[0030] See also Figure 1 , Figure 1 It is a structural schematic diagram of an embodiment of a board and card fixing device provided in the present application.

[0031] The present application provides a board fixing device. Figure 1 and Figure 2 As shown, the board fixing device of this embodiment includes a machine frame 10, a fixing assembly 20, a rotating member 30, and a handle 40. The fixing assembly 20 is connected to the machine frame 10, the handle 40 is movably connected to the fixing assembly 20 and / or the rotating member 30, and the rotating member 30 is movably connected to the fixing assembly 20 and / or the handle 40, wherein the handle 40 drives the rotating member 30 to move relative to the fixing assembly 20, and the rotation direction of the handle 40 is opposite to the rotation direction of the rotating member 30.

[0032] In an optional embodiment, the fixed component 20 is fixedly connected to the machine frame 10, the rotating member 30 is rotationally connected to the fixed component 20, and the handle 40 is rotationally connected to the fixed component 20, and the handle 40 is fixedly connected to the rotating member 30. Therefore, when installing the external component 50 on the machine frame 10, the user can rotate the handle 40 to drive the rotating member 30 rotationally connected to the fixed component 20 to rotate, so that the rotating member 30 squeezes the external component 50 on the machine frame 10, and the external component 50 is clamped by the rotating member 30 cooperating with the machine frame 10, so that the external component 50 can be simply and quickly fixed to the machine frame 10, wherein the external component 50 can be a board, and the present application does not make specific limitations here.

[0033] Specifically, when the external component 50 needs to be pressed against the frame 10, the user can rotate the handle 40 toward the end close to the frame 10 and around the circumferential direction of the fixing assembly 20. At this time, the rotating member 30 rotates in the circumferential direction of the fixing assembly 20 in the opposite direction to the rotation direction of the handle, that is, the rotating member 30 gradually approaches the frame 10 during rotation. After the external component 50 has been attached to the frame 10, the rotating member 30 can press and fix the external component 50 on the frame 10. The handle 40 is movably connected to the frame 10. After the external component 50 is fixed to the frame 10, the handle 40 can be fixed to the frame 10, thereby preventing the rotating member 30 from loosening. When the external component 50 needs to be removed from the frame 10, the user removes the handle 40 from the frame 10, and rotates the handle 40 toward the end away from the frame 10 around the circumferential direction of the fixing assembly 20. At this time, the rotating member 30 rotates around the circumferential direction of the fixing assembly 20 in the opposite direction to the rotation direction of the handle, that is, the rotating member 30 gradually moves away from the frame 10 during rotation, so that the rotating member 30 is separated from the frame 10, and the external component 50 can be removed from the frame 10. That is, the external component 50 can be installed or removed without the aid of tools, so that the external component 50 can be pressed and fixed on the frame 10, and the external component 50 can be quickly and conveniently removed from the frame 10, wherein the rotating member 30 and the handle 40 can be connected in a gear meshing manner, so that the handle 40 rotates to drive the rotating member 30 to rotate in the opposite direction of the handle 40, and the present application does not make specific limitations here.

[0034] In the above embodiment, the user rotates the handle 40 toward the end away from the frame 10 around the circumferential direction of the fixed component 20, and the handle 40 can drive the rotating member 30 to rotate around the circumferential direction of the fixed component 20 in a direction opposite to the rotation direction of the handle 40, so that the external component 50 is clamped and fixed on the frame 10 by the rotating member 30. By rotating the handle 40 in the opposite direction, the external component 50 can be easily removed from the frame 10, and the external component 50 can be simply and quickly installed without the aid of tools.

[0035] In an optional embodiment, if Figure 1 and Figure 4As shown, the machine frame 10 includes a main body 101 and a baffle 102 connected to the main body 101. The baffle 102 is arranged on the main body 101 of the machine frame 10, and the fixing component 20 can be installed on the main body 101 and / or the baffle 102, wherein the fixing component 20 can be installed on the main body 101 alone, or can be installed on the baffle 102 alone, and the present application does not make specific limitations here. A first connecting portion 103 is arranged on the main body 101, and a second connecting portion 404 is arranged on the handle 40. The first connecting portion 103 and the second connecting portion 404 can be detachably matched so that the handle 40 can be locked on the main body 101 or detached from the main body 101. In other embodiments, the external component 50 can be clamped on the end face of the baffle 102 on the side facing the fixing component 20. Further, as Fig.10 As shown, a notch 108 is provided on the baffle 102, so that a portion of the rotating member 30 can pass through the notch 108, that is, a portion of the rotating member 30 can be located inside the notch 108, so that the rotating member 30 clamps or detaches from the external component 50. In an optional embodiment, when the external component 50 is pressed and fixed on the baffle 102, the handle 40 is rotated toward the end close to the frame 10 around the circumferential direction of the fixing assembly 20, and a portion of the rotating member 30 is located inside the notch 108, so that the rotating member 30 clamps the external component on the baffle 102, and when the external component 50 is removed from the baffle 102, the rotating member 30 partially detaches from the notch 108.

