Detailed Implementation

[0055] 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.

[0056] 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.

[0057] 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.

[0058] Example 1:

[0059] In this embodiment, an unlocking device for a movable disk is provided, see reference. Figure 1 and Figure 2The unlocking device includes: a fixed plate 1, a sliding block 2, and a locking body 3. The locking body 3 includes a sliding post 31. The fixed plate 1 includes a base plate 10 with a first circular hole 101 and a first notch 102 at one end. A first chamfer 11 is provided at the front end of the fixed plate 1. A first groove 21 is provided at the front end of the sliding block 2 with a first guide structure 211. The sliding post 31 is slidably disposed in the first groove 21 and has a first inclined surface 311 and a second inclined surface 312. The first inclined surface 311 and the second inclined surface 312 have a stepped structure. One end of the fixed plate 1 is fixed inside the chassis. The first chamfer 11 is used to press the second inclined surface 312, and the first guide structure 211 is used to press the first inclined surface 311.

[0060] A first groove 21 is provided at the front end of the sliding block 2, and a first guide structure 211 is provided on the first groove 21. The sliding post 31 is slidably disposed in the first groove 21, and the locking body can slide up and down in the first groove 21.

[0061] The upper inclined surface of the first guide structure 211 slopes downwards, meaning it slopes downwards along the connection point with the first groove 21 towards the center of the first groove 21. Thus, with... Figure 2 Taking the perspective as an example, when the slider 2 is pulled to the right, the first guide structure 211 makes it easier to push the slider 31 upward.

[0062] The sliding column 31 has a first inclined surface 311 and a second inclined surface 312. The first inclined surface 311 and the second inclined surface 312 have a stepped structure, that is, the lower bottom part of the first inclined surface 311 and the upper top part of the second inclined surface 312 are located in the same cross-sectional circle.

[0063] One end of the fixed plate 1 is fixed inside the chassis. When the movable plate is pushed close to the chassis, as... Figure 3 As shown, the first chamfer 11 presses against the second inclined surface 312, thereby applying an upward force to the sliding column 31, causing the sliding column 31 to move upward and its bottom to disengage from the movable plate, as... Figure 4 As shown, the left and right pictures are cross-sectional views of the sliding column 31 before and after it is squeezed. Continue to push the movable disc until the sliding column 31 enters the first circular hole 101 of the fixed plate 1 to achieve locking. In the locked state.

[0064] like Figure 5As shown, the locking body 3 is engaged in the first circular hole 101 and the first groove 21. Since the bottom of the fixing post 32 of the locking body 3 is fixed to the movable plate (described in detail below), the connection between the chassis and the movable plate is achieved and the two are locked together. Figure 6 The image shown is a cross-sectional view of the locking body 3 after it has been locked.

[0065] When unlocking is required, such as Figure 7 As shown, by moving the sliding block 2 backward, the first guide structure 211 on the sliding block 2 will exert an upward force on the first inclined surface 311 on the sliding post 31, thereby giving the sliding post 31 an upward force and causing it to move upward until the bottom of the sliding post 31 is higher than the base plate 10 on the fixed plate 1. Figure 8 As shown, the sliding column 31 moves upward and its bottom disengages from the movable plate. At this time, if the sliding block 2 is pulled further, the bottom part of the sliding column 31 will disengage from the first circular hole 101 on the fixed plate 1 and pull the movable plate out of the chassis slot as a whole, thereby unlocking.

[0066] In this embodiment, as Figure 9 The diagram shown is a detailed structural schematic of the sliding column 31, where, as... Figure 9 As shown in b, a first cylinder 313 is provided between the first inclined surface 311 and the second inclined surface 312, and a second cylinder 314 is provided below the second inclined surface 312. A first stepped circular hole 315 is provided at the center of the sliding cylinder 31. Two symmetrical second notches 3151 are additionally opened on the upper side of the first stepped circular hole 315. A third notch 316 is further opened between the second inclined surface 312 and the second cylinder 314, and the opening direction of the third notch 316 is parallel to the opening direction of the second notch 3151. Wherein, as... Figure 9 As shown in Figure a, the sliding post 31 has a hollow structure. From top to bottom, the sliding post 31 has a first stepped circular hole 315, a second stepped circular hole 317, and a third stepped circular hole 318, with their opening radii decreasing sequentially. Figure 9 As shown in Figure c, the diameter L3 of the second cylinder 314 is smaller than the diameter L4 of the first cylinder 313.

