RU66712U1 - WRENCH WITH TORQUE INDICATOR - Google Patents

Abstract

A wrench that includes a handle with one end of engagement in its design and a sliding sleeve mounted on the handle of the wrench. The voltage measuring device is built into the handle and connected to an electronic display, also built into the key handle. The electronic display screen is displayed on the outer surface of the handle of the key, and it can be completely closed by a sliding sleeve.

Description

FIELD OF TECHNOLOGY

This utility model relates to the field of application of wrenches, the design of which includes a sliding sleeve on the handle of the wrench and a device for measuring force, which allows the magnitude of the torque to be displayed on an electronic display.

BACKGROUND

The conventional wrenches currently in use, capable of displaying the magnitude of the torque, are shown in Figure 1-1 and generally include a handle with an engaging end on one side of the handle and a spring inserted in the handle. The magnitude of the torque that develops with such a wrench is measured depending on the magnitude of the bend of the spring. However, after using the tool for a sufficiently long time, the spring appears to have metal fatigue, and therefore accurate measurements are no longer possible. Another type of traditional wrench currently in use is shown in Figure 1-2. Such a key includes in its design an electronic display located on the outer surface of the key handle. The inherent disadvantage of such keys is that such a display, on the one hand, limits the working space of the key handle, on the other hand, it can easily receive mechanical damage from impacts of external objects.

The present utility model involves the development of such a wrench, the design of which will include a sliding sleeve that will close the electronic display, and thus protect

him.

SHORT INFO. RELATED TO THE USEFUL MODEL

In accordance with one aspect of the proposed model, the wrench will consist of a handle with an engaging end on one side of the handle, and a force measuring device inserted into the handle and connected to an electronic display that will be placed on the outside of the handle handle. Also, a sliding sleeve will be made on the handle.

The claimed model will become more understandable and easily explainable with the help of the attached drawings and drawings, which display, but only for illustrative purposes, the most preferred versions of the present model.

DETAILED DESCRIPTION OF THE MOST PREFERRED EMBODIMENTS

In accordance with Figs. 3 through 6, the wrench proposed in this utility model consists of a handle 10 having two engaging ends on both sides of the handle 10 — an open end 12 'and a square end 12, as well as a force measuring device 20 located on the handle 10. The electronic display unit 30, made on the handle of the key 10, includes the electronic display 31 itself and a number of buttons 32, both the display itself and the buttons are made on the outer surface of the handle 10, and the electronic display 31 is flush with outer surface hinges 10. The electronic display unit 30 is connected to the force measuring device so that when any force is applied to the wrench, the torque value is displayed on the electronic display 31. The sliding sleeve 40 is mounted on the handle 10 and can slide along the handle 10 in such a way as to cover the entire electronic display 31 and adjacent buttons 32. Therefore, the display 31 and buttons 32 are reliably protected from damage during operation.

Figure 1 shows the circuit locks in the display housing 30. Figure 2 schematically shows the principle of measuring torque. S means the length of the arch, 12 is the unit length of the object to which the force is applied, C is the point at which the force is applied. After the force is applied, S> 52, the voltage measuring device 20 is deformed and sends a signal using the so-called "Viston Bridge". Similarly, when the cylindrical object 20 is subjected to torque and rotated at a certain angle, it sends a signal in the form of a changed voltage value. R = pxl / A is the resistance, where A is

This is a unit area. The change in resistance is transmitted to the external circuit, the output voltage is amplified by an amplifier and processed by the processor so that the analog signal is converted into a digital signal, which is then displayed on display 31.

Since we have shown and described the most preferred embodiment of the present model, people with the appropriate qualifications and skills in this field will understand how to make other versions of the present invention without departing from its essence and scope.
