[0003] The working principle of raman spectrometer is that when a monochromatic light with frequency v0 is irradiated on the sample, the molecules can cause the incident light to scatter. Most of the light only changes the direction of light propagation, so the transmission light through the molecules has the same frequency as the incident light, which is called Rayleigh scattering at this time;There is also scattered light, which not only changes the direction of propagation, but also changes the frequency of the scattered light, which is different from the frequency of the excitation light (incident light), so it is called Raman scattering. Raman scattering is caused by the change of molecular polarizability (change of electron cloud). Raman shift depends on the change of molecular vibration energy level, and different chemical bonds or groups have characteristic molecular vibration, ΔE reflects the change of specified energy level, so the corresponding Raman shift is also characteristic. This is the basis for Raman spectroscopy to be used for qualitative analysis of molecular structure.

[0036] The embodiments of the present application will be described in detail by specific embodiments, and those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in the specification.

[0037] Please refer to Figures 1 to 6 It should be understood that the structure, proportion, size, etc. shown in the drawings attached to the specification are only used to cooperate with the content disclosed in the specification for those skilled in the art to understand and read, and are not used to limit the implementation conditions of the present application, so they do not have technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the present application, should still fall within the scope of the technical content disclosed by the present application. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" in the specification are only for the convenience of clear description, and are not used to limit the scope of the present application, and the change or adjustment of the relative relationship without substantial change of the technical content is also considered as the scope of the present application.

[0038] As Figure 1 shown, the present application provides a bin door and trigger device of a Raman spectrum detection device, which comprises an outer shell 1, a bin door mechanism 2 and a trigger mechanism 3. The inside of the outer shell 1 is provided with a laser emitter, a Raman head, a Raman analyzer and a mainboard for controlling and powering the above-mentioned devices. The outer shell 1 is used for Raman spectrum detection of samples. At the same time, the outer shell 1 has a bin opening for placing samples, so that the samples can be placed into the inside of the device. The bin door mechanism 2 is arranged at the bin opening of the outer shell 1 and can be used to seal the bin opening of the outer shell 1. When the sample is detected by Raman spectrum, the bin door mechanism 2 seals the bin opening of the outer shell 1, which can effectively avoid the interference of the external environment on the detection result. The bin door mechanism 2 is provided with a rebound component to pull the bin door mechanism 2 to realize the normally closed state of the bin opening of the outer shell 1, which is used to return to the initial state after the bin door mechanism 2 loses pressure to seal the bin opening of the outer shell 1. The trigger mechanism 3 is arranged inside the outer shell 1, and the trigger mechanism 3 can push the bin door mechanism 2 to open the bin opening of the outer shell 1, so as to facilitate the placement of the sample in the inside of the outer shell 1.

[0039] AsFigure 2 and Figure 3 As shown, in some embodiments, the compartment door mechanism 2 of this utility model includes a sealing cover 201, and a hinge seat 202 is provided on the bottom edge of the sealing cover 201. A connecting shaft 203 passes through the axis of the hinge seat 202. The connecting shaft 203 is connected to the compartment opening of the outer shell 1 so that the sealing cover 201 can rotate radially along the connecting shaft 203.

[0040] With the above technical solution, when the triggering mechanism 3 is driven, it will apply an outward pushing force to the sealing cover 201. At this time, because the bottom hinge seat 202 and the connecting shaft 203 are hinged together with the outer shell 1, the sealing cover 201 will rotate about the connecting shaft 203 as the axis, exposing the opening of the outer shell 1, which facilitates the placement and removal of samples.

[0041] A door-closing torsion spring 204 is installed on the connecting shaft 203 to provide a spring-loaded force to the sealing cover 201, which is the spring-loaded component mentioned above. The spring-loaded force provided by the door-closing torsion spring 204 can pull the sealing cover 201 to close the opening of the outer shell 1. When the trigger mechanism 3 retracts into the outer shell 1, the sealing cover 201 will gradually and automatically close the opening of the outer shell 1 under the action of the door-closing torsion spring 204, without the need for additional operation by personnel.

