Description

FIELD OF TECHNOLOGY

The invention relates to clamping devices and can be used, for example, for fixing the elements of drainpipes.

BACKGROUND

The prior art known clamping device (SU No. 1328590, 08/07/1987) D1, containing a split ring with bent ends and a locking element.

The disadvantage of this solution is the need to use a tool (wrench) immediately at the time of placement of the clamping device on the connected part for fastening the split ring and the fixing element.

Known clamping device D2 (RU 2413895 C1, 03/10/2011) containing a locking element and a split ring with bent ends.

The bent ends of the split ring are placed in the reciprocal slots of the locking element and are held in assembled condition by means of a fastening means, which are a bolt or screw with nut. For reliable connection of a bolt or screw with a nut, a tool must be used. Information about other elements that provide the connection of the clamping device in the specified patent is missing.

The disadvantage of this solution is the need to use a tool (wrench) and a fastener (for example, a bolt or screw with a nut) to connect the split ring and the fixing element, which is the reason for the low installation speed of the drainpipe and the inability to install the clamping device by one worker, without involving help .

The source of information D2 selected by the applicant as the closest analogue to the claimed utility model.

DISCLOSURE OF USEFUL MODEL

The objective of this utility model is to eliminate the above disadvantages of the prior art, in particular the need to use additional tools and fasteners to fix the elements of the drainpipes, increase the speed of installation of the drainpipe and make it possible to install the fixing unit with one worker

The technical result of the claimed utility model is to create a structure for connecting the elements of the fixing unit to each other, which does not require the use of fasteners and tools.

The claimed technical result of the claimed utility model is achieved due to the fact that the fixation unit of the drainpipe includes a split ring with bent ends and a fixing element made in the form of a parallelepiped, inside which two partitions are placed, forming grooves between themselves and the walls of the parallelepiped, with each bent end of the split the ring is provided with at least one spike, and the locking element is provided with slots made with the possibility of placing spikes in them.

At the same time, in order to provide additional reliability of the connection of the elements of the fixing unit, the grooves of the fixing element can be made narrowing, allowing to fix the bent ends of the split ring.

IMPLEMENTATION OF A USEFUL MODEL

In figures 1-9 presents the fixing node 1, which contains the locking element 2, made in the form of a parallelepiped and a split ring 3. The locking element 2 is made in the form of a parallelepiped and has a pair of partitions 4, located symmetrically relative to the axis of the fixing node and forming between themselves and the walls parallelepiped grooves 5, one hole 6 at the base, a pair of slots 7 on the outer walls 8 of the fixing element 2. The split ring 3 has bent ends 9. The bent ends 9 of the split ring 3 have one or more spikes 10, odeystvuyuschemu with the corresponding slot 7. The number of recesses 7 corresponds to the number of studs 10. The opening has an extension 6 in the form of hexagon 11 for fixing therein a nut. Additionally, the split ring 3 may contain on its inner surface a uniformly distributed group of protruding elements 12 (Fig. 5), which reduce the contact area of the split ring 3 with the pipe and reduce friction, which facilitates the movement of the pipe in the split ring 3 during thermal expansion.

In order to provide additional reliability of the connection of the elements of the fixing unit, the grooves 5 of the fixing element 2 can be narrowed (Fig. 6), due to which the bent ends 9 of the split ring 3 are sandwiched between the outer walls 8 of the fixing element 2 and the partitions 4, which prevents the studs from popping out 10 of the slots 7 and the disconnection of the elements of the fixation node.

The spikes 10 can be made in the form of a right-angled triangle (Fig. 7), in which the leg, lying on the bent end 9 of the split ring 3, is the width of the spike 10 and the length of this leg depends on the value of the opposite angle, the value of which can be from 45 to 80 degrees. The second leg is a tenon height and has a length of at least 1 mm. Moreover, the height of the spike 10 cannot be greater than the thickness of the outer wall 8 of the fixing element 2 by more than 1 mm.

The width of the slots 7 for the spikes 10, made in the form of a rectangular triangle, may be equal to the width of the spike 10 or more than it, but not more than 1 mm.

Also, the spikes 10 can be in the form of a half cylinder (Fig. 8, 9). The height H of the spike 10, made in the form of a half cylinder, must be at least 1 mm. The width B of the spike 10, made in the form of a half cylinder, must be equal to H * 2.

The width of the slot 7 for the stud 10, made in the form of a half cylinder, should be equal to the width of such a stud 10.

Subject to the above values of the dimensions of the spikes, the most reliable connection of the fixing unit is provided, which does not require the use of fasteners.

The fixing unit for downpipes 1 is installed as follows: the fixing element 2, in a particular design made in the form of a straight parallelepiped with rounded ribs, is fixed to the surface, for example, of a wall by means of a bolt joint located in the hole 6. The split ring 3 is put on the drainpipe. Then the bent ends 9 of the split ring 3 are inserted into the grooves 5 formed by the outer walls 8 of the locking element 2 and the partitions 4 located therein. When the spikes 10 are at the level of the slots 7, the snap connection of the split ring 3 and the locking element 2 occurs instantaneously and you can proceed to the installation of the next assembly. At the moment of locking of the spikes 10 of the split ring 3 in the slots 7 of the fixing element 2, a reliable fixation of the pipe occurs, and therefore no further additional fastening of the fixation unit by means of a fastening element is necessary. Thus, there is no need for an auxiliary worker holding the pipe until the split ring is pulled together with a bolt and nut or other coupling element, and the installation speed of the drainpipe also increases. For example, the worker installing the pipe makes a marking on the wall for the fixing elements 2, fastens them according to the previously applied marking, puts the split ring 3 on the pipe and snaps it into the fixing element 2. At the same time, snap the split ring 3 with the pipe inserted into it the fixing element 2, the worker can with one hand, with the other hand, controlling the correct location of the pipe. At the moment of snap fast, reliable and rigid fixation of the pipe takes place, and the worker can continue to put the following split rings 3 on the pipe and snap them into the corresponding locking elements 2.

When installing the pipe on a horizontal surface, for example, to the ceiling, it is necessary to create two fastening points simultaneously. When using the claimed utility model, the worker of each of his hands can snap one split ring 3 in the locking element 2.

The fixing unit of the drainpipes 1 can be made of a polyvinyl chloride composition.
