Description
Technical Field
[0001] The utility model belongs to the field of helmets, and particularly relates to a half-helmet with a rotatable wearing mode. Background Art
[0002] Basically, the existing half-helmets are all connected and fixed by soft straps, which is not very convenient to wear. In many cases, both hands are required to complete the wearing, and the wearing speed is relatively slow. In addition, for ordinary half-helmets, the lower part of the helmet on the top of the head is a soft strap and a plug-in type chuck. When wearing, in addition to putting it on the head, both hands are needed again to adjust, insert the plug-in type chuck, and then adjust the tightness to completely fasten and hold the lower jaw. In this way, it is difficult to operate with one hand. In reality, it is often seen that many people wearing ordinary half-helmets do not insert the plug-in type chuck. Without inserting the chuck to hold the lower jaw, the helmet is worn. Therefore, many people do not use the strap to fix the half-helmet when riding. Once an accident occurs, the half-helmet is very easy to fall off the head, and the safety factor is greatly reduced. Content of the Utility Model
[0003] Aiming at the above-mentioned existing technology, the purpose of the utility model is to provide a half-helmet that can be worn by rotating with one hand.
[0004] The technical solution of the utility model is realized as follows: A half-helmet with a rotatable wearing mode includes a helmet body, a rigid fixed helmet strap, and a rigid movable helmet strap. The rigid movable helmet strap and the rigid fixed helmet strap are made of a material with a certain rigidity. The rigid fixed helmet strap is fixed to the lower end of one side of the helmet body, and the lower end of the other side of the helmet body is provided with a rigid movable helmet strap. The rigid movable helmet strap is fixed to the lower end of the helmet body in a way that can rotate or move relative to the helmet body. The lower end of the rigid movable helmet strap and the lower end of the rigid fixed helmet strap can be locked together through a locking structure.
[0005] The beneficial effect of such a design is that the helmet can be worn with one hand. That is, first wear one side of the rigid fixed helmet strap to a suitable position on the human head, and then rotate the rigid movable helmet strap to the locking position with the rigid fixed helmet strap, so that the rigid movable helmet strap can be locked to...
[0006] Furthermore, the rigid movable helmet strap realizes rotation through a four-bar linkage structure. The four-bar linkage structure at least includes a first rod and a second rod. One end of the first rod is hinged to the upper end of the rigid movable helmet strap at a second axis, and the other end is hinged to the middle section of the helmet body at a first axis. One end of the second rod is hinged to the lower end of the helmet body at a third axis, and the other end is hinged to the middle section of the rigid movable helmet strap at a fourth axis. In this way, the rotation is more stable and can rotate along a certain arc.
[0007] Further, the four-bar linkage structure further includes a third rod and a fourth rod. The third rod and the first rod are located on both sides of the rigid movable helmet strap and have a hinge axis with the same axis. The fourth rod and the second rod are located on both sides of the rigid movable helmet strap and have a hinge axis with the same axis. The fourth rod and the second rod extend from the hinge position with the rigid movable helmet strap to both sides in a V-shape, so that the rotation is more firm and it is not easy to shake, etc., which may cause the rigid movable helmet strap and the rigid fixed helmet strap to fail to dock.
[0008] Further, the rigid fixed helmet strap is in a Y-shaped structure, and both ends of the upper side of the Y-shaped structure are fixed to the helmet body. In this way, when wearing, the squeezing of the ears can be reduced, making the wearing more comfortable.
[0009] Further, an arc-shaped track is provided on the helmet body and is matched with the chute provided on the rigid movable helmet strap, so that the rigid movable helmet strap can move along the arc-shaped track. In this way, it is convenient to operate with one hand and quickly move the rigid movable helmet strap.
[0010] Further, the outer sides of the rigid fixed helmet strap and the rigid movable helmet strap are wrapped with a flexible protective layer, so that the wearing is more comfortable, and the internal structure can also be blocked, making the half helmet more beautiful.
[0011] Further, a handle is provided on the outer side of the rigid fixed helmet strap, which is convenient for wearing and removing the helmet.
[0012] Further, the rigid fixed helmet strap is provided with an elastic lock pin and a lock groove, and the rigid movable helmet strap is provided with a lock head, and the lock head is provided with a lock hole that matches the elastic lock pin, so that when the lock head is inserted into the lock groove, the elastic lock pin can be inserted into the lock hole. In this way, the rigid movable helmet strap and the rigid fixed helmet strap can be stably locked together.
[0013] Further, the rigid fixed helmet strap is provided with a concave chin fixing part, so that the helmet can be worn more stably. BRIEF DESCRIPTION OF THE DRAWINGS
