Description
Technical field
The utility model relates to nut, specifically refers to a kind of new type nut.
Background technique
As everyone knows, nut is exactly nut, be screwed in bolt or screw rod together be used for the part that plays the role of fastening.In Assembly of the parts, people often adopt locking plate, pin, distortion screw thread, nylon embedded piece, self-locking nut or use chemical glue mull technique, even solve the problem that gets loose of threaded fastener with measures such as multiple nut screwing clampings, but nut to be connected with bolt or screw rod as fastening piece and easily to produce problems such as getting loose.Adopt above-mentioned measure, due to the shortcoming that it cannot overcome, the locking plate, technique or the material cost that there is specific function as increased, and locking function is for once effective, can not reuse, the problem that gets loose of threaded fastener fails the solution that obtains always to a certain extent, on the other hand, the mould structure of conventional nut is complicated, during die sinking, needs rotating stripping demoulding, cost is high, and volume production manufacturing efficiency is low, for a long time, this problem also fails the solution that obtains.
Model utility content
The purpose of this utility model is to provide that a kind of structure is simple, cost is low, efficiency is high, the new type nut of stable connection and long service life.
The utility model can be achieved through the following technical solutions:
A kind of new type nut, comprise metal shell and built-in cylinder, described metal shell inside is the step hole of hollow, the aperture of step hole is up-small and down-big, the upper end of step hole is provided with the first thread and the second thread, first thread and the second thread are the thread misplacing and do not connect, namely be that the first thread is different from the height of the second thread, and gap is left respectively in the two ends of the two ends of the first thread and the second thread, first thread is not connected with the second thread, built-in cylinder is studded with in described metal shell, the external diameter size of described built-in cylinder matches with the lower part pore size of step hole, the inner circumference of built-in cylinder is provided with equally distributed some convex tendons, the outer end of some convex tendons is the arc surface coaxial with inner peripheral surface, this Novel nut structure is simple, cost is low, efficiency is high, stable connection, constant product quality, long service life.
Further, described convex tendon is eight, and eight convex tendons are evenly distributed on the inner circumference of built-in cylinder.
Further, in order to make when bolt screws in nut, convex tendon can better hold bolt tightly, and described convex tendon protrudes built-in cylinder inner circumference 0.1 ~ 0.15mm.
Further, the diameter of described convex tendon is less than the large footpath of thread of bolt.
Further, the upper end portion of described step hole is provided with chamfering.
Further, described built-in cylinder is made up of plastic material, also can be made up of other plastic material.
Further, in order to increase the rigidity of metal shell, described metal shell selects steel to make.
The utility model nut has following beneficial effect:
1, cost is low, efficiency is high, constant product quality, the shell that the utility model nut adopts steel to make, the thread that inside, shell upper end is provided with two button dislocation and does not connect, when mold, without rotating stripping demoulding, the easy structure of mould, cost is low, and manufacturing efficiency is improve in batch production, ensure that quality of product simultaneously;
2, stable connection, long service life, the thread that inside, shell upper end is provided with two button dislocation and does not connect, built-in cylinder interior is provided with equally distributed eight convex tendons, make bolt when screwing in nut by thread, convex tendon can hold bolt tightly, makes nut and bolt be in tight engagement all the time, stable connection, avoid the situation that gets loose to occur, increase working life;
3, structure is simple, and manufacturing efficiency is high, and metal shell adds the structure of the built-in cylinder of interior edge, structure is simple, the thread that inside, shell upper end is provided with two button dislocation and does not connect, when mold, without rotating stripping demoulding, the easy structure of mould, in addition, built-in cylinder is also easier in die sinking, simplify mould structure, improve manufacturing efficiency, meanwhile, also reduce cost.
