[0026] See also Figure 1 and Figure 2 The screw locking fixture 100 includes a base 1, a rotating frame 2 and a cover plate 3. The rotating frame 2 is rotatably set on the base 1, and the cover plate 3 is detachably installed on the rotating frame 2. The base 1 is provided with a receiving groove 11, and the receiving groove 11 is used to accommodate the accessory 200 to be locked, wherein the accessory 200 to be locked has at least one screw hole 201, and the screw hole 201 needs to be tightened with a screw. The rotating frame 2 is provided with a mounting port 21, and when the cover plate 3 is installed on the rotating frame 2, the cover plate 3 covers the mounting port 21. At least one through hole 31 is provided on the cover plate 3. Specifically, the number of mounting holes on the cover plate 3 corresponds to the screw holes 201 on the accessory 200 to be locked, and the through holes 31 correspond one-to-one to the screw holes 201. When the rotating frame 2 rotates to the first position relative to the base 1, as shown Figure 1As shown, the cover plate 3 and the rotating frame 2 jointly cover the receiving groove 11, and along the first direction X, the projection of the screw hole 201 is located in the through hole 31, and the first direction X is perpendicular to the bottom wall of the receiving groove 11. At this time, the screw can be inserted into the screw hole 201 through the through hole 31 on the cover plate 3, and then the screw can be tightened into the screw hole 201 using a tool such as an electric screwdriver or a screwdriver to achieve the locking of the accessory 200 to be locked; when the rotating frame 2 is rotated to the second position relative to the base 1, as shown Figure 3 As shown, the receiving slot 11 is opened and exposed to the outside. At this time, the accessory 200 to be locked in the receiving slot 11 can be taken out or the accessory 200 to be locked can be put into the receiving slot 11 to replace the accessory 200 to be locked. In this embodiment, a receiving groove 11 for accommodating the accessory 200 to be locked is provided on the base 1, the rotating frame 2 is rotatably set on the base 1, a mounting opening 21 is provided on the rotating frame 2, and the cover plate 3 is detachably installed on the rotating frame 2 and covers the mounting opening 21, and at least one through hole 31 is provided on the cover plate 3. When the rotating frame 2 is rotated to the first position relative to the base 1, the cover plate 3 and the rotating frame 2 jointly cover the receiving groove 11, and along the first direction X, the projection of the screw hole 201 on the accessory 200 to be locked is located in the through hole 31, so that the screw can be placed from the through hole 31 into the screw hole 201, and the screw can be tightened using a tool such as an electric screwdriver or a screwdriver, thereby reducing the risk of scratching or damaging the accessory 200 to be locked by a tool such as an electric screwdriver or a screwdriver during the process of tightening the screw; when the rotating frame 2 is rotated to the second position, the receiving groove 11 is exposed to the outside world, and at this time the accessory 200 to be locked in the receiving groove 11 can be taken out or the accessory 200 to be locked can be placed in the receiving groove 11.

[0027] It is worth noting that the accessory 200 to be locked can be a combination of a circuit board and an electronic component or a combination of a circuit board and a housing. Among them, taking the example of the accessory 200 to be locked being a combination of a circuit board and an electronic component, the electronic component needs to be fixed to the circuit board by screws. Therefore, the accessory 200 to be locked can use the screw locking fixture 100 of the present application to assist in fixing the electronic component to the circuit board, thereby reducing the risk of tools such as electric screwdrivers or screwdrivers scratching or damaging the circuit board. It is understandable that the accessory 200 to be locked may also not include a combination of circuit boards, and it can be any component or combination of components that needs to be locked with screws, and this application does not limit this.

[0028] In some embodiments, the cover plate 3 is made of acrylic material, so that the cover plate 3 has a certain degree of transparency. When the user uses the screw locking fixture 100 of the present application to lock the accessory 200 to be locked, the user can observe the situation inside the accommodating cavity through the cover plate 3, which is beneficial to reduce the risk of defects during screw locking.

[0029] In some embodiments, the cover plate 3 and the rotating frame 2 are detachably connected via screws (not shown).

