Description

Technical Field

[0001] The utility model relates to the technical field of protective door hinges, in particular to a safety protective door hinge. Background Technique

[0002] A hinge, also known as a hinge joint, is a mechanical device used to connect two solids and allow rotation between them. Hinges play an important role in furniture hardware fittings. A hinge usually includes a first hinge leaf, a second hinge leaf, and a pin shaft connecting the second hinge leaf and the first hinge leaf. Usually, the first hinge leaf is used to be fixed on a column, a vehicle frame, or a wall, and the second hinge leaf is connected and fixed to a door, so that the door rotates around the pin shaft and has two states of opening or closing.

[0003] When installing a hinge, it is necessary to open a predetermined installation groove and a screw groove on the protective door and the wall. However, during installation, often due to the misalignment between the screw groove and the bolt position, it is necessary to re-open a corresponding screw groove again, which affects the aesthetics of the protective door and the wall and the installation efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a safety protective door hinge to solve the problem that due to the misalignment between the screw groove and the bolt position, it is necessary to re-open a corresponding screw groove again, which affects the aesthetics of the protective door and the wall and the installation efficiency as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a safety protective door hinge, including a hinge body. A connecting piece is connected to the inner side of the hinge body, and a pin shaft is connected to the inner side of the connecting piece. Adjusting grooves are opened on the outer surfaces of the upper and lower ends of the hinge body. A sliding groove is opened on the inner side of the adjusting groove, and a sliding block is slidably connected to the inner side of the sliding groove. An adjusting block is fixedly connected to the outer surface of the sliding block, and a bolt is rotatably connected to the inner side of the adjusting block.

[0006] Preferably, a connecting groove is opened on the upper surface of the hinge body. A spring is fixedly connected to the inner side of the connecting groove, and a protective plate is fixedly connected to the upper surface of the spring. Guide grooves are opened on both sides of the upper end of the hinge body close to the connecting groove, and a connecting strip is slidably connected to the inner side of the guide groove. A limiting block is fixedly connected to the lower surface of the connecting strip.

[0007] Preferably, there are two groups of the hinge bodies. The adjusting groove is an elliptical groove, and multiple groups of the adjusting grooves are opened on the outer surface of the hinge body. Its function is to connect one group of the hinge bodies to the wall and the other group of the hinge bodies to the protective door.

[0008] Preferably, the slide groove is a rectangular groove, and the sliders are in two groups. The adjustment block is fixedly connected between the two groups of sliders, and the adjustment block is slidably connected to the inner side of the adjustment groove. Its function is to make the position of the adjustment block fine-tuned by sliding the adjustment block to the inner side of the adjustment groove, so that the adjustment block corresponds to the predetermined screw groove, which is convenient for the installation of the hinge body.

[0009] Preferably, a screw groove is provided on the inner side of the adjusting block, and the bolt is rotatably connected to the inner side of the screw groove, and its function is to rotate the bolt on the inner side of the adjusting block so that the two sets of hinge bodies can be fixedly installed on the wall and the protective door.

[0010] Preferably, the connecting groove is a cylindrical groove, the spring is in a spiral shape, the lower end of the spring is fixedly connected to the inner side of the connecting groove, and the upper end of the spring is fixedly connected to the protective plate. Its function is to pull the protective plate to the uppermost end of the hinge body so that the adjustment block on the hinge body is exposed, and then the hinge body is fixedly connected to the wall or installed on the door by bolts. By relaxing the control of the protective plate, the protective plate is reset under the elastic action of the spring, thereby covering the adjustment block, so that the hinge body and the protective plate become a whole, thereby increasing the aesthetics of the hinge body.

[0011] Preferably, the guide groove is a rectangular groove, the connecting strip is strip-shaped, the connecting strip is slidably connected to the inner side of the guide groove, the connecting strip is in two groups, the connecting strip is fixedly connected to the protective plate, and the limit block is block-shaped, and its function is to make the connecting strip slide on the inner side of the guide groove. At the same time, since the limit block also slides on the inner side of the guide groove, and the limit block is fixedly connected to the connecting strip, the connecting strip slides on the inner side of the guide groove, but will not separate from the guide groove, so that the protective plate slides on the outer surface of the hinge body and will not separate from the hinge body.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By installing the two sets of hinge bodies into the installation grooves opened in the protective door and the wall respectively, and then sliding the adjustment block on the inner side of the adjustment groove so that the adjustment block corresponds to the reserved screw groove, the position of the adjustment block can be adjusted, and then the adjustment block and the reserved screw groove are connected by rotating the bolt, so that the hinge body is fixedly connected to the installation grooves opened in the protective door and the wall, thereby preventing the screw groove from not corresponding to the position of the adjustment block, thereby requiring re-grooving, affecting the installation efficiency of the hinge body.

[0014] 2. Before installing the hinge body onto the wall or the protective door, by pulling the protective plate to the uppermost end of the hinge body, the adjustment block on the hinge body is exposed. After fixing and connecting the hinge body to the wall or the installation door with bolts, by releasing the control of the protective plate, under the elastic action of the spring, the protective plate resets, covering the adjustment block, making the hinge body and the protective plate an integral whole, thereby increasing the aesthetic appearance of the hinge body. At the same time, it also prevents dust from entering the inside of the adjustment block, causing corrosion of the bolts. BRIEF DESCRIPTION OF THE DRAWINGS
