and described outer wall screw is for realizing fixing between tie layer 15 and miscellaneous part.
Understood incorporated by reference to Fig. 1, during use, first bolt is screwed in nut body 1, subsequently, covers nut cap 2.Because nut body 1 has annular groove 13, so in the afterbody part embedded rings connected in star of bolt; Nut cap 2 has the groove matched with annular groove 13, so another part of the afterbody of bolt is inserted within the annular groove of nut cap 2.Subsequently, bolt will be used through nut cap screw 24, boss screw 14, realize fixing between nut cap 2 and nut body 1.In order to prevent the disengaging of nut cap 2 and nut body 1, bolt can be used further to pass positioning groove 27, boss positioning groove 17 after, fixing between stiffnut lid 2 and nut body 1.
Although the foregoing describe embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these mode of executions, but these change and amendment all falls into protection domain of the present utility model.
