Description

Technical Field

[0001] The utility model belongs to the technical field of hardware parts and relates to a hinge, in particular to an anti-bending hinge. Background Art

[0002] A hinge, also known as a hinge or a hinge, is a widely used connecting device, mainly used to connect two objects and allow them to rotate relative to each other.

[0003] In actual use, some door panels and other components are too heavy, causing the hinges to bend and deform, affecting opening and closing. In severe cases, the hinges break directly, so it is necessary to increase the supporting strength of the hinges. Summary of the invention

[0004] The purpose of the utility model is to provide a smooth-running anti-bending hinge in view of the above-mentioned problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: an anti-bending hinge, characterized in that it includes a hinge component A and a hinge component B that are hingedly connected to each other, the hinge component A is provided with two symmetrically arranged arc-shaped guide parts, the hinge component B is provided with a guide component, and the guide component is arranged between the arc-shaped guide parts, the guide component is provided with a mounting seat, the mounting seat is provided with a mounting cavity, and a plurality of rolling columns are arranged in the mounting cavity, the side walls of the rolling columns are also provided with guide blocks, and arc springs are arranged between the guide blocks.

[0006] In the above-mentioned anti-bending hinge, guide balls are provided at both ends of the rolling column, and guide grooves are provided on the arc-shaped guiding parts.

[0007] In the above-mentioned anti-bending hinge, the hinge component A is provided with an extension portion, and the hinge component A and the hinge component B are both provided with a plurality of bolt mounting holes.

[0008] In the above-mentioned anti-bending hinge, a sealing cushion is provided between the guide portion and the guide assembly.

[0009] Compared with the prior art, the anti-bending hinge clamps the anti-bending hinge through the arc-shaped guide part to increase the axial supporting force of the hinge, so that the hinge can be suitable for application scenarios with greater gravity. The friction force is reduced by the rolling columns and guide balls. The evenly distributed rolling columns make the force more uniform when the hinge rotates. The sealing pad increases the sealing performance and reduces the maintenance of the hinge. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0016] like Figure 1 , 2 As shown in Figures 3 and 4, the anti-bending hinge is characterized in that it comprises a hinge assembly A5 and a hinge assembly B1 which are hingedly connected to each other, the hinge assembly A5 is provided with two symmetrically arranged arc guide parts 4, the hinge assembly B1 is provided with a guide assembly 3, and the guide assembly 3 is arranged between the arc guide parts 4, the guide assembly 3 is provided with a mounting seat 11, the mounting seat 11 is provided with a mounting cavity 9, and the mounting cavity 9 has a plurality of rolling columns 12 in the inside, guide blocks 13 are further provided on the side walls of the rolling columns 12, and arc springs 14 are provided between the guide blocks 13, when the hinge rotates, the plurality of rolling columns 12 are squeezed and stacked, and under the support of the arc springs 14, the rolling columns 12 maintain the same spacing, and the strength of the hinge installation is enhanced through the support of the arc guide part 4 and the guide assembly.

[0017] Preferably, guide balls 10 are provided at both ends of the rolling column 12, and guide grooves 8 are provided on the arc-shaped guide portion 4. The balls increase the support and damping of the hinge, making the hinge open and close more smoothly.

[0018] Preferably, an extension portion 7 is provided on the hinge assembly A5, and a plurality of bolt mounting holes 6 are provided on both the hinge assembly A5 and the hinge assembly B1. The extension portion 7 increases the installation area of ​​the hinge assembly and increases the strength after installation.

[0019] Preferably, a sealing gasket 2 is provided between the guide portion and the guide assembly 3, and the sealing gasket 2 prevents the lubricating grease in the guide assembly 3 from being lost quickly, thereby increasing the service life.

[0020] The specific embodiments described herein are merely examples of the spirit of the present invention. A person skilled in the art of the present invention may make various modifications or additions to the specific embodiments described or replace them in a similar manner, but this will not deviate from the spirit of the present invention or exceed the scope defined in the appended claims.

[0021] Although the present invention uses more terms such as hinge assembly B1, sealing cushion 2, guide assembly 3, arc-shaped guide portion 4, hinge assembly A5, bolt mounting hole 6, extension portion 7, guide groove 8, mounting cavity 9, guide ball 10, mounting seat 11, rolling column 12, guide block 13, arc-shaped spring 14, etc., it does not exclude the possibility of using other terms. The use of these terms is only for the purpose of more conveniently describing and explaining the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.
