RU194390U1 - KEY FOR POSITIONING FASTENING PRODUCTS WHEN SCREWING AND UNFORMING FASTENING PRODUCTS - Google Patents

Abstract

The utility model relates to keys for positioning a fastener when screwing and unscrewing a fastener. The key contains a hollow cylindrical body, on the working side of which internal faces are made for interaction with the faces of the fastener, and a central part of a cylindrical shape, on the working side of which internal faces are made for interaction with the faces of the fastener, coaxially inserted into the body with limited axial movement and free rotation of the housing and the Central part relative to each other. The technical result is to ensure that the adjusting screw is screwed in fully, it is turned off at an angle determined by the requirements of the design documentation, the adjustment screw is held in position when tightening the lock nut, and the lock nut is tightened. 6 c.p. f-ly, 3 ill.

Description

The inventive utility model relates to hand tools for screwing / unscrewing fasteners having faces for interacting with the tool, positioning them in the desired position relative to each other with the possibility of independent and / or simultaneous impact on two fasteners and can be used in various industries.

The prior art design

universal socket head [RF patent for utility model No. 178312, published March 29, 2018]. A universal end head comprising a housing including two parts located on the same axis, wherein the first part is solid and has a central opening in the form of a polygon - a “connecting square”, and the second part is made essentially cylindrical and hollow having the shape of a regular hexagon, moreover, on its inner surface, the second part has a hexagon of maximum size, and inside it movable hollow hexagons with free movement relative to each other and the body, movable lye hexahedron capable when pressed away inwards by a height of the screw head or nut and returns to its original position under the action of an elastic material of each hollow hexagon.

This design is selected as a prototype for the claimed utility model.

The technical problem of the above construction is the impossibility of affecting fasteners having a different number of faces designed to interact with the tool, as well as the simultaneous and independent impact on fasteners.

The technical result, to which the claimed technical solution is directed, is to ensure that the fastener, for example the adjusting screw, is screwed all the way, it is turned away at an angle determined by the requirements of the design documentation, the fastener is held in the required position while the other fastener is screwed, for example, a lock nut At the same time, fasteners can have a different number of faces designed to interact with the tool.

The essence of the utility model is illustrated by drawings, where:

FIG. 1 - The key for positioning the fastener when screwing in and out the fastener in the position to act on the adjustment screw;

FIG. 2 - The key for positioning the fastener when screwing in and out the fastener in the position to act on the adjusting screw and lock nut;

FIG. 3 - Key for positioning the fastener when screwing the fastener in and out (side view).

The technical result is achieved by the fact that the key for positioning the fastener when screwing in and unscrewing the fastener contains a hollow body 1 (Fig. 1) of a cylindrical shape, on the working side of which there are internal faces A (Fig. 3) for interacting with the faces of the fastener; and the central part 2 (Fig. 1), of cylindrical shape, on the working side, the inner faces B (Fig. 3) for interacting with the faces of the fastener, coaxially inserted into the housing with the possibility of limited axial movement and free rotation of the housing and the central part relative to each other ; the value of the axial displacement B (Fig. 2) provides both independent and simultaneous action on the fasteners in the extreme positions of the axial displacement of the keys relative to their relative position.

The technical result from the application of the proposed utility model is to ensure that the adjusting screw is screwed in fully, it is turned away at an angle determined by the requirements of the design documentation, the adjustment screw is held in position when tightening the lock nut and tightening the lock nut.

Currently, the claimed utility model has developed design documentation, a special key sample is made and successfully used.

Claims (7)

1. A key for positioning the fastener when screwing and unscrewing the fastener, comprising a hollow cylindrical body, on the working side of which there are internal faces for interacting with the faces of the fastener, and a central part of a cylindrical shape, on the working side of which there are internal faces for interacting with the edges of the fastener coaxially inserted into the housing with the possibility of limited axial movement and free rotation of the housing and the central part no one another. 2. The key according to claim 1, characterized in that on the working side of the housing there are six faces. 3. The key according to claim 1, characterized in that on the working side of the housing there are twelve symmetrically intersecting faces. 4. The key according to claim 1, characterized in that four faces are made on the working side of the central part. 5. The key according to claim 1, characterized in that eight symmetrically intersecting faces are made on the working side of the central part. 6. The key according to claim 1, characterized in that the casing and the central part are marked, for example, risks for visual control of the angle of rotation of the central part relative to the casing. 7. The key according to p. 1, characterized in that on the working side of the housing is made outward groove.
