Description

Technical Field

[0001] The utility model relates to the technical field of hinges, and specifically, to a three-dimensional hinge. Background Art

[0002] A three-dimensional hinge is a conventional hardware part, commonly known as a hinge, which is used for rotatably connecting two components. The rotation of a door is basically achieved by hinges. Traditional hinges include a pair of metal blades, a fan blade and a frame blade. The fan blade is fixed on the door leaf, and the frame blade is fixed on the door frame.

[0003] When the existing three-dimensional hinges are installed, they are fixed by screws. Generally, the existing hinges do not have a structure for positioning the screws. When a person fixes the hinge with screws, if the screws are inclined, the screws will be skewed at the installation holes of the hinge after the screws are installed, thereby affecting the fixing effect of the hinge and easily causing the hinge to become loose. For this reason, a three-dimensional hinge is needed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a three-dimensional hinge to solve the problem that generally, the existing hinges do not have a structure for positioning the screws in the prior art. When a person fixes the hinge with screws, if the screws are inclined, the screws will be skewed at the installation holes of the hinge after the screws are installed, thereby affecting the fixing effect of the hinge and easily causing the hinge to become loose.

[0005] The utility model provides the following technical solution: a three-dimensional hinge, including a first hinge. A second hinge is rotatably arranged at the side end of the first hinge. Insertion holes are respectively opened at the top end and the bottom end of the first hinge. A fixing component is arranged between the top end and the bottom end of the first hinge. A positioning component for positioning screws is arranged at the side end of the fixing component.

[0006] Preferably, as the above technical solution, the fixing component includes a first fixing plate, which is located at the top end of the first hinge. A hollow rod is fixedly connected to the bottom end of the first fixing plate. A round plate is inserted into the interior of the hollow rod. A round rod is fixedly connected to the bottom end of the round plate. A second fixing plate is fixedly connected to the bottom end of the round rod. A spring is sleeved on the outer end of the round rod, and the spring is located inside the hollow rod.

[0007] Preferably, as the above technical solution, the bottom end of the spring is fixedly connected to the inner bottom end of the hollow rod, and the top end of the spring is fixedly connected to the bottom end of the round plate.

[0008] Preferably, as the above technical solution, insertion rods are fixedly connected to the bottom end of the first fixing plate and the top end of the second fixing plate respectively, and each insertion rod is adapted to each insertion hole.

[0009] Preferably, as the above technical solution, the positioning component includes two groups of limiting plates, which are respectively fixedly connected to the side ends of the first fixing plate and the second fixing plate. A number of limiting grooves are provided at the side ends of each group of limiting plates, and a number of positioning plates are fixedly connected to the side ends of each group of limiting plates.

[0010] Preferably, as the above technical solution, the outer shape of each positioning plate is arc-shaped.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] With the setting of the fixing component in the present utility model, by pulling the first fixing plate and the second fixing plate, the distance between the two plates is increased. At this time, the circular plate and the circular rod move within the hollow rod, and the circular plate presses against the spring to contract. At this time, the two insertion rods are located at the side ends of the two insertion holes, that is, the first fixing plate is located at the top of the first hinge, and the second fixing plate is located at the bottom of the second hinge. After releasing the first fixing plate and the second fixing plate, the spring rebounds with the circular plate, driving the second fixing plate to move, shortening the distance between the first fixing plate and the second fixing plate. At this time, the two insertion rods are respectively inserted into the two insertion holes, facilitating the installation of the positioning component and also facilitating the disassembly of the positioning component. With the setting of the positioning component, each limiting plate is located at the side end of the first hinge, and each limiting groove is exactly opposite to each installation hole at the side end of the first hinge. By aligning the screw with the installation hole, the end side of the screw leans against the inner wall of the positioning plate, providing a supporting effect on the screw, keeping the screw straight and not inclined or skewed. Then, by using a screwdriver to install the screw at the installation hole on the side end of the first hinge, the situation of the screw being skewed at the installation hole of the first hinge can be avoided, thus preventing the fixing effect of the hinge from being affected and the hinge from becoming loose.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0019] As shown in Figures 1-4 the figure, the present utility model provides a technical solution: a three-dimensional hinge, including hinge one 1, hinge two 102 is rotatably arranged at the side end of hinge one 1, jacks 101 are provided at both the top and bottom ends of hinge one 1, a fixing component is arranged between the top and bottom ends of hinge one 1, and a positioning component for positioning screws is arranged at the side end of the fixing component. The setting of the fixing component can facilitate the installation or disassembly of the positioning component at the side end of hinge one 1. Through the setting of the positioning component, the screw can be supported, so that the screw is in a straight state and will not tilt or skew. At this time, the screw is installed at the installation hole at the side end of hinge one 1 through a screw gun. Therefore, the situation that the screw is skewed at the installation hole of hinge one 1 can be avoided, thereby avoiding affecting the fixing effect of the hinge and preventing the hinge from loosening.