[0042] Specifically, one end of the closing torsion spring 204 of this invention abuts against the inner wall of the sealing cover 201, and the other end abuts against the bottom of the outer casing 1. At this time, the closing torsion spring 204 is limited by the outer ring and will not shift due to force. At the same time, the closing torsion spring 204 can drive the sealing cover 201 to be in a normally closed state when it is naturally stretched. When the closing torsion spring 204 is compressed, it will always apply a rebound force to the sealing cover 201, and drive the sealing cover 201 back to the closed state after the pressure is removed.

[0043] like Figure 4 As shown, in some embodiments, the sealing cover 201 of this invention has a torsion spring retaining buckle 205 on the side facing the opening of the outer casing 1. The torsion spring retaining buckle 205 is used to fix the end of the closing torsion spring 204. In the naturally stretched state, the end of the closing torsion spring 204 cooperates with the torsion spring retaining buckle 205 to apply a resetting force to the sealing cover 201. Furthermore, the torsion spring retaining buckle 205 limits the end of the closing torsion spring 204, preventing the closing torsion spring 204 from sliding on the outer surface of the connecting shaft 203, which would cause the sealing cover 201 to be not centrally stressed.

[0044] like Figure 4As shown in the drawings, in some embodiments, the utility model discloses a sealing cover 201 is provided with reinforcing ribs 206 on both sides of the one side of the shell body 1, and the reinforcing ribs 206 can effectively increase the structural strength of the sealing cover 201. Meanwhile, the two reinforcing ribs 206 can interact with the trigger mechanism 3 to push the sealing cover 201 to rotate and open the opening of the shell body 1, so as to avoid the direct contact between the trigger mechanism 3 and the inside of the sealing cover 201, which can cause damage to the relatively weak sealing cover 201.

[0045] As shown in the drawings, Figure 4 In some embodiments, the utility model discloses that each reinforcing rib 206 comprises a contact frame 2061, which is arranged along the inside of the sealing cover 201, and the side of the contact frame 2061 facing the trigger mechanism 3 is made of wear-resistant material. The side of the contact frame 2061 is provided with a secondary rib plate 2062, which can support the contact frame 2061. The secondary rib plate 2062 is arranged to further improve the strength of the sealing cover 201 and the contact frame 2061. Because the contact frame 2061 will be directly subjected to the pressure of the trigger mechanism 3, the contact frame 2061 is prone to deformation. Meanwhile, the connection between the contact frame 2061 and the sealing cover 201 is linear connection, and the stress point is relatively concentrated. When the contact frame 2061 is stressed, the connection between the sealing cover 201 and the contact frame 2061 is prone to damage.

[0046] As shown in the drawings, Figure 5 and Figure 6 In some embodiments, the utility model discloses that the trigger mechanism 3 comprises a driving component 301 and two guide rails 302, and the driving component 301 is arranged at the end portion between the two guide rails 302. The guide rail 302 is provided with a connecting slider 303, and the output shaft of the driving component 301 is provided with a power transmission component 304, which can drive the connecting slider 303 to move along the axial direction of the guide rail 302. In a specific embodiment, the power transmission component 304 uses a belt supported at both ends as a power transmission, and a chain, a toothed plate or a synchronous belt can be used in actual production.

[0047] In the above structure, the driving component 301 is used to realize power transmission, so as to drive the connecting slider 303 to move on the surface of the guide rail 302 by driving the power transmission component 304. In order to improve the accuracy of the driving of the driving component 301, the driving component 301 is a device capable of accurately controlling torque, such as a servo motor. When the connecting slider 303 moves towards the sealing cover 201, the connecting slider 303 can push the sealing cover 201 to rotate, so as to open the opening of the shell body 1.

[0048] It needs to be noted that the utility model connects the slide block 303 with the sample rack 305, and the sample rack 305 can move along with the movement of the slide block 303. The side of the sample rack 305 extends to the mouth of the shell body 1 and exceeds the edge of the slide block 303. The purpose of the design is that when the slide block 303 is near the mouth of the shell body 1, the sample rack 305 has already extended to the outside of the mouth of the shell body 1, so that the opening of the sealing cover 201 can be maximized. After the sample rack 305 pushes the sealing cover 201 to the maximum opening angle, the sealing cover 201 is turned to the bottom of the sample rack 305, so that the sample can be conveniently placed and taken out. In addition to turning the sealing cover 201, the sample rack 305 is also used to pull the sample hole plate and drive the sample hole plate to enter the predetermined position in the shell body 1 or push the sample hole plate out of the shell body 1.

