Description

Technical Field

[0001] This invention relates to a rotary positioning device and its application method, particularly to a positioning device application method that allows for easy operation with automatic docking and locking and manual rotary unlocking. The device involves a limiting member assembled inside a base, fitted with a rotary seat. The two rotary guides of the limiting member and the two rotary sliding guides of the rotary seat rotate and slide relative to each other, rising and falling to engage or separate from the docking shaft, thereby facilitating the pressing, rotating, locking, or unlocking of the positioning device. Background Technology

[0002] Many everyday items utilize screws or pins as positioning mechanisms during their movement to achieve a positioning effect. For example, drawers and machine casings with telescopic structures use screws or pins to move slides or grooves to a predetermined position, temporarily positioning them so that users can work while the slides or grooves are in a fixed, stationary state. Similarly, devices assembled from multiple devices and mechanisms, such as desktop computers, laptops, industrial computers, and machine tools, use screws or pins to position panels when they are stacked, allowing the outer casing of the mechanism to have movable panels that can be assembled and disassembled, or allowing multiple devices or mechanisms to be easily assembled or disassembled relative to each other.

[0003] Furthermore, besides the risk of accidental injury from the sharp points and threads of ordinary screws and pins, which can cause injury to users, screws and pins often need to be completely removed when disassembling various devices, mechanisms, or plates. This frequently leads to the problem of lost screws and pins. If users do not have spare screws and pins and attempt to assemble using the remaining ones, the assembled mechanisms and plates will be unstable and prone to loosening or detachment. Also, after disassembling many screws and pins, it can be difficult to find the corresponding screw or pin for reassembly and fixation because they are all in the same location. Moreover, most screws and pins require hand tools (such as screwdrivers or wrenches) for disassembly and assembly. Depending on the type of screw or pin, users need to carry many hand tools, often resulting in difficulties in assembly and disassembly. These problems and deficiencies, constantly arising in practical use, make it extremely inconvenient to use screws and pins for layering and positioning of plates.

[0004] Furthermore, various interface cards or expansion cards in electronic devices are usually equipped with lever-type fasteners to secure them, allowing the electronic device to expand its functions. However, due to the current slots for various interface cards or expansion cards, it is necessary to first open the fasteners to lock or unlock them before inserting or removing them. However, due to space limitations in the electronic device where the slots for various interface cards or expansion cards are located, opening the fasteners becomes quite inconvenient. If the interface cards or expansion cards are not securely inserted, they may become unusable or inoperable. They may also be damaged due to collisions or friction with surrounding objects during insertion or removal. Therefore, there are still many shortcomings in practical applications.

[0005] Therefore, how to solve the inconvenience and troubles of conventional positioning devices in application and operation, as well as the troubles and deficiencies in assembly, positioning, etc., which are not conducive to plugging or unplugging, is the direction that relevant manufacturers in this industry are eager to research and improve. Summary of the Invention

[0006] Therefore, in view of the above-mentioned problems and deficiencies, the purpose of this invention is to provide a rotary positioning device and its application method.

[0007] The technical solution provided by this invention is as follows:

[0008] A method for applying a rotary positioning device, the rotary positioning device comprising a base, a limiting member, a rotary seat, an elastic member, and a docking shaft, the base comprising a seat body and a cover, wherein the seat body has an accommodating space and the cover has an assembly space, and the limiting member and the rotary seat are assembled and fitted opposite each other in the accommodating space and the assembly space, and the elastic member is fitted at the assembly space between the rotary seat and the cover, characterized in that, when performing locking or unlocking operations, the following steps are performed:

[0009] (A01) In the accommodating space inside the base body, the limiting member, the rotating seat and the elastic member are assembled in sequence. The rotating seat is rotated so that the two rotating slides at the bottom slide and move along the rotating guides on both sides of the limiting member. At the same time, the elastic member is rotated to twist. At this time, the accommodating groove inside the rotating seat is located outside the limiting ball on both sides of the limiting member.

[0010] (A02) The elastic element is placed outside the steering shaft of the rotating seat, and the second locking rod on one side of the elastic element passes through the second limiting hole on the rotating seat, and the first locking rod on the other side of the elastic element passes through the first limiting hole on the cover.

