Description

The helmet glasses lens articulating device

Technical field

The application relates to a kind of helmet glasses lens articulating device.

Background technology

Rider personnel for electric motor car, motorcycle; the helmet is essential; its effect is that the rider personnel are played a protective role; the place ahead at the helmet is provided with eyeglass; be provided with after the eyeglass; can play the effect of keeping out wind and rain to the rider personnel, can not cause again to stop that a transition jockey must be arranged between the eyeglass and the helmet the visual field of riding personnel.

For traditional helmet, the syndeton of eyeglass and headpiece case is: eyeglass a fixedly ear lid each side arranged, headpiece case a firm banking each side arranged, firm banking is connected with base by screw; This structure is tradition relatively, and has following defective:

Waste time and energy when 1, eyeglass being installed, also inconvenient during dismounting, the personnel that particularly ride need eyeglass is taken off once in a while, clean, wiping, replacing, and are all inconvenient, are necessary to improve;

2, for the not hard people of some nail, this structure is easier to cause jackknifing of operator's nail or damage, if use hard device, is easy to because cause damaged products because of carelessness in the operating process;

3, traditional structural design is easy to cause the connector fracture owing to exist fault of construction.

Summary of the invention

The application's purpose is to provide a kind of helmet glasses lens articulating device, and is behind employing the utility model, more convenient when the user dismantles or installs eyeglass.

Its technical scheme is as follows:

A kind of helmet glasses lens articulating device, headpiece case a base each side arranged, eyeglass a fixedly ear lid each side arranged; On each base, be provided with arc guide barrel, the end of arc guide barrel is provided with bayonet socket, the width of bayonet socket is greater than the width of arc guide barrel, cover at fixing ear and to be provided with the guide card that adapts with arc guide barrel, the end of guide card is provided with grab, and grab inserts arc guide barrel from bayonet socket, is provided with the elasticity block piece at the bayonet socket place, the control end button of elasticity block piece exposes, the axis coinciding of left side arc guide barrel, right side arc guide barrel.

Intention of the present utility model is, control end button by the operating flexibility block piece can make the elasticity block piece block bayonet socket or bayonet socket is exposed, so that grab snaps in bayonet socket or breaks away from bayonet socket, when grab snaps in bayonet socket, eyeglass can be loaded on the headpiece case, when grab breaks away from bayonet socket, eyeglass can be pulled down from headpiece case, the installation and removal of eyeglass are very convenient; After eyeglass was installed on headpiece case, guide card can move in arc guide barrel, blocked or collapse state thereby eyeglass is with respect to described headpiece case.

Further improvement of the utility model is:

Described arc guide barrel on described each base is two sections, and these two sections arc guide barrels are relative; Corresponding, the described guide card that each described fixedly ear covers also is two, and the grab on two guide cards is towards same direction.Fixedly be connected the location by two guide cards between ear lid and the base, its connection is more reliable, and two sections arc guide barrels can be avoided guide card generation beat.

Described elasticity block piece comprises catch and is located at the spring of catch below.

Center at described fixedly ear lid is provided with circular hole, and the middle part of described catch is corresponding with the circular hole position at fixing ear lid center, is described control end button in the middle part of the catch; During installation or removal, finger sees through circular hole the control end button is operated.

Be provided with corresponding positioning tooth between described fixedly ear lid and base, positioning tooth when eyeglass rotates with respect to helmet block, moves softer, stable fixedly playing damping action between ear lid and the base.

Described base and described headpiece case are separate, and described base fixes by connector and described headpiece case, and base is relatively independent, can process separately, are connected with headpiece case after machining again, and be easy to process.

When described guide card slided in described arc guide barrel, described eyeglass can be with respect to described headpiece case and blocks or collapse state; When described guide card was relative with described bayonet socket, described eyeglass can be collapse state with respect to described headpiece case; That is to say to have only when eyeglass is in collapse state with respect to headpiece case, guide card just can be relative with bayonet socket, and could take off eyeglass this moment.

Only need adjust the length of arc guide barrel a little, just can satisfy the eyeglass folding angle requirement of various criterion.

The specific embodiment

As shown in Figure 1 to Figure 3, a kind of helmet glasses lens articulating device, headpiece case 1 a base 4 each side arranged, eyeglass 2 a fixedly ear lid 3 each side arranged; On each base 4, be provided with arc guide barrel 5, the end of arc guide barrel 5 is provided with bayonet socket 6, the width of bayonet socket 6 is greater than the width of arc guide barrel 5, fixedly be provided with the guide card 7 that adapts with arc guide barrel 5 on the ear lid 3, the end of guide card 7 is provided with grab 8, and grab 8 inserts arc guide barrel 5 from bayonet socket 6, and 6 places are provided with the elasticity block piece at bayonet socket, the control end button 10 of elasticity block piece exposes, the axis coinciding of left side arc guide barrel 5, right side arc guide barrel 5.

Wherein, base 4 is separate with headpiece case 1, and the installing hole 15 that connector (being screw 13) passes on the base 4 is fixing with headpiece case 1 with base 4; Described elasticity block piece comprises catch 9 and is located at the spring 16 of catch 9 belows, and the arc guide barrel 5 on each base 4 is two sections, and these two sections arc guide barrels 5 are relative; Corresponding, each fixedly the guide card 7 on the ear lid 3 also be two, the grab 8 on two guide cards 7 is towards same direction; Center at fixing ear lid 3 is provided with circular hole 11, and the middle part of catch 9 is corresponding with circular hole 11 positions that fixing ear covers 3 centers, and catch 9 middle parts are control end button 10; When guide card 7 slided in arc guide barrel 5, eyeglass 2 can be with respect to headpiece case 1 and blocks or collapse state; When guide card 7 and bayonet socket 6 were relative, eyeglass 2 can be collapse state with respect to headpiece case 1; Fixedly be provided with corresponding positioning tooth 12 between ear lid 3 and the base 4, fixedly also be provided with case ring 14 on the ear lid 3.

In the present embodiment, if eyeglass 2 will be pulled down from headpiece case 1, press the control end button 10 that is positioned at circular hole 11 centers, control end button 10 overcomes the elastic force of spring and moves down, catch 9 moves down simultaneously and bayonet socket 6 is exposed, grab 8 on the eyeglass 2 breaks away from from bayonet socket 6, can easily eyeglass 2 be pulled down from headpiece case 1; If want eyeglass 2 is loaded on the headpiece case 1, press control end button 10 again, catch 9 moves down and bayonet socket 6 is exposed, grab 8 on the eyeglass 2 snaps in from bayonet socket 6, guide card 7 is positioned at arc guide barrel 5, and can slide in arc guide barrel 5, thereby realizes the rotation of eyeglass 2 with respect to headpiece case 1; Bayonet socket 6 is arranged at correct position, when eyeglass 2 is collapse state with respect to headpiece case 1, could carries out dismounting to eyeglass 2, security is higher.

Below only be the application's preferred embodiment, do not limit the application's protection domain with this; Do not violate any replacement and the improvement of being done on the basis of the application design, all belonging to the application's protection domain.