[0036] In an optional embodiment, if Figure 1 and Figure 4As shown, a first slot (not shown) is formed between the first connection part 103 and the main body 101; the handle 40 includes a rotating rod 401, an elastic member 402 and a snap-on button 403. A receiving space (not shown) for receiving the elastic member 402 is provided in the rotating rod 401. A snap-on button 403 connected to the elastic member 402 is slidably connected at the opening of the receiving space. A second connection part 404 is provided on the snap-on button 403. A second slot (not shown) is formed between the snap-on button 403 and the second connection part 404. The first slot and the second slot are detachably connected. The first connection part 103 and the second connection part 404 are snap-connected to achieve detachable cooperation. Therefore, the first connection part 103 can be snap-connected to the second connection part 404. When the external component 50 is installed, the first connection part 103 can be snap-connected to the second connection part 404, thereby locking the handle 40 and the rotating member 30 to prevent the rotating member 30 from rotating and causing the external component 50 to loosen. When the external component 50 is disassembled, the first connection portion 103 can be disassembled from the second connection portion 404, and the handle 40 is fixed to the main body 101 of the frame 10, so that the rotating member 30 can be prevented from loosening. Specifically, the elastic member 402 in the rotating rod 401 can push the clamping button 403 to slide at the opening of the accommodating space of the rotating rod 401, and the second connection portion 404 is provided on the clamping button 403, so that the clamping button 403 can drive the handle 40 to be fixed to the frame 10 or be disassembled from the frame 10. When the user fixes and presses the external component 50, the user rotates the handle 40 so that the axial direction of the rotating rod 401 is parallel to the end face of the main body 101 of the frame 10, so that the rotating member 30 presses the external component 50 against the baffle 102. At this time, the user can press the snap button 403 so that the snap button 403 moves in the rotating rod 401 toward the baffle 102. The user releases the snap button 403, and the elastic member 402 in the rotating rod 401 pushes the snap button 403 to pop out, so that the first connecting portion 103 on the first button is inserted into the first slot, and the first slot is matched with the second slot to connect, thereby locking the handle 40 on the frame 10. When the user removes the external component 50, the user can press the snap-on button 403 to disengage the first connecting portion 103 on the snap-on button 403 from the first snap-on slot, and rotate the handle 40 to disengage the rotating member 30 from the baffle 102 of the frame 10, thereby removing the external component 50 from the baffle 102. In other embodiments, the snap-on button 403 can be configured as a toggle block, which is disposed on the side of the rotating rod 401 facing the main body 101, and the present application does not make any specific limitations thereon.

[0037] In a specific embodiment, Figure 6As shown, a pressing cap 4031 is provided on the snap-on button 403, and a boss structure 4032 is provided on the end face of the snap-on button 403 facing the main body 101. The side of the boss structure 4032 close to the second connecting part 404 is set as an inclined surface, and the side of the second connecting part 404 close to the pressing cap 4031 can also be set as an inclined surface. Therefore, when the handle 40 is locked on the main body 101, the second connecting part 404 on the snap-on button 403 can be automatically engaged with the first connecting part 103, so that the handle 40 is automatically engaged with the main body 101. When removing the external component 50, the user presses the pressing cap 4031 to make the second connecting part 404 disengage from the first connecting part 103, thereby making the handle 40 disengage from the main body 101, and then the handle 40 can be rotated to remove the external component 50.

The projection of the first slide groove 2012 coincides with the second slide groove 2022, and the rotating member 30 is inserted into the first slide groove 2012 and the second slide groove 2022. When the user rotates the handle 40, the handle 40 can rotate along the axial direction of the first rotating structure 2011 and the second rotating structure 2021, thereby driving the rotating member 30 to move in the first slide groove 2012 and the second slide groove 2022. The first slide groove 2012 and the second slide groove 2022 can limit the rotating member 30, wherein the direction and length of the first slide groove 2012 and the second slide groove 2022 can be set according to the needs of clamping or disassembling the external component 50, and the present application does not limit it here.

[0040] In an optional embodiment, a third rotating structure 405 and a fourth rotating structure 406 on the same axis are disposed at opposite ends of the handle 40. The third rotating structure 405 is rotationally connected to the first rotating structure 2011, and the fourth rotating structure 406 is rotationally connected to the second rotating structure 2021. A fifth rotating structure 407 parallel to the axis of the third rotating structure 405 is disposed on the handle 40, and the fifth rotating structure 407 is rotationally connected to the rotating member 30. Therefore, by disposing the third rotating structure 405 and the fourth rotating structure 406, the handle 40 can rotate along the axis of the first rotating structure 2011 and the second rotating structure 2021. The handle 40 is provided with a fifth rotating structure 407 parallel to the axis of the third rotating structure 405. The handle 40 is rotated along the axis of the first rotating structure 2011 and the second rotating structure 2021, which can drive the rotating member 30 to rotate along the axis of the fifth rotating structure 407. The rotating member 30 can fix and remove the external component 50.

