Abstract

1. Люк, содержащий корпус, крышку и запорное устройство, отличающийся тем, что запорное устройство выполнено в виде резьбовой шпильки фасонной формы с секретным элементом для антивандальной защиты люка и обеспечивающим монтаж-демонтаж запорного устройства только при помощи специального нестандартного инструмента, шпилька оснащена внутренним осевым сквозным отверстием и упорным буртиком размещенным на наружном диаметре шпильки на определенной ее длине, один конец шпильки на резьбе в глухом отверстии соединен с крышкой люка, другой резьбовой конец шпильки установлен с зазором в корпусе люка с возможностью бокового и продольного перемещения и снабжен ограничительным устройством осевого перемещения шпильки, состоящим из стандартных крепежных элементов, например, из шайбы, гайки, шплинта, секретный элемент выполнен в виде сквозного отверстия в шпильке расположенного на определенной ее длине перпендикулярно осевой линии, в крышке люка соосно с внутренним осевым отверстием шпильки и равным ему по диаметру выполнено сквозное отверстие.2. Люк по п.1, отличающийся тем, что между торцом шпильки и крышкой люка размещена прокладка из эластичного материала, например, резины с выполненными в ее центральной части расходящимися от центра к периферии прорезями, а соосно внутреннему осевому отверстию в шпильке на определенной длине выполнено глухое отверстие.3. Люк по пп.1 и 2, отличающийся тем, что диаметр сквозного осевого отверстия шпильки под отверстием секретного элемента выполнен меньшим диаметра этого отверстия над отверстием секретного элемента, а длина резьбы глухого отверстия в крышке люка, в которое вворачи1. A hatch comprising a housing, a lid and a locking device, characterized in that the locking device is made in the form of a threaded pin with a secret element for anti-vandal protection of the hatch and providing mounting and dismounting of the locking device only with a special non-standard tool, the pin is equipped with an internal axial a through hole and a thrust collar located on the outer diameter of the stud at a certain length, one end of the stud on the thread in the blind hole is connected to the manhole cover, the other cut the lateral end of the pin is installed with a gap in the hatch housing with the possibility of lateral and longitudinal movement and is equipped with a limiting device for axial movement of the pin, consisting of standard fasteners, for example, from a washer, nut, cotter pin, a secret element is made in the form of a through hole in the pin located on a certain its length is perpendicular to the axial line, in the manhole cover coaxially with the axial bore of the stud and equal to the diameter of the through hole. 2. A manhole according to claim 1, characterized in that between the end of the stud and the manhole cover there is a gasket made of elastic material, for example, rubber with slots diverging in its central part from the center to the periphery, and a blind is made coaxially with the axial hole in the stud for a certain length hole. 3. The hatch according to claims 1 and 2, characterized in that the diameter of the axial through hole of the stud under the hole of the secret element is made smaller than the diameter of this hole above the hole of the secret element, and the thread length of the blind hole in the manhole cover, into which

Claims

1. A hatch comprising a housing, a lid and a locking device, characterized in that the locking device is made in the form of a threaded pin with a secret element for anti-vandal protection of the hatch and providing mounting and dismounting of the locking device only with a special non-standard tool, the pin is equipped with an internal axial a through hole and a thrust collar located on the outer diameter of the stud at a certain length, one end of the stud on the thread in the blind hole is connected to the manhole cover, the other cut the lateral end of the pin is installed with a gap in the hatch housing with the possibility of lateral and longitudinal movement and is equipped with a limiting device for axial movement of the pin, consisting of standard fasteners, for example, from a washer, nut, cotter pin, a secret element is made in the form of a through hole in the pin located on a certain its length is perpendicular to the axial line, in the manhole cover coaxially with the inner axial hole of the pin and equal to the diameter of the through hole.

2. The hatch according to claim 1, characterized in that between the end of the stud and the hatch there is a gasket made of elastic material, for example, rubber with slots diverging in its central part from the center to the periphery, and coaxially with the axial bore in the stud for a certain length a blind hole is made.

3. The hatch according to claims 1 and 2, characterized in that the diameter of the axial through hole of the stud under the hole of the secret element is made smaller than the diameter of this hole above the hole of the secret element, and the thread length of the blind hole in the manhole cover into which the locking pin is screwed is made smaller or equal to the distance from the thrust collar of the stud to the hatch body at the installation location of the stud in the hatch when closing it with a locking device.
