Abstract
Description
Technical Field
[0001] The utility model relates to the field of rail transit trains, in particular to an isolation lock assembly. Background Art
[0002] Traditional isolation lock assemblies used in rail transit vehicle doors consist of a lock box, a rotating arm, a latch, and a torsion spring. The principle is that by rotating the rotating arm with a square key, the latch extends, thereby triggering the isolation lock switch assembly.
[0003] However, the isolation lock assembly of the prior art cannot isolate the left and right door leaves at the same time, and there is a risk of passenger misoperation. Therefore, it is necessary to develop a new isolation lock assembly to overcome the above problems. Utility Model Content
[0004] Purpose of the utility model: In view of the shortcomings and defects of the existing technology, the utility model provides an isolation lock assembly with the function of isolating the left and right door leaves at the same time; it is installed on the mechanism to prevent people from operating it incorrectly and prevent people from accidentally triggering the isolation switch.
[0005] Technical solution: The utility model is an isolation lock assembly, characterized in that it includes an isolation bolt, a compression spring, a connecting rod, a positioning shaft, a cam and a lock core connected in sequence; the cam is in contact with a switch, and the switch is located on the mounting base.
[0006] Wherein, the compression spring is wound around the outside of the isolation bolt.
[0007] Wherein, the installation base plate is provided with a plurality of installation holes.
[0008] Wherein, the isolation bolt is installed between the left door leaf connecting plate and the right door leaf connecting plate.
[0009] Wherein, the left door leaf connecting plate and the right door leaf connecting plate are respectively installed on the left door leaf and the right door leaf.
[0010] Wherein, the left door leaf and the right door leaf are installed on a rail transit train.
[0011] Beneficial Effects: Compared with existing technologies, this utility model has the following significant advantages: Unlike existing isolation lock assemblies, this utility model can simultaneously isolate both left and right door leaves, and the device is installed on the mechanism to prevent passengers from operating it incorrectly. The device realizes an integrated design of the isolation device and the isolation switch detection device, resulting in a simple structure, low cost, and high reliability.

DETAILED DESCRIPTION
[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0021] The isolation lock assembly of the present invention includes an isolation bolt 1, a compression spring 2, a connecting rod 3, a positioning shaft 8, a cam 4 and a lock core 7 connected in sequence; the cam 4 is in contact with a switch 6, and the switch 6 is located on a mounting base 5. The compression spring 2 is wound around the outside of the isolation bolt 1. The mounting base 5 is provided with a plurality of mounting holes. The isolation bolt 1 is installed between a left door leaf connecting plate 9 and a right door leaf connecting plate 10. The left door leaf connecting plate 9 and the right door leaf connecting plate 10 are respectively installed on a left door leaf 11 and a right door leaf 12. The left door leaf 11 and the right door leaf 12 are installed on a rail transit train.
[0022] During use, the lock core 7 is rotated by a specific key, and the lock core 7 pushes the isolation bolt 1 out through the connecting rod 3. In the closed state, the left door leaf connecting plate 9 and the right door leaf connecting plate 10 are in an overlapping state, and the isolation bolt 1 extends into the overlapping hole of the connecting plate to realize the isolation function. The utility model can isolate the left and right door leaves at the same time. The utility model realizes the limiting of the isolation position and the reset position through the pre-opened round waist hole on the mounting base plate 5 of the positioning shaft 8 installed on the cam 4. The utility model realizes the over-dead point lock through the positional relationship of the connecting rod 3 structure, realizes the self-locking function, and can only be restored by the key. The utility model uses the compression spring 2 to avoid the failure of the over-dead point structure under vibration conditions.
