Detailed Implementation

[0054] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0055] In the description of this invention, the terms "inner", "outer", "longitudinal", "lateral", "upper", "lower", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and do not require that this invention must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0056] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0057] Example 1:

[0058] Embodiment 1 of the present invention provides an unlocking device for plugging and unplugging circuit boards, such as... Figure 1 and Figure 2 As shown, it includes: an unlocking rod 1, a locking block 2, and a locking seat 3. The unlocking rod 1 has a force-receiving part 11 at its rear end and a guide structure 12 at its front end. The locking block 2 has a locking hook 21 at its front end for locking the card. The locking block 2 has a rotating hole 22 in the middle and a guide groove 23 at its rear end. The guide structure 12 is slidably disposed in the guide groove 23. The force-receiving part 11 is used to receive external force to push the guide structure 12 to move in the guide groove 23, thereby driving the locking block 2 to rotate about the rotating hole 22 as an axis.

[0059] In order for the unlocking device to lock, a hook 21 is provided on the card block 2. The hook 21 is used to lock the card and the positioning hole on the chassis when the unlocking device is locked.

[0060] A rotating hole 22 is provided in the middle of the card block 2 to allow the card block 2 to rotate around the rotating hole 22 to achieve unlocking and locking. It should be noted that the aforementioned "middle" does not refer to the middle position of the card block 2, but is only used to illustrate that the rotating hole 22 is located between the hook 21 and the guide groove 23.

[0061] The guide groove 23 extends along its axis, and the axis of the guide groove 23 is inclined to the rotating hole 22.

[0062] To enable unlocking and locking, two guide slots 23 are also provided at the rear end of the card block 2, facing each other vertically, such as... Figure 3 As shown, the two guide grooves 23 are provided with two symmetrical notches 231. The guide structure 12 at the front end of the unlocking rod 1 is disposed in the notch 231. The guide structure 12 can slide back and forth within the notch 231. The guide structure 12 is defaulted to be located at the farthest end of the guide groove 23 (that is, the end away from the rotating hole 22, i.e.) Figure 3(The lower left end, which will not be described again below), at this time the unlocking device is in the locked state. When the guide structure 12 slides from the farthest end of the guide groove 23 to the nearest end of the guide groove 23 (referring to the end near the rotating hole 22, i.e.) Figure 3 When the upper right end (not described in detail below) is in the rotating hole 22, the hook 21 rotates, so that the hook 21 does not protrude from the bottom edge of the card holder 3, thereby unlocking.

[0063] In a preferred embodiment, such as Figure 4 The diagram shows the specific structure of the unlocking rod. The unlocking rod 1 also includes a cylinder 13. The force-receiving part 11 is located at the rear end of the cylinder 13. The front end of the cylinder 13 is also provided with two symmetrical smooth surfaces 14. The guide structure 12 is located at the front end of the smooth surface 14. The smooth surface 14 moves back and forth in the guide groove 23. The force-receiving part 11 includes a first block 111 and a second block 112. The second block 112 is located at the front end of the first block 111 and at the bottom of the cylinder 13. The first block 111 is used to receive external force.

[0064] Two symmetrical smooth surfaces 14 are cut out at the rear end of the cylinder 13. The smooth surfaces 14 are slidably disposed in the notch 231 of the guide groove 23. The guide structure 12 is disposed at the front end of the smooth surfaces 14. The area of ​​the first block 111 is larger than the area of ​​the second block 112. Therefore, the first block 111 is the main part that receives external force. When the first block 111 receives external force, the unlocking rod 1 drives the smooth surface 14 to move relative to the guide groove 23.

[0065] To enable the unlocking device to reset more conveniently and effortlessly, in a preferred embodiment, such as... Figure 5 As shown, the unlocking device also includes a spring 4, which is sleeved on the cylinder 13.

[0066] The spring 4 is mounted on the cylinder 13. One end of the spring 4 rests on the second block 112, and the other end of the spring 4 is located inside the card holder 3. When the first block 111 receives external force, the internal structure of the second block 112 and the card holder 3 will compress the spring 4, causing the spring 4 to contract. When the external force disappears, the spring 4 returns to its original state, thus completing the reset of the unlocking device.

