[0018] 1. The present invention has a reasonable structure. When the control knob is turned, the bidirectional screw rod will be driven to rotate synchronously through the control rotating rod, the first bevel gear and the second bevel gear. The rotation of the bidirectional screw rod will drive the two L-shaped protective plates to move toward or away from each other through the moving plate and the connecting rod. When the two L-shaped protective plates are moved toward each other until they are in contact with each other, the gateway device body can be shielded and protected, which can effectively reduce the situation where a large amount of dust is deposited on the gateway device body and the gateway device body is damaged by accidental collision, thereby improving the service life of the gateway device body.

[0019] 2. In the present invention, when the two moving plates move toward each other, the four rope wheels will rotate simultaneously through the connecting pull rope. When the two moving plates move away from each other, the four rope wheels will automatically reverse under the elastic force of the rotary torsion spring. The rotation of the rope wheels will drive the moving piston to move up and down through the vertical screw rod and the vertical screw barrel, thereby reducing or increasing the pressure in the fixed suction cup, and the hollow placement seat will be adsorbed and fixed on the smooth desktop or released, thereby effectively reducing the situation where the gateway device body and the hollow placement seat fall and are damaged due to accidental collision, and the use is stable and reliable;

[0020] 3. In the present invention, when the handle block is pulled, the fixed rod will be moved out of the fixed socket to loosen the control knob. When the handle block is loosened, the elastic force of the reset spring will squeeze the push tab to drive the fixed rod to automatically reset and insert into the fixed socket, so that the control knob is always fixed and cannot be rotated, thereby effectively reducing the possibility of the gateway device body and the hollow placement seat being loosened due to accidentally touching the control knob, and providing better stability during use.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example: Reference Figure 1-Figure 6 A gateway device for computer network engineering shown in the figure comprises a gateway device body 1 and a hollow placement seat 2, on which a connected protection mechanism and an adsorption fixing mechanism are installed;

[0031] The protection mechanism includes two matched L-shaped protection plates 3, and the sides of the two L-shaped protection plates 3 that are away from each other are provided with two horizontal sliding holes, and the four horizontal sliding holes are slidably installed with horizontal sliding rods 4, and one end of the four horizontal sliding rods 4 is fixedly installed with a pressure plate 5 that fits the side of the gateway device body 1, and the four pressure plates 5 are installed with elastic extrusion elements, and the elastic extrusion elements include a compression spring 6 sleeved on the horizontal sliding rod 4, and the two ends of the compression spring 6 are respectively fixedly installed on the sides of the L-shaped protection plate 3 and the pressure plate 5, and the side of the hollow placement seat 2 is provided with a mounting rotation hole, and a control rotating rod 9 is rotatably installed in the mounting rotation hole, and one end of the control rotating rod 9 is connected to a driving component for making the two L-shaped protection plates 3 move toward or away from each other at the same time, and the other end of the control rotating rod 9 is fixedly installed with a control knob 10;

[0032] By means of the above structure and the setting of the protective mechanism, when the control knob 10 is rotated, the control lever 9 will be driven to rotate. The rotation of the control lever 9 will drive the two L-shaped protective plates 3 to move toward or away from each other at the same time through the driving component. When the two L-shaped protective plates 3 are moved toward each other and fit together, the gateway device body 1 can be shielded and protected, which can effectively reduce the occurrence of a large amount of dust deposited on the gateway device body 1 and the situation where the gateway device body 1 is damaged by accidental collision, thereby improving the service life of the gateway device body 1. During this process, the pressure plate 5 will move with the L-shaped protective plate 3. Under the guiding cooperation of the horizontal sliding bar 4 and the elastic force of the compression spring 6, the gateway device body 1 can be squeezed and fixed. When the two L-shaped protective plates 3 are moved away from each other, the gateway device body 1 can be loosened and exposed, so that the gateway device body 1 can be quickly taken out for inspection and maintenance.

[0033] The adsorption and fixing mechanism includes four fixed suction cups 7 evenly fixedly installed on the bottom of the hollow placement seat 2, and mobile pistons 8 are slidably installed in the four fixed suction cups 7. A control component for controlling the simultaneous up and down movement of the four mobile pistons 8 is installed on the hollow placement seat 2, and the driving component is connected to the control component.

[0034] By means of the above structure, through the setting of the adsorption and fixing mechanism, when the driving component is running, the control component will also run at the same time. The operation of the control component will cause the four movable pistons 8 to move up and down at the same time, thereby reducing or increasing the pressure in the fixed suction cup 7, and adsorbing and fixing the hollow placement seat 2 on a smooth desktop or releasing it, thereby effectively reducing the possibility of the gateway device body 1 and the hollow placement seat 2 falling and being damaged due to accidental collision during use, and being stable and reliable during use.

