[0056] A set of sliding grooves 106 are formed on both side walls of the shell cavity 101 close to the middle. There are two sliding grooves 106 in a set, and they are arranged in parallel; the sliding grooves 106 form a 45° angle with the bottom of the shell cavity 101; the dual-channel spectrometer main body 300 further includes a support plate 240, a first acting shaft 241 and a second acting shaft 242. The support plate 240 is fixedly connected to the bottom of the dual-channel spectrometer main body 300.

A second handle 107 is fixedly connected to the back surface of the housing 100 away from the miter joint portion 103, and the set position height is higher than that of the air extraction member 250.

[0060] Specific implementation: When the dual-channel spectrum analyzer main body 300 is not in use, the sliding door 200 is in a closed state. The first part 201 and the third part 203 of the sliding door 200 will be respectively extruded into the second extrusion groove 132 and the third extrusion groove 133 and closely attached under the pulling force of the second pulling rope 2311. And pull the first handle 251 to make the first handle 251 move upward in the air extraction member 250, so that the housing cavity 101 is in a negative pressure state, and the sliding door 200 is compressed towards the dual-channel spectrum analyzer main body 300 and adsorbed on the working port 120. Since the thickness of the second part 202 is greater than 0.2 millimeters of the depth of the second extrusion groove 132, the second part 202 is extruded by the second extrusion groove 132 and closely attached. The bottom of the housing 100 is provided with rollers 110, and through the push of the second handle 107, it can move on the ground, which is convenient to carry out. When it is necessary to open the sliding door 200 to use the dual-channel spectrum analyzer main body 300, compress the second handle 107 downward to restore the air pressure in the housing cavity 101 to the original air pressure, and then start the rotation motor 210 to rotate. The rotating shaft 220 rotates and pulls the first pulling rope 2111 and the third pulling rope 2121. The sliding door 200 overcomes the pulling force of the second pulling rope 2311 under the pulling of the first pulling rope 2111, and the sliding door 200 slides along the channel groove 130 towards the direction of the rotating shaft 220. At this time, the other end of the third pulling rope 2121 drives the supporting plate 240 under the drive of the rotation motor 210, so that the pulleys at both ends of the first acting shaft 241 at the bottom of the supporting plate 240 slide towards the working port 120 in the sliding groove 106. After the dual-channel spectrum analyzer main body 300 passes through the working port 120, the dual-channel spectrum analyzer main body 300 can be used.

[0061] Beneficial effects: Through the actions of the first coiling member 211 and the automatic rope coiling member 231, the first pulling rope 2111 and the second pulling rope 2311 respectively pull the sliding door 200 to slide within the channel groove 130, realizing the closing of the sliding door 200 on the inclined portion 102; the thickness of the second portion 202 is 0.2 mm greater than the depth of the second extrusion groove 132 of the channel groove 130, enabling the second portion 202 of the sliding door 200 to closely adhere to the second extrusion groove 132 of the channel groove 130, improving airtightness; through the air extraction member 250, the housing cavity 101 is in a negative pressure state, improving the airtightness within the housing cavity 101 and preventing dust from entering the housing cavity 101 and affecting the dual-channel spectrum analyzer main body 300; the bottom of the housing 100 is provided with rollers 110, which can be moved on the ground by the push of the second handle 107, facilitating portability for going out.

[0062] Embodiment 2: During the process of carrying it out for going out, when encountering an uneven road surface, jitter will occur, and the pulling force during the closing process of the sliding door 200 is pulled by the pulling force of the second pulling rope 2311. The pulling force of the second pulling rope 2311 on the first portion 201 is relatively small, which may cause the position of the first portion 201 to be easily affected by jitter. The first portion 201 may become loose due to jitter at the connection between the first extrusion groove 131 and the second extrusion groove 132, resulting in the technical problem of reduced airtightness. Therefore, the sliding door 200 is improved, and the following technical solutions are proposed, specifically:

[0063] As Figures 8 to 11 shown, a channel cavity 204 is formed inside the sliding door 200; the channel cavity 204 is further divided into a first through cavity 2041 and a second through cavity 2042; the first through cavity 2041 is close to the first portion 201, the second through cavity 2042 is connected to the first through cavity 2041 and is close to the third portion 203;

[0064] The length of the channel cavity 204 is less than the length of the sliding door 200;

[0065] The depth of the first through cavity 2041 is greater than the depth of the second through cavity 2042; the channel cavity 204 divides the sliding door 200 into a first sandwich layer 206 and a second sandwich layer 207;

[0066] A chuck 260 is also clamped inside the first through cavity 2041; the thickness of the chuck 260 is less than the depth of the first through cavity 2041 and greater than the depth of the second through cavity 2042; the chuck 260 further includes a plurality of fourth pulling ropes 205. One end of each of the plurality of fourth pulling ropes 205 is fixedly connected to the chuck 260, and the other end is fixedly connected to the second sandwich layer 207 and is located at the middle position of the first opening 104.

