Description

The invention relates to pipe connections, namely to a detachable clamp for connecting three mutually perpendicular pipes, which can be used to connect horizontal bars, gymnastic stairs with vertical stands in game and sports complexes.

A known clamp for connecting two mutually perpendicular pipes (RU, Patent No. 66209, published September 10, 2007) is made of two identical parts, interconnected and one of the pipes to be connected by a threaded, for example, screw connection, equipped with an opening for pipes with radii, equal to the connected pipes.

This design allows you to connect two mutually perpendicular pipes, but its disadvantage is the unreliability of the connection due to the use of only one bolt and the limited crimping force formed by the thin rear wall of the clamp.

The closest device of the same purpose, which is adopted as a prototype, is a detachable clamp for connecting two mutually perpendicular pipes, consisting of two half rings made with the possibility of covering the outer surface of the pipe of a given diameter, where the first half ring has one through hole at each end with the possibility passing through each hole of the clamping screw, and the second half-ring has on each of the ends one recess (hole) with the possibility of threaded retention in each recess ii one screw. The half rings form two mutually perpendicular communicating planes of cylindrical shape, where the first cavity is formed by the inner surface of the half rings, and the second cavity is formed by two symmetrically located grooves made on the end surface of one of the mating ends of each half ring, with the possibility of through passage through the specified cavity of one of the clamping screws (RU, Patent No. 126420, published March 27, 2013). The design of this detachable clamp allows for a reliable and durable connection of two mutually perpendicular pipes.

The disadvantages of this utility model include the complexity of the design, namely the separate execution of two half rings. This design of the detachable clamp allows only two perpendicular pipes to be connected.

The technical problem, which is aimed by the claimed utility model, is to ensure the structural versatility of the detachable clamp, which is made of two identical half rings, as well as increasing the number of connected perpendicular pipes.

The specified technical problem is solved in common with the prototype: the presence of a half ring, one of the ends of which has one through hole, with the possibility of a clamping screw passing through it; recesses (holes) made on the end surface of the half-ring, with the possibility of threaded holding in it one clamping screw; made at the end of the semicircle of the through groove of a semicircular shape.

To achieve this result, the detachable clamp is made of two half-rings of the same design. The half-ring has one recess on one of the external surfaces with the possibility of immersing the clamping screw head into it, coaxial with the through hole, which is configured to allow the clamping screw to pass through it. At the opposite end of the semicircle, a recess (hole) is made with the possibility of a threaded retention of one screw in it. On both end surfaces of the semicircle, through semicircular grooves are made, which, when the detachable clamp is assembled, form two cylindrical cavities perpendicular to the inner cavity of the semicircles.

The expanding clamp, consisting of half rings of the claimed design, allows you to connect two coaxial pipes with one perpendicular due to the formation of three communicating cavities of a cylindrical shape. The first cavity is formed by the inner surface of the semicircles, and the second and third cylindrical cavities are formed by two symmetrically located semicircular grooves made on the end surfaces of both mating ends of each semicircle, allowing two clamping screws to pass through these cavities.

Figure 1 is a General view of a detachable clamp (longitudinal section);

Figure 2 is a three-dimensional model of a detachable clamp.

The detachable clamp (Fig.1-2) consists of two identical half rings 1, interconnected by two clamping screws 2, passing through the through hole 3 on the end surface of the half rings, and held by a threaded connection in the recesses (holes) 4 with thread. Thus, there is a contraction of two half rings, compressing the pipe with its inner surface 5, providing a rigid fixed connection. At both ends of each semicircle, a groove 6 of a semicircular shape is made. When connecting two half rings, their conjugate end ends with grooves 6 form a second 7 and third 8 cavity of cylindrical shape, which communicate with the first cavity, and their axis is perpendicular to the axis of the first cylindrical cavity 5 formed by the inner surface of the half rings.

The second and third cavities are made with the possibility of passage of clamping screws through them, while clamping screws simultaneously pass through the end part of a perpendicularly fixed pipe, thereby preventing its longitudinal or axial displacement.

The inner surface of the half rings compresses the support pipe from opposite sides. The thickness and dimensions of the clamp are selected in accordance with the diameter of the pipes to be connected and their intended purpose. It is preferable that when covering the pipe between the end surfaces of the half rings there is a small gap, which makes it possible to tighten the clamp half rings around the pipe with two screws.
