[0037] The embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0038] Figure 1 This is a schematic diagram of a system with a fixing device according to an embodiment of this application. Figure 1 As shown, the system 100 with a fixing device includes: a first device 101 having a first opening 1011, a second device 103, and a fixing device 102 installed in the first device through the first opening 1011. The first device 101 and the second device 103 are arranged adjacent to each other, and the system 100 with the fixing device achieves fixing between the first device 101 and the second device 103 by operating the fixing device 102.
[0039] Figure 2 This is a structural schematic diagram of a fixing device according to an embodiment of this application, showing the overall structure of the fixing device, as follows. Figure 2 As shown, the fixing device 102 includes an operating part 1021, a deformable part 1022, a rotating shaft part 1023, a connecting part 1024, and a fixing part 1025. The deformable part 1022 is a V-shaped body, with its two ends connected to the operating part 1021 and the rotating shaft part 1023, respectively. The rotating shaft part 1023 has a semi-circular rotational surface, which interacts with the rotating support part 1012 (see [reference]) within the first device 101, which has an arc-shaped cross-section. Figure 3 The connecting part 1024 connects the fixing part 1025 and the rotating shaft part 1023, and the fixing part 1025 can extend into the second device 103. Figure 2 The interior of (not shown).
[0040] Therefore, by pressing the operating part to rotate the shaft, the fixing part inside the second device can be rotated, thereby fixing the first and second devices. This embodiment achieves fixation through rotation, eliminating the need for pre-reserved translational space and improving operational convenience and user experience.
[0041] Figure 3 This is a partial schematic diagram of the fixing device installed in the first device according to an embodiment of this application, as shown below. Figure 3 As shown, when the operating part 1021 of the fixing device 102 is pressed, the rotating part 1023 and the fixing part 1025 are driven by the operating part 1021 to rotate in the first direction (i.e., Figure 3(rotating clockwise), the fixing part 1025 engages with the side wall of the second device 103 inside the second device 103 (see...). Figure 4 When the operating part 1021 of the fixing device 102 is pushed upward, the rotating part 1023 and the fixing part 1025 are driven by the operating part 1021 to rotate in the second direction (i.e., Figure 3 (rotating counterclockwise), the fixing part 1025 did not engage with the side wall of the second device 103 (see...). Figure 4 Therefore, operators can use simple operations, such as pressing or pushing the operating part, to rotate the rotating shaft and the fixing part, thereby fixing or not fixing the second device to the first device, improving the convenience of operation and the operator's experience.
[0042] In some embodiments, such as Figure 2 As shown, one end of the operating part 1021 is connected to the deformation part 1022, and the other end protrudes from the deformation part 1022 in a direction away from the rotating shaft part 1023. This increases the contact area, disperses the pressing pressure, improves the comfort of operation, and ensures that the operator can better control the operating part.
[0043] In some embodiments, the shape of the operating part 1021 may be a cuboid, a cylinder, or other shapes, and this application is not limited thereto.
[0044] In some embodiments, such as Figure 2 As shown, the operating part 1021 has multiple tooth-like protrusions on the side away from the rotating shaft part 1023 and / or the side away from the deformation part 1022. This increases the friction of the operating part, better assisting the operator in operating the fixing device. However, this application is not limited to this. The material of the operating part 1021 can be set to a material with a high coefficient of friction, such as rubber, to increase the friction of the operating part; or, the surface of the operating part 1021 can be sandblasted or etched to increase the surface roughness; or, anti-slip tape, a removable silicone sleeve, etc., can be provided on the surface of the operating part 1021 to increase the friction of the operating part.
[0045] In some embodiments, the deformable part 1022 is a V-shaped body, but this application is not limited to this; the deformable part 1022 may also be a U-shaped body or other shapes.
[0046] In some embodiments, the deformable part 1022 has a certain elasticity, and its material may be polyurethane (PU) or other elastic materials, but this application is not limited thereto.
[0047] In some embodiments, such as Figure 3As shown, a rotating support portion 1012 with an arc cross section is provided on the side wall adjacent to the second device 103 inside the first device 101. The rotating surface of the rotating shaft portion 1023 of the fixing device 102 can rotate on the rotating support portion 1012, and then drive the fixing portion 1025 to rotate through the connecting portion 1024, so as to fix the first device 101 and the second device 103 together.
[0048] In some embodiments, the connecting portion 1024 is elongated, with one end connected to the side of the rotating shaft portion 1023 located in the first device 101, and the other end connected to the middle portion of the fixing portion 1025 located in the second device 103. Thus, when the rotating shaft portion 1023 rotates, the fixing portion 1025 can be driven to rotate together through the connecting portion 1024.
[0049] In some embodiments, the length of the connecting portion 1024 is greater than the thickness of the sidewall of the second device 103.
[0050] In some embodiments, the shape of the connecting portion 1024 may be a cuboid, a cylinder, or other shapes, and this application is not limited thereto.
[0051] In some embodiments, such as Figure 2 As shown, the fixing part 1025 is elongated and has rounded ends. However, this application is not limited to this; the ends of the fixing part 1025 can also be square or other shapes. Therefore, by making the ends of the fixing part round, the engagement surface can be increased, reducing the risk of fixing failure.
[0052] Figure 4 This is a schematic diagram of the fixing part of the fixing device according to an embodiment of this application extending into the second device, as shown. Figure 4 As shown, the side wall of the second device 103 adjacent to the first device 101 has a snap-fit mounting hole 1031 that is adapted to the shape of the fixing part 1025. The snap-fit mounting hole 1031 is slightly larger than the fixing part 1025 to ensure that the fixing part 1025 can pass through the snap-fit mounting hole 1031 and enter the second device 103. Figure 4 Two snap-fit mounting holes 1031 are illustrated, with the upper snap-fit mounting hole 1031 extending into the fixing part 1025. (See example...) Figure 4 As shown, the fixing part 1025 has been rotated at a certain angle, so it cannot be disengaged from the snap-fit mounting hole 1031.
[0053] Figure 5 This is a schematic diagram of a fixing device fixing a first device and a second device according to an embodiment of this application, as shown below. Figure 5 As shown, when the first device 101 and the second device 103 are arranged adjacent to each other, the connecting part 1024 of the fixing device 102 ( Figure 4(Not shown) The fixing part 1025 of the fixing device 102 extends into the interior of the second device 103 through the snap-fit mounting hole 1031 of the second device 103, passing through the side wall of the second device 103. Thus, after being rotated, the fixing part of the fixing device can engage with the side wall of the second device, thereby fixing the device.
[0054] In some embodiments, in the parallel direction of the first device 101 and the second device 103, the thickness of the snap-fit mounting hole 1031 is less than the length of the connecting portion 1024, thereby ensuring that the fixing portion 1025 connected to the connecting portion 1024 can extend into the second device 103, thereby achieving the fixing of the device.
[0055] Figure 6 This is a partial schematic diagram of the first device according to an embodiment of this application, as shown below. Figure 6 As shown, the first device 101 also includes a first opening 1011 and a second opening 1013, wherein the first opening 1011 is located on the upper side of the first device 101, and the second opening 1013 is located on the side of the first device 101 adjacent to the second device 103 and communicates with the first opening 1011.
[0056] In some embodiments, the fixing device 102 is mounted on the first device 101 through a first opening 1011 and a second opening 1013. That is, the pivot portion 1023 and the deformation portion 1022 of the fixing device 102 are mounted in the first device 101 through the first opening 1011, and the connecting portion 1024 extends the fixing portion 1025 out of the first device 101 through the second opening 1013.
[0057] In some embodiments, the fixing device 102 fixed in the first device 101 can be removed through the first opening 1011 and the second opening 1013.
[0058] This improves the ease of disassembling the fixing device. Furthermore, when the fixing device fails and the equipment cannot be secured, the detachable fixing device allows for timely replacement of the damaged device, reducing operating costs.
[0059] In some embodiments, such as Figure 2 As shown, the fixing device 102 also includes a locking part 1026, wherein the locking part 1026 is located on the side of the deformable part 1022 near the operating part 1021 and protrudes in a direction away from the rotating shaft part 1023. When the operating part 1021 is pressed, the deformable part 1022 deforms, and the locking part 1026 enters the interior of the first device 101 through the first opening 1011, and the locking part 1026 engages with the upper wall of the interior of the first device 101; when the operating part 1021 is pushed upward, the deformable part 1022 deforms, and the locking part 1026 leaves the first device 101 through the first opening 1011.
