Embodiment 1

[0028] Embodiment 1: The displacement of the core part of the electromagnet is set to be equal to or slightly greater than the distance between the locking groove 5.1 and the limiting part 5.2.

Embodiment 2

[0029] Embodiment 2: The limit portion 5.2 is set high enough so that the stop pin 206 can enter the limit portion 5.2 from the lock groove 5.1 without exceeding the limit portion 5.2.

Embodiment 3

[0030] Embodiment 3: The bracket is also provided with a second guide post 305, and the second guide post 305 is arranged under the swing plate 5, wherein, when the hook plate 2 is locked, it is used to limit the The degree of downward rotation of the swing plate 5 prevents the two swing plates 5 from turning downward excessively due to the excessive lifting of the stop pin 206, and the stop pin 206 cannot be stuck in the limit portion 5.2.

[0031] When locking, touch the two swinging plates 5 to make the swinging plates 5 rotate, and the locking limit part formed by the two limiting parts 5.2 releases the locking limit function, and the hook plate 2 falls into the locking recess under the action of gravity. Groove 5.1, under the action of gravity of the hook plate 2, the swing plate 5 swings until the two locking grooves 5.1 overlap, so that the stop pin 206 falls into the locking groove 5.1 to complete the locking.

Abstract

The invention discloses a platform door electromagnetic lock cylinder. The platform door electromagnetic lock cylinder comprises an electromagnet, two swinging plates, a hook plate and a support. The electromagnet is fixed to the support; the magnetic core portion of the electromagnet is connected with the hook plate; the hook plate can slide up and down to be mounted on the support; the hook plate is provided with a stop pin; each swinging plate comprises a swinging plate body, wherein a locking groove is formed in the middle of the upper edge of the swinging plate body, a limiting portion is arranged at one end of the upper edge of the swinging plate body, a swinging portion is arranged at one end of the lower edge of the swinging plate body, and the swinging portion and the limiting portion are located on the same side; the swinging portions of the two swinging plates can be rotationally mounted on the support, and the two swinging plates are arranged oppositely; during locking of the hook plate, the two swinging plates swing to the position where the locking grooves coincide, and the stop pin falls into the locking grooves; and during unlocking of the hook plate, the limiting portions of the two swinging plates swing to the stop pin. The invention further discloses an electromagnetic lock system. The stop pin is clamped in the two special swinging plate structures, unlocking or locking is achieved, the stability is good, and a response is made in time.

Description

technical field [0001] The invention relates to the field of rail transit devices, in particular to an electromagnetic lock cylinder for a platform door and an electromagnetic lock system thereof. Background technique [0002] Rail transit has an increasing impact on people's daily life. As an important part of rail transit equipment, platform doors must have good stability and accuracy to ensure the normal operation of the entire rail transit operating system. Whether the sliding door, which is the main moving part of the platform door, can work normally will seriously affect the stability of the whole system. [0003] At present, the electromagnetic locks used in domestic rail transit mainly have the following problems: 1) poor stability, frequent error reports and mechanical failures; 2) lagging and untimely response, affecting train operation. Contents of the invention [0004] (1) Technical problems to be solved [0005] Aiming at the defects of poor stability, lag...