[0067] Specific implementation process of this embodiment: When the sliding door 200 is in the closed state, the air extraction member 250 is used to make the housing cavity 101 in a negative pressure state. At this time, the second sandwich layer 207 will be compressed towards the direction of the dual-channel spectrometer main body 300. The compression of the second sandwich layer 207 drives the fourth pull rope 205 to be pulled towards the direction of the dual-channel spectrometer main body 300. The fourth pull rope 205 pulls the chuck 260 to move towards the other end of the fourth pull rope 205, and the chuck 260 squeezes the communication part between the first through cavity 2041 and the second through cavity 2042, so that the communication part between the first through cavity 2041 and the second through cavity 2042 expands outwards under the extrusion force, providing an extrusion force for the first part 201 at the communication part between the first through cavity 2041 and the second through cavity 2042.

[0068] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0069] It can prevent the loosening problem of the first part 201 caused by vibration at the communication part between the first extrusion groove 131 and the second extrusion groove 132, thereby improving its airtightness.

[0070] Embodiment 3: In order to ensure the tightness of the compression surface where the first sandwich layer 206 contacts the first working head 121, and prevent the technical problem that the compression surface where the first sandwich layer 206 contacts the first working head 121 moves due to vibration, affecting the reduction of airtightness, the sliding door 200 is further improved, and the following technical solution is proposed, specifically:

[0071] As Figures 12 to 15 shown, a convex part 208 is provided at the bottom of the first sandwich layer 206, and the convex part 208 is close to the first through cavity 2041; and a convex part inner cavity 2081 is opened in the direction of the channel cavity 204 on the convex part 208, and a connection groove 2082 is also opened between the convex part 208 and the convex part inner cavity 2081. The convex part 208, the convex part inner cavity 2081 and the connection groove 2082 are all rectangular structures;

[0072] The connection groove 2082 further includes a connecting pipe 2083. One end of the connecting pipe 2083 is communicated with the connection groove 2082, and the other end is connected to the convex part inner cavity 2081; the other end of the connecting pipe 2083 is arc-shaped, and the other end of the connecting pipe 2083 is in a closed state without external force.

[0073] Specific implementation process of this embodiment: When the sliding door 200 is in the closed state, the air extraction member 250 extracts air from the housing cavity 101, making the inside of the housing cavity 101 in a negative pressure state. During the process of the housing cavity 101 becoming in a negative pressure state, the first sandwich layer 206 compresses towards the direction of the dual-channel spectrometer main body 300, causing the convex portion 208 to be stretched and deformed towards the working port 120. At the same time, the inner cavity 2081 of the convex portion, the connecting groove 2082, and the connecting pipe 2083 are all stretched and deformed. After the connecting pipe 2083 is initially stretched, the opening at the other end of the connecting pipe 2083 is stretched open, and its opening leads to the inside of the housing cavity 101. At this time, the first sandwich layer 206 rebounds a small distance in the opposite direction of the dual-channel spectrometer main body 300; the air extraction member 250 continues to extract air from the housing cavity 101. After the opening at the other end of the connecting pipe 2083 leads to the housing cavity 101, it will cause the air extraction member 250 to extract air from the inner cavity 2081 of the convex portion, making the inner cavity 2081 of the convex portion also in a negative pressure state; the negative pressure inner cavity 2081 of the convex portion adsorbs the first working head 121. When the air extraction member 250 continues to extract air from the housing cavity 101, the connecting pipe 2083 is stretched again, and the inner cavity 2081 of the convex portion is squeezed by the first working head 121 during the adsorption process. When the inner cavity 2081 of the convex portion completely adsorbs the first working head 121 tightly, at this time, the first sandwich layer 206 is subjected to the squeezing force of the first working head 121, causing the opening at one end of the connecting pipe 2083 to be tightly closed under the squeezing force of the first working head 121; after the opening at one end of the connecting pipe 2083 is tightly closed, the air extraction member 250 continues to extract air from the housing cavity 101, making the first sandwich layer 206 adsorb on the arc surface of the first working head 121.