[0011] (A03) The cover is then used to cover the top of the seat body, and the sleeve provided in the assembly space inside the cover extends into the accommodating space, and the steering shaft of the rotating seat protrudes out of the sleeve. The cover can be rotated to align and snap onto the seat body at least one connecting part outside the accommodating space, forming a radial upward and downward displacement limiting effect. The seat body provides at least one stop limiting surface, which is aligned and abuts against the cover at least one limiting stop surface, forming an axial rotation limiting effect. The cover is then assembled and positioned on the seat body to maintain the elastic element under the torque generated by the rotation of the cover.

[0012] (A04) The base body is assembled to the pre-set plate using the bottom joint of the base body;

[0013] (A05) Assemble the docking part at the bottom of the docking shaft to another pre-set plate;

[0016] (A08) That is, the second guide slope of the stop body pushes the two limiting balls at the slots on both sides of the shaft hole, so that the two limiting balls are partially exposed outside each slot and abut against the wall of the elliptical accommodating groove provided in the rotating seat, so that the stop body passes over the two limiting balls and abuts against the top surface of the accommodating groove;

[0017] (A09) The stop body pushes the rotating seat to the assembly space and the steering shaft to the through hole, and at the same time, it rises axially and releases the torsional force on the elastic member, so that the positioning parts provided at the two adjacent positions of the two rotating guides of the limiting member at the two rotating slides are separated and the positioning is released.

[0018] (A10) The rotating seat is driven to rotate by the elastic reaction force of the elastic member, and the two rotating slides of the rotating seat and the two rotating guides of the limiting member slide axially to drive the receiving groove of the rotating seat to rotate and turn to the position of the two limiting balls located on the limiting member by the short axis diameter. At the same time, the wall surface of the short axis diameter pushes the two limiting balls to move into the slots on both sides respectively, and part of the two limiting balls enters the shaft hole and abuts against the first guide slope and shaft of the stop body.

Detailed Implementation

[0064] To achieve the above objectives and effects, the technical means, construction, and implementation methods adopted by the present invention are described in detail below with reference to the accompanying drawings, which will help to fully understand the features and functions of the preferred embodiments of the present invention.

[0065] Please see Figure 1 Figure 14As shown, the present invention provides a rotary positioning device and its application method. The rotary positioning device includes a base 1, a limiting member 2, a rotary seat 3, an elastic member 4, and a docking shaft 5, wherein:

[0066] The base 1 includes a base body 11 and a cover 12 disposed on the top of the base body 11. The base body 11 has a recessed accommodating space 110, and the bottom of the accommodating space 110 has a through hole 111 with a reduced diameter. The cover 12 is disposed on the other side of the accommodating space 110 opposite to the through hole 111. The cover 12 has an assembly space 120 disposed on the top of the base body 11. A sleeve 121 protrudes from the assembly space 120 and can extend into the accommodating space 110. The sleeve 121 has a through hole 1210 inside.

[0067] The limiting component 2 is assembled in the accommodating space 110 inside the base 11 and the cover 12. It has a through shaft hole 20 inside and two opposing rotating guides 21 outside. On the two sides of the shaft hole 20, there are radially through slots 22 extending to the outside. Each slot 22 has a limiting ball 23 inside.

[0068] The rotating seat 3 is assembled in the accommodating space 110 inside the seat body 11 and the cover 12, and is sleeved on the outside of the limiting member 2. The rotating seat 3 has an accommodating groove 30 inside and a steering shaft 31 with a reduced rod diameter outside that can be movably inserted into the through hole 1210 of the cover 12. At the bottom of the accommodating groove 30, two opposite sides are provided with rotating slides 32 that slide and rise along each rotating guide 21. Each rotating slide 32 and each rotating guide 21 are provided with a positioning part 33 at the adjacent position, which can be assembled and separated in a relatively movable locking manner.

[0069] The elastic element 4 is located between the outside of the sleeve 121, which is fitted inside the assembly space 120 of the cover 12, and the steering shaft 31 of the rotating seat 3.

[0070] The docking shaft 5 is movably inserted through the through hole 111 of the base 11 and then through the shaft hole 20 of the limiting member 2. A stop body 51 is provided on the top of the docking shaft 5, which can push the limiting balls 23 on both sides of the shaft hole 20 to move within the slots 22.

