Abstract

The utility model relates to a linkage structure of a sliding plug door, which comprises a first connecting rod connected with a handle and a driven rod connected with the first connecting rod; the head of the driven rod is provided with a groove; an electromagnet is arranged above the groove; the electromagnet is connected with the second connecting rod; the distance from the rear end face of the electromagnet head to the end face of the driven rod head is larger than the moving distance of the driven rod. The utility model discloses an increase driven lever length back, even passenger's maloperation can not take place because of the electro-magnet is blocked and lead to the unable trouble that can not open the door that resets of aggregate unit yet.

Description

Linkage device structure of sliding plug door

Technical Field

The utility model belongs to the technical field of the track traffic technique and specifically relates to a stopper sliding door aggregate unit structure.

Background

At present, the traditional linkage device applied to the double doors of the railway vehicle is easy to clamp the electromagnet when the passenger operates by mistake, so that the linkage device cannot reset and generates faults. If the passenger operates by mistake, the handle is pulled, the piece 1 and the piece 2 move 21.5cm to the left, and then the door opening request is pressed; at this moment, the head rod of the electromagnet is out of power (as shown in fig. 1), the distance from the head end face of the piece 2 to the rear end face of the head rod of the electromagnet is 20.3cm, but the piece 2 is withdrawn by 21.5cm at this moment, so that the front end face of the piece 2 is just behind the head of the electromagnet of the piece 3, under the condition, no matter how the handle is repeatedly pulled, the piece 2 cannot return to the normal position, the piece 1 and the piece 2 cannot drive the piece 4 to move through the piece 3, and finally, the unlocking cannot be realized, and the door cannot be opened.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the utility model provides a stopper sliding door aggregate unit structure, only need increase the slave bar head size, can realize preventing slow-witted function.

The utility model provides a technical scheme that its technical problem adopted is: a linkage structure of a sliding plug door comprises a first connecting rod connected with a handle and a driven rod connected with the first connecting rod; the head of the driven rod is provided with a groove; an electromagnet is arranged above the groove; the electromagnet is connected with the second connecting rod; the distance from the rear end face of the electromagnet head to the end face of the driven rod head is larger than the moving distance of the driven rod.

Furthermore, when the door is normally opened, the electromagnet of the utility model is powered off, and the head of the electromagnet falls down and is inserted into the groove; the first connecting rod drives the driven rod to move; the driven rod drives the second connecting rod to move through the electromagnet.

Furthermore, when the door is opened, the electromagnet is powered off, and the head of the electromagnet falls to the plane of the head of the driven rod.

The beneficial effects of the utility model are that, solved the defect that exists among the background art, through increasing the follower lever length after, even passenger's maloperation can not take place because of the electro-magnet is blocked and lead to the unable trouble that can not open the door that resets of aggregate unit yet.

Drawings

FIG. 1 is a schematic diagram of a prior art configuration;

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

in the figure: 1. a first connecting rod; 2. a driven lever; 3. an electromagnet; 4. a second connecting rod; 5. a driven rod head end face; 6. the back end surface of the electromagnet head; 7. a groove; 8. the driven rod head plane.

Detailed Description

The invention will now be described in further detail with reference to the drawings and preferred embodiments. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

A structure of a stopper door linkage as shown in fig. 2 comprises a first connecting rod 1 connected with a handle and a driven rod 2 connected with the first connecting rod 1; the head of the driven rod 2 is provided with a groove 7; an electromagnet 3 is arranged above the groove 7; the electromagnet 3 is connected with the second connecting rod 4.

When normally opening the door, according to the request earlier, 3 lose the electricity of electro-magnet, as shown in fig. 2, the head of electro-magnet 3 inserts in the recess 7 of driven lever 2, and passenger pulling handle drives head rod 1 and the motion of driven lever 2, and the recess 7 of driven lever 2 drives electro-magnet 3, and ferromagnetic iron 3 drives the motion of second connecting rod 4, and second connecting rod 4 drives the wire rope unblock, and the door is opened.

In this embodiment, after the length of the head of the driven rod 2 is increased by 4cm, the distance from the rear end face 6 of the head of the electromagnet to the end face 5 of the head of the driven rod is 24.3cm, which is greater than the moving distance 21.5cm of the driven rod 2. When a passenger operates by mistake, even if the driven rod 2 moves left by 21.5cm, the electromagnet 3 can only fall on the head plane 8 of the driven rod and can not be clamped on the end face of the head of the driven rod 2. After the handle is loosened by the passenger, the driven rod 2 can be normally reset, the passenger pulls the handle again, the driven rod 2 drives the electromagnet 3, and the electromagnet 3 drives the second connecting rod 4 to move, so that the door is unlocked and opened. Therefore, fool-proofing can be well achieved, the door can be opened no matter how the passenger operates, and false alarm faults are reduced.

While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
