Abstract
The utility model discloses a nut which comprises a nut body (1); a convex pan head (2) with teeth for rotation prevention is further arranged at one end of the nut body (1); and the outer diameter of the convex pan head (2) with the teeth is larger than that of the nut body (1). The convex pan head (2) with the teeth and the nut body (1) are integrally formed. Plating layers are arranged on the surfaces of the convex pan head (2) with the teeth and the nut body (1). With the nut, position adjustment can be carried out on a part assembly with an internal thread structure; furthermore, the nut is easy for processing and convenient for operation.
Description
Technical field
The utility model relates to fastening piece, specifically is a kind of nut.
Background technique
Carrying out the position adjustment by the rotation of nut is one of present machine part assembling conventional design function, thick fine setting means such as the spiral chute slip adjustment that the mode of nut adjustment at present adopts mostly, screw thread rotation adjustment, gear hobbing engagement adjustment, characteristics are to rotate the external thread piece that drives cooperation by nut to move axially.But the adjustment narrow limitation of this nut is very big, and nut must design at the outer surface of machine and near apart from operator, makes it easy to operate, even otherwise adopted above-mentioned adjustment structure also can't operate.
In some cases, the component assembly that has female thread structure need design locomotive function, so just can't adopt above-mentioned adjustment mode, have the component assembly of female thread structure simultaneously because structure is big, complex-shaped, make trouble relatively, be difficult to as single manufacturing, it can only be designed to builtup member like this, nut is installed in component assembly again.But present nut does not have circumferential position structure, can't make the component assembly of female thread structure carry out the position adjustment.
The model utility content
The technical problems to be solved in the utility model is, provides a kind of component assembly that has female thread structure that can make to carry out position adjustment and easy processing, easy to operate nut.
The technical solution of the utility model is, a kind of nut with following structure is provided, and comprises nut body, and an end of described nut body also is provided with the protruding coiled hair of band tooth that is used for anti-rotation, and the external diameter of the protruding coiled hair of described band tooth is greater than the external diameter of nut body.
The utility model compared with prior art, have the following advantages: because an end of described nut body also is provided with the protruding coiled hair of band tooth that is used for anti-rotation, the nut body of the protruding coiled hair of this band tooth cooperates with corresponding external thread piece, carry out anti-rotation and riveted location by the internal tooth that cooperates of being with the protruding coiled hair of tooth with coupled, by twisting and adjust the link external thread piece of fitting of round nut, can realize the position regulation of nut and then drive coupling moving, to satisfy the adjustment position functions demand that solves one-piece element, can solve the complex component assembly that has female thread structure has locomotive function design needs, and easy processing, easy to operate.
As improvement, protruding coiled hair of described band tooth and nut body are made of one piece, and be easy to process.
As improvement, the surface of protruding coiled hair of described band tooth and nut body is provided with coating, and rust-proof effect is good.
Description of drawings
Accompanying drawing 1 is the main TV structure schematic representation of nut of the present utility model.
Accompanying drawing 2 is the right TV structure schematic representation of nut of the present utility model.
As shown in the figure: 1, nut body, 2, band tooth protruding coiled hair.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, nut of the present utility model comprises nut body 1, and an end of described nut body 1 also is provided with the protruding coiled hair 2 of the band tooth that is used for anti-rotation, and the external diameter of the protruding coiled hair 2 of described band tooth is greater than the external diameter of nut body 1.
The protruding coiled hair 2 of described band tooth is made of one piece with nut body 1, can adopt cold-heading molding to process.
The protruding coiled hair 2 of described band tooth is provided with coating with the surface of nut body 1.
Claims (3)
1. a nut comprises nut body (1), it is characterized in that: an end of described nut body (1) also is provided with the protruding coiled hair of band tooth (2) that is used for anti-rotation, and the external diameter of the protruding coiled hair of described band tooth (2) is greater than the external diameter of nut body (1).
2. nut according to claim 1 is characterized in that: the protruding coiled hair of described band tooth (2) is made of one piece with nut body (1).
