[0004] The purpose of this utility model is to solve the problem that in the existing technology, computer motherboards are often installed using screws, but if the screws are lost, the computer motherboard cannot be installed stably, which greatly reduces the installation efficiency. Therefore, a computer motherboard mounting and fixing device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A computer motherboard mounting and fixing device includes a base;

[0007] Two support plates are symmetrically and fixedly connected to the top of the base;

[0008] A contact frame, which is slidably connected to two support plates on one side that are close to each other;

[0009] Two positioning plates are slidably connected to the top of adjacent support plates;

[0010] The installation mechanism includes two push plates, two sliding plates, and two fixed plates. The push plates are rotatably connected to the bottom of adjacent positioning plates. The sides of the two sliding plates that are close to each other are slidably connected to the sides of the two support plates that are far apart from each other. The fixed plates are slidably connected to the front side of the sliding plates, and the sides of the two fixed plates that are close to each other are in active contact with the sides of the two support plates that are far apart from each other.

[0011] As a preferred embodiment of this utility model, a pull plate is slidably connected to the bottom of the base, and a drive plate is fixedly connected to both the left and right sides of the pull plate.

[0012] As a preferred embodiment of this utility model, vertical grooves are provided on the sides of the two support plates that are close to each other. The left and right sides of the contact frame extend into the vertical grooves and are slidably connected to the inner wall of the vertical grooves. Four No. 1 springs are fixedly connected to the bottom of the contact frame.

[0013] As a preferred embodiment of this utility model, auxiliary plates are fixedly connected to the sides of the two positioning plates that are far apart from each other, and rotating plates are rotatably connected to the bottom of the auxiliary plates. The sides of the two rotating plates that are close to each other are rotatably connected to the top of the adjacent driving plate.

[0014] As a preferred embodiment of this utility model, a second spring is fixedly connected to the side of the two fixed plates that are close to each other, and the end of the two second springs that are close to each other is fixedly connected to the side of the two sliding plates that are far apart from each other.

[0015] As a preferred embodiment of this utility model, auxiliary rings are fixedly connected to both the front and rear sides of the base, and the number of auxiliary rings is four.

[0016] Beneficial effects:

[0017] 1. By placing the main board on top of the contact frame, pressing the main board lowers it, and the main board can simultaneously press the contact frame lower, while pulling the pull plate backward. When the pull plate moves, it can simultaneously drive the two drive plates to move backward. As the drive plates move, they can simultaneously pull the rotating plate, thereby pulling the two auxiliary plates closer to each other through the rotating plate.

[0018] 2. When the auxiliary plate moves, it can simultaneously control the two positioning plates to move closer to each other, thereby guiding the positioning plates to move above the contact frame and the main board. At the same time, as the positioning plates move, they can push the push plate to move. As the push plate moves, it can simultaneously drag the sliding plate forward. At this time, the movement of the sliding plate can simultaneously drive the fixed plate to move. When the fixed plate and the left and right sides of the support plate are no longer in contact, the second spring is initially in a stretched state, which can control the two fixed plates to move closer to each other, thereby contacting the front side of the support plate. At this time, the entire device is locked.

[0019] 3. Simultaneously release the pressure on the contact frame. The No. 1 spring assists the contact frame in pushing the main board and the positioning plate into close contact. The pressure enables the main board to be installed quickly, facilitating operation.

[0020] In this invention: by placing the main board on top of the contact frame and pressing it down, the pull plate is moved, and the pull plate assists the positioning plate to move above the main board. At the same time, the fixing plate locks the entire device. The first spring is in close contact with the positioning plate through the contact frame guide plate, and the main board is quickly installed by pressure, avoiding the use of screws and making the work more convenient.

[0027] Example

[0028] Reference Figures 1-4 A computer motherboard mounting and fixing device, including a base 1;

[0029] Two support plates 2 are symmetrically and fixedly connected to the top of the base 1;

[0030] Contact frame 3 is slidably connected to the two support plates 2 on one side that are close to each other;

[0031] Two positioning plates 8 are slidably connected to the top of adjacent support plates 2;

[0032] The installation mechanism includes two push plates 10, two sliding plates 11 and two fixed plates 12. The push plates 10 are rotatably connected to the bottom of the adjacent positioning plates 8. The sides of the two sliding plates 11 that are close to each other are slidably connected to the sides of the two support plates 2 that are far apart from each other. The fixed plates 12 are slidably connected to the front side of the sliding plates 11, and the sides of the two fixed plates 12 that are close to each other are in active contact with the sides of the two support plates 2 that are far apart from each other.

