Description
Technical field
The utility model relates to the device that prevents in a kind of loading device that sample needle from dropping when outage downwards.
Background technology
Multi-channel loading device is the apparatus operating such as document automation management of the dilution, distribution, mixing and the related data that are used for full-automatic sample, reagent, and a plurality of application of sample passages are meant to have a plurality of sample injectors.Multi-channel loading device can be used for all automated fluid application of sample work of processes such as medical test, Food Inspection, biological experiment.For example, medicament high flux screening, biology laboratory, the gene sequencing pre-treatment, preceding PCR, back PCR handle, SPE, liquid-liquid extraction, DNA/RNA separates, automatic protein precipitation operation etc.Specifically mainly comprise: nucleic acid purification; PCR is provided with and purifying; Gene; Protein sequencing is handled; The standardization of sample; The biochip sample preparation; Clone's rapid screening; Crystallization of protein; The gel digestion process; The MALDI-TOF sample treatment; Protein precipitation; Protein purification; ADMET analyzes; Soluble analysis; Mixture is handled; The sample rapid screening; Microwell plate duplicates; Solid phase sample extracts; Liquid phase-liquid phase sample extracts; Cell is cultivated; The ELISA sample treatment; The blood group analyzing and processing; Blood sample compiles processing etc.Chinese invention patent CN101596469A discloses a kind of multi-channel loading device; The sample needle of this multi-channel loading device is installed in the bottom of a travelling carriage through the injection pump seat; Move up and down through the motor-driven travelling carriage, thereby sample needle can be moved back and forth above container and sample.But; When the motor that drives travelling carriage cut off the power supply suddenly, travelling carriage can be with sample needle to drop downwards under the gravity effect, if sample needle impinges upon on the table top; Then can cause damage to equipment; If sample needle strikes on container or the sample, then may produce very serious accident, therefore need a kind of device that prevents that sample needle from dropping when outage of design.
The utility model content
The technical problem that the utility model will solve provides a kind of automatic application of sample rifle simple in structure, that cost is low, safe and reliable anti-lost needle device that cuts off the power supply.
The automatic application of sample rifle of the utility model anti-lost needle device that cuts off the power supply; Comprise at least one reset tension spring; The upper end of said reset tension spring is fixed on the extension spring upper hanging plate; Said extension spring upper hanging plate is fixedly connected on the unit master control borad, and the lower end of said reset tension spring is fixed on the switching master control borad, and the gas-liquid displacement apparatus of said switching master control borad and application of sample rifle is fixedly connected under the unit on the mounting rod; Under the said unit mounting rod relatively on the unit mounting rod slide up and down, mounting rod is fixedly connected with the extension spring upper hanging plate on the said unit.
The automatic application of sample rifle of the utility model anti-lost needle device that cuts off the power supply, wherein said reset tension spring is close stretching spring.
The automatic application of sample rifle of the utility model anti-lost needle device that cuts off the power supply, wherein said reset tension spring is two, secured in parallel is between extension spring upper hanging plate and switching master control borad.
The automatic application of sample rifle of the utility model anti-lost needle device that cuts off the power supply is separately fixed at the top and bottom of reset tension spring on fixing unit master control borad and the movable switching master control borad; Switching master control borad and sample needle all are fixed under the unit that can slide up and down on the mounting rod; When the motor of mounting rod under the driver element cuts off the power supply suddenly; Reset tension spring provides a pulling force that makes progress, the mounting rod bump table top that drops downwards under the anti-stop element.Simultaneously, when mounting rod moved upward under the electric-motor drive unit, the reset tension spring that is stretched can also provide the auxiliary power of lifting that makes progress, and reduced the load of motor.
Below in conjunction with accompanying drawing the automatic application of sample rifle of the utility model anti-lost needle device that cuts off the power supply is described further.
Description of drawings
Fig. 1 is the cut off the power supply front view of anti-lost needle device of the automatic application of sample rifle of the utility model.
The specific embodiment
As shown in Figure 1, the automatic application of sample rifle of the utility model anti-lost needle device that cuts off the power supply comprises that 1, two reset tension spring of two reset tension springs 1 adopts close stretching spring.The upper end of two reset tension springs 1 is fixed on the extension spring upper hanging plate 2; Extension spring upper hanging plate 2 is fixedly connected on the unit master control borad 3; The lower end of reset tension spring 1 is fixed on the switching master control borad 4, and the gas-liquid displacement apparatus 5 of switching master control borad 4 and application of sample rifle is fixedly connected under the unit on the mounting rod 6, and sample needle 8 is fixedly mounted on the lower end of mounting rod 6 under the unit through injection pump seat 9; Under the unit mounting rod 6 relatively on the unit mounting rod 7 slide up and down, mounting rod 7 is fixedly connected with extension spring upper hanging plate 2 on the unit.
When the motor of mounting rod under the driver element 6 10 outage suddenly, reset tension spring 1 provides a pulling force that makes progress, and mounting rod 6 is being with the sample needle 8 bump table top that drops downwards under the anti-stop element.Simultaneously, when mounting rod 6 moved upward under motor 10 driver elements, the reset tension spring 1 that is stretched can also provide the auxiliary power of lifting that makes progress, and reduced the load of motor 10.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection domain of the utility model claims.