[0041] In an optional embodiment, if Fig. 9As shown, the rotating member 30 includes a rotating portion 301, a third connecting portion 302 and a clamping portion 303. The rotating portion 301 is connected to the clamping portion 303 through the third connecting portion 302. The rotating portion 301 has a sixth rotating structure 304 and a seventh rotating structure 305 on the same axis arranged at opposite ends thereof. The sixth rotating structure 304 and the seventh rotating structure 305 are inserted into the first sliding groove 2012 and the second sliding groove 2022, respectively. The rotating portion 301 is provided with an eighth rotating structure 306 parallel to the axis of the sixth rotating structure 304. The eighth rotating structure 306 is provided on the rotating portion 301. 06 is rotationally connected to the fifth rotating structure 407, wherein the eighth rotating structure 306 can be a through hole, so as to be rotationally connected to the sixth rotating structure 304 on the handle 40, and the eighth rotating structure 306 can also be set as a blind hole close to the second fixed portion 202, so as to be rotationally connected to the sixth rotating structure 304 on the handle 40, the sixth rotating structure 304 and the seventh rotating structure 305 can be set as cylindrical protrusions, and can also be set as other structures that are convenient for sliding inside the first slide groove 2012 and the second slide groove 2022, and the present application does not make specific limitations here. Therefore, the sixth rotating structure 304 and the seventh rotating structure 305 can slide inside the first sliding groove 2012 and the second sliding groove 2022 respectively, wherein the eighth rotating structure 306 is rotationally connected with the fifth rotating structure 407. When the user clamps the external component 50 on the baffle 102, the handle 40 is rotated to make the fifth rotating structure 407 rotate around the axis direction of the first rotating structure 2011 and the second rotating structure 2021, and the fifth rotating structure 407 drives the rotating part 301 to rotate, and the sixth rotating structure 304 and the seventh rotating structure 305 on the rotating part 301 slide inside the first sliding groove 2012 and the second sliding groove 2022 respectively, thereby driving the clamping part 303 to press the external component 50 against the baffle 102. Reverse rotation of the handle 40 can make the sixth rotating structure 304 and the seventh rotating structure 305 on the rotating part 301 slide in the first sliding groove 2012 and the second sliding groove 2022 respectively, thereby removing the external component 50 from the baffle 102.

[0042] It should be noted that the handle 40 is connected to the rotating rod 401 through a supporting boss (not shown in the figure), the fifth rotating structure 407 is arranged on the supporting boss, and the rotating part 301 of the rotating member 30 is connected to the supporting boss. The height of the supporting boss and the rotating part 301 is the same as the height between the first fixed part 201 and the second fixed part 202, so as to facilitate the first fixed part 201 and the second fixed part 202 to fix the handle 40 and the rotating member 30.

[0043] In an optional embodiment, the first rotating structure 2011, the second rotating structure 2021 and the fifth rotating structure 407 are respectively with one of the third rotating structure 405, the fourth rotating structure 406 and the eighth rotating structure 306 as a cylindrical protrusion, and the other is a circular hole. Therefore, the first rotating structure 2011 and the third rotating structure 405, the second rotating structure 2021 and the fourth rotating structure 406, the fifth rotating structure 407 and the eighth rotating structure 306 can cooperate with each other, one of which is set as a cylindrical protrusion and the other is a circular hole. For example, the first rotating structure 2011 is set as a cylindrical protrusion and the third rotating structure 405 is set as a circular hole, that is, the first rotating structure 2011 is inserted into the third rotating structure 405, so that the first rotating structure 2011 can rotate inside the third rotating structure 405, wherein the first rotating structure 2011 can also be set as a circular hole, and the third rotating structure 405 is set as a cylindrical protrusion, which is not specifically limited in this application. The rest is the same as the above-mentioned first rotating structure 2011 and the third rotating structure 405, and will not be repeated here.

[0044] In an optional embodiment, if Figure 5 As shown, the end surface of the handle 40 close to the fifth rotating structure 407 is set as two inclined surfaces with preset angles. Therefore, by setting two inclined surfaces on the end surface of the handle 40 close to the fifth rotating structure 407, the handle 40 can drive the rotating member 30 to rotate, and the rotating part 301 of the rotating member 30 can be rotatably connected to the fifth rotating structure 407 to avoid the rotating part 301 on the rotating member 30 from getting stuck. Among them, the preset angles of the two inclined surfaces can be set to angles that facilitate the rotation of the rotating part 301, and this application does not make specific restrictions here.

