Abstract
The utility model relates to an improved structure of an internal lens of a bi-lenses helmet. The structure includes a helmet body and an internal lens, and is characterized in that a slide strip is arranged at the top of the helmet body, slide rails are arranged on inner walls on two sides of the helmet body, the middle part on the upper edge of the internal lens is connected with the slide strip, and two sides of the slide strip are correspondingly embedded in slide rails on inner walls on two sides of the helmet body to enable the internal lens to have a tri-point slide structure. Therefore, through the tri-point slide structure including one middle point which slides by pushing and two sides which slide without fixation point for positioning, the internal lens is mounted on the helmet body, the internal lens in the moving process can slide along the rails by adopting the central part of the helmet as the central axis, no phenomena of left and right swinging, wobbling or dripping off can appear. The structure is characterized by scientific structural design, high reliability, good firmness, good durability and long service life.
Description
Technical field
The utility model relates to a kind of two lens helmet.
Background technology
China Patent No. is that ZL200820200476.X, name are called the patent documentation of " a kind of two lens helmet ", and the patent documentation that number of patent application is 200610004286.6, name is called " guard apparatus that is used for the helmet " discloses the helmet technical scheme that has two lens respectively.These two parts of helmet technical scheme something in commons are: the interior eyeglass and the outer lens of the helmet is the rotatable fixing mode of two sidespins of coaxial or shared fixed endpoint and installs.And the interior eyeglass that this class mode is installed, its fastness and reliability are all very poor.In daily use, interior eyeglass is easy to occur rolling, swinging, even the phenomenon that comes off, and makes the very poor durability of the helmet, and service life is very short.
The utility model content
The purpose of this utility model is to address the above problem, and provides that a kind of scientific structure design, reliability height, fastness are good, the interior eyeglass structure-improved of long service life, the simple load and unload two lens helmet.
The technical solution of the utility model is achieved in that
A kind of interior eyeglass structure-improved of the two lens helmet, comprise helmet body and interior eyeglass, its characteristics are that the top of described helmet body is provided with slider bar, on two side inwalls of helmet body, be provided with slide rail, the top middle part of eyeglass is connected with slider bar in described, and its dual side-edge is flush-mounted in accordingly respectively on the slide rail of helmet body two side inwalls and makes interior eyeglass be the bikini slide construction on helmet body.
For making slider bar have easy to assembly, simple in structure, the characteristics smoothly of sliding, the top of above-mentioned helmet body offers hole slot, above-mentioned slider bar is placed through on this hole slot, and also be respectively equipped with supporting plate spare and cover piece on the inner top surface of the helmet body that is positioned at this hole slot place and outer end face, this slider bar clamps spacing being slidably mounted on the helmet body by this supporting plate spare and cover piece upper and lower.
For the assembling that the makes slider bar reasonability that more becomes, the rearward end of above-mentioned slider bar is provided with limited block again, and this limited block is set and slided on the chute that offers accordingly on the cover piece.
Technical characterstic of the present utility model:
Adopt bikini slide construction that an intermediate point sliding, two sides form with the slip location of no fixing point that interior eyeglass is installed on structure on the helmet body, eyeglass is in motion process in making, be with the motion that to be the axis slide along track of helmet central part, can not go out left and right swing, rock, the phenomenon that perhaps comes off has scientific structure design, reliability height, fastness is good, durability is good, the characteristics of long service life; And solved effectively the existing two lens helmet because of adopt the rotatable fixing mode of two sidespins install in the fastness that exists of eyeglass and poor reliability, very poor durability, service life very short problem.And because the installation of eyeglass all adopts the mode of no screw to fix in whole, it is very convenient, simple to make interior eyeglass dismounting get up, and efficiency of assembling is very high.
Below in conjunction with accompanying drawing the utility model is further described:
