Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
Example 1
As shown in figures 1-3, a airtight protection structure of water quality COD detector, including depositing protective frame 1, deposit protective frame 1 inside bottom and placed sample collection bottle 2, the outer wall of 2 front ends of sample collection bottle is equipped with scale mark 3, it has threaded connection groove 4 to run through and open at the top of depositing protective frame 1, it is equipped with threaded connection rod 5 to deposit protective frame 1 and be located the interpolation of threaded connection groove 4, threaded connection rod 5 keeps away from the bottom fixed connection between the one end of depositing protective frame 1 and the adjustment handle 6 both ends, threaded connection rod 5 inserts and is equipped with application of force board 7 below the one end of depositing protective frame 1, the one end fixedly connected with rubber seal lid 8 of threaded connection rod 5 is kept away from to application of force board 7, the inside fixedly connected with rubber seal block 9 of application of force board 7 one end is kept away from to.
The distance between the inner wall and the outer wall of the storage protective frame 1 is equal to the distance between the inner wall of the rubber sealing cover 8 and the outer wall of the rubber plugging block 9, and sealing is facilitated.
The external diameter size of threaded connection pole 5 and the internal diameter size phase-match of threaded connection groove 4, and threaded connection pole 5 through threaded connection groove 4 with deposit protective frame 1 threaded connection, the convenient decline makes it sticiss application of force board 7.
The distance between the top and the bottom of the threaded connecting rod 5 is equal to the distance between the top end of the inner wall of the storage protective frame 1 and the top of the sample collecting bottle 2, and the compression is convenient.
The inner diameter of the rubber sealing cover 8 is equal to the outer diameter of the storage protective frame 1, and the outer diameter of the rubber plugging block 9 is equal to the inner diameter of the storage protective frame 1, so that the sealing between the rubber sealing cover and the storage protective frame is more compact.
