Description

Technical Field

[0001] This utility model relates to the field of door and window accessories technology, and in particular to a door and window hinge that prevents the door from moving on its own when opened. Background Technology

[0002] Hinges are primarily installed on doors and windows, while cabinet and furniture doors are more commonly fitted with them. Classified by material, they are mainly divided into stainless steel hinges and iron hinges. To provide a better user experience, damping hinges (also known as buffer hinges) have emerged. Their characteristic is a buffering function when the cabinet door closes, minimizing the noise generated by the door colliding with the cabinet body. In existing hinges, to further reduce noise and prevent the hinge from shifting on its own, some hinges incorporate dampers within the hinge itself. These dampers generate resistance during the opening motion, slowing down the opening speed and preventing sudden movement or self-shifting. This design allows the hinge to gradually decelerate during operation, avoiding the impact and damage caused by sudden closing or opening.

[0003] Existing technologies have the following problems:

[0004] After extensive searching, it was found that the patent application with application number CN202021294496.5 discloses a damping hinge. During use, the damper will wear and loosen due to forceful closing. After the damper wears and loosens, the spring will lose its elasticity, causing the door and window to be unable to close slowly. If the damper is not replaced in time, the door and window will suddenly move or move on its own during the opening process.

[0005] To address this issue, we proposed a door and window hinge design to prevent the hinge from sliding on its own when opened, thus resolving the aforementioned drawbacks. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a door and window hinge that prevents the hinge from sliding on its own when opened.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a door and window hinge to prevent the hinge from moving on its own when opened, comprising a damping hinge body, wherein the damping hinge body has a damper mounting groove, and the side wall of the damper mounting groove has a slot, and a locking block is engaged inside the slot. A damper maintenance cover plate is detachably installed inside the damper mounting groove. One side surface of the locking block is fixedly connected to the surface of the damper maintenance cover plate. A positioning hole is opened on one side surface of the damper maintenance cover plate, and a positioning rod is inserted into the positioning hole. A storage groove is opened on one side surface of the damping hinge body, and a fixing plate is provided inside the storage groove. A pull ring is welded to one side surface of the fixing plate. One end of the positioning rod extends into the storage groove and is fixedly connected to the other side surface of the fixing plate. A spring is sleeved between the fixing plate and the inner wall of the storage groove, located outside the positioning rod.

[0008] Preferably, the side circumferential of the damper inspection cover is provided with a sealing ring, and the sealing ring is used in conjunction with the damper mounting groove.

[0009] Preferably, there are two storage slots, and the diameter of both storage slots is larger than the diameter of the pull ring.

[0010] Preferably, the diameter of the fixing plate is larger than the diameter of the spring, and the diameter of the spring is larger than the diameter of the positioning rod.

[0011] Preferably, the positioning rod is made of a hollow tube.

[0012] Preferably, the damper inspection cover plate fits into the damper mounting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, by setting a damper maintenance cover, the user can pull the ring to move it. The movement of the ring causes the fixing plate and positioning rod to move. After one end of the positioning rod moves out of the positioning hole, one end of the damper maintenance cover is lifted up. Then, the locking block is moved out of the locking groove. This allows for the maintenance and replacement of the damper components inside the damper mounting groove. Moreover, it can be operated without the need for professional technicians. It is easy to learn, highly practical, and worth promoting.

[0015] 2. By setting a sealing ring, the sealing effect can be improved, dust can be prevented from entering the interior of the damper mounting groove, and the impact and interference on the damping components inside the damping hinge can be reduced. The design is ingenious. Attached Figure Description

[0025] Please refer to Figure 1-4A door and window hinge designed to prevent the hinge from shifting when opened includes a damping hinge body 1. The damping hinge body 1 has a damper mounting groove 2, and the side wall of the damper mounting groove 2 has a slot 4. A locking block 5 is engaged inside the slot 4. A damper inspection cover 3 is detachably installed inside the damper mounting groove 2. One side surface of the locking block 5 is fixedly connected to the surface of the damper inspection cover 3. A positioning hole 7 is opened on one side surface of the damper inspection cover 3, and a positioning rod 8 is inserted into the positioning hole 7. A storage groove 11 is opened on one side surface of the damping hinge body 1, and a fixing plate 9 is installed inside the storage groove 11. A pull ring 10 is welded to one side surface of the fixing plate 9. One end of the positioning rod 8 extends into the storage groove 11 and is fixedly connected to the other side surface of the fixing plate 9. A spring 12 is sleeved between the fixing plate 9 and the inner wall of the storage groove 11, located outside the positioning rod 8.

