The nut-turn-screw shift-tight locking device installed in the undermount sink

Abstract

The invention discloses a pressing and locking device adopting nut rotation and screw motion and used for mounting an undermount sink. The pressing and locking device comprises pressing frames, pressing blocks, connecting blocks, compound screw adjusting mechanisms and a rack, wherein each pressing frame is attached to the lower surface of the edge of the sink; each pressing block is in butt joint with the lower end surface of the corresponding pressing frame; the rack is mounted on a cupboard body; each compound screw adjusting mechanism is arranged between each pressing block and the rack, is integrally connected with the corresponding pressing block through the corresponding connecting block and comprises an adjusting nut, a movable screw, a fixed screw and two locking nuts, two ends of the adjusting nut are in left-handed thread connection and right-handed thread connection with the movable screw and the fixed screw respectively, and the movable screw and the fixed screw move in opposite directions through rotation of the adjusting nut and are sleeved with the two locking nuts. The pressing and locking device has the advantages of convenience in mounting and dismounting, simple structure, reliable pressing and locking and the like.

Description

technical field [0001] The invention relates to a compression locking device, in particular to a nut-turned-screw displacement compression locking device installed in an undermount sink. Background technique [0002] At present, there are usually three ways to install the sink: the first is the above-counter basin, which is to place the sink on the countertop of the cabinet from top to bottom. Since the sink has surrounding edges, such placement will inevitably cause the surrounding edges of the sink to be higher than the cabinet. As a result, the overall shape of the sink is not smooth enough, and during use, the water on the cabinet countertop cannot flow into the sink smoothly, resulting in water accumulation on the cabinet countertop. The second type is the Taichung basin, also known as the flush-mounted type, which is to polish a layer on the countertop of the cabinet according to the size of the installation edge of the sink, and make the sink and the countertop a plan...

Problems solved by technology

[0002] At present, there are usually three ways to install the sink: the first is the above-counter basin, which is to place the sink on the countertop of the cabinet from top to bottom. Since the sink has surrounding edges, such placement will inevitably cause the surrounding edges of the sink to be higher than the cabinet. The countertop will cause the overall shape of the sink to be not smooth and beautiful, and the water on the cabinet countertop will not flow into the sink smoothly during use, resulting in water accumulation on the cabinet countertop

The second type is the Taichung basin, also known as the flush-mounted type, which is to polish a layer on the countertop of the cabinet according to the size of the installation edge of the sink, and make the sink and the countertop a plane. Although this installation method is beautiful in appearance, the cabinet countertop is useless The phenomenon of water accumulation is convenient for cleaning, but the strength of the cabinet countertop is greatly weakened. If the sink is filled with water or heavy objects are placed, the polished part of the countertop is easy to break

The third is the under-counter basin, which is to fix the sink to the bottom of the cabinet countertop from bottom to top. This installation method also has the advantages of beautiful appearance, no water accumulation on the cabinet countertop, and convenient cleaning. However, in the prior art, people After the sink is supported from bottom to top, the sink and the countertop are usually only fixed by the leftovers and adhesives of the countertop, so that when people use it, once the sink is filled with water or other heavy objects are placed, The sink is very easy to fall downwards, so that people cannot use the sink safely for a long time

In addition, affected by factors such as the narrow installation space, there is still the disadvantage of inconvenient installation in the prior art where the sink is placed from bottom to top.
