Abstract
The utility model relates to a helmet and mask connection device and a helmet utilizing the same. The helmet and mask connection device comprises base plates for being fixed to the inner surfaces of two ends of the front side of the helmet. Each base plate is provided with an arc-shaped boss which is in sliding fit with an arc groove in one end of the mask. Mounting holes are respectively formed in two ends of each arc-shaped boss. An extending portion formed in the front of each base plate is thinner than the base plate and provided with a stepped hole. The mask retracts into the helmet completely when not used.
Description
Technical field
The utility model relates to jockey and the helmet of a kind of helmet and face shield, especially for jockey and the fire hat of fire hat.
Background technology
The face shield that existing fire hat is provided with mostly adopts external, and face shield rotates and is located at helmet outside, and in the time that fireman does not use face shield, face shield turns to helmet top outside, often can make at work face shield and crown portion object collision, thereby damages face shield; On the other hand, if Chinese patent literature number is the fire hat described in the document of CN202069013U, although its face shield rotates in the helmet, but face shield cannot all be taken in the helmet, in rotation process, can change with human face's spacing simultaneously, when face shield may overslaugh fireman during in some position work.
Utility model content
Technical problem to be solved in the utility model is to provide the jockey of a kind of helmet and face shield, and face shield can close in the helmet completely when not in use.
In order to solve the problems of the technologies described above, the utility model provides the jockey of a kind of helmet and face shield, it comprises: for fixing to the substrate of two ends, the front side medial surface of the helmet, this substrate is provided with arc boss, and this arc boss is suitable for being slidably matched with the arc groove of face shield one end; The two ends of this arc boss are respectively equipped with installing hole; The front side of substrate is provided with extension, and this extension is thinner than substrate, and extension is provided with stepped hole.
The utility model also provides a kind of helmet of the jockey that adopts the above-mentioned helmet and face shield, and described substrate is fixed on two ends, the front side medial surface of the helmet by installing hole, and the both sides of face shield are respectively equipped with and are suitable for the arc groove that is slidably matched with this arc boss; Extension is supported on the medial surface of face shield.
With respect to prior art, the technique effect the utlity model has is:
(1) helmet described in the utility model and face shield jockey, its face shield is slidably in helmet inner side, and in the time not using, face shield can be taken in inner helmet completely, damage when preventing that the helmet from falling or clashing into;
(2) fire hat in the utility model, face shield is free-extension in the helmet by arc boss and arc-shaped slot, can keep face shield and human face's spacing constant;
(3) extension is supported on the medial surface of face shield, can in face shield sliding process, support face shield, strengthens the intensity of face shield.
Brief description of the drawings
In order to clearly demonstrate innovative principle of the present utility model and the technical advantage than existing product thereof, by applying the limiting examples of described principle, possible embodiment is described by means of accompanying drawing below.In the drawings:
Fig. 1 is the structure chart of the helmet described in the utility model and face shield jockey and the helmet;
Fig. 2 is the back view of substrate described in the utility model.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the helmet 1 of the present invention comprises: face shield 2, arc groove 3, substrate 4, tapping screw 5.
Substrate 4 is fixed on two ends, the front side medial surface of the helmet 1 by two installing holes 42 on it and tapping screw 5, the back side that the back side of this substrate is provided with arc boss 41 and this arc boss 41 is adjacent to helmet medial surface, described two installing holes 42 are located at respectively the two ends of this arc boss 41, the both sides of face shield 2 are provided with and are suitable for the arc groove 3 that is slidably matched with described arc boss 41, the front side of substrate 4 is provided with extension 43, this extension 43 is thinner than substrate 4, this extension 43 is provided with stepped hole, and extension 43 is supported on the medial surface of face shield 2.
Can change the displacement of this face shield 2 with respect to the helmet 1 by the length that changes arc groove 3 and arc boss 41.
Obviously, above-described embodiment is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also giving exhaustive to all embodiments.And these belong to apparent variation that spirit of the present utility model extended out or variation still among protection domain of the present utility model.
