Abstract
Description
Technical Field
[0001] This application relates to the field of computer technology, and more particularly to electronic device locking devices and electronic devices. Background Technology
[0002] In the current architecture of electronic devices, there are various functional and structurally different boards and modules. The installation method is mainly screw fastening, which not only requires relevant tools, but also requires sufficient installation space, thus hindering the efficiency of assembly and maintenance, and limiting the online deployment of various server configurations. Summary of the Invention
[0003] This application provides an electronic device locking device and an electronic device to at least solve the problem of low efficiency in disassembling and assembling electronic device modules in related technologies.
[0004] This application provides an electronic device locking device, including: a fixing member and a rotating assembly. The fixing member has a central through hole for connecting to an electronic device module. The inner wall of the central through hole has a plurality of circumferentially spaced and axially extending locking wall ribs. Adjacent locking wall ribs form axially extending rib grooves. The end of each locking wall rib has a first guide slope that extends continuously in the circumferential direction. The rotating assembly is rotatably and axially movable in the central through hole. The rotating assembly has a limiting part for limiting engagement with a mounting hole of the chassis, and a mating part for engaging with the rib groove. When the rotating assembly moves axially, the mating part extends out of the rib groove and abuts against the first guide slope. The mating part can rotate circumferentially under the inclination of the first guide slope, and drive the limiting part to rotate circumferentially to be aligned with or misaligned with the mounting hole.
[0005] This application also provides an electronic device, including an electronic device module, a chassis, and the aforementioned electronic device locking device. The chassis has mounting holes; the electronic device locking device is connected to the electronic device module and can be matched with the chassis for positioning.
[0006] By means of this application, the rotating component is axially movable within the central through hole, and the rotating component has a mating part that engages with the locking rib on the inner wall of the central through hole. This allows the rotating component to rotate circumferentially, and consequently, the limiting part located at the end of the rotating component can move axially and rotate circumferentially. This allows the limiting part to move to the side wall of the mounting hole and be limited by the mounting hole, or to move to the side wall away from the mounting hole. Thus, the entire locking process does not require any tools. The circumferential alignment or misalignment of the limiting part with the mounting hole of the chassis can be achieved solely through the axial movement and rotation of the rotating component. This enables rapid disassembly and assembly between the electronic device module and the chassis, thereby solving the problems of assembly space limitations, low production efficiency, and high maintenance costs caused by the tools required during the disassembly and assembly of electronic device modules in the prior art. When the rotating component moves axially, the mating part extends out of the rib groove and abuts against the first guide slope at the end of the locking wall rib of the fixing part. Under the inclination of the first guide slope, the limiting part rotates circumferentially. This action process simplifies the locking and unlocking operation, improves the assembly efficiency in a limited space, reduces maintenance costs, and ensures the rapid disassembly and assembly and stability of electronic equipment. Therefore, it can solve the technical problem of low disassembly and assembly efficiency of electronic equipment modules in related technologies, and achieve the technical effect of improving the disassembly and assembly efficiency between electronic equipment modules and the chassis.

[0019] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0020] The embodiments of this application provide an electronic device locking device and an electronic device. The device is described in detail below in conjunction with its structure and working principle.
[0021] like Figures 1 to 7An electronic device locking device is shown, including a fixing member 10 and a rotating assembly 20. The fixing member 10 has a central through hole 11 for connecting to an electronic device module. The inner wall of the central through hole 11 has a plurality of circumferentially spaced and axially extending locking wall ribs 12. A rib groove 13 extending axially is formed between adjacent locking wall ribs 12. The end of each locking wall rib 12 has a first guide slope 121 extending continuously in the circumferential direction. The rotating assembly 20 is rotatably and axially movable in the central through hole 11. The rotating assembly 20 has a limiting part for limiting and engaging with the mounting hole of the chassis, and a engaging part 2121 for engaging with the rib groove 13. When the rotating assembly 20 moves axially, the engaging part 2121 extends out of the rib groove 13 and abuts against the first guide slope 121. The engaging part 2121 can rotate circumferentially under the inclination of the first guide slope 121, and drive the limiting part to rotate circumferentially to be aligned with or misaligned with the mounting hole.
