Abstract
The utility model provides a connecting piece, which relates to the mechanical field, and comprises a polygonal cylinder upper portion, a top washer and a cylinder lower portion, wherein through holes are arranged on the connecting piece along a center shaft, and inner threads are optionally arranged in the through holes. The connecting piece can solve the problem of threaded connection failure caused because the ring number of the inner threads on metal sheets with small thickness is less. The connecting piece has the advantages that the connecting piece is convenient to install and improves production efficiency.
Description
Technical field
The utility model relates to a kind of link of mechanical field, is specifically related to a kind of internal thread connecting piece.
Background technique
In mechanical field, between sheet metal and miscellaneous part, conventionally use screw bolt and nut to be connected.But when sheet metal is pipe fitting or formation cavity, processing staff is difficult at the both sides of sheet material construction bolt and nut simultaneously, operation easier is higher.For addressing this problem, also can in the hole of metal sheet, internal thread be set, direct and miscellaneous part is threaded connection.But, when the thickness of sheet metal hour, the internal thread number of turns on sheet metal is very few, this will make bolt skid and make to be threaded inefficacy.
Model utility content
In order to solve the problems of the technologies described above, the purpose of this utility model is to provide a kind of link, and it can solve the very few problem of the internal thread number of turns on the sheet metal of less thickness, and has conveniently the feature of installing, enhancing productivity.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of link, is characterized in that, described link comprises:
-regular polygon cylinder top, connects the first cylindrical perforations in it;
-top packing ring, described top packing ring is flat cylindrical body, its diameter be more than or equal to described regular polygon cylinder to angular diameter, the central shaft of described top packing ring and described regular polygon cylinder is coaxial and be positioned at the upper surface of described regular polygon cylinder, described top packing ring has central opening, described central opening and described the first cylindrical perforations are coaxially arranged
-cylindrical body bottom, the outer diameter of described cylindrical body bottom is less than or equal to the opposite side diameter of described regular polygon cylinder, described cylindrical body bottom is positioned at the lower surface of described regular polygon cylinder, in described cylindrical body bottom, second connects cylindrical perforations, described the second cylindrical hole and described the first cylindrical hole coaxially arrange, and are provided with internal thread in described the second cylindrical perforations;
Wherein, described regular polygon cylinder top, described top packing ring and described cylindrical body bottom are integral arrangement, and the diameter of described the first cylindrical perforations, the diameter of described central opening and the diameter of described the second cylindrical perforations are basically identical.
Technique scheme can also be in conjunction with following supplementary technology scheme:
The cross section of-described regular polygon cylinder is one that is selected from equilateral triangle, square, regular pentagon, regular hexagon, positive Heptagon, octagon.
By link described in the utility model, can on sheet metal, process the hole identical with described link regular polygon cylinder cross section, and by riveting gun by this link rivet clasp on sheet metal, thereby miscellaneous part is combined with sheet metal by being threaded of described link, greatly reduce operation easier, improved manufacturing efficiency, and because reach increases, thereby the reliability of attachment portion strengthened.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing that need to use embodiment is briefly described, apparently, accompanying drawing described below is embodiment of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain other mode of executions according to these accompanying drawings.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is elaborated.
According to embodiment of the present utility model, Fig. 1 to 3 shows the link 1 in original state, and it comprises top packing ring 11, regular hexagon cylinder top 12 and cylindrical body bottom 13.Wherein, in regular hexagon cylinder top 12, connect the first cylindrical perforations; Top packing ring 11 is flat cylindrical body, and its diameter be more than or equal to regular hexagon cylinder top 12 cross sections to angular diameter, the central shaft on top packing ring 11 and regular hexagon cylinder top is coaxial and be positioned at the upper surface on regular hexagon cylinder top 12, top packing ring 11 has central opening, and this central opening and the first cylindrical perforations coaxially arranged; The outer diameter of cylindrical body bottom 13 is less than or equal to the opposite side diameter of positive six polygonal cylinder top 12 cross sections, cylindrical body bottom 13 is positioned at the lower surface on regular hexagon cylinder top 12, in cylindrical body bottom 13, connect the second cylindrical perforations, the second cylindrical perforations and the first cylindrical perforations coaxially arrange.In addition, regular hexagon cylinder top 12, top packing ring 11 and cylindrical body bottom 13 are an entirety, and the diameter of the first cylindrical perforations, the diameter of described central opening and the diameter of described the second cylindrical perforations are basically identical.And be provided with internal thread in the first cylindrical perforations.
Fig. 7 shows according to the link 1 of above-described embodiment and is applied to the erection drawing on electric bedstead, comprising bedstead 2 and cabinet base 3.Bedstead 2 is provided with the regular hexagon through hole matching with the cross section on the regular hexagon cylinder top 12 of link 1.By the effect of riveting gun, make the link 1 of original state be deformed into the link 1 of installment state, as shown in Fig. 4 ~ 6.Wherein, the regular hexagon main body top 12 of link 1, owing to being subject to the pulling force of riveting gun, has produced ring-type deformable body 14, thereby top packing ring 11 and the ring-type deformable body 14 of bedstead 2 connected pieces 1 are clamped, thereby link 1 is anchored on bedstead 2.The part that is threaded on cabinet base 3 matches with the internal thread being provided with in the first cylindrical perforations, thereby cabinet base 3 is fixed on bedstead 2.
Although the utility model illustrates and illustrates at this, but to those skilled in the art clearly, as long as do not depart from purport of the present invention, can make a little different modifications, increase, replace etc., for example regular hexagon cylinder top is changed into other regular polygon cylinders such as square cylinder, regular pentagon cylinder, this all belongs to the interest field of the present utility model defining in following claim.