[0045] In an optional embodiment, if Figure 5As shown, a toggle portion 408 is provided at one end of the handle 40 close to the rotating member 30, and the toggle portion 408 is used to push out the external component 50 to make it separate from the frame 10 when the end of the handle 40 away from the rotating member 30 is rotated in a direction away from the frame 10. Therefore, by providing the toggle portion 408 on the handle 40, when it is necessary to remove the external component 50, the user rotates the handle 40 so that the end of the handle 40 away from the rotating member 30 is rotated in a direction away from the frame 10, and at this time, the handle 40 drives the clamping portion on the rotating member 30 to gradually move away from the baffle 102 so that the clamping portion 303 is separated from the baffle 102, and at this time, the toggle portion 408 on the handle 40 can push the external component 50 to push the external component 50 out of the baffle 102 of the frame 10, so that the external component 50 can be easily removed, reducing the subsequent steps of removing the external component 50 from the baffle 102.

[0046] In a specific embodiment, when the user needs to fix the external component 50 on the baffle 102 of the frame 10, the user can rotate the handle 40 toward the end close to the frame 10 and rotate it around the circumferential direction of the fixing assembly 20, and the third rotating structure 405 and the fourth rotating structure 406 on the handle 40 rotate in the first rotating structure 2011 on the first fixing part 201 and the second rotating structure 2021 on the second fixing part 202 respectively, and the fifth rotating structure 407 on the handle 40 drives the rotating part 301 to rotate, and the rotating The sixth rotating structure 304 and the seventh rotating structure 305 on the part 301 move in the first sliding groove 2012 and the second sliding groove 2022 respectively, that is, the rotating member 30 rotates in the direction opposite to the rotation direction of the handle 40, so that the clamping part 303 on the rotating member 30 rotates, and the clamping part 303 can press and fix the external component 50 on the baffle 102, and the second connecting part 404 on the snap-in button 403 is automatically snapped onto the first connecting part 103 on the main body 101, thereby achieving the effect of fixing the external component 50. When the user needs to remove the external component 50 from the baffle 102 of the frame 10, the user can press the button cap 4031 on the snap-on button 403 to disengage the second connection portion 404 from the first connection portion 103, rotate the handle 40 toward the end away from the frame 10 around the circumferential direction of the fixing assembly 20, and rotate the rotating member 30 in the direction opposite to the rotation direction of the handle 40, so that the clamping portion 303 is disengaged from the baffle 102, and the external component 50 can be removed from the baffle 102.

[0047] In the above manner, the present application can clamp and fix the external component 50 on the baffle 102 of the frame 10 by the rotating member 30 by setting the fixing assembly 20 on the frame 10 and rotating the connecting handle 40 and the rotating member 30 in the fixing assembly 20, and can prevent the rotating member 30 from loosening by fixing the handle 40 on the frame 10, so that the external component 50 can be simply and quickly installed or removed without the help of tools. By setting the first connecting part 103 on the main body 101 and the second connecting part 404 on the handle 40, the first connecting part 103 and the second connecting part 404 can cooperate with each other to lock or remove the handle 40. By setting the rotating rod 401, the elastic member 402 and the snap button 403 on the handle 40, the handle 40 can be automatically snapped on the main body 101 by the snap button 403. By rotatably connecting the rotating member 30 and the handle 40 to the first fixed part 201 and the second fixed part 202, and providing the first slide groove 2012 and the second slide groove 2022, the rotating member 30 can be driven to rotate around the axis direction of the fixed component 20 by rotating the handle 40, so that the rotating member 30 moves inside the first slide groove 2012 and the second slide groove 2022, thereby limiting the rotating member 30. By providing the third rotating structure 405, the fourth rotating structure 406 and the fifth rotating structure 407 on the handle 40, the handle 40 can be rotated around the axis direction of the third rotating structure 405, so that the rotating member 30 is driven to rotate by the fifth rotating structure 407. By providing the sixth rotating structure, the seventh rotating structure 305 and the eighth rotating structure 306 on the rotating part 301 of the rotating member 30, the eighth rotating structure 306 rotates around the fifth rotating structure 407, so that the rotating part 301 moves in the first slide groove 2012 and the second slide groove 2022, so that the clamping part 303 clamps the external component 50. By providing two inclined surfaces at preset angles on the handle 40, the situation that the rotating part 301 gets stuck when rotating can be avoided. By providing a toggle part 408 at one end of the handle 40 close to the rotating member 30, the toggle part 408 can toggle the external component 50 to push the external component 50 out, so that it is easier and faster to remove the external component 50. By providing a notch 108 on the baffle 102 and providing the third connecting part 302 as a T-shaped structure, the third connecting part 302 can move in the notch 108, so that it is convenient for the clamping part 303 to clamp the external component 50.
