Description

Automatically correct the hinge structure

The invention relates to the technical field of architectural hardware, in particular to a hinge structure with an active correction function.

A hinge is a device used to connect or rotate, so that the door, cover or other swinging parts can be turned on and off by the rotation of the hinge, and the hinge is usually connected by a pin. It consists of a pair of metal sheet bushes.

At present, the traditionally used hinges on the market are all installed on the door leaf and door frame by screws. Generally, at least one hinge is installed on the upper and lower ends of the door leaf. However, for larger door leaf size and quality, there will be more than two on the door leaf. The different shafts of the hinges cause the door leaf to tilt. After long-term use, it takes a lot of effort to push and pull. At the same time, the friction between the central shaft and the central sleeve increases, which makes the loss faster, which will shorten the hinge. Life.

Therefore, if we can develop an automatically correcting hinge structure, it is the problem that the creator wants to improve.

Therefore, the inventor of the present invention is in view of this, thinking and creating ideas, so he designed with many years of experience, and after many discussions and trial samples, and several modifications and improvements, he came up with the present invention.

The automatic correction hinge structure of the present invention includes: an upper shell and a lower shell, the lower end of the upper shell is fixed with a central axis extending from the upper shell, and the inner wall of the lower shell is provided with There is a central shaft sleeve, the central shaft is sleeved into the central shaft sleeve, so that through the relationship of the phase set, the upper shell and the lower shell can follow the central shaft and the central shaft under force The sleeves pivot to each other, and the side walls of the upper shell and the lower shell are fixed with a hinge piece protruding to the side, wherein a tapered roller bearing is installed on the central shaft, and the lower shell A tapered bearing sleeve is sleeved above the center sleeve of the body. The tapered bearing sleeve is matched with the tapered roller bearing, so that the inclination of the inner wall of the tapered bearing sleeve can match the inclination of the tapered roller bearing surface With the same degree, the inner wall of the lower shell is directly sleeved with the tapered bearing sleeve that matches with the tapered roller bearing to ensure that the upper shell and the lower shell use the center The accuracy of the coaxial connection between the shaft and the central shaft sleeve as a set, which can effectively reduce the friction loss between the central shaft and the central shaft sleeve, so that the central shaft can have a higher load carrying capacity and extend its use Life; thereby, the system can form the automatic correction hinge structure.

In the automatic correction hinge structure of the present invention, the tapered roller bearing on the central shaft is matched with the tapered bearing sleeve on the inner wall of the lower housing, in addition to helping the central shaft to be actively guided, It can also ensure that the central shaft is not loose during use, and the structure of the hinge is simple, and the processing of the tapered roller bearing is also quite convenient and not complicated. The installation of the tapered roller bearing and the tapered bearing sleeve is improved. The load strength can also enable the hinge to have a higher bearing capacity.

In order to enable your reviewer to have a further understanding and understanding of the purpose, features and effects of the present invention, please cooperate with the following [simple description of the drawings] as detailed below: usually according to the present invention, please start from the first figure to the first figure As shown in the four figures, the present invention provides an automatic correction hinge structure, which includes: an upper shell (10) and a lower shell (20), the lower end of the upper shell (10) inherently extends The central shaft (11) of the upper housing (10), the inner wall of the lower housing (20) is provided with a central shaft sleeve (21), the central shaft (11) is sleeved into the central shaft sleeve (21) ), so that the upper shell (10) and the lower shell (20) can follow the central shaft (11) and the central shaft sleeve (21) to generate mutual The pivoting of the upper shell (10) and the side walls of the lower shell (20) are fixed with a hinge piece (12) (22) protruding to the side, wherein the central shaft (11) A tapered roller bearing (30) is installed on the upper housing (20), and a tapered bearing sleeve (40) is sleeved above the center sleeve (21) of the lower shell (20). The tapered bearing sleeve (40) is connected to the tapered roller The sub-bearing (30) cooperates so that the inclination of the inner wall of the tapered bearing sleeve (40) can be the same as the inclination of the surface of the tapered roller bearing (30). The inner wall is directly sleeved with the tapered bearing sleeve (40) that matches the tapered roller bearing (30), which can ensure that the upper shell (10) and the lower shell (20) are using the The accuracy of the coaxial connection between the central shaft (11) and the central shaft sleeve (21) as a set can effectively reduce the friction loss between the central shaft (11) and the central shaft sleeve (21), so that the center The shaft (11) can have a higher bearing capacity and prolong its service life.

The present invention provides an automatic correction hinge structure, wherein the tapered roller bearing (30) is sequentially provided with an inner ring (31), a roller (32) and a cage (33) from the inside to the outside. 31) is sleeved on the central shaft (11) so that its top can be fixedly connected to the bottom of the upper casing (10), and the height of the inner ring (31) is higher than that of the cage (33) )the height of.

The present invention provides an automatic correction hinge structure, wherein a plurality of fixing holes (13) (23) are provided on the hinge pieces (12) (22).
