Description

The utility model relates to a hand tool, namely a tool for screwing and unscrewing.

Screw and unscrew screws and nuts with wrenches. In the absence of free access to the screw heads and nuts from the sides, socket wrenches or interchangeable heads with a grip on all faces are used. Socket wrenches are known with holes for a crank or mounting blade, as well as with an internal or external connecting square. [12].

A well-known insert for mounting and dismounting a fastener with a threaded connection (RF Patent for utility model No. 174573, IPC V25V 23/00, V23R 19/06, published 10/31/2017, bull. No. 31), containing a cylindrical body with a through axial hole and vertical protrusions uniformly distributed in its lower part to capture the surface of the fastener, while along the entire height of the cylindrical body a vertical cutout is made, combined with a through axial hole, and a blind hole is made on the upper surface of the cylindrical body, while the body is made with the possibility of fixing the side surface in the mounting tool.

A universal end head is known (RF Patent for utility model No. 57185, IPC V25V 13/00, published 10.10.2006, bull. No. 28), containing a housing that includes at least two parts located on the same axis, while one, first, part is made solid and has a central hole, and the other, second, part is made essentially cylindrical and hollow, while the cross section of the first part has the shape of a polygon, and the said second part has on its inner surface a plurality of longitudinal teeth having a distance between their bases, while the height of the teeth is chosen to ensure interaction with the outer surface of the fasteners when they are screwed in / unscrewed.

A self-adjusting connector is known (U.S. Utility Model Patent No. 6467379 B1 US, IPC B25B 13/06, published 10/22/2002), which is an adjustable socket for mounting mounting protrusions of various sizes, such as hex nuts. Includes a hollow-bent socket body and a spring-loaded plate that pushes the nested bushings into the socket opening. The locking member holds the outer sleeve, and the offset lower sleeve lugs form interchangeable lugs for holding the inner sleeves. Pairs of magnetic strips located between the sleeves are integrated with them to create magnetic pairs. During operation of the utility model, the inner sleeve collides with one or more smaller sleeves and breaks the magnetic connection between the largest of the smaller sleeves and the next largest sleeve. The magnetic connections between the larger bushings are maintained while the smaller bushings move down. Thus, by holding the smaller of the bushings in their original position, the shape of the slanted holes can be chosen to accommodate the projections of the fasteners of various shapes.

Closest to the claimed technical solution (prototype) is a nozzle for unscrewing-tightening the plug of the driving wheel of the undercarriage of armored vehicles. (Patent of the Russian Federation for a utility model No. 173834, IPC V25V 23/00, B62D 55/32, published on September 13, 2017, bull. No. 26), which is a monolithic body, inside which along the longitudinal axis along the inner circumference are formed slots through the bushing, with on one side, the bushing is made with the possibility of covering the drive wheel plug, the teeth of which are made with an involute profile, and their number corresponds to the number of teeth of the drive wheel plug. On the opposite side, the nozzle body is made in the form of a bushing, inside of which a rectangular groove is formed for installing a transitional square of the torque amplifier in it, and a groove is made on the outer surface for installing a rubber ring of a locking pin in it for the possibility of fastening a driving tool.

The disadvantage of the presented analogues and the prototype is the impossibility of their use with existing socket wrenches with holes for the knob or mounting blade. In addition, a significant disadvantage is the high cost of manufacturing keys and heads with a connecting square with a jaw size of more than 75 mm.

The technical result of the claimed technical solution is to expand the capabilities of the prototype through the use of socket wrenches with holes for the wrench in conjunction with torque wrenches and wrenches of various designs, as well as the ability to control the tightening torque of threaded connections when using socket wrenches with holes for the wrench and not having a connecting square.

The technical result is achieved due to the fact that the adapter for the socket wrench with holes for the knob, the end part of which is made in the form of a sleeve, inside which a rectangular groove is formed for installing a connecting square in it, the adapter is made in the form of a welded part and its cylindrical part has two mounting holes through which, with the help of a connecting bolt and nut, it is mounted on a socket wrench, and the junction of the face and cylindrical parts of the adapter has a protrusion.

The presence of new distinctive essential features indicates the compliance of the claimed utility model with the criterion of patentability "novelty".

The claimed technical solution can be made from known materials using known means, which indicates the compliance of the claimed utility model with the patentability criterion "industrial applicability".

The claimed technical solution is illustrated by the following drawings: figure 1 - sleeve connecting square (top view), figure 2 - adapter for socket wrench with holes for the knob (in section).

The adapter for the socket wrench with holes for the knob consists of two parts: a cylindrical part 4 (figure 2) and an end part 3 (figure 1, 2) with a sleeve 1, inside of which a rectangular groove 2 is formed to install a connecting square in it. On top of the cylindrical part 4 is laid the end part 3 of a larger diameter than the cylindrical part. The distance between the circumference of the cylindrical part and the end part forms a protrusion 6 (figure 2). The protrusion ensures the immobility of the connection between the adapter and the socket wrench. The connection of the cylindrical 4 and the end part 3 provides a welding seam. The cylindrical part 4 has two mounting holes 5 located on the same axis.

Controlling the required initial tightening force is essential to the strength of screws and nuts. By connecting the socket wrench with a torque wrench and nutrunners via a square drive, it is possible to control the tightening torque of threaded connections. Tightening torque control will ensure the reliability of the threaded connection under variable loads and the screwing of threaded connections with the necessary force, in accordance with the requirements of regulatory and technical documentation. [1,3].

The claimed utility model works as follows.

The torque required for screwing or unscrewing the nut is generated by a torque wrench or wrench and transmitted to the socket wrench through the sleeve 1 of the connecting square of the adapter, which has a rectangular groove 2 and is permanently connected to the end part of the adapter 3 and the cylindrical part of the adapter 4. The adapter is mounted on the socket wrench with the help of a connecting bolt and nut through the mounting holes 5, the protrusion 6 keeps the adapter from transverse displacement relative to the socket wrench.

Thus, when a torque is applied to the adapter, the nut is screwed or unscrewed together with torque wrenches and wrenches of various designs, the tightening torque of threaded connections is controlled, which ensures the achievement of a technical result.
