RU193130U1 - MANUAL DEVICE FOR TIGHTENING AND RELAXING THREADED CONNECTIONS WITH A DYNOMETRIC KEY - Google Patents

Abstract

The invention relates to devices designed to tighten and loosen threaded connections using a torque wrench. The device comprises a housing configured for rotation, as well as a cap head formed on the housing, formed by a plurality of channels and configured to accommodate a threaded connection in the head, and an opening located parallel to the cap head, configured to accommodate a torque wrench in the hole in the longitudinal direction to the axis of the device for applying torque. Using the proposed device allows you to effectively tighten and loosen threaded connections using a torque wrench in hard to reach places.

Description

The utility model relates to devices for tightening and loosening threaded connections using a torque wrench.

Known and widely used for tightening threaded connections of the device, which are adapters, nozzles, wrenches, as a rule, having a tool input unit, in this case, under a torque wrench and a working head.

A device is known for loosening such fasteners as a nut, bolt, screw. The device comprises a support lever, includes a shaft that is rotatably mounted, at least one torque application lever located on said shaft to provide transmission of torque to this shaft, and at least one end head. The support lever is mounted to rotate freely around said shaft in a direction opposite to that in which the torque applying lever applies torque to this shaft, and preventing rotation around said shaft in the direction in which the torque applying lever applies torque to said the shaft, to ensure that it is possible to maintain torque when the lever is supported on the support base [RU 2198087, published: 02/10/2003].

In addition, a device is known, taken as a prototype, disclosed in a patent publication relating to the mounting socket of a hand tool. The mounting socket is formed by a plurality of annularly arranged channels. The number of channels is a multiple of 12. The width of the channel groove is greater than the width of the channel aperture [RU 2280553, published: 07.27.2006].

A disadvantage of the known devices is the inability to use these devices in a limited space and inaccessible places in view of their size.

When repairing, for example, the internal devices of ball valves, there is a need to tighten and loosen the nuts with a torque wrench with a controlled moment. A standard head with a torque wrench having a seat under the head in the form of a square with a spring-loaded ball does not fit between the flanges of the housing, which makes it impossible to use them for these operations.

The objective of the utility model is to create a device for tightening and loosening threaded connections using a torque wrench, which allows for effective tightening of threaded connections using a torque wrench in a limited space and inaccessible places

The technical result achieved by using the device is to reduce the dimensions of the device and fix the torque wrench in it when tightening and loosening threaded connections in hard-to-reach places.

The specified technical result is achieved by the fact that the hand-held device for tightening and loosening threaded connections using a torque wrench comprises a rotatable housing in which a mounting socket is made with a plurality of channels arranged annularly at equal intervals, the number of which is a multiple of 12, and a square hole with the possibility of placing a torque wrench in it, moreover, the square hole is made parallel to the mounting socket, while the perp Two holes of circular cross section are made perpendicular to the hole of square section and intersecting it in the housing at an angle of 90 ° to each other.

A device for tightening and loosening threaded connections using a torque wrench is illustrated by a description of a preferred embodiment and graphic materials, where

in figure 1, the device is depicted in longitudinal section;

figure 2 shows a photo of the device with a torque wrench inserted into it;

figure 3 is a photo of the use of the device during the operation.

Next, with reference to the accompanying graphic material, a device is described for tightening and loosening threaded connections with a torque wrench, made in accordance with a preferred embodiment of the utility model.

The device contains the following structural elements: the housing 1 (Fig. 1) of the device is mainly made flat with the possibility of rotation, in which a hole 2 of square section is made for placement of a torque wrench in this hole. Perpendicular to the hole 2 in the housing of the device 1 there are two holes of circular cross section 3 for fixing in one of them a square with a spring-loaded ball of a torque wrench. At the other end of the housing, the mounting socket of the hand tool 4 is made in the form of a cap head formed by a plurality of channels and configured to accommodate a threaded connection in this head. The hole 2 is located parallel to the cap head 4 and is designed so as to place a torque wrench in this hole in the longitudinal direction to the axis of the device for applying torque.

The device is used as follows. To tighten and loosen the threaded connections, a torque wrench is inserted into the device (Fig. 2), after which the device is mounted on a standardized head with a fastener (Fig. 3). When exposed to the handle of the torque wrench through the inventive device, the force is transmitted to the threaded connection with a certain moment.

Using the proposed device allows you to perform effective tightening and loosening of threaded connections using a torque wrench in hard to reach places.

The manufacture of the proposed device is possible on a lathe, and does not require specialized conditions of metal processing plants.

You must understand that the above example embodiment of the utility model is not limiting the scope of the utility model, and, after reading the present description, specialists in the art can offer many changes and additions to the described embodiment, all of which fall within the scope of legal protection of a utility model, determined by the combination of features of the utility model formula.

Claims (1)
