Embodiment

Referring to Fig.1, a kind of anti-aging chamber, including including cabinet 2, bottom plate 3 and ultraviolet lamp 4.Bottom plate 3 is placed on cabinet 2 bottom, ultraviolet lamp 4 are mounted on the side wall of cabinet 2.When test, safety cap 1 is placed on bottom plate 3, it is right to open ultraviolet lamp 4 Safety cap 1 is irradiated.

Because the cap of safety cap 1 cannot be stablized and be placed on bottom plate 3 along not being the smooth setting of rule.If The position of safety cap 1 changes in test process, can seriously affect test result.

As shown in Figure 1 and Figure 2, fixed device 5 includes sleeve 51, column 52, jackscrew 53, reed 54 and bolt 55.

The nozzle of sleeve 51 is fixedly mounted on straight up on bottom plate 3, and column 52 is socketed in 51 the inside of sleeve vertically, is being covered Threaded hole is provided on cylinder 51, jackscrew 53 and threaded hole cooperate, column 52 held out against." U "-shaped reed 54 passes through bolt 55 Mating reaction with threaded hole is fixedly mounted on column 52.

Safety cap 1 is placed on 52 top of column, and the hatband of safety cap 1 covers on reed 54, and the width of reed 54 is greater than hatband, Hatband can cover completely on it, because the reed 54 of " u "-shaped gives an elastic force on the outside of hatband, under the action of elastic force, Hatband struts completely, and safety cap 1 is fixed on column 52, and the offset of position will not occur.

In actual use, the light scattering of ultraviolet lamp 4 on safety cap 1, and because 1 cap shell of safety cap similar to spherical shape, So ultraviolet lamp 4 is radiated at, the distance in cap shell is not identical, and the data measured are not accurate.In order to measure more accurate number According to the angle of safety cap 1 is adjusted.

Specifically, unscrewing jackscrew 53 when the angle of safety cap 1 is adjusted, column 52 is rotated, safety cap 1 is rotated, Then jackscrew 53 is tightened again, column 52 is fixed, it can satisfy the demand to each position test of safety cap 1.

When picking and placing bottom plate 3, operator's direct contact base plate 3 of hand, the shake of hand may make safety cap 1 tested Positional shift, cause test result impacted.In order to solve the problems, such as preferably to pick and place bottom plate 3, sliding rail 6 is installed and is determined Position part 7.

As shown in Figure 1, being provided with a groove from inside to outside in the bottom of cabinet 2, two are horizontally installed in bottom portion of groove The "T"-shaped sliding rail 6 of item, bottom plate 3 are mounted on sliding rail 6, and 3 lower part of bottom plate is provided with "T"-shaped slot, and "T"-shaped slot and sliding rail 6 are completely suitable Match, bottom plate 3 can be placed on groove, and the upper edge of bottom plate 3 is higher by the bottom of cabinet 2.It is fixedly mounted in the upper edge of bottom plate 3 One locating piece 7 is provided with socket in 2 bottom of cabinet of groove two sides, and the output end of locating piece 7 and the position of socket are corresponding, And socket can be injected and cooperated.

After test, safety cap 1 shakes during removing cabinet 2, unknown to the part label of test Really, safety cap 1 is taken out for convenience, and is not had an impact to its part of detecting, is drawn a point at the center of test zone with pen, is taken out Bottom plate 3 out are taken out safety cap 1 by fixed position.

As shown in figure 3, locating piece 7 includes box body 71, baffle 72, spring 73, slide bar 74 and handle 75.

Box body 71 is vertically installed on bottom plate 3, and baffle 72 is placed on inside box body 71, and spring 73 is in extended state and installation In box body 71, spring 73 pushes down on baffle 72, and slide bar 74, which penetrates box body 71 and baffle 72 vertically and fixes with baffle 72, to be connected It connects, handle 75 is mounted on 74 upper end of slide bar.

The "T"-shaped and sliding rail 4 of bottom plate 21 is corresponding to be placed, and bottom plate 21 is promoted in cabinet 2, when 54 He of slide bar of locating piece 55 The socket of 2 bottom of cabinet injects in socket slide bar 54 when corresponding to, and bottom plate 3 is fixed, avoids during the test, bottom plate 3 is in cunning It is moved on rail 4, deviation is generated to test result.

Because the light of ultraviolet lamp 4 is scattered on safety cap 1, the irradiation situation on safety cap 1 cannot be guaranteed unanimously, The accuracy of test result is influenced, for a specific region by light-illuminating on safety cap 1, shading is installed Component 8.

As shown in Figure 1, being fixedly installed with light shield device 8 close to the position of ultraviolet lamp 4 in 2 inner top of cabinet.

As shown in figure 4, light shield device 8 includes fixed link 81, ball-joint structure 82 and barn door 63.

Fixed link 81 is fixed on the top of cabinet 2 straight down, and ball-joint structure 82 is fixedly mounted on the another of fixed link 82 One end, ball-joint structure 82 can rotate certain angle according to actual needs.Barn door 83 is fixed in ball-joint structure 82, It is provided with loophole among the plate face of barn door 83, ultraviolet light is passed through the aperture of barn door 83, reaches to concentrate light and shine Penetrate the purpose on safety cap 1.

When doing anti-aging test, safety cap 1 is placed on 52 top of column, moves it not.Hatband is covered in reed On 54, safety cap 1 is made not rotate on column 52.Bottom plate 3 and the cooperation of sliding rail 6 are placed, and bottom plate 3 is promoted into cabinet In 2, the slide bar 54 of locating piece 7 is inserted into the socket of 2 bottom of cabinet, and the position of bottom plate 3 is fixed.Ultraviolet lamp 4 is opened, shading is adjusted The angle of plate 83 makes 4 light of ultraviolet lamp be radiated at the region for wanting test on safety cap 1 by loophole.When needs are to safety When 1 different zones of cap are tested, jackscrew 53 can be unscrewed, rotate column 52, adjust the direction of safety cap 1 and then it is carried out Ageing resistance can be carried out test.After the test, it pulls handle 55 that slide bar 54 is made to be detached from opening, bottom plate 3 is pulled to outside cabinet 2, The taking-up for completing safety cap 1, finally analyzes test result.

The embodiment of present embodiment is the utility model preferred embodiment, not limits the utility model according to this Protection scope, therefore: it is practical new should all to be covered by this for the equivalence changes that all structures, shape, principle according to the utility model are done Within the protection scope of type.
