Description
Technical field
The utility model relates to a kind of joint structure, especially relates to a kind of a kind of permanent joint structure can applied in fields such as lathe, Transit Equipment, wind power plant, harbour facilities, engineering mechanical device, plastic machinery equipment, light fixture, elevator, motors.
Background technique
At present, at mechanical field, such as, lathe, wind power plant engineering mechanical device field, all need the structure using joint, existing structure, shown in Fig. 1, it comprises the body of bolt 1, panel body 2, the center of this panel body 2 is provided with circular through hole, this manhole wears for the body of bolt 1, because the body of bolt 1 and this manhole are all circular, after wearing, during the other end tightening nut body (not shown) of the body of bolt 1, this body of bolt can rotate relative to panel body 2, therefore, when mounted, need to be fixed at the other end utensil of the body of bolt 1.Its unreasonable structure, installation process is complicated, and structure stability is poor, inconvenient fitting operation.
As can be seen here, all there is significantly not enough and defect in existing joint structure and use, urgently improve further.
Model utility content
The purpose of this utility model is to provide a kind of permanent joint structure, and make it have structure simple, during use, installation efficiency is high, easy to use, the advantage that cost is low.
For solving the problems of the technologies described above, a kind of permanent joint structure of the present utility model, it comprises the body of bolt, nut body and panel body, described panel body is provided with the non-circular through hole passed for the described body of bolt, the shape of the cross section of the described body of bolt is identical with the shape of described through hole, described nut body coordinates with the described body of bolt and is fixed on panel body by the described body of bolt, the described body of bolt is through after the through hole of described panel body, and the described body of bolt can not rotate relative to described panel body.
Through hole on described panel body is oval.
Described body of bolt upper part is not provided with connecting thread, to match with the structure of the through hole on panel body.
The cross section of described nut body is circular, and it is rotatable is sheathed on the body of bolt, is fixed on panel body by the body of bolt.
The described body of bolt is the tubular structure of inner hollow.
The described body of bolt, nut body and panel body adopt metallic material or plastic material.
The beneficial effects of the utility model are:
The utility model permanent joint structure, it has the body of bolt design corresponding with through hole on panel body, and make the utility model structure simple, easy to use, save labour force, increase work efficiency, structure is more firm.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Accompanying drawing explanation
Above-mentioned is only the general introduction of technical solutions of the utility model, and in order to better understand the utility model, below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Fig. 1 is the structural representation of prior art joint;
Fig. 2 is permanent joint structural representation of the present utility model;
Fig. 3 is the structural representation of the panel body of permanent joint structure of the present utility model;
Fig. 4 is the scheme of installation of permanent joint structure of the present utility model.
Embodiment
Please refer to shown in Fig. 2 to Fig. 4, permanent joint structure of the present utility model, it comprises the body of bolt 1, nut body 4 and panel body 2, panel body 2 is provided with the non-circular through hole passed for the body of bolt 1, the shape of the cross section of the body of bolt 1 is identical with the shape of through hole, nut body 4 coordinates with the body of bolt 1 and is fixed on panel body 2 by the body of bolt 1, the body of bolt 1 is through after the through hole of panel body, the body of bolt 1 can not rotate relative to panel body 2, in addition, also packing ring 3 can be set between panel body 2 and the body of bolt 1, be beneficial to better stable fixing.
Concretely, through hole on panel body 2 is oval or other shapes, such as, through hole on this panel body is the figure of the major arc string composition corresponding thereto of circle, the cross section of the corresponding body of bolt 1 is corresponding with the shape of this through hole, namely the body of bolt 1 upper part is not provided with connecting thread, to match with the structure of the through hole on panel body 2.The screw thread particularly corresponded to by the body of bolt 1 on the body of bolt 1 of the side of the relative string of arc is cut flat, to make the body of bolt 1 and this through hole drive fit.
Nut body 1 of the present utility model, it is rotatable is sheathed on the body of bolt 1, the body of bolt 1 is fixed on panel body 2, its cross section is circular, the worm structure arranged in this nut body 1 is corresponding with the screw thread that the body of bolt 1 is arranged, smoothly nut body 4 choosing can be filled to panel body 2 position, make, under the acting in conjunction of nut body 4 and the body of bolt 1, to be fixedly connected with panel body 2.
In addition, the body of bolt 1 of the present utility model is the tubular structure of inner hollow, and it can be used as fluid passage and uses, and is set to this kind of structural formula, and this permanent joint structure can be applied in the equipment of conveying fluid, expands its Applicable scope.
Preferably, the body of bolt 1 of permanent joint structure of the present utility model, nut body 4 and panel body 2 adopt metallic material or plastic material, also can other suitable materials, are not here limited, as long as be applicable to this structure.
Permanent joint structure of the present utility model, when practicality, first, is arranged in the through hole on panel body by the body of bolt 1, because this through hole is non-circular structure, the body of bolt 1 does not rotate relative to panel body 2.Then, by nut body from the body of bolt can screw terminal, screwed in by nut body, in the process that nut body rotates, body of bolt opposing nut body is fixed, and thus, does not need the top of other people or oneself instrument fixing bolt body.Finally, nut body is rotated in place.
The above; it is only preferred embodiment of the present utility model; not do any pro forma restriction to the utility model, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in protection domain of the present utility model.