[0067] like Figure 10 The diagram shows the structure of the fixed post 32. The locking body 3 also includes the fixed post 32. The fixed post 32 includes a third cylinder 321. The bottom of the third cylinder 321 is provided with a first protrusion 322. The first protrusion 322 is provided with a positioning pin 323. The size of the first protrusion 322 matches the size of the third notch 316 of the sliding post 31.

[0068] The fixing post 32 is a hollow structure. The first protrusion 322 extends outward from the side wall at the bottom of the fixing post 32. A positioning pin 323 is provided vertically downward at the tail end of the first protrusion 322. The bottom of the third cylinder 321 is provided with a first threaded hole 324, the top of the third cylinder 321 is provided with a second threaded hole 325, and the top of the third cylinder 321 is also provided with a second groove 326. The positioning pin 323 is placed in the positioning hole on the movable plate. The first threaded hole 324 matches the countersunk hole on the movable plate, thereby fixing the fixing post 32 on the movable plate. The first protrusion 322 of the fixing post 32 matches the size of the third notch 316 of the sliding post 31, so that the sliding post 31 can be fitted onto the fixing post 32.

[0069] In order to enable the sliding column to automatically return to its original position, in a preferred embodiment, the locking body 3 further includes a locking spring 33 and a mounting block 34. The locking spring 33 is disposed in the first stepped circular hole 315 of the sliding column 31 and sleeved on the fixed column 32. The locking mounting block 34 is installed in the first stepped circular hole 315.

[0070] The specific structure of the locking spring 33 and the mounting block 34 is as follows: Figure 11 As shown, two protrusions 341 are symmetrically provided at the bottom of the mounting block 34, such as... Figure 12 The diagram shows the structure of the locking body 3. When assembling the locking body, the protrusion 341 is placed in the second notch 3151 on the sliding post 31, and its upper end is connected to the fixed post 32 with a screw, thereby locking the locking spring 34 in the sliding post 31. At the same time, the shape and size of the protrusion 341 also match the second groove 326 on the fixed post 32, so that the protrusion 341 can be placed in the second groove 326.

[0071] The locking spring 33 is disposed in the first stepped circular hole 315 of the sliding post 31 and sleeved on the fixed post 32. When assembling the locking body 3, the fixed post 32 is first fixed on the movable plate as described above. Then, the third notch 316 and the first protrusion 322 are aligned, the sliding post 31 is sleeved on the fixed post 32, and the locking spring 33 is sleeved on the fixed post 32 through the first stepped circular hole 315. The boss 341 at the bottom of the mounting block 34 is aligned with the second notch 3151 and placed on the upper part of the locking body 3, and fixed with screws. Thus, the locking body 3 is assembled.

[0072] In actual use, the sliding column 31 receives external force and compresses the locking spring 33 during its upward movement. After the external force applied to the sliding column 31 is released, the locking spring 33 restores its deformation and pushes the sliding column 31 back to its original position.

[0073] The specific structure of fixing plate 1 is described below, such as... Figure 13 The diagram shows the specific structure of the fixing plate 1. The fixing plate 1 also includes a first folded edge 12 and a second folded edge 13. The first folded edge 12 and the second folded edge 13 are disposed on both sides of the substrate 10. A first countersunk hole 121 is provided on the substrate 10 and the first folded edge 12 for fixing the fixing plate 1 in the chassis. A second circular hole 131 is provided on the second folded edge 13. The second circular hole 131 is concentric with the first circular hole 101. The opening diameter of the second circular hole 131 is larger than that of the first circular hole 101. A fourth notch 132 is provided at one end of the second circular hole 131. A third groove 103 is provided at the other end of the first circular hole 101. A fifth notch 104 is provided at the outer end of the first notch 102. The fourth notch 132 and the fifth notch 104 have the same size. A second guide structure 14 is also provided at the front end of the fixing plate 1.

