Please refer to Figures 1 to 5. The fixing device 100 of this embodiment is suitable for being arranged on the plate 10 to fix the object 20 detachably arranged on the plate 10. In this embodiment, the plate 10 includes a nut seat 14 (Figure 5) arranged thereon. The fixing device 100 is detachably arranged on the nut seat 14 of the plate 10.

Specifically, the board 10 is, for example, a circuit board, and the object 20 is, for example, an M.2 expansion card. The board 10 further includes a slot 18 (FIG. 1) disposed thereon, and the slot 18 is, for example, an M.2 slot, but the types of the board 10, the object 20, and the slot 18 are not limited thereto. One end of the object 20 (for example, an M.2 expansion card) is inserted into the slot 18, and the other end of the object 20 (for example, an M.2 expansion card) can be fixed by the fixing device 100, so that the object 20 (for example, an M.2 expansion card) can be stably fixed to the board 10 (for example, a circuit board).

The fixing device 100 of this embodiment can be easily and conveniently fixed to the nut seat 14 (Figure 4) on the plate 10, and can be quickly fixed or released by hand operation. The fixing device 100 and related components will be described below.

As shown in FIG5 , the fixing device 100 includes a base 105, a buckle assembly 140 and an elastic member 150. The base 105 includes a main body 110 and a fixing portion 120 extending from a bottom surface 112 of the main body 110. The main body 110 includes a bearing surface 111 located on the upper surface.

The buckle assembly 140 is movably disposed on the base 105, and the buckle assembly 140 includes a moving portion 141 and a locking portion 144. In this embodiment, the moving portion 141 and the locking portion 144 are integrated, but the moving portion 141 and the locking portion 144 are not limited to this. In this embodiment, the locking portion 144 is located above the bearing surface 111, and the object 20 can be located in the space between the locking portion 144 and the bearing surface 111.

The fixing device 100 further includes a stopper 160, which is disposed on the main body 110. The fixing device 100 further includes a screw 170, the stopper 160 includes a through hole 162, the main body 110 includes a first screw hole 117, the screw 170 passes through the through hole 162 of the stopper 160 and is screwed to the first screw hole 117 of the main body 110, and the nut 117 of the screw 170 presses the stopper 160 to fix the stopper 160 to the main body 110.

The stopper 160 and the main body 110 form a track together, and the buckle assembly 140 slides in the track. In other words, the buckle assembly 140 can be moved between the stopper 160 and the main body 110.

The elastic member 150 is disposed between the main body 110 and the buckle assembly 140. Specifically, the main body 110 includes a groove 119 recessed in the upper surface and a stopper 118, and the buckle assembly 140 includes a hole 145 located between the moving part 141 and the abutting part 144. The stopper 118 is located in the hole 145, and the stopper 118 protrudes from the bearing surface 111 and is close to the moving part 141.

The elastic member 150 abuts between the stopper 118 and the wall of the hole 145 near the abutting portion 144, and a portion of the elastic member 150 is located in the groove 119. Therefore, as shown in FIG. 3B , when the buckle assembly 140 moves rightward relative to the main body 110, the elastic member 150 will be compressed.

As shown in FIG. 2A and FIG. 2B , the object 20 is suitable for being sandwiched between the bearing surface 111 and the abutting portion 144. When the moving portion 141 is moved as shown in FIG. 3A and FIG. 3B , the buckle assembly 140 moves so that the abutting portion 144 is away from the bearing surface 111, and the object 20 is released. At this time, the elastic member 150 is compressed. When the moving portion 141 is released, the elastic member 150 resets the buckle assembly 140. Therefore, the fixing device 100 of this embodiment can be operated by hand to achieve the effect of quickly fixing or releasing the object 20.

It is worth mentioning that in one embodiment, the fixing device 100 may not have an elastic member 150 additional to the buckle assembly 140, or the buckle assembly 140 may be elastic, and when the moving part 141 is moved, the buckle assembly 140 is deformed, and when the moving part 141 is released, the buckle assembly 140 is restored and reset.

In addition, as shown in FIG. 5 , in this embodiment, the fixing portion 120 of the fixing device 100 is suitable for fixing to the nut seat 14 on the plate 10 ( FIG. 1 ). The nut seat 14 includes a second screw hole 15 and a positioning groove 16, and the base 105 includes a positioning portion 130 extending from the bottom surface 112 of the main body 110. The positioning portion 130 is, for example, a stud, and can be screwed to the second screw hole 15 of the nut seat 14, but the method of fixing the positioning portion 130 to the plate 10 is not limited to this.

The positioning portion 130 includes a stop surface 131 perpendicular to the bottom surface 112 and a first inclined surface 132 inclined relative to the bottom surface 112, and the positioning groove 16 includes a second inclined surface 17 corresponding to the first inclined surface 132. In this embodiment, when the fixing portion 135 is screwed to the screw hole 15, the main body 110 will gradually approach the nut seat 14.