[0067] The specific structure of the card holder 3 is described below, such as... Figure 6 The diagram shown is a schematic representation of the specific structure of the card holder 3. Figure 7The diagram shows a cross-sectional view of the unlocking rod 1 and the locking block 2 placed inside the locking seat 3. The locking seat 3 has a hollow structure and has a first section 31, a second section 32, and a third section 33. A square groove 34 is provided between the first section 31 and the second section 32. The second block 112 matches the square groove 34. The spring 4 is disposed between the second block 112 and the second section 32. The size of the first section 31 matches that of the first block 111. A cylindrical hole 35 is provided between the second section 32 and the third section 33. The smooth surface 14 at the front end of the unlocking rod 1 is disposed in the cylindrical hole 35.

[0068] like Figure 7 As shown, in the default state, the second block 112 is partially placed in the block slot, the size of the cylinder 13 matches the size of the cylindrical hole 35, and the smooth surface 14 is partially disposed in the cylindrical hole 35. When the first block 111 receives an external force, the second block 112 enters the block slot 34 until the first block 111 contacts the first cross section 31 and stops. The smooth surface 14 passes through the cylindrical hole 35, driving the guide structure 12 to move forward.

[0069] The second block 112 is matched with the block slot 34, meaning that the second block 112 can be perfectly accommodated in the block slot 34 and can slide back and forth in the block slot 34 without restriction. The first cross section 31 is matched with the size of the first block 111, meaning that the first block 111 can be perfectly attached to the first cross section 31, thereby limiting the movement distance of the second block 112.

[0070] In order for the guide structure 12 to slide in the guide groove 23, such as Figure 8 and Figure 9 The unlocking device shown also includes a first pin 5, and the card holder 3 is provided with a first round hole 36. The guide structure 12 is a fixing hole, the first pin 5 passes through the first round hole 36, and the first pin 5 is fixed in the fixing hole.

[0071] In this embodiment, the unlocking rod 1 needs to be placed on the card holder 3 before the first pin 5 is fixed in the fixing hole. The first round hole 36 is mainly for reserving a channel to facilitate assembly.

[0072] The first circular holes 36 are symmetrically arranged on the card holder 3. Since the guide structure 12 is slidably arranged in the guide groove 23, the notch 231 on the guide groove 23 also passes through the first circular holes 31. The first pin 5 is fixed in the fixing hole on the guide structure 12. The two ends of the first pin 5 do not protrude from the two sides of the two first circular holes 36, so that the guide structure 12 can move in the guide groove 23.

[0073] In other embodiments, the guide structure 12 can also be configured as a protruding post. Specifically, based on the unlocking rod 1 in the above embodiment, a protruding post can be directly set in the fixing hole and installed into the guide groove 23. The two ends of the protruding post need to be less than or equal to the width of the guide groove 23 but cannot exceed the first circular hole 36, so that the guide structure can slide in the guide groove 23. However, it should be noted that this type of guide structure is less conducive to assembly than the above-described guide structure 12, but the effect achieved is the same, and it is also a viable implementation method.

[0074] To facilitate the operation of the unlocking device, such as Figure 10 and Figure 11 As shown, the unlocking device provided in this embodiment also includes a handle 6 and a second pin 7. The front end of the handle 6 is provided with a second round hole 61, and the rear end of the card seat 3 is provided with a third round hole 37. The second pin 7 is rotatably disposed on the second round hole 61, and both ends of the second pin 7 are fixedly disposed in the third round hole 37.

[0075] The second pin 7 can be fixed in two ways so that the handle 6 can rotate around the third circular hole 37. The first way is to fix the second pin 7 in the second circular hole 61 and rotatably set both ends of the second pin 7 in the third circular hole 37. The second way is to fix both ends of the second pin 7 in the third circular hole 37 and rotatably set in the second circular hole 61. Both methods can realize the rotation of the handle 6 around the third circular hole 37.

[0076] The previous section introduced the structure related to the rotation of the handle 6. The following section introduces the structure on the handle 6 that applies force. The front end of the handle 6 is also provided with a convex surface 62, which is used to squeeze the force-receiving part 11 to push the unlocking rod 1.

[0077] The handle 6 has a flat surface and an arc surface on its convex surface 62 at the front end. In the default state, the flat surface contacts the first block 111. When the handle 6 is pulled, the handle 6 will rotate around the third circular hole 37 as an axis, and the arc surface will be tangent to the first block 111, thereby applying a squeezing force to the unlocking rod 1, pushing the unlocking rod 1 forward to achieve the unlocking function.

[0078] In other embodiments, handles with other structural forms can be selected, and corresponding bases can be provided.

