Description

Technical Field

[0001] The invention relates to the technical field of safety helmet hoop, and in particular to a positioning terminal shell integrated on the safety helmet hoop. Background Art

[0002] With the acceleration of industrial modernization, various large-scale engineering projects and complex working environments continue to emerge. The complexity of these workplaces makes it critical to quickly determine the location of people once an accident occurs. The traditional method of searching for people, which relies on manual shouting and regional inspections, is inefficient and wastes precious rescue time. For example, at a construction site, there are many floors and partitions that are intricate. When accidents such as fire and collapse occur, it is difficult for rescuers to quickly know the location of trapped people.

[0003] Traditional safety helmet positioning devices are often fixed to the surface of the safety helmet by external hanging or simple pasting. This method is not only easy to cause the positioning device to loosen, shift or even fall off due to collision, shaking, etc. during the operation of the personnel, affecting the accuracy and reliability of positioning, but also the safety helmets and positioning devices in the past are usually independent products. When workers need to adjust the safety helmet hoop to adapt to different head circumferences, the position and fixing status of the positioning terminal may be affected.

[0004] The emergency alarm function of existing positioning terminals usually needs to be triggered through menu operations or combination buttons on the terminal device. In an emergency, operators may need to spend time looking for the operation entrance of the alarm function. In an emergency, the lack of close coordination between the two may affect the rescue efficiency.

[0005] The waterproof and dustproof design of many existing helmet positioning terminal shells is simple, relying only on basic sealing gaskets or ordinary shell packaging. Traditional positioning terminals are often fixed by simple pasting or snapping. Such a design can easily lead to poor sealing, and water or dust can easily invade the interior of the device, affecting the normal operation of the circuit board. Summary of the invention

[0006] The purpose of the present invention is to solve the above problems and to propose a positioning terminal housing integrated on a safety helmet hoop.

In addition, the embedded installation of the shell and the first side wall and the embedded installation between the second side wall and the side wall of the third groove together build a strict waterproof and dustproof system, creating a safe and stable internal environment for the positioning terminal.

The limiting protrusions 531 are arranged counterclockwise along the inner side of the third groove 53 in a spiral shape, and the limiting protrusions 531 match the ratchet teeth 422 .

[0035] The protruding side wall of the third groove 53 can better fit with the second side wall 33 of the fixed cover 32, thereby improving the stability of the device. Moreover, the limiting protrusion 531 inside the third groove 53 can clamp the ratchet 422 to prevent the cap hoop from rebounding.

[0036] Preferably, a first circular hole 54 is provided inside the third groove 53 , and the first circular hole 54 matches the fixing column 34 .

[0037] Preferably, the end of the annular belt 51 is serrated, and the serrations at the end of the annular belt 51 mesh with the gear 41 .

[0039] The emergency button 11 is installed on the housing 1, and the internal structure of the button is closely matched with the key sensor 23 on the positioning device 21 inside the housing 1. The screw column 12 on the housing 1 and the first side wall 31 on the fixing cover 3 fix the positioning terminal 2 in the device to avoid displacement. The wearer rotates the shell 1, and the first notch 311 on the first side wall 31 clamps the screw column 12 on the inner side of the shell 1, and the shell 1 is connected and fixed to the fixing cover 3 by the screw. When the shell 1 rotates, it will drive the fixing cover 3 to rotate together, and the transmission member 4 is installed on the fixing column 34, and the limiting groove 421 on the transmission member 4 is meshed with the column 332 in the second side wall 33. Therefore, when the shell 1 and the fixing cover 3 rotate, the transmission member 4 is also driven to rotate, and the gear 41 at the other end of the transmission member 4 is meshed with the sawtooth at the end of the annular belt 52, thereby driving the movement of the annular belt 52 while the transmission member 4 rotates, so as to adjust the size of the cap hoop. When the rotation is completed, the ratchet 422 on the limiting plate 42 is stuck on the limiting protrusion 531 on the adjusting seat 51 to prevent the cap hoop from rebounding after the size is adjusted.
