The hasp seat comprises a plate-type matrix, and a first strut and a second strut which are separated from each other and extended along the direction perpendicular to the matrix. One end of the buckle iron is connected with the first strut pivot, and the other free end is connected with the second strut in a detachable manner; a self-locking device is also arranged on the second strut to lock the free end of the buckle iron together with the second strut. The double self-locking hasp has the advantages of nice and elegant appearance, easy operation, high safety and reliability.
Description
Technical field
The utility model relates to a kind of open-top car door hasp, especially a kind of open-top car side door hasp of railway truck.
Background technology
At present, the bottom side door of gondola car hasp of the existing railway truck of China, employing be simple hasp returning buckle retaining mode.This button retaining mode is in the lorry operational process, hasp is easy to shake tripping, side door is opened under causing, downside goalkeeper after opening surpasses vehicle gauge of the locomotive, can clash into railways train operation equipment, adjacent line rolling stock, wound railroader along the line, thereby cause train operation accident and personal injury, cause goods simultaneously and leak, jeopardize traffic safety and loss of goods.In order to reinforce its safety, take at present in the Freight Transport process and the cargo loading back that finishes ties up bonding with iron wire, so both increased field worker labour intensity, making the switch gate pole again, it is loaded down with trivial details, waste time and energy, and waste material, contaminated environment.Same this mode, executing when repairing at lorry has increased working strength of workers, has prolonged when repairing, and makes the degree of utilization of lorry descend.
Summary of the invention
The purpose of this utility model is the above-mentioned defective at prior art, provides a kind of simple to operation, the double self locking hasp that safety is firm.
The utility model for achieving the above object, the technical scheme that adopts is: a kind of double self locking hasp, comprise hasp seat and button iron, described hasp seat comprises template matrix and two first pillar and second pillars that separate mutually that extend perpendicular to described matrix, described button iron one end is connected with described first buttress pivot, departing and described second pillar of another free end is connected, and it is characterized in that: also being provided with on described second pillar can be with the self-locking device of described button iron free end and the locking of described second pillar.
Double self locking hasp of the present utility model is owing to adopted self-locking device, automatically hasp seat and button iron is locked, improve the fixing that side door is closed under the lorry greatly, deduct the loaded down with trivial details operation of iron wire binding, both saved a large amount of iron wires, alleviated working strength of workers again, made that the lorry profile is more attractive in appearance.

The tool embodiment
Fig. 1 is to shown in Figure 4, and the double self locking hasp among the utility model embodiment comprises hasp seat 1, with hasp seat 1 one end pivoting bonded assembly button iron 2, and connects hasp seat 1 and the self-locking device 3 of detaining iron 2.Hasp seat 1 comprises template matrix 4 and two first pillar 5 and second pillars 6 that separate mutually that extend perpendicular to matrix 4, wherein matrix 4 is provided with through hole 7, one nuts (not shown) perpendicular to matrix 4 and passes this installation through hole the double self locking hasp is captiveed joint with car body 8; First pillar 5 is provided with perpendicular to the through hole 9 of matrix 4 and first transverse groove 10 that is communicated with this through hole 9; Second pillar 6 is provided with perpendicular to the accepting hole 11 of matrix 4 and second transverse groove 12 that is communicated with this accepting hole 11.Button iron 2 one ends are housed in first transverse groove 10 and are provided with through hole 13, one nuts 14 and pass matrix respectively and through hole 9 is installed and is detained Tie Tong hole 13 and captive joint with car body 8.Self-locking device 3 comprises that a button 15, one lock pins 16, one springs 17 accommodate in the accepting hole 11 of second pillar 6, and button 15 can be by being threaded with lock pin 16.Lock pin 16 comprises a special-shaped portion vertically at least, is set to square cylindricality as lock pin 16 1 ends in the present embodiment, and the other end is set to the cylindrical projection 18 that has.Button iron 2 other ends are provided with and the corresponding mounting hole of lock pin abnormity portion shape (not shown).
Double self locking hasp of the present utility model embeds button 1 with following side door left and right door bolt and buckle in the embedding chamber between the iron 2 in use, and certain button iron of the present utility model 2 middle parts can also be set to U-shaped in order to increase embedding cavity space.Returning buckle iron 2 makes its free end enter second transverse groove 12 of second pillar 6, and lock pin 16 special-shaped portions insert under spring 17 effects and buckle in the mounting hole of iron 2, thereby it is locked with button 1 to detain iron 2, and it can't be opened voluntarily.When opening, pressing button 15 overcomes spring 17 elastic force makes lock pin 16 special-shaped portions break away from the mounting hole of buckleing iron 2, and detain iron 1 and just can freely take off this moment.
Double self locking hasp of the present utility model has adopted self-locking device, and is automatically that hasp seat and button iron is locked, simple to operate, improves the fixing that side door is closed under the lorry greatly.
