Problems solved by technology

[0002] At present, most of the cabin raceways are fastened to the profile under the aircraft floor, quickly connected to the aircraft ground rail through a bolt, or directly installed in the reserved raceway groove of the floor. The installation, disassembly and maintenance of the fastened connection are relatively difficult. , the quick connection with the aircraft ground rail will cause a large increase in the weight of the empty aircraft, and the installation in the reserved raceway groove of the floor has higher requirements on the aircraft structure and technological level

Embodiment Construction

[0028] Such as figure 1 As shown, the present invention is a quick-release lock for fixing the raceway of the engine room. The quick-release lock includes an eccentric handle 1, a pin 2, a bead 3, a rotating shaft 4, a bayonet pin 5, a spring 6, a sleeve 7 and a pin seat 9;

[0029] Be square column 3a in the middle of bead 3, and two ends are identical block 3b, and the width and height of block 3b are all greater than the width and the height of square column 3a; Bead 3 upper surface is even;

[0030] The pin 2 from top to bottom is the lug part 2a, the support part 2b and the pin head 2c; The through groove, which is adapted to the shape of the bead 3; and extends upward from the two side walls of the through groove to form two lugs, that is, the lug part 2a, and the two lugs are opened with eccentric The mounting hole of the handle 1; the pin head 2c has a cylindrical shape, and a radial bayonet through hole is opened at the bottom end of the pin head 2c; in the axial di...

Abstract

The invention belongs to the technical field of aviation, and relates to a rapid release lock for fixing a cabin raceway. The rapid release lock mainly comprises an eccentric handle, a pin, a depression bar, a rotating shaft, a bayonet pin, a spring, a sleeve and a pin boss. When the rapid release lock is operated, the bayonet pin penetrates through a floor bayonet pin hole and is clamped in a groove in the pin boss, and is locked through the depression bar. When the rapid release lock is not operated, the eccentric handle is turned and rotated, and the bayonet pin is pulled out from the floor bayonet pin hole. The rapid release lock overcomes the disadvantages of inconvenience in dismounting, difficulty in maintenance and overlargeaccessory weight of the traditionalraceway mounting mode, and provides a convenient, rapid, economical and reliable rapid releasedevice.

Description

technical field [0001] This patent belongs to the field of aviation technology, and relates to a quick-release lock for fixing the raceway of the cabin. Background technique [0002] At present, most of the cabin raceways are fastened to the profile under the aircraft floor, quickly connected to the aircraft ground rail through a bolt, or directly installed in the reserved raceway groove of the floor. The installation, disassembly and maintenance of the fastened connection are relatively difficult. , Quick connection with the ground rail of the aircraft will cause a large increase in the weight of the empty aircraft, and the installation in the reserved raceway groove of the floor has higher requirements on the aircraft structure and technological level. The purpose of the present invention is to provide a quick-release lock for the raceway of the aircraft cabin, through the cooperation of the bayonet pin on the pin and the groove of the pin seat under the floor, the quick i...
