The utility model aims at passing through screw hole erection equipment to current safe deposit box door plant key position, influence the problem of reliability, an improvement safe deposit box door plant reliability device is provided, the device sets up the plunger mounting hole through key position in the door plant inboard, weld the plunger in the stopper mounting hole at the door plant back, install key equipment through the plunger, the technology need not to change completely, production facility, the place is identical, the plunger of increase is the general piece of normal use, the cost is cheap, easily purchase, for carrying out the volume production fast and prepared, the reliability of safe deposit box door plant has been improved simultaneously.

In order to realize the technical purpose, the technical proposal of the utility model is that: the device for improving the reliability of the door plate of the safety box comprises the door plate and is characterized in that the door plate comprises an inner door plate, a plurality of plunger mounting holes are formed in the inner door plate, plungers are welded in the plunger mounting holes, threads are arranged on the inner sides of the plungers, and the blind ends of the plungers penetrate through the plunger mounting holes and extend out of the outer side of the inner door plate.

Furthermore, the door plate also comprises an outer door plate and a door protection plate arranged between the inner door plate and the outer door plate, and the door protection plate is arranged on the outer side of the inner door plate.

Furthermore, be provided with the plunger hole of stepping down on the door protective plate, the cecum of plunger can stretch into in the plunger hole of stepping down.

Further, the plunger inner diameter includes M3, M4, M5, M6.

The utility model has the advantages of it is following:

1) installing a plunger installation hole on the inner door plate, installing a plunger on the back of the inner door plate, welding and fixing the plunger, and increasing a plunger abdicating hole at the corresponding position of the door guard plate; in the whole door panel assembling process, the process is completely not required to be changed, production equipment and fields are completely the same, the added plunger is a commonly used universal part, the cost is low, the plunger is easy to purchase, and preparation is provided for rapid mass production;

2) the utility model uses the plunger to replace the existing threaded hole, thereby saving the tapping process of the threaded hole on the inner door plate, ensuring the quality of the threaded hole of the plunger more easily, preventing the occurrence of sliding teeth when the thread is returned to the threaded hole, and effectively improving the production efficiency; meanwhile, various devices are installed on the inner door plate.