[0033] With the above structure: by setting up the support plate 2, the support plate 2 restricts the longitudinal movement of the contact frame 3, which facilitates the descent of the main board; by setting up the positioning plate 8, the positioning plate 8 contacts the main board, and at the same time the contact frame 3 provides support, which facilitates installation.

[0034] As a preferred embodiment of this utility model, a pull plate 5 is slidably connected to the bottom of the base 1, and a driving plate 6 is fixedly connected to both the left and right sides of the pull plate 5. When the pull plate 5 moves, the pull plate 5 can simultaneously pull the driving plate 6 to move laterally.

[0035] As a preferred embodiment of this utility model, vertical grooves are provided on the sides of the two support plates 2 that are close to each other. The left and right sides of the contact frame 3 extend into the vertical grooves and slide to connect with the inner wall of the vertical grooves. Four No. 1 springs 4 are fixedly connected to the bottom of the contact frame 3. By setting the vertical grooves, the vertical grooves restrict the longitudinal movement of the contact frame 3, while the No. 1 springs 4 assist the contact frame 3 to move upward.

[0036] As a preferred embodiment of this utility model, auxiliary plates 9 are fixedly connected to the sides of the two positioning plates 8 that are far apart from each other. Rotating plates 7 are rotatably connected to the bottom of the auxiliary plates 9. The sides of the two rotating plates 7 that are close to each other are rotatably connected to the top of the adjacent driving plate 6. When the driving plate 6 moves, the driving plate 6 pulls the rotating plate 7 to move, thereby pulling the auxiliary plates 9 closer to each other through the rotating plate 7, and thus controlling the positioning plates 8 to move closer to each other.

[0037] As a preferred embodiment of this utility model, a second spring 13 is fixedly connected to the side of the two fixed plates 12 that are close to each other, and the end of the two second springs 13 that are close to each other is fixedly connected to the side of the two sliding plates 11 that are far apart from each other. By setting the second spring 13, the second spring 13 is initially in a stretched state, which can pull the two fixed plates 12 to move.

[0038] As a preferred embodiment of this utility model, auxiliary rings are fixedly connected to both the front and rear sides of the base 1, and the number of auxiliary rings is four. By setting the auxiliary rings, the auxiliary rings are used to connect with the inner wall of the main unit.

[0039] It should be noted that the specific model of base 1 and contact frame 3 to be used shall be selected by those skilled in the art, and the above-mentioned base 1 and contact frame 3 are existing technologies, which will not be elaborated in this solution.

[0040] The working principle of this utility model is as follows: In actual operation, the main board is placed on top of the contact frame 3. Pressing the main board lowers it, and the main board simultaneously presses the contact frame 3 downwards, pulling the pull plate 5 backwards. As the pull plate 5 moves, it simultaneously drives two driving plates 6 backwards. With the movement of the driving plates 6, the driving plates 6 simultaneously pull the rotating plate 7, causing the two auxiliary plates 9 to move closer together. As the auxiliary plates 9 move, they simultaneously control the two positioning plates 8 to move closer together, thus guiding the positioning plates 8 to move above the contact frame 3 and the main board. The movement of the positioning plate 8 can push the push plate 10 to move. As the push plate 10 moves, it can simultaneously drag the sliding plate 11 forward. At this time, the movement of the sliding plate 11 can simultaneously drive the fixed plate 12 to move. When the fixed plate 12 disengages from the left and right sides of the support plate 2, the second spring 13 is initially in a stretched state, which can control the two fixed plates 12 to move closer to each other, thereby making contact with the front side of the support plate 2. At this time, the entire device is locked, and the pressure on the contact frame 3 is released. The first spring 4 assists the contact frame 3 in pushing the main board to make tight contact with the positioning plate 8. The pressure enables the quick installation of the main board, which is convenient for work.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
