Gate capable of preventing people in region from being dense

Abstract

The invention relates to a gate capable of preventing people in a region from being dense. The problem that the gate cannot limit the passing frequency is effectively solved. According to the technical scheme, the gate comprises a rotating shaft of the gate, a shell parallel to the rotating shaft is fixed to the outer wall of the rotating shaft, the interior of the shell is divided into a first cavity, a second cavity and a third cavity from bottom to top, and the first cavity and the second cavity are filled with liquid; the rotating shaft rotates to enable the first cavity to absorb liquid from the second cavity and then push the liquid in the first cavity into the third cavity, a first through hole is formed in the lower end of the third cavity, an annular sleeve is arranged outside the rotating shaft, teeth are evenly distributed on the circumference of the inner wall of the annular sleeve, a clamping block penetrating through the side wall of the third cavity in the radial direction is installed on the third cavity, and two pistons are installed in the third cavity; when liquid enters the third cavity too fast, the hydraulic pressure between the two pistons is increased to push the clamping block to move outwards to be clamped into the teeth to limit the rotating shaft. According to the invention, the passing frequency of the gate can be limited, and people in places in the gate can be prevented from being gathered and disordered.

Description

technical field [0001] The invention relates to the field of traffic equipment, in particular to a gate that prevents crowds in an area. Background technique [0002] The gate is a device that restricts traffic, and is widely used at the entrances and exits of airports, stations, communities, etc. The function of the gate is to limit the number of people passing each time, to avoid multiple people passing at the same time, to avoid crowding, and to facilitate ticket checks, security checks, etc. The work is carried out smoothly and orderly; the current gates only limit the number of people passing each time to achieve a single pass, but cannot limit the frequency of passing, which will cause the ticket check, security check or other work for the previous person to not be completed. The latter person has already entered the site through the gate, causing congestion in the site and confusion in related work places, which is prone to omission of personnel such as missed inspect...
