Abstract
A timer shielding mechanism belongs to a field of special timers for timing a detection time of a biological detection kit, and is characterized in that the mechanism comprises a shielding plate and a fixing plate for fixing the shielding plate, wherein one edge of the shielding plate is provided with a connection rotating shaft provided with a torsion spring to which the fixing plate is connected, the fixing plate is a rectangular sheet metal, two corresponding sides of the fixing plate are provided with connection ear holes for supporting the connection rotating shaft, and both ends of the connection rotating shaft are arranged in the connection ear holes. The timer shielding mechanism is simple in structure, can be used during a whole detection process of the biological detection kit, with a reflective infrared sensor being not influenced by external light sources, and thus guarantees an accurate timing of the timer and meanwhile a normal work of the whole detection process.
Description
Technical field:
The utility model relates to a kind of timer chopping mechanism, and it belongs to the Special time marker field of biological detection reagent kit timing detection time.
Background technology:
In order to improve the detection efficiency of biological detection reagent kit, designed in prior art and the matching used timer of biological detection reagent kit, this timer pallet upper cover can rotate with respect to base, so just can conveniently use whole 12 timing channels.The time of timer can arrange arbitrarily. and when inserting testing cassete, the timer shows screen display is shown green light, and the expression timing starts, timing finishes, and the timer shows screen display is shown red light, and the while audible alarm, the prompting user extracts testing cassete, can carry out the next stage test, improves whole detection efficiency.
Timer of the prior art, be stamped 12 timing channels on pallet, when testing cassete inserts timing channel, timer has judged whether the insertion testing cassete by a reflective infra-red sensor switch, find in the actual use procedure of instrument that at present reflective infrared inductor is easy to be subject to the impact of external light source, and cause the work of instrument to judge by accident, affect the normal use of instrument.
Summary of the invention:
The purpose of this utility model is to provide a kind of infrared induction of avoiding of timer to slip up, and improves the timer chopping mechanism of timer timing accuracy.
A kind of timer chopping mechanism, it is characterized in that it comprises that a shading baffle and one are used for the fixedly fixed head of shading baffle, an end margin at described shading baffle is provided with connection rotating shaft, and also is provided with a torsion spring on connection rotating shaft, and described fixed head is connected on connection rotating shaft.
Be the rectangle sheet metal at described fixed head, be provided with the connection earhole for the support and connection rotating shaft on two limits of its correspondence, the two ends of described connection rotating shaft are placed in and connect earhole.
Be provided with the fixed orifice that is connected for timer on described fixed head.
Another free-ended lower limb of described shading baffle is provided with the plastic plate structure of bending.
Also be provided with the bayonet socket for the torsion spring screens on described baffle plate.
The utility model is simple in structure, can be in the actual use procedure of the whole test of biological detection reagent kit, and reflective infrared inductor is not subjected to the impact of external light source, has guaranteed the accurate timing of timer, has guaranteed again normally carrying out of whole test job simultaneously.

Embodiment:
Below in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, the utility model is further detailed:
In the present embodiment, the utility model comprises that a shading baffle 2 that is used for shading and one are used for the fixedly fixed head 1 of shading baffle, an end margin at described shading baffle 2 is provided with connection rotating shaft 3, and also be provided with a torsion spring 4 on connection rotating shaft 3, described fixed head 1 is connected on connection rotating shaft 3.Be the rectangle sheet metal at described fixed head 1, be provided with the connection earhole 5 for support and connection rotating shaft 3 on two limits of its correspondence, the two ends of described connection rotating shaft 3 are placed in and connect earhole.In order the utility model to be fixed on timer 8 easily, be provided with on described fixed head 1 for the fixed orifice 11 that is connected with timer, during use, be that the utility model is fixed on the position of kit insert port 6 of timer, as shown in Figures 4 and 5.
Described shading baffle 2 another free-ended lower limbs are provided with the plastic plate structure of bending 21.Also be provided with the bayonet socket A. for the torsion spring screens on described baffle plate 2
During the utility model assembling, at first, torsion spring 3 correctly is encased in the middle spring fixed rotating shaft position of baffle plate 2, the torsion that torsion spring adopts is less, just can meet baffle plate and reset.Design can be guaranteed like this: in testing cassete 7 inserts the timing channel process, the retardance sense can in use not appear, when taking out testing cassete, under the synergy of baffle plate 2 self gravitations and torsion spring 2, can reset rapidly, simultaneously torsion spring is arranged on the centre position of baffle plate 2, can guarantee torsion evenly, avoid baffle plate 2 unbalance stress and can't reset.The rotating shaft that installs baffle plate 2 two ends of torsion spring is snapped onto in anti-dazzling screen fixed head 1, note torsion spring elastic arm correct position, be the bayonet socket A that is used for the torsion spring screens that arranges on baffle plate, the function of bayonet socket A is a limit function, and purpose resets on correct position in order to guarantee baffle plate 2.