[0022] This embodiment sets the rotating component 20 to be axially movable within the central through hole 11, and the rotating component 20 has a mating part 2121 that engages with the locking rib 12 on the inner wall of the central through hole 11. This allows the rotating component 20 to rotate circumferentially, and consequently, the limiting part located at the end of the rotating component 20 can move axially and rotate circumferentially. This allows the limiting part to move to the side wall of the mounting hole and be limited by the mounting hole, or to move to the side wall away from the mounting hole. In this way, the entire locking process does not require any tools. The circumferential alignment or misalignment of the limiting part with the mounting hole of the chassis can be achieved solely through the axial movement and rotation of the rotating component 20. This enables rapid disassembly and assembly of the electronic device module and the chassis, thereby solving the problems of assembly space limitations, low production efficiency, and high maintenance costs caused by the tools required during the disassembly and assembly of electronic device modules in the prior art. When the rotating component 20 moves axially, the mating part 2121 extends out of the rib groove 13 and abuts against the first guide slope 121 at the end of the locking wall rib 12 of the fixing member 10. Under the inclination of the first guide slope 121, the limiting part rotates circumferentially. This action process can simplify the locking and unlocking operation, improve the assembly efficiency in a limited space, reduce maintenance costs, and at the same time ensure the quick disassembly and assembly and stability of electronic equipment.
[0023] It should be noted that the central through hole 11 in this embodiment is a circular hole, meaning that the fixing member 10 is hollow. The axial direction mentioned in this embodiment refers to the axial direction along the central through hole 11, that is... Figure 1 The direction from the lower left to the upper right in the text refers to the circumferential direction along the central through hole 11. In this embodiment, the electronic device module can refer to components such as circuit boards, hard drive modules, and fan modules.
[0024] In this embodiment, the locking wall rib 12 is rib-shaped, and a first guide slope 121 is provided at one end of the locking wall rib 12 near the mating part 2121. The first guide slope 121 is set as a plane and is inclined along the axial direction of the central through hole 11. That is to say, the axial position of the first guide slope 121 is different along different positions in the circumference of the central through hole 11. In this way, the first guide slope 121 can provide a guiding effect for the rotation of the mating part 2121. When the mating part 2121 abuts against the first guide slope 121, the mating part 2121 can move axially and rotate along the inclined direction of the first guide slope 121, thereby realizing the synchronous axial movement and circumferential rotation of the rotating component 20.
[0025] In this embodiment, the rotating assembly 20 includes a rotating member 21 and a limiting member 22. The rotating member 21 has a mating portion 2121, which is rib-shaped. The limiting member 22 is connected to the rotating member 21 and has a limiting portion. When the electronic device locking device is locked in the mounting hole, the limiting member 22 and the mating portion 2121 are located on both sides of the mounting hole, thereby forming an effective limiting on both sides of the mounting hole and ensuring a reliable connection between the electronic device module and the chassis. Specifically, as shown... Figure 3 As shown, in this embodiment, the rotating member 21 is configured as a connecting rod, and the mating part 2121 is disposed on the outer periphery of the rotating member 21 and is elongated. The length direction of the mating part 2121 extends axially and faces the direction of the rib groove 13. The limiting member 22 is disposed at the end of the rotating member 21 and is located at the end of the rotating assembly 20 away from the rib groove 13. When the rotating member 21 drives the limiting member 22 to rotate until the limiting part is circumferentially aligned with the side wall of the mounting hole, the electronic device module and the chassis are locked. When the rotating member 21 drives the limiting member 22 to rotate until the limiting part is circumferentially misaligned with the side wall of the mounting hole, the electronic device module and the chassis are unlocked. It should be noted that when the limiting part is circumferentially aligned with the mounting hole, it means that when the limiting part and the rotating part 21 are located on opposite sides of the mounting hole, the limiting part rotates to outside the columnar area where the mounting hole is located and aligns with the side wall of the mounting hole along the axial direction of the central through hole 11, thereby achieving the contact between the limiting part and the side wall of the mounting hole, i.e., the chassis, thus locking the electronic device module and the chassis. When the limiting part is circumferentially misaligned with the mounting hole, it means that the limiting part rotates to inside the columnar area where the mounting hole is located, thereby causing the limiting part and the side wall of the mounting hole to be misaligned axially. In this way, when the limiting part moves axially, it will not be blocked by the side wall of the mounting hole, thus unlocking the electronic device module and the chassis.
[0026] In this embodiment, the rotating assembly 20 further includes a fastener 23. The rotating component 21 has a threaded hole, and the limiting component 22 has a through hole 221. The fastener 23 passes through the through hole 221 and is threadedly engaged with the rotating component 21 to fix the limiting component 22, thereby ensuring a reliable connection and detachability between the limiting component 22 and the rotating component 21. Specifically, the fastener 23 can be a screw with its head located on the side of the limiting component 22 away from the rotating component 21. After passing through the through hole 221, the screw is threadedly connected to the end of the rotating component 21. Thus, when adjusting the circumferential position of the limiting component 22 according to actual needs, the screw can be loosened, the limiting component 22 can be rotated, and after the limiting component 22 is adjusted to a suitable position, the screw can be tightened again, thereby improving the flexibility and adaptability of the electronic device locking device in this embodiment. In this embodiment, a recess is also provided on the periphery of the through hole 221. The recess is located on the side of the limiting member 22 near the rotating member 21. When the limiting member 22 is fixed to the end of the rotating member 21, the end of the rotating member 21 is embedded in the recess, thereby further improving the reliability of the connection between the limiting member 22 and the rotating member 21. The other positions of the limiting member 22 near the rotating member 21, excluding the recess, can be set as a plane and serve as the limiting part, that is, the contact surface when the limiting member 22 abuts against the chassis.
[0027] In this embodiment, the limiting member 22 has an adjacent first side 222 and a second side 223. The distance between the first side 222 and the through hole 221 is greater than the distance between the second side 223 and the through hole 221. When the electronic device locking device is locked into the mounting hole, the first side 222 acts as a limiting part and cooperates with the chassis for limiting. Thus, by utilizing the different cooperation relationship between the limiting member 22 and the chassis after rotation, the unlocking and locking of the electronic device module and the chassis can be realized.
[0028] Specifically, the limiting member 22 is configured as a non-circular structure. In this embodiment, the through hole 221 is located at the center of the limiting member 22, ensuring that the center of the limiting part is aligned with the central axis of the rotating member 21. When the first side 222 rotates to the side wall of the mounting hole, and the side wall of the mounting hole prevents the limiting member 22 from moving axially towards the rotating member 21, the electronic device module and the chassis are locked. When the first side 222 rotates to the area where the mounting hole is located, and the side wall of the mounting hole can no longer prevent the limiting member 22 from moving axially towards the rotating member 21, the limiting member 22 can move to the same side as the rotating member 21 located in the mounting hole, and the electronic device module and the chassis are unlocked. Figure 2As shown, in this embodiment, the limiting member 22 is set as a rectangular block with a rectangular cross-section. The first side 222 is the side where the short side of the rectangle is located, and the second side 223 is the side where the long side of the rectangle is located. The mounting hole on the chassis is correspondingly set as a hole with a rectangular or oblong cross-section. When the first side 222 rotates to the long side of the mounting hole, since the distance between the long side of the mounting hole and the axis of the mounting hole is small, the first side 222 can abut against the side wall of the mounting hole, thereby locking the electronic device module and the chassis. When the first side 222 rotates to the short side of the mounting hole, since the distance between the short side of the mounting hole and the axis of the mounting hole is large, the first side 222 is located in the cylindrical space where the mounting hole is located and cannot abut against the side wall of the mounting hole, thereby allowing the limiting member 22 to move axially within the mounting hole, thereby unlocking the electronic device module and the chassis. The contact between the limiting member 22 and the side wall of the mounting hole does not refer to contact within the mounting hole, but rather to axial contact with the side wall of the mounting hole, i.e., contact between the limiting part and the chassis. It should be noted that the cross-section refers to the section perpendicular to the axial direction. Of course, depending on the actual situation, the limiting member 22 can also be configured with other structures. For example, the limiting member 22 can be configured as a cross-shaped block, giving it four protruding arms extending from the center outwards. These protruding arms serve as limiting parts. Correspondingly, the mounting hole should be configured to fit the shape of the limiting member 22, such as a cross-shaped hole similar to the limiting part, with similar four protruding areas. After the rotating member 21 drives the limiting member 22 to rotate at a certain angle, the limiting part can contact the side wall between the protruding areas, thereby locking the electronic device module and the chassis. When the limiting part rotates into the protruding area, the limiting member 22 can move axially within the mounting hole, thereby unlocking the electronic device module and the chassis.
[0029] like Figure 3As shown, in this embodiment, the end of the mating part 2121, that is, the end of the mating part 2121 away from the limiting member 22, has a second guide slope 2122 that extends continuously in the circumferential direction. The inclination direction of the second guide slope 2122 is the same as the inclination direction of the first guide slope 121. This allows the mating part 2121 to rotate along the inclination direction of the first guide slope 121 and rotate into another adjacent rib groove 13 after it disengages from the rib groove 13 and abuts against the first guide slope 121. This allows the mating part 2121 to rotate simultaneously along the axial movement and rotation of the rotating member 21. In this way, when the first guide slope 121 and the second guide slope 2122 work together, they ensure surface contact, thereby improving the guiding effect of the first guide slope 121, ensuring the stability of the rotating member 21 during rotation, and realizing smooth unlocking and locking of the electronic device locking device. Optionally, the inclination angle of the second guide slope 2122 can be set to 45°, that is, the second guide slope 2122 forms a 45° angle with the cross section of the rotating member 21.
