Description

Door plate positioning mechanism and door plate and sliding plug door comprising same

Technical Field

The utility model relates to a positioning mechanism field, in particular to door plant and stopper sliding door that reach including this mechanism of door plant positioning mechanism.

Background

At present, bus door, subway door or high-speed railway door use the stopper sliding door usually, and stopper sliding door closure is good, and occupation space is few for whole motorcycle type elegant appearance, the security and the closure of stopper sliding door are directly influenced to the goodness of the lock of stopper sliding door, and in order to improve the security of stopper sliding door, the researcher in the field mainly puts the object of research in the structure of stopper sliding door lock.

The currently used sliding plug door lock structure is that when the vehicle door is closed, a guide wheel on the door lock is guided into the guide groove through a guide groove on the vehicle frame, the movement of the door lock is limited through the guide groove, and the door lock is fixed on the vehicle door, so that the movement of the vehicle door is limited, and the purpose of locking the door is achieved. On one hand, the door lock structure has great potential safety hazard, because the vehicle is in the driving process, the road surface is hollow, the guide wheel on the door lock can roll back and forth in the guide groove, so that the door is poor in sealing performance, and airflow can enter the vehicle from the door gap during high-speed operation, so that the riding experience of passengers is influenced; when the vibration is large, the phenomenon that the guide wheel returns and slides out from the original path in the guide groove can even occur, so that the vehicle door can be automatically opened, and great potential safety hazard exists. On the other hand, the guide wheel is generally only designed at the top of the door panel, and when the door is closed or opened, only the top of the door panel is stressed, so that the door is easy to close or open and is unstable due to uneven stress.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: to the problem that exists among the prior art, the utility model provides a door plant positioning mechanism reaches door plant and stopper sliding door including this mechanism adds door plant positioning mechanism in the door plant lower part of stopper sliding door for when closing the door or opening the door, the upper portion and the lower part of door plant can share the stress point, the switch is steady, play the positioning action to the door plant lower part, can prevent to a certain extent that the guide pulley is automatic to break away from the guide slot, reduce the damage of guide pulley, reduce and apply the power on the guide pulley when closing the door, save power, green.

The technical scheme is as follows: the utility model provides a door plate positioning mechanism, wherein a door frame positioning plate is fixed on a door frame of a door plate to be positioned, and a positioning groove block is fixed on the door frame positioning plate; one end of the rotating arm support is fixed on the driving rotating arm on one side of the door panel to be positioned, the other end of the rotating arm support is connected with a positioning roller, and the positioning roller is limited in a roller guide groove at the lower part of the door panel to be positioned; the door plate positioning plate is fixed on the door plate to be positioned, and the positioning convex block on the door plate positioning plate is matched with the positioning groove on the positioning groove block. Furthermore, the door plate positioning plate is provided with an interval adjusting groove, and the door plate positioning plate passes through the positioning groove block and the interval adjusting groove through a bolt and then is fixed on the door frame. When installing this door plant positioning mechanism on the stopper sliding door, if the interval between installation back positioning groove piece and the door plant locating plate is great or less, then the door is closed the door on the back door plant locating plate can't closely laminate with positioning groove or the too tight door plant positioning mechanism that damages of laminating, can't prevent effectively that the door plant from rocking, the bolt needs to be loosened this moment, adjust the position of positioning groove piece on the door plant locating plate through interval adjustment tank, so that positioning groove piece is close to or keeps away from the door plant locating plate, screw up the bolt until the two is suitable after the interval, the door is closed the back positioning lug and closely laminate with positioning groove again can't laminate too tightly just, reach the mesh that effectively prevents the door plant and rock.

Furthermore, a top thread is fixed on the door frame positioning plate through a top thread shaft, and the top thread is nested in the hollow inner wall at the bottom end of the driving rotating arm. The bottom end of the rotating arm is sleeved on a jackscrew on the doorframe positioning plate, so that the rotating arm and the doorframe positioning plate are of an integrated structure, and the structure is compact and reasonable.

Furthermore, the door plate positioning mechanism further comprises a locking block, and the door frame positioning plate sequentially penetrates through the positioning groove block, the interval adjusting groove and the locking block through bolts and is fixed on the door frame. The setting of latch segment makes the door frame locating plate can be fixed more firm with the door frame.

Preferably, the positioning groove is a long-strip-shaped V-shaped groove parallel to the ground, and correspondingly, the positioning bump is a long-strip-shaped triangular bump parallel to the ground. The positioning lug can be effectively positioned by matching the long-strip-shaped V-shaped groove and the long-strip-shaped triangular lug, so that the positioning lug can not move up and down in the vertical direction, and the aim of effectively preventing the door plate from shaking is fulfilled.

Furthermore, a limiting rod is fixed on the bottom surface of the rotating arm support. The setting of gag lever post makes the drive rocking arm can support the door frame locating plate when the door plant is opened, avoids the drive rocking arm because rotate the ultralimit and lead to door plant bottom and upper portion disequilibrium.

The utility model also provides a door plant, including foretell door plant positioning mechanism.

The utility model also provides a stopper sliding door, including foretell door plant positioning mechanism.

The working principle is as follows: this door plant positioning mechanism is when using, and is rotatory through power drive rocking arm, and the drive rocking arm drives rocking arm support rotation, and the location gyro wheel rolls in the gyro wheel guide slot of pending location door plant lower part under the drive of rocking arm support, and when the door plant was closed, the location lug just imbeds positioning groove in, realizes treating the location of fixing a position the door plant, prevents that the vehicle door plant from rocking when jolting.

Has the advantages that: add door plant positioning mechanism in the door plant lower part of sliding plug door, play the positioning action to the door plant lower part, when closing the door or opening the door, the guide pulley of the last location gyro wheel of door plant positioning mechanism and door plant top shares the stress point for the door switch is steady, can prevent to a certain extent that the guide pulley is automatic to break away from the guide slot, reduces the damage of guide pulley, reduces the power of applying on the guide pulley when closing the door, saves power, green.
