Description
Technical field
The utility model relates to side door lock under a kind of jump-proof type truck.
Background technology
As everyone knows, for making things convenient for cargo handling, all be provided with side door under the upper-turn-type on China overwhelming majority's railway universal gondola car and the special gondola.Be provided with side door lock down on the side door down, side door lock mainly is made up of parts such as hasp seat, downside door butt, hasp, bearing pins.Its locking principle is: earlier the downside door butt is pressed into the hasp seat, then rotates hasp, by external force hasp is fallen in the hasp seat draw-in groove, thereby make hasp compress the effect that the downside door butt reaches side door under the locking; When opening car door, thereby need hasp is rotated the unlatching car door in the opposite direction.This downside door latch structure simple operations is convenient, and still along with the raising of the railway freight-car speed of service and load-carrying, the following side door lock of this structure constantly vibrates because of train in train travelling process or is opened easily in last dumptruct operation switching process.The accident of following side door lock is opened and is not in time closed, and causes lorry to be scattered, to lose easily, influences the security of operation of train.Therefore a kind of bottom side door of gondola car lock with anti-jump function of design invention seems particularly necessary.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the utility model provides a kind of bottom side door of gondola car lock with anti-jump function, and it has advantages such as simple in structure, durable, reliable, safe.
The utility model is achieved through the following technical solutions:
Side door lock under a kind of jump-proof type truck, it is characterized in that: comprise the hasp seat, the hasp seat is provided with adjusting nut, dead bolt, be with back-moving spring on the dead bolt, one end of back-moving spring is fixed on the dead bolt, the other end is connected with adjusting nut, also is provided with hasp on the hasp seat, and hasp and hasp seat are rotationally connected.
Described dead bolt rear end is provided with draw ring, is convenient to the flexible of manual operation dead bolt.
Described dead bolt middle part is provided with boss, and an end of back-moving spring is fixed on the boss, is used to limit dead bolt overhang and location back-moving spring.
Described dead bolt can adopt the higher material of hardness to make, to improve its abrasion resistance.The effect of described back-moving spring is that the assurance dead bolt can be got back to the home position under the effect of back-moving spring.After assembling, have certain pre-compression force, guarantee to such an extent that dead bolt stretches out fully.Its surface can adopt coating to handle, to obtain higher rotproofness.
Described hasp is connected with the hasp seat by bolt, circle pad, nut, and hasp can rotate around bolt.
Described adjusting nut is connected with the hasp seat by screw thread, and the one end is a screw thread, is convenient to connect with following side door hasp seat; The other end is a hexagonal configuration, is convenient to install with instrument; Is through hole in the middle of the nut, for dead bolt flexible plays guide effect.Can regulate the pre-compression force of back-moving spring by nut.
Have dead bolt hole, rivet hole and bolt hole on the described hasp seat, under the described jump-proof type truck side door lock by rivet, be bolted on the open-top car bottom side rail.
During use, the hasp that at first turns clockwise, ready.Then the downside door butt is pressed into, at this moment is rotated counterclockwise hasp by manpower or external force, this moment, hasp contacted with dead bolt, and along with being rotated further of hasp, the elastic force that dead bolt overcomes back-moving spring is pressed in the dead bolt hole by hasp.Along with being rotated further of hasp, arrive the bottom, dead bolt has been avoided hasp, and dead bolt is returned to the home position under the effect of back-moving spring elastic force, and at this moment the hasp locking is finished, and dead bolt has blocked the clockwise trend of hasp, has played anti-jump function when no external force.Instantly side door needs open-type, by manpower or external force, can will descend side door lock to open along pointer rotation hasp.When locking or unlatching, also can spur draw ring and make the dead bolt withdrawal, to reduce the direct impact between dead bolt and hasp.
The utility model can prevent down effectively that the accident of side door lock opens, and is safe, good reliability.The utlity model has simple in structure that, advantage such as easy to use, safe and reliable.