[0049] It needs to be noted that the utility model connects the slide block 303 with the sample rack 305, and the sample rack 305 can move along with the movement of the slide block 303. The side of the sample rack 305 extends to the mouth of the shell body 1 and exceeds the edge of the slide block 303. The purpose of the design is that when the slide block 303 is near the mouth of the shell body 1, the sample rack 305 has already extended to the outside of the mouth of the shell body 1, so that the opening of the sealing cover 201 can be maximized. After the sample rack 305 pushes the sealing cover 201 to the maximum opening angle, the sealing cover 201 is turned to the bottom of the sample rack 305, so that the sample can be conveniently placed and taken out. In addition to turning the sealing cover 201, the sample rack 305 is also used to pull the sample hole plate and drive the sample hole plate to enter the predetermined position in the shell body 1 or push the sample hole plate out of the shell body 1.

[0050] As shown in Figure 1 and Figure 5 In some embodiments, the top of the sample rack 305 is provided with a groove, and the groove is used for limiting the sample hole plate. The sample hole plate can be prevented from deviating during the movement of the sample rack 305. After the placement position of the sample hole plate is limited, the coordinate points of the holes on the sample hole plate are also determined, so that the Raman head in the shell body 1 can accurately overlap the holes for detection.

[0051] The utility model is used as follows during use:

[0052] When the sample is placed, the control button outside the shell body 1 is controlled to drive the driving part 301, so that the driving part 301 drives the power transmission part 304 to pull the slide block 303 to the position of the mouth of the shell body 1, at this time, the sample rack 305 installed on the slide block 303 moves to press the reinforcing rib 206;

[0053] After the reinforcing rib 206 is pressed, the reinforcing rib 206 drives the sealing cover 201 to rotate around the connecting shaft 203 under the action of the pressure, so that the mouth of the shell body 1 is gradually opened, and the sealing cover 201 is finally below the sample rack 305;

[0054] After the stability of the hole plate with the sample is determined, the sample stage 305 is driven to move reversely by the driving part 301 controlled by the control button outside the outer shell 1, so that the sample stage 305 is gradually recovered to the inside of the outer shell 1;

[0055] At this time, the sealing cover 201 is bounced back and gradually closes the opening of the outer shell 1 due to the elasticity of the door closing torsion spring 204;

[0056] After the detection of the sample in the hole plate is completed, the sealing cover 201 is opened by the sample stage 305 driven by the above steps, and the sample is taken out, and finally the sample stage 305 is recovered to close the opening of the outer shell 1.

[0057] In summary, the door and the trigger device of the Raman spectrum detection device of the utility model, by setting the door mechanism 2 at the opening of the outer shell 1, and setting the bounce part on the door mechanism 2 to make the door mechanism 2 in the normally closed state, at the same time, setting the trigger mechanism 3 in the inside of the outer shell 1, when the trigger mechanism 3 is driven, the door mechanism 2 is pushed out from the inside of the outer shell 1, the opening of the outer shell 1 is opened, so as to facilitate the placement and taking out of the sample, and after the trigger mechanism 3 is recovered to the inside of the outer shell 1, the bounce mechanism on the door mechanism 2 drives the door mechanism 2 to return to the initial state to seal the opening of the outer shell 1, the effect of convenient use is achieved.

[0058] The utility model discloses a sealing cover 201 is set to the reinforcing rib 206 on one side of the opening of the outer shell 1, when the sample stage 305 pushes the sealing cover 201, first contact with the reinforcing rib 206, avoid the direct friction of the sealing cover 201 and the sample stage 305 and lead to the abrasion of the sealing cover 201, and the reinforcing rib 206 can increase the structural strength of the sealing cover 201, the effect of improving the service life is achieved.

[0059] The utility model discloses a sample stage 305 is set, and the recess is set on the sample stage 305, and the recess can be used for limiting the hole plate for storing the sample, when the sample stage 305 pushes the sealing cover 201, the hole plate can be conveniently placed and taken out, and the convenience of the device is further improved.

[0060] Therefore, the utility model effectively overcomes the various shortcomings in the prior art and has high industrial utilization value.

[0061] The above embodiments only exemplarily illustrate the principles and effects of the present application, and are not used to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the present application should be covered by the claims of the present application.
