Description

Technical Field

[0001] This utility model relates to the field of hardware technology, and in particular to metal hardware with a linkage adjustment mechanism. Background Technology

[0002] Metal hardware components are indispensable connecting and supporting parts in products such as machinery, furniture, and doors and windows. Their main function is to achieve reliable fixing or relative movement between different components. In many application scenarios, hardware components that can bear loads and realize opening and closing actions are especially needed, such as various hinges and support arms.

[0003] Traditional load-bearing hardware typically has a relatively simple structural design. For example, a typical hinge structure often uses two plates connected by a single pivot or pin. In this structure, when the supported components such as the door panel or cover are in an open or load-bearing state, almost all the gravity, torque, and dynamic impact force generated by the movement are concentrated on this single pivot.

[0004] Over time, this highly concentrated stress causes rapid wear on the contact surfaces of the shaft and its mating holes, leading to gaps and loosening of the connection. This loosening not only causes annoying noises but, more seriously, reduces the stability of the entire structure, causing problems such as cabinet door sagging and inaccurate positioning. Ultimately, it significantly shortens the lifespan of the hardware itself and even the entire product. Therefore, this invention proposes a metal hardware component with a linkage adjustment mechanism to address the shortcomings of existing technologies. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides metal hardware with a linkage adjustment mechanism, which aims to improve the problem in the prior art where the load is concentrated on a single rotating shaft, which easily leads to loose connections.

[0006] This utility model provides a metal hardware component with a linkage adjustment mechanism, including: a fixing plate; a fixing post one, a fixing post two, and an anti-loosening screw two are fixed on the surface of the fixing plate; and a connecting rod one, a rotating shaft, a rotating plate, a fixing post three, a sliding plate, and a support component.

[0007] The core of the linkage adjustment mechanism lies in the combination of various components through unique and specific connection methods: the first connecting rod is rotatably connected to the first fixed column; the rotating shaft is fixed inside the first connecting rod; the rotating plate is rotatably connected to the rotating shaft and rotatably connected to the second fixed column; the third fixed column is fixed to the surface of the first connecting rod; the sliding plate is rotatably connected to the third fixed column and rotatably connected to the second anti-loosening screw, and at the same time, the sliding plate slides in the groove opened on the fixed plate; the support member is fixed to the surface of the sliding plate. Through this multi-point, multi-link linkage structure, the external load is effectively distributed.

[0008] Preferably, the metal hardware with linkage adjustment mechanism further includes a second spring washer; the second spring washer is fixed to the surface of the sliding plate and is arranged around the second anti-loosening screw to provide support for the rotation of the sliding plate around the second anti-loosening screw. While providing elastic buffer, it also increases the wear resistance and stability of the rotating part of the sliding plate.

[0009] Preferably, the surface of the sliding plate is also fixed with a positioning pin; the positioning pin is used to cooperate with the structure provided on the fixed plate when the sliding plate slides, so as to realize the adjustment positioning. By engaging or abutting with the positioning pin and the positioning hole or positioning groove preset on the fixed plate, the linkage mechanism can be easily locked at a specific opening angle or working position, thereby realizing the adjustment function.

[0010] Preferably, the metal hardware with linkage adjustment mechanism further includes a spring washer and an anti-loosening screw; the spring washer is fixedly connected to the surface of the fixing plate, and the anti-loosening screw is threadedly connected to the spring washer. This combination is used to firmly fasten components that are crucial to structural stability (such as the fixing column or the rotating plate connected to it) to the fixing plate to resist continuous vibration during operation and prevent loosening.

[0011] Preferably, to ensure the smoothness and stability of the overall movement of the linkage mechanism, the axial directions of the rotating shaft, the first fixed column, and the second fixed column are all parallel to each other. This parallel spatial layout ensures that the first connecting rod and the rotating plate can move stably in their respective rotation planes, avoiding interference or jamming during the linkage process.

