Description

Technical Field

[0001] The utility model relates to the technical field of hinge mechanisms, in particular to a high-strength hinge mechanism for a composite door. Background Art

[0002] A hinge mechanism, also known as a hinge, is a connecting piece that is arranged using a geometric shape. It is mainly used to connect two main bodies and enable them to rotate relative to each other while maintaining a close fit with each other.

[0003] At present, the hinge mechanism realizes the rotational connection between two parts through its special structure and design, ensuring the stability and smoothness of the connection. The hinge mechanism is an important connector and transmission component, and is widely used in home and industrial fields. Through its special structure and design, the hinge mechanism realizes the smooth opening and closing and stable connection of objects, bringing convenience to people's life and work.

[0004] However, the current composite door hinge mechanism still has the following disadvantages when in use. When in use, wear is likely to occur between the rotating shaft and the sleeve, which in turn causes shaking at the connection, causing the composite door to tilt when closed or make a loud closing noise, thereby greatly reducing the service life of the hinge. At the same time, its connection strength is low and it is prone to deformation after long-term use. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a high-strength hinge mechanism for a composite door, so as to solve the technical problems that the existing high-strength hinge mechanism for a composite door is prone to wear between the rotating shaft and the sleeve during use, which in turn causes shaking at the connection, causing the composite door to tilt when closed or making a loud closing noise, thereby greatly reducing the service life of the hinge, and at the same time, the connection strength is low and it is prone to deformation after long-term use.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A high-strength hinge mechanism for a composite door, comprising: a first hinge plate and a second hinge plate. A base is provided at the top of the first hinge plate. A sleeve is fixedly installed on the top of the base. A first insertion hole is opened at one end of the sleeve, and a second insertion hole is opened at the other end of the sleeve. A first connecting rod and a second connecting rod are fixedly installed on the outer wall of one side of the second hinge plate. A rotating column is fixedly installed at the other end of the second connecting rod. A limiting sleeve is fixedly installed at the other end of the first connecting rod. The limiting sleeve and the sleeve are connected through a connecting mechanism. The connecting mechanism includes a lubricating ball, a second bearing, a first convex column, a circular plate, a limiting ring and a second convex column. The first convex column is movably inserted into the inside of the limiting sleeve. The lubricating ball is movably arranged in the gap between the circular plate and the outer wall of one side of the sleeve. The limiting ring is fixedly installed on the inner wall of the bottom of the second insertion hole. The outer ring of the second bearing is clamped and embedded in the second insertion hole. The second convex column is inserted into the inner ring of the second bearing in a limited manner.

[0008] Further, a first installation hole is opened inside the first hinge plate, and a second installation hole is opened inside the second hinge plate.

[0009] Further, insertion rods are fixedly installed at both ends of the rotating column. A first bearing is embedded in the first insertion hole. The other end of the insertion rod is inserted into the inner ring of the first bearing in a limited manner.

[0010] Further, the first convex column is fixedly installed on the outer wall of one side of the circular plate, and the second convex column is fixedly installed on the outer wall of the other side of the circular plate.

[0011] Further, annular ball grooves are opened on the outer walls of one side of the circular plate and the sleeve. The lubricating ball is movably arranged in the upper and lower annular ball grooves.

[0012] The beneficial effects of the present utility model:

[0013] By providing a connecting mechanism, three connecting rods are used to connect the first hinge plate and the second hinge plate, so that the connection strength is higher, the force is more uniform, and deformation is not likely to occur. At the same time, the second convex column and the second insertion hole are connected by a second bearing, and the insertion rod and the first insertion hole are connected by a first bearing, which greatly reduces the friction force and is conducive to the relative rotation between the two hinge plates, enabling people to rotate the door panel with less force, making the use of the hinge smoother. At the same time, the circular plate and the sleeve are connected by a lubricating ball, which can prevent face-to-face friction between the circular plate and the sleeve, reduce wear, and greatly improve the service life of the hinge.

A rotating column 9 is fixedly installed at the other end of the second connecting rod. A limiting sleeve 8 is fixedly installed at the other end of the first connecting rod 3. The limiting sleeve 8 is connected to the sleeve 5 through a connecting mechanism. The connecting mechanism includes a lubricating ball 13, a second bearing 14, a first convex column 6, a circular plate 7, a limiting ring 15 and a second convex column 11. The first convex column 6 is movably inserted into the inside of the limiting sleeve 8. The lubricating ball 13 is movably arranged in the gap between the circular plate 7 and the outer wall of one side of the sleeve 5. A limiting ring 15 is fixedly installed on the inner wall of the bottom of the second insertion hole. The outer ring of the second bearing 14 is clamped and embedded in the second insertion hole.

When in use, a bearing or a lubricating ball 13 can also be provided at the connection between the convex column and the limiting sleeve 8 to reduce friction and greatly improve the service strength of the hinge.

[0026] Specifically, by providing a connecting mechanism, three groups of connecting rods are used to connect the first hinge plate 1 and the second hinge plate 2, so that the connection strength is higher, the force is more uniform, and deformation is not likely to occur. At the same time, the second convex column 11 and the second insertion hole are connected by the second bearing 14, and the insertion rod 10 and the first insertion hole are connected by the first bearing 12, which greatly reduces the friction force and is beneficial to the relative rotation between the two groups of hinge plates, enabling people to rotate the door panel with a smaller force, making the use of the hinge smoother.

[0027] In this embodiment, a first mounting hole is formed inside the first hinge piece 1, and a second mounting hole is formed inside the second hinge piece 2.

[0028] Specifically, during use, the first hinge piece 1 is fixedly installed on the door frame by inserting a screw into the first mounting hole, and the second hinge piece 2 is fixedly installed on the door panel by inserting a screw into the second mounting hole. The structure is simple and easy to operate.

[0030] Specifically, during use, the sliding friction between the plugging rod 10 and the first plugging hole can be greatly reduced, which is beneficial to the better use of the hinge mechanism.

[0031] In summary, compared with the prior art, the hinge mechanism has at least the following beneficial effects: by providing a connection mechanism, three groups of connecting rods are used to connect the first hinge piece 1 and the second hinge piece 2, so that the connection strength is higher, the force is more uniform, and deformation is not likely to occur. At the same time, the second convex column 11 and the second plugging hole are connected by a second bearing 14, and the plugging rod 10 and the first plugging hole are connected by a first bearing 12, which greatly reduces the frictional force and is beneficial to the relative rotation between the two groups of hinge pieces, enabling people to rotate the door panel with a smaller force, making the use of the hinge smoother. At the same time, the circular plate 7 and the sleeve 5 are connected by a lubricating ball 13, which can prevent face-to-face friction between the circular plate 7 and the sleeve 5, reduce wear, and greatly improve the service life of the hinge.