[0079] To make the card block 2 rotate, as Figure 12 As shown, the tail of the card holder 3 is also provided with a card slot 38, and the card slot 38 is also provided with a fourth round hole 39. The fourth round hole 39 corresponds to the rotating hole 22. The rotating hole 22 is larger than the fourth round hole 39, and the external bolt passes through the fourth round hole 39.

[0080] The locking slot 38 is open on both sides, and the fourth circular hole 39 is fixed to the plate by an external bolt. Since the locking block 2 needs to rotate around the bolt, the rotating hole 22 should be set to be larger than the fourth circular hole 39 to ensure that the rotating hole 22 can rotate around the external bolt.

[0081] The above describes the specific structures included in the unlocking device. A schematic diagram of the overall structure of the unlocking device is shown below. Figure 13 As shown. Distinguished from the aforementioned. Figure 1 The embodiment shown is mainly different in that a handle 6 is added to facilitate the application of force. Other structures are described above and are not specifically limited here.

[0082] Example 2:

[0083] In Embodiment 1 above, an unlocking device for plug-in / plug-out boards was proposed. In this embodiment, a board structure is proposed to be used in conjunction with the unlocking device. The board has a receiving groove, the card holder 3 is fixedly disposed within the receiving groove, and the card block 2 is disposed within the receiving groove with the rotating hole 22 as its axis. The unlocking device proposed in Embodiment 1 is installed on the plug-in / plug-out board proposed in this embodiment, and its specific installation effect is as follows: Figure 14 and Figure 15 As shown.

[0084] The unlocking device is connected to the board through the fourth round hole 39 on the card holder 3 and fixed with bolts. The card block groove 38 on the card holder 3 is partially set in the receiving groove. After the unlocking device is fixedly set on the board, the card hook 21 on the card block 2 matches the positioning hole on the chassis to realize the connection between the board and the chassis.

[0085] More specifically, such as Figure 14 and Figure 15 As shown, after the unlocking device provided in Embodiment 1 is placed inside the plug-in card provided in this embodiment, the panel material of the plug-in card is clamped into the side gap of the card holder 3, thereby preventing the card holder 3 from rotating.

[0086] Then, align the fourth round hole 39 at the front end of the card holder 3 with the rotating hole 22 at the front end of the card block 2. The bolt passes through the bottom through hole of the plug-in card, and then through the fourth round hole 39 and the rotating hole 22 aligned at the front end of the card holder 3 and the card block 2. Place a washer and a nut at the upper plate hole on the inner side of the plug-in card, and install the unlocking device onto the plug-in card.

[0087] For details on the specific structure of the unlocking device, please refer to Embodiment 1, which will not be repeated here.

[0088] Example 3:

[0089] In Embodiments 1 and 2 described above, a pluggable board and an unlocking device for the pluggable board were provided. This embodiment will describe their specific usage.

[0090] The specific process of the usage method is as follows: Figure 16 As shown:

[0091] In step 101: when the unlocking device is in a self-locking state, the guide structure 12 of the unlocking rod 1 is at the farthest end of the guide groove 23.

[0092] When the unlocking device is locked, the spring 4 remains unchanged, the first pin 5 on the guide structure 12 is at the farthest end of the guide groove notch 231, the hook 21 on the card block 2 protrudes from the bottom surface of the card seat 3, and the hook 21 is engaged with the corresponding positioning hole on the chassis that is used with the unlocking device, thereby locking the card to the chassis.

[0093] Step 102: When unlocking is required, the force-receiving part 11 receives external force, pushes the guide structure 12 to move in the guide groove 23, and drives the guide structure 12 to move from the farthest end to the nearest end of the guide groove 23, so that the locking block 2 rotates about the rotating hole 22 as an axis.

[0094] When unlocking is required, simply pull the handle 6. The convex surface 62 at the front end of the handle 6 will press the unlocking rod 1. The unlocking rod 1 will drive the first pin 5 on the guide structure 12 to move forward. The first pin 5 moves from the farthest end of the guide groove 23 to the nearest end. The hook 21 on the card block 2 rotates upward and retracts into the bottom surface of the card seat 3, thereby unlocking the board from the chassis.

[0095] For details on the specific structure of the unlocking device and the plug-in card, please refer to Example 1, which will not be repeated here.

