[0040] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0041] This embodiment provides a toolbox, such as Figures 1 to 4 As shown, the toolbox includes a toolbox body 1, a fixing base 3, a shielding assembly 7 and a pressing assembly 5. The side of the toolbox body 1 is hingedly connected to a box cover 2, and a box lock is installed between the toolbox body 1 and the box cover 2. The fixing base 3 is fixedly set in the inner cavity of the toolbox body 1, and the fixing base 3 has a groove for placing maintenance equipment. The maintenance equipment is placed in the groove of the fixing base 3. The shielding assembly 7 includes a baffle 701, which is movable along a first direction (X direction in the figure) and is arranged in the inner cavity of the toolbox body 1. The pressing assembly 5 includes a moving rod 503, which is movable along a vertical direction within the toolbox body 1. The moving rod 503 is transmission-connected to the baffle 701. When the box cover 2 is closed on the toolbox body 1, it can drive the moving rod 503 to move so that the baffle 701 closes the interface of the maintenance equipment. It is worth noting that in this embodiment, the maintenance equipment is described by taking a network scanner 4 as an example.

[0042] Through the above technical solution, by using the shielding component 7 in conjunction with the pressing component 5, the interface position of the network scanner 4 can be automatically sealed and protected when the box cover 2 is closed, effectively preventing the interface from being corroded by moisture in the air, and preventing the interface of the network scanner 4 from rusting due to long-term exposure, thereby effectively improving the service life of the network scanner 4.

[0043] In this embodiment, the tool box further includes a linkage structure 6 , which connects the baffle 701 and the moving rod 503 to convert the vertical movement of the moving rod 503 into the horizontal movement of the baffle 701 .

[0044] like Figures 1 to 4As shown, the linkage structure 6 includes a transmission assembly, a movable frame 606 and a connecting rod 607. The movable frame 606 is arranged in the tool box body 1 for movement along the second direction (Y direction in the figure). The two ends of the connecting rod 607 are pivotally connected to the movable frame 606 and the baffle 701 respectively. The first direction and the second direction are arranged at an angle. The transmission assembly is configured to transmit and connect the movable rod 503 and the movable frame 606.

[0045] When the movable rod 503 is pressed by the box cover 2, the transmission assembly drives the movable frame 606 to move, and the force exerted by the connecting rod 607 on the baffle 701 generates a component force in the first direction, thereby driving the baffle 701 to move in the first direction, thereby blocking the interface of the network scanner 4 as shown in the solid line. The movable frame 606 is L-shaped.

[0046] like Figure 4 As shown, the linkage structure 6 also includes a second extrusion plate 605, which is fixedly connected to the movable frame 606. The transmission assembly includes a first extrusion plate 604, a movable block 602 and a guide rod 603. The guide rod 603 is fixedly arranged on the side wall of the inner cavity of the tool box body 1. The guide rod 603 is slidably connected to the movable block 602. The movable block 602 is fixedly connected to the first extrusion plate 604. The movable block 602 is transmission-connected to the movable rod 503. The first extrusion plate 604 includes a driving inclined surface, which slides against the second extrusion plate 605 to drive the second extrusion plate 605 to move in the second direction.

[0047] The guide rod 603 can guide the moving block 602. When the moving rod 503 moves, the first extrusion plate 604 moves with the moving block 602. At this time, the driving inclined surface of the first extrusion plate 604 can drive the second extrusion plate 605 to move along the second direction.

[0048] Furthermore, the transmission assembly further includes a connecting plate 601 , and two ends of the connecting plate 601 are pivotally connected to the moving rod 503 and the moving block 602 respectively.

[0049] In summary, through this technical solution, when the moving block 602 moves, it can push the first extrusion plate 604 to move, thereby squeezing the second extrusion plate 605 through the movement of the first extrusion plate 604, causing the second extrusion plate 605 to move, and then driving the moving frame 606 to move, thereby causing the connecting rod 607 to rotate angularly, thereby driving the shielding component 7 to move.

[0050] like Figure 2 and Figure 3 As shown, in order to balance the force on the baffle 701 when it moves, the toolbox includes two groups of pressing components 5 and two groups of linkage structures 6, and one group of pressing components 5 and one group of linkage structures 6 are located on one side of the network scanner 4, and the other group of pressing components 5 and the other group of linkage structures 6 are located on the other side of the network scanner 4.

[0051] like Figure 3 As shown, the pressing assembly 5 also includes a fixed cylinder 501, a movable piston 502 and a return spring 504. The fixed cylinder 501 is fixedly arranged at the bottom surface of the tool box body 1. The movable piston 502 is slidably connected in the inner cavity of the fixed cylinder 501. One end of the movable rod 503 is fixedly connected to the upper surface of the movable piston 502. The other end of the movable rod 503 passes through the upper wall of the inner cavity of the fixed cylinder 501 and extends outside the wall. The return spring 504 is configured to drive the movable rod 503 to extend out of the fixed cylinder 501.

