military transport case

Abstract

The invention discloses a military transport box, which comprises a box body, a box cover, a motor and an opening and closing mechanism for opening and closing the box cover; the opening and closing mechanism includes a driving rod, a driven rod and a rotating shaft. The case cover is provided with a first groove for accommodating the rotating shaft and the driving rod. The rotating shaft is rotatably connected to the first side wall of the box body, and the axis of the rotating shaft is parallel to the side of the first side wall located at the opening of the box body. One end of the active rod is hinged with the case cover, the other end of the active rod is fixedly connected with the rotating shaft, and the axis of the active rod is perpendicular to the rotating shaft. One end of the driven rod is hinged with the first edge of the case cover, the other end of the driven rod is hinged with the first side wall of the case, and the driven rod is arranged outside the case. The motor is connected with the rotating shaft transmission. The invention provides a military transport box. The active lever hinged to the box cover is driven by a motor to rotate, and the box cover and the driven lever are driven to rotate and close. The movement process is stable and accurate, and the loss of kinetic energy is small.

Description

technical field [0001] The invention relates to the technical field of precision machinery, and more specifically, the invention relates to a military transport case. Background technique [0002] The transport box is organically combined with various strong materials to form a convenient and movable whole. The transport box is usually equipped with a vehicle and has high mobility. It is widely used in command systems, communications, medical care, and logistics support. It is an important equipment for the army. [0003] Military transport boxes usually have special requirements: large military transport boxes need to use a large torque to open the box cover; when performing confidential work, the opening and closing of the box cover has a silent requirement; when transporting precision instruments, the opening and closing of the box cover The process needs to reduce vibration; when the working environment is harsh, the open state of the box cover requires wind resistance....

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problems of asynchronous movement, poor stability, poor concealment, large power transmission loss, and high noise of the opening and closing mechanism of the existing transport box, the present invention innovatively provides a military transport box. The opening and closing of the military transport box The mechanism drives the active rod hinged with the case cover to rotate through the motor, driving the case cover and the driven rod to rotate and open, forming a four-bar linkage mechanism with stable and precise movement process and small kinetic energy loss
