Abstract
The utility model relates to a probe shutter protective device of a shimmer analyzer. The structure of the probe shutter protective device comprises a shutter piece, a shutter plate, a top rod, a shutter rod and an elastic element positioned between the shutter plate and the shutter rod, wherein the shutter plate is provided with a guide hole, and the shutter rod is of a folding rod structure; and the tail end of the shutter rod is fixed with the shutter piece and provided with the guide hole used for containing the shutter plate, and the front end face of the shutter rod is contacted with the top rod. The shutter protective device provided by the utility model can effectively protect a probe from the interference of the outside natural light, so that the measuring result can not be influenced, the device is simple in structure, is convenient in use, and has lower cost.
Description
Technical field
The utility model relates to a kind of probe shutter protective device of faint light analyser, belongs to the faint light detection field.
Background technology
The faint light analyser adopts advanced photon counting detection technique, can realize the detection to atomic low light level signal, so the lucifuge of instrument is treated as emphasis of design.In the time of particularly in the sample test dish is packed instrument into, how to protect probe not disturbed by the extraneous natural light of instrument and influence measurement result, become the most important thing of instruments design.
For addressing this problem, the modes of cutting off the WV of probe when opening instrument and renovating automatically that adopt are seen light to guarantee that probe is not charged more in the prior art.But actual conditions are, even probe long-time induction natural light under powering-off state also as easy as rolling off a logly causes the rising of probe background values and causes that the instrument test result's is inaccurate.
In addition, also there is the drawer-type structure of employing to pull out test pallet, again the sample test dish put into pallet and push the instrument build-in test with the money instrument.The advantage of this structure is, when drawer tray was pulled out, the drawer afterbody instrument connection of will popping one's head in blocked, thereby has protected probe not disturbed by extraneous natural light.But its shortcoming is, after drawer is pulled out, puts into the sample test dish, when pushing instrument, sample test dish upper surface easily and the upper cover plate of instrument camera bellows scratch, push-plate puts in storage smoothly.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of probe shutter protective device of faint light analyser is provided, and through linkage assembly, realizes the interlock of shutter, and the protection probe does not receive the interference of extraneous natural light.
The purpose of the utility model realizes in the following manner: a kind of probe shutter protective device of faint light analyser; Comprise shutter disk 11, shutter plate 12, push rod 15, release lever 16 and the flexible member 14 between shutter plate 12 and release lever 16; Shutter plate 12 is provided with pilot hole; Release lever 16 is the pole structure, and the end of release lever 16 is fixed with shutter disk 11 and the pilot hole of the shutter plate 12 of packing into, and the front end face of release lever 16 contacts with push rod 15;
Wherein, push rod 15 scribbles lubricant with the position that release lever 16 contacts; Push rod 15 is fixed in to be renovated on 13, opens when axially going up rotation when renovating 13, and push rod 15 is correspondingly around axially rotation down;
Said flexible member 14 can be fixed on release lever 16 or the shutter plate 12 by an end, also can be separately fixed on release lever 16 and the shutter plate 12 at two ends, if adopt spring as flexible member, can also spring housing be contained on the release lever 16.
Compared with prior art, the probe shutter protective device of the utility model has been avoided after the probe outage still sensitization and the troublesome shortcoming of drawer-type structure, has protected the interference of popping one's head in because of extraneous natural light not influence measurement result effectively.In addition, this structural design is simple, has reduced the difficulty of machining, thereby has reduced instrument cost.

Embodiment
Specify the embodiment of the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the probe shutter protective device of the utility model comprises shutter disk 11, shutter plate 12, spring 14, push rod 15 and release lever 16; Wherein, Shutter plate 12 is provided with pilot hole, and release lever 16 is the pole structure, earlier release lever 16 is inserted in the pilot hole of the shutter plate 12 of packing into behind the spring 14; Then shutter disk 11 is fixed on the end of release lever 16, and the front end face of release lever 16 is contacted with push rod 15.Among Fig. 2, push rod 15 is fixed on renovating on 13 of faint light analyser through being threaded into formula, renovates 13 and is closure state; Push rod 15 levels contact this moment release lever 16; Spring is compressed, and shutter disk 11 exposes the exploration hole of probe 10 just, sees schematic top plan view among Fig. 3 for details.As shown in Figure 4; When renovating 13 when upwards opening; Correspondingly around axially rotation down, the release lever 16 of contact moves to the direction away from shutter plate 12 under the elastic force effect of spring 14 push rod 15 with it, moves in the same way thereby drive shutter disk 11; And then shelter from probe 10 exploration hole, shown in the vertical view of Fig. 5.In like manner, when renovating 13 when closed, will pop one's head in 10 exploration hole of shutter disk 11 is opened, shown in the vertical view of Fig. 6.
Can also adopt other flexible members between shutter plate 12 and the release lever 16,, sheltered from by shutter disk 11 fully, and renovate 13 exploration holes when opening and open fully and get final product as long as guarantee to renovate the exploration hole of 13 probes 10 when closed such as rubber band; In addition, can an end of flexible member be fixed on the shutter plate 12, the other end is fixed on the release lever 16, also can be fixed on shutter plate 12 or the release lever 16 by an end with flexible member.Smooth and easy, stable for guaranteeing to be somebody's turn to do the operation of probe shutter protective device, can smear lubricant with the position that release lever 16 contacts at push rod 15, such as solid oil.
