Description

Rotary automatic positioning device

The present invention provides a rotary automatic positioning device, particularly a rotary automatic positioning device capable of rapid reset after rotation. The device comprises a base housing a shaft assembly. The shaft is provided with a spring element on both sides, positioned on the shaft and base, respectively. An assembly knob is exposed on one side of the shaft, allowing for reset after rotation, thereby facilitating the assembly and disassembly of the device.

Many items in daily life utilize positioning mechanisms such as screws or latches to achieve positioning when they move back and forth. For example, items with telescopic structures, such as drawers and case panels, utilize screws or latches to temporarily position the rails and chutes when they move to a predetermined position, allowing users to work while the rails and chutes are positioned and not moving. Alternatively, devices such as desktop computers, laptops, industrial computers, and workstations, which are assembled from multiple devices and mechanisms, utilize screws or latches to position the panels in a stacked state, allowing the outer casing of the mechanism to be provided with a panel that can be movably assembled and disassembled, or allowing multiple devices and mechanisms to be conveniently assembled or disassembled relative to each other.

Furthermore, in addition to the tips and threads of general screws and latches, which can cause injuries to users if they accidentally touch them, the entire screw or latch must be removed when disassembling various devices, mechanisms, or panels. This often leads to the problem of screws or latches being lost. If users do not have spare screws or latches, they will use the remaining screws or latches for assembly, resulting in an unstable assembly state of the assembled mechanism or panel, which is easy to loosen or fall off. It is also possible that after many screws or latches are removed, they will be placed on the screw or latch. The problem is that the corresponding screws or latches are placed in the same position and it is difficult to find the corresponding screws or latches for assembly and fixation. Furthermore, when installing or removing the screws or latches, most of them require the use of hand tools (such as screwdrivers or wrenches, etc.). As the types of screws or latches vary, users need to prepare many hand tools, which often leads to assembly and disassembly operations. Due to the above problems and defects in actual use, it is extremely inconvenient to use screws or latches for stacking and positioning of panels.

Usually, various interface cards or expansion cards in electronic devices are equipped with flip-type fasteners to fix the interface cards or expansion cards so that the electronic devices can expand various functions. However, in the current interface cards or expansion cards slots, when inserting or removing the interface cards or expansion cards, the fasteners must be flipped to lock or unlock them. However, this is affected by the electronic devices. The limited space in the slots for various interface cards or expansion cards makes it difficult to unlock the fasteners. Failure to securely insert the cards can easily lead to malfunctions and operational issues. These cards can also be damaged by collisions or friction with surrounding objects during insertion or removal, leading to numerous issues in actual use.

Therefore, how to solve the inconvenience and troubles of using fixed devices during application and operation, as well as the troubles and defects such as assembly and positioning that are not conducive to plugging or unplugging, is the direction that manufacturers in this industry are eager to research and improve.

Therefore, in view of the above-mentioned problems and deficiencies, the inventor collected relevant information, conducted multiple evaluations and considerations, and, drawing on years of experience accumulated in this industry, through continuous innovation, research, and improvement, finally designed and patented this rotary automatic positioning device.
