The utility model is provided with a lifting rack and a driving motor for driving the lifting rack, and at least one group of Hall elements for detecting the position of the rack and a matched magnet are arranged between the mounting plate and the rack; the controller controls the driving motor to drive the lifting rack to move downwards, when the lifting rack reaches a preset point, the Hall element senses the magnetism of the positioning magnet on the lifting rack, a signal is transmitted to the controller, the controller controls the driving motor to stop, and after sampling and extraction are finished, the controller sends a reverse signal to the driving motor to control the lifting rack to return. The lifting rack can be arranged in the Z-axis direction in the main length direction, and the structure of the product cannot be influenced by the protruding lifting rack in the working movement process.
Description
Technical Field
The utility model relates to an elevating system specifically is elevating system that sampling device used.
Background
When the sampling device is used for sampling, a driving mechanism is needed to control the extraction of the sample solution. The existing lifting structure needs to be matched with a synchronous belt or a screw rod to complete, and enough space needs to be reserved for work and wiring. Along with the development trend of miniaturization and function diversification of the sampling device, the installation space of the driving mechanism of the sampling device is more and more narrow, and the existing conventional driving mechanism cannot meet the requirement.
Disclosure of Invention
The utility model discloses a there is the unsuitable problem of installation space in use in the elevating system who solves current sampling device, provides an elevating system more applicable to sampling device.
The utility model provides a current technical scheme who has the problem be: a lifting mechanism for a sampling device comprises a mounting plate, wherein as an improvement, a lifting rack, a lifting hole or a lifting groove matched with the lifting rack and a driving motor for driving the lifting rack to lift are arranged on the mounting plate, a gear matched with the lifting rack is arranged on the driving motor, and a sliding assembly is arranged between the mounting plate and the lifting rack; the mounting plate and the rack are provided with at least one group of Hall elements for detecting the position of the rack and a magnet matched with the Hall elements, and the driving motor is provided with a controller for receiving signals of the Hall elements and controlling the driving motor.
As a further improvement, the mounting plate is provided with a mounting frame, the sliding block of the sliding assembly is mounted on the mounting frame, and the Hall element is mounted on the mounting frame.
As a further improvement, the Hall element is arranged at the corresponding position of the mounting plate, and the magnet is arranged on the lifting rack.
As a further improvement, the sliding block of the sliding assembly is arranged on the mounting frame, and the sliding rail of the sliding assembly is connected with the lifting rack.
As a further improvement, the Hall element can adjust the installation length.
Compared with the prior art, the utility model has the advantages that the mounting plate is provided with the lifting rack and the driving motor for driving the lifting rack, and at least one group of Hall elements for detecting the position of the rack and the matched magnet are arranged between the mounting plate and the rack; the controller controls the driving motor to drive the lifting rack to move downwards, when the lifting rack reaches a preset point, the Hall element senses the magnetism of the positioning magnet on the lifting rack, a signal is transmitted to the controller, the controller controls the driving motor to stop, and after sampling and extraction are finished, the controller sends a reverse signal to the driving motor to control the lifting rack to return. The lifting mechanism has the beneficial effects that the lifting mechanism is arranged into the lifting rack, the lifting rack can be arranged in the Z-axis direction in the main length direction, and the protruding lifting rack can not influence the product structure during working movement.

Detailed Description
Referring to fig. 1-2, the lifting mechanism for a sampling device of the present embodiment includes a mounting plate 1 capable of being mounted on the sampling device, wherein the mounting plate 1 is provided with a lifting rack 2, a lifting hole or groove 3 engaged with the lifting rack 2, and a driving motor 4 for driving the lifting rack 2 to lift, and the lifting rack 2 is disposed in a Z-axis direction. A gear 21 matched with the lifting rack 2 is arranged on the driving motor 4, and a sliding assembly is arranged between the mounting plate 1 and the lifting rack 2; at least one group of Hall elements 5 for detecting the position of the rack and a magnet 51 matched with the Hall elements are arranged between the mounting plate 1 and the rack, and the driving motor 4 is provided with a controller for receiving signals of the Hall elements 5 and controlling the driving motor 4. During the use, drive motor 4 drives lifting rack 2 downstream through controller control, when reaching lifting rack 2 to the predetermined point, is sensed by hall element 5 and goes up the magnetism of location magnet on lifting rack 2, and hall element 5 transfer signal to controller, and the controller then control drive motor 4 and stop, waits to take a sample after the extraction, and the controller sends the reversal signal to drive motor 4 and controls lifting rack 2 and carry out the playback.
The mounting plate 1 is provided with a mounting frame 10, a sliding block 11 of the sliding assembly is mounted on the mounting frame 10, and the Hall element 5 is mounted on the mounting frame 10.
The hall element 5 is arranged at the corresponding position of the mounting plate 1, and the magnet 51 is arranged on the lifting rack 2.
The sliding block 11 of the sliding component is arranged on the mounting frame 10, and the sliding rail 12 of the sliding component is connected with the lifting rack 2. The Hall element 5 can adjust the installation length, and the lifting position of the lifting rack can be adjusted by finely adjusting the installation length of the Hall element or by adjusting the magnet on the lifting rack.
