Detailed Description
In order to facilitate the convenient opening of rail vehicle access door, the utility model provides a passageway lock suitable for rail vehicle, its structure please refer to fig. 1-2 and show, its structural component mainly has lock box 10, drive assembly and lock core subassembly 30 to constitute.
The lock case 10 is provided with a single-side opening and is box-shaped. The lock box 10 is mounted to the inside of the access door 40 by bolts 42 at the peripheral corners (shown in fig. 5). The bottom of the lock box 10 is transversely provided with a guide rod 11, the guide rod 11 is sleeved with a spring 24, and one end of the spring 24 is fixedly connected with the inner wall of the lock box.
The main function of the transmission assembly is to manually unlock the door lock from the inside of the access door. The transmission assembly comprises a horizontally disposed rack 20 which is parallel to and above the guide bar 11 in the lock case. One end of the bottom of the rack 20 is provided with a stopper 23, which is connected to the other end of the spring 24.
The tooth surface of the rack 20 is upward, and two sides of the rack respectively penetrate out of two side surfaces of the lock box to respectively form a pull rod 22 and a lock bolt 21. The handle 22 is manually operated to drive the bolt 21 to extend out of the lock box or retract into the lock box, thereby closing or opening the access door. Of course, under the action of the spring, the rack 20 can be driven to return to the initial position when the rack is not acted by external force.
The bolt 21 is of a conventional construction with one side plane and the other side curved, with the aim that the access door cannot be pushed open from the outside when the door is closed. If it is desired to unlock from the outside, the key is used to unlock the plug assembly 30.
Referring to fig. 3 and 4, the plug assembly 30 is composed of a clamping portion 31, a mounting portion 32, a gear 33 and a shaft 34, the mounting portion 32 of the plug assembly 30 is disposed in a mounting hole 41 (shown in fig. 5) of the access door when the plug assembly 30 is installed, a boss 37 is provided on one side of the mounting portion 32, and then the plug assembly 30 is rotatably clamped by the clamping portion 31 to be installed on the access door 40.
A shaft 34 is provided inside the mounting portion 32, which is supported for rotation by a bearing 35. One side (the direction of the outer side of the passage door) of the shaft 34 is provided with a square section, and the shaft 34 can be driven to rotate only by a square hole key. The other end of the shaft 34 is then assembled with the gear 33 by means of the retainer 36, and when the drive assembly and the plug assembly are assembled, the gear 33 is just engaged with the tooth surface on the rack 20. The shaft 34 is rotated by the rotation of the square hole key, so as to drive the gear 33 to rotate, thereby driving the rack 20 to horizontally move, and thus realizing the opening of the door lock.
When the lock is unlocked from the outer side of the access door, in order to control the rotating direction of the square hole key, when the spring in the lock box is designed to be in a free length, the stop block is abutted against the end part of the guide rod. In this case, the square hole key drives the shaft to rotate only in one direction, i.e., in a direction in which the door lock can be opened, and in the other direction, the key cannot be turned.
The assembly structure of the access door lock and the access door is shown in fig. 5, after assembly is completed, a worker positioned outside the access door needs to insert a square hole key into the lock cylinder assembly and rotate the key to open the access door if the access door needs to be opened. And the staff who is located the inside of access door, if need open the access door, only need to pull the pull rod gently, can open the access door. After the pull rod is released, the bolt returns to the original state (extending out of the lock case) under the action of the spring. The door lock can be closed by slightly pushing the door without using a key or pulling a pull rod when the access door is closed.
The foregoing is illustrative and explanatory of the present invention, and various modifications, additions and substitutions may be made by those skilled in the art without departing from the spirit and scope of the invention as defined in the following claims.
