[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0026] The following describes an embodiment of the utility model based on its overall structure.

[0027] A protective shell for a computer motherboard, such as Figure 1-5 As shown, it includes a protective shell body 100, a placement plate 110 is slidably connected between the inner walls of the protective shell body 100, and a clamping assembly 200 is provided above the placement plate 110;

[0028] The clamping assembly 200 includes a fixed plate 210, and the protective shell body 100 located above the placement plate 110 is fixedly connected to the fixed plate 210 on all sides. The bottom of the fixed plate 210 is slidably connected to a second slider 220, and both sides of the second slider 220 are connected to a first rotating shaft 230. A support rod 240 is sleeved on the outside of the first rotating shaft 230, and the other end of the support rod 240 is rotatably connected to both sides of the placement plate 110 through a second rotating shaft 250.

[0029] The main board is placed on the placement plate 110, and then the placement plate 110 is driven downward by pressing the main board. The placement plate 110 drives the limit block 150 fixedly connected to the end of the connecting rod 120 to move to the inside of the fixed frame 160, and then the limit block 150 squeezes the inclined surface of the limit rod 170 to make the two limit rods 170 move to the outside of the fixed frame 160, and then the limit block 150 moves to the bottom of the limit rod 170 and is clamped. At the same time, the bottom end of the support rod 240 is driven downward by the placement plate 110, and then the second slider 220 is hinged between the support rod 240 and the second slider 220 to move to the right, and then the clamping block 270 fixedly connected to the connecting plate 260 is driven by two groups of second sliders 220 to clamp and fix the main board in the middle.

[0030] By providing a clamping assembly 200 inside the protective shell body 100, and by providing four groups of fixing plates 210 on the inner wall of the protective shell body 100 above the placement plate 110, the fixing plates 210 will drive the placement plate 110 below them to move downward after being squeezed by the mainboard, and when the placement plate 110 moves downward, the second rotating shafts 250 around it will drive the support rod 240 to move via the first rotating shaft 230, and when the support rod 240 moves, it will drive the first slider 140 to move forward, and the first sliders 140 around will also drive the clamping blocks 270 connected to the front of the first slider 140 through the connecting rod 120 to gather towards the middle, thereby clamping the mainboard to prevent the mainboard from being damaged due to being hit and falling during transportation.

[0031] Please refer to Figure 2 A connecting plate 260 is fixedly connected to the front of the second sliding block 220 , and a clamping block 270 is fixedly connected to the front of the connecting plate 260 .

[0032] The clamping blocks 270 fixedly connected to the connecting plates 260 are driven by the two sets of second sliding blocks 220 to clamp and fix the middle main board, and then the main board is clamped and fixed for transportation.

[0033] Please refer to Figure 2 A rubber pad 271 is provided on the front surface of the clamping block 270 , and springs 280 are fixedly connected to the four corners of the bottom of the placement plate 110 .

[0034] The rubber pad 271 increases the friction between the clamping block 270 and the main board, making it difficult for the main board to fall off. The elastic force of the spring 280 can make the placement plate 110 move up and down.

[0035] Please refer to Figure 3 A connecting rod 120 is fixedly connected to the center of the bottom of the placement plate 110 , and a fixing block 130 is fixedly connected to the outer wall of the connecting rod 120 .

[0036] The placement plate 110 drives the limit block 150 fixedly connected to the end of the connecting rod 120 to move into the interior of the fixed frame 160, and at the same time drives the bottom end of the support rod 240 to move downward through the placement plate 110 to clamp the mainboard.

[0037] Please refer to Figure 3 A return spring 131 is fixedly connected to the bottom of the fixed block 130 , and the other end of the return spring 131 is connected to a first sliding block 140 slidably connected to the outer wall of the connecting rod 120 .

[0038] The reset spring 131 is used for moving and resetting the first slider 140 . The first slider 140 is driven by the connecting rod 120 to move upward and is squeezed by the limiting rod 170 , so that the first slider 140 slides downward on the connecting rod 120 and fits against the outer wall of the limiting block 150 .

[0039] Please refer to Figure 5 The end of the connecting rod 120 is fixedly connected to a limiting block 150 , and a fixing frame 160 is fixedly connected to the bottom of the protective shell 100 below the limiting block 150 .

[0040] The placement plate 110 drives the limiting block 150 fixedly connected to the end of the connecting rod 120 to move to the inside of the fixed frame 160 , and then the limiting block 150 squeezes the inclined surface of the limiting rod 170 to make the two limiting rods 170 move to the outside of the fixed frame 160 .

[0041] Please refer to Figure 5 , limiting rods 170 penetrating into the interior are provided on both sides of the fixing frame 160 , and limiting springs 171 are sleeved on the outside of the limiting rods 170 .

[0042] The limiting block 150 presses the inclined surface of the limiting rod 170 to make the two limiting rods 170 move to the outside of the fixing frame 160, and then the limiting block 150 moves to the bottom of the limiting rod 170 and is clamped.

[0043] When in use, when the mainboard needs to be transported, the mainboard is first placed on the placement plate 110, and then the placement plate 110 is driven downward by pressing the mainboard, and the placement plate 110 drives the limit block 150 fixedly connected to the end of the connecting rod 120 to move to the inside of the fixed frame 160, and then the limit block 150 squeezes the inclined surface of the limit rod 170 to make the two limit rods 170 move toward the outside of the fixed frame 160, so that the limit block 150 moves to the bottom of the limit rod 170 and is clamped. At the same time, the bottom end of the support rod 240 is driven downward by the placement plate 110, and then the second slide block 220 is hinged between the support rod 240 and the second slide block 220 to move to the right, and then the clamping block 270 fixedly connected to the connecting plate 260 is driven by the two groups of second slide blocks 220 to clamp the mainboard in the middle. The first slider 140 is then driven by the connecting rod 120 to move to the bottom of the limit rod 170. At this time, the placement plate 110 is moved upward by the elastic force of the spring 280, and then the first slider 140 is driven by the connecting rod 120 to be squeezed by the limit rod 170 during the upward movement, so that the first slider 140 slides downward on the connecting rod 120 and fits the outer wall of the limit block 150. Finally, the limit rod 170 is squeezed by the arc-shaped outer wall of the first slider 140, so that the first slider 140 and the limit block 150 move together to the top of the limit rod 170 and are released from the limit, so that the clamping block 270 moves backward and no longer clamps the middle mainboard.
