The task is to develop a universal cylindrical collapsible coupling, used both along a newly laid cable-carrying route and along a previously installed pipe system.

The technical result is to increase the ease of installation.

The technical result is achieved due to the fact that the collapsible cylindrical coupling consists of two identical parts connected by means of locks in the form of a latch; on the side on the split line, when connecting the parts, a groove is formed, which makes it possible to open the parts with the help of a hand tool, on the inner side in the center of each part there is a recess for the fastener.

Description

The utility model relates to socket connections and can be used to connect corrugated and smooth pipes of various sizes without the use of special tools, both along a newly laid cable-carrying route and along a previously installed pipe system, including the transition from a corrugated pipe to a smooth one standard size .

Known coupling for corrugated pipes [Patent RU No. 141815, IPC H02G 3/06, publ. 06/20/2014]. The coupling is made of plastic, symmetrical about the center. The coupling has four hooks that follow the contour of the pipe. The ends of the coupling have a straight section parallel to the pipe, which is larger than the pitch of the pipe corrugation, which makes it possible to exclude the possibility of the ends of the coupling falling into the recesses of the pipe corrugations and, as a result, to reduce the likelihood of damage to the couplings and pipes during transportation and installation of pipes.

The disadvantage is the inability to disassemble the coupling, which makes it inapplicable to pipes in which the cable is already laid. There is no space for screw mounting, which significantly reduces versatility.

Known coupling for detachable connection with a pipe [Patent US 3268244 A, 23.08.1966, IPC F16L 21/00; F16L 25/00], containing: a frame consisting of a base having a substantially rigid annular end surface, and a plurality of protruding rod-like elements fixed, in general, equiangularly around said surface, said elements being made of a material and having a length ratio to thickness to provide said elements with an elastic characteristic such that, within their elastic limit, they will twist and deform radially inward relative to said annular end surface when a torque is applied to said elements:, flexible means fixedly attached to said elements to form, along at least one section of a continuous periphery of the pipeline, which extends from the specified annular end to the end of the specified elements remote from the specified surface; and means on the outer side of said flexible means for releasably connecting said joint to said pipe while reducing the diameter of said joint, said pliable means by applying a twisting force between said base and ends of said elements remote from said base.

The disadvantage is the inability to disassemble the coupling, which makes it inapplicable to pipes in which the cable is already laid.

The task is to develop a universal cylindrical collapsible coupling, used both along a newly laid cable-carrying route and along a previously installed pipe system.

The technical result is to increase the ease of installation.

The technical result is achieved due to the fact that the collapsible cylindrical coupling consists of two identical parts connected by means of locks in the form of a latch; side on the parting line, when connecting the parts, a groove is formed that makes it possible to open the parts with a hand tool; on the inside, in the center of each part, a recess is made for the fastener.

On FIG. 1 shows a separate part of the clutch.

On FIG. 2 shows the coupling assembled from two parts.

On FIG. 3 shows the clutch disassembled from the inside.

On FIG. 4 shows the coupling end view.

On FIG. 5 shows the locks and the groove of the coupling.

On FIG. 6 shows a coupling with a cut out part.

The collapsible cylindrical coupling consists of two identical parts 1 connected by means of locks 2 in the form of a latch, on the inner side of the parts 1 at an equal distance from the edges to the center there are protrusions 3 in the form of ribs for fixing corrugated or smooth pipes. A groove 4 is formed on the outer side of the coupling on the split line when connecting parts 1, which makes it possible to open the parts using a hand tool. On the inner side in the center of each part 1 there is a recess 5 for the fastener.

Groove 4 is formed on the coupling parting line and is intended for a more convenient separation of parts 1 of the coupling.

Consider an example of using a clutch.

The collapsible coupling is used when laying cable lines in corrugated or smooth pipes, when one pipe section ends and it is necessary to dock without interruption with the next pipe section; in the event of breakage of the corrugated pipe along a pre-assembled route in order to hide a break or crack in the corrugated pipe; when connecting two segments of smooth pipes or switching from a smooth pipe to a corrugated one.

It is for continuous connection that couplings are used, while collapsible couplings are considered a more convenient way of connecting due to the fact that they rigidly fix the pipe (s) inside due to protrusion 3 (limiter).

For all the above cases, one part 1 of the coupling is fixed to the wall through the recess 5 using a screw 6 with a countersunk nut. The pipes are located along the inner side of the coupling up to the protrusions 3 and with the help of locks 2 by means of a latch (passage of the protrusion on one part 1 of the coupling into the cavity of the other part 1) connect the two parts 1 into one coupling. A groove 4 is formed on the outer part 1 of the coupling, which, if necessary, is used to insert a screwdriver into it and, using a small force, separate the two parts 1 in order to correct something or completely replace one loose part 1.

On each part 1 of the coupling at the place of closure there are protrusions and depressions, which, by getting the protrusion into the cavity, form a connecting lock 2. When two parts 1 are combined, the lock 2 is formed from the contacting elements of both halves. On one part of the lock 2 there is a protruding tongue with a ledge, and on the opposite part there is a depression. Closing of the lock 2 occurs with a stretch due to the bending of the tongue with the protrusion, which returns to its original position after the protrusion hits the cavity, and a click is heard. As a result, a tongue with a protrusion, which has fallen into a cavity, keeps the coupling from spontaneous opening.

For separation, it is necessary to apply force at the junction of the two halves, forming a groove 4, which contributes to a more convenient opening. Disconnection can be done with tools or manually.
