In actual work, sometimes it is necessary to perform screwing operations on thinner plates. In order to ensure the quality of the connection, the more turns of the screw teeth that are in direct contact with the plate, the stronger the connection between the screw and the plate. For smaller screws, the tapping speed will be very slow, resulting in low production efficiency. If you choose a thread with a larger pitch, although the speed is faster, it will easily occur because some tapping ends are thin plate parts. Silk phenomenon

The invention discloses a self-tapping and locking thin solid screw, which comprises a screw head, a stud and a locking washer. The bottom of the screw head is provided with a stud, and the stud also includes a locking section and a self-tapping Section, the self-tapping section is located at the right end of the locking section, and the bottom of the locking washer is provided with a helical elastic locking sleeve, and the elastic locking sleeve and the thread of the locking section cooperate with each other to lock the washer The piece is fixed on the bottom of the screw head. Compared with the prior art, the present invention makes the screw have the excellent performance of fast tapping and firm locking by setting the tapping section and the fastening section. In addition, the locking washer It can greatly improve the locking force of the fastening section, and ensure the stability and reliability of the screw connection for a long time.
Description
[Technical field] [0001] The present invention relates to the technical field of screws, particularly a technical field of self-tapping lock-type thin screws. 【Background technique】 [0002] The screw is a common fastener because it has a variety of domains that have a self-locking, simple manufacturing, a large amount of production, low cost, interchangeability, and other advantages and other benefits. The screw consists of two parts: the screw with the tip, wherein the screw portion is provided with an external thread. The screw rotation is rotated under the pressure of the pressure to the threaded bottom hole on the workpiece. And use the outer thread on the screw portion to achieve the self-locking of the screws in the axial direction. In actual work, sometimes the thin plates are screwed for screw operations, the more the number of ribs directly in contact with the sheet, but the connection between the screws and the sheets is, but if the teeth spacing The smaller screws wil...
