Abstract
The utility model relates to a screw which comprises a screw head, a screw rod and a drill head arranged on the head part of the screw. The screw is characterized in that a thread is arranged on the external part of the screw. The screw can enter the internal part of an object by directly knocking of external force, or can be rotated by a driver, and can be unscrewed through the driver when requiring dismantling. The screw can prevent the bolt from automatically exiting in vibration.
Description
Technical field
The utility model relates to a kind of screw, relates in particular to a kind of fastening screw trip bolt of withdrawing from automatically of preventing.
Background technique
General common screw commonly used all is directly to comprise screw head and screw rod, and screw rod is linear; Need bigger pressure when the screw of this structure screws in object at the beginning, but it is enough promptly to exert all one's strength, if but the direction of exerting all one's strength can not be consistent with mind-set in the screw rod; It is crooked to be easy to cause screw to hammer into, and such working efficiency is lower, and operator are easy to fatigue; The straight line type screw of so directly knocking in is easy to when producing vibrations, and screw can withdraw from voluntarily.
Summary of the invention
But the utility model technical problem to be solved provides a kind of screw that strikes precession and prevent to withdraw from automatically.
The technological scheme that its technical problem of the utility model solution is taked is: a kind of screw, comprise the drill bit that has screw head, screw rod and be arranged on screw head, and said screw rod outside offers screw thread.
In order to increase the snap-in force of screw at interior of articles, said screw thread is a buttress thread form.
Further, said screw thread is the one-way type screw thread.
Further, said screw thread is the two screw threads of one-way type.
The beneficial effect of the utility model is: this screw can directly knock through external force and make it get into interior of articles, or through the bottle opener rotation, can screw out through bottle opener when needing dismounting, screw thread be provided with that screw withdraws from voluntarily in the time of preventing to shake.
Description of drawings
Fig. 1 is the schematic representation of the utility model structure;
Fig. 2 is the another kind of embodiment's of the utility model a schematic representation.
Among the figure: 1, screw head 2, screw rod 3, screw thread 4, drill bit.
Embodiment
A kind of screw shown in Figure 1 comprises the drill bit 4 that has screw head 1, screw rod 2 and be arranged on screw head, and said screw rod 2 outsides offer screw thread 3.
In order to increase the snap-in force of screw at interior of articles, said screw thread 3 is a buttress thread form.
Further, screw thread 3 as shown in Figure 2 is the one-way type screw thread.
Further, said screw thread 3 is the two screw threads of one-way type.
This screw can directly knock through external force and make it get into interior of articles, or through the bottle opener rotation, can screw out through bottle opener when needing dismounting, screw thread 3 be provided with that screw withdraws from voluntarily in the time of preventing to shake.
It is emphasized that: above only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technological scheme any simple modification, equivalent variations and modification that above embodiment did.
Claims (4)