[0096] In conjunction with the unlocking device mentioned above, such as Figure 17 and Figure 18 As shown, when the unlocking device is in its natural state, i.e., in its self-locking state, the handle 6 and the card seat 3 are at a perpendicular angle, i.e., the handle 6 is parallel to the panel of the plug-in card. At this time, the flat part of the convex surface 62 on the handle 6 is flush with the end face of the first block 111, the spring 4 is in its natural state, and the first pin 5 pressed against the unlocking rod 1 is at the farthest end of the notch 231 of the card block 2. The hook 21 on the card block 2 extends out of the outer side of the card seat 3, i.e., the outer edge of the plug-in card.

[0097] like Figure 17 and Figure 18 As shown, the handle 6 of the unlocking device is parallel to the plug-in board, and the hook 21 on the card block 2 protrudes from the outer side of the plug-in board. When the plug-in board module is inserted into the chassis, the chassis will have corresponding guide rails and side openings. When the handle 6 is rotated at an angle, as shown... Figure 19 and Figure 20 As shown, the arc surface on the convex surface 62 of the handle 6 pushes the telescopic rod 1 forward, compressing the spring 4. The first pin 5 pressed onto the telescopic rod 1 slides from the farthest end of the guide groove notch 231 on the locking block 2 to the nearest end, thereby driving the locking block 2 to rotate around the rotating hole 22 as an axis. At this time, the hook 21 does not protrude from the outer side of the plug-in card. At this time, the plug-in card module can be inserted into the chassis guide rail. When the connector on the back of the plug-in card module matches the connector inside the chassis, the handle 6 is released. At this time, the plug-in card module returns to the self-locking state, i.e. Figure 17 and Figure 18 As shown, the spring 4 is partially stretched, the unlocking lever 1 moves backward, and the first pin 5 pressed on the unlocking lever 1 slides from the nearest end to the farthest end of the guide groove notch 231 of the locking block 2. The flat portion of the convex surface 62 of the handle 6 is flush with the outer surface of the first block 111. At this time, the hook 21 of the locking block 2 can enter the corresponding hole in the chassis, ensuring the locking state of the plug-in board module. When the plug-in board module is pulled out, rotating the handle 6 causes the locking block 2 to rotate and retract into the plug-in board, allowing it to be pulled out smoothly.

[0098] In all the above embodiments, according to the unlocking device provided in Embodiment 1, the plug-in card proposed in Embodiment 2 for use with the unlocking device, and the method of using the unlocking device provided in Embodiment 3, the unlocking device is applied to the plug-in card. By pulling the handle, the tail of the unlocking rod is squeezed, and the unlocking rod drives the guide structure to move back and forth in the guide groove of the card block, thereby controlling the locking and unlocking of the card block hook. This allows for the rapid installation and disassembly of the card, improving production efficiency and optimizing the production process.

[0099] Example 4:

[0100] The foregoing embodiments mainly introduce a pluggable board, an unlocking device applied to the pluggable board, and its usage method. More specifically, based on the actual scenario, an appropriate number of unlocking devices can be selected and applied to the pluggable board. Also, according to the actual situation, a suitable handle can be selected to ensure that the connection and insertion of panel devices are not affected.

[0101] Scenario 1: The handle is parallel to the board. In this case, an unlocking device can be set on one or both sides of the board.

[0102] The unlocking device can be located on one side of the module board. For example... Figure 21 As shown, the handle 6 of the unlocking device is parallel to the board, and the convex surface of the hook 21 protrudes from the outer side of the board. At this time, the board is locked to the chassis.

[0103] The unlocking device can be installed on both sides of the module board, suitable for situations where the module span is large and the connector insertion and extraction force is high. For example... Figure 22 As shown, the unlocking device can also be set on both sides of the board. This setting is suitable for situations where the module span is large and the connector insertion and extraction force is large.

[0104] Scenario 2: The handle is perpendicular to the board. In this case, an unlocking device can be installed on one or both sides of the board.

[0105] The unlocking device can be located on one side of the module board. For example... Figure 23 As shown, the handle 6 of the unlocking device can be positioned on another vertical surface of the card holder 3, which can avoid affecting the connection of other devices on the panel. The convex surface of the hook 21 protrudes from the outer side of the card, and the card is locked to the chassis at this time.

[0106] The unlocking device can be installed on both sides of the module board, suitable for situations where the module span is large and the connector insertion and extraction force is high. For example... Figure 24 As shown, the unlocking device can also be set on both sides of the board. This setting is suitable for situations where the module span is large and the connector insertion and extraction force is large.

[0107] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