[0030] In some embodiments, see Figure 2 and Figure 3 The screw locking jig 100 also includes a mounting base 4, which is detachably mounted on the base 1 and accommodated in the accommodating groove 11. The mounting base 4 is provided with a mounting groove 41, which is provided on the surface of the mounting base 4 facing the cover plate 3, and the mounting groove 41 is used to accommodate the accessory 200 to be locked. When the rotating frame 2 is rotated to the first position, the rotating frame 2 and the cover plate 3 jointly cover the mounting groove 41, and at this time, along the first direction X, the projection of the screw hole 201 on the accessory 200 to be locked is located in the through hole 31 on the cover plate 3, and when the number of the screw hole 201 and the through hole 31 is multiple, the screw hole 201 and the through hole 31 correspond one to one. At this time, the screw can be placed into the screw hole 201 through the through hole 31, and then the screw can be tightened. Since the cover plate 3 can be detachably mounted on the rotating frame 2, in this embodiment, a mounting base 4 is provided, and the mounting base 4 can be detachably mounted on the base 1. When it is necessary to lock screws of different types of accessories 200 to be locked, the mounting base 4 and the cover plate 3 of the corresponding type can be replaced. In this way, there is no need to redesign the entire screw locking jig 100, which increases the application range of the screw locking jig 100 and saves costs.

[0031] In some embodiments, the diameter of the through hole 31 is larger than the nominal diameter of the screw hole 201 , and the diameter of the through hole 31 is larger than the maximum diameter of the screw, so that the screw can pass through the through hole 31 and be screwed and fixed to the screw hole 201 of the accessory 200 to be locked.

[0032] In some embodiments, the base 1 is provided with a first positioning pin 12, one end of which is connected to the bottom wall of the receiving groove 11. The mounting base 4 is provided with a first positioning hole 42, which is located on the surface of the mounting base 4 facing away from the mounting groove 41. When the mounting base 4 is installed on the base 1, the first positioning pin 12 is plugged into the first positioning hole 42, thereby achieving positioning between the mounting base 4 and the base 1.

[0033] In some embodiments, in addition to setting the first positioning pin 12 on the base 1, the first positioning pin 12 can also be set on the mounting seat 4, which is not shown in the figure. At this time, the first positioning hole 42 is set on the mounting seat 4, and the first positioning hole 42 is connected to the bottom wall of the accommodating groove 11.

[0034] In some embodiments, see Figure 2 When viewed along the first direction X, the shape of the accommodating groove 11 is roughly rectangular, and the first positioning pin 12 is set away from the center of the rectangle. Such a setting can form a fool-proof structure, which can reduce the risk of installation errors in the relative position between the mounting seat 4 and the accommodating groove 11.

[0035] In some embodiments, there are multiple first positioning pins 12 and first positioning holes 42, and multiple first positioning pins 12 are spaced apart on the bottom wall of the accommodating groove 11. Multiple first positioning holes 42 correspond one-to-one to multiple first positioning pins 12, and a first positioning pin 12 is plugged into a first positioning hole 42, thereby improving the positioning accuracy between the mounting seat 4 and the base 1.

[0036] In some embodiments, see Figure 1 and Figure 2 One end of the rotating frame 2 is provided with a first lug 22 and a second lug 23. The first lug 22 and the second lug 23 are spaced apart along a second direction Y, which is perpendicular to the first direction X. The first lug 22 is provided with a first rotation hole 221, and the second lug 23 is provided with a second rotation hole 231. The first rotation hole 221 and the second rotation hole 231 are coaxial. One end of the base 1 is provided with a first flange 13. The first flange 13 is provided with a third rotation hole 131. The third rotation hole 131 is located between the first rotation hole 221 and the second rotation hole 231. The screw locking jig 100 also includes a rotating rod 5. The rotating rod 5 passes through the first rotation hole 221, the third rotation hole 131, and the second rotation hole 231 in sequence, so that the rotating frame 2 can rotate around the rotating rod 5 relative to the base 1. In this embodiment, by positioning the third rotating hole 131 between the first rotating hole 221 and the second rotating hole 231, that is, positioning the first flange 13 between the first lug 22 and the second lug 23, the first lug 22 and the second lug 23 can limit the movement of the rotating frame 2 along the second direction Y, thereby reducing the risk of the through hole 31 on the cover plate 3 and the screw hole 201 on the accessory 200 to be locked being misaligned and unable to lock the screw when the rotating frame 2 is rotated to the first position.