[0060] Therefore, by engaging with the upper wall inside the first device, the locking part prevents the operating part from automatically lifting up after being pressed, further reducing the risk of fixing failure.
[0061] In some embodiments, the shape of the engaging portion 1026 may be trapezoidal or square, and this application is not limited thereto.
[0062] In some embodiments, such as Figure 2 As shown, the fixing device 102 also includes a first limiting portion 1027, wherein the first limiting portion 1027 is located on the side of the deformable portion 1022 near the operating portion 1021, and protrudes in the direction toward the second device 103. Correspondingly, as... Figure 3 As shown, a limiting groove 1014 is provided on the side wall adjacent to the second device 103 inside the first device 101. A first limiting part 1027 is located in the limiting groove 1014. Under the restriction of the limiting groove 1014, the movable range of the first limiting part 1027 is limited. That is, the limiting groove 1014 restricts the movement of the fixing device 102 in the first device 101, and avoids the fixing device 102 from being unable to be fixed in the first device 101 when the operating part 1021 is not pressed.
[0063] In some embodiments, the shape of the first limiting portion 1027 may be trapezoidal or square, and this application is not limited thereto.
[0064] In some embodiments, the shape of the limiting groove 1014 may be square or other shapes, and this application is not limited thereto.
[0065] In some embodiments, such as Figure 2 As shown, the fixing device 102 also includes a second limiting part 1028, wherein the second limiting part 1028 is located on the side of the rotating shaft part 1023 away from the fixing part 1025, and protrudes in the opposite direction to the second device 103. Furthermore, after the fixing device 102 is installed, the second limiting part 1028 engages with the upper wall inside the first device 101, thereby further restricting the movement of the fixing device 102 within the first device 101 and ensuring that the fixing device 102 can be fixed within the first device 101.
[0066] In some embodiments, the shape of the second limiting portion 1028 may be trapezoidal or square, and this application is not limited thereto.
[0067] In some embodiments, based on the need to save costs, a recessed or hollowed-out design can be made at an appropriate position on the pivot portion. For example, a groove can be designed on the other side of the pivot portion 1023 corresponding to the second limiting portion 1028, and / or on the other side of the pivot portion 1023 corresponding to the connecting portion 1024, to ensure that the cost is further reduced while the function of the fixing device 102 is complete.

[0069] 701, The fixing part of the fixing device installed on the first device is inserted into the second device through the snap-fit mounting hole of the second device;
[0070] 702, the operating part of the pressing and fixing device;
[0071] 703, the deformation part deforms, causing the rotating shaft part to rotate, which in turn causes the fixing part to rotate through the connecting part, so that the fixing part engages with the side wall of the second device, wherein the side wall of the second device is the internal side wall adjacent to the first device;
[0072] 704, Operating part of the upward-pushing fixing device;
[0073] 705, the deformation part deforms, causing the rotating shaft part to rotate, which in turn causes the fixing part to rotate through the connecting part, so that the fixing part does not engage with the side wall of the second device;
[0074] 706, The fixing part of the fixing device inside the second device is removed through the snap-fit mounting hole of the second device.

[0076] In this embodiment, the fixing part of the fixing device installed on the first device is inserted into the second device through the snap-fit mounting hole. By operating the operating part, the rotating shaft is rotated, thereby driving the fixing part inside the second device to rotate, so as to fix the two devices together or to release them. Thus, a simple structure can be used to fix the device, while improving operational convenience and the user experience.
[0077] In some embodiments, the fixing device is installed or removed through a first opening and a second opening on the first device. The first opening is located on the upper side of the first device, and the second opening is located on the side of the first device adjacent to the second device and communicates with the first opening. This improves the ease of disassembling the fixing device. Furthermore, when the fixing device is damaged and the device cannot be secured, the detachable fixing device allows for timely replacement of the damaged device, reducing operating costs.
