Detailed Embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Refer to Figures 1-4, A fixture and an automatic opening and closing cover device for the fixture, including a base 1, on which a bidirectional threaded rod 2 is rotatably installed. One end of the bidirectional threaded rod 2 passes through the base 1 and is connected to a servo motor 3. Two clamping blocks 4 are threadedly connected to the bidirectional threaded rod 2. An electronic product 5 is placed between the two clamping blocks 4. Two connecting plates 6 are oppositely installed on the base 1. The same pressing plate 7 is rotatably installed on the two connecting plates 6. A connecting rod 8 is installed at the middle position on one side of the pressing plate 7. The end of the connecting rod 8 away from the pressing plate 7 is rotatably connected to an L-shaped connecting block 9. The L-shaped connecting block 9 is slidably connected to one of the connecting plates 6. A hydraulic rod 10 is installed on the side wall of this connecting plate 6. The output end of the hydraulic rod 10 is connected to the L-shaped connecting block 9.

[0022] When using this device, first place the electronic product 5 between the two clamping blocks 4 on the base 1. Then start the servo motor 3. The servo motor 3 drives the bidirectional threaded rod 2 to rotate, so that the two clamping blocks 4 threadedly connected to the bidirectional threaded rod 2 approach each other, thus completing the fixation of the electronic product 5. Then start the hydraulic rod 10. The output end of the hydraulic rod 10 moves towards its own body direction, thereby pulling the L-shaped connecting block 9 to move in the same direction, and further driving the connecting rod 8 to move on the L-shaped connecting block 9 and driving the pressing plate 7 to rotate. When the L-shaped connecting block 9 moves to the center position of the connecting plate 6, the connecting rod 8 drives the pressing plate 7 to rotate to a state parallel to the electronic product 5 and contact the electronic product 5, thereby further fixing the electronic product 5. When the pressing plate 7 needs to be opened, control the output shaft of the hydraulic rod 10 to move towards the end away from its own body, thereby indirectly driving the pressing plate 7 to rotate in the opposite direction, and then driving the pressing plate 7 to open. This device has a simple structure, can effectively achieve the opening and closing actions of the pressing plate 7, and is beneficial to reducing production costs.

[0023] Specifically, in this embodiment, a device groove 11 is opened on the base 1. The bidirectional threaded rod 2 is inside the device groove 11. The lower parts of the two clamping blocks 4 are adapted to the device groove 11, so that the bidirectional threaded rod 2 can be rotatably installed on the base 1 through the device groove 11. At the same time, the device groove 11 can limit the clamping blocks 4 through its adaptability to the clamping blocks 4, so that the clamping blocks 4 can only move along the direction of the device groove 11.

[0024] Specifically, in this embodiment, first connecting shafts 12 are installed at both ends of the pressing plate 7. Connecting holes 13 are opened on the two connecting plates 6. The two connecting holes 13 and the two first connecting shafts 12 are on the same horizontal line, so that the two first connecting shafts 12 can be rotatably connected to the corresponding connecting holes 13, so that the pressing plate 7 is rotatably connected to the two connecting plates 6, thus facilitating the opening and closing of the pressing plate 7 by rotating the pressing plate 7.

[0025] Specifically, in this embodiment, first connection grooves 14 are formed on both of the two connection plates 6. Second connection shafts 20 are installed at both ends of the pressing plate 7. The first connection grooves 14 are adapted to the second connection shafts 20, so that the two second connection shafts 20 can be inserted into the corresponding first connection grooves 14, thereby achieving complete contact between the pressing plate 7 and the electronic product 5 by the way that the two second connection shafts 20 fall into the first connection grooves 14.

[0026] Specifically, in this embodiment, a sliding groove 15 is formed on the L-shaped connection block 9. The sliding groove 15 is adapted to one end of the connecting rod 8 close to the L-shaped connection block 9, so that one end of the connecting rod 8 close to the L-shaped connection block 9 can be slidably connected to the sliding groove 15, so that when the L-shaped connection block 9 moves, the pressing plate 7 can be driven to move synchronously through the connecting rod 8, thereby realizing the rotation of the pressing plate 7.

[0027] Specifically, in this embodiment, a second connection groove 16 is formed at the top of the connection plate 6 close to the L-shaped connection block 9. A limiting block 17 is installed at the bottom of the L-shaped connection block 9. The limiting block 17 is slidably connected in the second connection groove 16, so that the L-shaped connection block 9 can be slidably connected to the corresponding connection plate 6 through the adaptability between the limiting block 17 and the second connection groove 16, thereby restricting the moving direction of the L-shaped connection block 9 through the second connection groove 16 and avoiding the situation of deviation during the movement of the L-shaped connection block 9.

[0028] Specifically, in this embodiment, a notch 18 is formed on the pressing plate 7. The notch 18 is located at the center of the pressing plate 7. Two elastic sheets 19 are installed on one side wall of the pressing plate 7 close to the electronic product 5, so that the position to be detected on the electronic product 5 can be exposed outside the pressing plate 7 through the notch 18. At the same time, the friction between the electronic product 5 and the pressing plate 7 is increased through the arrangement of the elastic sheets 19, thereby improving the fixing effect of the pressing plate 7 on the electronic product 5.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
