Abstract
The invention relates to the technical field of screws, and discloses a 5G self-guiding adjusting screw which can solve the problems of material clamping, chip winding and positioning in an automatic assembly process and comprises a leading-in part, a middle part and a tail part; the lead-in part is tapped with lead-in threads; threads are tapped on the middle part; the tail is unthreaded; and a screwing notch is formed in the end face of the tail part. The large diameter shape of the lead-in thread on the lead-in part is triangular. The lead-in thread on the lead-in part is a round thread. The situations of inclination, scrap scraping, clamping and the like in the screw installation process are reduced through the lead-in part and the threads arranged on the lead-in part; the tail part has no thread, so that over-screwing can be avoided, and the invention has the advantages of quick installation, no need of preassembly, avoidance of scrap scraping, blockage and over-screwing.
Description
Technical Field
The invention relates to a screw, in particular to a 5G self-guiding adjusting screw.
Background
The current communication industry uses ordinary standard metric system threaded fastener, because of automatic comprehensive coverage, standard threaded fastener is in the automatic installation in-process problem as follows: 1. the installation inclination is not easy to generate in a guiding way, so that the clamping failure is caused; 2. aluminum scraps are wound and clamped tightly with an aluminum plate assembly, and scraps fall off; 3. the thread is not limited to cause overlong screwing.
Disclosure of Invention
The invention aims to provide a 5G self-guiding adjusting screw, which can solve the problems of material clamping, chip winding and positioning in the automatic assembly process.
The technical scheme adopted by the invention for solving the technical problems is as follows: A5G self-guiding adjusting screw comprises a leading-in part, a middle part and a tail part; the lead-in part is tapped with lead-in threads; threads are tapped on the middle part; the tail is unthreaded; and a screwing notch is formed in the end face of the tail part.
Further, the method comprises the following steps: the lead-in thread has 2-3 teeth.
Further, the method comprises the following steps: the large diameter shape of the lead-in thread on the lead-in part is triangular.
Further, the method comprises the following steps: the lead-in thread on the lead-in part is a round thread.
The invention has the beneficial effects that: the situations of inclination, scrap scraping, clamping and the like in the screw installation process are reduced through the lead-in part and the threads arranged on the lead-in part; the tail part has no thread, so that over-screwing can be avoided, and the invention has the advantages of quick installation, no need of preassembly, avoidance of scrap scraping, blockage and over-screwing.

Detailed Description
For the purpose of enhancing the understanding of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and examples, which are provided for the purpose of illustration only and are not intended to limit the scope of the present invention.
Example 1
As shown in fig. 1 and 2, the 5G self-guiding adjusting screw comprises a leading-in part 1, a middle part 2 and a tail part 3; the lead-in part 1 is provided with lead-in threads; threads are tapped on the middle part 2; the tail 3 is unthreaded; a screwing notch is formed in the end face of the tail part 3; the large diameter shape of the lead-in thread on the lead-in part 1 is triangle. The lead-in thread has 3 teeth; the thread pitch of the thread is 0.45mm, and the precision is 6 g; the screwing notch is in a straight shape, and the depth of the notch is 1.4 mm.
The leading-in screw thread is triangle thread structure, and the afterbody is threadless, can be used to take the diaphragm orifice of auto-lock structure, and anterior triangle-shaped screw thread is connected with the diaphragm orifice and is produced the moment of torsion, and triangle-shaped screw thread lock-in-process three point contact, and the atress is little, and leading-in is quick, reducible scraping bits phenomenon.
Example 2
As shown in fig. 1 and 3, the 5G self-guiding adjusting screw comprises a leading-in part 1, a middle part 2 and a tail part 3; the lead-in part 1 is provided with lead-in threads; the middle part 2 is provided with a mechanical thread; the tail 3 is unthreaded; a screwing notch is formed in the end face of the tail part 3; the lead-in thread on the lead-in part 1 is a round thread. The lead-in thread has 2 teeth; the pitch of the standard thread is 0.45mm, and the precision is 6 g; the screwing notch is in a hexagon socket star shape, and the depth of the notch is 1.8 mm.
The circular screw thread of the leading-in part 1 can be used for a common screw thread plate, the screw thread on the front circular screw thread and the plate is meshed, the screw can still be effectively led in the installation process, the circular screw thread can be more effectively led, the phenomenon that the screw thread is blocked due to incomplete screw threads in the leading-in process is avoided, and the phenomenon of scraping scraps can be reduced by the circular screw thread.
The above embodiments should not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent transformations fall within the protection scope of the present invention.
