The working principle of the invention is that during working, the electric telescopic rod 18 extends to drive the driving seat 26 to ascend, so that the first transmission block 29 enters the first transmission seat 25, then the driving motor 34 is started, the driving motor 34 drives the driving wheel 35 to rotate, the driving wheel 35 drives the driven wheel 37 to rotate through the belt 36, so that the transmission shaft 28 drives the first threaded rod 5 to rotate through the first transmission block 29 and the first transmission seat 25 to extend the analyzer body 3 out of the box body 1, then the fixing plate 14 is pulled to enable the rotary column 15 and the fixing block 10 to pass through the supporting groove 9 of the supporting seat 8, then the fixing block 10 rotates 180 degrees, so that the fixing block 10 can not retract under the action of the tension spring 13, and the rotary column 15 and the supporting seat 8 are utilized to support the workbench 2, thereby ensuring the stability of the device during working, protecting the lifting mechanism and prolonging the service life of the device, when not using, driving motor 34 drives the reversal of first threaded rod 5, with the analysis appearance body 3 through elevating system receive into box 1 in, the analysis appearance of not only being convenient for deposits for the analysis appearance is convenient for shift, makes the analysis appearance can not receive outside collision moreover, realizes the protection to the analysis appearance.
When the device needs to be moved, the electric telescopic rod 18 contracts to drive the driving seat 26 to descend, so that the first transmission block 29 is separated from the first transmission seat 25, the second transmission block 30 enters the belt second transmission seat 31, then the driving motor 34 is started, the driving motor 34 drives the driving wheel 35 to rotate, the driving wheel 35 drives the driven wheel 37 to rotate through the belt 36, so that the transmission shaft 28 drives the second threaded rod 32 to rotate through the second transmission block 30 and the second transmission seat 31, so that the base 22 moves downwards, so that the moving wheel 23 is in contact with the ground, so that the device moves, when the device does not move, the driving motor 34 rotates reversely, so that the box body 1 descends, the box body 1 descends to drive the positioning column 38 and the positioning seat 39 to descend, the positioning seat 39 and the positioning suction disc 42 are firstly squeezed out of the ground, then the positioning column 38 descends continuously, so that the piston plate 44 slides in the first cavity 40, so that the air in the suction disc 42 is evacuated through the positioning column 43 and the second cavity 41, so that the suction cup 42 can be tightly sucked to the ground, when the moving wheel 23 is protruded out of the case body 1, the suction cup 42 can be charged with air by the above structure, and the sucking work between the suction cup 42 and the ground can be released.
To sum up, through the structure setting of elevating system, supporting seat 8, column spinner 15 and rotatory piece, when realizing being convenient for accomodate the analysis appearance, guarantee the function of the stability that the analysis appearance used.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
