An energy-absorbing limit block for a sliding brace

Abstract

The invention provides an energy-absorbing limiting block for a sliding stay, which is connected to the bottom plate of the sliding stay. The energy-absorbing limiting block for the sliding stay includes a collision energy-absorbing limiting block connected to the bottom plate of the sliding The energy-absorbing main part of the collision energy-absorbing limit block close to the end of the slider; wherein, the energy-absorbing main part is used to absorb the energy-absorbing main part from the collision of the slider when the slider is opened to the limit position. The generated collision kinetic energy is transmitted to the collision energy-absorbing limit block. In summary, the present invention increases the energy-absorbing main part, so that the energy-absorbing limit block can absorb kinetic energy in addition to the limit, and at the same time, the energy-absorbing limit block can effectively offset the collision kinetic energy through the energy-absorbing main part, reducing the force arm The probability of rod deformation, and the split design of the energy-absorbing limit block combines the rigid collision energy-absorbing limit block with the flexible energy-absorbing main part. The rigid collision energy-absorbing limit block can improve the strength performance of the sliding support product However, the flexible energy-absorbing main part will not affect 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
