Description
One, technical field
The utility model relates to the syndeton of a kind of syndeton of physical protection articles for use, particularly a kind of helmet glasses lens.
Two, background technology
Existing helmet glasses lens be generally being connected of helmet body fixedly, complex structure, mounting or dismounting palpus specific purpose tool are wasted time and energy, and be very inconvenient.Once the someone passed through mounting or dismounting switch and spring are installed, and had realized the effect of convenience mounting or dismounting, but still existed the defective of operation effort.
Three, summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and the eyeglass syndeton of a kind of mounting or dismounting simple in structure, convenient, rapid operation is provided.
Task of the present utility model is finished like this: the helmet glasses lens syndeton is made up of eyeglass (1) and connector (2), be provided with on the eyeglass and plug (11) be installed and adjusted tooth bar (12), on this installation plug and the adjustment tooth bar spacing block set (111) and (121) are arranged respectively; Have respectively on the connector with the installation plug (11) and the adjustment tooth bar (12) of eyeglass and mate corresponding connector mounting receptacle (21) and adjust double wedge (22), the other correspondence of mounting receptacle (21) and adjustment double wedge (22) is provided with limited impression (211) and reaches (221); Side at connector is provided with mounting or dismounting switch (23), and it is connected with connector by fulcrum (26).The mounting or dismounting switch is to be divided into withstanding part (231) and handle portion (232) with the fulcrum, and spring (24) one ends are fixed on the spring base (25), and the other end is fixed on the below of mounting or dismounting switch withstanding parts (231).
The utility model is simple in structure, and installing/dismounting need not specific purpose tool, and is convenient and swift, and rapid operation is applicable to that the eyeglass of the helmet and similar products connects.

Five, the specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The helmet glasses lens syndeton is made up of eyeglass (1) and connector (2), is provided with on the eyeglass plug (11) to be installed and to be adjusted tooth bar (12), on this installation plug and the adjustment tooth bar spacing block set (111) and (121) is arranged respectively; Have respectively on the connector with the installation plug (11) and the adjustment tooth bar (12) of eyeglass and mate corresponding connector mounting receptacle (21) and adjust double wedge (22), the other correspondence of mounting receptacle (21) and adjustment double wedge (22) is provided with limited impression (211) and reaches (221); Side at connector is provided with mounting or dismounting switch (23), and it is connected with connector by fulcrum (26).
The mounting or dismounting switch is to be divided into withstanding part (231) and handle portion (232) with the fulcrum, forms lever, reaches the labor-saving effect.Spring (24) one ends are fixed on the spring base (25), and the other end is fixed on the below of mounting or dismounting switch withstanding parts (231).Utilize the elastic reaction of spring that the mounting or dismounting switch is resetted.
With the plug spacing block set (111) of eyeglass, socket limited impression (211), the double wedge limited impression (221) that tooth bar spacing block set (121) is inserted in connector respectively, thereby eyeglass and connector are linked together, and, adjustment tooth bar (12) on the eyeglass just in time with connector on the adjustment double wedge coincide, with mounting receptacle (21) is that eyeglass is rotated in the center of circle, can make different teeth do corresponding interlock, thereby realize changing the also purpose of fixing len angle.
When the mobile connector one side mounting or dismounting of the tooth bar spacing block set (121) of eyeglass switch (23) notch position, stir mounting or dismounting switch knob portion (232), tooth bar spacing block set (121) can formed indentation, there break away from double wedge limited impression (221) after the displacement of mounting or dismounting switch withstanding part (231), thereby make eyeglass (1) break away from connector (2), realize the dismounting purpose.
Step is opposite during installation, promptly earlier plug spacing block set (111) is inserted in the socket limited impression (211) of connector, stir again and install and remove switch knob portion (232) then, formed indentation, there enters double wedge limited impression (221) after making tooth bar spacing block set (121) by the displacement of mounting or dismounting switch withstanding part (231), unclamp mounting or dismounting switch knob portion (232) then, it is automatically reset under the effect of spring (24) close breach, and sealing double wedge limited impression (211), thereby eyeglass (1) and connector (2) are fused.
Consider that for laborsaving and handled easily the angle between handle portion (232) and the withstanding part (231) is an acute angle.Like this, the elastic force action direction of power thrusts and spring is different, more convenient operation.The setting of handle portion increases the finger and the contact area of mounting or dismounting switch, and operation more feels light, comfortable.
Certainly, the angle between handle portion (232) and the withstanding part (231) also can be the obtuse angle; Angle between handle portion (232) and the withstanding part (231) also can equal 180 ° or greater than 180 °.