[0030] In this embodiment, there are multiple mating parts 2121, and each mating part 2121 corresponds to a rib groove 13. This ensures that along the circumference of the central through hole 11, the multiple mating parts 2121 and rib grooves 13 provide stable and reliable mating. Furthermore, it ensures uniform circumferential force during the rotation of the rotating component 21, improving the stability of the rotation and facilitating a smooth transition between unlocking and locking states. Specifically, along the circumference of the rotating assembly 20, the mating parts 2121 are spaced apart, the inclination directions of the first guide slopes 121 are consistent, and the inclination directions of the second guide slopes 2122 are also consistent. Figure 3 , Figure 4 As shown, in this embodiment, there are four mating parts 2121 and four rib grooves 13. This allows the mating part 2121 to rotate along the inclined direction of the first guide slope 121 to another adjacent rib groove 13 after it disengages from one rib groove 13. This causes the rotating member 21 to rotate 90 degrees each time it rotates, thereby driving the limiting member 22 to rotate 90 degrees. In this way, the limiting part of the limiting member 22 can rotate from being misaligned with the mounting hole to being aligned with the mounting hole, so that the limiting member 22 can abut against the side wall of the mounting hole to achieve locking.
[0031] In this embodiment, the electronic device locking device further includes an operating member 30. At least a portion of the operating member 30 is axially movably disposed within the central through hole 11. A rotating member 21 is movably disposed within the operating member 30. When the mating part 2121 disengages from the rib groove 13, the operating member 30 drives the rotating member 21 to rotate, thereby enabling the electronic device locking device to switch between unlocked and locked states simply by pressing the operating part axially. Specifically, as... Figure 1 , Figure 5 As shown, in this embodiment, both the operating member 30 and the rotating member 21 are inserted into the central through hole 11. The operating member 30 is cylindrical, with its outer periphery engaging with the fixing member 10, and engaging with the rotating member 21 within the central through hole 11. The operating member 30 is hollow and is used to engage with the end of the rotating member 21. When the operating member 30 is pressed, it moves axially towards the limiting member 22, thereby driving the rotating member 21 to move axially through contact with it. The axial movement of the rotating member 21 causes the engaging part 2121 to disengage from the rib groove 13. Continuing to press the operating member 30, the rotating member 21 is freed from the circumferential limiting effect of the rib strip. The pressing member drives the rotating member 21 to rotate circumferentially until it abuts against the second guide slope 2122 and the first guide slope 121. Under the guidance of the first guide slope 121, the first guide slope 121 continues to rotate to the first guide slope 121. The electronic module is circumferentially limited by the adjacent rib groove 13 within the inclined surface 121. When the operating member 30 is released, the mating part 2121 can extend axially into the rib groove 13. At this time, if the limiting member 22 abuts against the chassis, the electronic module is locked to the chassis. If the limiting member 22 is rotated to a position away from the side wall of the mounting hole, the electronic module is unlocked to the chassis. The entire switching process can be achieved by simply pressing the operating member 30, without the need for other tools and is simple and easy to operate, thereby improving the assembly efficiency and convenience of the internal components of the electronic device.
[0032] In this embodiment, the operating member 30 has a plurality of circumferentially arranged tips 311. On opposite sides of the tips 311 are provided third guide slopes 3111 and fourth guide slopes 3112 with opposite inclination directions. The tips 311 abut against the mating part 2121 and can drive the mating part 2121 to move axially and circumferentially, thereby ensuring that during operation, the mating part 2121 can move precisely along a predetermined axial and circumferential path, thus improving the accuracy and efficiency of the operation. Specifically, the operating member 30 has a plurality of tips 311 near the end of the mating part 2121, and the plurality of tips 311 are arranged circumferentially along the central through hole 11, thereby forming a zigzag edge structure along the circumference of the operating member 30. Along the axis of the central through hole 11, the second guide slope 2122 has a high point and a low point. The high point and the low point are located at two opposite edges of the second guide slope 2122. The high point is the edge of the second guide slope 2122 away from the limiting member 22, and the low point is the edge of the second guide slope 2122 close to the limiting member 22. That is, the high point and the low point are arranged along the axial direction and along the circumferential direction. When the mating part 2121 is located in the rib groove 13, and the operating member 30 is pressed so that the tip 311 abuts against the second guide slope 2122, the tip 311 does not abut against the high point or low point of the second guide slope 2122, but rather abuts against the middle position between the high point and the low point of the second guide slope 2122. This allows the second guide slope 2122 to disengage from the rib groove 13 under the abutment of the tip 311, while the tip 311 can still move relative to the second guide slope 2122 under the action of external force. That is, the tip 311 slides along the second guide slope 2122. When the second guide slope 2122 reaches its lowest point, the operating member 30 is pressed and its circumferential position relative to the fixing member 10 is fixed. Therefore, the second guide slope 2122 moves, causing the mating part 2121 to move axially away from the limiting member 22 and circumferentially towards the first guide slope 121. This rotation continues until the first guide slope 121 and the second guide slope 2122 come into contact. After the contacting action of the operating member 30 is lost, the second guide slope 2122 can continue to rotate into the adjacent rib groove 13 under the tilting action of the first guide slope 121. Of course, this embodiment is not limited to the specific structure shown in the figure. The number and shape of the tips 311, as well as the tilt angles of the third guide slope 3111 and the fourth guide slope 3112, can be adjusted and optimized according to specific application requirements to achieve optimal operating performance.
