Description

Protective mask capable of being fixed on safety helmet Technical Field The utility model mainly relates to the technical field of construction safety protection tools, in particular to a protective mask which can be fixed on a helmet. Background The helmet is personal protective equipment for protecting the head, is commonly used in construction sites such as mines, construction sites and industrial manufacturing, and when in crushing, welding and the like, a protective mask is needed to be used for preventing broken stone, dust and metal scraps generated during operation from splashing to damage the face of a worker, so that the worker needs to be protected by the helmet and the protective mask in a matched mode. The traditional scheme is generally that the mask and the safety helmet are directly integrated into an integrated structure, the mask and the safety helmet cannot be detached and separated, and the burden of workers is increased to be inconvenient to use in occasions without using the mask. According to the above situation, the chinese patent technology with publication number CN217986798U sets up the cassette on both sides of the helmet, and the mask is plugged together with the cassette through the limiting plug board to perform the disassembly and assembly of the mask and the helmet, thereby improving the convenience of use. But its face guard needs to cooperate special safety helmet to use, and construction unit needs to purchase safety helmet and face guard simultaneously just can normal use, still leads to former safety helmet to appear idle easily when increasing purchase economic burden, causes the waste of resource easily, consequently needs a protective mask that can cooperate conventional safety helmet to install fixed use. ‌ A Disclosure of utility model The present utility model is directed to a protective mask that can be fastened to a helmet to solve the above-mentioned problems. The protective mask comprises two hanging rods, wherein one side end parts of the two hanging rods are fixedly provided with front protective covers, the tops of the front protective covers are provided with upper protective covers, a limiting cross beam is arranged between one ends of the two hanging rods, which are close to the front protective covers, and the hanging rods are also axially provided with clamping limiting parts and adsorption limiting parts, the two hanging rods are parallel to each other and are respectively positioned at the left side and the right side of the cap peak of the external safety cap when being worn, the clamping limiting parts and the adsorption limiting parts are inwards connected and fixed with the cap peak, and the limiting cross beam is perpendicular to the hanging rods and is erected at the top of the front end of the cap peak of the external safety cap when being worn. Preferably, the clamping limiting part comprises an elastic clip, the elastic clip is of a side-turning U-shaped structure, the opening position of the elastic clip is inwards and tends to be closed in the natural state, so that one side of the cap peak of the external safety helmet is clamped, the top and the bottom of the elastic clip are respectively provided with a hinge part, the hinge parts are hinged with a force application frame, and the elastic clip is clamped and then cooperates with a limiting beam to carry out three-point collaborative limiting on the vertical movement of the front protective cover.
