Detailed description of the invention
As shown in Figure 1 to 4, one wears the adjustable earmuff of dual-purpose type after wearing, including U-bracket 10, left earmuff 20 and the right side
Earmuff 30;Described U-bracket 10 is internal offers U-shaped guide groove 11;U-bracket about 10 both ends horizontal direction is respectively fixed with
One bulb plunger 12 and the second bulb plunger 13;The structure of left earmuff 20 and right earcup 30 is symmetrical;Left earmuff 20 includes adjusting
Joint connecting rod 21, support seat 22 and earmuff body 23;Support seat 22 inside and offer two regulating tanks 220;Two regulating tanks 220
Including center circular groove, fan-shaped annular groove, head position rectangular channel 2201 straight down and horizontal forward rear position rectangular channel 2203;In
Heart circular groove is connected with fan-shaped annular groove, head position rectangular channel 2201, rear position rectangular channel 2203 respectively;In two regulating tanks 220
The center of heart circular groove is fixed with central shaft 221;Offer respectively on the sidewall of head position rectangular channel 2201 and rear position rectangular channel 2203
There are head position spacing hole 2202 and rear position spacing hole 2204;Uniformly offer some spacing on the upper left end face of regulation connecting rod 21
Groove 211;The bottom of regulation connecting rod 21 offers slide slot 210 and the spacing hole 2101 that left and right is run through the most successively;Adjust
Joint connecting rod 21 is set on central shaft 221 by slide slot 210;Support and offer hole, head position and rear position on the left side of seat 22
Hole;Head hole, position and hole, rear position are corresponding with head position spacing hole 2202 and rear position spacing hole 2204 respectively;Head hole, position and rear position hole
Annular spacing groove is offered on sidewall;It is respectively fixed with head position on the external cylindrical surface of head position limited post 222 and rear position limited post 224
Annular stop block and rear position annular stop block;Head position limited post 222 and rear position limited post 224 are respectively by head position annular stop block
It is plugged in the annular spacing groove in hole, head position and hole, rear position with rear position annular stop block;Head position annular stop block and rear position annular limit
Position block left side respectively and hole, head position and hole, rear position annular spacing groove end face between be provided with head position stage clip 223 and rear position
Stage clip;The top of the regulation connecting rod 21 of left earmuff 20 and right earcup 30 is inserted in U-shaped guide groove 11 from U-shaped guide groove 11 both sides;
The bulb of the first bulb plunger 12 and the second bulb plunger 13 is plugged in the regulation connecting rod 21 of left earmuff 20 and right earcup 30
In stopper slot 211.
As shown in Figure 1 to 4, spacing hole 2101 and head position limited post 222 and the rear position limited post 224 of connecting rod 21 are regulated
Size corresponding.
U-bracket 10 is the soft bar of silica gel, and regulation connecting rod 21 is metal tie rods.
Screwed hole is offered on the right side of seat 22 as it is shown in figure 1, support;Earmuff body 23 includes screw rod connecting portion 232
Warming with sponge piece 231;Sponge is fixed on for warming piece 231 on the right side of screw rod connecting portion 232;Warming piece of 231 right-hand members of sponge
The ear's protector that can place ear is formed on face;Earmuff body 23 is screwed onto on support seat 22;The protector side of having of ear
Tropism, main protection part is positioned at the rear portion of ear's protector.
As shown in Figure 1 to 4, width and head position rectangular channel 2201 and the width of rear position rectangular channel 2203 of connecting rod 21 are regulated
Spend identical;Slide slot 210 is elongated hole;The diameter of center circular groove is more than the center of circle, bottom and the regulation connecting rod 21 of slide slot 210
Distance between sideline, bottom.
Earmuff wear or after wear control method:
If needing to wear, regulation connecting rod 21 is made to insert in head position rectangular channel 2201, then outside plug position limited post
222, then regulation connecting rod 21 inwardly plugs on earth, decontrols head position limited post 222, and head position limited post 222 is at head position stage clip 223
Effect under, the end of head position limited post 222 through regulation connecting rod 21 spacing hole 2101 insert in head position spacing hole 2202,
Then regulation U-bracket and left earmuff and the relative distance of right earcup;
If worn after Xu Yaoing, making regulation connecting rod 21 depart from head position limited post 222, then sliding tray 210 is around central shaft 221
Rotate, after making regulation connecting rod 21 insert in position rectangular channel 2203, the most outwards pull out rear position limited post 224, then regulate connection
Bar 21 inwardly plugs on earth, position limited post 224 after relieving, rear position limited post 224 under the effect of rear position stage clip (not shown), after
The end of position limited post 224 insert through the spacing hole 2101 of regulation connecting rod 21 after in position spacing hole 2204, then regulate U-shaped
Support and left earmuff and the relative distance of right earcup.
Left earmuff 20 and right earcup 30 can pull out from U-bracket 10.
