A limit mechanism of high frequency waist support pad

Abstract

The invention discloses a limiting mechanism of a high-frequency waist protecting pad. The limiting mechanism comprises a waist protecting cotton cushion; the left sides of the obverse and reverse sides of the waist protecting cotton cushion are fixedly connected with limiting bars; the ends, far away from the waist protecting cotton cushion, of the limiting bars are provided with fixing devices;and the surfaces of the limiting bars are sleeved with limiting sleeves I and limiting sleeves II located at the right sides of the limiting sleeves I. According to the limiting mechanism, the positions of the limiting sleeves I and the limiting sleeves II are fixed by fixing mechanisms by virtue of fixing sleeves, then, the limiting sleeves I are fixedly arranged on the surfaces of the limiting bars by a hold-down mechanism, and finally, the waist protecting cotton cushion is limited by the limiting sleeves I and the limiting sleeves II by virtue of limiting plates, so that the limiting mechanism has the advantage that the waist protecting cotton cushion is convenient to limit when being used; the problem that an existing waist protecting cushion is not provided with the limiting mechanism and is only fixedly arranged on the surface of a chair backrest by using fixing bars to result in displacement easily caused by body rotation is solved, the stability during use of the waist protecting cushion is used is improved, and the waist protecting cushion is convenient for people to use.

Description

technical field [0001] The invention relates to the technical field of waist support pads, in particular to a position-limiting mechanism for high-frequency waist support pads. Background technique [0002] When people sit for a long time, the back and lower back of the human body will be easily fatigued, and the muscles of the lower back will also cause pain. At present, there are many waist protection products on the market, such as sponge lumbar pillows, lumbar pads, or car lumbar and backrests. Etc., to improve people's comfort when sitting for a long time. [0003] The high-frequency waist support pad is one of the waist support pads, but the existing waist support pads do not have a certain limit mechanism, and are only fixed on the surface of the chair backrest by fixing strips, causing the waist support pad to easily appear due to body rotation. The phenomenon of displacement reduces the stability of the waist support pad in use and is not convenient for people to u...
