Embodiment Construction

[0019] The present invention will be further described below in conjunction with drawings and embodiments.

[0020] Such as figure 1 As shown, the passive subway platform door lock includes a locking bolt part, a locking block part, a lock body guide rail part, and a lock body part.

[0021] The above-mentioned deadbolt components include a deadbolt block 8 , a deadbolt 2 , a deadbolt mounting plate 9 , and a deadbolt block cover plate 1 .

[0022] The lock pin block 8 is provided with a slot 81 for accommodating the lock pin.

[0023] The above-mentioned locking bolt 2 is T-shaped, its transverse side 21 is placed in the groove 81 in the locking pin block, and the straight side 22 can enter into the locking block 10 .

[0024] The front portion of the above-mentioned straight edge 22 is also provided with a reduced slope 23, which can better push away the upper locking roller bar 11 and the lower locking roller bar 11 (see below for details).

[0025] The above-mentioned l...

Abstract

The invention discloses a passive subway platform door lock, which comprises a locking plug pin part, a locking block part, a lock body part and a lock body guiding rail part for guiding the lock bodypart to move. The locking plug pin part comprises a locking plug pin, and the plug pin can be inserted into a channel, having a locking position, of a locking block; the locking block part comprisesthe locking block, an upper inclined groove is formed in the upper part of the locking block, a lower inclined groove is formed relative to the upper inclined groove, the inclining directions of the upper inclined groove and the lower inclined groove are opposite, locking rolling rods and rolling rod springs are placed in the upper inclined groove and the lower inclined groove correspondingly, thechannel for allowing the locking plug pin to pass through is formed between the locking rolling rod in the upper inclined groove and the locking rolling rod in the lower inclined groove, and after entering the channel, the plug pin is locked by a rolling rod plug pin; and the lock body part is connected with the locking block part and drives the locking block part to move to enable the locking plug pin to be locked or unlocked. The passive unlocking mode is adopted, thus the stability of a product is improved, the product does not have any problem after repeatedly acting for a long term, andthus the service life of the door lock is greatly prolonged.

Description

technical field [0001] The invention relates to a subway platform door lock. Background technique [0002] The full-height platform door in the subway platform needs a door lock to prevent it from being accidentally opened after the door body is closed. This kind of lock needs to be operated once every time the train arrives at the station. The failure of the lock will directly affect the safe operation of the entire full-height platform door, and the reliability of the mechanical structure of the lock is particularly important. [0003] The mechanical structure of the existing full-height platform door lock is that the limit block is stressed on one side and impacted on one side. After many times of opening and closing the door, it is easy to deform, thereby seriously reducing the service life of the door lock. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the above-mentioned shortcomings of the prior art an...
