Technical Field

[0001] The utility model relates to the technical field of spectrophotometers, in particular to a spectrophotometer used for chemical analysis experiments. Background Art

[0002] Spectrophotometer, also known as spectrometer, is a scientific instrument that decomposes light with complex components into spectral lines. The measurement range generally includes the visible light region with a wavelength range of 380-780nm and the ultraviolet light region with a wavelength range of 200-380nm. Different light sources have their own unique emission spectra, so different luminophores can be used as the light source of the instrument. The spectrophotometer uses a light source that can generate multiple wavelengths, and a series of spectroscopic devices to generate a light source of a specific wavelength. After the light passes through the tested sample, part of the light is absorbed, and the absorbance value of the sample is calculated, which is converted into the concentration of the sample. The absorbance value of the sample is proportional to the concentration of the sample. At present, spectrophotometers are widely used in chemical analysis experiments.

[0003] In order to facilitate the analysis experiment of certain samples, it is necessary to bring a spectrophotometer to the sampling site for on-site detection. However, in the prior art, large-logarithmic spectrophotometers are all large-volume devices, which means that the spectrophotometer can only be picked up or lifted up by staff for transportation, which reduces the portability of the spectrophotometer and affects the use effect of the spectrophotometer. In view of this, we propose a spectrophotometer for chemical analysis experiments. Utility Model Content

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0022] Example 1: A spectrophotometer for chemical analysis experiments, see Figures 1 to 4 , comprising a spectrophotometer body 1, a carrying component 2 and a fixing component 3;

[0023] like Figure 1-4 As shown, the carrying component 2 of this embodiment, when in use, is used to facilitate carrying the spectrophotometer body 1; specifically, the carrying component 2 includes a groove 201, a carrying handle 202, a fixing block 203 and a receiving groove 204; the spectrophotometer body 1 is provided with a groove 201; the carrying handle 202 is inserted into the groove 201; two fixing blocks 203 are symmetrically arranged at both ends of the carrying handle 202; a receiving groove 204 is provided in the fixing block 203, and the end of the carrying handle 202 passes through the receiving groove 204 and is connected to the receiving groove 204 through the fixing component 3. The utility model is provided with a carrying component 2. When the spectrophotometer body 1 needs to be carried, first, the carrying handle 202 is moved so that the carrying handle 202 moves upward in the groove 201 and the receiving groove 204 until the carrying handle 202 is moved to a suitable position by the fixing component 3, and then the carrying handle 202 can be lifted to carry the spectrophotometer body 1. When the carrying handle 202 needs to be hidden, the carrying handle 202 is moved so that the carrying handle 202 moves downward in the groove 201 and the receiving groove 204 until the carrying handle 202 is moved to a suitable position in the groove 201 by the fixing component 3, and the carrying handle 202 is hidden. The utility model can not only facilitate the carrying of the spectrophotometer body 1, but also facilitate the hiding of the carrying handle 202, so as to avoid the carrying handle 202 from being bumped and damaged.

[0024] Specifically, the thickness of the carrying handle 202 is smaller than the depth of the groove 201. The utility model sets the thickness of the carrying handle 202 to be smaller than the depth of the groove 201, so as to provide a buffer space for the carrying handle 202, so that the carrying handle 202 can be moved out of the groove 201.

[0025] Furthermore, the fixing assembly 3 includes a spring 301, a sliding block 302, a movable groove 303, a fixing member 304, a rotating plate 305 and a limit block 306; the spring 301 is arranged in the receiving groove 204, and one end of the spring 301 is fixedly connected to the inner wall of the receiving groove 204; the sliding block 302 is fixedly connected to the other end of the spring 301; wherein the sliding block 302 is slidably matched with the receiving groove 204; a movable groove 303 is provided on one side of the sliding block 302; the fixing member 304 is fixed in the receiving groove 204; the rotating plate 305 is rotatably connected to the fixing member 304 through a rotating shaft; the limit block 306 is fixed on the side of the rotating plate 305 close to the movable groove 303; wherein the limit block 306 is slidably matched with the movable groove 303. The utility model arranges a spring 301, a sliding block 302, a movable groove 303, a fixing member 304, a rotating plate 305 and a limiting block 306, and utilizes the sliding cooperation between the sliding block 302 and the accommodating groove 204, the rotating cooperation between the rotating plate 305 and the fixing member 304, the sliding cooperation between the limiting block 306 and the movable groove 303 and the elastic action of the spring 301, so that not only the position of the carrying handle 202 in the groove 201 can be fixed, but also the position of the carrying handle 202 moved out of the groove 201 can be fixed, thereby improving the practicality of the utility model.

