Abstract

The invention discloses a friction self-locking suspension device. The friction self-locking suspension device is used between two opposite and vertical installation surfaces, and comprises a supportrod, two wedge-shaped supports and at least two rolling wheels, the rolling wheels are assembled at the two ends of the support rod, the rolling wheels at the two ends of the support rod correspondingly abut against the inclined surfaces of the two wedge-shaped supports, the weight of the support rod is greater than that of the wedge-shaped supports, the friction self-locking suspension device andthe installation surfaces realize self-locking by friction to be relatively fixed, and the friction self-locking suspension device meets conditions shown in formula (1) or formula (2), wherein N is positive pressure exerted by the rolling wheels on the inclined surfaces of the wedge-shaped supports, G is the weight of the wedge-shaped supports, theta is the inclined angle between the inclined surfaces and the vertical planes of the wedge-shaped supports, Mu is the friction coefficient between the friction self-locking suspension device and the installation surfaces, and G<s> is the weight ofthe support rod. According to the friction self-locking suspension device, by using the friction self-locking principle, the friction self-locking suspension device can be fixed between the two vertical installation surfaces without the need of drilling on the installation surfaces, and at the same time, and great bearing force can be realized.

Description

technical field [0001] The invention relates to a suspension device, in particular to a friction self-locking suspension device. Background technique [0002] In interior decoration, it is often necessary to install hanging devices such as curtain suspenders, towel hooks, and hanging wall cabinets. When installing these hanging devices, it is often necessary to drill holes in the wall surface, thereby destroying the wall surface. Suspensions that do not need to be perforated mainly rely on glue or atmospheric pressure, and the bearing capacity of these suspensions is generally very small. Contents of the invention [0003] The object of the present invention is to provide a friction self-locking suspension device to solve the problem that the existing suspension device will damage the wall surface or have a small bearing capacity during installation. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A friction...