In this embodiment, the nut seat 14 is positioned on the plate 10 in a specific direction, the screw hole 15 of the nut seat 14 has a predetermined internal thread starting point, and the fixing portion 135 also has a predetermined number of external thread turns. Therefore, when the fixing portion 135 is completely screwed into the screw hole 15 of the nut seat 14, the positioning portion 130 will be located in the positioning groove 16. In this embodiment, the height H1 (Figure 6B) of the positioning portion 130 protruding from the bottom surface 112 is less than or equal to the pitch H2 (Figure 6B) of the fixing portion 135 to avoid interference between the positioning portion 130 and the plate 10.

When the positioning portion 130 is located in the positioning groove 16, the first inclined surface 132 of the positioning portion 130 faces the second inclined surface 17 of the positioning groove 16. The stop surface 131 of the positioning portion 130 is limited by the vertical wall of the positioning groove 16, so that the fixing portion 135 cannot continue to rotate downward, and the main body 110 can be accurately positioned so that the main body 110 can face a specific direction when fixed on the plate 10. Such a design allows the subsequent fixing device 100 to face the object 20 in a specific direction to fix the object 20 well.

In addition, when the fixing portion 135 is to be separated from the nut seat 14, since the first inclined surface 132 faces the second inclined surface 17, as long as the base 105 is reversed, the first inclined surface 132 will follow the second inclined surface 17, so that the fixing portion 135 can smoothly rotate upward.

In addition, the main body 110 further includes a first portion 114, a second portion 115, and a hollow area 116 located between the first portion 114 and the second portion 115. The fixing portion 120 protrudes from the first portion 114, the positioning portion 130 protrudes from the second portion 115, and the thickness of the second portion 115 is less than the thickness of the first portion 114. The hollow area 116 can provide a retracted space for the first portion 114, so that the first portion 114 can be deformed more easily, and the positioning portion 130 located on the first portion 114 can also move its position more flexibly when entering or leaving the positioning groove 16. Therefore, the fixing device 100 can be easily disassembled and assembled to the nut seat 14 of the plate 10.

The following describes the main differences between the fixing device 100a of another embodiment and the fixing device 100 of the previous embodiment, and the remaining same or similar components are not described in detail.

FIG6A is a partially enlarged schematic diagram of an object on a plate being fixed by a fixing device of another embodiment of the present invention. FIG6B is a schematic diagram of the plate and the object with FIG6A hidden. FIG7A is a schematic diagram of the moving part of the fixing device of FIG6A after movement. FIG7B is a schematic diagram of the plate and the object with FIG7A hidden. FIG8 is a schematic diagram of the stopper of the fixing device of FIG6A. FIG9A and FIG9B are schematic diagrams of the fixing device of FIG6A from different viewing angles after the stopper is hidden.

Please refer to Figures 6A to 9B. The stopper 160a of the fixing device 100a of this embodiment is disposed on the main body 110, and the stopper 160a and the main body 110 together form a space. As shown in Figure 8, the stopper 160a is formed with a track 164 extending along the first axial direction A1, and the moving part 141a passes through the track 164 and protrudes above the stopper 160a.

As shown in FIG9A and FIG9B , in this embodiment, the moving portion 141a and the abutting portion 144 of the buckle assembly 140a are two separate parts. As shown in FIG7A and FIG7B , in this embodiment, when the moving portion 141a is pressed down to move the moving portion 141a relative to the stopper 160a along the first axis A1, the abutting portion 144 moves along the second axis A2. That is, the abutting portion 144 is suitable for being movably arranged in the space between the stopper 160a and the main body 110 along the second axis A2, and the moving portion 141a is located in the track 164 and is suitable for sliding along the first axis A1. The movement direction of the moving portion 141a of the fixing device 100a of this embodiment is different from the movement direction of the abutting portion 144.

Specifically, the abutment portion 144 includes a connected receiving groove 146 and an inclined groove 147. The moving portion 141a is located in the receiving groove 146 and includes a slider 142 slidably disposed in the inclined groove 147. The elastic member 150 is located in the receiving groove 146 and between the main body 110 and the moving portion 141.

Since the moving part 141a is restricted by the track 164 and can only move along the first axis A1, when the moving part 141a is pressed down and slides along the first axis A1, the slider 142 of the moving part 141a pushes against the wall of the inclined groove 147 and drives the abutting part 144 to move along the second axis A2, so that the abutting part 144 moves away from the bearing surface 111 and releases the object 20. At this time, the elastic member 150 is compressed. When the moving part 141a is released, the elastic member 150 resets the moving part 141a and drives the abutting part 144 to reset. Therefore, the fixing device 100a of this embodiment can be operated by hand to achieve the effect of quickly fixing or releasing the object 20.

In summary, the main body of the base of the fixing device of the present invention includes a bearing surface, and the fixing part of the base is suitable for fixing to the board. The buckle assembly is movably arranged on the base, and includes a moving part and a clamping part. The clamping part is located above the bearing surface. The elastic member is arranged between the main body and the buckle assembly. The object is suitable for being clamped between the bearing surface and the clamping part. When the moving part is moved, the buckle assembly moves to make the clamping part away from the bearing surface, and the object is released, and the elastic member is compressed. When the moving part is released, the elastic member resets the buckle assembly. In this way, the fixing device of the present invention can achieve the effect of quickly disassembling and assembling the object arranged on the board by hand operation without tools.