[0074] The first folded edge 12 and the second folded edge 13 are respectively disposed on both sides of the substrate 10. Two rivets are selected and driven into the two first countersunk holes 121 respectively, so that the first folded edge 12 on the fixing plate 1 is fixed inside the chassis. Figure 13 As shown in Figure b, the second circular hole 131 and the first circular hole 101 are located at the same center, and the opening diameter D2 of the second circular hole 131 is larger than the opening diameter D1 of the first circular hole 101. In addition, a fourth notch 132 is opened at one end of the second circular hole 131. The opening size of the first notch 102 is L1, and the opening size of the fourth notch 132 is L2, and L1 is smaller than L2. The second guide structure 14 is used to make the fixing plate 1 more smooth when pressing the locking body 3, and less prone to jamming.

[0075] like Figure 14 The diagram shows the specific structure of the sliding block 2. The sliding block 2 is also provided with a second protrusion 22 at the tail end. A fourth groove 23 is opened on the second protrusion 22. A second countersunk hole 221 is opened on the second protrusion 22. A third round hole 25 is also opened on both sides of the fourth groove 23. A fifth groove 213 is also opened at the front end of the sliding block 2. A third guide structure 212 is provided on the fifth groove 213. A second chamfer 24 is also provided at the front end of the fifth groove 213.

[0076] The fourth groove 23 has symmetrical third circular holes 25 on both sides, and the fifth groove 213 has two second chamfers 24 at the front end. These two chamfers are symmetrically arranged along the center position of the sliding block 2.

[0077] To achieve automatic reset of the pull bar, such as Figure 15As shown, the unlocking device also includes a spring 4 and a spring fixing block 5. The front end of the spring fixing block 5 is provided with a fourth circular hole 51. One end of the spring 4 is installed in the fourth circular hole 51, and the other end of the spring 4 is installed in the two third circular holes 25 at the tail of the sliding block 2. The spring fixing block 5 is also provided with a sixth groove 52 and a seventh groove 53 of different depths.

[0078] The fourth circular hole 51 is symmetrically arranged on both sides of the front end of the spring fixing block 5. There are two springs 4. One end of the spring 4 is symmetrically placed in the fourth circular hole 51, and the other end of the spring 4 is placed in the third circular hole 25 on the sliding block 2. The spring fixing block is fixed to the movable plate by screws. The sixth groove 52 and the seventh groove 53 descend in a stepped manner. The seventh groove 53 is used to increase the backward movement distance of the sliding block 2 when it is pulled.

[0079] like Figure 16 As shown, the unlocking device also includes a sliding bar 7, which includes a molding structure 71 and a strip 72. The molding structure 71 is provided with a third countersunk hole 711; the strip 72 is provided with a third protrusion 721. The molding structure 71 is connected to the fourth groove 23 on the sliding block 2, and the strip 72 is placed in the sixth groove 52 of the spring fixing block 5.

[0080] The sliding bar 7 is provided with a widened tail structure 73, and a fourth countersunk hole 732 is provided on the tail structure 73.

[0081] Specifically, such as Figure 17 As shown, the unlocking device further includes a pressure block 8, which has an eighth groove 81 for placing the sliding bar 7 therein. The pressure block 8 is placed between the third protrusion 721 on the sliding bar 7 and the tail structure 73, and is fixed to the movable plate. The unlocking device also includes... Figure 18 The handle 9 shown has a fifth countersunk hole 91, which is used to match the fourth countersunk hole 732 and to connect the sliding bar 7 and the handle 9.

[0082] Assemble the components as described above, such as Figure 19 As shown, the various components are connected. When the handle 9 is pulled, the sliding block 2 moves backward. Since the pressure block 8 is stuck at the third protrusion 721, the maximum pulling distance of the handle 9 is limited. At the same time, the spring 4 is also compressed. When the handle 9 is released, the spring 4 extends. Thus, the entire device completes its reset.

[0083] When locked, the diameter of the second cylinder 314 is smaller than the opening diameter of the fixing plate 1, and the size corresponding to the first notch 102 on the fixing plate 1 is smaller than the diameter of the second cylinder 314.

