Description

The utility model relates to the design of devices for physical exercises, namely, to the design of connections of elements of the Swedish walls, gymnastic stairs, horizontal bars, etc. and can be used in the construction of home sports and gaming equipment.

Known for the detachable connection of two pipes with perpendicular intersecting axes (RU, 119245, U1 with a priority of 04/17/2012), one of which is mounted vertically, containing a bolt, washer, support part with a blind hole, mounted under the washer in contact with the support surface bolt heads, plug for blind hole in the support part, housing. A horizontally located pipe is installed on the protruding part of the body until it stops in a blind annular groove. A through hole is made along the axis of the housing, commensurate with the diameter of the bolt, and from the side of the horizontal pipe installation into the blind hexagonal hole of the protruding part of the housing, the nut into which the bolt is screwed is pressed into the stop. 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. A design drawback is the difficulty of the assembly process due to the large tolerance field of the inner diameter of the horizontal pipe. In the case of delivery of a horizontal pipe with a minimum inner diameter during the assembly process, it is necessary to adjust the diameter of the protruding part of the casing to the inner diameter of the horizontal pipe or expand the end of the horizontal pipe to the diameter of the protruding part of the casing. Both of these processes are quite laborious and affect the cost of the product.

The problem solved by the described utility model is to develop the design of a detachable connection of two pipes with perpendicular intersecting axes with a minimum of manufacturing complexity.

To solve the problem, the detachable connection of two pipes with perpendicular intersecting axes contains a bolt, a washer, a support part with a blind hole, mounted under the washer, in contact with the support surface of the bolt head, a plug for the blind hole in the support part, a body resting on the pipe with a through lateral a hole that is provided with a blind end groove and a protruding part with a through axial hole and an end hexagonal hole with a nut pressed into it, into which a bolt is screwed, and the second the th pipe is installed on the protruding part of the housing until it stops against the end of the blind end groove. On the surface of the protruding part of the housing in contact with the inner surface of the second pipe, longitudinal protrusions are made. The distance between the end face of the blind annular groove of the body and the end face of the nut on the pipe side with a through side hole is at least 3 mm. At the end of the protruding part of the housing in contact with the inner surface of the second pipe, a structural entry chamfer is made. The diameter of the base of the protrusions is made equal to the minimum inner diameter of the second pipe, and the height of the protrusions is equal to half the tolerance on the size of the inner diameter of the second pipe. It is allowed to place the protrusions not along the entire length. In this case, the length of the protrusions should be at least 5 mm, and they should be located starting from the end of the blind end groove. The proposed design of the protrusion of the housing facilitates the assembly process by reducing the pressing force, reduces the material consumption of the housing. Thus, a reduction in the complexity and cost of the entire product is achieved. The case can be made of plastic or hard rubber.

The utility model description is illustrated where:

in FIG. 1 - detachable connection of two pipes with perpendicular intersecting axes assembly;

in FIG. 2 - sectional body;

in FIG. 3 - section along a longitudinal protrusion.

The detachable connection of two pipes with perpendicular intersecting axes, one of which 1 with a through side hole, 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 bolts 2 with washer 3 are placed in the blind hole 5 and closed after installing the second horizontally located pipe 6 with a plug 7. The second horizontally located pipe 6 is installed on the protruding part 8 of the housing 9 until it stops against the end face A of the blind ring and the housing 9. 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 portion 8 of the housing 9, into which the screw 2 is screwed in. The distance between the vertical plane A of the blind annular groove of the housing 9 and the end face of the nut 12 from the pipe 1 not less than 3 mm. On the surface of the protruding part 8 of the housing 9 in contact with the inner surface of the second horizontally located pipe 6, longitudinal projections 13 are made. At the end of the protruding part 8 of the housing 9 in contact with the inner surface of the second horizontally located pipe 6, a constructive chamfer 14 is made.

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;

- bolt 2 with installed parts pos. 3 and 4 are inserted into the through hole in the pipe 1 through the perpendicular axis and 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.
