Description

Technical Field

[0001] The utility model relates to the technical field of screws, in particular to an anti-deviation screw. Background Art

[0002] A screw is a common fastener used to connect two or more objects together. It typically consists of a head and a shaft with external threads. The screw is screwed into a material (such as wood, metal, or plastic) or a pre-drilled hole, using friction between its threads and the material to provide a secure hold.

[0003] When using self-tapping screws, there is no need to drill holes in advance. They use their own force to screw into the object. However, this self-tapping method is very likely to cause deviation when applying force, resulting in incomplete connection of materials and deviation at the top. For this reason, we propose an anti-drift screw. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-deviating screw to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an anti-drift screw, comprising a screw body, a first anti-drift mechanism and a connecting mechanism, the first anti-drift mechanism and the second anti-drift mechanism are arranged on the outside of the screw body, the first anti-drift mechanism and the second anti-drift mechanism are fitted with each other, the first anti-drift mechanism and the second anti-drift mechanism are connected by a connecting mechanism, and the tops of the first anti-drift mechanism and the second anti-drift mechanism are both provided with a supporting mechanism fitted with the screw body.

[0006] Furthermore, one side of the second anti-drift mechanism is provided with multiple groups of positioning grooves, one side of the first anti-drift mechanism is fixedly connected with a positioning block inserted into the positioning groove, the first anti-drift mechanism and the second anti-drift mechanism both include a protective shell and an external thread, and the interior of the protective shell is provided with an external thread that fits the thread position on the screw body.

[0007] Furthermore, the connecting mechanism includes a mounting seat, an adsorption sheet and a picking handle. The first anti-drift mechanism and the second anti-drift mechanism are both provided with a mounting seat. The mounting seat is adsorbed with an adsorption sheet made of magnetic material, and the adsorption sheet is fixedly mounted with a picking handle.

[0008] Furthermore, the support mechanism includes a first telescopic rod, a second telescopic rod, a support plate and a spring. The first telescopic rod and the second telescopic rod are slidably connected to the protective shell. The tops of the first telescopic rod and the second telescopic rod are fixedly connected to the support plate. A spring is fixedly installed on the top of the protective shell and located outside the first telescopic rod, and the top of the spring is connected to the support plate.

[0009] Furthermore, a spring washer is provided on the screw body, and a hexagonal screw hole is opened on the top of the screw body.

[0010] Furthermore, the protective shell, the mounting base, the second telescopic rod and the supporting plate are all made of rigid materials.

[0011] Compared with the prior art, the present invention has the following beneficial effects: the screw body and the hexagonal screw hole provided in the present invention can complete the self-tapping installation of the screw body, and before installation, the first anti-drift mechanism and the second anti-drift mechanism can be installed on the outside of the screw body, and then the first anti-drift mechanism and the second anti-drift mechanism are positioned using the connecting mechanism. At this time, the supporting mechanism contacts the screw body, and then the screw body can be rotated and lowered, so that the threaded body can be prevented from deviating during installation. After the screw body is continuously installed, the first anti-drift mechanism and the second anti-drift mechanism can be removed, which facilitates the installation and fixation of the screw body.

Then, when the screw body 1 continues to rotate and descend, it can be supported by the first telescopic rod 14 and the second telescopic rod 15 to ensure that the screw body 1 can descend stably and can be supported by the spring 17 when descending.

[0026] See also Figure 3 The screw body 1 is provided with a spring washer 18 , and the setting of the spring washer 18 can prevent the screw body 1 from loosening after the screw body 1 is installed.
