Name: Method for making damping screws
Technical field:

The utility model relates to a screw, in particular to a damping screw, which is mainly applied to the shunt pressure relief of a pressure sensor.

Background Technology:

General common screw including screw head and diameter is less than the head of the neck, neck section is arranged at the lower part of the rod body, rod body is opened around the external thread, the general screw is composed of these three parts, its function is locked and fixed. In the use of the pressure sensor, the moment the pressure sensor opens the valve because the pressure value will be greater than the pressure value under normal circumstances, direct impact of the ceramic crystal sensor, easy to produce too much pressure and the ceramic crystal impact broken, so that the pressure sensor damage or measurement data is not accurate.

The invention content

The technical problem to be solved by the utility model is that the ceramic crystal is damaged due to the instantaneous excessive pressure of the existing pressure sensor.

The technical scheme of the utility model is a damping screw, which comprises a screw head, a neck contraction section and a rod body. The three parts are connected as a whole. The screw head is provided with at least one blind hole leading to the inner part of the rod body, and a lateral hole is provided on the side of the rod body, and the blind hole is communicated with the lateral hole on the side of the rod body.

The lateral hole on the side of the rod body of the utility model is a through hole and is located at the bottom of the rod body.

The optimal scheme of the utility model is that the screw head is provided with a word groove, and a blind hole is arranged in the middle of the word groove to the inside of the rod body, and the bottom of the rod body is provided with a through hole perpendicular to the rod body, and the blind hole is connected with the through hole.

When the utility model is used as a pressure sensor accessory, a screw hole is arranged on the ceramic crystal of the pressure sensor, and the damping screw device is arranged on the screw hole. The depth of the screw hole ensures that the lateral hole on the damping screw rod body is partially exposed, so that the pressure can be discharged from the lateral hole.

The utility model has not only locking and fixing functions but also shunt pressure relief functions to ensure the use of the pressure sensor and no new parts.
