Description

Small-spacing limiting lock device and method for limiting of collector Technical Field The invention belongs to the technical field of aviation freight industry, and relates to a small-spacing limiting lock device and method for limiting a collector. Background The limiting lock device is matched with a civil aircraft freight system, is usually arranged in a standard floor sliding rail and is used for reliably limiting the course or reverse course and the vertical direction in the air transportation process of the collector. The limiting device is reasonably arranged, so that the container can be accurately locked at the corresponding loading position. Among the prior art, patent CN 202414165U discloses an aviation container limit lock, including rectangle lock frame, locate the first axle and the second axle in the lock frame, first axle is equipped with first lock body and makes the upright first pressure spring of first lock body, be equipped with the second lock body on the second axle and oppress the second pressure spring of lying in the rectangle lock frame with the second lock body, when first lock body and second lock body alternately are established, the lug of the second lock body is located the notch of the first lock body. The limiting lock for the aviation container has the characteristics of simple structure, easiness in operation and good fixing effect. However, the locking and unlocking of the structure are realized by pressing the lock body, the whole cargo transportation system is provided with hundreds of limit locks, and people bend down to press the lock body to realize the locking and unlocking processes, which is time-consuming and labor-consuming. In the prior art, patent US20120119052A1 discloses a METHOD FOR PRODUCING A FUNCTION ELEMENT comprising a new design of functional ELEMENTs, the structural features of which include a fixed track with a plurality of protrusions and movable staples. The fixing nails can fix the positions of the functional elements in the seat rails when in blocking positions, but the fixing nails are complex to install and inconvenient to detach. Through the analysis of the prior patent, the bidirectional limiting device can realize bidirectional locking of the collector with the limiting distance ranging from 19mm to 47mm, and the limiting distance is large. Disclosure of Invention The invention aims to solve the problems that the prior limiting device is complex in installation, inconvenient to detach, unchanged in locking or unlocking mode and incapable of adapting to smaller lock hole spacing in the prior art when the prior limiting device is used for blocking and limiting, and provides a small-spacing limiting lock device for limiting a collector. In order to achieve the purpose, the invention is realized by adopting the following technical scheme: The small-spacing limiting lock device for limiting the collector comprises a lock shell, wherein a first shaft and a second shaft which are parallel are arranged in the lock shell, and a quick-release joint assembly is arranged in the lock shell and is used for being connected with a rail to be assembled; The first shaft is provided with a locking pressing plate and a second lock tongue, the locking pressing plate is positioned on one side of the second lock tongue away from the second shaft, an elastic piece is arranged between the locking pressing plate and the second lock tongue, the position, close to the end part, of the first shaft is provided with an unlocking pedal and a locking pedal rod, and the second shaft is provided with the first lock tongue; the lower end of the second lock tongue is provided with a through groove, and the end part of the first lock tongue, which is far away from the second shaft, penetrates through the through groove; In an initial state, the lock pressing plate, the second lock tongue and the first lock tongue incline towards the course direction and are horizontally arranged in the lock shell; When the lock is locked, the pedal lever is stepped on, the first shaft is driven to rotate clockwise by the pedal lever, the lock pressing plate and the second lock tongue rotate clockwise in the same direction, the first lock tongue is pushed to rotate, the rotation is stopped until the lock pressing plate, the second lock tongue and the first lock tongue are in a vertical state, at the moment, the upper part of the first lock tongue penetrates through the through groove, the first lock tongue and the second lock tongue are in a crossed state, and the elastic piece is in a compressed state; when the lock is unlocked, the lock pedal is stepped on by foot, the unlock pedal drives the first shaft to rotate anticlockwise, and the lock pressing plate, the second lock tongue and the first lock tongue topple towards the course direction and return to the initial state. The invention further improves that: a limiting groove is formed in the side face, far away from the second shaft, of t
