Referring to fig. 1, a non-metal insert nut, comprising: insert 1 and nut base 2.

The material of the insert 1 can be deformed by extrusion, which is subsequently used to mount the insert 1 to the nut base 2, and which is also used to screw the smooth inner wall of the insert 1 when the bolt is mated with the nut.

Materials commonly used in connection with existing inserts 1, such as nylon, fiberglass, plastic, resin, and the like. Alternatively, the material of the insert 1 of the present utility model is nylon.

Referring to fig. 3 and 5, the insert 1 includes: a first annular portion 1-1, a second annular portion 1-2 and a plurality of connecting portions 1-3. The first ends of the plurality of connecting parts 1-3 are uniformly connected with the first annular part 1-1, and the second ends of the plurality of connecting parts are uniformly connected with the second annular part 1-2, namely the whole insert 1 is integrally formed through a corresponding die.

The annular inner wall of the first annular portion 1-1 is located outside the inner walls of the plurality of connecting portions 1-3, and correspondingly, a part of the inner wall on the first end of the connecting portion 1-3 is inclined as a transition portion 1-3A.

The annular outer wall of the first annular portion 1-1 is also located outside the outer walls of the plurality of connecting portions 1-3, forming a circle of first protruding portions 1-1A. The first excess 1-1A is used for subsequent connection with the nut base body 2.

For the second annular portion 1-2, optionally, a first arrangement is: with reference to the first annular portion 1-1, the annular outer wall of the second annular portion 1-2 is also located outside the outer walls of the plurality of connecting portions 1-3, forming a circle of second excess portions 1-2A. Optionally, a second setting: the annular outer wall of the second annular part 1-2 coincides with the outer walls of a plurality of said connecting parts 1-3. Compared with the first setting, the insert 1 under the second setting is more convenient for setting the mould.

Referring to fig. 6, the nut base 2 is provided with a through hole 2A, and the through hole 2A sequentially includes: a first connection portion 2A-1, a threaded portion 2A-2 and a second connection portion 2A-3.

The inner wall of the first connecting part 2A-1 is provided with an annular first clamping groove 2B, and the first clamping groove 2B is used for clamping in the first exceeding part 1-1A.

The inner wall of the threaded portion 2A-2 is provided with a plurality of axial grooves 2C, the grooves 2C are communicated with the first connecting portion 2A-1 and the second connecting portion 2A-3, namely, the inner diameters of the first connecting portion 2A-1 and the second connecting portion 2A-3 are larger than those of the threaded portion 2A-2, a first annular end face 2A-2A and a second annular end face 2A-2B are formed at two ends of the threaded portion 2A-2, and two ends of the grooves 2C penetrate through the first annular end face 2A-2A and the second annular end face 2A-2B respectively. The number of the grooves 2C is the same as that of the connecting parts 1-3, and the grooves are used for clamping in the connecting parts 1-3.

The second connecting portion 2A-3 is used to fix the second annular portion 1-2.

Referring to fig. 2 and 3, based on the first arrangement of the second annular portion 1-2, an annular second clamping groove 2D is formed in the inner wall of the second connecting portion 2A-3, and the second clamping groove 2D is used for clamping in the second beyond portion 1-2A. Thus, by deforming by pressing, the first annular portion 1-1 and the second annular portion 1-2 are recessed together, reducing the outer edge size of the entirety of the insert 1 portion, inserted into the through hole 2A of the nut base 2; the position of the insert 1 is adjusted, so that the insert 1 is restored, the first exceeding part 1-1A is clamped into the first clamping groove 2B, the plurality of connecting parts 1-3 enter the plurality of notch grooves 2C, and the second exceeding part 1-2A is clamped into the second clamping groove 2D.

Referring to fig. 4, 5 and 6, the second connecting portion 2A-3 is a ring of press deformed layers based on the second arrangement of the second annular portion 1-2. Thus, by the press deformation, the insert 1 is partially recessed inward, the overall outer edge size is reduced, and the insert is inserted into the through hole 2A of the nut base 2; the position of the insert 1 is adjusted, so that the insert 1 is restored, the first exceeding part 1-1A is clamped into the first clamping groove 2B, the plurality of connecting parts 1-3 enter the plurality of notch grooves 2C, and the second annular part 1-2 is attached to the inner wall of the second connecting part 2A-3; the end surface of the second connecting portion 2A-3 far from the nut base body 2 exceeds the second annular portion 1-2, the exceeding portion is deformed into an annular bent portion 2A-3A by punching, and the second annular portion 1-2 is compressed by matching with the second annular end surface 2A-2B.

Referring to fig. 7, the number of the plurality of connection portions 1-3 is three. In the above-described "the first annular portion 1-1 and the second annular portion 1-2 are recessed together by the press deformation", the connection position of the first annular portion 1-1 and the connection portion 1-3, the connection position of the second annular portion 1-2 and the connection portion 1-3 is not easily deformed. Since the first annular portion 1-1 and the second annular portion 1-2 are recessed together, the first annular portion 1-1 will be described as an example. When the number of the connecting parts 1-3 is three, the first annular part 1-1 can be divided into three first arc-shaped parts 3, and the middle position of one first arc-shaped part 3 is pressed inwards to drive the other two first arc-shaped parts 3 to deform.

Referring to fig. 1 and 8, the nut may alternatively be devoid of the hexagonal flange face 4. Alternatively, the nut may be provided with a hexagonal flange surface 4, and specifically, the hexagonal flange surface 4 is integrally provided at an end of the nut base 2 corresponding to the first connecting portion 2A-1.

When the bolt and the nut are matched, the first connecting part 2A-1 starts to be screwed in, and the annular inner wall of the first annular part 1-1 is positioned at the outer side of the inner walls of the plurality of connecting parts 1-3, and correspondingly, part of the inner walls on the first end of the connecting part 1-3 are inclined, namely, the bolt is singly connected with the thread part 2A-2 in a threaded manner; then, after contacting the inner wall of the connecting part 1-3, the connecting part is connected with the screw thread part 2A-2 and the inner wall of the connecting part 1-3 by screw threads simultaneously, so that screw threads are generated on the smooth inner wall of the connecting part 1-3; finally, the bolt is connected with the second annular part 1-2, so that threads are also formed on the smooth inner wall of the second annular part 1-2.
