The working principle and the using process of the invention are as follows: firstly, pulling a handle 203 through a pull groove 205, enabling the handle 203 to rotate by 90 degrees by means of the matching of a connecting groove 204 and a fixed bolt 202, further enabling the handle 203 to be vertical to the upper surface of the control instrument 1, conveniently carrying the control instrument 1 by means of two groups of handles 203, moving the control instrument 1 between two groups of connecting frames 303, enabling a movable ring 307 to compress a first spring 306 to shrink by pushing the movable ring 307, further enabling one end of the connecting frame 303 to be exposed, then installing a connecting column 301 and a limiting block 302 arranged at one end of the control instrument 1 on the connecting frame 303, then loosening the movable ring 307, enabling the movable ring 307 to reset under the action of the first spring 306, enabling a clamping bead 304 arranged on the connecting frame 303 to fall into the connecting column 301 and provided with the limiting groove, and simultaneously installing the limiting block 302 and the connecting frame 303 to enable the control instrument 1 to be installed and fixed, then, by means of the cooperation of the connecting groove 204 and the fixing bolt 202, the carrying handle 203 is rotated by 90 degrees, the carrying handle 203 is moved into the containing groove 201, the film mounted on the control panel of the control instrument 1 is exposed in the chemical production environment for a long time, the chemical production numerical value is adjusted by pressing the control key on the control panel, after long-time use, the attached film is subjected to chemical corrosion, the film needs to be replaced periodically, the control panel is protected, the aging of the control panel caused by the chemical production environment is avoided, the service life is influenced, when the film attached on the control panel of the control instrument 1 is replaced, the movable block 405 is pressed by the pressing block 408, the movable block 405 compresses the second spring 406, the movable block 405 moves in the movable groove 401, and the movable block 405 drives the lug 407 to move in the first through hole 402, make lug 407 and recess 411 separate, and then make shell 409 lose fixedly, then through dismantling shell 409, make outer limiting plate 410 and interior limiting plate 404 separate, get rid of the film that adheres to on control instrument 1 control panel, change new film, then through the cooperation of outer limiting plate 410 and interior limiting plate 404, install shell 409 on control instrument 1, make lug 407 the inside of card income recess 411 once more, fix shell 409, make the film fixed adhere to on control instrument 1 control panel.

Therefore, the chemical control instrument convenient for connection and assembly comprises a control instrument 1, a lifting and accommodating mechanism 2, a connecting mechanism 3 and a film fixing mechanism 4, wherein the lifting and accommodating mechanism 2 is arranged at the top end of the control instrument 1, two ends of the control instrument 1 are connected and fixed with the outside through the connecting mechanism 3, the film fixing mechanism 4 is arranged on one side of a control panel of the control instrument 1, when the control instrument is carried, a lifting handle is pulled through a pull groove, the lifting handle rotates through an angle by means of the matching of a connecting groove and a fixing bolt, the lifting handle is perpendicular to the upper surface of the control instrument, the control instrument is conveniently carried by means of two groups of lifting handles, after the control instrument is carried, installed and fixed, the lifting handle is controlled to rotate through the pull groove to move into the inner part of the accommodating groove, the space occupied by the device is reduced, and when the control instrument is installed and fixed, through promoting the movable ring, make the movable ring compress the first spring and contract, and then make one end of the link expose, then install spliced pole and stopper that control instrument one end set up on the link, then loosen the movable ring, make the movable ring reset under the effect of first spring, make the shelf location card pearl fall to the spliced pole and set up inside the spacing groove, the structure setting of stopper and link simultaneously, make the control instrument after installation fixed, the condition of not taking place to rotate, when changing the film attached to control instrument control panel, through pressing to the pressing block, make the movable block compress the second spring, make the movable block move in the inside of the spacing groove, and then make the movable block drive the lug to move in the inside of first through-hole, make lug and recess separate, and then make the shell lose fixedly, then through dismantling the shell, make outer limiting plate and interior limiting plate separation, get rid of the film of adhering to on control instrument control panel, change new film, then through the cooperation of outer limiting plate and interior limiting plate, install the shell on control instrument, make the lug card go into the inside of recess once more, fix the shell, make the film fixed adhere to on control instrument control panel.