[0020] As an implementation manner in this embodiment, as shown in Figure 2 and Figure 3As shown in the figure, the fixing component includes a first fixing plate 2, and the first fixing plate 2 is located at the top of the first hinge 1. The bottom end of the first fixing plate 2 is fixedly connected with a hollow rod 201. A circular plate 202 is inserted into the interior of the hollow rod 201. The bottom end of the circular plate 202 is fixedly connected with a circular rod 203. The bottom end of the circular rod 203 is fixedly connected with a second fixing plate 205. A spring 204 is sleeved on the outer end of the circular rod 203. The spring 204 is located inside the hollow rod 201. The bottom end of the spring 204 is fixedly connected to the inner bottom end of the hollow rod 201, and the top end of the spring 204 is fixedly connected to the bottom end of the circular plate 202. The bottom end of the first fixing plate 2 and the top end of the second fixing plate 205 are both fixedly connected with insertion rods 206. Each insertion rod 206 is adapted to each jack 101. During implementation, by pulling the first fixing plate 2 and the second fixing plate 205, the distance between the two plates is increased. At this time, the circular plate 202 and the circular rod 203 move inside the hollow rod 201, and the circular plate 202 presses against the spring 204 for contraction. At this time, the two insertion rods 206 are located at the side ends of the two jacks 101, that is, the first fixing plate 2 is located at the top of the first hinge 1, and the second fixing plate 205 is located at the bottom of the second hinge 102. At this time, after releasing the first fixing plate 2 and the second fixing plate 205, the spring 204 rebounds against the circular plate 202, and at this time drives the second fixing plate 205 to move, so that the distance between the first fixing plate 2 and the second fixing plate 205 is shortened. At this time, the two insertion rods 206 are respectively inserted into the two jacks 101. At this time, it is convenient to complete the installation of the positioning component, and it is also convenient to disassemble the positioning component.

[0021] As an implementation method in this embodiment, as Figure 4 shown, the positioning component includes two groups of limiting plates 3. The two groups of limiting plates 3 are respectively fixedly connected to the side ends of the first fixing plate 2 and the second fixing plate 205. A number of limiting slots 301 are provided at the side ends of each group of limiting plates 3. A number of positioning plates 302 are fixedly connected to the side ends of each group of limiting plates 3. The outer shape of each positioning plate 302 is arc-shaped. During implementation, after the fixing component is installed, at this time each limiting plate 3 is located at the side end of the first hinge 1, and each limiting slot 301 is exactly opposite to each installation hole at the side end of the first hinge 1. At this time, by aligning the screw with the installation hole, the side end of the head of the screw leans against the inner wall of the positioning plate 302, so as to support the screw, making the screw in a straight state and not inclined or skewed. At this time, the screw is installed in the installation hole at the side end of the first hinge 1 through a screwdriver. Therefore, the situation of the screw being skewed at the installation hole of the first hinge 1 can be avoided, thereby avoiding affecting the fixing effect of the hinge and preventing the hinge from loosening.

[0022] Working principle: By pulling the first fixing plate 2 and the second fixing plate 205, the distance between the two plates is increased. At this time, the circular plate 202 and the circular rod 203 move within the hollow rod 201, and the circular plate 202 presses against the spring 204 to contract. At this time, the two insertion rods 206 are located at the side ends of the two insertion holes 101, that is, the first fixing plate 2 is located at the top of the first hinge 1, and the second fixing plate 205 is located at the bottom of the second hinge 102. After releasing the first fixing plate 2 and the second fixing plate 205, the spring 204 pushes the circular plate 202 to rebound, driving the second fixing plate 205 to move, shortening the distance between the first fixing plate 2 and the second fixing plate 205. At this time, the two insertion rods 206 are respectively inserted into the two insertion holes 101, facilitating the installation of the positioning component and also facilitating the disassembly of the positioning component. At this time, each limiting plate 3 is located at the side end of the first hinge 1, and each limiting groove 301 is exactly opposite to each installation hole at the side end of the first hinge 1. By aligning the screw with the installation hole, the end side of the screw leans against the inner wall of the positioning plate 302, providing a supporting effect on the screw, keeping the screw straight without tilting or skewing. Then, using a screwdriver to install the screw at the installation hole on the side end of the first hinge 1 can avoid the screw from being skewed at the installation hole of the first hinge 1, thus preventing the influence on the fixing effect of the hinge and avoiding the loosening of the hinge. Finally, after the screw installation is completed, by pulling the first fixing plate 2 and the second fixing plate 205, the limiting plate 3 is disassembled from the side end of the hinge, enabling the hinge to rotate three-dimensionally conveniently.

[0023] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
