Abstract
A gene PCR instrument module locking mechanism relates to a component of a PCR instrument. Currently, a positioning mechanism which not only is suitable for placing modules, but also is reliable to lock is lacked. The gene PCR instrument module locking mechanism is axially connected with a handle on a pressure frame component, the axially-connected end of the handle is provided with an outer convex segment, and a spacing segment which is matched with the outer convex segment is arranged on a casing, and the handle has two working state intervals during rotating, the outer convex segment is arranged on the lower side of the spacing segment in the first working state interval, and the outer convex segment leaves off the lower side of the spacing segment in the second working state interval. The gene PCR instrument module locking mechanism achieves convenient conversion of a locking state and an unlocking state through arranging the flexible and smart positioning mechanism, which is reliable to position, and guarantees transportation security.
Description
[technical field]
The utility model relates to the parts of gene-amplificative instrament, specifically is a kind of gene-amplificative instrament module latch mechanism.
[background technology]
Gene-amplificative instrament need to use different modules when carrying out different tests, module is fixed in the press box assembly usually, contains heavier scatterer, and the press box assembly places in the amplification instrument to realize combining of module and the instrument that increases again.In transportation, if the press box assembly in case from amplification instrument housing, can damage even can damage instrument whole instrument.Therefore, need between press box assembly and amplification instrument housing, locating mechanism be set, and need to satisfy the purpose of not only being convenient to that module picks and places but also reliably locking, and lack such locating mechanism at present.
[utility model content]
In order to overcome the above-mentioned defective that exists in the prior art, the utility model provides a kind of gene-amplificative instrament module latch mechanism, to reach the purpose of not only being convenient to that module picks and places but also reliably locking, guarantees transportation safety.
For this reason, the utility model is by the following technical solutions: gene-amplificative instrament module latch mechanism, comprise the press box assembly that contains module, the housing of holding module, it is characterized in that being connected with handle on the described press box assembly, the pivoted connection end of this handle is provided with an outwardly projecting portion, and housing is provided with spacing section that cooperates with outwardly projecting portion, has two working order intervals in the handle rotation process, in the first working order interval, outwardly projecting portion is positioned at spacing section downside; In the second working order interval, outwardly projecting portion leaves spacing section downside.When needs pick and place module, the pull-up handle make its be in the second working order interval just can, spacing section can not hindered moving of outwardly projecting portion; Finish when needing the locking module when picking and placeing, put down handle, it is in the first working order interval, spacing section is stuck in the outwardly projecting portion upside, and the press box assembly can't lifting moving, can not drop out in instrument, thereby guarantee transportation safety.The utility model adopts better simply structure only need rely on moving handle just can finish the change of locking and two states of release, and is very convenient.
As to the improving and replenishing of technique scheme, the utility model is further taked the arbitrary combination of following technical measures or these technical measures:
Described outwardly projecting portion is fan annular, and it is located at the pivoted connection end of handle and is the center of circle with the center of rotation of handle, and spacing section downside is provided with and fans the cambered surface that the ring intrados cooperates.Handle in the rotation process, is close to the outwardly projecting portion inboard for spacing section all the time in the first working order interval like this, and the location is reliable, rotates level and smooth.
Described housing is provided with and fans the guide section that annular outer section extrados matches, and guide section cooperates with spacing section will be fanned the annular outer section and be sandwiched between two cambered surfaces, guarantee that it moves in pre-determined range, reliable operation.
Form an arc groove between described fan annular outer section and the handle pivoted connection end, spacing section shape matches with arc groove, and when locking, spacing section can enter in the arc groove like this, and cooperating between handle and the housing is tightr.
Be respectively equipped with corresponding magnet on described handle and the housing, guaranteed that handle can not break away from housing when locking.
Beneficial effect: the utility model has been realized conveniently changing between locking and two states of release by flexible locating mechanism cleverly is set, and the location is reliable, has guaranteed transportation safety.

Fig. 4 is the local view that amplifies in the B place of Fig. 2.
[embodiment]
Gene-amplificative instrament module latch mechanism as shown in Figures 1 to 4, press box assembly 2 comprises module, is connected with handle 3 on the press box assembly 2, and handle 3 is a pivoted connection end 31 with press box assembly 2 places of being coupling, pivoted connection end 31 is provided with fan annular outwardly projecting portion 4, forms groove 41 between outwardly projecting portion 4 and the pivoted connection end 31.Housing is provided with spacing section 5 and the guide section 6 that cooperates with outwardly projecting portion, and spacing section 5 and guide section 6 are respectively equipped with and fan the cambered surface that annular internal and external cambered surface cooperates, and is respectively equipped with corresponding magnet on handle and the housing.
During locking, push away handle downwards, spacing section 5 enters in the groove 41, and outwardly projecting portion is positioned at spacing section downside, and module just can not deviate from (Fig. 1, Fig. 3) from instrument; Upwards draw handle, outwardly projecting portion leaves spacing section downside, just desirable amplification module (Fig. 2, Fig. 4).
Claims (5)
1, gene-amplificative instrament module latch mechanism, comprise the press box assembly that contains module, the housing of holding module, it is characterized in that: be connected with handle on the described press box assembly, the pivoted connection end of this handle is provided with an outwardly projecting portion, housing is provided with spacing section that cooperates with outwardly projecting portion, have two working order intervals in the handle rotation process, in the first working order interval, outwardly projecting portion is positioned at spacing section downside; In the second working order interval, outwardly projecting portion leaves spacing section downside.
2, gene-amplificative instrament module latch according to claim 1 mechanism, it is characterized in that: described outwardly projecting portion is the fan annular, it is located at the pivoted connection end of handle and is the center of circle with the center of rotation of handle, and spacing section downside is provided with and fans the cambered surface that the ring intrados cooperates.
