Description

The utility model relates to accessories for fixing mixers to a sink plate.

Means for fixing mixers to a sink are known from the prior art, which use a pressure screw and a fixing bracket.

It is inconvenient to fix these faucets, since you need to crawl under the sink in case of replacing the faucet in order to remove it and then fix the new one.

A more convenient type of faucet is a kitchen faucet with a pull-out spray, for example, [http://varion.ru/catalog/smesiteli/dlya-kukhni/1-r-knp-izl-lux/smesitel-s-vydvizhnym-izlivom-elit -lux], which use a mechanism for quick mounting and dismantling of the mixer, according to patent US9212474 (publ .: 2015-12-15). This mechanism for quick assembly and disassembly of the mixer was chosen as a prototype. It includes the main body, movable threaded guides located inside the connecting ring, a press plate, which is movably located inside the connecting ring, pressure blocks abutting with a wedge against movable threaded guides, which are driven by a pressure plate rigidly connected to the pressure blocks. When the main body is pushed towards the top of the sink to press the mixer against it, the sink plate will press down on the pressure blocks, and those will press on the threaded rails that threaded to hold the pressure sleeve on the mixer. The device conveniently and quickly fixes the mixer to the sink and also quickly disconnects from it.

The technical problem of the prototype is the presence of a complex locking mechanism of many parts, in which a spring in the form of an arcuate bracket is used to squeeze out threaded blocks, and a whole segment of nodes forming a locking block is used to compress them, placed inside a receiving socket. This locking block consists of: a connecting ring with grooves, holes and recesses, inside which movable guides with a thread are placed, pressure blocks, an elastic spring-bracket are inserted, and from above there is a pressure plate, which has locking hooks. In addition, the entire locking mechanism of the connecting ring is fixed inside the socket using another additional lock - a fastener with guides.

The task of the utility model is to eliminate the indicated technical problems while maintaining the function of quick assembly and disassembly of the mixer.

The technical result is to simplify the design of the device for quick installation and dismantling of the mixer, the ability to produce, store and transport the device disassembled, the ability to replace individual elements in case of breakdown.

The specified technical result is achieved due to the fact that the claimed device for quick mounting and dismantling of the mixer, consisting of a bushing having at the end a shortened bushing of a larger diameter and an annular lock block located inside the seat of the bushing of a larger diameter, and equipped with movable locking guides with a thread in the form ring segments, a pressure annular plate, pressure blocks abutting with a wedge against movable threaded guides, which are made with the possibility of displacement from the pressure plate associated with the pressure blocks, characterized in that the bushing seat of a larger diameter has grooves inside that form cavities for inserting the pressure blocks , each of which has a thrust base in the form of a plate, which is configured to shrink into a groove, and a wedge located in the upper part; each movable threaded guide contains a wedge-shaped protrusion located in its upper part and interacting with the wedge of the pressure block.

It is permissible that a spring is fixed to the thrust base of the pressure block, which is adapted to be inserted onto the rod, which is located at the base of the socket of the sleeve of a larger diameter.

It is possible that a wedge is located in the upper pressure block, on the surface of which a pin with a tip is fixed, and the pressure ring plate has through holes in the form of annular segments, into the cavity of which a pin is inserted, protruding above the pressure ring plate at least with a tip.

Implementation of the utility model

The claimed device for quick assembly and disassembly of the mixer consists of a sleeve 1 (see Fig. 1) having at the end a shortened sleeve 2 of a larger diameter and an annular locking block located inside the seat of the sleeve 2 of a larger diameter, and equipped with movable guides 7, locking with a thread 8 in the form of annular segments, a pressure ring plate 13, pressure blocks 10 abutting with a wedge against movable guides 7 with threads 8, which are made with the possibility of displacement from the pressure plate 13 associated with the pressure blocks 10.

What is new is that the seat of the sleeve 2 of a larger diameter has grooves 5 inside, formed by the spaces between the segments 4 of the inner radius of the sleeve 2 of a larger diameter. The grooves 5 form cavities for inserting the pressure blocks 10, each of which has a thrust base in the form of a plate, which is configured to shrink into the groove 5, and a wedge located in the upper part.

