Description

Technical area

The present invention relates to the field of craft tools, in particular a novel tubular socket wrench.

Technical background

The tubular socket wrench is a very useful craft tool. Since he can be plugged with his key head on the nut to be solved and rotated about the same longitudinal axis as that of the nut to be solved, he can also reach nuts in hard to reach places, while a normal fork or ring wrench only in the direction perpendicular to the longitudinal axis the nuts to be solved can be rotated, which is not possible in the presence of hindering parts of the machine in the immediate vicinity of the nuts to be loosened. In the conventional tubular sockets, however, the inner contours of the inner channel of the key head are unchangeable. This has the consequence that the inner contours of the inner channel of the key head with the nuts to be solved not always have sufficient surface contact, but only several point contact points. This can lead to faster wear of the tube piece key and damage to the nuts. There is therefore a need to develop a novel tube piece key, which always ensures sufficient surface contact with the nuts to be loosened.

Content of the invention

The present invention is therefore based on the object to provide a novel tubular socket wrench, which overcomes the shortcomings of the prior art.

This object is achieved by the following technical concept: The tubular socket wrench according to the invention comprises a key head, a pedestal base, six pressure plates and a pressure sleeve surrounding the key head. The pressure plates are each connected with a rod. The sticks stuck through the pressure sleeve and the key head. On the pressure sleeve nuts are provided which secure the rods. The key head has an internal channel into which the rods extend. The pressure plates are attached to the ends of the rods located in the inner channel. Between the spinning sleeve and the outer wall of the key head, a gap is provided in which a positioning frame is placed, which consists of a number of position sheets and a position ring. The position sheets are attached to the position ring. A first closure part and a second closure part are attached to the compression sleeve. At the first closure part, a screw bolt is provided, which corresponds to the second closure part. The pressure plates each have an anti-friction layer on their surface. In the wall body of the key head are receiving holes for the rods 5 intended. The pedestal base is attached to the lower end of the key head. Between the pressure plates and the inner wall of the key head compression springs are attached.

Preferably hinges are attached to the key head, which are each connected to a mounting rod. The mounting rods are each connected to a mounting rod. Notches are provided on the pressure sleeve, into which the fastening rods engage. The mounting rods are cylindrical. At the periphery of the key head, an upper mounting sleeve and a lower mounting sleeve are attached. The pusher sleeve is attached to the key head by means of the mounting sleeves. The mounting rods are designed as telescopic rods.

Preferably, a first elastic layer is provided between the position sheets and the inner wall of the spinning sleeve, wherein between the position sheets and the outer wall of the key head, a second elastic layer is provided.

Preferably, a recess is provided on the first closure part, wherein on the second closure part a bead is provided, which engages in the recess. The first closure member, the second closure member and the bead have a common bolt hole into which the bolt can be screwed.

Preferably, the number of position sheets is six, wherein the position sheets are configured circular.

Preferably, the key head and the pedestal are welded together.

When adjusting the pressure plates, the position frame is used. To extend the pressure plates deeper into the inner channel, thinner position sheets are selected. Conversely, thicker position sheets are chosen so that the pressure plates extend less into the inner channel. The elastic layers ensure that the outer wall and the position sheets do not wear out and damage each other when pressed against each other.

The closing of the pressure sleeve is effected by the closure parts. Both fasteners are pressed together, with the bead snap into the recess. Then the bolt is screwed into the bolt hole. Thus, the pressing sleeve is tightly clamped around the key head and the rods together with the pressure plates are pressed into the inner channel to firmly clamp the nut to be loosened.

embodiment

In the following an embodiment of the present invention will be explained in more detail with reference to the drawings.

As in 1 to 6 shown, the pipe socket wrench according to the invention comprises a key head 1 , a pedestal base 2 , six pressure plates 3 and one the key head 1 surrounding compression sleeve 4 , The pressure plates 3 are each with a chopstick 5 connected. The chopsticks 5 stuck through the pressure sleeve 4 and the key head 1 , At the pressure sleeve 4 are nuts 6 provided the chopsticks 5 Fasten. The key head 1 has an internal channel 7 on, in which the chopsticks 5 extend. The pressure plates 3 are at the ends of the chopsticks 5 attached, located in the inner channel 7 are located. Between the pressure sleeve 4 and the outer wall of the key head 1 is a gap 8th provided in which a position frame 9 placed from the position sheets 10 and a position ring 11 consists. The position sheets 10 are at the position ring 11 appropriate. At the pressure sleeve 4 are a first closure part 12 and a second closure part 13 appropriate. At the first closure part 12 is a bolt 14 provided with the second closure part 13 corresponds. The pressure plates 3 each have an anti-friction layer on their surface.
