Preferably: described movable part is double-layered cylinder structure, including inner core and urceolus, wherein inner core is enclosed construction away from the end of shell, described urceolus and inner core all can rotate around respective axis, the barrel of urceolus is provided with some first openings, the barrel of inner core is provided with some second openings, when described first opening and the second register, forms described through hole.
By such scheme, rotate urceolus or inner core make both relatively rotate just to change the aperture of through hole, and energy can the gross area of fine adjustment louvre, enable shell to better adapt to different use environment.
Preferably: described urceolus is provided with baffle ring away from one end of enclosure, described spring is sheathed contacts with shell and baffle ring respectively with on urceolus and the two ends of spring.
Preferably: described locking mechanism includes fixture block and snap ring, described fixture block is located at the periphery of baffle ring, described snap ring is fixed with shell and coaxial with urceolus, described snap ring is provided with the inwall of notch and the snap ring passed through for fixture block and is provided with the annular indentation rotated with urceolus for fixture block, and described notch communicates with indentation.
Preferably: described inner core is provided with knob away from one end of shell.
By such scheme, can be so that rotating inner core.
Compared with prior art, the utility model has the advantage of: when the power of vehicle power amplifier is higher or ambient temperature is higher, movable part can be stretched out, to increase total area of dissipation of the louvre of housing, be beneficial to heat radiation；And when the power of vehicle power amplifier is relatively low or ambient temperature is relatively low, can prevent dust from entering enclosure interior movable part retraction enclosure interior.This shell can preferably meet the dust-proof and demand of heat radiation.

Detailed description of the invention
Such as Fig. 1, a kind of vehicle power amplifier housing 1, including housing, housing slidably connects a movable part 2.Comparison Fig. 1 and Fig. 2, movable part 2 retraction housing 1 is internal and can stretch out housing 1 outside, is provided with the cavity that communicate internal with housing 1 in movable part 2, and the sidewall of movable part 2 is provided with the through hole communicated with cavity.When movable part 2 stretches out housing 1 outside, its through hole and cavity connect internal for housing 1 with outside air, make the gross area of the louvre of housing 1 increase, and the partial heat within housing 1 is distributed by movable part 2, is beneficial to dispel the heat；When after the power reduction or ambient temperature reduction of vehicle power amplifier, on vehicle power amplifier housing 1, original louvre be enough to distribute the heat within housing 1, now, there is no need to make movable part 2 be maintained at the state of stretching out, if that movable part 2 retraction housing 1 is the most internal, dust only can be made to pass through through hole and to enter housing 1 inside.Movable part 2 housing 1 of retracting can be made internal by pressing.
Such as Fig. 6, movable part 2 is double-layered cylinder structure, including inner core 4 and urceolus 3, inner core 4 is provided with end cap 6 away from the end of housing 1 makes this end for sealing structure, the edge of the end cap 6 of inner core 4 stretches out outside cylinder, urceolus 3 is provided with baffle ring 9 away from the end of housing 1 and is fixed with the second snap ring 5 on baffle ring 9, coaxial with inner core 4 and the second snap ring 5 the cross sectional shape of second snap ring 5 is inverted L-shaped, the edge of the end cap 6 of inner core 4 is positioned at the indentation of the second snap ring 5, such urceolus 3 just can relatively rotate with inner core 4 and both without departing from.It addition, be positioned at the end of housing 1 at urceolus 3 also to be provided with baffle ring 9, consequently, it is possible to movable part 2 would not separate with housing 1 during sliding.The barrel of inner core 4 is provided with some second openings 7, the barrel of urceolus 3 is provided with some first openings 8, form aforementioned through-hole when the first opening 8 aligns with the second opening 7.Rotate urceolus 3 or inner core 4 to make both relatively rotate just to change the aperture of through hole, and energy can the gross area of fine adjustment louvre, make housing 1 can better adapt to different use environment.
As improvement, being arranged with spring 10 in urceolus 3 periphery, such as Fig. 6, the two ends of spring 10 contact with baffle plate with outside housing 1 respectively, spring 10 is in compressive state all the time, and spring 10 is used for promoting movable part 2 stretch out housing 1 outside and activity be will remain under the state of stretching out.
It addition, be additionally provided with locking knot mechanism on housing 1.Comparison Fig. 3 and Fig. 6, locking mechanism includes fixture block 12 and the first snap ring 11, fixture block 12 is located at the periphery of baffle ring 9, and the first snap ring 11 is fixing and coaxial with urceolus 3 with housing 1, and the first snap ring 11 is provided with the notch 13 passed through for fixture block 12 and notch 13 communicates with the indentation of the first snap ring 11.After movable part 2 is pushed back housing 1 inside, fixture block 12 enters in the indentation of the first snap ring 11 also by notch 13, after fixture block 12 enters the indentation of the first snap ring 11, rotates urceolus 3 and makes fixture block 12 be locked by the first snap ring 11, just movable part 2 can be locked, prevent it to be automatically popped up.
Such as Fig. 2, for ease of rotating inner core 4, inner core 4 is provided with knob 14 away from one end of housing 1.
By such scheme, can be so that rotating inner core.
Below being only preferred implementation of the present utility model, protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
