Abstract

The node connecting the elements of the designer or mechanical model contains the first group of parts and the second group of parts. The first group of parts contains three separate parts, two ends of which have protrusions and longitudinal grooves, between the end parts is a middle connecting part with holes through which the grooves of the end parts are inserted to create an axis, and the bottom and top of the node are fixed the second group of details. Moreover, the protrusions at the ends of the axis are made with the possibility of bending perpendicular to the direction of the axis of the node to fix it.

Description

The useful model belongs to the nodes of connection of elements of construction sets, in particular for the connection of fixed and moving parts in sets of three-dimensional mechanical models, and can be used in the manufacture of children's, game and souvenir construction sets.

A well-known node of individual moving elements of a mechanical model capable of moving around one axis (Patent Sha 95685 O, IPC AEZN 33/00, AEZE 9/12, publ. 12/25/2014, contains an axis and details of individual moving elements that are connected between The assembly includes a first and a second group of component parts, wherein the first group of component parts includes at least two individual parts, and each of the individual parts of the first group includes a central hole for insertion into the center hole of the axle, each of at least than two separate parts of the first group contains at least two rectangular connecting holes (OA Mo 95685, AbZN 33/00, AbZE 9/12, publ. 12.25.2014).

The disadvantages of this technical solution are: insufficient reliability of the connection due to the presence of uncompensated gaps in the holes of through holes; execution of parts of the node from sheet plywood, and axes - from wood with lower hardness, which leads to rapid wear of the created node; temperature and humidity in the room have a significant effect on the reliability of connections and the shelf life of parts.

The closest thing to the claimed useful model is the connection node of the elements of the designer or mechanical model containing the first group of parts and the second group of parts. The first group of parts contains at least one separate part, which is made with at least two symmetrically located protrusions, and each of the separate parts of the second group contains a central hole and at least two connecting holes, which are located around the central hole. The parts of the first group are made with a longitudinal groove to ensure the possibility of their installation in a cross shape with the longitudinal groove of one part entering the longitudinal groove of the other to connect the transverse grooves of both parts of the first group and create the shaft of the unit. The protrusions on individual parts of the first group are designed to enter the holes made on the parts of the second group, and are made with the possibility of bending in the direction of the axis of the node |OA Mo 119137), AbZN 33/00, publ. 11.09.2017 Bul. Mo 17).

The disadvantage of this technical solution is: the complexity of the shape of the parts of the node and ensuring the necessary mutual placement due to the presence of additional holes around

From the central hole of the parts of the second group, which causes difficulties in the manufacture and assembly of the unit by the user in case of a small error or displacement of the protrusions and/or holes; insufficient reliability of the connection, rapid loss of elastic and/or mechanical properties by the axis, the occurrence of backlashes, malfunctions of the axis of the parts, due to insufficient fixation of the parts of the second group by stops and/or protrusions, which are made with the possibility of bending in the direction of the axis at an angle of no more than 40.

The basis of the useful model is the task of improving the connection node of the elements of the designer or mechanical model, in which, due to the use of a new implementation of the shape of the parts, their mutual location and fastening, reliable fixation of the node parts during their interaction with each other is ensured, and the possibility of backlash in all directions relative to axes during operation, ease of manufacture and assembly of unit parts.

The task is solved by the fact that the connection node of the elements of the designer or mechanical model contains the first group of parts and the second group of parts. The first group of parts contains three separate parts, the two extremes of which have protrusions and longitudinal grooves, between the extreme parts there is a middle connecting part with holes through which the grooves of the extreme parts are inserted to create an axis, and the node is fixed from below and above with latches with a cross-shaped hole of the second group of details. Moreover, the protrusions at the ends of the axis are made with the possibility of bending perpendicular to the direction of the axis of the node for its fixation.

The details of the first and second groups are made of sheet metal with a thickness of at least 0.1 mm.

The use of elements that have special protrusions, made with the possibility of bending perpendicular to the direction of the axis of the node, allows you to easily and at the same time reliably fasten the parts together in all directions, ensuring reliable fixation of the parts of the first and second groups to each other, thereby ensuring the strength and efficiency of the structures, the absence of backlashes and the impossibility of their occurrence during operation.

A junction of elements of a designer or mechanical model, containing the first group of parts and the second group of parts. The first group of parts contains three separate parts 1, 2, 3. The two extreme parts 1, C have protrusions 4 and longitudinal grooves 5. Between the extreme parts 1, C there is a middle connecting part 2 with holes 6, through which the grooves 4 of the extreme parts are inserted parts 1, C to create an axis (Fig. 1). From below and above, the node is fixed with fasteners 7, 8 with a cross-shaped hole of the second group of parts, and the protrusions 9 on the axis are made with the possibility of bending perpendicular to the direction of the axis of the node for its fixation (Fig. 2-5).

The details of the first and second groups are made of sheet metal with a thickness of at least 0.1 mm.

The junction of the elements of the designer or mechanical model is made as follows.

The protrusions 4 of the parts 1, C are inserted into the holes 6 of the connecting part 2, forming an axis (Fig. 2). After that, the fixator 7 (Fig. 3, Fig. 4) is attached from below, and the fixator 8 (Fig. 5, Fig. b) is attached from above, then the protrusions 9 on the axis are bent for fixation, obtaining a ready assembly (Fig. 7).
