Abstract
The utility model discloses a connecting nut which comprises a nut body with internal threads; and a positioning bump is arranged in the middle of the inner wall of the nut body. The utility model has the advantages of simple structure, accurate positioning, easy processing and lower cost. The positioning bump on the inner wall of the connecting nut ensures that the joint of two link levers is in any position required (generally in the center of the connecting nut to ensure uniform stress). Particularly the common split wall passing screw used in the building and construction industry is generally positioned by welding a positioning sleeve on the screw body, which is troublesome in processing and high in cost. However, if the connecting nut provided by the utility model is adopted, the problem of accurate positioning can be solved only by the positioning bump on the inner wall of the nut body; and in addition, not only the structure of the split wall passing screw becomes simpler and the production cost becomes lower, but also the labor intensity is reduced and the working efficiency is improved.
Description
Technical field
The utility model relates to nut, especially relates to a kind of attaching nut that two screw rods are connected as a single entity.
Background technique
In multiple industries such as mechanical industry, construction industry, many occasions need be linked to be the many bodies of rod stock and use, the simplest connection set commonly used has been exactly the attaching nut, soon need the end outer circumferential face difference threading of two bars of connection, and utilize the attaching nut that it is connected as a single entity.But common nut is not owing to there is locating function, and the binding site of two bars can not guarantee to be in attaching nut's central position, causes two bar discontinuity after the connection; For solving the problem of accurate location, some attaching nuts adopt the structure of half right-hand thread, half left-hand thread, also have some attaching nuts to adopt the method for wearing locating stud, but the attaching nut of said structure process trouble, and cost is higher, is unfavorable for promoting.
The model utility content
The purpose of this utility model is to provide a kind of simple in structure, accurate positioning, lower-cost attaching nut.
For achieving the above object, the utility model can be taked following technical proposals:
Attaching nut described in the utility model comprises the nut body that has internal thread, and the inwall of described nut body is provided with positioning convex point.
Described positioning convex point is arranged on the medium position of nut body.
That advantage of the present utility model is is simple in structure, accurate positioning, be suitable for processing, and cost is lower.Positioning convex point on attaching nut's inwall can guarantee that the binding site of two connecting rods is in needed any position (stressed evenly for assurance, as generally to be in attaching nut's central position).The screw rod split type through walls that particularly construction industry is commonly used, all be that the welding setting sleeve is located on the body of rod at ordinary times, the processing trouble, the cost height, if after adopting attaching nut of the present utility model, the positioning convex point on the nut body inwall can solve the problem of accurate location, not only make the structure of split type screw rod through walls simpler, cost of production is lower, has also reduced working strength of workers, has improved working efficiency.
Description of drawings
Fig. 1 is that master of the present utility model cuts open schematic representation.
Fig. 2 is the right elevation of Fig. 1.
Embodiment
As shown in Figure 1, 2, attaching nut described in the utility model comprises the nut body 1 that has internal thread, and the inwall of described nut body 1 is provided with positioning convex point 2; Stressed evenly for guaranteeing continuous two bars, described positioning convex point 2 is arranged on the medium position of nut body 1.
After the nut body completion of processing of common process with the attaching nut, put into the punch press frock, drift presses down, and impulse force is passed to inwall from the external wall of attaching nut, forms positioning convex point, and whole course of working is simple, and the efficient height is easily up to standard.
Claims (2)
1. an attaching nut comprises the nut body (1) that has internal thread, and it is characterized in that: the inwall of described nut body (1) is provided with positioning convex point (2).
2. attaching nut according to claim 1 is characterized in that: described positioning convex point (2) is arranged on the medium position of nut body (1).
