Opening and closing device of gate machine passage

Abstract

The invention aims at providing an opening and closing device of a gate machine passage. The opening and closing device of the gate machine passage comprises leaf door, a base, a frame, a guide rail mechanism, a connecting rod swinging mechanism, a driving mechanism and the like, wherein the guide rail mechanism is arranged on the base and connected with the leaf door in a movably matched manner;the connecting rod swinging mechanism is arranged on the frame, wherein one end of the connecting rod swinging mechanism is rotationally connected with the leaf door and used for enabling the leaf door to move on the guide rail mechanism and between a door closing position and a door opening position of the gate machine passage in a reciprocating manner; and the driving mechanism is rotationally connected with the other end of the connecting rod swinging mechanism and used for driving the connecting rod swinging mechanism to swing. Compared with the prior art, the opening and closing device ofthe gate machine passage has the advantages that the gate machine passage does not need to be closed or opened by using a mode of rotating the leaf door; and the use demand of opening and closing control of the leaf door can be satisfied in the case of not using structures such as a supporting shaft and a gearbox; and therefore, a transmission structure is simplified, the friction of the openingand closing device in the operation process can be reduced, the moving accuracy can be improved, the stable operation of the connecting rod swinging mechanism can be guaranteed, and the service life of the opening and closing device can be prolonged.

Description

technical field [0001] The invention relates to a gate, in particular to a switch device for a gate channel. Background technique [0002] At present, the opening and closing doors of the existing turnstiles are usually three types: the three-bar type, the fan type and the side-opening type. [0003] However, because the existing three-bar type adopts a rotating method, each oblique bar needs to be rotated 120 degrees each time to allow a pedestrian to pass, and it is very easy to cause a collision with a pedestrian when the card is not in place during use. In addition, when pedestrians lead items such as luggage or pedestrians who are fatter to pass, great inconvenience and unnecessary trouble are caused due to the blocking of the oblique rod. However, due to the complex structure and high cost of the fan door type, it is easy to fail to operate normally due to circuit failure. [0004] The existing side-opening type switch door does not move in a translational manner bec...

Problems solved by technology

[0003] However, because the existing three-bar type adopts a rotating method, each oblique bar needs to be rotated 120 degrees each time to allow a pedestrian to pass through, and it is very easy to swipe the card in the process of use, resulting in collision with pedestrians.

In addition, when pedestrians lead luggage and other items or pedestrians with a fatter body pass, it will cause great inconvenience and unnecessary trouble due to the blocking of the oblique rod.

However, due to the complex structure and high cost of the fan door type, it is easy to fail to operate normally due to circuit failure.

[0004] The existing side-opening type switch door does not move in a translational manner because it is opened and closed by itself, but rotates in an arc around a support shaft, and the support shaft or fulcrum needs a support fan. The weight of the door, therefore, requires a high strength of the support shaft, and at the same time, it is necessary to use a high-power motor to drive or configure a gearbox through a low-power motor to solve the problem of the support shaft or fulcrum torque and speed, as shown in the patent disclosure document As disclosed in 201320428775.X, the transmission structure is complicated, the control precision is high, and the cost is high.
