Description

The utility model relates to the mechanical connection of two mutually perpendicular pipes, for example, in a home sports and gaming complex.

A known clamp for connecting two mutually perpendicular pipes made of two identical parts, interconnected and connected by pipes with two threaded, for example, screw connections. The clamp is provided with mutually perpendicular holes for pipes with radii equal to the radii of the connected pipes. Such a clamp is used, for example, to connect handrails in buses, trolleybuses and other types of public transport. The disadvantage of the connection using the known clamp is the presence of two threaded connections and the need for increased accuracy in the manufacture of parts of the clamp to ensure structural rigidity.

The problem solved by this utility model is to reduce the complexity in the manufacture of clamp parts for connecting two mutually perpendicular pipes.

To solve this problem, the clamp for connecting two mutually perpendicular pipes is made of two identical parts, interconnected and one of the pipes connected by a threaded, for example, screw connection. The clamp is provided with mutually perpendicular holes for pipes with radii equal to the radii of the connected pipes. The hole for the pipe connected by a threaded connection is made stepped with a large diameter from the side of the hole for the perpendicularly assembled pipe. Edge transition larger diameter in

a smaller diameter is located between the edge of the clamp and the nearest edge of the threaded hole.

In the described design of the clamp, only one threaded connection is used, and the holes for the pipes to be connected are made with a wide tolerance field, which reduces the complexity of its manufacture and assembly.

The clamp for connecting two mutually perpendicular pipes is shown in the drawings, where:

on figa is a preliminary view of the connection of two mutually perpendicular pipes using a clamp with a larger tolerance of the hole for the pipe without a threaded connection;

The clamp for connecting two mutually perpendicular pipes (Figure 1) is made of two identical parts 1 and 2, interconnected and one of the connected pipes 3 with a threaded, for example, screw connection 4. The clamp is provided with mutually perpendicular holes 5 and 6 with radii, equal to the radii of the connected pipes 3 and 7, respectively. The hole for the pipe 3, connected by a threaded connection 4, is made stepwise with a large diameter of 8 from the side of the hole 6 for the perpendicularly assembled pipe 7. The edge 9 of the transition of the larger diameter 8 of the hole 5 to a smaller diameter equal to the diameter of the connected pipe 3 is located

between the edge 10 of the clamp and the nearest edge 11 of the hole for the threaded connection 4.

The fixation of the mutual arrangement of pipes 3 and 7 under conditions of a significant deviation of the holes for the pipes in the clamp parts or when the tolerance field of the pipes is significant for the outer diameter and their ovality, for example, pipes according to GOST 3262-75, is shown graphically in Fig. 2a and Fig. 3a respectively.

Figure 2a shows the moment when the clamping parts 1 and 2 fixed the pipe 3 in the hole 5 while tightening the threaded connection 4, and a gap B remained between the hole 6 and the outer diameter of the pipe 7. In this case, to fix the pipe 7 in parts 1 and 2 the clamps continue to tighten the threaded connection 4. Parts 1 and 2 of the clamp rotate around the edge 9 until the moment of contact with the pipe 7, as shown in Fig.2b. Thus, the clamping parts 1 and 2 fixed the pipe 3 along the edge 9 and the pipe 7 at the place of contact with the pipe 7.

Figure 3a shows the moment when the clamping parts 1 and 2 fixed the pipe 7 in the hole 6 when tightening the threaded connection 4, and a gap G remained between the hole 5 and the outer diameter of the pipe 3. In this case, to fix the pipe 3 in parts 1 and 2 clamps continue to tighten the threaded connection 4. Parts 1 and 2 of the clamp rotate relative to the pipe 7 until it contacts the pipe 3, as shown in Fig.3b. Thus, parts 1 and 2 of the clamp fixed pipes 3 and 7.

This utility model is industrially applicable, as it can be manufactured using conventional technologies, for example, by casting, at any plant specializing in the production of small steel castings.
