Description

Technical Field

[0001] The utility model relates to the technical field of chemical detection, in particular to a protective device in chemical detection. Background Art

[0002] The protective device in chemical testing is a device used to protect operators and the environment from contamination by harmful chemicals. Its main function is to prevent the leakage or overflow of harmful chemicals during the chemical testing process and protect the safety of operators and the environment.

[0003] The protective gloves of some existing traditional protective devices are fixedly connected to the shell. Although this improves the airtight protection of the device, the gloves may be damaged after being used for too long. The fixed connection structure makes it inconvenient to replace, which affects the later use of the device. At the same time, since the device is relatively closed, the water vapor generated during chemical testing is easy to condense on the observation window, affecting the observation and operation of the operator. If the water vapor drips, it is easy to affect the results of the chemical test. However, since the water vapor is located on the inside of the glass, it is very inconvenient to wipe it during the test, which greatly affects the operator's detection. Utility Model Content

The middle part of the sliding rod 2 is slidably connected with a cleaning component 7 for cleaning water vapor and chemical reagents on the glass. The cleaning component 7 includes a slider 71 for driving a scraper 75, the slider 71 is slidably connected to the sliding rod 2 and there are two of them. The left and right sides of the two sliders 71 are fixedly connected with mounting blocks 72 for mounting pulleys 73. The mounting blocks 72 are internally rotatably connected with pulleys 73 for assisting the sliding of the cleaning assembly 7. The mounting blocks 72 and the pulleys 73 are slidably connected to the sliding rod 2. The lower parts of the two sliders 71 are commonly fixedly connected with a scraper 75 for scraping off water vapor on the glass and splashed chemical reagents. The bottom surface of the scraper 75 is fixedly connected with a mounting strip 76 made of plastic with a certain elasticity. The lower part of the mounting strip 76 is movably connected with a water absorption plate 77 for absorbing water vapor and chemical reagents to prevent them from falling. The lower part of the mounting strip 76 is provided with a mounting groove 761 adapted to the water absorption plate 77 for mounting the water absorption plate 77. The top surfaces of the two sliders 71 are fixedly connected with pull blocks 74 for pulling the cleaning assembly 7.

[0029] Furthermore, a No. 1 slide groove 21 adapted to the slider 71 is provided in the middle of the sliding rod 2 for assisting the sliding of the slider 71. The No. 1 slide groove 21 is slidably connected to the slider 71. A No. 2 slide groove 22 adapted to the mounting block 72 is provided on the left and right sides of the No. 1 slide groove 21 for assisting the sliding of the mounting block 72. The No. 2 slide groove 22 is slidably connected to the mounting block 72.

The No. 3 slide groove 23 is slidably connected to the pulley 73.

[0030] In order to facilitate the replacement of the gloves 8, three tooth grooves 52 are opened on the front side of the inner wall of the fixing ring 5 to assist in fixing the connecting ring 6, and four card slots 51 are opened on the rear side of the inner wall of the fixing ring 5 to assist in the installation of the connecting ring 6.

[0031] Furthermore, the front side of the outer wall of the connecting ring 6 is fixedly connected with three convex tooth rings 61 that are adapted to the tooth groove 52 and are used for fixing the two. The convex tooth rings 61 are movably connected to the tooth groove 52.

[0033] In the present invention, when in use, the door on the rear side of the shell 1 is opened, the chemical detection supplies to be used are placed in the shell 1, and then the door on the rear side of the shell 1 is closed. The user puts both hands into the gloves 8 to perform chemical detection. When water vapor is generated due to the chemical reaction, the observation window No. 2 3 is affected by the generated water vapor, or when the chemical reagent splashes and stains the observation window No. 2 3, it is only necessary to pull the pull blocks 74 on both sides, and the pull blocks 74 drive the slider 71 connected thereto to slide in the No. 1 slide groove 21. The slider 71 will also drive the mounting blocks 72 on both sides to slide in the No. 2 slide groove 22, and the pulley 73 connected to the mounting blocks 72 will also slide in the No. 3 slide groove 23. Through the movement of the sliders 71 on both sides , it will drive the scraper 75 connected thereto to clean the water vapor or contaminated reagent on the glass of the No. 2 observation window 3. The cleaned water vapor or reagent will fall on the water absorption plate 77 and be absorbed by it. When the water absorption plate 77 needs to be replaced after being used for a period of time, it only needs to be pulled out of the installation groove 761, and then the new water absorption plate 77 is pressed into the installation groove 761. When the glove 8 is damaged or needs to be replaced after a period of time, it is only necessary to rotate the connecting ring 6, the L-shaped clamping block 62 withdraws from the clamping groove 51, and the convex tooth ring 61 is rotated out of the tooth groove 52, so that the glove 8 to be replaced can be separated from the shell 1. When a new glove 8 needs to be installed, it is only necessary to clamp the L-shaped clamping block 62 into the clamping groove 51, and the convex tooth ring 61 is rotated into the tooth groove 52.
