Abstract

The present invention discloses a safety hat being easy to adjust the tightness of a buckle belt. A first buckle belt is arranged on one side of a hat body of the safety hat. The first buckle belt is provided with a first fastener. The other end of the first buckle belt is connected to an elastomer. The elastomer is fixed inside the hat body. The first buckle belt can freely and straightly enter and come out of the internal and the external of the hat body. An abutting fastener is arranged on the first buckle belt which can release or fix the first fastener. Additionally, a second fastener is arranged on the other side of the hat body and can be buckled with the first fastener. When the first buckle belt passes over the lower jaw of a user and the first fastener and the second fastener are locked together, the elastomer is stretched, the first buckle belt is in the optimal tightness state by means of the restoring force of the elastomer, and the first fastener is fixed by the abutting fastener.

Description

Safety cap

Technical field

The present invention relates to a kind of safety cap, particularly a kind of safety cap with scalable cingulum.

Background technology

Present employed safety cap, comprise locomotive usefulness, bicycle, automobile-used, work usefulness, military, or motion is used or the like, its mainly the marginal ridge in the safety cap both sides be provided with the hatband of a pair of safety cap, then respectively be provided with the male and female fastener on the hatband, safety cap then utilizes male and female fastener and hatband and is fixed on the head, and since traditionally the hatband of this kind safety cap and fastener according to the demand of different end user's different lengths, and adjusted the position of fastener on hatband, except its adjustment mode comparatively bothers, adjust to the elasticity that just is fit to the user, then more difficult.So in the use, the in addition adjustment that has that the people just can be random is convenient to put on, and if transfer ground too tight, the user understands uncomfortable, if transfer too pine of ground, probably loses the meaning that wears a safety helmet again, especially by bike the time, incorrect and suitable the wearing of safety cap is breakneck in fact.

Summary of the invention

The specific embodiment

See also shown in Fig. 1～7, in the middle of first preferred embodiment of the present invention, a kind of safety cap consists predominantly of cap body 1, one first cingulum, 2, one second fasteners 3 and and supports the fastener 4 of pulling.

See also shown in Fig. 5～8, cap body 1 of the present invention as commercially available safety cap, it has first side 11 and second side 12, and has cushion 13 in inside, is made of expanded material.

See also shown in Fig. 1～3,5～6, first cingulum 2 of the present invention is set at first side 11 of cap body 1, its first end 21 has one

first fastener

23,22 at second end is connected with an elastomer 24, these elastomer 24 other ends then are fixed in the cap body 1, these 22 at first cingulum, 2 second ends can directly move to ground the inside and outside of cap body 1, and these first cingulum, 2 second ends can be subjected to this to support the fastener 4 of pulling to pulling.

2 of aforementioned this first cingulums include first end 21 and second end 22 that is Y-shaped, this second end 22 has two belt bodies 25, and be connected with elastomer 24 separately, respectively these elastomer 24 other ends then are fixed in the cap body 1 respectively, these 22 at first cingulum, 2 second ends can directly move to ground the inside and outside of cap body 1, and can be subjected to fasten and maintain static to the fastener 4 of pulling.

Aforesaid 4 of the fasteners of pulling that support have an entity plate 41 among the present invention, a pair of vertical with entity plate to cylinder 42, and be located in this to the clinching between

cylinder

43,22 at first cingulum, 2 second ends pass 43 of entity plate 41 and clinchings, when the clinching 43 of supporting the fastener 4 of pulling is positioned at the fastening position (referring to Fig. 5), first cingulum 2 maintains static, otherwise, when the off-position (referring to Fig. 6), first cingulum 2 can be free movable, so two ends 22 of first cingulum 2 can be freely in the 1 inside and outside turnover of safety cap cap body.And, in cap body 1, then be provided with elongated slot 44 corresponding to the moving position of first cingulum, 2 second ends 22 and elastomer 24, to be installed with first cingulum, 2 second ends 22 and elastomer 24.

In addition, support fastener 4 front ends of pulling at this and have a perforate 45 (referring to Fig. 6), by supporting the fastener 4 of pulling, and elastomer 24 front ends can't pass through this perforate 45 by perforate 45 for 2 of first cingulums, just do not cause elastomer 24 to be crossed, and influence the function of first cingulum 2 to the fastener 4 of pulling.Its method mainly contains:

1. the external diameter of elastomer 24 is greater than perforate 45;

2. elastomer 24 front ends have a limiter 46, and are for example shown in Figure 5, utilize rivet as limiter.

Moreover clinching 43 ends that support the fastener 4 of pulling are provided with tip or sawtooth portion 47 (referring to Fig. 2), make it have preferable fixed effect.

In an embodiment of the present invention, this aforesaid elastomer 24 is main application of rubber or the composite (seeing also shown in Figure 5) that contains rubber or uses helical spring (referring to Fig. 8).

See also shown in Fig. 4～8,3 of second fasteners of the present invention are set at second side 12 of cap body 1, and can interlock with

first fastener

23, and 3 of this second fasteners have 3 marginal ridge persons that are fixed on second side 12 of cap body 1 with second cingulum 31 of one second cingulum, 31, the second fasteners.

According to design of the present invention, when using safety cap of the present invention, as long as after putting on a safety helmet, and discharge to pulling fastener 4, with first cingulum 2 down (outward) pull out a distance, this moment, elastomer 24 was stretched, and first cingulum 2 is through behind user's the lower jaw, lets go after first fastener 23 and second fastener 3 are fastened, and allows elastomer 24 that first cingulum 2 is retracted, the tightness that first cingulum 2 is set at elastomer 24, the belt body 25 of second end 22 of first cingulum 2 will be fastened to the fastener 4 of pulling again, first cingulum 2 fixing position can be remained on, and when desiring to take off safety cap, then will discharge, remove first again to the fastener 4 of pulling, two fasteners get final product.The elasticity of safety cap cingulum of the present invention is preset in optimum value by elastomer 24, thus do not need to be adjusted again, very practical and make things convenient for.

In sum, only be preferable exemplifying embodiment of the present invention, be not in order to limit the present invention; All other do not break away from equivalence of the present invention to be modified or displacement, all should be contained in the scope of the invention.
