Description

Technical Field

[0001] The utility model relates to the technical field of chemical detection, in particular to a chemical detection device with an exposure protection cover. Background Art

[0002] Chemiluminescence is a type of molecular luminescence spectroscopic analysis. It is a trace analysis method that primarily determines the content of the analyte by instrumentally detecting the chemiluminescence intensity of the system based on the principle that the concentration of the analyte in a chemical detection system exhibits a linear quantitative relationship under certain conditions. The essential difference between chemiluminescence and other luminescence analyses lies in the different sources of energy absorbed by the system to produce luminescence. For a system to produce chemiluminescence, it must have both a light radiation reaction that produces a detectable signal and a chemical reaction that can provide sufficient energy to cause the luminescence phenomenon in a single reaction step. Chemiluminescence has a wide range of applications in the analysis of trace metal ions, various inorganic and organic compounds, and in the biological field. When performing chemiluminescence detection, a chemiluminescence detection device is generally required. Existing chemical detection devices detect reaction vessels through optical irradiation, but they lack a structure to protect the light irradiation device from exposure. As a result, the light from the chemical detection device itself easily mixes with external light and irradiates the reaction vessel, which can easily cause the detection value and effect to change, thereby reducing the detection effect of the analyte in the reaction vessel. To address this problem, we propose a chemical detection device with an exposure protection cover to solve this problem. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-5 The present invention provides an embodiment of a chemical detection device with an exposure protection cover, comprising a detection device 1,

[0021] A control panel 2 is provided at the right end of the detection device 1, a protective cover 3 is provided on the upper side of the left end of the detection device 1, a mounting rod 4 is fixedly installed on the lower side of the protective cover 3, an irradiation lamp 5 is installed at the lower end of the mounting rod 4, a rotating component 6 is provided at the lower end of the detection device 1, a plurality of groups of grooves 7 are arranged in a ring on the rotating component 6, an anti-exposure component is movably sleeved on the mounting rod 4, and a connecting component is provided on the lower end of the anti-exposure component and the outer wall of the rotating component 6. This device pulls the anti-exposure component up and down on the mounting rod 4 to cover the irradiation lamp 5 and the rotating component 6, so that the irradiation lamp 5 is separated from the external light when it detects and irradiates the reaction container placed on the rotating component 6, thereby improving the detection effect of the reaction container.

[0022] Furthermore, the anti-exposure component includes a light shield 8, which is movably sleeved on the mounting rod 4. Fixed blocks 10 are fixedly installed at the upper and lower ends of the mounting rod 4. A first spring 11 is sleeved on the lower end of the mounting rod 4. The first spring 11 is located between the upper side of the fixed block 10 at the lower end of the mounting rod 4 and the upper inner wall of the light shield 8. This structure pulls the light shield 8 down to cover the irradiation lamp 5 and the rotating assembly 6. The light shield 8 is connected to the rotating assembly 6 through a connecting assembly to cover the reaction container on the rotating assembly 6. When the light shield 8 is not in use, the light shield 8 is bounced upward and reset by the first spring 11, and the reaction container on the rotating assembly 6 can be taken out.

[0023] Furthermore, multiple groups of partitions 9 are arranged in a ring shape on the inner wall of the light shield 8, and the multiple groups of partitions 9 are located between the multiple groups of grooves 7. This structure separates the internal space of the light shield 8 through the multiple groups of partitions 9, thereby avoiding separating and detecting multiple groups of reaction containers on the rotating component 6 when the light shield 8 is covered on the rotating component 6.

[0024] Furthermore, reflectors are attached to the inner wall of the light shield 8 and the outer walls of the multiple groups of partitions 9, and the opposite ends of the multiple groups of partitions 9 are in contact with the outer wall of the irradiation lamp 5. This structure, based on the reflectors arranged inside the light shield 8 and on the outer walls of the multiple groups of partitions 9, allows the light irradiated by the irradiation lamp 5 to pass through the reflectors on the inner wall of the light shield 8 and the outer walls of the multiple groups of partitions 9 and be concentrated on the reaction vessel, thereby improving the irradiation effect on the reaction vessel.

[0025] Furthermore, the connecting component includes two groups of movable grooves 12, which are symmetrically arranged in the lower end of the light shield 8. A second spring 13 is installed in each of the two groups of movable grooves 12. Limiting blocks 14 are movably installed at the openings of the two groups of movable grooves 12. Limiting grooves 15 are arranged on the left and right sides of the rotating component 6. The two groups of limiting blocks 14 are movably inserted in the two groups of limiting grooves 15. Pull rods 16 are installed on the two groups of limiting blocks 14. This structure can pull the light shield 8 down to cover the irradiation lamp 5 and the rotating component 6 by inserting the two groups of limiting blocks 14 into the two groups of limiting grooves 15, so that the light shield is connected to the rotating component 6, so that the light shield 8 can rotate as the rotating component 6 rotates.

[0026] Furthermore, one end of the two groups of limit blocks 14 inserted in the two groups of limit grooves 15 and the openings of the two groups of limit grooves 15 are both arc-shaped, and the two groups of limit blocks 14 are adapted to the two groups of limit grooves 15. The shape of the one end of the limit blocks 14 inserted in the two groups of limit grooves 15 and the openings of the two groups of limit grooves 15 of this structure makes it possible for the two groups of limit blocks 14 to not get stuck at the openings of the two groups of limit grooves 15 when inserted into the two groups of limit grooves 15, thereby facilitating the rapid insertion of the two groups of limit blocks 14 into the two groups of limit grooves 15.

[0027] Working principle: When the irradiation lamp 5 and the rotating component 6 are protected from exposure, Figure 3 、 Figure 4 and Figure 5As shown, first place the reaction container containing the object to be detected in the multiple groups of grooves 7, and then pull down the light shield 8. When the mounting rod 4 moves down, the light shield 8 squeezes the first spring 11, pulling the two groups of pull rods 16 to drive the two groups of limit blocks 14 to slide into the two groups of movable grooves 12. Then, when the lower end of the light shield 8 is in contact with the outer wall of the rotating component 6, release the two groups of pull rods 16. The two groups of pull rods 16 and the two groups of limit grooves 15 pop out from the two groups of movable grooves 12 under the action of the restoring force of the two groups of second springs 13, and the two groups of limit blocks 14 pop out and are inserted into the two groups of limit grooves 15, so that the light shield 8 can be connected to the rotating component 6. Then, the multiple groups of partitions 9 on the inner wall of the light shield 8 separate the reaction containers placed in the grooves 7, so as to avoid external light interference when the irradiation lamp 5 is irradiated. The above is the entire working principle of the present utility model.

[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
