DETAILED DESCRIPTION
[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.
[0021] Reference Figure 1-4 , an atomic absorption spectrophotometer, including a spectrophotometer body 1, a placement structure 2 is provided on the spectrophotometer body 1, the placement structure 2 includes a placement frame 201, the placement frame 201 is detachably installed on the spectrophotometer body 1 through a fixing structure 6, a placement plate 202 is slidably connected to the placement frame 201, an elastic structure 3 for adjusting the placement plate 202 is provided on the placement frame 201, a collecting bottle body 4 is placed inside the placement plate 202, a port of the collecting bottle body 4 is plugged into a rubber pad 7 provided inside the placement frame 201, and a ventilation port on the surface of the spectrophotometer body 1 and a ventilation port on the surface of the placement frame 201 are provided with a connecting hose 5 for communication.
[0022] Specifically, the elastic structure 3 includes a spring 301 and a telescopic rod 303. Two springs 301 are fixedly connected to the placement rack 201. One end of the spring 301 away from the placement rack 201 is fixedly connected to a mounting plate 302. Both mounting plates 302 are fixedly connected to the placement plate 202. Two telescopic rods 303 are fixedly connected to the placement rack 201. One end of the telescopic rod 303 away from the placement rack 201 is fixedly connected to the mounting plate 302. The spring 301 is wound around the telescopic rod 303. By arranging the spring 301, the mounting plate 302 and the telescopic rod 303, with the cooperation of the spring 301, the mounting plate 302 and the telescopic rod 303, the placement plate 202 is always subjected to a force close to the placement rack 201, thereby facilitating the collection bottle body 4 to be inserted into the rubber pad 7, thereby ensuring the sealing between the collection bottle body 4 and the rubber pad 7.
[0023] Specifically, the fixed structure 6 includes a fixed block 601, two fixed blocks 601 are fixedly connected to the spectrophotometer body 1, and a guide block 602 is slidably connected inside the fixed block 601. The two guide blocks 602 are fixedly connected to the placement rack 201. The guide blocks 602 are limited and fixed on the surface of the fixed block 601 by fastening bolts. By setting the fixed block 601 and the guide block 602, it is convenient for the operator to disassemble and assemble the placement rack 201 and the placement plate 202.
[0024] Specifically, the port of the collecting bottle body 4 fits tightly with the rubber pad 7, a pulling block 8 is fixedly connected to the surface of the placement plate 202, a tripod 9 is detachably installed on the bottom end of the spectrophotometer body 1, the shape of the rubber pad 7 is set to a truncated cone, the cross-sectional shape of the fixed block 601 is set to an "L" shape, and the cross-sectional shape of the placement rack 201 is set to a "Z" shape. By setting the rubber pad 7 and setting the shape of the rubber pad 7 to a truncated cone, the sealing of the connection between the collecting bottle body 4 and the placement rack 201 can be ensured. At the same time, because its shape is set to a truncated cone, it is convenient for the port of the collecting bottle body 4 to be inserted into the rubber pad 7, thereby improving the convenience of use for operators.
[0025] When the utility model is used, the spectrophotometer body 1 and the collecting bottle body 4 are first connected through the connecting hose 5, and the operator directly pulls the placement plate 202. When the placement plate 202 is moving, the spring 301 is adjusted through the mounting plate 302. When the placement plate 202 moves to a suitable position, the operator places the collecting bottle body 4 inside the groove on the surface of the placement plate 202, and after releasing the force on the placement plate 202, under the force of the telescopic rod 303, the mounting plate 302 drives the port of the collecting bottle body 4 to be inserted into the rubber pad 7 through the placement plate 202, and the end of the collecting bottle body 4 is tightly fitted with the rubber pad 7, so that the spectrophotometer body 1 is connected with the collecting bottle body 4 through the connecting hose 5 and the placement rack 201.
[0026] When the operator uses the device, if the placement rack 201, the placement plate 202 or the spring 301 is damaged, the operator directly adjusts the fastening bolts on the surface of the two fixed blocks 601 so that the fastening bolts release the limiting fixation of the guide block 602. The operator pulls the placement rack 201 so that the placement rack 201 drives the two guide blocks 602 to release the connection with the two fixed blocks 601, and the placement rack 201 can be directly replaced.
