Problems solved by technology

[0003] Three-bar turnstiles are more widely used in practical applications because of their simple structure, low cost, and no requirement for passage logic. In addition, because the three-bar blocking mechanism is relatively simple, it is easier to jump when blocking passing people or passing people drill through the gate to evade fares
The swaying and shaking between moving parts can easily cause friction between parts, resulting in serious wear and tear and increased maintenance costs

Abstract

The invention discloses a shearing-type door blocking device. A motor installation board is fixedly arranged on one side of a base, a servo motor is fixed to the installation board, a mother door rocker arm is rotatably connected with the base, a mother door and the mother door rocker arm are fixedly connected, and a child door which can be embedded into the mother door is rotatably connected withthe bottom of the mother door. A special-shaped crank provided with a long arm and a short arm is fixedly connected with a servo motor output shaft end, the other end of the long arm of the special-shaped crank is rotatably connected with one end of a connection rod, the other end of the connection rod is rotatably connected with one side of the child door, a middle end of the long arm of the special-shaped crank is rotatably connected with one end of a second connection rod, the other end of the second connection rod is rotatably connected with a middle end of the mother door rocker arm, theother end of the short arm of the special-shaped crank is connected with a tension spring, and the other end of the tension spring is connected with the base. According to the shearing-type door blocking device, a mode of the motor plus the connection rods can be directly used for driving a door plate, a worm and gear mechanism is omitted, and after being deenergized, the deenergized door plate can be reset directly through the tension spring. The shearing-type door blocking device has the outstanding advantages that the structure is simple, parts are easy to process, the maintenance cost islow, and the like.

Description

technical field [0001] The invention relates to a gate that can be used in rail transit such as subway, railway, light rail, and various access control systems, in particular to a scissor-type door blocking device for automatic ticket checking machines. Background technique [0002] With the development of national rail transit, automatic fare collection system is becoming more and more important in various fields. It has been widely and maturely used in various rail transits such as railways, subways, and light rails, and turnstiles are also an indispensable part of automatic fare collection systems. At present, according to the distinction of the blocking mechanism, the gates mainly have three different forms: three-bar, scissor gate, and revolving gate. [0003] The three-bar gate is more widely used in practical applications because of its simple structure, low cost, and no requirement for passage logic, etc., but it also has relatively large defects. For example, the t...
