DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in this embodiment, a sampling device for VOC detection equipment includes a base plate 1, a fixed plate 7 is fixedly connected to the top of the base plate 1, two second vertical plates 9 are fixedly connected to the top of the fixed plate 7, a lifting assembly is arranged between the two second vertical plates 9, a displacement plate 12 is arranged on the top of the lifting assembly, a sampler 18 is rotatably connected to the top of the displacement plate 12, a filter box 11 is fixedly connected to the top of the displacement plate 12, a mounting plate 23 is slidably connected to the inside of the filter box 11, a filter screen 21 is arranged inside the mounting plate 23, a hose 10 is arranged between one side of the sampler 18 and the top of the filter box 11, a fan 17 is fixedly installed on the top of the displacement plate 12, a detector 13 is fixedly installed on the top of the displacement plate 12, a connecting pipe is arranged between the fan 17, the detector 13 and the filter box 11, a fixed block 24 is fixedly connected to one side of the filter box 11, a slide groove 25 is opened inside the fixed block 24, a limiting assembly is arranged inside the slide groove 25, and a handrail 15 is fixedly connected to the top of the base plate 1.

[0022] First, by pushing the armrest 15, the universal wheel at the bottom of the bottom plate 1 is driven to move, so that the equipment can be conveniently moved to facilitate air detection at different positions. Then, according to the air detection at different heights, the lifting component is started to operate, the displacement plate 12 is driven to adjust the height and the height of the sampler 18 is driven to adjust the height. In this way, the height of the sampler 18 can be adjusted more conveniently, thereby increasing the practicality of the device. Then, by starting the fan 17, the external air enters the hose 10 through the pipeline of the sampler 18, and then enters the filter box 11. The air is filtered through the filter 21, and then enters the detector 13 through the connecting pipe for detection. In this way, dust can be prevented from entering the detector 13 with the air, thereby affecting the accuracy of the detection. Then, when the filter 21 is replaced, the fixing of the mounting plate 23 can be released by toggling the limit assembly, and the filter 21 can be pulled out of the filter box 11 by pulling the handle for replacement. Then, when installing the filter 21, it is only necessary to insert the mounting plate 23 into the filter box 11 to complete the automatic fixing through the limit assembly, thereby increasing the installation efficiency of the device.

[0023] like Figure 1-Figure 4 As shown, the lifting assembly includes a bidirectional screw rod 6, which is rotatably connected between two second vertical plates 9, wherein a motor 4 is fixedly installed on one side of one of the second vertical plates 9, and one end of the output shaft of the motor 4 is fixedly connected to one end of the bidirectional screw rod 6. The lifting assembly also includes two first vertical plates 2, wherein a sliding rod 3 is fixedly connected between the two first vertical plates 2, and a displacement block 8 is movably sleeved on the outer side of the sliding rod 3. A threaded groove is provided inside the side of the displacement block 8 away from the sliding rod 3 and is threadably connected to the outer side of the bidirectional screw rod 6, and a connecting rod 5 is rotatably connected between the top of the displacement block 8 and the bottom of the displacement plate 12.

[0024] When adjusting the height of the sampler 18, the output shaft of the starting motor 4 is rotated to drive the bidirectional screw 6 to rotate and at the same time drive the displacement block 8 to slide on the outside of the slide rod 3, and the movement of the displacement block 8 is limited by the slide rod 3. Then the displacement block 8 moves to drive the connecting rod 5 to rotate and at the same time lift the displacement plate 12, thereby adjusting the height of the sampler 18.

[0025] like Figure 1-Figure 4 As shown, the limit assembly includes a slider 14, which is slidably connected to the inside of the slide groove 25, and a spring 26 is fixedly connected between the top of the slider 14 and the inner wall of the slide groove 25. The limit assembly also includes a clamping block 16, which is slidably connected to the inside of the fixed block 24, and the top of the clamping block 16 is fixedly connected to the bottom of the slider 14. A clamping groove 22 is provided on the top of the mounting plate 23, and a limit groove 20 is penetrated through one side of the fixed block 24. A lever 19 is slidably connected to the inside of the limit groove 20, and one end of the lever 19 is fixedly connected to one side of the slider 14.

[0026] When releasing the fixation of the mounting plate 23, the lever 19 is moved to slide inside the limit groove 20 while driving the slider 14 to slide inside the slide groove 25, and then the block 16 is driven to disengage from the inside of the groove 22, and then the fixation of the mounting plate 23 is released. When installing the mounting plate 23, one side of the mounting plate 23 contacts the inclined surface of the block 16, thereby driving the block 16 to move and the slider 14 to move to compress the spring 26. When the groove 22 on one side of the mounting plate 23 moves to the bottom of the block 16, the reaction force of the spring 26 drives the slider 14 to move and drives the block 16 to enter the groove 22, thereby completing the fixation of the mounting plate 23.

[0027] The utility model provides a sampling device for VOC detection equipment, and the specific working principle is as follows: first, by pushing the handrail 15, the universal wheel at the bottom of the bottom plate 1 is driven to move, so that the equipment can be conveniently moved to facilitate air detection at different positions, and then according to the air detection at different heights, the output shaft of the motor 4 is started to rotate to drive the bidirectional screw rod 6 to rotate and drive the displacement block 8 to slide on the outside of the slide bar 3, and the movement of the displacement block 8 is limited by the slide bar 3, and then the displacement block 8 moves to drive the connecting rod 5 to rotate and lift the displacement plate 12, so as to adjust the height of the sampler 18, and then, the fan 17 is started and the external air enters the hose 10 through the pipeline of the sampler 18, and then enters the filter box 11 The air is filtered through the filter 21 and then enters the detector 13 through the connecting pipe for detection. Finally, the lever 19 is toggled to slide in the limit groove 20 and the slider 14 is driven to slide in the slide groove 25, and then the block 16 is driven to disengage from the slot 22, and then the fixing of the mounting plate 23 is released. When installing the mounting plate 23, one side of the mounting plate 23 contacts the inclined surface of the block 16, thereby driving the block 16 to move and the slider 14 to move to compress the spring 26. When the slot 22 on one side of the mounting plate 23 moves to the bottom of the block 16, the reaction force of the spring 26 drives the slider 14 to move and drives the block 16 to enter the slot 22, thereby completing the fixing of the mounting plate 23.
