Description

Technical Field

[0001] This utility model relates to the field of door hinge installation technology, specifically a novel and efficient door hinge installation structure. Background Technology

[0002] The door hinge is the core component connecting the door body and the door frame. It is responsible for supporting the weight of the door and enabling smooth opening and closing. Door hinges are mostly made of 304 stainless steel, which has strong corrosion resistance, can withstand salt spray tests for more than 48 hours, has moderate cost, and has a long service life.

[0003] Existing old-style door hinges require welding door hinge brackets to the door panel, and after welding, the weld points on the door panel need to be ground, which wastes time. To address this, we have designed a new and efficient door hinge installation structure to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a novel and efficient door hinge mounting structure to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a novel and efficient door hinge installation structure, including a door panel and a door hinge body inserted into the top of the door panel. The bottom end of the door hinge body is integrally formed and inclinedly provided with a fixing pin. The other end of the fixing pin passes through one side of the door panel. A step is fixedly sleeved on the door hinge body. A spring is provided at the bottom of the step. The spring is movably sleeved on the door hinge body, and both ends of the spring are located inside the door panel.

[0006] Furthermore, the top, one side, and interior of the door panel are respectively provided with interconnected fixing openings, limiting openings, and mounting cavities. The door hinge body is slidably inserted into the fixing opening, the fixing pin is slidably inserted into the limiting opening, the step abuts against the top wall of the mounting cavity, and its diameter is larger than the diameter of the fixing opening. The end of the spring away from the step abuts against the inner side wall of the mounting cavity.

[0007] Furthermore, the spring is made of 304 stainless steel.

[0008] Furthermore, the top of the door panel is provided with an operating opening that communicates with the mounting cavity, and the diameter of the operating opening is larger than the diameter of the door hinge.

[0009] Furthermore, an inflection point is provided between the door hinge and the fixing pin.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: by inserting the fixing pin into the limiting port from the operating port and then through it, the end of the spring away from the step is stuck in the inner side wall of the mounting cavity. Then, the door hinge body is fully inserted into the operating port and then through the fixing port. Since the diameter of the step is larger than the diameter of the fixing port, the door hinge body is held against the step by the rebound force of the compressed spring, so that the step holds against the fixing port, allowing the spring to extend and retract freely. The whole process does not require welding or grinding, and can achieve the effect of efficient and fast installation of the door hinge device. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4 This utility model provides a technical solution: a novel and efficient door hinge installation structure, including a door panel 1 and a door hinge body 2 inserted into the top of the door panel 1. The bottom end of the door hinge body 2 is integrally formed and inclinedly provided with a fixing pin 3. The other end of the fixing pin 3 passes through one side of the door panel 1. A step 5 is fixedly sleeved on the door hinge body 2. A spring 4 is provided at the bottom of the step 5. The spring 4 is movably sleeved on the door hinge body 2, and both ends of the spring 4 are provided inside the door panel 1. The top, one side and the inside of the door panel 1 are respectively provided with a fixed opening 6, a limiting opening 7 and an installation cavity 8 that are interconnected. The door hinge 2 is slidably inserted into the fixed opening 6, the fixing pin 3 is slidably inserted into the limiting opening 7, the step 5 abuts against the top wall of the installation cavity 8 and the diameter is larger than the diameter of the fixed opening 6, the end of the spring 4 away from the step 5 abuts against the inner side wall of the installation cavity 8, and the top of the door panel 1 is also provided with an operating opening 9 that is connected to the installation cavity 8. The diameter of the operating opening 9 is larger than the diameter of the door hinge 2.

[0015] In practice, firstly, a drilling tool is used to drill through the fixed port 6, the limiting port 7, and the operating port 9 on the same plane, so that the limiting port 7 and the operating port 9 are concentric. Then, the fixing pin 3 enters the limiting port 7 along the operating port 9 and passes through. At this time, the end of the spring 4 away from the step 5 is stuck on the inner wall of the mounting cavity 8 and located on one side of the limiting port 7. Then, the spring 4 is compressed so that the door hinge body 2 is fully inserted into the operating port 9 and then passes through the fixed port 6. Since the diameter of the step 5 is larger than the diameter of the fixed port 6, the door hinge body 2 is pressed against the step 5 by the rebound force of the spring 4 being compressed, so that the step 5 presses against the fixed port 6, and the spring 4 can extend and retract freely, so that the door hinge device can be installed efficiently and quickly.

[0016] See Figure 1-4 Spring 4 is made of 304 stainless steel. 304 stainless steel can effectively slow down the corrosion rate of spring 4, thereby helping to extend the service life and stability of spring 4.

[0017] See Figure 1-4 An inflection point 10 is provided between the door hinge body 2 and the fixing pin 3. This facilitates the positioning of the door hinge body 2 and can further improve the installation speed.

[0018] Working principle: In use, firstly, the fixing port 6, the limiting port 7, and the operating port 9 are drilled through to the same plane using a drilling tool, so that the limiting port 7 and the operating port 9 are concentric. Then, the door hinge 2 enters the limiting port 7 from the inflection point 10 along the operating port 9 and passes through. At this time, the end of the spring 4 away from the step 5 is stuck on the inner wall of the mounting cavity 8 and located on one side of the limiting port 7. Then, the spring 4 is compressed so that the door hinge 2 is fully inserted into the operating port 9 and then passes through the fixing port 6. Since the diameter of the step 5 is larger than the diameter of the fixing port 6, the door hinge 2 is pressed against the step 5 by the rebound force of the spring 4 being compressed, so that the step 5 presses against the fixing port 6, allowing the spring 4 to extend and retract freely, thus efficiently and quickly installing the door hinge device.
