Description

Cargo compartment side door locking device

Technical Field

The utility model relates to a goods railway carriage or compartment side door locking device.

Background

The freight cars are provided with cargo compartments for loading cargos, two sides of each cargo compartment are provided with a side door capable of being turned up and down so as to facilitate loading and unloading, and a stand column is arranged between each side door and the front wall plate as well as between each side door and the rear door; the front end and the rear end of each side door are respectively provided with a handle, the handles are provided with clamping hooks, and the two upright posts are respectively provided with a corresponding lock hole; the existing handle lacks a locking function, the handle can be loosened due to frequent vibration in the running process of the truck, and then the hook on the handle is separated from the lock hole, so that the side door can be opened outwards when running, potential safety hazards exist, and further improvement is to be achieved.

SUMMERY OF THE UTILITY MODEL

To the current situation of the above prior art, the utility model aims to solve the technical problem that a can prevent that the handle is not hard up because of frequent vibration to eliminated the potential safety hazard, and simple structure, convenient operation's goods railway carriage or compartment side door locking device.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: a side door locking device of a cargo compartment is characterized by comprising a seat plate, a handle and a locking block; the handle and the locking block are rotatably connected to the front side of the seat plate, the locking block is arranged above the handle, a locking hook is formed outwards on the right side of the handle, a first stop block is formed outwards on the upper end of the handle, a second stop block is correspondingly formed outwards on the lower side of the locking block, and the second stop block is matched with the first stop block.

Preferably, a buckle plate is further formed outwards on the right side of the locking block.

Compared with the prior art, the utility model has the advantages of: the utility model discloses possess the locking function, can prevent that the handle is not hard up because of frequent vibration to avoid the side door to outwards open, eliminated the potential safety hazard, and simple structure, convenient operation.

Detailed Description

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art to which the invention belongs. The use of "first," "second," and similar terms in the description herein do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To maintain the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and components may be omitted.

As shown in fig. 1 to 4, a side door locking device for a cargo compartment comprises a seat plate 6, a handle 7 and a locking block 8; handle 7 and the equal rotatable connection of latch segment 8 are in the front side of bedplate 6, and the top of handle 7 is located to latch segment 8, and the right side of handle 7 is outwards formed with latch hook 71, and the upper end of handle 7 is outwards formed with first dog 72, correspondingly, and the downside of latch segment 8 is outwards formed with second dog 82, and second dog 82 mutually supports with first dog 72, and the right side of latch segment 8 is still outwards formed with buckle 81.

The front side and the rear side of a bottom plate 5 of the cargo compartment are respectively provided with a front coaming 1 and a rear door 4; the left and right sides in goods railway carriage or compartment all is equipped with two stands 2, all is equipped with a side door 3 between two stands 2 of homonymy, and the equal rotatable connection of downside of every side door 3 is on bottom plate 5, fixes bedplate 6 in the edge of one side of side door 3 to make lockhook 71 and the lockhole 21 on the stand 2 mutually support.

When in use, the handle 7 is rotated to the bottom, so that the lock hook 71 is inserted into the lock hole 21 from bottom to top; then, the buckle plate 81 is pulled downwards by a hand to drive the locking block 8 to rotate, so that the second stop block 82 rotates downwards to the right side of the first stop block 72 through a gap between the buckle plate 81 and the first stop block 72, as long as the handle 7 is loosened, the first stop block 72 rotates towards the direction of the second stop block 82 until the first stop block and the second stop block are attached to each other, the buckle plate 81 is pressed at the upper end of the first stop block 72 at the moment, and the handle 7 is locked to prevent the handle 7 from continuously rotating; similarly, if when needing the unblock, then rotate handle 7 to the end earlier for appear the clearance between buckle 81 and the first dog 72, reuse hand is stirred up buckle 81 in order to drive latch segment 8 reversal, until second dog 82 rotates the top of first dog 72 to the left, then just can reverse handle 7 so that latch hook 71 breaks away from lockhole 21, thereby realizes the unblock.

The utility model discloses possess the locking function, can prevent that the handle is not hard up because of frequent vibration to avoid the side door to outwards open, eliminated the potential safety hazard, and simple structure, convenient operation.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in the embodiments and modifications thereof may be made, and equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