[0084] Wherein, the diameter L3 of the second cylinder 314 on the sliding column 31 is smaller than the opening diameter D1 of the fixed plate 1, so that the bottom of the sliding column 31 fits against the bottom of the movable plate after it descends. In addition, the dimension L1 corresponding to the first notch 102 on the fixed plate 1 is smaller than the diameter L3 of the second cylinder 314, so as to prevent the latch from coming out of the fixed plate 1.

[0085] In this embodiment, after the movable plate is inserted into the chassis slot, the fixing plate mounted on the chassis will press against the sliding post mounted on the movable plate. The sliding post 31 will rise accordingly until it is pushed to the center of the first circular hole 101 and falls into the hole, thereby locking the latch body 3 into the groove on the fixing plate inside the chassis, thus achieving a fixed installation. When it is necessary to remove the movable plate, simply pull the handle 9 outward by hand. The sliding block 2 will press against the sliding post 31, and the sliding post 31 will rise accordingly, allowing the movable plate to be easily pulled out of the chassis. Whether unlocking or locking, there is no need to install or remove the non-removable screws. The entire installation and disassembly process is very convenient and optimizes the production process.

[0086] Example 2:

[0087] The above embodiment 1 provides an unlocking device for a movable disk, and its specific usage method is as follows: Figure 20 As shown, it includes:

[0088] Step 101: When locking, the first chamfer 11 presses against the second inclined surface 312 to move the sliding post 31 upward until the bottom of the sliding post 31 is higher than the top of the substrate 10, and the sliding post 31 is pushed to the center position of the first circular hole 101.

[0089] In actual use, the fixing plate 1 is fixed inside the chassis, the locking body 3 is fixed on the movable plate and placed in the first groove 21 of the sliding block 2, the movable plate is pushed close to the chassis, the first chamfer 11 presses against the second inclined surface 312, and under the action of the pressing force, the sliding column 31 moves upward.

[0090] The sliding column 31 moves upward until its bottom disengages from the movable plate and is higher than the base plate 10 on the fixed plate 1. It continues to advance until the sliding column 31 enters the first circular hole 101, thereby achieving locking.

[0091] Step 102: When unlocking, the first guide structure 211 presses the first inclined surface 311, and the first inclined surface 311 receives external force until the bottom of the sliding post 31 is higher than the substrate 10, and the bottom of the sliding post 31 is dislodged from the substrate 10.

[0092] When unlocking is required, pull the handle 9 backward, which will cause the sliding block 2 to move backward. At this time, the first guide structure 211 on the sliding block 2 will press the first inclined surface 311 on the sliding column 31. Under the action of the pressing force, the sliding column 31 will move upward.

[0093] The sliding column 31 moves upward until its bottom is higher than the substrate 10 on the substrate fixing plate 1. Under the action of the locking spring 33 inside the sliding column 31, the second cylindrical part 314 at the bottom of the sliding column 31 will disengage from the fourth notch 132 of the fixing plate 1, and pull the entire movable plate out of the chassis slot, thus unlocking.

[0094] For details on the specific structure of the unlocking device, please refer to Embodiment 1, which will not be repeated here.

[0095] In this embodiment, according to the unlocking device provided in Embodiment 1 and the method of using the unlocking device provided in Embodiment 2, the unlocking device is applied to the installation of the movable plate. When the movable plate is inserted into the slot of the chassis, the second inclined surface 312 of the sliding column 31 rises under the action of the extrusion force and is locked into the first round hole 101, thus achieving fixed installation. When it is necessary to remove the movable plate, by pulling the sliding block 2, the first guide structure 211 on the sliding block 2 extrudes the first inclined surface 311 of the sliding column 31, and the sliding column 31 will also be lifted accordingly, and it will be released from the fourth notch 132 to complete the unlocking. The movable plate can be conveniently pulled out of the chassis. The entire installation and disassembly process is very convenient, optimizes the production process, and improves production efficiency.

[0096] Those skilled in the art will readily understand that the above description is merely 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 scope of protection of the present invention.
