Abstract

In summary, the nut to be invented has a body part with a hexagonal shape or a square octagonal shape, and the thread part is a separate object in the body part, but it is used in combination with the external shape. When forming the inclined surface and moving on this inclined surface, the hole in which the bolt enters becomes larger and smaller, and when it is assembled, it solves the advantage that it should not be caught or caught by the screw. In this way, the combined nut moves the binding screw part to some extent to enlarge the hole, and the diameter of the nut that is larger than the outer diameter of the bolt enters the bolt to the last closing side without any resistance. It is completely tightened.

Description

Binding Nut

The present invention has been invented in the field of machinery in the field of the industrial field of the present invention for the purpose of using the female screw of the screw, that is, easily and quickly and efficiently, the screw can be moved back and forth in a structure in which the nut and the main body is separated and coupled It was developed for the purpose of fastening screws by using structure and movement.

Generally, a screw is divided into a bolt and a nut, and a general nut is usually hexagonal, and its parallel surface is turned by a spanner. Special ones include butterfly nuts with a four-member, eight-member, or butterfly-shaped locking knob. These nuts are fastened by screwing together with the thread of the external thread when tightening the screw, and it takes a long time in the situation where the bolt is long or the working condition is not easy.

In the prior art as described above, the problem is that the bolt is invisible due to the working conditions or the movement of the hand or the tool is difficult, and the bolt is too long to take a long time to tighten the nut. This is to reduce the amount of time by simply tightening the nut, increasing the efficiency of work and improving the performance.

The present invention is divided into the nut main body and the binding screw in the nut, and the main body is as described in the background art, but the inside of the nut to make the hole of the screw given the inclination angle by calculating the acid, thickness and width of the nut at an appropriate ratio, Is combined with the main body, but moves in a flow form instead of a full binding so that the bolt is bound by the inclined structure of the main body and the movement of the binding unit.

Increasing the overall efficiency of the work It is easy and quick to work, reducing the time and tightening without loosening in vibration or jungle

The drawings below are basically selected parts of the projection projected by trigonometry where necessary, and the nut itself is so simple that it will be easy to understand the structure of the nut.
Representative diagrams are stereoscopic and assembled stereoscopic diagrams of each component required for nut construction.
Fig. 1 is a main body part (projection, cross-sectional view and stereoscopic view of the shaft hole stopper and the main body part to be combined with the main body part).
Fig. 2 shows the binding screw part (the projection and the three-dimensional drawing of the ring and the assembly drawing, which do not disturb when the binding screw part is assembled like the assembly three-dimensional drawing).
(Figure 3) is an assembly diagram with a bolt (three-dimensional diagram when the bolt inside the screw moves after assembling with one nut and when the bolt is combined.)

The present invention is largely divided into a main body portion of the nut and a screw binding screw portion, and the inside of the main body is inclined between the holes and the holes because the sizes of both holes 102 and 103 in the left side view and the right side view of the main body drawing (Fig. 1) are respectively different. It is a hole forming an angle 100 and a groove 101 is formed on the wall forming the inclination angle, and this groove is a binding screw part (Fig. 2) to move forward and backward in a diagonal direction on the groove 101 and the inclined surface 100. The shape of the binding screw portion (Fig. 2) is inclined as shown in the front view and the top view of Fig. 2, and the shaft 105 is attached to the upper portion, and the shaft 105 is only half of the groove 101. The reason is that the binding screw part (Fig. 2) gives a space for moving inside the main body (Fig. 1). It is also divided into several parts, and the combination of the main body part (Fig. 1) and the binding screw part (Fig. 2) is shown in the representative view. As shown in the figure above, it is inserted into the small hole 102 from the large hole 103 side. After opening, the hole stopper in Fig. 1 blocks the rear hole to prevent the binding screw part from flowing out.Representative view shows the groove 107 at the left end in the front view of the binding screw part (Fig. 2). To lock the screw ring and this groove 107 to the nut assembled in the bolt assembly as shown in (3). When the bolt 106 is pushed in, the binding screw (Fig. 2) is pushed in, and the hole is enlarged by the inclined surface 100, the bolt 106 enters the hole wider than the bolt 106, and the nut is extended to the last end. Push in and tighten until the nut is tightened. When the fastening direction of the fastening screw part (Fig. 2) caught by the thread of the bolt 106 goes to the front when tightening the nut, the nut main body part (Fig. 1) is pushed backwards, pushing the inclined surfaces 100 to each other and Has the feature of tightening the bolts further

      It can be used anywhere the nut enters, and it seems to be easier to use when a large force is used or when a large nut is used.

Claims (1)

There is a nut body part (Fig. 1) having an inclined hole 100 and a groove 101 capable of guiding an axis on the inclined surface of the inclined hole, and the holes 101 have a binding screw part (Fig. 2). Nut body part which does not fall out
In addition, the shaft 105 enters the groove 101 and the binding screw portion (FIG. 2) connected to the shaft 105 has a structure moving along the groove 101 and the inclined surface 100 in the main body portion (FIG. 1). Fastening thread
In addition, when the combined nut is completely tightened to the bolt 106, the direction of the binding screw portion (Fig. 2) caught by the thread of the bolt 106 and the direction of the nut body portion (Fig. 1) are pushed in opposite directions, and the inclined surface 100 is mutually pushed. Binding nut with the characteristic of tightening the bolt more tightly while pushing