[0033] like Figure 5As shown, in this embodiment, the operating member 30 has a plurality of circumferentially arranged sliding protrusions 312. The sliding protrusions 312 are located within the rib groove 13 and can slide axially along the extending direction of the rib groove 13, thereby preventing circumferential rotation when the operating member 30 moves axially. Specifically, the sliding protrusions 312 are located on the outer periphery of the operating member 30, and the sliding protrusions 312 are also configured as ribs, extending axially along the central through hole 11. The sliding protrusions 312 and the tip 311 are axially arranged, and the sliding protrusions 312 are located on the side of the tip 311 away from the limiting member 22. Considering that before pressing the operating member 30, both the sliding protrusion 312 and the mating part 2121 are located within the rib groove 13, the maximum axial distance between the sliding protrusion 312 and the tip 311 is set to be less than the axial length of the rib groove 13. This ensures that when the sliding protrusion 312 is located within the rib groove 13, the mating part 2121 and the sliding protrusion 312 are axially arranged and also located within the rib groove 13. Thus, when the operating member 30 is pressed, the sliding protrusion 312 moves axially within the rib groove 13, and the tip 311 abuts against the midpoint between the high and low points of the second guide slope 2122, thereby driving the axial movement of the rotating member 21. This, in turn, causes the mating part 2121 to disengage from the rib groove 13 and rotate, thereby achieving effective control of the rotating member 21. To match the number of rib grooves 13 and mating parts 2121, in this embodiment, four sliding protrusions 312 and four tips 311 are arranged circumferentially and evenly distributed.
[0034] In this embodiment, the operating member 30 also includes a rod 31 and a first nut 32. The rod 31 is axially movable in the central through hole 11. The first nut 32 is located at the end of the rod 31 and has a first abutting surface 321 for abutting against the fixing member 10. In this way, the rod 31 can be axially displaced in the central through hole 11. The first nut 32 can limit the axial movement distance of the rod 31 by abutting against the end of the fixing member 10, thereby achieving precise control of the rotating member 21. Specifically, in this embodiment, the rod 31 is configured as a hollow structure, with a sliding protrusion 312 on the outer periphery of the rod 31. The end of the rod 31 near the rotating member 21 is provided with a tip 311, and the end of the rod 31 away from the rotating member 21 is provided with an external thread, which is threaded to the first nut 32. This allows the operating member 30 to move a certain distance axially towards the rotating member 21, after which the first abutting surface 321 abuts against the end of the fixing member 10 away from the limiting member 22, thereby limiting the movement distance of the rod 31 and preventing the sliding protrusion 312 from coming out of the rib groove 13. This ensures the stability of the axial movement of the operating member 30, prevents the failure of the fit between the operating member 30 and the rib groove 13, and improves the reliability of the electronic device locking device.
