[0002] When working, airport navigation lights can assist aircraft takeoff and landing at night or in low visibility conditions, improving the safety of aircraft during operation. Airport navigation lights include approach lights, slope lights, runway entrance lights and runway centerline lights;

[0003] During the daily use of airport navigation lights, they need to be repaired and inspected regularly. When repairing airport navigation lights, a variety of maintenance tools such as screwdrivers, multimeters, oscilloscopes and safety belts are needed, and therefore, a tool box for airport navigation lights maintenance is needed;

[0004] When the staff is working, they need to repair multiple lamp bodies, and then they need to move the tool box all the time, that is, they need to open and close the tool box frequently. When the tool box is used, the lock is relatively complicated, which affects the staff's high-frequency opening and closing process;

[0005] In order to overcome the above-mentioned defects, prior art 1 (application number CN202021669226.8, Chinese patent application date 2020-08-12) is a portable tool box, which effectively reduces the angle of the box cover when the tool box is in use through the design of hook 1, support chain and hook 2, facilitates the quick opening and closing of the box cover, and improves the efficiency of tool access. The design of universal wheels, fixed plates and handles not only enables the tool box to be moved by rolling and carrying, thereby improving the portability of the tool box, but also greatly reduces the space occupied by the handle by conveniently folding the handle around the fixed plate, making the tool box more convenient to use and more practical.

[0006] However, when the box cover is opened during use, it is not convenient for the box cover to pop up by itself. When the tool box in the above application is used, the staff still needs to manually lift the box cover, which reduces the staff's work efficiency and brings unnecessary trouble to the maintenance work of the lamp body.

[0007] In view of the above problems, it is urgent to carry out innovative design based on the original navigation light maintenance tool box. Utility Model Content

[0008] The purpose of the present utility model is to provide a portable tool box for repairing airport navigation lights, so as to solve the problem in the above-mentioned background technology that when using the tool box, the staff still needs to manually lift the box cover, which reduces the staff's work efficiency and brings unnecessary trouble to the maintenance work of the lamp body.

[0009] To achieve the above-mentioned object, the present invention provides the following technical solution: a portable tool box for airport navigation light maintenance, comprising a box body and a box cover, wherein a base is fixedly connected to the lower surface of the box body, and a push rod is slidably provided inside the box body;

[0010] The box cover is hingedly connected to the upper surface of the box body, and a long board is fixedly connected to the upper surface of the box cover, and a handle is rotatably provided inside the long board;

[0011] A portable tool box for maintaining airport navigation lights, further comprising:

[0012] A fixing block, the fixing block being fixedly connected to the front side of the box body and being symmetrically distributed about the center of the box body;

[0013] A connecting plate is fixedly connected to the surface of the box cover.

[0014] Preferably, the back surface of the connecting plate is convex, and the lower surface of the connecting plate is an arc-shaped structure, and the connecting plate is an inverted "J" shape when viewed from the left.

[0015] Preferably, a long pin is rotatably provided inside the fixing block, and a pipe sleeve is fixedly connected to the surface of the long pin.

[0016] Preferably, a pressing block corresponding to the connecting plate is fixedly connected to the upper surface of the pipe sleeve, and the end of the pressing block is an arc-shaped structure, and the end of the pressing block is convex.

[0017] Preferably, a torsion spring having an elastic reset function is fixedly connected to the surface of the long pin, and the other side of the torsion spring is fixedly connected to the inner wall of the fixed block.

[0018] Preferably, the push rods are symmetrically distributed about the center of the box body, and a reset spring that performs elastic reset is fixedly connected to the lower surface of the push rods, and the other side of the reset spring is fixedly connected to the inner wall of the box body.

[0019] Preferably, the push rod passes through the interior of the box, and the end of the push rod is located outside the box.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: the portable tool box for repairing airport navigation lights adopts a new structural design, and its specific contents are as follows:

[0021] (1) When the portable tool box for airport navigation light maintenance is in use, the worker can directly rotate the box cover when he needs to change his position. When the box cover rotates, the connecting plate is driven to rotate synchronously. When the connecting plate rotates to contact the pressing block, the pressing block is pushed by the connecting plate. When the box cover rotates to a horizontal state, the pressing block is rotated back to its original position under the action of the torsion spring, and then the pressing block presses the connecting plate to close the box cover.

[0022] Furthermore, when the pressing block is driven by the connecting plate to work, the pressing block will drive the pipe sleeve and the long pin to rotate. When the long pin rotates inside the fixed block, the torsion spring will be stretched. When the pressing block is not in contact with the connecting plate, the long pin and the pressing block will rotate under the action of the torsion spring. The torsion spring plays a role of rapid rebound, making the pressing block work quickly.

[0023] (2) In the portable tool box for repairing airport navigation lights, when the box cover is open, the push rod is positioned outside the box body under the action of the return spring, and when the box cover is closed, the push rod moves in the direction of squeezing the return spring, that is, when the box cover is closed, the return spring is always in a compressed state;

[0024] Furthermore, when the box cover needs to be opened, the pressing block can be directly rotated. When the pressing block is not in contact with the connecting plate, the box cover will rotate around the hinge under the action of the push rod and the return spring. That is, the box cover will automatically rotate open without the staff touching it, thereby improving the staff's work efficiency.

[0025] (3) The push rods of the portable tool box for airport navigation light maintenance are symmetrically distributed on both sides of the box body, so that the push rods can better push the box cover and make the box cover evenly stressed. When the box cover and box body are not needed, the staff can move the box body through the long board and handle. The operation process is quick and convenient, and the portability is high.
