Description

A kind of crash helmet and jockey thereof

Technical field:

The utility model relates to industry security cap and various forms of crash helmet, the jockey of especially a kind of chin strap and safety cap.

Background technology:

Existing national standard and Europe and the several criteria of other countries be to the requirement that is connected with of the chin strap of industry security cap and safety cap, and its specific requirement is to bear under the situation of pulling force of 150-250N the jockey of chin strap and safety cap at chin strap must throw off.The chin strap that safety cap is on the market joined is varied; But do not meet this requirement basically; What the overwhelming majority adopted is fixing or detachable connection; But under the situation of the pulling force of 150-250N or be that chin strap and safety cap cap shell can not be thrown off, cause user's neck to be reined in the generation life danger, or be lower than in power to throw off under the situation of 150N and cause that chin strap will lose efficacy under the normal operating position.The jockey of the existing a National standard of Mei Sian company; This device has designed a vulnerable area; This weak point branch breaks off under the situation of certain pulling force, and the shortcoming of doing like this is that chin strap just can not have been reused after vulnerable area broke off, and the user need buy new chin strap again; And the very easily damage in transit of such vulnerable area, produced a lot of customer complaints.

The another one situation is that the assembling of existing chin strap and safety cap is not very convenient; Cause operator or the end user of production line when installing or change chin strap, to produce trouble, thus in addition since assembling be inconvenient to cause the assembler time prolongation increased cost.

Summary of the invention:

To the problems referred to above, the utility model provides a kind of improved jockey and adopts the crash helmet of this device, is intended to reach following purpose: chin strap and safety cap cap shell must be thrown off between certain tensile region; Chin strap is reusable; Assembling and disassembling section are simple and convenient; Simple in structure, with low cost etc.

In order to realize the foregoing invention purpose, the utility model discloses a kind of jockey, it is characterized in that, comprising: a hook, said hook comprises a body of a hook portion and connection thereof, the end of said body offers a hole, is used to wear a ribbon.

Reasonable is that said hook further comprises: a shell fragment, the hook portion movable of one of which end and said hook fastens.

Reasonable is that the other end of said shell fragment is connected with the body of said hook.

Reasonable is that said hook adopts toughness such as polyformaldehyde, Merlon or polypropylene plastic material preferably.

The invention also discloses a kind of jockey, it is characterized in that, said jockey further comprises: a hook, and said hook comprises a body of a hook portion and connection thereof; One shell fragment, one of which end and said hook portion movable fasten; A junction, the body of said hook and the other end of said shell fragment are fixed on said connecting portion top, and the lower end of said connecting portion offers a hole, is used to wear a ribbon.

The invention also discloses a kind of helmet of using above-mentioned jockey, it is characterized in that, the lower edge of the said helmet offers plurality of opening, and the hook portion of said jockey is colluded and is located in the said perforate.

Description of drawings:

Below, with reference to accompanying drawing, for those skilled in the art that, from the detailed description to the utility model, above-mentioned and other purposes of the utility model, feature and advantage will be obvious.

Fig. 1 is a stereogram of using the helmet of the utility model first embodiment jockey;

Fig. 2 (a) and (b), (c) are left view, front view and the axonometric drawings of the utility model jockey first embodiment;

Fig. 3 (a) and Fig. 3 (b) are that jockey 3 is out of shape the sketch map of throwing off after receiving pulling force.

The specific embodiment:

First embodiment:

Fig. 2 (a) and (b), (c) are respectively the three-view diagrams of jockey 3, and Fig. 2 (a) is a left view, and Fig. 2 (b) is a front view, and Fig. 2 (c) is an axonometric drawing.

This jockey 3 comprises hook 20, and this hook 20 comprises a hook portion 21 and a body 22 that connects thereof; One end of shell fragment 23 and hook portion 21 movables fasten; The body 22 of hook 20 and the other end of shell fragment 23 are fixed on the top of connecting portion 25, and the lower end of connecting portion 25 offers a hole 26, is used to wear a ribbon 4.

Fig. 3 (a) and Fig. 3 (b) are that jockey 3 is out of shape the sketch map of throwing off after receiving pulling force.Wherein, the dotted portion representative is the structure in the hole 2 on the helmet 1.Fig. 3 (a) is the shape that normal operating condition does not receive the situation lower draw-bar 20 of big pulling force, and shell fragment 23 is arbitrarily deviate to establish after hanging on the hole 2 of the helmet 1 in order to prevent to link up with 20.23 between hook portion 21 and shell fragment 23, form big gap and then hook 20 is had living space and collude on the hole 2 thereby can push shrapnel with hand during assembling, unclamp hand shell fragment 23 after catching on and promptly reset, hook 20 just can not skid off hole 2; During assembling also can without hand push shrapnel 23 directly with shell fragment 23 by on the edge 8 in hole 2; Thereby also can form big gap between shell fragment 23 and the hook portion 21 can collude on the hole 2 hook portion 21; Hooking back shell fragment 23 can automatically reset; 20 of itself and hooks are just very close to each other, and whole hook 20 just can not arbitrarily be deviate from hole 2.Only need push shell fragment 23 again at 20 o'clock if will dismantle hook, hook 20 just can skid off hole 2.Fig. 3 (b) is the shape after hook 20 receives certain pulling force distortion; Link up with 20 existing very large deformation this moment; Between hook 20 and shell fragment 23, formed very big gap; The situation lower draw-bar 20 that further increases at pulling force can skid off hole 2 automatically, thereby has realized the purpose that chin strap and safety cap cap shell are thrown off.

Fig. 1 uses the stereogram of above-mentioned jockey 3 on the helmet 1.General lower jaw has two or four hooks, because structure is identical, and the place of here only having drawn.Porose 2 on the helmet 1 lower edge, jockey 3 colludes in hole 2 through hook portion 21, and ribbon 4 is sewn on this jockey 3 after passing the perforate 26 on the connecting portion 25 of these jockey 3 bottoms.

Second embodiment

Second kind of jockey of the utility model adopted simpler structure, and diagram is not arranged, and is the simplification on the above-mentioned first embodiment basis; Comprise: hook; This hook comprises a body of a hook portion and connection thereof, and the end of this body offers a hole, is used to wear a ribbon.The hook portion of this jockey is directly colluded in the hole 2 that is located at the helmet 1.

The 3rd embodiment

The 3rd embodiment is on the basis of second embodiment, has further increased by a shell fragment, and the hook portion movable of one of which end and said hook fastens, and the other end of shell fragment is connected with the body of hook.

The hook 20 of the jockey 3 of said structure adopts toughness such as polyformaldehyde, Merlon or polypropylene plastic material preferably; Because the characteristic of material itself; This jockey 3 is thrown off the whole shape in 2 backs, hole in distortion can return to original shape, thereby whole chin strap can be reused.

More than all embodiment only supply to explain the usefulness of the utility model; But not to the restriction of the utility model; The technical staff in relevant technologies field; Under the situation of spirit that does not break away from the utility model and scope, can also make various conversion or variation, so the category that all technical schemes that are equal to also should belong to the utility model should be limited each claim.