[0035] In this embodiment, the electronic device locking device further includes an elastic element 40, which is sleeved on the outside of the rotating member 21 and provides the rotating member 21 with a spring force close to the operating member 30. This allows the mating part 2121 to automatically rotate and slide along the first guide slope 121 into another adjacent rib groove 13 after disengaging from the rib groove 13. Specifically, in this embodiment, the elastic element 40 is located at the end of the rotating member 21 away from the operating member 30. The elastic element 40 may be provided with a spring, and the deformation direction of the spring is along the axis of the central through hole 11, so that the spring can provide the mating part 2121 with a spring force close to the operating member 30 along the axial direction. When the pressing operation member 30 disengages the mating part 2121 from the rib groove 13, the mating part 2121 is simultaneously subjected to the axial elastic force of the elastic member 40 and the axial abutment force of the tip 311, with the two forces in opposite directions. The position of the mating part 2121 remains unchanged. After the operation member 30 is released, the abutment force of the tip 311 on the mating part 2121 disappears, and the mating part 2121 is subjected to the elastic force of the elastic member 40. Under the inclination of the second guide slope 2122, the mating part 2121 rotates circumferentially until it abuts against the second guide slope 2122 and the first guide slope 121. It then rotates circumferentially along the first guide slope 121 and moves axially towards the operation member 30, ultimately moving the mating part 2121 into the adjacent rib groove 13. In this way, when no external force is applied to the operation member 30, the rotating member 21 can automatically return to the preset position, maintaining the stable state of the electronic device locking device. In addition, the presence of the elastic element 40 makes the pressing operation smoother. The user only needs to press the operating element 30 to trigger the rotation of the rotating element 21, thereby realizing the locking or unlocking action.
[0036] In this embodiment, the rotating member 21 includes a first segment 211, a second segment 212, a third segment 213, and a fourth segment 214 arranged sequentially along the axial direction. The first segment 211 passes through the operating member 30. The second segment 212 has a mating part 2121 and can abut against the operating member 30. The elastic member 40 is sleeved on the outside of the third segment 213. The fourth segment 214 is connected to the limiting member 22, so that the axial and circumferential force can be transmitted simply by pressing the operating member 30, thereby realizing the automatic unlocking and locking of the electronic device locking device. The overall outer diameter of the rotating member 21 is stepped. The diameter of the second segment 212 is larger than the diameter of the third segment 213. A stop surface 215 for limiting the elastic member 40 is formed between the third segment 213 and the second segment 212.
[0037] Specifically, such as Figure 3As shown, the rotating component 21 is generally configured as a cylindrical rod, with the diameters of the first segment 211 and the second segment 212 increasing sequentially, and the diameters of the second segment 212, the third segment 213, and the fourth segment 214 decreasing sequentially. The hollow structure of the rod body 31 of the operating component 30 has openings at both ends. The first segment 211 enters the rod body 31 from the end with the pointed end 311 and is limited by the end of the rod body 31 away from the limiting member 22, preventing the first segment 211 from exiting the rod body 31. Optionally, the end of the rod body 31 away from the limiting member 22 can be configured as a bottle cap-like structure with an observation hole in the center, allowing the first segment 211 to be seen from the end of the rod body 31 away from the limiting member 22, while preventing the first segment 211 from exiting through the observation hole, thus confining the first segment 211 inside the rod body 31.
[0038] The second segment 212 has a mating part 2121 at one end near the first segment 211. The radial thickness of the mating part 2121 is greater than the radial thickness of the sliding protrusion 312 and also greater than the radial thickness of the tip 311. This allows the second guide slope 2122 to both abut against the tip 311 axially and be axially positioned within the rib groove 13 with the sliding protrusion 312. A stop surface 215 perpendicular to the axial direction of the rotating member 21 is formed at the connection between the second segment 212 and the third segment 213 to prevent the elastic member 40 from dislodging from the third segment 213 under pressure. When the rotating component 21 is inserted inside the fixing component 10, the second segment 212, the third segment 213, and the elastic component 40 are all located inside the central through hole 11. The first segment 211 can extend out of the central through hole 11 away from the limiting component 22 synchronously with the operating component 30 under the elastic force of the elastic component 40. When the operating component 30 is pressed, the fourth segment 214 can extend out of the central through hole 11 near the limiting component 22. In this way, the rotating component 21 can ensure effective cooperation with the operating component 30 and the fixing component 10, while ensuring the correct position of the elastic component 40 during use.
[0039] In this embodiment, the fourth segment 214 has a circumferential stop notch 2141. The limiting member 22 is connected to the fourth segment 214, and at least a portion of the limiting member 22 is located within the stop notch 2141, thereby ensuring the stability of the connection between the limiting member 22 and the rotating member 21 and preventing the limiting member 22 from being subjected to circumferential external forces and causing relative movement with the rotating member 21, resulting in locking failure. Specifically, the end of the fourth segment 214 away from the third segment 213 is connected to the limiting member 22, and the stop notch 2141 is provided at the end of the fourth segment 214. In this embodiment, two stop notches 2141 are provided, and the two stop notches 2141 are symmetrically arranged on both sides of the axis of the rotating member 21, respectively used to limit the two first sides 222. In this embodiment, both sides of the recess of the limiting member 22 are first sides 222. When the end of the fourth segment 214 is embedded in the recess and connected and fixed with the limiting member 22, the first side 222 near the edge of the recess can be embedded into the stop notch 2141, thereby limiting the circumferential position of the limiting member 22.
