Description

Technical Field

[0001] The utility model relates to the technical field of spectrometers, in particular to a handheld spectrometer. Background Art

[0002] A spectrometer is an instrument used to accurately measure the angle of light deflection. It can use various principles to separate a mixed light beam into multiple pure light beams and is generally used for spectral analysis. Photodetectors such as photomultiplier tubes are used to measure the intensity of spectral lines at different wavelengths. Its structure consists of an entrance slit, a dispersion system, an imaging system and one or more exit slits. The electromagnetic radiation of the radiation source is separated into the required wavelength or wavelength region by a dispersion element, and the intensity is measured at the selected wavelength.

[0003] Carbon black, as a black particle composed of carbon, has good dyeing, wear resistance, corrosion resistance and conductivity, so it has been widely used in the fields of chemistry, materials, electronics, rubber and plastics. Testing carbon black using a spectrometer may involve measuring the intensity of the wavelength or wavelength region of different components in carbon black, so as to analyze the composition and properties of carbon black. This testing method is of great significance for the quality control, product development and expansion of application fields of carbon black.

[0004] In the prior art, the method of using a handheld spectrometer to detect carbon black is widely popular because the handheld spectrometer is easy to carry and the measuring method is simple. In the existing handheld spectrometer, a cover is usually provided on the bottom detection head to protect the detection head.

[0005] However, the existing cover is often a split design, that is, it is separated from the measuring instrument body; when in use, the cover needs to be removed from the detection head and then put back after use; therefore, during frequent use, the user may easily forget to put the cover back in time after use, resulting in the loss of the cover, which in turn makes the detection head vulnerable to damage. Utility Model Content

[0006] The purpose of this utility model is to provide a handheld spectrometer to solve the following technical problems:

[0007] How to prevent the bottom cover of a handheld spectrophotometer from being lost during use.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-2 The utility model is a handheld spectrometer, including a spectrometer body 100, wherein a detection head 101 is provided at the bottom of the spectrometer body 100 for aligning on the plane of a carbon black body; the spectrometer body 100 can be a handheld spectrometer commonly used in the prior art, so the specific structure of the spectrometer body 100 will not be described in detail herein.

[0031] See also Figure 3-4A covering mechanism 200 is installed at the lower end of the spectrometer body 100 to protect the detection head 101 at the bottom of the spectrometer body 100; the covering mechanism 200 is composed of a fixed sleeve 201, a movable sleeve 202, a spring 203, a cover body 204, a pull ring 205, a ball 206, a limit block 207, a magnetic block 1 208 and a magnetic block 209, wherein the fixed sleeve 201 is a square enclosed kit with upper and lower openings, and its inner circle size is consistent with the outer circle size of the lower end of the spectrometer body 100, and the fixed sleeve 201 is fixedly arranged at the lower end of the spectrometer body 100; a slot connected as an integral body is opened in a circle at the bottom of the fixed sleeve 201; the movable sleeve 202 is also It is a square enclosed kit with upper and lower openings, and the thickness of the movable sleeve 202 is slightly smaller than the slot width of the slot. The upper end of the movable sleeve 202 is slidably inserted into the slot, and a compressible space is formed between the upper end of the movable sleeve 202 and the slot; there are 4 springs 203, and the four springs 203 are evenly distributed in the compressible space; for each spring 203, its upper end is fixedly connected to the top wall of the slot, and the lower end is fixedly connected to the upper end of the movable sleeve 202; when the movable sleeve 202 moves upward in the slot, the spring 203 will produce elastic deformation, and when the force of the movable sleeve 202 moving upward in the slot disappears, then under the elastic action of the spring 203, the movable sleeve 202 will return to its original position downward.

[0032] It should be noted that there is no specific limit to the number of springs 203. In other embodiments, the number of springs 203 may be other, as long as the requirements of uniform arrangement and elasticity are met.

[0033] Under normal conditions, the bottom of the movable sleeve 202 exceeds the detection head 101; a rectangular through hole is provided on the right side of the movable sleeve 202, and a rectangular groove corresponding to the through hole is provided on the inner wall on the left side of the movable sleeve 202, and the through hole and the groove have the same horizontal height; the cover 204 is slidably inserted into the through hole, and the pull ring 205 is installed at the center of the right side of the cover 204 to pull the cover 204. The first magnetic block 208 is installed on the left side of the cover 204, and the second magnetic block 209 is installed on the inner wall of the groove; under normal conditions, the left end of the cover 204 is inserted into the groove, and the first magnetic block 208 and the second magnetic block 209 have opposite magnetic properties, so they will attract each other, thereby fixing the cover 204, so that the cover 204 and the movable sleeve 202 form a closed space, and the detection head 101 is located in the closed space, so it can be protected.

[0034] A limit block 207 is installed at the left end of the lower side of the cover 204; when the spectrophotometer body 100 needs to be used for detection, the cover 204 only needs to be pulled to the right through the pull ring 205, so that the left end of the cover 204 is disengaged from the groove and moves to the right until the detection head 101 is completely exposed; when pulled to the rightmost side, the limit block 207 abuts against the left side of the through hole, which can prevent the cover 204 from being completely pulled out, which is conducive to preventing the cover 204 from slipping off the movable sleeve 202.

[0035] Furthermore, in order to prevent the detection head 101 from being damaged by repeated friction when it moves on the carbon black during the measurement process, a buffer ring 102 is installed on a circle at the bottom of the detection head 101. The buffer ring 102 is made of silicone material and can play a buffering role to prevent the detection head 101 from directly contacting the carbon black, thereby protecting the detection head 101; at the same time, when the cover body 204 is in a closed state, the buffer ring 102 can prevent the cover body 204 from directly touching the detection head 101, so as to prevent the cover body 204 from damaging the detection head 101.

[0036] Furthermore, a plurality of balls 206 are evenly arranged at the bottom of the movable sleeve 202; when the spectrophotometer body 100 is used for measurement, the cover 204 is first pulled rightward through the pull ring 205 until the limit block 207 is blocked on the left side of the through hole. At this time, the cover 204 is opened and the detection head 101 is exposed. Then, the spectrophotometer body 100 is held and the movable sleeve 202 is pressed on the carbon black body. The spectrophotometer body 100 is pressed downward to drive the fixed sleeve 201 to move downward, and the movable sleeve 202 moves upward in the slot relatively, thereby compressing the spring 203; when the movable sleeve 202 moves upward to the point where the balls 206 at the bottom are flush with the buffer ring 102, the downward pressure is stopped, and the detection head 101 is moved for aiming. During the movement, the balls 206 roll on the carbon black, which can reduce friction, facilitate aiming, and reduce friction damage to the detection head 101 and the buffer ring 102.

[0037] The working principle of this utility model:

[0038] See also Figure 5 When measuring carbon black, first pull the cover 204 to the right through the pull ring 205 until the limit block 207 is blocked on the left side of the through hole. At this time, the cover 204 is opened and the detection head 101 is exposed. Then, hold the spectrophotometer body 100 and press the movable sleeve 202 on the carbon black body. Press the spectrophotometer body 100 downward to drive the fixed sleeve 201 to move downward, and the movable sleeve 202 moves upward in the slot, thereby compressing the spring 203. When the movable sleeve 202 moves upward to the bottom of the ball 206 and the buffer ring 102, stop pressing down, move the detection head 101 for aiming, and then measure.