[0052] When the box cover 2 is opened, the return spring 504 can drive the moving rod 503 to extend out of the fixed cylinder 501, thereby driving the baffle 701 to move away from the network scanner 4 through the linkage structure 6, so that the first squeezing plate 604 no longer pushes against the second squeezing plate 605. The operator can disengage the baffle 701 from the interface of the network scanner 4, making it easier for the operator to remove the network scanner 4.

[0053] Furthermore, a fixing bracket 505 is fixedly provided at the top end of the moving rod 503 , a roller 506 is rotatably connected to the upper end of the fixing bracket 505 , and two ends of the return spring 504 respectively abut against the fixing bracket 505 and the fixing cylinder 501 .

[0054] The return spring 504 elastically abuts the fixed bracket 505 to drive the movable rod 503 out of the fixed cylinder 501. Furthermore, since the fixed bracket 505 is provided with a roller 506, the pressing assembly 5 can roll against the box cover 2 via the roller 506, reducing friction between the box cover 2 and the pressing assembly 5, making it easier to close the box cover 2 on the tool box body 1 and improving its service life.

[0055] Furthermore, the pressing assembly 5 also includes a connecting hose 507, and a nozzle 703 is fixedly provided on the side wall of the baffle 701. The nozzle 703 is connected to one end of the connecting hose 507, and the other end of the connecting hose 507 extends into the inner cavity of the fixed cylinder 501 and is fixedly connected to the fixed cylinder 501.

[0056] When the box cover 2 is closed on the tool box body 1, the moving rod 503 will be pressed. At this time, the moving rod 503 will drive the moving piston 502 to move to compress the gas inside the fixed cylinder 501, so that the gas passes through the connecting hose 507 to the nozzle 703 of the baffle 701, and the nozzle 703 is moved to spray gas at the interface of the network scanner 4, thereby automatically cleaning the particles and foreign matter remaining in the interface.

[0057] like Figures 4 to 7As shown, in order to further reduce the operating steps of the tool box, the shielding component 7 also includes a connecting sleeve 704 and a connecting spring 705. The connecting sleeve 704 is fixedly arranged on the inner wall of the tool box body 1. A push rod 706 is slidably connected to the connecting sleeve 704. One end of the push rod 706 is fixedly connected to the baffle 701. The baffle 701 is connected to one end of the connecting spring 705. The other end of the connecting spring 705 is fixedly connected to the side wall of the tool box body 1. The connecting spring 705 is configured to drive the baffle 701 away from the interface of the maintenance equipment.

[0058] When the box cover 2 is opened, the first squeezing plate 604 is disengaged from the second squeezing plate 605. At this time, the connecting spring 705 can drive the baffle 701 away from the interface of the maintenance equipment, and make the second squeezing plate 605 linked and always slide against the driving inclined surface of the first squeezing plate 604, so that the baffle 701 is automatically disengaged from the interface of the network scanner 4, making it convenient for the operator to use the network scanner 4, and the second squeezing plate 605 is reset to ensure that when the box cover 2 is closed again, the first squeezing plate 604 can continue to drive the second squeezing plate 605 to move.

[0059] In this embodiment, the shielding component 7 also includes a rubber sealing ring 702, which is arranged on the side of the baffle 701 facing the interface of the network scanner 4, and the rubber sealing ring 702 is configured to close the gap between the outer periphery of the interface of the network scanner 4 and the baffle 701.

[0060] The rubber sealing ring 702 can seal and protect the interface of the network scanner 4 to prevent water vapor from corroding the interface of the network scanner 4 through the gap between the outer periphery of the interface of the network scanner 4 and the baffle 701 .

[0061] like Figure 8 As shown, the shielding assembly 7 also includes a guide rod 707, a connecting piston 708, and a connecting tube 709. The connecting piston 708 is slidably arranged in the inner cavity of the connecting sleeve 704. One end of the guide rod 707 is fixedly connected to the upper surface of the connecting piston 708, and the other end of the guide rod 707 is fixedly connected to one end of the push rod 706. One end of the connecting tube 709 is fixedly connected to the inner cavity of the connecting sleeve 704. An inner cavity is provided inside the rubber sealing ring 702, and one end of the connecting tube 709 is fixedly connected to the inner cavity of the rubber sealing ring 702.

[0062] Among them, the guide rod 707 can connect the connecting piston 708 and the push rod 706. When the push rod 706 pushes the baffle 701 close to the interface of the network scanner 4, the connecting piston 708 will compress the gas in the inner cavity of the connecting sleeve 704, so that the gas in the inner cavity of the connecting sleeve 704 is output through the connecting tube 709 and transported to the inner cavity of the rubber sealing ring 702, so that the rubber sealing ring 702 is fully expanded, thereby further sealing the gap between the network scanner 4 and the baffle 701, further playing a role of sealing protection.

[0063] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
