Description

Technical Field

[0001] This utility model belongs to the field of fastener assembly technology, and in particular relates to an angle-adjustable metal fastener structure. Background Technology

[0002] Fasteners are a general term for mechanical parts used to fasten two or more parts together into a single unit. They are characterized by a wide variety of types and specifications, diverse performance and applications, and a high degree of standardization, serialization, and generalization. Adjustable-angle metal fasteners can be used to adapt to different installation angles and positions, compensate for manufacturing and installation errors, facilitate adjustment and maintenance, and improve the reliability and stability of connections. However, traditional adjustable-angle metal fasteners have limited adjustment precision, poor stability, complex structures, inconvenient installation, insufficient self-locking ability, and require improvement in corrosion resistance. To meet the requirements of modern adjustable-angle fasteners, new types of adjustable-angle metal fastener structures are used. In existing technologies, traditional adjustable-angle metal fasteners may not maintain a fixed angle after adjustment, and are prone to angle changes due to external forces, thus affecting the performance of the fastened components. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides an angle-adjustable metal fastener structure, which aims to solve the problem that traditional angle-adjustable metal fasteners may not be able to maintain a fixed angle after being adjusted to the required angle, and are prone to angle changes due to external forces, thereby affecting the performance of the fixed plate.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] An angle-adjustable metal fastener structure includes a base block, a limiting ring fixedly connected to the upper surface of the base block, a spring provided on the inner wall of the limiting ring, the lower end of the spring being disposed on the upper surface of the base block, a first limiting block fixedly connected to the upper end of the spring, a housing slidably connected to the outer wall of the first limiting block, a second limiting block slidably connected to the inner wall of the housing, the toothed end of the second limiting block engaging with the toothed end of the first limiting block, a push rod slidably connected to the inner wall of the second limiting block, and the outer wall of the push rod fixedly connected to the inner wall of the first limiting block.

[0006] As a preferred embodiment, the lower surface of the base block is provided with a bearing component, the bearing component including a connecting block one, the inner wall of the connecting block one being fixedly connected to the lower surface of the base block, and the inner wall of the connecting block one being slidably connected to the outer wall of the push rod.

[0007] As a preferred embodiment, the inner wall of the first connecting block is slidably connected to the second connecting block, and the inner wall of the second connecting block is slidably connected to the outer wall of the bottom block.

[0008] As a preferred embodiment, the inner wall of the second connecting block is fixedly connected to the outer wall of the outer shell.

[0009] As a preferred embodiment, a fastener body is fixedly connected to the outer left side of the connecting block 2, and the inner wall of the fastener body 1 is provided with a thread 1.

[0010] As a preferred embodiment, the right outer wall of the connecting block one is fixedly connected to the fastener body two, and the inner wall of the fastener body two is provided with thread two.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention uses a push rod to drive the first limiting block to move, causing the spring to deform. At the same time, the second limiting block separates from the first limiting block. Rotating the fastener body causes the second connecting block to rotate, which in turn causes the outer shell to rotate. Releasing the push rod allows the spring to rebound, thereby re-engaging the first limiting block with the second limiting block. This allows for adjustment of the fastener angle and self-locking without affecting the original performance of the plate. Attached Figure Description

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Please see Figures 1 to 4 As shown, this utility model embodiment provides an angle-adjustable metal fastener structure, specifically including a base block 1, a limiting ring 2 fixedly connected to the upper surface of the base block 1, a spring 3 provided on the inner wall of the limiting ring 2, the lower end of the spring 3 being provided on the upper surface of the base block 1, a limiting block 4 fixedly connected to the upper end of the spring 3, a housing 5 slidably connected to the outer wall of the limiting block 4, a limiting block 6 slidably connected to the inner wall of the housing 5, the toothed end of the limiting block 6 engaging with the toothed end of the limiting block 4, a push rod 7 slidably connected to the inner wall of the limiting block 6, the outer wall of the push rod 7 being fixedly connected to the inner wall of the limiting block 4, and a bearing component provided on the lower surface of the base block 1. The inner wall of connecting block 1 8 is fixedly connected to the lower surface of the bottom block 1, and the inner wall of connecting block 1 8 is slidably connected to the outer wall of the push rod 7; connecting block 2 9 is slidably connected to the inner wall of connecting block 1 8, the inner wall of connecting block 2 9 is slidably connected to the outer wall of the bottom block 1, and the inner wall of connecting block 2 9 is fixedly connected to the outer wall of the outer shell 5; fastener body 10 is fixedly connected to the left outer wall of connecting block 2 9, and the inner wall of fastener body 10 is provided with thread 12; fastener body 2 11 is fixedly connected to the right outer wall of connecting block 1 8, and the inner wall of fastener body 2 11 is provided with thread 2 13.

[0021] Specifically, in this embodiment, when the angle of the fastener needs to be adjusted, the push rod 7 is pressed down to separate the first limiting block 4 from the second limiting block 6. At the same time, the movement of the first limiting block 4 will cause the spring 3 to deform. The limiting ring 2 set on the outer wall of the spring 3 can limit the movement trajectory of the spring 3 to prevent displacement. The bottom block 1 can provide support for the whole. After pressing the push rod 7, the fastener body 2 11 or the fastener body 10 is rotated, thereby driving the connecting block 1 8 or the connecting block 2 9 to rotate. At the same time, the outer shell 5 will drive the second limiting block 6 to rotate. When it rotates to a certain angle, the push rod 7 is released to make the spring 3 rebound, thereby causing the first limiting block 4 and the second limiting block 2 6 to re-engage, thereby achieving a stable self-locking effect.

[0022] When this structure is needed, pressing down on push rod 7 pushes limit block 4 to slide against the inner wall of housing 5, causing spring 3 fixed to the upper surface of bottom block 1 to deform. The limit ring 2 restricts the movement trajectory of spring 3, and the movement of limit block 4 will separate from limit block 6. At this time, rotating fastener body 10 or fastener body 11 will cause connecting block 8 or connecting block 9 to rotate simultaneously. While rotating, housing 5 will drive limit block 6 to rotate, thereby adjusting the angle. When push rod 7 is released, the compressed spring 3 can push limit block 4 back to re-engage with limit block 6. This structure can achieve the effect of adjusting the angle of fastener while also achieving a self-locking effect.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