[0040] In this embodiment, the end of the first segment 211 furthest from the second segment 212 has a first marking portion 2111, and the operating member 30 has a second marking portion 313. When the first marking portion 2111 and the second marking portion 313 are aligned, the electronic device locking device is locked in the mounting hole. This allows the operator to identify the locking status of the electronic device locking device by observing the positions of the first marking portion 2111 and the second marking portion 313, thereby improving the convenience of operation and avoiding misoperation. In this embodiment, the first marking portion 2111 is set to pass through the central axis of the first segment 211, with the engraved line extending radially. The second marking portion 313 is set as two dots, with the line connecting the two dots passing through the central axis of the rod 31. This allows the operating member 30 to rotate in two ways: the engraved line and the dots are aligned, or the engraved line and the dots are misaligned, making it easier for the operator to identify the locking status. Both the engraved line and the dots can be set using a screen printing process.
[0041] In this embodiment, the electronic device locking device further includes a second nut 50, which is threadedly connected to the end of the fixing member 10 away from the first nut 32, and limits the rotating member 21 and the elastic member 40 within the central through hole 11. The second nut 50 has a second abutment surface 51 for abutting against the elastic member 40. The second nut 50 may include an axially connected first segment and a second segment. The first segment is closer to the elastic member 40 than the second segment. The first segment is provided with an external thread, and the end of the fixing member 10 near the second nut 50 is provided with an internal thread, so that the first segment can be tightened inside the fixing member 10. The surface of the first segment away from the second segment can serve as the second abutment surface 51 for abutting against the elastic member 40, thereby limiting the elastic member 40 within the central through hole 11 and preventing the rotating member 21 from coming out of the end of the fixing member 10 near the limiting member 22. The outer periphery of the second segment may be provided with an anti-slip groove 52 to facilitate operator operation, thereby increasing friction and facilitating operator operation. The surface of the second segment away from the first segment can serve as a third contact surface that abuts against the limiting member 22, thereby limiting the limiting member 22 to the outside of the fixing member 10, so as to prevent the limiting member 22 from entering the central through hole 11 of the fixing member 10 from the hole inside the second nut 50.
[0042] like Figure 4 As shown, in this embodiment, the fastener 10 has connecting holes 14 for connecting to an electronic device module, ensuring a reliable connection between the electronic device locking device and the electronic device module. Specifically, this embodiment has two connecting holes 14, which are diagonally distributed at both ends of the diagonal of the fastener hole to ensure the reliability of the connection between the fastener 10 and the electronic device module. Countersunk screws, rivets, etc., can be inserted into the connecting holes 14 to connect to the electronic device module, ensuring connection strength while facilitating disassembly and assembly, improving the flexibility of the electronic device locking device, and promoting its reuse. Of course, the number and position of the connecting holes 14 can be adjusted according to actual conditions, as long as a reliable connection between the fastener 10 and the electronic device module is ensured.
[0043] In this embodiment, the fixing member 10 has multiple positioning protrusions 15 arranged axially. The positioning protrusions 15 can be rectangular blocks located on the outer periphery of the fixing member 10, and the positioning protrusions 15 and the connecting holes 14 are located on the same side of the fixing member 10. The electronic device module can be provided with positioning grooves that mate with the positioning protrusions 15. When installing the fixing member 10 onto the electronic device module, the positioning protrusions 15 are first installed into the positioning grooves to achieve positioning between the electronic device module and the fixing member 10. Then, the fixing member 10 is fixed to the electronic device module through the connecting holes 14. Thus, the positioning protrusions 15 are used for initial positioning and support with the electronic device module, and the connecting holes 14 are used to achieve a reliable connection with the electronic device module. Figure 6As shown, this embodiment has four positioning protrusions 15, which are arranged axially in pairs to achieve reliable positioning between the fixing member 10 and the electronic device module. Of course, the shape, number and arrangement of the positioning protrusions 15 can be adjusted according to the actual situation to ensure reliable positioning between the fixing member 10 and the electronic device module.
