Problems solved by technology

Existing aviation aircraft still use screws to fasten the maintenance hatch cover. Although this design is simple, it needs to be disassembled one by one during maintenance, which wastes time and is prone to failure for a long time, which affects the attendance rate. For supersonic stealth aircraft, it is necessary The maintenance hatch cover is tightly fitted, and the shape of the fastener joint cannot change suddenly, and no leaking gaps and cavities are allowed. The traditional fastener connection cannot meet the requirements

Embodiment Construction

[0024] The following examples are further explanations and supplements to the present invention, and do not constitute any limitation to the present invention.

[0025] like Figure 1 to Figure 8 As shown, the rotary cover lock device of the present invention includes a base 10 , a rotating assembly 20 , a crank-slider mechanism 30 , a support 40 and a lock lever 50 . The rotating assembly 20 is rotatably connected to the base 10 and is connected to the crank-slider mechanism 30 . The crank-slider mechanism 30 is connected with the support 40 , which can convert the rotation of the rotating assembly 20 into a linear motion, thereby driving the support 40 to rotate around the base 10 , so that the locking rod 50 is released from the original position for locking or unlocking.

[0026] like Figure 1 ~ Figure 4 As shown, the base 10 is provided with a rotating shaft hole 11 for installing the rotating assembly 20 . The shaft hole 11 is a cylindrical through hole. In order to...

Abstract

A rotary cap locking device is characterized by comprising a base, a rotating assembly, a crank and slider mechanism, a support and a locking rod, wherein the rotating assembly is rotationally arranged on the base; one end of the crank and slider mechanism is connected with the rotating assembly, one end of the crank and slider mechanism is connected to the base in a limited manner, and the crankand slider mechanism can move relative to the base under the drive of the rotating assembly; the support is rotationally connected with the base and is in linkage connection with the crank and slidermechanism; the support is driven by the crank and slider mechanism to rotate around the base; and the locking rod is fixedly connected to the support; the rotating assembly can drive the crank and slider mechanism to move when rotating, and the crank and slider mechanism can drive the support to rotate around the base and further drive the locking rod to be separated from the original position when moving. The rotary cap locking device is reliable in connection, can prevent accidental unlocking, is convenient to operate and can greatly improve the convenience degree and efficiency of maintenance and overhaul.

Description

【Technical field】 [0001] The invention relates to the field of aviation, in particular to a rotary cover lock device suitable for quick unlocking and locking of an aircraft maintenance hatch. 【Background technique】 [0002] With the continuous development of aviation technology, the requirements for aviation structural parts are getting higher and higher. Existing aviation aircraft still use screws to fasten the maintenance hatch. Although this design is simple, it needs to be disassembled one by one during maintenance, which wastes time and is prone to failure for a long time, which affects the attendance rate. For supersonic stealth aircraft, it is necessary to The maintenance hatch cover is closely fitted, and the shape of the fastener connection cannot be changed suddenly, and the leakage of gaps and voids is not allowed. The traditional fastener connection cannot meet the requirements. Therefore, there is an urgent need for a locking device with convenient operation, s...
