Abstract

The present invention relates to a tailgate coupling device of a freight car loading box, and in detail, as a coupling device between the sidegate and the tailgate when the cargo loading box is opened and closed, a frame 13 having an upper opening is fixed to the sidegate frame 15. And a sliding stop 11 coupled to the inside of the frame 13 and having a locking portion 11-1 on the upper side thereof, a lower surface of the sliding stop 11, and a bottom surface of the frame 13. It consists of an elastic body 14 interposed therebetween, and a hook 12 that is fixed to a tailgate frame 16 opposite to the frame 13 and engaged with the engaging portion 11-1.

When the sidegate and tailgate are coupled, the hook 12 fixed to the tailgate presses the catching part 11-1 protruding from the upper part of the slitting stopper 11, and at this time, the elastic body 14 embedded in the lower part is Compressed and the slitting stop 11 is moved to the bottom and the hook 12 is engaged with the engaging portion along the curved surface of the slitting stop.

When the coupling of the hook 12 is completed, a force to move the slitting stop 11 upward is generated by the reaction force of the elastic body 14 that has been compressed by the pressing force of the hook 12, thereby engaging the hook 12. The part 11-1 is strongly coupled, and when the coupling is released, when the slitting stop 11 is pressed downward, the slitting stop 11 is pushed by the compression of the elastic body 14, 1) is released from the restraint of the hook 12.

The method relates to a tailgate coupling device of a cargo vehicle loading box capable of easily and quickly and safely engaging and releasing sidegates and tailgates in the same way.

Description

Tailgate linkage of lorry loading bin

In general, the loading box of a lorry consists of two sidegates, one tailgate and the bottom of the loading box. The sidegates and tailgates are connected to the side rail assembling, and the floor is fixed to the cross follower joist. It is wrapped in a hollow side rail attached to the lower joist. When closing the loading box, that is, when the gates are vertically connected to each gate, the front part of the side gate is combined with the front guard frame, and the rear part is formed with the rear post to form the side frame by using the knob to combine the side. The gates are erected vertically, and the tailgates can be closed by attaching them vertically by fixing them to the erected sidegates.

The coupling structure of the conventional sidegate and tailgate is provided with a lever bent through the upper side of the tailgate frame 22 and coupled to the hanger 21-1 formed at the sidegate frame 21, and the other end thereof is Composed of the engaging bar 23 is formed with a locking jaw (23-2) to prevent the separation from the through-hole of the tailgate frame 22, when the lever 23-1 is pushed to the tailgate side to the upper coupled bar ( The coupling between the 23 and the latch 21-1 is released, and the lever 23-1 is pulled toward the side gate in the upright state. However, the coupling device of the side gate and tail gate is exposed to the outside and contaminated with contaminants such as rain or dust, resulting in rust or debris, which causes severe noise or malfunction when operating. There is a danger of a safety accident.

The technical problem to be achieved by the present invention is to provide a device that facilitates the opening and closing of the storage box to facilitate and secure the coupling and release of the side gate and tail gate to solve the above problems.

The construction for achieving the technical problem to be achieved by the present invention is to form a frame with an upper opening in the sidegate frame of the rear side of the sidegate to be fixed to the sidegate frame, the sliding is coupled to the inside of the frame and the top portion It is composed of a slitting stopper provided, an elastic body embedded between the bottom surface of the sliding stopper and the frame bottom, and a hook that is fixed to the tailgate frame opposite to the frame and coupled to the engaging portion.

When described in detail with reference to the drawings as follows.

The upper part is opened in the side gate frame 15 of the rear end surface of the side gate and is slittingly coupled to the inside of the frame 13 provided with the locking jaw 13-1 to form a rounded upper portion, and the end is bent in the opposite direction to the gate frame. The sliding part 11-1 is provided and a sliding stop 11 having a locking stand 11-2 coupled to the locking step 13-1 on the side to prevent the departure from the frame 13 and the above. The hook 12 is fixed to the tailgate frame 16 facing the frame 13 and coupled to the round portion formed in the locking portion 11-1, and is bent downwardly.

Hereinafter, the operation will be described.

When loading the tailgate of the cargo vehicle equipped with a tailgate coupling device provided with the present invention when combined with the sidegake.

When the slitting is coupled to the frame 13 and the elastic body 14 is interposed between the lower surface and the bottom of the frame, the hook 12 is formed in the upper portion of the body so that the end portion of the hook 12 provided at the side gate frame 16 starts to contact first. At this time, the end of the hook 12, which is bent downward, presses the round catching portion 11-1 of the upper surface of the slitting stopper, thereby compressing the spring 14 embedded in the lower side of the slitting stopper 11 and hooking the hook 12. Is a rounded bent portion inside the hook 12 and the top surface engaging portion 11-1 of the slitting stopper 11 riding on the curved surface of the rounding portion 11-1 on the upper side of the slitting stopper 11. It is coupled strongly by the upward movement of the slitting stop 11 by the reaction force of the spring 14, which is coupled and simultaneously. Conversely, if you unlink the tailgate from the sidegate.

When pressing the upper part of the slitting stop 14, when the spring 14 is compressed, the engaging portion 11-1 of the slitting stop is separated from the hook 12, and the coupling is released. The bond with is released.

When the coupling of the hook 12 is released, the slitting stop 11 moves upward due to the reaction force of the compressed spring 14, and at this time, the hanger 11-2 provided in the slitting stop 11 It is coupled to the locking step 13-1 provided in the frame upper portion and the slitting stop 11 prevents the departure from the frame (13).

The effect of the present invention can easily and securely combine and release the sidegate tailgate, so that rust occurs in the prior art, which causes a malfunction or makes a lot of noise, which requires a lot of power, and prevents a safety accident. It works.

The present invention relates to a tailgate coupling device of a lorry, and in detail, a coupling device of a sidegate and a tailgate when the cargo box is opened and closed, the upper part of which is formed in a round frame at the rear frame of the sidegate to release the hook and the hook fixed to the tailgate. It relates to a tailgate coupling device of a freight car loading box that is easy to disengage the sidegate and the tailgate by fixing a frame having a built-in slitting stopper having an engaging portion that is freely coupled to the lower portion and freely moving up and down. .