[0035] refer to Figure 3 and Figure 6 As shown, the driving assembly includes a bidirectional screw 11 rotatably mounted on the inner wall of the side of the hollow placement seat 2, two connecting rods 13 are detachably mounted on the sides of the two L-shaped protective plates 3 that are close to each other, two avoidance sliding holes are provided on both sides of the hollow placement seat 2 that are far away from each other, and four connecting rods 13 are respectively slidably mounted in the four avoidance sliding holes, and one end of the two connecting rods 13 located on the same side is commonly fixedly mounted with a moving plate 12, and the two moving plates 12 are both threadedly sleeved on the bidirectional screw 11, and the end of the control rotating rod 9 is installed with a synchronous transmission unit for making the bidirectional screw 11 rotate synchronously, and the moving plate 12 is connected to the control assembly. The advantage of such a setting is that when the control rotating rod 9 rotates, the bidirectional screw 11 will be driven to rotate synchronously through the synchronous transmission unit, and the rotation of the bidirectional screw 11 will drive the two moving plates 12 to move toward or away from each other, and then the two L-shaped protective plates 3 can be driven to move toward or away from each other through the connecting rod 13.

[0036] refer to Figure 3 As shown, the synchronous transmission unit includes a first bevel gear 14 fixedly mounted on the end of the control rotating rod 9, and a second bevel gear 15 meshing with the first bevel gear 14 is fixedly sleeved on the bidirectional screw rod 11. The advantage of this arrangement is that when the control rotating rod 9 rotates, the first bevel gear 14 is driven to rotate, and the rotation of the first bevel gear 14 drives the second bevel gear 15 to rotate together, thereby driving the bidirectional screw rod 11 to rotate synchronously, thereby playing a transmission role.

[0037] refer to Figure 2 , Figure 3 and Figure 6 As shown, a mounting hole is provided at the side of the L-shaped protective plate 3, a fastening bolt 16 is movably installed in the mounting hole, a fastening screw hole is provided at the end of the connecting rod 13, and one end of the fastening bolt 16 is threadedly installed in the fastening screw hole. The advantage of such a setting is that when the fastening bolt 16 is rotated, the L-shaped protective plate 3 can be fixed or loosened under the cooperation of the mounting hole and the fastening screw hole, thereby achieving the purpose of facilitating the disassembly and replacement of the L-shaped protective plate 3.

[0038] refer to Figure 3 and Figure 4As shown, the driving assembly includes four vertical screw barrels 18 fixedly mounted on the tops of the four moving pistons 8 respectively, the bottom inner wall of the hollow placement seat 2 and the tops of the four fixed suction cups 7 are jointly provided with four vertical rotating holes, and vertical screws 17 are rotatably mounted in the four vertical rotating holes, the four vertical screw barrels 18 are respectively threadedly sleeved on the four vertical screws 17, and the tops of the four vertical screws 17 are fixedly mounted with rope winding wheels 19, and the sides of the two moving plates 12 away from each other are fixedly mounted with two connecting ropes 20, and the four connecting ropes 20 are respectively wound and mounted on the four rope winding wheels 19, and the four rope winding wheels 19 are respectively mounted with a torsion rotation unit, and the torsion rotation unit includes a rotary torsion spring 21 sleeved on the vertical screw 17, and the two ends of the rotary torsion spring 21 are respectively fixedly mounted on the bottom inner wall of the hollow placement seat 2 and the bottom of the rope winding wheel 19, and the four vertical screw barrels 18 are respectively mounted with a vertical guide unit. The advantage of such a configuration is that when the two movable plates 12 move toward each other, the four rope winding wheels 19 will be pulled to rotate simultaneously through the connecting pull rope 20. At this time, the rotation of the rope winding wheels 19 will cause the rotary torsion spring 21 to undergo elastic deformation. When the two movable plates 12 move away from each other, the elastic force of the rotary torsion spring 21 will cause the four rope winding wheels 19 to automatically reverse at the same time. The rotation of the rope winding wheels 19 will drive the vertical screw 17 to rotate together. With the cooperation of the vertical guide unit, the rotation of the vertical screw 17 will drive the vertical screw barrel 18 to move up and down, thereby driving the movable piston 8 to move up and down together, thereby adsorbing and fixing the hollow placement seat 2 on the smooth desktop.