[0074] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0075] By adsorbing the first working head 121 through the inner cavity 2081 of the convex portion and the first sandwich layer 206, a dual adsorption effect is achieved, effectively preventing the tightness of the compression surface where the first sandwich layer 206 contacts the first working head 121, and preventing the problem that the compression surface where the first sandwich layer 206 contacts the first working head 121 moves due to vibration, thereby improving its airtightness.

[0076] Embodiment 4: Since dust may accumulate in the channel groove 130 during use, the dust will form an air passage between the sliding doors 200 in the channel groove 130, resulting in poor sealing and reducing its airtightness; therefore, the housing 100 is improved, and the following technical solution is proposed, specifically:

[0077] As Figures 16 to 21 shown, the housing 100 further includes a plurality of refrigeration components 280, and the refrigeration components 280 are divided into a semiconductor refrigeration chip 281 and a heat dissipation end 282;

[0078] A plurality of the refrigeration components 280 are fixedly connected to the bottom of the channel groove 130 and arranged at equal intervals, and the refrigeration components 280 are close to the first extrusion groove 131;

[0079] The semiconductor refrigeration sheet 281 communicates with the channel groove 130, and the heat dissipation end 282 communicates with the shell cavity 101;

[0080] The sliding door 200 further includes a plurality of iron bars 290; the iron bars 290 are fixedly connected inside the first interlayer 206 and are equidistantly distributed around the rectangular structure of the inner cavity 2081 of the convex part;

[0081] A collection groove 123 is further formed near the working port 120. The collection groove 123 has an arc-shaped structure, and the length of the collection groove 123 is equal to the length of the first extrusion groove 131.

[0082] Specific implementation process of this embodiment: When working in a lower environment (5°C to 9°C), start the refrigeration component 280 before the sliding door 200 is closed, so that the semiconductor refrigeration sheet 281 on the refrigeration component 280 forms condensed water with the air, and then close the rotation of the motor 210 to pull the sliding door 200, so that the sliding door 200 slides into the channel groove 130 under the action of the automatic rope winding member 231. At this time, the bottom surface of the sliding door 200 will contact the semiconductor refrigeration sheet 281, and the bottom of the sliding door 200 drives the condensed water to move in the channel groove 130, and the dust on the channel groove 130 moves into the collection groove 123 under the drive of the condensed water; when the sliding door 200 is closed on the working port 120, pull the second handle 107 to make the air extraction member 250 extract air from the shell cavity 101. At this time, the heat dissipation end 282 of the refrigeration component 280 is still heating the shell cavity 101. When the inner cavity 2081 of the convex part and the first interlayer 206 are adsorbed on the first working head 121, turn off the refrigeration component 280. At this time, the increased temperature in the shell cavity 101 will be transferred to the first interlayer 206 and the iron bars 290. Through the heat transfer of the iron bars 290, the first interlayer 206 around the iron bars 290 will be heated up to improve the elasticity of the first interlayer 206, preventing the elasticity of the first interlayer 206 from being insufficient due to the low temperature, thereby affecting its airtightness; and the iron bars 290 expand slightly when heated, which will make the first interlayer 206 fit more closely with the first working head 121 and improve the adsorption effect.

[0083] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0084] Condensate is formed by the air and the semiconductor refrigeration sheet 281. The condensate contacts the sliding door 200 to improve the tightness, thereby enhancing its airtightness. Moreover, the port of the heat dissipation end 282 communicates with the shell cavity 101. The heat dissipation of the semiconductor refrigeration sheet 281 is transferred to the shell cavity 101 through the heat dissipation end 282, causing the temperature in the shell cavity 101 to rise. At a relatively low temperature, the temperature in the shell cavity 101 can be increased through the heat dissipation end 282. Through the heat transfer of the iron bar 290, it is prevented that the elasticity of the first interlayer 206 is insufficient due to the low temperature. The iron bar 290 expands slightly when heated, which will make the first interlayer 206 fit more closely with the first working head 121 and improve its adsorption effect.

For those skilled in the art, various changes and modifications can be made to the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
