Problems solved by technology

At present, the locking mechanism used on the vehicle is mainly opened and closed in the left and right directions, but in some places where the left and right operation space is not enough, a mechanism that can meet the requirements and can lock the front and rear directions is needed. Using the link mechanism is easy to cause stagnation, and the locking mechanism cannot realize normal opening and closing

Embodiment Construction

[0009] Embodiments of the present invention are described in detail below in conjunction with the accompanying drawings:

[0010] Reference attached figure 1 and attached figure 2 , an embodiment of the present invention: when the lock handle composition 1 rotates upwards to a vertical position, the bolt connecting plate 6 is pulled by the lock handle to move upward, and the lower bolt connecting rod 13 is pulled by the bolt connecting plate 6 to move upward, because the lower bolt The connecting rod 13 is limited by the linear bearing 11 and can only keep moving up and down. The lower dead bolt connecting rod 13 moves upward, and the tooth bar 7 and the lower dead bolt 14 installed on the lower dead bolt connecting rod 13 move upward together, together with the tooth bar 7 The meshed gear 8 rotates under the drive of the rack 7, the right driving link 9 rotates with the gear 8, and driven by the right driven link 10 and the left driven link 12, the left and right side bolts...

Abstract

The invention aims to provide a locking mechanism. The locking mechanism can be installed in a limited space, and requirements of a vehicle for a two-stage locking function, a front-and-back lock handle unlocking direction, multipoint locking through one handle, safety, reliability and the like of the locking mechanism can be met.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a locking mechanism. Background technique [0002] With the rapid development of my country's urban rail transit, cities around the world are considering the development of underground railway traffic to alleviate urban traffic congestion. In order to ensure the safety of vehicle operation and the tightness of the vehicle, the requirements for the locking mechanism are getting higher and higher. From the perspective of safety, first of all, the locking mechanism cannot be opened due to the vibration or impact of the vehicle, or human misoperation. This requires a secondary locking of the locking mechanism, and it also needs to meet the requirements for easy opening when needed; from the sealing In terms of consideration, multi-point locking is required to ensure that the mechanism that needs to be locked is closely connected with the car body. At present, the l...
