Description

Technical Field

[0001] This utility model belongs to the field of limiting screw technology, specifically relating to a limiting screw for selfie sticks. Background Technology

[0002] This utility model belongs to the field of limiting screw technology, specifically relating to a limiting screw for selfie sticks. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing a limiting screw for selfie sticks, which can improve the limiting effect of the phone frame on the selfie stick's floor stand, and can quickly adjust the limiting screw to quickly switch the phone frame between landscape and portrait modes.

[0004] This utility model is achieved through the following technical solution:

[0005] A limiting screw for a selfie stick includes a screw head and a screw rod. The screw rod includes a smooth screw rod portion and a threaded screw rod portion, which are coaxial. The outer diameter of the smooth screw rod portion is larger than the outer diameter of the threaded screw rod portion. The smooth screw rod portion is located between the screw head and the threaded screw rod portion. A wide flat truncated cone is provided between the smooth screw rod portion and the screw head. The outer diameter of the wide flat truncated cone is smaller than the outer diameter of the screw head. A screwdriver hole is provided in the middle of the screw head. An annular first chamfer is provided on the outer edge of the end face of the screw head away from the smooth screw rod portion. A thread is provided on the circumferential surface of the threaded screw rod portion.

[0006] Furthermore, the outer edge of the end face of the screw head near the smooth screw portion is provided with an annular second chamfer.

[0007] Furthermore, the screwdriver hole is in the shape of a regular hexagon.

[0008] Furthermore, the chamfer angle of the first chamfer is 45 degrees.

[0009] Furthermore, the outer diameter of the wide, flat truncated cone is 1 / 2 to 2 / 3 of the outer diameter of the screw head.

[0010] The beneficial effects of this utility model are as follows: The limiting screw designed for selfie sticks is used to lock the phone frame and the selfie stick's mounting bracket. It features a smooth screw portion and a threaded rod portion, with the outer diameter of the smooth screw portion being larger than that of the threaded rod portion. The smooth screw facilitates the rotation of the phone frame and also helps to withstand vibrations and impacts from the joint between the phone frame and the mounting bracket. A wide, flat truncated cone is designed to press the mounting bracket together, ensuring the phone frame and mounting bracket are tightly bound. The height of the wide, flat truncated cone allows for a certain gap between the screw head and the mounting bracket, facilitating finger rotation of the screw head. The outer diameter of the wide, flat truncated cone is smaller than the outer diameter of the screw head, utilizing the lever principle to easily tighten or loosen the screw head. This limiting screw of the utility model completes the fixation and limiting adjustment of the phone frame, is very convenient to operate, and provides good limiting effect and greater stability.

[0014] The present invention will be further illustrated below with reference to specific examples and accompanying drawings.

[0015] like Figure 1 , Figure 2As shown, a limiting screw for a selfie stick includes a screw head 1 and a screw rod. The screw rod includes a smooth screw rod portion 2 and a threaded screw rod portion 3. The smooth screw rod portion 2 and the threaded screw rod portion 3 are coaxial, and the outer diameter of the smooth screw rod portion 2 is larger than the outer diameter of the threaded screw rod portion 3. The outer diameter of the smooth screw rod portion 2 is 7.8 mm and its length is 8.7 mm. The outer diameter of the threaded screw rod portion 3 is 6 mm and its length is 15.6 mm. The smooth screw rod portion 2 is located between the screw head 1 and the threaded screw rod portion 3. A wide flat truncated cone 6 is provided between the smooth screw rod portion 2 and the screw head 1. The outer diameter of the wide flat truncated cone 6 is smaller than the outer diameter of the screw head 1. The outer diameter of the wide flat truncated cone 6 is 15 mm, the outer diameter of the screw head 1 is 28.8 mm, the height of the wide flat truncated cone 6 is 0.55 mm, and the height of the screw head 1 is 4 mm. A screwdriver hole 4 is provided in the middle of the screw head 1. The screwdriver hole 4 is a regular hexagon. The screw head 1 has an annular first chamfer 5 at the outer edge of its end face away from the smooth screw part 2, with a chamfer angle of 45 degrees. The threaded shank 3 has a thread 31 on its circumferential surface. The screw head 1 has an annular second chamfer 7 at the outer edge of its end face near the smooth screw part 2.

[0016] This utility model designs a limiting screw for selfie sticks, which is an integral structure. In use, the screw is passed through the mounting hole on the floor stand, and the threaded part 3 of the screw is threadedly connected to the mounting hole on the phone frame. The screw head 1 is rotated by hand, or a screwdriver is inserted into the screwdriver hole 4 of the screw head 1 to rotate it, thus fixing the phone frame and floor stand in place using this limiting screw. The outer diameter of the smooth screw part 2 is larger than the outer diameter of the threaded part 3; a thicker smooth screw part 2 is more effective at withstanding vibrations and impacts from the joint between the phone frame and the floor stand. The wide, flat, cylindrical platform 6 presses against the floor stand, pressing the phone frame and the floor stand together. The height of the platform 6 leaves a certain gap between the screw head 1 and the floor stand, allowing the finger to rotate the screw head 1. When rotating the screw head 1, the finger presses against the outer edge of the screw head 1. Since the outer diameter of the wide, flat, cylindrical platform 6 is smaller than the outer diameter of the screw head 1, leveraging the principle of leverage, the finger can apply force to press the phone frame and the floor stand together. Conversely, when it is necessary to rotate the phone frame, applying force with the finger can easily loosen the phone frame and the floor stand. Rotating the phone frame completes the switch between landscape and portrait modes. Then, the screw head 1 is tightened again. Because the floor stand itself is designed with an adjustable shooting tilt angle, the limiting screw of this invention is used to fix and limit the adjustment of the phone frame, making the operation very convenient, with good limiting effect and greater stability.

[0017] The above embodiments are merely preferred embodiments of the present utility model and are only used to explain the present utility model, not to limit the present utility model. Any changes, substitutions, combinations, simplifications, modifications, etc., made by those skilled in the art without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
