Description
Technical Field
The utility model relates to a rail vehicle keeper structure especially relates to a spacing keeper structure of one-way antigravity.
Background
On rail vehicle, lock, keeper are often arranged on the flap door as the locking structure that the door closed, and the lock is main locking structure, and the keeper is the secondary locking structure of supplementary lock function, because the keeper can not have lock core and key locking like the lock structure, often can be in the continuous operation of vehicle and vibration in-process, the clearance can constantly change between keeper bolt tongue and the hasp board, leads to the keeper not hard up, has the potential safety hazard. Meanwhile, when the door bolt is opened, the door bolt swings, and when the bolt tongue of the door bolt protrudes out of the door plate range, if the door is closed by mistake directly, the protruding bolt tongue collides with surrounding parts or equipment, so that the surrounding parts are damaged, and unnecessary maintenance is brought.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a novel antigravity limit door bolt, which limits a bolt tongue in a lock catch plate through the antigravity effect when the door bolt is in a closed state, and keeps the door bolt locked; when the door bolt is opened, the bolt tongue of the door bolt is limited in the direction parallel to the door panel through the limiting function, so that the protruding bolt tongue is prevented from being scraped and touched.
In order to achieve the purpose, the utility model provides a one-way antigravity limit door bolt structure,
including handle, bolt seat, bolt tongue, hasp board, bolt tongue one end and handle fixed connection, the hasp inboard is arranged in to the other end, its characterized in that: the handle is characterized in that a stop block is arranged on the lock catch plate relative to the bolt, a compression lock spring is arranged on the bolt seat, a limiting bead is arranged below the compression lock spring, a limiting groove is formed in the bolt connected with the end of the handle, the limiting bead is matched with the limiting groove and used for achieving limiting when the bolt is stably locked and unlocked, the weight of the handle is larger than that of the bolt, a moment rotating clockwise around a bolt shaft is formed when the bolt is closed, the stop block on the lock catch plate limits clockwise rotation of the bolt, and the bolt is pressed on the lock catch plate all the time and cannot loosen.
The included angle between the limiting grooves is 90 degrees relative to the center of the bolt shaft.
The limiting groove is V-shaped or arc-shaped, so that the limiting bead can be smoothly extruded out of the groove when the bolt tongue is about to rotate.
The bolt locking opening on the lock catch plate is wedge-shaped, so that the bolt can easily enter the locking opening when being locked.
The bolt seat is provided with a round hole, a limit screw is arranged in the round hole, and the compression lock spring is arranged below the limit screw.
The utility model discloses an open spacing recess on rotatory bolt, install the spacing pearl that has the compression locking spring on the bolt seat, when rotatory bolt is rotatory to the closed condition (when horizontal position promptly), spacing pearl slips into spacing recess, because the effect of the handle of dog and massive and the effect of locking spring, form a moment around bolt axle clockwise rotation, in order to guarantee that the bolt receives clockwise moment always, dog restriction keeper clockwise rotation this moment, the bolt will be compressed tightly on wedge hasp board always, can not appear becoming flexible, can prevent effectively that the bolt from droing because of vibration and action of gravity. Meanwhile, when the bolt tongue rotates anticlockwise and rotates to an opening state, the limiting ball enters the next groove to limit the bolt tongue to be in a vertical state, and the bolt tongue is prevented from swinging left and right when being opened. Traditional keeper structure among the present rail vehicle relatively, the utility model discloses a keeper structure not only can lock assigned position in vehicle operation vibration process, can lock assigned position when the keeper open mode simultaneously, guarantees that it can not produce unnecessary collision and scratch.
Drawings
FIG. 1 is a schematic view of a bolt configuration;
fig. 2 is a schematic cross-sectional view of a bolt construction.
Detailed Description
As shown in fig. 1 and 2, the whole keeper structure consists of a wedge-shaped lock catch plate 1, a keeper tongue 2 of the keeper, a keeper seat 3, a handle 4, a keeper shaft 5, a limit screw 6, a compression lock spring 7 and a limit bead 8. One end of the bolt tongue 2 is fixedly connected with the handle through the bolt shaft 5, the bolt tongue can rotate under the driving of the handle, and the wedge-shaped lock catch plate is convenient for the bolt tongue to easily enter the locking opening when being locked. The wedge-shaped lock catch plate 1 is provided with a stop block 9 opposite to the bolt, the bolt seat 3 is provided with a hole corresponding to the bolt shaft, a limit screw 6 is arranged in the hole, a compression lock spring 7 is connected below the limit screw, a limit bead 8 is arranged below the compression lock spring, a limit groove is arranged on the bolt fixed at one end of the bolt shaft, the limit bead is matched with the limit groove, and the included angle between the limit grooves is 90 degrees relative to the center of the bolt shaft. When the bolt tongue is in a locking state and an opening state, the bolt tongue is exactly in a horizontal position and a vertical position, and the limiting beads are also respectively arranged in the grooves in two different positions, so that the bolt tongue is stably locked and opened. The handle is lengthened, so that the weight of the handle is larger than that of the bolt tongue, when the bolt tongue is locked, a moment rotating clockwise around the bolt shaft is formed on the bolt tongue, the stop block on the lock catch plate limits the bolt tongue to rotate clockwise, and the bolt tongue is always pressed on the lock catch plate and cannot be loosened. The limiting groove is V-shaped or arc-shaped, so that the limiting bead can be smoothly extruded out of the groove when the bolt tongue is about to rotate.
Description of the bolt locking state: the handle 4 of the door bolt is in a horizontal position, the bolt tongue 2 is clamped in the wedge-shaped lock catch plate 1 and is pressed tightly by the stop block, meanwhile, the limiting bead 8 is clamped in the groove on the bolt tongue 2, the position is fixed, and the door bolt is locked.
Description of the bolt opening process: the keeper is opened from the locking position, need to rotate handle 4 anticlockwise, and bolt tongue 2 also anticlockwise rotates and breaks away from wedge hasp board 1, and compression locking spring 7 is compressed, and spacing pearl 8 is followed the recess on bolt tongue 2 and is followed the roll-off, and when handle 4 rotation angle reached 90, spacing pearl 8 gets into in the recess on bolt tongue 2 once more, and the bolt tongue can not the horizontal hunting at vertical position, and the keeper is opened the back and is fixed.