[0026] Furthermore, the movable groove 303 is in a heart-shaped structure, and the outer wall and inner wall of the heart-shaped tip and the inner concave end of the movable groove 303 are arranged alternately, and the outer wall arc of the heart-shaped bottom edge of the movable groove 303 is larger than the inner wall arc. The utility model facilitates fixing the carrying handle 202 in different positions by arranging the movable groove 303 in a heart-shaped structure, and arranging the outer wall and inner wall of the heart-shaped tip and the inner concave end of the movable groove 303 alternately, and arranging the outer wall arc of the heart-shaped bottom edge of the movable groove 303 to be larger than the inner wall arc.

[0027] It is worth noting that the length dimension of the spring 301 is greater than the height dimension of the sliding block 302; when the stop block 306 slides to the concave end of the movable groove 303, the top surface of the carrying handle 202 is flush with the spectrophotometer body 1; when the stop block 306 slides to the side end of the movable groove 303, the inner bottom surface of the carrying handle 202 does not contact the inner wall of the groove 201; when the stop block 306 slides to the tip of the movable groove 303, the end surface of the sliding block 302 contacts the inner top surface of the receiving groove 204. The utility model sets the length dimension of the spring 301 to be greater than the height dimension of the sliding block 302, so as to ensure that when the position of the carrying handle 202 is fixed, the spring 301 still has space to shrink.

[0028] Working principle: When the spectrophotometer body 1 needs to be carried, first, the carrying handle 202 is pressed to slide the carrying handle 202 downward, so that the sliding block 302 slides downward in the receiving groove 204, so that the spring 301 is forced to contract, so that the inner wall of the movable groove 303 squeezes the limit block 306, so that the limit block 306 slides from the concave end of the movable groove 303 to the side end of the movable groove 303, so that the rotating plate 305 rotates with the fixing member 304 through the rotating shaft until the limit block 306 slides to the side end of the movable groove 303. At this time, the carrying handle 202 is released, and the spring 301 is no longer constrained. The spring 301 starts to stretch, so that the sliding block 302 slides upward in the receiving groove 204, so that the carrying handle 202 slides upward, so that the limit block 306 slides from the side end of the movable groove 303 to the tip of the movable groove 303, so that the rotating plate 305 rotates with the fixing member 304 through the rotating shaft until the limit block 306 slides to the tip of the movable groove 303. At this time, the spring 301 is still in a state of contraction under force, so that the position of the sliding block 302 in the receiving groove 204 is fixed, so that the position of the carrying handle 202 is fixed, and the carrying handle 202 can be lifted to carry the spectrophotometer body 1;

[0029] When the carrying handle 202 needs to be hidden, the carrying handle 202 is pressed to slide downward, and the sliding block 302 slides downward in the accommodating groove 204, so that the spring 301 is forced to contract, and the inner wall of the movable groove 303 squeezes the limiting block 306, so that the limiting block 306 slides from the tip of the movable groove 303 to the other side of the movable groove 303, and the rotating plate 305 rotates with the fixing member 304 through the rotating shaft until the limiting block 306 slides to the other side of the movable groove 303. At this time, the carrying handle 202 is released, and the spring 301 is no longer stressed, and the carrying handle 202 begins to be lifted. The spring 301 is stretched to make the sliding block 302 slide upward in the receiving groove 204, and the carrying handle 202 slide upward, so that the limit block 306 slides from the other side end of the movable groove 303 to the concave end of the movable groove 303, and the rotating plate 305 rotates with the fixing member 304 through the rotating shaft until the limit block 306 slides to the concave end of the movable groove 303. At this time, the spring 301 is in a stressed contracted state, so that the position of the sliding block 302 in the receiving groove 204 is fixed, and the position of the carrying handle 202 is fixed in the groove 201, thereby completing the hiding of the carrying handle 202.