[0037] In some embodiments, see Figure 1 and Figure 2One end of the rotating frame 2 is provided with a third lug 24 and a fourth lug 25. The third and fourth lugs 24, 25 are spaced apart along the second direction Y, and the first lug 22, second lug 23, third lug 24, and fourth lug 25 are arranged along the second direction Y. The third lug 24 is provided with a fourth rotation hole 241, and the fourth lug 25 is provided with a fifth rotation hole 251. The fourth rotation hole 241 and the fifth rotation hole 251 are coaxial. The base 1 is provided with a second flange 14. The second flange 14 is spaced apart from the first flange 13 along the second direction Y. The second flange 14 is provided with a sixth rotation hole 141, which is located between the fourth rotation hole 241 and the fifth rotation hole 242. The rotating rod 5 also passes through the fourth rotation hole 241, the sixth rotation hole 141, and the fifth rotation hole 251, so that the rotating frame 2 can rotate relative to the base 1 about the rotating rod 5. In this embodiment, by passing the rotating rod 5 through the fourth rotating hole 241, the sixth rotating hole 141, and the fifth rotating hole 251, that is, the rotating rod 5 passes through the first rotating hole 221, the third rotating hole 131, the second rotating hole 231, the fourth rotating hole 241, the sixth rotating hole 141, and the fifth rotating hole 251 in sequence, the stability of the rotating frame 2 during rotation about the rotating rod 5 can be improved. In this embodiment, by positioning the sixth rotating hole 141 between the fourth rotating hole 241 and the fifth rotating hole 242, that is, positioning the second flange 14 between the third lug 24 and the fourth lug 25, the third lug 24 and the fourth lug 25 can jointly restrict movement of the rotating frame 2 in the fourth direction, further reducing the risk of misalignment between the through hole 31 on the cover plate 3 and the screw hole 201 on the accessory 200 to be locked, resulting in a failure to lock the screw when the rotating frame 2 is rotated to the third position.

[0038] In some embodiments, see Figure 1 and Figure 3 The screw locking fixture 100 includes a supporting gas rod 6, one end of which is connected to the base 1, and the other end is connected to the rotating frame 2. The supporting gas rod 6 is used to support the rotating frame 2 so that the rotating frame 2 remains in the second position. In this embodiment, the rotating frame 2 is maintained in the second position by the supporting gas rod 6. In the process of installing the accessory 200 to be locked into the installation slot 41, the risk of the rotating frame 2 and the cover plate 3 covering the installation slot 41 under the action of gravity can be reduced, so that the accessory 200 to be locked can be smoothly installed in the installation slot 41. It is worth noting that although the supporting gas rod 6 can keep the rotating frame 2 in the second position, after human intervention, the rotating frame 2 can break through the supporting force of the support rod and rotate the rotating frame 2 to the first position.

[0039] In some embodiments, the supporting gas rod 6 includes a telescopic rod 61 and an outer sleeve 62. The telescopic rod 61 extends into the outer sleeve 62 and can slide along the outer sleeve 62, thereby forming a telescopic effect. One end of the outer sleeve 62 is connected to the base 1, and the end of the telescopic rod 61 protruding from the outer sleeve 62 is connected to the rotating frame 2. During the process of rotating the rotating frame 2 from the second position to the first position, the space inside the outer sleeve 62 is gradually occupied by the telescopic rod 61, so that the air inside the outer sleeve 62 is gradually compressed, and then the air inside the outer sleeve 62 generates a force on the telescopic rod 61. This force makes the telescopic rod 61 tend to extend from the outer sleeve 62. Therefore, the supporting gas rod 6 can keep the rotating frame 2 in the second position.

[0040] In some embodiments, see Figure 1 and Figure 4 The screw locking fixture 100 includes a locking member 7, which is slidably disposed on the base 1 and can slide between a third position and a fourth position relative to the base 1. When the rotating frame 2 is in the first position and the locking member 7 is in the third position, as shown in FIG. Figure 1 As shown, along the first direction X, a portion of the rotating frame 2 is located between the locking member 7 and the base 1. At this time, the locking member 7 can limit the rotating frame 2 from rotating away from the first position, thereby achieving fixation between the rotating frame 2 and the base 1, and facilitating the screw locking operation of the accessory 200 to be locked in the mounting slot 41; when the locking member 7 slides from the third position to the fourth position, as shown in FIG. Figure 4 As shown, along the first direction X, the locking member 7 and the rotating frame 2 are staggered with each other. At this time, the locking member 7 cancels the limit on the rotating frame 2. Under the action of the supporting gas rod 6, the rotating frame 2 rotates from the first position to the second position, thereby opening the installation slot 41 to facilitate the removal of the accessory 200 to be locked in the installation slot 41 or the installation of the accessory 200 to be locked in the installation slot 41.