[0044] This embodiment of the electronic device locking device breaks with conventional thinking. Within a limited space, without any tools, assembly and disassembly can be achieved with a single pressing action. This not only maximizes the use of the available space in the electronic device, enabling tool-free assembly and disassembly of internal modules such as circuit boards, but also improves production efficiency and reduces maintenance costs. Furthermore, the entire device features a centrally symmetrical design, a simple structure, an attractive appearance, and easy operation. Assembly is also very simple: just insert the operating component 30, rotating component 21, and elastic component 40 into the central through hole 11 of the fixing component 10, tighten the second nut 50, position the limiting component 22 and lock it with the fastener 23, and finally tighten the first nut 32. In use, the fixing component 10 is installed onto the electronic device module using riveting or screw fastening, enabling the electronic device locking device to unlock and lock the electronic device module and chassis. To improve the accuracy of the electronic device locking device, the machining tolerance of each component can be controlled within 0.1mm.
[0045] Taking an electronic device locking device placed vertically with the operating member 30 at the top and the limiting member 22 at the bottom as an example, the operation process of the electronic device locking device in this embodiment is as follows: Pressing the first nut 32 causes the operating member 30 to extend downward and rotate 90°, thereby unlocking or locking. The rotating member 21 and the marking member on the top of the operating member 30 facilitate identification of the locking state. Specifically, initially, the electronic device locking device is in the unlocked state, i.e. Figure 6In the current state, the elastic element 40 is compressed, and the second guide slope 2122 acts on the tip 311, causing the end of the sliding protrusion 312 away from the limiting element 22 to abut against the end of the rib groove 13 away from the limiting element 22. At the same time, the limiting part contacts the surface of the second nut 50 away from the elastic element 40, and the limiting element 22 is located directly above the mounting hole of the chassis. When locking, pressing the operating member 30 compresses the elastic element 40 until the lower surface of the first nut 32, that is, the first abutting surface 321, abuts against the upper end surface of the fixing member 10. The limiting element 22 passes through the mounting hole. At this time, the tip 311 pushes the second guide slope 2122 out of the rib groove 13. Under the upward elastic force of the elastic element 40, the second guide slope 2122 moves along the third guide slope 3111 towards the second guide slope. The bottom of 2122 moves, causing the rotating part 21 to rotate. At the same time, the elastic part 40 is released, and the second guide slope 2122 moves to contact the first guide slope 121. After the operating part 30 is released, the second guide slope 2122 continues to rotate along the first guide slope 121 under the pushing force of the elastic part 40 until the second guide slope 2122 and the first guide slope 121 are completely misaligned. At this time, the rotating part 21 drives the limiting part 22 to rotate 90°, and the mating part 2121 falls into the rib groove 13 and continues to move upward until the limiting part 22 hooks onto the side wall of the mounting hole. The top end face of the rotating part 21 is flush with the top end face of the operating part 30, and the first marking part 2111 is aligned with the second marking part 313. This completes the locking process. The unlocking process is the same as the locking process, and will not be described again.
[0046] This embodiment also provides an electronic device, including an electronic device module, a chassis, and the aforementioned electronic device locking device. The chassis has mounting holes; the electronic device locking device is connected to the electronic device module and can engage with the chassis for limiting. Thus, locking and unlocking between the chassis and the electronic device module can be achieved by unlocking and locking the electronic device locking device, which can be achieved simply by pressing the operating part 30, without requiring any other additional tools. This greatly facilitates the adjustment and maintenance of the internal structure of the electronic device, reduces tool dependence, saves operating space, improves assembly efficiency, and also reduces maintenance costs.
[0047] In this embodiment, the mounting hole has an adjacent first sidewall and a second sidewall. The first sidewall is farther away from the center of the mounting hole than the second sidewall, so that the cross-section of the mounting hole is not a regular circular hole. When the electronic device locking device is locked into the mounting hole, the limiting part is close to the second sidewall, thereby ensuring reliable contact between the limiting part and the sidewall of the mounting hole. In this embodiment, the contact between the limiting part and the side wall of the mounting hole refers to the contact along the axial direction. When the limiting part contacts the second side wall, the second side wall prevents the limiting part from moving axially toward the operating member 30 with the rotating member 21, thereby restricting the limiting member 22 and the fixing member 10 to both sides of the mounting hole along the axial direction, thereby locking the electronic device module and the chassis. When the operating member 30 is pressed, the limiting member 22 rotates until the limiting part is radially aligned with the first side wall. However, since the first side wall is far from the center of the mounting hole, the limiting part cannot make axial contact with the first side wall, thereby allowing the limiting part to move axially within the mounting hole. This allows the limiting member 22 to move toward the operating member 30 with the rotating member 21, thereby moving the limiting member 22 to the same side of the mounting hole as the rotating member 21, thereby unlocking the electronic device module and the chassis.
