Description

The proposed technical solution relates to a hand tool, namely to socket wrenches for preliminary assembly of threaded joints in hard-to-reach places and can be used in various types of activities.

Known socket wrench (GOST 25787-83) containing a rod, on one end of which there is a handle, and on the other - the working part

The simple design of such a socket wrench does not allow holding the nut and washer in the throat of its working part during assembly work in hard-to-reach places, where there is no direct access to the threaded connection for mounting the washer and nut. Therefore, when assembling in hard-to-reach places, additional technological operations are required when installing fasteners (washers and nuts). As a result, the complexity of assembling threaded joints increases.

Closest to the claimed technical solution is the design of the socket wrench (MPK V25V 13/06, ed. Certificate No. 1419876, publ. 08.30.88), containing a rod, on one end of which there is a handle, and on the other - a sleeve connected to working part.

This design of the socket wrench is quite complicated, but it allows you to keep only the nut from the fasteners from the fasteners, but not the washer. And to install the washer at the assembly site, an additional technological operation is also required. This also leads to an increase in the complexity of the assembly of threaded joints.

The challenge facing the author is to create a simplified design of the socket wrench, which reduces the complexity of the assembly of threaded

connections in hard-to-reach places by ensuring the simultaneous holding in the throat of the working part of the socket wrench fasteners (washers and nuts).

The specified problem is solved as follows.

The author proposes in an end wrench containing a rod, on one end of which there is a handle, and on the other - a sleeve connected to the working part is fixed, the working part is made of elastomeric material with the possibility of holding fasteners.

The author suggests using rubber or reinforced rubber or polyurethane as an elastomeric material.

The author suggests that the outer surface of the sleeve be grooved.

The proposed implementation of the socket wrench allows you to simultaneously hold fasteners (nut and washer) in the throat of the working part of the socket wrench in any of its positions when assembling threaded joints in hard-to-reach places, thereby eliminating additional technological operation and reducing the complexity of the assembly.

The absence of additional parts in the proposed design of the socket wrench designed to hold fasteners inside the working part, and the implementation of its inner surface of a cylindrical shape makes it as simple as possible.

The execution of the outer surface of the corrugated sleeve ensures reliable fixation of the working part on it.

Figure 1 shows a General view of the socket wrench.

Figure 2 is a section aa.

In an end wrench containing a rod 1, at one end of which a sleeve 2 with a corrugated surface 3 is fixed, connected by means of a fastener 4 with a working part 5 made of elastomeric material (rubber or reinforced rubber or polyurethane), pharynx 6, which has a cylindrical shape, and at the other end of the rod 1 is a handle 7.

The proposed socket wrench work as follows.

Before assembling the threaded connection in an inaccessible place in the throat 6 of the working part 5 of elastomeric material (rubber or reinforced rubber or polyurethane), a nut and a washer are installed at the same time (not shown in Fig.). The working part 5 of elastomeric material due to its elastic strength properties tightly wraps around the nut and washer (not shown in Fig.) And keeps them from falling out in any position of the socket wrench. The socket wrench with the working part 5 is sent to the assembly place and at the same time all the elements of the threaded connection are connected. Then, turning the handle 7, screw the nut (not shown in Fig.). After this, the hands of the worker by the handle 7 pull the working part 5 of the socket wrench from the nut and washer.

Finally tighten the threaded connection with another socket wrench having a metal working part.

Thus, the proposed socket wrench has a simple design, which allows to reduce the complexity when assembling threaded joints in hard-to-reach places.
