Abstract

The invention relates to mechanical engineering. The purpose of the invention is to facilitate installation and dismantling. This is achieved by the fact that the connection of the plate parts consists of alternating and interlocking protrusions and nests under them. The front part of the protrusions has a shape other than rectangular. The protrusions and sockets form a dovetail-type joint, with the mating side surfaces of the junction being inclined with two different alternating combinations of their directions: the direction of the slopes is multifaceted; the direction of the slopes is one-sided. On the part having protrusions with different directions of inclinations of the side surfaces, there are slots starting at the base of the protrusion, and the front surfaces of the protrusions of the other part are rounded. 7 il.

Description

The invention relates to mechanical engineering, namely to joints of predominantly lamellar parts made of elastic material.

The aim of the invention is to facilitate the assembly-disassembly of the joint.

Figure 1 shows a diagram of the relative position of the dockable parts before their connection, axonometric; figure 2 is the same, side view; on fig.Z - joined parts at the initial moment; in fig. 1 - connection of parts, side view; figure 5 - the same. section aa on fig.Z; figure 6 is the same, the view in the plan; figure 7 is the same, section bb in figure 6.

The connection of the plate-like parts of the resilient material comprises butt-and-fastener parts 1 and 2, consisting of alternating and interlocking protrusions 3 and 4 and nests under them 5 and 6, which form a dove-tail connection. The protrusions 3 of part 1 have side surfaces 7, and the projections 4 of part 2 have lateral surfaces 8. Both surfaces 7 and surfaces 8 are inclined relative to the outer surface of parts 1 and 2. Slope: side surfaces 7 of parts 1 of projections 3 and the side surfaces 8 of the sockets 6 adjacent to them, part 2 have a versatile directionality, and the inclinations of the side surfaces 8 of the projections 4 parts 2 and the side surfaces of the sockets 5 which are associated with them have one-sided orientation (the same side surface 7 relates to At the same time, the protrusion 3 and the nest 5 of the part 1; the same side surface 8 also relates to the protrusion 4 and the nest 6 of the part 2). In such a connection, the mating side surfaces of the protrusions 3 and 4, of the sockets 5 and 6, have tilting directions with two rows

the following different combinations: the direction of the slopes is multifaceted (at the projections 3 and nests 6); the direction of inclination is one-sided (at nests 5 and protrusions 4).

The protrusions 3 of the part 1 have inclined front surfaces 9, and the protrusions 4 of the part 2 have a rounded front surface 10. Such an implementation of the shape of the surfaces of the protrusions 3 and 4 provides a more favorable joining process.

The part 1 has penetrating slots 11, the protrusions 3 starting at the wide base to create more favorable conditions for the process of joining the parts 1 and 2. As in this case the length of the protrusion 3 is increased, while providing easier deflection of the protrusions 3 when joining details 1 and 2.

When joining parts 1 and 2 butt one to another, the protrusions 4 of the parts 2 due to the roundness of their front surfaces 10 push the projections 3 apart in different directions due to the beveled front surfaces 9. The perforations 11 contribute

easier extension of the projections 3. After the mutual position of the parts 1 and 2 reaches the regular one, the projections 3 of the part 1 enter the slots 6 of the part 2.