[0012] Preferably, in order to accurately constrain the motion trajectory of the linkage mechanism, the axial direction of the fixed column three is parallel to the axial direction of the anti-loosening screw two, and is perpendicular to the sliding direction of the sliding plate. The orthogonal and parallel geometric relationship ensures that a definite motion coupling relationship is formed between the linear sliding of the sliding plate and the circular swing of the connecting rod one, thus ensuring the effective transmission of force and motion.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model solves the problem that the load of existing hardware is concentrated on a single rotating shaft, which easily leads to structural instability, rapid wear and poor durability. It achieves the technical effect of effectively distributing the load, thereby significantly improving the overall structural stability, load-bearing capacity and service life of the hardware.

[0015] 2. This utility model solves the problem of abnormal noise caused by loose screws in existing hardware under high-frequency vibration environment by setting auxiliary components such as spring washers and anti-loosening screws at the key connection positions of the sliding plate and the fixed plate. It achieves the technical effect of effectively offsetting vibration, preventing loosening of connection, and ensuring that the structure remains stable and reliable under high-frequency use.

[0016] 3. This utility model solves the problem that the movement range of some existing linkage mechanisms is fixed and cannot be adjusted as needed by setting positioning pins on the surface of the sliding plate. It achieves the technical effect of limiting the movement stroke of the linkage mechanism or locking it at a specific position, thereby realizing the adjustment function and enhancing the applicability of the device.

[0025] 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.

[0026] Example:

[0027] Reference Figures 1 to 3 This utility model provides a metal hardware component with a linkage adjustment mechanism, which aims to solve the problem that the load of the metal hardware component is concentrated at a single point, which easily leads to wear, loosening and structural instability in the prior art.

[0028] like Figure 1 As shown, the device includes a fixed plate 1, which serves as the mounting base for the entire device; the metal hardware with the linkage adjustment mechanism also includes a linkage mechanism 2, an auxiliary component 3, and a support component 4; the surface of the fixed plate 1 is fixed with a first fixed post 21, a second fixed post 25, and a second anti-loosening screw 35; the linkage mechanism 2 is used to realize complex linkage movements to distribute the load; the linkage mechanism 2 includes a first connecting rod 22, a rotating shaft 23, a rotating plate 24, a third fixed post 26, and a sliding plate 27; the first connecting rod 22 is rotatably connected to the first fixed post 21;

[0029] like Figure 2 and Figure 3 As shown, the rotating shaft 23 is fixed inside the connecting rod 22; the rotating plate 24 is rotatably connected to the rotating shaft 23 and rotatably connected to the fixed column 25; the fixed column 3 26 is fixed to the surface of the connecting rod 22; the sliding plate 27 is rotatably connected to the fixed column 3 26 and rotatably connected to the anti-loosening screw 35, and the sliding plate 27 slides in the groove opened on the fixed plate 1; the support member 4 is fixed to the surface of the sliding plate 27; the auxiliary component 3 includes a spring washer 31, an anti-loosening screw 32, a positioning pin 33, and a spring washer 34. The auxiliary component 3 cooperates with the connecting rod mechanism 2 to counteract vibration, prevent loosening, and assist in positioning.

[0030] Reference Figures 1 to 3The linkage mechanism 2 consists of a fixed column 21, a connecting rod 22, a rotating shaft 23, a rotating plate 24, a fixed column 25, a fixed column 3, and a sliding plate 27. One end of the connecting rod 22 is rotatably connected to the fixed column 21 fixed to the fixed plate 1, and the rotating shaft 23 is fixed inside the connecting rod 22. One end of the rotating plate 24 is rotatably connected to the rotating shaft 23, and the other end of the rotating plate 24 is rotatably connected to the fixed column 25 fixed to the fixed plate 1. The other end of the connecting rod 22 is rotatably connected to the sliding plate 27 via the fixed column 3 26 fixed to its surface. The sliding plate 27 is also rotatably connected to the fixed column 26. The anti-loosening screw 35 is fixed on the fixed plate 1, and the sliding plate 27 slides in the groove opened on the fixed plate 1. This structure allows the sliding plate 27 to perform a combined sliding and rotating motion when the support member 4 fixed on the sliding plate 27 is subjected to force. The motion is transmitted to the connecting rod 22 through the fixed column 26, which in turn drives the connecting rod 22 and the rotating plate 24 to move together. Finally, the load is distributed to the two fixed support points, the fixed column 21 and the fixed column 25, as well as the anti-loosening screw 35, which serves as the rotation support point. This effectively avoids stress concentration and improves the stability and durability of the structure.

