The first draw-in groove 6 and the second draw-in groove 7 on the lower limb of slip lid 4, the raised side for being located at light-emitting window, sets near light-emitting window
Put, the slip lid 4 block completely described go out optical channel when the corresponding raised position at form the first draw-in groove 6, the cunning
Lid 4 fully open described go out optical channel when the corresponding raised position at form the second draw-in groove 7 so that slip lid 4 is complete
When closing out optical channel, projection is coordinated with the first draw-in groove 6, is closed with locking slip lid 4, is being fully opened out optical channel
When projection coordinate with the second draw-in groove 7, to lock slip lid 4 in open mode, the setting of position limiting structure causes slip lid 4 with slide rail knot
Being slidably matched for structure 3 is more solid and reliable, it is ensured that during laser lamp is moved and in emergency circumstances promote rapidly slip lid 4
When slip lid 4 do not fall off.
Yet further, the projection is activity raised 5, forms and set perpendicular to lower horizontal slide rail on rectangular mounting plate 1
The chute that puts, the opening of chute are concordant with the lower surface of lower horizontal slide rail, and the activity raised 5 is slidably disposed in the cunning
In groove, and at the opening of chute, it is provided with the spacing rib for preventing the activity raised 5 from deviating from from the chute, activity
It is provided with inside the chute at raised 5 back sides for supporting movable raised 5 compression elastic piece, the compression elastic piece is elasticity pressure
Spring, settings of activity raised 5 not only increase the smooth degree of the slip of slip lid 4, and behaviour when enhancing user's promotion slip lid 4
Make feel.
It should be noted that in other embodiments, the projection can also be take shape in elastic convex on rail structure 3
Rise, the raised elastic card with draw-in groove is completed by the elastic deformation of improved plastics structural shape and matched somebody with somebody.
Embodiment two
A kind of laser lamp of the present embodiment, including housing and the laser instrument located at the enclosure interior, delicolor controller and
Scanning system, and the light-emitting window protection device described in embodiment one, the light source of the corresponding laser instrument of the housing
Place offers light-emitting window, and the light-emitting window protection device is closed on the outside of the light-emitting window, closes on the outside of the light-emitting window of laser lamp
There is the light-emitting window protection device, be conducive to the normal use of laser lamp internal component, and can be in case of emergency rapid
Block laser, it is to avoid the situation of personal injury occur, convenient and swift.
Obviously, above-described embodiment is only intended to clearly illustrate example, and the not restriction to embodiment.Right
For those of ordinary skill in the art, can also make on the basis of the above description other multi-forms change or
Change.There is no need to be exhaustive to all of embodiment.And thus extended obvious change or
