Description

The utility model relates to apparatus for sports exercises, consisting of several parts, for example, gymnastic stairs with fixed vertical racks and horizontal crossbars between them, made of metal pipes.

Known detachable connection of two pipes with perpendicular intersecting axes (patent for utility model RU No. 53924 U1 with a priority of 09/20/2005) containing an insert with a threaded hole fixed in a smaller pipe in cross section and a bolt with washer equipped with a support a part with a blind hole deeper than the length of the protruding part of the insert, commensurate with the cross-section of a smaller pipe in cross section, with a through hole commensurate with the diameter of the mounting bolt, and a bearing surface matching in A profile with a profile of the outer surface of a larger pipe in cross section with which it is in contact. The disadvantage of this design is the presence of a metal insert with a threaded hole, which is pressed into a smaller pipe. Due to the wide range of tolerances of the inner diameter of the pipes, to ensure the conditions of pressing in, mechanical processing of the inner diameter of the pipes of a smaller size to the depth of pressing of the metal insert and mechanical processing of the outer surface of the metal insert for pressing, as well as the assembly of smaller pipes with a tolerance of not more than 0.5 mm With a greater run of the lengths during assembly, the pressed-in metal insert is pulled out of the smaller pipe to align the linear dimensions of the installed pipes. The quality of the press fitting is deteriorating.

The problem solved by the described model is to develop the design of the detachable connection of two pipes with perpendicular intersecting axes with reduced metal consumption and laboriousness.

To solve this problem, the detachable connection of two pipes with perpendicular intersecting axes, one of which is mounted vertically, contains a bolt, a washer, a supporting part with a blind hole, mounted under the washer in contact with the supporting surface of the bolt head, a plug for a blind hole in the supporting part. A horizontally located pipe is mounted on the protruding part of the housing made of plastic or hard rubber and is placed in a blind ring groove of the housing. A through hole is made in the housing along the axis of the housing, commensurate with the diameter of the bolt. A blind hexagonal hole is made in the protruding part of the housing from the installation side of the horizontally located pipe, into which the nut is pressed into the vertical plane against the stop. During assembly, the bolt is wrapped in a nut. The distance between the vertical plane of the blind ring groove of the body and the end of the nut from the side of the vertically fixed pipe is at least 3 mm, which ensures reliable fixation of the body in a horizontally located pipe during assembly by increasing the outer diameter of the protruding part of the body located in a horizontally located pipe, during compression . The supporting surface of the housing along the profile coincides with the profile of the outer surface of the vertically mounted pipe. The proposed design of the detachable connection of two pipes with perpendicular intersecting axes reduces the metal consumption and the complexity by replacing the metal insert on the protruding part of the body and the possibility of expanding the tolerance field of the linear size of horizontally located pipes.

The utility model is illustrated in the figure, where Fig. 1 shows a detachable connection of two pipes with perpendicular intersecting axes, one of which is mounted vertically.

A detachable connection of two pipes with perpendicular intersecting axes, one of which 1 is mounted vertically, contains a bolt 2, a washer 3, a support part 4 with a blind hole 5. A support part 4 is installed under the washer 3, which is in contact with the support surface of the head of the bolt 2. Head of the bolt 2 with the washer 3 are placed in the blind hole 5 and closed after installing the horizontal pipe 6 with a plug 7. The horizontally located pipe 6 is installed on the protruding part 8 of the housing 9 in a blind ring groove. A through hole 10 is made along the axis of the housing 9, commensurate with the diameter of the bolt 2. On the side of the horizontal pipe 6, a nut 12 is inserted into the blind hexagonal hole 11 of the protruding part 8 of the housing 9, into which the screw 2 is screwed in. The distance between the vertical plane A of the blind ring the groove of the housing 9, and the end face of the nut 12 from the side of the vertically fixed pipe is at least 3 mm.

The assembly of the detachable connection of two pipes with perpendicular intersecting axes is carried out in the sequence:

- a washer 3 and a supporting part 4 are mounted on the bolt 2;

- a bolt 2 with installed parts pos. 3 and 4 is inserted into the hole in the pipe 1 through the perpendicular axis, until the supporting part 4 touches the outer surface of the pipe 1;

- the housing 9 is put on the bolt 2 through the hole 10 until the bolt 2 touches the nut 12;

- the bolt 2 is screwed into the nut 12 until the contact surface of the housing 9 touches the outer surface of the pipe 1;

- on the protruding part 8 of the housing 9 is installed horizontally located pipe 6 to the end of the pipe end in the vertical plane A of the blind ring groove of the housing 9;

- the rotation of the bolt 2 on the protruding part 8 of the housing 9 is fixed horizontally located pipe 6;

- the head of the bolt 2 is closed by a plug 7, inserted into the supporting part 4.

This utility model is industrially applicable, as it can be manufactured using conventional technologies used in the production of, for example, children's sports complexes made of metal pipes.
