Energy absorption limiting block for sliding support

Abstract

The invention provides an energy absorption limiting block for a sliding support. The energy absorption limiting block is connected to a sliding support bottom plate. The energy absorption limiting block for the sliding support comprises a collision energy absorption limiting block body connected to the sliding support bottom plate and an energy absorption main part connected to the end, close toa sliding block, of the collision energy absorption limiting block body. The energy absorption main part is used for absorbing collision kinetic energy generated when the sliding block collides with the energy absorption main part when the sliding support is opened to a limiting position and transmitting the kinetic energy to the collision energy absorption limiting block body. In conclusion, by additionally arranging the energy absorption main part, the energy absorption limiting block can achieve limiting and can also absorb kinetic energy; meanwhile, the energy absorption limiting block caneffectively offset collision kinetic energy through the energy absorption main part, and the deformation probability of a moment arm rod is reduced; and furthermore, through the split design of the energy absorption limiting block, the rigid collision energy absorption limiting block body and the flexible energy absorption main part are combined, the right collision energy absorption limiting block body can improve the strength performance of the sliding support product, and the flexible energy absorption main part does not influence the strength performance of the limiting block.

Description

technical field [0001] The invention relates to the field of door and window accessories, in particular to an energy-absorbing limit block for a sliding stay. Background technique [0002] The existing sliding stay products basically use a four-link movement mechanism, and under this mechanism, when subjected to a large opening and closing force, it is easy to cause deformation of the rod. Once there is a slight deformation, a long-term After repeated opening and closing cycles, the deformation will be magnified, which will eventually lead to serious deformation of components, failure of sliding stay products, and greatly reduced performance of doors and windows. [0003] After a large number of searches, it was found that the limit block used for the sliding stay in the prior art, such as a kind of positioning sliding stay for casement windows disclosed by the publication number CN101250964A, through the cooperation of its static slider and moving slider, after the flat sas...

Problems solved by technology

[0004] To sum up, the limiting blocks for sliding stays in the prior art only have the function of limiting, and when people open doors and windows, they always use a lot of force to open them to the end at one time, and the sliders of the sliding stays hit the limiting blocks It is easy to shift or deform the limit block when it is on, or even fall off, which will lead to the failure of the sliding stay and the deformation of the bottom plate of the sliding stay
