[0021] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] Combine the following Figures 1 to 3 The utility model is described in detail.

[0023] A self-positioning structure for door hinge installation includes a main body 1, a through groove 101 is provided in the middle of the main body 1, a hinge block 2 is connected to the middle of the main body 1, a hinge shaft 201 is provided at one end of the hinge block 2, the hinge shaft 201 cooperates with the through groove 101, positioning slide rails 102 are provided on the upper and lower sides of the middle of the main body 1, positioning rods 202 are provided on the upper and lower sides of one end of the hinge block 2 close to the hinge shaft 201, the positioning rod 202 cooperates with the positioning slide rail 102, a limiting groove 1021 is provided on one side of the inner wall of the positioning slide rail 102, a limiting component is provided on one side of the positioning rod 202, the limiting component cooperates with the limiting groove 1021, the limiting component elastically contracts along the groove, and the positioning slide rail 102 is an arc groove that cooperates with the arc of the through groove 101.

[0024] First, the hinge block 2 is connected to the through slot 101 of the body 1 through the hinge shaft 201, so that the hinge block 2 can be flexibly deflected in the body 1, and then the hinge block 2 is connected to the door, so that the door can be deflected to realize the opening and closing action.

[0025] However, when the existing hinge block 2 is installed, a gap is usually left between the hinge block 2 and the inner wall of the main body 1 to avoid wear and noise. However, due to the gap, the spacing cannot be accurately controlled during installation, so that after the door is installed, there will be a certain error in the height position of the door. Therefore, when the hinge block 2 is installed, the positioning rods 202 near the upper and lower sides of the hinge shaft 201 will be embedded in the positioning slide rail 102. The length of the positioning rod 202 is matched with the positioning slide rail 102, so that there will be no error in the height of the hinge block 2, which will affect the installation accuracy of the door.

[0026] Furthermore, the positioning slide 102 also includes an extrusion layer 1022, which is arranged on one side of the inner wall of the positioning slide 102, and the extrusion layer 1022 is connected to one side of the inner wall of the positioning slide 102 where a limiting groove 1021 is arranged, and the extrusion layer 1022 is made of elastic rubber, and the extrusion layer 1022 is arranged in a strip shape, and the limiting assembly includes a positioning rod 202, a contraction groove 2021 and a limiting rod 2022, the positioning rod 202 is a convex rod arranged on the upper and lower sides of one end of the hinge block 2 close to the hinge shaft 201, the contraction groove 2021 is arranged on one side of the positioning rod 202, the limiting rod 2022 is connected to the contraction groove 2021, the contraction groove 2021 is a rectangular groove arranged on one side of the positioning rod 202, the limiting rod 2022 is a rod body whose one side is connected to the contraction groove 2021 by a spring, and the side of the limiting rod 2022 connected to the spring is rectangular.

[0027] At the same time, when the door is deflected and opened, the positioning rod 202 will be driven to slide along the positioning slide rail 102. During the sliding process, the limiting rod 2022 connected to the limiting groove 1021 on one side will be pressed against the extrusion layer 1022. Because of the continuous pressure during the deflection process, it cannot quickly pop out and fit into the limiting groove 1021, so that the positioning rod 202 will slide smoothly along the positioning slide rail 102. If the door is opened and closed to a suitable angle and the switching action is stopped at the same time, the limiting rod 2022 will continue to press on the extrusion layer 1022 due to the return force of the spring, so that it is squeezed into the limiting groove 1021 and deformed, thereby forming a certain groove to limit and fit the protruding part of the limiting rod 2022 to a certain extent, so that it will not close automatically, so that when transporting objects, there is no need for continuous manual control, thereby avoiding the door from closing automatically.

[0028] The following is a specific implementation process of the utility model. First, the hinge block 2 is connected to the through groove 101 of the main body 1 through the hinge shaft 201, so that the hinge block 2 can be flexibly deflected in the main body 1, and then the hinge block 2 is connected to the door, so that the door can be deflected to realize the opening and closing action. However, when the existing hinge block 2 is installed, a gap is usually left between the hinge block 2 and the inner wall of the main body 1 to avoid wear and noise. However, due to the gap, the spacing cannot be accurately controlled during installation, so that after the door is installed, there will be a certain error in the height position of the door. Therefore, when the hinge block 2 is installed, the positioning rods 202 near the upper and lower sides of the hinge shaft 201 will be embedded in the positioning slide rails 102. The length of the positioning rods 202 cooperates with the positioning slide rails 102, so that the height of the hinge block 2 will not have an error, which affects the installation accuracy of the door. At the same time, when the door is installed When the deflection switch is performed, the positioning rod 202 will be driven to slide along the positioning slide rail 102. During the sliding process, the limiting rod 2022 connected to the limiting groove 1021 on one side will be pressed against the extrusion layer 1022. Because of the continuous pressure during the deflection process, it cannot quickly pop out and fit into the limiting groove 1021, so that the positioning rod 202 will slide smoothly along the positioning slide rail 102. If the door switch is at a suitable angle and the switch action is stopped at the same time, the limiting rod 2022 will continue to apply pressure to the extrusion layer 1022 due to the return force of the spring, so that it is squeezed into the limiting groove 1021 and deformed, thereby forming a certain groove to limit and fit the protruding part of the limiting rod 2022 to a certain extent, so that it will not close automatically, so that when transporting objects, there is no need for continuous manual control, thereby avoiding the door from closing automatically.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