[0026] In use, the damping hinge body 1 is installed on the corresponding door or window. The damper inspection cover 3 allows the user to pull the ring 10, which in turn moves the fixing plate 9 and the positioning rod 8. After one end of the positioning rod 8 moves out of the positioning hole 7, one end of the damper inspection cover 3 is lifted, and then the locking block 5 is removed from the slot 4. It should be noted that this structure is similar in principle to the battery cover on a child's toy, allowing for maintenance and replacement of the damper components inside the damper mounting slot 2. This can be done without the need for professional technicians, making it easy to learn and highly practical, and worthy of promotion. The sealing ring 6 improves the sealing effect, preventing dust from entering the damper mounting slot 2 and reducing the impact and interference on the damping components inside the damping hinge. The design is ingenious.

[0027] It should be noted that damping hinges themselves can prevent the fan from moving on its own. Through its internal damping mechanism, such as damping oil and friction plates, the damping hinge can generate resistance when the fan is opened, thereby slowing down the opening speed and preventing it from moving suddenly or moving on its own. This design allows the fan to gradually decelerate during the opening process, avoiding the impact and damage caused by sudden closing or opening. Damping hinges are widely used in occasions where movement speed needs to be controlled, such as furniture, automobiles, and aerospace. In furniture, damping hinges can be used for cabinet doors, drawers, etc., to make them close slowly, avoid pinching fingers, and reduce noise.

[0028] In this implementation scheme: a sealing ring 6 is provided on the side circumferentially of the damper inspection cover plate 3, and the sealing ring 6 is used in conjunction with the damper mounting groove 2.

[0029] Specifically, this reduces the risk of dust entering the damper mounting slot 2, minimizing the impact and interference on the internal damper components.

[0030] In this embodiment, there are two storage slots 11, and the diameter of both storage slots 11 is larger than the diameter of the pull ring 10.

[0031] Specifically, this ensures the stability of the damper inspection cover 3 and prevents it from becoming loose.

[0032] In this embodiment: the diameter of the fixing plate 9 is greater than the diameter of the spring 12, and the diameter of the spring 12 is greater than the diameter of the positioning rod 8.

[0033] Specifically, this allows the spring 12 to be positioned on the outside of the positioning rod 8, serving a resetting function.

[0034] In this implementation plan: the positioning rod 8 is made of hollow tube.

[0035] Specifically, while ensuring its own structural strength, it reduces its own weight and production costs.

[0036] In this implementation plan: the damper inspection cover 3 fits into the damper mounting groove 2.

[0037] Specifically, the sealing effect is more ideal, and dust is less likely to get in.

[0038] Working principle: In use, the damping hinge body 1 is installed on the corresponding door or window. The user can pull the ring 10 to move it via the damper access cover 3. The movement of the ring 10 moves the fixing plate 9 and the positioning rod 8. After one end of the positioning rod 8 moves out of the positioning hole 7, one end of the damper access cover 3 is lifted, and then the locking block 5 is removed from the slot 4. It should be noted that this structure is similar to the principle of a battery cover on a child's toy, allowing for maintenance and replacement of the damper components inside the damper mounting slot 2. No professional technicians are required to operate this system; it is easy to learn, highly practical, and worthy of promotion. The sealing ring 6 improves the sealing effect, preventing dust from entering the interior of the damper mounting slot 2 and reducing the impact and interference on the damping components inside the damping hinge. The design is ingenious.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
