Description
Technical field
The utility model relates to fastening with built-in hat lining of a kind of safety cap and regulates linkage structure, belongs to labor safety protection articles for use technical field.
Background technology
Safety cap is a kind of common labor safety protection articles for use, correctly wears safety cap and can effectively take precautions against the injury of burst accident to wearers head.At present, the safety cap of market sale by the hard cap shell of scale, can regulate soft hat lining and the hatband of wearing size and constitute.The hat lining of prior art is in advance by wearer's head circumference size adjustment, and each adjusting all will can transfer to suitable dimensions through trying on repeatedly.Although the safety cap of prior art has the hat lining adjustable structure, it is convenient inadequately to regulate, and the elasticity adjusting is definite by position limiting structure, is difficult to transfer to the optimum position.
The utility model content
The utility model is primarily aimed at the deficiencies in the prior art, proposes a kind of adjustment structure safety cap simple, easy to use and fastens and built-in hat lining adjusting linkage structure.This structure directly links hat lining by wearer's head circumference size adjustment when fastening.
The utility model is achieved through the following technical solutions technical goal.
Safety cap is fastened with built-in hat lining and is regulated linkage structure, and it is made up of cap shell, hat lining, hatband, guide groove and guide rod.Described hat lining is semicircle flexible body member.Its improvements are: base, described hat lining both sides is provided with guide groove and the guide rod that is the gap fit.Described hatband is Y-shaped, up two ends branch be located at guide groove and the guide rod held about the hat lining base and be hinged respectively, hatband down placed in the middle is provided with and opposite side hatband buckle structure mutually.
The contraction of hat lining and amplification determine that by guide groove and guide rod sleeving fastening degree the sleeving fastening degree of guide groove and guide rod is controlled by the fastening degree of hatband.The cross section of guide groove and guide rod is combined into common structure with rectangular sleeve, also can be made into cross section and is semicircle or circular shrink-fit structure.
The utility model compared with prior art has following good effect:
1, fasten interlock hat lining size adjustment by hatband, it is that the hat lining adjusting puts in place that hatband is fastened, and hatband is not fastened hat lining and can not be cooperated with wearers head, and it is not the hatband phenomenon that this structure is avoided the safe wearing cap, improves the use value of safety cap;
2, linkage structure is simple, and is easy to manufacture;
3, change structural constraint into by the system constraint, reduce management cost.
Description of drawings
Fig. 1 is the situation schematic diagram of the utility model when not fastening hatband.
Fig. 2 is the situation schematic diagram of the utility model when fastening hatband.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Fig. 1 is the utility model situation schematic diagram when not fastening hatband, and it is made up of cap shell 1, hat lining 2, hatband 3, guide groove 4 and guide rod 5.What base, described hat lining 2 both sides left end connected is guide rod 5, and it is guide groove 4 that right-hand member connects, and guide rod 5 and guide groove 4 be fit mutually, and guide rod 5 in the present embodiment and guide groove 4 cross sections are rectangle, and both are the gap fit.Hatband 3 is Y-shaped, and two ends branch is hinged with the posterior segment of guide rod 5, guide groove 4 respectively up, and hatband 3 down placed in the middle is provided with and opposite side hatband 3 buckle structure mutually.Under the normal condition, hat lining 2 in the safety cap is open-shaped, strain hatband 3 when wearing downwards, by hatband 3 up two ends branch tractive be located at about hat lining 2 bases the guide rod 5 and the guide groove 4 of end phase fit, at the effect lower guide rod 5 of horizontal force and guide groove 4 to intrinsic displacement, until hat lining 2 during with wearer's head circumference goodness of fit with hatband 3 two ends hasp mutually.The utility model is simple in structure, regulates degree of having, and during prestowage hatband 3 is fastened hat lining 2 adjustings that link and put in place, otherwise then safety cap floats over wearers head.Application of the present utility model can avoid not being hatband 3 phenomenons, effectively improves the use value of safety cap, reduces the possibility of head injuries.
The guide rod 5 in the utility model and the cross section of guide groove 4 are made semicircle or circle all has identical effect.
