Problems solved by technology

However, the above two dispensing methods are not ideal, because the glue between the screw and the nut cannot completely and evenly fill the gap, resulting in inconsistent bite force, and ultimately cannot meet the requirements of military-standard laptops.
[0004] In view of this, it is necessary to provide a screw with a strong bite force to solve the above-mentioned problems that cannot meet the ultra-vibration requirements of military notebook computers due to insufficient bite force of the existing screws

Abstract

The invention discloses a dispensing screw. The dispensing screw comprises a screw cap, a screw body and at least one transverse runner, wherein a concave groove is formed in the upper end surface of the screw cap; a dispensing port is formed inside the concave groove; a dispensing runner is arranged on the screw cap along the dispensing port; the concave groove is used for twisting the dispensing screw; a main body of the screw body is cylindrical; the upper end of the screw body is connected with the lower end surface of the screw cap; a vertical runner is arranged inside the screw body; one end of the vertical runner is communicated with the upper end of the screw body; the communicated end of the vertical runner is connected with the dispensing runner; each transverse runner is arranged in the screw body and is perpendicular to the vertical runner; one end of each transverse runner is communicated with the vertical runner, and the other end of each transverse runner is communicated with the side surface of the screw body. According to the invention, the internal runners are dispensed, so that stronger engaging force can be provided, and requirements for super vibration of a military notebook computer are met.

Description

【Technical field】 [0001] The invention relates to a hardware connection workpiece, in particular to a screw capable of dispensing glue. 【Background technique】 [0002] Existing military-spec notebook computers can be widely used in harsh environments such as intense heat, severe cold, low air pressure and war due to their special purposes, and are mostly heavy. Due to the special environment used by military-spec laptops, there is a requirement for military-spec laptops to withstand super-vibration. Super-vibration has strict requirements on the bite force of screws, while general screw drop-resistant treatment cannot meet the requirements. After the product is assembled, it is necessary to further dispensing the screws. [0003] There are two methods for the existing dispensing process, one is dispensing before locking the screw, and the other is dispensing after locking the screw. However, the above two dispensing methods are not ideal, because the glue between the screw...
