Detailed description of the invention
Below in conjunction with embodiment shown in the drawings, the utility model is further described.
Below about in the definition in direction, defined according to the direction observed in Fig. 2.
Safety cap as shown in Figure 1, mainly comprises cap shell 1, hat lining 2, rear hoop assembly 3 and lower cheekstrap 4.Hat lining 2 is arranged in cap shell 1, plays the effect of buffering; Rear hoop assembly 3 is arranged in cap shell 1 rotationally, makes safety cap can for the people of different head dummy; Lower cheekstrap 4 is connected with hat lining 2, makes safety cap more firm when wearing.
Wherein, rear hoop assembly 3 as shown in Figure 2, mainly comprises band 31, frenulum 32, supporting cover 33, first fastener 34, second fastener 35 and elastic component 36.One end of band 31 is connected with cap shell 1, is provided with the fixed leg 311 perpendicular with it in the middle part of it.Frenulum 32 has one at least, and it is provided with the opening 321 extended along its length, and the dual-side of opening 321 is provided with the latch 322 extended along frenulum 32 length direction; And its one end is inserted in band 31, and the other end is connected with cap shell 1, such frenulum 32 and head hoop 31 can relative motions, thus the degree of tightness realizing safety cap regulates; When frenulum 32 is one, this frenulum 32 to be located on fixed leg 311 and setting corresponding with band 31 by opening 321.Supporting cover 33 to be arranged on band 31 and to cover fixed leg 311, for supporting other parts of accommodation zone assembly 3; Its correspondence two side faces are respectively provided with a hole, for wearing a root system band 32.First fastener 34 is the sheet cylinder of a hard, it is connected with fixed leg 311 by screw rod, two sides are also had except its periphery, a side and frenulum 32 are close (called after medial surface), another side and frenulum 32 are away from (called after lateral surface), its medial surface is fixed with for being set in the holding section 342 be meshed on fixed leg 311 and with the latch 322 of frenulum 32, when the first fastener 34 rotates, latch 322 can be driven by the synchronous axial system of holding section 342, and then drive the movement of frenulum 32, thus realize the relative motion of frenulum 32 and band 31, its lateral surface is fixed with the first circumferential teeth 341 of formation one annular.Second fastener 35 is meshed with the first circumferential teeth 341 by the second circumferential teeth 351 of its side, can drive the first circumferential teeth 341 like this when the second fastener 35 rotates by the second circumferential teeth 351, and then drives the first fastener 34 synchronous axial system; Its another side (namely away from one end of the first fastener 34) is provided with a protuberance, and these protuberance central authorities are provided with non-circular second fixing hole.Elastic component 36 is a spring, and it is directly enclosed within the protuberance of the second fastener 35; Cover plate 37 then closing lid to contact with elastic component 36 on supporting cover 33, when elastic component 36 is in conventional sense, the second fastener 35 is meshed with the first fastener 34 under the effect of elastic component 36 (being meshed with the first circumferential teeth 341 by the second circumferential teeth 351); And when the second fastener 35 moves up due to External Force Acting, causing that elastic component 36 is stressed to be compressed, the second fastener 35 and the first fastener 34 are separated.Knob 38 to be arranged on cover plate 37 and to be fixedly connected by screw rod and the second fastener 35, this is because knob 38 is provided with a card column matched with the second fixing hole, when this card column is inserted in the second fixing hole, rotate the rotation that knob 38 can drive the second fastener 35, thus drive the rotation of the first fastener 34, finally realize the relative motion of frenulum 32 and band 31.
And when needing safety cap to take off from the head of user, knob 38 can be needed to pull out, the second coupled fastener 35 outwards movement can be driven like this, and then compression elastic piece 36 makes the second fastener 35 and the first fastener 34 be separated; Because frenulum 32 is also subject to outside pulling force, and there is not the effect of the second fastener 35, frenulum 32 can outwards move by band 31 relatively.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
