Description

neck collar

The present invention relates to a neck guard.

By the way, common neck braces can be used to fix the cervical spine of the injured to reduce the burden and avoid secondary injuries caused by the injured during activities. However, the relative positions of the neck brace and the chin rest cannot be adjusted according to the situation, resulting in the use of Therefore, an adjustable neck collar structure was born accordingly.

However, the adjustment structures of general adjustable neck braces are located on both sides. It is necessary to adjust the two adjustment structures at the same time to adjust or position the relative positions of the neck brace and the chin rest, and it is difficult to adjust the adjustment mechanisms on both sides to the same height position simultaneously. , and if the heights of the two sides of the neck collar are different, it is easy to cause secondary injuries.

Therefore, it is necessary to provide a novel and progressive neck guard to solve the above-mentioned problems.

The main purpose of the present invention is to provide a neck brace, which can smoothly adjust the collar to the most appropriate state through a single adjustment action.

To achieve the above purpose, the present invention provides a neck guard, which includes a neck cover, a chin rest, a connecting piece and an adjustment assembly.