[0071] The base 1 of the present invention has a connecting portion 112 outside the through hole 111 of the base body 11, which can be connected to the first docking hole 60 of the preset first plate 6. Then, on the other side of the accommodating space 110, opposite to the through hole 111 and the connecting portion 112, there are at least one or more adjacent connecting portions 113 and at least one or more stop limiting surfaces 114. On the wall of the assembly space 120 of the cover 12, there are at least one or more adjacent inserting portions 122 and at least one or more limiting stop surfaces 123, which can be connected and assembled with at least one or more connecting portions 113 and at least one or more stop limiting surfaces 114 respectively. The base body 11 of the base 1 has at least one or more hook-shaped connecting portions 113 outside the accommodating space 110, and the wall of the assembly space 120 of the cover 12 has at least one or more hook-shaped inserting portions 122, which can be connected and snapped together with the connecting portions 113.

[0072] Furthermore, the base 1 of the present invention has a base body 11 with a fixing part 13 for holding and positioning at the bottom of the accommodating space 110 and the bottom surface of the limiting member 2. The fixing part 13 has at least one or more locking grooves 130 and at least one or more protruding locking bodies 131 that can be locked and fixed with at least one or more locking grooves 130 respectively at the bottom of the accommodating space 110 and the bottom surface of the limiting member 2, so that at least one or more locking grooves 130 and at least one or more protruding locking bodies 131 can be assembled and combined in a relatively interlocking manner.

[0073] Furthermore, the rotating seat 3 of the present invention has an elliptical receiving groove 30 inside. The minor axis diameter 301 of the elliptical receiving groove 30 is slightly larger than the rod diameter 2R of the limiting member 2, and the major axis diameter 302 of the receiving groove 30 is larger than the rod diameter 2R of the limiting member 2. This allows the elliptical receiving groove 30 of the rotating seat 3 to be located outside the limiting member 2 and rotate axially. When the minor axis diameter 301 of the receiving groove 30 aligns with the two limiting spheres 23 of the limiting member 2 (please also refer to...), Figure 12 (As shown), the two limiting balls 23 can be pushed into the two slots 22 and locked at the stop body 51 of the connecting shaft 5. Inner stop edges 221, slightly protruding from the shaft hole 20, are provided on the inner side of the two slots 22 to prevent the two limiting balls 23 from detaching from the two slots 22 and falling into the shaft hole 20. When the long axis diameter 302 of the receiving groove 30 is aligned with the two limiting balls 23 of the limiting member 2, the two limiting balls 23 can be displaced to partially protrude from the outside of the two slots 22 (please also refer to...). Figure 14 As shown), it abuts against the long axis diameter 302 of the receiving groove 30, and allows the stop body 51 of the docking shaft 5 to pass over the two limiting balls 23 and separate from the base 1 and the limiting member 2; in addition, a protruding rod body 35 is provided on the top surface of the receiving groove 30 of the rotating seat 3.

[0074] Furthermore, the cover 12 of the base 1 of the present invention has a first limiting hole 1201 on the top surface of the outer side of the sleeve 121 inside the assembly space 120, through which the first locking rod 41 provided on one side of the elastic member 4 can pass and be fixed. A second limiting hole 34 is provided on the outer side of the steering shaft 31 at the rotating seat 3, through which the second locking rod 42 provided on the other side of the elastic member 4 can pass and be fixed. The rotating seat 3 rotates within the assembly space 120 of the cover 12, driving the elastic member 4 to twist and form an elastic torque. Thus, the cover 12, the rotating seat 3, and the twisted elastic member 4 can be assembled and combined in the receiving space 110 of the base 11. Rotating the cover 12 allows for at least one... One or more interlocking parts 122 are aligned and snapped onto the seat body 11 at at least one connecting part 113 outside the accommodating space 110, forming a limiting effect for radial upward and downward displacement. At least one or more stop limiting surfaces 114 are aligned and abut against at least one or more limit stop surfaces 123, forming a limiting effect for axial rotation. The cover 12 is then assembled and positioned on the seat body 11 to maintain the elastic element 4 under the torque generated by the rotation of the cover 2, so that the elastic element 4 is stably sleeved between the sleeve 121 and the rotating seat 3. The elastic torque generated by the torsion of the elastic element 4 pulls the rotating seat 3 under the elastic torque and assembles it in the accommodating space 110 of the seat body 1.
