technical field

The utility model relates to a fan door device of an automatic ticket checking machine, in particular to a shearing type fan door device of an automatic ticket checking machine at rail transit stations.

Background technique

With the continuous advancement of the urbanization process, the subway has gradually become one of the important means of transportation for people to travel. The subway generally adopts the way of automatic ticket checking into the station. When passengers pass through at a slow speed, the door of the automatic ticket checking machine may close, causing pain or crushing passengers. At the same time, in the event of a power failure, the automatic ticket gate door must be automatically opened.

Utility model content

The purpose of the utility model is to provide a door device of an automatic ticket checking machine that can be automatically opened when the door is subjected to external force, a foreign object is clamped or the power is cut off.

The specific scheme of the utility model is: a fan door device of an automatic ticket checking machine, comprising a coaxially arranged active arm and a fan door arm, a driving device of the master arm and a fan door installed on the fan door arm, and the fan door arm is equipped with The spring, the direction of spring force of the spring is the same as the opening direction of the door, and also includes a pin device arranged on the door arm and a pin stopper arranged on the active arm, the pin device includes a pin seat, and a compression spring installed in the pin seat And pinball, pinnacle pin stretches out pinball seat; Pinball stopper head is angular shape, and its two inclined-planes are respectively towards fan door opening direction and closing direction, and pinball pin and the inclined-plane of fan door opening direction offset. The spring can be a tension spring, compression spring or torsion spring, etc., preferably a torsion spring.

In order to reduce the resistance encountered by the main arm in the process of swinging to the working position, the slope of the slope in the direction of opening the door is smaller than the slope of the slope in the direction of closing the door.

As a further disclosure of the utility model, the driving device includes a motor, a worm reducer, a crank and a connecting rod connected in sequence, and the crank and the connecting rod, and the connecting rod and the active arm are respectively connected by pins.

In order to limit the opening limit of the door arm and reduce the impact of the door arm when the power is turned off, a buffer is also installed on the door arm. When the door is in the open state, the buffer contacts the base.

The device of the utility model realizes the setting of the force limit of the door arm by adjusting the slope of the inclined surface of the head of the pin stopper and the elastic force of the pressure spring in the pin device, that is, when the door is closed by external force or caught by foreign objects, The force value of the door arm breaking away from the main arm. The utility model has a simple structure, and the door can be opened automatically when it is subjected to external force, a foreign object is clamped or the power is cut off, and the safety performance is excellent.

Detailed ways

The door device of the automatic ticket checking machine as shown in FIGS. 1-4 includes a base 6 , a door assembly 1 , an active arm 204 , a driving device, a pin device 110 and a pin block 203 . The door assembly 1 includes a door 101, a door arm 102, a torsion spring 8, a torsion spring stop bolt 7 and a buffer 103, the door arm 102 is connected to the door 101 by screws, and the torsion spring stop bolt 7 is screwed into the fan On the projection of the door arm 102, the buffer member 103 is installed on the lower end of the leaf door arm 102 projection; the leaf door arm 102 is installed on the base 6 by the rotating shaft 9, and can rotate around the rotating shaft 9, and the torsion spring 8 is sleeved on the rotating shaft 9, One end of the torsion spring 8 is inserted into the base 6, and the other end rides on the torsion spring limit bolt 7. The pin device 110 comprises a pin seat 113, a pin 118, a stage clip 114, a preload screw 111, a set nut 112 and a connecting plate 119, and a through cavity is provided in the pin seat 113, and the pin pin 118 and the stage clip 114 are placed in a hollow space. In the cavity, then install the set nut 112 and the pre-tightening screw 111; the marble 118 extends out of the pin seat 113, and can be pressed into the pin seat 113 under the action of an external force; The elastic washer 117 is firmly connected with the connecting plate 119, and the connecting plate 119 is installed on the door arm 102. The active arm 204 is installed on the rotating shaft 9 and can rotate around the rotating shaft 9. The marble stopper 203 is welded on the active arm 204. The head of the marble stopper 203 is angular, and its two slopes are respectively towards the opening direction and the closing direction of the door. , the slope in the opening direction of the door is recorded as slope B, the slope in the closing direction of the door is recorded as slope C, and the slope of slope B is smaller than the slope of slope C. The driving device includes a motor 3, a worm reducer 4, a crank 207 and a connecting rod 206, the worm reducer 4 is installed on the worm reducer base 5, the worm reducer base 5 and the base 6 are connected by screws, the motor 3 and the worm reducer 4 Directly connected, the crank 207 is fixedly connected with the output shaft of the worm reducer 4 , the connecting rod 206 is connected with the crank 207 through the first pin 208 ; the connecting rod 206 is connected with the active arm 204 through the second pin 205 .

When working, the motor 3 drives the crank 207 and the connecting rod 206 sequentially through the worm reducer 4 , thereby pulling the active arm 204 to make the active arm 204 swing around the rotating shaft 9 . During the initial state, the door arm 102 is in the open state, the active arm 204 swings to the door arm 102, and the slope B of the pin stopper 203 is against the pins 118. Because the slope of the slope B is small, under the action of the slope B, the pin stopper will 203 presses the marble 118 into the pin seat 113, the pin stopper 203 crosses the blocking of the pin device 110 to make the active arm 204 reach the working position, and the slope C is against the pin 118; then the active arm 204 swings to the closing direction, because the slope C has a large gradient , the resistance of the inclined plane C and the marble 118 is enough to overcome the elastic force of the torsion spring 8, the driving arm 204 drives the door arm 102 to rotate, and the door is closed.

When an external force or a foreign object is caught during the closing process, and the force limit of the door arm 102 is exceeded, under the action of the slope C, the pin stopper 203 presses the pin 118 into the pin seat 113, and the pin stopper 203 crosses over The blocking of the marble device 110 separates the main arm 204 from the door arm 102, and the door arm 102 overcomes the gravity effect and reaches the open state rapidly under the torsion effect of the torsion spring 8, so as to avoid squeezing pain or crushing passengers.

When the power is cut off, the motor 3 is powered off, and the worm reducer 4 can rotate in the opposite direction. Under the action of the torsion force of the torsion spring 8, the door arm 102 and the active arm 204 are forced to swing in the opening direction until the buffer member 103 is in contact with the base 6. Touch, it is limited in the open state, and realizes power-off opening.
