Description

Quick locking device applied to movable fence of airport luggage trailer Technical Field The application relates to the technical field of luggage trailers, in particular to a quick locking device applied to movable rails of airport luggage trailers. Background The locking device of the movable fence on the luggage trailer is critical to the transportation safety of the goods, and the movable fence needs to be ensured to be stably closed in the transportation process so as to prevent the goods from falling or shifting. At present, a movable rail locking device of a luggage and cargo trailer used in each airport mainly adopts a door hook or a bolt structure of a truck rail plate, locking parts of the device are respectively arranged at two ends of the movable rail, and the movable rail is opened and closed by independent operation of the two ends. However, since the locking parts are distributed at two ends of the movable fence, operators need to operate the two ends respectively when closing the movable fence, so that the locking steps and time are increased, the operation is complicated, if forgetting to lock only one end of the movable fence, the safety problem is easy to generate, and the improvement is needed. Disclosure of utility model In order to reduce the operation steps when an operator closes the movable fence and shorten the locking time of the movable fence on the luggage trailer, the application provides a quick locking device applied to the movable fence of the luggage trailer of an airport. The application provides a quick locking device applied to an airport luggage trailer movable fence, which adopts the following technical scheme: The utility model provides an use quick locking device on airport luggage trailer movable rail, includes the trailer base member, the fixed rail guard that is provided with in length direction's both ends on the trailer base member, width direction's both ends are provided with side fixed rail and movable rail on the trailer base member, arbitrary the movable rail rotates to be connected on the trailer base member, arbitrary the both ends symmetry of length direction of movable rail is provided with the hasp seat, the position and the quantity setting that the side fixed rail corresponds the hasp seat, arbitrary be provided with on the side fixed rail and form joint complex quick locking structure with corresponding hasp seat. Through adopting above-mentioned technical scheme, utilize the lock catch seat on the movable rail to cooperate with the joint of quick locking structure on the side fixed rail, realized the quick locking of movable rail and side fixed rail and be connected, the locking mode that traditional needs to operate respectively at movable rail both ends has been abandoned, only need the staff upwards turn over the movable rail and put in place, can carry out synchronous locking with movable rail both ends, need not to go movable rail both ends round trip operation, shortened the operating time of staff locking movable rail, the operating efficiency has been improved, the potential safety hazard that produces because of forgetting operation one end has been avoided again. Preferably, the quick locking structure comprises a connecting plate, a locking plate, a cover plate, a first bolt, a second bolt and a connecting spring, wherein the connecting plate is welded on the side fixing fence, a first vertical groove and a second vertical groove are formed in the same vertical line of the locking plate, and an inclined groove communicated with the first vertical groove is formed in the locking plate; The first bolt is sequentially penetrated through the cover plate, the locking plate and the connecting plate in threaded connection, the first bolt is locked with the top of the first vertical groove or the top of the inclined groove in use, the second bolt is sequentially penetrated through the cover plate, the second vertical groove and the connecting plate in threaded connection, one end of the connecting spring is connected with the first bolt, the other end of the connecting spring is connected with the bottom of the first vertical groove, and a clamping hole for forming clamping fit with the locking plate is formed in the lock catch seat. By adopting the technical scheme, when the movable fence needs to be locked, the first bolt is clamped with the top of the inclined groove, a worker turns the movable fence upwards, so that the movable fence drives the lock catch seat to gradually turn upwards, the lock catch seat slowly pushes the locking plate, the locking plate rotates towards the inner side of the trailer matrix by taking the axial direction of the second bolt as a rotating shaft line until the locking plate is in a vertical state, at the moment, the first bolt is positioned in the first vertical groove of the locking plate, the locking plate integrally moves downwards under the action of the elasticity of the connecting spring, and when the low
