Abstract

The utility model provides a rail vehicle is with manual sliding door stop gear which characterized in that: a limiting guide rail is connected to the bottom of the guide rail on the vehicle door, a plurality of limiting blocks are evenly arranged on the limiting guide rail, and the limiting blocks are matched with the lock tongues and used for limiting any position. In the door opening or closing process, the round lock tongue is shortened in the lock body through the rotation of the handle, when the door opening or closing action is completed, the handle is loosened at any position, the round lock tongue extends out and is blocked by the limiting block to generate a limiting effect, and the limiting precision of the door plate is controlled by changing the position of the limiting block. The utility model discloses a structural transformation based on current sliding door, limit guide is in the bottom of guide rail on the door, does not invade and accounts for the ascending space of double-deck next door width side, does not have the influence to the interface. Through the cooperation of the arc surface limiting block and the round spring bolt, the effective limiting of the car door when the car door is not opened in place or closed in place can be realized at any position, and the car door is prevented from freely sliding to injure passengers.

Description

Manual sliding door limiting mechanism for railway vehicle

Technical Field

The utility model relates to a manual sliding door of rail vehicle especially relates to limit structure of manual sliding door.

Background

The sliding door of the traditional motor train unit has two forms, namely a manual sliding door and an electric sliding door.

The electric sliding door is used as a functional part of equipment on a motor train unit, has two problems of machinery and electricity, is high in manufacturing cost, and has quite many faults caused by software logic problems and electrical hardware reliability problems.

The manual sliding door has the advantages of simple structure, low manufacturing cost and high reliability, and simultaneously, compared with the rotating shaft door, the manual sliding door does not occupy the space in a compartment and has many advantages. However, in the case of a large-opening manual sliding door, for example, a compartment sliding door of a sleeper compartment or a manual sliding door of a toilet for disabled people, when the door is not opened and closed, the door is in a free state, and at this time, if the vehicle is subjected to a traction or braking operation, the door may slide freely, which may injure a passenger.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a simple structure, novel manual sliding door stop gear that the reliability is high prevent that the vehicle from pulling or braking under the operating condition, and the door freely slides when the door does not reach to open and put in place and close and put in place, injures the passenger by a crashing object.

In order to achieve the above object, the utility model provides a rail vehicle is with manual sliding door stop gear which characterized in that: a limiting guide rail is connected to the bottom of the guide rail on the vehicle door, a plurality of limiting blocks are evenly arranged on the limiting guide rail, and the limiting blocks are matched with the lock tongues and used for limiting any position.

The limiting block is of a shaft structure with thick middle and thin two ends, and the spring bolt is a round spring bolt.

The limiting guide rail is of a channel steel structure with a downward opening, two side faces of the channel steel are provided with corresponding supporting holes, and two ends of a limiting block of the shaft structure penetrate through the supporting holes to be supported on the channel steel.

In the door opening or closing process, the round lock tongue is shortened in the lock body through the rotation of the handle, when the door opening or closing action is completed, the handle is loosened at any position, the round lock tongue extends out and is blocked by the limiting block to generate a limiting effect, and the limiting precision of the door plate is controlled by changing the position of the limiting block.

The utility model discloses a structural transformation based on current sliding door, limit guide is in the bottom of guide rail on the door, does not invade and accounts for the ascending space of double-deck next door width side, does not have the influence to the interface. Through the cooperation of the arc surface limiting block and the round spring bolt, the effective limiting of the car door when the car door is not opened in place or closed in place can be realized at any position, and the car door is prevented from freely sliding to injure passengers.

Drawings

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a partial schematic view of the present invention;

fig. 3 is a schematic view of the retracted state of the round bolt of the present invention;

fig. 4 is the schematic diagram of the extended state of the round bolt of the present invention.

Detailed Description

Referring to fig. 1 and 2, the utility model mainly comprises a limit guide rail 1, a limit block 2, a lock tongue 3, a lock body 4 and a handle 5, the limit guide rail is connected with the bottom of the guide rail on the original vehicle door, the limit guide rail is a channel steel structure with a downward opening, a plurality of limit blocks are evenly arranged on two side plates passing through channel steel, the limit blocks are in a shaft structure with two thin ends and a thick middle, a support hole is arranged on the limit guide rail, the thin parts at two ends of the shaft structure pass through the support hole to be supported on the limit guide rail, the upper part of the lock tongue is an arc surface, the arc surface lock tongue is shortened in the lock body through the rotation of the handle in the door opening or closing process, when the door opening or closing action is completed, the handle is loosened at any position, because the limit blocks are in the shaft structure, the arc surface lock tongue extends out to be matched with the arc surface of the shaft, the limiting precision of the door plate is controlled by changing the position of the limiting block.

Referring to fig. 3, in the process of opening or closing the door, the arc surface bolt 3 can freely slide after being shortened inside the lock body 4 by the rotation of the handle.

Referring to fig. 4, after the door is opened or closed, the handle is released, the arc surface lock tongue 3 extends out and is blocked by the limiting block 2 for limiting.
