Flow-limiting revolving door

Abstract

The invention relates to a flow-limiting revolving door. The flow-limiting revolving door effectively solves the problem that a gate cannot limit the passing frequency. According to the technical scheme, the flow-limiting revolving door 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, a piston is installed in the third cavity, the rotating shaft rotates to enable the first cavity to suck 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, a fixed annular sleeve is coaxially 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, if the rotating shaft rotates too fast, the liquid can enter the third cavity too fast, the clamping block can be pushed outwards after the piston moves upwards to exceed the highest position, and the outer end of the clamping block is inserted into the teeth of the annular sleeve; and according to the flow-limiting revolving door, 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 current-limiting revolving door. 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 inspections;...