[0031] Reference Figure 3 The device also includes a second spring washer 34; the second spring washer 34 is fixed to the surface of the sliding plate 27 and is arranged around the second anti-loosening screw 35 to provide support for the rotation of the sliding plate 27 around the second anti-loosening screw 35, while using its inherent elasticity to absorb the impact and vibration generated during the linkage process.

[0032] Reference Figure 1The sliding plate 27 is also fixed with a positioning pin 33. The positioning pin 33 is used to cooperate with the structure set on the fixed plate 1 when the sliding plate 27 slides to achieve adjustment and positioning, thereby allowing the user to limit the opening angle or working position of the linkage mechanism 2 as needed. It also includes a spring washer 31 and a locking screw 32. The spring washer 31 is fixedly connected to the surface of the fixed plate 1, and the locking screw 32 is threaded to the spring washer 31. This structure is used to securely install other components on the fixed plate 1. The axial direction of the rotating shaft 23, the axial direction of the fixed column 21, and the axial direction of the fixed column 25 are all parallel to each other. The parallel arrangement ensures that the linkage 22 and the rotating plate 2 are aligned. 4. It can rotate stably in a parallel plane. The axis of the fixed column 3 26 is parallel to the axis of the anti-loosening screw 2 35 and is perpendicular to the sliding direction of the sliding plate 27. The orthogonal and parallel relationship constrains the motion trajectory of the linkage mechanism 2, ensuring that it is linked in a preset manner. The spring washer 1 31, the anti-loosening screw 1 32, the positioning pin 33, the spring washer 2 34, and the anti-loosening screw 2 35 together constitute the auxiliary component 3 for fastening, anti-loosening, and positioning. At the same time, the fixed column 1 21, the connecting rod 1 22, the rotating shaft 23, the rotating plate 24, the fixed column 2 25, the fixed column 3 26, and the sliding plate 27 together constitute the linkage mechanism 2 that realizes the function of linkage and distributed load bearing.

[0033] The implementation principle of this application embodiment is as follows: when an external load acts on the support member 4, the load is transmitted to the sliding plate 27 through the support member 4, causing the sliding plate 27 to slide in the groove opened on the fixed plate 1. At the same time, the sliding plate 27 rotates around the anti-loosening screw 35 fixed to the fixed plate 1. The combined motion of the sliding plate 27 drives the connecting rod 22 to move through the fixed column 26 rotatably connected to it.

[0034] The movement of the connecting rod 22 is a rotation around the fixed column 21. Its rotation drives the rotating plate 24 to move through the fixed shaft 23. The rotating plate 24 rotates around the shaft 23 and the fixed column 25 at the same time. Through this series of linkage processes completed by the sliding plate 27, the connecting rod 22 and the rotating plate 24, the initial load applied to the support member 4 is effectively distributed to multiple support points such as the fixed column 21, the fixed column 25 and the anti-loosening screw 35 on the fixed plate 1. The structure avoids stress concentration, thereby significantly improving the structural stability, load-bearing capacity and durability of the entire metal hardware.

[0035] During this process, spring washer 31, anti-loosening screw 32 and spring washer 34 can absorb the vibration generated by the movement and prevent the threaded connection points from loosening, ensuring stability in high-frequency use environment; the positioning pin 33 set on the surface of the sliding plate 27 can cooperate with the structure set on the fixed plate 1 to limit the movement stroke of the sliding plate 27 or lock it in a specific position, realizing the function of adjusting the movement range of the linkage mechanism.