Each movable guide 7 with thread 8 contains a wedge-shaped protrusion 9 located in its upper part and interacting with the wedge of the pressure block 10.

As a possible variant of execution, but not obligatory, a wedge can be located in the upper part of the pressure block 10, on the surface of which a pin 11 with a tip is fixed. In this case, the pressure ring plate 13 can have through holes 15 in the form of annular segments, into the cavity of which a pin 11 is inserted, protruding above the pressure ring plate 13 at least with its tip.

The holes in the form of ring segments 15 can be formed, for example, by the outer ring of the plate 13 and the central ring 16, between which the connecting elements 14 are located (see Fig. 3).

To increase the convenience of fixing the elements inside the seat of the sleeve 2 of a larger diameter, a spring 12 can be fixed to the thrust base of the pressure block 10, which can be inserted onto the rod 6 located at the base of the seat of the sleeve 2 of a larger diameter (see Fig. 2).

The principle of operation of the device is as follows.

First, all the elements of the device are put together as shown in Fig. 4. For this (see Fig. 4 (c)), segments of the movable guides 7 are placed in the socket of the sleeve 2 of a larger diameter. Then, the pressure blocks 10 are placed in the grooves 5 (see Fig. 4 (b)). A pressure ring plate 13 is placed on top so that the ends of the pins 11 of the pressure blocks 10 enter into its through holes 15 (see Fig. 4 (a)). Preferably, before fixing, the pressure plate 13 should be turned counterclockwise until the pins 11 stop against the edges of the holes 15 of the ring segments so that the maximum angle for turning the plate 13 is.

If the pins 11 and through holes 15 are not used in the manufacture of the device, then the pressure plate 13 is simply superimposed on top, with the orientation of alignment of the contours of the circles of the plate 13 and the sleeve 2 of a larger diameter.

In the form (see Fig. 4 (a)), the device is ready for fixing the mixer, which is carried out in the manner shown in Fig. 6.

The inlets 21, fixed in advance to the mixer 20 on its clamping sleeve 19, are passed first through the silicone or rubber gasket 18, and then through the hole 3 in the sleeves 1 and 2. A ring is used as a gasket 18, which is close in shape to the outer ring of the pressure plate 13 so that its inner diameter does not touch the pins 11.

To fix the mixer 20, it is enough to press the sleeve 1, holding it by hand, on the inner surface of the sink plate 22 and turn it slightly clockwise (to tighten). As a result of such actions, the pressure plate 13 on the one hand rests tightly against the gasket 18, and on the other hand freely scrolls at a certain angle relative to the pins 11. In this case, the pressure plate 13 (see Fig. 5 (a)) on the pressure blocks 10 leads to the pressure of their wedges on the wedge 9 of the movable guides, which are displaced to the center (see Fig. 5 (b)), wrapping their threads 8 around the external thread of the pressure sleeve 19 of the mixer 20. When the thread 8 shrinks onto the thread of the pressure sleeve 19, and simultaneous pressure on the inner surface of the sink plate 22, a jamming effect occurs, due to which the claimed device conveniently and quickly fixes the mixer to the sink (see the position in Fig. 7).

For the same quick and convenient disconnection of the mixer 20 from the sink plate 22, it is enough to slightly turn the sleeve 1 by hand to unscrew it counterclockwise and wander a little to the right-left and back and forth. As a result, the pressure on the wedges 9 will weaken, and the movable guides 7 under the action of the bolt will move away from the thread of the clamping sleeve 19. Then the device can be easily removed from the clamping sleeve 19 together with the branches 21.

In comparison with the prototype in the claimed device, there are only a few elements that simply fit into the socket of the sleeve 2 of a larger diameter without the need for fixation in it. If necessary, certain elements can be replaced in the declared device if they become unusable (break). The device can be supplied unassembled.

Thus, the claimed device is simpler in design, it can be produced, stored and transported in a disassembled state.