[0041] In some embodiments, see Figure 1 and Figure 4 The base 1 is provided with a slide groove 15, which is provided on the surface of the base 1 facing the cover 3 and is separated from the receiving groove 11. The locking member 7 is partially received in the slide groove 15, and the locking member 7 can slide in the slide groove 15 along the second direction Y, so that the locking member 7 can slide between the third position and the fourth position.

[0042] In some embodiments, see Figure 2 and Figure 4 , the locking member 7 is provided with a locking portion 71. When the rotating frame 2 is in the first position and the locking member 7 is in the third position, as shown in FIG. Figure 1As shown, along the first direction X, a portion of the rotating frame 2 is located between the locking portion 71 and the base 1. At this time, the locking portion 71 can limit the rotating frame 2 from rotating away from the first position, thereby achieving fixation between the rotating frame 2 and the base 1, and facilitating the screw locking operation of the accessory 200 to be locked in the mounting slot 41; when the locking member 7 slides from the third position to the fourth position, as shown in FIG. Figure 4 As shown, along the first direction X, the locking member 7 and the rotating frame 2 are staggered. At this time, the locking member 7 cancels the limit on the rotating frame 2. Figure 2 Along the first direction X, the surface of the locking portion 71 facing away from the base 1 is an arcuate surface 711, and when viewed along the third direction Z, the arcuate surface 711 protrudes away from the base 1. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other. In this embodiment, by configuring the surface of the locking portion 71 facing away from the base 1 as the arcuate surface 711, when the rotating frame 2 is rotated from the second position to the first position, the arcuate surface 711 can push the locking member 7 along the second direction Y to leave the third position, eliminating the need for manual movement of the locking member 7 away from the third position, which is very convenient.

[0043] In some embodiments, see Figure 1 and Figure 4 The rotating frame 2 is further provided with a gripping portion 26, which is located at an end away from the first lug 22. The gripping portion 26 is provided with a locking rod 261. When the rotating frame 2 is in the first position and the locking member 7 is in the third position, the locking rod 261 is located between the locking portion 71 and the base 1 in the first direction X, and the locking rod 261 abuts against the locking portion 71, thereby locking and fixing the rotating frame 2 and the base 1.

[0044] In some embodiments, see Figure 3 The base 1 is also provided with a second positioning pin 16, and the gripping portion 26 is provided with a second positioning hole 262. When the rotating frame 2 is rotated to the first position, the second positioning pin 16 is inserted into the second positioning hole 262, thereby improving the position accuracy between the rotating frame 2 and the base 1, and then improving the position accuracy between the through hole 31 on the cover plate 3 and the screw hole 201 on the accessory to be locked 200, so that the screw can smoothly pass through the through hole 31 and be placed in the screw groove.

[0045] In some embodiments, see Figure 3 The screw locking jig 100 includes a sensor 8, which is disposed on the surface of the base 1 facing the rotating frame 2. The sensor 8 is used to detect the position of the rotating frame 2. Specifically, when the sensor 8 detects that the rotating frame 2 is in the first position, the sensor 8 sends a signal indicating that the rotating frame 2 and the cover 3 are in place, and the user can perform the screw locking operation on the accessory 200 to be locked.

[0046] Furthermore, the screw locking jig 100 is provided with an indicator light (not shown), which is electrically connected to the sensor 8. When the sensor 8 detects that the rotating frame 2 is in the first position, the indicator light lights up, indicating that the user can perform the screw locking operation.

[0047] In an embodiment of the present invention, a receiving groove 11 for accommodating the accessory 200 to be locked is provided on the base 1, the rotating frame 2 is rotatably set on the base 1, a mounting opening 21 is provided on the rotating frame 2, and the cover plate 3 is detachably mounted on the rotating frame 2 and covers the mounting opening 21, and at least one through hole 31 is provided on the cover plate 3. When the rotating frame 2 is rotated to the first position relative to the base 1, the cover plate 3 and the rotating frame 2 jointly cover the receiving groove 11, and along the first direction X, the projection of the screw hole 201 on the accessory 200 to be locked is located in the through hole 31, so that the screw can be placed from the through hole 31 into the screw hole 201, and the screw can be tightened using a tool such as an electric screwdriver or a screwdriver, thereby reducing the risk of scratching or damaging the accessory 200 to be locked by a tool such as an electric screwdriver or a screwdriver during the process of tightening the screw; when the rotating frame 2 is rotated to the second position, the receiving groove 11 is exposed to the outside world, and at this time the accessory 200 to be locked in the receiving groove 11 can be taken out or the accessory 200 to be locked can be placed in the receiving groove 11.

[0048] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
