Description

Technical Field

[0001] The utility model relates to a hinge, in particular to a hardware hinge with an anti-loosening function. Background Art

[0002] As an important accessory for connecting components such as doors and cabinets, the hardware hinge is widely used in fields such as furniture, doors and windows, and mechanical equipment. Its main function is to achieve relative movement between components, such as opening and closing, rotation, etc. Traditional hardware hinges usually consist of parts such as hinge cups, hinge arms, and connecting rods, and the opening and closing of the hinge are realized through a hinge mechanism. However, with the increase in the use time, traditional hinges often have problems with insufficient anti-loosening performance in actual applications, specifically manifested as:

[0003] 1. High risk of loosening: During the long-term use of traditional hardware hinges, due to frequent opening and closing operations or external vibrations, the screws at the hinge connection parts are prone to loosening or the connection structure is prone to loosening, thereby affecting the stability and service life of the hinge.

[0004] 2. Poor installation firmness: When installing the connection structure of existing hinges, it often relies on screw fixation or simple snap connection methods, lacking effective anti-loosening designs. This not only increases the complexity of installation but also reduces the firmness of the connection, resulting in the hinge being prone to displacement or falling off during use.

[0005] 3. Frequent maintenance: Due to the insufficient anti-loosening performance of traditional hinges, users need to frequently check and tighten the screws during use, increasing the maintenance cost and operation complexity, and affecting the user experience.

[0006] 4. Material and process limitations: Existing anti-loosening designs mostly rely on additional materials or complex processing techniques, such as adding anti-slip teeth, locking devices, etc. This not only increases the production cost but may also affect the overall aesthetics and structural strength of the hinge.

[0007] 5. Limited scope of application: The anti-loosening design of traditional hinges often targets specific application scenarios and lacks universality, making it difficult to meet the diverse market demands. For example, in occasions with high-frequency use or heavy loads, existing hinges are prone to problems with insufficient anti-loosening, restricting their scope of application. Therefore, it is necessary to make further changes to it. Summary of the Utility Model

[0023] The following further specifically describes the present utility model with reference to the accompanying drawings. A hardware hinge with an anti-loosening function includes a hinge cup 1 and a hinge arm 2. The hinge cup 1 and the hinge arm 2 are hinged through an upper connecting rod 3 and a lower connecting rod. The upper connecting rod 3 and the lower connecting rod swing relative to the hinge cup 1 and the hinge arm 2 to realize the opening and closing of the hinge. The hinge arm 2 is connected to the cabinet body through a base 4. The base 4 includes a connecting plate 41 and a connecting seat 42 protruding from its top. An installation groove is provided at the bottom of the hinge arm 2, and the connecting seat 42 is snapped into the installation groove to be connected to the hinge arm 2;

[0024] A plurality of installation holes 43 are provided on the connecting seat 42. A counterbore area 44 extends from the installation holes 43 towards the bottom of the connecting plate 41. A plurality of anti-slip teeth 45 extend downward from the bottom of the counterbore area 44. When the connecting seat 42 is installed with the cabinet body board, the anti-slip teeth 45 are inserted into the cabinet body board to increase the friction between the connecting seat 42 and the cabinet body board.

[0025] In one embodiment: the anti-slip teeth 45 are bosses provided at the bottom of the counterbore area 44, and the height of the bosses is 0.5 mm to 1.5 mm.

[0026] In one embodiment: the anti-slip teeth 45 are burrs formed by turning the material at the bottom of the counterbore area 44 downward.

[0027] In one embodiment: the anti-slip teeth 45 are sawteeth formed by tearing the material of the counterbore area 44 downward.

[0028] In one embodiment: the anti-slip teeth 45 are embossed teeth provided on the back of the counterbore area 44.

[0029] In one embodiment: the counterbore area 44 and the anti-slip teeth 45 and the connecting seat 42 are integrally formed by stamping a metal plate.

[0030] Working principle: In this case, the bottom of the hinge arm 2 is connected to the cabinet body through the base 4. The base 4 includes a connecting plate 41 and a connecting seat 42 protruding from its top. An installation groove is provided at the bottom of the hinge arm 2, and the connecting seat 42 is snapped into the installation groove to be firmly connected to the hinge arm 2, ensuring the stable connection between the hinge arm and the hinge cup.

[0031] Among them, a number of mounting holes 43 are provided on the connecting seat 42. A counterbore area 44 extends from each mounting hole 43 towards the bottom of the connecting plate 41. A number of anti-slip teeth 45 extend downward from the bottom of the counterbore area 44. During the installation of the hinge, the anti-slip teeth 45 are inserted into the cabinet body board material. Through the physical embedding method, the friction between the connecting seat 42 and the cabinet body board material is significantly increased. This design effectively prevents the hinge from loosening due to vibration or frequent opening and closing operations during long-term use.

[0032] In addition, the anti-slip teeth 45 of the present utility model can adopt various forms, such as bosses provided at the bottom of the counterbore area 44, burrs formed by turning down the material at the bottom of the counterbore area 44, sawteeth formed by tearing down the material of the counterbore area 44, and embossed teeth provided on the back of the counterbore area 44. These different forms of anti-slip teeth enhance the anti-loosening effect of the hinge by increasing the locking points and friction, adapt to cabinet body board materials of different thicknesses and materials, and improve the adaptability and stability of the hinge in various application environments.

[0033] Among them, the counterbore area 44 and the anti-slip teeth 45 and the connecting seat 42 are integrally formed by stamping a metal plate. This manufacturing process simplifies the production process, reduces the manufacturing cost, and at the same time improves the overall structural strength between the connecting seat and the anti-slip teeth. Through integral forming, the risk of loosening that may be brought by the connection of multiple components is avoided, further enhancing the durability and reliability of the hinge.

[0034] Among them, the anti-slip teeth 45 are designed simply and integrally formed with the connecting seat 42, without adding additional structural components and without affecting the appearance beauty of the hinge. At the same time, the diversified design of the anti-slip teeth enables the hinge to still maintain a good visual effect in different application scenarios, meeting the user's requirements for the beauty of the hardware accessories. Due to the anti-slip teeth 45 having a variety of form options, the hardware hinge of the present utility model can adapt to cabinet body board materials of different thicknesses and materials, is widely applicable to various fields such as furniture, doors and windows, and mechanical equipment, and especially provides a more reliable connection in occasions with high-frequency use or large load-bearing, expanding the application range of the hinge.

[0035] Compared with the traditional technology, in this case, the anti-slip teeth 45 significantly increase the friction between the connecting seat 42 and the cabinet body board material by being embedded in the cabinet body board material, effectively preventing the hinge from loosening due to vibration or frequent operations during long-term use, improving the overall stability and safety of the hinge, so it can be widely promoted and used.
