A fixing and adjusting structure of a monocular display on a helmet

Abstract

Provided is a fixing and adjusting structure of a monocular displayer on a helmet. A fixing seat is arranged on the helmet, a first limiting block is arranged above the fixing obliquely, and a second positioning block is arranged under the position obliquely opposite to a first positioning block. The monocular displayer is fixed with one end of a universal joint, the other end of the universal joint is fixed with one end of a radial arm, the other end of the radial arm is in rotary connection with the fixing seat through a rotary shaft, and the radial arm is located between a first fixing block and a second fixing block. A positioning block fixedly connected with the fixing seat is arranged above the rotary shaft, and the side wall of the positioning block is provided with an upper positioning groove and a lower positioning groove. A first limiting rod and a second limiting rod are arranged on the radial arm, the middle portions of the limiting rods are respectively and movably connected with the radial arm through hinge pins, one end of each of the limiting rods is a fixed end, the fixed ends of the limiting rods are connected through a spring, the other end of each of the limiting rods is a movable end, and the movable ends of the limiting rods are clamped on the side wall of the positioning block under the effect of the spring.

Description

technical field [0001] The invention relates to a helmet structure with a monocular display, in particular to a fixing and adjusting structure of the monocular display on the helmet. Background technique [0002] The digital individual helmet is generally fixed with a monocular display. During the use of the helmet, the position of the monocular display can be switched as needed, or the monocular display can be rotated downward to watch the content of the monocular display, or the monocular display can be rotated upward to restore the normal binocular vision. At present, there are mainly two ways to fix the monocular display on the helmet, one is fixed by a universal joint, one end of the universal joint is fixed on the helmet, and the other end of the universal joint is used to fix the monocular display. Adjust and lock the position of the monocular display through joints. The main problem with this method is that when moving the monocular display up and down, two hands a...

Problems solved by technology

In some occasions, such as when one hand holds a gun at the emergency scene, it is not convenient and safe to switch between the normal binocular field of view and watch the content of the monocular display when it is impossible to operate with both hands.

Another way is to fix the monocular display on the front of the helmet through a damping hinge, and switch to watch the content of the monocular display or the normal binocular field of view by turning up or down the monocular display. This method can be operated with one hand, but in the dark In some cases, flipping up the monocular display will leak screen fluorescence and expose its own existence, which is not conducive to concealment. In addition, the resistance of the damping hinge should not be mastered. If it is too large, it will not be easy to turn the monocular display. If it is too small, it will affect the fixation of the monocular display. Effect
