Description

one

The invention relates to mechanical engineering.

A locking device is known that contains threaded elements of type 1, for example, a bolt and a nut, bound by a wire, a part of which is placed in a groove of a workpiece to be joined, made next to the threaded elements, while the part of the wire has a spring element that provides torque, counteracting unscrewing

This device is difficult to manufacture and install.

The closest to the invention in technical essence and the achieved result is a locking device containing threaded elements, such as a bolt and a nut, bound by a wire, a part of which is located by the head of the bolt or by a nut to the connected hoist.

This device is simpler, but can only be used for joining parts made of materials that allow for the forceful insertion of wire in their surface.

for example wood, which limits the scope. In addition, the reliability of the locking device is not great, since the wire can crush the wood and extend beyond the head of the bolt and nut.

In order to expand the field of application and increase the reliability of locking, a straight groove is made on the surface of the joint to be connected, which is tangentially to the bolt hole and has a length greater than the diameter of the described circumference of the head of the bolt or nut.

FIG. Figure 1 shows the options for hexagonal nut locking; in fig. 2 shows a line AA, FIG. Li; FIG. 3 — options for locking the hex bolt; in fig. 4 - options for locking the screw with a screwdriver head.

Binding nuts can be made on the; In the embodiment illustrated in FIG. 1, for which the wire stopper 1 is inserted into the groove of the fastened part (base) 2, and the nut 3 is tightened onto the threaded rod 4. The tie of the hexagonal bolt is shown in FIG. 3. The wrapping of the cylinder spline head is shown in FIG. four

To securely wire, ftwtvto needs to choose thicker | What are used in practice? At present, steel wire with a cross-section area of 0.5 mm or 0.8 mm is used. A wire of such thickness is easy to cross and break. Therefore, a stronger wire is needed for tight wiring, creating a strong wire clip — a wire stop.

The diameter of the threaded hole (rod-sh |) 10 mm corresponds to a wire diameter of 1 (5 mm, diameter of 20 mm - 3 mm, etc.). The expediency of using steel and soft wire is dictated by the need for tight wiring (without gaps), ensure that your better locking.
