Abstract

The utility model relates to mechanical engineering, namely to the designs of container protective flaps, and can be used to protect explosive cargo, for example, in container-type mine clearing installations. The container contains flaps with hinges secured using an axis with a spring and a stop in the lugs on the side walls of the container. The flaps' fixation units include a hook and a lever made in one piece and secured to an axis with a spring on the rear part of the container, a spring-loaded tongue with a protrusion secured to the container lid, and a counter loop on the container flap, wherein the hook and the spring-loaded tongue are made with an inclined surface to ensure the passage of the counter elements during their interaction, and the lugs on the side walls of the container are made with a stop. The utility model makes it possible to increase the automation of the process of opening and closing the container flaps while reducing the time for this convenience when performing the specified functions. 1 c.p. f-ly, 1 ill.

Description

The utility model relates to the field of mechanical engineering, namely to the designs of protective container flaps, and can be used to protect explosive cargo, for example, in container-type mine clearing installations.

A transport container is known (author's certificate No. 973432, IPC B65D 43/14, published on 25.11.1982), consisting of two parts, forming a body and a lid, connected by a hinge formed by bosses with sockets made on one part of the container, and an axis located on the other part of the container and mating with the sockets, and characterized in that a support wing is made on the lid above the axis, and the bosses are provided with a protrusion having a support and entry surfaces for the wings, located at an acute angle to each other.

Also known is a device for lifting and locking the hatch cover of a combat vehicle (patent RU 2690122 C2, IPC E05F 13/02, published 30.05.2019), comprising a lifting device in the form of a guide bar, levers and a latch mounted on the hatch cover, which is spring-loaded and pivotally fixed to the body of the combat vehicle, and in the closed position is fixed with latches, and characterized in that the guide bar is provided with a toothed rack interacting with spring-loaded latches installed in a carriage moving along the guide bar and pivotally connected with the body of the combat vehicle by means of a lever, a pressure bar is mounted on the toothed rack, pivotally fixed on the earrings and interacting with the latches, wherein one end of the pressure bar is pivotally connected to the lever fastened to the outer and inner handles, installed on the hatch cover.

The devices known from the prior art do not allow for automatic opening of the lid (hatch, sashes) without human intervention and ensure closing only by pressing on the sash.

The objective of the proposed utility model is to create a container that provides automatic opening of the flaps and their simple closing.

The technical result of the utility model consists in increasing the automation of the process of opening and closing the container flaps while reducing the time for these actions.

The claimed technical result is achieved, and the set task is solved by a container containing at least two flaps with hinges secured using an axle with a spring and a stop in the lugs on the side walls of the container, and flaps fixation units including a hook and a lever made as a single piece and secured on an axle with a spring on the rear part of the container. The mechanism includes a spring-loaded tongue with a protrusion secured on the container lid and a mating loop on the container flap, wherein the hook and the spring-loaded tongue are made with an inclined surface to ensure the passage of the mating elements during their interaction, and the lugs on the side walls of the container are made with a stop. The container flaps are made of armored steel.

The claimed device is illustrated by a drawing (Fig. 1) and, as an example, operates as follows.

Both flaps (1) of the container are provided with hinges (2) at the edges, which are secured in the lugs (5) on the side walls of the container using an axis with a bushing (3) and a spring (4) with a stop (11). The lugs (5) are secured to the side walls of the container. The claimed device also contains at least two flaps fixation units (one for each flaps). The container lid is made with a torsion principle of operation and, when the lock is remotely activated, rises smoothly under the action of the torsion. When the container lid is raised, the spring-loaded tongue (9) secured to the inside of the container lid acts with its projection on the lever (7), which is made integral with the hook (6), and forces the hook (6) to release the mating loop (10) on the container lid. Under the action of the spring (4) in each hinge (2), the container flap opens and rests against the stops of the eyes (5) (the stops are not shown in the drawing). The flaps are closed by returning the flaps to their original position and by pressing (pressing) at the last stage, during which the spring-loaded tongue (9), due to the inclined surface and the presence of the spring, passes the lever (7) and, under the action of the spring, is fixed by its projection resting against the lever, and the mating hinge (10) of the flap, sliding along the inclined surface of the catch (6), forces it to deviate and fix the loop with its catch.

Claims (2)

1. A container comprising flaps with hinges secured using an axle with a spring and a stop in lugs secured to the side walls of the container, and flaps fixing units including a hook and a lever made as a single piece and secured to an axle with a spring on the rear part of the container, a spring-loaded tongue with a protrusion secured to the lid of the container, and a counter loop on the container flap, wherein the hook and the spring-loaded tongue are made with an inclined surface to ensure the passage of the counter elements during their interaction, and the lugs on the side walls of the container are made with a stop. 2. The container according to item 1, characterized in that the doors are made of armored steel.
