Description

a helmet

technical field

The utility model belongs to the technical field of hat products and relates to a safety helmet.

Background technique

The safety helmet is a kind of protective equipment to prevent the head from being hurt by impact objects. It is usually composed of a cap shell, a cap lining, a lower chin strap and a rear hoop. The cap shell is hemispherical, firm and smooth, and has a certain degree of elasticity. The kinetic energy is mainly borne by the cap shell, and there is a certain space between the cap shell and the cap liner, which can buffer and disperse the impact force, thereby avoiding or reducing direct damage to the head. Therefore, safety helmets are widely used in metallurgical high-temperature workplaces, high-rise building construction, cold regions, and mines. However, in use, due to the large number of construction workers, the existing safety helmets are difficult to identify, and people are easy to take the wrong or lose the hats, and it is difficult for the on-site management personnel to identify each construction worker.

my country's patent CN 2894328Y discloses a kind of safety helmet with a work permit card, which is to establish a plastic film bag at the forehead position of the safety helmet, and a paper work permit card can be placed in it. This can avoid the inconvenience of workers wearing a work card to work on their chests, and can enable site managers to easily distinguish the specific identity of each worker.

However, the above-mentioned patent does not disclose how the plastic film bag is arranged on the safety helmet. As can be seen from the accompanying drawings of the above-mentioned patent, there is no connection structure between the plastic film bag and the safety helmet. In the pasting method is usually used. However, since helmets are usually used in cold areas, construction sites with a lot of dust and impurities, or mines with high humidity and other places with harsh environments, the stickiness of plastic film bags on the helmet is greatly affected by temperature, humidity, etc. , If the temperature is too low, the glue will be frostbitten, causing it to be insecure and warped, and if the humidity is too high, the viscosity will also be reduced, which will cause the plastic film bag to be insecure.

Contents of the invention

The purpose of this utility model is to provide a safety helmet for the above-mentioned problems existing in the existing technology. Humidity effects, improve the connection stability between the shell and the helmet.

The purpose of this utility model can be achieved through the following technical solutions:

A safety cap, comprising a cap body and a cover body located on the outer surface of the cap body, characterized in that the cover body is fixed on the outer surface of the cap body through a mechanical connection, and when the cover body and the cap body After the connection, an inner cavity is formed between the two, and the outer surface of the cover also has a visible structure for observing the inner cavity.

The cover in the utility model is fixed on the outer surface of the cap through a mechanical connection, so that the connection between the two is not affected by temperature and humidity, and the connection between the two is stable. For the work card, the construction personnel can observe the card in the inner cavity through the visible structure on the cover, so as to identify their own safety helmet and avoid mistaking or losing it.

In the above-mentioned safety helmet, several sub-buckles with protrusions are fixed on the cover body, and several female buttons are fixed on the outer surface of the cap, and the female buttons are provided with The recessed part where the protrusion engages with each other. The buckle is designed as a buckle, so that the assembly and disassembly between the cover body and the cap body are convenient, and the aesthetics of the safety helmet is increased.

In the above-mentioned safety cap, as another solution, the cover body is provided with several through holes, and the outer surface of the cap body has several threaded holes, and the inside of the through holes and the threaded holes At the same time, a screw capable of fixing the cover body on the cap body is pierced. Compared with snap buttons, the screw connection makes the connection between the cover body and the cap body more stable and reliable.

In the aforementioned safety helmet, the cover body is a transparent plastic film, and the visible structure is the middle part of the plastic film. Because the outer surface of the safety helmet has a certain curvature, and the plastic film is flexible and can fit the outer surface of the cap body, the production cost is relatively low, and the plastic film is transparent so that the interior of the above-mentioned inner cavity can be seen, and a card is arranged in the inner cavity It is convenient for users to observe and identify.

In the aforementioned safety helmet, the plastic film is rectangular, and a semicircular opening is opened on one side of the plastic film. A semicircular opening is provided to facilitate loading and unloading of work cards.

In the above safety helmet, as another solution, the cover body is a cover plate, and the visible structure includes several through holes opened on the surface of the cover plate. Compared with the plastic film, the cover plate is firmer, and a through hole is opened on the cover plate, so that construction personnel can observe the work cards in the inner cavity, thereby facilitating construction personnel to identify them.

Compared with the prior art, the utility model has the following advantages:

1. The connection between the cover body and the cap body in the utility model is not affected by temperature and humidity, and the connection stability between the two is good.

2. In the utility model, the cover body and the cap body are engaged with each other through snap-in buckles, which is convenient to assemble and disassemble and has good aesthetics.

3. The cover body in the utility model is a transparent plastic film, and the production cost of the plastic film is relatively low, which is suitable for mass production.

4. There is a semicircular opening on one side of the plastic film, which is convenient for loading and unloading work cards.
