Description

Overhead ground adjusting foot

Technical Field

The utility model relates to the technical field of interior decoration, in particular to an overhead ground adjusting foot.

Background

In modern building decoration, in order to meet daily use requirements such as heat preservation and noise reduction, a floor is usually raised, and a heating pipe, a sound insulation pad and the like are paved in an overhead layer to achieve the aim. In the development process of the overhead ground, the adjusting feet play a key role, and the main purpose of the adjusting feet is to balance and adjust the height of the ground so as to ensure the stability and levelness of the ground. With the continual advances in technology and the continual change in demand, the design and application of the tuning foot is also evolving and improving.

Among the prior art, the patent of application number 202121727078.5 proposes a but silence shock attenuation's assembled regulation foot structure, and this kind of regulation foot structure installs between floor and ground, including setting up in the fixed part on ground, with fixed part swing joint's movable part, and set up in movable part, be used for accepting the support piece of floor, the distance of movable part to ground is adjustable, be equipped with first flexible pad between movable part and the support piece. When the floor on the adjusting foot support piece is stressed and the support piece moves downwards in the vertical direction under the stress, the first flexible pad can absorb the moving distance of the floor, and the adjusting foot support piece has a good shock absorption effect. But this regulation foot is troublesome to supporting height's regulation, needs to adjust through constantly twisting nut, sleeve threaded connection position on the screw rod, and when the height-adjusting scope was big, the adjustment process was very consuming time, can't swiftly realize making level, heightening.

The patent with the application number of 202210299177.0 proposes an overhead ground adjusting foot and an overhead ground construction process, wherein the overhead ground adjusting foot comprises a rivet nut, a screw rod and a rubber sleeve; the rivet nut is riveted in a prefabricated hole of the plate, the upper part of the screw rod is screwed in the rivet nut, the rubber sleeve is fixed at the bottom of the screw rod, and the rubber sleeve is grounded; the upper end of the rivet nut is provided with an operation port, so that the rivet nut can be used for controlling the screw to rotate by extending a tool into the operation port after the plate is placed at a construction site, and the height of the plate can be adjusted. Through prefabricated trompil to panel to install the nut in the hole in advance, through the operation hole that the nut upper end formed, can directly carry out the fast adjustment to the regulation foot. However, due to the fact that the adjusting feet are used for typesetting and forming a plurality of holes in the plates in advance, and the rivet nuts matched with the screws are arranged in the holes, requirements on typesetting structures of the incoming plates are high, the surface attractiveness of the plates is affected, and adaptability to the market is weak. In addition, because screw rod and panel are directly connected through the nut of preassembling on the panel, because effort between screw rod upper end and the panel is direct through the screw thread transmission, the nut in the hole is become flexible easily after using a period, and makes threaded connection structure wearing and tearing very easily lead to screw rod protrusion panel surface, influences safety in utilization.
