Abstract
The utility model discloses a nut with self-locking performance. The nut comprises a nut section (1) and a self-locking head section (2), wherein the nut section (1) and the self-locking head section (2) are connected into a whole, the self-locking head section (2) is provided with closing straight grooves (3), and the inner diameter of the thread of the self-locking head section (2) is smaller than the inner diameter of the thread of the nut section (1). The common nut section and the self-locking head section are connected into a whole to form the nut, the self-locking head section is provided with the straight grooves, end ports of the self-locking head section are extruded and closed, then the diameter of the thread hole of the self-locking head section becomes smaller, when a screw is screwed in, elastic deformation of extruded end ports is achieved, the nut is in close contact with the screw, and the self-locking is achieved through the increment of the friction among threads. Compared with existing common nuts, the nut is safe and reliable to use. Compared with existing self-locking nuts, the nut is simple and has a high safety factor.
Description
Technical field
The utility model relates to a kind of nut with self-locking property, belongs to technical field of fastening.
Background technique
Since mechanical industry was come out, nut had just produced, and nut is with a long history; Become the indispensable component of mechanical industry, as widely-used invariably on the instruments such as railway, bridge, electric power, mine, aircraft, tank, automobile, but plain nut in use; Particularly under alternation vibrations and high-frequency vibration; The fastening effect of nut can weaken, thereby gets loose voluntarily, the generation accident.Institute thinks and prevents that nut from getting loose, and reduces potential safety hazard, and method commonly used at present does; The double nut back of the body is tight, increase spring washer or on nut method such as bayonet lock solve, these methods have not only increased the consumption of material; Time-consuming; And of long duration still can get loose, it is unreliable that fastening effect is appointed, and has potential safety hazard.And mostly existing self-locking nut is an end of nut is pushed, and makes its distortion form self-locking nut, but lower, the easy inefficacy of this self-locking nut safety coefficient.
Summary of the invention
The purpose of the utility model is, a kind of nut of band self-locking property simple in structure, easy to use is provided, and can overcome the deficiency of existing technology.
The technological scheme of the utility model: the nut of band self-locking property, it is made up of nut segment that is connected as a single entity and self-locking head section, on the self-locking head section, offers the closing in straight trough, and the minor diameter of thread of self-locking head section is less than the minor diameter of thread of nut segment.
The quantity of closing in straight trough is 4-8.
Compare with existing technology, the utility model is made up of plain nut section that is connected as a single entity and self-locking head section, through on the self-locking head section, offering straight trough; Then its port is pushed closing in; Its tapped hole diameter is diminished, the port generation resiliently deformable that when screw rod screws in, is extruded, thus nut is contacted with screw rod closely; Through increasing the frictional force between screw thread, form self-locking.Its use of existing relatively plain nut is more safe and reliable, and other self-locking nut is simple more relatively, safety coefficient is higher.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Embodiment: as shown in Figure 1; The nut of band self-locking property is made up of nut segment that is connected as a single entity 1 and self-locking head section 2; Self-locking head section 2 is the thin cone of wall thickness, and with the closing in straight trough 3 of line cutting process perpendicular to screw thread, the quantity of closing in straight trough 3 is 4-8 on self-locking head section 2; Method through extruding closes up self-locking head section 2 then, makes the minor diameter of thread of self-locking head section 2 less than the minor diameter of thread of nut segment 1.
Claims (2)
1. nut with self-locking property; It is made up of nut segment that is connected as a single entity (1) and self-locking head section (2); It is characterized in that: on self-locking head section (2), offer closing in straight trough (3), the minor diameter of thread of self-locking head section (2) is less than the minor diameter of thread of nut segment (1).
2. the nut of band self-locking property according to claim 1 is characterized in that: the quantity of closing in straight trough (3) is 4-8.
