Embodiment Construction

[0026] The technical solutions of the present invention will be further illustrated and described below through specific embodiments.

[0027] like Figure 1 to Figure 4 As shown, a slow-fall rotating shaft mechanism with overload protection includes a housing 1 , a guide sleeve assembly 2 and a rotating shaft 3 .

[0028] The housing 1 is a cylindrical structure with a closed right end, and the inner wall of the housing 1 is provided with an internal thread structure.

[0029] The guide sleeve assembly 2 is provided with an external thread structure compatible with the above-mentioned internal thread structure, so that the guide sleeve assembly 2 can be moved along the axial direction of the housing 1 and fitted in the housing 1, and the guide sleeve assembly 2 From left to right, the space in the housing 1 is divided into a first oil chamber 11 and a second oil chamber 12 filled with damping oil;

[0030] Specifically, the guide sleeve assembly 2 includes a first guide sle...

Abstract

The invention discloses a slow-falling rotating shaft mechanism with overload protection, which comprises a casing, a guide sleeve component, and a rotating shaft, wherein guide sleeves are provided with at least one oil relief hole communicated with a first oil chamber and a second oil chamber; a non-return valve is mounted in the oil relief hole; when the pressure in the first oil chamber is over high, the non-return valve is opened to allow damping oil in the first oil chamber to enter into the second oil chamber through the oil relief hole, so as to accelerate the speed of oil passing from the first oil chamber to the second oil chamber, provide the overload protection, avoid the damage on the slow-falling rotating shaft mechanism due to sudden force close, and improve the strength of the mechanism.

Description

technical field [0001] The invention belongs to the technical field of toilet covers, and in particular relates to a slow-falling rotating shaft mechanism with overload protection. Background technique [0002] The slow-falling shaft mechanism is widely used in various equipment with opening and closing mechanisms, for example, it is used to realize the slow closing of the piano lid, to realize the slow falling of the toilet cover, etc., among which the application on the toilet cover is the most typical , so that the toilet cover can slowly fall when it is closed, reducing noise, and protecting the cover from impact and avoiding other accidents. However, in practical applications, the toilet cover equipped with a slow-falling shaft mechanism will often be forced to close quickly. The upper limit of the bearing will cause damage to the slow-falling shaft mechanism. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the p...