[0039] refer to Figure 4 As shown, the vertical guide unit includes two vertical guide rods 22 fixedly mounted on the inner wall of the top of the fixed suction cup 7, and guide blocks are slidably sleeved on the two vertical guide rods 22, and the two guide blocks are fixedly mounted on the outer peripheral side of the vertical screw barrel 18. The advantage of this arrangement is that, through the coordinated arrangement of the vertical guide rods 22 and the guide blocks, the movable piston 8 and the vertical screw barrel 18 can only move vertically up and down, and will not rotate with the vertical screw rod 17, which plays a role of vertical guidance and has good stability.

[0040] refer to Figure 3 and Figure 5As shown, a fixed protrusion 23 is fixedly installed on the side of the hollow placement seat 2, and a rod sliding hole is provided on the side of the fixed protrusion 23, and a fixed rod 24 is slidably installed in the rod sliding hole. A plurality of fixed plug holes are evenly provided on the circumferential side of the control knob 10, and one end of the fixed plug rod 24 extends into one of the fixed plug holes, and a handle block 25 is fixedly installed on the other end of the fixed plug rod 24, and a reset unit is installed on the fixed plug rod 24. The advantage of such a setting is that when the handle block 25 is moved, the fixed plug rod 24 will be driven to move in or out of the fixed hole, and then the control knob 10 can be fixed so that it cannot be rotated or loosened, so that during use, the situation that the gateway device body 1 and the hollow placement seat 2 become loose due to accidentally touching the control knob 10 can be effectively reduced, and the stability during use is better.

[0041] refer to Figure 5 As shown, the reset unit includes a convex piece fixedly sleeved on the fixed plug rod 24, the convex piece is located between the fixed protrusion 23 and the control knob 10, and a reset spring 26 is sleeved on the fixed plug rod 24, and the two ends of the reset spring 26 are respectively fixedly mounted on the fixed protrusion 23 and the side of the convex piece. The advantage of this arrangement is that when the handle block 25 is released, the elastic force of the reset spring 26 will squeeze and push the convex piece to automatically reset, and then the fixed plug rod 24 can be driven to reset and automatically inserted into the fixed plug hole, so that the control knob 10 is automatically fixed and can always remain in a fixed state, which is stable and reliable.

[0042] Working principle of the present invention:

[0043] When in use, the handle block 25 can be pulled first until the fixed plug rod 24 moves out of the fixed plug hole and the control knob 10 is loosened. At this time, the control knob 10 can be rotated. The rotation of the control knob 10 will drive the control rotating rod 9 to rotate. The rotation of the control rotating rod 9 will drive the bidirectional screw rod 11 to rotate synchronously through the first bevel gear 14 and the second bevel gear 15. The rotation of the bidirectional screw rod 11 will drive the two movable plates 12 to move toward or away from each other, and then the two L-shaped protective plates 3 can be driven to move toward or away from each other through the connecting rod 13. When the two L-shaped protective plates 3 move toward each other and fit together, the gateway device body 1 can be shielded and protected. At the same time, the pressure plate 5 will move with the L-shaped protective plate 3. Under the guiding cooperation of the horizontal sliding bar 4 and the elastic force of the compression spring 6, the gateway device body 1 can be squeezed and fixed. In this process , the two movable plates 12 move toward each other, and the four rope wheels 19 rotate simultaneously through the connecting pull rope 20. The rotation of the rope wheels 19 drives the vertical screw 17 to rotate together. Under the cooperation of the vertical guide rod 22 and the guide block, the rotation of the vertical screw 17 drives the vertical screw barrel 18 to move upward, and then drives the movable piston 8 to move upward together, reducing the pressure in the fixed suction cup 7, and adsorbing and fixing the hollow placement seat 2 on the smooth desktop. Then release the handle block 25, and under the elastic force of the reset spring 26, the protruding piece will be squeezed and pushed to automatically reset, and then the fixed plug rod 24 can be driven to reset and automatically insert into the fixed plug hole, so that the control knob 10 is always fixed and cannot be rotated, so as to avoid the situation that the gateway device body 1 and the hollow placement seat 2 are loosened due to accidentally touching the control knob 10 during use;

[0044] When the two L-shaped protective plates 3 are moved away from each other, the gateway device body 1 can be loosened and exposed, so that the gateway device body 1 can be quickly taken out for inspection and maintenance, etc. At the same time, under the elastic force of the rotary torsion spring 21, the four rope winding wheels 19 will automatically reverse, and then the movable piston 8 can be driven to move downward through the vertical screw 17 and the vertical screw barrel 18, thereby increasing the pressure in the fixed suction cup 7 and loosening the hollow placement seat 2 from the smooth table top.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
