Description

Technical Field

[0001] This utility model relates to the field of rail transit vehicle door technology, specifically to a locking mechanism for rail transit vehicle doors. Background Technology

[0002] Existing rail transit vehicle door locking mechanisms mostly employ single latches or electromagnetic drive devices, which suffer from problems such as complex structures, high maintenance costs, and susceptibility to unlocking failure due to external interference. Some mechanisms lack two-way locking functionality after the door is closed, posing a safety hazard. Furthermore, the interlocking structure between the door and the car body in existing technologies typically lacks a buffer design, leading to component wear over long-term use. Therefore, there is an urgent need for a locking mechanism that is simple in structure, reliable in locking, and possesses a buffer function. Summary of the Invention

[0003] The purpose of this utility model is to provide a locking mechanism for rail transit vehicle doors, which achieves bidirectional locking through mechanical linkage, has a compact structure, and has a buffer function, thereby solving the above-mentioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A locking mechanism for rail transit vehicle doors is characterized by comprising a car body with door one and door two disposed on one side of door one, and a car body with door two disposed on one side of door two. A locking assembly is disposed within the car body. Locking blocks are disposed on door one and door two. The locking assembly includes a connecting plate, a sliding shaft, and an actuating block distributed on both sides of the locking block. The actuating block has an inclined surface. The sliding shaft is connected to the actuating block. An opening is provided on the connecting plate for the movement of the sliding shaft. The connecting plate is fixed to the inner side of the car body away from door one or door two. A compression spring sleeved on the sliding shaft is disposed between the actuating block and the connecting plate.

[0006] The present invention further includes the following features: the connecting plate includes a first connecting plate and a second connecting plate; the sliding shaft includes a first sliding shaft and a second sliding shaft; and the actuating block includes a first actuating block and a second actuating block, with the first actuating block and the second actuating block distributed on both sides of the locking block.

[0007] The present invention is further provided that the locking block is provided with a mating hole, and the corresponding vehicle body is provided with a mating post for connecting to the mating hole. When the first door and the second door are opened under the action of the driving mechanism, the mating post is inserted into the mating hole.

[0008] The present invention further includes a rubber pad at one end of the insertion post.

[0009] The beneficial effects of this utility model are as follows: Two sets of connecting plates, sliding shafts, and actuating blocks are symmetrically arranged on both sides of the locking block to enhance locking stability. The locking block has interlocking holes, and corresponding interlocking posts are provided on the vehicle body. When the door is opened, the drive mechanism moves the door, causing the interlocking posts to insert into the interlocking holes, further securing the door position. Rubber pads are added to the ends of the interlocking posts to reduce insertion impact and noise. Attached Figure Description

[0012] The following will describe the implementation of this application in detail with reference to the embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0013] like Figure 1 As shown, this utility model is a locking mechanism for rail transit vehicle doors, including a first door 10, a second door 20, a car body 30 disposed on one side of the first door 10, and a car body 30 disposed on one side of the second door 20. A locking assembly is provided inside the car body 30. Locking blocks 40 are provided on the first door 10 and the second door 20. The locking assembly includes a connecting plate, a sliding shaft, and an actuating block distributed on both sides of the locking block 40. The actuating block has an inclined surface. The sliding shaft is connected to the actuating block. An opening is provided on the connecting plate for the movement of the sliding shaft. The connecting plate is fixed to the inner side of the car body 30 away from the first door 10 or the second door 20. A compression spring 70 sleeved on the sliding shaft is provided between the actuating block and the connecting plate.

[0014] In this embodiment, the connecting plate includes a first connecting plate 80 and a second connecting plate 90, the sliding shaft includes a first sliding shaft 100 and a second sliding shaft 110, and the actuating block includes a first actuating block and a second actuating block 60, which are distributed on both sides of the locking block 40.

[0015] Furthermore, the locking block 40 is provided with a mating hole 120, and the corresponding vehicle body 30 is provided with a mating post 130 for connecting to the mating hole 120. When the first door 10 and the second door 20 are opened under the action of the drive mechanism, the mating post 130 is inserted into the mating hole 120. A rubber pad 140 is provided at one end of the mating post 130.

[0016] In this invention, two sets of connecting plates, sliding shafts, and actuating blocks are symmetrically arranged on both sides of the locking block 40 to enhance locking stability. The locking block 40 has a mating hole 120, and the corresponding position on the vehicle body 30 has a mating post 130. When the door is opened, the drive mechanism moves the door, causing the mating post 130 to insert into the mating hole 120, further securing the door position. A rubber pad 140 is added to the end of the mating post 130 to reduce insertion impact and noise.
