Description

Conical coupling sleeves for tubular rods using fixing pins are generally known. In the proposed coupling, these pins, pivotally mounted in one half of the coupling with a conical socket into which half of the coupling is inserted with its friend’s cone, have cutouts and eccentric necks in its middle part, so that with the help of the pins, you can turn the pins, skip the cone of one half coupling to another and fasten them together. For the tightness of the joint, the cone of one half is provided with sleeves of softer metal, ground into the nest walls of the other half of the coupling, and for permanent fixation of the connected parts, the toothed pin heads, to prevent them from turning, are locked with a locking plate.

In FIG. Figure 1 shows a section of the proposed coupling along the axis of the rods it connects; FIG. 2-top view of the coupling; FIG. 3 is a side view of the locking device of the pins.

The coupling consists of two halves 7 and 2, which are screwed onto the tubular rods b, 6 connected by it. Half 7 is a multifaceted (for example, octahedral, as shown in the drawing) prism, the transition at the end to the cone, on the surface of which 316)

lans of softer metal (copper babbitt, etc.) have two or more circular slots 5, 3. f The other half 2 has, within the first half, many-sided and conical sockets; to the walls of the last of them, the 3.3.3 and three, which were located on the walls of the octahedral nest, were passed across the hole in the walls of its octahedral nest 7.7. In the middle part of these pins, adjacent to the lateral parallel edges of the half 7 ,. Cuts 9 of such shape are made so that eccentric semicircular necks 8, 8 form in this place in round pins in the pins, in the outer edges of half 7, in the locations of pins, straight cuts 75 and 75 of semicircular cross sections are made.

The heads of both pins 7 protruding to the outside, in addition to their usual hexagonal shape, are also equipped with toothed ridges 70 on the part of the circumference (Fig. 3). Between both heads can be located, the entrance with its pointed ends into their crests, the locking plate 77, attached to the body of half of the 2 couplings by a screw 72.

To connect the rods, half of the coupling 7 of one rod is inserted into half 2 of the other. At the same time, the pins 7, 7 turn the key, which grips their hexagonal heads, one to the right and the other to the left, so that the eccentric necks 8, 8 fit into the semicircular cuts of the half of the two couplings along the axis with holes for the pins , and would thus not interfere with the passage of the octagonal part of half / into its nest and half 2. By inserting half of the coupling 7, the non-tapered part of its coupling 3 will join the walls of the conical socket in half 2. After that, both pins 7.7 are turned in reverse side otp of their neck 8, 8 will enter into the recesses 13,13 in the half prism / and due to their ekstsentrichoisti will press this full cone clutch us to the socket of the other half, the image in place of touch lapped by Skov 5, 3 and lasting hermetic connection. Finally, a locking plate 11 is inserted between the crests of the heads of both pins and secured with a screw 12. The coupling is disconnected in a similar way, but only in reverse order, and, in the case of a difficult lagging 3, 3 from the walls of the socket, the upper Half of the coupling is turned around its axis by a double-split crowbar, for which this half of the coupling is provided with protrusions 5, 5. The subject invention. 1. A connecting conic sleeve for tubular rods using fixing pins, characterized in that the pins 7, 7 are rotatable and provided in the middle part with notches 9 and eccentric necks 8.8 for the purpose of free passage and clamp half / coupling when inserting conical and its many-sided part in the corresponding socket of the second half of the 2nd coupling enclosing the indicated pins 7, 7, for which half / made the corresponding cutouts 13, 13. 2. Application in the coupling according to claim 1 of the circular 3, 3 of softer metal pritiraemy x to the walls of the socket half of the coupling 2, in order to achieve tightness in the connected parts. 3. Application in the clutch of claim 1 on the pins 7, 7 of the heads, equipped with toothed ridges JO for the locking pins of the locking plate // fixed with screw / 2.
