Description
Technical field
The utility model relates to a kind of door lock, relates in particular to a kind of door lock of open-top car car door.The utility model also relates to a kind of open-top car car door and open-top car with above-mentioned door lock simultaneously.
Background technology
Open-top car is a kind of Railway Freight Transportation vehicle, is mainly used in shipment coal, ore, building materials, coke, timber and other items.Open-top car can also adapt to mechanization car unloading operations such as dumptruct except that satisfying artificial loading and unloading mostly.Have car door on the compartment of open-top car, on the door-plate of this car door locking device is installed.
As shown in Figure 1, existing open-top car car door comprises left-hand door plate 10a and right door-plate 9a.During closing of the door, the edge, left side of described right door-plate 9a is pressed in the right edge of described left-hand door plate 10a along last, and left-hand door plate 10a and right door-plate 9a outwards open, and can realize locking to the open-top car car door by the right door-plate 9a of door lock assembly locking.
The open-top car door lock comprises locking bar 1a, handgrip 5a and locked groove 4a in the prior art, the end of described handgrip 5a is by the flexible connection of the left hand edge of the first bearing pin 6a and right door-plate 9a, the middle part of described handgrip 5a is connected with the top movable of described locking bar 1a by the second bearing pin 2a, the lower vertical of described locking bar 1a is inserted in the locked groove 4a, and can slide along the locked groove of locked groove 4a, the head of described locking bar 1a vertically is inserted in the lockhole 3a of Xiamen beam 11a.
When upwards moving handgrip 5a, handgrip 5a upwards rotates around the described first bearing pin 6a, and handgrip 5a upwards rotates around the described second bearing pin 2a simultaneously, and then can drive locking bar 1a motion vertically upward in locked groove 4a, thereby the head of locking bar 1a is extracted from described lockhole 3a, right door-plate 9a is opened; When moving handgrip 5a downwards, handgrip 5a rotates around the first bearing pin 6a, and handgrip 5a rotates around the second bearing pin 2a simultaneously, and then can drive locking bar 1a motion vertically downward in locked groove 4a, the head of locking bar 1a inserts among the described lockhole 3a, with right door-plate 9a locking.
But, in open-top car operation or when last dumptruct was unloaded, the open-top car car body can produce vibrations, locking bar 1a and handgrip 5a are easy to generate and beat, and cause locking bar 1a to break away from lockhole 3a, thereby cause right door-plate 9a locking to lose efficacy, therefore, the locking performance of above-mentioned open-top car door lock is unreliable.
The utility model content
At above-mentioned defective, the technical problem of solution of the present utility model is to provide a kind of door lock, and this door lock has good anti-jump performance, locking dependable performance.
The utility model provides a kind of door lock, be used for locking open-top car car door, comprise the bearing that is fixed on Xiamen beam outer wall, this bearing comprises the locating shaft with Liangping, described Xiamen row, described door lock also comprises bolt, and the length direction of described bolt has the strip hole of deflection one end, and described locating shaft passes described strip hole, this strip hole is divided into three sections along its length with described bolt, specifically comprise short first section, have an interlude in strip hole and long second section;
Described locating shaft passes the strip hole of described bolt, and described first section length is less than the axis of the described locating shaft distance to described Xiamen beam outer wall, and described second section length is greater than the axis of the described locating shaft distance to the door-plate lower limb; Described second section when being at the highest notch, this door lock is in locking states.
Preferably, described second section has bending part.
Preferably, described bending part and described interlude are greater than 120 ° of obtuse angles less than 150 °.
Preferably, described bending part and described interlude are rectangular.
Preferably, has through hole on described second section.
Preferably, have cylindrical or rectangular block on the door-plate directly over the described bolt, this block is a little more than the bolt top that is in locking states.
Preferably, described bearing is the groove shaped structure, and described bolt is installed in the groove of described bearing.
The utility model also provides a kind of open-top car car door, has left-hand door plate and right door-plate, and the edge of described left-hand door plate and right door-plate flexibly connects with curb girder respectively, and this open-top car car door is equipped with above-mentioned the utility model content and the described door lock of preferred embodiment.
The utility model also provides a kind of open-top car, and this open-top car is equipped with above-mentioned the utility model content and the described door lock of preferred embodiment.
