Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

Referring to fig. 1 to 7, the present embodiment provides a platform door lock structure, which includes a lock body disposed in a vertical frame 14 at one side of a door body 15, wherein the lock body includes a lock cylinder 1 and a top rod 2. The side of the door 15 facing the platform is defined as the front side and the side facing the track is defined as the back side.

The lock core 1 is pressed and fixed on the inner wall of the vertical frame 14 through a nut, and the vertical frame 14 is provided with a mounting opening 16 corresponding to the position of the lock core 1, so that the assembly is convenient.

The top of the vertical frame 14 is provided with a baffle 4, and the baffle 4 is provided with a limiting hole 5.

A handle cavity is arranged on the vertical frame 14 and on the back of the door body 15, a handle 3 is arranged in the handle cavity, one end of the lock cylinder 1 forms a lock hole 6 on the front of the door body 15, and the other end is connected with the handle 3. The keyhole 6 is specially arranged and is manually opened from the front only when a professional overhauls or under special conditions. The rear handle 3 is only manually opened by a professional on the rail vehicle in special cases.

The handle chamber caves in the mullion 14, sets up the opening on the mullion 14, installs baffle 7 in the opening, and lock core 1 passes baffle 7 and is connected with handle 3 through the screw, and it has a plurality of fixed edges 8 to extend on the baffle 7, and fixed edge 8 pastes and leans on the inner wall of mullion 14, fixes baffle 7 and mullion 14 through fixed edge 8. To improve the aesthetic appearance of the door body 15.

A spiral arm 9 extends out of the periphery of the lock cylinder 1 in a direction perpendicular to the axial direction of the lock cylinder, one end of the ejector rod 2 is hinged to the spiral arm 9, the other end of the ejector rod 2 extends out of the limiting hole 5 to form a lock tongue 10, a gasket 11 is arranged on the end, close to the lock tongue 10, of the ejector rod 2, a spring 12 is arranged between the gasket 11 and the baffle 4, and a pin 13 for limiting the gasket 11 downwards is arranged on the ejector rod 2. So as to buffer and reset.

The manual lock opening and closing is realized by manually driving the bolt 10 to stretch and retract by rotating the keyhole 6 or the handle 3 through a key, but the manual operation is only carried out under special conditions, and the normal opening and closing are automatically completed by an electric control system.
