Description

Wagon door knife

Technical Field

The utility model relates to a vehicle accessory, specifically speaking especially relates to a freight train door sword.

Background

A truck door knife is mainly used for trailers, trucks, semitrailers and the like, is generally made of high-quality steel plates by mechanical stamping, and is durable in use and strong in bearing capacity. Four side plates are arranged around the wagon box body, the rear side plate, the left side plate and the right side plate can be opened under the general condition, the bottoms of the rear side plate and the left side plate and the right side plate are connected with the wagon box body in a hinged mode, and the upper part of the rear side plate and the left side plate are fixed through a rotating shaft fixed by threads and a door knife welded between the side plates. Because the transportation road is uneven, cause the pivot to rotate very easily for the pivot below can't continue to keep in the U type inslot of door sword, this just leads to box curb plate top to open passively very easily, and transportation security reduces, and the goods condition that drops takes place occasionally.

At present, a truck door vane which is simple in structure and convenient to use and has the advantages that the limit block, the compression leg and the spring limiting mechanism are arranged on the door vane body to effectively protect the two sides of the door vane, so that the rotating shaft is prevented from rotating and the side plate of the box body is prevented from being opened mistakenly.

Disclosure of Invention

The utility model aims at providing a freight train door sword to solve and lack a simple structure among the prior art, convenient to use sets up stopper and compression leg, spring stop gear on the through-door cutter body and plays the effective protection of door sword bilateral face, prevents that the pivot from rotating, causes the problem of the freight train door sword that the box curb plate was opened by mistake.

The utility model discloses a realize through following technical scheme:

a truck door knife comprises a door knife body, wherein a U-shaped groove is formed in the door knife body, and a stop block is arranged on one side of the door knife body; the door knife body opposite side is equipped with the hole groove, is equipped with annular separation blade I on the hole groove, and the hole inslot is equipped with spring and compression leg, is equipped with annular separation blade II on the compression leg, and spring one end and hole groove bottom surface contact, the spring other end and II contacts of annular separation blade.

Furthermore, the pressing column is provided with an inclined plane.

Furthermore, a welding hole is formed in the door knife body.

Compared with the prior art, the beneficial effects of the utility model are that:

1. simple structure, convenient use and convenient welding.

2. Set up dog and compression leg, spring stop gear on the through-door cutter body and play the effective protection of door sword bilateral face, prevent that the pivot from rotating, cause the box curb plate to open by mistake.

3. The inclined plane is convenient for rotating the lower rotating shaft at the beginning, and when the rotating shaft rotates in a lateral direction, the rotating shaft can continue to rotate by manually pressing the pressing column.

Detailed Description

The invention will be further described and illustrated with reference to the accompanying drawings.

Embodiment 1, a truck door knife, including a door knife body 2, the door knife body 2 is provided with a U-shaped groove 7, one side of the door knife body 2 is provided with a stop block 6; the other side of the door knife body 2 is provided with a hole groove 10, the hole groove 10 is provided with an annular separation blade I8, the hole groove 10 is internally provided with a spring 11 and a compression leg 5, the compression leg 5 is provided with an annular separation blade II 9, one end of the spring 11 is contacted with the bottom surface of the hole groove 10, and the other end of the spring 11 is contacted with the annular separation blade II 9.

Embodiment 2, a freight car door vane, the compression leg 5 is equipped with the inclined plane 4; the door knife body 2 is provided with a welding hole 3, and the rest is the same as that of the embodiment 1.

When in use, the door knife body 2 is welded on the side plate of the box body, and the rotating shaft 1 is arranged on the side foot plate of the box body. The welding holes 3 facilitate welding. Rotatory pivot 1, 1 interlude contact inclined plane 4 of pivot, take the advantage of the situation and push down compression leg 5, spring 11 is compressed, after 1 interlude of pivot rotated compression leg 5, spring 11 rebounds the normal position, and then rebounds the normal position with compression leg 5, so jolt in the transportation can not cause pivot 1 to rotate yet, and the left and right sides of pivot 1 is blocked spacingly by compression leg 5 and dog 6, has increased the security of transportation. When the folding type folding door is opened, the pressing column 5 is pressed by hands, and then the rotating shaft 1 is rotated.
